This volume is addressed to historians of science, Egyptologists and Assyriologists dealing with the history of early science. It presents the proceedings of two workshops held at the Goethe-University Frankfurt/Main, focusing on traditions of systematic knowledge in Ancient Egypt and Mesopotamia. Assuming that written knowledge was preserved and transmitted intentionally in both cultures, paradigms of knowledge can be reflected by the texts. Although the available source material is subject to their find spots and the vagaries of preservation, by asking specific questions the sources can provide insights into the work of the ancient scholars. The text corpora presented in this volume come from the fields of medicine, magic and ritual, astronomy, mathematics and law. The authors use the sources to provide overviews of the discussed knowledge areas and to discuss certain aspects of the traditions in more detail.

In September 2013 the VDZ extended a warm welcome to the delegates of the 7th International VDZ Congress "Process Technology of Cement Manufacturing". From 25 - 27 September the congress again served as a forum for the cement industry, with engineers, researchers and equipment suppliers sharing their knowledge on state-of-the-art cement manufacturing technology.Nearly forty speakers from around the world reported on their specialist fields. More than six hundred participants from almost 50 countries heard lectures on topics of high relevance to those working along the value chain of cement and concrete. In times of an about-turn in energy policy, sustainability, energy efficiency and the use of natural resources were again key topics, as well as technical advancement in grinding and burning technology. An outlook on future developments in the global cement and energy markets and research reports on new cements completed the congress programme.Even if the global economy is still facing enormous challenges and the economic growth of the emerging countries has slowed down, cement remains a building material without which modern society could not function. Technological progress and the predicted increase in global demand for cement are the basis for the future growth of our industry. The VDZ Congress 2013 has once again illustrated how cement producers and users, researchers and equipment suppliers can work together to successfully master the challenges our industry faces.

Increased industrial and agricultural activity has led to the contamination of the earths soil and groundwater resources with hazardous chemicals. The presence of heavy metals, dyes, fluorides, dissolved solids, and many other pollutants used in industry and agriculture are responsible for hazardous levels of water pollution. The removal of these pollutants in water resources is challenging. Bioremediation is a new technique that employs living organisms, usually bacteria and fungi, to remove pollutants from soil and water, preferably in situ. This approach is more cost-effective than traditional techniques, such as incineration of soils and carbon filtration of water. It requires understanding how organisms consume and transform polluting chemicals, survive in polluted environments, and how they should be employed in the field. Bioremediation for Environmental Pollutants discusses the latest research in green chemistry and practices and principles involved in quality improvement of water by remediation. It covers different aspects of environmental problems and their remedies with up-to-date developments in the field of bioremediation of industrial/environmental pollutants. Volume 1 focuses on the bioremediation of heavy metals, pesticides, textile dyes removal, petroleum hydrocarbon, microplastics and plastics. This book is invaluable for researchers and scientists in environmental science, environmental microbiology, and waste management. It also serves as a learning resource for graduate and undergraduate students in environmental science, microbiology, limnology, freshwater ecology, and microbial biotechnology.

Regional bird field guides are few and far between in South Australia and Chris Baxters photographic guide to the birds of Kangaroo Island is the stand-out in this genre. This comprehensive account covers all 267 bird species recorded on the Island or offshore over the seas. It builds on the annotated list produced by the same author in 1989 and revised in 1995. The photographs provided by some of Australias most highly regarded photographers beautifully illustrate the detailed descriptions of the birds, their habits, habitats, breeding, status, abundance and distribution on the Island. In addition there are recommendations on where to look for each species, with cautions about not getting too close to endangered birds and their nests. Chris Baxter has called on a lifetime of bird watching on Kangaroo Island and observations from visitors and residents to present an attractive field guide that is a must for all birdwatchers from casual observers to serious ornithologists.

Phytochemical compounds are secondary metabolites that plants usually synthesize for their own protection from pests and diseases. Phytochemical biosynthesis is also triggered under specific environmental conditions. They cannot be classified as essential nutrients since they are not required at specific amounts for life sustenance. Phytochemicals in Vegetables: A Valuable Source of Bioactive Compounds presents information about the phytochemical (common and scarce) content of several cultivated vegetables, as well as their health and therapeutic effects based on in vitro, in vivo, animal and clinical studies. Chapters also cover recent research findings about their mode of action, bioavailabity, interactions with other biological matrices and pharmacokinetics. Moreover, the book gives special attention to the factors that may alter and modulate bioactive compound content, including both cultivation practices and post-harvest treatments that aim towards the production of high quality and healthy foods. Researchers, public health workers, consumers and members of the food industry will find this book to be a useful reference on the variety of phytochemicals present in vegetables.

Marine ecosystems offer several benefits to human communities. To make sustainable use of these benefits, it is necessary to elucidate and conserve marine ecology, and strive to maintain a sustainable natural resource management program. For this reason, understanding the diversity and behavior of both macro-ecosystems and micro-ecosystems are crucial. Monitoring Artificial Materials and Microbes in Marine Ecosystems explores microbial roles and their interaction with artificial materials in marine environments. After starting with simple topics for beginners, chapters explore methods to detect microorganisms in marine ecosystems and interactions of marine organisms with artificial materials. The sequential progression into advanced topics makes it easier to understand how to solve the reduction in marine-ecosystem viability caused by adverse events. Readers are provided with useful information for rehabilitating marine environments to make them sustainable for communities. Topics are covered in 3 parts: Part 1 is an introductory guide to marine ecosystems and environmental monitoring assessment. Readers are introduced to coral reef ecosystems, algal blooms and the role of environmental monitoring services in maintaining and restoring the quality of marine environments. This is followed by examples of sustainable marine environment assessment.Part 2 provides information about methods to detect microorganisms (viruses and bacteria) and evaluate marine environments. This includes sample enrichment methods, electrochemical analysis, and single cell imaging techniques. The highly sensitive and specific techniques presented in the book, are applicable in a wide variety of situations.Part 3 is dedicated to interactions between artificial metallic materials and microorganisms in marine environments. Chapters in this section share results from several experiments conducted to separate microorganisms and biofilms from such environments. This book is intended primarily for marine ecologists, microbiologists, environmental engineers, and engineers associated with industrial projects.
