Volume adjusting

The slide is located in the compressor casting below the rotors, allowing internal gas recirculation without compression. Slide valve is operated by a piston located in a hydraulic cylinder and actuated by high-pressure oil from both sides. When the compressor is started, the slide valve is fuUy open and the compressor is unloaded. To increase capacity, a solenoid valve on the hydraulic hne opens, moving the piston in the direction of increasing capacity. In order to increase partload efficiency, the slide valve is designed to consist of two parts, one traditional shde valve for capacity regulation and other for built-in volume adjustment. 

The mixture of broth and mycelium thus formed was then transferred under aseptic conditions to a 3-iiter fermentor containing 2 00 ml of a sterile fermentation medium having the following composition 60 g Cerelose (dextrose hydrate), 18 g soybean meal, 5 g distillers solubles, 12 g cornmeal and tap water in a sufficient amount for a 1,000-ml total volume, adjusted to pH 7.0 to 7.2 with potassium hydroxide. 

Alveolar ventilation. Alveolar ventilation is less than the total ventilation because the last portion of each tidal volume remains in the conducting airways therefore, that air does not participate in gas exchange. As mentioned at the beginning of the chapter, the volume of the conducting airways is referred to as anatomical dead space. The calculation of alveolar ventilation includes the tidal volume adjusted for anatomical dead space and includes only air that actually reaches the respiratory zone ...

To characterize the relative gas-chromatographic retentions of condensed aromatics and heteroaromatics, inclu g thienothiophenes, benzo[b]thiophene, dibenzothiophene, naphthobenzothiophenes, and anthrabenzothiophenes, a system of indices. In, was proposed, In this system a series of similar linearly condensed hydrocarbons (such as benzene, naphthalene, anthracene, tetracene, pentacene,...) was used as a reference scale. The logarithm of the corrected retention volume (adjusted to 0°), log Ft, depends linearly upon the number of condensed benzene rings (z) in the molecule, both in the polar and nonpolar phases. In is expressed by Eq. (58) ... 

Sastry and Aruna described the use of 3-methyl-2-benzothiazolinone hydrazone hydrochloride as a new technique for the spectrophotometric determination of diloxanide furoate and other anthelmentic and antiamoebic agents [29]. Aliquots of sample solutions containing 10-100 pg of drug substance were transferred into a series of 10 mL graduated test tubes, and the volume adjusted to 3 mL with the respective solvent blank. 3-Methyl-2-benzothiazolinone hydrazone hydrochloride and 1 mL of Cr(VI) were added, and the mixture diluted with methanol. The absorbance at 500 nm was measured against a reagent blank. 

Friedman, Dasari, and colleagues conducted more recent structural MRI studies of children and adolescents 10 to 18 years of age, including 20 with schizophrenia, 15 with BD, and 16 healthy controls. Decreased thalamic volume (adjusted for total brain volume), decreased intracranial volume, and increased frontal and temporal sulcal size were found in the combined patient group compared to measurements in the healthy control group. However, differences were not detected between the two diagnostic groups (Dasari et ah, 1999 Friedman et ah, 1999). 

Dilution. It is important to be aware that the dilution process utilized by the automated workstation may differ from a manual process. Adjustments in dilution factors may be required and considerations of the density value of the diluting solvent and sample filtrate are valuable. In some cases the dilution step can be avoided when designing the automated sample preparation through initial volume adjustment whenever possible and/or through changes in the injection loop size to achieve proper column loading. 

Phosphoenolpyruvic acid monopotassium salt (KPEP) [4265-07-0] M 206.1. It is purified via the monocyclohexylamine salt (see next entry). The salt (534mg) in H2O (10ml) is added to Dowex 50 H form (x 4 2 X)-400 mesh, 2ml, H2O washed) and stirred gently for 30min and filtered. The resin is washed with H2O (6ml) and the combined solns are adjusted to pH 7.4 with 3N KOH ( 1.4ml) and the volume adjusted to 18.4ml with H2O to give a soln of O.IM KPEP which can be lyophilised to a pure powder and is very good for enzyme work. It has been recrystd from MeOH-Et2O. It has pKa values of 3.4 and 6.35 in H2O.

A 9] The thin-film three-electrode cell possesses a cell volume adjustable from 0.75 to 2.5 pi. The fluid dynamic design of the cell should prevent turbulence. The reference electrode, an Ag/AgCl cell element, can be filled manually with KC1. A transparent housing permits optical control of the liquid level. The operational pressure is limited to 5 bar. The supplier recommends this robust device for routine measurements when high selectivity is desired.

The sulfite extract of the pecan nut pith was obtained by extracting the finely ground red powder (509 gm) with sodium sulfite (20.4 gm) and sodium carbonate (2.0 gm) in 2549 mL of water. Approximately 1 hr was required to reach reflux temperature, and the suspension was heated at reflux for 2 hr. The suspension was cooled, the volume adjusted to a constant by addition of water, and it was filtered twice through glass wool. Aliquots (100 mL) of the recovered liquor were freeze-dried to determine the extract yield. The remainder was also freeze-dried to recover a dark brown solid.
