High demand for asphalt binders in road construction verifies the need of finding alternative materials through asphalt pavement recycling. This paper investigated the impact of different rejuvenators on the performance of an aged asphalt binder. Virgin Olive oil, virgin cooking oil, waste cooking oil, virgin engine oil, and waste engine oil were added to a 30/40 penetration grade aged asphalt binder at a fixed oil content of 4% for all types. The wet method was used to blend the rejuvenators and aged asphalt binder. The physical, rheological, and chemical properties of the rejuvenated asphalt binder were evaluated using several laboratory tests which include penetration, softening point, bleeding, loss on heating, storage stability, penetration index, ductility, viscosity, dynamic shear rheometer, and Fourier transform infrared spectroscopy. The outcomes of the physical properties showed that the olive, waste, and virgin cooking rejuvenators can restore the aged asphalt binder to a penetration grade of 60/70. In contrast, the virgin and waste engine oil required a more quantity of oil to rejuvenate the aged asphalt binder. A sufficient amount of rejuvenator could regenerate the (G*/sin δ), (δ°), and (G*) for the aged asphalt binder. The addition of virgin olive and cooking oils in aged asphalt led to a rutting issue. No chemical reactions were observed with the addition of rejuvenators but they give an impact on reducing the oxidation level of the aged asphalt binder. As a result, further research should be performed on waste cooking oil given that it is inexpensive and provides excellent performance results. Doi: 10.28991/cej-2021-03091669 Full Text: PDF

Published: March 2021

Childhood obesity is a major public health concern around the globe as it is associated with adverse consequences such as psychological problems, lower educational attainment, and a high risk of health challenges later in life. The study investigated the prevalence of obesity and its socio-psychological effects on primary school children in the Cape Coast Metropolis, Ghana. Interview schedule and interview guide were used to collect primary data from 317 pupils and 24 teachers respectively from public and private schools in 2018. Microsoft Excel software (version 2013) was used to analyse quantitative data while content analysis was used for qualitative data based on themes. The result indicated that the overall prevalence rate was five percent. Prevalence of obesity was higher in private schools than public schools while that among male pupils was higher than their female counterparts. Pupils of age 11 years were at higher risk than those at age nine years. The socio-psychological effects on the affected children included stigmatization, exclusion from taking part in some competitive activities, inactive and often slept during lessons. The school authorities should collaborate with the Metropolitan Directorates of Education and Health to manage obesity in the schools. They could invite health experts to educate school management, teachers, pupils, and parents on support systems for managing childhood obesity.
Влияние социокультурных факторов на финансовое развитие

Published: March 2021

<span>В работе оценивается степень воздействия ряда социокультурных факторов, основу которых составляют переменные Хофстеде, на финансовое развитие. Используя межстрановой анализ, авторы выявили три социокультурных параметра, которые имеют значимое влияние на Индекс финансового развития, использованный в качестве интегральной оценки национального финансового развития: индивидуализм, терпимость (допустимость) и долгосрочная ориентация. На основании полученных результатов сформулированы рекомендации по корректировке государственного влияния на социокультурные факторы в Российской Федерации. На наш взгляд, необходимо сохранять долгосрочную ориентацию как преимущество и преодолевать недостаточность терпимости и индивидуализма. Так как финансовое развитие способствует экономическому росту и преодолению неравенства, такая корректировка социокультурных параметров (в целом крайне инерционных) будет в долгосрочной перспективе положительно воздействовать и на параметры социально-экономического развития России.</span>

<p class="_1Vvodka">Хотя новые идеи в науке вырабатывают индивиды, наука является коллективной деятельностью. Общение ученых<span class="myHorizontalScaleForEmDashSpaceBefore"> </span>–<span class="myHorizontalScaleForEmDashSpaceAfter"> </span>важная часть их работы. В естествознании исследователи общаются по поводу своих контактов с объектами исследования, которые принимают в естественных науках форму экспериментов. Один из основателей исходного американского институционализма, Джон Коммонс, обсуждал со своими коллегами и студентами факты, источником которых были контакты с экономическими акторами, контакты, которые были функциональным аналогом экспериментов в естествознании. Так как регулярности в социальной сфере проистекают из того, что акторы следуют в своем поведении определенным правилам, выявление этих правил здесь равносильно выявлению регулярностей, чему и служили контакты исследователей с акторами. Эта исследовательская традиция, активно практиковавшаяся в США между двумя мировыми войнами, была подавлена во времена маккартизма. Была восстановлена, усилена и технически (математически) усовершенствована старая традиция экономической науки, возникшая в университетах как продолжение и замена моральной философии, тесно связанной с теологией.</p><p class="_1Vvodka">В рамках этой традиции общение между учеными происходит не по поводу контактов с объектами их исследования, а по поводу абстрактных теоретических конструкций. Это позволило таким рефлексирующим о своей профессии экономистам, как Дейдра Макклоски и Арьо Кламер, утверждать, что экономическая наука есть не что иное, как разговор (conversation) или риторика. Продолжая эту мысль, я утверждаю, что при отсутствии у экономистов-теоретиков информации о контактах с их объектами исследования, общение между ними (conversation), которое, в частности, принимает форму публикации статей, неизбежно становится схоластической риторикой.

A Canadian perspective on the revised 2020 ASHP–IDSA–PIDS–SIDP guidelines for vancomycin AUC-based therapeutic drug monitoring for serious MRSA infections
Authors: Stewart Jackson J , Jorgensen Sarah CJ , Dresser Linda , Lau Tim TY , Gin Alfred , Thirion Daniel JG , Nishi Cesilia , Dalton Bruce 
Published: March 2021

Background: A revised consensus guideline on therapeutic drug monitoring (TDM) of vancomycin for serious methicillin-resistant Staphylococcus aureus (MRSA) infections was recently published with endorsement of numerous American pharmacy and medical societies. Changing practice from trough TDM to area-under-the-curve-(AUC)-guided dosing was suggested. Methods: Recent literature was critically appraised to determine whether AUC TDM is appropriate for Canadian hospital practice. Results: Previous 2009 vancomycin consensus guidelines recommended trough levels of 15–20 mg/L for serious MRSA infections, based on relatively poor evidence for efficacy or safety. In the past decade, aggressive trough targets have led to unnecessary toxicity. Adoption of a TDM strategy using an alternative parameter (AUC) has been suggested, although the evidence for any outcome benefits is low quality. In addition, implementation would require greater resources at health care institutions in the forms of more frequent serum levels or acquisition of costly Bayesian software programs. Most studies on this subject have been observational and retrospective; therefore, relationships between TDM parameters and outcomes have not been convincingly and consistently demonstrated to be causal in nature. Despite claims to the contrary, based on few in silico experiments, available clinical data suggest correlation of trough levels and AUC is high. TDM with lower target trough levels is a simpler solution to reduce risk of toxicity. Conclusions: There are serious concerns with adoption of AUC TDM of vancomycin into routine practice in Canada. Trough-based monitoring with modest reduction in target levels remains the most evidence-informed practice at this time.

Published: March 2021

Purpose: The authors examine whether community-dwelling older adults at high fall risk have lower backward walking speed reserve (WSR) than their healthy counterparts. Method: Twenty-one healthy older adults and 20 older adults at high fall risk performed five trials of forward walking at a self-selected and maximal pace. In addition, all participants walked backward at a self-selected pace, and 15 participants from each group walked backward at a maximal pace. WSR was calculated as the difference between maximal and self-selected walking speed. Comparisons between groups were made using a one-tailed independent samples t-test or Mann–Whitney U-test with an α value of 0.025. Results: Older adults at high fall risk were significantly slower during self-selected forward walking (11.7%; p = 0.006), maximal forward walking (15.5%; p = 0.001), self-selected backward walking (25.3%; p = 0.002), and maximal backward walking (23.8%; p = 0.006). Older adults at high fall risk showed a lesser forward WSR (25.4%; p = 0.03) and backward WSR (23.7%; p = 0.03). Conclusions: Backward WSR is not useful for discriminating between healthy older adults and older adults at high fall risk. The results imply that forward or backward walking speed rather than WSR might be a useful measure.

Authors: Ahmed Waleed Saadi , Tajer Salah M. , Sayaly Hend M. 
Published: March 2021

Background: Acute appendicitis is the commonest non traumatic cause of acute abdominal pain that needs surgical management .Alvarado score and ultrasonographies are the most cost effective, easy and available aids for diagnosis. The aim of the study was determining the reliability of Alvarado score and ultrasound in the diagnosis of acute appendicitis.
Results: The study was applied with 100 cases with different types of abdominal pain at presentation with 51 males and 49 females .The sensitivity was97.3% ,specificity 90%, and accuracy 89 of combined usage of Alvarado score and U/S findings preoperatively.
Patients and method: A prospective non-interventional study including patients admitted with suggestive history with signs and symptoms of acute appendicitis to the surgical emergency ward of Baghdad teaching hospital from July 1st 2017 to Feb 10th 2018, Alvarado score calculated and ultrasonography done for each patient enrolled in this study, then to be followed for intraoperative findings.
Conclusions: Combined application of Alvarado score and U/S has sensitivity 94.1% ,specificity 90% and accuracy 89% . In our medical facility and emergency ward, acute appendicitis remains as one of the top acute abdominal emergencies needing surgery in patients presenting with atypical clinical ﬁnding. So diagnosis becomes difﬁcult. So Alvarado score along with ultrasound findings are useful for increasing the reliability in emergency department for accurate diagnosis of acute appendicitis therefore there should be training for the use of U/S by emergency physician and general surgeon in the diagnosis of acute appendicitis in order to decrease the rate of negative appendectomies .

Published: March 2021

Background Mitral valve (MV) is one of the most complex structures in human heart with a challenging exposure. Traditionally, MV is approached via left atriotomy (LAA) while superior septal approach (SSA) is an alternative.Objective: is to highlight the merits and demerits of these two approaches in providing access to the MV in term of the aortic cross clamp time (ACCT), quality of exposure, and potential complications in view of the published literature.
Patients and Method: Over an 18-month period ending at June 30th, 2019, 56 patients with MV disease ± other cardiac diseases were enrolled in this study. Twenty patients had surgery via LAA (one surgeon) whereas 36 were operated upon via SSA (another surgeon). Standard surgery was done via median sternotomy, cardiopulmonary bypass and hypothermia of 32 0C. Perioperative events were recorded.
Results In SSA group (males=25; age ranged 23-74 years; mean=57.4), patients had chest pain and breathlessness for a mean of 3 months (>LAA) besides low ejection fraction (EF) in 44%, atrial fibrillation (AF) in 38.9% and dilated LA in 19.4%. They underwent 25 MV replacements (MVR), 11 MV repairs (0 in LAA), 11 coronary artery bypass grafts (CABGs) (2.6 graft per patient vs. 1.3 in LAA; significant) and 2 aortic valve replacement. Mean ACCT was 81.6 minutes (˂LAA). Postoperatively, 32 patients (88.9%) had a normal or improved EF, 11 of 14 AF patients (78.6%) reverted to sinus rhythm and no hospital death was recorded. Conclusion Besides excellent exposure, the SSA enabled us to perform MVR or repair ± additional interventions within a short time and without a heart block. Hence, our results matched the international literature.

Authors:   MIREA – Russian Technological University, Rybakova Marina V. 
Published: March 2021

The modern era of digital economy lays new claims to the system of education and professional learning. Digitation of higher education reveals new prospects for using digital resources to ensure accessibility, continuity and quality of education. The purpose of our investigation is to assess the effectiveness of the use of digital educational resources by students studying foreign languages. Principal methods of our research are as follows: bibliographic method of studying regulatory documents and scientific and methodological literature; the analysis of foreign language competences, mastering of which is the aim of foreign language teaching in a University; the study and generalization of working experience using digital technologies in foreign language teaching; experiment involving 24 students from MIREA – Russian Technological University. As a result of the study frequency of thematic terms and notions use in scientific-teaching literature and Internet search requests was defined; the analysis of modern digital educational technologies forming students’ foreign language competences was made; foreign language competences analyzed in the experiment were described; an experiment involving the comparison of application efficiency in using traditional and digital techniques for forming foreign language competences was carried out. The experiment showed the following: absence of statistically important differences in the level of formed foreign language competences in control and experimental groups at the beginning of the experiment as t = -0.99, p = 0.43. At the end of the experiment p < 0,05: t = -5.19, p = 0,000014. It testifies that the compared groups significantly differ that proves the effect of web-quest technique in teaching foreign languages. Digital educational resources contribute to mastering a foreign language as a means of professional communication and increase the motivation of students to study this subject. Prospects for further research can be related to the development of new forms and methods of applying innovative digital technologies with the aim to put them into foreign language teaching practice at the higher education level.

Published: March 2021

Objetivo: Determinar las características clínicas y epidemiológicas de los traumatismos deportivos oculares de la población asistencial de un hospital terciario de Madrid.
Método: Recopilación retrospectiva de los datos clínicos de los pacientes que acudieron al servicio de urgencias del Hospital Clínico San Carlos en el periodo enero 2015-diciembre 2017 y que habían sufrido un traumatismo ocular durante la práctica de algún deporte.
Resultados: Se incluyeron en el estudio un total de 54 pacientes. 47 (87.04%) fueron hombres. La edad media fue de 27.26 años ± 13.01 años de desviación estándar. El deporte que causó más traumatismos entre los pacientes incluidos en el estudio fue el fútbol, seguido de deportes de raqueta, fuerza y combate y baloncesto. La iritis traumática fue el diagnóstico más frecuente, seguido de lesión periocular, lesiones de polo anterior, conmoción retiniana, lesiones regmatógenas, fractura orbitaria y desprendimiento de retina. El 87.04% de los cuadros se resolvieron con tratamiento médico.
Conclusiones: La mayoría de los traumatismos oculares deportivos son leves y se resuelven apenas con tratamiento médico. Se deben excluir diagnósticos más graves que requieran de un tratamiento más específico. Las campañas de prevención de daños deben ir encaminadas a los grupos con mayor riesgo de presentarlos.
