Influência do formato do cordão de solda na vida em fadiga de rodas de caminhão utilizando o processo de soldagem Tandem-MIG
\n Neste trabalho foram soldadas 4 amostras de rodas para veículos comerciais pelo processo de soldagem Tandem-MIG. Para cada amostra foram utilizados parâmetros de soldagem diferentes de modo a se obter formatos de cordão de solda distintos. O objetivo do trabalho foi avaliar a influência desses formatos de cordão de…
Uji sitotoksisitas ekstrak daun Widuri (Calotropis gigantea. l) terhadap larva udang Artemia Salina Leach dan identifikasi golongan senyawa aktifnya
INDONESIA: \n \nTanaman widuri (Calotropis gigantea L.) merupakan tanaman liar yang banyak tumbuh di Indonesia dan dapat dimanfaatkan sebagai obat herbal. Al Qur’an surat Ali Imron ayat 190-191 menjelaskan tentang perintah Allah kepada makhluknya untuk memikirkan dan mencari manfaat dari berbagai macam tumbuhan yang t…
Ambient Pressure Structural Quantum Critical Point in (Ca$_x$Sr$_{1-x}$)$_3$Rh$_4$Sn$_{13}$
The quasi-skutterudite superconductor Sr$_3$Rh$_4$Sn$_{13}$ features a pronounced anomaly in electrical resistivity at $T^*\sim$138 K. We show that the anomaly is caused by a second-order structural transition, which can be tuned to 0 K by applying physical pressure and chemical pressure via the substitution of Ca for…
Nanoparticle Adsorption and Crossing of Fluid Interfaces
Solid micron- and nano- particles have been extensively used to stabilize dispersions such Pickering emulsions and particle-stabilized foams. In many cases, particle's adsorption onto the fluid interfaces represents a limiting step for the stability of the dispersion since adsorption can be very slow or even hindered…

Laskentamenetelmien vaikutus magneettikuvauksen relaksaatioaikoihin maksan ja sydämen rautapitoisuustutkimuksissa
Eräiden sairauksien sekä jatkuvien verensiirtojen seurauksena potilailla saattaa esiintyä poikkeuksellista raudan kertymistä elimistöön. Raudan kertyminen elinten peruskudoksiin voi aiheuttaa rautaperäisiä pysyviä kudosvaurioita. \n\nMagneettikuvauksen (MK) gradienttimonikaikusekvensseistä saaduista kaikukuvista laske…

Measuring viscosity on the nanoscale using fluorescent molecular rotors
M environment-sensitive probes offer the opportunity to chart physical and structural alterations on the nanoscale. Many areas of science have benefited from the unique information afforded by probes located within inaccessible spaces, which could not be collected by conventional techniques. Response to pH, polarity,…
Effective therapy for prostate cancers
I this work, the author has developed the first ultra-effective photothermal agents for prostate cancer-targeted therapy. The newly synthesized probe was found to be intensely and specifically accumulated into all prostate cancer cells without any impact on the cell viability, resulting in tremendously efficient targe…
Phase relations in a portion of the system Sc{sub 2}O{sub 3}-ZrO{sub 2}
From American Ceramic Society Basic Science Division Meeting, Washington, D. C., Oct. 1963. X-ray diffraction, differential thermal analysis, quench techniques, electrical conductivity measurements, and microscopic examination were used to determine the phase relations in the ZrO/sub 2/-rich portion of the Sc/sub 2/O/…
Erosive wear of polymer composite materials and its correlation with high strain rate mechanical properties
Erosive wear phenomena have been studied for more than half a century and it is well known that high-speed impacts generate very high strain rates. However, the research so far have used quasi-static data to correlate the erosive wear with material properties. There is need for generating high rate materials propertie…

Self healing organic coatings on aluminium alloy
Aluminium and its alloys represent one of the most cost-effective production class of materials because of their high specific strength-to-weight ratio. However, they can be seriously limited by corrosion attack, especially in aqueous electrolytes containing chlorides, which leads to huge economic losses. Therefore, t…
Experimental substantiation of the use of materials «КLIPDENT» «BIOPLAST-DENT» at the substitution of bone defects after traumatic removal of teeth
The effect of osteoplastic materials of various fractions «Klipdent», «Bioplast-dent» on the speed and quality of processes osteoreparation of bone defect resulting from traumatic removal of teeth of the lower jaw was studied. The authors note morphologically confirmed an increase in the intensity of the processes of…
(Bio)Chemical Tailoring of Biogenic 3-D Nanopatterned Templates with Energy-Relevant Functionalities
The overall aim of this research has been to obtain fundamental understanding of (bio)chemical methodologies that will enable utilization of the unique 3-D nanopatterned architectures naturally produced by diatoms for the syntheses of advanced functional materials attractive for applications in energy harvesting/conve…
Laser Chemical Processing of n-Type Emitters for Solid-Phase Crystallized Polysilicon Thin-Film Solar Cells
We report on the application of laser chemical processing (LCP) to fabricate n-type emitters for polysilicon thin-film solar cells on glass. Sheet resistance values of 2-5 kΩ/□ with a peak phosphorus doping concentration in the range 8 × 1018-1 × 1019cm-3at a shallow doping depth of less than 350 nm are achieved. Afte…
Image-based Cohesive Element Modelling of Low Temperature Crack Propagation in Alloy 82 Weld Metal
Exposure of Alloy 82 welds to hydrogen containing, de-oxygenated aqueous environments at temperatures below 150°C can result in reduction of fracture toughness by up to an order of magnitude. Associated with this reduction is a change in fracture mechanism from ductile to brittle intergranular, commonly termed Low Tem…
