Investigation of Thermo-Acoustic Properties of Ethanol-Cyclohexane Binary Mixture
Abstract: The density, viscosity, and speed of sound for ethanol-cyclohexane binary mixtures were determined across mole fractions ranging from 0.1 to 0.9 using an Anton Paar DSA 5000 M within the temperature span of 288.15–318.15 K. From these experimental measurements, several thermodynamic and acoustic properties, such as isentropic compressibility, relative association, free volume, relaxation time, Gibbs free energy of activation, internal pressure, and solubility parameter, were derived. These parameters serve as …

Article on Density Functional Theory Simulation: A Review
Abstract: Density Functional Theory (DFT) is a powerful computational approach in quantum mechanics, widely utilized for studying the electronic structure of atoms, molecules, and solids. It treats electron density as the central quantity, bypassing the complexities of solving the Schrödinger equation for individual electrons. The Hohenberg-Kohn theorem establishes that a system's ground-state energy uniquely depends on its electron density, facilitating a focus on this fundamental property. In DFT, the total energy …

An Investigation into the Impact of Progressive Muscle Relaxation on Anxiety Levels Among Nursing Students at a Selected Nursing College in Haryana, India
Abstract: Background: Nursing students often encounter significant anxiety throughout their educational journey. Key factors include heavy academic workloads, unclear assignments, and demanding shift schedules, personal and professional anxiety. Beyond these academic pressures, relationships with faculty, clinical experiences, and time constraints can also contribute to their anxiety levels. This anxiety can adversely impact student's performance if not managed effectively. Progressive Muscle Relaxation (PMR) is a well-regarded technique for alleviating anxiety, as it …

Molecular Study of Indian Herbals at Microwave Region Using Time-domain Spectroscopy
Abstract: The dielectric properties of liquids are useful to some extent to understand the liquid structure and molecular interactions therein. The study of dielectric properties of liquid materials is necessary not only to understand the liquid structure but also to provide technical data for practical uses in industry, science, medicine, and engineering. Time-domain spectroscopy (TDS), a spectroscopicmethod used in physics uses brief terahertz radiation pulses to examine the characteristics of matter. …

The Study of Urban Commercial Streets
Abstract: Street plays an important role in a city. It has diverse activities and gives a character to the whole city. Even in recent times, streets are an important and major part representing the identity of cities which also shape as public open space in the city. People hang on these streets for functional, social, and leisure activities, for playing, meeting, communication with other people; and sometimes for relaxation making it …

An Exploratory Study to Assess the Level of Blood Pressure, Associated Physical Manifestations and Risk Factors among Bank managers working in selected banks of district mohali, punjab with a view to develop informational booklet.
Abstract: Introduction: Hypertension is also known as silent killer since it has no initial symptoms but can be led to long term disease and complication. Hypertension or high blood pressure is a chronic cardiac medical condition in which the systemic arterial blood pressure is elevated. Blood pressure involves two measurements, systolic pressure (asthe heart beats) over diastolic pressure (as the heart relaxes between beats). Normal blood pressure is at or below …

An Interventional Study to Assess the Effect of Back Care on Quality of Sleep among Geriatric People of Nadiad City
Abstract: Introduction: Sleep is a condition of body and mind that recurs for several hours every night in which the sympathetic and parasympathetic system is relatively inactive, that eyes closed, the postural muscles relaxed, and consciousness practically sling. Back care was formed in 1968 as national back pain association. Back care is registered charity that aims to reduce encumbrance of back pain by providing information and support. Encouraging best practises and …
