This paper presents the results of building an oscillation analysis tool on a motor vehicle with an oscillating isolation pillow as a basis for calculating and designing electromagnetic damping pillows to reduce vibrations on this motor vehicle.
A kesterite Cu2ZnSn(SxSe1-x)4 (CZTSSe) thin film is fabricated on a Mo-coated glass substrate by a non-vacuum spray pyrolysis method from an aqueous precursor solution containing Cu(NO3)2, Zn(NO3)2, Sn(CH3SO3)2 and thiourea followed by sulfurization and selenization at 600°C. The fabricated CZTSSe thin film shows high crystallinity with optimal Cu-poor and Zn-rich compositions, which is confirmed by the X-ray diffraction pattern, Raman spectrum, and Energy dispersive X-ray spectroscopy results.
In this paper, we study laws of large number for random weighted sums of random variables with regularly varying tailed and application. Firstly, we use the theory of slowly varying functions to establish the law of large. Then, we apply this result to estimate non parametric regression models by the k-nearest neighbors.
This study investigates the impact of crystal surface orientation on aqueous solutions confined in charged nanopores by using molecular dynamics simulations. Pore walls have been modeled as (100) and (110) silicon layer.
Intermolecular interactions between CH3OCHX2 (X = H, F, Cl, Br, CH3) with carbon dioxide (CO2) and water (H2O) were theoretically investigated using high-level ab initio methods. The addition of an H2O molecule to the CH3OCHX2∙∙∙CO2 complex enhances the stability of ternary complexes. This finding supports the increase of solubility of CH3OCHX2 in supercritical CO2 with the presence of H2O.
We observed the propagation of shockwave induced by focusing a nanosecond laser pulse on the surface of an epoxyresin block. The evolution of shockwave was observed within the first 1000 ns from irradiation. The shockwave energy was calculated based on the point-explosion model. The result indicated that the ablation process converted 60% of laser pulse energy into shockwave energy. We suggest that this result can be used for a simple estimation of shockwave energy in applications that use laser ablation of solids in atmospheric condition.
The present review paper provides a comprehensive examination of alcohol consumption, focusing on its metabolism and health effects. Alcohol, a substance that depresses the central nervous system (CNS), is widely consumed and holds significant social and cultural significance. Understanding the metabolism of alcohol is vital for comprehending its effects on the human body and the factors influencing alcohol-induced health outcomes. This review aims to synthesize existing literature to shed light on the intricate interplay between alcohol consumption, metabolism, and health outcomes.
This review aims to revise the methods of isolation and identification of Bifidobacteria from commercial yoghurt and its use in ginseng fermentation. Isolation methods for Bifidobacterium spp. include various selective media which is followed by the strain identification using Polymerase Chain Reaction and sequencing or carbohydrate fermentation patterns.
