… as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus …
kompressorkyla vs absorptionskyla
… har varit att undersöka potentialen för värmedriven kylproduktion, dvs. absorptionskyla, i Linköpings energisystem. Bakgrunden är att många energibolag söker efter nya avsättningsområden för fjärrvärme pga. det överskott på värme som finns sommartid i energisystem med …
en fältstudie
… period. Since long it is known that potassium has a negative effect on the absorption of magnesium. Due to the fact that potassium fertilisation leads to a higher potassium content in forage, it is of interest to study interactions of potassium on the magnesium balance in dairy …
… impregnation salts effecthow Quartzene® function in terms of moisture absorption and moisture desorption.Quartzene® is a hygroscopic material, which is a material that easily absorbs and exudatesmoisture from the air. Materials with high porosity absorb moisture by adsorption …
Hur absorptionskapacitet och kommunikation påverkar kunskapsöverföringen
Den här uppsatsen ämnar analysera hur absorptionskapacitet och graden av kommunikation påverkar kunskapsöverföringen i ett svenskt multinationellt företag. Genom webbenkäter till företagets totalpopulation (N=540) har data samlats in på individnivå med en svarsfrekvens på 36 …
skillnader i upptag, metabolism och utsöndring mellan gnagare och människa
… body weight.), it is essential to attain a better understanding regarding the absorption, metabolism and secretion of dietary AM. Apart from in vivo studies in rodents, lately some in vivo studies have been performed in humans. 13C NMR och LC/MS are two commonly used techniques …
… plantarum 299v is a probiotic strain proposed to give enhanced iron absorption. An improvement of iron absorption was observed when the strain was added to a phytate rich meal. Trials with longer intervention periods are needed to assess the strain’s impact on iron absorption …
… pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines …

The purpose of this project is to analyze and study the absorption of the substances ivermectin, spinosad and barettin to hydrophobic and hydrophilic surfaces, and to analyze and study if the barnacle larva are effected when they try to settle on the treated surface. Incubation …
… network. Therefore two kinds of heat pumps have been evaluated in the model; absorption heat pumps and compression heat pumps. The main method used for calculations on the heat transfer processes in the storage is the finite difference method. During economic calculations, the …
… is about 20%. Many studies, mainly on dry cows or sheep, have shown that the absorption of magnesium in the rumen is negatively affected by the presence of potassium ions. To compensate the lower uptake, extra magnesium can be supplied when the potassium content in the diet is …
SUMMARYFor thousands of years horses have been at people's side. They have been used for transportation at war, to save time, manpower and money. For practical reason, man has forced the horses into narrow spaces. Stabling includes factors as feeding and bedding. In the boxes …
Definiering och framtagning av nyckeltal
… Resultatet av vår analys visade att anläggningen med kemisk absorption var den med högst tillgänglighet, effektivast ur gasanvändnings- och kostnadssynpunkt men något sämre energieffektivitet än anläggningen med vattenskrubber som var effektivast ur energisynpunkt. Anläggningen …
… fecal losses of Ca and P were greater than previously suggested. A Ca absorption efficiency of 50 % is used for all horses. However, the true absorption efficiency might be as high as 70 % in young horses. P absorption efficiency is assumed to be higher for growing horses …
