Evaluation of a Wireless solar Powered Personal Weather station

Agricultural sciences 2024年第1期15卷 36-53页

作者： Robert J. Lascano Timothy s. Goebel Dennis C. Gitz III john E. stout Cropping systems Research Laboratory Wind Erosion and Water Conservation Research Unit USDA-ARS Lubbock TX USA

We are evaluating dryland cotton production in Martin County, Texas, measuring cotton lint yield per unit of rainfall. Our goal is to collect rainfall data per 250 - 400 ha. Upon selection of a rainfall gauge, we realized that the cost of using, for example, a tipping bucket-type rain gauge would be too expensive and thus searched for an alternative method. We selected an all-in-one commercially available weather station;hereafter, referred to as a Personal Weather station (PWs) that is both wireless and solar powered. Our objective was to evaluate average measurements of rainfall obtained with the PWs and to compare these to measurements obtained with an automatic weather station (AWs). For this purpose, we installed four PWs deployed within 20 m of the Plant stress and Water Conservation Meteorological Tower that was used as our AWs, located at UsDA-ARs Cropping systems Research Laboratory, Lubbock, TX. In addition, we measured and compared hourly average values of short-wave irradiance (Rsub>gsub>), air temperature (Tsub>airsub>) and relative humidity (RH), and wind speed (Ws), and calculated values of dewpoint temperature (Tsub>dewsub>). This comparison was done over a 242-day period (1 October 2022-31 May 2023) and results indicated that there was no statistical difference in measurements of rainfall between the PWs and AWs. Hourly average values of Rsub>gsub> measured with the PWs and AWs agreed on clear days, but PWs measurements were higher on cloudy days. There was no statistical difference between PWs and AWs hourly average measurements of Tsub>airsub>, RH, and calculated Tsub>dewsub>. Hourly average measurements of Rsub>gsub> and Ws were more variable. We concluded that the PWs we selected will provide adequate values of rainfall and other weather variables to meet our goal of evaluating dryland cotton lint yield per unit rainfall.

Brain Research on Mental Disorders: A Criticism

引用

Open Journal of Medical Psychology 2024年第3期13卷 71-85页

作者： john R. Rossiter Faculty of Business and Law University of Wollongong Wollongong Australia school of Psychology Charles Sturt University Wagga Wagga Australia

Objective: To expose the problems and inherent limitations of neuroscience-based brain research on mental disorders. Method: Discussion of the theory underlying brain research on mental disorders, followed by a systematic evaluation of typical studies. Results: The fundamental problem is that brain researchers fail to differentiate between biological mental disorders in which brain processes cause the disorder (notably schizophrenia, bipolar disorder, and melancholic depression) and learned mental disorders in which brain processes mediate but do not cause the disorder (which is the case with reactive depression, reactive anxiety, OCD, and PTsD). Researchers have been unsuccessful in identifying mechanisms in the brain that cause biological mental disorders, and will never be able to locate the innumerable specific neural connections that mediate learned mental disorders. Moreover, the author’s review of typical studies in this field shows that they have serious problems with theory, measurement, and data analysis, and that their findings cannot be trusted. Conclusions: Neuroscience-based brain research on mental disorders, unlike other neurological research, has been an expensive failure and it is not worth continuing.

黄土高原黄土-古土壤序列中保存有丰富的土壤碳酸盐,是利用碳酸盐团簇同位素(Δ_(47))定量重建古温度的重要地质载体之一。然而,黄土高原全新世土壤碳酸盐Δ_(47)及其气候指示意义的系统研究仍然缺乏。本研究分析了黄土高原南缘渭南剖面和中部洛川剖面上部3 m沉积中保存的全新世土壤碳酸盐(钙结核)的团簇同位素组成,监测了现在地形条件下距地表4 m以内不同深度的土壤温度。结果显示,Δ_(47)定量重建的全新世土壤碳酸盐团簇同位素温度(T_(47))与现代暖季节温度相近,渭南剖面T_(47)平均值约为25℃,洛川剖面约为18℃,较区域年均温高8~10℃。根据T_(47)和土壤碳酸盐氧同位素组成(δ18O)重建的土壤水δ18O也与暖季节降水的δ18O基本一致,这些数据表明黄土高原土壤碳酸盐记录了暖季节的环境信息。值得注意的是,渭南和洛川剖面钙结核T_(47)值与其形成深度的土壤温度基本吻合,结合前人研究结果,这暗示了土壤碳酸盐形成深度对其T_(47)具有显著影响。因此,在将来土壤碳酸盐Δ_(47)的研究中,评估土壤碳酸盐形成深度至关重要。
