Published: March 2023

The COVID-19 pandemic’s epidemiological and clinical characteristics have been affected in recent months by the introduction of SARS-CoV-2 variants with unique spikes of protein alterations. These variations can lessen the protection provided by suppressing monoclonal antibodies and vaccines, as well as enhance the frequencies of transmission of the virus and/or the risk of contracting the disease. Due to these mutations, SARS-CoV-2 may be able to proliferate despite increasing levels of vaccination coverage while preserving and enhancing its reproduction efficiency. This is one of the main strategies in tackling the COVID-19 epidemics, the accessibility of precise and trustworthy biomarkers for the SARS-CoV-2 genetic material and also its nucleic acids is important to investigate the disease in suspect communities, start making diagnoses and management in symptomatic or asymptomatic persons, and evaluate authorization of the pathogen after infection. Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) for virus nucleic acid identification is still the most effective method for such uses due to its sensitivity, quickness, high-throughput sequencing capacity, and trustworthiness. It is essential to update the primer and probe sequences to maintain the recognition of recently emerging variations. Concerning viral variations could develop that are dangerously resistant to the immunization induced by the present vaccinations in coronavirus disease 2019. Additionally, the significance of effective public health interventions and vaccination programs will grow if some variations of concern exhibit an increased risk of transmission or toxicity. The international reaction must’ve been immediate and established in science. These results supported ongoing efforts to prevent and identify infection, as well as to describe mutations in vaccine recipients, and they suggest a potential risk of illness following effective immunization and transmission of pathogens with a mutant viral.

Published: March 2023

Treatment of cystic echinococcosis of the liver still remains a debatable subject. The method of choice should aim for the total elimination of the parasite with minimum morbidity and mortality. Different approaches have been proposed. Medical treatment as a monotherapy has been abandoned due to the high chances of recurrence and is mostly used as an adjuvant to surgery or minimally invasive methods. Surgical methods are divided into conservative ones, which include cystectomy and partial pericystectomy, and radical ones, total pericystectomy and hepatectomy. Radical procedures are correlated with lower complication and recurrence rates and, therefore, should be attempted when indications are present. On the other hand, conservative surgery can be the first option in endemic areas, performed by non-specialized general surgeons. The development of laparoscopic techniques made their use a possible alternative approach in selected cases. The use of percutaneous treatments is also quite widespread due to their minimally invasive nature. New energy devices seem to play a significant role in the treatment of cystic echinococcosis, although more studies are needed to establish their efficacy. Observation without intervention is an option for inactive uncomplicated cysts.
Linear Codes from Projective Varieties: A Survey
Authors: Vincenti Rita
Published: March 2023

Linear codes can be constructed from classical algebraic varieties or from appropriate subsets of finite geometry by considering projective systems arising from their rational points. This geometric point of view allows to look for linear codes by choosing suitable sets to get immediately length, minimum distance, and spectrum (cf. Lemma 1, Propositions 5, 9, 12, 13, 17). In some cases, it is also possible to build a PD-set or an antiblocking decoding (cf. Propositions 3, 4, 14, Examples of Section 5).
Chronic Constrictive Pericarditis
Authors: Benli Onur
Published: March 2023

Constrictive pericarditis is the result of a chronic inflammation of the pericardium. Chronic constrictive pericarditis is still a rare disease but is being recognized more frequently. It is characterized by fibrous thickening and calcification of pericardium that impairs diastolic filling, reduced cardiac output, and ultimately leads to diastolic heart failure. Clinically, chronic constrictive pericarditis is characterized by dyspnea during exercise, symptoms of right heart failure. Pericardiectomy with complete decortication is the treatment of choice for constrictive pericarditis.

Published: March 2023

Nutritional security can be achieved only with the proper intake of fruits and vegetables. However, on an average 30% of the fruit produce are lost between harvest and consumption due to post-harvest spoilage. About 30–40% of total fruits production is lost after harvest. Main causes of postharvest loss include lack of temperature management, rough handling, poor packaging material, and lack of education about the need to maintain quality. There are many ways in which the post-harvest spoilage is managed. Use of chemicals in post-harvest management has direct effect on the consumers and there is a need for alternative strategies. Use of microbial biological control agents have been successfully adopted for soil borne diseases. Registration and biosafety issues make it difficult to use them against post-harvest diseases. Use of volatile organic compounds (VOCs) from bioagents for the post-harvest management provides an opportunity to explore the use of bioagents without having contact with fruits. Many classes of chemicals are produced as volatiles by microbial agents. This chapter describes the potential of VOCs in managing post-harvest diseases, their characterization and identification, biosynthesis, volatiles reported from bacterial, fungal and yeast bioagents, success stories of their use as potential bioagents.

Authors: Sousa Filipa , Ferreira Domingos , Reis Salette , Costa Paulo
Published: March 2023

Histoplasmosis is an airborne systemic infection, with varied clinical manifestations, from asymptomatic infection to disseminated disease with a deadly outcome. Due to a growing number of immunosuppressed people, this mycosis has become more prevalent and thus, a cause for concern within the medical community. In fact, this fungal infection can be quite serious for children, elderly, people who have had an organ transplant, HIV-positive or people taking immunosuppressants. There has been a limited number of research articles suggesting polymeric, metallic, or lipid micro and nanotechnology-based approaches as a potential way to carry antifungal drugs to treat histoplasmosis. These new drug delivery systems present a variety of means of administration, thereby allowing a more targeted treatment to the lungs, skin, or eyes, according to the infection site. In this review, the aim was to explore these new therapies that have been emerging which hold great potential in comparison to regular antifungal treatments, not only due to their safety but also due to their drug release profile.

Published: March 2023

Renewable energy resources are need of the hour at the current energy scarcity scenario in the world. Scientist and researchers are finding the ways to replace the conventional energy resources with the renewable ones. It is fact that fossils are going to be obsolete in future. One third of global energy is being consumed by the transportation sector. All the amount of this energy comes from the fossils that contain the hydrocarbons in their composition. Efforts are being made to replace the fossils with the renewable energy resources. In this regard, biofuels are emerged as a replacement of the diesel fuels. There are several processes in the engine cylinder from atomization of fuel until the exhaust of gases. One of them is the evaporation of fuel droplets. In the present work, evaporation characteristics of conventional diesel fuel and biofuels is described by comparing them in different working conditions. Modeling of evaporation phenomenon using computational fluid dynamics (CFD) techniques and the effects of in cylinder conditions is also explained. Results show that biofuel droplets show a better evaporation rate at the high operating conditions in the engine cylinder.

Authors: Asare Mavis
Published: March 2023

Objective: Research findings have indicated a link between exercise and cognitive performance of school children. The influence of exercise on executive functioning however, is not conclusive. This study examined the impact of a 3-month exercise intervention on the executive functioning, a form of cognitive functioning, in African youth. Methods: An experimental design was used, including 120 adolescents in junior high school (48 males, 72 females) aged 13 to 18 years (mean age = 14.83 years) in Ghana. Exercise levels and cognitive functioning of the participants were assessed at baseline and also at the end of the intervention. Exercise levels were measured using the Physical Activity Questionnaire for Older Adolescents (PAQ-A) and pedometer; cognitive functioning was assessed with the Raven’s Progressive Matrices test. The participants in the experimental group participated in aerobic exercise, twice a week for 3 months and also met the exercise recommendations of 10,000 steps per day. Results: Post-test results indicated that participants in the experimental group scored higher on cognitive functioning than the control group [45.00 (9.38) vs. 32.62 (9.54)] and the observed difference was significant [F (1, 56) =63.39, p<0.001]. Conclusions: The study found that higher levels of moderate to vigorous exercise improved the cognitive functioning of the students.
Use of TSD, CSS or CLOSE maze to measure spatial navigation, working memory, Reference memory, memory errors, locomotor activity and anxiety-like behavior in Rats
Authors: Aslam Muhammad
Published: March 2023

The Open Field Maze was one of the utmost frequently used platforms for assessment of behavioral profile of model animals. Initially an Open-Field use was defined in Hall and Ballechey’s 1932 paper, “A study of the rat’s behavior in a field: a contribution to method in comparative psychology”. Open Field Test (OFT) was a modest apparatus used in evaluation of limited behavioral profile anxiety, exploration, and locomotion activity. TSD (time space determinant) maze, CSS or CLOSE maze was recently developed in our laboratory aimed to find the cells involved in earlier food seeking behavior in rats given food stimulus in short and long pathway. However, it demonstrates relatively optimal test that provide a various information of behavior ranging from motor activity, anxiety, emotionality, spatial navigation, cognition, memory and memory errors to wide range of exploratory behaviors of tested animal evaluated via TSD maze equipped with video tracking software. A TSD maze comprised of a wall-enclosed area with adequate height prevents the rats to escape from maze. The TSD maze was recently used platform for evaluation of behavioral and neurophysiology of freely exploring animal especially rodents. This procedure will readily become useful to investigate the effect of different pharmacological compounds and toxicants on learning and memory as well as their anxiolytic and anxiogenic effects.

Authors: Thabet Ahmed A. K. , Suroory Siham A.
Published: March 2023

Background: khat is a plant which is cultivated in Yemen and the horn of Africa. The small leaves are chewed by people for their stimulating effects. The mental and physical stimulating effects of khat chewing are due to the sympathemimetic substances in khat. The most important is cathinone.

Smoking is also an increasing health problem in Yemen. The aims of this study, therefore, are to determine the prevalence of khat chewing and smoking habit among Yemeni women in Aden governorate and to find the association between khat chewing and smoking.

Methodology: A cross-sectional study was conducted which involved 250 women from different sectors of society in Aden governorate.

Results: The study showed that the life time prevalence of smoking was 80% while both life time smokers and chewers was 100%. Thirty three percent (33% ) of the life time chewers and 32.7% of the life time smokers have duration of khat chewing and smoking from 10 to 19 years. 15.9% of the ever khat chewers and 19.6% of the ever cigarette smokers have had duration from 30 to 39 years. Also, the study shows that the habit of khat chewing is a very important risk factor in increasing the addiction of smoking with a frequency of 96.9% of smoking during khat chewing, compared to 3.3% of khat chewing without smoking.

Conclusion: The study demonstrated high prevalence of smoking and khat chewing among women in Aden governorate. Also, the study demonstrated the high prevalence of cigarette smoking among chewers.

Floating Point Genetic Algorithm Approach for Optimizing Unstructured Meshes
Authors: Ali Ahmed Abdo
Published: March 2023

This paper presents a method for optimizing unstructured triangular meshes using a floating-point genetic algorithm. A mesh generation algorithm based on a modified advancing front method and sets of heuristic rules are used to generate the initial non-smooth triangular meshes for complex shapes. The developed mesh is then smoothed using a floating-point genetic algorithm that is more flexible than the usual binary genetic algorithms, and can handle non-smooth regions containing several local extrema. Three approaches are used in selecting the fitness function to be optimized in the genetic algorithm, namely, the triangle aspect ratio, the maximum angle at each node of the triangular mesh, and a weighted linear combination of both functions. The genetic algorithm has been tested and validated for a number of test cases covering a wide range of complex geometry applications. The results have shown a high degree of improvement in the quality of the smoothed meshes and an ability to handle non-convex regions.

Published: March 2023

Background: Mitral valve prolapse is a common cardiac disease with frequent complications.

Objectives: To study the prevalence of mitral valve prolapse in healthy Yemenis associated with the prevalence of its adverse sequelae.

Methods: We performed echocardiography for 1164 healthy Yemeni individuals: 615 women and 549 men (mean age ± SD 45.7 ± 10 years).Classical mitral valve prolapse was defined as a superior displacement of mitral valve leaflets at least 2 mm with a maximal leaflets thickness of at least 5 mm during diastasis. On the other hand, nonclassic prolapse was defined as displacement of more than 2 mm with a maximal thickness of less than 5 mm.

Results: 74 subjects (6.3 percent) had mitral valve prolapse, 40 (3.4 percent) had classic prolapse and 34 (2.9 percent) had nonclassic prolapse. None of the patients with prolapse had a history of heart failure nor anyone had atrial fibrillation except one patient (1.3 percent) had cerebrovascular disease and two patients (2.7 percent) had syncope, as compared with unadjusted prevalence of these findings on the individuals without prolapse of 0.0, 0.0, 0.0 and 1.3 percent, respectively. Chest pain, dyspnea and electrocardiographic change frequencies were similar between two groups.

Conclusion: The prevalence of mitral valve prolapse in adult Yemenis was 6.3 percent, which is similar to the results of other studies in different countries but with low prevalence of adverse sequelae in comparison to those studies.

Polymer Nano composites and lithium polymer electrolytes are always scientifically speaking. It is formed by dissolving Multiwalled carbon nanotubes(MWNT) and lithium salt in poly(ethylene glycol), poly(vinyl alcohol) blends with the aim of developing new types of polymer composite characterized by enhanced thermal stability, as well as by improved electrical properties. The interaction of the MWNT and LiNO3 with the polymer blend were confirmed by a Fourier transform infrared (FTIR) spectroscopy study. The thermal properties of the polymer blend with the MWNT were carried out by means of differential scanning calorimetry (DSC). It is evident from DSC that the polymer/MWNT had a decreased of Tm and heat crystalline fusion(∆Hc) with of increased MWNT. Scanning electron microscopy is used to study the dispersion of the MWNT and LiNO3 in the polymer blend. Electrical conductivity was observed for PVA/PEG/MWNT containing 0.40 wt % MWNT was 7.98 X10-7S/cm where the PVA/PEG was 8.31 X10-8S/cm also electrical conductivity of PVA/PEG/LiNO3 containing 40wt % was 1.02 X10-7S/cm. Relative changes in the conductivity of blends with different concentrations and temperatures are analyzed.

Objectives: This descriptive study aims to evaluate surgical management of pancreatic cancer at Al-Thawra Modern General Hospital-Sana’a, Yemen and to provide reflection of clinical presentation and risk factors for pancreatic cancer in Yemen.

Methodology:The study was a retrospective descriptive study of forty four patients with pancreatic cancer subjected to surgical treatmentat Al-Thawra Modern general hospital, Sana’a, Yemen over a period from July 2009 to January 2012.

Results: Total numbers of patients were 26 males and 18 females with mean age of 62 years. Pancreatic cancers were located in the head of pancreas in 84%, periampulary in 9.1% and 6.8% in the body & tail. Pancreatic cancer was found to be more frequent among smokers 75%. Most patients were presented with obstructive jaundice 81.8%, vague abdominal pain 66% and weight loss 27.3%.Abdominal computer tomography (CT) scanning was done for all cases. Clinical presentation and the accuracy of CT scan in diagnosis and staging of pancreatic cancer are approximately similar to that reported in other countries 81% and 82%.

Curative surgical resections were done for 26 cases while palliative surgeries were performed for 18 irresectable cases. Most of complications and all mortality cases occurred among patients who underwent pancreaticoduodenectomy (Whipple operation). However, we reported a higher mortality rate (17.4%) after Whipple operation at Al- Thawra Hospital-Sana’a than other high volume centers.

Recommendations: This study recommends multidisciplinary approach for managing pancreatic cancers with liberal use of abdominal CT scan for diagnosis and staging of pancreatic cancers in suspected cases. Meticulous surgical techniques are advised in improving the surgical management of pancreatic cancer with minimal complications. Further extended studies to evaluate the different factors affecting surgery for pancreatic cancers and to provide basis for improvement in the surgical management of pancreatic cancers.

Background and objectives: Standard reverse island sural artery flap is the most common usage for distal third defects of the leg. However many authors reported 36 % complication rate mainly partial or complete flap loss , that is attributed to venous congestion. Delayed reverse sural artery flap in two stages with skin pedicle technique is reliable and less complicated. In this study was compare between the results of both techniques.

Patients & Methods: The study included forty patients presented to AL-Wahda University Hospital and 48 Military Hospital , after trauma of lower leg with complete loss of soft tissue and exposure of underlying structures ,within periods Oct 2013 to May 2017. The patients were thirty male and ten female , their age ranged between fifteen to sixty years old . Reverse island sural artery flap was used in twenty patients, while delayed sural artery flap was used in twenty patients too.The results of both techniques were compared.

Results: In our study the standard reverse island sural artery flap is good option for reconstruction of lower leg , ankle and malleoli defect ,which is performed in twenty patients , the partial necrosis occur in 20% patients and three cases with flap failure ,the venous congestion occur in 35% of patients In this study, we performed reconstruction of the lower leg, heel , and malleoli in another twenty patients by delayed reverse sural artery flap with skin pedicle technique, the flap necrosis occur only in one case and partial flap necrosis occur in two cases only, in comparison with standard technique of reverse island sural artery flap, the venous congestion occur only in four patients 20% , two cases recovering the congestion by leg

elevation and improving the patients hydration , and two cases of venous congestion progressive to partial flap necrosis. Partial necrosis occur in two cases, complete flap necrosis occur in one case and 95% of patients satisfaction in discharge.

Conclusion: The delayed reverse sural artery flap with skin pedicle is very important to avoid of venous congestion and flap failure , especially in old patients , DM , and in patients with peripheral vascular diseases. The goal of our study were achieved , and the patients improved functionally and attained their routine activity. By this technique and modification, make the delayed sural artery flap the first choice in reconstruction of the lower third defect of leg , heel and ankle. and is less postoperative venous congestion and flap failure. Delayed sural artery flap in two stages with skin pedicle technique is convenience and less complication particularly for old patients with diabetes mellitus and peripheral limb ischemia or venous insufficiency.

بلغت العمارة التقليدية بصنعاء حداً كبيراً من الازدهار نتيجة تناقل الخبرات عبر الأجيال المتعاقبة, التي تطورت نتيجة التطبيق العملي - الموقعي - لسلسلة من التجارب السابقة على مر السنين, وهذه العمارة لم تختص بجيل معين بدليل ظهور مباني متجانسة تحمل طابع مشترك, تؤكد المجهود الإبداعي للعمل الجماعي بعيداً عن الفردية المطلقة التي تفتقر إلى الرؤية الكاملة, فالعمارة التقليدية بصنعاء هي وليدة تداخلات الفكر الفردي والذاكرة الجماعية. وحتى تكون عمارة الحاضر نتاج لعمارة الماضي وتشكل جسراً إلى عمارة المستقبل فإنه لابد من الربط بين القديم والجديد, وفتح آفاق جديدة لمحاولة قراءة الماضي بعيون معاصرة. أما ما يحدث اليوم في العمارة المعاصرة فيؤكد الفردية المطلقة في أتخاذ القرار بدليل ظهور مباني غير متجانسة, لا تجمعها بصمة مشتركة. وقد ظهر ذلك جلياً على واجهات الأبنية المعاصرة عند التعامل مع الموروث التقليدي وعلى وجه الخصوص العناصر التشكيلية المعلقة (المشكلة) ولذلك يهدف هذا البحث إلى دراسة العناصر التشكيلية التقليدية المعلقة بأسلوب علمي ومنهجي للاستفادة منها عند صياغة واجهات المباني المعاصرة لتحقيق التواصل الحضاري. ومن ثم دراسة الوضع الراهن للعناصر التشكيلية المعلقة على واجهات الأبنية المعاصرة. كنتاج نهائي لعملية التصميم لتوضيح السلبيات التي ظهرت عليها من خلال رصد مظاهر التطور والتغير نتيجة التعامل السطحي مع عناصر التشكيل التقليدية المعلقة (الهدف). ولتحقيق ذلك الهدف تم تقسيم البحث إلى ثلاثة محاور رئيسية تسلسلت لتحقيق هدفه. بحيث خُصص المحور الأول من البحث (الإطار النظري): لشرح المشكلة البحثية مع التوضيح ببعض الأمثلة. بينما خُصص المحور الثاني (الدراسة الميدانية): لدراسة عناصر التشكيل التقليدية المعلقة لتوفير المعلومات الكافية عنها التي تمكَّن من توظيفها بالشكل المطلوب عند صياغة واجهات المباني المعاصرة لتحقيق التواصل الحضاري, وبالتالي الاستفادة منها عند عمل الدراسة التحليلية للوضع الراهن. أما المحور الثالث والأخير (الدراسة التحليلية): فقد خُصص لتحليل الوضع الراهن للعناصر التشكيلية المعلقة التي ظهرت على واجهات الأبنية المعاصرة, لتوضيح كيف أصبحت تلك العناصر وكيف تم التعامل معها, مع استعراض العيوب والمشاكل التي ظهرت فيها, بالإضافة إلى تحليل تطور وتغير العناصر التقليدية التشكيلية المعلقة على واجهات الأبنية السكنية المعاصرة بصنعاء كنتاج نهائي لعملية التصميم. ولذلك فإن البحث يعد إضافة علمية جديدة للدراسات السابقة التي أهتمت بموضوع التواصل الحضاري والحفاظ على الهوية المحلية في التشكيل.
"TRANSLATION AS A COMMUNICATIVE ACTIVITY IN TEACHING TECHNICAL ENGLISH "
Authors:   University of Medicine, Pharmacy, Science and Technology of Tîrgu Mureş, Ban Andreea
Published: March 2023

This paper intends to demonstrate that translation combines both form and meaning, both proficiency and performance. Due to this aspect, we can say that translation is an ideal exercise in a language teaching environment, supporting, as a consequence, the communicative method to compensate for its failure to concentrate on form, despite the fact that it remains a communicative activity by definition. It will also be determined that engineering students use translation so as to be able to manage the new information in technical field while also considering that it simplifies their learning.
"IM VIRTUELLEN SPRECHZIMMER. DIE INTERAKTIVE ONLINE-KOMMUNIKATION IM DAF-UNTERRICHT, FACHSPRACHE MEDIZIN "
Authors:   „Victor Babeș” University of Medicine and Pharmacy, Kohn Daniela
Published: March 2023

Die digitale Kommunikation öffnet für den zeitgemäßen, handlungsorientierten DaFUnterricht immer wieder neue Möglichkeiten, stellt ihn vor weiteren Herausforderungen und bringt weniger behandelte Themen im Fokus. Die mit der Erweiterung des GER (2018) entwickelten neuen Deskriptoren zur interaktiven Online-Kommunikation, geboren aus der Notwendigkeit einer sich ändernden Wirklichkeit gerecht zu werden, wirken sich kreativ und motivierend auf den konkreten Sprachunterricht aus. Um den DaF-Unterricht für Mediziner so realitätsbezogen wie nur möglich zu gestalten, ist die Entwicklung von Übungstypen zur interaktiven Online-Kommunikation angebracht. Auf das Arzt-Patienten-Treffen im virtuellen Sprechzimmer und nicht nur sollen die (angehenden) Mediziner auch im Sprachunterricht vorbereitet werden.
