Using a panel data approach, it is found that increases in world market shares of China are statistically correlated with declines in world market shares for some Asian countries since 1994, but not before 1994.

This is seen in the decline in growth after the Asian financial crisis, by the sector's decline relative to other sectors within the economy, and relative to countries in the region. This note documents the effects of the challenging macro and external environment on the profits of manufacturing firms, and on the uncertainty they face, and argues that these adverse conditions partially explain the stagnation of the sector in the past decade. The changes in incentives appear to have particularly affected labor-intensive sectors, with important consequences for job creation. Policies to promote growth in the manufacturing sector should aim at alleviating pressures on manufacturing costs by: (i) reducing rigidities in the market for labor; (ii) promoting competition in the market for services; and (iii) providing incentives for productivityenhancing technology adoption, while reducing profit uncertainty by (iv) maintaining a low and predictable rate of inflation and (v) keeping exchange rate volatility within reasonable limits.

The aim is to draw lessons on what policies can best position these countries going forward to enjoy growth without a buildup in macro and financial vulnerability. Cluster analysis is used to classify these countries across the

The phenomenon of self healing was observed when the system was studied at a very slow rate of 0.05 ps. Cracks initiated in the graphene sheet was allowed to propagate till it reached a critical length following which the load was removed and the sheet was relaxed. The study revealed that self healing of cracks took place within a critical crack opening displacement range of 0.3–0.5 nm in absence of any external stimulus. However, the self healing phenomenon was found to be independent of crack length. This self healing phenomenon occurred not only in pristine graphene sheet, but also in presence of pre-existing vacancies. The mechanism of self healing has been explained by detailed bond length/angle distribution analysis.

Hollow cylindrical Al-6061 T6 projectiles, driven in a coilgun system, suffer radial compression ... more Hollow cylindrical Al-6061 T6 projectiles, driven in a coilgun system, suffer radial compression and buckle into quadrilateral or pentagonal cross sections. In some cases, the projectiles fail by developing longitudinal cracks in the compressed region. Simulations of the coilgun-projectile system, using Johnson-Cook and Bao-Wierzbicki failure models, reproduce buckling and formation of longitudinal cracks via localization of plastic strain and high temperatures around the bends of the buckled geometry. Failed specimens were micro-graphically investigated and the cause of failure attributed to synergistic effect of buckled geometry and localized high temperature zones.

Optimization of the fermentation conditions for chitin deacetylase (CDA) production by Penicilliu... more Optimization of the fermentation conditions for chitin deacetylase (CDA) production by Penicillium oxalicum SAE-51 was undertaken in the present study using central composite design (CCD) under submerged condition. CDA is widely employed for bio-catalytic conversion of chitin to chitosan. Chitosan is a biopolymer with immense commercial potential in diverse industrial sectors, viz. pharmaceutics, food, agriculture, water treatment, etc. CDA production was significantly affected by all the variables studied, viz. pH, temperature, inoculum age and size. The optimal conditions that stimulating maximal CDA production were found to be: pH, 7.9; temperature, 28 °C; inoculum age, 90 h, and 11 % inoculum size. Under these optimized conditions, the actual maximal CDA production was 623.57 ± 8.2 Ul, which was in good agreement with the values predicted by the quadratic model (648.24 Ul), confirming the validity of the model. Optimization of fermentation conditions through CCD had resulted into 1.4-fold enhancement in CDA productivity (Q = 4.3264 Ul h). Results of these experiments indicated that response surface methodology was proved to be a promising method for optimization of CDA production.

U bend samples of machined plate were exposed to acidified SO 4 + Cl À environment at room temperature to study its ambient temperature SCC behavior. The results correlate the SCC behavior of the SS tubes and roll expanded joints to the nature and magnitude of residual stresses present. The study also highlights the distinct difference in ambient temperature SCC behavior of machined vs. nonmachined surfaces.

However, there is limited information on prevalence and genetic diversity of human metapneumovirus (hMPV) strains circulating in India. To study prevalence and genomic diversity of hMPV strains among ARTI patients reporting in outpatient departments of hospitals in Kolkata, Eastern India. Nasal and/or throat swabs from 2309 patients during January 2006 to December 2009, were screened for the presence of hMPV by RT-PCR of nucleocapsid (N) gene. The G and F genes of representative hMPV positive samples were sequenced. 118 of 2309 (5.11%) clinical samples were positive for hMPV. The majority (≈80%) of the positive cases were detected during July-November all through the study period. Genetic analysis revealed that 77% strains belong to A2 subgroup whereas rest clustered in B1 subgroup. G sequences showed higher diversity at the nucleotide and amino acid level. In contrast, less than 10% variation was observed in F gene of representative strains of all four years. Sequence analysis also revealed changes in the position of stop codon in G protein, which resulted in variable length (217-231 aa) polypeptides. The study suggests that approximately 5% of ARTI in the region were caused by hMPV. This is the first report on the genetic variability of G and F gene of hMPV strains from India which clearly shows that the G protein of hMPV is continuously evolving. Though the study partially fulfills lacunae of information, further studies from other regions are necessary for better understanding of prevalence, epidemiology and virus evolution in Indian subcontinent.
