The title compound, [Cu 2 (C 5 H 6 O 4 ) 11 10 N O)] n , contains square-pyramidally coordinated Cu II ions linked by anti-gauche conformation glutarate (glu) ligands into ] di-periodic coordination polymer layers with embedded (OCO) paddlewheel clusters. In turn, the layer motifs are connected 1,3-di(pyridin-3-yl)urea (3-dpu) linkers to form a (3-dpu)] tri-periodic network. Treating clusters a...

A common problem with artificial hip replacements is increased wear of the material in contact. Materials that are contact result pressure caused by patient's daily activities so it triggers wear. This study adopts a finite element method (FEM) to predict joint, studying behavior joint prosthesis has clearance under certain load. The aim this was observe as function and body weight. modeling us...

The Northrop Grumman Cordless Communications System (CCS) is a state-of-the-art, wireless communications system targeted for tomorrow’s armored battlefield. Through a single, hand-held or body-mounted Personal Communications Unit (PCU), the CCS provides the soldier with access to a digital, fullduplex wireless intercom, as well as the capability to simultaneously communicate over a point-to-poi...

Jakarta as the capital city of Indonesia is center economy, culture, and politics. Jenderal Sudirman street always crowded with passing vehicles, traffic snarls up everyday. The causes these jam an increase number vehicles cause a change in behavior. Theoretically there fudamental relationship between flow, speed, & density, so purpose research are to analyze evaluate performance capacity v...

The fuel cells are considered as one of the most promising devices for standalone/grid connected distributed generations (DGs) due to its cleanliness, modularity and higher potential capability. The barriers in the widespread use of fuel cells are their slow response for sudden load changes and higher installation cost. In this paper a simulation study of dynamic behavior of Nexa 1.2kW PEM fuel...

An acid-stable Zn(II) complex formulated as Zn2(HL)2(SO4)·H2O (1) and an acid-unstable complex formulated as Zn2L2·12H2O (2) were hydro(solvo)thermally synthesized and structurally characterized by single-crystal X-ray diffraction. Complex 1 features a uninodal 6-connected 2-fold interpenetrating three-dimensional (3D) dense architecture with {4(12)·6(3)}-pcu topology, and complex 2 exhibits a ...

Métodos de estimativas como o Pontos por Casos de Uso (PCU) calibram o tamanho do software baseado em características técnicas e ambientais associadas aos projetos e às equipes de desenvolvimento. Este artigo analisa os resultados de uma pesquisa realizada com profissionais da área de software, utilizando o método Processo Analítico Hierárquico (AHP), sobre a relevância de cada uma das caracter...

This report describes the first human retrieval of a polycarbonate-urethane (PCU) acetabular cup implanted for 10.5 months that was revised for pain of unknown origin. By using a micro-CT analysis, the articulating surface was determined to have a wear rate of less than 1.4 mm3 per year. An analysis of the synovial fluid retrieved at the time of revision found an average particle size of 1 mum ...

Fabrication of a cysteamine (CA) self-assembled monolayer (SAM) modified gold electrode insitu functionalized with L-Lysine (Lys) is presented and described. The fabricated electrode was used for highly selective and sensitive accumulation and the determination of copper ions (Cu) in a nanomolar concentration. Techniques like cyclic voltammetry (CV) and electrochemical impedance spectroscopy (E...
