The group contribution method 'UNIFAC-VISCO' has become popular because of its reliable predictions of dynamic & kinematic viscosities, but suffering from a serious drawback for non-availability of sufficient group interaction parameters. A new approximate technique has been proposed in this study, in which the so called UNIFAC-VLE parameters can be used instead of the original UNIFAC-VISCO parameters. This technique was tested for 28 binary liquid systems of different categories & the values of overall AAD (%) for 7 classes of organic binary liquid systems were found to be below 6.1%. These include alcohols, alkanes, aromatics, ester, cyclic ether, as well as acetonitrile & sulfolane which are yet to be done. Predictions were carried out based on four different considerations: (a) original parameters, (b) UNIFAC-VLE parameters, (c) by considering, or (d) ignoring temperature effects on group interaction parameters. As the UNIFAC-VLE parameters are easily available & applicable for a broad range of organic compounds, its use in place of original model parameters would generalize the UNIFAC-VISCO model for predicting dynamic & kinematic viscosities.

Psychological stress has extreme adverse consequences on health. However, the molecular mechanisms that mediate and accelerate the process of aging due to stress hormone are not well defined. This review has focused on diverse molecular paths that come out in response to chronic psychological stress via releasing of excessive glucocorticoids (GCs), involved in the aging process. GCs suppress transcription of nuclear cell adhesion molecules which impair synaptic plasticity, memory formation, and cognitive ability. Again, GCs promote muscle atrophy by means of motivating ubiquitin proteasome system and can repress muscle protein synthesis by inhibition of PI3-kinase/Akt pathway. GCs also inhibit interleukin-2 synthesis through suppressing T cell receptor signal that leads to loss of T cell activation, proliferation, and B-cell activation. Moreover, GCs increase the expression of collagenase-3, RANK ligand, and colony stimulating factor-1 that induce bone resorption. In general, stress-induced GCs can play causal role for aging and age-related disorders.

Poultry farming is an emerging industry in world. But now a day it faces many problems. Mycoplasmosis is one of them. It causes a significant thrashing to the poultry industry. By studying this book researchers will easily known about mycoplasmosis problem in broiler farming. The efficacy of tylosin tartrate and tiamulin hydrogen fumarate against mycoplasmosis and their effects on body weight gain of the treated broiler is discussed in this book. This book will also help to researchers who work on pharmacological field.

The contents of this book are derived from a PhD work. This book will be benefit the students and researchers who are involved in ruminant nutrition research especially in developing countries where low quality forages are a major part of ruminant diets. The first chapter of this book details factors that limit forage digestion, methods that can improve forage quality and supplements including herbs and spices that can enhance microbial activity to increase forage utilisation by ruminants. The 2nd chapter describes the laboratory methods that can be used to determine chemical composition and their application to characterise selected forages, spices and legumes for their nutritional as well as supplementary value for ruminant feeding. The 3rd and 4th chapter present data on the in vitro forage degradability and fermentation profiles in response to different experimental treatments. Finally, the last chapter presents summary and conclusions which may help develop strategies for the use of spices as supplements for ruminants.

Consumer preference for food is motivated by many criteria and especially by its flavor. Plain dahi has a weak but distinctive and fragile flavor that is influenced by different factors, for example, viscosity, nonvolatile components, and aroma. Now there has been a good demand for fruits dahi. Traditionally, fruit like strawberry, jackfruit, apricot and black current are used for manufacture of fruit yoghurt. Recently very few research have been carried out on fruits dahi. When fruits juice is added in milk for the preparation of dahi, the taste, flavor and nutrient content of dahi is increased. Among different types of fruit, mango is customary fruit and the price of mango is cheaper than other fruits. Researcher and students of dairy chemistry will be benefited by studying this book and will know the details of manufacture of different types of dahi, determination procedure of nutritive value of milk, dahi and mango juice. Manufacturer will be able to produce mango fruit dahi using appropriate level of mango.

The contents of this book are derived from a Masters work. This book will benefit the students, farmers and researchers who are involved in poultry nutrition. The book details aflatoxin in poultry feed and nutrient availability and requirement in poultry feed in Bangladesh in different seasons. The book will give information on different sources of feed and feeding practices followed by the poultry farms.

The purpose of this research was to find out the nature of health hazards caused by river erosion and analysis patterns of economic and social adaptation among river-bank erosion-induced displaces in Dacope Upazila under Khulna District of Bangladesh.The need to integrate hazard analysis and mitigation with the broader economic and social context is discussed.It is argued that the capacity of people to respond to environmental threats is a function of not only the physical forces which affect them, but also of underlying economic and social relationships which increase human vulnerability to risk.People are very vulnerable in the study area owing to river erosion.In the study area, nearly every one of the respondents (91.67%) were ill health the greater part of the people (65.8%)collected drinking water from the ponds. large amount (79.2%) were victim of Diarrhea and Dysentery, half of the population (39.2%)were Illiterate (30.8%) were involved in daily labour, (46.67%) possessed income range between BDT 1001 to 2000.So time has come, a new era has begun, we have to address problems, faced by the victims of river erosion and have to take proper initiatives for their developm

It was a field and lab based research. During this research, 16 genotypes of brinjal collected from different parts of Bangladesh. In the field level, these genotypes were cultivated and coefficient of variation and correlation coefficient were determined. The phenotypic coefficient of variation was higher than genotypic coefficient of variation in most characters.Correlation coefficient was determined to find out the interrelationship among the different characters. Fruit yield per plant was positively and significantly correlated with plant height, number of branches per plant, number of fruits per plant, number of inflorescence per plant, fruit breadth and individual fruit weight. On the other hand negative correlation was observed with flowering time and fruit length. In the laboratory research, leaf sample of the genotypes was used for isozyme analysis. The electrophoresis of the proteins of leaves was carried out using Polyacrylamide Gel Electrophoresis (PAGE) technique and the gels were stained with Peroxidase (POD), Glutamate Oxaloacetate Transaminase (GOT) and Malate Dehydrogenase (MDH) isozyme and zymogram analysis was performed.

Air-breathing fishes have become of great interest in recent years for several reasons in different countries over the world. These include the many adaptations of their respiratory and cardiovascular systems for obtaining oxygen from air and water, adaptation in their food and feeding habits, reproduction and behavior. Also, they are important source of animal protein especially in drought and flood prone areas. At present, air-breathing fishes are gradually introducing in different aquaculture practices like cage culture, waste fed aquaculture etc. Unfortunately, there is no systematic record of air-breathing fishes in Bangladesh. Species profile of air-breathing fishes with special emphasis on their air-breathing organs are described in this document. So, we strongly believe that this document would be helpful to many scientists, students and teaching staff in Bangladesh and other countries.
