Published: September 2021

The aim: To research the effectiveness of cryopreserved blood plasma replacement therapy in patients with primary mannose binding lectin (MBL) deficiency, suffering from chronic active herpes virus infections.
Materials and methods: Patients of the study group (SG) n= 36 additionally received cryopreserved blood plasma therapy Octaplas (Octapharma, Switzerland). Patients of the control group (CG) n=36 received only chemotherapy with Valganciclovir 450 mg 2/day per os for 1-3 months. The diagnosis of active herpes virus infection was established by PCR of blood leukocytes. Statistical analysis of the obtained information was processed by the calculation of the chi-square (χ2) Pearson criterion, the odds ratio and the associated 95% confidence interval (95% CI).
Results: The adding cryopreserved blood plasma substitute to standard therapy with valganciclovir for the treatment of chronic active herpes virus infection in patients with total serum MBL deficiency below 50 ng/ml, allowed to get more negative PCR results.
The effectiveness of combination therapy was 50% higher in carrier of HHV-6 (χ2=8,533 and р=0,004; Yeats correction 6,533 and significance 0,011; OR=11,667 and 95% CI=1,939-70,180) and 43% in carrier of HHV-7 (χ2=8,846 and р=0,003; Yeats correction 7,165 and significance 0,008; OR=6,375 and 95% CI=1,711-23,758), compared with monotherapy. The close association between deficit MBL compensation and the results of antiviral treatment is also reported. The effect of such treatment in patients with chronic EBV infection was less (27%).
Conclusions: We assumed, that virostatic effect of valganciclovir is increased by MBL-mediated clearance of blood serum from viral particles.

Published: September 2021

The aim: Is to define dentine chemical composition of intact teeth and those with wedge-shaped defects followed by the analysis of revealed differences.
Materials and methods: Longitudinal sections of 22 clinically removed teeth (12 – clinically intact ones, 10 – with wedge-shaped defects) from both jaws were studied in patients aged between 25-54 years. JSM-6490 LV focused beam electron microscope (scanning) with system of energy-dispersive X-ray microanalysis INCA Penta FETх3 was used. The chemical composition of 148 dentine areas in the incisal region (tubercle), equator, cervical area has been determined as a percentage of the weight amounts of carbon, oxygen, calcium, phosphorus, sodium, magnesium, sulfur, chlorine, zinc, potassium, aluminum.
Results: Dentine chemical composition of teeth with wedge-shaped defects differed from those of intact teeth by significantly lower content: sodium, chlorine and calcium – in the incisal region (tubercle); sodium, magnesium − at the equator; sodium, chlorine and calcium – in the cervical region (p≤0.05). In the sample groups with cervical pathology there was more sulfur and oxygen in the incisal region (tubercle), phosphorus and zinc – at the equator, carbon and potassium – in the cervical region (p≤0.05).
Conclusions: Differences in the chemical composition of intact teeth and teeth with wedge-shaped defects, the presence of correlation between the studied chemical elements confirm the role of macro- and microelements in the pathogenesis of non-carious cervical lesions.

Authors: Konoplitskyi Viktor S. , Korobko Yurii Ye.
Published: September 2021

The aim: The study of pathomorphological changes in uterine appendages during torsion of different duration and after their detorsion in the experiment on rats.
Materials and methods: Experimental studies were performed on the basis of vivarium in the conditions of chronic experiment on 48 females of outbred white rats weighing 200.0 ± 20.0 grams.The essence of the experimental model is that the female rats, under the ketamine’s anesthesia at the rate of 1-2 mg / kg of the drug, conduct a right-sided ovary twist at 7200 in the projection of the oviduct with fixation of the organs with an external clip of indifferent metal.
Results: After ovarian detorsion, until 72 hours after its torsion, reliable reversible restoration of the structural components of the ovary is determined as a positive consequence of the effect of the correction factor (detorsion).
Conclusions: The data obtained in the experiment showed that there was a discrepancy between the macroscopic features of the twisted uterine appendages and the microscopic changes in their morphological examination. Despite the presence of external signs of necrosis in the tissue of the uterine appendages, after the detorsion and the restoration of blood flow in them, studies have shown the possibility of performing organ-saving surgical operations in the torsion of the uterine appendages.

The aim: To conduct a comparative analysis of clinical data, laboratory results, and pain intensity in patients using developed by us device for offloading the foot and plaster splint during inpatient treatment of purulent-necrotic complications of diabetic foot syndrome.
Materials and methods: We examined 76 patients with purulent-necrotic complications of diabetic foot syndrome, who used a plaster splint and a device for offloading the foot. We evaluated the clinical indicators of the healing process, laboratory data and pain intensity.
Results: Comparing the results of using the device for offloading the foot and the plaster splint showed that the developed by us device had a positive effect on the dynamics of the healing process: the edema disappeared on average 1.5 days earlier; the redness vanished on average 2.5 days earlier. We observed granulation and epithelialization significantly earlier (p <0.05) than in the group where the plaster splint was used. The number of recorded surgical interventions was statistically significant and less (p <0.05) in the group where our device was used. Low pain rates were in patients using a device for offloading the foot due to minimal contact of the wound surface with the floor.
Conclusions: According to the results of comparative using the device for offloading the foot and plaster splint, we found out that using the device for offloading the foot allows creating statistically significant better conditions to accelerate wound healing in patients and reduce the duration of inpatient treatment.

The aim: To obtain the estimates of the current prevalence of healthcare-associated infection among neurosurgical patients and determine the antimicrobial resistance of responsible pathogens in Ukraine.
Materials and methods: We performed a retrospective multicenter cohort study was based on surveillance data of HAIs among neurosurgical patients from 2017 to 2019 in 7 regional hospitals. Definitions of HAI were used from the CDC/ NHSN.
Results: Of 9,711 neurosurgical patients, 1,031 (20.9%) HAIs were observed. The most frequently of HAI types were surgical site infection (53.2%), pneumonia (17.3%), urinary tract infection (15.1%) and bloodstream infection (14.4%). The overall prevalence of HAIs was 20.9% within three months and was 12.8% during one month surveillance period. Death during hospitalization was reported in 11.3% of HAI cases. Escherichia coli were most commonly reported, accounting for 24.3% of all organisms, followed by Staphylococcus aureus (15.9%), Enterococcus spp (14.6%), Pseudomonas aeruginosa (13.4%), and Klebsiella pneumoniae (9.8%). Meticillin resistance was 34.6% of S.aureus isolates. Vancomycin resistance was in 7.1% of isolated enterococci. Among the gram-negative bacteria, third-generation cephalosporins resistance was found in 48.5% of K.pneumoniae and in 34.3% of E. coli isolates. Carbapenem resistance was reported in 11.7% of all included Enterobacteriaceae, also highest in K.pneumoniae, and in 32.4% of P.aeruginosa isolates and in 67.2% of Acinetobacter spp. isolates.
Conclusions: Healthcare-associated infections are a cause for mortality and morbidity among hospitalized neurosurgical patients. This is due to increase emergence of antimicrobial-resistant pathogens. Routinely collected surveillance data are of great value as a basis for studying the consequences of HAIs.

Authors: Lymar Lesya , Storozhuk Khrystyna
Published: September 2021

The aim: To define peculiarities of the medical students and medical PhD students’ distance learning, basing on the academic performance and survey results.
Materials and methods: Forty-two medical students and thirty-eight PhD students of O.Bogomolets National medical university were randomly chosen for the study. Students’ knowledge of English was initially “ live” assessed in February, online assessments were held in April and May, concluded with the credit final assessment. Upon passing the final test the students were asked to fill in the questionnaire containing the following items: satisfaction with the distance learning, level of the distance learning hardness, comparison of distance learning by quality and understanding, choosing the best sections for the English distance learning, level of technical problems.
Results: All students during the 2020 distance learning have improved their English language level: the medical students from 3.8 to 3.99, the PhD students- from 4.36 to 4.56. The questioning of both groups showed significant dissatisfaction of medical students ( 52-57% by different positions) with the distance learning. The PhD students showed higher satisfaction level (76-86% by different positions).
Conclusions: The assessed groups of the O.Bogomolets National medical university improved their English knowledge level during the distance learning. The authors relate significant dissatisfaction of medical students with the distance learning to their low motivation and learning maturity. The PhD students’ higher satisfaction level may be related to the wider variability of the issues to study. The problem of distance learning of both medical and PhD students should be studied more thoroughly.

Published: September 2021

Amniotic fluid embolism (AFE) is a diagnostically challenging type of pulmonary embolism that occurs when amniotic fluid enters maternal circulation during delivery or postpartum. This obstetric complication is very rare but characterized by high mortality rate. The main symptoms are dyspnea, cardiovascular collapse, disseminated intravascular coagulation (DIC) and even sudden cardiac death.
The aim of the article is to draw attention to AFE as a rare but possible and catastrophic complication of perinatal period. The authors present a 28-year-old woman who was admitted to obstetric ward during the first stage of labour. The patient developed sudden deterioration of her medical state with acute respiratory distress symptoms. An emergency cesarean section was performed, complicated by excessive bleeding. After a detailed assessment of the patient’s condition and evaluation of the results of additional tests, we diagnosed AFE as the cause of the patient’s deterioration.
Conclusions: The case study shows how unpredictable, unpreventable and dangerous is AFE. It is still one of the main causes of maternal deaths in developed countries. Four diagnostic criteria proposed by the Society for Maternal-Fetal Medicine (SMFM) may accelerate diagnosis. AFE as a medical emergency, requires immediate multidisciplinary response and aggressive treatment. The initial medical care may be facilitated by the application of the general guidelines recommended by SMFM. The case report also emphasizes the need for further research on this disease, in particular on early detection and prevention.

The article summarizes the factors that determine the innovative development of regional economic systems. It was determined that the desire to diversify the sectoral structure should be based on an understanding of the role of construction as a sector of the economy, outstripping the development of the general economic situation. The hypothesis about the existence of a strong relationship between the volume of work in construction and the volume of output of innovative products in regional economic systems has been put forward and confirmed. In 2010–2018, there is a close relationship between the number of commercialized innovations and the volume of work in the construction industry in Russia. At the same time, the correlation between these parameters in various federal districts and subjects of the Russian Federation is not unambiguous. Russian regions are classified according to the strength of the relationship between these parameters. It is concluded that, mainly, in the border regions, construction is not associated with the development of innovative industries and innovative infrastructure.

Authors: Rivas Romero Javier A. , Alvarez-Requena Jacob J. , Bravo-Santizo Vinicio
Published: September 2021

La fenología estudia los cambios estacionales en los ciclos de vida de los organismos. Una utilidad de la fenología, es que permite establecer periodos en que se pueden colectar semillas para programas de restauración ecológica. Por lo que, de abril de 2017 a mayo de 2019, en el volcán Tacaná, San Marcos, Guatemala, se estableció la estacionalidad, variación anual, sincronía, intensidad y duración de las fenofases reproductivas de Prunus lundelliana Standl. Aproximadamente cada 15 días, en 10 individuos se registró la presencia e intensidad de las flores (botones y abiertas) y frutos (inmaduros y maduros). Los datos se analizaron con estadística circular, encontrándose que todas la fenofases fueron estacionales y que solo el patrón de los frutos inmaduros varió significativamente entre los dos periodos. La sincronía fue principalmente alta y la intensidad no superó el 40%. En ambos periodos las intensidades menores las presentaron los frutos maduros (17 y 25%). Los índices de actividad e intensidad se correlacionaron significativamente, por lo que los ángulos medios fueron semejantes en las fenofases y periodos de estudio. Los picos de actividad-intensidad de las flores abiertas y de los frutos maduros ocurrieron durante los meses secos (noviembre-abril), patrón que se ha registrado en otros bosques nubosos. La duración de las fenofases varió entre 2.5-3.5 meses, siendo la más pequeña la de frutos maduros. Para fines de manejo, la colecta de frutos maduros puede hacerse desde mediados demarzo hasta finales de mayo, sin embargo, se sugiere hacerlo principalmente entre el 15 de abril y el 15 de mayo.

Image processing becomes one of the most important demands, requisites and exigencies in the 20th century, because of its usages in many and different parts of habitats and customs, so the enhanced image represents the main issue for scientists and researchers, where little methods, devices and programs were existing. According to this, our study was significantly concerned with the image processing; namely, the living cell imaged using different lenses on the confocal microscopy. The microscope was designed very well to give perfect resolution imaged taken from different situation (angles) and different lenses with the magnification (X = 40, 100 and 160) and various light sources (white light, laser red, laser blue, and laser green). From the results conducted and achieved it's clear that the lens with magnification 100 and near wavelength light color gives more information about the living cell (object). The histograms confirm vigorously these results, so this could solve and enhanced the resolution image in multi disciplines, scopes and avenues.

Published: September 2021

Recycling metals waste is one of the ways to recover this waste, but also to preserve mining resources and fight against pollution. Aluminum is one of the most recycled metals due to its relatively low melting temperature, high conductivity, ductility, malleability and its high resistance to corrosion. In Togo, as in many West African countries, aluminum wastes are collected, melted and molded in artisanal way to make new objects for domestic use. The aim of this work is to investigate the process of artisanal aluminum recycling and use several modern techniques of characterization in order to improve thereafter products and manufacturing process. Two types of samples were subjected to a series of physicochemical analysis. One from an old aluminum pot (sample (a)) and the other cut from newly pot obtained after artisanal manufacturing (sample (b)). The measurement of the temperature inside the crucible during scarp aluminum melting operation reveals three temperatures ranges with a melting point around 750℃. Atomic absorption spectrometry (AAS) indicates that the two samples contain mostly aluminum, zinc, copper, magnesium and some traces of lead. Optical microscopy observations show that the alpha aluminum matrix was the most abundant phase with 80 to 90% of the observed area and some inclusions randomly dispersed. X- ray diffraction (XRD) confirms the presence of lines characteristic of alpha aluminum and bohemite (γ-AlOOH).
Matrine Promotes Dendritic Cell Activation and Enhances Anti-tumor Effect of Human Gastric Carcinoma Dendritic Cells Vaccine in Vitro
Authors: Zhou Ning , Zhang Fan , Chen Cong
Published: September 2021

Objective: The purpose of this study was to investigate whether matrine can affect the phenotypes and functional maturation of dendritic cells (DC), and to secrete many cytokines, as well as the cytotoxic T lymophocyte (CTL) specific killing effect induced by gastric carcinoma
dendritic cells vaccine in vitro. Materials and methods: The experimental groups consisted of three concentrations of matrine (0.5, 1.0, and 2.0 mg/mL). The DC maturation was detected by flow cytometry. The proliferation of T cells was detected by cell counting kit-8 (CCK-8) method.
The secretions of cytokines by CTLs were detected by enzyme-linked immunosorbent assay (ELISA). The specific killing capacity of CTLs to target MKN45 gastric cancer cells was detected by lactate dehydrogenase (LDH) release assay. Results: The results showed that matrine could increase
the expressions of CD86 and CD83 in a dose-dependent manner. Matrine could promote T cell proliferation (P<0.05). Moreover, matrine also significantly increased the levels of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α) and interleukin-12p70 (IL-12p70),
respectively (P<0.05). The therapeutic vaccination with DCs vaccine treated with lipopolysaccharide (LPS) plus matrine resulted in improved killing effect as compared to that observed with DCs treated with LPS alone (P<0.05). Conclusion: These findings define matrine
as an immune adjuvant that enhances the DC activation and demonstrate a new pharmacological approach to improve the therapeutic effect of autogenous DC vaccines.

Objective: With the fast development of economy and culture, medical professionals parents are paying more and more attention to nocturnal enuresis (NE) since it rais ed the negative impact on children's health and imposes a long -term burden on families. The present clinical
investigation aims to evaluate the clinical effect of pressing needle on nocturnal enuresis in children through a randomized controlled clinical trial. Materials and Methods: A total of 120 children with nocturnal enuresis were randomly assigned into pressing needle group, desmopressin
group and pills Capsule group, 40 cases in each group. The children in pressing needle group were treated with pressing needles, and those in the desmopressin group and Suoquan pills were orally administrated with desmopressin and Suoquan pills, respectively. Combined behavioral therapy was
also given in all the three groups during the treatment. Enuresis frequency, degree of arousal, functional bladder capacity (FBC) and postvoid residual urine volume (PRUV) were employed as the indicators to evaluate the clinical efficacy in the three groups. After 6 months of follow-up, the
recurrence rate of the three groups was also analyzed for efficacy assessment. Results: The total responsive rate in pressing needle group was 95.0%, which was higher than 87.5% of Suoquan pills group (p < 0.05), and significantly higher than 77.5% of desmopressin group (p < 0.01).
The frequency of enuresis was significantly lowered after treatment (p < 0.01), concurrently with an evident improvement in arousal levels in all of the three groups (p < 0.01), and the inter-group difference in post-treatment enuresis frequency and arousal level between pressing needle
group and the other two groups was also statistically significant (p < 0.05). The recurrence rate of pressing needle group, desmopressin group and Suoquan pills group was 7.89%, 48.39% and 22.86%, respectively, with a difference which was statistically significant between pressing needle
group and desmopressin group (p < 0.01), but not between pressing needle group and Suoquan pills group (p > 0.05). Conclusion: Pressing needle treatment showed a substantial clinical effect on enuresis in children by improving the bladder function, increasing the FBC and reducing
PRUV of the bladder, as well as by enhancing the degree of arousal and lowering the recurrence rate, therefore is suggested to be considered as an option for enuresis treatment for children.

Published: September 2021

Über zwei Jahrzehnte hat sich an der Hochschule Offenburg im Umfeld von Professor Elmar Bollin eine Forschungsgruppe etabliert, die die Bereiche Gebäudeautomation und nachhaltige Energietechnik zusammenführten. Anfänglich ging es darum die Potenziale der internetbasierten Wetterprognostik und modell-basierten Anlagensteuerung für die Verbesserung des Komforts und der Energieeffizienz im Gebäude zu nutzen. Im Rahmen von Forschungs- und Entwicklungsarbeiten mit Einsatz von dynamischen Gebäudesimulationen konnte schließlich ein Algorithmus gefunden werden, der es ermöglichte auf Basis von prognostizierter Außentemperatur und Sonneneinstrahlung den Energiebedarf eines Bürogebäudes für den Folgetag vorherzusagen. In Verbindung mit der Gebäudeautomation entstand so die adaptive und prädiktive TABS-Steuerung AMLR.

Din Eğitimi Öğretmenlerinin Bilgi ve Dini Bilgi Anlayışları
Authors: SAYIN Gülşen , TOSUN Cemal
Published: September 2021

Dini bilgi sahip olunan inançlar ekseninde bireylerin zihin dünyaları ve hayatlarında kuşatıcı bir boyuta sahiptir. Dini bilgi inanan bireyler için yalnızca ibadet boyutu ile varlık göstermez aynı zamanda hayatın bütünü için de yönlendirici olabilmektedir. Günlük yaşantıdaki eylemlerde de dini bilgiye sıklıkla referans yapılmaktadır. Dini bilgi bu yönüyle bireyler için günlük yaşamı düzenleyen ve bunu da sahip olduğu dünya görüşü üzerinden gerçekleştiren bir sisteme sahiptir. Dini bilginin öğretim süreçlerinde ön plana çıkan boyutu, dinin sahip olduğu dünya görüşünü ve bunu ne düzeyde yansıttığını da doğrudan etkilemektedir. Eğitim sistemi içerisinde yer alan din öğretimi her ne kadar öğretim yöntem ve teknikleri ile ele alınan bir eğitim faaliyeti olsa da öğretmenler sahip oldukları dini bilgi anlayışları ile din öğretimi süreçlerini şekillendirebilmektedirler. Denilebilir ki din eğitimi öğretmenlerinin dini bilgi anlayışları din öğretim süreçlerinde nasıl bir din öğretimi yaklaşımı benimsendiğini ve kullanılan öğretim yöntem ve tekniklerini etkilemektedir. Bu anlamda din eğitimi öğretmenlerinin bilgi ve dini bilgi anlayışları benimsenen eğitim felsefesi, müfredat ve içeriğe ek olarak din öğretimi süreçlerinin sınırlarını şekillendiren bir unsur olarak karşımıza çıkmaktadır.Bu araştırmada, Din Kültürü ve Ahlak Bilgisi dersi öğretmenleri ile Anadolu imam hatip lisesi meslek dersi öğretmenlerinin, kendi görüşleri üzerinden, bilgi ve dini bilgi anlayışlarının ortaya konulması hedeflenmiştir. Araştırma grubu Malatya ili merkez ilçelerinde görev yapan toplam 21 Din Kültürü ve Ahlak Bilgisi dersi öğretmeni ile Anadolu imam hatip lisesi meslek dersi öğretmenlerinden oluşmaktadır. Araştırmada nitel araştırma yöntemi, veri toplamada ise mülakat tekniği kullanılmıştır. Veriler, yarı yapılandırılmış sorulardan oluşan mülakatlar ile toplanmıştır. Elde edilen verilere içerik analizi uygulanmıştır. Araştırmada “öğretmenlerin bilgi ve dini bilgi anlayışları” teması; “bilgi anlayışları, dini bilgi kaynakları” ve “bilgi ve dini bilgi ayrımı” kategorileri altında ele alınmıştır. Araştırmanın sonuçlarına göre öğretmenler bilgi ve dini bilgiyi İslam bilgi anlayışı ekseninde değerlendirmektedirler.

Yükseköğretim Öğrencilerinin ‘Uzaktan Eğitim’ Kavramına İlişkin Metaforik Algıları: Kilis 7 Aralık Üniversitesi İslami İlimler Fakültesi Örneği
Authors: GÜNGÖR Ali
Published: September 2021

Covid-19 pandemisinden sonra virüsün yayılmasını önlemek amacıyla ülkemizdeki yükseköğretim kurumları derslerini uzaktan eğitim yoluyla vermeye başlamıştır. Klasik uzaktan eğitimden farklı olarak, öğrenci, öğretici ve öğretim kurumlarının hazırlıksız yakalandığı bu olağan dışı uzaktan eğitim uygulamalarının niteliklerinin bilinmesine ihtiyaç vardır. Bu ihtiyaçtan hareketle yükseköğretim öğrencilerinin “uzaktan eğitim” kavramına ilişkin metaforik algılarını belirlemeyi amaçlayan bu çalışma, nitel araştırma yöntemlerinden olgubilim (fenomenoloji) deseninde tasarlanmıştır.Araştırmanın katılımcılarını, 2020-2021 öğretim yılında Kilis 7 Aralık Üniversitesi İslami İlimler Fakültesinin değişik sınıflarında öğrenim gören, uzaktan eğitime köy, ilçe ve il gibi farklı yerleşim birimlerinden katılan 197 kız ve erkek öğrenci oluşturmaktadır. Veriler, Covid 19 pandemisinden dolayı zorunlu olarak uzaktan eğitime devam eden öğrencilere “Uzaktan eğitim…… gibidir. Çünkü……..” ifadesindeki boşluklara uygun bir metafor ve metaforun gerekçesini yazmalarının istendiği yarı yapılandırılmış form kullanılarak toplanmıştır.Analizler sonucunda katılımcı 197 öğrenci tarafından 167 farklı metafor üretildiği tespit edilmiştir. Üretilen metaforlar olumsuz temasına ait 9 ve olumlu temasına ait 2 alt tema olmak üzere toplam 11 alt tema altında toplanmıştır. Araştırmada üretilen metaforlar incelendiğinde öğrencilerin uzaktan eğitime yönelik algılarının çoğunlukla olumsuz olarak ifade edildiği sonucuna ulaşılmıştır. Uzaktan eğitimle ilgili olumsuz görüş belirten öğrenciler, en çok metafor ürettikleri “aldatıcı” ve “yapay” temasında, uzaktan eğitimin yüzyüze eğitimin yerini tutmaya çalışan fakat ne kadar ona benzemeye çalışsa da onun özelliklerine sahip olamadığını gösteren metaforlara yer vermişlerdir.Olumlu temasında olan metaforlar ise iki alt temadan oluşmaktadır. “Avantaj” temasında öğrenciler uzaktan eğitimin kendilerine hem evde olmanın konforunu hem de öğrenime devam etmenin avantajını sağladığını ifade etmişlerdir. “Gerekli” temasında ise, uzaktan eğitim, pandemi sürecinde yüzyüze eğitimin yerini doldurması ve eğitimde kesinti yaşanmaması için bir gereklilik olarak dile getirilmiştir.Öğrencilerin uzaktan eğitimle ilgili ürettikleri metaforlar çoğunlukla olumsuz olmasına rağmen, katılımcı öğrencilerin eğitim aldığı İslami İlimler Fakültesinde hiçbir öğrencinin pandemi sürecinde kayıt dondurma yolunu tercih etmedikleri bilgisi alınmıştır. Bütün bu veriler pandemi sürecinin başında ortaya çıkan bazı olumsuzlukların zamanla aşıldığı ve öğrencilerin yukarıda sayılan olumsuzluklara rağmen uzaktan eğitime uyum sağlamaya başladıkları anlamında değerlendirilebilir.
Peace (Re)building Initiatives: Insights from Southern Kaduna, Nigeria
Authors: Maiangwa Benjamin
Published: September 2021

Violent conflicts and crime have reached new heights in Nigeria, as cases of kidnapping, armed banditry, and communal unrests continue to tear at the core of the ethnoreligious divides in the country. Southern Kaduna has witnessed a virulent spree of communal unrest in northern Nigeria over the last decade due to its polarized politics and power differentials between the various groups in the area, particularly the Christians and Muslims, who are almost evenly split. In response to their experiences of violence, the people of that region have also shown incredible resilience and grit in transforming their stress and suffering. This policy note focuses on the transformative practices of the Fulani and other ethnic communities in southern Kaduna in terms of how they problem-solve deep-seated socio-political rivalries and violent relations by working through their shared identity, history, and cultures of peace. The note explores how peace practitioners and donor agencies could consolidate local practices of sustaining peace as complementary or alternative resources to the state’s liberal system.

A evolução das estratégias publicitárias, especialmente no ambiente virtual, impôs uma revisão de entendimentos consolidados em torno da responsabilidade civil pela publicidade ilícita. A análise teleológica e sistemática do Código de Defesa do Consumidor brasileiro levou à conclusão de que não haveria lacuna e a responsabilidade poderia ser atribuída, solidariamente, a todos os agentes da publicidade, incluindo a personalidade ou influencer digital, o que situa a legislação brasileira no mesmo patamar da legislação portuguesa.
Evaluation of Physical, Spatial and Demographic Expansions in Ilam City from 1956 to 2016
Authors: Mirzaei Karamreza
Published: September 2021

The physical and spatial expansion of cities, which often taken place without planning, caused numerous environmental, health, economic and social problems. This study investigates the physical, spatial, and demographic development and expansion of Ilam city in Iran for over 60 years. To achieve these goals, library studies, data analysis, and field studies were applied. The process of development in Ilam and its demographic changes from 1956 to 2016 has been presented, and then, the spatial-physical expansion of the city is evaluated. The results showed that several factors had impacted the physical development and expansion of Ilam. The highest growth was observed between 1976 and 1986. Also, the development of the city has been more horizontal. The study results show the correlation, intensity, extension, and mechanism of conversion and land-use change in Ilam city and embody its spatial-physical expansion.
Ethno-Religious Struggle and Human Insecurity in the Fledging Nigerian Democracy since 1999
Authors: Eze Malachy Chukwuemeka
Published: September 2021

Religious and ethnic identity clashes laid the structure of the Nigerian state in 1914, which transmogrified into and characterized the struggle for control of power and distribution of national resources. This paper explores the nature and manifestation of these conflicts since 1999. It seeks to find out if ethno-religious struggles led to the emergence of major conflicts in Nigeria since 1999, their impact on human insecurity, and the influence of politics on the conflicts. This inquiry is designed in line with a one-shot case study, while literature survey and ex post facto methods were adopted as methods of data collection. Trend analysis is adopted for data analysis. Analysis reveals that ethno-religious struggles were the primary progenitor of conflicts in Nigeria since 1999, and have debilitating consequences while politics exacerbated ethno-religious conflicts. Upholding Nigeria's circular state and implementing the National Political Reforms Conference Report is the panacea for ethno-religious conflicts in Nigeria.
The Cross-sectional Shape and Height Expansion of Coronal Loops: High-resolution Coronal Imager (Hi-C) Analysis of AR 12712
Authors: Williams Thomas , Walsh Robert W. , Morgan Huw
Published: September 2021

Coronal loop observations have existed for many decades yet the precise shape of these fundamental coronal structures is still widely debated since the discovery that they appear to undergo negligible expansion between their footpoints and apex. In this work a selection of eight EUV loops and their 22 sub-element strands are studied from the second successful flight of NASA’s High-resolution Coronal Imager (Hi-C 2.1). Four of the loops correspond to open fan structures with the other four considered to be magnetically closed loops. Width analysis is performed on the loops and their sub-resolution strands using our method of fitting multiple Gaussian profiles to cross-sectional intensity slices. It is found that while the magnetically closed loops and their sub-element strands do not expand along their observable length, open fan structures may expand an additional 150% of their initial width. Following recent work, the Pearson correlation coefficient between peak intensity and loop/strand width are found to be predominantly positively correlated for the loops (≈88%) and their sub-element strands (≈80%). These results align with the hypothesis of Klimchuk & DeForest that loops and—for the first time—their sub-element strands have approximately circular cross-sectional profiles.
Ice Inheritance in Dynamical Disk Models
Authors: Bergner Jennifer B. , Ciesla Fred
Published: September 2021

The compositions of planet-forming disks are set by a combination of material inherited from the interstellar medium and material reprocessed during disk formation and evolution. Indeed, comets and primitive meteorites exhibit interstellar-like isotopic ratios and/or volatile compositions, supporting that some pristine material was incorporated intact into icy planetesimals in the solar nebula. To date, the survival of volatile interstellar material in the disk stage has not been modeled using realistic disk physics. Here, we present a modeling framework to track the destruction of interstellar ices on dust grains undergoing transport processes within a disk, with a particular focus on explaining the incorporation of pristine material into icy planetesimals. We find that it is difficult to explain inheritance through the local assembly of comets, as ice destruction is rapid for small (<10 μm) grains in the inner few tens of au. Instead, a plausible pathway to inheritance is to form pebbles at larger disk radii, which then drift inward to the comet-forming zone with their ices mostly preserved. Small grains beyond ∼100 au can experience ice photodissociation at the tens of percent level; however, little of the ice is actually lost from the grain, likely making this a robust site for in situ ice chemistry. Our models also indicate that many complex organic species should survive passage through the disk intact. This raises the possibility that organics synthesized in the interstellar medium can be delivered to terrestrial planets by icy-body impact and thus potentially participate in origins of life chemistry.
Gravitational Lensing Formalism in a Curved Arc Basis: A Continuous Description of Observables and Degeneracies from the Weak to the Strong Lensing Regime
Authors: Birrer Simon
Published: September 2021

Gravitationally lensed curved arcs provide a wealth of information about the underlying lensing distortions. Extracting precise lensing information from extended sources is a key component in many studies aiming to answer fundamental questions about the universe. To maintain accuracy with increased precision, it is of vital importance to characterize and understand the impact of degeneracies inherent in lensing observables. In this work, we present a formalism to describe the gravitational lensing distortion effects resulting in curved extended arcs based on the eigenvectors and eigenvalues of the local lensing Jacobian and their directional differentials. We identify a nonlocal and nonlinear extended deflector basis that inherits these local properties. Our parameterization is tightly linked to observable features in extended sources and allows one to accurately extract the lensing information of extended images without imposing an explicit global deflector model. We quantify what degeneracies can be broken based on specific assumptions about the local lensing nature and assumed intrinsic source shape. Our formalism is applicable from the weak linear regime to the semi-linear regime and all the way up to the highly nonlinear regime of highly magnified arcs of multiple images. The methodology and implementation presented in this work provides a framework to assessing systematics, to guide inference efforts in the right choices in complexity based on the data at hand, and to quantify the lensing information extracted in a model-independent way (https://github.com/sibirrer/curved_arcs).
