OBJECTIVES It is currently debated whether patients with residual viraemia are at higher risk of virological failure than those attaining <1 HIV RNA copy/mL. We therefore investigated the effect of residual viraemia on virological rebound. METHODS We used a prospective, non-interventional, single-centre, study. This analysis was based on HIV-infected patients with two consecutive HIV RNA vira...

When particles strike a surface they can either rebound or deposit on the surface. If particles rebound on human facial skin they can be re-entrained into the airflow and subsequently inhaled, increasing aspiration efficiency estimates. To accurately model particle bounce on human facial skin and the effects on aspiration efficiency estimates, a realistic estimate of human facial skin coefficie...

Ocular sympathetic nerves were stimulated chronically in awake rabbits using electrodes unilaterally implanted on the cervical sympathetic trunk. IOP was measured by pneumatonometry and aqueous inflow was measured by fluorophotometry. In each animal, continuous trains of 1 msec pulses were delivered by means of a portable electrical stimulator. Experiments were spaced by 1 week recovery periods...

AIM To evaluate the influence of age on the measurements and relationships among central and peripheral intraocular pressure (IOP) readings taken with a rebound tonometer. METHODS The IOPs were measured using the ICare rebound tonometer on the right eyes of 217 patients (88 men and 129 women) aged 18-85 years (mean 45.9 (SD 19.8) years), at the centre and at 2 mm from the nasal and temporal l...

Vibratory sensation thresholds of ten fingertips of each person were measured by each of the three frequencies in groups using three kinds of vibrating tools and the control groups. The subject groups were using leg-drill (n=37), chipping-hammer (n=25) and chain-saw (n=19). The control groups were engaged in desk work or outdoor work in a bureau of forest management (n=24), a local forest offic...

Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.

This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...

Abstract The slope instability was one of the common problems along road that connects Gutane Migiru town to Fincha sugar factory, Western Ethiopia. effect problem intense mostly; during rainy season, triggers different modes rock failure. As a result, frequently damaged and blocked by failed in turn hinders traffic activities. Thus, this study aimed at stability analyses critical sections usin...

These values are plotted in Figure 1. Dots indicate magnitudes derived from the 4-inch camera plates. Open circles represent the magnitudes obtained with the 18-inch Schmidt telescope. This instrument has a focal ratio 1:2. Under the best conditions it reaches a limiting magnitude m = 17 with an exposure time of ten minutes on ordinary non-color-sensitive portrait films. For the use of the 18-i...
