Silicon-on-insulator (SOI) wafers are precisely engineered multilayer semiconductor/dielectric structures that provide new functionality for advanced Si devices. It also improves prospects for extending Si devices into the nanometer region (<10 nm channel length). SOI technology possesses many advantages over bulk silicon technology such as reduction of parasitic capacitance, excellent sub-threshold slope, elimination of latch up and resistance to radiation. Hence it is preferred for high speed, high -temperature and low power microelectronic devices. An SOI microchip processing speed is often 30% faster than today's complementary metal-oxide semiconductor (CMOS)-based chips and power consumption is reduced 80%, which makes them suitable for mobile devices.

An experimental study of natural convection heat transfer in vertical annular cylinders embedded with porous medium at constant wall temperature has been undertaken. Three stainless steel (301SS) test sections of different aspect ratios were employed. Nusselt number is found to increase with increasing Radius ratio and Rayleigh number and decrease with increasing aspect ratio. Regression models were developed to predict Nusselt number in terms of aspect ratio, radius ratio and Rayleigh number.

The Father of the Nation late Mahatma Gandhi has enunciated that, any development in the country should be centered on the development of a village. Though several developmental programs have been initiated and executed on various scales, by both Central and State Govt. agencies in Warangal district, micro level planning taking an individual Mandal as a centre has not yet been formulated with full thrust. It is therefore proposed to develop a Decision Support System. The natural resources are considered as more efficient and appropriate for necessary survey and investigation for the assessment of the natural resources and subsequent planning and implementation of various developmental programmes. The Remote Sensing and GIS tools could be helpful in getting the precise and valuable spatial information in understanding the present scenario contemplating with the past data and predicting the future trends. The main objective of the study is to create the Development of Decision Support System (DSS) for MARIPEDA MANDAL and to develop methods for village wise for its efficient utilization and sustainable management and socio-economic development through remote sensing and GIS, Visual Basic techniques. The thematic layers are derived from IRS-ID PAN + LISS-III merged satellite imagery and Survey of India (SOI) topomaps using visual interpretation technique. These maps are converted to digital format using AutoCAD software and further integrated using Arc/Info and Arc View GIS software for the generation of final maps.The socio-economic information collected in the field work and Census book.
This study recommends in micro level planning and in sustainable development of the mandal. using remote sensing and GIS techniques have been used with the assistance of Visual Basic, a user-friendly package having point-and-click graphical user interface (GUI). This information also useful to plan the basic minimum needs of farmers in each village, thereby improving their socio-economic conditions and helps in evolving a broad national policy which can be applied by decision makers for sustainable development of any given study area.
 

X-ray Laue type diffraction patterns were recorded using the image plate system at different temperatures in the nematic phase of 4,4'-Dihexylazoxy- benzene. From the diffused ring, normally observed in the nematic phase and employing three different models the microscopic order parameter has been computed. The order parameter obtained from this technique have been compared with that obtained form optical method. The distribution function estimated at different temperatures in the nematic phase using Deutsch method has also been reported.
 

Cold plasmas have offered considerable breakthrough in diverse scientific areas and have received a great deal of attention in the last three decades. The plasma state of the matter has generated enabling technologies, which integrate the unique properties of the plasma state with processes relevant to scientific and industrial applications. Due to the remarkable feature of cold plasma, the last decade has witnessed its expansion in the biomedical science with its novel applications penetrating several areas in the world of biomedical field. In the present paper, efforts have been made to explore the emerging opportunities of cold plasma in biomedical engineering.

Soils are the natural bodies on which plants grow. In the present study various types of golf course soil samples were analyzed for various parameters. The main objective was to determine the concentration of primary nutrients (N, P and K), secondary nutrients (Ca, Mg and S) and micronutrients (Zn, Fe, Cu and Mn) in the golf course soil samples. Based on the results, we found that the soils are best suited for the golf course.
 

Electro-organic Synthesis of 2-nitrobenzoic acid has been carried out by the electro oxidation of 2-nitrobenzaldehyde studied at different modified electrodes i.e. ruthenium oxide (RuO2) dopped on ebonex ,iridium oxide (IrO2) dopped on ebonex and lead oxide (PbO2) under acidic conditions using galvanostatic techniques. Isolated product was haracterized by T.L.C., usual laboratory qualitative tests and IR, NMR spectral analysis to be 2-nitrobenzoic acid. Effect of different parameters like current density, temperature, depolarizer concentration and nature of anode material on yield percentage and current efficiency have been investigated. Number of electrons have also been calculated to confirm the isolated product to be 2-nitrobenzoic acid.
 

We have studied the alkali halides doped with polar impurities theoretically with the help of generalized <n10> tunneling model with electric field applied along <100> direction. The expression for polarization and contribution to dielectric constant is obtained. The results are compared with <100> tunneling system.
 

Magnetic field affects the physical and physiological activities of our body, hence the composition of the blood. In this paper experimental investigation are presented and analysis the composition of human blood in the presence of magnetic field. The experimental results are obtained in the presence of different magnetic field. Strength (5.46 gauss, 10.90 gauss and 21.84 gauss). It is observed that the effect of magnetic field is to change the data of blood significantly.

The aim of this paper is to obtain a common fixed point theorem for the pair of semi-compatible self maps in a sequentially compact D-metric space, one of them is continuous and by using a functional inequality.
