Abstract: 

Deployable structures are a novel and unique type of engineering structures, which can be packaged for transportation and expanded automatically at the time and site of operation, and in some cases, can be retracted for re-use or other purposes. They retain the functionality of conventional structures and in addition, can undergo large geometric transformations. They are light-weight and very compact when folded. A few deployable structures are in very common use in almost every household umbrellas, folding chairs and tents; however proper research into deployable structures started only three decades ago. In this sense, it is relatively young subject in the long history of structural engineering. Space exploration critically depends on deployable structures, which make possible satellite communication and other space systems. The largest payload volume currently available, provided by NASA, reaches a diameter of 4.6 m and a length of 18.3 m; present and future space structures are more demanding in their volume requirements. Obviously, such structures cannot be delivered into space in their service geometry because launching vehicles are limited in their size. The limitation in payload volumes has urged the widespread use of deployable structures and presents considerable challenge and exciting opportunities for imaginative concepts and ideas. Of interest: The Cambridge University Deployable Structures Laboratory.

Abstract: 

In this talk we shall discuss the structure and dynamics of the plasma environment of the earth and how it is influenced by the sun and its magnetic field, as has been revealed to us by observations, both remote and in situ, in the past 40 years or so. After presenting a brief overview of the major historical landmarks in the development of space plasma physics, we shall discuss the structure of the solar plasma and then see, by looking at its interaction with the earth�s magnetic field, how the earth�s magnetosphere and ionosphere are. We shall look into the composition of the earth�s plasma layers. We shall also briefly discuss the behaviour of comets when they come close to the sun.

Genetic Therapy

Abstract: 

Advent of Recombinant DNA Technology has made it possible to detect defective genes and replace them with "good" genes. Consequently the genetic diseases, which result on mutations can now be cured. The first successful gene therapy experient was done on a 9 year old Indian girl Ashanti in 1990 in USA, who was suffering from a fatal immunological disease - SCID, which is caused by a mutation in ADA gene. The scientists introduced the the "good" copy of the gene in her body and were successful in curing her of this fatal disease. This encouraged other researchers and now several methods are being tried to cure genetic diseases. The 21st Century is the era of Gene therapy and keeping in view tremendous advancements made in the Recombinant DNA technology, it is expected that cure for several genetic defects would be available within the next decade.

Some Expert Comments:

  • The detection of defective genes and their replacement works quite well in vitro, but not in-vivo.
  • There are no cures to genetic disorders based on mutations. I assure you this is incorrect; there has not been a single case of gene therapy curing a genetic disorder. Efforts to transduce normal copies of genes into patients with genetic disorders have been successful to varying degrees, but no cures yet.
  • In Ashanta's story, there was no cure - simply incorrect. It was nonetheless a hallmark in biomedical research; it hinted at the promise gene therapy held.
  • As far as the claim that genetic therapy may cure several disorders in the next decade, only time will tell. I would not venture to be so prophetic. A few years ago Harold Varmus, then director of the National Institutes of Health, assembled a panel of experts to assess the status of the field of gene therapy. You see, for quite some time many in the field had been feeling that gene therapy was being pushed to the patient's bed prematurely. The panel's conclusion was right on the mark: the field needs much more research at the fundamental levels, such as development of safe, efficient, and specific gene delivery vectors.

Abstract: 

The focus of this presentation will be the application of Non linear sciences to practical engineering and technological problems. Traditional "linear" sciences (that we all study in universities and colleges and schools) fail to provide answers to most of our questions because God made the world Nonlinear. It has been hailed as the science of the 21st century and a revolution in scientific method. Though, till now, most of the work in nonlinear sciences has been done by theorists in laying the foundations of its different aspects, the past few years have witnessed the increasing interest of technologists and engineers in applying it to practical real life problems. Digital communications, stunning computer graphics, data compression, stock market prediction and controlling heart attacks are a very ill-represented part of a wide spectrum of applications that cover all major areas of technology. We will see the different aspects of nonlinear theory such as chaos theory, complex adaptive systems, fractal geometry and how they interpret each other. The speaker will emphasize the utililty of these new tools in understanding very complicated phenomenon; from circuits and quanta to wars and living cells. Finally he will give a brief overview of his work regarding use of chaotic dynamics to send secret messages. The scope of the presentation will be very general and i will avoid use of any equations to explain ideas. The object of this presentation would be to motivate people rather than bombarding them with equations. Any student of engineering, sciences, economics, medicine or social sciences should be able to follow. People from all disciplines are welcome.

Abstract: 

1. Applications of Interfacing Nowadays, every complex manipulation of data is accomplished on a computer. A computer can handle extraordinary amounts of data. In the industry and in labwork, there is always a large amount of data to be handled and processes. The conventional way is to note the data from devices, such as the control and instrumentation panel, enter it manually in the computer and then process it. Computer interfacing has solved the problem of data acquisition. Now, the computer not only automatically acquires the data from the external hardware but is also programmed in a special way to send data to control the same devices. These devices are controlled to fulfil the machinery and production line needs.

 

Below are a few examples where computer interfacing can be used: 1. Monitor the speed of a motor and adjust it according to the requirements. 2. To monitor environmental parameters such as temperature and pressure and to keep these parameters constant or within tolerable limits. For example, cooling fans may be turned on when the temperature exceeds a certain value. 3. To turn on a machinery for a certain period of time. 4. In instrumentation, computers can replace oscilloscopes, multimeters and any measurement instrument imaginable.

Once we make an appropriate circuit and interface it with he computer, then each action is just a mouse click away.
