  2. Sustainable Agriculture Reviews 34

    This book is the result of remarkable contribution from the experts of interdisciplinary fields of Science with comprehensive, in-depth and up-to-date research and reviews.​ It describes&nbsp;the applications of date palm for food, medicine and the environmental sectors. Date palm is one of the oldest cultivated trees and its fruit has been a dietary staple around the world for many centuries. Date pulps contain dietary fibers and easily digestible sugars (70%), mainly glucose, sucrose and fructose. They also contain vitamins like biotin, thiamine, riboflavin, ascorbic and folic acid that are important for our body. The date palm fruit has been used in folk remedies for the treatment of various infectious diseases, cancer and immuno-modulatory activity. Date stones and date palm leaves are freely and abundantly available biomass. Therefore, the renovation of agricultural biomass wastes into activated carbons for drinking water purification, wastewater treatment, treatment of dyes, and metal-ions from aqueous solution would add value to agricultural commodities which offer a solution to environmental problems as well as reduce the cost of waste disposal.&nbsp;

  3. Ecology and Evolution of Rhizobia

    <p></p> <p>This book reviews the history and development of rhizobial ecology (diversity, function and interactions with the biotic and abiotic environments), evolution (genome diversification, systematics of symbiotic genes) and application. Further, it describes the new concept of rhizobia, the latest systematic methods, biogeographic study methods, and genomic studies to identify the interactions between rhizobia, legumes and environments. To enable readers to gain a comprehensive understanding of rhizobial biogeography, the book provides effective protocols for the selection and application of high-efficiency rhizobial inoculants. In addition, it presents standard and modern methods used in studies on rhizobial ecology and evolution in dedicated appendices, making it a unique and valuable handbook for researchers.</p> <br> <p></p>

  4. Phyto and Rhizo Remediation

    <p></p> <p>The increasing human population and the associated activities have negatively influenced the ecosystems and life on earth. The continuous addition of agrochemicals, heavy metals and industrial wastes/ effluents in the ecosystems have caused great harm, including loss of productivity, biodiversity, climate change and diseases in plants, animals and humans, resulting in increased marginal lands and endangered sustainability of life on earth. Hence, there is an urgent need to reverse the impact of dangerous pollutants through a holistic, sustainable and biotic approach. Bioremediation involves the utilization of biological systems, mainly plants (phytoremediation) or microorganisms or both in combination (rhizoremediation) for the removal or degradation of pollutants and revive the habitats in an eco-friendly manner. Recently, there have been many success stories related to bioremediation involving plants or plant-microbe interactions. These success stories are related to the removal of heavy metals, pesticides, polyaromatic hydrocarbons, explosives, radionuclides or reduction of biological oxygen demand, total dissolved solids, total suspended solids, oil spills in water bodies. Rhizoremediation has also been successfully used for reclamation of saline or marginal soils. With the range of pollutants and the total area (on earth) covered by these toxic chemicals, it is important that these eco-friendly technologies be utilized in a better way. The book throws light on the recent happenings, research and success stories related to bioremediation of polluted habitats through phytoremediation or rhizoremediation. The book also highlights some of the significantly important plant and microbial species involved in remediation, the physiology, biochemistry and the mechanisms of remediation by various plants and microbes, and suggestions for future improvement of bioremediation technology. </p> <br> <p></p>

  5. Identity Structure Analysis and Teacher Mentorship

    This book examines the benefits of applying the Identity Structure Analysis (ISA) to teacher professional development. At present no government, local authority or school is actively applying Identity Structure Analysis to monitor school improvement: in a profession where turnover is extremely high, ISA is framed as a way for professional development to meet the needs of the specific teacher. Examining idiographic ISA analyses as well as practical advice for implementing professional development programs, the authors scrutinise how ISA can be used in conjunction with mentoring to offset teacher turnover. This practical volume will be of interest and value to scholars and researchers of teacher identity and professional development, as well as researchers and policymakers interested in reducing teacher turnover.&#xa0; <br>

  6. Circular Economy: Global Perspective

    A circular economy is an alternative to a traditional linear economy (make, use, dispose) in which we keep resources in use for as long as possible, extract the maximum value from them whilst in use, then recover and regenerate products and materials at the end of each service life. Circular economy (CE) is important towards sustainable development, resources circulation and conservation, involving closing of material loops and cascading used resources, to prevent waste occurrence, and transforming the resulting residual streams into new (secondary) resources.&nbsp; Strategies and legislative framework for waste management are important steps for development of a more CE where resource efficiency becomes the key driver for both economic growth and environmental protections.&nbsp; A few countries achieved good results implementing CE as a replacement of the linear economy. Resource managers and planners should thoroughly identify factors to implement CE for societal benefits. This book presents how resource consumption is minimized with rational use based on 3Rs, legislative framework and government supports towards implementing CE initiatives, example of best practices, future plans and targets in different countries those are helpful for researchers, planners and implementers.

  8. Exploring Police Integrity

    This work provides an innovative new look at police ethics, including results from an updated version of the classic Police Integrity Questionnaire, including new social and technological advances. It aims to push the study of police research further, expanding on and testing police integrity theory and methodology, the relationship between community and integrity, and the influence of multiculturalism and globalization on policing and community attitudes. <div> <br> </div> <div> This work brings together experienced scholars who have used the police integrity theory and the accompanying methodology to measure police integrity in eleven countries, and provide advance and sophisticated explorations of the topic. Organized into three thematic sections, it explores the testing methodology for international comparisons, insights into police-community relations, and explores police subcultures. <br> <br>This innovative book will be of interest to researchers in criminology &amp; criminal justice, particularly with an interest in policing, as well as related fields such as sociology, public policy, and comparative law. </div>
