a multifactorial disease characterized by a progressive degradation of articular cartilage and is the leading cause of disability in elderly persons. IL-18 contributes to the destruction of cartilage and bone in the disease process of arthritis. The aim of the study was to investigate the role of IL-18 in primary knee OA patients. Serum level of IL-18 was assessed by enzyme-linked immunosorbent assay in 30 primary knee OA patients and compared to 20 age and gender-matched healthy volunteers as a control group. Radiographic severity of OA was assessed by Kellgren and Lawrence (KL) global scale. Pain, stiffness and functional assessment were done using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). OA patients had significantly higher serum IL-18 level than in control group (420.93 ± 345.4 versus 151.03 ± 144.16 pg/ml, P=0.001). Serum level of IL-18 was positively correlated with KL global scale (P=0.001). There were no statistically significant correlations between serum level of IL-18 and pain, stiffness, function subscales and total WOMAC index scores among the studied patients. In conclusions, IL-18 has a role in the pathogenesis of OA and it is positively correlated with the radiographic damage of OA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Interlukin-18" title="Interlukin-18">Interlukin-18</a>, <a href="https://publications.waset.org/abstracts/search?q=knee%20osteoarthritis" title=" knee osteoarthritis"> knee osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20osteoarthritis" title=" primary osteoarthritis"> primary osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=WOMAC%20scale" title=" WOMAC scale"> WOMAC scale</a> </p> <a href="https://publications.waset.org/abstracts/46517/role-of-interlukin-18-in-primary-knee-osteoarthritis-clinical-laboratory-and-radiological-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46517.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5996</span> Glycosaminoglycan, a Cartilage Erosion Marker in Synovial Fluid of Osteoarthritis Patients Strongly Correlates with WOMAC Function Subscale</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priya%20Kulkarni">Priya Kulkarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumya%20Koppikar"> Soumya Koppikar</a>, <a href="https://publications.waset.org/abstracts/search?q=Narendrakumar%20Wagh"> Narendrakumar Wagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhanshri%20Ingle"> Dhanshri Ingle</a>, <a href="https://publications.waset.org/abstracts/search?q=Onkar%20Lande"> Onkar Lande</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhay%20Harsulkar">Abhay Harsulkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cartilage is an extracellular matrix composed of aggrecan, which imparts it with a great tensile strength, stiffness and resilience. Disruption in cartilage metabolism leading to progressive degeneration is a characteristic feature of Osteoarthritis (OA). The process involves enzymatic depolymerisation of cartilage specific proteoglycan, releasing free glycosaminoglycan (GAG). This released GAG in synovial fluid (SF) of knee joint serves as a direct measure of cartilage loss, however, limited due to its invasive nature. Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used for assessing pain, stiffness and physical-functions in OA patients. The scale is comprised of three subscales namely, pain, stiffness and physical-function, intends to measure patient’s perspective of disease severity as well as efficacy of prescribed treatment. Twenty SF samples obtained from OA patients were analysed for their GAG values in SF using DMMB based assay. LK 1.0 vernacular version was used to attain WOMAC scale. The results were evaluated using SAS University software (Edition 1.0) for statistical significance. All OA patients revealed higher GAG values compared to the control value of 78.4±30.1µg/ml (obtained from our non-OA patients). Average WOMAC calculated was 51.3 while pain, stiffness and function estimated were 9.7, 3.9 and 37.7, respectively. Interestingly, a strong statistical correlation was established between WOMAC function subscale and GAG (p = 0.0102). This subscale is based on day-to-day activities like stair-use, bending, walking, getting in/out of car, rising from bed. However, pain and stiffness subscale did not show correlation with any of the studied markers and endorsed the atypical inflammation in OA pathology. On one side, where knee pain showed poor correlation with GAG, it is often noted that radiography is insensitive to cartilage degenerative changes; thus OA remains undiagnosed for long. Moreover, active cartilage degradation phase remains elusive to both, patient and clinician. Through analysis of large number of OA patients we have established a close association of Kellgren-Lawrence grades and increased cartilage loss. A direct attempt to correlate WOMAC and radiographic progression of OA with various biomarkers has not been attempted so far. We found a good correlation in GAG levels in SF and the function subscale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cartilage" title="cartilage">cartilage</a>, <a href="https://publications.waset.org/abstracts/search?q=Glycosaminoglycan" title=" Glycosaminoglycan"> Glycosaminoglycan</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20fluid" title=" synovial fluid"> synovial fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20ontario%20and%20McMaster%20Universities%20Arthritis%20Index" title=" western ontario and McMaster Universities Arthritis Index"> western ontario and McMaster Universities Arthritis Index</a> </p> <a href="https://publications.waset.org/abstracts/21197/glycosaminoglycan-a-cartilage-erosion-marker-in-synovial-fluid-of-osteoarthritis-patients-strongly-correlates-with-womac-function-subscale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21197.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5995</span> The Effectiveness of Extracorporeal Shockwave Therapy on Pain and Motor Function in Subjects with Knee Osteoarthritis A Systematic Review and Meta-Analysis of Randomized Clinical Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vu%20Hoang%20Thu%20Huong">Vu Hoang Thu Huong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Purpose: The effects of Extracorporeal Shockwave Therapy (ESWT) in the participants with knee osteoarthritis (KOA) were unclear on physical performance although its effects on pain had been investiagted. This study aims to explore the effects of ESWT on pain relief and physical performance on KOA. Methods: The studies with the randomized controlled design to investigate the effects of ESWT on KOA were systematically searched using inclusion and exclusion criteria through seven electronic databases including Pubmed etc. between 1990 and Dec 2022. To summarize those data, visual analog scale (VAS) or pain scores were determined for measure of pain intensity. Range of knee motion, or the scores of physical activities including Lequesne index (LI), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were determined for measure of physical performances. The first evaluate after treatment period was define as the effect of post-treatment period or immediately effect; and the last evaluate was defined as the effect of following period or the end effect in our study. Data analysis was performed using RevMan 5.4.1 software. A significant level was set at p<0.05. Results: Eight studies (number of participant= 499) reporting the ESWT effects on mild-to-moderate severity (Grades I to III Kellgren–Lawrence) of KOA were qualified for meta-analysis. Compared with sham or placebo group, the ESWT group had a significant decrease of VAS rest score (0.90[0.12~1.67] as mean difference [95% confidence interval]) and pain score WOMAC (2.49[1.22~3.76]), and a significant improvement of physical performance with a decrease of the scores of WOMAC activities (8.18[3.97~12.39]), LI (3.47[1.68~5.26]), and KOOS (5.87[1.73~ 10.00]) in the post-treatment period. There were also a significant decrease of WOMAC pain score (2.83[2.12~3.53]) and a significant decrease of the scores of WOMAC activities (9.47[7.65~11.28]) and LI (4.12[2.34 to 5.89]) in the following period. Besides, compared with other treatment groups, ESWT also displayed the improvement in pain and physical performance, but it is not significant. Conclusions: The ESWT was effective and valuable method in pain relief as well as in improving physical activities in the participants with mild-to-moderate KOA. Clinical Relevance: There are the effects of ESWT on pain relief and the improvement of physical performance in the with KOA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knee%20osteoarthritis" title="knee osteoarthritis">knee osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=extracorporeal%20shockwave%20therapy" title=" extracorporeal shockwave therapy"> extracorporeal shockwave therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20relief" title=" pain relief"> pain relief</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20performance" title=" physical performance"> physical performance</a>, <a href="https://publications.waset.org/abstracts/search?q=shockwave" title=" shockwave"> shockwave</a> </p> <a href="https://publications.waset.org/abstracts/167084/the-effectiveness-of-extracorporeal-shockwave-therapy-on-pain-and-motor-function-in-subjects-with-knee-osteoarthritis-a-systematic-review-and-meta-analysis-of-randomized-clinical-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167084.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5994</span> Comparative Study Between Continuous Versus Pulsed Ultrasound in Knee Osteoarthritis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Mohamed%20Fawzy%20Ghuiba">Karim Mohamed Fawzy Ghuiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Aldeen%20Abd%20Al%20Hakeem%20Balbaa"> Alaa Aldeen Abd Al Hakeem Balbaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Shams%20Elbaz"> Shams Elbaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: To compare between the effects continuous and pulsed ultrasound on pain and function in patient with knee osteoarthritis.

Computer navigation improves the accuracy of bone resection in the coronal and sagittal planes. It was also noted that it normalizes the rotational alignment of the femoral component and fully assesses and balances the deformation of soft tissues in the coronal plane. The work is devoted to the advantages of using computer navigation technology in total knee arthroplasty in 62 patients (11 men and 51 women) suffering from gonarthrosis, aged 51 to 83 years, operated using a computer navigation system, followed up to 3 years from the moment of surgery. During the examination, the deformity variant was determined, and radiometric parameters of the knee joints were measured using the Knee Society Score (KSS), Functional Knee Society Score (FKSS), and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scales. Also, functional stress tests were performed to assess the stability of the knee joint in the frontal plane and functional indicators of the range of motion. After surgery, improvement was observed in all scales; firstly, the WOMAC values decreased by 5.90 times, and the median value to 11 points (p < 0.001), secondly KSS increased by 3.91 times and reached 86 points (p < 0.001), and the third one is that FKSS data increased by 2.08 times and reached 94 points (p < 0.001). After TKA, the axis deviation of the lower limbs of more than 3 degrees was observed in 4 patients at 6.5% and frontal instability of the knee joint just in 2 cases at 3.2%., The lower incidence of sagittal instability of the knee joint after the operation was 9.6%. The range of motion increased by 1.25 times; the volume of movement averaged 125 degrees (p < 0.001). Computer navigation increases the accuracy of the spatial orientation of the endoprosthesis components in all planes, reduces the variability of the axis of the lower limbs within ± 3 °, allows you to achieve the best results of surgical interventions, and can be used to solve most basic tasks, allowing you to achieve excellent and good outcomes of operations in 100% of cases according to the WOMAC scale. With diaphyseal deformities of the femur and/or tibia, as well as with obstruction of their medullary canal, the use of computer navigation is the method of choice. The use of computer navigation prevents the occurrence of flexion contracture and hyperextension of the knee joint during the distal sawing of the femur. Using the navigation system achieves high-precision implantation for the endoprosthesis; in addition, it achieves an adequate balance of the ligaments, which contributes to the stability of the joint, reduces pain, and allows for the achievement of a good functional result of the treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knee%20joint" title="knee joint">knee joint</a>, <a href="https://publications.waset.org/abstracts/search?q=arthroplasty" title=" arthroplasty"> arthroplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20navigation" title=" computer navigation"> computer navigation</a>, <a href="https://publications.waset.org/abstracts/search?q=advantages" title=" advantages"> advantages</a> </p> <a href="https://publications.waset.org/abstracts/155605/advantages-of-computer-navigation-in-knee-arthroplasty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5992</span> Plantar Neuro-Receptor Activation in Total Knee Arthroplasty Patients: Impact on Clinical Function, Pain, and Stiffness - A Randomized Controlled Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Woolfrey%20K.">Woolfrey K.</a>, <a href="https://publications.waset.org/abstracts/search?q=Woolfrey%20M."> Woolfrey M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bolton%20C.%20L."> Bolton C.

Despite total knee arthroplasty (TKA) demonstrating high levels of success, 20% of patients report dissatisfaction with their result. VOXX Wellness Stasis Socks are embedded with a proprietary pattern of neuro-receptor activation points that have been proven to activate a precise neuro-response, according to the pattern theory of haptic perception, which stimulates improvements in pain and function. The use of this technology in TKA patients may prove beneficial as an adjunct to recovery as many patients suffer from deficits to their proprioceptive system caused by ligamentous damage and alterations to mechanoreceptors during the procedure. We hypothesized that VOXX Wellness Stasis Socks are a safe, cost-effective, and easily scalable strategy to support TKA patients through their recovery. Design: Double-blinded, placebo-controlled randomized trial. Participants: Patients scheduled to receive TKA were considered eligible for inclusion in the trial. Interventions: Intervention group (I): VOXX Wellness Stasis socks containing receptor point-activation technology. Control group (C): VOXX Wellness Stasis socks without receptor point-activation technology. Sock use during the waking hours x 6 weeks. Main Outcome Measures: Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) questionnaire completed at baseline, 2 weeks, and 6 weeks to assess pain, stiffness, and physical function. Results: Data analysis using SPSS software. P-values, effect sizes, and confidence intervals are reported to assess clinical relevance of the finding. Physical status classifications were compared using t-test. Within-subject and between-subject differences in the mean WOMAC were analyzed by ANOVA. Effect size was analyzed using Cramer’s V. Consistent improvement in WOMAC scores for pain and stiffness at 2 weeks post op in the I over the C group.

While various rehabilitation approaches have been employed, the effectiveness of high-intensity interval training (HIIT) compared to traditional rehabilitation exercises remains unclear. Objective: This randomized controlled trial aimed to compare the effects of HIIT and traditional rehabilitation exercises on pain reduction, functional improvement, and quality of life in individuals with knee OA. Methods: A total of 120 participants diagnosed with knee OA were randomly allocated into two groups: the HIIT group (n=60) and the traditional rehabilitation group (n=60). The HIIT group participated in a 12-week supervised program consisting of high-intensity interval exercises, while the traditional rehabilitation group followed a conventional physiotherapy regimen. Outcome measures included visual analog scale (VAS) pain scores, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Short Form-36 Health Survey (SF-36) at baseline and after the intervention period. Results: Both groups showed significant improvements in pain scores, functional outcomes (WOMAC), and quality of life (SF-36) after 12 weeks of intervention. However, the HIIT group demonstrated superior pain reduction (p<0.001), functional improvement (p<0.001), and physical health-related quality of life (p=0.002) compared to the traditional rehabilitation group. No significant differences were observed in mental health-related quality of life between the two groups. Conclusion: High-intensity interval training appears to be a more effective rehabilitation approach than traditional exercises for individuals with knee osteoarthritis, resulting in greater pain reduction, improved function, and enhanced physical health-related quality of life. These findings suggest that HIIT may represent a promising intervention strategy for managing knee OA and enhancing the overall well-being of affected individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knee%20osteoarthritis" title="knee osteoarthritis">knee osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=high-intensity%20interval%20training" title=" high-intensity interval training"> high-intensity interval training</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20rehabilitation%20exercises" title=" traditional rehabilitation exercises"> traditional rehabilitation exercises</a>, <a href="https://publications.waset.org/abstracts/search?q=randomized%20controlled%20trial" title=" randomized controlled trial"> randomized controlled trial</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20reduction" title=" pain reduction"> pain reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20improvement" title=" functional improvement"> functional improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/174118/effects-of-high-intensity-interval-training-versus-traditional-rehabilitation-exercises-on-functional-outcomes-in-patients-with-knee-osteoarthritis-a-randomized-controlled-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174118.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5990</span> Correlation Study between Clinical and Radiological Findings in Knee Osteoarthritis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20A.%20A.%20Mohamed">Nabil A.

Recently, impaired proprioceptive accuracy of the knee has been proposed as a local factor in the onset and progression of radiographic knee OA (ROA). Purpose: To compare the clinical and radiological findings in healthy with that of knee OA. Also, to determine if there is a correlation between the clinical and radiological findings in patients with knee OA. Subjects: Fifty one patients diagnosed as unilateral or bilateral knee OA with age ranged between 35-70 years, from both gender without any previous history of knee trauma or surgery, and twenty one normal subjects with age ranged from 35 - 68 years. METHODS: peak torque/body weight (PT/BW) was recorded from knee extensors at isokinetic isometric mode at angle of 45 degree. Also, the Absolute Angular Error was recorded at 45O and 30O to measure joint position sense (JPS). They made anteroposterior (AP) plain X-rays from standing semiflexed knee position and their average score of Timed Up and Go test(TUG) and WOMAC were recorded as a measure of knee pain, stiffness and function. Comparison between the mean values of different variables in the two groups was performed using unpaired student t test. The P value less or equal to 0.05 was considered significant. Results: There were significant differences between the studied variables between the experimental and control groups except the values of AAE at 30O. Also, there were no significant correlation between the clinical findings (pain, function, muscle strength and proprioception) and the severity of arthritic changes in X-rays. CONCLUSION: From the finding of the current study we can conclude that there were a significant difference between the both groups in all studied parameters (the WOMAC, functional level, quadriceps muscle strength and the joint proprioception). Also this study did not support the dependency on radiological findings in management of knee OA as the radiological features did not necessarily indicate the level of structural damage of patients with knee OA and we should consider the clinical features in our treatment plan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20position%20sense" title="joint position sense">joint position sense</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20torque" title=" peak torque"> peak torque</a>, <a href="https://publications.waset.org/abstracts/search?q=proprioception" title=" proprioception"> proprioception</a>, <a href="https://publications.waset.org/abstracts/search?q=radiological%20knee%20osteoarthritis" title=" radiological knee osteoarthritis "> radiological knee osteoarthritis </a> </p> <a href="https://publications.waset.org/abstracts/33164/correlation-study-between-clinical-and-radiological-findings-in-knee-osteoarthritis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33164.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5989</span> Developing of Attitude towards Using Complementary Treatments Scale in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ay%C5%9Feg%C3%BCl%20Bilge">Ayşegül Bilge</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20U%C4%9Furyol"> Merve Uğuryol</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eeyda%20D%C3%BClgerler"> Şeyda Dülgerler</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Y%C4%B1ld%C4%B1z"> Mustafa Yıldız</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research is to prove the Attitude towards Using Complementary Treatments Scale reliability and validity. The research is a methodological type of research that has been planned to determine the validity and reliability of the Attitude towards Using Complementary Treatments Scale. The scale has been developed by the researchers. In the scale, there are 23 questions including complementary and modern therapies individuals apply when they have health problems 4-item Likert-type evaluation has been carried out in preparing the questionnaire. High score obtained from the scale indicates a positive attitude towards complementary therapies. In the course of validity assessment of the scale, expert opinion has been received, and the content validity of the scale has been determined by using Kendall coefficient correlation test (Wa=0.200, p = 0.460). In the course of the reliability assessment of the scale, total score correlations of 23 materials have been examined, and those under 0.20 correlation limit has been removed from the scale correlation. As a result, the scale was left to be 13 items. In the internal consistency tests of the analyses, Cronbach's alpha value has been found to be 0.79. As a result, of the validity analyses of the Attitude towards Using Complementary Treatments Scale, the content and language validity analyses has been found to be at the expected level. It has been determined to be a highly reliable scale as the result of the reliability analyses. In conclusion, Attitude towards Using Complementary Treatments Scale is a valid and reliable scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20health%20care" title="alternative health care">alternative health care</a>, <a href="https://publications.waset.org/abstracts/search?q=complementary%20treatment" title=" complementary treatment"> complementary treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=instrument%20development" title=" instrument development"> instrument development</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing%20practice" title=" nursing practice"> nursing practice</a> </p> <a href="https://publications.waset.org/abstracts/48134/developing-of-attitude-towards-using-complementary-treatments-scale-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48134.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">399</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5988</span> Pharmaceutical Scale up for Solid Dosage Forms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Shashank%20Tiwari">A.

Mahapatra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scale-up is defined as the process of increasing batch size. Scale-up of a process viewed as a procedure for applying the same process to different output volumes. There is a subtle difference between these two definitions: batch size enlargement does not always translate into a size increase of the processing volume. In mixing applications, scale-up is indeed concerned with increasing the linear dimensions from the laboratory to the plant size. On the other hand, processes exist (e.g., tableting) where the term ‘scale-up’ simply means enlarging the output by increasing the speed. To complete the picture, one should point out special procedures where an increase of the scale is counterproductive and ‘scale-down’ is required to improve the quality of the product. In moving from Research and Development (R&D) to production scale, it is sometimes essential to have an intermediate batch scale. This is achieved at the so-called pilot scale, which is defined as the manufacturing of drug product by a procedure fully representative of and simulating that used for full manufacturing scale. This scale also makes it possible to produce enough products for clinical testing and to manufacture samples for marketing. However, inserting an intermediate step between R&D and production scales does not, in itself, guarantee a smooth transition. A well-defined process may generate a perfect product both in the laboratory and the pilot plant and then fail quality assurance tests in production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scale%20up" title="scale up">scale up</a>, <a href="https://publications.waset.org/abstracts/search?q=research" title=" research"> research</a>, <a href="https://publications.waset.org/abstracts/search?q=size" title=" size"> size</a>, <a href="https://publications.waset.org/abstracts/search?q=batch" title=" batch"> batch</a> </p> <a href="https://publications.waset.org/abstracts/35060/pharmaceutical-scale-up-for-solid-dosage-forms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35060.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5987</span> Delamination of Scale in a Fe Carbon Steel Surface by Effect of Interface Roughness and Oxide Scale Thickness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20M.%20Lee">J.

Among several mechanisms of this delamination behavior, the normal tensile stress to the substrate-scale interface has been described as one of the main factors. The stress distribution at the interface is also known to be affected by thermal expansion mismatch between substrate and oxide scale, creep behavior during cooling and the geometry of the interface. In this study, stress states near the interface in a Fe carbon steel with oxide scale have been investigated using FE simulations. The thermal and mechanical properties of oxide scales are indicated in literature and Fe carbon steel is measured using tensile testing machine. In particular, the normal and shear stress components developed at the interface during bending are investigated. Preliminary numerical sensitivity analyses are provided to explain the effects of the interface geometry and oxide thickness on the delamination behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxide%20scale" title="oxide scale">oxide scale</a>, <a href="https://publications.waset.org/abstracts/search?q=delamination" title=" delamination"> delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe%20analysis" title=" Fe analysis"> Fe analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=roughness" title=" roughness"> roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=thickness" title=" thickness"> thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20state" title=" stress state"> stress state</a> </p> <a href="https://publications.waset.org/abstracts/43731/delamination-of-scale-in-a-fe-carbon-steel-surface-by-effect-of-interface-roughness-and-oxide-scale-thickness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43731.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5986</span> Development of the ‘Teacher’s Counselling Competence Self-Efficacy Scale’</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riin%20Seema">Riin Seema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Guidance and counseling as a whole-school responsibility is a global trend. Counseling is a specific competence, that consist of cognitive, emotional, attitudinal, and behavioral components. To authors best knowledge, there are no self-assessment scales for teachers in the whole world to measure teachers’ counseling competency. In 2016 an Estonian scale on teachers counseling competence was developed during an Interdisciplinary Project at Tallinn University. The team consisted of 10 interdisciplinary students (psychology, nursery school, special and adult education) and their supervisor. In 2017 another international Interdisciplinary Project was carried out for adapting the scale in English for international students. Firstly, the Estonian scale was translated by 2 professional translators, and then a group of international Erasmus students (again from psychology, nursery school, special and adult education) selected the most suitable translation for the scale. The developed ‘Teacher’s Counselling Competence Self-Efficacy Scale’ measures teacher’s self-efficacy beliefs in their own competence to perform different counseling tasks (creating a counseling relationship, using different reflection techniques, etc.). The scale consists of 47 questions in a 5-point numeric scale. The scale is created based on counseling theory and scale development and validation theory. The scale has been used as a teaching and learning material for counseling courses by 174 Estonian and 10 international student teachers. After filling out the scale, the students also reflected on the scale and their own counseling competencies. The study showed that the scale is unidimensional and has an excellent Cronbach alpha coefficient. Student’s qualitative feedback on the scale has been very positive, as the scale supports their self-reflection. In conclusion, the developed ‘Teacher’s Counselling Competence Self-Efficacy Scale’ is a useful tool for supporting student teachers’ learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=competency" title="competency">competency</a>, <a href="https://publications.waset.org/abstracts/search?q=counseling" title=" counseling"> counseling</a>, <a href="https://publications.waset.org/abstracts/search?q=self-efficacy" title=" self-efficacy"> self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20students" title=" teacher students"> teacher students</a> </p> <a href="https://publications.waset.org/abstracts/105348/development-of-the-teachers-counselling-competence-self-efficacy-scale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105348.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5985</span> Experimental Investigation of Fluid Dynamic Effects on Crystallisation Scale Growth and Suppression in Agitation Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanjit%20Das">Prasanjit Das</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20K.%20Khan"> M.

To better understand scale growth and suppression, an experimental model is proposed in this study for supersaturated crystallised solutions commonly found in mineral process plants. In this experiment, surface crystallisation of potassium nitrate (KNO3) on the wall of the agitation tank and agitation effects on the scale growth and suppression are studied. The new quantitative scale suppression model predicts that at lower agitation speed, the scale growth rate is enhanced and at higher agitation speed, the scale suppression rate increases due to the increased flow erosion effect. A lab-scale agitation tank with and without baffles were used as a benchmark in this study. The fluid dynamic effects on scale growth and suppression in the agitation tank with three different size impellers (diameter 86, 114, 160 mm and model A310 with flow number 0.56) at various ranges of rotational speed (up to 700 rpm) and solution with different concentration (4.5, 4.75 and 5.25 mol/dm3) were investigated. For more elucidation, the effects of the different size of the impeller on wall surface scale growth and suppression rate as well as bottom settled scale accumulation rate are also discussed. Emphasis was placed on applications in the mineral industry, although results are also relevant to other industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agitation%20tank" title="agitation tank">agitation tank</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallisation" title=" crystallisation"> crystallisation</a>, <a href="https://publications.waset.org/abstracts/search?q=impeller%20speed" title=" impeller speed"> impeller speed</a>, <a href="https://publications.waset.org/abstracts/search?q=scale" title=" scale"> scale</a> </p> <a href="https://publications.waset.org/abstracts/80970/experimental-investigation-of-fluid-dynamic-effects-on-crystallisation-scale-growth-and-suppression-in-agitation-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80970.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">223</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5984</span> The Development of the Self-concept Scale for Elders in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ting-Chia%20Lien">Ting-Chia Lien</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzu-Yin%20Yen"> Tzu-Yin Yen</a>, <a href="https://publications.waset.org/abstracts/search?q=Szu-Fan%20Chen"> Szu-Fan Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tai-chun%20Kuo"> Tai-chun Kuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung-Tse%20Lin"> Hung-Tse Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Chen%20Chung"> Yi-Chen Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hock-Sen%20Gwee"> Hock-Sen Gwee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to explore the result of the survey by developing “Self-Concept Scale for Elders”, which could provide community counseling and guidance institution for practical application.

Several temperature sensors are installed on the grating scale and the temperatures of these sensors are recorded. The temperatures of every point on the grating scale are calculated by interpolating between adjacent sensors. According to the thermal expansion principle, the grating scale thermal expansion error model can be established by doing the integral for the variations of position and temperature. A novel compensation method is proposed in this paper. By applying the established error model, the grating scale thermal expansion error is decreased by 90% compared with no compensation. The residual positioning error of the grating scale is less than 15um/10m and the accuracy of the machine tool is significant improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20expansion%20error%20of%20grating%20scale" title="thermal expansion error of grating scale">thermal expansion error of grating scale</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20compensation" title=" error compensation"> error compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20tools" title=" machine tools"> machine tools</a>, <a href="https://publications.waset.org/abstracts/search?q=integral%20method" title=" integral method"> integral method</a> </p> <a href="https://publications.waset.org/abstracts/34355/grating-scale-thermal-expansion-error-compensation-for-large-machine-tools-based-on-multiple-temperature-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5982</span> Developing New Media Credibility Scale: A Multidimensional Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20Farouk%20Saleh">Hanaa Farouk Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purposes of this study are to develop a scale that reflects emerging theoretical understandings of new media credibility, based on the evolution of credibility studies in western researches, identification of the determinants of credibility in the media and its components by comparing traditional and new media credibility scales and building accumulative scale to test new media credibility. This approach was built on western researches using conceptualizations of media credibility, which focuses on four principal components: Source (journalist), message (article), medium (newspaper, radio, TV, web, etc.), and organization (owner of the medium), and adding user and cultural context as key components to assess new media credibility in particular. This study’s value lies in its contribution to the conceptualization and development of new media credibility through the creation of a theoretical measurement tool. Future studies should explore this scale to test new media credibility, which represents a promising new approach in the efforts to define and measure credibility of all media types. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=credibility%20scale" title="credibility scale">credibility scale</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20credibility%20components" title=" media credibility components"> media credibility components</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20media%20credibility%20scale" title=" new media credibility scale"> new media credibility scale</a>, <a href="https://publications.waset.org/abstracts/search?q=scale%20development" title=" scale development"> scale development</a> </p> <a href="https://publications.waset.org/abstracts/40031/developing-new-media-credibility-scale-a-multidimensional-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40031.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">321</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5981</span> Impacts of Financial Development and Operational Scale on Bank Efficiencies in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying-Hsiu%20Chen">Ying-Hsiu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Pao-Peng%20Hsu"> Pao-Peng Hsu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper adopts a two-stage data envelopment analysis to explore the impacts of financial development and bank operational scale on bank efficiencies.

Yet, a controversy still persists on the appropriate operative technique that doesn’t affect proprioception much. Purpose: This study compared the effects of Cruciate Retaining (CR) and Posterior Stabilized (PS) total knee arthroplasty (TKA on dynamic balance, pain and functional performance following rehabilitation. Methods: Thirty patients with CRTKA (group I), thirty with PSTKA (group II) and fifteen indicated for arthroplasty but weren’t operated on yet (group III) participated in the study. The mean age was 54.53±3.44, 55.13±3.48 and 55.33±2.32 years and BMI 35.7±3.03, 35.7±1.99 and 35.73±1.03 kg/m2 for group I, II, and III respectively. The Berg Balance Scale (BBS), WOMAC pain subscale and Timed-Up-and-Go (TUG) and Stair-Climbing (SC) tests were used for assessment. Assessments were conducted four weeks pre- and post-operatively, three, six and twelve months post-operatively with the control group being assessed at the same time intervals. The post-operative rehabilitation involved hospitalization (1st week), home-based (2nd-4th weeks), and outpatient clinic (5th-12th weeks) programs, follow-up to all groups for twelve months. Results: The Mixed design MANOVA revealed that group I had significantly lower pain scores and SC time compared with group II three, six and twelve months post-operatively. Moreover, the BBS scores increased significantly and the pain scores and TUG and SC time decreased significantly six months post-operatively compared with four weeks pre- and post-operatively and three months post-operatively in group I and II with the opposite being true four weeks post-operatively. But no significant differences in BBS scores, pain scores and TUG and SC time between six and twelve months post-operatively in group I and II. Interpretation/Conclusion: CRTKA is preferable to PSTKA, possibly due to the preserved human proprioceptors in the un-excised PCL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20balance" title="dynamic balance">dynamic balance</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20performance" title=" functional performance"> functional performance</a>, <a href="https://publications.waset.org/abstracts/search?q=knee%20arthroplasty" title=" knee arthroplasty"> knee arthroplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term" title=" long-term"> long-term</a> </p> <a href="https://publications.waset.org/abstracts/18917/long-term-follow-up-of-dynamic-balance-pain-and-functional-performance-in-cruciate-retaining-posterior-stabilized-total-knee-arthroplasty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18917.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5975</span> Adjustment and Scale-Up Strategy of Pilot Liquid Fermentation Process of Azotobacter sp.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Quiroga-Cubides">G.

In order to obtain significantly viable cellular concentration, a scale-up strategy for a liquid fermentation process (SmF) with two strains of <em>A. chroococcum </em>(named Ac1 and Ac10) was validated and adjusted at laboratory and pilot scale. A batch fermentation process under previously defined conditions was carried out on a biorreactor Infors®, model Minifors of 3.5 L, which served as a baseline for this research. For the purpose of increasing process efficiency, the effect of the reduction of stirring speed was evaluated in combination with a fed-batch-type fermentation laboratory scale. To reproduce the efficiency parameters obtained, a scale-up strategy with geometric and fluid dynamic behavior similarities was evaluated. According to the analysis of variance, this scale-up strategy did not have significant effect on cellular concentration and in laboratory and pilot fermentations (Tukey, p > 0.05). Regarding air consumption, fermentation process at pilot scale showed a reduction of 23% versus the baseline. The percentage of reduction related to energy consumption reduction under laboratory and pilot scale conditions was 96.9% compared with baseline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azotobacter%20chroococcum" title="Azotobacter chroococcum">Azotobacter chroococcum</a>, <a href="https://publications.waset.org/abstracts/search?q=scale-up" title=" scale-up"> scale-up</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20fermentation" title=" liquid fermentation"> liquid fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=fed-batch%20process" title=" fed-batch process"> fed-batch process</a> </p> <a href="https://publications.waset.org/abstracts/57291/adjustment-and-scale-up-strategy-of-pilot-liquid-fermentation-process-of-azotobacter-sp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57291.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">440</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5974</span> Scaling-Down an Agricultural Waste Biogas Plant Fermenter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matheus%20%20Pessoa">Matheus Pessoa</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthias%20Kraume"> Matthias Kraume</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scale-Down rules in process engineering help us to improve and develop Industrial scale parameters into lab scale.

One of the major issues inside the oil industry is how to control scale formation, regardless of whether it is in the wellhead equipment, down-hole pipelines or even the actual field formation. The best approach to handle the challenge associated with oilfield scale formation is the application of scale inhibitors to avert the scale formation. Chemical inhibitors have been employed in doing such. But due to environmental regulations, the industry have focused on using green scale inhibitors to mitigate the formation of scales. This paper compares the scale inhibition performance of Polyaspartic acid and sodium polyacrylic acid, both commercial green scale inhibitors, in mitigating silicate scales formed during Alkaline/Surfactant/polymer flooding under static conditions. Both PASP and TH5000 are non-threshold inhibitors, therefore their efficiency was only seeing in delaying the deposition of the silicate scales. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline%2Fsurfactant%2Fpolymer%20flooding%20%28ASP%29" title="alkaline/surfactant/polymer flooding (ASP)">alkaline/surfactant/polymer flooding (ASP)</a>, <a href="https://publications.waset.org/abstracts/search?q=polyaspartic%20acid%20%28PASP%29" title=" polyaspartic acid (PASP)"> polyaspartic acid (PASP)</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20polyacrylate%20%28SPA%29" title=" sodium polyacrylate (SPA)"> sodium polyacrylate (SPA)</a> </p> <a href="https://publications.waset.org/abstracts/29025/a-comparative-performance-of-polyaspartic-acid-and-sodium-polyacrylate-on-silicate-scale-inhibition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29025.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">351</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5972</span> Effects of Employees’ Training Program on the Performance of Small Scale Enterprises in Oyo State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Itiola%20Kehinde%20Adeniran">Itiola Kehinde Adeniran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study examined the effect of employees’ training on the performance of small scale enterprises in Oyo State.

When analyzing these patterns and processes, a key issue has been to determine the proper spatial scale. In addition, it is important to consider the possibility that these patterns and processes might differ appreciably for different temporal scales and might vary across geographic units of analysis. We examine the spatial-temporal dependence of residential burglary. This dependence is tested at varying geographical scales and temporal aggregations. The analyses are based on recorded incidents of crime in Columbus, Ohio during the 1994-2002 period. We implement point pattern analysis on the crime points using Ripley’s K function. The results indicate that spatial point patterns of residential burglary reveal spatial scales of clustering relatively larger than the average size of census tracts of the study area. Also, spatial scale is independent of temporal scale. The results of our analyses concerning the geographic scale of spatial patterns and processes can inform the development of effective policies for crime control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inhomogeneous%20K%20function" title="inhomogeneous K function">inhomogeneous K function</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20burglary" title=" residential burglary"> residential burglary</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20point%20pattern" title=" spatial point pattern"> spatial point pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20scale" title=" spatial scale"> spatial scale</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20scale" title=" temporal scale"> temporal scale</a> </p> <a href="https://publications.waset.org/abstracts/92371/spatial-scale-of-clustering-of-residential-burglary-and-its-dependence-on-temporal-scale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92371.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5970</span> Produced Water Treatment Using Novel Solid Scale Inhibitors Based on Silver Tungstate Loaded Kit-6: Static and Modeling Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Hosny">R.

Scale issues cost the industry millions of dollars in damage and lost production every year. One of the main causes of global production decline is scale. In this study, solid scale inhibitors based on silver tungstate loaded KIT-6 were synthesized and evaluated in both static and scale inhibition modeling. The silver tungstate loaded KIT-6 catalysts were synthesized via a simple impregnated method using 3D mesoporous KIT-6 as support. The synthesized materials were characterized using wide and low XRD, N2 adsorption–desorption analysis, TGA analysis, and FTIR, SEM, and XPS analysis. The scale inhibition efficiency of the synthesized materials was evaluated using a static scale inhibition test. The results of this study demonstrate the potential application of silver tungstate-loaded KIT-6 solid scale inhibitors for the oil and gas industry. The results of this study will contribute to the development of new and innovative solid scale inhibitors based on silver tungstate-loaded KIT-6. The inhibition efficiency of the scale inhibitor increases, and calcite scale inhibitor decreases with increasing pH (2 to8), it proposes that the scale inhibitor was more effective under alkaline conditions. An inhibition efficiency of 99% on calcium carbonate can be achieved at the optimal dosage of 7.5 ppm at 55oC, indicating that the scale inhibitor exhibits a relatively good inhibition performance on calcium carbonate. The use of these materials can potentially lead to more efficient and cost-effective solutions for scaling inhibition in various industrial processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=produced%20water%20treatment" title="produced water treatment">produced water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20scale%20inhibitors" title=" solid scale inhibitors"> solid scale inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=calcite" title=" calcite"> calcite</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20tungestate" title=" silver tungestate"> silver tungestate</a>, <a href="https://publications.waset.org/abstracts/search?q=3%20D%20mesoporous%20KIT-6" title=" 3 D mesoporous KIT-6"> 3 D mesoporous KIT-6</a>, <a href="https://publications.waset.org/abstracts/search?q=oilfield%20scales" title=" oilfield scales"> oilfield scales</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a> </p> <a href="https://publications.waset.org/abstracts/171177/produced-water-treatment-using-novel-solid-scale-inhibitors-based-on-silver-tungstate-loaded-kit-6-static-and-modeling-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171177.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5969</span> Deproteinization of Moroccan Sardine (Sardina pilchardus) Scales: A Pilot-Scale Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Bellali">F.

Those underutilized resources particularly scales contain a large amount of proteins and calcium. Sardina plichardus scales from resulting from the transformation operation have the potential to be used as raw material for the collagen production. Taking into account this strong expectation of the regional fish industry, scales sardine upgrading is well justified. In addition, political and societal demands for sustainability and environment-friendly industrial production systems, coupled with the depletion of fish resources, drive this trend forward. Therefore, fish scale used as a potential source to isolate collagen has a wide large of applications in food, cosmetic, and biomedical industry. The main aim of this study is to isolate and characterize the acid solubilize collagen from sardine fish scale, Sardina pilchardus. Experimental design methodology was adopted in collagen processing for extracting optimization. The first stage of this work is to investigate the optimization conditions of the sardine scale deproteinization on using response surface methodology (RSM). The second part focus on the demineralization with HCl solution or EDTA. And the last one is to establish the optimum condition for the isolation of collagen from fish scale by solvent extraction. The advancement from lab scale to pilot scale is a critical stage in the technological development. In this study, the optimal condition for the deproteinization which was validated at laboratory scale was employed in the pilot scale procedure. The deproteinization of fish scale was then demonstrated on a pilot scale (2Kg scales, 20l NaOH), resulting in protein content (0,2mg/ml) and hydroxyproline content (2,11mg/l). These results indicated that the pilot-scale showed similar performances to those of lab-scale one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deproteinization" title="deproteinization">deproteinization</a>, <a href="https://publications.waset.org/abstracts/search?q=pilot%20scale" title=" pilot scale"> pilot scale</a>, <a href="https://publications.waset.org/abstracts/search?q=scale" title=" scale"> scale</a>, <a href="https://publications.waset.org/abstracts/search?q=sardine%20pilchardus" title=" sardine pilchardus"> sardine pilchardus</a> </p> <a href="https://publications.waset.org/abstracts/17961/deproteinization-of-moroccan-sardine-sardina-pilchardus-scales-a-pilot-scale-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17961.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5968</span> Efficacy of the Hegab Temporomandibular Joint Splint in Treating Patients Diagnosed with Dystonia with or Without Systemic Involvement: A Report of 14 Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Hegab">Ayman Hegab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dystonia is a neurological motor disorder characterized by involuntary and uncontrollable muscle contractions, tension, twisting, and tremors. The aim of the present study was to analyze the improvement in dystonic contractions in patients with dystonia following the use of a Hegab temporomandibular joint splint (HTS). The Fahn-Marsden Dystonia Movement Scale (DMS) and Disability Scale were used in the current study to evaluate dystonia. An HTS with a thickness ranging from 4 to 6 mm was used to treat the patients enrolled in the study. The final sample comprised 14 patients (10 female and four male) with mean (range) ages of 35.64 (18 to 55) years. Pre-treatment DMS ranged from 6.5 to 57 mean (SD) 18.21 (13.38). At the end of the study, DMS ranged from 0 to 15 mean (SD) 3.14 (3.86). Statistical analysis of the differences between pre-treatment and post-treatment DMS showed a significant decrease in DMS at the end of the treatment period (p = 0.0001). Regarding the disability scale, the pre-treatment disability scale ranged from 7 to 18 mean (SD) 9.46 (3.02). At the end of the study, DMS ranged from 0 to 3 mean (SD) 1.46 (1.13). There was a statistically highly significant decrease in the Disability Scale at the end of the treatment period (p-value 0.0001). This study suggests that the HTS can be considered an effective treatment modality for dystonia, as it significantly decreases both the DMS and the Disability scale. <p
