The staggering cost of bringing a drug to market coupled with the extremely high failure rate of prospective compounds in early phase clinical trials due to unexpected human toxicity makes it imperative that more relevant human models be developed to better predict drug toxicity. Drug-induced nephrotoxicity remains es…
It is argued that the anomalous Hall conductivity of ferromagnetic systems is fully determined by the response of the orbital momentum given by the so-called free electron currents to the gradient of the electrochemical potential. It is shown that for perfect Bloch systems it coincides with the well-known expression i…
A facile method has been developed to prepare highly dispersed α-MoC1-x in porous silica. By utilizing C atoms in methyl modified silica supports, α-MoC1-x/SiO2 was obtained via insitu carburization. The obtained samples exhibited high activity for CO hydrogenation.
Kekuatan hasil lasan dipengaruhi oleh tegangan busur, besar arus, kecepatan pengelasan, besarnya penembusan dan polaritas listrik. Penentuan besarnya arus dalam penyambungan logam menggunakan las busur mempengaruhi efisiensi pekerjaan dan bahan las. Untuk itu akan dilakukan penelitian las SMAW sambungan T dengan varia…

Abstract A high performance transesterification catalyst, KF/Mg2Fe is synthesized by loading/dispersing KF in mesoporous Mg—Fe bi‐metal oxides with a Mg/Fe molar ratio of 2.
Comprehensive and sophisticated in its approach, Metalsmithing for Jewelry Makers is the ultimate reference for jewelry makers of all levels. Exploring a wide range of both precious and non precious metals, traditional methods are examined alongside contemporary styles and adaptations to offer a unique and inspiration…
Materials Science A convenient route for preparing monolayer graphene is via chemical vapor deposition of hydrocarbons onto copper substrates held at elevated temperatures. Kidambi et al. examined how changes in process conditions affect the growth chemistry with several in situ techniques, including x-ray photoelectr…
Skin and leather characteristics of hair-type goats were studied in relation to their sex and age, using 100 randomly-selected skin from goats reared in east west Iran. Mean weights of skin and leather were 859.2±35.2 and 357.4±16.2 g, and the length and width of leather ranged from 60 to 121 and 41 to 87 cm, respecti…
In this paper, using first-principles calculations the electronic and magnetic structure of trans- and cis-polyacetylene based magnetic tunnel junctions is investigated. Energy minimization calculations are performed to obtain the equilibrium bonding length at the metal/polymer interfaces. Magnetic proximity-induced s…
Algumas das irradiações a que o homem é submetido podem ser modeladas por um fantoma de voxels acoplado a um código Monte Carlo (MC) que simule o transporte da radiação pelos órgãos e tecidos do fantoma, a interação desta com os átomos constituintes do meio e a avaliação da energia depositada em regiões de interesse.…
Suspended micro-beams made from aligned carbon nanotubes and parylene deflect reversibly in an ac field and the deflection rate is three orders of magnitude greater than those for existing devices. The direction of beam deflection is determined by the area moment of inertia and the actuation mechanism involves rapid a…
The Sentinel 2 mission shall ensure the continuity and enhancement of Landsat and SPOT data and sustain operational land services in the frame of the Global Monitoring for Environment and Security (GMES) initiative. Sentinel-2 is designed to image the Earth’s landmasses from its orbit for at least 7.25 years. The Mult…
We theoretically investigate charge order and nonlinear conduction in the quasi-two-dimensional organic conductor β-(meso-DMBEDT-TTF)2PF6 (DMBEDT-TTF=dimethylbis(ethylenedithio)tetrathiafulvalene). Within the Hartree-Fock approximation, we study the effects of structural distortion on the experimentally observed check…
Microtubules (MTs) are cytoskeletal protein polymers orchestrating a host of important cellular functions including, but not limited to, cell support, cell division, cell motility and cell transport. We construct a toy-model of the MT lattice composed of classical vector Ising spins (dipole moments) representing the t…
The article describes the defects of airfoil shroud platforms of the high pressure turbine of an NK-36ST engine for ground application and shows corrective actions for defect elimination. The structure of a light airfoil shroud platform that can increase the blade lifetime is introduced.
This contribution proposes an identification technique of the parameters which are needed to minimizing power consumption of a City-Bus Equipped with Permanent Magnet Three-Phase Synchronous Motors. A constrained optimization problem is formulated and its solution is approximated by exploiting local flatness and physi…
The lifetime of the transformers is largely affected by overheating of windings and then the insulation ages and it reduces its electrical insulating properties. Therefore, the proper placing of the relevant parts of the transformer can help to ensure more uniform distribution of temperature field and thus to increase…
Pauline L. Waalewijn‐Kool, Maria Diez Ortiz, Nico M. van Straalen and Cornelis A.M. van Gestel Department of Ecological Science, VU University, Amsterdam, The Netherlands SCOPE Zinc oxide nanoparticles (ZnO‐NP) are used in sunscreens with the potential of being released in the environment. This research focuses on how…
