Resistive particle counting has been developed for the accurate sizing and counting of mitochondria in solution. The normal detection limit with a 30 micro aperture is 0.48 micro diameter, or 0.056 micro(3) particle volume The mean volume of rat liver mitochondria was 0.42 micro(3) or 0.93 micro in diameter. The average value for numbers of particles per milligram of mitochondrial protein was 4...
The droplet size distribution in the column is usually represented as the average volume to surface area, known as the Sauter mean drop diameter. It is a key variable in the extraction column design. A study of the drop size distribution and Sauter-mean drop diameter for a liquid-liquid extraction column has been presented for a range of operating conditions and three different liquid-liquid sy...
BACKGROUND The ways in which cells set the size of intracellular structures is an important but largely unsolved problem [1]. Early embryonic divisions pose special problems in this regard. Many checkpoints common in somatic cells are missing from these divisions, which are characterized by rapid reductions in cell size and short cell cycles [2]. Embryonic cells must therefore possess simple an...
In a panmictic population of constant size N, random pairs individuals will have most recent shared ancestor who lived slightly more than 0.5 log2N generations previously, on average. The probability that pair share at least one ago, or recently, is about 50%. Those individuals, if they do an from generation, would be cousins degree (0.5 log2N) - 1. Shared ancestry progressively earlier increas...
