Mycorrhizal Dependency in Certain Indian Cotton Cultivars

Mycorrhizal dependencies of ten cotton cultivars were evaluated in the green houseusing completely randomized block design model. Acid-delinted seeds were sown inpolybags containing natural black soil. Plant growth, nutrient content and mycorrhizalcolonization levels were studied. Cotton cultivars exhibited mycorrhizal colonizationranging from 36.52 to 73.5 %. Plant dry weight and tissue Nitrogen content were positivelycorrelated whereas tissue Potassium was not correlated with the mycorrhization. Rootdiameter, number of root hairs and root length were varied among the cultivars. Rootdiameter was highest in the cultivar NHH 44, whereas root hair number was more in Suvin.Root hair length was maximum in the cultivar Suvin. Mycorrhizal dependency wasnegatively correlated with root hair number and root hair length. Maximum mycorrhizaldependency was exhibited by the cultivar Surya. The results showed the existence of strongmycorrhizal dependency in the cotton cultivars

2, 4-Dimethyl-6-hydroxyacetophenone oxime and 3, 5-dibromo-2, 4-dimethyl-6- hydroxyacetophenone oxime as reagents and diethylamine as a synergist in the extraction and separation of metals

1022-10242,4-Dimethyl-6-hydroxyacetophenone oxime and 3,5- dibromo-2,4-dimethyl-6-hydroxyacetophenone oxime act as very good reagents for the extraction and separation of Cu(II), Ni(II), Co(II), Fe(III) and Mn(II). Addition of diethylamine as a synergist in the extraction system, not only increases the per cent extraction of the metals but also the molar absorbances of the complexes. The separation of the metals from one another, viz., Cu(II) from Ni(II), Cu(II) from Co(II) and Cu(II) and Ni(II) from Cr(III) becomes far more easier in the presence of diethylamine

Fuzzy Computing for Control of Aero Gas Turbine Engines .

Many methods, techniques and procedures available for designing the control system of plants and processes, are applied only after knowing accurately the plant or process to be controlled. However, in some complex situations where plants/processes cannot be accurately modelled, and especially where their control has human interaction, controller design may not be completely satisfactory. In such cases, it has been found that control decisions can be made on the basis of heuristic/linguistic measures or fuzzy algorithms. Fuzzy set principles have been used in controlling various plants/processes ranging from a laboratory steam engine to an autopilot, including an aero gas turbine engine engine for which the response of the engine speed for a fuzzy input of fuel flow has been studied. In this paper, certain stipulations and logic are suggested for the control of the total gas turbine engine. A case study of a single spool aero gas turbine engine with one of its state variables varied by heuristic logic is presented

HLA-DR and -DQ antibodies in the sera of South India Parous women

HLA-A, -B positive sera of south Indian parous women were screened for the presence of HLA-DR and -DQ antibodies. The sera were absorbed with pooled platelets in a micro-method and screened against HLA-DR and -DQ typed B-lymphocytes panel. Out of fifty two sera, twenty were found to contain HLA-DR and -DQ antibodies. Seven sera were demonstrated to be specific for well defined DR and DQ antigen

Review of harm-benefit analysis in the use of animals in research

This is the final version of the report. Available from the Home Office via the link in this recordReport of our review of the processes of harm-benefit analysis (HBA) carried out under the UK Animals (Scientific Procedures) Act 1986 (A(SP)A).Report of the Animals in Science Committee Harm-Benefit Analysis Sub-Group chaired by Professor Gail Davies. The Animals in Science Committee Harm-Benefit Analysis subgroup, chaired by Professor Gail Davies, has produced a review of the harm-benefit analysis (HBA). This review is an analysis of the underpinnings and implementation of the HBA which remains a crucial step in the justification of the use of animals in science. It is published in response to a ministerial commission.Animals in Science Committe
