Abstract

Increasing knowledge regarding the impact of diet on human health along with state-of-the-art technologies has led to significant nutritional discoveries, product innovations and mass production on an unprecedented scale. The ocean is a largely unexplored treasure chest of pharmaceuticals, nutraceuticals and products for human health. Marine products continue to gain in worldwide popularity as they are being successfully utilized for in a wide range of human health benefits. The world's marine environment constitutes the greatest diversity of nutrients found on the planet. A number of plant and animal species are commonly used as food sources and are known to produce a vast array of chemical components that can be and are developed into nutraceutical ingredients with beneficial medicinal uses. The marine environment represents a relatively untapped source of functional ingredients that can be applied to various aspects of food processing, storage and fortification. Although large numbers of novel compounds have been isolated from marine organisms and many of these substances have pronounced biological activity, only very few have been marketed as pharmaceutical products. The exploration of the potential of marine biodiversity is still at a very early stage and requires the development of co-ordinated infrastructures as well as close collaboration between government, biotech industries and academia.

Abstract

Monolauryl and monostearyl phosphoric acid esters were synthesized by phosphorylation of the corresponding long chain fatty alcohols which were subsequently neutralized with mono-, di- and tri-ethanolamines. Monoalkyl nature of phosphate derivatives was ascertained by evaluating phosphorus contents. All the phosphate derivatives displayed appreciable lowering of surface tension of water and the monoethanolamine compounds, in particular, showed lower CMC values compared to the conventional anionic surfactant, linear alkyl bezene sodium sulphonate. Monoethanolamine derivatives of lauryl and stearyl esters of phosphoric acid exhibited lower water solubility compared to diethanolamine and triethanolamine derivatives. Foam characteristics of all the compounds were, in general, poor. Monolauryl diethanolamine phosphate ester indicated superior wetting power.

Abstract

The main objective of the present article is to give a unifying approach to most of the paranormed difference sequence spaces defined in the domain of weighted mean operator. In this work, we introduce certain new paranormed spaces such as l_∞(μ, ν; Δ^r, p), c₀(μ, ν; Δ^r, p), c(μ, ν; Δ^r, p) and l(μ, ν; Δ^r, p) by combining the generalized difference operator Δ^r and the weighted mean operator G(μ, ν). Also we investigate their topological structures and establish their α-, β- and γ- duals. Moreover we characterize the matrix transformations from these spaces to the basic sequence spaces l_∞(q), c_o(q), c(q) and l(q).

Abstract

This paper presents the basic concept of reliability applicable to Mechanical Engineering. The paper also includes the results obtained and the conclusions drawn from the computer aided reliability analysis of equipment of thermal power plant done by the authors as an example of how to use the theories of reliability in actual engineering practice. However, in reality in the operation and maintenance of a plant errors arise out of a quite specific combination of conditions in the man-machine system and it is on the total system that the attention is centered.

Abstract

ZnS nanobelts and ZnS@reduced graphene oxide (rGO) nanocomposites were synthesized via simple solvothermal treatments. The chemical composition, structure and optical properties of ZnS nanobelts and ZnS@rGO nanocomposites samples were characterized by X-ray diffraction (XRD),Raman Spectroscopy and FESEM, UV-visible spectroscopy. We have used UV-Visible absorption spectra to find the optical band gap of prepared ZnS nanobelts and ZnS@rGO nanocomposites, direct bandgap of pure ZnS is 2.70 eV and that in case of ZnS@rGO is about 2.59 eV. The bandgap of pure ZnS nanostructure differ significantly from bulk ZnS due to the quantum confinement effect in nanostructure. ZnS nanostructure and ZnS@rGO nanocomposites were used as a photocatalyst for the degradation of methylene blue (MB) under visible light irradiation.

Abstract

Cowa (Garcinia cowa Roxb.) locally known as Kujithekera belongs to the family Clusiaceae is one of the popular indigenous fruits of north eastern region of India. The fruit is having commercial and medicinal values. It is the source for a natural diet ingredient hydroxycitric acid (HCA) which is an anti obesity compound. Kujithekera fruits are highly perishable in nature having short shelf-life which reduces the commercial values of the fruit. Extension of shelf-life using 5 different treatments was studied. The treated fruits were packed in transparent perforated (0.2% ventilation) low density polyethylene bags (25μ). The physico-chemical qualities of the treated fruits were found to decrease significantly with the advancement of storage period. Fruits dipped in 1 per cent wax emulsion for 5 min, air dried and packed in transparent perforated (0.2% ventilation) LDPE bags (25μ) retained the highest ascorbic acid (7.95 mg and 5.27 mg/100g), total sugar (6.3% and 3.72%), total phenol (1.2g and 1.96g/100g), hydroxycitric acid (6.20g and 6.67g/100g), energy value (39.95Kcal and 27.37Kcal/ 100g) both in pulp and peel, respectively on 6 days after storage. The wax coated fruits remained firmer (1.66 kg/cm2) and recorded the highest CIE lab parameters like L*, a*, b* and C* (45.73, 24.61, 13.02 and 27.84, respectively) with an extended shelf-life of 6 days at ambient conditions (29.8±1.1°C, RH 79.6±3%).

Abstract

Kujithekera (Garcinia cowa Roxb), commonly known as Cowa is a sub-tropical minor fruit grows well in Assam. Fruits are juicy having sub-acid taste and suitable for preparation of jam and pickles, sundried slices given in dysentery as medicine. An attempt was made to understand the changes in physico-chemical qualites of Kujithekera fruit during storage at ambient temperature (Mean temp 29.8°C, Mean RH 79.6%) for 6 days at an interval of two days. The physico-chemical changes of the fruit during storage using five different treatments were studied. There was significant increase in physiological loss in weight with advancement of storage period. The bio-chemical qualities of the treated fruits like TSS, crude protein, fat, ash were found to decrease significantly with the advancement of storage period. The fruits treated with 1 per cent wax emulsion retained the highest TSS, both in pulp and peel on 6 days after storage. The fruit pulp qualities like crude protein, fat, ash, total phenl were almost same in wax coated fruits and CaCl₂ treated fruits on 6 days after storage.

Abstract

The classification of agroclimatic zones in India was made in the 1990s for identifying priorities and developing strategies for location-specific and need-based research as well as overall agricultural development in the country. Long-term climatic parameters, particularly temperature and rainfall along with soil and crop information were used for the classification of agroclimatic zones. It has been documented with a fair degree of accuracy that overall climate is changing, particularly with respect to temperature over the Indian region. Thus it is anticipated that in the recent past, climate change may be reflected in the agroclimatic zones as well and ultimately affect the criteria of their classification based on climatic parameters. The objective of the present study is to examine the trends and spatial/temporal variability of temperature, rainfall, rainy days, and heavy rainfall in different agroclimatic zones of the country, which may help in better understanding of the further initiatives on reclassification of agroclimatic zones, if required. Using various long-term gridded data from 1985 and instrumental datasets starting from 1951 to 1980, studies have been made to observe changes in different components of the climatic variables, i.e. temperature and rainfall. It has been observed that there are significant changes in temperature and rainfall, both temporally and spatially, across India and there is a definite shift in temperature and rainfall patterns in the recent past compared to 1951–1980. It has also been inferred that there is a need to reconsider the classification of agroclimatic zones in India under the scenario of observed climate changes in the country.

Abstract

It is an acknowledged fact that optimum plant capacity utilisation is directly related to the maintenance factor of the plant and machinery. A very conservative estimate of our investments in plants, machinery and equipment puts the figure at about Rs. 25,000/- crores. Even a bare minimum expenditure of 3% on maintenance will result in an annual maintenance expense of Rs 750/- crores. This is a significant amount if we take into consideration the capital inflow needed for expansion of industrial activity in our country. In this era of high technology and increasing sophistication, there is no escape from investment in capital intensive plant and machinery if we desire to catch up and keep pace with the developed countries of the world. This means more expenditure on maintenance and likely increase in loss if maintenance activities are not properly organised and brought up to date. Routine inspection and programmed overhauls will not enable ui to increase plant availability and capacity utilization and cut down costs.
