Σκοπός της παρούσας πτυχιακής εργασίας είναι να μελετήσουμε τις βιολογικές επιδράσεις της ηλεκτρομαγνητικής ακτινοβολίας στον άνθρωπο και κατ’ επέκταση να επισημάνουμε τους τρόπους προστασίας για την υγεία μας. Ο αναγνώστης θα είναι σε θέση να κατανοήσει τη λειτουργία των συστημάτων διαθερμίας βραχέων κυμάτων και υπερ…
Magnetic susceptibility χ, electrical resistivity ρ, thermoelectric power (Seebeck coefficient) S and X-ray diffraction (XRD) measurements of Laves phase compound HfV_2 were measured in the temperature T range from 4.2 to 300 K under magnetic fields B up to 17 T and pressures P up to 1.2 GPa. The data of χ and ρ show…
Este trabalho apresenta o resultado da adição de fibras vegetais de bambu e cana-de-açúcar nas propriedades mecânicas do concreto. Para este trabalho foram confeccionados corpos-de-prova cilíndricos e prismáticos nos quais foram adicionados 2% e 5% em volume das fibras à massa do concreto. Após a cura, conforme NBR 57…
Рассмотрена модель накопления повреждений в деталях машин и конструкций, основанная на теории фракталов. Скрытый процесс разрушения, предшествующий образованию макроскопической трещины, связывается обычно с накоплением микроповреждений. Разработаны различные модели накопления повреждений и роста трещин под действием с…
From Valentine et al, 1968. Biochemistry 7:2143-52 ### Rationale: For the highest resolution with negative staining, there should be little or no support film, but some support is necessary to hold the protein. In this method the proteins are supported by a carbon film and "embedded" in a film of uranyl acetate. The f…
Impact toughness and lateral expansion of the irradiated surveillance specimens for VVER-1000 reactor pressure vessel have been defined using Charpy impact test. The analysis of experimental data has revealed a linear correlation of these characteristics. It was shown that a slope of the regression line is practically…
Glass -ceramic material as main component in aerospace application (shuttle), bio-material for the veneering of metal restoration in destroy. In this work glass-ceramic from raw material (Oxides + BaO) was prepared. The XRD analysis showed that the heat treatment causes a very rapid crystallization process and at 900…
No-Fine concrete filled double steel tube columns (CFDST) are being increasingly used for structural applications. It has been used for submerged tube tunnels, nuclear containment, liquid and gas retaining structures, vessels under external pressure in very deep water and for compression members in offshore constructi…

L-Ornithine is an important chemical used in the food and pharmaceutical industries. The Lee group reports the development of metabolically engineered Corynebacterium glutamicum ATCC 13032 for the highly efficient production of L-ornithine. For the development of an efficient producer, they successfully employed ratio…
Um compósito é um material formado a partir da mistura de dois ou mais constituintes imiscíveis que diferem entre si na forma e na composição química. Os materiais compósitos apresentam propriedades significativamente diferentes das propriedades dos seus constituintes.
Every two years the IEEE DEIS selects an individual in recognition of sustained leadership, support, and contributions to the advancement of the field of electrical insulation. This award, which was first given in 1992, is named in honor of the late Eric O. Forster, for his distinguished service on behalf of DEIS. The…
A bureta é um tubo graduado, estreito, com a extremidade inferior alongada, na qual existe uma torneira. É utilizada em posição vertical, para transferir porções de líquido de volume rigorosamente conhecido para outros recipientes, geralmente durante operações de titulação.

Next-generation intelligent body armor requires high anti-impact performance, low weight, flexibility, and integration with multifunctional wearable devices. Shear stiffening gel (SSG), a kind of high-molecular-weight polymer with interesting properties such as dynamic boron-oxygen (B-O) weak crosslinks, nonlinear mec…

Corrosão é a degradação de materiais quando estes são expostos a ambientes reativos (líquidos ou gasosos). Embora o ataque possa ocorrer em metais, semicondutores, isoladores ou polímeros orgânicos, a designação está tradicionalmente associada ao desgaste de metais. Os compostos que resultam de tal degradação são seme…
This research article contains process of RMPA modification into triple band feeler using negative media or metamaterial. The metamaterial structure contains amalgamation of rectangular and circular shapes to form a design which improvise the patch results to a great extent. The centre of interest in this letter is to…
The neutron absorption section of gadolinium atom is very high, so that the K2GdF5 crystals doped with Tb3+ ions have been studied for neutron dosimetry by the thermoluminescence (TL) method. The K2GdF5 crystals doped 2%, 3% and 5% concentrations of Tb3+ ions were synthesized by solid state reaction method. The TL pro…
Degradation of chitosan in swollen state with hydrogen peroxide solution (5% w/v) by γ-irradiation was investigated. Molecular weight (Mw) of irradiated chitosan was determined by gel permeation chromatography (GPC). Fourier transform infrared (FT-IR) and ultraviolet-visible (UV-vis) spectrawere analyzed to study the…
