酸碱对剩余活性污泥中氮磷类物质破解研究

污水处理过程中产生的剩余活性污泥量大,难以被处理处置,目前已成为污水厂自身的严重污染源。用不同浓度的HCl溶液、NaOH溶液分别对城市污水厂剩余活性污泥进行处理后,对其中溶解性氮、磷物质的破解释放规律进行了对比研究。实验结果表明,在泥水体积比相同的条件下,同浓度NaOH溶液对污泥NH4＋－N的释放效果好于HCl溶液,但对溶解性PO43－－P的释放质量浓度低于HCl溶液;两种方法中NH4＋－N的最大释放质量浓度分别是106．0、153．4 mg/L ,PO43－－P的释放质量浓度分别是133．5、126．3 mg/L。研究为进一步污泥资源化应用提供了理论依据。     

甘肃张掖地区农村冠心病患者二级预防用药调查分析

目的:探讨甘肃张掖地区农村冠心病(CHD)患者二级预防用药现状及影响因素,为提高CHD患者二级预防药物的使用率与服药依从性提供参考依据;方法:选择甘肃张掖市及各县区范围内农村CHD患者327人,在患者就诊时通过访谈填写统一的调查表,分析二级预防药物的使用率、服药依从性以及影响因素,并与289名城镇患者进行比较;结果:农村CHD患者抗血小板药、β-受体阻滞剂、他汀类、ACEI/ARB的服药率分别为81.7%、41.9%、34.3%、37.9%;联合用药中二联、三联、四联用药分别为占50.2%、16.5%、7.0%,均低于本地区城市CHD患者;93.0%患者服药依从性较差,对CHD药物预防认识不足,服药随意性强是影响服药依从性的主要原因.结论:张掖地区农村CHD患者二级预防药物的使用与指南要求有很大差距,应提高基层医师和CHD患者对二级预防药物益处的认识,提高药物的使用率与服药依从性.     

基于最小二乘支持向量机算法的小地锚抗拔承载力研究

目的：基于最小二乘支持向量机算法预测小地锚的抗拔承载力。方法：最小二乘支持向量机算法中的输入参数包括等效地锚直径,地锚埋置深度,平均顶椎阻力,平均椎套摩擦力以及安装工艺。使用现场试验的119组数据中的83组数据进行最小二乘支持向量机回归模型分析,并使用剩余的36组数据测试模型的拟合良好性;同时用敏感度分析研究每个输入参数的作用。结论：通过与人工神经网络模型的对比,发现最小二乘支持向量机的性能表现优异。     

Effect of fluoxetine on weight reduction in obese patients

Obesity is one of the most important health problems, which many people suffer from it. As a chronic disease, it is a precipitating factor for many medical conditions like hypertension, diabetes mellitus, hyperlipidemia, coronary artery disease, sleep apnea syndrome and some malignancies (breast, uterus, prostate and colon carcinoma). With attention to this fact that obesity is an independent risk factor associated with significant increase in morbidity and mortality, treatment of overweight individuals is very important. One of the medications for short-term weight loss is fluoxetin. In this clinical trial study, fluoxetin effect on weight loss induction during 8 weeks was investigated. 201 cases with BMI between 25–42 were selected randomly (113 female and 88 male) and all received fluoxetine (40 mg daily) for 8 weeks. Measurement was carried out after the 4^th and 8^th week of administration and 4 weeks after end of treatment. Management of 9 cases (4 due to weight gain and 5 due to headache) were discontinued after 4 weeks of treatment. Data assessments were performed using t-test and SPSS program. Mean body weight at first visit was 89.32±13.30kg. At the 4^th, 8^th week of treatment and 4 weeks after study, the mean body weight of cases reached 86.09±13.27 (p=0.00), 82.69±11.31 (p=0.00) and 81.97±13.26 (p=0.00) respectively. Mean BMI at first visit was 34.90±5.20kg/m². At 4^th, 8^th weeks of treatment it was 33.72±5.20kg/m² and 32.40±5.18kg/m² respectively. Mean weight loss at 4^th and 8^th weeks of treatment was 3.24kg and 6.67kg respectively without any weight gain at the end of the 4^th week after discontinuation of the drug. Fluoxetine is an effective, well-tolerated and relatively safe drug for short-term treatment of obesity.

固体废物既是污染物质的源头也是其归宿,其处理处置涉及水、空气及土壤污染。"固体废物处理与处置"课程本身是一门交叉性非常强的专业技术课程,具有内容繁多、理论性强、学时短等特点。本文结合本科课程"固体废物处理与处置"的内容及特点采用案例互动教学方法对教学的具体实施过程、实施效果及需要注意的问题进行具体分析,以提升课程教学内容的丰富度、提高学生实践能力为目标,创建培养人才新模式。     

Investigating the potential of using acoustic frequency on the degradation of linear alkylbenzen sulfonates from aqueous solution

The effectiveness of using acoustical (sonochemical) reactor for degradation of linear alkylbenzen sulfonate (LAS) from aqueous solution was investigated. LASs are anionic surfactants,found in relatively high amounts in domestic and industrial wastewaters. In this study,experiments on LAS solution were performed using methylene blue active substances (MBAS) method. The effectiveness of acoustical processor reactor for LAS degradation is evaluated with emphasis on the effect of treatment time and initial LAS concentration. Experiments were performed at initial concentrations of 0.2,0.5,0.8 and 1.0 mg/L,acoustic fre-quency of 130 kHz,applied power of 500 W and temperature of 18 °C～20 °C. At the conditions involved,LAS degradation was found to increase with increasing sonochemical time. In addition,as the concentration increased,the LAS degradation rate de-creased in the acoustical processor reactor.
