Authors: Szymańska-Czerwińska Monika , Jodełko Agnieszka , Osiński Zbigniew , Niemczuk Krzysztof
Published: December 2022

Introduction

The intracellular bacterium Coxiella burnetii is the aetiological agent of Q fever, a zoonosis affecting many animal species worldwide. Cattle and small ruminants are considered the major reservoirs of the bacteria and they shed it through multiple routes.

Material and Methods

A total of 2,180 sera samples from 801 cattle herds in all Polish voivodeships were tested by ELISA for the presence of specific antibodies. Milk samples were obtained from seropositive cows in 133 herds as part of a separate study. The milk samples were examined by ELISA and real-time PCR tests.

Results

Seroprevalence at the animal level was 7.06% and true positive seroprevalence was 6.0% (95% confidence interval (CI) 1.1–9.4). Seroprevalence at the herd level was estimated at 11.1% and true positive seroprevalence was 10.5% (95% CI 3.2–15.8). Shedding of the pathogen in milk was detected by real-time PCR in 33 out of 133 tested herds (24.81%, 95% CI 17.74–33.04%) and the presence of C. burnetii antibodies was confirmed in 85 of them (63.9%, 95% CI 55.13–72.05%). The highest level of conformity between ELISA and real-time PCR results was obtained for bulk tank milk samples.

Conclusion

Coxiella burnetii infections are quite common in cattle herds across the country, which emphasises the crucial roles of surveillance and adequate biosecurity measures in the prevention and limitation of Q fever spread in Poland.

Authors: Pramayoza Dede , Birowo Pandu
Published: December 2022

This study discusses the transition of performances dramaturgy during the Covid-19 pandemic from analog to digital formats, from live performances commonly called staging to mediated performances which can be called performance streaming. The aim of study is to understand the application of ‘dramaturgical tactics’; and the reasons. Applying the dramaturgical analysis method investigation is directed at the transformation process from the basic concept of the performance to the practice of its presentation. The research departs from the premise that a dramaturgical process, namely the pre-production, production, and presentation of performance is permanently connected by a dramaturgical awareness. The analysis was carried out: (1) the idea of streaming; (2) performance technique; and (3) the form of performance streaming. Research shows that the critical changes in dramaturgy during the pandemic were triggered by the necessity to shift the mode of performance from staging to streaming, resulting in three dramaturgical awareness about transition, namely: (1) medium: from analog to digital performance; (2) creativity: from performer to content creator; and (3) the spectatorship: from spectator to voyeur. Perubahan Dramaturgi di Masa Pandemi: Dari Pementasan ke Siaran. Artikel ini membahas perihal transisi dramaturgi pertunjukan di masa pandemi Covid-19 dari format analog ke format digital, dari moda pertunjukan langsung yang lazim dinamakan pementasan ke pertunjukan termediasi yang dapat dinamakan siaran pertunjukan. Tujuannya untuk memahami bentuk penerapan ‘siasat dramaturgi’ serta alasan di baliknya. Mengunakan metode analisis dramaturgis, berupa investigasi atas proses transformasi dari konsep dasar pertunjukan menuju praktik presentasinya, penelitian berangkat dengan premis bahwa suatu proses  dramaturgi, yakni tahap pra-produksi, produksi, dan presentasi pertunjukan selalu terhubung oleh satu kesadaran dramaturgis. Analisis dilakukan terhadap: (1) gagasan siaran pertunjukan; (2) teknik siaran pertunjukan; dan (3) bentuk siaran pertunjukan. Penelitian menunjukkan bahwa, perubahan penting dramaturgi di masa pandemi dipicu oleh suatu keharusan untuk memindahkan moda pertunjukan dari pementasan ke siaran, menghasilkan tiga kesadaran dramaturgis tentang peralihan, yakni: (1) medium: dari pementasan analog ke siaran digital; (2) kreativitas: dari penampil menjadi pembuat konten; dan (3) kepenontonan: dari spektator menjadi voyeur.

Vaccination is the best strategy to prevent the transmission and spread of some diseases, including the coronavirus disease of 2019 (COVID-19). Various COVID-19 vaccines are now available with high efficacy and safety, and they proved their efficacy to reduce the mortality rate due to COVID-19. However, the uptake of the general population to the vaccine is still low. To assess the level of COVID-19 vaccine acceptance among the general population by reviewing the previous studies conducted on this subject. PubMed and Google scholar databases were explored starting from 2021 to 2022. The search terms included "Acceptance, COVID-19 vaccine, Attitude, General population, Acceptance rate, COVID-19 vaccination," which were used in a variety of combinations to obtain all possible articles. The inclusion criteria were original articles in English Language where the research was conducted among the general population and reported the acceptance of the general population regarding the COVID-19 vaccine. A total of 1,641 articles were obtained; eight articles met the inclusion criteria and were included in our analysis. The eight studies included a total number of 22,938 participants and were conducted in eight different countries. The range of acceptance rate was 37.4% to79.8%. There was a moderate acceptance rate of the general population regarding the COVID-19 vaccine. The factors associated with vaccine acceptance were either related to the individuals or the vaccine. Increasing the knowledge of the general population about the COVID-19 vaccine is the key factor to increasing the acceptance rate.

Published: December 2022

Background: Despite a drastic increase among smokers using e-cigarette products in an attempt to wean off more harmful combustible cigarettes, there is no clear evidence promoting either the use of e-cigarettes (e-cigs) as a cessation device or understanding of the potential risks and benefits of these products, as per the U.S. Food and Drug Administration.
Case Presentation: This case has an unusual presentation of methemoglobinemia in the emergency department for the same patient twice, immediately after using e-cigs/vapes on two separate occasions.
Results: There is a possible association between e-cigarette use and methemoglobinemia. The aforementioned patient was successfully treated with the ordinary management for methemoglobinemia: methylene blue and supportive care.
Conclusion: E-cigarette use has many unrecognized and possibly fatal complications. Based on our observations, we recommend a further clinical trial to study e-cigs as a causation factor for methemoglobinemia.

Authors: KARAKULAK Ertuğrul
Published: December 2022

In this study, a QRS detection algorithm with a low processing load based on time-domain thresholding is proposed. The ECG signal is filtered only with a low pass filter to reduce the computational load. After the filtering, derivation and squaring are also performed. In the Thresholding stage, a linear decreasing threshold voltage method using addition operation instead of multiplication is proposed. Simulations on MIT-BIT Arrhythmia Database have yielded 99.2925% sensitivity (% Se) and 99.6759% positive predictivity (+ P). The proposed algorithm is compared with two similar algorithms in terms of both performance and processing load. It is shown that the proposed algorithm is better than its counterparts, especially in terms of processing load. However, it is observed that it gave worse results in terms of Sensitivity (% Se).

Plasma–Wall Interaction Model for Erosion of Materials Under Ion Bombardment
Authors: Logarzo Hernan J. , Rimoli Julian J.
Published: December 2022

Understanding the evolution and behavior of materials exposed to plasma is critical for the design of future electric propulsion devices. As ions are ejected from the device generating thrust, they also impact the ceramic walls. This induces wall erosion, ultimately exposing the magnetic circuit, leading to malfunction and failure of the device. There are several models that try to predict this effect by accounting for material sputtering. However, they cannot predict the millimeter-scale surface features that develop after prolonged exposure. In this work, we address this issue by introducing a plasma–material interaction model able to capture the evolution of surface features at the macroscopic scale on materials exposed to plasma over a long period of time. Results show that the model is able to reproduce not only the mean erosion rate but also the macroscopic anomalous ridges that appear after long exposure. Furthermore, it highlights the need to account for complex thermomechanical material behavior to be able to explain such features.
Implementation of Multidisciplinary and Multifidelity Uncertainty Quantification Methods for Sonic Boom Prediction

Published: December 2022

To advance a supersonic aircraft design process, an uncertainty quantification study is conducted for sonic boom prediction while considering uncertainties associated with flight and atmospheric conditions. The uncertainty quantification process is implemented within a multidisciplinary analyses framework and assisted with a multifidelity surrogate model based approach. The sonic boom prediction framework requires input from the flowfield pressure distribution solution to generate the near-field pressure signature of the aircraft, which is then propagated throughout the atmosphere to the ground by using aeroacoustic methods. The open-source SU2 suite is employed as a high-fidelity flow solver tool to obtain the aerodynamic solution, while in-house postprocessing scripts are developed to generate the required near-field pressure signature. For low-fidelity flow analysis, A502 PAN AIR, a higher-order panel code which solves flows around slender bodies in low angles of attack for subsonic and supersonic regimes, is used. For nonlinear aeroacoustic propagation, NASA Langley Research Center’s code sBOOM exploits the near-field pressure signature for both high-fidelity and low-fidelity sonic boom calculations. Efficient uncertainty quantification tools are developed in house by implementing multifidelity polynomial chaos expansion and multifidelity Monte Carlo methods. Several flight and atmospheric parameters are selected to include randomness where these uncertainties are propagated into the sonic boom loudness prediction of the JAXA wing-body model, which is a low boom aircraft. Finally, an overall assessment of the multifidelity uncertainty quantification methods is presented in terms of efficiency and numerical accuracy.
Machine Learning to Classify Vortex Wakes of Energy Harvesting Oscillating Foils
Authors: Ribeiro Bernardo Luiz R. , Franck Jennifer A.
Published: December 2022

A machine learning model is developed to establish wake patterns behind oscillating foils for energy harvesting. The role of the wake structure is particularly important for array deployments of oscillating foils since the unsteady wake highly influences the performance of downstream foils. This work explores 46 oscillating foil kinematics, with the goal of parameterizing the wake based on the input kinematic variables and grouping vortex wakes through image analysis of vorticity fields. A combination of a convolutional neural network with long short-term memory units is developed to classify the wakes into three classes. To fully verify the physical wake differences among foil kinematics, a convolutional autoencoder combined with [Formula: see text]-means++ clustering is used to reveal four wake patterns via an unsupervised method. Future work can use these patterns to predict the performance of foils placed in the wake and build optimal foil arrangements for tidal energy harvesting.
Dynamic Analysis of Cylindrical Shells with Flexoelectric Actuation
Authors: Han Qiu , Yan Deng , Mu Fan , Hornsen Tzou
Published: December 2022

The converse flexoelectric effect can be utilized to actuate and control flexible structures. Assessing the precision flexoelectric actuation and control effectiveness of cylindrical shells is the main objective of this study. The application of voltage to the line electrode on the external surface of a flexoelectric patch, coupled with the bottom surface electrode layer, causes an inhomogeneous electric field to be generated, which consequently induces internal actuation stresses. The stress-induced membrane control force and bending control moment generate modal control effects, which regulate the cylindrical shell vibration. For an elastic cylindrical shell with flexoelectric actuation, the modal forces and microscopic behaviors are studied to evaluate the flexoelectric actuation effects. For the transverse direction, the electric field gradient drops sharply with increasing distance from the line electrode; thus, the induced internal actuation stresses concentrate on the upper surface. Due to the inhomogeneous electric field gradient distributions, the membrane control force and bending control moment concentrate like spikes. To evaluate the actuation effects, modal force distributions of the elastic cylindrical shell with flexoelectric actuation are analyzed with respect to design parameters, such as the flexoelectric patch thickness, line-electrode radius, cylindrical shell thickness, and shell radius.

Published: December 2022

Stevia rebaudina Bertoni and Leontopodium alpinum Cass. (Asteraceae) are valuable plants, largely applied in traditional and formal medicine. Six variants of Murashige and Skoog media containing creatine or creatine lysinate at different concentrations (1, 5 and 10 mg/l) were used. The application of creatine lysinate in the MS nutrient media influenced positively the apical growth and elongation of stevia and edelweiss in vitro plants. The higher activities of the antioxidant enzymes (SOD, APX and GPX), as well as the higher content of flavonoids and phenols, were detected in stevia compared to edelweiss. The activity of CAT was much more pronounced in edelweiss. The activities of CAT, APX and GPX were found to decrease with the addition of creatine or creatine lysinate to the culture medium while the activity of SOD increased as this tendency is better expressed in L. alpinum. The selected concentrations of creatine and creatine lysinate did not show statistically significant differences in either of thе treatments compared to control in both the species measured by free radical scavenging capacity (DPPH method).

Published: December 2022

Aedes aegypti is a principal vector of dengue, chikungunya and Zika illnesses worldwide. Because effective vaccinations or medications for the prevention and/or treatment for these illnesses are not available, vector management has been embraced as the primary method of reducing their transmission. The strategy that is often used for controlling Aedes populations is chemical insecticides; however, despite their efficiency, extensive usage of these pesticides has resulted in high operating costs, the establishment of resistant populations and undesirable non-target impacts. Therefore, the use of nanoparticles derived from multiple synthesis processes as new insecticides has recently attracted the interest of researchers. This study provides an overview of the current understanding concerning the method of action of nanoparticles against mosquitoes. Metal nanoparticles strongly influence antioxidant and detoxifying enzymes in insects, causing oxidative stress and cell death. These nanoparticles similarly inhibited acetylcholinesterase activity. Metal-based nanoparticles can potentially bind to S and P units in proteins and nucleic acids respectively resulting in decreased membrane permeability, organelle and enzyme denaturation which leads to cell death. Furthermore, they upregulate and downregulate critical insect genes, lower protein synthesis and gonadotrophin release, resulting in developmental and reproductive failure. This review critically examines insect nanotoxicology research trends and highlights the ecotoxicological effects of practical usage of nanoparticles as insecticides.

Published: December 2022

Authentication through the use of passwords usually allow users to access resources in a computer or automated installations. However, remembering such passwords is often a problem for most users due to complex nature of most stong password. As a viable alternative, graphical passwords were introduced to complement the security problems in this method of authentication. Therefore, this papr proposes the concept of a graphical password authentication system using hybrid approach. This approach that allows users to identity a number of images during the registration process and then requested to draw a pattern on each image in a pre-defined order to complete the system approach. This process is represented via a three-stage scheme which consists of the Registration phase, the Login phase and the Authentication phase (RLA). The evaluation was carried out using the comparative study that involves generation of secure graphical password. This methodology is often refered to as Educating Users to Generate Secure Graphical Password Secrets (EUSGPAS). The evaluation involved 200 purposively selected participants who were made to use the new system over six weeks. Experimental results of ESGAS and EUSGPAS indicated a mean success rate of 100%, 97%, 100% and 99%, 96%, 98.9% with a mean completion time of 29.71s and 30.89s respectively. These results indicated the merits of the proposed method over the EUSGPAS approach.

Authors: Demirtas Yunus , Kaya Ozgur , Emet Abdulsamet
Published: December 2022

Background/Aim: Proximal humerus fractures are common in elderly patients. Treatment of three and four-part fractures is especially controversial in these patients. In recent years, surgical options have been widely used, especially among shoulder surgeons. The purpose of this study was to compare clinical results of conservative and arthroplasty methods.
Methods: Between 2016 and 2020, 30 patients who were treated for Neer type 3 and type 4 proximal humeral fractures were included in the study. Patient data were evaluated retrospectively and then divided into three groups. Group 1 was treated conservatively, group 2 underwent hemiarthroplasty; and group 3 underwent reverse total shoulder arthroplasty. CONSTANT and visual analog scale (VAS) scores and radiological results at six months were evaluated retrospectively from patient records. At the last control they have been evaluated with CONSTANT, University of California/Los Angeles. (UCLA), and VAS scores.
Results: Twenty-three (76.7%) of the patients included in the study were females. The mean age was 73.5 (5.7) years. The mean follow-up period was 33 (2.5) months. The mean follow-up periods in groups 1–3 were 33.3 (2.9), 32.8 (2), and 32.2 (2.9) months, respectively. When the CONSTANT scores of the patients were compared at the sixth month, they were observed to be better in the reverse total shoulder arthroplasty group (P = 0.001). Final control CONSTANT scores in the hemiarthroplasty group were lower than in the other groups (P = 0.001) and similar in the reverse shoulder prosthesis and conservative treatment group (P = 1). When the UCLA scores of all groups were compared, the mean UCLA scores were found to be significantly higher in groups 1 and 3 compared to group 2 (P = 0.001). When the VAS scores of the patients were compared, a significant difference between all groups was detected (P < 0.05). The highest VAS scores were observed in group 2, the second highest in group 1, and the lowest in group 3.
Conclusion: For treatment of proximal humerus fractures in the elderly, patients should be evaluated according to activity levels and expectations, and surgical treatment should be suggested rather than ordered.

Türkçe eğitiminde sınıf içi uygulamalarda yaygın biçimde kullanılan ders kitaplarındaki metinlerin taşıması gereken en önemli metinsellik ölçütü tutarlılıktır. Alanyazında tutarlılık üzerine yapılan araştırmalarda “tutarlılık görünümü” adı altında kullanılan başlıklar; karşılaştırma, neden-sonuç, örneklendirme-özelleştirme, genelleştirme, amaç-sonuç, koşul ve karşıtlıktır. Bu çerçevede araştırmada ilkokul 4. sınıf Türkçe ders kitaplarındaki metinler tutarlılık açısından sorgulanmıştır. İlkokul 4. sınıf Türkçe ders kitaplarındaki metinlerin tutarlılık görünümlerini belirlemeyi amaçlayan bu araştırma, nitel araştırma yaklaşımına göre yürütülmüştür. Doküman incelemesi tekniğinin kullanıldığı araştırmada, 2022-2023 Eğitim Öğretim Yılı’nda okutulan MEB Yayınları 4. Sınıf Türkçe Ders Kitabı ile Özgün Yayınları 4. Sınıf Türkçe Ders Kitabı incelenmiştir. Her iki Yayınevine ait ders kitaplarındaki metinlerin tutarlılık görünümleri; tema, ortak tema ve metin türü özelliklerine göre kendi içinde ve karşılaştırmalı olarak incelenmiş, incelemede elde edilen verilerin çözümlenmesinde betimsel analiz kullanılmıştır. Araştırmanın sonuçlarına göre her iki yayına ait ders kitaplarındaki metinler toplu olarak değerlendirildiğinde en sık rastlanan tutarlılık görünümleri karşılaştırma, neden-sonuç, örneklendirme-özelleştirme; en az ise karşıtlık, genelleştirme, amaç-sonuç ve koşuldur. En fazla tutarlılık görünümüne Okuma Kültürü ile Sağlık ve Spor temalarında, en az ise Sanat, Doğa ve Evren, Bilim ve Teknoloji temalarında rastlanmıştır. Her iki yayının ait ortak temalarının tutarlılık görünümleri ele alındığında en fazla rastlanan tutarlılık görünümleri karşılaştırma, neden-sonuç, örneklendirme-özelleştirme; en az kullanılan tutarlılık görünümleri ise karşıtlık, genelleştirme ve koşuldur. Her iki Türkçe ders kitabındaki öyküleyici metinlerde en fazla rastlanan tutarlılık görünümü neden-sonuç, bilgilendirici metinlerde ise karşılaştırmadır. Her iki metin türünde de en az görülen tutarlılık görünümü zıtlıktır. Araştırmada, Türkçe ders kitaplarındaki metinlerin seçiminde tutarlılık ölçütüne en yüksek düzeyde yer verilmesi önerilmiştir.

Authors: Silva Fabio
Published: December 2022

Os estudos das literaturas africanas no Brasil se tornaram mais evidente após a lei de nº 10.639, de 9 de janeiro de 2003, que alterou a Lei no 9.394, de 20 de dezembro de 1996, que estabelecia “as diretrizes e bases da educação nacional”, com uma incisão para incluir currículo “oficial da Rede de Ensino a obrigatoriedade da temática ‘História e Cultura Afro-Brasileira’ na sua componente curricular”. Décadas antes, algumas universidades e professores/as foram pioneiros/as nesses estudos, inclusive uma das autoras da obra que agora se resenha, Francisca Zuleide Duarte de Souza, que em parceria com seu ex-orientanda de doutorado, Izabel Cristina de Oliveira Martins, vem dar voz e destaque a autoria feminina africana em língua portuguesa com a obra intitulada Índice de autoras das literaturas africanas de língua portuguesa.

Dünya genelinde enerji ihtiyacındaki artış ve fosil enerji kaynaklarının tükeniyor olması sebebiyle kaynakların daha verimli kullanılması gerekmektedir. Kullanılan kaynakların çevreye olan zararları ise enerji ihtiyacındaki artış ile paralel olarak artmakta ve geri dönülemez zararlara sebep olmaktadır. Renksiz dağıtılmış yanma yaklaşımı ile yakıtların çevreye olan zararlarını minimuma indirmek amaçlanmış ve bu çalışmada da renksiz dağıtılmış yanma metodu uygulanmıştır. Yanma koşulları için hazırlanmış olan bir yakıcı içerisine ön karışımlı olarak hava-yakıt karışımı gönderilmiş ve farklı koşullar altında hava fazlalık katsayısı (λ) değiştirilerek sonuçlar incelenmiştir. Hava-yakıt oranı değiştirilerek (λ=1.2 ve λ=1.7) yanma sonucu ortaya çıkan CO, CO2, NOx emisyonlarını düşürmek amaçlanmıştır. Modellemeler Ansys Fluent Student Edition yazılımı kullanılarak gerçekleştirilmiştir. Ansys Fluent yazılımında üç boyutlu sayısal modelleme için Species Transport yanma modeli ve P-1 radyasyon modeli seçilmiştir. Yanma modeli GRI-MECH kullanılmış, 64 basamaklı bir kimyasal reaksiyon oluşturulmuş ve Eddy Dissipation Concept modeli ile entegrasyonu yapılarak gerçekleştirilmiştir. Model ve reaksiyon sonucu doğrulaması için elde edilen deney sonuçlarıyla sabit yanma koşullarının karşılaştırılması yapılmıştır. Oksitleyici olarak hava kullanılmış ancak yakıt ile oksitleyici yanma odasına girmeden önce karıştırılarak kullanılmıştır. İlk koşul için hava fazlalık katsayısı λ= 1.2 karşılaştırılacak ikinci koşul için ise hava fazlalık katsayısı λ= 1.7 seçilmiş ve 10kW güç altında çalışılmıştır. Renksiz dağıtılmış yanma şartları ise yakıt hava karışımı içerisindeki oksijen oranları sırasıyla %21 O2 (renksiz dağıtılmış yanma şartlarının uygulanmadığı oran) %19 O2, %17 O2 ve %15 O2 olacak şekilde uygulanmıştır. Uygulama sonucunda ortaya çıkan yakıt hava oranları tablolarda gösterilmiş ve sonuçları karşılaştırılmıştır. Renksiz dağıtılmış yanma koşulları uygulanırken yanma odasına giren O2 konsantrasyonu oransal olarak azaltılması için seyreltici olarak N2 beslenmiş ve yanma koşuları buna göre incelenmiştir. Sonuçlar irdelendiğinde, renksiz dağıtılmış yanma ile daha homojen bir sıcaklık dağılımı elde edilirken CO2, NOX ve CO emisyonlarında önemli derecede azalmalar gözlenmiştir.

Diabetes mellitus (DM) has become a global health problem because the prevalence of diabetes mellitus continues to increase. Data from the West Sumatra Provincial Health Office (2018), DM cases totalled 44,280 cases, with a DM prevalence of 1.6% in 2018. Self-efficacy plays an important role in controlling blood sugar levels. Lack of self-efficacy causes the patient's blood sugar levels to become abnormal, resulting in a risk of complications. This research aims to study the relationship between self-efficacy and diet compliance with blood sugar levels in DM patients at the Andalas Public Health Center, Padang City. The research method is descriptive-analytic with a cross-sectional approach, with a total sample of 75 people. The results showed that 78.7% of the respondents have hyperglycemia, 72.0% with non-compliant to their diet limitation, and 68.0% with low self-efficacy. A relationship exists between diet compliance and blood sugar levels in type 2 DM patients. There is a relationship between self-efficacy and blood sugar levels in type 2 diabetes mellitus patients at the Padang Andalas Public Health Center in 2022.
