Calprotectin is a 24 kDa dimer of calcium binding proteins S100A8 and S100A9. [1] The complex accounts for up to 60% of the soluble protein content of the neutrophil cytosol. [2] [3] In vitro studies show that calprotectin has bacteriostatic and fungistatic properties, that arise from its ability to sequester manganese and zinc. [1]
The base of the tree is measured for both height and girth as being the elevation at which the pith of the tree intersects the ground surface beneath, or where the acorn sprouted. [1] [2] On a slope this is considered as halfway between the ground level at the upper and lower sides of the tree. This "breast height" value is a measurement ...
Although the increase in plant size is more or less proportional to plant mass already present, plants do not grow strictly exponentially. [11] In a period of several days, plant growth rate will vary because of diurnal changes in light intensity, and day-to-day differences in the daily light integral. At night, plants will respire and even ...
efficient. Worldwide there are approximately fifty mercury cell chlor-alkali plants in operation [1]. Of those there are eight in the United States (US) [2]. In 2003 the EPA reported in the Federal Register that on average approximately seven tons of mercury were missing from each plant in the year 2000 [3]. These chlor-alkali plants have an
Tree height is the vertical distance between the base of the tree and the highest sprig at the top of the tree. The base of the tree is measured for both height and girth as being the elevation at which the pith of the tree intersects the ground surface beneath, or "where the acorn sprouted."
It is measured as the mean of all annual temperatures, with all temperatures below freezing and above 30 °C adjusted to 0 °C, [4] as most plants are dormant at these temperatures. Holdridge's system uses biotemperature first, rather than the temperate latitude bias of Merriam 's life zones, and does not primarily consider elevation directly.
Crop coefficients are properties of plants used in predicting evapotranspiration (ET). The most basic crop coefficient, K c, is simply the ratio of ET observed for the crop studied over that observed for the well calibrated reference crop under the same conditions.
Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis.It arises once preprocalcitonin is cleaved by endopeptidase. [1]
