Successfully designed narrow beam geometry in Geant4 code for low energy electromagnetic interaction study. We found the errors within 0.001% in the determined results of mass attenuation coefficient and showed Geant4 isa powerful toolkit for measurement of radiation interaction parameter with matter. The variation in effective atomic number and effective electron density with incident photon energy were observed due to the prevalence of photon interaction processes. The Monte-Carlo simulations and theoretical simulation results have been showed that the polymers have good shielding properties as compared with saturated and unsaturated fatty acids. From obtained results, it was noticed that Geant4 Monte-Carlois in good accord XCOM database.

Abstract
The semiconductor industry and Microelectronics based devices are in urgent need of materials having low dielectric constant (κ). Efforts are being made, world over, to develop low dielectric (say κ < 2.0) materials for microelectronic applications It is thus of interest to develop materials having low dielectric constant (κ). Polyimide is widely used as packaging material in microelectronic devices packaging due to its good thermal and mechanical properties and good adhesion to metal surfaces. However, the dielectric constant of normal PI is high (κ ∼3.4) as per the requirement of advance insulator material and for microelectronics. We have synthesized polyimide- silica composite films and it is shown that such films have much lower dielectric constant as compared to the normal PI films. The above polymer films were prepared by modifying the pristine polymer at the precursor stage of synthesis. We report the results of FTIR, XRD and dielectric studies of films which have been prepared using PMDA-ODA (Poly Amic acid in DMAc) as precursor and Tetra Ethoxy Silane (TEOS)/Silicic acid as modifier It is seen that crystallinity and the dielectric of the composite films depend on SiO2 concentration.

Published: October 2020

Abstract
The research intends the need for an alternative source of energy based on fuel cell. The purpose of the work is to generate electricity from hydrogen fuel cell using H2 gas. The stored energy in form of fuel cell can be further used to operate the automatic grass cutter. The hydrogen, oxygen fuel cell formed from electric energy storage can be obtained by combining aluminium and water. H2 has the highest energy density from all common fuels by weight so that’s why it can be one of the promising substitute energy sources. The hydrogen must be incorporated in a small, less heavy system so that unnecessary weight of the device should be avoided. For cutting the grass, manually handled devices are commonly used, efforts required are more. Also, the old grass cutters are getting obsolete and requires replacement by automatic one, where system will work for guidance and obstacle detection using battery as power source. In these days’ problems like pollution, power cut problem etc. appearing. To deal with such trouble and the help of technology device can be made, which can do its function without stimulating any harmful exhaust, the project will be operated by generating an energy, which can perform operation by using the renewable source of energy like alternate hydrogen fuel. Hence an attempt has been made by combining aluminium and water into some usable form which can absolutely be an alternative for various power generating fuels.

Published: October 2020

Abstract
The physiological roles of isoprene, which is one of the many endogenous volatile organic compounds contained in exhaled breath, are not well understood. In recent years, exhaled isoprene has been associated with the skeletal muscle. Some studies have suggested that the skeletal muscle produces and/or stores some of the isoprene. However, the evidence supporting this association remains sparse and inconclusive. Furthermore, aging may affect breath isoprene response because of changes in the skeletal muscle quantity and quality. Therefore, we investigated the association between the breath isoprene excretion (

The workload corresponded to an intensity of 30% of the heart rate reserve, as calculated by the Karvonen formula. The exhaled breath of each participant was collected during the exercise test.

Authors: Suciatmih  
Published: October 2020

Abstract
Colors variation and aging on cloth can be obtained through dyeing repetition and the application of color reinforcement materials. In the present study, cloth was dyed with dyes from the mixed fungi of Aspergillus and Paecilomyces using three different dyeing repetitions (3, 6, and 9 times), three different mordants (CaCO3, FeSO4.7H2O, and KAI (SO4)2.12H2O), and three different other color reinforcement materials (salt, soda ash, and vinegar). The mixed fungi were grown on mineral salt glucose medium in stationary cultures in dark conditions for 4 weeks. By using the RHS color chart, the range of colors developed on dyed materials was measured. The result showed that different dyeing repetitions and the combination of those with color reinforcement materials had a great effect on the color formation of cloth by the mixed fungi dyes. The optimum condition of cloth dyeing by the fungal dyes depends on color reinforcement materials used. The combination of dyeing repetition and color reinforcement materials on the color formation of cloth by the fungal dyes generated various colors, adding a color variation on textile dyeing.

Abstract

Artocarpus heterophyllus (Ah) is a plant that grows in many parts of Indonesia. Its leaves are widely used for traditional uses, one of which is for facial skin care. The present study was conducted to evaluate the effect of its extract on facial skin smoothness. Ethanol extract of Ah (EEA) was prepared as clay mask formulation (FI: 1, F2: 3 and F3:5%) and then was applied on volunteer face. Skin smoothness improvement was measured using a skin analyzer. Standardization of simplicia and phytochemical screening of EEA were done before the test. Data were analyzed using Kruskall Wallis and Mann Whitney. Standardization yielded as follows: total water-: 5.33%, total water-soluble 15.67%, total ethanol-soluble 13.61% and total ash 10.29%. Smoothness value showed as normal skin with improvement to smooth level on EEA-treated group: FI: 9.4%; F2: 5.6%; F3:10.0%. The highest improvement percentage of skin was found in F3. Statistically, there was significantly different (p=0.046) between F0-F3. The study concludes that F3 is able to improve facial skin smoothness.
