An ultrastructural study has been made to determine to what degree chloroplast differentiation is retarded in leaves of young jack bean (Canavalia ensiformis [L.] DC.) seedlings when they are subjected to mild water stress. Rapid chloroplast differentiation occurred when etiolated seedlings were allowed to green at relative humidities above 85% but not at a relative humidity of 25%. Response to...

Plastic responses to heat and desiccation stress in insects have been studied in many laboratory experiments on Drosophila. However, in these studies the possible interaction between the corresponding stress factors in natural environments has not been taken into consideration. We investigated changes in heat and desiccation resistance of adult Drosophila simulans after short-term exposures to ...

An increase in average air temperature and frequency of rain events is predicted for higher latitudes by the end of the 21st century, accompanied by a probable rise in air humidity. We currently lack knowledge on how forest trees acclimate to rising air humidity in temperate climates. We analysed the leaf gas exchange, sap flow and growth characteristics of hybrid aspen (Populus tremula × P. tr...

It is vital to evaluate the volume of the absorbing capacity and the amount of bleeding during endoscopic surgery. However, the monitoring equipment has been blank because of the monitoring methods applied currently have their inborn deficiency. The aim of this project is to design an intelligent system to monitor irrigating fluid absorption and blood loss in the endoscopic surgery rapidly and ...

Turmeric varieties viz., Rajendrasonia and Pitamber were subjected to water stress by irrigating at different intervals. Impact of on morphological, physiological yield parameters both the investigated. In this study irrigation treatments divided into three groups. Group A, control receives weekly once. For every two weeks once group B was irrigated for C irrigated. Plants which are under heavy...

[1] Simulations of warming climates with coupled climate models exhibit strong land-ocean contrasts in changes in surface temperature and relative humidity, but little land-ocean contrast in changes in equivalent potential temperature. A theory that assumes equal changes in equivalent potential temperature over land and ocean captures the simulated land-ocean warming contrast in the tropics if ...

introduction in recent years, rainfall deficiency was an increasing problem in most countries; which limited the production of agricultural crops. among abiotic stresses the plants encountered, drought stress is considered as the most important limiting factor in plants growth and reproduction in natural and agricultural systems through most parts of the world; while drought stress causes 45% i...

Temperature and relative humidity have opposing effects on evaporative water loss, the likely mediator of the temperature-dependence of nephrolithiasis. However, prior studies considered only dry-bulb temperatures when estimating the temperature-dependence of nephrolithiasis. We used distributed lag non-linear models and repeated 10-fold cross-validation to determine the daily temperature metri...
