Annealing study and thermal investigation on bismuth sulfide thin films prepared by chemical bath deposition in basic medium
This is a post-peer-review, pre-copyedit version of an article published in Applied Physics A 124.2 (2018): 166. The final authenticated version is available online at: http://doi.org/10.1007/s00339-018-1584-7Bismuth sulfide thin films were prepared by chemical bath deposition using thiourea as sulfide ion source in basic medium. First, the effects of both the deposition parameters on films growth as well as the annealing effect under argon and sulfur atmosphere on as-deposited thin films were studied. The parameters were found to be influential using the Doehlert matrix experimental design methodology. Ranges for a maximum surface mass of films (3 mg cm-2) were determined. A well crystallized major phase of bismuth sulfide with stoichiometric composition was achieved at 190°C for 3 hours. The prepared thin films were characterized using Grazing Incidence X-ray diffraction (GIXRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDX). Second, the band gap energy value was found to be 1.5 eV. Finally, the thermal properties have been studied for the first time by means of the electropyroelectric (EPE) technique. Indeed, the thermal conductivity varied in the range of 1.20 - 0.60 W m-1 K-1 while the thermal diffusivity values increased in terms of the annealing effect ranging from 1.8 to 3.5 10-7 m2s-1This work was financially

Effect of functional brace on threshold of motion sense in patients with Anterior Cruciate Ligament tear
Background and Objective: Anterior Cruciate Ligament (ACL) tear is One of the most common injuries at knee joint. Threshold of motion sense included inputs that are received by mechanical receptors at dynamic position. The objection of present study was to find the effect of functional brace on the Kinesthesia motion sense in patients with ACL rupture.
Materials and Methods: In this Quasi- experimental study, 20 patients with ACL tear, with aging range between 18 to 44 years old were recruited. Patients were selected in a simple non probability sampling manner. Using Continuous passive motion for testing the Kinesthesia motion sense, as a dependent variable. Data was analyzed with Paired t-test and Colmogrof-Smirnof tests.
Results: Threshold of motion sense at affected knee before and after bracing was 3.93±1.67, 4.45±1.86 in open eyes and 3.82±1.61, 4.13±1.96 in closed eyes (P<0.05).
Conclusion: This study showed that the functional brace did not play in important role in the improvement of threshold of motion sense in patients with ACL tear
