多污染源随机排污的水质影响分析方法及其应用

针对污水排放特征,将污染源分为连续排放型污染源和间隙排放型污染源。对连续排放型污染源,采用确定性方法定义污染源强;而对于间隙排放型污染源,运用不确定性理论,根据其排放污染源的随机统计特征,对污染源进行随机概化。将不确定性理论应用于多污染源随机排污对环境水体的水质影响分析,给出了基于不确定性理论的水质影响预测方法,建立了二维随机水质数学模型。并将该方法应用于某市水源地水质影响的随机分析,得到了在多污染源随机排放协同影响下水质浓度随机变化的统计特征。

Task analysis training of case managers to assist seriously mentally ill patients find roommates and housing

This study examined the efficacy of task analysis training for case managers helping seriously mentally ill patients find roommates and housing. Behavioral objectives and task analysis were used to develop the task-oriented behavioral training program. Case managers were trained to use a checklist for every session with patients, which included the goal of the session, tasks required to accomplish that goal and lists of all the sub-tasks. The results of this study suggest that this methodology: (1) reduced the time required for patients to find roommates and housing; (2) increased the percentage of patients finding housing; and (3) decreased hospitalization rates occurring during the process of looking for roommates and housing.

ID-based threshold decryption secure against adaptive chosen-ciphertext attack

This paper proposes an identity-based threshold decryption scheme IB-ThDec and reduces its security to the Bilinear Diffie-Hellman problem. Compared with previous work, this conceals two pairing computations in the ciphertext validity verification procedure. The formal proof of security of this scheme is provided in the random oracle model. Additionally, we show that IB-ThDec can be applied to the threshold key escrow and the mediated cryptosystems.     

噻二唑二聚物/丁氧基三乙二醇复合物的合成

合成了噻二唑二聚物/丁氧基三乙二醇复合物。反应物的摩尔比及反应温度影响产物作为添加剂加入到润滑脂中的抗烧结性能。在最佳反应条件下,即n(噻二唑二聚物)∶n(丁氧基三乙二醇)=0.5∶1.0,反应温度125℃时,产率为85%。通过分子模拟、红外光谱、13C核磁共振及N、S元素的含量测定,探讨了产物的结构及反应机理。结果表明,噻二唑二聚物与丁氧基三乙二醇的摩尔比越大,在金属表面形成配位的噻二唑环的个数就越多,就会表现出更强的吸附特性,从而表现出更高的抗烧结性能。
