Rural electrification using renewable energy resources and its environmental impact assessment.

Environ Sci Pollut Res Int 2022 Aug 17. Epub 2022 Aug 17.

Department of Electrical Engineering, Indian Institute of Technology, Roorkee, 247667, Uttarakhand, India.

Integrating a group of generation units and loads into a microgrid improves power supply sustainability, decreases greenhouse gas emissions, and lowers generating costs. However, this integration necessitates the development of an improved energy management system. The microgrid distributes electricity among energy resources to optimize either the generating cost or the quantity of greenhouse gas emissions, or both at the same time. Read More

[Estimation of Agricultural Non-point Source TN and TP Export Coefficients Based on Soil Loss].

Huan Jing Ke Xue 2022 Aug;43(8):4032-4041

State Key Laboratory of Resources and Environmental Information System, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China.

Taking the Yellow River Delta as a typical research area, we constructed a coastal agricultural TN and TP non-point source pollution estimating model by analyzing the relationship between the surface soil pollutant loss risks and the monitored pollutant flux into the sea. On this basis, TN and TP non-point source export coefficients of paddy fields, irrigated land, and dry land were calculated, and the verification showed that the estimated export coefficients were acceptable. In the study area, the TN and TP export coefficients into the sea of arable land were 18. Read More

Albert M Wu

Glycoconj J 2022 Aug 13. Epub 2022 Aug 13.

Glycome Research Laboratory, Institute of Molecular and Cellular Biology, College of Medicine, Chang-Gung University, Tao-yuan, 33302, Taiwan.

Galα1 → and GalNAcα1 → are the two essential key sugars in human blood group AB active glycotopes, in which GalNAcα1 → related sequences are located at both sides of the nonreducing and the reducing ends of human blood group A active O-glycans. It is also found at the nonreducing ends of GlcNAc N-glycans and glycosphingolipid(GSL) of human blood group A active glycotopes (A) and Forssman antigen (F). When monosaccharides and their α, β anomers are involved in basic units to express the complex size of the combining sites of the GalNAcα1 → specific lectins, they can be divided into a cavity site to accommodate the GalNAcα → key sugar and a subsite with a wide and broad range of recognition area to adopt the rest part of sugar sequences or glycotopes.

Towards a North Pacific long-term monitoring program for ocean plastic pollution: A systematic review and recommendations for shorelines.

Environ Pollut 2022 Aug 9:119862. Epub 2022 Aug 9.

Department of Commerce, National Oceanic and Atmospheric Administration, National Marine Fisheries Service, Southeast Fisheries Science Center, Fisheries Statistics Division, Miami, FL, 33149, USA.

Increased organized monitoring is key to improving our understanding of marine debris on shorelines. Shorelines are demonstrated sinks for marine debris but efforts to quantify debris often fail to capture and report core variables and survey design techniques necessary to ensure study repeatability, comparability and to provide meaningful results. Here, we systematically review the available literature regarding marine debris distribution and abundance on shorelines of countries bordering the North Pacific Ocean (NPO), which are demonstrated to have unusually high marine debris abundance and diversity both at the ocean surface and stranded on shorelines.

Enhanced bedside mortality prediction combining point-of-care lactate and the quick Sequential Organ Failure Assessment (qSOFA) score in patients hospitalised with suspected infection in southeast Asia: a cohort study.

Lancet Glob Health 2022 Sep;10(9):e1281-e1288

Mahidol-Oxford Tropical Medicine Research Unit, Faculty of Tropical Medicine, Mahidol University, Bangkok, Thailand; Department of Tropical Hygiene, Faculty of Tropical Medicine, Mahidol University, Bangkok, Thailand.

Background: Simple, bedside prediction of infection-related mortality in low-resource settings is crucial for triage and resource-utilisation decisions.

The Federal State Public Military Educational Institution of Higher Education "The Jhukov Order Saratov Red Banner Institute of National Guard Forces of The Russian Federation", 410023, Saratov, Russia.

The article considers specifics of health-preserving culture of family members of serviceman and parameters of its sociological assessment. It is proved that military personnel consider family as social element of military collective and at the same time as sociocultural subsystem of military unit. The latter determines subordination of sociocultural interests of serviceman family to interests of development of military organization, which manifests itself as a factor complicating development, strengthening contradictions in system of health-preserving culture of this family.
