Functional sensing materials with desirable responses to a particular quantity of interest can be an enabling technology for successful development of sensors that can be deployed in a wide variety of applications. Au nanoparticle–incorporated metal oxide–based sensing layers have recently shown significant promise as…
The structure of the diffusion regions in antiparallel magnetic reconnection is investigated by means of a theory and a Vlasov simulation. The magnetic diffusion is considered as relaxation to the frozen-in state, which depends on a reference velocity field. A field-aligned component of the frozen-in condition is prop…
This paper describes investigations of Eurofer97 and oxide dispersion strengthened version of this steel, in as received state and after annealing. Vickers hardness test was performed on the as received specimens and after annealing at various temperatures to obtain information about development of the strength of stu…
Metasurfaces presenting a phase-gradient are designed at 10 GHz and are proposed to steer an antenna's radiated beam from broadside towards endfire direction. The metasurfaces are composed of both inductive and capacitive grids and the phase-gradient is achieved by modifying the elements in the inductive grid. Such ph…
This study aimed to examine the relationships between the characteristics of charcoal from Qualea parviflora Mart. using canonical correlation analysis. Five trees were analyzed in such way that 5-cm thick discs were removed from each tree at the base, DBH (1.30 m), middle and top sections. The wood was carbonized in…
Farooq A ShiekhAvalon University School of Medicine, Curaçao, Netherlands AntillesCancer is not one, but many heterogeneous diseases1 with complex genetic and epigenetic alterations2,3 that annually afflict millions of people worldwide. Despite the progress in understanding the molecular mechanics of cancer,4 its trea…
Due to the necessity of obtaining a surface that is resistant to wear and oxidation, hydraulic cylinders are typically coated with hard chrome through the process of electroplating process. However, this type of coating shows an increase of the area to support sealing elements, which interferes directly in the lubrica…
Xiaomin Yi, Fuli Wang, Weijun Qin, Xiaojian Yang, Jianlin Yuan Department of Urology, Xijing Hospital, Fourth Military Medical University, Xi'an, Shaanxi, People's Republic of China Abstract: Near-infrared fluorescence (NIRF) imaging is an attractive modality for early cancer detection with high sensitivity and multi-…
The present investigation shows the wear behaviour of as-cast and heat treated, A356 aluminium alloy reinforced with SiC and Graphite particles subjected to different ageing durations. The liquid metallurgy technique was used to fabricate the composites. The reinforcement content was varied from 0 to 9 % by weight in…
More recently, Titanium and aluminum alloys are gaining more interests to be implemented in hydro-forming applications. It is necessary to predict forming limits for these sheet alloys. Forming limits play an important role in metal forming processes. Forming limit diagrams, present the limit strains for various linea…
This paper presents a new approach for processing images of woven fabrics to determine the warp-weft densities. This approach includes three main steps, namely; image transformation, image enhancement, and analyzing signals of the image. In the experimental process, 19 different woven fabric images were scanned at a h…
Three‐dimensional cellulose gel was prepared by a crosslinking of the cellulose chains using epichlorohydrin in the presence of the NH 4 OH, and the TiO 2 nanoparticles which were fixed on the surface of cellulose gel to form microcrystalline cellulose gel/nanoTiO 2 composites (MCC‐TiO 2 ). The composites were charact…
With the increasing demand for functionalised textile materials, industry is focusing on research that will add novel properties to textiles. Bioactive compounds and their benefits have been and are still considered as a possible source of unique functionalities to be explored. However, incorporating bioactive compoun…
The purpose of this paper is to outline the effects of dye-sensitised solar cell (DSSC) configuration on useable output power provided through low-power, step-up DC-DC converters. It is shown that by connecting DSSCs in series rather than in parallel, higher power conversion efficiency is achieved due to increased cel…
Sulphur-oxidizing bacteria strain SO-1 and strain SO-2 have been isolated respectively from leaching pulp of zinc and copper concentrates. The cells of isolated bacteria are rods with the size of 0.3-0.5 x 0.7-2.0 mkm. They are capable of oxidizing elemental sulphur and tetrathionate with optimal growth temperature of…
In this paper control of shunt active power filter with sliding mode controller is considered. The compensation by shunt active power filter involves harmonics mitigation due to three phase non linear loads. The sliding mode controller is used to regulate voltage of the capacitor used in inverter. The sliding mode con…
Values of hardness, wear resistance, and contact endurance limits for steels VKS-7 and VKS-10 found experimentally in various test conditions are presented. Characteristics of mechanical properties of heat-resistant steels are improved by the use of the new complex technology of thermal and chemical-thermal treatment…
Power Transformers are one of the most critical component of power system in which transformer oil is used for both insulation and cooling purposes. Mineral oil plays a vital role in insulation system of the transformer. In transformer, withstand strength of insulation materials mainly depends on the properties of the…

The effect of the energy on the dynamics of electroerosive surface wear of the accelerating channel in a coaxial magnetic plasma accelerator is studied. The energy supplied to the accelerator is varied by cutting off the current pulse tail by a trigatron arrester at different instants of times. It has been ascertained…
