This Master by Research project aims to develop the human gas capsule that enables realtime intestinal gas profiling in a low-cost, non-invasive and accurate manner. The safety, viability, reliability and repeatability of the capsule will be evaluated in both laboratorial environments and animal trials that are influenced by dietary effect, heat-stress-induced gut disorder and dietary supplemental therapeutic agent.

Generating power from renewable biogas in solid oxide fuel cells (SOFCs) is an environment-friendly, efficient, and promising energy conversion process. Biogas can be used in SOFCs via a reforming process for which dry reforming is more suitable as the reforming agent exists in the biogas mixture. Biogas can be directly reformed to H2 -rich fuel stream in the anode chamber of a SOFC by the heat released during power generation.

Regulatory adjustments to acute and chronic temperature changes are highly important for aquatic ectotherms because temperature affects their metabolic rate as well as the already low oxygen concentration in water, which can upset their energy balance.

Lake Baikal is one of the oldest freshwater lakes and has constituted a stable environment for millions of years, in stark contrast to small, transient bodies of water in its immediate vicinity. A highly diverse endemic endemic amphipod fauna is found in one, but not the other habitat. We ask here whether differences in stress response can explain the immiscibility barrier between Lake Baikal and non-Baikal faunas.

Heat stress one of the Environment stress comes under Abiotic stress. Heat stress is the major problem for wheat crops in the current climate whether as a result of increasing global warming. These changes affect negative possessions on crops such, physiological aspects. In that study, there are taken various physiological parameters for twelve wheat genotypes viz DBW17, PBW343, DBW71, DBW16, WH711, RAJ3765, PBW373, PBW502, C306, WH730, PBW233, and WH157.The chlorophyll content and photosynthetic rate, decrease in high temperature (37ºC). Chlorophyll content average was 37.

The appraisal of thermo-adaptability among two calf breeds in the controlled environment was the objective of this study. The first group was Tharparkar and second one was crossbred (Hariana; 25 and 50% and Exotic; 50 and 75%) calves. The investigative period consists of 7 days acclimatization period, and 21 days of thermal exposure at control (25°C), moderate (31°C) and severe (37°C) heat stress (6 hrs. per day).

A study was conducted at Wheat Breeding section, RPCAU, Pusa, Samastipur, Bihar during rabi 2016-17 to evaluate the genotypes of bread wheat (Triticum aestivum L.) for terminal heat tolerance. Observations were recorded on plant height, number of tillers per plant, flag leaf area, days to fifty per cent flowering, canopy temperature, relative water content, spike length, number of grains per spike, spike fertility, chlorophyll content, days to maturity, thousand grain weight, harvest index, yield per plant, thousand grain weight susceptibility index and heat susceptibility index.

Twenty four newly developed maize hybrids along with three commercial checks were evaluated for their yield performance at three locations under heat stress and optimal conditions. Pooled analysis of variance revealed significant differences among hybrids for grain yield. Mean sum of squares due to environments and linear component of environments were significant for all the traits studied.

The present study was conducted to determine genotypic variations for normalized difference vegetation index (NDVI) and canopy temperature (CT) in wheat under terminal heat and combined heat and drought stresses. Forty-four wheat genotypes were evaluated under late sown with irrigation (heat stress) and without irrigation (combined heat and drought stress) in an environment with average temperatures of 28.6°C during the growing season and 30.62°C during the grain filling stage.

Hexaploid wheat (Triticum aestivum) is a globally important crop. Heat, drought and their combination dramatically reduce wheat yield and quality, but the molecular mechanisms underlying wheat tolerance to extreme environments, especially stress combination, are largely unknown.

In bread wheat (Triticum aestivum L. em. Thell.), development of thermal stress tolerant cultivars and realization of potential at yield in hot climate is enshrined goal of our breeding program. By keeping the above fact in view, the present study was conducted in two environments i.e. normal and late sown condition with 10 diverse genotypes, their 45 F1’s and F2’s to magnify the yield level of wheat in high temperature areas by selecting stress tolerant parents and cross combinations.

PsbO is a ubiquitous extrinsic protein of photosystem II required for providing proper environment for water splitting activity of photosystem II. Exposure of wheat to heat stress initially reduces the rate of photosynthesis by disintegrating the photosystem II, primarily by disruption of the oxygen evolving complex (OEC). Here, we identified and cloned putative PsbOgene of 1 kb from wheat cv. HD2329 using de novo assembly. Expression analysis showed higher expression of PsbO transcript in HD2985, as compared to HD2329 during pollination and grain-filling stages.

Chickpea is a cool season pulse and suffers severe yield losses when exposed to higher temperatures during reproductive phase. Stable chickpea production will depend on the release of new cultivars with improved adaptation to drought and high temperature. Twenty five breeding lines of two crosses JG 11 x JG 14 and JAKI 9218 x JG 14 were assessed under timely and late sown situations. High variability was observed for majority of the traits in both the seasons.

Wheat is a major cereal crop of the world and one third of the world's population uses it as a staple food. However, with the changing climatic scenario and prevalence of higher temperatures, heat stress has become a major factor limiting productivity. Hence, the present study was conducted with the objective to develop suitable mitigation strategy to counter the adverse effect of heat stress. The field experiment was conducted during rabi2017-18 and rabi 2018-19 in the Division of Seed Science and Technology, ICAR - Indian Agricultural Research Institute (IARI), New Delhi, India.
