UNRESTRAINED MEASUREMENT OF ARM MOTION BASED ON A WEARABLE WIRELESS SENSOR NETWORK

Techniques that could precisely monitor human motion are useful in applications such as rehabilitation, virtual reality, sports science, and surveillance. Most of the existing systems require wiring that restrains the natural movement. To overcome this limitation, a wearable wireless sensor network using accelerometers has been developed in this paper to determine the arm motion in the sagittal plane. The system provides unrestrained movements and improves its usability. The lightweight and compact size of the developed sensor node makes its attachment to the limb easy. Experimental results have shown that the system has good accuracy and response rate when compared with a goniometer

Role of Nanotechnology in Prosthodontics: a review

In the present-day context, a considerable portion of the population faces the challenge of edentulism. Various treatment approaches, including both fixed and removable prostheses, are available for restoring missing teeth. Noteworthy progress has recently been observed in the characteristics of commonly used dental materials, attributed to the emergence of nanotechnology. This technological advancement has significantly contributed to improving the outcomes of dental treatments. Nanotechnology represents a multidisciplinary domain that amalgamates principles from both the arts and sciences, involving the manipulation of structures and functional materials at a minuscule scale. This field leverages various physical and chemical methodologies to operate at dimensions where sizes of particles, typically ranging from 1 to 100 nanometers, give rise to what is termed as Nanoparticles. The integration of nanoparticles in dentistry, particularly within dental materials such as ceramics, acrylic resin, tissue conditioners, and denture adhesives, has exhibited a discernible positive impact on their inherent properties. This review predominantly delves into an exploration of diverse applications of nanoparticles within the realm of dentistry, with a specific emphasis on their role in prosthodontics

Prosthodontic management of subtotal maxillectomy with minimally invasive interim obturator: a case report

The interim obturator serves as a pathway between the immediate or surgical obturator and the final prosthesis, offering functional and aesthetic benefits until the delivery of the definitive prosthesis. Furthermore, it acts as a guide during the fabrication of the definitive prosthesis, influencing aspects such as prosthesis extension, teeth arrangement, and the positioning of retentive aids. These aids may encompass orthodontic wiring, surgical suturing, and other non-invasive techniques. This case report details a conservative and less invasive method for retaining an interim obturator in maxillectomy patients, providing an alternative approach in prosthodontic care

Feeding plate prosthesis for an infant with cleft lip and palate: a case report

Cleft lip and palate are congenital anomalies that manifest at birth, leading to a range of complications such as feeding challenges, dysfunction of the eustachian tube, middle ear infections and effusion, hearing loss, speech disorders, and dental and orthodontic issues. A feeding plate is a prosthetic solution crafted to address these challenges by effectively sealing the cleft and restoring the separation between the oral and nasal cavities. This case report details the procedure for fabricating a feeding plate specifically designed for neonates with cleft lip and palate

Different Omics Approaches in Cereals and Their Possible Implications for Developing a System Biology Approach to Study the Mechanism of Abiotic Stress Tolerance

Cereals comprise a number of crops including rice, wheat, maize, barley, rye and sorghum. In the form of starch and proteins, the cereal grains provide nearly 60 % of the calories consumed globally as food and fodder. There is a growing challenge to meet the global demand of food security for a human population of 9 billion expected by the year 2050

Lie Group Analysis for Boundary Layer Flow of Nanofluids near the Stagnation-Point over a Permeable Stretching Surface Embedded in a Porous Medium in the Presence of Radiation and Heat Generation/Absorption

This study investigates the influence of thermal radiation and heat generation/absorption on a two dimensional steady boundary layer flow near the stagnation-point on a permeable stretching sheet in a porous medium saturated with nanofluids. The governing partial differential equations with the appropriate boundary conditions are reduced to a set of ordinary differential equations via Lie-group analysis. The resultant equations are then solved numerically using Runge - Kutta fourth order method along with shooting technique. Two types of nanofluids, namely, copper-water and alumina-water are considered. The velocity and temperature as well as the shear stress and heat transfer rates are computed. The influence of pertinent parameters such as radiation parameter Nr, nanofluid volume fraction parameter , the ratio of free stream velocity and stretching velocity parameter a/c , the permeability parameter K1, suction/blowing parameter S, and heat source/sink parameter on the flow and heat transfer characteristics is discussed. The present study helps to understand the efficiency of heat transfer transport in nanofluids which are likely to be the smart coolants of the next generation

A FAST AND SENSITIVE SPECTROPHOTOMETRIC METHOD FOR THE DETERMINATION OF HYDRAZINE IN ATAZANAVIR SULFATE DRUG SUBSTANCE

Objective: To develop a fast and sensitive UV spectrophotometric method for the quantitative estimation of Hydrazine in Atazanavir Sulfate drug substances and validate as per ICH guidelines. Methods: The method was based upon the observation, that a characteristic colour results upon addition of a solution of p-Dimethylaminobenzaldehyde in ethyl alcohol and hydrochloric acid to hydrazine and estimated at absorbance maximum  458 nm in Atazanavir drug substance. Results: The developed method resulted in Hydrazine exhibiting linearity in the range 0.2 to 2.7 µg/g. The Intraday and interday precision is exemplified by relative standard deviation of 0.959 % and 0.947%. Percentage Mean recovery was found to be in the range of 97â€101%, during accuracy studies. The limit of detection (LOD) and limit of quantitiation (LOQ) were found to be 0.2 µg/g and 0.6 µg/g respectively. Conclusion: The present work was aimed to develop a visible spectrophotometric method, which is simple, sensitive, accurate and cost effective to evaluate the quality of the bulk and pharmaceutical formulations

Chemical Reaction Effects on an Unsteady MHD Mixed Convective and Radiative Boundary Layer Flow over a Circular Cylinder

A mathematical model is presented for an optically dense fluid past an isothermal circular cylinder with chemical reaction taking place in it. A constant, static, magnetic field is applied transverse to the cylinder surface. The cylinder surface is maintained at a constant temperature. New variables are introduced to transform the complex geometry into a simple shape and the boundary layer conservation equations, which are parabolic in nature, are normalized into non-similar form and then solved numerically with the well-tested, efficient, implicit, Crank-Nicolson finite difference scheme. Numerical computations are made and the effects of the various material parameters on the velocity, temperature and concentration as well as the surface skin friction and surface heat and mass transfer rates are illustrated graphs and tables. Increasing magnetohydrodynamic body force parameter (M) is found to decelerate the flow but enhance temperatures. Thermal radiation is seen to reduce both velocity and temperature in the boundary layer. Local Nusselt number is also found to be enhanced with increasing radiation parameter
