Abstract

There has been a substantial increase in the number of natural and man-made disasters, both in scope and intensity, in the last few decades. The resultant damage - social, economic, and human, has highlighted the necessity of immediate response, in aid of maximum number of affected people, utilising all available resources in an optimal manner. The logistical challenges in the face of such disasters, call for proper management of relief resources in the form of Human Relief Supply Chain (HRSC). This study examines current issues regarding HRSCs including major stakeholders and agencies involved, including role of the private sector, and their respective contributions. A framework of HRSC in the Indian context is proposed, highlighting major issues and challenges.

Abstract

The effect of compressive strain on the thicknesses of concentrically folded beds is discussed. Two sets of graphs have been given illustrating the thickness variation due to compression. If the fold axis is parallel to one of the principal axes of strain the two dimensional strain on the profile plane can be directly determined from these graphs. When this is not so the numerical value obtained from the graphs will only give a qualitative idea of the two dimensional strain. If the fold axis has got a uniform orientation in space it will not be possible to determine the three dimensional strain from thickness measurements. Equations have been given by which the three dimensional strain can be computed if the fold axis has a variable orientation.

It has been shown that in compressed concentric folds there is a critical value of θ (θ being the angle between the bedding plane and the normal to the axial plane), below which the fold will show a nearly perfect similar geometry. If in natural compressed concentric folds the maximum value of θ observed falls below this critical value the fold will show a similar geometry. Thus, it is possible to produce similar fold by compressing an initially concentric one.

Abstract

The deformed pebbles in the conglomerate show a large variation in the orientation of their longest axes as well as in the values of the axial ratios a' and b'. This has been interpreted as due to a nonspherical nature of the original pebbles. The effect of deformation has been separated from the effect of the original shape. It has been shown that a superficial analysis of the shape of deformed pebbles may give a wrong idea about the state of strain in the rocks, and the method by which the true amount of strain can be computed from dc:formed pebbles has been discussed.

Abstract

The wholerock Rb-Sr isochron age of 2380 &#177; 44 Ma (Sr<SUB>i</SUB> = 0.70492  &#177; 14) obtained for the Sambalpur granodiorite indicates an Early Proterozoic granitic activity in this region younger than Singhbhum Granite (ca. 3.3 to 3.1 Ga). Comparable Rb-Sr ages have also been reported for different granites from Mandhya Pradesh.

Abstract

A study under four different eco-systems (forest land, agricultural land, tea garden and fallow land) was conducted under Terai situation of West Bengal to characterise the soils with important physico-chemical properties and also to find out the available nutrient status in soils with the increasing depth. It was observed that the available N-P-K of the soils and the exchangeable (Ca⁺² + Mg⁺²), electrical conductivity (EC), oxidisable organic carbon (OC) and total C-H-N-S in soil significantly varied with the depth of soils in most of the cases. The soils were acidic in reaction and non-saline in character. The available N-P-K and OC of soils of forest, agricultural and tea-garden differed with the uncultivated fallow. The survey of the regions showed that the buildup of nutrients (N-P-K, Ca⁺² + Mg⁺²) varied with the changing ecosystems as reflected by the C/N, C/S and C/H ratio of the soils.

Abstract

Indian automotive industry has increasingly adopted global supply chain best practices including supplier relationship as a management imperative, in the last two decades. Increased competition, globalisation, wide-spread outsourcing, use of information technology and rapid technological advances have contributed in supplier relationship development with the objective to achieve competitive advantage and a high level of performance. It is evident that only if mutual benefits accrue to both Vehicle Assemblers (VA) and their suppliers, the partnership between them would be meaningful and effective. Also, VAs have necessarily, to invest considerable resources and effort in achieving collaboration with their suppliers and cost-effectiveness becomes an issue which leads to supply base rationalisation and a segmented approach. Therefore understanding the issues involved and identifying focus areas for successful supplier relationships becomes an imperative. This paper , based on an exploratory study, delves into the VA- supplier interface in Indian automobile supply chains, examines various theoretical and practical dimensions, in order to identify strategic imperatives (key impact drivers), Supplier Management Orientation (SMO) of VAs, adoption of Supplier Development Practices, extent of VA- supplier partnerships and mutual benefits accruing to both entities. Based on this a framework for holistically studying the VA-supplier interface is proposed.

Abstract

SHRIMP U-Pb analyses of zircon grains from two thin dark shales believed to be syndepositional ashfall tuffs close to the base of the banded iron-formation (BIF) within the Mulaingiri Formation of the Bababudan Group (Dharwar Supergroup) of the western Kamataka Craton provide a precise age for the onset of BIF deposition in the basin. Sample 120019C, from the exact base of the BIF, gave an age of 2720 ± 7 Ma, while sample 120018C, 14.5m above the base, gave an age of 2718 ± 6 Ma. The second sample contained younger grains which may have been affected by a late thermal event.

Abstract

An experiment was conducted with rice (cv. GOTRA BIDHAN - 1) in soils of Terai alluvial situation of West Bengal during the Rabi season of 2009-2010 to find out the effect of some primary (N-P-K) and micro (Zn-B) nutrients along with organic matter on the variability of yield of rice. The treatments were based on the soil-test based fertilizer recommendation . The average grain and straw yield of rice varied from 2.28 to 4.31 t ha^-1 and 3.12 to 4.67 t ha^-1, respectively. Maximum grain yield of rice was obtained at the optimum application of the given nutrients. Omission of nutrients from the optimum, caused yield losses from 9.9 to 47.1 per cent. The yield data also revealed that N-P-K-Zn and B were the main limiting factors under the present experimental set-up. The results suggested the need for applying the given nutrients at optimumlevels for the successful yield maximization programme.

Abstract

A study was conducted on the distribution of different forms of zinc (Zn) in soils (0–20 and 20–40 cm depths)in different blocks of Cooch Behar district, West Bengal,India. The soils of the selected areas were acidic in reaction (pH) at both the depths, ranging from 4.23 to 6.96 (0–20 cm) and 3.89 to 6.45 (20–40 cm) and having sandy to sandy loam texture. The different fractions of Zn varied among the soils of all locations. The order of different zinc fractions was: exchangeable zinc(Ex-Zn) < organic matter-bound zinc (OM-Zn) –1 at 0–20 cm depth and 0.92 kg ha^–1 in the soils of Tufanganj-II at 20–40 cm depth respectively. Exch-Zn,OM-Zn, Mn-Ox-Zn and Am-Ox-Zn were positively correlated with CEC (r = 0.088, r = 0.105, r = 0.137, r = 0.103) at 0–20 cm depth, while at 20–40 cm depth, Exch-Zn, OM-Zn, Mn-Ox-Zn, Am-Ox Zn and Cry-Ox-Zn were positively correlated with CEC (r = 0.204, r = 0.168, r = 0.342, r = 0.123, r = 0.278). The influence of different soil properties on the distribution of Zn fractions in the soils was apparent from this study.
