Surgery is the ideal treatment as it eliminates soilage of peritoneal cavity in an effort to lessen the toxaemia and enhance the recovery of the patient. However, there is no uniformity of standardized operative procedure that is most effective for management. Material and method: The study was conducted on 66 patients of perforation peritonitis from November 2013 to February 2015 in Lok Nayak Hospital. Data of each patient were recorded on a pre-determined proforma. The methods used for repair were Primary repair, Resection anastomosis (RA) and Ileostomy. Result: Male preponderance was noticed among the patients with majority in their third decade. Of all perforations 40.9% were tubercular and 34.8% were typhoid. Amongst operated cases 27.3% underwent primary repair, RA was performed in 45.5%, Ileostomy in 27.3%patients. The average time taken for RA and ileostomy was more than primary repair. The type of repair bear no significance to size or no of perforation but was significant statistically for distance from I/C valve(P=.005) and edema of bowel wall(p=.002) when analysed for post op complications. Wound infection, dehiscence, intra-abdominal collections were complications observed bearing no significance to type of repair. Ileostomy per se has its own complications peristomal skin excoriation seen in 83.3%, electrolyte imbalance in 33.3%, duration for closure averaged 188 days (median 150 days, range 85-400 days). Conclusion: Primary closure is preferable in patients with single, small perforations. RA is advocated in patients with multiple or large perforation, perforation proximal to stricture. Ileostomy should not be considered as primary definitive procedure and reserved only for moribund patients as a lifesaving procedure. It has more morbidity and requires a second surgery for closure increasing the cost of treatment as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ileal%20perforation" title="ileal perforation">ileal perforation</a>, <a href="https://publications.waset.org/abstracts/search?q=ileostomy" title=" ileostomy"> ileostomy</a>, <a href="https://publications.waset.org/abstracts/search?q=perforation%20peritonitis" title=" perforation peritonitis"> perforation peritonitis</a>, <a href="https://publications.waset.org/abstracts/search?q=typhoid%20perforation%20management" title=" typhoid perforation management "> typhoid perforation management </a> </p> <a href="https://publications.waset.org/abstracts/42786/outcome-analysis-of-various-management-strategies-for-ileal-perforation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42786.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">252</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">72</span> Effects of Palm Kernel Expeller Processing on the Ileal Populations of Lactobacilli and Escherichia Coli in Broiler Chickens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Navidshad">B.

At the finisher phase, one hundred male broiler chickens (Cobb-500) were fed a control diet or the diets containing 200 g/kg of normal PKE (70 g/kg shell), low shell PKE (30 g/kg shell), enzymatic treated PKE or low shell-enzymatic treated PKE. The quantitative real-time PCR were used to determine the ileal bacteria populations. The lowest ileal Lactobacilli population was found in the chickens fed the low shell PKE diet. Dietary normal PKE or low shell-enzymatic treated PKE decreased the Escherichia coli population compared to the control diet. The results suggested that PKE could be included up to 200 g/kg in the finisher diet, however, any screening practice to reduce the shell content of PKE without enzymatic degradation of β-mannan, decrease ileal Lactobacilli population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20kernel%20expeller" title="palm kernel expeller">palm kernel expeller</a>, <a href="https://publications.waset.org/abstracts/search?q=exogenous%20enzyme" title=" exogenous enzyme"> exogenous enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=shell%20content" title=" shell content"> shell content</a>, <a href="https://publications.waset.org/abstracts/search?q=ileum%20bacteria" title=" ileum bacteria"> ileum bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=broiler%20chickens" title=" broiler chickens"> broiler chickens</a> </p> <a href="https://publications.waset.org/abstracts/33444/effects-of-palm-kernel-expeller-processing-on-the-ileal-populations-of-lactobacilli-and-escherichia-coli-in-broiler-chickens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33444.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">71</span> Evaluation of the Spectrum of Cases of Perforation Peritonitis at Jawaharlal Nehru Medical College, Aligarh Muslim University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mujahid%20Ali">Mujahid Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Wasif%20Mohammed%20Ali"> Wasif Mohammed Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Meraj%20Ahmad"> Meraj Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Perforation peritonitis is the most common surgical emergency encountered by surgeons all over the world as well as in India. The etiology of perforation peritonitis in India continues to be different from its western counterparts. The aim of this study is to evaluate the spectrum of cases of perforation peritonitis at our hospital. Methods: A prospective study conducted includes three hundred thirtysix patients of perforation peritonitis at J. N. Medical College from October 2015 to July 2017. The patients were admitted, resuscitated and underwent emergency laparotomy. Data were collected in terms of demographic profile, clinical presentations, site of perforations, causes and surgical outcomes. Results: In this study, the most common cause of perforation peritonitis was peptic ulcer disease (43%), followed by enteric perforation (12.8%), tubercular perforation (12.5%), traumatic perforation (11.9%), appendicular perforation (9.8%), amoebic caecal perforation (3%), malignant perforation (1.5%), etc. The sites of perforations were stomach in majority (38.3%), ileum (31%), appendix (8%), duodenum (5.%), caecum (4.4%) ,colon (3%), jejunum (8.5%) and gall bladder (2%). The overall mortality was 21% in our study. Age >50 years (p= <0.0001, OR= 3.9260, CI= 2.2 to 6.9), organ failure (p= <0.0001, OR= 29.2, CI= 14.8 to 57.6), shock (p=<0.0001, OR=20.20, CI= 10.56 to 38.6), diffuse peritonitis (p<0.0015, OR= 6.8810, CI= 2.09 to 22.57) and faecal exudates (p<0.0001) were found to be significant factors affecting mortality. The most common complication associated was superficial wound infection (40%), followed by burst abdomen seen in 21% cases, intra-abdominal sepsis in 18% cases, electrolyte imbalances in 15% cases, anastomotic leak in 6% cases. Conclusion: In this study, stomach is the most common site of perforation with peptic ulcer disease being the most common etiology. Older age, presence of shock, organ failure and faecal peritonitis were the risk factors affecting the mortality of the patients. Early recognition, adequate resuscitation and referral of patients can influence outcome and reduces mortality as well as morbidity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=etiology" title="etiology">etiology</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=perforation" title=" perforation"> perforation</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum" title=" spectrum"> spectrum</a> </p> <a href="https://publications.waset.org/abstracts/78122/evaluation-of-the-spectrum-of-cases-of-perforation-peritonitis-at-jawaharlal-nehru-medical-college-aligarh-muslim-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78122.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">257</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">70</span> Thermal Performance of Plate-Fin Heat Sink with Lateral Perforation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sakkarin%20Chingulpitak">Sakkarin Chingulpitak</a>, <a href="https://publications.waset.org/abstracts/search?q=Somchai%20Wongwises"> Somchai Wongwises</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the past several decades, the development of electronic devices has led to higher performance. Therefore, an electronic cooling system is important for the electronic device. A heat sink which is a part of the electronic cooling system is continuously studied in the research field to enhance the heat transfer. To author’s best knowledge, there have been only a few articles which reported the thermal performance of plate-fin heat sink with perforation. This research aims to study on the flow and heat transfer characteristics of the solid-fin heat sink (SFHS) and laterally perforated plate-fin heat sink (LAP-PFHS). The SFHS and LAP-PFHSs are investigated on the same fin dimensions. The LAP-PFHSs are performed with a 27 perforation number and two different diameters of circular perforation (3 mm and 5 mm). The experimental study is conducted under various Reynolds numbers from 900 to 2,000 and the heat input of 50W. The experimental results show that the LAP-PFHS with perforation diameter of 5 mm gives the minimum thermal resistance about 25% lower than SFHS. The thermal performance factor which takes into account the ratio of the Nusselt number and ratio of friction factor is used to find the suitable design parameters. The experimental results show that the LAP-PFHS with the perforation diameter of 3 mm provides the thermal performance of 15% greater than SFHS. In addition, the simulation study is presented to investigate the effect of the air flow behavior inside the perforation on the thermal performance of LAP-PFHS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20sink" title="heat sink">heat sink</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20flow" title=" parallel flow"> parallel flow</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20perforation" title=" circular perforation"> circular perforation</a>, <a href="https://publications.waset.org/abstracts/search?q=non-bypass%20flow" title=" non-bypass flow"> non-bypass flow</a> </p> <a href="https://publications.waset.org/abstracts/105150/thermal-performance-of-plate-fin-heat-sink-with-lateral-perforation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105150.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">148</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">69</span> Effect of Microencapsulated Butyric Acid Supplementation on Growth Performance, Ileal Digestibility of Protein, Gut Health and Immunity in Broilers </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ahmed">Saeed Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Imran"> Muhammad Imran</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasir%20Allah%20Ditta"> Yasir Allah Ditta</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahid%20Mehmood"> Shahid Mehmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Rasool"> Zahid Rasool</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A study was conducted to investigate the effect of different levels of microencapsulated butyric (MEB) on growth performance, gut health and immunity in commercial broiler chickens.

Though esophageal perforation is a rare complication of these instrumentations, its prevalence is highest in extremely premature neonates. Due to its association with significant morbidity (including respiratory deterioration, pneumothorax, and sepsis) and even mortality, it is an important issue to prevent this iatrogenic complication in the field of premature care. We demonstrate an esophageal perforation in an extreme-low-birth-weight neonate after oro-gastric tube placement. This female baby weighing 680 grams was delivered by caesarean section at 25 weeks of gestational age. She initially received oro-tracheal intubation with mechanical ventilation which was smoothly weaned to non-invasive positive-pressure ventilation at 7-day-old. However, after insertion of a 5-French oro-gastric tube, the baby’s condition suddenly worsened with apnea requiring mechanical ventilation. Her chest radiogram showed the oro-gastric tube in right pleural space, and thus another oro-gastric tube was replaced, and its position was radiographically confirmed. The malpositioned tube was then removed. The baby received 2-week course of intravenous antibiotics for her esophageal perforation. Feeding was then reintroduced and increased to full feeds in a smooth course. She was discharged at 107-day-old. Esophageal perforation in newborn is very rare. Sudden respiratory deterioration in a neonate after naso-/oro-gastric tube placement should alarm us to consider esophageal perforation, and further radiological investigation is required for the diagnosis. Tube materials, patient condition, and age are major risk factors of esophageal perforation. The use of softer tube material, such as silicone, in extreme premature baby might prevent this fetal complication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esophageal%20perforation" title="esophageal perforation">esophageal perforation</a>, <a href="https://publications.waset.org/abstracts/search?q=preterm" title=" preterm"> preterm</a>, <a href="https://publications.waset.org/abstracts/search?q=newborn" title=" newborn"> newborn</a>, <a href="https://publications.waset.org/abstracts/search?q=feeding%20tube" title=" feeding tube"> feeding tube</a> </p> <a href="https://publications.waset.org/abstracts/50256/a-case-of-iatrogenic-esophageal-perforation-in-an-extremely-low-birth-weight-neonate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50256.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">271</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">66</span> The Source of Fibre and Roxazyme® G2 Interacted to Influence the Length of Villi in the Ileal Epithelium of Growing Pigs Fed Fibrous Maize-Soybean Diets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Fushai">F.

The control was a standard, low fibre (141 g total dietary fibre kg-1 dry matter) diet formulated from dehulled soybean (Glycine max), maize (Zea Mays) meal and hominy chop. Five fibrous diets were evaluated in which fibre was increased by partial substitution of the grains in the control diet with maize cobs, soybean hulls, barley (Hordeum vulgare L) brewer’s grains, Lucerne (Medicago sativa) hay or wheat (Triticum aestivum) bran. Each diet was duplicated and 220 mg Roxazyme® G2 kg-1 dry mater was added to one of the mixtures. Seventy-two intact Large White X Landrace male pigs of weight 32 ± 5.6 kg pigs were randomly allocated to the diets in a complete randomised design with a 2 (fibre source) X (enzyme) factorial arrangement of treatments. The pigs were fed ad libitum for 10 weeks. Ileal tissue samples were taken at slaughter, at a point 50cm above the ileal-caecal valve. Villi length and area, and crypt depth were measured by computerised image analyses. The villi length: crypt ratio was calculated. The diet and the supplemental enzyme cocktail did not affect (p>0.05) any of the measured parameters. Significant (p=0.016) diet X enzyme interaction was observed for villi length whereby the enzyme reduced the villi length of pigs on the soy-hulls, standard and wheat bran diets, with an opposite effect on pigs on the maize cob, brewer’s grain, Lucerne diets. The results suggested fibre-source dependent changes in the morphology of the ileal epithelium of pigs fed high fibre, maize-soybean diets fortified with Roxazyme® G2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fibre" title="fibre">fibre</a>, <a href="https://publications.waset.org/abstracts/search?q=growing%20pigs" title=" growing pigs"> growing pigs</a>, <a href="https://publications.waset.org/abstracts/search?q=histomorphology" title=" histomorphology"> histomorphology</a>, <a href="https://publications.waset.org/abstracts/search?q=ileum" title=" ileum"> ileum</a>, <a href="https://publications.waset.org/abstracts/search?q=Roxazyme%C2%AE%20G2" title=" Roxazyme® G2"> Roxazyme® G2</a> </p> <a href="https://publications.waset.org/abstracts/33887/the-source-of-fibre-and-roxazyme-g2-interacted-to-influence-the-length-of-villi-in-the-ileal-epithelium-of-growing-pigs-fed-fibrous-maize-soybean-diets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33887.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">469</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">65</span> Air Flows along Perforated Metal Plates with the Heat Transfer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karel%20Frana">Karel Frana</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylvio%20Simon"> Sylvio Simon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of the paper is a numerical study of heat transfer between perforated metal plates and the surrounding air flows. Different perforation structures can nowadays be found in various industrial products. Besides improving the mechanical properties, the perforations can intensify the heat transfer as well. The heat transfer coefficient depends on a wide range of parameters such as type of perforation, size, shape, flow properties of the surrounding air etc. The paper was focused on three different perforation structures which have been investigated from the point of the view of the production in the previous studies. To determine the heat coefficients and the Nusselt numbers, the numerical simulation approach was adopted. The calculations were performed using the OpenFOAM software. The three-dimensional, unstable, turbulent and incompressible air flow around the perforated surface metal plate was considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perforations" title="perforations">perforations</a>, <a href="https://publications.waset.org/abstracts/search?q=convective%20heat%20transfers" title=" convective heat transfers"> convective heat transfers</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flows" title=" turbulent flows"> turbulent flows</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulations" title=" numerical simulations"> numerical simulations</a> </p> <a href="https://publications.waset.org/abstracts/35110/air-flows-along-perforated-metal-plates-with-the-heat-transfer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35110.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">580</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">64</span> Perforation Analysis of the Aluminum Alloy Sheets Subjected to High Rate of Loading and Heated Using Thermal Chamber: Experimental and Numerical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bendarma">A.

The impact problems (penetration and perforation) of the metallic plates have been of interest for a long time. Experimental, analytical as well as numerical studies have been carried out to analyze in details the perforation process. Based on these approaches, the ballistic properties of the material have been studied. The initial and residual velocities laser sensor is used during experiments to obtain the ballistic curve and the ballistic limit. The energy balance is also reported together with the energy absorbed by the aluminum including the ballistic curve and ballistic limit. The high speed camera helps to estimate the failure time and to calculate the impact force. A wide range of initial impact velocities from 40 up to 180 m/s has been covered during the tests. The mass of the conical nose shaped projectile is 28 g, its diameter is 12 mm, and the thickness of the aluminum sheet is equal to 1.0 mm. The ABAQUS/Explicit finite element code has been used to simulate the perforation processes. The comparison of the ballistic curve was obtained numerically and was verified experimentally, and the failure patterns are presented using the optimal mesh densities which provide the stability of the results. A good agreement of the numerical and experimental results is observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloy" title="aluminum alloy">aluminum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=ballistic%20behavior" title=" ballistic behavior"> ballistic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20criterion" title=" failure criterion"> failure criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/60677/perforation-analysis-of-the-aluminum-alloy-sheets-subjected-to-high-rate-of-loading-and-heated-using-thermal-chamber-experimental-and-numerical-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60677.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">312</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">63</span> A Simple Technique for Centralisation of Distal Femoral Nail to Avoid Anterior Femoral Impingement and Perforation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Panwalkar">P.

Mofidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Anterior femoral perforation or distal anterior nail position is a known complication of femoral nailing specifically in pertrochantric fractures fixed with cephalomedullary nail. This has been attributed to wrong entry point for the femoral nail, nail with large radius of curvature or malreduced fracture. Left alone anterior perforation of femur or abutment of nail on anterior femur will result in pain and risk stress riser at distal femur and periprosthetic fracture. There have been multiple techniques described to avert or correct this problem ranging from using different nail, entry point change, poller screw to deflect the nail position, use of shorter nail or use of curved guidewire or change of nail to ensure a nail with large radius of curvature Methods: We present this technique which we have used in order to centralise the femoral nail either when the nail has been put anteriorly or when the guide wire has been inserted too anteriorly prior to the insertion of the nail. This technique requires the use of femoral reduction spool from the nailing set. This technique was used by eight trainees of different level of experience under supervision. Results: This technique was easily reproducible without any learning curve without a need for opening of fracture site or change in the entry point with three different femoral nailing sets in twenty-five cases. The process took less than 10 minutes even when revising a malpositioned femoral nail. Conclusion: Our technique of using femoral reduction spool is easily reproducible and repeatable technique for avoidance of non-centralised femoral nail insertion and distal anterior perforation of femoral nail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=femoral%20fracture" title="femoral fracture">femoral fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=nailing" title=" nailing"> nailing</a>, <a href="https://publications.waset.org/abstracts/search?q=malposition" title=" malposition"> malposition</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/146872/a-simple-technique-for-centralisation-of-distal-femoral-nail-to-avoid-anterior-femoral-impingement-and-perforation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146872.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">141</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">62</span> Deep Neck Infection Associated with Peritoneal Sepsis: A Rare Death Case</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sait%20Ozsoy">Sait Ozsoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Asude%20Gokmen"> Asude Gokmen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehtap%20Yondem"> Mehtap Yondem</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanife%20A.%20Alkan"> Hanife A.

Regeneration of cementum is very essential for the perforation repair. The aim of this study was to investigate the role of Hertwig's epithelial root sheath (HERS) cells on the cementogenic differentiation of stem cells derived from human exfoliated deciduous teeth (SHED) in the presence of chitosan scaffold-TGFβ1. HERS cells were isolated and characterized then co-cultured with SHED with/without chitosan scaffold-TGFβ1. SHED proliferation was assessed by PrestoBlue. Alkaline phosphatase activity, mineralization behaviour and gene/protein expression of cemento/osteoblast phenotype of SHED were evaluated. Results of the present study showed that HERS cells in association with chitosan-TGFβ1 enhanced proliferation and cemento/osteogenic differentiation of SHED. Our novel co-culture system confirmed the potential effect of HERS cells to stimulate the differentiation of SHED along the cementoblastic lineage which was triggered in the presence of chitosan-TGFβ1. This approach possesses a novel therapeutic strategy for future endodontic perforation and periodontitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cementogenesis" title="cementogenesis">cementogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=co-culture%20system" title=" co-culture system"> co-culture system</a>, <a href="https://publications.waset.org/abstracts/search?q=HERS" title=" HERS"> HERS</a>, <a href="https://publications.waset.org/abstracts/search?q=SHED" title=" SHED"> SHED</a> </p> <a href="https://publications.waset.org/abstracts/34836/a-novel-co-culture-system-for-the-cementoblastic-differentiation-of-shed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34836.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">542</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">60</span> Investigation of Enhanced Geothermal System with CO2 as Working Fluid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruina%20Xu">Ruina Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Peixue%20Jiang"> Peixue Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Luo"> Feng Luo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The novel concept of enhanced geothermal system with CO2 instead of water as working fluid (CO2-EGS) has attracted wide attention due to additional benefit of CO2 geological storage during the power generation process.

Three different reservoir inlet and outlet boundary conditions are used in simulations since the well constrains are different in reality. The results show that CO2-EGS system performance of power generation and power cost vary greatly among cases of different wells perforation locations, and the optimum options under different boundary conditions are also different. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enhanced%20Geothermal%20System" title="Enhanced Geothermal System">Enhanced Geothermal System</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20CO2" title=" supercritical CO2"> supercritical CO2</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2-EGS" title=" CO2-EGS"> CO2-EGS</a> </p> <a href="https://publications.waset.org/abstracts/2713/investigation-of-enhanced-geothermal-system-with-co2-as-working-fluid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2713.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">292</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">59</span> Endoscopic Treatment of Esophageal Injuries Using Vacuum Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murad%20Gasanov">Murad Gasanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Shagen%20Danielyan"> Shagen Danielyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Gasanov"> Ali Gasanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Teterin"> Yuri Teterin</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Yartsev"> Peter Yartsev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Despite the advances made in modern surgery, the treatment of patients with esophageal injuries remains one of the most topical and complex issues. In recent years, high-technology minimally invasive methods, such as endoscopic vacuum therapy (EVT) in the treatment of esophageal injuries. The effectiveness of EVT has been sufficiently studied in case of failure of esophageal anastomoses, however the application of this method in case of mechanical esophageal injuries is limited by a small series of observations, indicating the necessity of additional study. Aim: The aim was to аnalyzed of own experience in the use of endoscopic vacuum therapy (EVT) in a comprehensive examination of patients with esophageal injuries. Methods: We analyzed the results of treatment of 24 patients with mechanical injuries of the esophagus for the period 2019-2021. Complex treatment of patients included the use of minimally invasive technologies, including percutaneous endoscopic gastrostomy (PEG), EVT and video-assisted thoracoscopic debridement. Evaluation of the effectiveness of treatment was carried out using multislice computed tomography (MSCT), endoscopy and laboratory tests. The duration of inpatient treatment and the duration of EVT, the number of system replacements, complications and mortality were taken into account. Result: EVT in patients with mechanical injuries of the esophagus allowed to achieve epithelialization of the esophageal defect in 21 patients (87.5%) in the form of linear scar on the site of perforation or pseudodiverticulum. Complications were noted in 4 patients (16.6%), including bleeding (2) and and esophageal stenosis in the perforation area (2). Lethal outcome was in one observation (4.2%). Conclusion. EVT may be the method of choice in complex treatment in patients with esophageal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esophagus%20injuries" title="esophagus injuries">esophagus injuries</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20to%20the%20esophagus" title=" damage to the esophagus"> damage to the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=perforation%20of%20the%20esophagus" title=" perforation of the esophagus"> perforation of the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=spontaneous%20perforation%20of%20the%20esophagus" title=" spontaneous perforation of the esophagus"> spontaneous perforation of the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=mediastinitis" title=" mediastinitis"> mediastinitis</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20vacuum%20therapy" title=" endoscopic vacuum therapy"> endoscopic vacuum therapy</a> </p> <a href="https://publications.waset.org/abstracts/159374/endoscopic-treatment-of-esophageal-injuries-using-vacuum-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159374.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">105</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">58</span> Effect of Bacillus subtilis Pb6 on Growth and Gut Microflora in Clostridium perfringens Challenged Broilers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Khalique">A.

The latter techniques differ from the former in that cap strings allow for liquid to be unloaded continuously, whereas foamer batches require that periodic batching be conducted for the liquid to be unloaded. Although batch injection allows for liquid to be unloaded in wells with suitable water to gas (WGR) ratio and condensate to gas (CGR) ratio without well intervention for capillary string installation, this technique comes with its own set of challenges - for foamer to de-liquify liquids, the chemical needs to reach perforation locations where gas bubbling is observed. In highly scaled perforation zones in certain wells, foamer delivered in batches is unable to reach the gas bubbling zone, thus achieving poor lift efficiency. This paper aims to discuss the techniques and challenges for unloading liquid via batch injection in scaled perforation wells X and Y, whose WGR is 6bbl/MMscf, whose scale build-up is observed at the bottom of perforation interval, whose water column is 400 feet, and whose ‘bubbling zone’ is less than 100 feet. Variables such as foamer Z dosage, batching technique, and well flow control valve opening times are manipulated during the duration of the trial to achieve maximum liquid unloading and gas rates. During the field trial, the team has found optimal values between the three aforementioned parameters for best unloading results, in which each cycle’s gas and liquid rates are compared with baselines with similar flowing tubing head pressures (FTHP). It is discovered that amongst other factors, a good agitation technique is a primary determinant for efficient liquid unloading. An average increment of 2MMscf/d against an average production of 4MMscf/d at stable FTHP is recorded during the trial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foam" title="foam">foam</a>, <a href="https://publications.waset.org/abstracts/search?q=foamer" title=" foamer"> foamer</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20lift" title=" gas lift"> gas lift</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20unloading" title=" liquid unloading"> liquid unloading</a>, <a href="https://publications.waset.org/abstracts/search?q=scale" title=" scale"> scale</a>, <a href="https://publications.waset.org/abstracts/search?q=batch%20injection" title=" batch injection"> batch injection</a> </p> <a href="https://publications.waset.org/abstracts/137524/liquid-unloading-of-wells-with-scaled-perforation-via-batch-foamers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137524.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">184</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">56</span> The Side Effect of the Perforation Shape towards Behaviour Flexural in Castellated Beam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harrys%20Purnama">Harrys Purnama</a>, <a href="https://publications.waset.org/abstracts/search?q=Wardatul%20Jannah"> Wardatul Jannah</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizkia%20Nita%20Hawari"> Rizkia Nita Hawari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the development of the times, there are many materials used to plan a building structure. Steel became one of the most widely used materials in building construction that works as the main structure. Steel Castellated Beam is a type of innovation in the use of steel in building construction. Steel Castellated Beam is a beam that used for long span construction (more than 10 meters). The Castellated Beam is two steel profiles that unified into one to get the appropriate profile height (more than 10 meters). The profile is perforated to minimize the profile's weight, increase the rate, save costs, and have architectural value. The perforations shape in the Castellated Beam can be circular, elliptical, hexagonal, and rectangular. The Castellated beam has a height (h) almost 50% higher than the initial profile thus increasing the axial bending value and the moment of inertia (Iₓ). In this analysis, there are 3 specimens were used with 12.1 meters span of Castellated Beam as the sample with varied perforation, such us round, hexagon, and octagon. Castellated Beam testing system is done with computer-based applications that named Staad Pro V8i. It is to provide a central load in the middle of the steel beam span. It aims to determine the effect of perforation on bending behavior on the steel Castellated Beam by applying some form of perforations on the steel Castellated Beam with test specimen WF 200.100.5.5.8. From the analysis, results found the behavior of steel Castellated Beam when receiving such central load. From the results of the analysis will be obtained the amount of load, shear, strain, and Δ (deflection). The result of analysis by using Staad Pro V8i shows that with the different form of perforations on the profile of Castellated steel, then we get the different tendency of inertia moment. From the analysis, results obtained the moment of the greatest inertia can increase the stiffness of Castellated steel. By increasing the stiffness of the steel Castellated Beam the deflection will be smaller, so it can withstand the moment and a large strength. The results of the analysis show that the most effective and efficient perforations are the steel beam with a hexagon perforation shape. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Castellated%20Beam" title="Castellated Beam">Castellated Beam</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20moment%20of%20inertia" title=" the moment of inertia"> the moment of inertia</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=deflection" title=" deflection"> deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20test" title=" bending test"> bending test</a> </p> <a href="https://publications.waset.org/abstracts/90019/the-side-effect-of-the-perforation-shape-towards-behaviour-flexural-in-castellated-beam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90019.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">168</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">55</span> Stomach Perforation, due to Chronic External Pressure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angelis%20P.%20Barlampas">Angelis P.

MATERIAL: A patient presented to the emergency department due to the sudden onset of continuous abdominal pain, during the last hour and with the clinical symptoms of an acute abdomen. During the clinical examination, signs of peritoneal irritation and diffuse abdominal tenderness were found. The rest of the clinical and laboratory tests did not reveal anything important. From the reported medical history, nothing of note was found, except for the report of a large liver cyst, for which he was advised not to take any further action, except from regular ultrasound examination . METHOD: A computed tomography examination was performed after per os administration of gastrografin, which revealed a hyperdense ascitic effusion, similar in density to that of gastrografin within the intestinal tract. The presence of a large cyst of the left hepatic lobe was confirmed, contacting and pushing against the stomach. In the area of the contact between the liver cyst and the pylorus, there were extraluminal air bubbles and local opacity of the peritoneal fat, with a small hyperdense effusion. Result : The above, as well as the absence of a history of stomach ulcer or recent trauma, or other pathology, argue in favor of acute pyloric perforation, due to mural necrosis, in response to chronic external pressure from the pre-existing large liver cyst. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perforation" title="perforation">perforation</a>, <a href="https://publications.waset.org/abstracts/search?q=stomach" title=" stomach"> stomach</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20liver%20cyst" title=" large liver cyst"> large liver cyst</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20abdomen" title=" CT abdomen"> CT abdomen</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20abdominal%20pain" title=" acute abdominal pain"> acute abdominal pain</a>, <a href="https://publications.waset.org/abstracts/search?q=intraperitoneal%20leakage" title=" intraperitoneal leakage"> intraperitoneal leakage</a>, <a href="https://publications.waset.org/abstracts/search?q=constrast%20leakage" title=" constrast leakage"> constrast leakage</a> </p> <a href="https://publications.waset.org/abstracts/170426/stomach-perforation-due-to-chronic-external-pressure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170426.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">96</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">54</span> Thermal Performance of Radial Heat Sinks for LED Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jongchul%20Park">Jongchul Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Chan%20Byon"> Chan Byon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the thermal performance of radial heat sinks for LED applications is investigated numerically and experimentally. The effect of geometrical parameters such as inner radius, fin height, fin length, and fin spacing, as well as the Elenbaas number, is considered. In addition, the effects of augmentation of concentric ring, perforation, and duct are extensively explored in order to enhance the thermal performance of conventional radial heat sink. The results indicate that the Elenbaas number and the fin radius have a significant effect on the thermal performance of the heat sink. The concentric ring affects the performance much, but the degree of affection is highly dependent on the orientation. The perforation always brings about higher thermal performance. The duct can effectively prevent the bypass of the natural convection flow, which in turn reduces the thermal resistance of the radial heat sink significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title="heat transfer">heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20heat%20sink" title=" radial heat sink"> radial heat sink</a>, <a href="https://publications.waset.org/abstracts/search?q=LED" title=" LED"> LED</a>, <a href="https://publications.waset.org/abstracts/search?q=Elenbaas" title=" Elenbaas"> Elenbaas</a> </p> <a href="https://publications.waset.org/abstracts/36553/thermal-performance-of-radial-heat-sinks-for-led-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36553.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">404</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">53</span> The Value of Routine Terminal Ileal Biopsies for the Investigation of Diarrhea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swati%20%20Bhasin">Swati Bhasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ahmed"> Ali Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Valence%20Xavier"> Valence Xavier</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Liu"> Ben Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aims: Diarrhea is a problem that is a frequent clinic referral to the gastroenterology and surgical team from the General practitioner. To establish a diagnosis, these patients undergo colonoscopy. The current practice at our district general hospital is to perform random left and right colonic biopsies. National guidelines issued by the British Society of Gastroenterology advise all patients presenting with chronic diarrhea should have an Ileoscopy as an indicator for colonoscopy completion. Our primary aim was to check if Terminal ileum (TI) biopsy is required to establish a diagnosis of inflammatory bowel disease (IBD). Methods: Data was collected retrospectively from November 2018 to November 2019. The target population were patients who underwent colonoscopies for diarrhea. Demographic data, endoscopic and histology findings of TI were assessed and analyzed. Results: 140 patients with a mean age of 57 years (19-84) underwent a colonoscopy (M: F; 1:2.3). 92 patients had random colonic biopsies taken and based on the histological results of these, 15 patients (16%) were diagnosed with IBD. The TI was successfully intubated in 40 patients, of which 32 patients had colonic biopsies taken as well. 8 patients did not have a colonic biopsy taken. Macroscopic abnormality in the TI was detected in 5 patients, all of whom were biopsied. Based on histological results of the biopsy, 3 patients (12%) were diagnosed with IBD. These 3 patients (100%) also had colonic biopsies taken simultaneously and showed inflammation. None of the patients had a diagnosis of IBD confirmed on TI intubation alone (where colonic biopsies were not done). None of the patients has a diagnosis of IBD confirmed on TI intubation alone (where colonic biopsies were negative). Conclusion: TI intubation is a highly-skilled, time-consuming procedure with a higher risk of perforation, which as per our study, has little additional diagnostic value in finding IBD for symptoms of diarrhea if colonic biopsies are taken. We propose that diarrhea is a colonic symptom; therefore, colonic biopsies are positive for inflammation if the diarrhea is secondary to IBD. We conclude that all of the IBDs can be diagnosed simply with colonic biopsies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopsy" title="biopsy">biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=colon" title=" colon"> colon</a>, <a href="https://publications.waset.org/abstracts/search?q=IBD" title=" IBD"> IBD</a>, <a href="https://publications.waset.org/abstracts/search?q=terminal%20ileum" title=" terminal ileum"> terminal ileum</a> </p> <a href="https://publications.waset.org/abstracts/131592/the-value-of-routine-terminal-ileal-biopsies-for-the-investigation-of-diarrhea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131592.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">122</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">52</span> Electromagnetic Simulation of Underground Cable Perforation by Nail </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Nour%20El%20Islam%20Ayad">Ahmed Nour El Islam Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahar%20Rouibah"> Tahar Rouibah</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Krika"> Wafa Krika</a>, <a href="https://publications.waset.org/abstracts/search?q=Houari%20Boudjella"> Houari Boudjella</a>, <a href="https://publications.waset.org/abstracts/search?q=Larab%20Moulay"> Larab Moulay</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Benhamida"> Farid Benhamida</a>, <a href="https://publications.waset.org/abstracts/search?q=Selma%20Benmoussa"> Selma Benmoussa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to evaluate the electromagnetic field of an underground cable of very high voltage perforated by nail.

We describe a case of a 62-year-old male with large bowel obstruction and CT demonstrating dilated large bowels from caecum to proximal sigmoid colon with pneumoperitoneum. Intra-operatively, closed-loop obstruction caused by dense adherence of sigmoid colon to caecum was noted, which had resulted in caecal perforation. Histopathology study indicated primary appendiceal malignancy of signet cell morphology with intra-peritoneal spread to the sigmoid colon. Large bowel obstruction from appendiceal malignancy has rarely been reported, and a similar presentation has not been described in the existing literature. When left-sided large bowel obstruction is suspected to be caused by a malignant stricture, it is essential to consider transperitoneal spread of appendiceal malignancy as potential aetiology, particularly in the elderly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=appendiceal%20carcinoma" title="appendiceal carcinoma">appendiceal carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20bowel%20obstruction" title=" large bowel obstruction"> large bowel obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=signet%20ring%20cell%20cancer" title=" signet ring cell cancer"> signet ring cell cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=caecal%20perforation" title=" caecal perforation"> caecal perforation</a> </p> <a href="https://publications.waset.org/abstracts/141362/closed-loop-large-bowel-obstruction-due-to-appendiceal-signet-cell-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141362.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">222</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">48</span> Direct Strength Method Approach for Indian Cold Formed Steel Sections with and Without Perforation for Compression Member</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Raghu">K.

Cold-formed steel sections have been developed as more economical building solutions to the alternative heavier hot-rolled sections in the commercial and residential markets. Cold‐formed steel (CFS) structural members are commonly manufactured with perforations to accommodate plumbing, electrical, and heating conduits in the walls and ceilings of buildings. Current design methods available to engineers for predicting the strength of CFS members with perforations are prescriptive and limited to specific perforation locations, spacing, and sizes. The Direct Strength Method (DSM), a relatively new design method for CFS members validated for members with and without perforations, predicts the ultimate strength of general CFS members with the elastic buckling properties of the member cross section. The design compression strength and flexural strength of Indian (IS 811-1987) standard sections is calculated as per North American Specification (AISI-S100 2007) and software CUFSM 4.05. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20strength" title="direct strength">direct strength</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20formed" title=" cold formed"> cold formed</a>, <a href="https://publications.waset.org/abstracts/search?q=perforations" title=" perforations"> perforations</a>, <a href="https://publications.waset.org/abstracts/search?q=CUFSM" title=" CUFSM"> CUFSM</a> </p> <a href="https://publications.waset.org/abstracts/17353/direct-strength-method-approach-for-indian-cold-formed-steel-sections-with-and-without-perforation-for-compression-member" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17353.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">379</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">47</span> Needle Track Technique In Strabismus Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seema%20Dutt%20Bandhu">Seema Dutt Bandhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yashi%20Bansal"> Yashi Bansal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tania%20Moudgil"> Tania Moudgil</a>, <a href="https://publications.waset.org/abstracts/search?q=Barinder%20Kaur"> Barinder Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Scleral perforation during the passage of suture needle is a known complication of strabismus surgery. The present study was conducted to evolve a safe and easy technique of passing the suture needle through the sclera. A scleral tunnel was created with a 26-guage needle through which the suture needle was passed. The rest of the steps of strabismus surgery were carried out as usual. Material and Methods: After taking clearance from the Institutional Ethics Committee, an interventional study was carried out on twenty patients. The scleral tunnel technique was performed on the patients of strabismus after taking written informed consent. Before passing the suture needle through the sclera during strabismus surgery, a tunnel through approximately half the thickness of the sclera was created with the help of a bent 26-gauge needle. The suture needle was then passed through this tunnel. Rest of the steps of the surgery were carried out in the conventional manner. In a control group of same number of patients, the surgery was performed in the conventional method. Both the groups were followed up for any complications. Ease of passing suture and surgeons’ satisfaction with the technique was noted on a 10-point Likert scale. Results: None of the patients in either group suffered from any complications. Four surgeons participated in the study. The average Likert scale score of the surgeons for satisfaction with the technique was 4.5 on a scale of 5. The score for ease of passage of suture needle was 5 on a score of 5. Discussion: Scleral perforation during passing the sutures through the sclera is a known complication of strabismus surgery. Incidence reported is 7.8% It occurs due to inappropriate engagement of the scleral tissue or passage of the suture needle along a wrong axis during the process of passing the suture needle. The needle track technique eases the passage of passing the suture needle through the sclera as the engagement of the scleral tissue can be done with greater control with a 26-guage needle. The surgeons have reported that they are highly satisfied with the technique and they have reported that the technique eased the passage of the suture needle through the sclera. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=suture" title="suture">suture</a>, <a href="https://publications.waset.org/abstracts/search?q=scleral%20tunnel" title=" scleral tunnel"> scleral tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=strabismus" title=" strabismus"> strabismus</a>, <a href="https://publications.waset.org/abstracts/search?q=scleral%20perforation" title=" scleral perforation"> scleral perforation</a> </p> <a href="https://publications.waset.org/abstracts/164236/needle-track-technique-in-strabismus-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164236.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">46</span> Exceptional Cost and Time Optimization with Successful Leak Repair and Restoration of Oil Production: West Kuwait Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasser%20Al-Azmi">Nasser Al-Azmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Al-Sabea%20Salem"> Al-Sabea Salem</a>, <a href="https://publications.waset.org/abstracts/search?q=Abu-Eida%20Abdullah"> Abu-Eida Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Milan%20Patra"> Milan Patra</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elyas"> Mohamed Elyas</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Freile"> Daniel Freile</a>, <a href="https://publications.waset.org/abstracts/search?q=Larisa%20Tagarieva"> Larisa Tagarieva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Well intervention was done along with Production Logging Tools (PLT) to detect sources of water, and to check well integrity for two West Kuwait oil wells started to produce 100 % water. For the first well, to detect the source of water, PLT was performed to check the perforations, no production observed from the bottom two perforation intervals, and an intake of water was observed from the top most perforation. Then a decision was taken to extend the PLT survey from tag depth to the Y-tool. For the second well, the aim was to detect the source of water and if there was a leak in the 7’’liner in front of the upper zones. Data could not be recorded in flowing conditions due to the casing deformation at almost 8300 ft. For the first well from the interpretation of PLT and well integrity data, there was a hole in the 9 5/8'' casing from 8468 ft to 8494 ft producing almost the majority of water, which is 2478 bbl/d. The upper perforation from 10812 ft to 10854 ft was taking 534 stb/d. For the second well, there was a hole in the 7’’liner from 8303 ft MD to 8324 ft MD producing 8334.0 stb/d of water with an intake zone from10322.9-10380.8 ft MD taking the whole fluid. To restore the oil production, W/O rig was mobilized to prevent dump flooding, and during the W/O, the leaking interval was confirmed for both wells. The leakage was cement squeezed and tested at 900-psi positive pressure and 500-psi drawdown pressure. The cement squeeze job was successful. After W/O, the wells kept producing for cleaning, and eventually, the WC reduced to 0%. Regular PLT and well integrity logs are required to study well performance, and well integrity issues, proper cement behind casing is essential to well longevity and well integrity, and the presence of the Y-tool is essential as monitoring of well parameters and ESP to facilitate well intervention tasks. Cost and time optimization in oil and gas and especially during rig operations is crucial. PLT data quality and the accuracy of the interpretations contributed a lot to identify the leakage interval accurately and, in turn, saved a lot of time and reduced the repair cost with almost 35 to 45 %. The added value here was more related to the cost reduction and effective and quick proper decision making based on the economic environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leak" title="leak">leak</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20shut-off" title=" water shut-off"> water shut-off</a>, <a href="https://publications.waset.org/abstracts/search?q=cement" title=" cement"> cement</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20leak" title=" water leak"> water leak</a> </p> <a href="https://publications.waset.org/abstracts/120332/exceptional-cost-and-time-optimization-with-successful-leak-repair-and-restoration-of-oil-production-west-kuwait-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120332.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">115</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">45</span> Modification Of Rubber Swab Tool With Brush To Reduce Rubber Swab Fraction Fishing Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20R.%20Hidayat">T.

During the swab activity, problems occur frequent problems occur with the rubber swab. The rubber swab often breaks and becomes a fish inside the well. This rubber swab fishing activity caused the rig operation takes longer, the swab result data becomes too late and create potential losses of well operation for the company. The average time needed for fishing the fractions of rubber swab plus swab work is 42 hours. Innovation made for such problems is to modify the rubber swab tool. The rubber swab tool is modified by provided a series of brushes at the end part of the tool with a thread of connection in order to improve work safety, so when the rubber swab breaks, the broken swab will be lifted by the brush underneath; therefore, it reduces the loss time for rubber swab fishing. This tool has been applied, it and is proven that with this rubber swab tool modification, the rig operation becomes more efficient because it does not carry out the rubber swab fishing activity. The fish fractions of the rubber swab are lifted up to the surface. Therefore, it saves the fuel cost, and well production potentials are obtained. The average time to do swab work after the application of this modified tool is 8 hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rubber%20swab" title="rubber swab">rubber swab</a>, <a href="https://publications.waset.org/abstracts/search?q=modifikasi%20swab" title=" modifikasi swab"> modifikasi swab</a>, <a href="https://publications.waset.org/abstracts/search?q=brush" title=" brush"> brush</a>, <a href="https://publications.waset.org/abstracts/search?q=fishing%20rubber%20swab" title=" fishing rubber swab"> fishing rubber swab</a>, <a href="https://publications.waset.org/abstracts/search?q=saving%20cost" title=" saving cost"> saving cost</a> </p> <a href="https://publications.waset.org/abstracts/142856/modification-of-rubber-swab-tool-with-brush-to-reduce-rubber-swab-fraction-fishing-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142856.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">167</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">44</span> Pesticidal Potential of Selected Aqueous Plant Extracts for the Control of Webber Caterpillar (Hymenis Recurvalis Fab.)

It is a major limiting factor in amaranth production. Field experiments were conducted during 2022 and 2023 with the aim of assessing insecticidal potential of five selected plant leaf extracts, namely Moringa oleifera, Azadiractha indica A. Juss , Balanites aegyptiaca Del., Momordica balsamina and Hyptis suaveolens using Lambda.cyhalothrin 2.5 EC, a synthetic insecticide as a check. The experiment was conducted in a randomized complete block design (RCBD) replicated three times. Results showed that A.indica and H.suaveolous were more effective in reducing H .recurvalis population, leaf perforation, leaf damaged and improved amaranth plant growth and yield. This was closely followed by B. aegyptiaca and M. balsamina while M. oleifera had the lowest effect on the use of pest population and damage. Lambda.cyhalothrin, a synthetic insecticide, was found to be superior to the five plant extracts. The result showed that A. indica and H. suaveolens improved the growth and yield of amaranth during the study period. The study, therefore, recommended the two plant extracts for the control of leaf webber caterpillar (H. recurvalis) to limited resource farmers and as a good alternative to Lambda.cyhalothrin 2.5EC in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amaranth" title="Amaranth">Amaranth</a>, <a
