«density measurement specific gravity»
۴۲۰ نتیجهA reagent strip for measuring the specific gravity of urine.
A solid-phase reagent for determination of urinary specific gravity (relative density) is described. This reagent strip, similar to others in the "N-Multistix" series (Ames), contains a polyacid whose acidity is sensitive to the ionic concentration in the urine in which it is imm
Enhancement of mammographic density measures in breast cancer risk prediction.
BACKGROUND Mammographic density is a strong risk factor for breast cancer. METHODS We present a novel approach to enhance area density measures that takes advantage of the relative density of the pectoral muscle that appears in lateral mammographic views. We hypothesized that the
The Application of the Falling-drop Method for Specific Gravity Measurement to the Determination of Serum Albumin *
Weech and collaborators10 confirmed the formula in 1933. In 1934 Nugent5 demonstrated that the partial specific gravities of albumin and globulin are practically identical. Weech and collaborators' in 1936 worked out formulae by means of which the protein content of plasma, serum
Application of the Algebraic Difference Approach for Developing Self-Referencing Specific Gravity and Biomass Equations
Biomass estimation is critical for looking at ecosystem processes and as a measure of stand yield. The density-integral approach allows for coincident estimation of stem profile and biomass. The algebraic difference approach (ADA) permits the derivation of dynamic or nonstatic fu
Fractional sodium excretion, urinary osmolality and specific gravity in preterm infants fed with fortified donor human milk.
OBJECTIVE This research was performed with the objective of investigating the renal effects on premature newborn infants of fortifying banked donor human milk. METHODS Clinical intervention trial, of the before-and-after type, involving 28 premature newborn infants split into two
Wood Specific Gravity Variations and Biomass of Central African Tree Species: The Simple Choice of the Outer Wood
CONTEXT Wood specific gravity is a key element in tropical forest ecology. It integrates many aspects of tree mechanical properties and functioning and is an important predictor of tree biomass. Wood specific gravity varies widely among and within species and also within individu
Replacing creatinine measurements with specific gravity values to adjust urine cotinine concentrations.
Creatinine and specific gravity (relative density) measurements both allow differences in urine concentration to be taken into account in determining urine cotinine concentrations. In this study we demonstrate that the variance of urine cotinine measurements is reduced comparably
Properties of Medium-Density Fiberboard Related to Hardwood Specific Gravity
Boards of acceptable quality were made from barky material, pressure-refined from 14 species of southern hardwoods. Static bending and tensile properties (parallel to surface) of specimens were negatively correlated to stem specific gravity (wood plus bark), chip bulk density, an
Measuring wood specific gravity...Correctly.
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 pla
Sensing the strike of a predator fish depends on the specific gravity of a prey fish.
The ability of a predator fish to capture a prey fish depends on the hydrodynamics of the prey and its behavioral response to the predator's strike. Despite the importance of this predator-prey interaction to the ecology and evolution of a diversity of fish, it is unclear what fa
