The article presents the methods for calculating pressure loss of pneumatic transport system a cotton harvester related to power consumption fan drive. Mathematical models computer calculation are presented. Numerical studies influence pipeline diameter and air mixture composition on drive It was determined that with an increase in from 0.15 m 0.175 change concentration μ = 0.228 ÷ 0.338 serial...

This paper reports a serial dilution microfluidic network composed of microchannels with a high fluidic-resistance ratio for generating linear concentration profiles as well as logarithmic concentration profiles spanning 3 and 6 orders of magnitude. The microfluidic networks were composed of thin fluidic-resistance microchannels with 160 to 730 microm(2) cross-sectional areas and thick diffusio...

Biologic intraindividual variation (CVb) is a major source of inaccuracy in current lipid and lipoprotein measurements. Metaanalysis has been used to estimate the average CVb of serum total cholesterol (TC), high-density lipoprotein cholesterol (HDLC), low-density lipoprotein cholesterol (LDLC), and triglyceride (TG). These CVb values are larger than the National Cholesterol Education Program-a...

The volatile anesthetic isoflurane poses a number of experimental challenges in the laboratory. Due to its rapid evaporation, the open conditions of most in vitro electrophysiological recording systems make the determination of actual isoflurane concentrations a challenge. Since the absolute anesthetic concentration in solution is directly related to efficacy, concentration measurements are imp...

In Rosmarinic Acid (RA) is a phenolic acid which has many biological activities such as antioxidant, anti inflammatory and anti viral effects. In the present study, we have studied the anti Herpes simplex type 1 (HSV-1) effect of methanolic extract of Zataria multiflora which has been standardized on the basis of RA content. Methanolic extract of Zatria multiflora was prepared by maceration met...
