A reunião anual de 2015 da Rede Global Biodiversity Heritage Library será realizada no Brasil e abordará o estado de desenvolvimento da Biodiversity Heritage Library (BHL) e sistemas de informação em Biodiversidade.
Organizada pelos Programas SciELO e BIOTA da FAPESP, a reunião está dirigida para pesquisadores e profissionais relacionados com biodiversidade e informação científica. O programa científico contará com autoridades e especialistas nacionais e internacionais.
A Rede Global da BHL (gBHL) conta com a participação da África do Sul, Austrália, Brasil, China, Egito, Estados Unidos e Europa. A BHL trabalha de forma colaborativa em prol do acesso aberto à literatura em biodiversidade como parte da comunidade de biodiversidade global.
A Systematic Study on Composition of Low Viscosity Automotive Lube Oils with ...IJERA Editor
In this work the performance of three commercial lube oils and two base oils of different viscosities, composition have been studied for their tribo performance using four ball tribo tester as per ASTM D 4172D and IP 239 and at the end of the test run the steel ball surfaces have been examined under scanning electron microscope (SEM) to assess the wear deformities. The tribo-performance results have been co-related with the physico-chemical properties along with quantity and type of the molecules present in these oils by proton nuclear magnetic resonance (NMR) studies. It has been observed that the lubricant with higher viscosity, higher aromatic molecules containing CH₂ chains shows lower friction and wear behavior whereas the increasing napthenic type molecules have reverse effect which is evident from the results.

Plasma Transferred Arc surfacing is a kind of Plasma Transferred Arc Welding process. Plasma Transferred Arc surfacing (PTA) is increasingly used in applications where enhancement of wear, corrosion and heat resistance of materials surface is required. The shape of weld bead geometry affected by the PTA Welding process parameters is an indication of the quality of the weld. In this paper the analysis and optimization of weld bead parameters, during deposition of a Nickel based alloy Colmonoy on stainless steel plate by plasma transferred arc surfacing, are made and values of process parameters to produce optimal weld bead geometry are estimated. The experiments are conducted based on a five input process parameters and mathematical models are developed using multiple regression technique. The direct effects of input process parameters on weld bead geometry are discussed using graphs. Finally, optimization of the weld bead parameters, that is minimization of penetration and maximization of reinforcement and weld bead width, are made with a view to economize the input process parameters to achieve the desirable welding joint.

Corrosion Behaviour of Titanium Anodized Film in Different Corrosive Environm...IJERA Editor
Anodizing is an electrochemical process in which thickness of the natural oxide layer is increased and converted it into a decorative, durable, corrosion-resistant film. Titanium is used as a biocompatible material in human implants due to its excellent corrosion and wears resistance. Stable, continuous, highly adherent, and protective oxide films can be developed on titanium using various acid or alkaline baths. Anodizing of titanium generates a spectrum of different color without use of dyes. This spectrum of color dependent on the thickness of the oxide, voltage ranges, interference of light reflecting off the oxide surface and reflecting off the underlying metal surface. The anodized film of Titanium is mainly consists of TiO2 or mixtures of TiO2 & Ti2O3 etc. In the present work, Pure Titanium plate has been anodized using bath of Chromic Acid at different voltage range. The anodized film is characterized by visual observation, SEM & EDAX analysis & A.C Impedance Spectroscopy, while the corrosion studies were performed using Potentiodynamic studies were performed in 3.5% NaCl & 0.1N H2SO4. The Results show that the anodized film of Titanium show different spectrum of colors from Brown-Violet-Tea or Peacock. SEM & EDAX analyses show that the anodized film of Titanium is mainly made up of TiO2 and Ti2O3. Potentiodynamic study implies that the film developed on Titanium using the bath of Chromic Acid exhibits good corrosion resistance. The A.C. Impedance study shows that the film is more compact, adherent and more uniform in chromic acid bath.
