Open Journal of Psychiatry 2024年第S2期14卷 514-527页

Background: Transcranial direct current stimulation (tDCS) has research evidence that it can reduce symptoms of depression. Flow FL-100 is a transcranial direct current stimulation (tDCS) device self-administered by a patient at home in combination with a software application that delivers wellbeing behaviour therapy training. Purpose/aim: The purpose of this study was to investigate if Flow can be introduced to a Crisis Resolution & Home Treatment (CRT) service and the impact of Flow in treating depression. The study addresses the questions: 1) “what are the depression reliable improvement and remission rates?” and 2) “can Flow significantly reduce depressive symptoms and improve real world functioning (every-day, social and occupational functioning) and health-related quality of life?”. Methods: An open-label patient cohort design with no control group. Pre-intervention and 6-week follow-up intervention assessments using the participant self-report measures: Patient Health Questionnaire (PHQ-9), Work and Social Adjustment Scale (WSAS), and EuroQol five-dimension (EQ-5D-5L). Participants were 49 CRT patients, 19 males and 30 females, with an age range of 20 to 66 years, and average age of 42 years. Results: PHQ-9 reliable improvement and remission rates were 57.1% and 14.3%. PHQ-9 scores significantly improved, from 23.1 (SD 3.44) to 14.8 (SD 6.82) at 6 weeks, with a large effect size. PHQ-9 suicide/self-harm related question significantly improved from 2.51 (SD 0.77) to 1.08 (SD 1.17), with a large effect size. WSAS scores significantly improved, from 33.6 (SD 5.22) to 21.9 (SD 10.82) at 6 weeks, with a large effect size. EQ-5D-5L results showed significant improvements in the health index score, global assessment of health EQ-VAS from 34.2 (22.26) to 51.6 (24.95), and three EQ-5D-5L dimensions (“self-care”, “usual activity”, and “anxiety/depression”). Conclusion: A CRT service effectively integrated Flow tDCS treatment. Flow was beneficial in terms of improving f

Journal of Energy and Power Engineering 2017年第7期11卷 439-445页

作者： Shane Colelough Neil J. Hewitt Philip griffiths Centre for Sustainable Technologies 26 B 16 Ulster University Newtownabbey BT37 OQB Northern Ireland UK

The financial viability of a solar STES （seasonal thermal energy store） installed in a mixed commercial and residential multiunit development of low-energy buildings located in Lysekil, Sweden, a maritime Scandinavian Climate has been investigated. Using recorded figures for the installation costs and performance, a financial life cycle analysis has been undertaken to determine the cost effectiveness of the system. The time value of money is considered and an LCC （life cycle cost） analysis undertaken to identify the cost-effectiveness of the solution. It shows that while a direct heating and hot water system incorporating STES can be economically viable in a Swedish maritime climate in the long term, assistance such as that provided by government incentives is required to assist with the high capital cost of the initial investment.

一、微型信息处理机控制的电阻率横断面系统(MRT)MRT系统是有效的电阻率成象系统。此系统的设计可以提供信息,从而确定沿剖面上横截面的地下岩层电阻率分布。在地层显示出侧向和垂直向两个方向电性变化的地方,这个系统特别有用。野外技术包括沿给定剖面上反复做等间距视电阻率的横向测线测量,并且每做一次增加一次极间距。用这种办法建立电阻率空间剖面——拟剖面,从而以等值线来提供地下岩层电阻率分布的定性图象。在地下岩层是二维结构并且某些约束条件是可用的地区。

采用两种孔径的尼龙网袋(1mm和5μm),将盆钵供试土壤分成内外两层,内层土壤混合猪粪或稻草,并以不添加猪粪和稻草的供试土壤作为空白;外层直接接入供试土壤,进行培养,以获取土著食细菌线虫大量富集的试验土壤。结果表明:添加基质(猪粪和稻草)显著地促进了土壤线虫的繁殖,大量繁殖的线虫通过1mm网袋迁移至外层未加基质的土壤,而采用5μm网袋则限制了线虫向外层土壤的迁移。添加猪粪的1mm网袋处理经过28d培养后,外层土壤线虫数是空白处理的9.1倍;添加稻草的1mm网袋处理经过35d培养后,外层土壤线虫数是空白处理的5.9倍。添加两种基质的5μm网袋处理,外层土壤线虫数和空白处理差异不大。添加基质主要是促进了食细菌线虫的繁殖,在培养结束时,添加猪粪的1mm网袋处理的食细菌线虫比例达到98.2%,添加稻草的1mm网袋处理的食细菌线虫比例达到90.5%,两个处理食细菌线虫的总数分别是空白处理的14.8倍和8.9倍,并且主要是Protorhabditis sp.线虫的增加。
