[en] Monitoring and control the hunting activity is primordial to guarantee its sustainability. However, the governmental agencies responsible to manage hunting commonly are unable to adequately do this job because the thousands of small private hunting states, associated exclusively by political-administrative criteria. In this work, we provided a new management tool through the establishment of a hunting regions system. Area of study: Castilla-La Mancha region, central Spain. Material and methods: We used a two-stage procedure to establish the environmental units than, afterwards, were characterized on a set of hunting variables. Main results: We generate a hunting regionalization with 12 hunting regions and proposed regional hunting yields for each of the hunting regions. Research highlights: The use of hunting regions will permit to define the game management practices more appropriately on a large scale, but also, will facilitate the tasks of assessment, management and monitoring of game of the number hunting states included in each hunting region.
[en] This Process Knowledge Summary Report summarizes the information collected to satisfy the transportation and waste acceptance requirements for the transfer of transuranic (TRU) waste between the Materials and Fuels Complex (MFC) and the Advanced Mixed Waste Treatment Project (AMWTP). The information collected includes documentation that addresses the requirements for AMWTP and the applicable portion of their Resource Conservation and Recovery Act permits for receipt and treatment of TRU debris waste in AMWTP. This report has been prepared for contact-handled TRU debris waste generated by the Idaho National Laboratory at MFC. The TRU debris waste will be shipped to AMWTP for purposes of supercompaction. This Process Knowledge Summary Report includes information regarding, but not limited to, the generation process, the physical form, radiological characteristics, and chemical contaminants of the TRU debris waste, prohibited items, and packaging configuration. This report, along with the referenced supporting documents, will create a defensible and auditable record for waste originating from MFC.
[en] When a waste generated, treated, or disposed of at a site in the United States is classified as hazardous under the Resource Conservation and Recovery Act and is destined for land disposal, the waste manager responsible for that site must select an approach to comply with land disposal restrictions (LDR) treatment standards. This paper focuses on the approach of obtaining a variance from existing, applicable LDR treatment standards. It describes the types of available variances, which include (1) determination of equivalent treatment (DET); (2) treatability variance; and (3) treatment variance for contaminated soil. The process for obtaining each type of variance is also described. Data are presented showing that historically the U.S. Environmental Protection Agency (EPA) processed DET petitions within one year of their date of submission. However, a 1999 EPA policy change added public participation to the DET petition review, which may lengthen processing time in the future. Regarding site-specific treatability variances, data are presented showing an EPA processing time of between 10 and 16 months. Only one generically applicable treatability variance has been granted, which took 30 months to process. No treatment variances for contaminated soil, which were added to the federal LDR program in 1998, are identified as having been granted.
[en] A brief description of the difference between a compression and an absorption heat pump is made, and the reasons why absorption systems have spread lately are given. Studies and projects recently started in the field of absorption heat pumps, as well as criteria usually followed in project development are described. An outline (performance targets, basic components) of a project on a water/air absorption heat pump, running on natural gas or LPG, is given. The project was developed by the Robur Group as an evolution of a water absorption refrigerator operating with a water/ammonia solution, which has been on the market for a long time and recently innovated. Finally, a list of the main energy and cost advantages deriving from the use of absorption heat pumps is made
[it]Richiamate succintamente le peculiarita' che distinguono le pompe di calore a compressione da quelle ad assorbimento, l'articolo evidenzia le ragioni del progressivo affermarsi dei sistemi ad assorbimento. Vengono elencati gli studi ed i progetti avviati negli ultimi anni nel settore delle pompe di calore ad assorbimento ed i criteri che, di norma, guidano lo sviluppo dei progetti. Viene successivamente descritto, nelle linee essenziali (obiettivi prestazionali, componenti di base), il progetto della pompa di calore ad assorbimento aria/acqua, alimentata a metano o a GPL, sviluppato da Robur Group come evoluzione del refrigeratore d'acqua ad assorbimento operante con soluzione acqua/ammoniaca, da lungo tempo sul mercato ed innovato nel corso degli ultimi anni. Conclude l'articolo l'elenco dei principali vantaggi di carattere energetico ed economico derivanti dall'impiego di pompe di calore ad assorbimento
[en] The paper describes that the growing stock and natural regeneration of teak and other valuable commercial species in Myanmar's forests are fast declining due to successional changes in forest types, repeated severe annual forest fires, fuel wood crisis, and over exploitation, thereby necessitating new research approaches and concepts in the treatment of our forests
[en] The natural environment comprises non-biological elements such as air, water, light, heat and biological elements of animal and plant life; all interact with each other to create an ecosystem. Human activities like over-exploitation of forest results in deforestation and desertification. This consequently changes ecological balance. Topics on: (1) history of elephants utilization; (2) elephant logging; (3) classification of elephants; (4) dragging gear; (5) elephant power; (6) elephant logging and environment, are discussed
[en] IMPAK is quarterly bulletin of the Department of Environment, Malaysia. In this issue, IMPAK's theme is Sustainable Development. It is observed that while definitions of sustainable development appear to differ from one writer to another, they share one common theme, i.e. all contains three fundamental concepts, environment, futurity and equity. Article from DOE news is Bandar Lestari, an environment award with the aims to accord recognition to one urban center that has shown its overall commitment and effort towards achieving environment sustainability in its development. Feature article to support IMPAK's theme are Sustainable Consumption, Where are We Heading? Explanations on correlation between population growth and the economic consumption of the earth resources, New Approaches for the Sustainability of Malaysian Industries suggestion for alternative development strategies with the new environment management system, and the last article is Managing Soil Erosion for Sustainable Farming few approaches to achieve efficient erosion control. Meanwhile Biomass: Renewable Energy Sources in Malaysia fill up the Technical Update section
[en] The Pollution Prevention Program Office has increased recycling activities, reuse, and options to reduce the solid waste streams through streamlining efforts that applied best management practices. The program has prioritized efforts based on volume and economic considerations and has greatly increased Los Alamos National Laboratory's (LANL's) recycle volumes. The Pollution Prevention Program established and chairs a Solid Waste Management Solutions Group to specifically address and solve problems in nonradioactive, Resource Conservation and Recovery Act (RCRA), state-regulated, and sanitary and industrial waste streams (henceforth referred to as sanitary waste in this paper). By identifying materials with recycling potential, identifying best management practices and pathways to return materials for reuse, and introducing the concept and practice of open-quotes asset management,open-quotes the Group will divert much of the current waste stream from disposal. This Group is developing procedures, agreements, and contracts to stage, collect, sort, segregate, transport and process materials, and is also garnering support for the program through the involvement of upper management, facility managers, and generators
