Application of Health Belief Model for the assessment of COVID-19 preventive behavior and its determinants among students: A structural equation modeling analysis
Authors: Shitu Kegnie , Adugna Asmamaw , Kassie Ayenew , Handebo Simegnew 
Published: March 2022

Background
COVID-19 is a new pandemic that poses a threat to people globally. In Ethiopia, where classrooms are limited, students are at higher risk for COVID-19 unless they take consistent preventative actions. However, there is a lack of evidence in the study area regarding student compliance with COVID-19 preventive behavior (CPB) and its predictors.

Objective
This study aimed to assess CPB and its predictors among students based on the perspective of the Health Belief Model (HBM).

Method and materials
A school-based cross-sectional survey was conducted from November to December 2020 to evaluate the determinants of CPB among high school students using a self-administered structured questionnaire. 370 participants were selected using stratified simple random sampling. Descriptive statistics were used to summarize data, and partial least squares structural equation modeling (PLS-SEM) analyses to evaluate the measurement and structural models proposed by the HBM and to identify associations between HBM variables. A T-value of > 1.96 with 95% CI and a P-value of < 0.05 were used to declare the statistical significance of path coefficients.

Result
A total of 370 students participated with a response rate of 92%. The median (interquartile range) age of the participants (51.9% females) was 18 (2) years. Only 97 (26.2%), 121 (32.7%), and 108 (29.2%) of the students had good practice in keeping physical distance, frequent hand washing, and facemask use respectively. The HBM explained 43% of the variance in CPB. Perceived barrier (β = - 0.15, p < 0.001) and self-efficacy (β = 0.51, p <0.001) were significant predictors of student compliance to CPB. Moreover, the measurement model demonstrated that the instrument had acceptable reliability and validity.

Conclusion and recommendations
COVID-19 prevention practice is quite low among students. HBM demonstrated adequate predictive utility in predicting CPBs among students, where perceived barriers and self-efficacy emerged as significant predictors of CPBs. According to the findings of this study, theory-based behavioral change interventions are urgently required for students to improve their prevention practice. Furthermore, these interventions will be effective if they are designed to remove barriers to CPBs and improve students’ self-efficacy in taking preventive measures.

Background and objectives
Chronic inflammatory airway diseases, including asthma and chronic obstructive pulmonary disease (COPD), are complex syndromes with diverse clinical symptoms due to multiple pathophysiological conditions. In this study, using common and shared risk factors for the exacerbation of asthma and COPD, we sought to clarify the exacerbation-prone phenotypes beyond disease labels, and to specifically investigate the role of the IL4RA gene polymorphism, which is related to type 2 inflammation, in these exacerbation-prone phenotypes.

Methods
The study population comprised patients with asthma (n = 117), asthma-COPD overlap (ACO; n = 37) or COPD (n = 48) and a history of exacerbation within the previous year. Cluster analyses were performed using factors associated with both asthma and COPD exacerbation. The association of the IL4RA gene polymorphism rs8832 with each exacerbation-prone phenotype was evaluated by multinomial logistic analyses using non-asthma non-COPD healthy adults as controls (n = 1,529). In addition, the genetic influence of rs8832 was also examined in asthma patients with allergic rhinitis and no history of exacerbation (n = 130).

Results
Two-step cluster analyses identified five clusters that did not necessarily correspond to the diagnostic disease labels. Cluster 1 was characterized by high eosinophil counts, cluster 2 was characterized by smokers with impaired lung function, cluster 3 was characterized by the presence of gastroesophageal reflux, cluster 4 was characterized by non-allergic females, and cluster 5 was characterized by allergic rhinitis and elevated total immunoglobulin E levels. A significant association with rs8832 was observed for cluster 5 (odds ratio, 3.88 (1.34–11.26), p = 0.013) and also for the type 2 exacerbation-prone phenotypes (clusters 1 and 5: odds ratio, 2.73 (1.45–5.15), p = 1.9 × 10−3).

Discussion
Our results indicated that the clinical heterogeneity of disease exacerbation may reflect the presence of common exacerbation-prone endotypes across asthma and COPD, and may support the use of the treatable traits approach for the prevention of exacerbations in patients with chronic inflammatory airway diseases.

Abstract
Due to the presence of electric fields and piezoelectricity in various living tissues, piezoelectric materials have been incorporated into biomedical applications especially for tissue regeneration. The piezoelectric scaffolds can perfectly mimic the environment of natural tissues. The ability of scaffolds which have been made from piezoelectric materials in promoting cell proliferation and regeneration of damaged tissues has encouraged researchers in biomedical areas to work on various piezoelectric materials for fabricating tissue engineering scaffolds. In this review article, the way that cells of different tissues like cardio, bone, cartilage, bladder, nerve, skin, tendon, and ligament respond to electric fields and the mechanism of tissue regeneration with the help of piezoelectric effect will be discussed. Furthermore, all of the piezoelectric materials are not suitable for biomedical applications even if they have high piezoelectricity since other properties such as biocompatibility are vital. Seen in this light, the proper piezoelectric materials which are approved for biomedical applications are mentioned. Totally, the present review introduces the recent materials and technologies that have been used for tissue engineering besides the role of electric fields in living tissues.

Published: March 2022

Abstract
The mixing performance in a miniature conical counter-rotating twin-screw extruder was investigated by means of experimental technique and computational fluid dynamics (CFD) simulation. An on-line experimental device based on the fluorescence detection was built to study the residence time distribution (RTD). Polypropylene was selected as the flow material and the blend of Polypropylene and anthracene was used as the tracer. This on-line detection device has good reproducibility. The hydrodynamics in the extruder was simulated by the finite element method (FEM) combined with the mesh superposition technique (MST). The particle tracking technique was carried out to evaluate the RTD and mixing efficiency. The effect of screw speed and feed rate on the hydrodynamics and mixing performance was investigated. The velocity magnitude and local shear rate tend to become smaller from inlet to outlet due to the decreasing diameters of screws. The mean length of stretch increases exponentially from inlet to outlet and the mean value of time averaged mixing efficiency remains positive along the axial direction.

Investigation of measurement data of low-coherence interferometry at tilted surfaces in the 3D spatial frequency domain

Published: March 2022

Abstract
The 3D transfer characteristics of interference microscopes and their effect on the interference signals occurring at surface slopes are studied. The interference image stacks acquired during a depth scan are 3D Fourier transformed. This allows a comprehensive frequency domain analysis of the interferograms. The double foil model introduced in a previous publication enables the interpretation of the signal spectra and the underlying transfer behavior of the interferometer using the concept of the Ewald sphere, which is limited by the numerical aperture (NA) of the imaging system. Analysis in the 3D spatial frequency domain directly discloses that the lateral dimensions of the transfer function depend on the axial spatial frequency. In this contribution we investigate measuring objects produced by Nanoimprint-Lithography. The corresponding signal spectra bear information that can be utilized to optimize the subsequent signal processing algorithms. These include envelope and phase evaluation procedures of the interference signals. A narrow bandpass filter is used to actively select certain frequency components in order to improve the robustness of the estimation of the envelope position. Although the shape and width of the envelope are affected, this procedure increases the reliability of the evaluation process and improves the accuracy of the measured topography especially at steeper surface slopes.
Lithium ion transport in micro- and nanocrystalline lithium sulphide Li2S

Published: March 2022

Abstract
Ion dynamics in binary Li-bearing compounds such as LiF, Li2O and Li2S is rather poor. These compounds do, however, form as decomposition products at the interface between the electrolyte and the electrode materials in lithium-based batteries. They are expected to severely influence the charge transport across this electrode-electrolyte interface and, thus, the overall performance of such systems. Yet, ion dynamics in the nanostructured forms of these binary compounds has scarcely been investigated. Here, we prepared bulk nanostructured Li2S through high-energy ball milling and studied its temperature-dependent ionic conductivity by means of broadband impedance spectroscopy. It turned out that, compared to the unmilled form, Li+ ion conductivity in ball-milled Li2S increased by approximately 3 orders or magnitude. This striking increase is accompanied by a decrease of the average activation energy from ca. 0.9 eV to approximately 0.7 eV. Structural disorder, stress and local distortions are assumed to be responsible for this clear change in macroscopic transport parameters. Fast ion dynamics in or near the interfacial space charge zones might contribute to enhanced dynamics, too. We conclude that Li ion transport in interfacial Li2S, if present in a disordered nanostructured form in lithium-ion batteries, is much faster than originally thought for its ordered counterpart.

Authors: Pato Enrique 
Published: March 2022

AbstractThis work offers an in-depth description of the main morphosyntactic (and lexical) features found in present Salvadoran Spanish, a lesser-known Central American variety. Text corpora and sociolinguistic surveys help us to provide an updated grammatical overview, which takes into account most categories: nouns and adjectives, pronouns, verbs, adverbs, prepositions and locutions, and illustrates with examples taken both from formal and informal settings. By comparing these features with previous grammatical descriptions, this study helps in identifying some common American features —such as the use ofhasta (que)anduna mi amiga— as well as some specific patterns —such as the prominence of -adoand -ososuffixes,utualitoadverb,algotropronoun and old expletivelo— in present-day Salvadoran Spanish, some of which remain to be incorporated in the Academy grammar (simasitoadverb,al no más+ infinitive locution).

Privát családi fényképezés a 19–20. század fordulóján
Authors: Sidó Anna 
Published: March 2022

Tanulmányomban a 19–20. század fordulóján Szabadkán élt Brenner József fotós tevékenységén keresztül tárom fel az amatőr fényképezés, mint szabadidős tevékenység, kibontakozásának történetét. Vizsgálatom fókuszában Brenner tevékenysége és családi fényképei állnak, mely tematika alapvetően határozta meg az amatőr fényképészet szélesebb körben való elterjedésének kezdeti korszakát. A családfő, Id. Brenner József nem csupán az író, Csáth Géza (Brenner József) apjaként ismert, hanem Szabadka egyik első jegyzett amatőr fotósa is volt, aki 1898 tavaszától az 1930-as évekig saját fényképezőgépével örökítette meg a családtagokat és a hozzájuk kötődő eseményeket. A privát vagy családi fényképezés behatóbb megértése érdekében a dolgozat elején a legmeghatározóbb fotóelméleti munkák segítségével szeretném körvonalazni a családi, illetve a privát fotó fogalmi kereteit, melyet végig referenciaként használok. A tanulmány során célom, hogy részletesen feltárjam id. Brenner fényképezési tevékenységének indulását, figyelembevéve annak kulturális előképeit, technikai és szaktudásbeli feltételeit. Ennek kapcsán két meghatározó problémára keresem a választ: milyen társadalmi, szellemi és technikai körülmények között kezdődött egy amatőr fotós tevékenység a századfordulón, valamint milyen általános ikonográfiai elemei vannak a családi fotózásnak, ami érvényes lehet mind Brenner képeire is.
A tanulmányban tehát e kulturális gyakorlatnak a kezdeti időszakára szeretnék rávilágítani, arra a korra, amikor ennek a műfajnak rögzültek a vizuális kódjai, kellékei, jelentése és kulturális szokásrendszere. Mindezt pedig bemutatva egy esettanulmányon, azaz id. Brenner példáján és fotóin keresztül. A vizsgált téma összetettsége módszertanában és szempontrendszerében egyszerre több diszciplínát is érint, így egyebek mellett a fotótörténet, a vizuális antropológia, a kommunikáció, illetve a kultúrtörténet területeit.

Published: March 2022

Abstract
This study presents a laboratory testing program consisting of incremental loading, constant rate of strain, and specially designed, pseudo K0-triaxial tests to provide insight into the in situ stress state of residual soil masses and the ability to reproduce those in a laboratory environment. The testing program was conducted at two different sites derived from an igneous-metamorphic basement located in the northern Andes and included in situ measurements of earth pressure coefficients, K0, and shear wave velocities, Vs, to validate those measured in the laboratory. The laboratory tests and procedures along with the direct comparison with field measurements are also used to evaluate disturbance effects on compressibility responses. The results indicate that K0 recompression to the overburden stress is adequate for reproducing the in situ stress state of the tested residual soils. Similar to sedimentary soils, laboratory testing of large residual soil specimens results in less disturbance.
