Phosphorus is a key nutrient for increasing productivity and also most important single factor responsible for poor productivity of pulses particularly soyabean in India. Its deficiency in soils is widespread and its use efficiency is very low. Next most important emerging nutrient that is showing widespread deficiency in pulse crops is sulphur. It plays an important role in synthesis of sulphur containing amino acids, vitamins, metabolism of carbohydrates, proteins etc. In recent past, sulphur is also becoming a key nutrient in pulse production. Hence, combined application of phosphorus and sulphur must be one of the most important strategies to increase productivity of pulse crops in India.

The traditional treatment for brain cancer includes surgery, Radiotherapy and chemotherapy. The neurosurgeon usually plans the surgery by utilizing two Dimensional MRI images. It is difficult to determine the size and exact location of tumor for safest surgical approach to minimizing permanent damage to normal tissue. In this study such problems are minimized by creating the 3D printed models of brain tumors from medical imaging processing software by utilizing MRI data sets. The data from MRI has been saved as DICOM (Digital Imaging and Communications in Medicine). The 3D model of patient¿s specific brain tumor will be produced by interfacing DICOM data with 3D slicer. 3D printer can produce solid 3D model using STL file generated from 3D slicer. 3D printed model of Brain Tumor could serve as a tool for preoperative surgical planning.

Increasing demand of energy day by day and depletion of fossil fuels, it focuses our attention towards unconventional energy resources. From all of the sources available to us solar energy is the best option with minimum environmental impact. But the problem lies in efficiently collecting and converting this energy in to something useful form. The present study has been carried out to increase the performance of flat plate solar collector by using micro channel collector plates.

This book is written on Dental laws and Ethics and deals with various methods to safeguard the interests of the consumers as well as dental professionals. It throws light on to the fact of moral ethics which enables a person to judge what is right and what is wrong. It emphasizes the need to take effective steps to improve the awareness of dental professionals towards various rules pertaining to their field. It is incumbent on all professionals to embrace the principles in everyday working life. It is important that dental professionals are aware of their consumer rights.

This book is basically a ¿one stop¿ information for wound and wound healing strategies, potentials & guidance for research. Wound healing involves components like platelets, neutrophils, fibronectin, macrophages, fibroblasts, endothelial cells, keratinocytes, collagen, proteoglycans. It is also promoted by various growth factors such as platelet-derived growth factor, transforming growth factor, epidermal growth factor, vascular endothelial growth factor, fibroblast growth factor. There are different methods of wound debridement such as autolytic debridement, bio-surgery, sharp debridement and surgical debridement. Animal models are very important to determine the factors that may affect the multifactorial nature of the healing process of wound and disorders associated with delayed wound healing. There are numerous models in-vitro and in-vivo that are developed to determine the mechanisms involved in the healing process. This book also encompasses glimpse of various plants used for wound healing.

Repetitive Corrugation and Straightening (RCS) process is one of the Severe Plastic Deformation (SPD) techniques which introduces a large amount of plastic deformation in a sheet workpiece without significantly changing its cross-sectional geometry. In present work experimentation and Finite Element (FE) study of Repetitive Corrugation and Straightening (RCS) process is being attempted. The work is done in two parts i.e. Finite Element Study and Experimentation work. In the Finite Element study, the effect of triangular and circular teeth effect has been studied and an intermediate teeth design is used. The teeth are of triangular in shape with a rounded top. Experimentation of RCS process is attempted with a 100mm x 100mm x 1 mm of Al6061 sheet. Experimentation was performed for three cycles of RCS process giving 90° Clockwise rotation along the perpendicular axis to the surface after each pass. Three mechanical tests were performed viz. Micro Hardness test, Tensile test and Stiffness test. To study the effect of the process these tests were performed on processed as well as unprocessed sheet sample. The hardness test shows an increase in hardness after every pass.

Medical image fusion is a process which merges information from multiple images of the same scene. The fused image provides appended information that can be utilized for more precise localization of abnormalities. The use of medical image processing databases will help to create and develop more accurate and diagnostic tools.

The book initially presents the basic concepts related to the Semantic Web, Semantic Web-based applications, Web applications, Ontology, and their qualitative aspects. It then presents the evaluation of the structural quality of modular ontologies and review on metrics for the evaluation of ontology behavior.Further, the book discusses the qualitative evaluation of Semantic Web applications deployed on the Cloud, helping readers understand, maintain, integrate, and reuse these applications. The book offers software engineers in general and ontology engineers in particular a single, valuable guide to help them find the best modularization on the basis of goodness of (re) use. It can also serve as an initial source of information for starting research in this domain.

The book includes fundamental concepts such as introduction and classification of liquid dimers, as well as advance topics including bent-core liquid crystal dimers and discotic-calamitic liquid crystal dimers.
