Published 1990Staff ViewISSN: 1573-0832Keywords: fungal diarrhoea ; IndiaSource: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Abstract A total of 854 patients (640 children and 214 adults) admitted with acute or chronic diarrhoea suspected of non-invasive overgrowth of fungi in intestine were screened during a period of 3 years. Fungal proliferation was noted in 54.8% of these patients (53.6% in children, 58.4% in adults). The predominant fungal species isolated were Candida albicans (64.5%), followed by C. tropicalis (23.3 %) C. krusei (6.9%), Torulopsis glabrata (1.6%). Trichosporon sp. and Geotrichum sp. were found to be responsible in 2.3% of adults. As seen in bacterial diarrhoea, higher incidence was noted in children from April to August. No such seasonal variation was noted in adults.Type of Medium: Electronic ResourceURL: -

ISSN: 1588-2861Source: Springer Online Journal Archives 1860-2000Topics: Information Science and LibrarianshipNature of Science, Research, Systems of Higher Education, Museum ScienceNotes: Abstract On the basis of survey, conducted within the framework of the UNESCO International Comparative Study on the Organization of Research groups, the role and position of women in scientific activity is compared. Data on a total of (6000 individuals) from Argentina, India, Egypt, Korea, Poland and USSR show that women scientists' participation is highest in Poland, and lower in India, Korea and Argentina. Everywhere women scientists are more often doing the routine aspects of the research process and more isolated from external contacts with men. Women have lower scientific productivity than male scientists which can be interpreted as a consequence of their lower status in the organization.Type of Medium: Electronic ResourceURL: -

Appreciable yields of polymer from octamethylcyclotetrasiloxane liquid have also been obtained. These results were achieved on “ultra-dry” monomers and are interpreted in terms of an ionic polymerization mechanism.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0021-8995Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyMechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsPhysicsNotes: The HBr-initiated solid-state polymerization of hexamethylcyclotrisiloxane has been investigated. Up to about 70% conversion, the rate of polymerization is found to be constant but the molecular weight of the polymer formed was observed to increase with conversion. Temperature did not have a marked effect on the polymerization rate as an activation energy of only 2.8 kcal/mole was observed, whereas the rate was found to be exponentially related to the HBr vapor pressure. The HBr and the radiation-initiated solid-state polymerization are compared.Additional Material: 4 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0021-9304Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: MedicineTechnologyNotes: In vitro enzymatic degradation of nonporous films of segmented poly(etherurethane) (Pellethane 2363-80AE) was investigated by incubating the biomaterial in concentrated trypsin solutions for 5 months at room temperature. Chemical degradation of films was monitored by surface analysis techniques such as Fourier transform infrared spectroscopyattenuated total reflectance and electron spectroscopy for chemical analysis. This latter technique proved to be much superior in detecting chemical changes. Extraction of films with methanol and characterization of the extracts by gel permeation chromatography revealed the presence of low-molecular-weight polymers. Results have shown that trypsin has the ability to induce degradation in PEU, the soft segment being most affected, particularly the CH2—O bond of the either linkages.Additional Material: 7 Ill.Type of Medium: Electronic ResourceURL: -

Published 1988Staff ViewISSN: 0021-9304Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: MedicineTechnologyNotes: Anhydrous ammonia gaseous plasma technique was used for the surface modification of polypropylene beads. Amino groups were added onto the surfaces of beads by exposing them to ammonia plasma. Through these amino groups covalent immobilization of glucose oxidase and peroxidase were carried out. The total amounts of immobilized glucose oxidase and immobilized peroxdase were found to be 52 and 43 μg/cm2, respectively. To assess the stability of enzyme-polypropylene linkage, beads with covalently immobilized glucose oxidase and peroxidase were washed with phosphate buffer. It was found that after the removal of the adsorbed enzymes, the concentration of covalently immobilized enzymes tended to reach a steady state. After additional washing with buffer for 5 to 6 h, 40-55% of the immobilized enzymes were found to be in the active form.Additional Material: 2 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0360-6376Keywords: Physics ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The concentration of water in purified and BaO-dried α-methylstyrene was found to be 1.1 × 10-4M. The radiation-induced bulk polymerization of the α-methylstyrene thus prepared was studied in the temperature range of -20°C to 35°C. The polymerization rate varied as the 0.55 power of the dose rate. The theoretical molecular weights and molecular weight distribution were calculated from a proposed kinetic scheme and these values were then compared with those found experimentally. The agreement between these two was reasonably close, and therefore it was concluded that, from the molecular weight distribution point of view, the proposed kinetic scheme for the cationic polymerization of α-methylstyrene is an acceptable one. The rate constant for chain transfer to monomer kf changed with temperature and was found to be responsible for the decrease in the molecular weight of the polymer with increase in temperature. kf and kp at 20°C were found to be 0.95 × 104 l./mole-sec and 0.99 × 106 l./mole-sec, respectively.Additional Material: 5 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0449-296XKeywords: Physics ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The solid-state polymerization of hexamethylcyclotrisiloxane has been shown, by means of specific ion scavengers, to proceed by a cationic process. The reaction occurs at the crystal surface rather than within the lattice and exhibits a polymerization rate which is inversely proportional to the defect and negative ion concentrations in the crystalline monomer.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL:
