Comparative study of anterior knee pain after patelloplasty with and without circumferential denervation in a total knee arthroplasty
...Show More Authors

Background: The anterior knee pain is an important chief complaint of the patients with knee osteoarthritis due to patellofemoral pathology. The pain receptors denervation can be achieved by circumferential denervation of the patellar area by a process of electrocautery.

Objectives: The aim of current study is to assess the pain after total knee arthroplasty (TKA) by patelloplastywith and without circumferential denervation via electrocautery at a minimum follow up with 1 year separately for each patient.

Type of the study:Cross- sectional study.

Methods: Thirty five patients,with mean age of about (62.8) years, were enrolled in this prospective, hospital based study that was held at Al-Yarmouk Teaching Hospital in Baghdad from October 2012 to November 2016. These patients were divided into 2 groups, first group was composed of 19 patients who have TKA with patellar circumferential denervation by electrocautery with  patelloplasty  by removing peripheral osteophytes of patella , the second group of 16 patients were undergone TKA without denervation, but only patelloplasty. The second group was considered as the control group. Visual analogue scale (VAS) was used to evaluate pain pre and post operatively. The patient’s functional ability was assessed by knee society score (KSS) also before and after TKA for both groups and pain killer was given according to patients need.

 

Results: All of the patients were followed for 12 months period. No drugs were used other than occasional use of pain killers in first month after operation for all patients in group one of study. On VAS scale, significant statistical difference in pre and post-operative scales were noticed between both groups of study.  The Knee Society Scale (KSS) was showing a non- significant statistical significance between both study groups before and after TKA. ConclusionA: nterior knee pain can be reduced through the use of patelloplasty with circumferential denervation of patella byelectrocautery, compared with non- denervated procedure. Good clinical outcome was also present.

Exploring the Effects of European Union Conditionality Language on European Mediterranean Human Rights Dialogue
...Show More Authors

Since more than a decade, human rights dialogue in the European Mediterranean Region has been marked by a number of tensions. Although a number of factors contribute to such disputes, the effect of human rights conditionality, which ties EU economic cooperation progression with partner countries human rights advancement, on the dialogue has not been studied. Understanding the aspects, impacts, and effects of conditionality on Euro-Med relations is crucial for furthering dialogue. Yet this variable has been almost entirely neglected in academic and policy research. The research concludes several direct and indirect impacts of conditionality on human rights dialogue using a mixed methodology approach. Direct effects are reflected in the wi

Design of Achromatic Combined Quadrupole Lens Using the Modified Bell-Shaped Field Distribution Model
...Show More Authors

The optimization calculations are made to find the optimum properties of combined quadrupole lens consist of electrostatic and magnetic lenses to produce achromatic lens. The modified bell-shaped model is used and the calculation is made by solving the equation of motion and finding the transfer matrices in convergence and divergence planes, these matrices are used to find the properties of lens as the magnification and aberrations coefficients. To find the optimum values of chromatic and spherical aberrations coefficients, the effect of both the excitation parameter of the lens (n) and the effective length of the lens into account as effective parameters in the optimization processing

Analysis of Magnetorheological Normally Close Directional Control Valve: Magnetorheological normally close directional control valve
...Show More Authors

This valve is intended for use in valves for steering movement, using the qualities of the Magneto-rheological (MR) fluid to regulate the fluid, direct contact without the utilization of moving parts like a spool, a connection between electric flux, and fluid power was made, The simulation was done to employ the" finite element method of magnetism (FEMM)" to arrive at the best design. This software is used for magnetic resonance valve finite element analysis. The valve's best performance was obtained by using a closed directional control valve in the normal state normally closed (NC) MR valve, with simulation results revealing the optimum magnetic flux density in the absence of a current and the shedding condition, as well as the optimum

The influence of no-core fibre length on the sensitivity Optical fibre Humidity sensor
...Show More Authors

Abstract: Reflection optical fibre Humidity sensor is presented in this work, which is based on no core fibre prepared by splicing a segment of no core fibre (NCF) at different lengths 1-6 cm with fixed diameter 125 µm and a single mode fibre (SMF). The range of humidity inside the chamber is controlled from 30% to 90% RH at temperature ~ 30 °С. The experimental result shows that the resonant wavelength dip shift decreases linearly with an increment of RH% and the sensitivity of the sensor increased linearly with an increasing in the length of NCF. However, a high sensitivity 716.07pm/RH% is obtained at length 5cm with good stability and reputability.  Furthermore, the sensor is shif

Blood Vessels Detection of Diabetic Retinopathy from Retinal Fundus Image using Image Processing Techniques
...Show More Authors

 

Early detection of eye diseases can forestall visual deficiency and vision loss. There are several types of human eye diseases, for example, diabetic retinopathy, glaucoma, arteriosclerosis, and hypertension. Diabetic retinopathy (DR) which is brought about by diabetes causes the retinal vessels harmed and blood leakage in the retina. Retinal blood vessels have a huge job in the detection and treatment of different retinal diseases. Thus, retinal vasculature extraction is significant to help experts for the finding and treatment of systematic diseases. Accordingly, early detection and consequent treatment are fundamental for influenced patients to protect their vision. The aim of this paper is to detect blood vessels from

High-Performance Multithreaded Acceleration of High-Order Discrete Racah Polynomials on Multi-Core Architectures
...Show More Authors

Discrete Racah polynomials (DRPs) are considered essential for several applications such as approximation theory, quantum physics, and digital signal processing. However, the computation of high-order DRPs presents significant numerical and computational challenges. Even though the recent advancements in algorithms have improved numerical stability, the inherently sequential nature of these algorithms continues to be a bottleneck for large-scale implementations. This paper proposes a new multithreading-based algorithm for computing the DRP coefficients. The proposed algorithm is designed to accelerate the computation of high-order DRPs by considering the advantages of the independence of different tasks and the ability to process mu

Treatment of Waste Extract Lubricating Oil by Catalytic Cracking Process to Produce Light Fractions
...Show More Authors

The catalytic cracking of three feeds of extract lubricating oil, that produced as a by-product from the process of furfural extraction of lubricating oil base stock in AL-Dura refinery at different operating condition, were carried out at a fixed bed laboratory reactor. The initial boiling point for these feeds was 140 ºC for sample (1), 86 ºC for sample (2) and 80 ºC for sample (3). The catalytic cracking processes were carried out at temperature range 325-400 ºC and initially at atmospheric pressure after 30 minutes over 9.88 % HY-zeolite catalyst load. The comparison between the conversion at different operating conditions of catalytic cracking processes indicates that a high yield was obtained at 375°C, according to gasoline pr
