Effects of Wood Preservatives on Physical Properties of Wood II. Effects of Different Salt Loadings of Copper-Chrome-Arsenic Composition

Effect of different salt loadings of copper-chrome-arsenic (CCA) preservative on shrinkage, swelling, and equilibrium moisture content at various relative humidities has been reported for Pinus roxburghii and Mangifera indica. At very low salt retentions, treated wood shows excessive shrinkage and swelling, which reaches a maximum and then falls off with increasing salt loadings. The two woods differ as to the position of these maxima. At higher retention levels, shrinkage and swelling are reduced, but the wood becomes more hygroscopic. The increased hygroscopicity is probably due to CCA salt and the additional water is held by the salt molecules deposited in the cell lumens. At low salt retentions, equilibrium moisture content is lowered at all relative humidities. The general sigmoid character of the adsorption curves is maintained at all levels of retentions

The Effect of Oxidation on the Tribological Performance of Few Vegetable Oils

BackgroundThe use of vegetable oils and their derivatives as lubricant base oils are ever increasing because of sustainability issues and in the context of conservation of nature as they are biodegradable and environmentally friendly. The one disadvantage which is of concern with vegetable oils is their limited oxidative stability.ObjectivesTo study the effect of oxidation on the tribological performance of few vegetable oils by subjecting the oil samples to accelerated ageing in a dark oven at different temperatures, inducing the oxidation under controlled conditions.MethodOils were stored at an elevated temperature in an oven under dark condition and the oxidized oil samples were analyzed in terms of various properties.Results and conclusionsThe samples were analyzed for the changes in viscosity, percentage of free fatty acid, peroxide number and were compared with fresh oils samples. Further tribological property was also evaluated and the observed differences were linked to formation of oxidation products like peroxides, kinetics of the oxidation with reference to ageing temperature

Mid Day Meal Scheme: Understanding Critical Issues with Reference to Ahmedabad City

Problems of illiteracy, malnutrition, anaemia, vitamin-A and iodine deficiency are very common among children in India. In 2001 Supreme Court of India ruled that state governments must provide mid-day meal (MDM) to children of government assisted primary schools. The 2007-2008 budget of the central government has allocated about Rs. 73 billion for the MDM scheme. Therefore, it becomes imperative that a comprehensive evaluation of the programme be undertaken to judge its efficacy. We studied the implementation of the scheme, made field visits to schools to document food preparation and delivery, and collected meal samples to test them in laboratory for nutritional contents and food safety. Study seems to indicate that the implementation of the scheme may be wanting on the grounds of nutrition and food safety. For example, protein and iodine content is not sufficiently provided by the meals. Raw food samples contained uric acid levels higher than stipulated by food laws. Traces of aflatoxins were also found. Food safety may be improved by employing food safety systems such as HACCP, contracting out meal preparation and distribution to reputed private parties, and offering packaged foods which also provide variety. Offering nutrition bars and fruits such as banana not only will ensure delivery of hygienic food but it will enhance the nutrition delivery of the MDM scheme.

Reduction of vibration transmission and flexural wave propagation in composite sandwich panels

Doctor of PhilosophyDepartment of Mechanical and Nuclear EngineeringLiang-Wu CaiX. J. XinThin walled structures such as plates and shells have application in many fields of engineering because these structures are light weight and can support large loads when designed suitably. In real world, loads may cause these structures to vibrate which can be undesirable causing fatigue and failure of the structure. Such undesirable vibrations need to be reduced or eliminated. In this work, analytical studies of flexural wave propagation for idealized geometries are conducted and finite element method (FEM) is used to explore the effects of composite panel designs of finite size for the reduction of vibration transmission. In the analytical studies, the influence of the material properties on the reflection and transmission characteristics are explored for an infinite bi-material plate, and infinite plate with a strip inhomogeneity. In the analytical study of an infinite thin plate with a solid circular inclusion, the far and near field scattering characteristics are explored for different frequencies and material properties. All the analytical studies presented here and reported in the literature consider infinite plates to characterize the flexural wave propagation. Obtaining closed form solutions to characterize the flexural wave propagation in a finite plate with inclusions is mathematically difficult process. So, FEM is used to explore the composite panel designs. The understanding gained about the material properties influence on the flexural wave propagation from analytical studies helped with the choice of materials for FEM simulations. The concept of phononic crystals is applied to define the design variations that are effective in suppressing vibration transmission. Various design configurations are explored to study the effects of various parameters like scatterer’s material properties, geometry and spatial pattern. Based on the knowledge gained through a systematic parametric study, a final design of the composite sandwich panel is proposed with an optimum set of parameters to achieve the best vibration reduction. This is the first study focused on reducing vibration and wave transmission in composite rotorcraft fuselage panels incorporating the concept of phononic crystals. The optimum sandwich panel design achieved 98% vibration transmission reduction at the frequency of interest of 3000 Hz

Fishery, biology and stock assessment of spotted seer, Scomberomorus guttatus (Bloch & Schneider) off Andhra Pradesh

The fishery, biology and stock of the spotted seerfish, Scomberomorus guttatus (Bloch & Schneider) along Andhra Pradesh was studied during 2012-2014. The annual average landing of spotted seer during the period along Andhra coast was 2,614 t. Major contributors were trawlnets-1,104 t (42.2%) and gillnets-950 t (36.3%). Catches were higher during August-December. Length-weight relationship varied significantly between males, females and indeterminates. Growth was isometric in males and allometric in females and indeterminates. Overall sex ratio was 1:1.87. Length at first maturity was 38.9 cm. Peak spawning was observed during November-April. Higher Gonadosomatic index coincided with periods of peak spawning. Mature ovaries contained both maturing (0.41 mm-0.70 mm) and matured (0.71 mm-0.90 mm) ova. von Bertalanffy growth equation was Lt = 71.98 [1-e -0.23 (t + 0.0722)]. Natural mortality, fishing mortality and total mortality were 0.54, 0.49 and 1.03. Exploitation ratio was 0.48. Annual total stocks, biomass and Maximum Sustainable Yield were 8,546 t, 5,335 t and 2,747 t. A minor increase in yield and yield/recruit is possible by increasing the present level of fishing by 20%

Trophodynamics of Nemipterus japonicus (Bloch, 1791) in the trawl landings along the north-east coast of India

The trophodynamics of Nemipterus japonicus (Bloch, 1791) along the north-east coast of India was studied during 2012-2015 based on specimens collected from trawl landings at Digha, Paradeep (northern region), Visakhapatnam and Kakinada (southern region). Crustaceans were the preferred prey with index of relative importance (IRI) of 50% in the northern region and 42.4% in the southern region. Among crustaceans, Oratosquilla dominated in both the regions followed by crabs and several species of penaeids and nonpenaeids. Finfishes ranked next in importance (IRI% of 32.1 in northern region and 39.9 in southern region) and included Stolephorus spp., silverbellies, Coilia sp., other clupeids, Apogon spp., mackerel, sardines, eels, priacanthids, Bregmaceros sp. and sciaenids. Along northern region, in juveniles and preadults, the diet comprised chiefly of crustaceans (IRI% of 72.27 and 52.76), followed by finfishes (IRI% of 15.37 and 27.65). In the southern region, adult fishes exhibited higher preference for finfishes (IRI% of 47.5 to 62.8). Feeding intensity was low throughout the year with close to half (48.23% in northern region and 43.67% in southern region) of the fishes exhibiting empty or trace stomach conditions which increased with an increase in age and size of fish. High similarity of 75.54% in the northern and 84.19% in the southern region was recorded in the diet contents of smaller and moderate sized adults. Annual and seasonal mean similarity in the diet components between the regions was 69.9 and 53%. Prey contents in juveniles between both the regions exhibited a similarity of 59.5%, while preadults and adults recorded similarities of 62.7 and 68.2% respectively

Electrical and Magnetotransport Properties of Canted Antiferromagnet Dy₅Si₂Ge₂

Summary form only given. Since the giant magnetocaloric effect is encountered in a ferromagnetic Gd5Si2Ge2 alloy near room temperature it is considered as a suitable material for magnetic refrigerator applications. Also a commensurate structural transition occurs at the magnetic transition temperature and there is a good correlation between the crystal structure and magnetic properties. Such observations have triggered numerous experimental studies on similar rare earth alloys and compounds. We have synthesized its Dy- analogue, namely, Dy5Si2Ge2 and have characterized it by means of room temperature X-ray diffraction, ac magnetic susceptibility (15 K - 300 K), electrical resistivity (at zero field and at 6 T), thermoelectric power (15 K - 300 K) and neutron diffraction (at 300 K and 9.2 K) experiments
