Hard facing overlay welding in high chromium carbide is a representative way of extending the fatigue life or recompensing damage, because workpiece surface is uniformly overlay-welded by alloy material. In general, grinding process is currently used for finish due to hardness of weld material. The development of tool…
The ethylene-propylene rubber (EPDM) scrap generated from automobile weatherstrip manufacturing process was used to make a thermoplastic elastomer through blending with polypropylene. The surface activated EPDM powder was obtained by the high temperature and shear pulverizer. The addition of surfactant resulted in mor…

We measured shear viscosity of polystyrene (PS) and poly(butyl methacrylate) (PBMA) particles, with a capillary rheometer, prepared by suspension polymerization with 1.0 wt% hydrophobic silica as a stabilizer by varying the initiator concentration at . PS particles with weight average molecular weight of 66,500 g/mol…
This paper considers the origin and the development of dislocations during crystal growth of multicrystalline silicon. The distribution of dislocations is analyzed statistically. The obtained density functions reveal a characteristic structure, which consists of two maxima with medium and high dislocation densities. T…
Reduction scheme is remarkably useful in the case requiring the repeated calculation procedure. Recently, the efficiency of the reduction scheme has been improved by combining scheme of sub-domain method. But, when the global domain is partitioned into a few sub-domains, sub-domains without constraints can be produced…
In this study, an efficient sequential bridging method to characterize both the particle size effect and concentration effect on the mechanical properties of nanocomposites at high volume fraction is suggested through a molecular dynamics(MD) simulations and micromechanics of composites materials. The Young's modulus…
Chalcogenide based non-volatile Phase Change Memory (PCM) circuits were designed to investigate new emerging non-volatile memory technologies. An overview of the operation of chalcogenide-based resistive PCM for circuit designers is presented. MOSIS fabrication service was used along with Idaho Microfabrication Lab at…
In micro/nano-scale contacts in MEMS and NEMS, capillary and van der Waals forces generated around contacting micro-asperities significantly influence the performance of concerning device as they are closely related to adhesion and stiction of interacting surfaces. In this regard, it is of prime importance to accurate…
The parallel-plate waveguide structure par- tially filled with Left-handed material (LHM) is carefully investigated. It is shown that complex mode is the con- stituent part of complete eigen mode set in the structure independent of parameters of the configuration and op- erating frequency; it means that purely propaga…
Abstract : The purpose of this study was to investigate muscle activity of the lower limbs when walking in jeans in orderto obtain basic information for development of new jeans patterns with excellent movement adaptability. Using three typesof jeans (basic, medium, and slim) with different ease on hip, knee circumfer…
Abstract Layered double hydroxide is synthesized and used in the arsenate adsorption experiments. The shapes of two materials ana-lyzed by TEM showed that unheated material is amorphous in shape, micro-sized while heat treated material showed morecrystallized in shape and nano-sized. X-ray diffraction showed this resu…
No reliable soil test is currently available to assess the potassium (K) status of calcareous soils of Iran. Therefore, the relative efficiency of 10 extractants to predict potentially available K to lowland rice (Oryza sativa L.) was evaluated in 27 calcareous soils. The extracting capacity of the extractants was qui…
Anatomical characteristics of kenaf were investigated in transverse, radial and tangential direction by optical and scanning electron micrograph. Kenaf was made up of bast fibers, wood fibers, vessels and parenchyma cells. Bast fibers were long slender cells with different types of pits. The shape of wood fibers were…
Globally, many countries have identified the potential of nanotechnology in the agricultural sector. Therefore, they are investing significant funds into nanotechnological research. Developing countries also adopt their own nanotechnology programmes specifically focused on applications in agriculture. The development…
The magnetic flux leakage method offers the potential to detect breaks in reinforcing bars resulting from fatigue or pitting corrosion in a non-destructive way.This paper presents on-going and future research, covering the detection of breaks in different specimens with reinforcement layouts by measuring the magnetic…

Core menggunakan serbuk arang bambu apus dengan fraksi volume 5%,10%,15%,20%,25% pada mesh 100 da…
[Objective] This study was to improve the biomass of Navicula tenera, and thus to provide reference for achieving the industrial production of Navicula tenera. [Method] The feasibility of using sewage to cultivate Navicula tenera was preliminarily investigated based on the consideration of regional characteristics; an…
The adsorption of O and N atoms on the Ni(311) surface was investigated by the 5-parameter Morse potential(5-MP) method in detail.For the O-Ni(311) system,there are three surface adsorption states and the fcc-3-fold site is metastable;the frequency of 75 meV[67 meV in high resolution electron energy loss spectroscopy(…
This paper introduces a conceptual design of a combined scroll expander-compressor unit for a fuel cell. Since air discharged out of the fuel cell stack has still high pressure energy, some power can be extracted from the air by directing it to pass through an expanding device. Such extracted power can be used to driv…
