The comment by Latasa (2014) highlights an important point for the compilation and analysis of data on phytoplankton growth and microzooplankton grazing rates by the dilution technique—the desirability of reporting and utilizing all data. This is a useful and refreshing perspective given statements made elsewhere that dilution results with insignificant regression slopes (i.e., nonsignificant g...

Wastewaters are commonly discharged into the seas and oceans through multiport diffusers. Accurate prediction of complex interactions diffusers with receiving water bodies is significant for optimal design outfall systems has yet to be fully illuminated. In current study, mixing dilution characteristics multiple inclined dense jets studied using a three-dimensional numerical simulation. The Lau...

Selenomonas ruminantium HD4 and Bacteroides ruminicola B(1)4 were grown in continuous culture with glucose as the energy source, and heat production was measured continuously with a microcalorimeter. Because the bacteria were grown under steady-state conditions, it was possible to calculate complete energy balances for substrate utilization and product formation (cells, fermentation acids, and ...

A biofouling simulation system consisting of a flow cell and a recirculation tank was used. The fluid circulates at a flow rate of 350 L· h⁻¹ in a semicircular flow cell with hydraulic diameter of 18.3 mm, corresponding to an average velocity of 0.275 m· s⁻¹. Using computational fluid dynamics for flow simulation, an average wall shear stress of 0.4 Pa was predicted. The validity of the numeric...

Dissolved HL has been used as an indicator for measuring cardiac output by the techniques of constant-rate injection and sudden, single injection indicator dilution. Because of its low solubility, H2 is eliminated essentially quantitatively in the lungs and recirculates negligibly. The constant-rate injection technique involves the gas chromatographic measurement of pulmonary (or systemic) arte...

To determine that susceptibility of AMPLICOR Chlamydia trachomatis PCR to inhibitory factors possibly present in cervical specimens, we obtained cervical specimens from 200 gynecology patients attending our outpatient clinic. The prevalence of C. trachomatis infection was 4.1%, as determined by cell culture. All AMPLICOR specimens were tested in one procedure as described by the manufacturer, a...

The aims of this study were to investigate improvements to the pig preimplantation embryo culture system using in vitro produced embryos. For experiment 1, the optimum time to change the medium from NCSU23 containing 0.6 mM glucose, 0.2 mM pyruvate, 5.7 mM lactate and nonessential amino acids to NCSU23 containing 5.6 mM glucose and both essential and nonessential amino acids was examined. There...

mRNA steady-state levels and activities of enzymes of intermediary carbon metabolism (hexokinase, phosphoglucoisomerase, phosphofructokinase, glucose-6-phosphate dehydrogenase, phosphoglucomutase) and glucose-regulated enzymes (pyruvate decarboxylase, pyruvate dehydrogenase, invertase, alcohol dehydrogenase) were determined in glucose-limited continuous cultures of an industrial strain of Sacch...
