Published: April 2020

The performance analyses of 15 kWp (kW peak) Grid -Tied solar PV system (that considered first of its type) implemented at the Training and Energy Research Center Subsidiary of Iraqi Ministry of Electricity in Baghdad city has been achieved. The system consists of 72 modules arranged in 6 strings were each string contains 12 modules connected in series to increase the voltage output while these strings connected in parallel to increase the current output. According to the observed duration, the reference daily yields, array daily yields and final daily yields of this system were (5.9, 4.56, 4.4) kWh/kWp/day respectively. The energy yield was 1585 kWh/kWp/year while the annual total solar irradiation received by solar array system was 1986.4kWh/m2. The average power losses per day of array, system losses and overall losses were (1.38, 0.15, 1.53) kWh/kWp/day respectively. The average capacity factor and performance ratio per year were 18.4% and 75.5% respectively. These results highlighted the performance analyses of this PV solar system located in Baghdad city. The performance can be considered as good and significant comparing with other world PV solar stations.

Authors: Shibeeb Mazin , Alwasiti Asawer , Al_Zubaidi Nada
Published: April 2020

Experimental tests were carried to control lost circulation in the Khabaz oil field using different types of LCMs including Nano-materials. A closed-loop circulation system was built to simulate the process of lost circulation into formations. Two dolomite plugs were used from different depths of the formation of Azkand in Khabaz oil field. The experimentations were carried out to study the effect of different types of LCMs, cross-linked copolymer (FLOSORB CE 300 S), SiO2 NP, and Fe2O3 NP, on mud volume losses as a function of time.

The rheological measurements of the nanoparticles-reference mud system showed that both of the SiO2 NP and Fe2O3 NP worked best at 1.2 g/l. and the closed-loop circulation system showed that SiO2 NP cured losses by 48.3% and 37.5% for core plugs 5C1 and 1C2 respectively which is better than Fe2O3 NP loss curing which was 37.9% and 31.3% for core plugs 5C1 and 1C2 respectively.

On the other hand, FLOSORB CE 300 S- Fe2O3 NP-reference mud systems cured losses up to 69% with 0.25g/l FLOSORB CE 300 S and 79.3% with 0.5 g/l FLOSORB CE 300 S which is better than the FLOSORB CE 300 S- SiO2 NP-reference mud systems results.

Published: April 2020

The reduction in the rivers capacity is one the most important issue to give the decision maker an idea during the flood season. The study area included the rivers of the Al Atshan, Al Sabeel and Euphrates, which are surveyed with a length of 21, 5 and 20 km respectively. The Euphrates , the Atshan and Al Sabeel rivers were simulated by using HEC-RAS 5.0.3 software to study the real condition within the city of Assamawa. As well as the simulation was implemented by modifying the cross sections of the Euphrates and Al Sabeel rivers to increase their capacity to 1300 and 1200 m3/s respectively which are a flood discharges100 year return periods. The results showed that the maximum discharge capacity under real conditions of Euphrates River is 750 m³/s and both Al Atshan and Al Sabeel arms  are 500 m3/s.

Authors: De la Torre María Laura , Kostianovsky Alex , Pisoni Cecilia Nora
Published: April 2020

Introduction: Giant cell arteritis (GCA) is the most frequent systemic vasculitis in patients older than 50 years. The diagnosis is based on the clinical history, laboratory findings and imaging studies associated with a temporal artery biopsy (TAB). However, the biopsy result could be inconclusive in up to 40% of the cases. The aim of this study was to review the current management of the patients with clinical suspect of GCA in the university hospital CEMIC in Buenos Aires, Argentina, and correlate the disease behavior with the TAB result. Methods: Retrospective study that reviewed consecutive patients to whom a TAB was made in an 11-year period (2005-2016). Clinical and pathology reports were reviewed. Descriptive statistics were performed. Quantitative variables were described as mean (S.D.) or median [range or inter- quartile range (IQR)] and qualitative variables as number (%). To compare the characteristics of the groups, bivariate analyzes were performed using contingency tables and logistic regression models if necessary. Results: Sixty three patients were included, 68% women. The mean age was 72 years old (SD 8.4). Seventeen biopsies (26.9%) were positive for GCA. The average post fixation length was 1.68 cm (SD 1.2). Patients were divided into 3 groups taking into account the result of the TAB, the ACR criteria and the imaging studies. We could not identify predictors of biopsy positivity. The group of patients with GCA and negative TAB showed a higher percentage of patients with abnormal temporal artery at physical examination. Conclusion: The TAB positive percentage (26.9%) was similar to the reported in other series as well as the post fixation length.  We could not identify predictors of biopsy positivity.

Con alerta pero sin pánico. El rol de los medios durante la pandemia.
Authors: Segura María Soledad
Published: April 2020

Este artículo analiza la cobertura mediática del avance de la pandemia de Covid-19 en Argentina y la medida de aislamiento social preventivo y obligatorio decretada por el gobierno nacional. Destaca tendencias problemáticas y buenas prácticas según un enfoque teórico-normativo, y las vincula con las características históricas del sistema de medios en el país. Utiliza una perspectiva teórico-metodológica que concibe a la comunicación como un derecho humano fundamental, esencial en una sociedad democrática y a los medios de comunicación de masas como vehículo fundamental para su ejercicio, y se apoya en las recomendaciones formuladas por organismos internacionales, organizaciones de la sociedad civil e instituciones nacionales. Se sostiene que los medios de comunicación de masas en la Argentina tienen la oportunidad histórica de mostrar la relevancia de su aporte no sólo para que enfrentar esta coyuntura, sino también para que salgamos de ella como una sociedad mejor y más justa.

65 patients with nonalcoholic fatty liver disease (NAFLD) were included in open-label observative prospective cohort study. Mean age was 54.8 ± 10.5 y. o. All patients were treated with metformin before and during the study. All patients were treated by GLP-1 receptor agonist dulaglutide subcutaneously weekly 26 weeks. Patients of group with type 2 diabetes were treated with dulaglutide 0.75 mg weekly 2 weeks, than 1.5 weekly 24 weeks. Patients of group without diabetes were treated by dulaglutide 0.75 mg weekly 4 weeks, than 1.5 weekly 22 weeks. Both groups of patients were demonstrated significant reduce of body weight, BMI, waist circumference, glucose, HbA1c, insulin resistance indexes, transaminases and gamma-glutamyltranspeptidase activity. Fatty liver index and liver stiff ness also decreased after treatment. We can conclude that dulaglutide treatment in NAFLD patients decreases body wieight, improves glucose and lipid metabolism and decreases inflammatory activity of steatohepatitis.

Authors: Ismailov B. A. , Sadykov R. A. , Kim O. V.
Published: April 2020

Aim of research: to study the comparative effectiveness of new polycompositive of hemostatic implant on in vivo model of liver parenchymal bleeding.

Material and methods. Experimental studies were performed using the developed polycompositive hemostatic implant (CPM) from cellulose derivatives. Main components of implant include: natrium carboxymethylcellulose, oxidized cellulose, nanocellulose and bonded calcium ions. In vivo experiments were conducted in both sexes white 24 utbred rats weighing 196.5 ± 2.8 grams. The animals were divided into two groups: the comparative group (n = 24) with an application of polycomposite hemostatic implant and main group (n = 24) with medical gauze. The hemostatic materials were used in equal weight 30 mg. All surgical procedures on animals were performed under general inhalation anesthesia in model of liver parenchymal bleeding.

Results. Thus, hemostasis was reached within 34.0 ± 2.5 seconds in the main group with CPM, in the comparative group with medical gauze — 142.2±7.7 seconds. Repeated bleeding was observed in 11 (45.8%) cases of the comparative group and in the main group — 2 (8.3%) cases. Biodegradation of the hemostatic implant and regenerative processes in the liver parenchyma were registered on the 14 day, especially in the injured area that indicates the restoration of liver tissue. In the comparative group on the 30th day, the preservation of medical gauze structure was revealed without degradation signs.

Findings. According to our research data, a polycompositive hemostatic implant adheres tightly to the liver tissue, stops bleeding without its recurrence. In histological studies conducted in the dynamics of wound healing of the liver it was found that the implant does not cause a severe inflammatory reaction and biodegradation occurs after 14 days.

Published: April 2020

A 31-year-old man admitted to clinic with complains of occasional pains in the right upper quadrant unrelated to the food. Results of laboratory tests were in the normal range. There were wall thickening of the ascending colon with sites of calcification located intramural according to abdominal contrast-enhanced multislice computed tomography. The above-mentioned structures accumulated contrast during a venous phase of computed tomography. A barium X-ray was performed, filling defects in right colon were detected but barium follow throughs was normal. Multiple dilated vascular structures of variable sizes l affecting the bowel submucosa in ascending colon for more than 10 cm were detected during the colonoscopy. The patient was diagnosed with hemangiomatosis of colon. Because of the high risk of massive large-bowel hemorrhage and malignization the laparoscopic right hemicolectomy was performed. Morfologic findings were interpreted as vascular malformation of colon. The patient has been activated fully on 1-st day after surgery, discharged on 5-th day in hospital. Gastrointestinal (GI) vascular malformation is an infrequent disorder of blood vessel formation characterized by existence of tumor-like vascular structures through the entire GI tract. Nowadays there is no single approach to the management of this group of diseases. Surgery is the only radical metod of the treatment of vascular malformation. The laparoscopic approach has substantional advantages in treatment of this infrequent group of diseases.

Authors: Gaus O. V. , Akhmedov V. A. , Korshunov A. S.
Published: April 2020

Crohn’s disease is an immune-mediated disease characterized by non-specific granulomatous transmural inflammation with segmental damage to any part of the gastrointestinal tract with the formation of extraintestinal and systemic complications. Clinical observation of patient I., 23 years old, a student who was sent for consultation to a gastroenterologist in the direction of a dentist, is presented. Active examination of the gastrointestinal tract during the inspection did not show any complaints. He considers himself ill for 6 months, when he first complained of pain in the neck, sore throat, and body temperature rise to 37.4–37.5 °C, mostly in the evening. Were treated by an otolaryngologist and a dentist without significant effect. In this connection, a biopsy of the ulcerative defect of the left retromolar region was performed, revealing noncaseating granulomatous inflammation. A follow-up examination by a gastroenterologist with colonoscopy and biopsy made it possible to establish Crohn’s disease as the true cause of aphthous stomatitis.
KINERJA GURU DALAM MENINGKATKAN PROSES PEMBELAJARAN PADA MIN MESJIDRAYA BAITURRAHMANBANDA ACEH

Published: April 2020

Kinerja guru dalam proses pembelajaran adalah hasil kerja seorang guru, baik secara kualitas maupun kuantitas dalam melaksanakan tugas sesuai dengan tanggung jawab dan wewenangnya berdasarkan standar kinerja yang telah ditetapkan. Tujuan penelitian adalah untuk mengetahui: kemampuan dan ketepatan, kualitas, inisiatif, dan kendala guru dalam meningkatkan proses pembelajaran pada MIN Mesjid Raya Baiturrahman Banda Aceh. Penelitian ini menggunakan pendekatan kualitatif. Teknik pengumpulan data melalui wawancara, observasi, dan dokumentasi. Subjek dalam penelitian ini adalah Kepala Sekolah, Guru, dan Siswa. Hasil penelitian menunjukkan bahwa: 1) Kemampuan guru-guru dalam membuat RPP di sekolah sudah ada, sebagaimana terlihat saat melakukan proses pembelajaran guru merasa tidak bingung dan kesulitan lagi, karena semua bahan ajar sudah disiapkan, sesuai dengan kompetensi yang dirumuskan secara jelas dan konkrit. Namun demikian, proses pembelajaran belum sepenuhnya sukses, karena masih ada sebahagian guru yang belum tepat menggunakan RPP pada saat proses pembelajaran berlangsung; (2) Kualitas dan inisiatif guru dalam proses pembelajaran terlihat masih masih belum baik, seperti Rencana Pelaksanaa Pembelajaran (RPP) yang dibuat oleh guru belum semuanya berkualitas, kemudian guru kurang memiliki keterampilan bertanya dengan pertanyaan terbuka terhadap siswa, dimana pertanyaan yang sering diberikan guru adalah pertanyaan tertutup, karena kurangnya menguasai bahan ajar yang lebih luas. Kondisi ini membuat sebahagian siswa kurang dapat mengembangkan daya pikir, imajinasi dan analisis yang tinggi dalam belajar, sehingga dilihat dari peningkatan prestasi belajar siswa belum mengalami peningkatan yang signifikan, karena guru hanya mempersiapkan semua tuntutan proses pembelajaran; dan (3) Kendala yang ditemui kepala sekolah dalam meningkatkan kinerja guru antara lain: kurang tersedianya dana untuk pelatihan guru di luar jam dinas, masih ada sebagian kecil guru kurang aktif dan hasil penataran belum mampu mengimbas kepada temannya, guru juga masih kurang dalam penguasaan landasan kependidikan, sehingga hal ini berdampak terhadap peningkatan kinerja dalam melaksanakan pembelajaran.

Communication on COVID-19 to community – measures to prevent a second wave of epidemic
Authors: Bikbov Boris , Bikbov Alexander
Published: April 2020

The manuscript highlights available data on gap in public awareness about recent clinical and scientific facts about COVID-19, insufficient community knowledge about symptoms and preventive measures during COVID-19 and previous MERS-CoV epidemic, and lack of monitoring the community perception and adherence to preventive measures. We also summarize literature evidence about reluctance to change social behavior and disregard recommendations for social distancing among persons who percept to having low risk of infection or complications, and briefly describe destructive psychological response and misleading communications.Our analysis could be translated into important policy changes in two directions:(1)to communicate recent scientific discoveries about COVID-19 pathophysiology to better prepare public opinion to longer period of extraordinary measures;(2)to implement sociological feedback on knowledge, attitudes and practices among general public and some vulnerable social groups.
GABAergic modulation of performance in response inhibition and interference control tasks
Authors: Faßbender Kaja , Bey Katharina , Lippold Julia V. , hurlemann rene , Ettinger Ulrich
Published: April 2020

Background: Inhibitory control is a crucial executive function with high relevance to mental and physical wellbeing. However, there are still unanswered questions regarding its neural mechanisms, including the role of the major inhibitory neurotransmitter, γ-aminobutyric acid (GABA). Aims: This study examined the effects of lorazepam (0.5 mg and 1 mg), a positive allosteric modulator at the GABAA receptor, on response inhibition and interference control. We also explored the heterogeneity of inhibitory control and calculated delta plots to explore whether lorazepam affects the gradual build-up of inhibition and activation over time. Method: A sample of N=50 healthy participants performed antisaccade, Eriksen flanker and Simon tasks in a within-subjects, placebo-controlled, double-blind randomised design. Results: Lorazepam increased mean reaction times (MRT) and error rates dose-dependently in all tasks (p≤.005). In the antisaccade and Simon tasks, lorazepam increased congruency effects for error rate (p≤.029) but not for MRT (p≥.587). In the Eriksen flanker task, both congruency effects were increased by the drug (p≤.031). Delta plots did not reflect any drug-induced changes in inhibition and activation over time. Delta plots for MRT in the Simon task were negative-going, as expected, whereas those for the antisaccade and flanker tasks were positive-going. Conclusions: This study provides clear evidence for GABAergic involvement in inhibitory control. Furthermore, our findings highlight the diversity of inhibitory control while also pointing out similarities between different inhibitory control tasks. In contrast to MRTs and error rates, the cognitive processes provided by delta plots appear not to be sensitive to GABAergic modulation.Draft version, 02.04.2020.

Media Entertainment as a Self-Regulatory Resource: The Recovery and Resilience in Entertaining Media Use (R²EM) Model
Authors: Reinecke Leonard , Rieger Diana
Published: April 2020

In recent years, the perspective of media use and its contribution to positive outcomes for its users has been expanded towards the media’s potential to facilitate recovery from stress and strain and to support the replenishment of physical and psychological resources. The accumulation of empirical findings in this area calls for a systematization and theoretical integration. The present chapter therefore reviews latest developments in recovery theory and systematically summarizes previous research on the effects of recreational media use. It then proceeds in presenting a new model, the Recovery and Resilience in Entertaining Media use Model (R²EM-Model), linking entertainment use to the short-term experience of recovery and to the contribution to long-term development of resilience-enhancing factors. The chapter concludes with a discussion of open questions and future challenges in this field of research.
Lay people are unimpressed by the effect sizes typically reported in psychological science
Authors: McPhetres Jonathon , Pennycook Gordon
Published: April 2020

It is recommended that researchers report effect sizes along with statistical results to aid in interpreting the magnitude of results. According to recent surveys of published research, psychologists typically find effect sizes ranging from r = .11 to r = .30. While these numbers may be informative for scientists, no research has examined how lay people perceive the range of effect sizes typically reported in psychological research. In two studies, we showed online participants (N = 1,204) graphs depicting a range of effect sizes in different formats. We demonstrate that lay people perceive psychological effects to be small, rather meaningless, and unconvincing. Even the largest effects we examined (corresponding to a Cohen’s d = .90), which are exceedingly uncommon in reality, were considered small-to-moderate in size by lay people. Science communicators and policymakers should consider this obstacle when attempting to communicate the effectiveness of research results.
The One-Dimensionality of Econometric Data: The Frankfurt School and the Critique of Quantification
Authors: Timcke Scott
Published: April 2020

Econometric data are used to produce authoritative facts about the world. Yet, as numbers enjoy a central place in modern reasoning (particularly in government as their presumed objectivity and neutrality assist impartial decision-making), it is important that they receive scrutiny. Using methodological techniques from Western Marxism, with special reference to the work of Lukács, Horkheimer and Adorno, and Marcuse to inform a critique of Acemoglu and Robinson, I argue that the historical emergence of econometrics as a mode of mediated knowledge is a reified practice within the broader technical administration of social life, a practice that is not a transparent representation of social phenomena. This is because when econometrics transforms the thing being measured into a statistical indicator it eclipses political disputes with technical disputes, sidestepping good faith democratic deliberation about what goods are worth pursuing. Effectively, one-dimensional thought cannot perceive the origins of items put into circulation and so ideology is produced – what seems value-free is value-laden.
A Thelypteridaceous Fern from the Early Paleocene Raton Formation, South-central Colorado, and Its Importance in Interpreting the Climate of the Region
Authors: Berry Keith
Published: April 2020

Based on the results of leaf physiognomic studies, it is generally acknowledged that the Raton Basin in south-central Colorado and northeastern New Mexico hosted a tropical rainforest during the early Paleocene. However, this interpretation is problematic because the canopy-forming foliage of this forest was predominately lauraceous, and lauraceous foliage is almost invariably entire-margined. Thus, it may be necessary to look to other, taxonomy-based paleotemperature proxies to test megathermal paleotemperature estimates based solely on leaf physiognomic analyses of predominately lauraceous datasets. In this study, the pantropical fern Cyclosorus sensu lato (s.l.) is reported from the upper coal zone of the Raton Formation. The presence of this fern in the understory of a predominately lauraceous canopy suggests megathermal conditions in the early Paleocene.
Peculiarities of Secondary Education Management
Authors:   Abai Kazakh National Pedagogical University, Kazakhstan, Rakhym M.
Published: April 2020

In the article, the author explored that teenagers differ from adults in that it differs not only in older adults but also in biological development (puberty, etc.). In general, teenagers have different characters. In fact, some teenagers are kind and courteous in dealing with older people during this period, and at times they are more arrogant, that is, more disciplined. This is especially true for students in grades 7, 8 and 9. Teenagers realize that they are no longer children, but are no longer adults. Imitating adults, repeating their behavior, others indulge in harmful habits. Teenagers do not like wisdom. After all, they feel smart. They are against their parents 'warnings, their parents' counsel and their advice and ideas. Teenagers start to grow up, especially when the girls are mature. They pretend to neglect of their short classmates, and as a result, they pay more attention to high school peers. In this regard, the author proposes innovative teaching methods for students in grades 5 through 9.

La séparation liée à l’hospitalisation du nouveau-né et les angoisses sur son état de santé peuvent affecter le comportement de caregiving, système de comportement parental réciproque au système d’attachement chez l’enfant. L’objectif du « cordon numérique » est de soutenir la création du lien en permettant au parent et à la famille d’accéder à des vidéos du nouveau-né, des « morceaux choisis » enregistrés à des moments privilégiés, et de les aider à l’investir psychiquement. Si l’image ne peut remplacer la présence, cet outil contribue à mobiliser le caregiving de parents « empêchés ».
Scale and Number
Authors: Bristley Joseph
Published: April 2020

Much recent anthropology reflects on how scales are contested and contingent products of heterogeneous social interactions, not the ‘ontological givens’ (sensu Carr and Lempert) described in earlier scholarship. This article examines the importance of number in the formation of scales of measurement. It does so regarding a pastoral Mongolian scale of livestock-counting based on the number ten thousand, or tüm[en]: a qualitative-cum-quantitative term suggesting plenty and abundance. Drawing on literature on the anthropology of number, and bringing it into dialogue with studies of scale and ideology, this article argues that number is not just a means for calibrating pre-existing scales. Instead, as something endowed with particular qualities and conceptual stability, number can be mobilized to produce ideologically charged scales of measurement.
The Incitement to Fieldwork
Authors: Keeler Ward
Published: April 2020

Fieldwork necessarily causes some degree of psychological stress for an ethnographer, although the nature and consequences of such stress vary individually. Rather than lament or conceal that fact, I suggest that an ethnographer’s idiosyncratic responses can provide particular insights. To illustrate the point, I consider what might have induced me, and perhaps others, to take on the necessarily disorienting role of an ethnographer. I then contrast my experience (as a middle-aged Western anthropologist) of a meditation retreat in Burma with my experience (as a recently divorced bisexual man) of a naked men’s yoga retreat in Texas. These brief vignettes are intended to suggest that my specific personal conflicts alert me to matters of more general anthropological interest.
Introduction
Authors: Beekers Daan
Published: April 2020

This introduction proposes directions for a comparative anthropology of Muslim and Christian religion. While the anthropologies of Islam and Christianity flourish, comparative inquiries across religious boundaries have remained remarkably underdeveloped. As a result, parallels, overlaps, and situated differences between religious groups in today’s pluralist environments are often disregarded. This piece sets out the aim of this special section to develop ethnographic comparison, not of religious traditions as such, but of the ways in which everyday religious lives take shape within a shared social space, whether local or national. Such comparative work has the potential to provide insights and reveal connections that would likely be overlooked in non-comparative accounts, and that invite a critical rethinking of conventional understandings of difference and particularity.
Commitment, Convergence, Alterity
Authors: Beekers Daan
Published: April 2020

This contribution looks comparatively at the everyday pursuit of religious commitment among young, revivalist-oriented Sunni Muslims and Protestant Christians in the Netherlands. In both public debates and academic scholarship, the differences between these groups tend to be stressed, particularly through dichotomies such as migrant/native and minority/majority. This article, by contrast, takes their potential common ground as a starting point by examining the pursuit of religious aspirations under shared conditions of consumer capitalism and cultural pluralism. I argue that my Christian and Muslim interlocutors experienced a noticeably similar dynamic of constraint on and reinvigoration of their faith.

Pneumonia caused by the novel corona virus has derived the whole world into an emergency situation, bringing to mind similar epidemics including H1N5, dengue, SARS-CoV and MERS. Although SARS-CoV-2 didn't result in such a huge number of deaths when compared to, for example, Spanish influenza, it is categorized as having high infectivity rate. The trials to control the spread of the virus are often challenged by the lack of knowledge which means more time is needed to build a view regarding the pathological actions of the virus in order to properly target it. Recent reports declared that SARS-CoV-2 uses ACE-2 as a means to infect cells. This paper aims at addressing briefly the protective roles of ACE-2 in the lungs and the brain based on previous literature review and studies on other viruses that also use ACE-2 as a target for cellular entry. We hypothesized that COVID-19 pathology may be a consequence of viral Mediated down-regulation of ACE-2. In addition, we provided insights on the potential correlation between COVID-19 severity and male gender or smoking.

A study of the chemical composition, the antioxidant capacity and the sensory characteristics of three Bulgarian wines (vintage 2015) from the native cultivars Misket Vrachanski (white), Pamid (red) and Gamza (red), grown in the region of Pleven, Central Northern Bulgaria was carried out. The results showed that the wine composition was mainly determined by the cultivar and its peculiarities. Misket Vrachanski white wine had the lowest rate of sugar-free extract, glycerol, total phenolic
compounds and the highest acid content. From the red wine samples, Pamid had lower rates for the above parameters compared to Gamza. The experimental wines were analyzed for total content of esters, aldehydes and higher alcohols. A correlation was found between the rates of the studied volatile components in the wines and their aromatic sensory characteristics. At the wine tasting, Misket Vrachanski that contained the most of esters and aldehydes, was the best evaluated, followed by Gamza and Pamid. There was no correlation between the amount of total phenolic compounds in the experimental samples and their antioxidant capacity, which according to ABTS and MRAP methods increased in the order of Pamid < Misket Vrachanski < Gamza.

Convenient caffeine sources include energy drinks that are increasing in
popularity among recreational and professional athletes, military personnel, young adults, and other consumers seeking ‘’energy boosters’’. Since energy drinks are a relatively concentrated source of caffeine, there is a risk of missing individually targeted caffeine intake or risk of inadvertently high intake with adverse effects. Therefore, the accuracy of declared caffeine content of energy drinks is
highly important, especially from a consumer point. The purpose of this
study was to determine caffeine content of 15 beverages available on the Croatian market and compare the analytical with the declared value. Caffeine was determined by high performance liquid chromatography technique with photodiode-array detection (HPLC-PDA). In 5 of total 15 products, a higher caffeine content was determined in average of 3.01 % than the one declared, resulting with increased intake of 4.75 mg caffeine/serving. In another 10 analysed products the content of caffeine was lower in average of 5.33 % (4.79 mg caffeine/serving) in compare to the one declared. Therefore, only with accurate information about the caffeine content in energy drinks may consumers and clinicians
be assured of safe usage.

The aim of this work was to determine the effect of fat and protein oxidation on the colour and texture of Biceps femoris (BF) and Semimembranosus (SM) muscles of smoked dry-cured ham Dalmatinski pršut. Fat and protein oxidation was determined by spectrophotometer methods of
which fat oxidation by 2-thiobarbituric acid reactive substances method
(TBARS) and protein oxidation by 2,4-dinitrophenylhydrazine (DNPH) method. Colour parameters (L*a*b* values) and texture profile analysis (TPA test) were also analysed. There was no statistical significant difference (P>0.05) between BF and SM in fat and protein oxidation. SM is an external muscle and is more exposed to oxygen than internal muscle BF. As a result of that SM showed slightly higher TBARS values than BF. Slightly higher values of carbonyls in BF can be explained by the higher water content in this internal muscle and thus by the stronger proteolytic activity. BF had higher L*, a* and b* values than SM. Higher values of adhesive force, cohesiveness and stringiness and lower values of hardness, adhesiveness, gumminess, chewiness and fracture were found for BF than for SM.

Custard is a convenient food product, similar to ogi in appearance and viscosity, but lacks the sour taste typical of ogi. In this study, extracts (10% w/w) from tamarind, soursop and lime was added to custard samples and the physicochemical and sensory properties of the mixture was analysed. Corn gruel was included as the reference sample. Carbohydrate was the major component of the corn gruel (61.72%) and custard samples (66.27-74.42%). Corn gruel had substantially higher protein content (18.03%) than custard samples (8.03-8.62%). Custard samples were more dispersible in water, showed higher swelling power and
significantly higher peak and final viscosities than the corn flour sample. However, the addition of souring agent did not significantly alter the cooking time and pasting temperature of custard. Custard may be soured with lime, tamarind and soursop to improve dispersibility, consistency, appearance, viscosity and sourness without significant changes in the overall acceptability of the product.
Making Modern Childhood, the Natural Way: Psychology, Mental Hygiene, and Progressive Education at Ontario Summer Camps, 1920-1955
Authors: Wall Sharon Yvonne
Published: April 2020

In the first half of the twentieth century, summer camps in Ontario were promoted as a much-needed escape from city living and the pathway to a world of natural, pre-modern simplicity. This paper demonstrates that, by the late 1920s, camp administrators and promoters were, in fact, pulled in two directions; they treasured the idea of antimodern escape, but, they also sought to make the camp programming “truly modern” by integrating the latest psychological and educational wisdom. At all sorts of camps, the language and aims of educational psychology and the mental hygiene movement influenced the nature of camp goals, camp programming, and thinking about campers themselves. Camp was regarded as providing the ideal environment for fostering psychological health and for applying the principles of progressive education. This paper explores administrators’ view of the value of psychological and educational expertise, the extent to which they were able to apply these at camp, and, to a lesser extent, children’s reactions to the modern, psychologized camp.
Early Struggles for Bilingual Schools and the French Language in the Windsor Border Region, 1851–1910
Authors: Cécillon Jack D.
Published: April 2020

In 1910, Bishop Michael Fallon of London called for the abolition of the bilingual schools of Ontario because of their inefficiencies. Concerns about the value of a bilingual education and the French language in particular predate Fallon and go back to the 1850s in the Windsor border region. These concerns were voiced by both francophones and Anglophones, and illustrate that the struggle for the survival of the French language in the churches and schools of the area predated the arrival of Fallon and the Ontario government’s imposition of Regulation XVII.
Les collèges classiques : nouveaux regards sur une vieille institution
Authors: Baillargeon Denyse
Published: April 2020

Les collèges classiques représentent une institution quasi mythique au Québec. Disparus depuis les années 1960 dans la foulée des changements que connaît alors la province, ils continuent néanmoins de vivre dans l’imaginaire collectif comme des lieux qui ont vu défiler la fine fleur de la société québécoise. Décriée ou encensée, l’image des collèges classiques semble irrémédiablement et exclusivement associée à l’élite canadienne-française qui allait y chercher une vaste culture humaniste en plus d’un passeport pour l’université.

Stock market is an important capital mobilization channel for economy. However, the market has potential loss due to fluctuations of stock prices to reflect uncertain events such as political news, supply and demand of daily trading volume. There are many approaches to reduce risk such as portfolio construction and optimization, hedging strategies. Hence, it is critical to leverage time series prediction techniques to achieve higher performance in stock market. Recently, Vietnam stock markets have gained more and more attention as their performance and capitalization improvement. In this work, we use market data from Vietnam’s two stock market to develop an incorporated model that combines Sequence to Sequence with Long-Short Term Memory model of deep learning and structural models time series. We choose 21 most traded stocks with over 500 trading days from VN-Index of Ho Chi Minh Stock Exchange and HNX-Index of Hanoi Stock Exchange (Vietnam) to perform the proposed model and compare their performance with pure structural models and Sequence to Sequence. For back testing, we use our model to decide long or short position to trade VN30F1M (VN30 Index Futures contract settle within one month) that are traded on HNX exchange. Results suggest that the Sequence to Sequence with LSTM model of deep learning and structural models time series achieve higher performance with lower prediction errors in terms of mean absolute error than existing models for stock price prediction and positive profit for derivative trading. This work significantly contribute to literature of time series prediction as our approach can relax heavy assumptions of existing methodologies such as Auto-regressive–moving-average model, Generalized Auto-regressive Conditional Heteroskedasticity. In practical, investors from Vietnam stock market can use the proposed model to develop trading strategies.

Layered oxides are promising electrode materials for sodium-ion batteries, the next generation of rechargeable batteries. The layered oxides with the tránition metallic manganese and iron have paid more attention due to its low-cost, eco-friendly, and facile preparation. In this work, the metallic sodium oxides with a layered structure based on Fe and Mn, NaFexMn1-xO2 (x = 1/3, 1/2 và 2/3) were synthesized via a solid-state reaction at 900 oC for 12–36 hours. All XRD patterns of NaFexMn1-xO2 pointed out the layered structure. In two ratio Fe:Mn = 1/3:2/3 and 1/2:1/2, the synthesized samples presented the P3-layered structure, while in ratio Fe:Mn = 2/3:1/3, the O3-structure was obtained. The lattice parameters were determined by Celref software. The lattice parameters and the volumic of unit cells depended on the ionic radius of cation Mn3+ and Fe3+. The Na-migration was studied by the cycling test with a constant current. The charge-discharge curves and the specific capacity depended on the ratio of Fe:Mn. The specific capacity was found out 120 mAh/g (1/2:1/2), 118 mAh/g (2/3:1/3), and 120 mAh/g (1/3:2/3). After 20 cycles, the capacity was maintained 77 mAh/g (1/2:1/2), 88 mAh/g (2/3:1/3), and 80 mAh/g (1/3:2/3).
