A diode works for battery charging, as shown in Figure 1 . When we use an RF source excitation, the wiring inductance L matters. Let us consider how affects turn-on and -off operation. The voltage xmlns:xlink="htt...

Under the synergetic effect of land use and climate change, natural disasters occur frequently in karst region southwest China. This study used daily precipitation data from 33 meteorological stations across 61 years (1960–2020), utilized MK test Z index to calculate levels drought waterlogging (DW) at multiple times (month year) spatial (province, sub-divisions, station) scales, investigated s...

Selection of drought tolerant wheat genotypes for Arid and Semi-arid lands (ASALS) of Kenya, which consist of 83% of total land area, can provide alternative agricultural land for expansion. To reduce cost of dryland research, simulated drought under a rain shelter offers a good alternative for screening because marginal areas are vast and widespread. Four moisture regimes which simulated termi...

Groundwater drought is a natural hazard that develops when groundwater systems are affected by climatical drought, when climatical drought occures, first groundwater recharge, later groundwater levels and groundwater discharge decrease. The origin of drought is a deficit in precipitation and that takes place in all the elements that comprise the hydrological cycle (flow in the rivers, soil mois...

Prolonged drought stress combined with high leaf temperatures can induce programmed leaf senescence involving lipid peroxidation, and the loss of net carbon assimilation during early stages of tree mortality. Periodic droughts are known to induce widespread tree mortality in the Amazon rainforest, but little is known about the role of lipid peroxidation during drought-induced leaf senescence. I...

Abstract. The term “flash drought” describes a type of drought with rapid onset and strong intensity, which is co-affected by both water-limited energy-limited conditions. It has aroused widespread attention in related research communities due to its devastating impacts on agricultural production natural systems. Based global reanalysis dataset, we identify flash droughts across China during 19...

Drought is a major problematic phenomenon mostly for semi-arid areas of Iran. During drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. Therefore, the assessment of drought effects on plant covers is the most important issue. This research was conducted in 2015 using the extracted vegetation indices from Moderate Resolution Ima...

General comments In this study, the authors use an extensive dataset of predawn water potentials of 6 species over 10 years, which included a severe drought and several moderate ones, to examine potential predictors in cross-species patterns of mortality. I found this study to be very interesting and insightful. Such datasets of plant water potential, especially those that span many years, many...
