A 21-year-old man presented after being struck by a car and underwent a computed tomography scan of the chest and spine. Three hours later, his clear yellow urine sample was sent to the laboratory. A routine urinalysis with the Roche Urisys® 2400 indicated the specific gravity (SG) as a flag, i.e., an error for SG. A manual repeat of the SG measurement was also not readable by refractometer (no...

Aim—To evaluate the reliability of dipstick measurements of urine specific gravity (U-SG). Methods—Fresh urine specimens were tested for urine pH and osmolality (U-pH, U-Osm) by a pH meter and an osmometer, and for U-SG by three diVerent methods (refractometry, automatic readout of a dipstick (Clinitek-50), and (visual) change of colour of the dipstick). Results—The correlations between the vis...

angelica essential oil (ao), a major pharmacologically active component of angelica sinensis (oliv.) diels, possesses hemogenesis, analgesic activities and sedative effect. the application of ao in pharmaceutical systems had been limited because of its low oxidative stability. the ao-loaded gelatin-chitosan microcapsules with prevention from oxidation were developed and optimized using response...

introduction: water is an essential nutrient for life. it comprises 75% of total body weight in infants,60% in adult males and 50% in adult females. decrease in body water is commonly known as dehydration. acute or chronic dehydration is a common condition in some population groups, especialy the elderly and those who participate in physical activity in warm enviroments. potential consequences ...

The specific gravity (SG) of wood is a measure of the amount of structural material a tree species allocates to support and strength. In recent years, wood specific gravity, traditionally a forester's variable, has become the domain of ecologists exploring the universality of plant functional traits and conservationists estimating global carbon stocks. While these developments have expanded our...

A technique for measuring focal cerebral blood flow (CBF) and brain specific gravity (SG) in gerbils is described; CO2 reactivity and autoregulation were tested. The mean CBF was 29.5 +/- 4.5 ml/100 gm/min and brain SG 1.0500 +/- 0.0004. Unilateral carotid occlusion resulted in a reduction of flow to 12.8 +/- 5.8 ml/100 gm/min in the ipsilateral hemisphere with little change in the contraletera...

This experiment was carried out to evaluate the effect of specific gravity (SG) and particle size (PS) of Chromium-mordanated alfalfa neutral detergent fiber (NDF) markers on estimation of particulate rumen turnover. Thirty-two multiparous, mid lactation Holstein dairy cows (body weight=654±24 kg) were allotted to a completely randomized design experiment with two replications in a 4×4 factoria...

response surface methodology was applied to determine the optimum processing conditions that lead to maximum water loss, weight reduction and minimum solid gain as well as water activity during osmotic dehydration of carrots. temperature (30-50?c), processing time (120-240 min), glucose syrup de=42 (30-50% w/w) and salt (5-15%) concentrations were the factors investigated with respect to water ...

The objective of this study was to compare methods for estimative of body composition of goats based on tritiated water space technique (TOH), specific gravity (SG) of carcass and 9-11 ribs. Ten Toggenburg x Alpine intact male goat kids, from 5.3±0.4 to 25.9±1.3 kg of body weight (BW), were used to estimate body composition by: 1) direct method, 2) TOH method, 3) SG of the carcass and 4) SG of ...
