The term Globalization has been quite influencive in many sectors, particularly in job sector. Globalization is a difficult phenomenon to explain properly. Science and technology has quite importance in every aspect of life, but particularly the way in which technology is globally integrating the peoples of the world. The word globalization can be heard quite oftenly in political and economic dialogue. This term has brought new opportunities. The life span for the technical skills is getting shorter and shorter, when it comes to the knowledge based society. And for that purpose, the technical professionals should be up to date as far as globalization trends are concern. education is rapidly evolving as the pace of technological innovation in society accelerates. It is because excellent technical skills are required by complex and innovative global environment. For global market, knowledge and teamwork skills are essentials.
The world population has topped to 6 billion people and is predicted to double in the next 50 years. Ensuring an adequate food supply for this booming population is and will continue to be a major challenge in the years to come. Genetically Engineered foods promise to meet the difficult task of providing an adequate food supply and aid in the prevention of starvation. Biotech crops posses the following traits that prove them to be superior to conventional crops; pest resistance, herbicide tolerance, disease resistance, and drought tolerance. Genetically Engineered foods will produce faster, healthier, and economically efficient crops.
1.Safety systems are necessary for all military aircraft which are designed to operate on the fringes of safety envelope and are inherently vulnerable to internal or externally induced failures. The safety systems while ensuring safety of the aircraft and/ or aircrew, do not directly contribute towards operational capability of the aircraft. Their addition into the aircraft thus imposes a weight penalty and it is a challenging task for the designer to minimize their weights. It is in the use of fabrics for safety systems that the Russian and western design approaches converge. Fabrics are now universally and extensively used in the design of safety systems of military aircraft due to their light weight and a host of other favorable properties. Important examples are parachutes, dinghies, life jackets, survival packs, arrester barrier nets etc.
INTRODUCTION: Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. The Earth receives 174 petawatts (PW) of incoming solar radiation at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, day lighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes. To harvest the solar energy, the most common way is to use solar panels which are oriented in a specific direction.
CONSUMER VS E-WASTE : WHO’S GOING TO RUN THE SHOW This paper has been jointly authored by S SURESH KUMAR, a post graduate in computer science, and a research scholar employed with GoI alongwith Dr SP VICTOR Head of Department & Director of Research Centre at St Xaviers College , Palayamkottai Tirunelveli both of whom instill great concern for nature.
Orbital Space Debris The sun rose blindingly over the crest of the earth. The astronaut moved outside the Space Shuttle Discovery’s cargo bay in his Manned Maneuvering Unit (MMU). Held by the shuttle’s robotic arm, a damaged satellite hung about 800 kilometers above the earth and a few meters below the astronaut. As the space walker hovered closer to the satellite, he looked down to see clouds covering parts of America, including his home state of Nebraska. The satellite was damaged badly. Sporting only one solar panel, it had a broken metal arm that made merely a stub on the other side. The day earlier, they had intercepted the missing solar panel, burned and smashed beyond repair. Upon inspection of the damages, both in space and back on earth where the satellite was taken, it was confirmed that a small piece of foreign space debris was responsible for knocking out this civilian communications satellite. While in the vastness of space, an accident like this seems only realistic in a Hollywood movie, but this fictional description is more real than what people realize. It has been fifty years since the launch of the first satellite, Russia’s Sputnik. Since then, as is the case with rapidly advancing technology, satellites have only proliferated and become more entrenched in society’s existence. This has created an incredible amount of crowding in the earth’s orbit that will only get worse as time progresses.
Automation plays an increasingly important role in the global economy and in daily experience. Engineers strive to combine automated devices with mathematical and organizational tools to create complex systems for a rapidly expanding range of applications and human activities. Many roles for humans in industrial processes presently lie beyond the scope of automation. The problems related to automation system failure are discussed in this paper. Different features for building good automation systems are also highlighted in this paper.
The idea of molecular manufacturing is based on the concept of scaling which is hence required to be deeply studied the various concepts for nano based manufacturing have been developed or proposed as a hypothesis. The main concepts with which we deal in this paper are the basic concept of nanotechnology and further the idea of making a basic nano factory, the problem faced due to scaling and various methods and assumptions that can lead to the formation of a feasible nano factory. The performance of advanced products, and some likely applications, are discussed. Finally, considerations and recommendations for a targeted development program are presented.
Through different interviews I have conducted, the conclusion that I have came up with is; the average person thinks that an engineer just designs buildings. There are many more things that engineers design. There are nine different disciplines within the engineering realm that work on other forms of engineering aside from designing buildings. The engineering field has many jobs within it that create and produce products that we see and use from day to day. Engineers of today are moving our society into the future and make our lives easier by creating useful products that help improve our way of life.
Abstract Based on findings by Oliveira et al (2007) and Kondamudi et al (2008 ), this paper aims to outline the socio-economic and environmental benefits of producing biofuels from the waste products of the coffee industry. On average, a fifth of all coffee grown in Latin America is defective, (Oliveira et al 2007) and cannot be sold on international markets where very high standards of quality are required. Using this defective coffee for fuel instead of for the production of low quality beverages would be beneficial to the small scale producers of coffee, as the defective beans may command a much higher price if sold to the biodiesel industry. Additionally, the main hindrance to biofuel production is the cost of crop production. By making use of the wasted by-product of the existing industry, both the economical, and environmental costs of biodiesel production could be reduced.
