titania nanotubes (tnt) prepared by anodization of ti foils were used for water splitting in a standalone cell. the concentration polarization between the anode side (1m naoh) and cathode side (0.5 m h2so4) ensured that the water splitting reaction could take place with no external bias and separate h2 and o2 evolution could be achieved. the destruction of tnt structures under 365 nm uv irradia...

recently, two of the authors have introduced the collapse capacity spectrummethodology, which allows the assessment of the collapse capacity of highly inelastic p-deltasensitive regular frame structures without performing non-linear time-history analyses. the mainingredient of this method is the collapse capacity spectrum, which represents the seismic collapsecapacity of an inelastic non-deteri...

fluid invasion from water-based drilling mud (wbdm) into the shale formations causes swelling,high pressure zone near the wellbore wall, and eventually wellbore instability problems duringdrilling operations. for the stability of the wellbore, physical plugging of nanoscale pore throats couldbe considered as a logical approach toward avoiding the fluid invasion into the shale formation. thispap...

results overall, there were 2 (2.7%) mason ii fractures, 21 (28%) mason iii fractures, and 52 (69.3%) mason iv fractures. arbeitsgemeinschaft fur osteosynthesefragen (ao) classification was also determined. of the 85 patients in our study, 75 were available for follow-up. follow-up averaged 41.5 months (range, 4 - 93 months). average scores for the cohort were as follows: morrey, 85.7 (median 9...

background: microsatellite instability (msi) is a mutational signature that is the hallmark of lynch syndrome, and msi testing is a cost-effective method to screen the disease. since there is no enough data about msi status and associated clinicopathologic features of hereditary nonpolyposis colorectal cancer (hnpcc) in iran, our study is a new trial to describe them in center of iran (isfahan)...

instabilities of a thin viscous film flowing down a uniformly heated plane are investigated in this study. the heating generates a surface tension gradient that induces thermocapillary stresses on the free surface. thus, the film is not only influenced by gravity and mean surface tension but also the thermocapillary force is acting on the free surface. moreover, the heat transfer at the free su...

Background. Mechanical relation between the foot and pelvic alignment had been studied in healthy subjects and individuals with other musculoskeletal disorders; however, in chronic ankle instability (CAI), it has not yet been determined. Objectives. To investigate the difference in pelvic torsion (PT) among individuals with CAI and uninjured subjects and correlate PT with perceived ankle insta...

Radiographic instability seemingly enjoys the status of a well-defined clinical syndrome. The concept is widely used, and specific treatments, usually spinal fusion, are routinely performed based on the diagnosis. The minimum standards necessary to establish radiographic instability as a legitimate clinical syndrome have not been established, however. The primary purpose of this study was to de...

Based on a nationally representative sample of 2,017 children age 2-9 years, this study examines variations in "safe, stable, and nurturing" relationships (SSNRs), including several forms of family perpetrated victimization, and documents associations between these factors and child trauma symptoms. Findings show that many children were exposed to multiple forms of victimization within the fami...

Hemodynamic instability often leads to hypoperfusion, which has a significant impact on outcome in both medical and surgical patients. Measures to detect and treat tissue hypoperfusion early by correcting the imbalance between oxygen delivery and consumption is of particular importance. There are several studies targeting different hemodynamic endpoints in order to investigate the effects of go...
