Alternate Fates of tRNAs in Initiation and Elongation
Protein synthesis in all organisms utilizes a special tRNA called the initiator tRNA. Initiator tRNAs take part in the initiation step of protein synthesis by their direct binding to the P‐site of the ribosome. The other ... -
Bioremediation of Lead from Aqueous Solutions using Pseudomonas Species - Mechanisms & Biosensor Applications
Industrialization, urbanization and technological developments have improved the standard of living for humans on the one hand, but they also have resulted in the generation of wastes containing toxic heavy metals that are ... -
(p)ppGpp and c-di-GMP : A Tale of Two Second Messengers in Mycobacterium smegmatis
Nucleotide based second messengers are known to regulate wide variety of processes in all domains of life. Two such bacterial second messengers are (p)ppGpp (guanosine tetra- or pentaphosphate) and c-di-GMP (cyclic dimeric ... -
Solid State NMR- Development of Methods and Applications to the Study of Materials
In this chapter the application of solid state NMR techniques for the investigation of biodegradable polymers which have wide range of applications in various fields have been presented. Among many polymer systems poly ... -
Design, Synthesis and Properties of Novel Oligo-Phenylenevinylene based Supramolecular Photochromic Gels and Soft Composites with Nanomaterials
The thesis entitled “Design, Synthesis and Properties of Novel Oligo-Phenylenevinylene based Supramolecular Photochromic Gels and Soft Composites with Nanomaterials” deals with soft materials derived from low molecular ... -
Genetics of Drosophila Indirect Flight Muscles : Unraveling the Roles of Genes Involved in Muscle Development and Function
Myofibrillogenesis is a complex process involving assembly of many structural proteins in an orchestrated spatio-temporal manner to form a highly ordered contractile sarcomeric unit. Mutations in the proteins involved in ... -
Simulations of Aerosol Species over the Indian Region: Evaluation and Improvements
Increasing aerosol loading over the south Asian region, holds a potential of, perturbing the south Asian monsoon system and the Himalayan glacial coverage, and thus affecting lives of (1/4)th of the world’s population. ... -
Negotiator Initiated Connectivity Restoration in Partitioned Wireless Sensor Networks
Wireless Sensor Networks (WSN) are groups of sensors, connected by communication links, spread over the area of interest, to perform a specific task. The network may get partitioned into clusters due to unanticipated ... -
Study and Design of Energy Efficient Block Cipher for Wireless Body Area Networks (WBANs)
With the advent of better health care and medical technology, as well as miniaturized devices with built-in radios, today we can see (WBANs) emerging as one of the main research topics. The sensor nodes worn by patients ... -
Performance Analysis of Space Shift Keying in Cooperative Relaying Systems
Spatial modulation (SM) is a relatively new and attractive modulation technique for multi-antenna wireless systems. In SM, only one among ns = 2m available transmit antennas, chosen on the basis of m information bits, is ... -
Dilation Theory of Contractions and Nevanlinna-Pick Interpolation Problem
In this article, we give two different proofs of the existence of the minimal isometric dilation of a single contraction. Then using the existence of a unitary dilation of a contraction, we prove the `von Neumann's ... -
Blade Flutter in a Linear Cascade: Unsteady Loads and Flow Features in Subsonic and Transonic Flows
Vibration related issues like flutter can significantly limit the performance of aircraft engines and cause unwarranted cost and time overruns. The increased demand for more powerful yet compact engines has resulted in the ... -
Towards Design and Development of Indigenous Rate-Grade MEMS Gyroscopes
Gyroscopes sense angular speed of the body on which they are mounted. Traditional mechanical gyroscopes are big, bulky, expensive, and hence limited to a few applications. With the advent of Micro-Electro-Mechanical Systems ... -
Spatial and Coevolutionary Dynamics of Cooperation
Cooperation is ubiquitous across taxa in the animal kingdom. For example, microbes cooperate in producing antibiotic-resistant biofilms, mammals and birds collectively mob predators, and humans cooperate in utilization of ... -
Effect of Rainfall and River Discharge on the North Indian Ocean
In the north Indian Ocean, the Bay of Bengal (BoB or bay) and the Eastern Arabian Sea (EAS) receive a huge amount of rainfall during summer. Several rivers along their boundaries discharge enormous amounts of freshwater ... -

The thesis entitled “-Keto phosphonates from tartaric acid in the total synthesis of ()-4-epi-gabosine A, ()-dihydrokawain-5-ol, ()-bengamide E and Identification of MPK-09: A small molecule that restores the wild type ... -
Homogeneous Operators and Some Irreducible Representations of the Mobius Group
In this report, after recalling the definition of the M¨obius group, we define homogeneous operators, that is, operators T with the property '(T) is unitarily equivalent to T for all ' in the M¨obius group and prove some ... -
Electrocatalytic Oxidation of Organic Molecules on Nanostructured Metals on PEDOT Surface
Availability of appropriate forms of energy is one of the basic needs of the society. The demand for worldwide energy has been increasing, while the conventional energy sources have been depleting fast. As the present main ... -
Studies into Embodied and Operational Energy in Traditional and Conventional Residential Buildings in India
The role of the built environment and the construction industry in sustainable development gained global attention due to their significant share in global warming, GHG emissions, energy demand and depletion of non-renewable ... -
On Trait Evolution in a Heterogeneous Environment: Oviposition Site Selection in a Mosquito in Response to Multiple Risk Factors
A focus in evolutionary biology is to understand the drivers of diversity in animal behavioural traits in the living world. Animals facing similar problems in the environment, such as the problem of how much to invest in ...
