Understanding Metabolic Syndrome and its Nutritional Management
Abstract: Metabolic syndrome (MetS) is a collection of risk factors, especially when at least three occur together, including abdominal obesity, dyslipidemia, low high-density lipoprotein cholesterol (HDL-c) levels, hypertension, and insulin resistance. MetS is linked to an increased risk of diabetes and cardiovascular diseases (CVDs) if treatment is not received.The causes of MetS include both genetic and acquired factors that contribute to issues such as insulin resistance, chronic low-grade inflammation, and obesity. …

The Characteristics of Square-Well Fluid Transport Coefficients
Abstract: The transport coefficients of the hard-sphere system were first computed by Alder, providing foundational insight into the microscopic origins of viscosity, diffusion, and thermal conductivity in simple fluids. Building on this framework, Evans derived a generalized Langevin equation to describe the time evolution of dynamical variables, incorporating memory effects and non-Markovian behavior in molecular motion. These theoretical developments established a bridge between microscopic interactions and macroscopic transport properties. When an …

Design and Implementation of IoT-enabled Movable Road Divider for Vehicular Traffic Control
Abstract: Road dividers are widely used to separate continuous and incoming traffic on road. This is useful for maintaining traffic flow. In this case, there are equal numbers of lanes for incoming and continuous traffic. However, in specific zones, such as industrial or shopping zones, traffic generally flows in one direction in the early morning or late at night. There is nothing or no use on the other side of the …

Cluster Based Sleep Transistor Approach for Low Power 6T SRAM Cell
Abstract: The demand of high density VLSI circuits has been increasing as the size of ICs is becoming small day by day. It has been seen that, to reduce active power dissipation in memory, the supply voltage reduction is necessary. Lowering the supply voltage is one of the most straightforward and effective ways to suppress the energy consumption because reducing the supply voltage could reduce the dynamic power and leakage power …
