ASTM A 182 F22 steel, used in components subsea for oil extraction, are previously buttered with ductile metal such as Inconel 625, before being welded to steel pipes similar A36 steels. The thermal buttering weld cycle provides the formation of high hardness micro-phases and carbides at interface between Inconel, which when contact hydrogen, originating from cathodic protection applied these e...

Triangulation and histological studies were made of skin ablation depths following skin treatments with a Fotona Dynamis Er:YAG laser system. The following laser handpieces were used in the study: Full beam handpieces R04 and R11; Stamping patterned handpieces PS01, PS02 and PS03; fractionated handpiece FS01 and c) Scanning fractional handpiece F22. The laser fluence (F) was found to be the maj...

Anti-Dopamine-2 receptor (D2R) antibodies have been recently identified in a subgroup of children with autoimmune movement and psychiatric disorders, however the epitope(s) and mechanism of pathogenicity remain unknown. Here we report a major biological role for D2R extracellular N-terminus as a regulator of receptor surface availability, and as a major epitope targeted and impaired in brain au...

Abstract In this paper, a controlled-laboratory experiment is carried out to evaluate the lidar depolarization ratio of freshly emitted soot aggregates in exact backward scattering direction at 180.0°. The performed two wavelengths simultaneously, namely 355 and 532 nm, often used polarimetric remote sensing. are generated from kerosene JET A-1 pool fire laboratory ambient air microscopic image...

Recent years have seen an increase in the use of lignocellulosic materials development bioproduct, biorefinery technologies focused on process integration for production different valuable coproducts order to reduce overall processing cost. In this study, agricultural wastes from rice straw were used co-production bioethanol and xylitol. Where is produced cellulosic fraction xylitol hemicellulo...

We give a two-parameter quantum deformation of the exterior plane and its differential calculus without the use of any R-matrix and relate it to the differential calculus with the R-matrix. We prove that there are two types of solutions of the Yang-Baxter equation whose symmetry group is GLp,q(2). We also give a two-parameter deformation of the fermionic oscillator algebra. Quantum groups are a...

Abstract The present work focusses on development of a safe, inexpensive, and more accessible source for biosynthesis silver nanoparticles. Four different in-house probiotic isolates, i.e., Lactobacillus pentosus S6, plantarum F22, crustorum F11, paraplantarum KM1 isolated from food sources, were used in the current study to check their ability synthesize All probiotic-synthesized nanoparticles...

RESUMO Um adequado procedimento para a soldagem de materiais dissimilares deve prever o amanteigamento do bisel através da técnica dupla camada, modo estabelecer uma barreira térmica capaz minimizar os problemas fragilização junta. A interface nessas soldas é apontada como região mais crítica junta devido à presença fases duras, normalmente encontradas na grosseira zona afetada pelo calor (ZAC)...

If migrants return to their origin countries, two questions arise which are of immediate economic interest for both immigration and emigration country: what determines their optimal migration duration, and what are the activities migrants choose after a return. Little research has been devoted to these two issues. This paper utilises a unique survey data set which records activities of returned...
