Nickel-Titanium shape memory alloy (Nitinol or NiTi) is a fascinatingmaterial for dental applications. In this work the alloy has been produced by powdermetallurgy approach. The effect of Mg and Zn additives studied on the; hardness,porosity percentage, and corrosion rate has been studied. Master Samples (withoutaddit…
In this work production of aluminium matrix composites with silicon carbide (α-SiC) as reinforcement material were fabricate, the particle sizes of (SiC) used were (500μm- 250 μm and125 μm), with weight percentage of (7.5% - 10% - 15%) from silicon carbide for eachparticle size. The single action pressing was used as…
Presented in this paper is a new study of the AASHTO equivalency factorsof military tracked armoured vehicles on flexible pavement. Two types of militarytracked armoured vehicles were studied, namely Challenger 2 tank and MT-LB-Ttracked armoured vehicle. A measure of the damaging effect of military trackedarmoured veh…
目前世界各國對於高放射性廢棄物的最終處置辦法中，「深層地質處置」是較為可行且必要的一種處置方法，尋找一個適合放射性廢棄物處置場場址，須考慮到許多的因素，包括水文、地震、地層構造、與地質礦物組成等，因此量測高放射廢棄物污染更顯為重要。^(99)Tc為人造元素、^(99)Mo之子核種，是核分裂產物中產率較高的核種。核能設施核分裂之燃料^(235)U，核分裂後的產物^(99)Mo可連續衰變生成^(99)Tc，由於^(99)Tc半衰期長且遷移性高，因此都以^(99)Tc作為監控核設施或核廢料環境的主要核種之一。本研究初始以^(99)Tc之同位素^(99)mTcO_4^ -作真實樣本之模擬，再配合使用TEVA樹脂做樣本的前處理，以探討分離條…
Ni complex was prepared from bipyridine dicarboxylic acid and Ni salt. Then, the Ni complex was reacted with Al salt in dimethyl formamide in an autoclave to prepare metal-organic framework (MOF) compounds containing Ni-complex. IR analysis indicated disappearance of absorption peaks related to carboxylic acid, and ni…
How to apply biochar in non-till field How to prevent runoff of biochar Future Biochar Research at the ISTCWe will attempt to explore the pitfalls of biochar, which impedes its current massive production and extensive application.
The capability of predicting accurately the detailed behaviour of phase change materials (PCMs) undergoing a phase change is of paramount importance when designing practical systems using this kind of materials. In particular, the prediction of the dendrite growth dynamics is quite vital since it gives the possibility…

Soluble methane monooxygenase is a bacterial enzyme that converts methane to methanol at a carboxylate-bridged diiron center with exquisite control. Because the oxidizing power required for this transformation is demanding, it is not surprising that the enzyme is also capable of hydroxylating and epoxidizing a broad r…

In this review we describe a number of skin substitutes which are under development for advanced wound healing therapies and for use as animal alternative (in vitro assays). Skin tissue engineering is a multi-disciplinary subject which requires each construct to be specifically designed for its particular future appli…
Hoy en dia el avance tecnologico ha evolucionado vertiginosamente en los ultimos anos ha conducido al desarrollo innovador de muy diversos productos fundidos de los cuales, se demanda una alta calidad de las materias primas para la fabricacion de moldes, en los cuales requieren grandes cantidades de arena que, junto a…
The Remote-Handled Transuranic (RH-TRU) Content Codes (RH-TRUCON) document describes the inventory of RH-TRU waste within the transportation parameters specified by the Remote-Handled Transuranic Waste Authorized Methods for Payload Control (RH-TRAMPAC). The RH-TRAMPAC defines the allowable payload for the RH-TRU 72-B…
Introduccion. Se ha encontrado que la aplicacion comercial de arcillas pilarizadas como catalizadores se ha dificultado principalmente por su prolongado tiempo de preparacion. Sin embargo, se encuentran reportadas varias tecnicas para modificar arcillas por incorporacion de polihidroxocationes modificando la naturalez…
Ticari standartlara uygun boyutlarda blok verebilen, kesilip parlatılan veya yüzeyi işlenebilen ve taş özellikleri (malzeme özellikleri) kaplama taşı normlarına uygun olan her türden taş, (tortul, magmatik ve metamorfik) ticari dilde "mermer" olarak bilinmektedir. Bu tanım uyarınca kalker, traverten, kumtaşı gibi sedi…
The article deals with the software for a new protection system of the VR-1 training reactor which consists of the independent power protection and the operational power measuring systems. Both sys...
Abstract : The current paradigm of drug delivery using nanotechnology has been focused on coupling chemotherapeutic molecules to nanoparticulate delivery systems. In this work, we propose that pH-triggered aggregation alone of nanoparticles (that are non-toxic when not aggregated) can induce death in breast cancer cel…
The effect of 1, 8-Diazabicyclo [5.4.0] undec-7-ene (DBU) on corrosion of Alloy 600 (UNS N06600) coupons was studied at room temperature. The equivalent circuit representing the frequency response of DBU in an aqueous solution on Alloy 600 is presented. The Nyquist plots showed very good corrosion protection initially…
The aim of this work is to study some fundamental of tracks experimentally and theoretically in the detector CR-39 of thickness 250 µm, A computer program (TRACK-TEST) was used for calculating track parameters. The results show that a maximum energy lost is occurred when the energy of alpha particles is about 1.5 MeV,…
