Assessment of global solar resource development

With the increasing severity of environmental problems, many countries have set energy transition targets to promote the realization of the Paris Agreement. There has been a global consensus on utilizing solar energy resources as alternatives to conventional sources to support this energy transition. In this regard, analyzing the “location,” “quantity,” and “quality” of global solar energy resources will not only assist an individual country to efficiently utilize these resources but also promote the realization of large-scale intercontinental resource utilization and complementation. This study established the basic database, model methods, and platform tools for global solar energy assessment, Then, a global solar energy resource assessment was conducted, which included the theoretical reserves (TRs), technical installed potential capacity (TPIC), and average development cost (ADC). A comparative analysis of the assessment results for all continents was also performed. After that, based on big data analysis and geographic information system (GIS) calculations, the distribution characteristics of the global solar power TPIC were calculated with the two core indicators, namely the capacity factor and ADC. Furthermore, a data-driven quantitative evaluation of the refined development potential of solar energy resources was performed. Finally, the reasonableness and coincidence analysis of the resource assessment results were verified using data from global and specifically Chinese photovoltaic (PV) bases.

Reproductive and neurobehavioural effects of thiabendazole administered to mice in the diet

Thiabendazole was given in the diet to provide levels of 0 (control), 0.031, 0.125, and 0.5% from 5 weeks of age of the F₀ generation to 9 weeks of age of the F₁ generation in mice, and selected reproductive and neurobehavioural parameters were measured. The average litter size and weight were significantly reduced in the high-dose group at birth. No adverse effects were observed in the sex ratio at birth. The average body weight of offspring was significantly increased in the low-dose group during the late lactation period, and was significantly reduced in the high-dose group during the lactation period. In the assessment of neurobehavioural parameters, surface righting at postnatal day (PND) 7 was significantly delayed in a dose-related manner in both sexes. Swimming limb movement at PND 14 and olfactory orientation at PND 14 were significantly depressed in the high-dose group in both sexes. In movement activity at 3 weeks of age in the F₁ generation, vertical time and number of defaecations were significantly decreased in the high-dose group in female offspring. Several adverse effects on reproductive and neurobehavioural parameters were produced at the highest dose level of thiabendazole used in the present study (equivalent to 700-1800mg/kg bw/day). Slight, dose-related delays were also seen in surface-righting ability at the two lower dose levels. The lowest dose level (equivalent to 50-180mg/kg bw/day) is 500
