BACKGROUND The elliptical (fusiform) excision is a basic tool of cutaneous surgery. OBJECTIVE To assess the design, functionality, ease of construction, and aesthetic outcomes of the ellipse. DESIGN A systematic review of elliptical designs and their site-specific benefits and limitations. In particular, we consider the (1). context of prevailing relaxed skin tension lines and tissue laxity...

This paper analyses security mechanism and authentication, key agreement protocol of 3G system amply, puts forward a amelioration scheme. This scheme assures security communications without credible VLR. This paper analyses ameliorative protocol and resolves the security communications problem between MS and HLR.

The crossed molecular beams reaction of ground state cyano radicals (CN) with diacetylene (HCCCCH) was studied in the laboratory under single collision conditions. Combining the derived center-of-mass translational energy and angular distributions with novel electronic structure calculations, we show that the linear cyanodiacetylene molecule (HCCCCCN) is the sole reaction product. Our study pro...

BACKGROUND Infection is a serious complication of cardiovascular-implantable electronic device implantation and necessitates removal of all hardware for optimal treatment. Strategies for reimplanting hardware after infection vary widely and have not previously been analyzed using a large, multicenter study. METHODS AND RESULTS The MEDIC (Multicenter Electrophysiologic Device Infection Cohort)...

The purpose of this study was to compare outcomes and complications of clavicular hook plate and Kirschner tension band wiring for fixation of unstable lateral clavicle fractures. The surgical outcomes of 92 consecutive patients (mean age, 49.30 ± 15.54 years) with unstable fractures of the lateral clavicle treated using AO clavicle hook plates were compared with those of 24 patients (mean age,...

BACKGROUND The PrePex medical male circumcision (MMC) device is relatively easy to place and remove with some training. PrePex has been evaluated in several countries to assess feasibility and acceptability. However, several studies have reported pain associated with removal. OBJECTIVE To assess safety of PrePex and whether analgesia administered prior to removal reduces pain experienced by p...

this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion w...

in the present study, advanced oxidation treatment, uv/ was applied to decolourisation of acid orange 8 (ao8). the uv radiation was carried out with a 15 w low-pressure mercury lamp. kinetic model for the decolourisation of the dye was developed based on experimental results and known chemical and photochemical reactions. the observed kinetic reaction constant was determined and correlated as a...

in this study; utilizing the elastic matrix ball has higher processing efficiency and better superficial quality than traditionalgrinding. the diversity of elastic abrasive tool characteristics contact with bend surface results in irregular wear abrasion，and abrasive tool machining status gets complicated. there is no theoretical interpretation of parameters affecting the grinding accuracy. bec...
