Effect of adsorbents on degradation of toxic organic compounds by coimmobilized systems
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-15)
The use of coimmobilized systems for treatment of toxic organic compounds has been proposed. The proposed approach combines the use of adsorbents and laboratory identified microorganisms immobilized in a protective permeable ...
The effect of 2,2'-dichlorodiethyl sulfide on DNA synthesis of a murine stratified keratinocyte culture system
(Elsevier, 1992-09-28)
A primary stratified keratinocyte culture resembling the epidermis in situ was used as a model for studying the effects of exposure to 2,2'-dichlorodiethyl sulfide, or sulfur mustard (SM), on DNA synthesis. A method that ...
Comparison of heat capacities measured by adiabatic calorimetry and by scanning calorimetry: thermodynamic properties of 9-methylcarbazole at temperatures between 4 K and 345 K
(Elsevier, 1992-03)
We have measured the heat capacity of 9-methylcarbazole at 4[less-than-or-equals, slant]T/K[less-than-or-equals, slant]345 by adiabatic calorimetry and compared it with that measured by differential scanning calorimetry ...
Continuous photoautotrophic cultures of the eukaryotic alga chlorella vulgaris can exhibit stable oscillatory dynamics
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-05)
Sustained oscillations in cell concentration, average per cell DNA content, and average cell size were found in continuous photoautotrophic cultures of Chlorella vulgaris at low dilution rates (0.1/day). The period of ...
A yeast artificial chromosome contig encompassing the type 1 neurofibromatosis gene
(Elsevier, 1992-07)
The yeast artificial chromosome (YAC) system (Burke et al., 1987, Science 236: 806-812) allows the direct cloning of large regions of the genome. A YAC contig map of approximately 700 kb encompassing the region surrounding ...
The thermochemical and thermophysical properties of Cs2RuO4 and Cs2MnO4 at temperatures from 5 K to 1000 K
(Elsevier, 1992-08)
Low-temperature heat capacities from 5 K to 350 K by adiabatic calorimetry and high-temperature enthalpy increments above T = 450 K to 800 K by drop calorimetry of Cs2RuO4 and Cs2MnO4 have been measured. The two compounds ...
A small plasmid for recombination-based screening
(Elsevier, 1992-12-01)
We reported recently the construction of the 4.4-kb RoK-derived pMADI plasmid carrying supF [Stewart et al., Gene 106 (1991) 97-101] that does not share nt sequences with Co1E1 and therefore permits recombination-based ...
A 530kb YAC contig tightly linked to the Friedreich ataxia locus contains five CpG clusters and a new highly polymorphic microsatellite
(Springer-Verlag, 1992-07)
Friedreich ataxia (FA) is a severe autosomal recessive neurodegenerative disease. The defective gene has been previously assigned to chromosome 9q13-q21 by demonstration of tight linkage to the two independent loci D9S15 ...
Effect of calcium chloride treatment on hybridoma cell viability and growth
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-10)
In order to minimize hybridoma cell damage during calcium alginate entrapment, the effect of calcium chloride treatment on hybridoma cell viability and growth was studied in terms of calcium chloride concentration and ...
