The applicability of carbon nanotube (CNT) to slow sand filtration for the removal of bacteria was studied using scanning electron microscope and column experiments. The morphology of CNT were investigated using scanning electron microscope and the CNT looked like a skein serving bacteria favorable site for adhesion.…
Ti-13Nb-13Zr alloy produced via powder metallurgy was submitted to heat treatment under various conditions and the effects on microstructure and elastic modulus were investigated. Heat treatment was performed using temperatures above and below α/β transus combined with different cooling rates – furnace cooling and wat…
Elektrik şebekesinin en önemli elemanlarından biri olan güç transformatörünün mekanik bütünlüğünü değerlendirmek için çeşitli teşhis yöntemleri vardır. Tarama Frekans Cevap Metodu (TFCM) ile transformatörler yerinde analiz edilmekte ve arızalı durumlar tespit edilerek gerekirse yerinde yapılan müdahaleler ile giderile…
Base on the magnetization and magnetostriction measurement, this paper proposed a generalized 3D finite element numerical model, which can be used to analyze electromagnetic vibration of laminated cores including electromagnetism and magnetostriction effects. And then the acoustic field around the transformer was anal…
Electric-double-layer field-effect-transistors (EDLFETs) were fabricated using 10.5-12.9 nm thick YBa2Cu3O7(YBCO) films and N, N-Diethyl-Nmethyl-N-(2-methoxyethyl) ammonium bis (trifluoromethanesulfonyl) imide (DEME-TFSI), and critical temperature (Tc) and vortex behavior were evaluated in the devices. Decrease in she…
Undoped Cadmium sulfide (CdS) nanocrystalline thin film and doped Zinc are prepared by chemical bath deposition (CBD) technique. The characterization of the product was done by UV-VIS absorption, x-ray diffraction (XRD) and atomic force microscopy (AFM). The effect of zinc content on structural, morphological and seve…
The WWR-M is a light-water cooled and moderated heterogonous research reactor with a thermal output of 10 MW. The final decommissioning planning for the Kiev’s research reactor WWR-M is in progress now. The general dismantling strategy consists of the dismantling and removal of the separate bulky elements as whole pie…
This paper presents a summary of IAEA activities concerned with the decommissioning of research reactors and nuclear facilities in general. These activities are undertaken in line with IAEA’s role in establishing safety standards for health and environmental protection, including associated legal and policy frameworks…
The present study has aimed at investigating some local agricultural wastes as sources for the production of a-cellulose; these included: sugarcane bagasse, rice straw, durra stalk and groundnut shell. A mixture of toluene and ethanol in the ratio of 2:1 was utilized in solvent extraction, for 6 hr, to remove wax and…
Çalışmada, gamma ışımasına tabi tutulmuş geri dönüştürülmüş yüksek yoğunluklu polietilen polimerin (g-HDPER) bitüm içerisinde katkı malzemesi olarak kullanılabilirliği kimyasal ve fiziksel deney yöntemler ile incelenmiştir. Geri dönüştürülmüş yüksek yoğunluklu polietilen malzeme (HDPER), gamma ışıması ile radyasyona t…
The research, whose results are presented, is aimed at determination of development of moulds number in wood chips under different storage temperatures. The experiments were carried out with the moisture of samples 65%, 22% and 1%. During the long-term storage the effect of water content in material on development of…
Natural fiber is incompatible with hydrophobic polymer due to its hydrophilic nature. Therefore, surface modification of fiber is needed to impart compatibility. In this work,superheated steam (SHS)-alkali was introduced as novel surface treatment method to modify oil palm mesocarp fiber (OPMF) for fabrication of bioc…
A framework is developed and implemented to characterize and model in plane fibre misalignment in Non-Crimp fabrics (NCF). Image analysis based on fast Fourier Transform and correlation analysis is used to characterise in plane fibre misalignment in a carbon fibre ±45º NCF. It is found that fibre misalignment is signi…
The effects of variations in copper content on the metallurgical, mechanical, and fracture properties of pearlitic rail steels with a base composition (in wt pct) of 0.9 C, 1.0 Mn, 0.35 Si, and 0.01 Ti were evaluated. Six industrial heats with copper content ranging from (in wt pct) 0.07 to 0.85 were cast, re-heated,…
The aim of our study was to evalute the effect of chitosan on non- specific immunity and survival rate of Cyprinus carpio challenged with Aeromonas hydrophila. A total of 80 common carp (36.4 ± 0.73 g) were devided into four dietary groups: The first group (G1) was served as control fed on chitosn-free diet, the secon…
The purpose of this study was to investigate differences in cutaneous thermal sensation thresholds and the inter-threshold sensory zone between firefighters (8 males) and non-firefighters (9 male students). The results showed that; 1) firefighters’ skin temperatures on the hand and calf were higher than those of stude…
It has always been recognized that radiation measurements and dosimetry (M &8; D) play a crucial role in developing radiation protection programs for workers and members of the public, particularly as they relate to mitigating potential health risks from exposure to radiation. The National Council on Radiation Protect…
The dimensionless extinction constants of particulate matter for F-76 diesel and JP-8 aviation fuels were measured at both 633 nm and 853 nm in the transmission cell where the simultaneous gravimetric measurement of PM concentration is compared to the light extinction measurement. For the F-76 diesel PM, the average v…
