Organisations today face increasing environmental constraints, e.g. in the form of legal and customer requirements; the defence sector is no exception. There is a need to evaluate and limit environmental effects of defence activities and materiel. In this study we used quantitative Life Cycle Assessment (LCA) and a method for simplified LCA (the Material, Energy, Chemicals and Others (MECO) method) to assess the environmental impacts of a grenade. The aims of the study are to identify aspects in the grenade's life‐cycle that have the largest environmental impact, suggest improvement possibilities, make a comparison between different approaches for waste management of munitions, and to perform a demonstrative case for the application of LCA to munitions. Significant environmental aspects of the grenade's life‐cycle include use of metals, use of fossil fuels, and detonation outdoors. The study shows that an LCA can be used to analyse environmental impacts from munitions. The simplified LCA gave information that is complementary to the quantitative LCA.

EPDM elastomers have been synthesized by the Ziegler-Natta oatalytic system VOCl3/Al2Et3Cl3 with the objetive of verifying the influence of termonomers on terpolymer synthesis and on the properties of peroxide-vulcanized terpolymer compositions. Two groups of termonomers have been studied. Dienes, i.e., dicyclopentadiene (DCP), 5-ethylidene-2-norbornene (ENB) and limonene, and aromatic compounds, i.e., indene (IND) and styrene (ST). The influence on the synthesis has been verified by yield, termonomer incorporation, and molecular weight distri bution. The vulcanizate properties have included mechanical and electrical properties. 相似文献

Zusammenfassung Das Interesse der Unternehmen, an personenbezogene Daten zu gelangen und diese für Werbezwecke zu verwerten, ist gro?. An
die Einholung von Einwilligungen zur Verarbeitung solcher Daten stellte die Rechtsprechung daher hohe Anforderungen. Die herrschende
Meinung ging bislang davon aus, dass Einwilligungen in Werbema?nahmen, die mittels Opt-out-Verfahren erlangt wurden, unwirksam
sind. Bereits im vergangenen Jahr hatte das Oberlandesgericht München erneut darüber zu entscheiden, ob eine Opt-out-Klausel
den datenschutzrechtlichen Anforderungen nach § 4a BDSG entspricht — und bejahte überraschenderweise die Wirksamkeit der Einwilligung. 相似文献

20 depressed patients with major depressive disorder, 20 nondepressed matched control Ss, and 17 patients with anxiety disorders were compared in different measures of social problem solving. Problem solving was assessed with the Means-Ends Problem-Solving Test (Study 1), the solution of personal problems, and a problem-solving questionnaire (Study 2). Results showed that, as predicted, depressed Ss suffered from a deficit in problem solving in all 3 measures. The majority of these deficits were also displayed by the clinical control group rather than being specific to a diagnosis of depression. However, depressed Ss produced less effective solutions than did normal and clinical control Ss. The results suggest that depressed and anxious patients may have difficulties at different stages of the problem-solving process. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

High‐Affinity Carbohydrate Binding by Trimeric Benzoboroxoles Measured on Carbohydrate Arrays 下载免费PDF全文

Carbohydrates are involved in a wide range of biological processes of pharmaceutical relevance. The selective recognition of carbohydrates is therefore of great interest in biology and medicine. In this study we present the synthesis of fluorescent multimeric benzoboroxoles and the analysis of multivalent binding processes to immobilized carbohydrate arrays by fluorescence spectroscopy. We observed high binding affinities of trimeric benzoboroxoles by determination of KDsurf values for their interaction with α‐Gal on glass chips. The observed KDsurf values were in the mid‐nM range (49 and 104 nM ) and are comparable to the KDsurf values for binding of natural lectins, such as that of ConA to immobilized α‐Man (79 nM ). The array technology was found to be an excellent tool for studying the binding processes of multivalent lectin mimetics with respect to profiling and quantitation. 相似文献

The major objective of the present study was to examine whether approach versus avoidance commitment to one's intimate relationship was differentially predictive of relationship quality parameters in the long run. In the 1st testing period, 134 participants (67 romantic couples) answered questions about approach- versus avoidance-related measures. Commitment and relationship quality parameters such as satisfaction and emotions depending on the partner's presence were assessed in all 3 testing periods. The proposed distinction between an approach and an avoidance type of commitment was validated through correlations with other approach- versus avoidance-related measures. Longitudinal analyses revealed that approach commitment predicted relationship quality parameters positively, whereas avoidance commitment predicted them negatively. The results are discussed in terms of the benefit of an approach-avoidance-based conceptualization of commitment. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Species richness, structural diversity and species composition in meadows created by visitors of a botanical garden in Switzerland 总被引:3,自引:0,他引:3
Biodiversity is an increasingly important criterion in designing ecological compensation areas and urban green areas. However, little is known about how important biodiversity is to the general public. This paper presents the results of two complementary studies investigating the meadow preferences of visitors to a botanical garden in Switzerland. In the first study, 152 people were asked to create their own favourite meadow patch by selecting 25 out of 779 local wild plants (54 species) that were displayed in flowerpots. In the second study, 143 people were asked with the help of a written questionnaire to imagine a bare piece of land the size of 100 m × 100 m close to their place of living and mentally create the meadow of their dreams. In both cases, study participants assembled meadows that were species-rich and rich in structural diversity (expressed by plant height and leaf forms). Moreover, they explicitly stated diversity as their main assemblage criterion. Although study participants favoured plants with large or colourful flowers, only a third of all plants in the meadows created with real plants were flowering and in people's imagined meadows grasses were frequently included, indicating that people like diverse meadows consisting of a green matrix with some colourful flowers. 相似文献
