Increased temperatures from global climate change are projected to cause substantial losses in crop productivity by the end of the twenty-first century. High temperature is predominant among the cardinal ecological factors that determine crop growth and productivity (Al-Khatib and Paulsen, 1999). In cotton, temperature is a primary controller of the rate of plant growth, developmental events, a...

Abiotic stress accounts for a large proportion of total harvest yield losses every year. Like any plant, cotton must adapt accordingly to the conditions at hand and likewise mitigate possible future effects. High-temperature stress is commonly experienced across the Mississippi river delta regions of Arkansas multiple times during the season. Higher temperatures above a critical threshold do ge...

In this letter, the characteristics of positive bias temperature instability (PBTI) and hot carrier stress (HCS) for the lowtemperature poly-Si thin-film transistors (LTPS-TFTs) with HfO2 gate dielectric are well investigated for the first time. Under room temperature stress condition, the PBTI shows a more serious degradation than does HCS, indicating that the gate bias stress would dominate t...

Some cucurbit plants (Cucumis sativus L., Cucurbita pepo Cucumis melo L. and Citrillus lanatus L.) were used for investigating some physiological changes protein patterns under heat stress in plants. Leaf samples exposed tohigh temperatures as follows 35, 40, 45, 50, 55 60°C. Percentage of ion leakage, chlorophyll content, leaf relative water content (RWC) loss turgidity, total soluble (TSP) pr...
