Abstract In the present study, 5 different consolidants were tested on marble varieties preliminarily subjected to artificial weathering, evaluate their consolidating effectiveness and thermal behavior after consolidation, in terms of residual strain heating–cooling cycles dry wet condition tendency bowing. Treatments based ethyl silicate, with without a coupling agent improve performance calci...

Camptomelic dwarfism or dysplas1a is a rare syndrome in which· short stature is associated with angulation and bowing of the lower limb Long bones, hypoplasia of the facial bones and scapula and various other skeletal and respiratory and nervous system. A 9 day old girl with this syndrome was admitted in our peiatric Department, Loghman Hospital medical center because of Dwarfism and hypotonia....

BACKGROUND Proper limb and component alignments as well as soft tissue balance are vital for the longevity and optimal long-term outcomes of total knee arthroplasty (TKA). This procedure is technically demanding in patients with Ranawat type-II valgus arthritic knees with marked coronal femoral bowing. Computer-assisted surgery (CAS) and intra-articular bone resection with TKA are the treatment...

a r t i c l e i n f o a b s t r a c t Using the first-principles band-structure method, we investigate the p-type doping properties and band structural parameters of the random Ga 1−x In x N 1− y As y quaternary alloys. We show that the Mg Ga substitution is a better choice than Zn Ga to realize the p-type doping because of the lower transition energy level and lower formation energy. The natur...

We report a giant bowing of the spin-orbit splitting energy Delta0 in the dilute GaAs1-xBix alloy for Bi concentrations ranging from 0% to 1.8%. This is the first observation of a large relativistic correction to the host electronic band structure induced by just a few percent of isoelectronic doping in a semiconductor material. It opens up the possibility of tailoring the spin-orbit splitting ...

Plasma etching (or dry etching) is widely used in the fabrication of integrated circuits (IC). Anisotropic features are easily obtained by controlling reactive ion trajectories in plasma. Twisting and bowing are two main issues during high aspect ratio (HAR) feature etching. Twisting is, instead of a feature etching vertically, the feature twists or turns to the side. Mixing damage by ion bomba...
