应用10-12s级时间分辨率的荧光光谱,测定了两种碳菁染料和一种荧光素染料（四碘荧光素B）的荧光寿命τ与溶剂粘度η之间的函数关系,发现碳菁染料在二元醇和丙三醇中的τFM低得反常.在二元醇溶剂中,它们的τFM与溶剂粘度η2/3呈线性函数关系,但在一元醇溶剂中则并无此线性关系.由此可见,在研究染料分子的寿命与由不同系列醇（例如乙醇和丙三醇）组成的混合溶剂的粘度之间的依赖关系时,必须十分谨慎.对于四碘荧光素B,它在一元醇中的荧光寿命与溶剂粘度的关系符合2/3指数规律.

阔草脲和禾草灵对小麦养分吸收的影响

通过大田和温室试验，研究了除草剂阔草脲和禾草灵对小麦养分吸收和利用的影响。在温室，施用阔草脲使小麦地上部重量、根重和根长下降。阔草脲使小麦吸磷减少，尤其是在低磷供应的情况下，减少更明显；同时钾的吸收也减少，氮、钙、镁的吸收不受影响。在大田试验中，阔草脲使小麦生长早期的地上部植株几种元素的浓度降低达30％。该效应随小麦生长期的进展而减弱。阔草脲对成熟籽粒的养分浓度和籽粒产量没有影响。几种元素对施用阔草脲敏感的顺序如下：大量元素：P、K＞N、S＞Ca、Mg，微量元素：Zn、Cu＞Mn＞Fe。不同品种对阔草脲的敏感程度存在差异，如品种Kulin比Reeves敏感。施用禾草灵对小麦地上部养分浓度的影响很小。Zn和Cu的浓度在营养生长时减少，Kulin的成熟籽粒仅Cu的浓度减少。除草剂使主要通过扩散到达根部养分吸收的减少量大于主要通过质流到达根部的养分吸收减少量。除草剂的施用极可能改变了根下扎土壤的能力，但对根表的吸收影响较小。

Length of stay in treatment is thought to be the best predictors for long-term recovery from substance use disorders. The objective of this study was to examine the relationship between participation in mind-body-spirit (MBS) therapeutic programs and length of stay in a residential treatment facility. A retrospective analysis of data from 1719 subjects who were admitted to a 30-day residential program for substance use disorders (SUD) was conducted. Subjects participated in MBS programs that included yoga, acupuncture and meditation. We examined the effects of subject participation in MBS programs for subjects who left against staff advice (ASA) and those who successfully completed the residential program. A higher percentage of subjects with severe heroin use disorder left ASA compared with subjects with severe alcohol use disorder (16% vs. 9%, respectively). Most subjects from both substance groups who failed to complete the 30-day treatment program, left within the first two weeks of stay (59% of alcohol group and 75% of heroin group);however, again, the percentage of heroin users leaving during the first two weeks was significantly greater compared with that of alcohol subjects. We found a highly significant, positive correlation (r = 0.56, p < 0.01) and a statistically significant increase in LOS for all subjects, regardless of the substance type, and the number of MBS program sessions attended showing an association between MBS participation and increased LOS. These data support the inclusion of MBS programs as part of a comprehensive treatment strategy for SUD in combination with traditional counseling to help develop a sustainable long-term recovery.

Journal of Water Resource and Protection 2020年第7期12卷 618-635页

In Kuwait, dairy farming faces challenges due to its significant water demands. The current study assessed seasonal patterns of water use to estimate the blue water footprint (WF) and grey WF per kg of fat protein corrected milk (FPCM) for confined dairy farming systems in Kuwait. Blue and grey WFs were evaluated using data from three operational farms. The average blue WF (L·kg-1 FPCM) was estimated to be 54.5 ± 4.0 L·kg-1 in summer and 19.2 ± 0.8 L·kg-1 in winter. The average grey WF (generated from milk house wastewater) was assessed on bimonthly basis and determined based on its phosphate (PO4) concentration (82.2 ± 14.3 mg·L-1) which is the most limiting factor to be 23.0 ± 9.0 L·kg-1 FPCM d-1. The outcomes indicate that enhancing the performance of dairy cows and adopting alternative water management strategies can play a role in minimizing the impacts of confined dairy farming systems in Kuwait on water quality and quantity.
