BACKGROUND Patch testing is mandatory for diagnosing contact dermatitis. It is, however, crucial that patients understand and remember the result of the test. OBJECTIVES The aim of our study was to evaluate the impact of patch testing with respect to patients' ability to remember patch test results and the results of natural rubber latex protein allergy after 2 years. METHODS One hundred an...

T he advantages of using a rubber dam are well-known when performing operative and endodontic procedures. These benefits include the following: disolation of the operating field to keep it dry and clean; dimproved access and visibility; dpotentially improved properties of dental materials; dprotection of the patient and dentist; dimproved operating efficiency. 1 Preparing teeth for indirect res...

In order to fully explore the influence of different pressure methods on growth characteristics buckwheat, a test device with adjustable press force, and easy replace wheel was designed. Using dry matter quality buckwheat roots, stems, leaves at seedling stage, plant height, number main stem nodes, branches, grain per plant, weight yield as evaluation indexes, single factor force carried out, t...

Wheel defects on trains, such as flat wheels and out-of-roundness, inevitably jeopardize the safety of railway operations. Regular visual inspection and checking by experienced workers are the commonly adopted practice to identify wheel defects. However, the defects may not be spotted in time. Therefore, an automatic, remote-sensing, reliable, and accurate monitoring system for wheel condition ...

Rubber-steel-layered structures are used in many engineering applications. Laminated rubber-steel bearing, as a type of seismic isolation device, is one of the most important applications of the rubber-steel-layered structures. Interfacial debonding in rubber-steel-layered structures is a typical failure mode, which can severely reduce their load-bearing capacity. In this paper, the authors dev...

The test in the production of microfluidic devices dedicated to medical applications poses several challenges terms contamination, reliability, and cost. present article describes Design-for-Testability approach used make an insulin MEMS micropump that can be fully tested a few seconds. Each key functional parameter positive displacement with check valves is described together detailed pneumati...

Different alley flooring systems have been found to influence claw health and locomotion among dairy cows in cubicle barns. The ability to keep the alley floors clean and dry is part of this. It is, however, challenging to keep the alleys clean at all time. Different cleaning regimes are used, and barns are equipped with a diversity of scrapers and alley surfaces. Scrapers are earlier found to ...

INTRODUCTION There is evidence that increased ambient pressure causes an increase in postural sway. This article documents postural sway at pressures not previously studied and discusses possible mechanisms. METHODS Eight subjects participated in a dry chamber dive to 240 msw (2.5 MPa) saturation pressure. Two subjects were excluded due to unilateral caloric weakness before the dive. Postural...
