A quat-silicone micro-emulsion (particle size <40 nm), an amino-silicone macro-emulsion (110 nm), and an alkyl modified silicone macro-emulsion (740 nm) were used to modify Scots pine (Pinus sylvestris L.) sapwood. Treated and uncoated boards were exposed to natural weathering for one year along with water treated controls according to EN 927-3. The treatment with silicone emulsions did not enh...

A body powered hand prosthesis has been developed with a view to meeting some of the more c o m m o n criticisms made against currently available designs i.e. weight and cosmetic appearance. A n overall weight reduction of about 30 per cent has been achieved and the use of silicone rubber as the cosmetic glove material has resulted in greatly improved cosmesis and stain resistance. The prosthes...

Reworking electronic packages is an integral process related to diagnostics and salvaging valuable materials. It is a meticulous and time-consuming procedure that requires some knowledge of the package material composition to determine compatible cleaning solutions and processes. Silicone adhesives are being used more frequently due to their ability to minimize shear stress during temperature c...

Abstract The main component of Silicone-based heat transfer fluids is modified silicone oil. high and low using temperature silicone-based better than hydrocarbon organic fluids. raising the maximum means that it can obtain higher steam in process system, power generation efficiency turbine will be improved remarkably if are used parabolic through solar system. It also increase a thermal plant,...

there are many studies about epidural fibrosis after surgical manipulation of the spine. we have studied formation of the post laminectomy epidural fibrosis after application of two materials (silicone and teflon) in this report. this expriment is on two groups of rats. two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces silicone was u...

STATEMENT OF PROBLEM Speech bulbs and palatal lift prostheses are used to improve oral-nasal balance in speakers with hypernasality resulting from velopharyngeal dysfunction. Fabricating such speech prostheses is often a protracted process, and the nasopharyngeal impression can be uncomfortable for the client. PURPOSE The purpose of this study was to develop and test a modular palatal lift pr...

38S Since the first breast implants were introduced in the early 1960s,1 there have been various design improvements to the round implant, which had been the only shape commercially available for over 50 years. As breast implant surgery became more popular across a larger demographic and patients requested a more “natural” shape, the need for an anatomically shaped silicone implant became appar...

PURPOSE To describe the CT and MR characteristics of intraocular silicone oil (polydimethylsiloxane), which is used with increasing frequency to treat complicated retinal detachments. METHODS CT was performed on a silicone oil/water phantom and on a patient with retinal detachments secondary to cytomegalovirus retinitis, treated by bilateral intraocular injections of silicone oil. CT appearan...

BACKGROUND Combined with vitreoretinal surgery, silicone oil injection has become a standard technique and improves the prognosis of complex retinal detachment. As silicone oil leads to long term complications, removal of silicone oil from the eye is recommended. To evaluate the outcome after silicone oil removal, retinal redetachment, visual acuity, and complications were analysed. METHODS T...
