Taschenbuch. Zustand: Neu. Neuware -The toxicity of silver to bacterial cells is well documented. It has been reported that Ag- nanoparticles are active biocidal agent against Gram +ive Gram -ive bacteria. Silver nanoparticles are non-toxic to human body at low concentration. It inhibits the bacterial growth at very low concentration than antibiotics and has no side effect in patients. Viewing all the above facts, it is necessary to develop a substitute for antibiotics. In this study, silver (Ag) nanoparticles (~6 nm) were synthesized using electro-exploding wire (EEW) technique. Antibacterial action of Ag nanoparticles was studied both in liquid and solid phase using colony forming unit (CFU) detection. Time and dose- dependent study of Ag nanoparticles shows that the effectiveness of particles increases with increasing particle dose and treatment time. This effect was dose-dependent and more pronounced against Gram -ive bacteria compared to Gram +ive bacteria. Transmission electron microscopy result shows particle binding with bacterial cell membrane. Membrane potential assay and cytoplasm diffusion assay show the effectiveness of Ag nanoparticle used in this study.Books on Demand GmbH, Überseering 33, 22297 Hamburg 108 pp. Englisch.

Hardcover. Zustand: New. 1st Edition. Contents: 1. Key parameters in climate change. 2. Green Energy. 3. Bioenergy. 4. Solar energy. 5. Nuclear energy. 6. The carbon cycle. 7. Climate change and health dynamics. The book discusses the problems culminating into climate change and the methods adopted to decelerate. However the basic underlying points causing the above are often a point of interest to beginners. This book simplifies a complicated picture adopting a first principle approach thereby broadening the understanding of climate change. The subject has been elaborated extensively in the book emphasizing need to look for alternate source of energy to control the phenomena of climate change. To emphasize the importance of bioenergy resources and their use is presented in the book. These biological resources which are used to produce biodiesel, bioethanol, biomethanol and their production on a large scale and their possible use in vehicular transport is also discussed in detail.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Soil moisture plays an important role in the runoff process, and its evaluation can be used as a marker of flood risk or drought occurrence. The data is also required to validate the soil moisture component in a variety of soil types of hydrologic models before a possible flood event, and potentially improves the accuracy of their prediction. Keeping the above in view, enormous efforts have gone into measurement of soil moisture by in situ and remote sensing techniques using microwaves. The subject still remains an important point of investigation for it depends upon a number of parameters, for example, texture, topography and shows space and temporal variability. The advantages of both passive and active remote sensing techniques are discussed in detail. The book begins with the basics of soil physics and the soil moisture. Soil moisture measurement techniques presented are confined to microwave frequencies. A summary of theoretical models and a mix-up of experimental and theoretical details is included to offer a comparison. A special chapter is added on an upcoming technique of synthetic aperture radar. The book finally concludes with a summary of recent trends and techniques with a possible direction for future work. The book is primarily aimed to benefit postgraduates and researchers in the area of soil, agriculture physics and microwave remote sensing. The aim is to initiate beginners in the subject. The author will consider his efforts rewarded if it succeeds in such an endeavor.
