WaterML 2.0 is an open standard [2] of the OGC. Version 2.0 marks a harmonisation with different formats from various organisations and countries, including the Australian Water Data Transfer Format, WaterML 1.0 from the United States, [3] XHydro from Germany, and with existing OGC formats. WaterML 2.0 was adopted as an official standard by the ...
Cell bank. A cell bank is a facility that stores cells of specific genome for the purpose of future use in a product or medicinal needs, but can also describe the entity of stored cells itself. Cell banks often contain expansive amounts of base cell material that can be utilized for various projects. Cell banks can be used to generate detailed ...
A tabular data card proposed for Babbage's Analytical Engine showing a key–value pair, in this instance a number and its base-ten logarithm. A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table.
Total dissolved solids ( TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular ( colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.
Each cell needs around 1 cm 3 of air per minute at a 10 mA discharge rate. These cells are commonly used in hearing aids. A sealing tab keeps air out of the cell in storage; a few weeks after breaking the seal the electrolyte will dry out and the battery becomes unusable, regardless of use. Nominal voltage on discharge is 1.2 V.
For a confined aquifer or aquitard, storativity is the vertically integrated specific storage value. Specific storage is the volume of water released from one unit volume of the aquifer under one unit decline in head. This is related to both the compressibility of the aquifer and the compressibility of the water itself.
A solid oxide electrolyzer cell ( SOEC) is a solid oxide fuel cell that runs in regenerative mode to achieve the electrolysis of water (and/or carbon dioxide) [ 1] by using a solid oxide, or ceramic, electrolyte to produce hydrogen gas [ 2] (and/or carbon monoxide) and oxygen. The production of pure hydrogen is compelling because it is a clean ...
According to nutrition expert Kimberly Snyder, water-dense spinach is one of the most nutrient-packed vegetables, with high levels of vitamins A, C, and K as well as iron and magnesium. Snyder and ...
