Authors: Topcu Deniz İlhan , Bayraktar Nilüfer 
Published: July 2022

Abstract

Objectives
Automated machine learning (AutoML) tools can help clinical laboratory professionals to develop machine learning models. The objective of this study was to develop a novel formula for the estimation of urine osmolality using an AutoML tool and to determine the efficiency of AutoML tools in a clinical laboratory setting.

Methods
Three hundred routine urinalysis samples were used for reference osmolality and urine clinical chemistry analysis. The H2O AutoML engine completed the machine learning development steps with minimum human intervention. Four feature groups were created, which include different urinalysis measurements according to the Boruta feature selection algorithm. Method comparison statistics including Spearman’s correlation, Passing–Bablok regression analysis were performed, and Bland Altman plots were created to compare model predictions with the reference method. The minimum allowable bias (24.17%) from biological variation data was used as the limit of agreement.

Results
The AutoML engine developed a total of 183 ML models. Conductivity and specific gravity had the highest variable importance. Models that include conductivity, specific gravity, and other urinalysis parameters had the highest R2 (0.70–0.83), and 70–84% of results were within the limit of agreement.

Conclusions
Combining urinary conductivity with other urinalysis parameters using validated machine learning models can yield a promising surrogate. Additionally, AutoML tools facilitate the machine learning development cycle and should be considered for developing ML models in clinical laboratories.

Abstract

Objectives
The purpose of this study was to determine the onset of fetal movements’ perception and to identify parameters that affect this timing.

Methods
This was a prospective cohort study including singleton pregnancies that attended routine prenatal care, in a tertiary care center, in northern Greece, between January 2020 and July 2021. We collected data on medical and obstetric history, and invited women to record the time that they perceived the fetal movements for the first time, that being the primary outcome of the study. Furthermore, we studied the associations between this timing and several obstetric and sociodemographic parameters.

Results
In total, 2,009 women participated in the study. The mean gestational age at first perception of fetal movements was 19 weeks (±1.5). This ranged from as early as 14+0–14+6 weeks (0.1%) to 24+0–24+6 weeks (0.1%). The majority of women (73.3%) reported initial perception of fetal movements between 18+0 and 20+6 weeks. Following multivariate logistic regression analysis, we found that nulliparity (OR: 2.607; 95% CI: 1.876–3.622; p<0.001), anterior placental position (OR: 1.918; 95% CI: 1.575–2.336; p<0.001), increasing body mass index (OR: 1.063; 95% CI: 1.040–1.088; p=0.001) and advancing maternal age (OR: 1.062; 95% CI: 1.040–1.084; p<0.001) were associated with a delayed perception of fetal movements. Multiparous women reported the onset of fetal movements almost one week earlier on average (18.6±1.4 weeks) compared to nulliparous (19.4±1.4 weeks; MD: 0.843; 95% CI: 0.718–0.968; p<0.001).

Conclusions
The onset of maternal perception of fetal movements is around 19 weeks and this timing may be delayed by higher maternal age, higher body mass index, nulliparity and anterior placental position.

Authors: Kapoor Mamta , Majumder Arunava , Joshi Varun 
Published: July 2022

Abstract
Obtaining the numerical approximation of fractional partial differential equations (PDEs) is a cumbersome task. Therefore, more researchers regarding approximated-analytical solutions of such complex-natured fractional PDEs (FPDEs) are required. In this article, analytical-approximated solutions of the fractional-order coupled Burgers’ equation are provided in one-, two-, and three-dimensions. The proposed technique is named as Iterative Shehu Transform Method (ISTM). The simplicity and accurateness of the method are affirmed through five examples. Graphical representation and tabular discussion are provided to compare the exact and approximated results. The robustness of the proposed regime is also validated by error analysis. In the present work, approximated and exact solutions are compared to verify the validity of the proposed scheme. Error analysis is also provided through which the efficiency of the proposed scheme can be assured. Obtained errors are lesser than the compared results.

Published: July 2022

Abstract
The creep of face-slab concrete in a rockfill dam is critical for determining the restrained stress and cracking resistance of the concrete at an early age. In this article, the mix proportion of the face-slab concrete for a rockfill dam under construction without any cracking resistance additive was taken as the reference concrete (called JC) mix proportion. The carbon nanotubes (CNTs) and magnesium oxide expansion agent (MEA) were incorporated into JC to prepare face-slab concretes called NC and PC, respectively. The temperature–stress tests under temperature matching curing (TMC) and constant temperature curing (CTC) modes were conducted on these three kinds of concretes to investigate the effects of CNTs and MEA on the early-age creep properties of the face-slab concrete under variable stress conditions. The results showed that the creep performance of NC concrete under CTC mode was lower than that under TMC mode. Combined with mercury intrusion porosimetry test results, the mechanism of the effect of CNTs and MEA on creep was analyzed. The results showed that the temperature change may lead to the CNTs debonding from the cementitious matrix or matrix cracking for the NC concrete. The incorporation of CNTs can increase the early-age creep and improve the cracking resistance of concrete.

Published: July 2022

Abstract
For the first time, highly conductive thickly layered two-dimensional titanium carbide (MXene) was applied as a new coating agent for electromembrane-surrounded solid-phase microextraction (SPME) of triadimenol and iprodione as two model analytes. Preparation of the desired coated electrode was carried out using electrophoretic deposition of MXene on the surface of platinum electrode. Characterization of the prepared coated electrode was conducted using scanning electron microscopy and energy-dispersive X-ray spectroscopy. The coated electrode was located inside a hollow fiber membrane impregnated by 2-nitrophenyl octyl ether as the supported liquid membrane (SLM), while an aqueous solution was injected inside the hollow fiber lumen. Separation and quantification of the analytes were carried out using a gas chromatography instrument equipped with mass spectrometric detection. The effective parameters of the microextraction procedure comprising pHs of sample solution and the acceptor phase, composition of the SLM, extraction time, and the applied voltage were optimized using one-variable at-a-time method. Under the optimal conditions, the calibration curves of the analytes were linear (R
2 > 0.9973) in the range of 0.3–250.0 and 0.5–250.0 ng mL−1 for triadimenol and iprodione, respectively. The limit of detections was determined to be 0.10 and 0.15 ng mL−1 for triadimenol and iprodione, respectively. Repeatability and reproducibility of the method were evaluated by the calculation of intra-day and inter-day relative standard deviations (%). The applicability of the method was evaluated by quantitative analysis of the model analytes in environmental water samples. Relative recoveries in the range of 87.31–102.7% confirmed that the prepared coated electrode can be considered a reliable option in electromembrane-surrounded SPME techniques.

Abstract
Mount Semeru is one of the most active volcanoes in Indonesia and the highest mountain in Java Island. Although the island is prone to volcanic eruptions, it is densely populated and also home to several farmers. The aim of this study is to analyze the strategies for overcoming farmers’ lives in Mount Semeru. This study involves 150 farmers who were randomly selected from terrains located at altitudes between 6 and 10 km in Mount Semeru. This study shows that farmers benefit significantly from the fertile lands resulting from volcanic eruptions. And they are highly motivated to engage in mitigation activities to reduce the impacts of eruption; therefore, they tend to participate in mitigation education or programs organized by government or private institutions. Support with the information and financial access regarding any mitigation strategies can help farmers a lot. Coordination among stakeholders to support mitigation strategies is necessary because all the parties are equally responsible for alleviating the impacts of volcanic eruptions. Any strategies for overcoming farmers’ lives in volcano areas also can be supported by community resilience.
A Blocked-Out Capital from Berenike (Egyptian Red Sea Coast)
Authors: Popławski Szymon , Kraśniewska Urszula , Mi Filippo 
Published: July 2022

Abstract
The article examines a blocked-out capital discovered in Berenike on the Egyptian coast of the Red Sea. The artefact was reused in a Late Antique installation just outside the courtyard wall of the main city sanctuary, the Isis Temple. Its distinctive, highly simplified form is typical of Ptolemaic influence in the area. This article places the fragment in its archaeological context, accompanied by a detailed architectural description and analysis of the phenomena of blocked-out capitals. The authors demonstrate that the capital under discussion does not represent an unfinished stonework, but rather an intentional stylization. Its simplification is most likely inspired by the form of Corinthian capital that was common in Egypt between the second and third century AD. The discovery of this capital implies that there were buildings with classical architectural traits in Berenike, a theory that has previously not been supported by the excavated remains.

Published: July 2022

Abstract
The reaction of an orthoamide derivative of phenylpropiolic acid (22a) with primary and secondary amides gives rise to the formation of a wide spectrum of reaction products. The reaction of 22a with formamide delivers a N-carbamoyl-cinnamic acid amidine, wheras the analogous reaction with methylene-diformamide leads to a ketenaminal, which is substituted in β-position by a N-formylimino group. From the orthoamide 22a and phthalimide a phthalic acid amide amidine is obtained. In contrast the reaction of diformamide with 22a affords a β-imino enamine. 2,6-Diaminopyridines can be obtained from 22a with acetamide, propionamide and butyramide in low yields. The pyridines are characterized as perchlorates. From 22a and benzamide a 4-amino-2,6-diphenylpyrimidine is obtained in low yield. In the reaction of the closely related orthoamide derivative of 4-Cl-phenylpropiolic acid 22b with benzamide are isolated as a further products two pyrimidine derivatives. A pyrimidinone and a vinylogous thiourea can be obtained from 22a and urea and thiourea, respectively.

Authors: Lin Gan , Lin Huirong , Yuan Zhen , Liu Gang 
Published: July 2022

Abstract
Advances in in vivo iron-based coordination assembly have enabled the simultaneous detection and treatment of iron-overload disorders. Specific interactions between local FeIII and organic ligands (e.g., indocyanine green and lecithin) facilitate magnetic resonance imaging with enhanced sensitivity and photoacoustic imaging with high contrast, thus overcoming the longstanding limitations of traditional iron quantification approaches. Moreover, enhanced iron depletion can also be achieved in murine genetic models of iron-overload disorders. These advances provide great promise in interdisciplinary leveraging of biology, medicine and materials science to design nanomedicines for addressing unmet clinical needs.

Building Stones of Resilience of Vulnerable Older Persons
Authors: Witte Jasper De , Regenmortel Tine Van 
Published: July 2022

Introduction: Vulnerable older persons need sufficient resilience to deal with (age-related) adversities and safeguard their quality of life. In this study, we investigate which sources of strength vulnerable older persons use to deal adversities.

Methods: This qualitative study is based on fifteen narratives of community-dwelling vulnerable older persons in Belgium, who were selected through a ‘purposive sampling’ strategy.

Results: Vulnerable older persons use various interrelated sources of strength situated on the individual, interactional, and contextual domains. On the individual domain, important sources of strength are having an optimistic life view and accepting the own vulnerabilities. On the interactional domain positive social relations, ‘the power of giving’ and social participation are sources of strength that benefit the quality of life of older persons, and on the contextual domain various welfare benefits are essential.

Conclusion: It is crucial to stimulate those sources of strength, for example by removing contextual barriers that impede social participation. The results can guide empowering interventions that aim to reinforce the sources of strength of vulnerable older persons, which will positively affect their resilience and general well-being.

Authors: Mokhtari Akram , Nabilou Bahram , Aghlmand Siamak , Yusefzadeh Hasan 
Published: July 2022

Background: The importance of paying attention to improving productivity in different health system departments has become increasingly evident. This is due to increased costs of health care goods and services, limited resources and production facilities. This study aims to measure the productivity of hospitals' Medical Records Departments (MRD) affiliated with Urmia University of Medical Sciences to provide a comprehensive analysis of their performance.
Methods: In this study, total productivity and total factor productivity changes of medical record departments in hospitals affiliated with Urmia University of Medical Sciences were calculated. This was conducted through Kendrick-Creamer and Malmquist indexes in 2016-2020, and has examined the trend of each one of them. Input variables included the number of personnel and equipment. Output variables encompassed the number of outpatient and inpatient medical records prepared for patients, responses to letters, and patients referred to the studied MRD. After estimating the production function, the elasticity of production factors and the return to the scale of medical record departments were calculated.Total productivity changes and production function were estimated via Deap2,1 and Frontier4,1 softwares by applying input minimization and variable returns to scale assumptions.
Results: The results of the Malmquist index indicated that the average total productivity changes of medical records departments of hospitals during the study period were equal to 1,096. This is greater than one; therefore, it can be concluded that productivity has decreased by about 9.600 % during the study period. Changes in technological efficiency have had the greatest impact on reducing productivity, to other factors. In addition, the results of Kendrick-Creamer index during the years under review demonstrated that the average total productivity of production factors obtained, was equal to 18725.530 services.
Conclusion: There is decreased productivity due to technological changes in the studied departments. This is because of the lack of sufficient knowledge of the medical records department staff in the use of technology and equipment for providing efficient services . Holding training courses for the appropriate use of technology by personnel can be useful in this regard.

This research about sustainable development and its relationship with corporate culture was developed in a medium-sized city in the south of Mexico, Veracruz. The objective of this work is to find a comprehensive-interpretative explanation of the phenomenon studied to evidence the relationships that are established between the administrative discourse (management), the organizational culture and some elements of sustainable development. This research was developed under a qualitative modality and were used as techniques for the collection of information, individual and semi-structured interviews that were recorded and later transcribed for analysis. It presents the case of a school where despite de efforts made by the organizational actors (director, students, secretary, professors and parents) to make their school a sustainable organization, fundamental controversies are observed between what was planned and executed (administration), with he values, believes and the meanings that the actors give to the care of the resources inside the institution ( organizational culture) in terms of inhibit the waste of the electric energy, the water, and the non-assumption of the ecological habits to develop and maintain the green areas of the school.
