Too much exposure in a very hot environment can cause heat stress which leads to the fatal heat stroke. To prevent heat stress related diseases, flexible self adhesive patch for professional heat stress monitoring service has been developed. By using flexible printed circuit board (PCB) and silicone based packaging, high level of robustness and ease of usage has been accomplished. This patch can be repeatedly attached to the chest of the user with comfort. And it can stand the sweat and be washed with water to reuse. For this patch is small in size (9 cm triangle shape) and light in weight (55g), it can be used in the most demanding situation. To analyze the heat stress of user, it records 1 lead electrocardiogram, body temperature, humidity and 2-axis acceleration. It's Bluetoothtrade communication module can connect various terminal device according to the configuration. With the body weight input by user and 3 week work log it can estimate user work load, acclimatization, total amount of work done, wet bulb globe temperature (WBGT) index, which is the screening criteria for heat stress exposure.

With freshwater resources becoming scarce worldwide, mariculture is a promising avenue to sustain aquaculture development, especially by incorporating brackish and saline groundwater (GW) use into fish farming. A 75-day rearing trial was conducted to evaluate fish growth, immune response, overall health, and water quality of Chelon ramada cultured in brackish GW and fed on a basal diet (BD) augmented with rosemary oil (RO) or RO + zymogen forte™ (ZF) as an anti-flatulent. Five treatments were administrated in triplicate: T1: fish-fed BD without additives (control group); T2: fish-fed BD + 0.

Biostimulants are an emerging and innovative class of products that may mitigate the adverse effects of extreme heat, but research on their efficacy in fruit crops is limited. This study addressed this knowledge gap by evaluating the performance of three biostimulants, FRUIT ARMOR™, Optysil®, and KelpXpress™ [active ingredients glycine betaine, silicon, and kelp (Ascophyllum nodosum) extract, respectively] applied to three raspberry genotypes exposed to high temperatures (T ≥ 35 °C/day) inside a glasshouse. 'Meeker' consistently maintained high chlorophyll fluorescence (F/F) and photosynthesis under control and biostimulant treatments.

RP-HPLC technique was developed and optimized for simultaneous identification and estimation of nirmatrelvir (NIR) and ritonavir (RIT) in their new copackaged tablet. Stability of nirmatrelvir (NIR) was studied after exposure to different five stress conditions; alkali, acid, heat, photo and oxidation degradation. The chromatographic separation was achieved using VDSpher PUR 100 ODS (4.

Climate change-induced rise in sea surface temperatures has led to an increase in the frequency and severity of coral bleaching events, ultimately leading to the deterioration of coral reefs, globally. However, the reef-building corals have an inherent capacity to acclimatize to thermal stress on pre-exposure to high temperatures by altering their endosymbiotic Symbiodiniaceae community composition towards a thermal tolerant composition. This reorganisation may become an important tool in coral's resilience to rapid environmental change.
