Carbon nanotubes and fullerenes offer exceptional mechanical and electrical qualities due to their cylindrical and hollow spherical molecular structures. Their extensive range of applications, which includes field emission displays, impregnated metal composites, battery storage media, and nanoelectronics devices, demonstrates their exceptional adaptability. The combination of simple materials, variable behavior, and simplicity of manufacture makes these materials a focal point of contemporary research. Due to the low bias transmission at a few nanometers, they have a wide range of applications in electronic devices, and finding their potential applications is a complicated process. Due to the fact that the valance and conduction bands are symmetric, they have a straight band gap and can be exploited for optical emission. Three processes, including arc discharge, laser ablation, and chemical vapor deposition, can be used to generate carbon nanotubes (CNTs), although chemical vapor deposition (CVD) is the most used method since it yields CNTs that are more than 98% pure. Multiple chirality of 100% pure MWCNTs results in enhanced optical properties and improved use as a light harvesting material. Using CNT composites and functionalized nanotubes, the dye-sensitized solar cells are constructed. In this brief review, the synthesis of CNT and its application in solar cells are discussed.

The aim of this study was to analyze the effect of circuit body weight training on weight loss and Kizami - Gyaku Zuki's punching skills. The sample of 21 karate athletes aged 17 – 20 years consisted of men: -60 kg, -67 kg, -75 kg, -84 kg, height 167 – 178 cm; and women: -50 kg, -55 kg, -61 kg, height 162 – 170 cm. The body weights in this study were adjusted to the 2024 World Karate Federation (WKF) regulations. However, not all samples could fill all weight classes according to the WKF regulations. The training program is carried out for 4 weeks or 12 meetings, with 3 meetings in one week. This exercise is carried out with an intensity of 50 – 70%, number of sets 3 – 5 sets, number of repetitions 14 – 18 times, recovery between posts is 20 seconds, recovery between sets 120 – 180 seconds. The results of this research are that circuit body weight training has an effect on weight loss and kizami - gyaku zuki punches (sig. 0.000 < 0.05). Then the product moment correlation shows a strong relationship, with a sig value. 0.017 (r = -626) means that the more the athlete's weight increases, the kizami – gyaku zuki punching skill decreases. Variables in body weight and kizami - gyaku zuki skills are very important for a fighting athlete, especially kumite, to be able to compete in the specified class. This research can be recommended for athletes who have a short general preparation period, because this program is only carried out for 4 weeks with 3 meetings in one week.

Therefore, the present study aimed to explore the clinicopathological pattern of CRC in the Sudan with specific emphases in the role KRAS and P53 genes mutations. Methodology: This study was carried out in El-Obeid, North Kordofan state, Sudan, using CRC samples from patients who presented to the Al-Obeid teaching hospital between 2017 and 2022 and had a biopsy for histopathological diagnosis. This series featured everyone who has CRC. Results: The most prevalent CRC subtype is adenocarcinoma, which is followed by mucinous adenocarcinoma and metastatic adenocarcinoma, which constitute 74%, 20%, and 6%, respectively. KRAS mutation was found in 40% patients 48% males and 33.3% females). P53 mutation was found in 46% individuals 43.5% men and 48% females. Positive correlations between KRAS and P53 were found in 26% cases, while negative correlations were found in 40% cases. Conclusion: Many CRC patients in Sudan present at advanced stages of the illness and at a younger age, necessitating early screening measures. CRC patients have been discovered to have KRAS, P53, or both mutations. As a result, precise preventative and therapeutic methods are considered essential.

People of reproductive age are frequently affected with Polycystic Ovary Syndrome (PCOS), a common endocrine disorder with a range of clinical, hormonal, and metabolic features. The goal of this review paper is to give a thorough summary of the clinical presentation, diagnostic criteria, aetiology, epidemiology, and treatment options for PCOS. Between 5% and 20% of women in reproductive age worldwide are estimated to have PCOS. This syndrome is widely known for being complicated, involving both environmental factors and genetic predisposition. Common clinical symptoms include irregular menstruation, hyperandrogenism, and an ultrasound that reveals polycystic ovarian morphology. Although there are other sets of diagnostic criteria, including the National Institutes of Health standards and the Rotterdam criteria, a precise diagnosis is still necessary. Those with PCOS are more likely to develop metabolic problems such as obesity, dyslipidemia, and insulin resistance. An elevated risk of type 2 diabetes, cardiovascular disease, and infertility are among the long-term health consequences. The primary objectives of therapeutic interventions, which are tailored to the patient's presentation and goals and involve both lifestyle modifications and pharmacological therapies, are improvements in hormonal imbalances, metabolic abnormalities, and reproductive outcomes. This study compiles the most recent findings and clinical observations to improve healthcare professionals' comprehension of PCOS.

Hepatic abscess is a suppurative collection developed in a neoformed hepatic cavity as a result of the invasion and multiplication of micro-organisms. The prognosis depends on early diagnosis and rapid treatment. The aim of the study was to determine the clinical, biological, ultrasound and therapeutic characteristics of liver abscesses in children aged between 1 month and 15 years hospitalised in the Paediatrics Ward of the District Hospital in Commune V, Bamako. This was a retrospective descriptive study which took place from January 2017 to December 2020, i.e. a period of 4 years, and a prospective study from January 2019 to December 2020, including all children aged between 1 and 15 years in whom the diagnosis of liver abscess had been confirmed by liver ultrasound. Out of 2756 children hospitalised during the study period from January 2017 to December 2020, i.e. a période of 4 years, 12 patients were diagnosed with liver abscess, i.e. a frequency of 0.43% or 4 cases/1000 admissions, with a female predominance of 58.3%, i.e. a sex ratio of 0.7. The mean age was 57 ± 34 months, with extremes of 16 and 120 months. The main reason for consultation was abdominal pain associated with fever, accounting for 75% of patients. Pus culture was positive for Staphylococcus Aureus in one patient (8%). Amebic serology was positive in 33% of patients. Ultrasound revealed a predominance of single abscesses located in the right lobe of the liver in 42% of patients. However, 92% of patients were cured, with an average hospital stay of 12 days, ranging from 2 to 19 days. Liver abscesses uncommon in our context, an early diagnosis and management can improve the prognosis.

Among gastric malignancies, lymphomas rank as the second most common type, following gastric adenocarcinoma. The majority of gastric lymphomas are either mucosa-associated lymphoid tissue lymphomas or diffuse large B-cell lymphomas. Primary gastric Burkitt lymphoma, is a subtype of non-Hodgkin's lymphoma, represents an exceptionally rare and aggressive malignancy, with only a limited number of reported cases globally. We present the case of a male patient with primary gastric Burkitt lymphoma revealed by digestive hemorrhage. The diagnosis was confirmed by endoscopy and gastric biopsies. The gastric localization of Burkitt's lymphoma is unusual. Our work is a review of the literature on Burkitt's lymphoma in its gastric localization.

Gastrointestinal stromal tumours (GISTs) are rare mesenchymal neoplasms of the gastrointestinal tract and mesentery. They are usually found in the stomach or small intestine but can occur anywhere along the GIT and rarely have extra GI involvement. They are associated with high rates of malignant transformation. Most GISTs present asymptomatically but also present with bleeding, abdominal pain, and rarely gastric outlet obstruction. There have been many risk stratification classifications systems which are calculated based on tumour size, mitotic rate, location, and perforation. They are best identified by computed tomography (CT) scan and most stain positive for CD117 (C-Kit), CD34, and/or DOG-1. The approaches to treating GISTs are to resect primary low-risk tumours, high-risk tumours and further treated with imatinib therapy and unresectable tumours treated with neoadjuvant imatinib 400 mg daily followed by surgical resection and regular follow up by abdominal CT scan.

Plant hormones are chemicals that are present in small amounts, influence and promote the division, growth, and maturation of cells and tissues. Salicylic acid is a phenolic phytohormone and has a function in growth/development, photosynthesis, transpiration, ion absorption, and transport. By interfering with endogenous signals, SA mediates plant defense against pathogens. It strengthens the body's defenses against infections by promoting the production of pathogenesis-related proteins. It affects the systemic acquired resistance (SAR) pathway, wherein a pathogenic assault on one.

The paper aims to provide a balanced understanding of the interplay between economic benefits and ecological imperatives in modern forestry, emphasizing the need for a nuanced approach to herbicide use. Through this exploration, the review contributes to the discourse on harmonizing forest management practices with environmental stewardship.

Wheat (Triticum aestivum L.) is a self-pollinating annual grass which is cultivated as staple crop widely cultivated in the world belong to the family poaceae. Wheat plays a vital role in human and animal nutrition because it is a major source of carbohydrates. Drought is a generally prolonged period of dryness which creates significant damage to crops and prevents their effective growth. It can also refer to a prolonged period of extremely low precipitation, especially one that has a negative impact on growing or living conditions. The nutritional and versatile value of wheat grain recognizes it so important that it can be refined into semolina, flour, and other products such as cookies, bread, pastries, noodles, pasta and couscous also stated that wheat is largely used to make chapatti, cakes and other food products. The germplasm was comprised of test varieties or test treatments and check varieties or control treatments. The field experiment was out by utilizing augmented block design. Parameters like germination %, tillers per plant, canopy temperature, normalized difference vegetation index (NDVI), days to 50% heading, flag leaf area (cm2), days to maturity, plant height (cm) were evaluated. Under drought condition yield/plant had positive and highly significant correlation with number of tillers, seed weight/spike and positive non-significant with NDVI, flag leaf area, days to maturity and thousand kernel weight under drought condition.

Funding is very critical for the sustainability of special education. Funding aids in the realization of special educational objectives. Funding of special education is affected under depressed economy. This paper looked at the concept of funding, concept of depressed economics and the concept of alternatives sources. This paper also discussed various alternatives sources of funding options available for special education in a depressed economy. Relying on secondary data that were collected from print and online publications, the paper identified public private partnerships (PPPs), non-governmental organisations (NGOs), international development agencies, community partnership, donations from individuals and charitable organisations, endowment funds, old boy association partnership as some of the alternatives sources of funding available for funding of special education in a depressed economy. Based on this, the paper recommended that special education managers should embrace public private partnerships (PPPs) model, non-governmental organisations (NGOs) strategy, international development agencies strategy, community partnership strategy, donations from individuals and charitable organisations strategy, endowment funds strategy and old boy association partnership strategy to raise more fund to administer the special education institutions in the economy depressed era.

Objectives: To assess the level of awareness among obstetrical care providers about preeclampsia prevention including risk factors, good practice in aspirin prophylaxis, and to analyze the associated factors. Methods: A cross-sectional study conducted among gynecologists and obstetricians, maternal and fetal medicine specialists, and internal or family medicine physicians working in public or private care centers whom involved in obstetric care in Saudi Arabia. An online-administered questionnaire was designed to assess familiarity of aspirin role in prevention of preeclampsia and fetal growth restriction including proper dose, timing of intake, gestational age to start and discontinuation of treatment as well as the risk factors of PE among set of 13 conditions. An awareness score was calculated and divided into two levels: adequate and inadequate familiarity and knowledge. Practice in PE prevention and attitude towards aspirin use, in addition to participants’ demographic and professional factors, were investigated and analyzed as profound factors. Results: Hundred sixty physicians were participated, 85% were obstetrician/gynecologists and 13.1 were maternal fetal medicine Specialists. Less than half of participants have adequate knowledge and awareness in aspirin role and a minority provided correct answers regarding the recommended aspiring dose, timing of intake, gestational age to start and discontinuation of treatment. However, knowledge about preeclampsia risk factors was relatively acceptable. Maternal fetal medicine specialist and physicians working in teaching hospitals were remarkably with better knowledge compared to their respective counterparts in primary and secondary centers. The existence of institutional guidelines about ASA use in pregnancy did not improve the knowledge level. Conclusion: The overall familiarity and knowledge in that regard was relatively poor, associating misconceptions about the risk factors and substantial gaps regarding the optimal timing and prescribing practice. Formal and continuous medical education curricula should be reviewed to promote good clinical practice in preeclampsia prevention as an essential dimension of maternal and fetal care.

Mathematical culture is an abstract concept in relation to fundamental characteristics in the quality and thinking of math learners. Not only does teaching math help learners obtain rules, methods, and strategies for solving the math problems in the process of math study but it also shows the learners with the reality value of learning math in tight relation to nature and society. In the context of innovations in the General Education Program in Mathematics 2018 and the educational objectives in the new era of Vietnam, teaching mathematical culture to students calls for special interest and determined action. On the basis of fundamental characteristics in the concept of Mathematics and objectives in the General Education Program in Mathematics 2018, we proposed some solutions of teaching Mathematical culture effectively by demonstrating examples in the topic: “Natural logarithm” – 6th grade Math.
