A Luoi is a mountainous district of Thua Thien Hue province, Vietnam, with rugged terrain, steep slopes, and many valleys. A Luoi district bears many risks of natural disasters such as storms, floods, droughts, and landslides yearly. This study applied the AHP (Analytical Hierarchy Process) model with the GIS tool on the input database of Sentinel-2B Image, DEM, and geographic background data to evaluate the influence of 5 factors: slope, elevation, aspect, land cover, and vegetation to generate a landslide hazard zoning map, scale 1:50,000.

Ebook "Thermophilic carboxydotrophs and their applications in biotechnology" describes the products produced by carboxydotrophic bacteria and their biotechnological applications. Carbon monoxide (CO) is a widespread pollutant and a hazard to man because of its extremely toxic nature. It is a major component of some industrial gas mixtures and may be derived from coal. The carboxydotrophic bacteria obtain energy and carbon from the oxidation of CO. These organisms may be used to produce new metabolites, and the oxidases from them may be used to produce fuel cells and biosensors for CO.

Chitosan is a nitrogen containing polysaccharides that forms a semitransparent horny substance and is a principal constituent of the exoskeleton or outer covering of insects, crustaceans and arachnids. In recent years application of natural antimicrobials instead of conventional ones, due to their hazardous effects on health, has got serious attentions.

Sustainable development is considered as a big concern around the world today. However, the more the economy grows, the more exhausted natural resources become and the more damaged natural environment is. This leads to a spoilt ecological system and hazardous disasters. Besides, economic growth does not go with social equality, morality, culture. It also increases the gap between the rich and the poor or social unrest etc.

Hoa Binh is one of the provinces strongly suffering from natural disasters, especially flash floods. High slope mountainous terrains, reduced vegetation cover and unfavorable weather conditions form favorable conditions for flash floods to occur. This article develops a map of flash flood risk zoning in Hoa Binh using remote sensing and GIS technology.

Land use and land cover (LULC) information is a fundamental component of environmental research related to urban planning, green infrastructure sustainability and natural hazards assessment. In particular, remote sensing technology has demonstrated a powerful capacity for LULC modelling with a corresponding increase in sensor number and type.

Vietnam and Cambodia have same significant strategic benefits in the Mekong Delta. And, the trans-boundary dimension and respective management issues are highline agenda of them. Although, the economic development of each country is different in the boundary region of Mekong Delta, two countries have a same problems as from the natural hazard (including flood, drought, acid sulphate soils, and saltwater intrusion) to the impact of upstream development, a myriad of flood controlling infrastructure, and the implications of climate change.

Photocatalytic degradation of the herbicide quinclorac in water using Mn (III) salen and solar light
Quinclorac (QNC) is a widely used herbicide and is persistent in surface and ground waters. Its residuals and converted products are hazardous to aquatic animals, vegetation, and microbes, and it is therefore important to degrade QNC using an efficient and environmental friendly technology.

The aim of this study was to determine natural radioactive and heavy element concentrations in Mersin drinking water samples before the commissioning of the Akkuyu nuclear power plant and to collect data for possible environmental contaminations in the future. Drinking water samples were taken from the provincial center, districts, and populated villages. The annual effective dose of natural radionuclides and cancer risks were calculated for each person living in the city. Hazard index and cancer risk were calculated, which were caused by heavy elements.

Mammals have wide variations in testicular position, with scrotal testes in some species and ascrotal testes in others. Although cryptorchidism is hazardous to human health, some mammalian taxa are natural cryptorchids. However, the evolution of testicular position and the molecular mechanisms underlying the maintenance of health, including reproductive health, in ascrotal mammals are not clear.

In India, the quantity of “E-Waste” or Electronic Waste has now become a major problem. Electronic wastes (E-Wastes) typically include discarded computer monitors, motherboards, mobile phones and charges, compact discs, headphones, television sets, A.C. and refrigerators. Only 20 percent of global E-Waste is recycled. In India most of the waste electronic items are stored at households as people do not know how to discard them. This ever-increasing waste is very complex in nature and is also a rich source of metals.
