Photocatalytic degradation of Bisphenol A (BPA), a representative endocrine disruptor chemical, was carried out under irradiation of sunlight in the presence of CexZn1-xO nanophotocatalyst. Cerium (Ce) ions were successfully incorporated into the bulk lattice of ZnO by simple co-precipitation process. The CexZn1-xO composite nanostructures exhibited higher photocatalytic efficiency than pure ZnO in the degradation of BPA under sunlight irradiation and nearly complete mineralization of BPA was achieved. The degradation rate was strongly dependent on factors such as the size and structure of catalyst, doping material concentration, BPA concentration, catalyst load, irradiation time and pH levels. This work suggested that the CexZn1-xO assisted photocatalytic degradation is a versatile, economic, environmentally benign and efficient method for BPA removal in the aqueous environment. 相似文献

This paper examined the factors that might influence participating farmers’ willingness-to-pay for the Tree Farming Fund (TFF)
established for sustainable development of participatory forest management (PFM). Information on willingness-to-pay, socioeconomic
characteristics, and attitudes of participating farmers toward TFF were obtained from interviews with 581 participating farmers.
Logistic regression analysis was used to determine the dominant factors that might influence participating farmers’ willingness-to-pay
for the TFF. The results showed that participating farmers’ willingness-to-pay was significantly affected by (i) family income;
(ii) education level; (iii) confidence that his aspired benefits will be received; (iv) agreement with the statement that
‘PFM is sustainable under the present state of management’; (v) agreement with the statement that ‘PFM is a good strategy
for forest conservation’; and (vi) knowledge of PFM strategies. Thus, participating farmers with a higher level of education,
higher income and positive attitudes toward TFF tended to express more willingness-to-pay. Establishment of TFF could be an
effective strategy in implementing sustainable PFM in Bangladesh. For this strategy to succeed, however, active partnership
between the participating farmers and Forest Department is required. Participating farmers’ attitudes toward TFF should therefore
be taken into consideration as should the results of this study, which are important indicators of participating farmers’
positive attitudes toward TFF. 相似文献

Sustainability in forestry is a complex amalgam of trade-offs among its various dimensions and there is no easy route to achieve sustainable development. It is important that policy process and implementation strategy of these policies should be based on sound information about these trade-offs. There is a growing consensus amongst key forest decision-makers in Bangladesh that traditional forestry is needed to make the transition to more sustainable forestry, which is likely to involve local people in forest management. As a result, the government has initiated a social forestry program from 1981 with the assistance of the Asian Development Bank (ADB) loan and the United Nations Development Program (UNDP) grant and operated mainly in Sal forest areas. The most important objective of this program is to protect, manage, and develop forests in a sustainable way by involving local communities. Although several studies have focused on the management issues of social forestry, none of these studies has evaluated the indicators of sustainable social forestry. The purpose of this study is to evaluate the criteria of sustainable development of social forestry in Bangladesh. The study is based on primary cross-sectional data collected using the multistage stratified sampling technique. In total, 581 social forestry farmers were selected randomly and interviewed using a pre-tested questionnaire. The study evaluated some important components of sustainable development and identified the following conditions of social forestry in Bangladesh:(i) almost all the components of sustainable development of social forestry, although not at the aspiration level, were at good condition;(ii) participants were interested and committed to work with Forest Department in developing social forestry;(iii) they had been utilizing both hard and soft technology in practicing social forestry, although there exists ample scope of development;(iv) income of participants after involving in social forestry had increased, although not at satisfactory level; and(v) process of producing social and material goods had been under progress.However, there exist plenty of scopes for sustainable social forestry development through improving the sustainable development components more carefully.Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue. 相似文献

We report a case in which mosaicism of trisomy 13 was detected in 4/10 cells (40 per cent) in amniotic fluid cell cultures, followed by a low rate of mosaicism (1/160 cells) detected in a fetal blood sample. This finding presents a dilemma both for the genetic counsellor and for the parents in determining whether or not to terminate the pregnancy. 相似文献

India is one of the most populous countries and is the third largest greenhouse gas–emitting nation. Energy security is a serious issue for India as it relies heavily on fossil fuel imports. Biodiesel production using microalgae as feedstock can address both of these issues. In this study, the technical feasibility of microalgae‐based biodiesel production is carried out for a coal thermal power plant (i.e., Budge Budge Thermal Station) in the state of West Bengal, India, using a generic methodology. An oleaginous microalgae species that is tolerant toward flue gas was identified (i.e., Nannochloropsis sp). A 75‐acre open raceway microalgae production plant was designed keeping the costs, energy demand, and CO2 emissions low. The open raceway pond can use 38 tons of CO2, produce 19 tons of algal biomass, and treat 9320 m3 of wastewater per acre annually. 相似文献

Biofuel blends produced from Jatropha (Jatropha curcas) and Karanja (Pongamia pinnata) oil were evaluated for their combustion properties. Two kinds of blends (regular diesel with Jatropha and Karanja oil) were prepared at 20% volume to the diesel and tested as alternative fuels in single cylinder (vertical), water-cooled, direct injection diesel engine at the rated speed of 1500 rpm. The performance of the engine in terms of thermal efficiency at full load for diesel was 30%. For Jatropha and Karanja biodiesel blends, the thermal efficiencies were 29.0% and 28.6%, respectively. The maximum cylinder pressure and ignition delay for biodiesel fuel blends are very close to that of regular diesel. Prolonged combustion was observed for Karanja oil blend in comparison to Jatropha oil blend. The combustion pattern also reveals the slow burning characteristics of vegetable oils and this study indicates that the blended biofuels have combustion characteristics that are similar to regular diesel fuels. 相似文献
