Di alam ini terdapat berbagai radionuklida alam. Secara kuantitas, yang paling banyak keberadaannya adalah kalium-40, nuklida deret uranium, dan nuklida deret thorium. Pada penelitian ini akan dilakukan penentuan radioaktivitas gamma tanah permukaan dimana data yang diambil dimulai dari tanah permukaan sampai dengan t…
This research was conducted to study the use of artificial pozzolanic material (portlandpozzolana cement or PPC) and natural pozzolanic material (fly ash) to improve quality of strontium liquid waste cementation in saline environment during nuclear waste immobilization process. The portland cement was mixed with 10 v/…
The gas-pump units blades profile geometry changing influence estimation on the character of one’s vibration method has been designed. The reasons of axe compressor blades geometry changing have been described, the method of blade profile mathematical formalization has been selected. To interpolate the blades profile…
Lithium-ion batteries are leading the path for the power sources for various portable applications, such as laptops and cellular phones, which is due to their relatively high energy density, stable and long cycle life. However, the cost, safety and toxicity issues are restricting the wider application of early generat…
A preparação de compósitos de polímeros com cargas e/ou fibras tem sido um meio de obter novos materiais e de melhorar o desempenho dos materiais poliméricos. As cargas metálicas de quasicristais de AlCuFe, surgiram com grande potencial para uso como reforço em compósitos poliméricos, devido suas propriedades como ele…
The objective of the present study is to apply the micro-CT technique to assess recent microbialite samples from a hypersaline coastal lagoon in the Rio de Janeiro State. The study comprises structural assessment, mineralogical characterization and porosity distribution of each sample. Micro-CT is increasingly present…

In nearly all cases within the seismic data processing industry, 3D Prestack Depth Migration (PSDM) of surface land and marine seismic data is preceded in the processing flow by time domain imaging steps. The time-domain steps include iterative NMO velocity analysis, residual statics and often 3D Prestack Time Migrati…
Dialkylstannylene acetals are tin-containing species employed extensively as intermediates to facilitate high-yielding and regioselective monosubstitution reactions of diols or polyols with various electrophiles, which is an important application of organotin compounds in organic synthesis. Although an abundance of ex…
We investigate numerically the modification of surface-plasmon assisted optical force on a gold nanorod pair by incorporating dielectric interlayer. The frequency dependent electromagnetic forces are obtained through full-vectorial solution of Maxwell equations with a finite element solver. We obtain the common and re…
This poster summarize the firsts results of the PhD project started on October 2012 about the catalytic purification of biogas. The aim of this project consists in the development of Ni/Al2O3 catalyst in order to reform the tars present in the outlet gas of biomass gasifier. In order to obtain catalysts with high perf…
In order to obtain a newly room temperature sintering conductive ink that has great potential applications in printed electronics, especially for some temperature-sensitive substrate, the silver nanoparticles with dodecylamine as the protective agent (Ag/DDA) were prepared, and the effects of protective agent on the i…
Normal 0 false false false Isoniazid (INH) resistance in M ycobacterium tuberculosis is commonly associated with mutations in katG encoding catalase - peroxidase . A clinical isolate of M. tuberculosis L21 exhibits isoniazid resistant phenotype. A 2.2 kb DNA fragment of katG gene from the L21 isolate had been cloned a…
