PowerPoint Presentation On Heart Attack

PPT On Heart Attack

Download

Description:
1. Let's say it's 6.15pm and you're driving home (alone of course) after an unusually hard day on the job.
You're really tired, and frustrated……

2. YOU ARE REALLY STRESSED AND UPSET ….
Suddenly you start experiencing severe pain in your chest that starts to radiate out into your arm and up into your jaw.
You are only five miles from the hospital nearest your home.
Unfortunately you don't know if you'll be able to make it that far

3. WHAT TO DO ???
YOU HAVE BEEN TRAINED IN CPR, BUT THE GUY THAT CONDUCTED THE COURSE DID NOT TELL YOU HOW TO PERFORM IT ON YOURSELF !!!

4. HOW TO SURVIVE A HEART ATTACK WHEN ALONE?
SINCE MANY PEOPLE ARE ALONE WHEN THEY SUFFER A HEART ATTACK, WITHOUT HELP, THE PERSON WHOSE HEART IS BEATING IMPROPERLY AND WHO BEGINS TO FEEL FAINT, HAS ONLY ABOUT 10 SECONDS LEFT BEFORE LOSING CONSCIOUS

5. ANSWER:
DO NOT PANIC, BUT START COUGHING REPEATEDLY AND VERY VIGOROUSLY.
A DEEP BREATH SHOULD BE TAKEN BEFORE EACH COUGH, THE COUGH MUST BE DEEP AND PROLONGED, AS WHEN PRODUCING SPUTUM FROM DEEP INSIDE THE CHEST.
A BREATH AND A COUGH MUST BE REPEATED ABOUT EVERY TWO SECONDS WITHOUT LET-UP UNTIL HELP ARRIVES, OR UNTIL THE HEART IS FELT TO BE BEATING NORMALLY AGAIN.

6. DEEP BREATHS GET OXYGEN INTO THE LUNGS AND COUGHING MOVEMENTS SQUEEZE THE HEART AND KEEP THE BLOOD CIRCULATING. THE SQUEEZING PRESSURE ON THE HEART ALSO HELPS IT REGAIN NORMAL RHYTHM. IN THIS WAY, HEART ATTACK VICTIMS CAN GET TO A HOSPITAL

7. TELL AS MANY OTHER PEOPLE AS POSSIBLE ABOUT THIS.
IT COULD SAVE THEIR LIVES !!! DON'T EVER THINK THAT YOU ARE NOT PRONE TO HEART ATTACK AS YOUR AGE IS LESS THAN 25 OR 30. NOWADAYS DUE TO THE CHANGE IN THE
LIFE STYLE, HEART ATTACK IS FOUND AMONG PEOPLE OF ALL AGE GROUPS.
BE A FRIEND AND PLEASE SEND THIS ARTICLE TO AS MANY FRIENDS AS POSSIBLE

PowerPoint Presentation On NANOBOTS

PPT On NANOBOTS

Download

Description:
1. NANOBOTS-The Future Doctor
PRESENTED BY:
N.RAGA SWAROOPA
II YEAR EEE

2. Nano:
A prefix that means very, very, small.
The word nano is from the Greek word ‘Nano’ meaning Dwarf. It is a prefix used to describe "one billionth" of something, or 0.000000001.

3. Nano science
A part of science that studies small stuff.
It’s not biology, physics or chemistry. It’s all sciences that work with the very small.

4. Nanotechnology
The art and science of making useful stuff that does stuff on the nanometer length scale.

5. NANOROBOTS
The tiniest of computers need to have the smallest of processors in order to make light and small computers more accessible.
This will require smaller and smaller wiring capabilities. The smallest of wiring materials is engineered by the nanotechnology.
The 1980s and early 1990s saw a significant increase in the popularity of nanotechnology. This is the science that can figure out how to power our lives with nothing more than molecules and atoms.

6. HOW ARE NANOROBOTS MADE?
The ultimate goal and essential definition of a nanorobot is to have the microscopic entity made entirely out of electromechanical components.
Humans are able to perform one nano-function at a time , but the thousands of varied applications required to construct an autonomous robot would be exceedingly tedious for us to execute by hand, no matter how high-tech the laboratory.
The ideal nanobot consists of a transporting mechanism , an internal processor and a fuel unit of some kind that enables it to function.

7. The main difficulty arises around this fuel unit. One possible solution is to adhere a fine film of radioactive particles to the nanobot’s body. As the particles decay and release energy the nanobot would be able to harness this power source.
The other problem is with the construction of a nanorobot. Metal that might be used for the robot’s construction behaves one way in relatively large quantities and a completely different way on the nano scale.
Microscopic silicon components called transducers have so far been successfully built into nanorobot legs.

8. Scientists are hard at work on designing a body built out of transducers; they are encountering slight problems in agreeing on what the final shape of the standard nanobot should be.
Very few researchers support the humanoid design.
They hope that by equipping the nanobot with several sets of fast-moving legs and keeping its body low to the ground , they can create a quick, efficient machine that would also be suitably shaped for introduction into human blood vessels to perform functions such as clearing away built-up cholesterol or repairing tissue damage.

9. A robot this small can actually interact with materials on their molecular and atomic level.
They could rebuild tissue molecules in order to close a wound, or rebuild the walls of veins and arteries to stop bleeding and save lives. They could make their way through the bloodstream to the heart and perform heart surgery molecule by molecule without many of the risks.
Likewise, researchers hope that nanorobots will have many miraculous effects on brain research, cancer research, and finding cures for difficult diseases.

10. REPAIRING OF DAMAGED TISSUES BY NANOBOTS:
The medical science wants to create nanobots that can repair damaged tissue without pain and trauma. Many of the medical procedures we employ today are very traumatic to the human body and do not work in harmony with our natural systems.
Nanorobots are so small that they actually interact on the same level as bacteria and viruses do, and so they are capable of building with the very particles of our bodies: atoms and molecules.

11. Patients may be allergic to anesthetics, during an organ transplant their body may mysteriously reject the new organ , leading to death.
And in the case of a tumor operation, even a few microscopic missed cells can constitute complete failure to battle the cancer. The drug which is supposed to cure you may actually leave many parts of your body in worse shape than they were before.
Nanorobots, on the other hand, will typically measure only about six atoms wide. It is anticipated that they could be equipped with all sorts of tools and cameras in order to furnish more extensive information about the human body.

12. Nanorobots could be used to clear built-up cholesterol from your arteries, thereby saving you from a heart attack. When it comes to major unsolved diseases like cancer, nanorobots are perfect for eradicating malignant cells.
Scientists are already hard at work on nanobots that can identify and destroy cancer at its growth site so that no trauma is inflicted anywhere else in the body.
They could also perform delicate surgical functions such as closing a split vein. Regardless of the individual details, it seems clear that the advent of the nanobot is destined to change the face of medicine forever.

13. WHAT NANOBOTS ARE MADE OF?:
Traditionally, most robots have a solar cell or some kind of battery pack, but obviously these are many times too large for nanorobot. However, the answer may lie in nuclear technology.
Researchers consider it highly likely that when equipped with a thin film of radioactive material, nanobots will be able to fuel themselves on particles released by decaying atoms. This fuel technology is easily scaled down to nano-size.
Silicon has always been the first choice for delicate electronics and has the right qualities to make a successful scaled-down robot, even one as tiny as a few hundred nanometers. It is strong enough to last and conduct electricity.

14. However, constructing nanobots out of silicon would subject them to the same issues that other silicon electronics face , one of which is that they are not biodegradable. They would still be another small drain on our natural resources.
U.C. Berkeley affiliate Kris Pister invented a solar-powered robot that measures only 8.5 millimeters and can walk slowly on two “legs” like humans do.
Pister composed his robot primarily of tiny silicon pieces called transducers which are capable of taking the energy generated by the robot’s solar cell and turning it into mechanical power.

15. Prototypes have been built using biological components, but the ultimate goal is to achieve a purely electromechanical model.
In the middle stage of our nanobot development we will probably see high-production nano-factories emerge, which can then in turn produce an ultimate nanorobot: a fully mechanical, voice-programmed microscopic machine capable of performing a wide array of useful functions.
Scientists consider this the end goal in all nano technological research, and expect that it will take several stages to get there. So, in other words, fans of the ideal nanorobot may have to wait. But eventually we will have this ultimate technology and all of its amazing capabilities at our disposal.

16. APPLICATIONS OF NANOROBOTS:
1.BLUE BRAIN :
The name of the world’s first virtual brain. That means a machine that can function as human brain. The IBM is now developing a virtual brain known as the BLUE BRAIN.
A machine that can function as brain .
It can take decision.
It can respond.
It can keep things in memory.
Nanobots could carefully scan the structure of our brain , providing a complete readout of the connection. The neocortex is the largest and most complex part of the human brain, and constitutes about 85 percent of the brain's total mass.

17. The neocortex is thought to be responsible for the cognitive functions of language, learning, memory and complex thought.
The simulated neurons will be interconnected with rules the team has worked out about how the brain functions. This result would develop a simulated model known as “Blue brain”
The main aim of blue brain is to build an software replica or template which could reveal many existing aspects of the brain circuits, memory capacity, and how memories are lost.
The Blue Brain simulation uses one microprocessor for each of the 10,000 neurons in the cortical column of a rat's cerebral cortex. It helps to build a brain microcircuit, in order to scale it in human brain.

18. 2. BLOODSTREAM :
Scientists at Micro/Nano physics Research Laboratory at Australia’s Monash University have developed tiny nanobot micro motors that are a mere quarter of a millimeter, powered by tiny piezoelectric motors, capable of swimming in the human bloodstream. While the team is still devising ways to remote control the new robots. They feel that they have a solid solution for an autonomous motor design in the form of piezoelectric. In the human body, the flow of blood provides abundant kinetic energy.

19. While a nanobot is too small to likely have a useful battery,it could exploit this kinetic energy to power tiny micro motors, the goal of the Australian researchers.

20. Conclusion
Nanobots will be the next generation of nano machines.
Advanced nanobots will be able to sense and adapt to environmental stimuli such as heat, light, sounds,surface textures, and chemicals; perform complex calculations; move, communicate, and work together; conduct molecular assembly; and, to some extent, repair or even replicate themselves.
The field of nanotechnology and holotechnology  will overlap in the design of projection screens and user interfaces of the next generations of the holographic cellphones,and televisions.
More virtual Reality.

PowerPoint Presentation On Green Revolution

PPT On The Green Revolution

Download

Description:
1. The Green Revolution.

2. Why? When?
The green revolution applies to many third world countries, but the most successful experiment was the one in India.

Here the Bengal Famine, (the world's worst recorded food disaster) happened in 1943. An estimated four million people died of hunger that year alone in eastern India.

It was therefore natural that food security was a paramount item on free India's agenda. This awareness led to the Green Revolution in India. However, the term "Green Revolution" is applied to the period from 1967 to 1978. Between 1947 and 1967, efforts at achieving food self-sufficiency were not entirely successful.

Efforts until 1967 largely concentrated on expanding the farming areas. But starvation deaths were still being reported. In a perfect case of Malthusian economics, population was growing at a much faster rate than food production. This called for drastic action to increase yield. The action came in the form of the Green Revolution.

3. What was the Green Revolution in India?

There were three basic elements in the method of the Green Revolution:

1) Continued expansion of farming areas.

2) Double-cropping existing farmland.

3) Using seeds with improved genetics.

4. Continued expansion of farming areas.
The area of land under cultivation was being increased right from 1947, but this was not enough in meeting with the rising demand.

Other methods were required to increase resources. Yet, the expansion of cultivable land also had to continue.

So, the Green revolution continued with this quantitative expansion of farmlands, even though it was not the most striking feature of the revolution.

5. Double-cropping existing farmland
Double-cropping was a primary feature of the Green Revolution.
Instead of one crop season per year, the decision was made to have two crop seasons per year. The one-season-per-year practice was based on the fact that there is only natural monsoon per year.

So, there had to be two "monsoons" per year. One would be the natural monsoon and the other an artificial 'monsoon’.
The artificial monsoons were created by huge irrigation facilities. Dams were built to arrest large volumes of natural monsoon water which were earlier being wasted. Simple irrigation techniques were also adopted.

6. Using seeds with improved genetics
This was the scientific aspect of the Green Revolution. The Indian Council for Agricultural Research was re-organized in 1965 and then again in 1973.

It developed new strains of high yield value (HYV) seeds, mainly wheat and rice but also millet and corn. The most noteworthy HYV seed was the K68 variety for wheat.

The credit for developing this strain goes to Dr. M.P. Singh who is also regarded as the hero of India's Green revolution.

7. Advantages:
1) The Green Revolution resulted in a record grain output of 131 million tons in 1978-79. This established India as one of the world's biggest agricultural producers. No other country in the world which attempted the Green Revolution recorded such level of success. India also became an exporter of food grains around that time.

2) Yield per unit of farmland improved by more than 30 per cent between 1947 and 1979 when the Green Revolution was considered to have delivered its goods.

3) The crop area under HYV varieties grew from seven per cent to 22 per cent of the total cultivated area during the 10 years of the Green Revolution. More than 70 per cent of the wheat crop area, 35 per cent of the rice crop area and 20 per cent of the millet and corn crop area, used the HYV seeds.

4) Crop areas under high-yield varieties needed more water, more fertilizer, more pesticides, fungicides and other chemicals. This spurred the growth of the local manufacturing sector. Such industrial growth created new jobs and contributed to the country's GDP.

5) The increase in irrigation created need for new dams to harness monsoon water. The water stored was used to create hydro-electric power. This in turn boosted industrial growth, created jobs and improved the quality of life of the people in villages.

6) India paid back all loans it had taken from the World Bank and its affiliates for the purpose of the Green Revolution. This improved India's creditworthiness in the eyes of the lending agencies.

7) Some developed countries, especially Canada, which were facing a shortage in agricultural labour, were so impressed by the results of India's Green Revolution that they asked the Indian government to supply them with farmers experienced in the methods of the Green Revolution. Many farmers from India were thus sent to Canada where they settled. These people remitted part of their incomes to their relatives in India. This not only helped the relatives but also added to India's foreign exchange earnings.

8. Disadvantages:
1) Even today, India's agricultural output sometimes falls short of demand. The Green Revolution, howsoever impressive, has thus not succeeded in making India totally and permanently self-sufficient in food. In 1979 and 1987, India faced severe drought conditions due to poor monsoon; this raised questions about the whether the Green Revolution was really a long-term achievement. In 1998, India had to import onions, due to a lack of crops.

2) India has failed to extend the concept of high-yield value seeds to all crops or all regions. In terms of crops, it remains largely confined to food grains only, not to all kinds of agricultural produce. In regional terms, only Punjab and Haryana states showed the best results of the Green Revolution. The eastern plains of the River Ganges in West Bengal state also showed reasonably good results, but others were less impressive in other parts of India.

9. Conclusion
Nothing like the Bengal Famine can happen in India again. But even today, there are places like Kalahandi where famine-like conditions have been existing for many years and where some starvation deaths have also been reported. This is due to some reasons other than availability of food in India, but the very fact that some people are still starving in India (whatever the reason may be), brings into question whether the Green Revolution has failed in its social objectives.

So, overall I feel that the Green revolution, in this case in India, has not been 100% successful, even though it has been a resounding success in terms of agricultural production.

Recent Trends in Telecommunication Sector

PPT On Recent Trends in Telecommunication Sector

Download

Description:
1. “Recent Trends in Telecommunication Sector”
www.studygalaxy.com

2. INTRODUCTION TO TELECOMMUNICATION  
Telecommunications is the transmission of data and information between computers using a communications link such as a standard telephone line.
1994 was a watershed in the history of Indian telecom sector, which ranked sixth in the world after USA, china, Japan, Germany, and France in terms of number of installed fixed lines.
That year saw the introduction of new telecom policy (ntp) of government of India that envisaged a vast change in Indian telecom scenario and reflected the government’s desire to bring Indian telecom at par with the rest of the world.
This policy change was followed up by a large number of other initiatives, including introduction of ntp 1999 that indicated continuing commitment of the government to liberalize the sector.

3. HISTORY OF THE TELECOM SECTOR IN INDIA
The telegraph act of 1885 governed the telecommunications sector. Under this act, the government was in-charge of policy making and provision of services.
Major changes began in the 1980s.
Under the Seventh Plan (1985-90), 3.6 percent of total outlay was set aside for communications
And since 1991, more than more than 5.5 percent is spent on it.
The initial phase of telecom reforms began in 1984 with the creation of Center for Department of Telematics (C-DOT) for developing indigenous technologies and private manufacturing of customer premise equipment.

4. Growth of Telecom in India
1994 - National Telecom Policy – 1994 announced
1997 - Telecom Regulatory Authority of India was setup
March 1999 - National Telecom Policy – 99 announced
2000 - TRAI Act amended & separate tribunal proposed
Oct-2002BSNL entered in to GSM cellular operation
19th October, 2002. Made incoming call free & initiated tariff equalization process
Nov 2003 Unified Access (Basic & Cellular) Service License (USAL) introduced as a first step
Recently 3G technology was launched by BSNL in India in 2008.
India is 4th largest market in Asia after china, japan and south Korea

5. Services
Electronic mail (e-mail)
Voice mail
Internet
Facsimile (fax)
Videoconferencing
General Packet Radio Service (GPRS
Multimedia Messaging Service (MMS)
Dial-in Services
Short Messaging Services (SMS)
Other Services

6. Target Measure in 11th plan for Telecommunication Sector
Focus on making India a regional Telecom manufacturing hub.
FDI limit increased from 49% to 74%
100% FDI permitted under automatic route in the manufacturing sector
Deregulation virtually complete and Unified Licensing regime
Interconnection Usage Charge framework in place
Exemption from customs duty for import of Mobile Switching Centers
Comprehensive Spectrum policy and 3G policy on the anvil

7. Conclusion
Private players in the telecom industry are performing far better than the public players i.e., MTNL and BSNL
Looking at the competition trend, it seems that soon in future, rural schools will be having broadband and internet facilities as their part of studies as well as routine lives.

PowerPoint Presentation On Contract Farming

Contract Farming PPT

Download

Description:
1. Contract Farming
One Option For Creating A Role For The Private Sector In Agriculture Development?
www.studygalaxy.com

2. What Is Contract Farming ?
ESSENTIALLY
The Farmer Is Contracted to Plant the Contractor’s Crop on His Land
Harvest and Deliver to the Contractor, a Quantum of Produce, Based Upon Anticipated Yield and Contracted Acreage
This Is at a Pre Agreed Price
Towards These Ends, the Contractor May or May Not Supply the Farmer With Selected Inputs

3. ELEMENTS OF CONTRACT FARMING
PRE – AGREED PRICE
QUALITY
QUANTITY
TIME

4. What Else Did It Do?
Mono-culture,over fertilization & excessive water usage
Soil degradation..
Singular focus on supported crops discourages diversification.
Subsidized exports to liquidate stock creates a further distance between the international market & domestic reality.
To succeed in this context contract farming needs to go well beyond its simple definition

5. Why Contract Farming ?
To reduce the load on the central & state level procurement system.
To increase private sector investment in agriculture.
To bring about a market focus in terms of crop selection by Indian farmers.
To generate a steady source of income at the individual farmer level.
To promote processing & value addition.
To generate gainful employment in rural communities, particularly for landless agricultural labor.
To flatten as far as possible, any seasonality associated with such employment.
To reduce migration from rural to urban areas.
To promote rural self-reliance in general by pooling locally available resources & expertise to meet new challenges.

6. Moving From Food Security To Market Demand

7. Moving To A Value Delivery Sequence

8. The Advantages Of Contract Farming
To The Farmer
Exposure To World Class Mechanized Agro Technology.
Obtains An Assured Up Front Price & Market Outlet For His Produce.
No Requirement To Grade Fruit, As Mandatory For Fresh Market Sale.
Bulk Supplies Versus Small Lots As Again Reqd By The Fresh Market.
Crop Monitoring On A Regular Basis. Technical Advice, Free Of Cost At His Doorstep.
Supplies Of
Healthy Disease Free Nursery
Agricultural Implements
Technical Bulletins Etc
Remunerative Returns

9. The Advantages Of Contract Farming
To The Company:
Uninterrupted & Regular Flow Of Raw Material.
Protection From Fluctuation In Market Pricing.
Long Term Planning Made Possible.
Concept Can Be Extended To Other Crops.
Builds Long Term Commitment
Dedicated Supplier Base
Generates Goodwill For The Organization.

10. Contract Farming - Industry Related Issues
Honoring Contracts - there is no credible enforcement mechanism in place.
Small size of land holdings.
Need to contract with a larger number of farmers, thereby increasing risk.
Lack of a comprehensive crop insurance scheme

11. Some Suggestions To Promote Contract Farming
Contract farming organizations are allowed to take out realistic & deregulated crop insurance policies.
Facilitate import of varieties / hybrids for contract farmers. Growth will be led by productivity enhancement & market focus.
Research system synergy with both farmers & private sector

12. In Conclusion
India, given the diverse agro climatic zones, can be a competitive producer of a large number of crops.
Need to convert our factor price advantage into sustainable competitive advantage.
Contract farming offers one possible solution.

13. Thank You.

PowerPoint Presentation On XML

PPT On XML

Download

Description:
1. Extensible Markup Language

2. XML Is A W3C Standard
First official XML specification (1.0) published in February 1998.
XML is upper version of HTML.

3. A method for putting structured data in a text file. Uses tags to specify certain rules. Used with a processing application that knows how to handle tags.

4. XML is meta language that describe the content of document
Java = portable program
XML = portable data
XML does not specify the tag set or grammar of the language

5. The “X” in XML
eXtensible.
Tags are defined by the person creating the document.
Tag sets have been developed for specialized topics.
–Chemistry, math, music, libraries, calendar events, addresses, etc.

6. Key Uses Of XML
Data storage
Data exchange
Document publishing

7. XML: Data Storage
Searching the data is relatively easy.
Format is standard.
Standard tools for input/output and validation exist.
Easy to read files makes debugging easier.

8. XML: Data Exchange
Data is relatively easy to read and edit with a simple text editor.
Complex relationships like trees and inheritance can be communicated.
Tags are self-describing, human readable.
Automatic data validation.

9. XML: Document Display
Meaning of tags is handled by XSL.
–Instructions for transforming one kind of document to another.
–Common transformation is XML to HTML
One XML may be linked to multiple XSL files.
–Content in one file can be rendered for the Web, print, smart phones, etc.
Separation of content from presentation.

10. Processing Applications
Processing applications
–Check that XML document meets standards for being “well formed”.
–Validate based on syntax defined in the DTD(Document Type Definition)
–Transform based on instructions in the XSL

11. Why XML?
Four different renderings generated from a single XML file.
–Graphical
–Text only
–Site map
–Quick links
Link consistency.

12. XML Examples
VT home page (top level university pages).
-One XML file stores all content, links
- XSL transforms the XML into HTML
Hokie Portal
–an XML-based syndication format

13. Why Use XML?
Allows for distributed content management.
Various university departments may “own” RSS channels.
Channel owners edit their content directly.
Webmaster controls display.
Automatic validation of RSS files.

14. When You Might Use XML

NATIONAL POLICY OF EDUCATION 1986

PPT On NATIONAL POLICY OF EDUCATION,1986

Download

Description:
1. On independence in 1947, MAULANA AZAD, India's first education minister recommended strong central government control over education throughout the country, with a uniform educational system.

2. Prime Minister Indira Gandhi
announced the first National Policy on Education in 1968
which called for a "radical restructuring" and equalize educational opportunities in order to achieve national integration and greater cultural and economic development.

3. NATIONAL POLICY OF EDUCATION,1986

4. NPE’86 BACKGROUND (NEED)
Problems of access, quality, quantity, utility and financial outlay
The general formulation is corporate in the 1968 policy did not get translated into detailed study of implementation.This new policy called for "special emphasis on the removal of disparities and to equalize educational opportunity,"

5. SALIENT FEATURES OF NPE’86
1) Important role of education.
2) National system of education.
3) Education for equality.
4) Reorganization of education at different levels.
5) Making the system work.

6. SALIENT FEATURES OF NPE’86
Important role of education
All round development
Developing Man-Power
A unique investment

7. National system of education
Concept of national system
Common educational structure
Understanding cultural & social system
National support for implementing programs.

8. There is a common educational structure(10+2+3) followed all over the country.

9. School education 10+2
Pre primary (FOR 1 YEAR) Primary (GRADE 1-5)
Middle (GRADE 6-8)
Secondary (GRADE 9-10)
Senior Secondary (GRADE11-12)

10. Education for equality.
For women
For SC & ST
For other educationally backward sections & minorities
For handicapped

11. This policy is especially for Indian women, Scheduled Tribes (ST) and the Scheduled Caste (SC) communities. To achieve these, the policy called for expanding scholarships, adult education, recruiting more teachers from the SCs, incentives for poor families to send their children to school regularly, development of new institutions and providing housing and services

12. EDUCATION FOR ALL
The current scheme for universalization of Education for All is the SARVA SHIKSHA ABHIYAN which is one of the largest education initiatives in the world.

13. The government is committed to providing education through mainstream schools for children with disabilities.
The need for inclusive education arises precisely because it is now well understood that most children with disabilities can, with motivation and effort on the part of teaching institutions, become an integral part of those institutions

14. Reorganization of education at different levels
Early childhood care & education
Primary education
Secondary education
Vocationalisation of education
Higher education

15. The Indian government lays great emphasis to primary education up to the age of fourteen years Education has also been made free for children for six to 16 years of age. Private schools shall admit at least 25% of the children in their schools without any fee.

16. The Mid-day Meal Scheme is the popular name for school meal programmed in India. It involves provision of lunch free of cost to school-children on all working days with an objective to:
increase school enrolment and attendance, improve socialization among children belonging to all castes and addressing malnutrition.

17. Role of NPE in Secondary Education
The (NPE), 1986, has provided for environment awareness, science and technology education, and introduction of traditional elements such as yoga into the Indian secondary school system

18. Making the system work
A better deal to teachers with greater accountability
Provision of improved student services
Provision of better facilities of institutions
Creating of a system of performance as per the national level

19. Implementation of NPE 1986
Operation blackboard
Restructuring & reorganization of teacher education
Non formal education
Vocationalisation of education

20. MERITS OF NPE’86
1) Deep concern had been shown by the prime minister in
formulation of NPE.
2) The nation wide debate was conducted for the formulation of
the policy.
3) The program of action was checked out.
4) The ministry of education was renamed as ministry of
Human Resource Development (HRD).

21. NPE is best policy for the development of education in remote areas especially for SC, ST, Handicapped, backward, minorities and women. Indian govt. introduced it for the development of nation and they got success on large extent.
People come closer by the help of education and now just because of this policy India’s education system is third largest system among all nations.

PowerPoint Presentation On Speaker Recognition

PPT On Speaker Recognition

Download 

Description:
1. STUDY OF SPEAKER RECOGNITION

2. INTRODUCTION
Speaker recognition is the process of automatically recognizing who is speaking on the basis of individual information included in the input speech waves.

This technique makes it possible to use the speaker’s voice to verify their identity and control access to services such as voice dialing, voice mail, telephone shopping, security control for confidential information areas and many more.

3. OBJECTIVE
To extract, characterize and recognize the information about speaker identity.

It consists of comparing a speech signal from an unknown speaker to a set of stored data of known speakers. The system can recognize the speaker, which has been trained with a number of speakers. This process determines who has spoken by matching input signal with pre- stored samples.

4. Principles of Speaker Recognition
The human speech contains numerous discriminative features that can be used to identify speakers. Speech contains significant energy from zero frequency up to around 5kHz. The speech signal is a slowly timed varying signal but when examined over a sufficiently short period of time, its characteristics are fairly stationery. Therefore, short-time spectral analysis is the most common way to characterize the speech signal.

5. Speaker recognition methods can be divided into

text-independent
text-dependent
In a text-independent system, task is to identify the person who speaks irrespective of what one is saying whereas in text-dependent system , the recognition of the speaker’s identity is based on his or her speaking one or more specific phrases, like passwords, PIN codes, etc.
Here we are describing text-independent speaker identification system.

6. Speaker recognition is basically identification and verification.

Speaker identification is the process of determining which registered speaker provides a given utterance, on the other hand verification is the process of accepting or rejecting the identity claim of a speaker.

Speaker recognition systems contain two main modules:
Feature extraction
Feature matching

Feature extraction is the process that extracts a small amount of data from the voice signal that can later be used to represent each speaker.
Feature matching involves the actual procedure to identify the unknown speaker by comparing extracted features from his/her voice input with the ones from a set of known speakers.

7. All speaker recognition systems have two distinguished phases:

Enrollment or training phase

It is the process of familiarizing the system with the voice characteristics of the speakers registering so that the system can build reference models for those speakers.

Input speech → feature extraction →generate reference model

Operational or testing phase

Testing is the actual recognition task. In this phase, the input speech is matched with stored reference models and a recognition decision is made.

Test speech→ feature extraction → comparison→ decision

Reference

 8. Speech Feature extraction

  It is Signal-processing front end :

In this sampled speech signal is converted into set of feature vectors which characterize the properties of speech that can separate different speakers, performed both in training and testing phases.

Here, Parametrical representation of speech signal is done using Mel-frequency Ceptrum coefficients(MFCC).

MFCC is based on the human peripheral auditory system. This technique uses two types of filters, linearly spaced filters and logarithmically spaced filters to capture the important characteristics of speech. This is expressed in the mel-frequency scale (linear frequency spacing below 1000Hz and a logarithmic spacing above 1000Hz).

9. Mel-frequency cepstrum coefficients processor

The main purpose of the MFCC processor is to mimic the behaviour of the human ear. The input speech signal is sampled and sampling frequency is chosen to minimize the effects of aliasing in the analog to digital conversion.

10. Framing
In this step the continuous speech signal is blocked into frames of N samples, with adjacent frames being separated by M (M < N). Windowing we window each individual frame so as to minimize the signal discontinuities at the beginning and end of each frame. The concept here is to minimize the spectral distortion by using the window to taper the signal to zero at the beginning and end of each frame.   Hamming window is used, which has the form: Fast Fourier Transform (FFT)   The next processing step is the Fast Fourier Transform, which converts each frame of N samples from the time domain into the frequency domain. The FFT is a fast algorithm to implement the Discrete Fourier Transform (DFT)

11. Mel-frequency Wrapping Human perception of the frequency contents of sounds for speech signals does not follow a linear scale. Thus, for each tone with an actual frequency, f, a subjective pitch is measured on a scale called the ‘mel’ scale.Filter bank has a triangular bandpass frequency response, and the spacing is determined by a constant mel frequency interval. Cepstrum In this final step, we convert the log mel spectrum back to time. The result is called the mel frequency cepstrum coefficients (MFCC).Because the mel spectrum coefficients (and so their logarithm) are real numbers, we can convert them to the time domain using the Discrete Cosine Transform (DCT).

12. Feature matching Vector quantization(VQ)approach is used for its ease of implementation and high accuracy. It is a process of mapping vectors from a large vector space to a finite no. of regions in that space. Each region is called a cluster and can be represented by its centre called codeword. The collection of codeword is called codebook. Codebook effectively reduces the amount of data by preserving the essential information of the original distribution.

3. INTRODUCTION OF PROJECT
This project is to develop a device that allows for a user to remotely control home appliances using a cellular phone.

This system will be a powerful and flexible tool that will offer this service at any time, and from anywhere .

The control system will include two separate units: the cellular phone, and the control unit.

There will be two operating environments. The cellular phone operates indoor and outdoor and control unit operates indoor.

4. INTRODUCTION OF MICROCONTROLLER
A microcontroller is an economical computer-on-a-chip.It is a small and low-cost computer ,which performes specific task.
Microcontroller has an input device in order to get the input and an output device (such as LED or LCD Display) to exhibit the final process.
The 8051 has three very general types of memory to effectively program the 8051 it is On-Chip Memory, External Code Memory, External RAM.
A microcontroller has a CPU(a microprocessor) in addition to fixed amount of RAM, ROM, I/O port and a timer all on single chip. therefore the designer cannot add any external memory, I/O ports or timer to it.

5. INTRODUCTION OF DTMF
The DTMF tone decoder IC converts the received tones to their respective binary values and then gives them as an input to the microcontroller.
Its filter section uses switched capacitor technology for both the high and low group filters and for dial tone rejection. Its decoder uses digital counting techniques to detect and decode all 16 DTMF tone pairs into a 4-bit.

6. The DTMF keypad is laid out in 4*4 matrix with each row representing a low frequency and each column representing a high frequency
The DTMF tone decoder IC’s internal architecture consists of a band split filter section which separates the low and the high tone of the received tone pair.

7. DTMF KEYPAD FREQUENCIES

8. INTRODUCTION OF MAX 232

The Max 232 is a dual driver/receiver that includes a capacitive voltage generator to supply EIA-232 voltage levels from a single 5V supply.

The MAX 232 is to connect a serial port device to a serial port which uses the RS232 standard

The serial port device is usually a UART(universal asynchronous receiver/transmitter)

9. WORK DETAIL

This project is to develop a device that allows for a user to remotely control home appliances using a cellular phone.

The system requires two phones out of which the one present at the control unit has to be a cell phone with auto answer facility.

The person who wants to switch on/off any device makes a call from mobile phone.

Once the call gets picked up, presses the key for a corresponding device.

The mobile phone on the receiver side picks up the phone automatically after 5seconds, and then makes the tones available to the DTMF tone decoder IC through the headphone jack of the phone.

10. The DTMF tone decoder IC converts the received tones to their respective binary values and then gives them as an input to the microcontroller.

DTMF verifies both the frequency and duration of the received tones and pass the resultant 4-bit code to the output bus.

The output from DTMF IC is given into the MICROCONTROLLER 8051.

11. RESULT & CONCLUSION
We have successfully completed the project “DEVICE ON OFF THROUGH MOBILE PHONE”
This project is very useful now a days as well as its cost is very low, so anyone can afford it and use it.

Description:
1. CREATING NEW WORLD USING BIOTECHNOLOGY

2. The colloquial term "designer baby" refers to a baby whose genetic makeup has been artificially selected by genetic engineering combined with in vitro fertilization to ensure the presence or absence of particular genes or characteristics. The term is derived by comparison with "designer clothing".

3. Designer babies Since the discovery of DNA in the late 1950's, the possibility of genetic modification of animals and plants has become a reality. The term designer baby refers to the genetic modification of the child in it's early fetal life. The world of genetic modification has long moved on from the days of Dolly the Sheep.

4. parents will be able to select or design desired traits for their children. Boy or girl? Blond or brunette? Blue eyes or brown?

5. moms and dads pick whether junior has blue or brown eyes or black or blond hair. some known genetic markers do correlate with a probability of hair, eye and skin color,

6. "Our goal in offering (embryo screening) to couples at risk is to increase the likelihood that they can achieve their dream of having a healthy baby, free from a catastrophic genetic disease

7. Inherited Genetic Disorders
Tay-Sachs disease
Sickle-cell anemia
Cystic fibrosis
Hemophilia
Huntington’s Disease
Down’s Syndrome

8. Artificial Reproductive Technology

9. Reproductive Technology

10. What should we test for?
Genetic disorder 700 inherited conditions 344 test clinically available 211 prenatal tests offered
Traits
Gender

11. Embryo Selection is a relatively simple process. An ovarian biopsy can yield many eggs which can be fertilized in vitro with the partner’s sperm. The cells can be grown in culture, and at the eight cell stage, one of the cells can be removed for diagnosis.

12. How is it done?
The removal of one cell allows DNA tests to be performed on the embryo. The embryo with the desired trait can then be selected.
The final step is implanting the embryo into the uterus, and letting the pregnancy continue to term.
This process is called in vitro fertilization.

13. Invitro Fertilization (IVF) & Pre-Implantation Genetic Diagnosis (PGD)

14. What is IVF?
Use of artificial techniques to join an ovum with sperm outside (in vitro) woman's body to help infertile couples to have a children of their own. The basic technique of IVF involves removing ova from a woman's ovaries, fertilising them in the laboratory, and then inserting them into her uterus.
The first ‘test-tube baby’, Mary Louise Brown, was born in England in 1978.

15. Process of IVF
Hyper ovulation
Egg Retrieval
Artificial Insemination
Embryo Transfer

16. The embryos with faulty genes are discarded and only healthy ones are implanted in the mother's womb. The technique involves fertilizing eggs in a laboratory. When the embryos are three days old, scientists take out a cell from it and analyze it. If they find that the cell has an abnormal chromosome, the embryo is discarded as it will lead to babies with genetic defects

17. Viable and Desirable?
“This information is helping parents choose which embryos they want--and which to reject as unhealthy, or merely undesirable.”

18. Pre-implantation Genetic Testing
in vitro fertilization (IVF) Allow fertilized cells to divide until 8 cells – 3 days
Remove single cell for diagnosis within 15 hours Decide whether or not to implant

19. What is PGD?
Preimplantation Genetic Diagnosis. A procedure to analyze the genetic makeup of an embryo before it is implanted. The purpose is to identify disorders and genetically inherited diseases (Downs Syndrome, hemophilia, etc) as well as identify the gender.

20. Why Should I have PGD done?

Some of the most common reasons for having the PGD procedure are:

Three or more miscarriages in early pregnancy More than two unsuccessful IVF treatments Family Balancing If scientists are aware of the sex of an embryo while it remains still in their care, measures can be taken to assure that only embryos of a selected gender are returned to the womb for the possible establishment of pregnancy. While in vitro fertilization with PGD is only one of the methods for sex predetermination offered by our Center, it is the only procedure where success rates are higher than 99.9%.

21. preimplantation genetic diagnosis
PGD also known as embryo screening refers to procedures that are performed on embryos prior to implantation, sometimes even on oocytes prior to fertilization.
PGD is considered another way to prenatal diagnosis.
Its main advantage is that it avoids selective pregnancy termination as the method makes it highly likely that the baby will be free of the disease under consideration.

22. PGD
In the first group PGD is used to look for a specific disorder in couples with a high risk of transmitting an inherited condition.
This can be a monogenic disorder, meaning the condition is due to a single gene only, (autosomal recessive, autosomal dominant or X-linked disorders) or a chromosomal structural aberration (such as a balanced translocation).

23. PGD helps these couples identify embryos carrying a genetic disease or a chromosome abnormality, thus avoiding the difficult choice of abortion. In addition, there are infertile couples who carry an inherited condition and who opt for PGD as it can be easily combined with their IVF treatment

24. To be tested and prevented as well
Deafness, Shortness in height, learning disabilities?
Gender
“Gay Gene

25. Specific disorders
PGD is available for a large number of monogenic disorders. The most frequently diagnosed autosomal recessive disorders are cystic fibrosis, Beta-thalassemia, sickle cell disease and spinal muscular atrophy type 1.
The most common dominant diseases are myotonic dystrophy, Huntington's disease and Charcot-Marie-Tooth disease; and in the case of the X-linked diseases, most of the cycles are performed for fragile X syndrome, haemophilia A and Duchenne muscular dystrophy.

26. Embryo Screening with PGD
Recent advances in the fields of genetics, genetic diagnosis, embryo biopsy and preimplantation genetic diagnosis (PGD) have opened up a new world of opportunity for couples interested in achieving a healthy pregnancy.

30. The birth of the first British baby genetically screened before conception to be free of a breast cancer gene of creating so-called designer babies

31. In the future, the ability to identify many more genes for different neurological, psychiatric, and behavioral traits and disorders before uterine implantation may present opportunities for parents to "design" their children, selecting in or out the desired physical, intellectual, and temperament traits they desire.

32. selecting the child's genetic make-up based on parental preferences is the right decision.
It is possible that the world into which these designed children grow changes its values, leaving these genetically-designed children at a new disadvantage. Parents who have a socially undesirable trait, like deafness, may choose to reify their own existence by not sparing their children this trait, or even selecting for it, but the children may grow to resent their parents for it, wanting to be more like the norm.
Other children may be "designed" to be genetically similar at the HLA locus to a sibling with a condition that can be "cured" with a bone marrow transplant..

36. First "designer baby" born free of breast cancer genetic risk
‘BRCA1-free’ birth to designer babies”

37. Her parents had undergone a form of in vitro fertilisation (IVF), which meant that, unlike the father’s family, the baby was free of a breast cancer-causing mutation that had plagued the women of his family for generations

38. Every woman across three generations of the father’s family had previously been diagnosed with aggressive breast cancer, many in their 20s. Tests had shown that the family carried a faulty copy of the BRCA1 ‘high-risk’ breast cancer gene.

39. Although BRCA1 mutations are rare in the population as a whole, between five and eight out of ten carriers of this gene fault will go on to develop breast cancer, often at a young age (compared to an overall risk of one-in-nine of the general population). And, as is often the case with early-onset breast cancer, BRCA1 tumours will often be extremely aggressive.
So the couple took the decision to use the latest technology to ensure that their baby didn’t carry the BRCA1 fault

40. Beating eye cancer
Retinoblastoma accounts for 11 per cent of all cancers that develop in the first year of life. In almost half of cases, it is caused by an inherited mutation in a gene called RB1. Parents with this defective gene have a 50 per cent chance of passing it on to a child, and it causes tumours in 90 per cent of those who inherit it. The mutation also raises the lifetime risk of suffering other cancers from a third to more than half

41. The eye cancer retinoblastoma, seen above in a young boy, affects about 1 in 15,000 children. About half the cases are hereditary, and those who inherit the defective gene have a 90 per cent chance of developing cancer. Up to 95 per cent of tumours detected early can be treated, but this requires chemotherapy and surgery that can cause blindness.

42. Arguments for creating designer babies
Some couples are not able to have children because their children will have a genetic disease and die before they are born or when they are very young. Techniques used to change the genetic make-up of the embryo allow these parents to have a child.
If we want the best for our children why shouldn't we design our own babies? Using genetic techniques we can help prevent certain genetic diseases. This both saves the children from suffering and reduces the cost and emotional strain of looking after an ill child.
In a few cases where parents have had one child with a serious blood disease, they have used IVF to select embryos so that they can have a second child that can act as a future, tailor-made blood or bone marrow donor.
In these cases when the child is born he or she will be healthy and can help their older brother or sister stay well

43. Arguments against creating designer babies

In these cases, parents and doctors are creating a child to act as an organ-donating factory. The child may feel that they were only born to be a help to their older brother or sister. Children should be loved and cherished for themselves and not what they can do for others.

These genetic techniques are very expensive. Why should only rich people be able to eradicate genetic diseases? This could lead to imbalances between rich and poor people.

We could get carried away 'correcting' perfectly healthy babies. Once we start to eliminate embryos because they have the gene for a disease, what is to stop us from picking babies for their physical or psychological traits

44. Thanks.

1. WORLD ISLANDS
The World or World Islands is an artificial archipelago of various small islands constructed in the rough shape of a world map.It is located 4  kilometeres (2.5 mi) off the coast of  Dubai, United Arab Emirates.

2. The World islands are composed mainly of sand dredged from Dubai's shallow coastal waters, and are one of several artificial island developments in Dubai.

3. The World's developer is Nakheel Properties, and the project was originally conceived by Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai.

4. As of 2010, only a single island has any building on it, which is a show home - all the other projects having been cancelled or delayed due to the 2008 financial crisis.

5. PROJECT:
Islands in the archipelago range from 14,000 to 42,000 square meters (150,000 to 450,000 sq ft) in area.
Distances between islands average 100 meters (330 ft); they are constructed from 321 million cubic meters of sand and 31 million tons of rock.
The entire development is an area that covers 6 by 9 kilometers (3.7 by 5.6 mi) and is surrounded by an oval-shaped breakwater island. Roughly 232 km (144 mi) of shoreline was created.
The World's overall development costs were estimated at $14 billion USD in 2005.

Description:
1. DYNAMIC ARCHITECTURE
Dynamic Tower or Da Vinci Tower, Dubai

2. The tower is expected to be architecturally innovative for several reasons:
Uniquely, each floor will be able to rotate independently.This will result in a constantly changing shape of the tower.Each floor will rotate a maximum of 6 meters (20 ft) per minute, or one full rotation in 90 minutes.

3. DYNAMIC ARCHITECTURE
It will also be the world's first prefabricated skyscraper with 40 factory-built modules for each floor.90% of the tower will be built in a factory and shipped to the construction site.This will allow the entire building to be built in only 22 months.The total construction time will be over 30% less than a normal skyscraper of the same size.The majority of the workers will be in factories, where it will be much safer.The only part of the tower that will be built at the construction site will be the core.The core will serve each floor with a special, patented connection for clean water, based on technology used to refuel airplanes in mid-flight.

4. The entire tower will be powered from wind turbines and solar panels.
Enough surplus electricity should be produced to power five other similar sized buildings in the vicinity.The turbines will be located between each of the rotating floors.They could generate up to 1,200,000 kilowatt-hours of energy. The solar panels will be located on the roof and the top of each floor.

5. In 2008, the designer of the Dynamic Tower said that he expected it to be completed in 2010.Due to the global financial crisis, delays in acquiring land in Dubai, and patent issues, in 2009 Fisher claimed to finish construction late 2011.
However, construction has not started yet, and there has been no official announcement of the building site. Fisher did not "say where the tower would be built, [...] because he wanted to keep it a surprise."

Radiation
Radio active waste
Biological effects
On animals
On plants
On humans
Preventive measures of radiation

3.What is Radiation?
“Invisible energy waves or particles”
What is Radioactivity?
The radioactivity is the property of some atoms to spontaneously give off energy as particles or rays. The atoms that make up the radioactive materials are the source of radiation.

4.Nuclear Pollution and Waste

5.INTRODUCTION
Radioactive waste is a material deemed no longer useful that has been contaminated by or contains radio nuclides.
Radio nuclides are unstable atoms of an element that decay, or disintegrate spontaneously, emitting energy in the form of radiation.
Releases of radio nuclides to the surrounding environment in liquid and gaseous forms.

6.Ionizing and Non-ionizing radiation?
Radiation carries a range of energy forming an electromagnetic spectrum.

Radiation that does not have enough energy to break chemical bonds but can vibrate atom is referred to as “Non-ionizing Radiations” e.g. radio waves, microwaves, infrared, visible light etc.

Radiation that has enough energy to break chemical bonds is referred to as 'ionizing radiation, e.g. alpha particles, beta particles, gamma rays etc.

7.The potential biological effects and damages caused by radiation depend on the conditions of the radiation exposure.

It is determined by:
quality of radiation
quantity of radiation
received dose of radiation
exposure conditions (spatial distribution)
Particles with high energy loss effects cause typically greater damage.

Radiation can cause immediate effects (radiation sickness), but also long term effects which may occur many years (cancer) or several generations later (genetic effects).

Biological effects of radiation result from both direct and indirect action of radiation.

8.Effects on Plants
Green plants are extremely sensitive to gamma rays.
Higher plants have more radio sensitivity than lower plants.
Plants response varies according to age, growth stage, plant species, chromosome volume and level of radiation.
Degree of damage 8 intensity and duration of exposure of radiation.

9.Causes
Changes in morphological, cellular and genetic levels.
Alterations in plant’s vascular system, water transportation and other functions also affected.
More causes are
Retarded growth, decreased percent germination.
Gigantism, dwarfism, curly and misshaped leaves.
Negative effects on Seeds.

10.Radiation gives positive results also..
In crop improvement protocols
High disease resistance, vigor and high productivity.
But high dosage may kill the plants..
It mutate the DNA even in room temperature.
In a food chain, radiation may affect primary and secondary consumers also.

11.Effects on Animals..
It may include tumor, dry, itchy skin, hair loss and discoloration of the skin around the tumor site.
In addition, these particular tumors often release a disagreeable odor as the cancerous cells die.
More serious side effects may include some nerve damage and either the death or hardening (called fibrosis) of healthy tissue.

12.Effects on Humans…
Initial signs include,
Nausea, vomiting, headache , some loss of white blood cells
Doses of 300 rems or more cause temporary hair loss, but also more significant internal harm, including damage to nerve cells and the cells that line the digestive tract.
Besides the symptoms, these people also suffer from fever and diarrhea. If no effective treatment is given, death occurs within two to fourteen days.

13.For survivors, diseases such as leukemia, lung cancer, thyroid cancer, breast cancer, and cancers of other organs can appear due to the radiation received.
But Exposure to ionizing radiation does not necessarily cause cancer

14.Effects on Humans…
Because man's body contains a lot of water, gamma rays traverse through water (H2O) molecules. Ionization of water usually results in the formation of hydrogen peroxide (H2O2). These molecules can attack a bio molecule and 'denature' (= kill) it.
Radioactive lead, retains the ability to cause brain damage and plutonium clumps on the surface of bone, delivering a concentrated dose of alpha radiation to surrounding cells.
It also affects thyroid glands .
It causes the person to have increased pulse rate, nervousness, excitability, loss of body weight and, in females, more frequent c.
If radioactive iodine (I 131 or I 129) is ingested with food it will enter the blood and tend to accumulate in the thyroid.
A small amount of radioactive iodine would probably kill only a few cells and have little or no noticeable effect on health.

15.Preventive measures and considerations
Site selection for nuclear power plants should be carefully made to avoid, or minimize to the extent possible, most of those impacts.
The safe management of radioactive waste is necessary to protect public health.
If handled improperly, potential exposures of humans to high-level radioactive waste can be dangerous, even deadly.

16.Things To follow
Regulation of Radiation Usage
Proper disposal
Minimizing the usage
Wearing protective clothes
Control on these in radiated area..
Inhalation
Absorption
Injection without sterilization

17.Conclusion
For Radiation, like other aspects of nuclear science, can be both destructive and beneficial.
The intelligent use of radiation for the treatment of cancer, medical diagnosis, food preservation, and other useful applications requires an informed public.
Likewise, the solutions to the storage of nuclear waste also necessitate public understanding of the effects of nuclear radiation.

18.Thank You.

PPT On Secrets To Buying Thailand Condominiums

Secrets To Buying Thailand Condominiums

Download

Description:
1.How to buy a condo or apartment in Thailand.
2.One question we are constantly asked is if you have to obtain permission from the government before purchasing property ?
Answer: No
3.To buy a condo or apartment in Thailand is very simple if you're a non-Thai. Most projects have a 51%-49% ownership rule. If the Building is over 51% Thai owned, a foreigner can purchase and own the condo or apartment freehold.
4.If not, you must purchase the apartment as a 30 year lease. Check with the local land office before you purchase if you are unsure about the title deed.
5.Buying direct from the developer has several advantages: you will get to see a range of properties in Thailand that suit your requirements; you have the benefit of many years experience, as well as a English speaking office to support you in your home country; it may help eliminate any possible misunderstandings; and it helps takes away the stress associated with purchasing in Thailand or abroad.
Transactions and payments are simply made by wiring from you home bank account. It's always better to let the Thai banks convert your money in Thailand then to let you home bank to convert it to Baht before you wire. This tip along can save you thousands of dollars when you go to wire a large amount.
Some developers can "lock in" a rate for you before you wire. Make sure you can communicate with your agent by MSN chat, Skype or text message in case you have any last minute questions while at the bank.
The Thai currency system is based on the decimal system. One That Baht is divided into 100 satangs. Coins range in value from ten baht to 25 satangs and six bank notes are in circulation: 10, 20, 50,100,500 and 1000. Always keep lots of small bills as it's a big jump between 100 baht and 500 or a 1000. Most street vendors and taxis can't make change for 1000 baht.
6.Personal effects, household goods and furniture may be imported duty free. There is very high duty on importing a car. I believe with the hassle of dealing with Thai customs it's better to buy what you need inside of Thailand and leave most of your personal effects at home.
7.Find out monthly secrets to Buying in Thailand apartments and properties. Subscribe to our monthly newsletter and get free tips and tricks of the trade. Some tips alone can save you thousands of dollars on your purchase.

PowerPoint Presentation On Climate Change

PPT On Climate Change

Download

Description:
1.IMPACTS OF CLIMATE CHANGE ON LIVESTOCK AND MITIGATION STRATEGIES

2. Climate
Specific atmospheric trend and pattern of particular place determined by the interaction of Atmospheric elements

3. Climate Change
Climate change is a phenomenon due to emissions of greenhouse gases from fuel combustion, deforestation, urbanization and industrialization (Upreti, 1999) resulting variations in solar energy, temperature and precipitation.

4.Livestock : GHG emissions
Livestock  18 % of GHGs
The enteric fermentation of animals,
Manure (waste products),
Production of feed and forage (Dourmad et al., 2008).
Indirect sources : changes in land use and deforestation to create pasture land.

5.Climate change will have major impact on the people who depend on livestock for their livelihoods (Thornton et al., 2002).

6. Climate Change and its Impacts in Nepal
Approximately 0.06 degrees Celsius per year.
Temperature in the Himalayas is increasing at a faster rate.
The Rika Samba Glacier in the Dhaulagiri region is retreating at a rate of 10m per year.
The AX010 Glacier of Shorong Himal will be extinct by 2060 if the current trend continues.
More than 40 Himalayan glacial lakes are dangerously closed to bursting (UNEP).
Rapidly melting glaciers means more seasonal variation in river flow water shortage, frequent floods and draughts in the country.

7.Direct And Indirect Impacts On Livestock And Livestock Systems
Feeds: quantity and quality
Herbage growth and quality
Changes in composition of pasture
Changing concentration
of water soluble carbohydrates
and N at given dry matter yields
Lignifications of plant tissues

8.B. Heat stress :
Feed intake, mortality, growth, reproduction, maintenance and production
Increased energy deficits

C. Water :
Water scarcity
Not only will affect livestock drinking water sources, but it will also have a bearing on livestock feed production systems and pasture yield (Thornton et al., 2008)

9.D. Livestock diseases and disease vectors
Vector-borne diseases could be affected by:
(i) Expansion of vector populations into more temperate zones (such as livestock tick-borne diseases in higher altitude areas).
(ii) Changes in rainfall pattern during wetter years, which could also lead to expanding vector populations and large-scale outbreaks of disease.

10.Livestock disease
Helminthes infections.
Trypanotolerance- could be lost.
Distribution and impact of malaria in many systems.
Schistosomiasis and lymphatic filariasis in irrigated systems.
Heat-related mortality and morbidity could increase (Thornton et al., 2008).

11.E. Biodiversity
A 2.5° C rise in global temperature
high risk of extinction.
Local and rare breeds could be lost

12.Livestock Adaptation strategies
Breeding strategies
Identifying and strengthening local breeds
Adapted to local climatic stress and feed sources
Heat tolerant breeds
Disease tolerant breeds
Improving local genetics
Cross-breeding

13.Livestock management systems
Shade and water to reduce heat stress.
Reduction of livestock numbers – a lower number of more productive animals leads to more efficient production and lower GHG emissions from livestock production (Batima, 2007).
Changes in herd composition (selection of large animals rather than small)
Improved management of water resources (e.g. drip and sprinkler irrigation, store rainwater).

14.Mitigation of livestock GHG emissions
Higher concentrate in the diet  lower the emission of CH4.
Management of animal waste products (covered storage facilities).
Pasture grazing through rotational grazing.
Management of feed crop production.
Selection of faster growing breeds.
Lowering livestock production and consumption

15.Take-home messages
Participatory approaches to sustainable management of natural resources
Community involvement in adaptation strategies
Financial incentives
Risk management mechanisms
Awareness and education
Mitigation strategies
Innovation, research and technology development
Indigenous knowledge
