Papadopoulos, "Ephyra-Epirus: The Mycenaean Acropolis: Results of the Excavations 1975-1986 and 2007-2008" English | ISBN: 1789693713 | 2020 | 148 pages | PDF | 18 MB Ephyra-Epirus: The Mycenaean Acropolis presents the results of the 1975-1986 and 2007-2008 excavations on the prehistoric-Mycenaean acropolis of Ephyra, one of the most important Bronze Age sites of Epirus. Ephyra is a small coastal fortified site in the region of the lower Acheron valley and the only one that has been systematically excavated, producing impressive and, in some cases, unique Bronze Age remains (architectural, burial, pottery, artefacts). It stands on a high hill, in an exceptional position that overlooks and commands the lower Acheron valley and provides easy access both to the nearby Glykis Limin, the Ionian sea and the hinterland. Moreover, it is surrounded by three successive perivoloi, two of which (middle and lower) belong to LH III times, with a monumental south entrance gate.

Free Download Enzymatic Transformation By Soundar Divakar (auth.) 2013 | 284 Pages | ISBN: 8132208722 | PDF | 9 MB Transformations using enzymes have been extensively investigated in the last two decades and the results promise great potential for this growing field, especially in the area of synthetic organic chemistry mainly due to of its many advantages. Accordingly, this book has attempted to bring out the advantages of using enzymes involving complex underivatized and unprotected substrates in non-polar media under homogenous and heterogeneous reaction conditions. Merits and demerits of using enzymes in terms of yields and selectivity/specificity are presented without any prejudice. Almost all the reactions dealt with are from the author's laboratory comprising diverse substrates, and the catalysis involves two important hydrolyzing enzymes, extensively examined for the reverse reactions. Thus, esterification involving lipses and glycosylation involving glycosidases were investigated with respect to various strategies like optimization of reaction conditions, response surface methodology and kinetics, carrying out reactions under solvent, non-solvent and super critical carbon dioxide conditions. In short, the work presented is to ensure the comprehension of the problems faced by the researchers in this area so as to work out further efficient strategies for carrying out enzymatic transformations in the laboratory successfully with better yields and specificity.

Free Download Environmental Protection Strategies for Sustainable Development By Abdul Malik, Mashihur Rahman (auth.), Abdul Malik, Elisabeth Grohmann (eds.) 2012 | 606 Pages | ISBN: 9400715900 | PDF | 7 MB The environment of our planet is degrading at an alarming rate because of non-sustainable urbanization, industrialization and agriculture. Unsustainable trends in relation to climate change and energy use, threats to public health, poverty and social exclusion, demographic pressure and ageing, management of natural resources, biodiversity loss, land use and transport still persist and new challenges are arising. Since these negative trends bring about a sense of urgency, short term action is required, whilst maintaining a longer term perspective. The main challenge is to gradually change our current unsustainable consumption and production patterns and the nonintegrated approach to policy-making. This book covers the broad area including potential of rhizospheric microorganisms in the sustainable plant development in anthropogenic polluted soils, bioremediation of pesticides from soil and waste water, toxic metals from soil, biological treatment of pulp and paper industry wastewater, sustainable solutions for agro processing waste management, solid waste management on climate change and human health, environmental impact of dyes and its remediation. Various methods for genotoxicity testing of environmental pollutants are also discussed and chapters on molecular detection of resistance and transfer genes in the environmental samples, biofilm formation by the environmental bacteria, biochemical attributes to assess soil ecosystem sustainability, application of rhizobacteria in biotechnology, role of peroxidases as a tool for the decolorization and removal of dyes and potential of biopesticides in sustainable agriculture.It offers a unique treatment of the subject, linking various protection strategies for sustainable development, describing the inter-relationships between the laboratory and field eco-toxicologist, the biotechnology consultant, environmental engineers and different international environmental regulatory and protection agencies.

 Free Download Environmental Adaptations and Stress Tolerance of Plants in the Era of Climate Change By Hans-Werner Koyro, Parvaiz Ahmad (auth.), Parvaiz Ahmad, M.N.V. Prasad (eds.) 2012 | 515 Pages | ISBN: 1461408148 | PDF | 9 MB Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It also provides information as to how phytoconstituents, hormones and plant associated microbes help the plants to tolerate the stress. This volume also highlights the use of plant resources for ameliorating soil contaminants such as heavy metals.Dr. Parvaiz is Assistant professor in Botany at A.S. College, Srinagar, Jammu and Kashmir, India. He has completed his post-graduation in Botany in 2000 from Jamia Hamdard New Delhi India.
