Novel management interventions intended to mitigate the impacts of climate change on biodiversity are increasingly being considered by scientists and practitioners. However, resistance to more transformative interventions remains common across both specialist and lay communities and is generally assumed to be strongly entrenched. We used a decision-pathways survey of the public in Canada and the United States (n = 1490) to test two propositions relating to climate-motivated interventions for conservation: most public groups are uncomfortable with interventionist options for conserving biodiversity and given the strong values basis for preferences regarding biodiversity and natural systems more broadly, people are unlikely to change their minds. Our pathways design tested and retested levels of comfort with interventions for forest ecosystems at three different points in the survey. Comfort was reexamined given different nudges (including new information from trusted experts) and in reference to a particular species (bristlecone pine [Pinus longaeva]). In contrast with expectations of public unease, baseline levels of public comfort with climate interventions in forests was moderately high (46% comfortable) and increased further when respondents were given new information and the opportunity to change their choice after consideration of a particular species. People who were initially comfortable with interventions tended to remain so (79%), whereas 42% of those who were initially uncomfortable and 40% of those who were uncertain shifted to comfortable by the end of the survey. In short and across questions, comfort levels with interventions were high, and where discomfort or uncertainty existed, such positions did not appear to be strongly held. We argue that a new decision logic, one based on anthropogenic responsibility, is beginning to replace a default reluctance to intervene with nature. 相似文献

To solve the recycling challenge for aqueous binder based lithium-ion batteries (LIBs), a novel process for recycling and resynthesizing LiNi1/3Co1/3Mn1/3O2 from the cathode scraps generated during manufacturing process is proposed in this study. Trifluoroacetic acid (TFA) is employed to separate the cathode material from the aluminum foil. The effects of TFA concentration, liquid/solid (L/S) ratio, reaction temperature and time on the separation efficiencies of the cathode material and aluminum foil are investigated systematically. The cathode material can be separated completely under the optimal experimental condition of 15 vol.% TFA solution, L/S ratio of 8.0 mL g?1, reacting at 40 °C for 180 min along with appropriate agitation. LiNi1/3Co1/3Mn1/3O2 is successfully resynthesized from the separated cathode material by solid state reaction method. Several kinds of characterizations are performed to verify the typical properties of the resynthesized LiNi1/3Co1/3Mn1/3O2 powder. Electrochemical tests show that the initial charge and discharge capacities of the resynthesized LiNi1/3Co1/3Mn1/3O2 are 201 mAh g?1 and 155.4 mAh g?1 (2.8–4.5 V, 0.1 C), respectively. The discharge capacity remains at 129 mAh g?1 even after 30 cycles with a capacity retention ratio of 83.01%. 相似文献

The Naaf River estuary is one of the large estuaries in the Bangladesh coastal region not to have been affected by extensive
human disturbance. This research provides information about the fisheries diversity status by Estuarine Set Bag Net (ESBN)
sampling relation to physicochemical variables in both spatio-temporal scales. About 25 km of the lower estuary was divided
into six zones for sample collection by considering the accessibility and availability of the ESBN operation, fish landing
centers and location of the fishing villages. In total 48 samples have been analyzed which were taken throughout March to
October 2006. To quantify the species diversity, all fisheries data were analyzed by using EstimateS and EcoSim software which
accounts the different diversity indices viz., species richness, Shannon–Wiener diversity Index, Dominance and Evenness index.
The research results demonstrate that the Naaf River estuary is a habitat of 161 (species richness, Sobs = 161, Choa 1 = 162 ± 2.34,
ACE = 161.73) different species which belong to 98 fin fishes, 23 shrimps and prawns, 13 crabs, 11 molluscs, 3 echinoderms,
4 other crustaceans; while 9 remain unidentified. Results on the aquatic environment, mainly salinity and turbidity were found
to have a major influence on their occurrence and distribution. All the findings indicated that the Naaf River estuary is
a highly productive system and provides a favourable environment for large variety of estuarine species assemblages. 相似文献

High-surface-area mesoprous powders of γ-Al2O3 doped with Cu2+, Cr3+, and V3+ions were prepared via a modified sol–gel method and were investigated as catalysts for the oxidation of chlorinated organic compounds. The composites retained high surface areas and pore volumes comparable with those of undoped γ-Al2O3 and the presence of the transition metal ions enhanced their surface acidic properties. The catalytic activity of the prepared catalysts in the oxidation of 1,2-dichloroethane(DCE) was studied in the temperature range of 250–400°C. The catalytic activity and product selectivity were strongly dependent on the presence and the type of dopant ion. While Cu2+- and Cr3+-containing catalysts showed100% conversion at 300°C and 350°C, V3+-containing catalyst showed considerably lower conversion. Furthermore, while the major products of the reactions over γ-alumina were vinyl chloride(C2H3Cl) and hydrogen chloride(HCl) at all temperatures, Cu- and Cr-doped catalysts showed significantly stronger capability for deep oxidation to CO2. 相似文献

Biomineralization, biosilicification in particular (i.e. the formation of biogenic silica, SiO2), has become an exciting source of inspiration for the development of novel bionic approaches following “nature as model”.
Siliceous sponges are unique among silica forming organisms in their ability to catalyze silica formation using a specific
enzyme termed silicatein. In this study, we review the present state of knowledge on silicatein-mediated “biosilica” formation
in marine sponges, the involvement of further molecules in silica metabolism and their potential application in nanobiotechnology
and medicine.
Werner E. G. Müller dedicated this study to Prof. Vera Gamulin (Rudjer Boskovic Institute, Zagreb, Croatia) in honour of her
unique contributions in molecular evolution. 相似文献

Social and health issues are now considered as an integral part of waste management system. Scavengers or waste pickers are the main victims in waste management sector. Objective of the cross sectional study carried out for a group of scavengers living in huts was to highlight the socio-demographic characteristic, working conditions and occupational health risks with main emphasis on relation of infectious disease prevalence and waste picking activity in Bahawalpur area. Of the 100 waste pickers and 100 non-waste pickers HIV was not detected in any participant, HBV was detected in 4 and 2 % and HCV in 28 and 6 % respectively. Considerable differences were observed in the detection rates of HCV (OR: 6.09, 95 % CI 2.4, 15.5; p = 0.000) and either markers (OR: 5.4, 95 % CI 2.35, 12.5; p = 0.000) in waste pickers compared to general population. The higher incidence of Hepatitis among waste pickers compared to non waste pickers is a function of their occupation, unhygienic living conditions, lack of immunization, ignorance and need of training regarding waste handling. 相似文献
