Introduction: Laser tissue soldering is a new technique for repair of various tissues including the skin, liver, articular cartilage and nerves and is a promising alternative to suture. To overcome the problems of thermal damage to surrounding tissues and low laser penetration depth, some exogenous chromophores such as gold nanoshells, a new class of nanoparticles consisting of a dielectric cor...

There has been major interest in Lead-free soldering within the electronics assembly industry for the last several years, and this will continue with the agreement on the language and implementation dates of the WEEE/ROHS legislation in the EU. This paper will focus on several topics critical to the implementation of lead-free soldering. These topics include the impact of Tin-silver-copper as t...

The structural and conducting properties of single-wall carbon nanotubes SWCNs in soldered configuration is obtained using efficient formalisms based on spin-polarized tight-binding formulation incorporating full consideration of s, p, and d basis sets for carbon and metal atoms. The full structural relaxation of the combined SWCN and metal system is found to be essential for realistic characte...

In anticipation of a new era of synchrotron radiation sources based on Energy Recovery Linac techniques we designed, built and tested a short undulator magnet prototype whose features make optimum use of the unique conditions expected in these facilities. The prototype has pure permanent magnet (PPM) structure with 24mm period, 5mm diameter round gap and is 30cm long. In comparison with convent...

This study compared fabr/cation of silver solder joints by dental students using an orthodontic blowpipe .or a Hydroflame ® soldering unit. Fifty-eight students attended a lecture and observed demonstrations of silver solder/ng. Thirty students used a Hydroflame ® to prepare one practice solder joint and two technique solder joints. These students then prepared one practice solder joint and two...

early 40 years of experience with wave soldering N have resulted in processes that routinely produce several thousand, defect-free solder joints per minute. However, the climate of electronics manufacturing has changed significantly over the past 10 to 15 years. Environmental restrictions as well as the high quality of products made offshore has placed new demands and challenges on the electron...

“Sagging” of the palatal cusp upper second molars is a common finding observed during orthodontic treatment which may develop heavy balancing side contacts, have been found to be detrimental harmonious function masticatory system. Various modifications transpalatal arch (TPA) are advocated correct crossbite, but most them will utilize an additional step soldering wire attachment TPA. In this cl...

Introduction: Laser tissue soldering using albumin and indocyanine green dye (ICG) is an effective technique utilized in various surgical procedures. The purpose of this study was to perform laser soldering of rat skin under a feedback control system and compare the results with those obtained using standard sutures. Material and Methods: Skin incisions were made over eight rats’ dorsa, which w...
