Methods Three hundred and ninety-four patients with PD were enrolled in Beijing Tiantan Hospital, according to CI level, the patients were divided into PD without cognitive impairment (PD-NCI), PD with mild cognitive impairment (PD-MCI), and PD with dementia (PDD) group. Collect patient's demographic data, including gender, onset age, education level and duration. The cognitive function of PD patients was evaluated by Montreal cognitive assessment (MoCA) scale, and the overall cognitive function and cognitive domains of the three groups were compared.Using v-PSG to assess the sleep status of patients. Correlation analysis of MoCA Scale and v-PSG results in PD-CI group. Results 1. In 394 cases of PD, 94 cases (23.86%) in PD-NCI group , 177 cases(44.92%) in PD-MCI group , 123 cases (31.22%) in PDD group. 2.There was no significant difference in gender, age of onset, education level and duration in PD-NCI group, PD-MCI group and PDD group （P＞0.05）. 3. The total score of MoCA scale in PD-NCI group, PD-MCI group and PDD group decreased one by one. In PD-NCI group, PD-MCI group and PDD group, the scores of each cognitive domain in MoCA scale decreased significantly（P<0.05）. 4.Compared with the PD-MCI group, PDD group had lower total sleep time, lower sleep efficiency （P<0.05）. Compared with PD-NCI group, PDD group had lower total sleep time and lower sleep efficiency （P<0.05）.5. The sleep efficiency of PD-CI patients is positively correlated with the total score of MoCA scale, visual spatial function, executive function, delayed recall and attention score（P<0.05). Conclusions The incidence of CI in PD patients was high; The cognitive function and cognitive domains of PD-CI patients were significantly impaired; In patients with PD-CI, total sleep time decreased, sleep efficiency decreased, and it was related to overall cognitive function and partial cognitive impairment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parkinson%20disease" title="Parkinson disease">Parkinson disease</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20impairment" title=" cognitive impairment"> cognitive impairment</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20characteristics" title=" clinical characteristics"> clinical characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20disorders" title=" sleep disorders"> sleep disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=video-polysomnography" title=" video-polysomnography"> video-polysomnography</a> </p> <a href="https://publications.waset.org/abstracts/188416/the-clinical-characteristics-and-their-relationship-with-sleep-disorders-in-patients-with-parkinson-disease-accompanied-with-cognitive-impairment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188416.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">30</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">14493</span> Effects of Low Sleep Efficiency and Sleep Deprivation on Driver Physical Fatigue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen-Yu%20%20Tsai">Chen-Yu Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Te%20%20Liu"> Wen-Te Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen-Chen%20%20Lo"> Chen-Chen Lo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang%20%20Lo"> Kang Lo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin-Tzu%20%20Lin"> Yin-Tzu Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Driving drowsiness related to insufficient or disordered sleep accounts for a major percentage of vehicular accidents. Sleep deprivation is the primary reason related to low sleep efficiency. Nevertheless, the mechanism of sleep deprivation induces driving fatigue to remain unclear. Objective: The objective of this study is to associate the relationship between insufficient sleep efficiency and driving fatigue. Methodologies: The physical condition while driving was obtained from the questionnaires to classify the state of driving fatigue. Sleep efficiency was quantified as the polysomnography (PSG), and the sleep stages were sentenced by the reregistered Technologist during examination in a hospital in New Taipei City (Taiwan). The independent T-test was used to investigate the correlation between sleep efficiency, sleep stages ratio, and driving drowsiness. Results: There were 880 subjects recruited in this study, who had been done polysomnography for evaluating severity for obstructive sleep apnea syndrome (OSAS) as well as completed the driver condition questionnaire. Four-hundred-eighty-four subjects (55%) were classified as fatigue group, and 396 subjects (45%) were served as the control group. The ratio of stage three sleep (N3) (0.032 ± 0.056) in fatigue group were significantly lower than the control group (p < 0.01). The significantly higher value of snoring index (242.14 ± 205.51 /hours) was observed in the fatigue group (p < 0.01). Conclusion: We observe the considerable correlation between deep sleep reduce and driving drowsiness. To avoid drowsy driving, the sleep deprivation, and the snoring events during the sleeping time should be monitored and alleviated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=driving%20drowsiness" title="driving drowsiness">driving drowsiness</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20deprivation" title=" sleep deprivation"> sleep deprivation</a>, <a href="https://publications.waset.org/abstracts/search?q=stage%20three%20sleep" title=" stage three sleep"> stage three sleep</a>, <a href="https://publications.waset.org/abstracts/search?q=snoring%20index" title=" snoring index"> snoring index</a> </p> <a href="https://publications.waset.org/abstracts/110120/effects-of-low-sleep-efficiency-and-sleep-deprivation-on-driver-physical-fatigue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110120.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">14492</span> Effectiveness of Cognitive and Supportive-Expressive Group Therapies on Self-Efficiency and Life Style in MS Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamran%20Yazdanbakhsh">Kamran Yazdanbakhsh</a>, <a href="https://publications.waset.org/abstracts/search?q=Somayeh%20Mahmoudi"> Somayeh Mahmoudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple sclerosis is the most common chronic disease of the central nervous system associated with demyelination of neurons and several demyelinated parts of the disease encompasses throughout the white matter and affects the sensory and motor function. This study compared the effectiveness of two methods of cognitive therapy and supportive-expressive therapy on the efficacy and quality of life in MS patients. This is an experimental project which has used developed group pretest - posttest and follow-up with 3 groups. The study included all patients with multiple sclerosis in 2013 that were members of the MS Society of Iran in Tehran. The sample included 45 patients with MS that were selected volunteerily of members of the MS society of Iran and randomly divided into three groups and pretest, posttest, and follow-up (three months) for the three groups had been done.The dimensions of quality of life in patients with multiple sclerosis scale, and general self-efficiency scale of Schwarzer and Jerusalem was used for collecting data. The results showed that there was a significant difference between the mean of quality of life scores at pretest, posttest, and follow-up of the experimental groups. There was no significant difference between the mean of quality of life of the experimental groups which means that both groups were effective and had the same effect. There was no significant difference between the mean of self-efficiency scores in control and experimental group in pretest, posttest and follow-up. Thus, by using cognitive and supportive-expressive group therapy we can improve quality of life in MS patients and make great strides in their mental health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20group%20therapy" title="cognitive group therapy">cognitive group therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20style" title=" life style"> life style</a>, <a href="https://publications.waset.org/abstracts/search?q=MS" title=" MS"> MS</a>, <a href="https://publications.waset.org/abstracts/search?q=self-efficiency" title=" self-efficiency"> self-efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=supportive-expressive%20group%20therapy" title=" supportive-expressive group therapy"> supportive-expressive group therapy</a> </p> <a href="https://publications.waset.org/abstracts/20050/effectiveness-of-cognitive-and-supportive-expressive-group-therapies-on-self-efficiency-and-life-style-in-ms-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20050.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">484</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">14491</span> Internal Capital Market Efficiency Study Based on Improved Cash Flow Sensitivity Coefficient - Take Tomorrow Group as an Example</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peng%20Lu">Peng Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Ting"> Liu Ting</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Because of the difficulty of financing from the external capital market, the reorganization and merger of private enterprises have formed a family group, seeking the help of the internal capital market to alleviate the capital demand. However, the inefficiency of the internal capital market can damage the effect it should have played, and even hinder the development of enterprises. This paper takes the "Tomorrow Group" as the research object to carry on the case analysis. After using the improved cash flow sensitivity coefficient to measure the efficiency of the internal capital market of Tomorrow Group, the inefficiency phenomenon is found. Then the analysis reveals that the reasons for its inefficiency include that the pyramidal equity structure is conducive to control, the separation of cash flow rights and control rights, the concentration of equity leads to poor balance, the abandonment of real industries and information asymmetry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tomorrow%20group" title="tomorrow group">tomorrow group</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20capital%20market" title=" internal capital market"> internal capital market</a>, <a href="https://publications.waset.org/abstracts/search?q=related-party%20transactions" title=" related-party transactions"> related-party transactions</a>, <a href="https://publications.waset.org/abstracts/search?q=Baotou%20tomorrow%20technology%20Co." title=" Baotou tomorrow technology Co."> Baotou tomorrow technology Co.</a>, <a href="https://publications.waset.org/abstracts/search?q=LTD" title=" LTD"> LTD</a> </p> <a href="https://publications.waset.org/abstracts/116397/internal-capital-market-efficiency-study-based-on-improved-cash-flow-sensitivity-coefficient-take-tomorrow-group-as-an-example" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116397.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">136</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">14490</span> Efficiency of Treatment in Patients with Newly Diagnosed Destructive Pulmonary Tuberculosis Using Intravenous Chemotherapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kuzhko">M.

Methods: 152 tuberculosis patients were randomized into 2 groups: Main (n=65) who received isoniazid, ethambutol and sodium rifamycin intravenous + pyrazinamide per os and control (n=87) who received all the drugs (isoniazid, rifampicin, ethambutol, pyrazinamide) orally. Results: After 2 weeks of treatment symptoms of intoxication disappeared in 59 (90.7±3.59 %) of patients of the main group and 60 (68.9±4.9 %) patients in the control group, p<0.05. The mean duration of symptoms of intoxication in patients main group was 9.6±0.7 days, in control group – 13.7±0.9 days. After completing intensive phase sputum conversion was found in all the patients main group and 71 (81.6±4.1 %) patients control group p < 0.05. The average time of sputum conversion in main group was 1.6±0.1 months and 1.9±0.1 months in control group, p > 0.05. In patients with destructive pulmonary tuberculosis time to sputum conversion was 1.7±0.1 months in main group and 2.2±0.2 months in control group, p < 0.05.

Conclusions: In patients with newly diagnosed destructive pulmonary tuberculosis use of isoniazid, ethambutol and sodium rifamycin intravenous in the intensive phase of chemotherapy resulted in a significant reduction in terms of the disappearance of symptoms of intoxication and sputum conversion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intravenous%20chemotherapy" title="intravenous chemotherapy">intravenous chemotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20efficiency" title=" treatment efficiency"> treatment efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis%20drugs" title=" tuberculosis drugs"> tuberculosis drugs</a> </p> <a href="https://publications.waset.org/abstracts/61715/efficiency-of-treatment-in-patients-with-newly-diagnosed-destructive-pulmonary-tuberculosis-using-intravenous-chemotherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61715.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">202</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">14489</span> Spectral Clustering for Manufacturing Cell Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yessica%20Nataliani">Yessica Nataliani</a>, <a href="https://publications.waset.org/abstracts/search?q=Miin-Shen%20Yang"> Miin-Shen Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cell formation (CF) is an important step in group technology. It is used in designing cellular manufacturing systems using similarities between parts in relation to machines so that it can identify part families and machine groups. There are many CF methods in the literature, but there is less spectral clustering used in CF. In this paper, we propose a spectral clustering algorithm for machine-part CF. Some experimental examples are used to illustrate its efficiency. Overall, the spectral clustering algorithm can be used in CF with a wide variety of machine/part matrices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=group%20technology" title="group technology">group technology</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20formation" title=" cell formation"> cell formation</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20clustering" title=" spectral clustering"> spectral clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=grouping%20efficiency" title=" grouping efficiency"> grouping efficiency</a> </p> <a href="https://publications.waset.org/abstracts/72294/spectral-clustering-for-manufacturing-cell-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72294.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">407</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">14488</span> Evaluation the Financial and Social Efficiency of Microfinance Institutions Using Data Envelope Analysis - A Sample Study of Active Microfinance Institutions in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiba%20Mezaache">Hiba Mezaache</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aims to assess the financial and social efficiency of microfinance institutions in india for the period 2015-2019 by using two models of economies of scale and choosing the output direction of the data envelope analysis (DEA) method and using the MIX MARKET database.

Unfortunately, so far no tools for a comprehensive assessment of energy efficiency within the production process exist. Therefore the Institute for Factory Automation and Production Systems of the Friedrich-Alexander-University Erlangen-Nuremberg has developed two methods with the goal of achieving transparency and a quantitative assessment of energy efficiency: EEV (Energy Efficiency Value) and EPE (Energetic Process Efficiency). This paper describes the basics and state of the art as well as the developed approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title="energy efficiency">energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency%20value" title=" energy efficiency value"> energy efficiency value</a>, <a href="https://publications.waset.org/abstracts/search?q=energetic%20process%20efficiency" title=" energetic process efficiency"> energetic process efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a> </p> <a href="https://publications.waset.org/abstracts/23200/comprehensive-assessment-of-energy-efficiency-within-the-production-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23200.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">733</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">14486</span> The Impact of Motor Predispositions of Pilot-Cadets on Results in Aviation Synthetic Efficiency Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Wochynski">Zbigniew Wochynski</a>, <a href="https://publications.waset.org/abstracts/search?q=Justyna%20Skrzynska"> Justyna Skrzynska</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Jedrys"> Robert Jedrys</a>, <a href="https://publications.waset.org/abstracts/search?q=Zdzislaw%20Kobos"> Zdzislaw Kobos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study is to determine the types of motor skills and their impact on achieving results while undergoing Aviation Synthetic Efficiency Test (ASET). The study involved 59 cadets, 21 years-old on average, who are studying on first year for a pilot. The average weight of the respondents is 73.8 kg. The subjects were divided into two groups by weight: up to 73.8 kg -group A (n-30) and above 73,8kg -group B (n-29). All subjects underwent the following tests: running at 40m, 100m, 1000m, 2000m, pull-ups, ASET. In both groups, the cadets were divided into two motor skills types taking into advance 40 m running, pull-ups, 2000 meters running and then subjected to do ASET. There has been shown statistically significant increase in group B in body height, weight and BMI with p <0.0003, p <0.0001, p <0.0001 compared to group A. The results indicate that the dominant motor type in all subjects is the endurance-strength model, which reached the speed V = 1,42m/s in overcoming ASET. This is confirmed by the correlation between 2000m and pull-ups r = 0.37 (p <0.05). In group A, the results indicate that the dominant type of motor is a high-speed-endurance model (26.6%), which reached speed V = 1,42m/s in overcoming ASET. In Group B, there was type of motor speed-strength (20.6%), which reached speed of V = 1.45m/s in overcoming ASET. This confirms the correlation between ASET and pull-ups r = 0.56 (p <0.005). Examined cadets who were having one dominant characteristic achieved worse results is ASET. The best results from all examined cadets in overcoming ASET had the type of motor endurance-strength, in group A endurance-speed model and in group B type of speed-strength <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ASET" title="ASET">ASET</a>, <a href="https://publications.waset.org/abstracts/search?q=Aviation%20Synthetic%20Efficiency%20Test" title=" Aviation Synthetic Efficiency Test"> Aviation Synthetic Efficiency Test</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20skills" title=" motor skills"> motor skills</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20tests" title=" physical tests"> physical tests</a>, <a href="https://publications.waset.org/abstracts/search?q=pilot-cadets" title=" pilot-cadets"> pilot-cadets</a> </p> <a href="https://publications.waset.org/abstracts/54307/the-impact-of-motor-predispositions-of-pilot-cadets-on-results-in-aviation-synthetic-efficiency-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54307.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">288</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">14485</span> Effects of Waist-to-Hip Ratio and Visceral Fat Measurements Improvement on Offshore Petrochemical Company Shift Employees' Work Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Essam%20Amerian">Essam Amerian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to investigate the effects of improving waist-to-hip ratio (WHR) and visceral fat components on the health of shift workers in an offshore petrochemical company. A total of 100 male shift workers participated in the study, with an average age of 40.5 years and an average BMI of 28.2 kg/m². The study employed a randomized controlled trial design, with participants assigned to either an intervention group or a control group. The intervention group received a 12-week program that included dietary counseling, physical activity recommendations, and stress management techniques. The control group received no intervention. The outcomes measured were changes in WHR, visceral fat components, blood pressure, and lipid profile. The results showed that the intervention group had a statistically significant improvement in WHR (p<0.001) and visceral fat components (p<0.001) compared to the control group. Furthermore, there were statistically significant improvements in systolic blood pressure (p=0.015) and total cholesterol (p=0.034) in the intervention group compared to the control group. These findings suggest that implementing a 12-week program that includes dietary counseling, physical activity recommendations, and stress management techniques can effectively improve WHR, visceral fat components, and cardiovascular health among shift workers in an offshore petrochemical company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20composition" title="body composition">body composition</a>, <a href="https://publications.waset.org/abstracts/search?q=waist-hip-ratio" title=" waist-hip-ratio"> waist-hip-ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=visceral%20fat" title=" visceral fat"> visceral fat</a>, <a href="https://publications.waset.org/abstracts/search?q=shift%20worker" title=" shift worker"> shift worker</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20efficiency" title=" work efficiency"> work efficiency</a> </p> <a href="https://publications.waset.org/abstracts/166021/effects-of-waist-to-hip-ratio-and-visceral-fat-measurements-improvement-on-offshore-petrochemical-company-shift-employees-work-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166021.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">79</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">14484</span> The Impact of Combined Loading on Lateral Capacity and Group Efficiency of Helical Piles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Hamdy%20Abdulmohsen">Hesham Hamdy Abdulmohsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Shawky%20Abdel%20Aziz"> Ahmed Shawky Abdel Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Fawzy%20Aldaghma"> Mona Fawzy Aldaghma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Helical piles have gained significant attention as efficient alternatives for deep foundations due to their rapid installation process and dual functionality in compression and tension. They experience various combinations of axial and lateral loads. While extensive research has explored helical pile behavior under individual axial or lateral loads, the effects of combined axial compression and lateral loads still need further study. This paper compares experimental and numerical (PLAXIS-3D) results for vertical helical-pile groups under combined loads. The study aims to clarify the impact of key factors, including helix location and lateral load direction, on the lateral capacity of helical-pile groups and, consequently, their overall efficiency. The study concludes that the lateral capacity of the helical-pile group significantly depends on the helix location within the pile shaft length. Optimal lateral performance occurs when helices are positioned at a depth ratio of H/L = 0.4. Furthermore, rectangular plan distribution groups exhibit greater lateral capacity when subjected to lateral loads aligned with their long axis. The presence of vertical compression loading enhances the lateral capacity of the group, with the specific enhancement depending on the value of the vertical compression load, lateral load direction, and helix location. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental" title="experimental">experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20model" title=" numerical model"> numerical model</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20loading" title=" lateral loading"> lateral loading</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20efficiency" title=" group efficiency"> group efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=helical%20piles" title=" helical piles"> helical piles</a> </p> <a href="https://publications.waset.org/abstracts/190044/the-impact-of-combined-loading-on-lateral-capacity-and-group-efficiency-of-helical-piles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190044.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">40</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">14483</span> The Pile Group Efficiency for Different Embedment Lengths in Dry Sand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20M.%20Shahin">Mohamed M.

The base resistance of smooth model pile groups in sand under static loading is investigated experimentally in a pile soil test apparatus. Improvement were made to the sand around the piles in order to increase the shaft resistance of the single pile and the pile groups, and also base resistance especially for the central pile in pile groups. The study outlines the behaviour of a single-pile, 4-, 5-, and 9- pile groups arranged in a doubly symmetric [square] layout with different embedment lengths and pile spacing in loose dry sand [normal] and dense dry sand [compacted] around the piles. This study evaluate the variation of the magnitude and the proportion of end bearing capacity of individual piles in different pile groups.

Findings suggest that the influence of particle concentration on the growth performance will reduce with the increase of supersaturation. Reducing residence time and increasing particle concentration have similar effects on the growth performance of the high-concentration particle group. Increasing particle concentration and shortening residence time will increase the critical supersaturation of the particle group.

The experiment was conducted for six weeks using an 8-week old male rat as experiment animals and the experimental design was to use six treatments groups of 4 repetitions using three mice per repetition. The treatment groups were organized into a normal fat diet control (NFC), a high fat (HF) diet control (HFC), a prebiotic 0% treatment (HF+LA+sea tangle 0%, ST0), a prebiotic 5% treatment (HF+LA+sea tangle 5%, ST5), a prebiotic 10% treatment (HF+LA+sea tangle 10%, ST10), and a prebiotic 15% treatment group (HF+LA+sea tangle 15%, ST15) to conduct experiments with various levels of prebiotics. According to the results of the experiment, the NFC group showed the highest daily weight gain (22.34g) and the ST0 group showed the lowest daily weight gain (19.41g). However, weight gains during the entire experimental period were the highest in the HFC group (475.73g) and the lowest in the ST0 group (454.23g). Feed efficiency was the highest in the HFC group (0.20). Treatment with synbiotics composed of LAB and sea tangle suppressed weight increases due to HF diet and reduced feed efficiency. Intestinal microorganisms were identified through pyrosequncing and according to the results, Firmicutes phylum (approximately 60%) and Bacteroidetes phylum (approximately 30%) accounted for approximately 90% or more of intestinal microorganisms in all of the treatment groups indicating these bacteria are dominating in the intestines. Firmicutes that is related to weight increases accounted for 64.96% of microorganisms in the NFC group, 75.32% in the HFC group, 59.51% in the ST0 group, 61.29% in the ST5 group, 49.91% in the ST10 group, and 39.65% in the ST15 group. Therefore, Firmicutes showed the highest share the HFC group that showed high weight gains and the lowest share in the group treated with mixed synbiotics composed of LAB and sea tangle. Bacteroidetes that is related to weight gain inhibition accounted for 32.12% of microorganisms in the NFC group, and HFC group 21.57%, ST0 group 37.66%, ST5 group 34.92%, ST10 group 44.46%, and ST15 group 53.22%. Therefore, the share of Bacteroidetes was the lowest in the HFC group with no addition of synbiotics and increased along with the level of treatment with synbiotics. Changes in blood components were not significantly different among the groups and SCFA yields were shown to be higher in groups treated with synbiotics than in groups not added with synbiotics. Through the present study, it was shown that the supply of synbiotics composed of LAB and sea tangle increased feed intake but led to weight losses and that the intake of synbiotics composed of LAB and sea tangle had anti-obesity effects due to decreases in Firmicutes which are microorganisms related to weight gains and increases in Bacteroidetes which are microorganisms related to weight losses. Therefore, synbiotics composed of LAB and sea tangle are considered to have the effect to prevent metabolic disorders in the rat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteroidetes" title="bacteroidetes">bacteroidetes</a>, <a href="https://publications.waset.org/abstracts/search?q=firmicutes" title=" firmicutes"> firmicutes</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20microbiota" title=" intestinal microbiota"> intestinal microbiota</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid" title=" lactic acid"> lactic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20tangle" title=" sea tangle"> sea tangle</a>, <a href="https://publications.waset.org/abstracts/search?q=synbiotics" title=" synbiotics"> synbiotics</a> </p> <a href="https://publications.waset.org/abstracts/49562/effect-of-synbiotics-on-rats-intestinal-microbiota" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49562.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">14479</span> An Output Oriented Super-Efficiency Model for Considering Time Lag Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanshuang%20Zhang">Yanshuang Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Byungho%20Jeong"> Byungho Jeong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There exists some time lag between the consumption of inputs and the production of outputs. This time lag effect should be considered in calculating efficiency of decision making units (DMU). Recently, a couple of DEA models were developed for considering time lag effect in efficiency evaluation of research activities. However, these models can’t discriminate efficient DMUs because of the nature of basic DEA model in which efficiency scores are limited to ‘1’. This problem can be resolved a super-efficiency model. However, a super efficiency model sometimes causes infeasibility problem.

The dissipation mechanisms considered include: fluid friction modeled by means of the isentropic efficiency of the compressor, heat transfer leakage directly from the hot reservoir to the cold heat reservoir, and constant velocity of the MHD generator. The study demonstrates that power and efficiency vanish at the extremes of both slow and fast operating conditions. These points are demonstrated on power efficiency curves and the locus of efficiency at maximum power and the locus of maximum efficiency. Qualitatively, the considered loss mechanisms have a similar effect on the efficiency at maximum power operation and on maximum efficiency operation, thus these efficiencies are reduced, even for small values of the loss mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamic%20generator" title="magnetohydrodynamic generator">magnetohydrodynamic generator</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20efficiency" title=" electrical efficiency"> electrical efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20power" title=" maximum power"> maximum power</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20efficiency" title=" maximum efficiency"> maximum efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20engine" title=" heat engine"> heat engine</a> </p> <a href="https://publications.waset.org/abstracts/103498/power-efficiency-characteristics-of-magnetohydrodynamic-thermodynamic-gas-cycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103498.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">245</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">14477</span> Fin Efficiency of Helical Fin with Fixed Fin Tip Temperature Boundary Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Richard%20G.%20Carranza">Richard G.

However, group commerce faces some challenging problems. The products or services provided by vendors do not satisfactorily reflect customers’ opinions, so that the sale and revenue of group commerce gradually become lower. On the other hand, the process for a formed customer group to reach group-purchasing consensus is time-consuming and the final decision is not the best choice for each group members. In this paper, we design a social decision support mechanism, by using group discussion message to recommend suitable options for group members and we consider social influence and personal preference to generate option ranking list. The proposed mechanism can enhance the group purchasing decision making efficiently and effectively and venders can provide group products or services according to the group option ranking list. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20network" title="social network">social network</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20decision" title=" group decision"> group decision</a>, <a href="https://publications.waset.org/abstracts/search?q=text%20mining" title=" text mining"> text mining</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20commerce" title=" group commerce"> group commerce</a> </p> <a href="https://publications.waset.org/abstracts/46955/a-social-decision-support-mechanism-for-group-purchasing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46955.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">485</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">14475</span> Effect of Feed Rate on Grinding Circuits and Cyclone Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patel%20Himeshkumar%20Ashokbhai">Patel Himeshkumar Ashokbhai</a>, <a href="https://publications.waset.org/abstracts/search?q=Suchit%20Sharma"> Suchit Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Arvind%20Kumar%20Garg"> Arvind Kumar Garg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to study the effect of change in feed rate on grinding circuit and cyclone efficiency in case of lead-zinc ore. The following experiments and analysis were conducted on beneficiation circuit of Sindesar Khurd (SK) mines under Hindustan Zinc Ltd. subsidiary of Vedanta Group of Companies, a leading producer of lead-Zinc, silver and cadmium (as by products) in India. Feed rate is an important variable in beneficiation circuit operation. Optimizing feed rate is indispensable for any grinding circuit and directly effects cyclone efficiency. The size analysis of ore in grinding circuit along with cyclone efficiency on varying feed rates establishes their interdependence. Feed rate determines retention time ore gets within grinding circuit. Retention time in turn determines degree of liberation of mineral. Inadequate liberation causes decreased circuit efficiency. In this paper we have studied the effect of varying feed rate on (1) D80 particle size of different sections of different streams of grinding circuit (2) Re-circulating load (3) Cyclone efficiency. As a conclusion, this study gives some clues to operate grinding circuits and hydro-cyclones in more efficient way regarding beneficiation of Lead-zinc ore. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyclone%20efficiency" title="cyclone efficiency">cyclone efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20rate" title=" feed rate"> feed rate</a>, <a href="https://publications.waset.org/abstracts/search?q=grinding%20circuit" title=" grinding circuit"> grinding circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=re-circulating%20load" title=" re-circulating load"> re-circulating load</a> </p> <a href="https://publications.waset.org/abstracts/38698/effect-of-feed-rate-on-grinding-circuits-and-cyclone-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38698.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">398</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">14474</span> Experimental Investigations on Group Interaction Effects of Laterally Loaded Piles in Submerged Sand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jasaswini%20Mishra">Jasaswini Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashim%20K.%20Dey"> Ashim K. Dey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to investigate the group interaction effects of laterally loaded pile groups driven into a medium dense sand layer in submerged state. Static lateral load tests were carried out on pile groups consisting of varying number of piles and at different spacings. The test setup consists of a load cell (500 kg capacity) and an LVDT (50 mm) to measure the load and pile head deflection respectively. The piles were extensively instrumented with strain gauges so as to study the variation of soil resistance within the group. The bending moments at various depths were calculated from strain gauge data and these curves were fitted using a higher order polynomial in order to get 'p-y' curves. A comparative study between a single pile and a pile under a group has also been done for a better understanding of the group effect. It is observed that average load per pile is significantly reduced relative to single pile and it decreases with increase in the number of piles in a pile group. The loss of efficiency of the piles in the group, commonly referred to as "shadowing" effect, has been expressed by the use of a 'p-multiplier'. Leading rows carries greater amount of load when compared with the trailing rows. The variations of bending moment with depth for different rows of pile within a group and different spacing have been analyzed and compared with that of a single pile. p multipliers within different rows in a pile group were evaluated from the experimental study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=group%20action" title="group action">group action</a>, <a href="https://publications.waset.org/abstracts/search?q=laterally%20loaded%20piles" title=" laterally loaded piles"> laterally loaded piles</a>, <a href="https://publications.waset.org/abstracts/search?q=p-multiplier" title=" p-multiplier"> p-multiplier</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20gauge" title=" strain gauge"> strain gauge</a> </p> <a href="https://publications.waset.org/abstracts/51258/experimental-investigations-on-group-interaction-effects-of-laterally-loaded-piles-in-submerged-sand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51258.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">242</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">14473</span> Performance of Environmental Efficiency of Energy Consumption in OPEC Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahram%20Fathi">Bahram Fathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Khodaparast%20Mashhadi"> Mahdi Khodaparast Mashhadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masuod%20Homayounifar"> Masuod Homayounifar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global awareness on energy security and climate change has created much interest in assessing energy efficiency performance.

While a significant number of studies in field of stigma suggest that group-identification has positive consequences for stigmatized individuals, ironically very miniscule empirical work in sight has attempted to investigate in-group identification as a coping measure against stigma, humiliation and related experiences among disability group. In view of death of empirical research on in-group identification among disability group, through present work, an attempt has been made to examine the experiences of stigma, humiliation, and in-group identification among disability group. Results of the study suggest that use of in-group identification as a coping strategy is not uniform across members of disability group and degree of in-group identification differs across different sub-groups of disability groups. Further, in-group identification among members of disability group depends on variables like degree and impact of disability, factors like onset of disability, nature, and visibility of disability, educational experiences and resources available to deal with disabling conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disability" title="disability">disability</a>, <a href="https://publications.waset.org/abstracts/search?q=stigma" title=" stigma"> stigma</a>, <a href="https://publications.waset.org/abstracts/search?q=in-group%20identification" title=" in-group identification"> in-group identification</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20identity" title=" social identity"> social identity</a> </p> <a href="https://publications.waset.org/abstracts/48888/disability-stigma-and-in-group-identification-an-exploration-across-different-disability-subgroups" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48888.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">324</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">14471</span> Maximizing the Efficiency of Knowledge Management Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tori%20Reddy%20Dodla">Tori Reddy Dodla</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Ann%20Jones"> Laura Ann Jones</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to propose strategies to improve the efficiency of Knowledge Management Systems (KMS).

This time lag effect should be considered in evaluating the performance of organizations. Recently, a couple of DEA models were developed for considering time lag effect in efficiency evaluation of research activities. Multi-periods input(MpI) and Multi-periods output(MpO) models are integrated models to calculate simple efficiency considering time lag effect. However, these models can’t discriminate efficient DMUs because of the nature of basic DEA model in which efficiency scores are limited to ‘1’. That is, efficient DMUs can’t be discriminated because their efficiency scores are same. Thus, this paper suggests a super-efficiency model for efficiency evaluation under the consideration of time lag effect based on the MpO model. A case example using a long-term research project is given to compare the suggested model with the MpO model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DEA" title="DEA">DEA</a>, <a href="https://publications.waset.org/abstracts/search?q=super-efficiency" title=" super-efficiency"> super-efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20lag" title=" time lag"> time lag</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-periods%20input" title=" multi-periods input"> multi-periods input</a> </p> <a href="https://publications.waset.org/abstracts/13008/a-super-efficiency-model-for-evaluating-efficiency-in-the-presence-of-time-lag-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13008.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">473</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">14469</span> Impact Evaluation and Technical Efficiency in Ethiopia: Correcting for Selectivity Bias in Stochastic Frontier Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tefera%20Kebede%20Leyu">Tefera Kebede Leyu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to estimate the impact of LIVES project participation on the level of technical efficiency of farm households in three regions of Ethiopia. We used household-level data gathered by IRLI between February and April 2014 for the year 2013(retroactive). Data on 1,905 (754 intervention and 1, 151 control groups) sample households were analyzed using STATA software package version 14. Efforts were made to combine stochastic frontier modeling with impact evaluation methodology using the Heckman (1979) two-stage model to deal with possible selectivity bias arising from unobservable characteristics in the stochastic frontier model. Results indicate that farmers in the two groups are not efficient and operate below their potential frontiers i.e., there is a potential to increase crop productivity through efficiency improvements in both groups. In addition, the empirical results revealed selection bias in both groups of farmers confirming the justification for the use of selection bias corrected stochastic frontier model. It was also found that intervention farmers achieved higher technical efficiency scores than the control group of farmers. Furthermore, the selectivity bias-corrected model showed a different technical efficiency score for the intervention farmers while it more or less remained the same for that of control group farmers. However, the control group of farmers shows a higher dispersion as measured by the coefficient of variation compared to the intervention counterparts. Among the explanatory variables, the study found that farmer’s age (proxy to farm experience), land certification, frequency of visit to improved seed center, farmer’s education and row planting are important contributing factors for participation decisions and hence technical efficiency of farmers in the study areas. We recommend that policies targeting the design of development intervention programs in the agricultural sector focus more on providing farmers with on-farm visits by extension workers, provision of credit services, establishment of farmers’ training centers and adoption of modern farm technologies. Finally, we recommend further research to deal with this kind of methodological framework using a panel data set to test whether technical efficiency starts to increase or decrease with the length of time that farmers participate in development programs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impact%20evaluation" title="impact evaluation">impact evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency%20analysis%20and%20selection%20bias" title=" efficiency analysis and selection bias"> efficiency analysis and selection bias</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20frontier%20model" title=" stochastic frontier model"> stochastic frontier model</a>, <a href="https://publications.waset.org/abstracts/search?q=Heckman-two%20step" title=" Heckman-two step"> Heckman-two step</a> </p> <a href="https://publications.waset.org/abstracts/173324/impact-evaluation-and-technical-efficiency-in-ethiopia-correcting-for-selectivity-bias-in-stochastic-frontier-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173324.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">14468</span> Technical Efficiency in Organic and Conventional Wheat Farms: Evidence from a Primary Survey from Two Districts of Ganga River Basin, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Singh">S.

A study on technical efficiency estimation under these farming systems, particularly in the Ganga River Basin, where the promotion of organic farming is incentivized, can help to understand whether the inputs are utilized to their maximum possible level and what measures can be taken to improve the efficiency. This paper, therefore, analyses the technical efficiency of wheat farms operating under organic and conventional farming systems. The study is based on a primary survey of 600 farms (300 organic ad 300 conventional) conducted in 2021 in two districts located in the Middle Ganga River Basin, India. Technical, managerial, and scale efficiencies of individual farms are estimated by applying the data envelopment analysis (DEA) methodology. The per hectare value of wheat production is taken as an output variable, and values of seeds, human labour, machine cost, plant nutrients, farm yard manure (FYM), plant protection, and irrigation charges are considered input variables for estimating the farm-level efficiencies. The post-DEA analysis is conducted using the Tobit regression model to know the efficiency determining factors. The results show that technical efficiency is significantly higher in conventional than organic farming systems due to a higher gap in scale efficiency than managerial efficiency. Further, 9.8% conventional and only 1.0% organic farms are found operating at the most productive scale size (MPSS), and 99% organic and 81% conventional farms at IRS. Organic farms perform well in managerial efficiency, but their technical efficiency is lower than conventional farms, mainly due to their relatively lower scale size. The paper suggests that technical efficiency in organic wheat can be increased by upscaling the farm size by incentivizing group/collective farming in clusters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic" title="organic">organic</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional" title=" conventional"> conventional</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20efficiency" title=" technical efficiency"> technical efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=determinants" title=" determinants"> determinants</a>, <a href="https://publications.waset.org/abstracts/search?q=DEA" title=" DEA"> DEA</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobit%20regression" title=" Tobit regression"> Tobit regression</a> </p> <a href="https://publications.waset.org/abstracts/156593/technical-efficiency-in-organic-and-conventional-wheat-farms-evidence-from-a-primary-survey-from-two-districts-of-ganga-river-basin-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156593.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">99</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">14467</span> Endoscopic Treatment of Patients with Large Bile Duct Stones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Teterin">Yuri Teterin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lomali%20Generdukaev"> Lomali Generdukaev</a>, <a href="https://publications.waset.org/abstracts/search?q=Dmitry%20Blagovestnov"> Dmitry Blagovestnov</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Yartcev"> Peter Yartcev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Under the definition "large biliary stones," we referred to stones over 1.5 cm, in which standard transpapillary litho extraction techniques were unsuccessful.

Sklifosovsky Research Institute of Emergency Care treated 706 patients diagnosed with choledocholithiasis who underwent biliary stones removed from the common bile duct. Of them, in 57 (8, 1%) patients, the use of a Dormia basket or Biliary stone extraction balloon was technically unsuccessful due to the size of the stones (more than 15 mm in diameter), which required their destruction. Mechanical lithotripsy was used in 35 patients, and electrohydraulic and laser lithotripsy under SpyGlass direct visualization system - in 26 patients. Results: The efficiency of mechanical lithotripsy was 72%. Complications in this group were observed in 2 patients. In both cases, on day one after lithotripsy, acute pancreatitis developed, which resolved on day three with conservative therapy (Clavin-Dindo type 2). The efficiency of contact lithotripsy was in 100% of patients. Complications were not observed in this group. Bilirubin level in this group normalized on the 3rd-4th day. Conclusion: Our study showed the efficacy and safety of electrohydraulic and laser lithotripsy under SpyGlass control in a well-defined group of patients with large bile duct stones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20lithotripsy" title="contact lithotripsy">contact lithotripsy</a>, <a href="https://publications.waset.org/abstracts/search?q=choledocholithiasis" title=" choledocholithiasis"> choledocholithiasis</a>, <a href="https://publications.waset.org/abstracts/search?q=SpyGlass" title=" SpyGlass"> SpyGlass</a>, <a href="https://publications.waset.org/abstracts/search?q=cholangioscopy" title=" cholangioscopy"> cholangioscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=laser" title=" laser"> laser</a>, <a href="https://publications.waset.org/abstracts/search?q=electrohydraulic%20system" title=" electrohydraulic system"> electrohydraulic system</a>, <a href="https://publications.waset.org/abstracts/search?q=ERCP" title=" ERCP"> ERCP</a> </p> <a href="https://publications.waset.org/abstracts/159352/endoscopic-treatment-of-patients-with-large-bile-duct-stones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159352.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">80</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">14466</span> A Weighted Group EI Incorporating Role Information for More Representative Group EI Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siyu%20Wang">Siyu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthony%20Ward"> Anthony Ward</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Emotional intelligence (EI) is a well-established personal characteristic. It has been viewed as a critical factor which can influence an individual's academic achievement, ability to work and potential to succeed. When working in a group, EI is fundamentally connected to the group members' interaction and ability to work as a team. The ability of a group member to intelligently perceive and understand own emotions (Intrapersonal EI), to intelligently perceive and understand other members' emotions (Interpersonal EI), and to intelligently perceive and understand emotions between different groups (Cross-boundary EI) can be considered as Group emotional intelligence (Group EI). In this research, a more representative Group EI measurement approach, which incorporates the information of the composition of a group and an individual’s role in that group, is proposed. To demonstrate the claim of being more representative Group EI measurement approach, this study adopts a multi-method research design, involving a combination of both qualitative and quantitative techniques to establish a metric of Group EI. From the results, it can be concluded that by introducing the weight coefficient of each group member on group work into the measurement of Group EI, Group EI will be more representative and more capable of understanding what happens during teamwork than previous approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=case%20study" title="case study">case study</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title=" emotional intelligence"> emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20EI" title=" group EI"> group EI</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-method%20research" title=" multi-method research"> multi-method research</a> </p> <a href="https://publications.waset.org/abstracts/101666/a-weighted-group-ei-incorporating-role-information-for-more-representative-group-ei-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101666.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">125</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">14465</span> On the Efficiency of a Double-Cone Gravitational Motor and Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barenten%20Suciu">Barenten Suciu</a>, <a href="https://publications.waset.org/abstracts/search?q=Akio%20Miyamura"> Akio Miyamura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, following the study-case of an inclined plane gravitational machine, efficiency of a double-cone gravitational motor and generator is evaluated. Two types of efficiency ratios, called <em>translational efficiency</em> and <em>rotational efficiency</em>, are defined relative to the intended duty of the gravitational machine, which can be either the production of translational kinetic energy, or rotational kinetic energy. One proved that, for pure rolling movement of the double- cone, in the absence of rolling friction, the total mechanical energy is conserved. In such circumstances, as the motion of the double-cone progresses along rails, the translational efficiency decreases and the rotational efficiency increases, in such way that sum of the rotational and translational efficiencies remains unchanged and equal to 1. Results obtained allow a comparison of the gravitational machine with other types of motor-generators, in terms of the achievable efficiency. <p class="card-text"><strong>Keywords:</strong> <a
