Effect of mechanical agitation on hybridoma cell growth
(Kluwer Academic Publishers; Springer Science+Business Media, 1988-09)
Hybridoma cells (S3H5/γ2bA2) were grown in spinner flasks at different agitation speeds. It was found that cells in stationary and decline phases of growth were sensitive to shear force caused by agitation but cells in ...
The thermodynamic properties of [beta]-UO3 and [gamma]-UO3
(Elsevier, 1988-02-18)
Heat capacities of carefully characterized samples of [beta]-UO3 and [gamma]-UO3, have been measured from 5 to 350 K using an adiabatic calorimeter, and from 350 to 700 K by enthalpy increment drop calorimetry. Values for ...
Differential uptake and metabolism of free and esterified cholesterol from high-density lipoproteins in the ovary
(Elsevier, 1988-04-15)
Rat luteal cells utilize high-density lipoproteins (HDL) as a source of cholesterol for steroid synthesis. Both the free and esterified cholesterol of HDL are utilized by these cells. In this report, we have examined the ...
Thioalkylation of Meldrum 's Acid: Protected alkylidene derivatives of isopropylidene malonate
(WILEY-VCH Verlag GmbH, 1988-12-14)
Thioalkylated Meldrum 's acid is easily by treatment of Meldrum 's acid with an aldehyde and thiophenol in the presence of catalytical amounts of piperidinium acetate (→ 1–6 , Table 1 ). The adducts 1–6 are crystalline, ...
Syngas and HDS catalysts derived from sulphido bimetallic clusters
(Elsevier, 1988)
The clusters, CP2'Mo2Fe2S2(CO)8 (MoFeS) and Cp2'Mo2CO2S3(CO)4 (MoCoS) (Cp' = [eta]-C5H4Me) have been supported on the refractory oxides, Al2O3, SiO2, TiO2, and MgO, and subjected to temperature programmed decomposition ...
Subsolidus phase relationships in part of the system Si, Al, Ca/N, O
(Elsevier, 1988)
Subsolidus phase relationships in the region bounded by Si3N4, SiO2, CaSiO3, 2CaO.Al2O3.SiO2, CaO.Al2O3, Al2O3 and [beta]'-Si2Al4O4N4([beta]60) have been studied. A new quinary phase with composition near to CaO. 1[middle ...
Selective oxidation of methane over vycor glass, quartz glass and various silica, magnesia and alumina surfaces
(Elsevier, 1988)
The reaction between methane and oxygen was investigated in empty Vycor glass and quartz tubes and over various silica compounds in powder form. In the temperature range of 893-993 K and with methane-to-oxygen ratios close ...
Purification of cytidine-triphosphate synthetase from rat liver, and demonstration of monomer, dimer and tetramer
(Elsevier, 1988)
Cytidine-triphosphate synthetase (UTP: ammonia ligase (ADP-forming), EC 6.3.4.2.) has been purified over 31 000-fold to homogeneity with 17% recovery from rat liver cytosol, using high-performance liquid chromatography ...
The effect of glycosidases on the survival of rat erythrocytes in circulation
(Elsevier, 1988-07-15)
Enzymic removal of sialyl groups from mammalian erythrocytes resulted in their rapid sequestration from circulation subsequent to autologous transfusion. It has been demonstrated by many investigators that the terminal ...
