The combined use of remotely-sensed images and GIS based environmental applications in this work is needed for systematic ideas and scientific planning in the Darbhanga district of Bihar. The index-based classification method was followed in an ArcGIS software and as a result, various indices such as NDVI, NDWI, MNDWI (Esri), MNDWI (IHS) had been obtained to assess the water-logged portions. The total area subjected to water-logging in the Darbhanga district was found to be 42,282 ha. The area of water-logging was found in the two sub-divisions of the Darbhanga district. The blocks of Darbhanga and Biraul sub-division, holding the water-logging area of 21,899 ha and 20,383 ha respectively. The surface drainage plan for the blocks of Darbhanga and Biraul sub-divisions have been expressed by showing the main drain lines and outlets which was based on the comparison of different thematic maps. The useful measures also have been suggested to execute the drainage plan in an active manner.

A diehard pilot, a dedicated son, a devoted father is arrested, assaulted and abandoned in the mental asylum. What happens next is unexpected... It is the tale of trials, tribulations and triumph of the indefatigable human spirit against all odds. The spirit that refuses to bow down in subservience to injustice and raises its head in reverence to itself. Excerpts from the book Most of the world's greats have suffered silently in solitary confinements, Gandhi for six and Mandela for twenty-seven years. It led to their transformation. The seed of greatness buried deep in their souls got the time and environment to germinate after the gestation period. It's like phototropism-the greatness seed germinates in the dark dungeons of the icy cell and gravitates towards the light of truth to flourish and be free forever. Cocooned in the close confines of the cell, the caterpillar metamorphoses into a butterfly. The transformation is permanent and irreversible.

Geographic Information Systems (GIS) play a pivotal role in the field of urban planning and management and provide better solutions for numerous urban problems. With GIS, one has the ability to better understand existing requirements of a city and its design to fulfill those needs. This book contributes to developing scientific knowledge based on geospatial technologies among planners, researchers, scientists, professionals, students, and laymen and providing them with better understanding for urban planning and management at various levels. The book manifests the importance of GIS in better understanding of current urban challenges and provides new insights on how to apply GIS in urban planning. It also encourages the various stakeholders of society to participate in the decision-making process and assists planners and authorities to formulate suitable plans for sustainable urban growth of a region. The book is divided into two parts. The first part describes thefundamental concepts of GIS and also deals with the advanced techniques of spatial planning. The second part addresses real-world case studies using various applications of GIS. The case studies include urban land-use changes, simulation of future urban growth, urban heat island, alternate landfill site selection and urban flood susceptibility mapping, among others. This book shows how to integrate GIS with remote sensing, geostatistics, artificial intelligence-machine learning techniques, and other cutting-edge technologies. Readers find this book to be an invaluable resource for understanding and solving problems relating to sustainable urban planning and management.

The research work reports the fabrication and characterization of PMMA nanocomposites using various nanofillers such as nanoclay (OMMT), Co-Al LDH, Cu-Cr LDH and Ni-Al LDH. The melt intercalation and solvent blending techniques were employed for the preparation of PMMA nanocomposites. The different properties of PMMA nanocomposites were examined by using XRD, TEM, FESEM, FTIR, DSC, TGA, DMA, tensile, flexural, impact, hardness, flammability and rheological analysis. The initial part addresses the fabrication and characterization of PMMA/OMMT nanocomposites by melt intercalation technique. Thereafter, the influence of different compatibilizers on the properties of PMMA/clay nanocomposites is discussed. The further section deals with the development of layered double hydroxides (LDHs) based PMMA nanocomposites (PMMA/Co-Al LDH, PMMA/Cu-Cr LDH and PMMA/Ni-Al LDH) containing various concentration of LDHs (1-7 wt.%). Subsequently, the final part describes the characterization of PMMA/OMMT, PMMA/Ni-Al LDH and PMMA/Co-Al LDH nanocomposites prepared by solvent blending method.

Dans diverses sources de m decine indig ne et traditionnelle, les plantes ont t largement utilis es pour le traitement. L'exploration des constituants chimiques des plantes et leur criblage pharmacologique peuvent nous fournir la base pour le d veloppement de nouveaux agents pour le traitement de diverses affections. Annona squamosa, commun ment appel e "pomme-cr me", est galement largement utilis e comme m dicament traditionnel dans diverses cultures. Le nom du genre "Annona" vient du mot latin "anon", qui signifie "produit annuel", en r f rence la production de fruits des diff rentes esp ces de ce genre. Traditionnellement, les feuilles de la plante sont utilis es sur les plaies pour favoriser la cicatrisation. Une plaie peut tre infect e par divers pathog nes microbiens et Staphylococcus aureus est le pathog ne de plaie le plus commun ment signal . Il a t tabli que les pathog nes microbiens retardent la cicatrisation des plaies par plusieurs m canismes diff rents. Dans la pr sente tude scientifique, l'isolement et l'identification de Staphylococcus aureus ont t effectu s partir de plaies contamin es.
