Poor planning and scheduling increase buying, storage, and obsolescence expenses. Material shortages increase labor, machine optimum time, etc. Industrial raw materials, semi-finished items, spares, and consumables have distinct consumption patterns, reorder points, purchase lead times, quantity limits, discounts, etc. To save money, machine learning predicts demand and prepares materials. This study employs ARIMA or Support Vector Machine (SVM) machine learning-based forecasting approaches to forecast materials for less inventory. Feature engineering eliminates seasonality, time series, and external demand and ignores data irregularities, missing figures, and disparities. This approach needs to adapt traits to factors, separate test and training data, and consider many future models to represent the best forecasts. Forecast reliability and consistency were examined for each model. Inventory management systems were evaluated for computational complexity and installation ease and found implementation issues. Both models’ input data and resilience were examined using sensitivity analysis. Accurate prediction SVM and ARIMA predict material demand differently. Meaningful statistics show the optimal model. Performance differences between SVM and ARIMA enhance model selection. Thinking about the execution of high inventory system integration and computational complexity, response surface methodology chooses factorial variables with the highest or lowest responses. Analysis of variance, factor analysis, and effect modeling expansions demonstrated for the response.

Background: Cesarean section (CS) is frequently performed in Egypt. However, it may be associated with significant blood loss, which carries a substantial risk for perioperative morbidity and mortality. Tranexamic acid is known for its hemostatic effects in multiple gynecological and obstetric procedures, including CS. That drug inhibits the conversion of plasminogen into plasmin. Nonetheless, the proper timing of its administration is not clearly elucidated. Objectives: We compared preoperative (PrO) versus intraoperative (IO) administration of tranexamic acid regarding blood loss during CS. Patients and methods: We included 106 pregnant ladies in our prospective randomized trial, who were divided into two equal groups. Intraoperative blood loss was calculated, along with changes in hemodynamics, hemoglobin, and the hematocrit value. Results: Intraoperative blood loss showed a significant decline (p ˂ 0.001) in the PrO group (596.23 mL, compared to 674.53 mL in the IO group). Both study groups expressed no significant difference regarding their preoperative hemoglobin and hematocrit values. However, postoperative laboratory assessment revealed a significant reduction (p ˂ 0.001) of both parameters in the IO group (hemoglobin decreased from 11.9 to 10.68 gm/dl whereas hematocrit decreased from 36.05% to 32.02%). The same group expressed a significant increase in heart rate and a significant decline in mean arterial pressure 30 minutes after the procedure, and these changes persisted till the end of the recordings (p ˂ 0.001). Conclusion: The preoperative tranexamic acid administration is superior to its intraoperative administration, as it leads to less blood loss, hemoglobin changes, and a relatively better hemodynamic profile.

الملخص: يناول البحث بالدراسة والتحليل الالتزامات المالية في اليمن القديم من خلال نقوش الزبور المنشورة، وتوصلت الدراسة إلى أن هناك عددًا من الالتزامات تختلف في مضامينها ونوعيتها، ومن تلك الالتزامات القروض العينية والنقدية والديون والسندات المالية، التي كانت تدون في وثائق رسمية تحمل ديباجة معينة وممهورة بتوقيعات الشهود، فضلًا عن أن بعض الوثائق القانونية كانت تصادق من قبل الجهات الرسمية آنذاك، كما توصلت الدراسة إلى أن أغلب تلك الالتزامات المبرمة كانت تحمل عددًا من الشروط المتفق عليها بين الأطراف المستفيدة من تلك الوثائق، وعلى الرغم من أن تلك الشروط تختلف من وثيقة لأخرى إلا أن أغلبها كانت تتضمن شروطًا ملزمة مثل تحديد الفترة الزمنية، وكتابة تاريخ الوثيقة، وتوقيعات الشهود بالإضافة إلى توقيعات الأطراف المستفيدة من تلك الوثائق، كما أشارت بعض النقوش إلى شروط آخرى كان يتم الاتفاق عليها مثل أخذ الرهونات والضمانات العينية والنقدية وتحديد مقدار الفائدة خاصة في القروض، مع التطرق إلى من كان يقوم بصياغة تلك الالتزامات، ودور المرأة اليمنية القديمة بالقيام بمثل تلك الأعمال القانونية. Abstract: Research by studying and analyzing financial obligations through the published inscriptions of the Psalms, and the study concluded that there are a number of obligations that differ in their contents and quality, and among those obligations are in-kind and cash loans, debts and financial bonds, which were written in official documents bearing a specific preamble and marked with the signatures of witnesses, In addition, some legal documents were approved by the official authorities known among the Yemenis at the time, and the study also found that most of those concluded obligations carried a number of conditions agreed upon between the parties benefiting from those documents, although these conditions differ from one document to another. However, most of them included a number of these conditions, such as specifying the time period, writing the date of the document, and the signatures of witnesses in addition to the signatures of the parties benefiting from those documents. Some inscriptions also referred to other conditions that were agreed upon, such as taking mortgages, in-kind and cash guarantees, and determining the amount of interest, especially in loans.

The green bean crop (Phaseolus vulgaris) is infested with many insects such as whiteflies (Bemisia tabaci). An investigation was carried out to study the insecticidal activity of whitefly (Bemisia tabaci), five pesticides were used, namely Thiamothoxam, Sulfoxaflor, Spirotetramat, Pymetrozine, and Flonicamid, and three commercial natural pesticides, namely Superrego, Topnine, and Bernastar. Pesticides and natural pesticides were sprayed during the two seasons of 2020 and 2021. The obtained results in terms of the reduction rate of the insects' number were as follows: The highest rate of reduction appeared in Thiamothoxam and Sulfoxaflor treatments, where it reached above 80%, while the other pesticides were in the range of 40% to 60%, and the lowest reduction rate was 34.33% and 36.00 % for Bernastar during season 2020 and 2021 respectively. When evaluating the toxicity of these pesticides and natural pesticides against honeybees (Apis mellifera), the pesticides did not reveal any toxicity to honeybees, except for Thiamothoxam, Sulfoxaflor, and Superrego The LC50 and LD50 values against honeybees were 0.2 ppm and 0.000005µg/one honeybee for Thiamothoxam, 4.5 ppm and 0.0001125 µg/one bee for Sulfoxaflor, and 0.95 ppm and 0.00002375 µg /one bee for Superego respectively.

In a recent study, we evaluated the remedial properties of gold nanoparticles (gold NPs) green-formulated by Origanum majorana on spinal cord injury in rats. UV-Vis, FE-SEM, FT-IR, and TEM tests were applied to characterize the recent gold NPs. The IC50 values of O. majorana, gold NPs, and butylated hydroxytoluene were 382, 250, and 165 µg/mL, respectively, against DPPH. In in vivo tests, 40 male rats were grouped into four groups: the sham, intact, control, and gold NP (50 µg/kg) groups. Hematoxylin and eosin staining was done to test the lesions post-injury. To determine the neural conduction recovery, somatosensory evoked potential experiments were carried out. For determining the astrogliosis, the GFAP expression was evaluated. All rats were assessed for behavior outcomes using the Basso, Beattie, and Bresnahan (BBB) scores every week after spinal cord injury onset. The neuroprotective effects of gold NPs caused improvement in the spinal cord injury contusive model in Wistar rats. Delayed responses were reduced significantly and BBB scores were raised significantly in the gold NP group on sensory tests. The highest reduction in GFAP was evident in the gold NP group. The ventral motor neuron number raised significantly and cavity areas reduced significantly in the gold NP group. Electromyography findings indicated notable improvement of hindlimbs in the gold NP (50 µg/kg) group.

Improving the stability of PVC became a task for many research groups to improve its properties and lower plastic pollution. An invented Schiff base was applied as a heat-resistant agent to alter polyvinyl chloride (PVC) behavior under varying temperatures. The efficacy of the Schiff base-treated PVC films in terms of thermal stability was assessed through weight-loss analysis, Fourier transform infrared (FTIR) spectroscopy, an optical microscope, and atomic force microscopy (AFM). The outcomes demonstrated that incorporating the altered PVC extended the polymer's stability duration, consequently lowering its inclination towards degradation. Furthermore, the Schiff base led to a marked decrease in the presence of PVC's conjugated double bonds, consequently reducing weight loss. The enhancement observed can be credited to the Schiff base's strong ability to neutralize HCl and its effectiveness in protecting unstable chlorine atoms within the polymer chains. These alterations, when combined, resulted in a prolonged delay in thermal degradation and alterations in color, affirming the success of the modification method in improving the thermal stability of PVC.

ABSTRACTBackground It has been demonstrated that lactate is a predictive indicator in trauma. It is yet unclear how non-normalization of lactate affects trauma victims.Methods In trauma patients, blood lactate levels were measured at admission and every 2 hours after that. A multivariate logistic regression analysis was conducted to identify the crucial variables to evaluate hospital mortality risk factors.Results 519 patients with trauma were assessed. Male patients (79%, n = 409) who were mostly young (42±20 years old) and had no comorbidities (ASA 1) made up the majority of the patient population. Patients who had normalization of serum lactate in the first 24 hours represented 76% (n = 392) of all trauma patients. Male patient status (OR = 2.2 (1.1–4.6)) and blood alcohol level (OR = 0.64 (0.44–0.91)) were independently linked in a logistic regression model with the failure of serum lactate to normalize in trauma patients over the initial 24 hours. Three variables were independently associated with hospital mortality: a GCS >9 (OR = 0.78(0.61–0.96)), and a pH> 7.37 (OR = 0.0028(0.00066–0.52)) at admission were protecting factors. One of the main risks for death in the pre-field was cardiorespiratory arrest (OR = 62 (2.2–4400)). Hospital mortality was not related to non-normalization of serum lactate in the initial 24 hours (OR = 1.8(0.4–7.9)).Conclusions Although serum lactate at admission is associated to trauma patient prognosis, our study failed to show that non-normalization of serum lactate in the initial 24 hours was a factor that could predict hospital mortality. A future study focusing on normalizing serum lactate in a shorter scale of time could be interesting.

Abstract Background Previous studies have reported conflicting results about the association of vitamin D (VD) level with coronary artery disease (CAD). We aimed to study the association of VD with atherosclerotic CAD in Egyptian individuals. Results We prospectively enrolled 188 consecutive CAD patients with a median age of 55(50–62) years; 151(80.3%) were male. All patients were diagnosed by cardiac catheterization and were compared with 131 healthy controls. VD levels were measured in serum samples of all participants. Compared to controls, CAD patients had a significantly lower median VD level, 14.65 (9.25–21.45) versus 42.0 (32.0–53.0) ng/mL, p

Abstract Background Transcatheter mitral valve replacement (TMVR) using the Tendyne™ valve is regarded as one of the most studied TMVR systems. The first human experience with the procedure was reported in 2013. The present study aims to systemically revise the published literature to document the global experience with TMVR using the Tendyne™ valve. Methods The present review was conducted in line with the PRISMA statement on systematic reviews. Database included in the search process were Scopus, Web of Science and Pubmed. Search was processed using multiple keywords combinations and was adjusted to English literature only. Results We included 26 articles in the final analysis reporting data from 319 patients. Patients recruited by the included studies comprised 192 males (60.2%) and 127 females (39.8%). In the studied patients, mitral annular calcification (MAC) was reported in 107 patients (33.5%). Preoperatively, MR grades 1,2 and 3–4 were reported in 3,5 and 307 patients respectively. Postoperatively, MR grades 1, 2 and 4 were reported in only 12, 3 and 1 patients respectively. Technical success was achieved in 309 patients (96.9%). Follow up durations widely varied among different studies from just days before discharge to 6 years. At the end of follow up, 79 patients died (24.8%) including 52 patients (16.3%) due to cardiovascular causes. Conclusions Management of mitral valve disease using the Tendyne system appears to be a promising minimally invasive option for many high-risk patients with accepted procedural feasibility and safety profile.

This study aims to assess and measure students' performances using course-key performance indicators (course-KPIs) in an academic course at a Saudi university. The approach includes three aspects of assessment (i) integrating course components and correlating course learning objectives with the program learning domain, (ii) course evaluation using rubrics, and (iii) performance mesurement using a scientific method. Moreover, it presents a novel approach for performance measurement of the course learning skills. In this study, a course has been taken to demonstrate how the KPIs are measured for evaluating students' performances. This approach relies on several specific documents that are developed for the course delivery by following the National Qualification Framework (NQF) in Saudi Arabia and the guidelines of the Accreditation Board for Engineering and Technology (ABET). The performance evaluation outcomes are useful indicators that guide the teachers to improve course learning skills. It also helps the teachers in the quality delivery of the courses and ensures continuous improvement in learning and teaching. This study concludes with an emphasis on the measuring performance using course-KPIs which can be adopted for quality improvement for any academic course in higher education irrespective of data size.
