Published: December 2020

Abstract
Medical implants are devices, tissues or supports that are positioned in a suitable manner on any defective part of the human body to facilitate its smooth functioning again. Known as ‘prosthetics’, they may be used to offer support to a specific organ or tissues, distribute medication, or observe the body condition. While many of the implants are made from skin, bone or other tissues removed from the body itself, the artificial ones are made from engineering materials which could be any of the compatible metals, plastics, ceramics or even composites. The high end technologically advanced implant material is expected to withstand severe barriers and compatibility issues when in contact with the human body. One such application is dental implants, where, the materials must possess superior mechanical properties, exhibit good hydro-chemical and low thermal degradation characteristics. They are also required to possess characteristics such as low friction, strong wear resistance, good wettability and biocompatibility, when placed in the mouth. The only materials that come close to meeting the needs are ceramics, limited by the associated high fracture rate. Stabilized zirconia (stabilized with yttria, ceria etc.) has provided potential solution. Among the two stabilizers, ceria stabilized zirconia may be a better alternative to yttria stabilized zirconia. Other alternatives are alumina, apatites: but their use are constrained based upon technological and cost considerations. Implant product is a highly demanding technology. Spray drying is a suitable process methodology to obtain free flowing powders with uniform morphology and chemical composition, essential for an implant production. This paper presents (i) results from spray drying 8% Y2O3-stabilized ZrO2 and (ii) a review of published literature pertaining to dental implant materials, the various processing methodologies, with special reference to stabilized zirconia and spray drying.

Abstract
In an expansive environment, due to continuous change of location of objects, tracking a moving object is a challenging task, in intelligent IoT service provisioned. Tracking of objects indoors using conventional methods like GPS can give out signals not as accurately as we get outside due to the signal attenuation, thus GPS gets poor results, moreover, the inclusion of other effective positioning modules increases the overall cost of production of the device. Nowadays, Wi-Fi networks are prevalent in most public buildings and do not require any additional infrastructure, so we have come with an idea of this is that we could propose an efficient and reliable Wi-Fi-real time tracking system with help access points and signals strength. We are using a combination of two approaches where the first one uses pre-recorded received signal strengths. From the access points, and data is transmitted from the user on the move. It is known as the fingerprinting method. The second approach is trilateration from the known access points coordinates from the user’s device to find the position. The combination of these steps improves the accuracy of the user position in an indoor environment. The experiments presented in this research helps us understand and provide the source of a foundation for the indoor/outdoor positioning.

Abstract
In this study, the investigation on thermal property and characteristic analysis of Poly Ethylene Glycol (PEGs) material by varying the molecular weights is examined. In this context, the study on thermal energy material storage is explored by using the different techniques such as Differential Scanning Calorimetry (DSC) for persistent heating rate and Thermal Gravity Analysis (TGA) for determining the amount of change of mass of the material in addition to the function of increasing temperature. Subsequently, the characterization of PEGs with different molecular weight is carried out to explore the property and insight of the material by using the Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) by examining the surface topology, crystallography in addition to this the X-Ray Diffraction (XRD) techniques for catch a glimpse of the crystal structure is studied. As an outcome, in the DSC techniques the results made known when the molecular weight increases, correspondingly the melting temperature and solidification temperature similarly increases however, the heat of fusion during the freezing cycle increases. In the TGA techniques, similarly specified increases in the volume of PEG with different molecular weight has resulted in an increase in the temperature. Subsequently, in the characterization of the PEGs, the SEM has shown an enormous amount of insignificant sphere-shaped crystal-like structures which are joined together and impinging on their neighbour’s which paved the way for the formation of a multi-layered lamellar structure in due course activated rise in the solidification temperature in its molecular weight. Henceforth, from the analytical studies, it’s been evident that the molecular weight greatly influences the mechanical and thermal properties of PEGs. In this concern, the PEGs blends are a potential benefit to replace pure components.

AbstractComposite materials are highly suitable to withstand with mechanical loads compared to conventional materials. At present, these materials are being substituted with composite materials due to their superior properties and broadly used in aerospace industries and other industries. In this work, investigations are conducted out to determine the mechanical properties of composite laminates, for various orientations (0°/30°/45°/60°) of kevlar fibres with glass fibres. The different mechanical testing such as tensile test, flexural test and dynamic Mechanical Properties of the hybrid composite material with various orientations of the top and bottom Kevlar laminates were evaluated. It is concluded that the Fabricated hybrid composites with 0° orientation of the Kevlar fibres exhibit higher tensile Strength as well as flexural strength compared to the composites with oriented kevlar fibres (30°/45°/60°). The increased mechanical properties of the 0° hybrid is due the alignment of the kevlar fibres in loading direction which causes it to act as the primary load bearing structure whereas in the oriented hybrid composites the glass fibre acts as the initial load bearing structure.

Abstract
The objective of the article is to study the performance of domestic refrigerator with waste heat recovery system. The usage of domestic refrigeration systems are increasing every day due to the requirement. During the operation of domestic refrigeration system, heat is rejected through the condensing coil to the atmosphere and leads to thermal pollution. Hence this heat can be recovered by suitable waste heat recovery system and employed for useful domestic applications. Hot chamber box has been fabricated and assembled with the domestic refrigerator. Experimental analysis has been carried out under air cooled condenser and hot chamber condenser with different loading conditions like no load, 1 litre, 3 litres, 5 litres, and 10 litres of water in the evaporator unit. COP is calculated for all the loading conditions and compared with air cooled condenser and hot chamber condenser. COP of all the loading conditions is maintained almost in the same range value. COP value is obtained in the range of 5 to 5.5 for the air cooled and hot chamber condensation modes. Hence the performance of domestic refrigerator is not changed due to the running of hot chamber box. Due to installation of hot chamber box waste heat is recovered from the condenser coil. The maximum heat recovery is arrived in the range of 31.15 to 33.66 kJ/kg.

Published: December 2020

Abstract
Silver nano colloids are prepared using Tea leaf as reducing and stabilizing agent. Samples with different concentrations of the reducing agents are irradiated with gamma rays of various doses. Transmission Electron Microscope images of the samples show agglomerated clusters of nano particles before irradiation while the images of after irradiation show chain free individual nano particles with reduced size and spherical morphology. The Selected Area Electron Diffraction pattern confirms the crystal nature and face centred cubic structure of nano silver. UV-Visible spectroscopy gives absorption peaks in the blue region. Gamma irradiation results in the reduction in peak intensity without any change in wavelength. A statistical approach is done on treating the gamma irradiated colloidal sample with the as prepared silver nano colloid for measuring the affected area of fungal infection on a potato-agar medium. It is found that the fungal growth is declined rapidly with the introduction of gamma irradiated silver nano colloid than the as prepared colloid.

Authors: Limmun W , Chungcharoen T 
Published: December 2020

Abstract
The hulling process for coffee bean extraction may not effectively release the bean from parchment. This might negatively affect the aroma or taste of coffee in the coffee beans roasting process. Consequently, the objectives of this work were to design and construct a machine for separating parchment coffee from Robusta green coffee bean using a pneumatic separation system combined with sieve vibration. The performance of the separation machine was investigated under different operating conditions such as air velocity, vibration frequency, and the angle of sieve inclination. The samples were fed into the machine at a feed rate of 20 kg/h. The testing conditions were set at air velocities of 2 to 4 m/s, vibration frequencies of 36 to 40 Hz, and sieve inclination angle of 4° to 8°. The results showed that the purity and separation efficiency of parchment increased with increasing air velocity. Conversely, decreasing vibration frequency and sieve angle increased the purity and separation efficiency. The appropriate conditions for parchment coffee separation from Robusta green coffee bean using a pneumatic-sieve vibration system were 4 m/s air velocity, 36 Hz vibration frequency, and 8° sieve angle with the highest overall effectiveness of 92%.
