Advances in Cold-Region Thermal Engineering and Sciences: Technological, Environmental, and Climatological Impact Proceedings of the 6th International … 22-25 August 1999

Product Description
This book consists of peer-reviewed articles and reviews presented as lectures at the Sixth International Symposium on Thermal Engineering and Sciences for Cold Regions in Darmstadt, Germany. It adresses all relevant aspects of thermal physics and engineering in cold regions, such as the Arctic regions. These environments present many unique freezing and melting phenomena and the relevant heat and mass transfer processes are of basic importance with respect to both the technological applications and the natural context in which they occur. Adressing physicists, engineers, geoscientists, climatologists and cryologists alike these proceedings cover topics such as: ice formation and decay heat conduction with phase change – convection with freezing and melting – thermal properties at low temperature – frost heave and permafrost – climate impact in cold regions thermal design of structures – bio-engineering in cold regions – and many more …

Nanopathology: The Health Impact of Nanoparticles

Product Description
Enormous funds are currently being invested in nanotechnology, yet very little is known about how its products and by-products can interfere with organisms, both end-users and people involved in their manufacture. Similar scenarios are already widely known in the history of science, such as the exploitation of radioactivity or the controversial issue of genetically modified organisms. As nanoparticles are more or less voluntarily produced, they are almost uncontrollably disseminated in the environment and in organisms, and thus constitute a growing concern. Describing the impact of nanoparticles (and microparticles) on human and animal health, this book offers the first criteria for preventing potential problems deriving from these particles.

Contents: How the Whole Thing Began or the Logic Path Towards a Discovery; In-Vitro and In-Vivo Biological Behavior of Micro and Nanoparticles; Clinical Cases: Lung, Blood, Liver, Kidney, Digestive System, Vessels, Sperm; Six Detective Stories ; War and Nanoparticles; Nanoparticles in the Environment and Working Places; Nanoparticles in Food, Cosmetics and Other Products; New York 9/11; The Future and Prevention Criteria.

Analyzing the Impact of Product Evolution

Emergence of the new technological solutions such as software, microchips, bioengineering, nanotechnology resulted in higher emphasis being placed on pharmaceuticals, ICTs, and other high tech industries. At the same time, low tech sectors have also greatly evolved over time. For instance, the Portuguese footwear industry has gone through restructuring process in the 1990s: creative use of micro electronics has been introduced. As a result of this innovation, industry managed to expand despite the raising labor costs. Bioengineering is being widely used in the wine industry through fermentation techniques that enhance quality of wine. Bacteria biotechnology renewed the classic cork technology used traditionally for centuries.

In all of these cases, industry had to adjust to the new technological solutions. Companies that employed new approaches successfully retained and increased their market share, whereas traditional companies have been forced out of business. It should be pointed out that the restructuring process had significant impact on company organizational and business strategies that had to be adjusted accordingly.

Undoubtedly, Schumpeterian theory had a great impact on the current business strategies. The major lesson to be learned by the companies in business is that innovation can be transferred into a sustainable competitive advantage that cannot be easily followed by other competitors in the industry. As such, businesses must remain open minded and develop adaptive capabilities. The theory of “Peter” still remains the milestone of business practices, as the essentials for gaining and treating innovation remain unchanged – business must gain knowledge to create and sustain competitive advantage.

Learning organization – is the direct implication of the Schumpeterian’s “gales of creative destruction”. People in a learning organization must continually expand their capacity to create the results they aim at. Only under this condition organizations are able to adjust to the situations of rapid change: flexibility and productivity. There are five basic steps that distinguish learning organization from the traditional ones: personal mastery, systems thinking, mental model, building shared vision, and team learning. Combined implementation of these five basic steps allows companies to respond to the emerging changes in business environment and turn innovation into a competitive advantage.

Innovation is a continuous process that cannot be controlled or predicted with a certain degree of verifiability. In order for organizations to survive in the dynamic 21st century, they must remain flexible and enhance learning at all stages. Learning organization is the key to a strong position in the dynamic market place.

Tiny Inventions Impact our Lives in Big Ways

Among the latest scientific inventions of great importance to us in our daily lives are devices known as MEMS.  Microelectromechanical systems (MEMS) are the technology of the very small. In Japan MEMS are also called micromachines. Smaller still, are the nano-scale nanoelectromechanical systems (NEMS) and nanotechnology.

MEMS are made up of components between 1 to 100 micrometers in size (i.e. 0.001 to 0.1 mm) and MEMS devices generally range in size from 20 micrometers (20 millionths of a meter) to a millimeter.  MEMS became practical once they could be fabricated using modified semiconductor fabrication technologies, normally used to make electronics.

One type of invention impacting our lives is the accelerometer. An accelerometer measures the acceleration and gravity it experiences. Modern accelerometers are often small micro electro-mechanical systems (MEMS), and are indeed the simplest MEMS devices possible, consisting of little more than a cantilever beam with a proof mass. Under the influence of gravity or acceleration the proof mass deflects from its neutral position. This deflection is measured in an analog or digital manner. This method is simple and reliable; it also does not require additional process steps making it inexpensive.

Micromechanical accelerometers are available in a wide variety of measuring ranges, reaching up to thousands of g’s. These amazing little devices are what allow us to take for granted the most commonplace things in our lives, while benefiting from them immensely.

 For instance, these latest of scientific devices tell our air bags when to deploy.  Do you feel that we benefit from our airbag technology?   They are becoming endemic in gaming devices and even iPhones and other smart phones are using them for interfacing purposes.  They are being incorporated into laptop computers to sense screen orientation, and to park hard drive heads in case a drop is detected.  They are also used for images stabilization in digital cameras and a host of other applications. They are everywhere you look these days.

Another area where MEMS are popping up is in pressure sensors. MEMS technology combines microelectronics with tiny mechanical systems such as valves, gears, and other mechanical components all on one semiconductor chip using nanotechnology to measure pressure. Pressure sensors can be used for directly sensing pressure for such uses as measuring weather data, aircraft performance parameters, automobiles processes, medical devices, and other machine applications . 

These latest scientific inventions can be used for sensing altitude for use in aircraft, rockets, satellites, weather balloons etc. And finally, they can be use for flow sensing. MEMS technology is responsible for everything from automatic blood pressure monitoring devices to monitoring tire pressure of your car.

I’ve barely touched upon the latest scientific inventions in the MEMS field, just think of the military and battlefield uses for such a technology, research is underway for such things as smart clothing and smart armor.

We are using these technologies in the exploration of the ocean depths by implanting them into whales and fish, and monitoring them with radio technology.  All fields of science will continue to benefit from the amazing new inventions being spawned by these amazing and cool new technologies.
