There is a seasonal factor, storage risks, supply and demand for the commodity. Commodities are frequently traded in financial markets and can be traded immediately or their derivatives traded in the financial market. The most common types of traded commodities are agricultural commodities, metals, and energy products. Market risk management is common in most companies around the world, but the focus is usually around risk management of price risks, quantity risks, cost risks, and regulatory risks.
In order to model commodity prices, descriptive analysis was used to estimate future commodity prices, and the components can be combined with criteria of central tendency and their relationship with time.
The research found that risk management of all types - prices, quantity, cost, and regulation - has a significant impact on determining the price of wheat in commodity markets, and it has an impact on the time frame
Nommo: Self- Naming and Definition of Africana Woman in Haile Gerima’s Child of Resistance
Get PDFThis article examines the concept of Nommo, which has African roots, within the film Child of Resistance, by filmmaker Haile Gerima of African descent in 1972, emphasising its significance for the self-naming and self-definition of Africana women. It explains the rationale behind analysing Gerima\u27s work from an African womanist perspective by investigating the insights that male filmmakers provide on African women\u27s cinematic representation. By examining particular monologues, scenes, and narrative elements, this article underscores how Nommo connects with the film\u27s representation of African-descent women\u27s self-naming and self-definition. It illustrates the empowerment and resistance within the character’s narrative and aims to enhance the conversation about the complexities surrounding gender and the representation of Africana women in cinem

Antibacterial Resistance Patterns of Urinary Escherichia coli Isolates in Taiz City, Yemen
No full textBackground: Antibacterial resistance is a major threat to health, leading to reducing the efficacy of antibacterial agents against infections caused by bacteria. The most causative of bacterial UTIs, especially in Yemen, is E. coli bacteria.
Objective: The current study aimed at evaluating the percentage rate and potential causes of isolated urine E. coli resistance to some conventional antibacterial drugs in Taiz city, determining which is the most effective, and comparing the results with other studies.
Methods: Thirty urine-isolated E. coli from laboratories in Taiz City, Yemen, were collected, and susceptibility tests to determine the E. coli resistance against some conventional antibacterial drugs were performed. After incubation for 24 hours, the diameter of the inhibitory zones was measured, and the results were recorded. Finally, the average and percentage rates were calculated.
Results: The result was as follows: Highest susceptibility to nitrofurantoin (90% S), with no resistance (0% R). Complete resistance to cefotaxime (100% R), contrasting sharply with ceftriaxone (26.7% R). Alarming levofloxacin resistance (56.7% R). Intermediate sensitivity to co-amoxiclav (56.7% I), suggesting dose-dependent efficacy. High resistance (56.7% R) with low sensitivity (33.3% S) to co-trimoxazole.
Conclusion: In Taiz City, the current study demonstrates E. coli resists the conventionally used antibiotics that were previously considered the most effective antibiotics used for its UTIs, particularly cefotaxime (100% R) and co-trimoxazole (56.7% R). Nitrofurantoin remains highly effective, while ceftriaxone and levofloxacin have variable susceptibility
The Influence of Social Media Content on Teeth Whitening Practices among Adults in Taiz, Yemen
No full textالملخصالخلفية: أصبح تبييض الأسنان أكثر شيوعًا بين البالغين في اليمن، ويعود جزء من ذلك إلى تسويق منتجات وإجراءات التجميل عبر وسائل التواصل الاجتماعي. ومع ذلك، لم تجرَ أي دراسة سابقة حول هذا الموضوع في اليمن.الأهداف: تقييم تأثير محتوى وسائل التواصل الاجتماعي على سلوكيات تبييض الأسنان، ومستوى الوعي بالمخاطر، وأنماط استخدام المنصات المختلفة بين البالغين في مدينة تعز، اليمن.المنهجية: أجريت دراسة مقطعية شملت 398 مشاركًا من البالغين (≥18 سنة) في مدينة تعز. جُمعت البيانات باستخدام استبيان مُهيكل تضمّن المعلومات الديموغرافية، واستخدام وسائل التواصل الاجتماعي، والوعي بتبييض الأسنان، والممارسات المتبعة، والتصورات حول المخاطر. جرى تحليل البيانات باستخدام الإحصاءات الوصفية، واختبار كاي تربيع، ونسبة الأرجحية (OR) عبر برنامج SPSS.النتائج: أفاد أكثر من ثلثي المشاركين (73.4%) باستخدامهم لواحدة على الأقل من تقنيات التبييض، وكان معجون الأسنان المبيّض والطرق المنزلية الأكثر شيوعًا. ذكر أكثر من نصف المشاركين (57.8%) أن قرارهم بتجربة التبييض تأثر مباشرة بمحتوى وسائل التواصل الاجتماعي. كما أن الوعي بالمخاطر المحتملة (75.9%) لم يمنع من ممارسة التبييض. وُجدت علاقة معنوية بين تأثير وسائل التواصل وسلوكيات التبييض (p<0.001)، في حين أن الاستخدام المكثف (أكثر من 4 ساعات يوميًا) ارتبط بانخفاض احتمالية التبييض مقارنة بالاستخدام المتوسط (p=0.0002). لم تُظهر الفروق بين الجنسين دلالة إحصائية، بينما كان طلاب البكالوريوس أكثر ممارسة للتبييض مقارنةً بمجموعات التعليم الأخرى (p<0.001).الاستنتاج: يتأثر سلوك تبييض الأسنان بين البالغين في مدينة تعز بشكل واضح بوسائل التواصل الاجتماعي. وعلى الرغم من إدراك المخاطر، لا يزال الكثيرون ينخرطون في ممارسات قد تكون ضارة. تؤكد هذه النتائج الحاجة الملحّة لأن تقدم السلطات الصحية وأطباء الأسنان معلومات دقيقة قائمة على الأدلة عبر منصات التواصل الاجتماعيBackground: Teeth whitening is becoming increasingly popular among adults in Yemen, and part of this is the social media marketing of cosmetic products and procedures. Nevertheless, no research has studied this point in Yemen.
Objective: To assess how the content of social media affects teeth whitening behavior, awareness of risks, and use of various platforms among the adults in Taiz, Yemen.
Methods: A cross-sectional study was carried out among 398 subjects older than 18 years in Taiz. Data were collected with a structured questionnaire including demographics, social media use, whitening awareness, practices, and perceptions of risk. Descriptive statistics, chi-square, and odds ratio were calculated using SPSS.
Results: More than two-thirds of participants (73.4%) had used at least one whitening technique, principally whitening toothpaste and home whitening. More than half (57.8%) reported being directly influenced by social media in their decision to try whitening. Awareness of potential risks (75.9%) did not limit participation in whitening practices. The influence of social media was significantly correlated with whitening behavior (p<0.001), whereas heavy users (>4 h/day) were less likely to whiten than moderate users (p=0.0002). Gender differences were not significant, but undergraduates were more likely than other education groups to whiten (p<0.001).
Conclusion: Whitening behaviors in adults in Taiz are strongly affected by social media. People still engage in risky behaviors even though they are aware of them. These conclusions are important, as they reflect that health authorities and professionals in the field of dentistry have to provide clear and evidence-based messages via social media
The Influence of Age and Gender on Hematological and Hemostatic Parameters among Healthy University Students in Aden, Yemen
No full textBackground: Hematological parameters are vital indicators of health, influenced by demographic factors.
Objective: This study aimed to investigate the association between age and gender with hematological and hemostatic parameters in a cohort of Yemeni university students.
Methods: A cross-sectional study was conducted on 100 apparently healthy students. Data on age and gender were collected via questionnaire. Venous blood was drawn for Complete Blood Count (CBC), Prothrombin Time (PT), and Partial Thromboplastin Time (PTT) analysis using automated analyzers. Statistical analysis was performed using SPSS.
Results: Significant gender-based disparities were observed. Females exhibited a markedly higher prevalence of abnormal hemoglobin (Hb) levels (58.1%, p=0.0001) compared to males (3.5%). Abnormalities in red blood cell indices (RBCs, MCHC) and platelet (PLT) count were also more common in females, though not always statistically significant. Regarding age, the 18-21 years group showed the highest prevalence of abnormalities suggestive of nutritional deficiencies, specifically in Mean Corpuscular Volume (MCV) (75.9%) and Mean Corpuscular Hemoglobin (MCH) (82.8%). On the other hand, we found that a prolonged APTT was most common in the small group of participants aged 26-29 years (88.9%, n = 9).
Conclusion: Gender significantly influences hematological status, with females showing a higher susceptibility to anemia. Age also affects certain hematological indicators, as mild coagulation changes may emerge in the late twenties, while younger individuals are more prone to nutritional deficiencies. Regular screening and targeted nutritional interventions are recommended for these at-risk populations
DELINEATION OF GEOLOGICAL BOUNDARY IN IDI-EMI AND ENVIRONS, SOUTHWESTERN NIGERIA USING ELECTRICAL RESISTIVITY METHOD
No full textAbstract— Old geological maps in areas with complex rock formations often lack accuracy, risking misinformation, especially where lithological boundaries are subtle. This study integrates Vertical Electrical Sounding (VES) and 2D electrical imaging to improve subsurface mapping in the Idi-Emi area, southwestern Nigeria. The approach successfully identified three terrain types—sedimentary, transition, and basement complex—each with distinct resistivity and layer thickness ranges. The topmost geoelectric layers showed resistivities of 42–634 Ωm and thicknesses of 0.6–1.9 m across these terrains. New geological boundaries were delineated, refining the existing map and aligning with the Dahomey Basin framework. The enhanced geological model provides critical insights for groundwater aquifer delineation, hydrogeological exploration, and controlling illegal mining activities in the region. This integrated geophysical method demonstrates a valuable approach for accurate subsurface characterisation in geologically complex terrains
Leveraging Artificial Intelligence And Statistical Methods For Evaluating Geotechnical Properties Of Lateritic Soil In Road Construction: A Case Study On The Umuahia-Ikot Ekpene Road
No full textGeotechnical properties of lateritic soils are critical for road construction, influencing subgrade stability and pavement performance. This study investigates these properties along the Umuahia–Ikot Ekpene Road, with a focus on predictive modeling and variable importance. Four locations were sampled at depths of 150 mm, 300 mm, and 450 mm. Key properties, including moisture content, particle size distribution, Atterberg limits, compaction characteristics, and California Bearing Ratio (CBR), were analyzed. Moisture content ranged from 10.8% to 13.0%, with Locations A (12.2%) and C (12.8%) exhibiting the highest values. All soils were classified as well-graded, with gravel content varying from 12.5% to 16.0%. Atterberg limits indicated medium plasticity, with plasticity index values between 12% and 14%. Maximum dry density (MDD) ranged from 1795 to 1850 kg/m³, Optimum Moisture Content (OMC) from 10.8% to 12.1%, and degree of compaction from 95% to 99%. Unsoaked CBR values were 24-31%, and soaked CBR values were 17-23%. Lasso Regression outperformed other models (Linear regression, ridge regression, decision tree regressor, gradient boosting regressor, support vector regressor and random forest regressor) in predicting CBR, achieving R² values of 0.86 (unsoaked) and 0.98 (soaked). Feature importance analysis highlighted the key soil properties driving CBR variations while sensitivity analysis reveals that MDD (kg/m³) has a significantly greater impact on the predicted soaked CBR values compared to moisture content (%). The results suggest that these lateritic soils possess moderate strength, making them potentially suitable for subgrade materials. However, stabilization is likely required for sub-base or base layers in road construction
