Jalil MA, Sinha RC, Miazi MOG, Mahabubuzzaman AKM, Islam MK (2010) Analysis of jute yarn quality by the change of drafting zone of d drawing frame. J. Innov. Dev. Strategy 4(2), 18-22. thir In drawing frame, different pin settings are used to produce fine jute yarn in apron draft spinning frame. Among the pin settings…
The sheet for electromagenetic interference (EMI) shielding was prepared with slurry made by the mixture of binder, methyl ethyl ketone, cyclohexanone and metal powder. We tried to enhance the shielding efficiency by adding carbon nanotube (CNT), which has known as highly conducting material. Surface and component ana…
Explicit finite element approaches exhibit several advantages over implicit method including easy treatment of dynamic effects and instability problems. These problems also arise for materials and structures at small length scales. At small length scales however size effects are present and are often treated with stra…
Cryptand resins have been synthesized from 1-aza-18-crown-6 macrocyclic ligand attached to styrene (2th petroleum in 4th class hazardous materials) divinylbenzene copolymer with crosslinkage of 1%, 2%, 10%, and 18% by substitution reaction. The synthesis of these resins was confirmed by the content of chlorine, elemen…
In this work, the stretch flangeability of a TWIP steel sheet sample was investigated both experimentally and numerically through the hole expansion test. Uniaxial tension and disk compression tests were performed to characterize the flow behavior and plastic anisotropy for the TWIP steel sheet sample. The punch load‐…
The self-assembly of Co(OAc)·4H2O with H2tbip and bipy (H2tbip = 5-tert-butyl isophthalic acid, bipy = 4,4'-bipyridine) generates one new complex, [Co3(tbip)2(Htbip)2(bipy)]n, which has been characterized by elemental analysis, X-ray diffraction, and IR spectroscopy. Single-crystal X-ray analysis reveals that it cryst…
Administration of DDW (deuterium depleted water) represents a proper method to reduce deuterium in biological systems.In present study experiments were performed in order to observe the deuterium's concentration decrease in laboratory animals' bodies using DDW as depleting agent, the main ingredient for the commercial…
This paper review the opportunity of a new natural fibres, sugar palm, as the reinforced the polymer composites. Some characteristics of the sugar palm fibre were discussed based on the work reported some researcher elsewhere. Sugar palm fibre was the new natural fibre in literature on natural composites. Still a litt…
In this research Sr‐hexaferrite powder was synthesized by a sol‐gel auto‐combustion route using two different fuels (glycine and citric acid) and two different basic agents (ammonia and trimethylamine). N‐decyltrimethylammonium bromide (C13H30BrN) was also employed as a cationic surfactant. The results showed the fine…
A 128128 elements cylindrical liquid crystal (LC) lens array with electrically controllable focal length is proposed. The cylindrical LC lens array uses transparent indium tin oxide (ITO) films as electrode, avoiding to affect the optical path operating in the voltage-off status. As the top electrode of the cylindrica…
Polyorganosiloxane modified polyurethane (PDMS-PU) polymers were prepared from copolymerization of ,-hydroxypropyl terminated polyorganosiloxane with isophorone diisocyanate (IPDI), polypropylene glycol (PPG), and 2,2-bis(hydroxymethyl) propionic acid (DMPA). Hydrophobic polyorganosiloxane was introduced in polyuretha…

Simultaneous removal reaction for NOx, soot over Pt catalysts using various as support was studied. The catalytic tests ware carried out injectin NO, soot, NO and soot simultaneously on each catalysts. As results, it showed different NOx removal efficiency and soot oxidation rate according to various kinds of . Onset…
This study was performed to recycle Propylene Glycol Monomethyl Ether Acetate (PGMEA) from Liquid Crystal Display (LCD) industry emission as a waste organic solvent by using a multistage distillation column and tried to decide optimum reflux ratio. From the final experiment result, it was confirmed ; in case the sampl…
본 연구에서는 암모늄염 처리에 의하여 리기다 소나무를 바탕으로한 재료의 난연성을 시험하였다 . 실온에서 3종류의 암모늄염 즉, ammonium sulfate, monoammonium phosphate, 그리고 diammonium phosphate의 20 wt% 수용액에 각각 리기다 소나무를 함침시켜 건조시킨 후 콘칼로리미터(ISO 5660-1)를 이용하여 그들의 연소성을 조사하였다. 암모늄염으로 처리한 시험편들은 미처리된 시험편에 비하여 연소억제성을 향상시켰다. 그러나 CO의 발생량은 증가하여 정도에 따라 독성 영향을 미치는 것으로 보여졌다. 또한 미처리된 순수 시…
We have synthesized boron (or phosphorous) doped silicon nanoparticles (Si-NPs) by a solution process. The surfaces of the Si-NPs were terminated with various alkyl groups to form a protecting layer. The Si-NPs were characterized by UV-Vis, PL, FTIR, and NMR. Through a microwave sintering process, the crystalline thin…
Using high speed video camera technology,the physical experiment on material damage under expansive action of static cracking agent was carried out.The dynamic fracture mechanical behavior of cast material with cut slot under expansion was studied.The regularity of crack propagation velocity and acceleration was achie…
The effect of forging ratio and ingot size on eutectic carbide Inhomogencity of D2 forged bars and the effect of refining process and the surface state of electrode on the oxygen content have been studied.Results show that forging ratio and ingot size have strongly influenced on eutectic carbide Inhomogencity of D2, n…
