Apparent electrostatic persistence lengths (i.e., those found by substituting the perturbed for the unperturbed mean-square gyration radius in the wormlike chain theory) obtained from static light scattering for variably ionized acrylamideJsodium acrylate copolymers varied approximately as the inverse square root of the ionic strength, C,, and linearly with fractional ionization. While this doe...

The abundance of bacteria in liquid culture is commonly inferred by measuring optical density at 600 nm. Red fluorescent proteins (RFPs) can strongly absorb light at 600 nm. Increasing RFP expression can falsely inflate apparent cell density and lead to underestimations of mean per-cell fluorescence by up to 10%. Measuring optical density at 700 nm would allow estimation of cell abundance unaff...

Healthy bones adapt to mechanical stimulus in a process known as bone remodeling. More specifically, the apparent density of bone tissue is directly related to the load it bears over time. For example, after long periods in a microgravity environment astronauts experience a loss of bone density because of skeletal unloading, while most professional tennis players experience a gain of bone densi...

flow characteristics and rheological parameters of “malas yazdi” pomegranate (punica granatum l.) juice were investigated using rotational viscometer at different temperatures (10, 20, 30, 40, 50, 60 and 70ºc) and concentrations (12, 22, 32, 42 and 52º brix). the experimental data had the best fitness with herschel-bulkley model and the values of flow behavior index (n) varied between 0.97 and ...

and Computed Tomography Density in Acute Ischemic Stroke To the Editor: We read with interest the recent article by Kucinski et al.1 The authors observed a decrease in the apparent diffusion coefficient (ADC) in diffusion-weighted MR imaging and a corresponding decrease in CT density in patients suffering from acute ischemic stroke of the anterior cerebral circulation. CT measurements showed a ...

Monolithic aerogels of high molecular weight polyethylene (Mw= 3x106- 6x106 g/mol) have been prepared by solvent extraction with supercritical carbon dioxide from thermoreversible gels prepared in decalin. These low density and highly porous aerogels present an apparent porosity up to 90%. The aerogel morphology observed by scanning electron microscopy (SEM) is characterized by spherulitic stru...

In [1,2] the observed decrease in spectral peak energies of IMFs emitted from hot nuclei was interpreted in terms of a breakup density that decreased with increasing excitation energy. Subsequently, Raduta et al. [3] performed MMM simulations that showed decreasing spectral peaks could be obtained at constant density. In this letter we examine this apparent inconsistency.

11beta-Hydroxysteroid dehydrogenase type 2 (11betaHSD2) is a short-chain dehydrogenase/reductase (SDR) responsible for inactivating cortisol and preventing its binding to the mineralocorticoid receptor (MR). Nonfunctional mutations in HSD11B2, the gene encoding 11betaHSD2, cause the hypertensive syndrome of apparent mineralocorticoid excess (AME). Like other such Mendelian disorders, AME is rar...

Apparent mineralocorticoid excess (AME) syndrome is a rare autosomal recessive disorder due to the deficiency of 11b hydroxysteroid dehydrogenase type 2 enzyme (11beta-HSD2). Mutations in this gene affect the enzymatic activity resulting to an excess of cortisol, which causes its inappropriate access to mineralocorticoid receptor leading to inherited hypertension.This is a potentially fatal but...

Brick is a building material that often used for residential walls. The bricks in this study were with the addition of palm frond charcoal manufacturing process. aims (1) to determine effect adding stem on manufacture red terms compressive strength, water absorption (Suction rate) and apparent density (apparent density). (2) Comparing test results SNI 15-2094-2000 standard. experimental begins ...
