The COz tension is a necessary factor in determining the acidbase equilibrium of the blood. It has been determined for blood both directly, and indirectly through CO2 of the alveolar air. The blood, because of oxidation, reduction, forced breathing, and stasis through constriction of the veins, undergoes variations in the COz tension. Does the cerebrospinal fluid which exists in a more isolated...
The acid-base indicator properties of aqueous and ethanol extracts from calyces of H. sabdariffa (Zobo) and a dye obtained from the ripe fruits of Basella alba (Indian spinach), two local plants, were investigated. A purple coloured dye obtained from the ripe fruits of Basella alba showed a λmax at 580nm, absorptivity of 0.2269 and was found to be photochemically unstable. A deep red coloured d...
The aim of this work was to explore how various surface treatments would change the dispersion component of surface energy and acidbase character of hemp nanofibers, using inverse gas chromatography (IGC), and to investigate the effect of the incorporation of these modified nanofibers into a biopolymer matrix on the properties of their nanocomposites. Bio-nanocomposite materials were prepared f...
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
Longmuir KJ. Interactive computer-assisted instruction in acidbase physiology for mobile computer platforms. Adv Physiol Educ 38: 34–41, 2014; doi:10.1152/advan.00083.2013.—In this project, the traditional lecture hall presentation of acid-base physiology in the first-year medical school curriculum was replaced by interactive, computer-assisted instruction designed primarily for the iPad and ot...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
psychometric properties of automatic thoughts questionnaire and investigation of the relationship between automatic thoughts with cognitive emotion regulation and self regulated learning
When transferred from 865 to 250 m-osmol salinity, the blue crab C. sapidus maintains its blood Na+ and Cl~ concentrations significantly above those in the medium. When branchial carbonic anhydrase is inhibited by acetazolamide, ion regulation fails and the animals do not survive the transfer. An alkalosis occurs in the blood at low salinity, indicated by an increase in HCO3~ and pH at constant...
This study on potentiometric titration of polyprotic acids and bases using a glass electrode is a continuation of our paper (Maslarska V., Tencheva J., Budevsky O., Anal. Bioanal. Chem., 375, 217 (2003)) [1]. The derived earlier theoretical equation was found to fit well the experimental data. A commercial software was applied and main attention was paid to the analytical result rather than to ...
