The microdynamic mechanism of the phenomenon, which the static permittivity of sodium chloride aqueous solution with concentration of 2.8 mol/L holds constant with the change of temperature, is clarified. The equilibrium compensation between the decrement of the permittivity part due to the water molecular polarization and the increase of that originated from the ionic polarization as increasing temperature is responsible for this phenomenon. The dipole moment reduction of water molecules as rising temperature is also confirmed by the model.

Ebook "Viruses in foods (Food microbiology and food safety series)" is the first book that comprehensively discusses the role of viruses in foodborne disease outbreaks, along with strategies for the prevention and control of viral contamination of food. Cases of viral foodborne outbreaks are on the rise in part due to the increases in population, scarcity of clean water, and changes in eating habits.

From ancient times, water has always been considered an important resource that played crucial roles in the rise and fall of human civilizations. For its essential and irreplaceable parts on the health, dignity, and prosperity of people, the access to water has been recognized by the United Nations as an important human right, and could significantly affect the realization of other fundamental human rights.

The impact of climate change on sea level has attracted much attention from scientists worldwide. The analysis of sea-level change at global and regional scales is based on altimetry and/or tide gauge data. The main objective’s study relied on statistical tests to highlight the significant long-term changes in sea level in Ha Long coastal area through the 47 years (1974–2020) historical tide gauge record of the Bai Chay station.

Flood is a natural disaster that can cause loss of life and damage to property. The objective of this study is to create a flood map of Yen Bai city, where flood occurs regularly during heavy rain and Thao River's water level rises. The study used Mike Flood model based on the connection of 1D and 2D hydrodynamic models.

The rapid global population growth leads to considerable rising consumption of natural resources such as air, water, and land. The demand for land has increased in the last two decades, both inland and seaside. Land reclamation along with the coastline has been preferred as a solution for modern urban development, such as three land reclamation projects in Rach-Gia Bay, the Vietnamese Mekong Delta.

Analysis of ca. 1400 km of multichannel seismic data indicate that the distal part of the Sakarya Canyon within the continental rise is an unstable region with sediment erosion. Fourteen buried debris flows (DB1–DB14), in the stacked form within Plio–Quaternary sediments between 1400 and 1950 m water depth, were observed in the surveyed area. Their run-out distances range from 3.8 to 24.4 km. The largest debris flow DB10 affects ca. 225 km2 surficial area transporting ca. 15 km3 of sediment in S to N direction.

Before this earthquake, water resources were monitored in the areas of Bayraklı, Gülbahçe, and Seferihisar. For this purpose, 10 groundwater monitoring wells were drilled in the Bayraklı area, where groundwater level, temperature, and electrical conductivity changes were monitored at 1-h intervals in 5 wells. Besides physical parameters such as groundwater levels, temperatures and electrical conductivities, hydrogeochemical cations, and anions measured in the study area. Change in the groundwater levels was observed before, during, and after the Samos earthquake.

The impact of rising levels of various heavy metals in the environment from multiple industrial, agriculture, domestic, and technological activities is of great concerns, as heavy metals cause serious health effects for both humans and wildlife. An effective and green chemistry procedure was used for simultaneous extraction of ultra-trace copper and nickel ions in natural waters (e.g. river and well waters) by air assisted liquid-liquid microextraction combined with solidified floating organic drop microextraction (AALLMESFOD).

A deep understanding of current and projected flood risk is need for effective flood risk management and better adaptation planning under climate change. This research aims to investigate the direct impacts of climate change on flood damage to rice under changes in water depth and flood extent induced by rainfall increase and sea-level rise.

Aedes aegypti mosquito, the principal global vector of arboviral diseases, lays eggs and undergoes larval and pupal development to become adult mosquitoes in fresh water (FW). It has recently been observed to develop in coastal brackish water (BW) habitats of up to 50% sea water, and such salinity tolerance shown to be an inheritable trait.

Typhoon surge is the phenomenon of seawater level rises higher than the normal levels (tidal water level) under the combined effect of many factors during typhoons. Along the Vietnam coast, this phenomenon occurred quite often and very dangerous, especially when occurring at the same time with high tide. There are manyresearch projects and publications relative to this problem, such as National projects. This phenomenon caused by strong wind and air pressure depression during typhoon acting therefore often happened before or just during the typhoon landfall.

Drought is the major abiotic stress that results in severe loss of yield to crops. It is estimated that there will be a steep rise in global water consumption in the coming years. On the other hand, it is also estimated that the sources of water will deplete due to rise in temperature and climate change. It is, therefore, critical to find out such genotypes of crops that have the ability to tolerate drought without much loss of yield.

Among the crop residues used for preparation of compost, wheat straw (WS) + urea (1.5 - 4.5 per cent) + rock phosphate (RP) (6 - 12 per cent) + Sulphur (S) (1 to 3% through gypsum) and shredded cotton stalk (SCS) + urea (1.5 - 4.5%) + RP (6 – 12%) + S (1 to 3% through gypsum) were found equally beneficial in improving the quality of compost. The pH of compost rises initially and further drop at the maturity of compost.

A wheat growth model that includes the direct responses of canopy photosynthesis and transpiration to elevated CO2, and the response of crop growth to water stress has been developed and tested. Sensitivity analyses show that different cultivars have quite different responses to changes in ambient air temperature, ambient CO2 concentration and rainfall. Because crops reach maturity earlier under higher temperature, an increase of 3 oC may not impose further water stress to growth of a wheat crop.
