There are two main types of lymphoma: Hodgkin's lymphoma and non-Hodgkin's lymphoma. The epidemiological, clinical and biological features of lymphoma are poorly studied in Algeria. The main objective of our study is to investigate the epidemiological, clinical, paraclinical, etiological, evolutionary and biological characteristics of non-Hodgkin's lymphoma (NHL) in the hematology department of the University Hospital Center (HUC) of Batna. This is a study of 10 patients diagnosed at Batna University Hospital. 70% were male and 30% female (sex ratio M/F= 2.33). Median age was 51.7 years. Pain, especially abdominal pain, was the main reason for consultation. Stage IV predominated (40%), followed by stage III (20%). Abdominal adenopathies (34%) were the most abundant. Secondary hepatic localization was predominant. Large B-cell NHL predominated, accounting for 60% of cases, followed by small B-cell NHL (30%). Serology for hepatitis B and C, and human immunodeficiency virus (HIV) was negative. Biologically, a predominance of hyperleukocytosis, polynuclear neutrophilic leukocytosis, lymphopenia and hypoalbuminemia were present in the majority of cases. In summary, our results remain to be compared with other works for other periods and other regions in order to generalize lymphoma percentages for the entire Algerian population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non%20Hodgkin%27s%20lymphoma" title="non Hodgkin's lymphoma">non Hodgkin's lymphoma</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=clinic" title=" clinic"> clinic</a>, <a href="https://publications.waset.org/abstracts/search?q=biology" title=" biology"> biology</a> </p> <a href="https://publications.waset.org/abstracts/188890/study-of-non-hodgkins-lymphoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188890.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">28</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">8</span> High Performance Field Programmable Gate Array-Based Stochastic Low-Density Parity-Check Decoder Design for IEEE 802.3an Standard </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghania%20Zerari">Ghania Zerari</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrezak%20Guessoum"> Abderrezak Guessoum</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Beguenane"> Rachid Beguenane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces high-performance architecture for fully parallel stochastic Low-Density Parity-Check (LDPC) field programmable gate array (FPGA) based LDPC decoder. The new approach is designed to decrease the decoding latency and to reduce the FPGA logic utilisation. To accomplish the target logic utilisation reduction, the routing of the proposed sub-variable node (VN) internal memory is designed to utilize one slice distributed RAM. Furthermore, a VN initialization, using the channel input probability, is achieved to enhance the decoder convergence, without extra resources and without integrating the output saturated-counters.

The aim was to analyze a number of maternal and newborn traits, assess the main causes and risk factors of abnormalities and describe the clinical aspects and different types of birth defects at the maternity of Batna. Our rate of congenital malformations is 19% of hospitalized newborns; mono malformations are the most common, mainly 28% neurological malformations predominated by Spina Bifida and hydrocephalus. Poly malformations accounted for only 15% of our study. 39,61% of newborns are premature. We found a male predominance. The sex ratio is 1.33 male to one girl, most by mothers over 35. The analysis of the pathological history has shown that the diseases encountered in mothers are pregnant HTA and diabetes, these are the most common diseases with a percentage of (19%, and 21%). The percentage of people who use medicine is 28%. In terms of diagnosis, prenatal ultrasounds are performed in 12% of cases, and the death rate is often fairly high at 45%. Congenital malformations remain a problem in terms of treatment and prognosis; this will make it possible to investigate other factors, to better understand the causes of congenital malformations and to develop effective prevention and treatment strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malformation" title="malformation">malformation</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital" title=" congenital"> congenital</a>, <a href="https://publications.waset.org/abstracts/search?q=newborn" title=" newborn"> newborn</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilaya%20of%20%20Batna" title=" Wilaya of Batna"> Wilaya of Batna</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria." title=" Algeria."> Algeria.</a> </p> <a href="https://publications.waset.org/abstracts/193197/study-of-congenital-malformations-in-newborns-in-the-pediatrics-and-neonatology-department-in-the-wilaya-of-batna-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193197.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">17</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">6</span> The Influence of Incorporating Coffee Grounds on Enhancing the Engineering Properties of Expansive Soils: Experimental Approach and Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bencheikh%20Messaouda">Bencheikh Messaouda</a>, <a href="https://publications.waset.org/abstracts/search?q=Aidoud%20Assia"> Aidoud Assia</a>, <a href="https://publications.waset.org/abstracts/search?q=Salima%20Boukour"> Salima Boukour</a>, <a href="https://publications.waset.org/abstracts/search?q=Benamara%20Fatima%20Zohra"> Benamara Fatima Zohra</a>, <a href="https://publications.waset.org/abstracts/search?q=Boukhatem%20Ghania"> Boukhatem Ghania</a>, <a href="https://publications.waset.org/abstracts/search?q=Zegueur%20Chaouki%20Salah%20Eddine"> Zegueur Chaouki Salah Eddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The utilization of waste materials in civil engineering has gained widespread attention in recent years due to their adverse effects on the environment. One such waste material is coffee grounds, a black residue generated daily across the country after coffee brewing. Instead of disposing of it, there is a growing interest in repurposing it for various agricultural and industrial applications. Utilizing coffee grounds in geotechnical engineering, such as in road embankments, presents an opportunity for its valorization. The study aims to contribute to the valorization of coffee grounds by enhancing the physical and mechanical properties of clayey soils through their incorporation at varying weight percentages (3%, 6%, 9%, 12%) as partial replacements in these soils. This not only addresses the issue of coffee ground waste but also makes a tangible contribution to sustainable development. The findings demonstrate that incorporating coffee grounds generally has positive effects on the physical and mechanical properties of clayey soil. However, the extent of these effects depends on factors such as the quantity of coffee grounds added, the particle size of the grounds, and the characteristics of the soil. Additionally, coffee grounds can improve the compression and tensile strength of clayey soil, resulting in increased stability and reduced susceptibility to deformation under external forces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clay%20soil" title="clay soil">clay soil</a>, <a href="https://publications.waset.org/abstracts/search?q=coffee%20grounds" title=" coffee grounds"> coffee grounds</a>, <a href="https://publications.waset.org/abstracts/search?q=optimizing" title=" optimizing"> optimizing</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement" title=" improvement"> improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=valorization" title=" valorization"> valorization</a>, <a href="https://publications.waset.org/abstracts/search?q=waste" title=" waste"> waste</a> </p> <a href="https://publications.waset.org/abstracts/185913/the-influence-of-incorporating-coffee-grounds-on-enhancing-the-engineering-properties-of-expansive-soils-experimental-approach-and-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185913.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">45</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">5</span> Interpretation and Prediction of Geotechnical Soil Parameters Using Ensemble Machine Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Goudjil%20kamel">Goudjil kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Boukhatem%20Ghania"> Boukhatem Ghania</a>, <a href="https://publications.waset.org/abstracts/search?q=Jlailia%20Djihene"> Jlailia Djihene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper delves into the development of a sophisticated desktop application designed to calculate soil bearing capacity and predict limit pressure.

These machines offer significant advantages in terms of efficiency, compactness, and reliability compared to their single-phase counterparts. However, early detection and diagnosis of electrical faults remain critical challenges to ensure the durability and safety of these complex systems. This paper presents an advanced analytical model for multiphase machines, with a particular focus on dual stator asynchronous machines. The primary objective is to develop a robust diagnostic tool capable of effectively detecting and locating electrical faults in these machines, including short circuits, winding faults, and voltage imbalances. The proposed methodology relies on an analytical approach combining electrical machine theory, modeling of magnetic and electrical circuits, and advanced signal analysis techniques. By employing detailed analytical equations, the developed model accurately simulates the behavior of multiphase machines in the presence of electrical faults. The effectiveness of the proposed model is demonstrated through a series of case studies and numerical simulations. In particular, special attention is given to analyzing the dynamic behavior of machines under different types of faults, as well as optimizing diagnostic and recovery strategies. The obtained results pave the way for new advancements in the field of multiphase machine diagnostics, with potential applications in various sectors such as automotive, aerospace, and renewable energies. By providing precise and reliable tools for early fault detection, this research contributes to improving the reliability and durability of complex electrical systems while reducing maintenance and operation costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=faults" title="faults">faults</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20machine" title=" multiphase machine"> multiphase machine</a> </p> <a href="https://publications.waset.org/abstracts/185456/analytical-model-of-multiphase-machines-under-electrical-faults-application-on-dual-stator-asynchronous-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185456.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">63</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">3</span> Forensic Entomology in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Taleb">Meriem Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghania%20Tail"> Ghania Tail</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Zohra%20Kara"> Fatma Zohra Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Djedouani"> Brahim Djedouani</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Moussa"> T.

The main purpose of forensic entomology is to establish the postmortem interval or PMI Postmortem interval is a matter of crucial importance in the investigations of homicide and other untimely deaths when the body found is after three days. Forensic entomology has grown immensely as a discipline in the past thirty years. In Algeria, forensic entomology was introduced in 2010 by the National Institute for Criminalistics and Criminology of the National Gendarmerie (NICC). However, all the work that has been done so far in this growing field in Algeria has been unknown at both the national and international levels. In this context, the aim of this paper is to describe the state of forensic entomology in Algeria. The Laboratory of Entomology of the NICC is the only one of its kind in Algeria. It started its activities in 2010, consisting of two specialists. The main missions of the laboratory are estimation of the PMI by the analysis of entomological evidence, and determination if the body was moved. Currently, the laboratory is performing different tasks such as the expert work required by investigators to estimate the PMI using the insects. The estimation is performed by the accumulated degree days method (ADD) in most of the cases except for those where the cadaver is in dry decay. To assure the quality of the entomological evidence, crime scene personnel are trained by the laboratory of Entomology of the NICC. Recently, undergraduate and graduate students have been studying carrion ecology and insect activity in different geographic locations of Algeria using rabbits and wild boar cadavers as animal models. The Laboratory of Entomology of the NICC has also been involved in some of these research projects. Entomotoxicology experiments are also conducted with the collaboration of the Toxicology Department of the NICC. By dint of hard work that has been performed by the Laboratory of Entomology of the NICC, official bodies have been adopting more and more the use of entomological evidence in criminal investigations in Algeria, which is commendable. It is important, therefore, that steps are taken to fill in the gaps in the knowledge necessary for entomological evidence to have a useful future in criminal investigations in Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=corpse" title=" corpse"> corpse</a>, <a href="https://publications.waset.org/abstracts/search?q=insects" title=" insects"> insects</a>, <a href="https://publications.waset.org/abstracts/search?q=postmortem%20interval" title=" postmortem interval"> postmortem interval</a>, <a href="https://publications.waset.org/abstracts/search?q=expertise" title=" expertise"> expertise</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34230/forensic-entomology-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34230.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">2</span> Application of Forensic Entomology to Estimate the Post Mortem Interval</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Taleb">Meriem Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghania%20Tail"> Ghania Tail</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Zohra%20Kara"> Fatma Zohra Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Djedouani"> Brahim Djedouani</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Moussa"> T. Moussa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forensic entomology has grown immensely as a discipline in the past thirty years. The main purpose of forensic entomology is to establish the post mortem interval or PMI. Three days after the death, insect evidence is often the most accurate and sometimes the only method of determining elapsed time since death. This work presents the estimation of the PMI in an experiment to test the reliability of the accumulated degree days (ADD) method and the application of this method in a real case. The study was conducted at the Laboratory of Entomology at the National Institute for Criminalistics and Criminology of the National Gendarmerie, Algeria. The domestic rabbit Oryctolagus cuniculus L. was selected as the animal model. On 08th July 2012, the animal was killed. Larvae were collected and raised to adulthood. Estimation of oviposition time was calculated by summing up average daily temperatures minus minimum development temperature (also specific to each species). When the sum is reached, it corresponds to the oviposition day. Weather data were obtained from the nearest meteorological station. After rearing was accomplished, three species emerged: Lucilia sericata, Chrysomya albiceps, and Sarcophaga africa. For Chrysomya albiceps species, a cumulation of 186掳C is necessary. The emergence of adults occured on 22nd July 2012. A value of 193.4掳C is reached on 9th August 2012. Lucilia sericata species require a cumulation of 207掳C. The emergence of adults occurred on 23rd, July 2012. A value of 211.35掳C is reached on 9th August 2012. We should also consider that oviposition may occur more than 12 hours after death. Thus, the obtained PMI is in agreement with the actual time of death. We illustrate the use of this method during the investigation of a case of a decaying human body found on 03rd March 2015 in Bechar, South West of Algerian desert. Maggots were collected and sent to the Laboratory of Entomology. Lucilia sericata adults were identified on 24th March 2015 after emergence. A sum of 211.6掳C was reached on 1st March 2015 which corresponds to the estimated day of oviposition. Therefore, the estimated date of death is 1st March 2015 卤 24 hours. The estimated PMI by accumulated degree days (ADD) method seems to be very precise. Entomological evidence should always be used in homicide investigations when the time of death cannot be determined by other methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=accumulated%20degree%20days" title=" accumulated degree days"> accumulated degree days</a>, <a href="https://publications.waset.org/abstracts/search?q=postmortem%20interval" title=" postmortem interval"> postmortem interval</a>, <a href="https://publications.waset.org/abstracts/search?q=diptera" title=" diptera"> diptera</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34231/application-of-forensic-entomology-to-estimate-the-post-mortem-interval" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34231.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">294</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">1</span> Evaluation of the Boiling Liquid Expanding Vapor Explosion Thermal Effects in Hassi R'Mel Gas Processing Plant Using Fire Dynamics Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brady%20Manescau">Brady Manescau</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilyas%20Sellami"> Ilyas Sellami</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Chetehouna"> Khaled Chetehouna</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20De%20Izarra"> Charles De Izarra</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Nait-Said"> Rachid Nait-Said</a>, <a href="https://publications.waset.org/abstracts/search?q=Fati%20Zidani"> Fati Zidani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During a fire in an oil and gas refinery, several thermal accidents can occur and cause serious damage to people and environment. Among these accidents, the BLEVE (Boiling Liquid Expanding Vapor Explosion) is most observed and remains a major concern for risk decision-makers. It corresponds to a violent vaporization of explosive nature following the rupture of a vessel containing a liquid at a temperature significantly higher than its normal boiling point at atmospheric pressure. Their effects on the environment generally appear in three ways: blast overpressure, radiation from the fireball if the liquid involved is flammable and fragment hazards. In order to estimate the potential damage that would be caused by such an explosion, risk decision-makers often use quantitative risk analysis (QRA). This analysis is a rigorous and advanced approach that requires a reliable data in order to obtain a good estimate and control of risks. However, in most cases, the data used in QRA are obtained from the empirical correlations. These empirical correlations generally overestimate BLEVE effects because they are based on simplifications and do not take into account real parameters like the geometry effect. Considering that these risk analyses are based on an assessment of BLEVE effects on human life and plant equipment, more precise and reliable data should be provided. From this point of view, the CFD modeling of BLEVE effects appears as a solution to the empirical law limitations. In this context, the main objective is to develop a numerical tool in order to predict BLEVE thermal effects using the CFD code FDS version 6. Simulations are carried out with a mesh size of 1 m. The fireball source is modeled as a vertical release of hot fuel in a short time. The modeling of fireball dynamics is based on a single step combustion using an EDC model coupled with the default LES turbulence model. Fireball characteristics (diameter, height, heat flux and lifetime) issued from the large scale BAM experiment are used to demonstrate the ability of FDS to simulate the various steps of the BLEVE phenomenon from ignition up to total burnout. The influence of release parameters such as the injection rate and the radiative fraction on the fireball heat flux is also presented. Predictions are very encouraging and show good agreement in comparison with BAM experiment data. In addition, a numerical study is carried out on an operational propane accumulator in an Algerian gas processing plant of SONATRACH company located in the Hassi R鈥橫el Gas Field (the largest gas field in Algeria). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BLEVE%20effects" title="BLEVE effects">BLEVE effects</a>, <a
