The purpose of the study was to assess the validity and inter-bike reliability of 10 Wattbike cycle ergometers, and to assess the test-retest reliability of one Wattbike. Power outputs from 100 to 1000 W were applied using a motorised calibration rig (LODE) at cadences of 70, 90, 110 and 130 rev · min-1, which created nineteen different intensities for comparison. Significant relationships (P <...

OBJECTIVE The aim of this in vitro study was to investigate the antibacterial depth effect of continuous wave laser irradiation with a wavelength of 980 nm in the root canal wall dentin of bovine teeth. BACKGROUND DATA The long-term success of an endodontic therapy often fails due to remaining bacteria in the root canal or dentin tubules, which cannot be sufficiently eliminated through the cl...

Background: Conventional T2W imaging alone has a poor sensitivity for prostate cancer detection. This study therefore evaluated combined T2-W and diffusion weighted (DW)-MRI vs. T2-W MRI alone for identifying tumour in patients with prostate cancer. Material and Methods: 54 consecutive patients with prostate cancer (46 Stage 1 and 2, 8 stage 3) and sextant biopsies within the previous 3 months ...

A revision of the shore-fly genus Hydrochasma Hendel. The species of the genus Hydrochasma Hendel are revised, including 27 new species (type locality in parenthesis): H. andeum (Ecuador. Guayas: Boliche (02°07.7'S, 79°35.5'W)), H. annae (United States. Utah. Grand: Swasey Beach (15.3 km N Green River; 39°07'N, 110°06.6'W; Green River; 1255 m)), H. capsum (Ecuador. Orellana: RíoTiputini (0°38.2...

SAPO-11 is synthesized from silicoaluminophosphate in the presence of di-n-propylamine as a template. The results show that sample obtained has good crystallinity, 396m2/g BET surface area, and 0.35 cm3/g pore volume. hydroisomerization activity (0.25)Pt (1)Zr (0.5)W/SAPO-11 catalyst was determined using n-decane base oil. All experiments were achieved at fixed bed plug flow reactor temperature...

We report here on the manufacturing methods for emulsifier-free (EF-) oil-in-water (O/W) emulsions, in which oil and water were mechanically mixed absence of any emulsifiers such as surfactants. A commercially available bath-type ultrasonic cleaner (Bath-US; 42 kHz, 26 W) did not disperse dodecane (DD) completely even by treatment 15 min, average diameter DD droplets EF-dodecane-in-water (DD/W)...

The interaction between a rigid–flexible system and ambient fluid was simulated numerically at Re = 300 by the immersed boundary method. consists of stationary rigid plate upstream closed flexible filament downstream. For different lengths, four typical regimes for motions were observed. As length increases, successively experiences plate-like (P) mode, cylinder-like (C) slender-shape (S) mode ...

Two manganese ores with different iron content were investigated as oxygen carriers for chemical looping conversion of simulated biomass volatiles. The aim was to study the performance regards combustion and potential use chemical-looping gasification wood-based biomass. studied in a 300 W reactor system circulation between fluidized air fuel reactors. temperature 850–900 °C flow rates 0.6–3 Lm...

Polystyrene resins with varied particle sizes (35 to 350-600 microm) and pore diameters (300-1000 A) were employed to study the effects of immobilization resin particle size and pore diameter on Candida antarctica Lipase B (CALB) loading, distribution within resins, fraction of active sites, and catalytic properties for polyester synthesis. CALB adsorbed rapidly (saturation time </= 4 min) for ...
