BACKGROUND Despite the firmly established occupational risk of exposure to X-rays, they are used extensively in spine surgeries. Shielding by lead aprons is the most common protective practice. We quantified the level of their radiation blocking ability in a real-life setting. METHODS Single-center, prospective, randomized study of adult patients with degenerative lumbar disorders, scheduled ...

A series of experiments was conducted to investigate the erosion behaviors of the noncohesive sediments downstream of smooth and rough aprons. A total of 33 tests were carried out with five different roughness conditions (k =0, 1, 1.85, 3.35 and 5mm) in a flume 0.5m wide, 0.6m deep and 9m long. For each run, s measurements were taken of the scour-hole profiles at the asymptotic or equilibrium s...

In the process of the optimum design of aprons, solutions should be found for problems and such issues as the optimum area and dimensions of the apron, including the passenger and the cargo the number and dimensions of the gates on the basis of different types of aircraft parking configuration aircraft simulation and arrangement in different time periods of the given day at the airport. In this...

The purpose of this paper is to develop a lightweight apron that will be used for shielding low intensity radiation in medical imaging radiography room and to apply it to a custom-made effective shielding. The quality of existing aprons made for protecting our bodies from direct radiation are improved so that they are suitable for scattered X-rays. Textiles that prevent bodies from radiation ar...

The forces exerted on fibres during drafting in the zone with upper and bottom aprons of Ring Frame significantly impact yarn quality. Aprons are crucial manipulating by facilitating movement directing them toward primary area. From these two aprons, apron's tension is changed changing spring bar groove hole positions. There no scope for such settings case top aprons. This research aims to achi...

This study examined the hypothesis that the wearing of plastic aprons during direct patient contact would reduce significantly the number of bacteria carried on nurses' uniforms, and therefore reduce the probability of the transmission of nosocomial infections. Current nursing practices and overall bacterial uniform contamination levels were investigated, as well as the effects of the wearing o...

OBJECTIVE To analyze the direct cost of reusable and disposable aprons in a public teaching hospital. METHOD Cross-sectional study of quantitative approach, focusing on the direct cost of reusable and disposable aprons at a teaching hospital in northern Paraná. The study population consisted of secondary data collected in reports of the cost of services, laundry, materials and supplies divisi...
