Bacterial cell division is regulated by the bacterial cytoskeletal protein FtsZ/MreB/RodZ and the level of Z ring assembly. MreB actin protein is found to regulate the cell wall component peptidoglycan synthesis and insertion. The cytokinesis process also is regulated during the biofilm stage at nutrient limiting conditions. However, if the nutrients are available during normal growth of life, the cell division rates and cytokinesis will be faster to reach to the optimum density to exhibit th...

IoT is the main enabling factor of the promising future communication networks. Several identification and tracking technologies, wireless sensor and actuator networks, distributed intelligence and other enhanced communication techniques are put together to establish IoT framework. Communication protocols and routing strategies in these mesh-like sensor networks should be carefully designed to cope up with the fast changing nature of the topology. This paper tries to propose a protocol in the...

Molecular compounds involving organometallic scaffolds like metallocenes and half-sandwich moieties with varied functionalities have been synthesized for their application as chemo-sensors, molecular recognition, multichannel receptor, protein binding studies, imaging agent and biosensor molecules etc. 1. Over the years, organometallic frameworks have shown unique properties of induced switching using external stimuli which led to the development of high sensitive fluorescence based mol...

Vibration control of structures subjected to wind and seismic forces has been widely studied. However, the focus on vibration control of structures against underground blasts is restricted. The ground motion caused by the blast is modelled in this study by an exponentially decaying function illustrative of an ordinary rock impact. The impact of the different parameters on execution is analyzed in the time domain by considering a sensible five-story example building using FORTRAN, Origin, ...

Foreign aid is considered as an important instrument of the foreign policy of states. It acts as a major source of foreign exchange earnings for developing countries. Therefore, it is regarded as a basic pillar of developmental process. We examine the trends and composition of foreign aid inflows in India and Sri Lanka

Spectrum sensing is one of the fundamental objective of cognitive radio network (CRN). In last one-decade the eigenvalue-based blind spectrum sensing methods have been extensively studied for CR applications. Eigenvalue-based techniques require large data sample for accurate detection of the signal under the low Signal-to-Noise ratio. This results in delayed sensing under large data sample. Thus, the recent trend is to explore the eigenvalue-detection methods under the low sample envi...

The demand for new chemicals spanning the fields of healthcare to materials combined with the pressure to produce these substances in an environmentally benign fashion pose great challenges to the synthetic chemical community. The maximization of synthetic efficiency by the conversion of simple building blocks into complex targets remains a fundamental goal. In this context, ruthenium complexes catalyse a number of non-metathesis conversions and allow the rapid assembly of complex molecul...

Globalization of semiconductor design and manufacturing has led to several hardware security issues. The problem of Hardware Trojans (HT) is one such security issue discussed widely in industry and academia. Adversary design engineer can insert the HT to leak confidential data, cause a denial of service attack or any other intention specific to the design. HT in cryptographic modules and processors are widely discussed. HT in Multi-Processor System on Chips n(MPSoC) are also catastrophic, as...

The increased testability and observability due to test structures make chips vulnerable to side channel attacks. The intention of side channel attack are leaking secret keys used in cryptographic cores and getting access to trade related sensitive information stored in chips. Several countermeasures against test based side-channel attacks are available in research literature. One such countermeasure scheme is password based access protection to IEEE 1500 test wrapper, such that only an authe...

The failure of Total hip replacement (THR) is due to the improper material selection and dimension of THR components. A dynamic analysis is carried out for two different bearings, i.e., metal/polyethylene and ceramic/ceramic bearing of three different head sizes 28,30 and 32mm respectively. The material and head sizes are optimized by the minimum stress generated in the THR assembly. The design and assembly of THR are carried out in CATIA; analysis is performed in ANSYS. A human load of 100Kg...

Strain measurement is a key element of material testing. Various contact based units exist to estimate strain viz.strain gauge, extensometer, seismic waves, acoustic emission technique etc. However, these methods have drawbacks like sensitivity issue, susceptible to external noise, vulnerable to breakage, etc. As a practical and effective tool for in-plane deformation measurement, Digital Image Correlation (DIC) technique, a non-contact based method has gain popularity and commonly being used...

Photonic waveguides have emerged as an ideal system for the study of quantum optical effects. In addition, they find interesting applications in quantum information science. I will describe my work on the transport and quantum walk of light in optical waveguides.

The in-rush current due to wake-up of power gating (PG) components causes faster discharge of battery. This work introduces an instruction controlled hybrid battery-supercapacitor (B-SC) system for longer battery life in systems with instruction controlled PG. Two instructions have been introduced along with architectural support. The first instruction disconnects the battery from the PG components if the charge in the supercapacitor greater than or equal to the charge required by wake-up of...

Seasonal labour migration is a complex phenomenon, which involves long working hours, poor living and working conditions, social isolation and poor accessibility to basic amenities. Most of the migration goes undocumented, and the lack of regulation compounds vulnerability. This exploratory study aimed to examine various social networks which promote seasonal migration every year from the districts. It also explored the working and living conditions of migrant workers at the destination and t...

The basic unit of society is family. There is a change in the structure and function of the family along with many other institutions of society. The factors like improvement in education, modern occupations, income disparities and spatial distance are affecting the solidarity of the family and its relationships. The social and economic changes have brought about a significant transformation in the traditional pattern of two-parent families in the past few decades. The single parent families ...

This paper deals with the development of an efficient Fuzzy Inference System (FIS) based architecture for mobile robot navigation. While developing the system architecture, kinematic constraints have been considered for a differential drive mobile robot. During the analysis, robot chassis is considered as a rigid body and the position of the mobile robot is represented as a point in XY- plane. The developed kinematic models are useful to find out the robot’s velocities (X-direction, Y-directi...

Globally, suicide is the second largest cause of death among 15-29 year olds (WHO, 2016). For every suicide, there are many more people who attempt suicide. Despite the exponential rise in risk taking behavior among the teens of India, adolescent mental health is a neglected issue (Kanikar & Bansal, 2015). Suicides can be prevented if we identify the risk factors associated with it. With this objective, a prospective observational study design was followed to understand the risk factors leadi...

This paper investigates the effect of width of the specimen and crack length on the fracture properties of glass/epoxy laminated composites. Three different widths namely 30, 40 and 50 mm were considered. The gauge length of the specimen was taken in such a way that it was four times the width of the specimen, and five different crack length to width ratios (a/D) were taken into consideration namely 0, 1/8, 2/8, 3/8, 4/8. The tensile test was conducted in INSTRON 8862 universal tensile machin...
