ISSN: 1471-0528Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Serum and amniotic fluid samples from five pregnant women were analyzed for different proteinase inhibitors by ion-exchange chromatography on DEAEcellulose. Alpha-2 macroglobulin was found to be absent in amniotic fluid. Even though α-1 antichymotrypsin was identified in amniotic fluid, its concentration gradient between serum and amniotic fluid (20–60) was much higher than that of α-1 antitrypsin (8–20). Two forms of α-1 antitrypsin were identified in both the fluids. In pregnancy, the ratio of the two forms was altered in favour of the less anionic form compared to normal sera. The contribution of the heat stable proteinase inhibitor for total antitryptic activity in amniotic fluid was more than in serum. The observation that urine samples from immature infants had higher heat stable inhibitory activity than urine samples from normal infants suggests that the heat stable inhibitor in amniotic fluid may arise from fetal kidney.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The current study was undertaken to explore the possibility of detecting hydrogen cavitation in magnetic materials through magnetic property measurements. It is known that dissolved hydrogen in a material causes microvoids. These voids may affect the structure-sensitive magnetic properties such as coercivity and remanence. In this study, hydrogen was introduced into nickel and iron by two processes, namely thermal charging and cathodic charging. The effect on the magnetic properties was measured. In addition, the variation of the magnetic properties with porosity was studied. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: An extension to the model of hysteresis has been presented earlier which included the effect of anisotropy in the modeling of the anhysteretic magnetization curves of uniaxially anisotropic single crystalline materials. Further exploration of this extension shown here considers different kinds of crystal anisotropy in materials. Theory considers that the differential susceptibility at any given field is determined by the displacement of the prevailing magnetization from the anhysteretic magnetization. Thus, it has been shown that the effect of anisotropy on magnetic hysteresis in materials can be incorporated into the model of hysteresis through the anisotropic anhysteretic. This extension is likely to be particularly useful in the case of hard magnetic materials which exhibit high anisotropy. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1574-6968Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: Abstract Luminous bacteria harboured in the skin, gill and gut of the fishes Mugil cephalus and Tachysurus arius were studies. Within the gut, the distribution of bacteria was studied regionwise, i.e., foregut, midgut and hindgut. In M. cephalus, maximum luminous bacterial population density was observed in the hindgut and minimum was found in the foregut. In T. arius, maximum luminous bacterial population density was recorded in the hindgut and minimum was found in the midgut. Luminous microflora associated with the host showed seasonal variation. Bacterial load of the surrounding medium and type of food governed the distribution of luminous microbiota in fish. Vibrio harveyi and V. fischeri were the two species identified, the former accounting for the majority of the isolates.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-4475Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract In our previous communication1, we have reported the dipole moment of Cu(II) oleate evaluated by the method given byDasgupta andSmyth 2. In this paper the dielectric constants ε′ and dielectric losses ε″ of Cu(II) stearate in benzene, have been reported and the dipole moment values of the salt have been calculated by the methods described byGopalkrishna 3 andDasgupta andSmyth. The dipole moment of Cu(II) stearate by the former method comes out to be µ34 2.71, µ50 2.14, µ70 2.26 and by the latter method µ34 2.27, µ50 1.74, µ60 2.57, and µ70 2.73. The reliability of the Multi-Dekameter, DK-06 used was tested by measuring the dipole moment of nitrobenzene according to the method ofGopalkrishna 3.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1432-0703Source: Springer Online Journal Archives 1860-2000Topics: Energy, Environment Protection, Nuclear Power EngineeringMedicineNotes: Abstract The residue levels of persistent organochlorines, such as HCH (BHC: 1,2,3,4,5,6-hexachlorocyclohexane) isomers, DDT [1,1,1-trichloro-2,2-bis (p-chlorophenyl) ethane] compounds, PCBs (polychlorobiphenyls) and HCB (hexachlorobenzene), were measured in wildlife. The wildlife were sampled from terrestrial and aquatic habitats in and around the agricultural watershed of Parangipettai, South India. On the basis of overall concentrations ∑HCH ranked first followed by ∑DDT, ∑PCB and HCB, reflecting the increasing usage of HCH in recent years in India. The residue levels of organochlorines in birds varied according to their feeding habits and showed the following pattern: inland piscivores and scavengers 〉 coastal piscivores 〉 insectivores 〉 omnivores 〉 granivores. High levels of HCH and DDT residues were recorded in Pond heron and Cattle egret which feed in the agricultural fields. Comparison of HCH concentrations in fish and birds in the study area to other locations was made to further understand the dynamics of contaminant accumulation in tropical wildlife. Regarding birds, a wide variation in residue levels could be seen among various countries, with tropical regions registering high levels. In contrast, the variation is not prominent in the case of fish. The residue levels in fish measured in the present study were generally comparable to values reported from other locations. This suggests that the bioavailability of contaminants to the aquatic fauna is less due to the smaller flux and shorter residence time of these chemicals in the tropics.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-184XSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Qualitative and quantitative investigations were made on the luminous bacteria associated with the gut of pond cultured milk fishChanos chanos. Significant differences in luminous bacterial numbers were found between gut and pond water and between gut and pond sediment, but not between pond water and sediment. No significant variation in luminous bacterial population among the gut regions was observed. The quantity of ingesta in the fish gut does not appear to influence the biomass of luminous bacteria.Vibrio harveyi andV. fischeri were the 2 most commonly encountered species, and of the 2 luminous species,V. harveyi was predominant.Type of Medium: Electronic ResourceURL: -
