The purpose of this book will to prepare Pyridostigmine nanoparticles for control release of Pyridostigmine to improve the oral bioavailability, enhance the solubility and dissolution rate by decreasing particle size of drug. Infrared spectroscopic studies confirmed that there was no interaction between drug and polymers. The controlled release Pyridostigmine nanoparticles were prepared by Solvent evaporation by using Ethyl cellulose, Chitosan & HPMC K100 at different ratios. The production yield of the formulated controlled release nanoparticles (F1 to F16) in the range of 76.11 % to 83.58...

Le but de ce livre sera de préparer des nanoparticules de pyridostigmine pour contrôler la libération de pyridostigmine afin d'améliorer la biodisponibilité orale, d'améliorer la solubilité et le taux de dissolution en diminuant la taille des particules du médicament. Des études spectroscopiques infrarouges ont confirmé qu'il n'y avait pas d'interaction entre le médicament et les polymères. Les nanoparticules de pyridostigmine à libération contrôlée ont été préparées par évaporation de solvant en utilisant de l'éthylcellulose, du chitosan et du HPMC K100 à différents...

This book presents a geospatial analysis of Varanasi's urban expansion from 1972-2020. It shows that growth has been largely unplanned, with rapid, unregulated land-cover change, especially in peri-urban areas. Using GIS, remote sensing, and indices such as the Annual Urban Expansion Rate, Urban Expansion Intensity Index, and Urban Expansion Differentiation Index, it quantifies and maps growth patterns. The book links historical, cultural, and colonial influences to current urban form and reveals a gap between planning frameworks and ground realities, resulting in loss of farmland and green...

Dieses Buch enthält eine raumbezogene Analyse der Stadterweiterung von Varanasi im Zeitraum 1972-2020. Es zeigt, dass das Wachstum weitgehend ungeplant war und sich die Bodenbedeckung vor allem in stadtnahen Gebieten schnell und unkontrolliert verändert hat. Mithilfe von GIS, Fernerkundung und Indizes wie der jährlichen Stadterweiterungsrate, dem Stadterweiterungsintensitätsindex und dem Stadterweiterungsdifferenzierungsindex werden die Wachstumsmuster quantifiziert und kartiert. Das Buch stellt eine Verbindung zwischen historischen, kulturellen und kolonialen Einflüssen und der...
