Archives of Environmental Protection is the oldest Polish scientifi c journal regarding environmental engineering and protection. It has been published by the Institute of Environmental Engineering of PAS in Zabrze since 1975. The Committee on Environmental Engineering of PAS became its co-publisher in 2011. The quarterly publishes original articles (earlier, also announcements) concerning broadly understood areas of the environmental engineering and protection. The subjects include: air, land and water protection; technologies of fl ue gases, soil and wastewater treatment; transformations and transportation of pollutants in the environment; measurement techniques used in research and engineering as well as environmental monitoring. The published articles also focus on the reclamation and management of derelict lands, environmental management and other questions related to the environmental engineering and protection.The journal has been abstracted by Thomson Scientific since 2006 in the following databases: Science Citation Index Expanded, Biological Abstracts and BIOSIS Previews. Moreover, the journal was given the impact factor (IF) in 2010. The following article presents statistical data as well as a brief history and description of the journal.

The goal of this article is to identify the research problems in application of geomatics technology in forestry, and especially in aspects of the state of forest ecosystems and their sustainable use in future, by reviewing international scientific journals. The selection of journals to be investigated is based upon journal profiles and their scientific prestige. Four journals of geomatics subject are studied for the 2010-2011 period: International Journal of Applied Earth Observation and Geoinformation, International Journal of Geographical Information Science, ISPRS Journal of Photogrammetry & Remote Sensing, Photogrammetric Engineering & Remote Sensing. Critical analysis and bibliometric methods have been used.

Ecological engineering, defined as the design of sustainable ecosystems that integrate human society with its natural environment for the benefit of both, has developed over the last 30 years, and rapidly over the last 10 years. Its goals include the restoration of ecosystems that have been substantially disturbed by human activities and the development of new sustainable ecosystems that have both human and ecological values. It is especially needed as conventional energy sources diminish and amplification of nature's ecosystem services is needed even more. There are now several universities developing academic programs or departments called ecological engineering, ecological restoration, or similar terms, the number of manuscripts submitted to the journal Ecological Engineering continue to increase at an rapid rate, and the U.S. National Science Foundation now has a specific research focus area called ecological engineering. There are many private firms now developing and even prospering that are now specializing in the restoration of streams, rivers, lakes, forests, grasslands, and wetlands, the rehabilitation of minelands and urban brownfields, and the creation of treatment wetlands and phytoremediation sites. It appears that the perfect synchronization of academy, publishing, research resources, and practice is beginning to develop. Yet the field still does not have a formal accreditation in engineering and receives guarded acceptance in the university system and workplace alike.

Tracking the evolution of research in waste recycling science (WRS) can be valuable for environmental agencies, as well as for recycling businesses. Maps of science are visual, easily readable representations of the cognitive structure of a branch of science, a particular area of research or the global spectrum of scientific production. They are generally built upon evidence collected from reliable sources of information, such as patent and scientific publication databases. This study uses the methodology developed by Rafols et al. (2010) to make a “double overlay map” of WRS upon a basemap reflecting the cognitive structure of all journal-published science, for the years 2005 and 2010. The analysis has taken into account the cognitive areas where WRS articles are published and the areas from where it takes its intellectual nourishing, paying special attention to the growing trends of the key areas. Interpretation of results lead to the conclusion that extraction of energy from waste will probably be an important research topic in the future, along with developments in general chemistry and chemical engineering oriented to the recovery of valuable materials from waste. Agricultural and material sciences, together with the combined economics, politics and geography field, are areas with which WRS shows a relevant and ever increasing cognitive relationship.

Available at <a href=http://dx.doi.org/10.1021/jf302505y>http://dx.doi.org/10.1021/jf302505y</a> | Spectral effects of microbial growth, packaging atmosphere and heme oxidation were investigated with fresh salmon. The presence of microorganisms and their growth have little effect on the development of spectral features in fresh salmon during storage prior to extensive spoilage. Important spectral changes occur at 606 and 636 nm in the spectra of fresh salmon during storage. Heme oxidation is the primary source of spectral changes occurring at 636 nm in fresh salmon fillets during air storage. The origin of the shoulder peak appearing at 606 nm is absorption due to water in the salmon muscle. The spectral variations at 606 nm depend on the dominant oxidation state of heme in the muscle and the change in the visibility of the water shoulder peak in the spectrum.

The advancement of the healthcare and biomedical sectors requires the improvement of traditional biomaterials and the development of new and multifunctional biomaterial combinations with enhanced structural and biological performance. The need for biomaterials to help tackle the health problems of an increasing elderly population is continuously growing. Biomaterials science and technology is highly interdisciplinary, which involves not only the established materials science disciplines but also scientific fields such as chemistry, biology, bioengineering and medicine. The increasing impact of nanotechnology in the medical field must also be noted as this implies the development of biomimetic surfaces, nanostructured biomaterials and miniaturized devices. At the last European Congress and Exhibition on Advanced Materials and Processes (EUROMAT 2011: http://euromat2011.fems.eu) held in Montpellier, France in September of last year, the topic of materials for healthcare was covered in three focused symposia, namely: i) bioactive coatings and material-tissue interfaces, ii) smart and biomimetic materials for biomedical applications and tissue engineering and iii) mechanical characterization and modeling of tissues and biomedical materials at all length scales. The oral and poster presentations reflected novel research on biomaterials covering new areas of processing, properties and applications of materials in the biomedical field. A broad variety of topics were presented, ranging from biomaterials for bone replacement, bioactive surfaces and coatings, nanocomposites and tissue engineering scaffolds, bioinspired biocomposites and antibacterial coatings. The eight papers [1–8] published in this special issue of Biomedical Materials were selected from contributions presented at EUROMAT 2011 in the Materials for Healthcare Symposia, specifically for their focus in biomaterials for tissue engineering. It is recognized that successful biomaterials and structures for tissue engineering are those that closely mimic the composition chemistry and hierarchical structure of the native tissues to be replaced and regenerated, including the possibility of adaptation to the biological changes during the healing process, and which exhibit specific mechanical and biological functions to enable rapid new tissue regeneration. The papers selected for this special section went through the normal peer-review process of the journal and cover numerous novel biomedical materials, including a range of inorganic and functionalised bioactive coatings for prosthetic and bone regeneration applications, a series of advanced biodegradable polymer-inorganic composites for tissue engineering and engineered nanocarriers for gene delivery also discussing the interaction of scaffolds with different stem cells. As guest editors of this special section in Biomedical Materials, we are grateful to all authors and reviewers, who have supported this publication with their efforts and hard work, contributing to its timely publication.
