Here we describe a very efficient method to produce well-defined amphiphilic gold nanoparticles (Au NPs) with an equal number of hydrophobic and hydrophilic arms which are distributed along the surface of a 2-nm gold core in an alternating fashion. The strategy involves direct coupling of V-shaped block copolymer amphiphile 2 with a carboxylic group at its junction point to mercaptophenol-termi...

The positioning of wireless nodes in indoor Wireless Local Area Network (WLAN) using Received Signal Strength Indication (RSSI) has become an attractive low cost localization solution. The location accuracy of RSSI based algorithms is dependent on node placement topology. The localization performance analysis reported for nodes arranged in V-shaped linear configuration. The uniqueness of this w...

Although dental implants have been successfully used for the rehabilitation of fully edentulous and partially edentulous patients, patient’s various conditions constrict the application of implant, or make dental treatment using dental implants very complex and difficult. Implantsupported cantilever prostheses represent that conditions. Becker and Kaiser insisted that alignment problems, extens...

This paper presents a case study of geotechnical design of bridge foundations and approaches in hilly granite formation in northern New South Wales of Australia. Firstly, the geological formation and existing cut slope conditions which have high risks of rock fall will be described. The bridge has three spans to be constructed using balanced cantilever method with a middle span of 150 m. After ...

Due to their small size, low weight, low cost and low energy consumption, MEMS (Micro Electro-Mechanical Systems) accelerometers have achieved great commercial success in recent decades. The objective of this paper is to find the optimum design for a typical MEMS accelerometer, which satisfies a set of given constraints. Due to the complex nature of the problem, a gravitational search algorithm...

Micromechanical cantilevers show great potential as highly sensitive biochemical sensors. Cantilever-based sensing involves the transduction of a biomolecular interaction to a measurable mechanical change in the cantilever resulting from induced surface stresses added mass. In surface stress sensing applications, one side of the cantilever beam is rendered sensitive to a specific target molecul...

S.Z. cantilevers are made using a simple one-mask fabrication process with.characterization of a cantilever-type MEMS chemical sensor for detection of chemicals. MEMS has been with the advancement of cantilever-type sensors.sensor. The mechanical structure is a cantilever, having its own resonant frequency. MEMS cantilevers can be as thin as a few nanometers with lengths.Cantilever-based Sensor...

a 14 year old boy suffering from marked penoscrotal lymphedema is reported. reduction scrotoplasty was done and the neoscrotum was made by combining the anterior suprapubic and posterior scrotal v-shaped flaps. a split-thickness skin graft from the thigh was placed over the denuded penis. no complication was encountered and the cosmetic result was satisfactory
