hoosing a pressure transducer for a precision measurement system (one where the total error budget is less than 1 percent) has traditionally not been a simple matter of going to a catalogue and quickly finding a device to fit the needs of the application. The task of selection was complicated by many factors, among them specifications that were often deceptive, and hidden error sources both in ...

In this study we report antibacterial modification of Kirschner wires (K-wires) with polyluteolin (PL) toward methicillin-resistant Staphylococcus aureus (MRSA). K-wires were modified by immersing them in the luteolin-containing aqueous solution for 24 h. Characterizations using scanning electron microscopy and electrochemical methods confirmed the presence of the PL coatings on the K-wires. Th...

While the cost of living is going up, there a growing focus to involve technology lower those prices. With this in mind Smart Home research allows user build and maintain house that smart enough keep energy levels down while providing more automated applications. This concept can be suitably included make our smarter, saver, efficient automated. focuses on building save, system by using interne...

purpose: according to frequent needs to gastric decompression by nasogastric tube insertion during laparoscopic cholecystectomy, the current comparative study was accomplished through single blind clinical trial considering both the presence and the absence of guide wire insertion. materials and methods: twenty patients were selected for elective surgery of laparoscopic cholecystectomywith gene...

The purpose of this study was to evaluate mechanical properties of the orthodontic wires according to heat treatment environments and cooling methods. Four types of wires were heat-treated in air, argon and vacuum at 500◦C, for 6 min, and were then either cooled in the furnace or a water bath. Increases in microhardness, maximal strength, yield strength and Young’s modulus of the orthodontic wi...

Abstract The evolution of grain size and component mechanical behaviour are fundamental aspects to analyse control when manufacturing processes considered. In this context, severe plastic deformation (SPD) processes, in which a high shear strain is imposed on the material, recognized as main techniques achieve microstructural changes material strengthening by recrystallization, attracting both ...

We address the kinematics of the redundant N − 1 wire-driven parallel robot, i.e. a robot with N > 3 wires connected at the same point on the platform. The redundancy allows one to increase the workspace size. But we show, both theoretically and experimentally that if the wires are not elastic, then the redundancy cannot be used to control the wire tensions. Indeed we show that whatever are the...

Thick bonding wires are used in modern power modules as connectors between integrated circuits, carrying current from one circuit to another. They experience high values of current, which generates heat through Joule heating and can lead to various failure mechanisms. Typically used wire materials in industry are aluminum (Al), copper (Cu), and intermetallic compounds of Cu-Al. They are broadly...

The aim of this study was to find out whether number and position of K-wires influence the stability of distal radius fractures treated by percutaneous wire fixation. Patients who underwent K-wire fixation for unstable fractures of the distal radius over a period of three years were included in this retrospective study. Radiographs taken immediately after the procedure and radiographs taken aft...
