Hydrodynamic conditions are important factors for planktonic algae growth, through introducing two parameters which express the optimal velocity and the velocity range for planktonic algae growth, a new velocity factor was put forward for the formula of growth rate. Therefore, the two-dimensional unsteady ecological dynamicmodel for algae growthwas established to analyze the effects of hydrodyn...

T his article describes an important improvement in the calculation of the Consumer Price Index (CPI). The Bureau of Labor Statistics plans to use a new geometric mean formula for calculating most of the basic components of the Consumer Price Index for all Urban Consumers (CPI-U) and the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). This change will become effective ...

BACKGROUND Portal hypertension is a major risk factor for hepatic failure or bleeding in patients who have undergone hepatectomy, but it cannot be measured indirectly. We attempted to evaluate the intraoperative ultrasonography parameters that correlate with portal pressure (PP) in patients undergoing hepatectomy. METHODS We examined 30 patients in whom PP was directly measured during surgery...

We evaluate the thermodynamic critical angular velocity Ωc(T ) for creation of a vortex of lowest quantized angular momentum in a strictly two-dimensional Bose gas at temperature T , using a mean-field two-fluid model for the condensate and the thermal cloud. Our results show that (i) a Thomas-Fermi description of the condensate badly fails in predicting the particle density profiles and the en...

the aim of this study was to assess the effect of external focus of attention instruction during walking training on old women’s gait kinematic parameters including stride length, velocity, variability of velocity, cadence and double support percent. for this purpose, 16 old women (mean age 69.8+4 years) were selected and randomly assigned to experimental and control groups (each group 8 subjec...

Within wall turbulence, there is a sublayer where the mean wall-normal flux of streamwise momentum constant and related to logarithmic profile velocity. This relation, i.e., law wall, has been used estimate stress at surface. However, exhibits large temporal fluctuations. To relate them theoretically those velocity same position from we consider an orthogonal decomposition fluctuations on plane...

OBJECTIVE To compare weight (per kg)- vs body surface area (BSA, per m(2) )-based growth hormone (GH) dosing formats in children and to derive a useful conversion formula between the two formats. PATIENTS AND DESIGN Growth hormone doses (>33,000) from 1874 children were obtained from the national Australian database (OZGROW) and used to derive conversion formulae and to confirm the accuracy o...
