The dependence of a scalar measure of the structural changes occurring in a material under plastic deformation on a plastic strain measure and the dependence of a free energy measure on a structural change measure are constructed using experimental data that allow the expended plastic work to be divided into a latent…
In this study, a possible method of reducing the flashover stress is achieved by the effect of an additional magnetic field in the transverse direction on the main applied electric field. The degree of vacuum used in this study was [Formula: see text] Pa. The magnetic flux density B employed in this study extends from…
Lo scopo di questa tesi e fare il punto sui risultati ottenuti nello studio dei materiali di prima parete dei reattori a fusione, concentrando l' attenzione sul problema di accumulo e rilascio di D e T nel tungsteno, materiale scelto a tal scopo.
A partir de la tecnica de molta de ball milling s’adona que es possible sintetitzar pols d’alumini obtenint com a producte una lamina enganxada a les parets dels pots. Es per aixo que s’ha treballat per establir les condicions ideals per obtenir lamina de manera continuada amb aquesta tecnica. Es parteix de particules…
In this study, Magnetic-Cored Dendrimers (MCD) terminalized with amine groups were synthesized, characterized, and investigated to adsorb lead, cadmium and nickel ions from aqueous solutions. Magnetic core was synthesized by co-precipitation method using ferric(Ⅲ)chloride, ferrous (Ⅱ)sulphate, ammonium hydroxide with…
Actualmente en la industria del automovil, para conseguir soldar dos chapas de acero Usibor® 1500 con un recubrimiento de Aluminio Silicio es necesario un proceso previo. Dicho proceso denominado proceso de ablacion, se basa en la eliminacion de 30-50μm del recubrimiento de AlSi mediante laser. Despues de realizar est…
Electron diffraction from thin films can be recorded in the TEM with either convergent beam (CBED) or parallel beam (SAED, NBD) illumination. Although CBED carries a wealth of information from single crystalline regions, parallel illumination is preferred for the structure examination of either nanocrystalline (nc) or…
Zinc oxide and many other materials have long been used in thermoelectric devices for Waste heat recovery to convert heat into electricity. The performance of these materials depends on the figure of-merit ZT (= S2σ T/κ), where S is the Seebeck coefficient, σ is the electrical conductivity, κ is the thermal conductivi…
La tecnologia dels ultrasons s’empra satisfactoriament per l’avaluacio de la precarrega en perns roscats. Els materials mes comuns, com els aliatges basats en ferro y alumini ja han estat caracteritzats i el seu comportament acusto-elastic es conegut i ha estat documentat en la literatura. En canvi, no s’ha publicat…
THP (Thermal Hydrolysis Process) was carried out for the sludge vloume reduction and reuse of sewage sludge according to amount of the dehydrated sludge injection. In the experimental results, it was determined that the utilization of high concentration carbon source was possible with the THP process after anaerobic d…
The effects of cobalt oxide addition on the microstructure and electrical properties of CuZn ferrites were investigated. CuZn ferrites with compositions of (CuO)0.2(ZnO)0.8(Co3O4)x/3 (Fe2O3) 0.986-2x; x = 0 , 0.02, 0.04, 0.08, 0.1 were synthesized using a solid state reaction. It was observed that the addition of coba…
In Nature there are twenty proteogenic amino acid ‘building blocks’, from which proteins and enzymes are constructed. These proteogenic amino acids confer activity to enzymes; however there are many instances where the chemistries provided by these ‘building blocks’ are expanded upon. Nature recruits an array of cofac…
Los fotopolímeros son unos materiales fotosensibles interesantes para el registro de elementos ópticos difractivos. No obstante el registro de perfiles de fase abruptos, como las redes de diente de sierra, presenta problemas por los rápidos cambios que tienen lugar en la superficie de estos materiales. En este trabajo…
Digital printing technique is used for a wide variety of substrates, one of which are PVC foils.Samples used in this research were printed by digital ink jet printing technique using Mimaki JV22 printing machine and J-Eco Subly Nano inks.As printing substrates, two different types of materials were used (ORACAL 640 -P…
En este proyecto se realiza la caracterizacion reologica y de memoria de forma de laminas de dos grados comerciales de Poli (Acido Lactico) (PLA), el PLA 4032D y PLA 2002D, modificadas con agente reactivo SAmfE mediante extrusion-reactiva (REX) y posterior calandrado, con la finalidad de obtener una mejora en las prop…
A preliminary shielding analysis on the transport of the Chinese helium cooled ceramic breeder test blanket module (HCCB TBM) from France back to China after being irradiated in ITER is presented in this contribution. Emphasis was placed on irradiation safety during transport. The dose rate calculated by MCNP/4C for t…
Abstract A study of the correlations between plasma parameters, gas ratios, and deposited amorphous carbon film properties is presented. The injection of a C4F8/Ar/N2 mixture of gases was successfully used in an inductively coupled plasma system for the preparation of amorphous carbon films with different fluoride dop…
This paper researched dismissal of a migrant worker who came to this country under Employment Permit System, especially when the employer reported employment alteration to the head of an employment security office. According to Article 17 of the ‘Act on the Employment, etc. of migrant workers’, “every employer shall,…
본 논문에서는 조영중강 MRI 검사 시 T1 effect를 만들기 위한 물리적 매개변수 중 대표적인 TR과 TE가 가돌리늄과 결합한 H 1 스핀의 신호강도에 어떤 영향을 미치는지를 정량적으로 평가 분석하고자 하였다. 이를 위해 MR 가돌리늄 조영제인 0.5 mol Gadoteridol로 제작된 MR팬텀을 이용하여 1.5T MRI 장비에서 FSE(Fast Spin Echo)시퀀스로 실험하였다. 이때 FSE 매개변수 중 TR과 TE의 값들을 서로 달리하였다. 이때 TR 수치는 각각 200, 250, 300, 350, 400, 450, 500, 550, 600 msec,…
The Lindemann and Frenkel mechanisms of melting, as well as the Bachinsky, Frenkel, and Eyring molecular mechanisms of liquid friction, have been reviewed. The conclusion is drawn that no impartial theories of melting and flow have yet been developed.
