Published: December 2020

AbstractBackgroundSynthesize new complexes of Ag(I) to enhance efficacy or stability and also, pharmacological activities on the operation of pyrazolone's biological properties.ResultsEfficient and high yielding pathways starting from the versatile and readily available 3-methyl-1-phenyl-5-pyrazolone by Knoevenagel condensation of a sequence of 4-arylidene-3-methyl-1-phenyl-5-pyrazolone derivatives (2a-c) have been formed by the reaction of various substituted aromatic aldehydes Used as ligands to synthesize Ag(I) chelates. Synthesized compounds and their complexes have been characterized by elemental analysis, magnetic and spectroscopic methods (IR,13C,1HNMR, mass) and thermal analysis. The spectrophotometric determinations suggest distorted octaedral geometry for all complexes. Both ligands and their metal complexes have also been tested for their antibacterial and antifungal efficacy.ConclusionsNewly synthesized compounds have shown potent antimicrobial activity. The results showed that the complex 's high activity was higher than its free ligands, and that Ag(I)-L3had the highest activity.

Abstract
Background
Cryptosporidiosis is an acute and short-term infection which can lead to severe diarrhea (intestinal cryptosporidiosis) associated with a persistent cough in the host with immune system defect. This systematic review and meta-analysis was conducted to estimate the prevalence of animal Cryptosporidium species and the corresponding epidemiological aspects in Iran.

Methods
In this study, all original research articles relating to the animal cryptosporidiosis in Iran were collected from reliable databases using keywords. A meta-analysis was conducted separately for each subgroup, and heterogeneity among the studies was performed using the Q and I2 tests. Furthermore, it should be noticed that the significance level in the statistical analysis with the Comprehensive Meta-analysis software was considered to be less than 0.05. Finally, meta-analysis results were shown in forest plot with a 95% CI.

Results
In total, 4795 studies were included in the initial screening. Duplicated or non-original studies and the ones which did not meet our considered criteria were excluded from the list. Out of the 100 articles included in our first list for the meta-analysis, 40, 16, 13, 10, 9, 7, and 5 were done on cattle and calves, birds, dogs, sheep, rodents, camels, and horses, respectively. The prevalence rate of cryptosporidiosis among the birds, horses, rodents, camels, dogs, cattle, and sheep in Iran was estimated to be 7.5%, 19.5%, 20.8%, 8.4%, 4.9%, 14.4%, and 9.1%, respectively.

Conclusion
The different Cryptosporidium species have been found in different regions of Iran. Geographical region, climate, and domestic animals are considered as factors responsible for animal cryptosporidiosis prevalence in the area. Moreover, this parasite is zoonotic which causes disease in animals as well as humans which can result in economic loss.

Authors: Strzepka Jessica , Tian Frances , Nassani Najib , Garcia-Bedoya Olga , Yazici Cemal 
Published: December 2020

ABSTRACT
Cocaine use is prevalent worldwide and affects multiple organ systems. Ischemia of the esophagus and small bowel are examples of its gastrointestinal complications. Cocaine-induced pancreatitis is a rare entity. Only 8 cases of cocaine-induced pancreatitis have been described in the literature. We present a rare case of a 61-year-old man cocaine user who presented with his first episode of acute pancreatitis (AP) in which common etiologies of AP were excluded. In addition, we explore the pathophysiology of cocaine-induced AP.
Faculty members’ planned technology integration behaviour in the context of a faculty technology mentoring programme
Authors: Cilsalar Sagnak Hatice , Baran Evrim 
Published: December 2020

This qualitative case study aimed to examine faculty members’ perceived behaviour regarding the use of technology in their classrooms. The behavior was examined within the framework of the decomposed theory of planned behavior. The theory states that technology integration behaviour is directly related to intention and perceived behaviour control and indirectly related to attitude, subjective norms and perceived behaviour control. Data sources included semi-structured interviews conducted with 17 faculty members who participated in a faculty technology mentoring programme implemented at a large public university in Turkey over a semester of 4 months’ duration. The data analysis revealed that the factors affecting faculty members’ planned technology integration behaviour were related to their intentions, attitude, subjective norms and perceived behaviour control, as explained in the theory. Faculty members identified a number of student-related, faculty-related and context-related challenges in technology integration. The recommendations arising from the study are to support and sustain faculty members’ technology integration in higher education classrooms.
Implications for practice or policy:

Technology mentoring programs can improve faculty teaching practices with technology in higher education classrooms.
Faculty members’ technology integration behaviour can be supported by addressing the challenges, including lack of time and motivation, insufficient technological knowledge and classroom management problems.
The technology integration awareness of faculty members can be developed by improving the teaching and learning environment with the support of administrators, peers and students and providing the required time and incentives to integrate technology.
Towards faster feedback in higher education through digitally mediated dialogic loops
Authors: Willis Jill , Gibson Andrew , Kelly Nick , Spina Nerida , Azordegan Jennifer , Crosswell Leanne 
Published: December 2020

How feedback is understood and enacted has shifted from the traditional practice of providing individual feedback on summative tasks at key points to a more ongoing series of dialogues between the teacher and students during the teaching period. This paper reports on the experiences of designing faster feedback through weekly dialogic feedback loops to enhance students’ personal connection to their learning while providing teachers with faster, actionable feedback data to inform learning design. A pragmatic inquiry considered how benefits might potentially be amplified through the use of digital technologies. Data included student reflections collected via the GoingOK web application, interviews and focus groups. The findings identify and theorise four types of digitally mediated feedback loops: students in computer-mediated dialogue with themselves; students and teachers in dialogue with each other; the reflection on how feedback informed learning; and the sociotechnical dialogue informing ongoing technical design. Three design dilemmas that were experienced by teachers as they enacted digitally mediated dialogic feedback loops are articulated, alongside the principles that enabled responsive design. Understanding these design elements is fundamental if automation of some parts of the feedback loop through reflective writing analytics is to be considered both feasible and desirable.
Implications for practice or policy:

Digitally mediated feedback loops can facilitate faster feedback, enabling students to reflect on their learning and providing teachers with access to new insights about diverse learners.
Feedback technology can challenge existing ideas about feedback.
Faster feedback can save teachers time, but efficiencies are likely to depend on an increased human workload in the short term as automation technologies can be slower to develop.
Sociotechnical innovation requires collective dialogue between educators and digital developers, across asynchronous timelines.
And You Will Be Amazed: The Rhetoric of Authority in the Greek Magical Papyri
Authors: Edmonds Radcliffe G. 
Published: December 2020

AbstractAn analysis of the rhetorical strategies used in the so-called Greek Magical Papyri to bolster the authority of the authors provides insight into the authors of these texts and their intended audiences. This article reviews the scholarship on the identity of the composers of the Greek Magical Papyri and explores the rhetorical strategies used in the texts to create authority, before comparing the dominant strategies in the Greek Magical Papyri with similar ones in other kinds of recipe collections, specifically alchemical and medical texts. The authors of the recipes in the Greek Magical Papyri make little use of the traditional authority of the temples but instead justify their claims of superiority with reference to the amazing efficacy of the procedures they describe. The direct, second person address in formulas such as “and you will be amazed” suggests that the intended audience was imagined not as potential clients who need to be convinced of the author’s expertise, but rather as potential practitioners interested in impressing their own clients.
Nommer les dieux hittites : au sujet de quelques épithètes divines
Authors: Mouton Alice 
Published: December 2020

Abstract
After a short overview of Hittite divine epithets (Anatolia of the second half of the second millennium BCE), this paper explores the attestations of two particular divine names, namely “the bloody god U.GUR” and “the vengeful nakkiu-/nakkiwa‐s.” These entities are studied in context in order to determine their identity and functions. Through this contextual analysis, it appears that these supernatural entities are held responsible for various anomalies in the context of Luwian rituals probably coming from the Lower Land (south-central Anatolia).
Creation in the Poimandres and in Other Creation Stories
Authors: Graf Fritz 
Published: December 2020

Abstract
My paper develops from the observation that the cosmogonies in Ovid’s Metamorphoses and the Hermetic Poimandres are related to each other. After an analysis of Ovid’s text as an example of a diakrisis cosmogony in which the world is created by the sorting out of its originally confused elements, I give a short overview of the history of this type of cosmogony before Ovid. I then analyze the respective cosmogony in the Poimandres as another example of the same typology. A look at the use of diakrisis cosmogonies in late antiquity, including in the first ‘Moral Poem’ of Gregory of Nazianzus, closes the paper and demonstrates the attraction of this cosmogonical model in the Imperial epoch.
Christliche Weltherrschaft im ›Parzival‹
Authors: Haferland Harald 
Published: December 2020

Abstract
The article takes the open ending of ›Parzival‹ as its point of departure. It analyses information about the expansion of the grail community: The grail is at the heart of a hidden take-over of world domination. This idea originates in the military orders. In ›Parzival‹, it is associated with an eschatological perspective. However, Wolfram obscures the beginning of the eschaton, just as he obscures the topographical location of Munsalvaesche. The idea of world domination goes back to the Third Crusade and the role of Frederick Barbarossa. It can be assumed that Wolfram had direct contact with men who had taken part in the campaign. His conception of the grail can be traced to the Black Stone of the Kaaba, to which it constitutes a Christian counterpart.
Identification of dental pain sensation based on cardiorespiratory signals
Authors: Teichmann Daniel , Hallmann Alexander , Wolfart Stefan , Teichmann Maren 
Published: December 2020

AbstractThe aim of this study is to investigate the feasibility of the detection of brief periods of pain sensation based on cardiorespiratory signals during dental pain triggers. Twenty patients underwent dental treatment and reported their pain events by pressing a push button while ECG, PPG, and thoracic effort signals were simultaneously recorded. Potential pain-indicating features were calculated from the physiological data (sample length of 6 s) and were used for supervised learning of a Random forest pain detector. The best feature combination was determined by Feature forward selection. The best feature combination comprises nine feature groups consisting of four respiratory and five cardiac related groups. The final algorithm achieved a sensitivity of 87% and a specificity of 63% with an AUC of 0.828. Using supervised learning it is possible to train an algorithm to differentiate between short time intervals of pain and no pain solely based on cardiorespiratory signals. An on-site and real-time detection and rating of pain sensations would allow a precise, individuum- and treatment-tailored administration of local anesthesia. Severe phases of pain could be paused or avoided, this would allow more comfortable treatment and yield better patient compliance.
Adsorption and sugarcane-bagasse-derived activated carbon-based mitigation of 1-[2-(2-chloroethoxy)phenyl]sulfonyl-3-(4-methoxy-6-methyl-1,3,5-triazin-2-yl) urea-contaminated soils
Authors: Ahmad Khuram Shahzad , Amjad Iqra , Ali Daoud 
Published: December 2020

AbstractBurgeoning pesticide usage in agriculture sector required to be evaluated by assessing the adsorption rate in soils. The herbicide triasulfuron was used in this research to analyze its sorption behavior in seven distinct soils using batch equilibrium methodology. The adsorption coefficient (Kd) values ranged from the 3.32 to 29.7 µg/mL. Peshawar soil displayed the highest Kd value because of the distinct physiochemical properties when compared with the other six samples. Gibbs free energy exhibited negative values displaying less contact between soil particles and pesticides, showing the exothermic nature of the phenomena. A negative association was observed between the pH of the soil samples and Kd (R2 = −0.71) but a direct relation with the organic content (R2 = 0.74). Triasulfuron mitigation was performed by the economical remediation of soils using acid-activated charcoal prepped from Saccharum officinarum husk. Activated carbon derived from biomass displayed the great potential for triasulfuron removal from soils.
Ultrasound prenatal diagnosis of a de novo 14q distal duplication associated with foetal anomalies: a case report
Authors: Garofalo Anna , Lanna Mariano , Ronzoni Luisa , Toto Valentina , Izzo Giana , Rustico Maria Angela 
Published: December 2020

Abstract

Objectives
Partial trisomy 14q is a rare chromosomal abnormality with an extremely variable phenotype ranging from mild to severe forms of malformation. Most of the cases described in literature are postnatal clinical findings although few prenatal cases have been reported.

Case presentation
A 33-year-old woman at 21+6 weeks’ gestation was referred to our hospital for a detailed foetal ultrasound with suspected partial agenesis of corpus callosum and ureterocele. On examination, we found a short corpus callosum and ureterocele with a duplicated right renal collecting system. Moreover, there was an intrarotation of left foot with a prominent part departing from the ankle, both thighs appeared thicker, a thickening of the nuchal fold, a mild hypertelorism and a thick heterogeneous placenta. The patient underwent magnetic resonance imaging (MRI), which confirmed the foetal anomalies. The couple opted for a termination of pregnancy. Chromosome analysis and molecular karyotyping of amniocytes revealed a de novo rearrangement of chromosome 14 with an interstitial gain 14q31.1–14q32.22 and a terminal deletion 14q32.33.

Conclusions
The majority of partial trisomy 14q reporter are postnatal diagnoses. Improvement in the quality of foetal imaging and molecular techniques have made possible to identify many genetic syndromes prenatally. In our opinion, anomalies of the brain, urinary system and limbs may be the core findings of trisomy 14q. To our knowledge, no such case has ever been described previously.
Effects of rotational speed on the Al0.3CoCrCu0.3FeNi high-entropy alloy by friction stir welding
Authors: Lin Po-Ting , Wu Chan-Sheng , Peng Chun-Hao , Tsai Che-Wei , Sato Yutaka S. 
Published: December 2020

AbstractWelding and relevant studies are indispensable to employ high-entropy alloys for practical applications. In this study, Al0.3CoCrCu0.3FeNi high-entropy alloy with single FCC phase was used to make “bead-on-plate” friction stir welds at different rotational speeds, and the effects on microstructure and mechanical properties were studied. Several banded structures containing oxide or nitride particles were observed in the stir zone (SZ), and the chemical wear of the polycrystalline cubic boron nitride tool was confirmed. The microhardness distribution of the welds showed higher hardness in the SZ because of grain refinement and the presence of deformed grains. The electron backscattered diffraction results suggested that the high-entropy alloy with low stacking-fault energy experienced recrystallization during friction stir welding, which was similar to other conventional materials with low stacking-fault energy.
Damage accumulation and lifetime prediction of fiber-reinforced ceramic-matrix composites under thermomechanical fatigue loading
Authors: Li Longbiao 
Published: December 2020

AbstractIn this paper, the damage accumulation and life prediction in fiber-reinforced ceramic-matrix composites (CMCs) subjected to thermomechanical fatigue (TMF) loading are investigated. The relationships between TMF damage mechanisms, fatigue hysteresis-based damage parameters, fraction of broken fiber, and applied cycles are established. Evolution of fatigue hysteresis dissipated energy, fatigue hysteresis modulus, fatigue peak strain, fatigue broken fiber fraction versus applied cycle curves, and the fatigue life S–N curves is analyzed. Damage accumulation and fatigue life of cross-ply silicon carbide/magnesium aluminosilicate composite under in-phase (IP)- and out-of-phase (OP)-TMF and isothermal fatigue (IF) loading are predicted. Under the same fatigue peak stress, the fatigue lifetime decreases from IF loading at 566°C to IF loading at 1,093°C, IP-TMF and OP-TMF. The TMF loading significantly reduced the fatigue lifetime of CMCs.
Pruning and repopulating a lexical taxonomy: experiments in Spanish, English and French
Authors: Nazar Rogelio , Balvet Antonio , Ferraro Gabriela , Marín Rafael , Renau Irene 
Published: December 2020

AbstractIn this paper we present the problem of a noisy lexical taxonomy and suggest two tasks as potential remedies. The first task is to identify and eliminate incorrect hypernymy links, and the second is to repopulate the taxonomy with new relations. The first task consists of revising the entire taxonomy and returning a Boolean for each assertion of hypernymy between two nouns (e.g.brie is a kind of cheese). The second task consists of recursively producing a chain of hypernyms for a given noun, until the most general node in the taxonomy is reached (e.g.brie → cheese → food →etc.). In order to achieve these goals, we implemented a hybrid hypernym-detection algorithm that incorporates various intuitions, such as syntagmatic, paradigmatic and morphological association measures as well as lexical patterns. We evaluate these algorithms individually and collectively and report findings in Spanish, English and French.

Published: December 2020

Abstract

Objectives
To evaluate the relationship between Coronavirus Disease 2019 (COVID-19) in pregnancy and adverse perinatal outcomes. The secondary aim is to analyze the diagnostic value of hematologic parameters in COVID-19 complicated pregnancies.

Methods
The current study is conducted in a high volume tertiary obstetrics center burdened by COVID-19 pandemics, in Turkey. In this cohort study, perinatal outcomes and complete blood count indices performed at the time of admission of 39 pregnancies (Study group) complicated by COVID-19 were compared with 69 uncomplicated pregnancies (Control group).

Results
There was no significant difference between the obstetric and neonatal outcomes of pregnancies with COVID-19 compared to data of healthy pregnancies, except the increased C-section rate (p=0.026). Monocyte count, red cell distribution width (RDW), neutrophil/lymphocyte ratio (NLR), and monocyte/lymphocyte ratio (MLR) were significantly increased (p<0.0001, p=0.009, p=0.043, p<0.0001, respectively) whereas the MPV and plateletcrit were significantly decreased (p=0.001, p=0.008) in pregnants with COVID-19. ROC analysis revealed that the optimal cut-off value for MLR was 0.354 which indicated 96.7% specificity and 59.5% sensitivity in diagnosis of pregnant women with COVID-19. A strong positive correlation was found between the MLR and the presence of cough symptom (r=41.4, p=<0.0001).

Conclusions
The study revealed that, pregnancies complicated by COVID-19 is not related with adverse perinatal outcomes. MLR may serve as a supportive diagnostic parameter together with the Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) in assessment of COVID-19 in pregnant cohort.

Zur militärischen Mobilmachung in der DDR
Authors: Wenzke Rüdiger 
Published: December 2020

Zusammenfassung
Der Beitrag beschäftigt sich mit dem militärischen Mobilmachungssystem in der DDR. Im Rahmen der Umstellung von Frieden auf Krieg in allen gesellschaftlichen Bereichen nahm die Mobilmachung der Nationalen Volksarmee (NVA) einen zentralen Platz ein. Ihre Struktur-, Mobilmachungs- und Einsatzplanungen waren eng miteinander verknüpft. Im Mobilmachungsfall sollten unter anderen fünf Divisionen der NVA-Landstreitkräfte auf der Basis sogenannter Ausbildungszentren personell und materiell aufgestellt werden, um nach 48 Stunden Mobilmachung und weiteren 48 Stunden Ausbildung voll einsatzbereit zu sein. Ständige Kontrollen und Überprüfungen unterstrichen die Bedeutung der Mobilmachungsarbeit in den ostdeutschen Streitkräften. Die militärische Mobilmachung als Teil des gesamtstaatlichen Mobilmachungssystems förderte die Militarisierung der ostdeutschen Gesellschaft in erheblichem Maße.
„Die schönste griechische Stadt“. Syrakus bei Cicero und Silius Italicus
Authors: Schwameis Christoph 
Published: December 2020

AbstractBoth in the fourth book of Cicero’sDe signis(Verr. 2,4) and in the fourteenth book of Silius Italicus’Punica, there are descriptions of the city of Syracuse at important points of the texts. In this paper, both descriptions are combined and for the first time thoroughly related. I discuss form and content of the accounts, show their functions in their oratorical and epic contexts and consider their similarities. The most important facets, where the descriptions coincide in, seem to be their link to Marcellus’ conquest in the Second Punic War, the resulting precarious beauty of the city and the specifically Roman perspective on which theseekphraseisare based.
