Time Enough - Consequences of Human Microchip Implantation

Dr. Ramesh argues that microchip implantation is both possible and, for some purposes, desirable and suggests that now is the time to consider strategies for preventing potentially grievous intrusion into personal privacy

Serological tests for syphilis may show varying results in association with HIV infection.Thus care should be taken to interpret these result

Dividend Behaviour of Indian Companies Under Monetary Policy Restrictions

In this study we examine the dividend behaviour of Indian companies. We use GMM estimator, which is the most suitable methodology in a dynamic setting. Our results show that the Indian firms have lower target ratios and higher adjustment factors. The most significant result is that the restricted monetary policies have significant influence on the dividend behaviour of Indian firms, causing about 5-6 percent reduction in the payout ratios. The significance of macro economic policy variable suggest that monetary policy restrictions do have impact on cost of raising funds, and the information asymmetry between lenders and borrowers increases that forces companies to reduce their dividend payout.

Toxicity of copper sulphate on some haematological parameters of a freshwater teleost Cyprinus carpio var. communis

Haematological changes in a freshwater teleost, Cyprinus carpio var. communis, exposed to acute and sublethal toxicity of copper sulphate were studied. During the acute treatment, erythrocyte and leucocyte count, and haemoglobin content increased, whereas during the sublethal treatment, erythrocyte count and haemoglobin content decreased and leucocyte count increased

Quantifying perception of nonlinear elastic tissue models using multidimensional scaling

Simplified soft tissue models used in surgical simulations cannot perfectly reproduce all material behaviors. In particular, many tissues exhibit the Poynting effect, which results in normal forces during shearing of tissue and is only observed in nonlinear elastic material models. In order to investigate and quantify the role of the Poynting effect on material discrimination, we performed a multidimensional scaling (MDS) study. Participants were presented with several pairs of shear and normal forces generated by a haptic device during interaction with virtual soft objects. Participants were asked to rate the similarity between the forces felt. The selection of the material parameters – and thus the magnitude of the shear\ud and normal forces – was based on a pre-study prior to the MDS experiment. It was observed that for nonlinear elastic tissue models exhibiting the Poynting effect, MDS analysis indicated that both shear and normal forces affect user perception
