β-Cyclodextrin exists as a white (colorless) powder or crystals. The density of its saturated hydrate crystal (βCD·12H 2 O) is 1.46 g/cm 3 . β-Cyclodextrin is moderately soluble in water and glycerin ; well soluble in dimethyl sulfoxide , dimethylformamide , pyridine , HFIP , and ethylene glycol ; and insoluble in ethanol and acetone .
Prior to the 1970s, Bangladesh had one of the highest infant mortality rates in the world. Ineffective water purification and sewage systems as well as periodic monsoons and flooding exacerbated these problems. As a solution, UNICEF and the World Bank advocated the use of wells to tap into deeper groundwater. During the 1970s, UNICEF worked ...
Tubewells serve as the main source of drinking water in rural Bangladesh, with access to water for rural populations increasing from 65% in 1990 to 97% in 2015.

Hard water can cause scale buildup in pipes, valves, and filters, reducing performance and adding to system maintenance costs. These effects can be seen in aquariums, spas, swimming pools, and reverse osmosis water treatment systems. Typically, total dissolved solids are tested frequently in these applications, and filtration membranes are ...
