Study of the nickel silicates associated with the ultrabasic rocks of Nuggihalli schist belt, mysore state

The occurrence of some nickel silicate minerals as encrustations along joint planes and shear zones of the chromite bearing ultrabasic rocks of Nuggihalli schist belt is described. Chemical and X-ray study shows besides amorphous nickel silicate, the presence of granierite, nepouite or nickel antigorite. The nickel minerals are secondary developed by the action of circulating waters. The source of nickel is olivine, in the structure of which Ni is known to be present, either as camouflaged or captured ion

Communities, Knowledge, and Innovation: Indian Immigrants in the US Semiconductor Industry

This paper investigates the influence of technological, geographic, and ethnic communities on the innovativeness of Indian inventors. We study Indian inventors in the semiconductor industry in the US and examine their patenting profiles between 1975 and 1999 to identify the influences on the quantity and quality of their innovations. We find that inventors who rely on knowledge from technological and geographic communities enhance their innovativeness. Knowledge from the ethnic Indian community is related to inventor innovativeness in the form of an inverted U. The negative effect of knowledge gained from the ethnic community on innovativeness is pronounced for experienced inventors.innovation, knowledge, semiconductor industry

Subsidiary Development of New Technologies: Managing Technological Changes in Multinational and Geographic Space

This study explores the co-evolution of the subsidiaries of the multinational firm with their global organizations and geographic locations. We examine when and how subsidiaries make sense of and respond to technological changes in these environments to expand their scope and develop new technologies. Using the concept of local search, we propose that technological changes in a subsidiary’s parent firm and host country, in areas specific to the subsidiary’s expertise and at the broad industry level, have differential effects on subsidiary development of new technologies. We further propose that subsidiary innovative capability acts as a moderator, enabling subsidiaries to respond to technological changes and develop new technologies

Leveraging Knowledge Across Geographic Boundaries

This paper examines knowledge flows within and across geographic boundaries of clusters and nations in the biotechnology industry. We hypothesize that these flows are characterized by various factors relating to the knowledge itself and by firm innovativeness and the presence of prior knowledge flows at the firm level. Surprisingly, our findings suggest that geographic proximity does not matter in some instances, while in others it has a decidedly nonlinear effect opposite to that hypothesized. The pattern of findings points to the greatest contrast in the comparison of between-cluster and between-country flows and presents an opportunity to reevaluate the role of geography and knowledge flows

Wet Granular Materials

Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many industrial applications), liquid is present between the grains. This produces inter-grain cohesion and drastically modifies the mechanical properties of the granular media (e.g., the surface angle can be larger than 90 degrees). Here we present a review of the mechanical properties of wet granular media, with particular emphasis on the effect of cohesion. We also list several open problems that might motivate future studies in this exciting but mostly unexplored field.Comment: review article, accepted for publication in Advances in Physics; tex-style change

The effects of applied water at various fractions of measured evapotranspiration on reproductive growth and water productivity of Thompson Seedless grapevines

The reproductive growth and water productivity (WPb) of Thompson Seedless grapevines were measured as a function of applied water amounts at various fractions of measured grapevine ETc for a total of eight irrigation treatments. Shoots were harvested numerous times during the growing season to calculate water productivity. Berry weight was maximized at the 0.6–0.8 applied water treatments across years. As applied water amounts increased soluble solids decreased. Berry weight measured at veraison and harvest was a linear function of the mean midday leaf water potential measured between anthesis and veraison and anthesis and harvest, respectively. As applied water amounts increased up to the 0.6–0.8 irrigation treatments there was a significant linear increase in yield. Yields at greater applied water amounts either leveled off or decreased. The reduction in yield on either side of the yearly maximum was due to fewer numbers of clusters per vine. Maximum yield occurred at an ETc ranging from 550 to 700 mm. Yield per unit applied water and WPb increased as applied water decreased. The results from this study demonstrated that Thompson Seedless grapevines can be deficit irrigated, increasing water use efficiency while maximizing yields
