background:  the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   methods:  this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...

This paper presented a novel approach to the multipulse voltage converters (VC), especially voltage source inverters (VSI) and matric converters (MC) based on several typical identical modules connected in parallel using Inductive Current Splitters/Mergers. Such arrangements resulting in lower voltage distortions at extremely low switching frequency. Proposed new arrangements was validated by s...

Pseudomonas putida strain mt-2 unsaturated biofilm formation proceeds through three distinct developmental phases, culminating in the formation of a microcolony. The form and severity of reduced water availability alter cell morphology, which influences microcolony size and ultrastructure. The dehydration (matric stress) treatments resulted in biofilms comprised of smaller cells, but they were ...

Shallow landslides triggered by heavy rainfalls have caused casualties and economic losses to domestic infrastructures industries worldwide. Rainfall mainly reduces the soil matric suction shear resistance, resulting in shallow landslides. Vegetation is an eco-friendly cost-effective method for stabilizing slopes prone This research aims investigate hydrological mechanical effects of vegetation...

Control of water and air in the root zone of plants remains a challenge in the microgravity environment of space. Due to limited flight opportunities, research aimed at resolving microgravity porous media fluid dynamics must often be conducted on Earth. The NASA KC-135 reduced gravity flight program offers an opportunity for Earth-based researchers to study physical processes in a variable grav...
