However if there is no other alternative source the maximum level is permissible up to 600mg/l.Hence level below 300 mg/l is good. This only represents hardness. The more hard the water is, the more sediments are formed in cooking vessels using this hard water, and water may taste ...
You just need to make sure the fish have the same water preferences as your discus fish. The ideal pH range for this cichlid species is between 6 and 7 with a hardness of approximately 2 dKH. Discus require a warmer water temperature than the majority of other tropical fish species – be...
For comparison, Fig.1provides an overview of the ionic conductivities (low to high conductivity range in (b)) and the activation energy of key ionic conductors along with their structures. The chronological order of their discovery is also displayed in Fig.1a. Notably, Yttria (Y2O3) stabilized ...
With a tough, scratch resistant coating, and the ability to survive point pressures of up to 100 kg, Prior Scientific’s HT series of stages are the ideal systems for use in hardness testing applications. The stage can be used with an extensive range of sample holders supplied by Prior Scie...

IMHO when designing a telescope numerous factors need to be taken into account, the highest Abbe number alone for the central element is not the only desirable characteristic. Things like thermal conductivity, expansion coefficients, abrasion, hardness, acid and water resistance...are all important ...

Water-soluble coolant ○○ Oil-based coolant ×○* Coolant filtration accuracy 40 μm 20 μm * Oil-based coolant may not be filtered appropriately depending on its viscosity. In such cases it is advisable to select the high-pressure coolant unit (special option), which uses a ceramic backw...
Dry soluble substances are mostly represented by sugars (fructose, glucose, and sucrose), organic acids (whose total is determined as a titratable acid), water-soluble vitamins (ascorbic acid and vitamin P-active catechins and leuco-anthocyanins), tannins and dyes, pectins, and mineral salts [...
