Crystallographic and modelling studies on a mannose-specific lectin from garlic bulbs
Lectins are multivalent carbohydrate-binding proteins which exert their biological effects through their ability to specifically bind different sugars. They occur in plants, animals, bacteria, and viruses. They exhibit ... -
Hydration, mobility and action of proteins : an x-ray study involving hen-egg-white lysozyme and human hemoglobin
Hydration and mobility of proteins have received considerable attention. It is also recognized that the two are related. A long-range protein crystallographic program in this laboratory is concerned with protein hydration ... -
Computer modelling approach to study the mode of binding of flavins to flavodoxin
Abstract not available -
Insertion Reactions of copper (I) Aryloxides with heterocumulenes
Studies on alkoxide and aryloxide complexes of copper(I) are significant due to their relevance to biological systems and their potential in small molecule activation. In the present investigation, the insertion reaction ... -
Thermal decomposition studies on the exalate of uranium(IV), praseodymium and neodynium
Thermogravimetric Analysis: The decahydrate on heating gives rise to a monohydrate, which loses its last mole of water on further heating to give the anhydrous oxalate that is quite stable in the range 350–400°C. The oxalate ... -
Theoretical investigations on fluxionality, molecular devices and chemical binding
In the recent past, considerable attention has been focused on the design and synthesis of molecular devices [1]. Molecules that can perform various kinds of interesting motions, such as ratcheting, shuttling, harpooning, ... -
Study of electromechanical and optoelectronic behavior of carbon nanostructures
Electric field induces a large actuation (up to 14-30%) in bulk CNT cellular structure. The actuation is symmetric, polarity independent, non-instantaneous, and directly proportional to the square of the applied electric ... -
A Stochastic estimation approach to emission tomography
Emission Computed Tomography (ECT) is a medical imaging modality which is potentially useful in the study of human physiology and organ functions. In ECT, a physiologically active compound is radio-labelled and introduced ... -
Studies on improvement of acoustic bragg imagery
Acoustic Bragg Diffraction Imaging (ABI) enables non-invasive visualization of object details opaque to light. It renders real-time imaging, preserves phase information, and is simple in implementation. Even though ABI has ... -
Dependence of post-aggregative cell fate on early phenotypicdifferences with respect to cellular calcium and cell cycle phase in Dictyostelium discoideum
The social amoeba Dictyostelium discoideum is an excellent model system to study cell differentiation and embryonic development. Its life cycle consists of a unicellular phase involving feeding, growth, and multiplication, ... -
Studies on recombinant DNA expression of follicle stimulating hormone and its receptor
Follicle Stimulating Hormone (FSH), a pituitary gonadotropin, belongs to the family of glycoprotein hormones and plays a crucial role in mammalian reproduction. It is a heterodimer consisting of an -subunit noncovalently ... -
Exploration of natural and polymer based composites for advanced engineering design
Light weighting is an important requirement in design today to save energy. For example, reduction in the weight of a vehicle can lead to improved fuel economy. Concomitantly, there is a great need for choosing lightweight ... -
Conservation strategy for the birds of the uttara kannada district.
The forests of Uttara Kannada have had a long history of disturbance and transformation by humans. As they stand today, woody plant species numbers tend to fall with the declining rainfall gradient in a northeastern ... -
Ecology of the Asian Elephant (ELEPHAS MAXIMUS) and its Interaction with man in south India-Vol2
Abstract not available -
Prediction of rainfall state using a hidden state Markov model
ainfall prediction is a challenging problem because of the various uncertainties involved in rainfall processes. Nevertheless, long-term prediction of rainfall state is of great significance for the planning and management ... -
Finite element analysis of stress concentrations and singularities
Stress concentrations or singularities occur in a structure whenever there is a sharp change in geometry, or discontinuities in loading or material properties. In the analysis of problems with significant concentrations, ... -
Role of AMPK in regulating morphogenetic processes during cancer and embryonic development
Title: Role of AMPK in regulating morphogenetic processes during cancer and development Abstract: AMP-activated protein kinase (AMPK) is a central regulator of cellular energy homeostasis, integrating metabolic status ... -
Vertical structure of convective clouds using the TRMM PR data
Very small fractional area (0.1%) occupied by the cumulonimbus (Cb) clouds belies their importance in Earth's hydrological cycle and climate. For example, Riehl and Malkus (1958) estimated that the vertical transport of ... -
Outflow of continental aerosols from peninsular India to Bay of Bengal
Aerosols are complex entities to assess in the atmosphere. This complexity arises due to their high variability both spatially and temporally, because of the different types of sources at different locations and their ...
