This work investigates the influence of white cow hair as reinforcement in \nCement/Waste paper pulp matrix for structural applications. Cow hairs as natural \npolymer, were sourced from an abattoir, and washed properly in clean water and sun \ndried for 5 days. Paper pulp was prepared by first soaking waste paper in…
In this article, the buckling behavior of tapered Timoshenko nanobeams made of axially functionally graded (AFG) materials resting on Winkler type elastic foundation is perused. It is supposed that material properties of the AFG nanobeam vary continuously along the beam’s length according to the power-law distribution…
Abstract Influence of dicarboxylic acid dopant on growth and characterization of ADP crystal were grown by slow evaporation technique at room temperature. The transparent (ADFU) crystals are yield after a period of 15 days. The X-ray diffraction study reveals that ADFU crystal belongs to tetragonal system. The vibrati…
Fountain solution induced mottling in offset printing manifests as non-homogenous printing area with optical variation has several influencing factors. One mechanism is that the fountain solution from the previous printing unit has no time to absorb into the coating before ink transfer or the ink cannot emulsify the w…
Circuit breaker is an important part of the electrical network. It makes or breaks the network to transmit the electrical energy from one point to another. But every operation of the circuit breaker is associated with switching transients. Switching transients degrade the quality of power transferred through the power…
The first part of this review article lists examples of complete, empirical de novo design that made important contributions to the development of the field and initiated challenging projects. The second part of this article deals with computational design of novel enzymes in native protein scaffolds; active designs w…
The use of medium frequency allows the transformer size to be reduced at the higher power level. Reduction in size of the transformer leads to a reduction in installation area which is of prime concern in many renewable energy resources. But the reduction in size at higher power level comes with the cost of higher los…
ABSTRACT Achnanthidium exiguum is reported for the first time from Salar de Huasco and Salar de Aguas Calientes in northern Chile. The morphological features of the species are described and illustrated with light and electron microscopy photograhs, and agree well with the type material studied by Schoeman & Archibal…
The rapid growth of electric power industry nowadays has change the conventional framework where the power quality issues are being concern. Power quality issue known as power quality disturbances can substantially affect high sensitive utilization equipment such the malfunction of sensitive electronic medical equipme…
Introduction: Titanium Dioxide (TiO2) nanoparticles have potential risks to human health. They were able to enter brain to be detected in the cerebral cortex, cerebellum and hippocampus. Withania somnifera (WS) improve rotenone induced damage in cerebellum.Aim of the work: To study the effects of oral administration o…
Recently Controlling the electromagnetic wave, especially in terahertz range is highly demanded due to the development of practical devices and application systems. In this paper, we propose a scheme to design tunable abnormal reflection structure consisting of molybdenum disulfide (MoS2) array on a grounded SiO2and a…
The paper analyzes a principal capability to transmute neptunium, the main component of transuranium radiowastes (TRW), in lead-cooled fast BREST-type reactor. High-energy neutron spectrum of the BREST-type fast reactor makes it possible either to eliminate neptunium in fission reactions or convert neptunium to pluton…
The paper studies the key techniques of precision cutting of the zona pellucida (ZP) on single-cell level. The article first studies the composition of the ZP and the existing cutting methods, and draws the main difficulties of the cutting process. First, the oocyte is an elastomer, which is prone to deformation durin…
Stable configurations of point radiation defects of tungsten near the surface were investigated within the density functional theory. The emergence of an self-interstitial atom leads to formation of a crowdion. The transformation of this configuration into a configuration with an adsorbed W atom is a thermally activat…
In this paper, we aimed to establish the similarity of dispersion of various metals at high-intensity loading. Characteristics of the dispersing products and the cascade of arising dissipative structures (the inner surface roughness of the destruction centers, the cascade of the slip bands of the crystal lattice, the…
In this study, the effects of the free quenching temperature on mechanical, thermomechanical and thermophysical properties of pigmented polystyrene (PS/TiO 2 ) with 3% of TiO 2 were investigated. Thermal conductivity and thermal diffusivity of the titanium dioxide pigmented polystyrene were measured using a periodic m…
We consider the problem of configuration of the external meniscus formed by the capillary rise of a liquid during immersion of a ribbon-like fiber into the liquid. In the case when the fiber thickness is small, a new analytical solution of the problem is constructed using the asymptotic approach. In this solution, at…
The treatment of polystyrene in sub- and supercritical (SC) freons was studied in comparison with processes in supercritical carbon dioxide. Subcritical freon R22 was shown to be much more effective in saturating polystyrene than subcritical R410a and SC R23 and CO 2 . Subsequent thermal treatment of the samples satur…
본 논문에서는 다중적층 유리의 고속 충돌체에 의한 충돌/침투 파괴 현상을 해석하기 위해 페리다이나믹 동적 해석 기법 을 적용한다. 대부분의 다중적층 유리 구조물들은 다수의 주요 유리층들이 상대적으로 매우 얇은 탄성 필름으로 접착되어서 만들어진다. 따라서 다중적층 구조물의 수치해석 모델을 구성하는 것은 까다롭고 비용이 많이 든다. 본 연구에서는 실제 절 점을 대신하여 가상의 절점들을 주요층들 사이에 위치시키고 상호작용시키는 비국부 가상 층간구조 모델링을 도입하여 보 다 효율적으로 다중적층 구조를 모델링하였다. 또한 고속 충돌체와의 충돌 및 침투 현상을 해석하기 위해…
Abstract The softening and the strength of the welded joints of high-temperature complex alloyed aluminum 1151 alloy sheets fabricated by friction stir welding and nonconsumable electrode welding are analyzed. The strain hardening of the 1151 alloy welds formed by friction stir welding provides a higher level of their…
