Authors: Hwang Hyun-Kyu , Kim Seong-Jong
Published: July 2023

In this investigation, plasma ion nitriding was conducted to improve the hardness, wear resistance, and hydrogen embrittlement resistance of aluminum alloys. To research the surface characteristics and hydrogen embrittlement resistance of the nitrided layer, indentation experiments, scratch experiments, friction experiments, FE-SEM, XRD, EDS, and 3D laser microscopic analyses were conducted. An AlN layer was observed on the surface after plasma ion nitriding. As a results of the indentation experiment, hardness (H
IT) of the nitrided layer decreased from 1370 to 749 MPa and 538 MPa, respectively with hydrogen embrittlement for 3 h and 6 h. As a result of hydrogen embrittlement, adhesion force between the base material and nitrided layer tended to decrease from 6.54 to 2.50 N. In addition, as a results of the friction experiment, the section where the nitrided layer was maintained was shortened as the hydrogen embrittlement time increased.

Sayyid Muhammad al-Hassani al-Baghdadi and his approach to writing history
Authors: العزاوي علاوي , مرضي كرار
Published: July 2023

Al-Saied Mohammed Al-Hasani Al-Baghdadi interpreted history in a philosophical jurisprudential way according to his pure religious culture. In addition, the works and readings from which we drew Al-Baghdadi view to history studied the history from a religious point of view in particular. He skipped out any work related to the origins of western history of all tendencies and schools. Accordingly, we comprehended that his views came to support our interest and understanding of our Islamic heritage in general and our Shiite heritage in particular. This does not imply that Al-Baghdadi adopts a methodological view to history more than an attempt to rewrite and correct the view to Islamic history in general. His purpose of theses attempts is to make the Islamic history related to the historical reality of the Islamic cause with all its stages and periods. By that he is confirming basic cases concerning the nature and purpose of this history on one hand and method of dealing with the Islamic historical records on the other hand which then became the base of our  understanding of this history.
The proof is with Abi Al-Barakat Al-Baghdadi
Authors: إبراهيم نعمة , الربيع نبأ
Published: July 2023

Praise be to God alone the Lord of Worlds, Prayer and peace be upon His Prophet and his pure Ahlul-Bait.
Abi Al- Barakat Al-Baghdady occupied a n important position in the history of our Arab Islamic philosophy, he had an original critic ability to which we can hardly find a peer. He comprehended all the different intellectual trends of his period, this is exhibited clearly in his ( Al-Mo`atabar fi Al-Hikmah ) where he put his philosophical project and critical attitude towards his period intellectual trends , this book  had considered all the tiny details of these trends and directions, we can say that it is  the intellectual encyclopedia of Abi Al- Barakat Al-Baghdady period.
Throughout this research, it became clear that Abi Al- Barakat was able to establish the bases of the rational critical method in his ( Al-Mo`atabar fi Al-Hikmah ), this indicates the originality and deepness of this philosopher thought, just like the other Muslim philosophers such as Al-Gazzaly , Averroes and other.
The researchers has many reasons to choose this subject such as :- what had been published  for Abi Al- Barakat is only a small part of his works , he still in need for more and more of the deep study, a number of the researchers had studied his works  before, yet the field of logic is still unstudied, as I believe, hence I decided to study this subject.
The thesis is divided into three chapters , an introduction and a conclusion.
The  first chapter is a an introductory  approach for Abi Al- Barakat Al-Baghdady, it includes the philosopher`s life and works as well as his philosophical method, within the first topic, while the second topic deals with Logic before Abi Al- Barakat Al-Baghdady which is represented by the Greek philosophers, with a brief exhibition for Aristotle Logic, and the Logic for the Philosophers of Islam.

Authors: Lebbar Sophia , Darfaoui Mouna , Omrani Abdelhamid El , Khouchani Mouna
Published: July 2023

Recurrent nasopharyngeal carcinoma (NPC) is a challenging condition to treat, requiring effective strategies due to its aggressiveness and resistance to conventional therapies. Stereotactic techniques, including stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT), have emerged as promising options for managing recurrent NPC. These techniques deliver highly precise radiation doses to the tumor while minimizing damage to surrounding healthy tissues, maximizing tumor control, and reducing side effects. This review explored the current evidence and clinical outcomes of stereotactic techniques in managing recurrent NPC. A systematic review was conducted using PubMed as the primary database, and 58 relevant articles were analyzed. The selected studies demonstrated the efficacy of stereotactic techniques, with high response rates and favorable local control and survival rates reported in various cohorts. However, the review also noted the potential risk of complications associated with stereotactic techniques, including late toxicities such as radionecrosis or hemorrhage. While the studies showed promising results, the level of evidence was primarily based on retrospective analyses and some pilot and prospective studies, highlighting the need for further validation and longer-term follow-up. More research is required to establish optimal protocols, minimize risks, and further understand the role of these techniques in improving patient outcomes.

Authors: B Sathyanarayana Reddy , N Ramya , Govind, Amal , Dudi Saroj R.
Published: July 2023

Introduction: Surgical Site Infections (SSI) are the third most commonly reported nosocomial infections which has an adverse impact on the hospital as well as on the patient. SSI a hospital acquired infection among surgery patients, which in turn delays normal recovery process and increases hospital length of stay and health care costs. Case study: A 34-years-old woman underwent ORIF surgical procedure on 22/3/2023 and developed symptoms like oozing of pus from surgical site on fifth day of post-surgery, fever spikes on same day, increase of pain at surgical site. She was treated with linezolid-600mg-BD a day intravenously and Meropenem-1gm-BD a day intravenously. After 10 days she made eventful recovery and got discharged. Microbiology Examination and Diagnosis: Pus sample collected from surgical site gave rise to growth of Pseudomonas aeruginosa on mac cockney agar medium. Pseudomonas aeruginosa of this particular sample showed resistance to most of the antibiotics that were tested. Discussion: Patient’s conditions like duration of operative procedure (>2 hours), immune-compromised condition like type II Diabetes, obesity, antibiotic prophylaxis and class of wound all these factors becomes risk factors for developing SSI. Conclusion: These infections are more common in elderly patients, patients undergoing emergency surgeries, longer surgical duration (>2 hours), and patients with a high ASA index. In order to decrease incidence of SSI we would have to: a) decrease the duration of the surgeries performed b) focus on regular and intensive drain care c) if a patient has any conditions that can complicate the surgical procedure rule out them first with proper management d) conduct periodic surveillance to keep a check on SSI.

Clinical Audit Report on Mental Health Screening by nurses at a Primary Health Care Centre
Authors: Shaik Noor Fathima , Shaik Abdul Bari
Published: July 2023

Mental health awareness is a vital part of a comprehensive National Mental Health and Wellbeing Strategy for the entire population [1]. The Ministry of Public Health (MOPH) in Qatar along with various stakeholders including PHCC are tasked with promoting and improving the delivery of Mental health services across the country as per Public Health Strategy 2017-2022 and the National Health Strategy 2018-2022 [2, 3]. The Qatar Global Burden of Disease 2010 reveals that major depressive disorder is the most burdensome disease in Qatar as per DALYs [4]. The WHO estimates about 30-50% patients attending primary care with depressive disorder are not detected and nearly two-thirds of people with a known mental disorder never seek help from a health professional due to stigma, discrimination, and negative stereotype [5]. Other reasons include limited time, access, affordability and lack of education and training. It was reported that an average delay between first symptoms presentation and intervention is approximately 11 years, which makes screening important as it allows for early identification and intervention. Recently MOPH launched Ma'ak Educational Program to enhance mental health and wellbeing in Qatar [6]. This can help bridge the gap and lead to better outcomes. Evidence suggests early treatment may also lessen long-term disability and suffering [7]. This Audit is done to review the adherence to mental health screening by nurses at our primary health care center (HC) and suggest measures to improve quality of patient care and health outcomes at PHCC if audit finds any gap in practice. A baseline audit sample of 354 health records was selected from the total volume of patients (18years and above) who were seen at nurses' station at our HC between 11th to 20th January 2023 and reviewed retrospectively against audit specific criterion. This data was then analysed to see how many of them had mental health screening performed using PHQ2 and GAD2 questionnaires. ..

Iceberg Lettuce Reduces the Severity of Gastroesophageal Reflux Symptoms: Two Case Reports
Authors: Hurr Thomas J.
Published: July 2023

Gastroesophageal reflux is a common disease and generally occurs when a portion of the contents of the stomach pass through the lower esophageal sphincter and into the esophagus and returns. If gastroesophageal reflux occurs regularly then symptoms of gastroesophageal reflux disease or GERD can develop. Typical gastroesophageal reflux symptoms (RS) are often defined as heartburn/discomfort or a feeling that stomach contents could reflux into the oesophagus. Gastroesophageal RS are commonly managed by making dietary and lifestyle changes but may also require the use of antacid tablets or proton pump inhibitors (PPIs). Two cases are presented where the effects of consuming iceberg lettuce (IL) on the severity of RS, classified as mild, medium or severe, are reported. It was found for both patients, IL consumed after a meal could resolve mild RS, resolve or reduce the severity of moderate RS, and reduce the severity of severe RS to mild or moderate symptoms, but not resolve them.

The Impact of Semantic Mapping on Reading Comprehension Among Moroccan EFL Students
Authors: Mouchrif Hassan
Published: July 2023

Research indicates a relationship between vocabulary complexity and reading comprehension skills of EFL learners. Expanding vocabulary can improve comprehension, but increasing the number of words may not be enough. Direct vocabulary instruction is less effective than semantic mapping techniques, which involve creating interconnected maps of vocabulary terms to activate readers’ existing background knowledge. This study investigates the efficacy of semantic mapping as a pre-reading strategy for improving reading comprehension of cultural texts among beginner EFL learners in Morocco. A quasi-experimental research design was used, with experimental and control groups assigned according to the Macmillan’s Language Hub placement test. The experimental group was taught through semantic mapping and the control group received direct vocabulary teaching. The experiment lasted for eight sessions, with a pre-test and post-test administered along with individual interviews. Data were analyzed using SPSS and subjected to a repeated measures ANOVA. Results indicate that semantic mapping yielded significant improvements at the inferential level of reading comprehension, but no significant effects were observed at the literal level. Research implications and future directions are discussed.
Translation of Culture-Specific Terms from Arabic into English Between Loss and Preservation
Authors: Makaoui Ismail
Published: July 2023

Undoubtedly, translation is one of the oldest means of communication and a bridge connecting various cultures. In this sense, it stands as an effective tool for intercultural communication. Be it through written literary works or media outlets, translation is unarguably listed as one of the best communication channels. Thus, the present paper tackles the problematic issue that translators encounter while translating some culture-specific words or expressions from Arabic into English. A huge gap between the SL and TL may lead to more difficulties to transfer the message. The difference between Arabic and English in linguistic structures and discrepancies in their cultures sometimes make the process of translation a real challenge. Translation, of course, is not an easy task, but it requires a skilled and knowledgeable translator to make it right. In this paper, the primary concern is to shed light on the issue of culturally-specific terms that may generate obstacles for the translator, as well as to see to what extent these obstacles may affect the translation process. Certain translation strategies and methods that are proposed by some theorists are also addressed as remedy solutions for highly challenging culture-specific words or expressions following the model of Newmark (1988)   and Aixela (1996). The paper concluded that possessing a cultural background of the source text can be extremely useful in cases of cultural-complexity translation.
