abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...
Abstract Introduction We determined the association between frailty and 30-day mortality following total hip knee arthroplasty (THA/TKA) due to osteoarthritis also impact of THA/TKA on compared a control population. Method used linked primary secondary care data Office for National Statistics data. Frailty was assessed using electronic index categorised as fit, mild, moderate, severe frailty. T...
Purpose: Developmental dysplasia of the hip (DDH) increases the risk of secondary degenerative changes and subsequent total hip arthroplasty. The postoperative quality of life in patients with DDH who have been born and grown with this disability and adapted to it during the life, is one of the most challenging issues. This study aimed to compare the quality of life of patients with DDH before ...
Background: Short-stem prosthesis for total hip arthroplasty (THA) have been designed to overcome the weakness of standard-stem prostheses and improve surgical outcomes. The aim of this study was to compare short-stem with standard-stem prosthesis outcomes. Methods: This study was performed as a randomized clinical trial. Subjects were selected among patients referred to Sina University Hospit...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
BACKGROUND Patient-reported scoring systems have recently been used after surgical procedures. The purpose of this prospective study was to evaluate the patient-reported outcomes of femoral osteotomy and total hip arthroplasty (THA) for osteonecrosis of the femoral head (ONFH). METHODS Forty-two symptomatic ONFH patients with asymptomatic contralateral hip underwent either transtrochanteric a...
In this paper we study the extremal type problem arising from the question: What is the maximum number ET (S) of edges that a geometric graph G on a planar point set S can have such that it does not contain empty triangles? We prove: ( n 2 ) −O(n log n) ≤ ET (n) ≤ ( n 2 ) − ( n− 2 + ⌊n 8 ⌋) . keywords: Geometric graphs Empty triangles Combinatorial Geometry Extremal Problem ∗Partially supported...
