Published: September 2024

The clinical manifestations of neurofibromatosis type-1 have in common the presence of neurofibromas, schwannomas and cafe`-au-lait macules, which can potentially appear within any organ system of the body, involving primarily the skeleton, skin and soft tissues. The spinal thoracic tuberculoma in neurofibromatosis is exceptional.
We report here, the case of a 31-year-old male with neurofibromatosis type-1 who presented a year agoa spinal thoracic pain. The evolution was marked by the appearance of a dorsal para-vertebral mass, progressively increasing in volume for 03 months.
Neurological Examination revealed normal muscle bulk and tone, and power was grade 5/5. Deep tendon reflexes were brisk and the Babinski sign was present. The sensory deficit was present below the D9 level. The remainder of the examination found a voluminous dorsal para vertebral mass ovoid, renitent, and adhering to the superficial and the deep planes. There were also "café-au-lait" spots disseminated on his body. The imagery showed a formation with respect to D11-D12, isointense on T1 and T2, heterogeneously enhanced after contrast with central necrosis, with a foraminal starting point measuring 85x78x66 mm, with external canal extension. Laminectomy D11-D12 was performed with incomplete excision of the lesion. The histological examination showed casein-follicular vertebral tuberculosis, with secondary abdominal changes. Then the patient was put on anti-bacillary drugs. The evolution was marked two weeks later by the reappearance of the back pain and the back mass. On the 42nd day of treatment, the patient had a febrile consciousness disorder with a GCS of 8, right mydriasis and meningeal stiffness. Paraclinic investigations revealed tuberculosis meningoencephalitis, responsible for an active ventricular hydrocephalus associated with a left temporoparietal extrudal hematoma. An external ventricular shunt was performed as well as a left temporo-parietal extrudal hematoma evacuation. The patient died 7 days later in a poly visceral failure chart.

Published: September 2024

Gravitational bullet injuries, prevalent in the Middle East, particularly in Iraq, are a critical public health concern, often resulting from celebratory gunfire. In our Neurosurgery Teaching Hospital in Baghdad, we've observed that these injuries differ significantly from high-velocity gunshot wounds, characterized by lower velocity and energy due to air resistance and gravity. Unlike high-velocity bullets, gravitational bullets cause less bone fragmentation and radial brain damage. These bullets often end up on the tentorium or within the skull base, rarely transgressing the cerebellar tentorium on a vertical trajectory.  We've also noticed that the pediatric population, particularly younger children, are more susceptible to these injuries due to their thinner cranial vertex, leading to more penetrating injuries and aggressive brain bleeding. Our observations underline the need for focused studies, awareness, regulation, and tailored management strategies to combat this overlooked issue.

Introduction: The posterior auricular artery (PAA) is the preterminal branch of the external carotid artery (ECA), arising superiorly to the occipital artery (OA). The PAA has quite a few anatomical variations and established neurosurgical applications. We conducted this study as an overview to illustrate all neurosurgical aspects regarding this artery, its reconstructive uses, and anatomical variation.
Method:  We performed a literature review in Google Scholar and PubMed medical databases for studies discussing the PAA, its anatomical variations, and neurosurgical applications.
Results: We identified 30 articles that discuss the anatomical variations and neurosurgical applications of the PAA. While reviewing the available articles and original works regarding PAA.
Conclusion: The PAA has considerable anatomical variations regarding its origin, course, branches, and length. The related neurosurgical applications of PAA include bypass, embolization, aneurysm, AVM, and reconstruction flaps.

Published: September 2024

Introduction. The supratrochlear artery (STA) is a small vessel with a relatively tiny and quite constant course. The literature describing the STA fails to provide a collective description of the anatomy and neurosurgical applications of the STA. Therefore, we are here to present an overview of anatomy, anatomical variability, and the clinical application of STA.
Method.  We conducted a literature review in Google Scholar and PubMed medical databases to review the existing studies on STA regarding its anatomy and neurosurgical applications.
Results. We identified 18 articles that discuss the anatomical variations and neurosurgical applications of the STA. Certain parameters are used to describe the surgical anatomy of STA, including origin, course, diameter, branches, depth, and distance in relation to the midline and vertical glabellar line. We also discussed certain applications of STA and its importance in neurosurgical reconstruction flaps and the diagnosis of carotid artery disease.
Conclusion. Comparable to the supraorbital artery (SOA), the STA is less variable in its anatomical course, and exhibits a more superficial course. The STA has certain important neurosurgical applications through its involvement in reconstruction flaps for the skull base and plays an important role in the diagnosis of carotid artery disease.
Decompressive craniectomy for dural venous sinus thrombosis
Authors: Campero Álvaro , González Méndez Roberto , Baldoncini Matias , Ortega Sierra Michael Gregorio
Published: September 2024

A rare event, dural sinus thrombosis occurs more frequently in young adults and children. Generally, medical treatment is the preferred option for this condition; however, if no improvement is observed with medical treatment, decompressive craniectomy is suggested as the preferred surgical intervention. A non-systematic literature search was conducted in PubMed and SCOPUS databases until June 2023, using keywords such as "Decompressive craniectomy," "Dural venous sinus thrombosis," and "Traumatic Brain Injury," along with their synonyms in both English and Spanish. The search revealed that genetic or acquired thrombophilia and the use of oral contraceptives were the most common risk factors, explaining the female predominance of this condition. Patients with dural sinus thrombosis commonly experience headaches, the intensity of which is not yet considered pathognomonic for the condition, ranging from mild to severe. Other nonspecific symptoms include nausea, vomiting, and papilledema. Thrombolytic agents are utilized to rapidly dissolve the clot, supported by interventional neuroradiology techniques to administer the agent directly at the thrombosis site. Studies have reported the effectiveness of emergent decompressive craniectomy in patients with recent onset of dural sinus thrombosis, leading to good results, especially in cases where cerebral hernia is present.

Authors: Rai Ashish , Shekhawat Jitendra S. , Jain Gaurav , P.V. Sripadma
Published: September 2024

Aim: With only limited treatment options in acute spinal cord injury (SCI) currently available, we aimed to investigate the effect of progesterone on neurological recovery after acute SCI.
Material and Methods: Randomised double-blind placebo-controlled single-centre trial on 128 patients of acute SCI (within 24 hours of injury) was conducted at our institute with the approval of the ethics committee. Eligible patients were allocated to the progesterone or placebo arm. Of 133 eligible patients, one from the placebo arm expired in the acute phase while 4 were lost to follow-up, leaving 128 patients in the study.68 patients remained in the progesterone arm and 60 in placebo. Patients in the progesterone arm received intramuscular progesterone while those in the placebo received intramuscular isotonic saline twice daily for five consecutive days. Neurological assessment was done at baseline, day six, first and sixth months using the American Spinal Injury Association (ASIA) score and motor and sensory actual neural recovery (ANR) scores.
Results: Baseline characteristics were comparable between the groups. At the end of six months, significant improvement occurred in motor and sensory ASIA scores in the progesterone arm (p=<0.01). Compared with the placebo, motor scores were significantly higher in the progesterone arm at 6 months while sensory scores were not (p= <0.01 and p= 0.59 respectively). Additionally, at 6 months, motor ANR was significantly higher in the progesterone arm vs placebo (p=<0.01 vs 0.65). Early progesterone administration (within six hours of injury) was associated with significantly higher motor and sensory ASIA scores at 6 months (p= <0.01vs0.04 respectively).
Conclusion: Administration of intramuscular progesterone within 24 hours in acute SCI was associated with better neurological recovery. Further multicentric studies are required to shed more light on the strength and consistency of this improved outcome.
Developing a data-enabled nudge intervention for childhood antibiotics in primary care: a qualitative study
Authors: Van Hecke Oliver , Borek Aleksandra , Butler Christopher , Tonkin-Crine Sarah
Published: September 2024

Background

Preschool children (aged ≤5 years) have the highest antibiotic prescribing rate in general practice, mostly for self-limiting acute respiratory tract infections (RTIs). Research from >250 000 UK children suggests that a child’s antibiotic history for RTI may be a good predictor for re-consulting a health professional for the same illness episode and increased clinical workload.

Aim

To develop a data-enabled nudge intervention to optimise antibiotic prescribing for acute RTI based on a child’s antibiotic history in general practice.

Design & setting

Two-phase qualitative study with parents or carers of preschool children and primary care clinicians in England.

Method

In phase 1, through an initial focus group with eight parents or carers and ‘think-aloud’ interviews with 11 clinicians, we co-designed the intervention (computer-screen prompt and personalised consultation leaflet). In phase 2, 13 clinicians used the intervention, integrated into the GP computer software, and shared their feedback through ‘think-aloud’ interviews. Interviews were audio-recorded, transcribed, and analysed thematically.

Results

We co-created a data-driven intervention that automatically integrates a child’s antibiotic history for acute RTI and personalised leaflet into the electronic medical records. We found that parents and clinicians found this intervention, in principle, acceptable and feasible to use in primary care consultations. GP participants reflected on the prompt’s novelty and its usefulness of taking stock of the number of antibiotic prescriptions a child has had in the past year.

Conclusion

Delivering such interventions, integrated into practice workflow, could be efficiently scaled up to promote effective antimicrobial stewardship and reduce unnecessary antibiotic use in primary care. Further research will test this intervention in a future trial.

Published: September 2024

Background: Knee osteoarthritis (KOA) is the most common destructive disease of the knee joint. The purpose of the present study was to design to psychometrically assess a checklist for knee care behaviors in housewives living in Yasuj, Iran. Methods: This study was conducted from 2019 to 2021. Medline, Google Scholar, and SID databases were searched using keywords such as KOA, menopause, instrument, self-care behavior, and women. The first draft of the checklist, consisting of 41 items, was prepared, and 10 experts assessed its wording, content validity index (CVI), and content validity ratio (CVR). Cronbach’s alpha and test re-test were utilized to assess the reliability of the tool. Results: Content validities confirmed the 38-item tool with 5 dimensions of standing, sitting, walking, sleeping, and exercise practicing, which were rated on a yes (score 1) or no (score 0) response. The total values for CVR and CVI for the tool were 0.97 and 0.88, respectively. Cornbrash’s alpha and test re-test coefficient of 5 dimensions were above 0.7, which was in an acceptable range. Conclusion: The study findings suggest that the 38-item tailor-made knee self-care checklist is a valid and reliable tool. Indeed, this instrument could be used by healthcare providers in health centers for evaluating knee self-care behaviors in KOA-suffered women. Furthermore, this checklist is worthy of use to further help determine the risky behaviors of women while doing daily activities and to design appropriate practical and educational interventions for improving their knee-related behaviors.

Authors: Yangyuen Suneerat , Somdee Thidarat , Yin Meihua , Chaichan Atchara
Published: September 2024

Background: Alcohol craving is one factor contributing to subsequent increased drinking and relapse in adults and adolescents with alcohol use disorders (AUDs). However, little is known about alcohol craving and its associated factors in non-treatment-seeking Thai adolescent drinkers. Hence, this study aimed to explore factors related to alcohol craving among Thai adolescent hazardous drinkers. Methods: A cross-sectional design was performed on 617 adolescent drinkers from three universities in northeastern Thailand who were selected by the multi-stage random sampling method. A self-reported questionnaire was used for data collection. Multiple logistic regression was applied to investigate factors influencing alcohol craving. Results: Most adolescents were male (51.1%), and approximately 55.4% of them reported craving for alcohol. The greater cravings were found in the presence of alcohol-related cues, such as being at a party or in a pub or bar, showing alcohol-related stimuli (sights, sounds, and smells), drinking with peers or others, and drinking on weekends. Psychological factors such as positive alcohol expectancies, perceived stress, and negative affect were related to a higher level of alcohol craving and were inversely related to negative alcohol expectancies and positive affect. Conclusion: Understanding the effects of alcohol-related cues and psychological factors on alcohol cravings may be useful for health professionals to identify which adolescent drinkers are at risk of renewed drinking and design potential target interventions to reduce cravings.

Published: September 2024

Background: This study was conducted to determine how the theory of planned behavior (TPB) can be applied as a theoretical framework for managing iron deficiency anemia among student girls. Methods: This quasi-experimental study was conducted in descriptive and interventional phases on student girls residing in Fariman, Iran. In the descriptive phase, 200 students were selected by multi-stage random sampling. In the intervention phase, 80 students were randomly divided into experimental and control groups. Data were collected using two questionnaires. One questionnaire included questions about demographic variables, and the other was a TPB construct questionnaire. The educational program was held based on the TPB model for the intervention group in four sessions. The intervention was evaluated immediately and three months after the training session. The data were analyzed by SPSS 20 using repeated measures, ANOVA, t-tests, and linear correlation. Results: In this study, the research sample consisted of 200 student girls with a mean age of 13.11±0.5. Before the intervention, there was no statistically significant difference in the average preventive nutrition behavior score between the two groups (P>0.05). However, after the education in the intervention group, the subjective norm score and perceived behavioral control increased from 8.19±0.98 to 8.88±1.2 and from 18.1±3.6 to 19.8±3.3, respectively. In addition, intention and preventive behavior increased from 14.6±2 to 16.05±1.9 and from 24.8±4.5 to 26.9±4.1, respectively. These differences were found to be statistically significant (P>0.05). Conclusion: The results of this study demonstrated that educational interventions based on the TPB model can be effective in promoting preventive behaviors for anemia.
Non-pharmacological Management of Hypertension in Arab Countries: A Scoping Review
Authors: Matani Nasir , Hassan Intan Idiana , Rohana AJ , Nazzal Mohammad
Published: September 2024

Background: Non-pharmacological interventions, such as healthy dietary approaches and physical activity, have always been a crucial part of hypertension (HTN) control in clinical practice. These non-pharmacological interventions, however, have never been reviewed in the literature of Arab countries. This review has quantified and evaluated non-pharmacological interventional studies conducted in Arab countries until 2023. Methods: Medline, Web of Science, PubMed, the Cochrane Library, Embase, Science Direct, Scopus, ERIC, ProQuest, Springer, Google Scholar, and CINAHL were explored from database inception until September 2023. Articles of relevance were screened based on their titles and abstracts for selection criteria. Eligible studies were reviewed, and information was retrieved. Jadad scores and the Downs and Black checklist were used to evaluate randomized controlled trials (RCTs) and quasi-experimental studies, respectively. Results: A total of 12 RCTs and 5 quasi-experimental studies met the selection criteria. The studied interventions were eHealth applications, educational programs, wet cupping, physical exercise, adherence therapy, green tea, lifestyle interventions, dietary approaches to stop HTN, motivational interviewing, and cold hibiscus beverages. The most commonly used outcome measure was blood pressure. Nine studies scored high quality. The low and neutral quality scores were mainly due to loss of blindness, poor reporting of participants’ characteristics, loss of follow-up, and failure to account for potential confounders. Conclusion: There is a scarcity of HTN non-pharmacological interventional studies, aside from the low or modest quality of nearly 50% of them. Hence, it is recommended that further high-quality interventional studies focus on the areas of dietary approaches (especially DASH), exercise, theory-based education, and behavioral counseling in Arab countries.

Published: September 2024

Wheat cultivation is important in Turkish agriculture, which ranks 10th among international wheat producers, and is an important wheat exporter, particularly to Europe. Fusarium-related threats, such as Fusarium Head Blight (FHB) and Fusarium Crown and Root Rots (FCR, FRR), and related mycotoxin seed contamination, jeopardize product quality. This study analysed 65 wheat seed samples for presence of Fusarium species, from cultivars of Triticum aestivum (bread wheat) and T. durum (durum wheat) collected from seven regions of Türkiye. PCR with specific primers, and phylogenetic analyses of TEF1-α segments, discriminated Fusarium species. Levels of the mycotoxin deoxynivalenol (DON) in flour samples were also evaluated. Out of 195 Fusarium isolates, the prominent species included F. graminearum (32% of isolates), F. proliferatum (16%), F. avenaceum (11%), F. clavum (11%), and F. verticillioides (7%). Less frequently isolated species were F. oxysporum (6%), F. acuminatum (3%), F. ramigenum (3%), F. culmorum (3%), F. poae (2%), F. sambucinum (2%), F. tricinctum (2%), Fusarium sp. FTSC12 (2%), F. andiyazi (1%), and F. equiseti, F. incarnatum, and F. fasciculatum (each 0.5%). Five of the 65 samples tested positive for DON, with two exceeding the European Commission threshold for mycotoxin contamination; one bread wheat from the Black Sea region, known for its annual rainfall, and a durum wheat sample from southeastern Anatolia, which had the highest detected DON level of 1730 μg kg-1. Among these samples F. graminearum was the predominant species. As F. andiyazi and F. ramigenum are not normally associated with wheat plants, a pathogenicity test was conducted with two isolates of each of these species, revealing no pathogenicity on the durum wheat cultivar ‘San Carlo’. These results provide a basis for managing fungal threats and mycotoxin contamination, safeguarding the quality of wheat grain as an essential agricultural product.

Introducción: La neuralgia del trigémino corresponde a la neuralgia craneofacial más frecuente, cursa con dolor intenso, debilitante, en hemicara y que afecta la calidad de vida de los pacientes, teniendo como causa principal un conflicto neurovascular. Sin embargo, en casos refractarios, se indican distintos tratamientos quirúrgicos, siendo la cirugía de descompresión neurovascular la más efectiva, el presente trabajo, presenta una serie clínica personal de cirugía de descompresión neurovascular. Materiales y Métodos: Estudio retrospectivo, 20 casos operados por el autor principal del trabajo, entre 2018 y 2022. Resultados: El alivio del dolor inmediato, se obtuvo en el 100% de los casos y a los 18 meses de seguimiento, en 90% de los pacientes. Con respecto al estudio preoperatorio, en la resonancia magnética, en 3 casos no se informó conflicto neurovascular. Sin embargo, en dos de estos pacientes, si se encontró conflicto neurovascular en el intraoperatorio. En cuanto a las complicaciones, dos pacientes presentaron fistula de líquido cefalorraquídeo y un caso paresia facial que revirtió a los 6 meses de seguimiento. Discusión y Conclusión: Varias series destacan una especificidad relativamente baja de la resonancia para demostrar conflicto neurovascular, por lo tanto, si la imagen no demuestra conflicto neurovascular, esto no debería descarta la indicación de cirugía y en caso de no hallar compresión vascular, la neurolisis directa también ha mostrado una efectividad alta en la resolución del dolor. La descompresiva neurovascular en neuralgia del trigémino es segura y efectiva.
Harmonics Cancelation in 3-Phase 4-Wire System using Modified Reference Frame
Authors: Abdusalam Mohamed , Abdusalam Mohamed
Published: September 2024

In this paper, A modified synchronous reference frame (SRF) or (d-q theory) with Self-Tuning Filter (STF) for the three-phase four wires system is presented to control of 4-legs shunt active power filter (SAPF) under balanced supply voltages. The main goal of the paper is to apply this control method using unit vector generation with STF instead of PLL circuit. In utility power system, it has been observed that harmonics build a major role in reducing the power quality. These harmonics caused by nonlinear loads. Many consumers appliances demand quality of power continuously for their operation. The performance of the end user equipment is heavily dependent on the quality of power supplied to it. This power is affected by various external and internal factors. They are like voltage and frequency variations, faults, outages etc. The solution to overcome these problems is to filter out these harmonics. For this purpose, there are many filters' topologies and control methods are proposed and studied in the literature to eliminate harmonics currents. In our study, 4-legs shunt active power filter is proposed and controlled by d-q method with modified unit vector generation. The SAPF is proposed to solve problems of line harmonic currents and neutral line currents of three phase 4-wire power distribution system. The use of STF in the modified control method can optimize the performance of this topology regarding to classical one (high pass and low pass filters). The proposed control strategy is simulated in MATLAB Simulink and the results are presented.

Authors: Elzaroug Omer , Boalhasia Rowida
Published: September 2024

Concrete structures are exposed to sulfate and chloride attacks when are used in different environments such as seawater, deicing salts or industrial waste. Sulfate corrosion is considered one of the most important factors that responses for deterioration of construction materials performance. When sulfate attacks concrete, sulfate ions interact with cement materials to form chemical compounds inside the concrete. These compounds result volume increase and create internal stresses causing cracks, spalling and reduction in concrete strength. In this paper, the effect of external sulfate attack on properties of concrete samples enhanced with and without steel fibers (SF) and on bond damage between glass fibers reinforced polymer GFRP bar and concrete were investigated. Samples were completely immersed in 10% magnesium sulfate solution for two different exposure periods (60 & 120 days) to compare with control samples. Compressive and tensile strengths, density and pulse velocity were experimentally investigated. Push-out test was also carried out to study the damage in bond between concrete and GFRP rod. The results of concrete samples immersed in magnesium sulfate solution for 60 days showed an increase in compressive strength, tensile strength and density, while the results decreased for samples immersed for 120 days.
A Loadability Study of 30 kV Misurata Distribution Network
Authors: Elsagahyer Etohami , Abdulmalek Jamal , Abojlala Khaled
Published: September 2024

Due to the expansion of power distribution networks, the power delivered to the loads might get through corridors which limits their capability of transmitting the power. This concept is termed as the loadability. An unplanned increase in power consumption in the Libyan network, especially after 2011, led to major problems at different levels of the power network. For instance, these issues are addressed at the generation level as power shortages and load shedding while at the distribution level presented as under voltages and loadability issues. In this paper, a study of the loadability of 30 kV Misurata electrical distribution network (MDN) is carried out using the NEPLAN software. Even though the MDN is considered one of the largest distribution networks in Libya, a lack of data is found which makes an ambiguous vision about this network and the necessary developments required in the future as well as adds some difficulties to making studies. The work presents the steady state operation of MDN under the existence of the current and estimated loads up to the year 2026. The results show significant loading problems in Misurata distribution network which should be considered to avoid the anticipated future power transfer limitations.

The road construction industry significantly contributes to the socio-economic development of a country. However, road construction industries all over the world, including Libya, are facing serious problems related to construction delays, which result in higher costs for the Department of Transportation and contractors as well as cause great inconvenience to the public. The challenges faced by road construction projects in Northwest Libya have resulted in the late delivery of road construction supplies and increased the number of problematic and abandoned projects. Consequently, these delays will result in cost overruns and quality degradation. This study also develops a structural model of road construction delay and determines those groups that greatly contribute to road construction delay through a questionnaire survey. A total of 256 questionnaires were returned for the main study, thereby yielding a 71% response rate. The structural model of road construction delay was developed by using structural equation modelling. This model is deemed fit as the coefficient of determination (R of road construction delay was 0.48 (R2 ≥ 0.26 = substantial . The model shows that all eleven groups are significant with p-value>0.05, thereby suggesting that all fit indices satisfy the proposed value range assumed for the model development. The model also shows that the contractors group and effects of financial activities, specifically ‘time and cost overrun as well as poor quality’, have the highest effects on road construction delay. The findings of this study contributed to understand clearly the cause effect factors of construction delay in Libya.
Evaluating the Mechanical and Rheological Behavior of Mud-contaminated Well Cements

Oil and gas well cementing is the process of filling the gap between wellbore and casing with cement to support casing and prevent communication between formations behind casing. A good and consistent cement slurry is critical for cement job success and, consequently, very important for well integrity and performance throughout the life of the well.When cement slurry is pumped down the casing in a cementing job, it comes in a direct contact with drilling fluids used to drill the uncased section. These fluids, if mixed with cement slurries, can act as contaminants causing an alteration in the properties of cement. It is, therefore, critical to evaluate the extent of cement properties alteration due to contamination by drilling and completion fluids.In this work, an experimental study was carried out to investigate the effect of contamination by drilling fluids; water based, oil based (50% Diesel, 50% water) and oil based (70% diesel, 30% water) on cement physical, mechanical and rheological properties.Cement slurries were prepared according to the API procedures and were mixed with different concentration of contaminants and cured at ambient temperature for 1, 2, 3 and 21 days. Physical, rheological, and mechanical properties were measured using API recommended practices and apparatus.It is observed and as expected that regardless of mud base fluid, as contaminant percentage increases, density of cement slurry decreases due to dilution of cement by water in contaminant. For oil-based invert emulations (50/50 and 70/30), as contamination percentage increased plastic viscosity increased, but yield stress decreased. It was also found that clean and less contaminated cement samples develop higher compressive strength in shorter times than mud contaminated samples.
Using of "Mathlab Fcn." For Realistic simulation of AC Motor Overload Protection
Authors: Jannat Mohamed
Published: September 2024

Motor overload protection is a protection against overcurrent that may cause motor overheating which leads to motor damage. In overload protection relays, some techniques depend on current crossing the motor, motor thermal constants, operating time, and ambient temperature to estimate continuously the temperature of the motor. Therefore, it is closer to reality and can prevent inadvertent tripping. The paper proposes a new method to simulate this motor overload protection using MATLAB/Simulink. This method estimates continuously the percentage overtemperature of the motor. The "MATLAB Fcn" block is used to pass input values to a function in "MATLAB", to perform some calculations, and return a value in each step. This value determines whether the motor will keep running or not.

Soil reinforcement technique is a method for improving the engineering properties of soil to develop parameters such as shear strength, compressibility and absorption of tensile loads. By incorporating materials that resist tensile stress and shear stresses to improve soil strength. Recently, traditional inert materials were replaced with material waste material. Useful materials can be produced from non-useful waste materials leads to use the plastic products like polystyrene. The main idea this research was to conduct experimental investigation for the understanding and evaluation of the interaction between clay soils and polystyrene. In purpose of examination of the effect the induced materials on behaviors of the clay; tests were carried out on different portions of polystyrene contents to test the unconfined compression. The results showed that increasing the EPS content decreased the maximum dry density while increasing the optimum moisture content. The addition of EPS to the soil would reduction of unconfined compression strength (UCS). Reinforced specimens, on the other hand, tended to reach their peak strength at higher strains. The addition of EPS chips reduces the weight of the soil while increasing its flexibility.
Excessive Water Production Analysis in the Abu-Attifel Oil Field Using Chan's Diagnostic Plots
Authors: Arwini Saleh
Published: September 2024

Excessive water production is one of the major problems in mature Libyan oil fields. Water production has the potential to reduce the productive life of oil and gas wells while also causing serious issues such as tubular corrosion, fines migration, and hydrostatic loading. The aim of this paper is to diagnose and evaluate excessive water production mechanisms in the Abu-Attifel Oil Field using Chan’s diagnostic plots. This technique was applied to seven wells in the Abu-Attifel oil field. After a strong depletion phase, water injection was set up and started in the field in 1974. The Chan’s diagnostic plots method is applied using Microsoft Excel format to calculate and plot the derivative response to understand the excessive water production mechanism. The diagnostic plots showed some random and noisy trends on both the WOR and WOR’ plots; hence, they provide a controversial basis for characterizing water production based on surface observation of production trends. The multilayer channeling with production changes could be one reason for the excessive water production in the studied wells. The results obtained need to be verified by close monitoring using production logging tools (PLT) and well testing techniques to ensure breakthrough time and identify the main reasons for excessive water production

This paper was conducted to characterize the aerodynamic behaviour of the blade wind turbine (Ge1.5xle) by computational fluid dynamics (CFD), the simulation was performed typical to the blade of Ge1.5xle which is 41.25 m length using three different airfoils S818, S825 and S826 for the blade root, primary and tip respectively. The blade was added one meter for fixation to the hub of rotation. The blade designed to be twist by 42 degrees from first airfoil place to the last one at the tip of the blade with attack angle is 4 degree based on the specification of the wind turbine Ge 1.5xle to enable comparison the results of computational fluid dynamics (CFD) with the specification data of wind turbine mentioned above, also with the theoretical calculations. The results of simulation at rated wind speed 11.5 (m/s) are agreed with the specification data of the wind turbine such as the aerodynamic efficiency is 29(%), but obvious variation is observed for blade tip speed. Furthermore, the velocity vectors are in good agreement with flow characteristic and the flow was perfectly attached and there is no flow separation over the three different airfoils used.
