Attributing the Electrical Conductivity into Asphalt Composite Using Kaoline-Dominant Mixture Clays

تمتلك مخاليط الإسفلت إمكانات كبيرة كموصلات كهربائية للعديد من الوظائف في مجال الاستشعار الذاتي والاستشفاء وجمع الطاقة. تتحكم التوصيلية الكهربائية (EC) في صب الخرسانة الإسفلتية إلى مرحلة ذات أولوية لمثل هذه العروض المقدمة، مع مراعاة بعض الإضافات التي تقلل من تلف المواد الأساسية مع مرور الوقت. تستخدم اختبارات الموصلية الليفية سابقًا في توصيل خليط الإسفلت. هناك الآن حاجة للتخفيف بسبب التغيير المفاجئ في منحنى ER المقاومة الكهربائية لظروف الترشيح للمخاليط الاسفلتية، مع مراعاة الانتقال المفاجئ من قيم المقاومة الكهربائية (ER) إلى مرحلة التوصيل الكهربائي (EC). يعتبر وجود الخلائط الطينية الفعالة لتخفيف عيوب التغيرات المفاجئة صديقة للبيئة. لذلك، تبحث هذه الدراسة عن ناتج حيث كفاءة التغليف المستخدمة عن طريق توجيه التوصيل الكهربائي (EC) من الخرسانة الإسفلتية فقط عن طريق إضافة محتوى معين من محتوى البنتونيت في خليط الكاولين المهيمن بين الكولين-البنتونايت0.4 الى الكولين– البنتونايت 0.1 (KB0.1) إلى و’ و(0.4 الى (الكولين-البنتونايت (الكولين-البنتونايت 0.1)   التي تتميز بخصائص جيوفيزيائية مختلفة ومعلما (0.4 الى (الكولين-البنتونايت (الكولين-البنتونايت 0.1) لذلك، فان ثمانية أنواع المختبرة والمختلفة من خليط الطين جيوتقنية مختلفة. يتم تقييم قيم ER بواسطة عينات مختلطة من الأسفلت التي تحتوي على محتويات مختلفة من خليط الطين المهيمن..Asphalt mixtures have great potentials as electrical connectors for many functions in the field of self-sensing, hospitalization and energy collection. Electrical conductivity (EC) controls the pouring of asphalt concrete to a priority stage for such presentations, taking into account some additives that minimize damage to basic materials over time. Previously fibre conductivity tests are used in the conductivity of the asphalt mixture. There is now a need for mitigation due to the sudden change in the ER electrical curve of the filtration conditions of the down mixtures, considering the sudden transition from the electrical resistivity (ER) values ​​to the conduction phase (EC). Efficient clay mixtures to relieve defects of sudden changes are considered eco-friendly. Therefore, this study looks for an output where encapsulation efficiency used by directing the electrical conductivity (EC) of asphalt concrete only by adding a specific content of bentonite content in the kaolin-dominant mixture between (KB0.1) to (KB0.4). Therefore, eight different types of clay mixture KB0.1 to KB0.4 and Kaolinite 0.9-Sand 0.1 to KS0.4 have different geophysical properties and different geotechnical parameters. EC values. ER values are evaluated by asphalt-mixed samples containing different contents of the dominant K-clay mixture

Focal and non-focal epilepsy localization: a review

The focal and non-focal epilepsy is seen to be a chronic neurological brain disorder, which has affected ≈ 60 million people in the world. Hence, an early detection of the focal epileptic seizures can be carried out using the EEG signals, which act as a helpful tool for early diagnosis of epilepsy. Several EEG-based approaches have been proposed and developed to understand the underlying characteristics of the epileptic seizures. Despite the fact that the early results were positive, the proposed techniques cannot generate reproducible results and lack a statistical validation, which has led to doubts regarding the presence of the pre-ictal state. Various methodical and algorithmic studies have indicated that the transition to an ictal state is not a random process, and the build-up can lead to epileptic seizures. This study reviews many recently-proposed algorithms for detecting the focal epileptic seizures. Generally, the techniques developed for detecting the epileptic seizures were based on tensors, entropy, empirical mode decomposition, wavelet transform and dynamic analysis. The existing algorithms were compared and the need for implementing a practical and reliable new algorithm is highlighted. The research regarding the epileptic seizure detection research is more focused on the development of precise and non-invasive techniques for rapid and reliable diagnosis. Finally, the researchers noted that all the methods that were developed for epileptic seizure detection lacks standardization, which hinders the homogeneous comparison of the detector performance

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
