Use of on-line databases by faculty members and research scholars of Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), New Delhi (India): A survey

The study is focused on finding out the level of use of on-line databases by faculty members and research scholars of the Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), Delhi (India). Both are Central Universities and are funded by the University Grants Commission (UGC). A well-structured questionnaire was administered to faculty members and research scholars of the JNU and JMI to collect data regarding the use of on-line database. The survey reveals that all of the faculty members and research scholars are aware of the availability of on-line databases and largely use them for reference purposes in their research work and studies. The degree of usefulness and utilization of on-line databases is high among the universities' faculty members and research scholars. The survey further reveals that the respondents from both universities are aware of the search options for accessing on-line databases. It is also found that a large number of respondents of JNU and JMI are using field searching and Boolean operators to access information from on-line databases.     

铅污染对青紫泥田土壤中苄嘧磺隆降解的影响

在实验室培养条件下,研究了Pb对苄嘧磺隆除草剂在青紫泥田土壤中的残留和消失动态.结果表明Pb抑制了土壤中苄嘧磺隆的降解,使残留量提高、消失率降低.至培养结束(第180天)时,不同Pb浓度处理下土壤中的残留量在0.18～0.57 mg.kg-1之间,消失率在91%～97%之间.苄嘧磺隆降解随培养时间的变化符合一级反应动力学方程.降解半衰期N33.2～57.2天.分析表明,300 mg·kg-1可能是Pb严重抑制苄嘧磺隆降解的临界浓度,而500 mg·kg-1则可能是Pb强烈抑制苄嘧磺隆降解的上限浓度.上述结果对制定土壤环境重金属容量标准具有较好的参考意义.
