BACKGROUND Knee and hip arthroplasty constitutes a large percentage of hospital elective surgical procedures. The Blaylock Risk Assessment Screening Score (BRASS) was designed to identify patients in need of discharge planning. The purpose of this study was to evaluate whether the BRASS was associated with length of stay (LOS) in hospital following elective arthroplasty. METHODS We retrospect...

Ectopic eruption of a first permanent molar is a common occurrence in the developing mixed dentition. Proper management is a challenge to the pediatric dentist and is crucial to a healthy occlusion. Non-treatment can result in early loss of the second primary molar, space loss, and impaction of second premolars. Future corrective treatment may be complicated, lengthy, and costly and include: th...

Ag is used as a useful alloying element in brazing filler metals. It clear that the addition of has positive effect on melting temperature, wettability, conductivity and mechanical property For this reason, although very expensive, it still widely many research production. In study, was focused obtaining both high strength cost-effective joints by using metals containing different levels Ag. Me...

In 1933 the method of laminar thermocoagulation of the cerebral cortex was described.' 2 This allows one to destroy, at will, any number of cortical layers, and has the following additional advantages: ( 1 ) the continuity of the cortex is undisturbed, (2) no bleeding occurs, (3) the killed region is strictly confined to the heated area, (4) the cortex immediately outside the killed area is fun...

In passive scattering proton therapy, patient specific collimators (apertures) are used to laterally shape the proton beam, and compensators are employed to distally conform proton dose to the target. Brass is a commonly used material for apertures and recently a hybrid brass/stainless-steel (BR/SST) aperture design has been introduced to reduce treatment cost without clinical flow change. We m...

PURPOSE To analyze the predictive validity and reliability of the Blaylock Risk Assessment Screening Score (BRASS) Index in a large group of patients. METHODS Prospective multicenter observational study was conducted in six Italian hospitals. Data were collected in three phases. FINDINGS Seven hundred eleven patients were recruited. The mean length of hospitalization for low-risk patients w...

The electropolishing behaviour of 73 brass was studied by means of a rotating cylinder electrode (RCE) in a 70 vol % H3PO4 solution at 27 ◦C. Owing to the formation of a blue Cu2+-rich layer on the brass-RCE, an obvious transition peak was detected from kineticto diffusion-controlled dissolution in the anodic polarisation curve. Electropolishing was conducted at the potentials located at the tr...

Gear fabrication in wire electrical discharge machining (WEDM) plays an important role manufacturing industries. This paper describes the analysis and optimization of process parameters for spur gear on brass workpiece (10cmx15cmx6mm) material by EDM process. The experiments were performed using design experiment (DoE) approach removal rate (MRR) was analyzed response surface methodology techni...
