PROTEIN-DRUG BINDING & ITS SIGNIFICANCE 2007 2 1 147 KB

For A drug moiety there are several tissue components comprising of blood and extravascular tissues available in the body for biological interactions to take place. The molecules indulged in such biological or physiological interactions are said to be macromolecules as they are large in structures and quite complex depending upon the type involved. These macromolecules are proteins, DNA, adipose tissues etc. thus the protein binding process is defined as a phenomenon of complex formation following the interaction of drug moiety and the protein molecule.The significance of protein binding of drugs is that - As a protein bound drug is neither metabolized nor excreted hence it is pharmacologically inactive due to its pharmacokinetic and Pharmacodynamic inertness. A bound drug always remains confined to a specific tissue or to a particular site with which it possess a greater affinity. The major benefit is the prolonged duration of action of drug as the protein bound-enormous size of drug complex cannot undergo membrane transport....

DIGITAL DRUGS 2007 2 1 147 KB

We have always dreamed of robots who work for us and respect the orders we give to them. In the embryonic stage of the robotic era, the commands were given to them by the means of programs embedded in the chip. Now , for some robots commands are given by the means of speech and are converted to the machine language using some software , which the robot can execute. But just think about the time when the commands would be given by the means of thought only !! It would mean that to get a job done by an robot , you just need to think about it and the job gets done.....

Introduction to Oncogenes and Tumor Suppressor Genes 2007 2 2 70 KB

All living things are made of cells. Cells work together to form organs. Each cell has a control center called a nucleus. The nucleus contains the information that tells the cell what to do and when to grow and divide. This information is contained in genes, which are the building blocks of chromosomes. In the nucleus of each human cell (except for sperm and egg cells), there are 23 pairs of chromosomes. Chromosomes are made up of long strands of a substance called DNA (deoxyribonucleic acid), which is a collection of molecules called bases arranged in a certain sequence. Within each chromosome, there are many hundreds to thousands of genes. Genes are segments of DNA that tell the cell to do a specific task, usually to make a particular protein. Each protein has a specific job or function in the body. Each human cell has about 30,000 genes; each one makes a protein with a unique function. A cell uses its genes selectively – that is, it will activate, or "turn on" the genes it needs at the right moment. Some genes stay active all the time to produce proteins needed for basic cell functions. Others shut down when their job is finished and start again later if needed. ...[Read details]

Tumor Immunotherapy 2007 2 5 70 KB

As it applies to cancer, immunotherapy might be considered a revolutionary form of medicine but its roots actually go back as far as 1778, when Edward Jenner, an English physician, administered the first vaccine, which was targeted against smallpox.Tumor immunotherapy is an anticancer approach in which the patient’s immune system is either prodded or cajoled to fight tumors. Over time, our understanding of the immune system and tumor immunology has increased and this has enabled scientists to develop the ability to apply specific immunotherapies designed to enhance the immune response of a particular patient against unique targets....[Read details]

STUDY OF SPANNING TREE PROTOCOLS 2007 2 1 155 KB

We report in this paper our study of Spanning Tree Protocols. Spanning Tree protocols are link management protocols that provide path redundancy while preventing undesirable loops in the network. For an Ethernet network to function properly, only one active path can exist between two stations.Multiple active paths between stations cause loops in the network. If a loop exists in the network topology, the potential exists for duplication of messages. When loops occur,some switches see stations appear on both sides of the switch. This condition confuses the forwarding algorithm and allows duplicate frames to be forwarded.To incorporate the required feature of Redundancy and at the same time to avoid broadcasting storms from congesting the network, spanning tree protocols are used.IEEE is one of the most widely recognized standarazation bodies in computer science.IEEE 802 refers to a family of IEEE standards about local area networks and metropolitan area networks.One of its standard is IEEE 802.1, standard for MAC layer & Internetworking Devices. In this report we report our study of the 802.1d (STP),802.1w (RSTP) & 802.1s (MSTP) which are Spanning tree protocols implemented in Routers and Switches....

Machine Recognition of Human Face 2007 2 2 172 KB

Machine recognition of human face is an active and fast growing area of research due to a wide variety of commercial and law-enforcement applications including access control, security monitoring, and video surveillance. The major advantage of this biometric approach is its ability for authentic identification of a person’s identity. While the established and widely used authentication criteria such as passwords, PINs (Personal Identification Numbers) or magnetic cards suffer from the risk of getting stolen, copied, lost and are thus exposed to fraudulent use biometric approaches are expected to be immune from this drawback. Among the various biometric approaches, face recognition offers the additional advantage in that this approach allows a passive and non-intrusive identification in a user-friendly way without having to interrupt user activity. We provide, in this report, a brief overview of the techniques being explored for developing a face recognition system and indicate the present state-of-the-art of the field....

STUDY OF SPANNING TREE PROTOCOLS 2007 2 3 118 KB

Spanning-Tree Protocol (STP) as defined in the IEEE 802.1D is a link management protocol that provides path redundancy while preventing undesirable loops in the network. For an Ethernet network to function properly, only one active path can exist between two stations. STP is a technology that allows bridges to communicate with each other to discover physical loops in the network. The protocol then specifies an algorithm that bridges can use to create a loop-free logical topology. In other words, STP creates a tree structure of loop-free leaves and branches that spans the entire Layer 2 network. Bridge Protocol Data Units (BPDUs) is used by bridges in a network to exchange information regarding their status. The Spanning-Tree Protocol uses the BPDU information to elect the root switch and root port for the switched network, as well as the root port and designated port for each switched segment....

Cell Phone Cloning 2007 2 4 96 KB

You might have read news of the cloning of sheep or cattle with amused interest. But how would you feel if somebody `cloned' your mobile phone? Technology is finally rearing up its dark side. Along with the proliferation of technological innovations, this era also marks the birth of the new-age IT criminals in a big way, with the latest technology fraud being cell phone cloning.Cell phone cloning is a technique wherein security data from one cell phone is transferred into another phone. The other cell phone becomes the exact replica of the original cell phone like a clone. As a result, while calls can be made from both phones, only the original is billed.Though communication channels are equipped with security algorithms, yet cloners get away with the help of loop holes in systems. So when one gets huge bills, the chances are that the phone is being cloned....

REMOTE SENSING AND ITS APPLICATION 2007 2 6 144 KB

The “Remote Sensing” technique proves itself as a boom in an economic development all over. This technical paper briefly deals with application and result of remote sensing techniques and its types. As we know that “Remote Sensing” is the science and art of acquiring information (spectral, spatial, temporal) about material objects, area, or phenomenon, without coming into physical contact with the objects, or area, or phenomenon under investigation. Without direct contact, some means of transferring information through space must be utilized. In remote sensing, information transfer is accomplished by use of electromagnetic radiation (EMR). EMR is considered to span the spectrum of wavelengths from 10-10 mm to cosmic rays up to 1010 mm, the broadcast wavelengths, which extend from 0.30-15 mm. Targets in remote sensing images may be any feature, which can be observed in an image, and have the point, line, or area feature. But the target must be distinguishable i.e. it must contrast with other features around it in the image. Remote sensing images can also be represented in a computer as arrays of pixels, with each pixel corresponding to a digital number, representing the brightness level of that pixel in the image....[Read details]

Mobile Ad-Hoc Network (MANET) 2007 2 4 97 KB
Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently.To accommodate the changing topology special routing algorithms are needed. For relatively small networks flat routing protocols may be sufficient. However, in larger networks either hierarchical or geographic routing protocols are needed. There is no single protocol that fits all networks perfectly. The protocols have to be chosen according to network characteristics, such as density, size and the mobility of the nodes. MANET does not require any fixed infrastructure, such as a base station, therefore, it is an attractive option for connecting devices quickly and spontaneous....

SOLITONS IN FIBER OPTICS 2007 2 5 88 KB

Solitons are Solitary waves and can be generated in dissipative nonlinear media with group velocity dispersion (GVD) and periodical amplification. Its preservation in such media can be explained on the one hand by the presence of a strong balance between the group velocity dispersion and nonlinearity and, on the other, with the presence of the delicate balance between losses and nonlinear amplification. The term "Soliton" was introduced in the 1960's, but the scientific research of Solitons had started in the 19th century when John Scott-Russell observed a large solitary wave in a canal near Edinburgh. More formal definitions exist, but they require substantial mathematics. The stability of Solitons stems from the delicate balance of "nonlinearity" and "dispersion" in the model equations. Nonlinearity drives a solitary wave to concentrate further; dispersion is the effect to spread such a localized wave. If one of these two competing effects is lost, Solitons become unstable and, eventually, cease to exist. In this respect, Solitons are completely different from "linear waves" like sinusoidal waves...[Read details]

TECHNICAL PAPER ON SOLENOID 2007 2 6 266 KB
Solenoids are actuators capable of linear motion. They can be electromechanical (AC/DC), hydraulic, or pneumatic driven - all operating on the same basic principles. Give it energy and it will produce a linear force. They are great for pushing buttons, hitting keys on a piano, valve operators, and even for jumping robots. Depending on the field of application of a solenoid, different amount of displacement (linear motion) is required. However there is a limitation to the amount of linear motion obtained by a solenoid. When a solenoid is designed to provide large linear motion then the amount of force produced by that motion decreases. So depending on the requirement, a solenoid is designed to offer optimal values of force and linear motion. The solenoids commonly available in the market can provide a maximum of 25-30 mm linear motion. This paper deals with the design of an electromechanical solenoid, which will increase its movement even up to 50 mm. Various applications and basic functioning of solenoids will also be discussed....

Network Security 2007 2 6 58 KB
Network security is a complicated subject, historically only tackled by well-trained and experienced experts. We have heard this word uttered with great conviction many times. However, the first time it causes any inconvenience to system owners, administrators, or users, the same people hasten to add “except when it impacts performance, system complexity, or cost”. Let's face it. Security is usually discarded when it contends with performance. The reason is simple, and at one time it may have even been valid: performance directly contributes to the bottom line while security provides only indirect benefits. But as the world becomes more tightly interconnected, organizations are feeling a greater need to rediscover network security. A thread that spans most definitions of network security is the intent to consider the security of the network as a whole, rather than as an endpoint issue. A comprehensive network security plan must encompass all the elements that make up the network and provide five important services:-...

Trojan Horse 2007 2 6 89 KB
The Trojan Horse got its name from the old mythical story about how the Greeks gave their enemy a huge wooden horse as a gift during the war. The enemy accepted this gift and they brought it into their kingdom, and during the night, Greek soldiers crept out of the horse and attacked the city, belly and open the city gates, allowing their compatriots to pour in and capture Troy....

WIRELESS TECHNOLOGY 2007 2 1 58 KB

The term wireless is normally used to refer to any type of electrical or electronic operation which is accomplished without the use of a "hard wired" connection. Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires”. The distances involved may be short (a few meters as in television remote control) or very long (thousands or even millions of kilometers for radio communications). Wireless communications is generally considered to be a branch of telecommunications....

Self-Compacting Concrete 2007 2 2 537 KB

For several years beginning in 1983, the problem of the durability of concrete structures was a major topic of interest in Japan. The creation of durable concrete structures requires adequate compaction by skilled workers. However, the gradual reduction in the number of skilled workers in Japan's construction industry has led to a similar reduction in the quality of construction work. One solution for the achievement of durable concrete structures independent of the quality of construction work is the employment of self-compacting concrete, which can be compacted into every corner of a formwork, purely by means of its own weight and without the need for vibrating compaction (Fig. 1). The necessity of this type of concrete was proposed by Okamura in 1986. Studies to develop self-compacting concrete, including a fundamental study on the workability of concrete, have been carried out by Ozawa and Maekawa at the University of Tokyo. The prototype of self-compacting concrete was first completed in 1988 using materials already on the market (Fig. 2). The prototype performed satisfactorily with regard to drying and hardening shrinkage, heat of hydration, denseness after hardening, and other properties. This concrete was named “High Performance Concrete” and was defined as follows at the three stages of concrete:...[Read details]

Concrete Recycling 2007 2 3 532 KB

While at present mostly recycled into road subbase, the amount of demolished concrete in Japan is expected to increase rapidly and exceed the demand for road subbase in the near future. To promote the recycling of concrete, a technology to produce high-quality recycled aggregate has been developed. This technology employs the heating and rubbing method. In order to investigate a future concrete recycling system, first of all, a specific model considering indices of economic activity is established to forecast the amount of demolished concrete in the future....[Read details]

Network Alignment Tools for Novel Insight in Cellular Machinery 2007 2 1 147 KB

Molecular networks represent the backbone of cellular activity within the cell. Research has revealed that protein–protein interaction (PPI) networks evolve at a modular level having scale free topology. As the amount of available data on these networks increases, discovery of conserved patterns in these networks becomes an important problem. Recent studies have taken a comparative approach toward interpreting these networks, contrasting networks of different species and molecular types, and under varying conditions. Many of the methodological and conceptual advances that were important for sequence comparison will likely also be important at the network level, including improved search algorithms, techniques for multiple alignment and better integration with public databases. In this review, we survey the field of comparative biological network analysis and describe its applications to elucidate cellular machinery and to predict protein function and interaction.

Content-Based Web Filtering and Blocking 2007 2 1 147 KB

To an organisation, centralized Internet filtering and blocking is very important for a couple of reasons. With the flooding of pornographic materials on the Web, educators and parents would like to block these offensive materials from their children. Companies also want to reduce the amount of work time that its employees spend on non-productive Web surfing. Current blocking and filtering mechanisms can roughly be classified into two approaches: URL based and content filtering. In the URL based approach, a requested URL address will be blocked if a match is found in the blocked list. However, keeping the list up-to-date is very difficult. New sites are kept uploading onto the Internet daily; many blocked sites try to use multiple IPs and domain names; the sites might also be moved regularly. In the content filtering approach, keyword matching is often used. Its main problem is the mis-blocking. Many desirable Web sites are blocked because some predefined keywords appear in their Web pages, though in different meaning or context. There are even suggestions for image, audio, and video understanding in real-time content filtering. Of course, the delay time as well as the mis-match between the HTTP streaming protocol and the complexity of the filtering algorithm will be of great concern. In this paper, we investigate how far the multimedia content analysis should go for Internet filtering and blocking. A set of guidelines for defining the heuristics used in the real-time Web content analysis is also given. These heuristics not only have higher filtering accuracy than most multimedia retrieval techniques do, but they also have comparable runtime overhead as the keyword matching does.

Web vision and the blind world 2007 2 1 147 KB

Visual dominated technology is making visually impaired people more vulnerable and disabled. The Web has shown the potential to be part of a structure-based world that would solve many of the problems of information provision in non-visual forms.Until now, visually impaired users have been the primary consumers of spoken access to computing applications. Speech access to computing applications has been typically provided by developing generic screen-reading applications --programs that build a model of the visual display and then present this model using speech. This technique has been fairly effective in retrofitting speech output to applications that were developed with no thought to their use in an eyes-free environment by a functionally Blind user.Today, a moderate degree of spoken access to the Web can be provided by using screen-reading applications on standard computing platforms like Windows98 in conjunction with popular Web browsers like Netscape Navigator or Internet Explorer. Other users needing speech access and vary of using a GUI relies on terminal based browsers like LINUX.The inherent shortcoming in the screen-reading approach is that the spoken output is decoupled from the application being used. Most screen-reading applications available today are completely defeated by the use of tables in HTML to achieve specific visual layouts such as multicolumn documents.The problems described above arise primarily due to the screen-reading approach only examining the final form appearance of the document as rendered by the visual browser.In suggested software techniques are implemented for a fully speech-enabled audio desktop. The remaining sections of this paper focus on one aspect of this environment, namely the speech enabled browser.The speech-enabled WWW browser available on the suggested software's platform produces succinct context-specific spoken feedback by examining the logical structure of the document rather than its visual appearance on the screen. By tightly integrating the speech system with the WWW browser, the environment provides fluent spoken interfaces to interactive document elements such as fill out forms. Finally, it should be pointed out that speech-enabled WWW browsers like the one described here rely implicitly on well marked up HTML documents, where the document logical structure is clearly separated from the visual presentation.

SECURITY GLITCHES IN SOCIAL NETWORKING SITES 2007 2 1 147 KB

The Social Networking Sites or SNSs are creating a means for hackers and conmen to worm their way into the confidence of users. The social networking sites have been till now been hit by mostly worm, adware, spyware and phishing attacks but now they face a greater danger of being hit by more severe attacks, such SQL injection, denial of service, cross-site scripting etc. Although the indivisual users are less susceptible and more immune to these malicious attacks by hackers than organizations, however attacks on indivisual systems are also being made in a fairly big way. This paper aims to examine the various important attacks that are made by hackers on the SNSs,the holes existing in such social networking websites and make recommendations about the best practices for reducing security risks.
