Application of effective remedies of fight against salt sedimentation gives the chance of creation of the reverse, closed and drainless systems conforming to requirements of modern production and ecology. Salt sedimentation inhibitors at an additive to water from 2,0 to 10 g/m3 for 90% and more prevent scaling on a surface of heatexchange devices, boilers, pipelines, etc. For the purpose of dev...

Received Sep 2, 2016 Revised Aug 2, 2017 Accepted Aug 30, 2017 For decades, petroleum-based mineral oils are the insulating media conventionally used in the industry, particularly for high voltage (HV) applications. However, due to the disadvantages of mineral oils, there is growing interest in replacing these oils with environmentally friendly alternatives in order to fulfill the demanding req...

Requirements Engineering (RE) is getting more attention as it has been recognized as a crucial phase in the development of the software system life cycle. Recent works have made a distinction between early-phase RE and later-phase RE. Early-phases RE activities are typically informal and addresses non-functional requirements. The later-phase RE usually focuses on completeness, consistency, and ...

PURPOSE This study was performed to evaluate the dietary nutrient intake status and hair mineral content of Korean young children. METHODS Fifty-five children who visited Seoul National University Bundang Hospital were divided into three groups by age: infants, toddlers, and preschoolers. The 24-hour recall method was used to collect the food intake data of the subjects. Hair mineral analysis...

The objective of this work was to evaluate the effects of potassium (K) fertilization on vegetative growth, fruit production and leaf mineral content of olive tree (Olea europeae L.) under rainfed condition. Different fertilizer, techniques and rates of application were applied in 2003 on Chemlali olive. The potassium fertilizer used was potassium nitrate. The foliar fertilizer rates were 50 an...

Five camels and 5 cows were fed with a similar basal diet for six months. They received oral trace element supplementation for 3 months (day 22-112). The supplementation included zinc, copper, selenium, manganese, iodine and cobalt, and corresponded to twice the daily requirement generally recommended for cows. Plasma selenium concentration was significantly lower in the camels (20 ± 2 ng/ml) a...

Alizarin red S (ARS) staining has been used for decades to evaluate calcium-rich deposits by cells in culture. It is particularly versatile in that the dye can be extracted from the stained monolayer and assayed. This study describes a sensitive method for the recovery and semiquantification of ARS in a stained monolayer by acetic acid extraction and neutralization with ammonium hydroxide follo...

Copper is a unique mineral, When it is added to pig diets at a high level (much higher than the nutritional requirement), copper stimulates growth and feed efficiency much like antibiotics do. This effect is particularly evident with young pigs. Table 1 shows results of UK studies over a 1 &year period in which high copper diets were fed to weanling pigs (from 17 to 40 lb). Copper increased gro...

The changes of magnesium utilization during pregnancy in rat and the influence of hydrocortisone acetate on it was studied. In the late days of gestation the Mg balance and magnesium content of bone increased significantly. This may be due to a greater requirement at this stage and to bone acting as a store for this cation. Hydrocortisone acetate at a dose of 4 mg/100 g body weight/day decrease...

Marine hydrothermal microorganisms respond rapidly to changes in the concentrations and availability of metals within their environment. Hyperthermophilic archaea appear to possess novel mechanisms for metal detoxification, dissimilatory metal reduction and metal assimilation that may be absent in their mesophilic and bacterial counterparts. For example, tungsten was found in high concentration...
