Incidence of ambergris washed ashore

Ambergris is a valuable substance obtained from Sperm whale. It is either found floating in the sea or obtained by cutting open theanimal. It is produced in the intestine and retained mostly in the colon. Ambergris is a solid inflamable waxy substance

Hindu-Christian Dialogue: A Hindu Perspective

I wish to express my deep appreciation and thanks to Professor Harold Coward for inviting me to contribute an article on Hindu-Christian Dialogue: A Hindu Perspective for his Bulletin. This theme has engaged my interest for the last three decades, and I am glad at the opportunity to express my thoughts on this very relevant and significant subject at the dawn of the 21st century

Improved controller design for two-input-two-output (TITO) unstable processes

Controller design for unstable processes is relatively difficult when compared to stable processes. The complexity increases further for multivariable unstable processes. In this work, simplified tuning rules are proposed to design PID controller for unstable multivariable processes. Decouplers are applied to make the loops independent and diagonal elements of equivalent transfer function are used to design controllers. For this, the decoupler design procedure proposed by Hazarika and Chidambaram [10] is used. Two theoretical examples of TITO unstable processes with time delays are considered for simulation. Comparative analysis has been carried out with the recently reported methods in the literature and observed that the proposed method provides improved closed loop performances. Robustness studies are also carried out with various perturbations in the processes

Crafts and gear used for marine fishing along the Andhra Pradesh coast

Until the middle of nineteen sixties fishing for marine finfishes and shellfishes along the Andhra Pradesh coast used to be carried out employing indigenous non-mechanised crafts. Subsequently trawlers and later mechanised vessels operating gillnets came into use which resulted in the increased fish production. Use of outboard engine on indigenous crafts for reaching fishing grounds is a recent feature of near the coast fishing. The different kinds of non-mechanised and mechanised crafts and gear employed in the region are dealt with in this article

Major and minor fisheries harbours of India. 7. The fisheries harbours and fishery along the north Tamilnadu and south Andhra Pradesh coasts

There are four functional fisheries harbours in the north Tamil Nadu-south Andhra Pradesh coast, viz., Chennai (major), Nizampatnam, Cuddalore and Pazhayar (minor). A medium harbour in Pondicherry is under construction. There is a temporary jetty in Krishnapatnam and a fish landing platform in Pulicat

Effect of Tris and Biociphos-Plus Extenders on the Extracellular Enzyme Release of Phosphatases and Transferases in Punganur Bull Semen

The present investigation was carried out to study phosphatase and transferase enzymes leakage in the neat and extended Punganur bull semen before and after freezing with Tris and Biociphos-plus extenders. Among the bulls studied, the Alkaline Phosphatase (AKP) concentration in fresh semen was significantly different but Acid Phosphatase (ACP) was not significantly different and a positive correlation between the concentration of AKP and semen volume, individual motility, sperm concentration and total abnormalities were observed. Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) concentrations were not significantly different and positively correlated with individual motility, sperm concentration, percentage of live sperms and acrosomal damage. Leakage of AKP, ACP, AST and ALT enzymes before freezing the semen of Punganur bulls was observed to be significantly higher in the semen extended with Biociphos-plus extender
