Seven patients with macular hole retinal detachment were treated by intravitreal gas injection with or without release of subretinal fluid. Macular buckling, diathermy, cryopexy, or vitrectomy were not used. The patients were placed prone for eight hours a day until the gas had absorbed. In five of the seven patients the retina became reattached within three days and remained reattached with fo...

Radiometric measurements of the microwave emissivity of foam were conducted in May 2000 at the Naval Research Laboratory’s Chesapeake Bay Detachment using radiometers operating at 10.8 and 36.5 GHz. Horizontal and vertical polarization measurements were made at 36.5 GHz; horizontal, vertical, +45, 45, left circular, and right circular polarization measurements were obtained at 10.8 GHz. Surface...

Detachment from work has been proposed as an important non-work experience helping employees to recover from work demands. This meta-analysis (86 publications, k = 91 independent study samples, N = 38,124 employees) examined core antecedents and outcomes of detachment in employee samples. With regard to outcomes, results indicated average positive correlations between detachment and self-report...

Computer simulations of bubble oscillations in water have revealed that characteristics of bubbles depend on types of sonochemical reactors. When the acoustic amplitude is large at 20 kHz, the bubble content when a bubble collapses is mostly water vapor and the temperature inside a bubble at the collapse is relatively low. On the other hand, when the acoustic amplitude is relatively low, the bu...

This study aims at investigating the role of bubbles passage to prevent biofouling in thin-gap bubble column photobioreactors (PBRs) where biomass concentration is important and reactor thickness low. Different types gas sparging are tested a square channel with cross-section 4x4 mm2 mimicking PBR. Firstly, it shown that very difficult detach biofilm once has adhered wall: only bubbling conditi...

The bubble pressure tensiometer BPA-1P is a new development by SINTERFACE based on more than 10 years of experience in bubble pressure techniques, for example the MPT1 and MPT2 sold by LAUDA. Many new instrumental details have been published recently, such as the determination of bubble time characteristics, the optimisation of the aerodynamic system, as well as the options to reach extremely s...

Lorenz curves of bubble size distributions and their Gini coefficients characterize demixing processes. Through a systematic size classification, bubble size histograms are generated and investigated concerning their statistical entropy. It turns out that the temporal development of the entropy is preserved although characteristics of the histograms like number of size classes and modality are ...
