Colostrum samples from 88 Jersey cows were analyzed for concentrations of IgG, IgM, IgA, total solids, specific gravity, and N fractions. Colostrum (50 ml) was sampled from each cow as soon as possible after parturition, and specific gravity was determined immediately using a hydrometer. Samples then were frozen prior to analysis of Ig, fat, and N fractions. Mean concentrations of IgG, IgM, and...

The specific gravity of spores of Pasteuria penetrans collected from Meloidogyne arenaria was found to be around 1.28. Increasing the sucrose concentration used for the extraction of Pratylenchus scribneri from a specific gravity of 1.14 to 1.26 led to the recovery of higher numbers of specimens filled with spores of Pasteuria sp. (P </= 0.05). The numbers of spore-filled specimens of Hoplolaim...

In 1930 Moore and Van Slyke (1) reviewed the various physical measurements, refractometric and others, that might serve as measures of the protein concentration of plasma, and concluded that specific gravity was the most reliable if application was required to pathological as well as normal plasmas. For plasma of nephritic patients they found that the relation between protein concentration and ...

1. The specific gravity and zinc concentration of plasma obtained during fasting were measured in preand post-menopausal women. A number of the latter had been taking 20-40 pg of mestranol daily for at least 1 year. 2. A highly significant correlation was found between plasma zinc concentration and plasma specific gravity in the oophorectomized women who were not receiving oestrogens. 3. The me...

BACKGROUND The usage of urine protein/creatinine ratio to estimate daily urine protein excretion is prevalent, but relatively little attention has been paid to the influence of urine concentration and its impact on test accuracy. We took advantage of 24-hour urine collection to examine both urine protein/creatinine ratio (UPCR) and daily urine protein excretion, with the latter as the reference...

In this paper we derive the equations for the continuous ideal magnetohydrodynamic (MHD) spectrum of twodimensional coronal loops, including gravity and expansion, in general curvilinear coordinates. The equations clearly show the coupling between Alfvén and slow magnetosonic continuum waves when both pressure and geodesic curvature of the magnetic field lines are present. Gravity always gives ...

The formation and fate of sulfide in a force main and a downstream-located gravity sewer were investigated in an extensive field study. Sulfide formation in the force main was significant. However, during 14 minutes of transport in the gravity sewer, the sulfide concentration decreased 30%, on average. An application of a conceptual sewer process model for simulating the formation and fate of s...

Electrochemical deposition (ECD) in thin cells with different orientations relative to gravity leads to complex stable and unstable physicochemical hydrodynamic flows. Here we study the impact of gravity on these flows through a theoretical macroscopic 3D model and its numerical simulation. The model describes the diffusive, migratory, and convective motion of ions in a fluid subject to an elec...
