Optimization of axial load carrying capacity of CFST stub columns
Authors: Çakıroğlu Celal , Bekdaş Gebrail
Published: March 2022

Concrete filled steel tubular (CFST) columns are widely used due to their enhanced mechanical properties. The interaction between the concrete core and the steel casing increases structural stability and magnifies the compressive strength of concrete. Besides the structural performance, in alignment with the commitment of the concrete industry to reduce its environmental impact, lowering the carbon emissions caused by the production of concrete structures is gaining importance in recent years. The current paper gives an overview of the equations available in the literature that predict the axial load carrying capacity of rectangular CFST columns. A modified version of the Jaya metaheuristic algorithm is being proposed and the outcome of this algorithm is being presented. The algorithm is used in order to maximize the axial load-carrying capacity of a stub column. As an optimization constraint the CO2 emission associated with the production of the CFST column is being kept below a predefined level throughout the optimization process. The optimization process as well as the cross-sectional dimensions associated with the optimum solution are presented.
Optimum design of a vaulted roof steel structure using grey wolf and backtracking search optimization algorithms through application programming interface
Authors: Tunca Osman
Published: March 2022

In present study, structural formation identification of a vaulted roof steel structure is taken as optimization problem. The cost of a steel structure is directly related to the weight of the structure. Weight minimization of the vaulted roof steel structure is considered as objective function of the design problem. The design problem is intended to be as realistic as possible. Wind loads and snow loads are calculated in direction of TS EN 1991-1-4 and TS EN1991-1-3practice code specifications, respectively. And dead loads reobtained in terms of gravity. The structural design constraints of the optimization problem are determined according to American Institute of Steel Construction-Allowable Stress Design (AISC-ASD). In the design, W-shaped steel profile sections to be selected for assigning to the structural elements are considered as discrete design variables. Grey Wolf Optimizer (GWO) and Backtracking Search Optimization (BSO) algorithms that are relatively recent metaheuristic algorithms are utilized as optimizer tools to obtain the minimum weighted structural design. The vaulted roof steel structure is initially modeled in a finite element packaged software (ANSYS Workbench v18.1). Then, using the application programming interface of the software, integration of finite element model with GWO and BSO optimization algorithms encoded in Microsoft Visual Basic for Application (MS VBA v7) programming language is provided. Thus, the performances of two new generation optimization algorithms in design optimization of a vaulted roof steel structure are compared and the benefits of the application programming interface are demonstrated.
Characterization of Superalloys by Artificial Neural Network Method
Authors: Görgün Emre
Published: March 2022

In this study, the use of artificial neural networks in the classification of a superalloys whose chemical analysis is performed
in the quality process is investigated. In general, chemical spectro analysis method alone is not sufficient to determine which class a steel
belongs to. In addition to the chemical analysis method, tests such as tensile test, hardness test or notch impact test are applied. The tests
performed in addition to the chemical analysis both take time and destroy the material. The fact that an algorithm that classifies steel
only according to the results of chemical analysis is not used has made destructive tests mandatory. Artificial neural networks (ANNs),
usually simply called neural networks (NNs), are computing systems inspired by the biological neural networks that constitute animal
brains. An ANN is based on a collection of connected units or nodes called artificial neurons, which loosely model the neurons in a
biological brain. Each connection, like the synapses in a biological brain, can transmit a signal to other neurons. In our study, a total of
34 superalloy materials belonging to 6 different classes were used. Chemical composition values were determined for each superalloy
sample. The appropriate artificial neural network model was determined according to the chemical composition values. A model that
can predict superalloy material based on chemical composition value has been created. Weka 3.9.5 package program was used to create
the artificial neural network model. The high success rate of the prediction model gave hope for the determination of the material class
only with the chemical analysis method.
Algebraic function based Banach space valued ordinary and fractional neural network approximations
Authors: Anastassiou George A.
Published: March 2022

Here we research the univariate quantitative approximation, ordinary and fractional, of Banach space valued continuous
functions on a compact interval or all the real line by quasi-interpolation Banach space valued neural network operators. These
approximations are derived by establishing Jackson type inequalities involving the modulus of continuity of the engaged function or
its Banach space valued high order derivative of fractional derivatives. Our operators are defined by using a density function generated
by an algebraic sigmoid function. The approximations are pointwise and of the uniform norm. The related Banach space valued
feed-forward neural networks are with one hidden layer.

Authors: Katzarov Ivaylo Hristov , Drenchev Ljudmil Borisov
Published: March 2022

We have developed a self-consistent model for predicting
velocity of 1/2[111] screw dislocation in binary iron--carbon alloys gliding by a high-temperature Peierls mechanism.
The methodology of modelling includes: (i) Kinetic Monte-Carlo (kMC) simulation of carbon segregation in dislocation core and determination the total carbon occupancy of the core binding sites;
(ii) Determination of kink-pair formation enthalpy of
a screw dislocation in iron---carbon alloy;
(iii) KMC simulation of carbon drag and determination of
maximal dislocation velocity at which the atmosphere
of carbon atoms can follow a moving screw dislocation;
(iv) Self consistent calculation of average velocity of
screw dislocation in binary iron--carbon alloys gliding by a
high-temperature kink-pair mechanism under constant strain rate.
We conduct a quantitative analysis of the conditions of stress and temperature at which screw dislocation glide in iron--carbon alloy is accomplished by a high-temperature kink-pair mechanism.
We estimate the dislocation's velocity at which
screw dislocation brakes away from the carbon cloud
and thermally-activated smooth dislocation propagation is interrupted by sporadic bursts controlled by athermal dislocation activity.
Optimal Design of an Interior Permanent Magnet Synchronous Motor with Cobalt Iron Core
Authors: Bhagubai Pedro P. C. , Bucho Luís F.D. , Fernandes João F. P. , da Costa Branco Paulo J.
Published: March 2022

The use of cobalt-iron (VaCoFe) core is investigated as an alternative to silicon-iron (FeSi) on the design of interior permanent magnet synchronous motors (IPMSM). A spoke-type IPMSM geometry is optimized considering FeSi and VaCoFe cores for a torque range up to 40 N.m, providing a general comparative analysis between materials, considering the application of a 4-motor competition vehicle’s powertrain. A genetic optimization algorithm is applied over a hybrid analytical/finite-element model of the motor to provide sufficiently accurate electromagnetic and thermal results within a feasible time. VaCoFe can result in an estimated increase of up to 5 % in efficiency for the same torque, or up to 64 % torque increase for the same efficiency level. After optimization, and using a detailed time-dependent model, a potential 3.2 % increase in efficiency, a core weight reduction of 4.1 %, and a decrease of 9.6 % in the motor’s core volume was found for the VaCoFe at 20 Nm. In addition, for the same motor volume, the VaCoFe allows an increase of 51.9 % of torque with an increase of 1.1 % of efficiency, when compared with FeSi.
Novel Centroid Method for Robust Evaluation of Return Time of Reflected Waves in the Systemic Arterial Network
Authors: Kondiboyina Avinash , Smolich Joseph J , Cheung Michael MH , Mynard Jonathan P
Published: March 2022

Arterial ageing is thought to cause a diastolic-to-systolic shift in the return time (RT) of backward waves to central arteries. However, current methods of estimating RT—inflection point, zero crossing, and foot methods—depend on a single waveform feature and produce systolic RT throughout life. We propose a novel centroid method that accounts for the entire backward pressure waveform and develop a ground truth RT (GTRT), which can be used in computational models to test the accuracy of RT estimation methods. Linear wave tracking was implemented in a one-dimensional systemic arterial tree model and GTRT was calculated as the amplitude-weighted mean RT of backward waves at the ascending aorta. Using a virtual cohort of 1200 patients, the centroid RT was closest to GTRT compared to the zero crossing, inflection point, and foot methods; mean differences (limits of agreement) were -8 (-47,30), vs -42 (-136,52), -78 (-305,149), and -197 (-379,-15) ms, respectively. The sensitivity of the methods to changes in RT was also assessed in ten sheep. A balloon catheter in the descending thoracic aorta was used to generate a backward-running pulse that arrived at the ascending aorta at different times during diastole or systole, allowing the “bulk” RT of the backward-running wave ensemble to be manipulated. Only the centroid method was sensitive to both diastolic and systolic changes in RT. We conclude that the accuracy and robustness of the centroid method make it most suitable for evaluating the diastolic-to-systolic shift in RT of backward waves with ageing.

Investigating the Effect of Consumers’ Knowledge on their Acceptance of Functional Foods: A Systematic Review and Meta-Analysis
Authors: Baker Mathew T. , Lu Peng , Parrella Jean A. , Leggette Holli R.
Published: March 2022

Inconsistent results published in previous studies make it difficult to determine the precise effect of consumer knowledge on their acceptance of functional foods, which were developed to improve consumers’ health status by providing adequate nutrition. We conducted a systematic review and meta-analysis by identifying and collecting relevant literature from three databases. Of the 1050 studies we reviewed, we included 40 in the systematic review and 18 in meta-analysis. Based on the focus of each included study, we operationally defined knowledge as knowledge of the functional food concept, nutritional-related knowledge, and knowledge of specific functional products. Results from the systematic review indicate that most participants from the included studies had a low level of knowledge, especially nutrition-related knowledge associated with consuming functional foods, and they were generally not familiar with the concept of functional foods. It is possible that participants’ level of knowledge was influenced by their demographic characteristics (e.g., age, gender, educational level, marital status, nationality). Results from the meta-analysis generated a summary effect size (r = 0.14, 95% CI [0.05; 0.23]), measured by the correlation coefficient r, which indicates that a small positive relationship exists between consumers’ level of functional foods knowledge and their acceptance of functional foods.

Based on the data of A-share listed companies in Shanghai and Shenzhen of China from 2011 to 2018 and the digital inclusive finance index of Peking University (2011-2018), this paper empirically tests the impact of digital finance development on corporate social responsibility in various provinces of China and its impact mechanism. The results show that: (1) the development of digital finance helps to promote the fulfillment of corporate social responsibility; (2) the influence mechanism of the development of digital finance to promote the fulfillment of corporate social responsibility lies in that it reduces the cost of debt financing and leads to the improvement of corporate social responsibility.(3) Further research shows that the positive relationship between digital finance and corporate social responsibility is more significant in private enterprises. At the same time, the impact is more significant in areas with poor market environment. The above research shows that the development of digital finance has a significant positive effect, which will improve the level of corporate social responsibility.

Published: March 2022

Eating and drinking difficulties are common in dementia, but little is known about the experiences of ethnic minority groups managing these difficulties at home. We undertook qualitative semi-structured interviews, exploring the meaning of food, the impact of dementia on eating and drinking and carers’ experiences of support. Interviews were audio-recorded and transcribed verbatim. We interviewed 17 carers and people with dementia from ethnic minority backgrounds, using reflexive thematic analysis to analyse data. Food/drink had strong links to identity, culture and emotions. Providing culturally familiar foods, celebrating traditional festivals and supporting previous food-related roles promoted reminiscence, which encouraged people with dementia to eat and drink, as did social interactions. However, these strategies sometimes led to distress in those with more advanced dementia. Food choices were also influenced by carer strain, generational differences and the impact of health conditions. Despite a strong sense of duty to care for relatives at home, there was low awareness of community support services. Carers expressed a need for culturally tailored support for managing dementia-related eating and drinking difficulties at home. Healthcare professionals must provide contextually relevant advice to carers, being mindful of how cultural backgrounds can affect dietary choices.
COVID-19 Test Frequency Versus Test Sensitivity in Disrupting SARS-CoV-2 Transmission: A Review of Statistical Modeling Simulations
Authors: Rogers Justin , Jackson Laurel , Buss Adam , Gawel Susan
Published: March 2022

Objectives: This paper presents a statistical review of modelling simulations for frequency and sensitivity of COVID-19 testing paradigms. Methods: We performed a review of preprints and published articles on PubMed from January 1, 2020 – March 1, 2021 using the search terms “COVID screening testing”, “COVID testing frequency”, “COVID testing frequency screening” and “SARS-CoV-2 testing frequency”.Results: Several authors’ conclusions support the claim that test frequency and test sensitivity both play a role in reducing SARS-CoV-2 transmission. We highlight the interplay between frequency of testing, test sensitivity and the speed at which test results are available in our review. Conclusions: Evidence suggests that sensitivity and frequency of testing both play a part in decreasing transmission of disease. We conclude that, overall, test sensitivity plays less of a role in reducing disease transmission in a population compared to the frequency of testing and how quickly test results are available.
Monte Carlo Simulations of the Metal-Directed Self-Assembly of Y-Shaped Positional Isomers
Authors: Nieckarz Karolina , Nieckarz Damian
Published: March 2022

The rational fabrication of low-dimensional materials with a well-defined topology and functions is an incredibly important aspect of nanotechnology. In particular, the on-surface synthesis (OSS) methods based on the bottom-up approach enable facile construction of sophisticated molecular architectures unattainable by traditional methods of wet chemistry. Among such supramolecular constructs especially interesting are surface-supported metal-organic networks (SMONs), composed of low-coordinated metal atoms and π-aromatic bridging linkers differing in size, shape and functionalization scheme. In this work, the lattice Monte Carlo (MC) simulation technique was used to extract the chemical information encoded in a family of Y-shaped positional isomers coadsorbed with trivalent metal atoms on a flat metallic surface with (111) geometry. For this purpose the investigated tritopic molecules/metal atoms were carefully mapped on a triangular lattice as interconnected/isolated segments with appropriatelly embedded anisotropic interactions. Depending on the intramolecular distribution of active centers (functional groups) within the simulated molecular bricks, we observed the metal-directed self-assembly of two-dimensional (2D) openwork patterns, aperiodic mosaics and metal-organic ladders. The obtained theoretical findings could be especially relevant for the scanning tunneling microscopy (STM) experimentalists interested in a surface-assisted construction of complex nanomaterials stabilized by directional coordination bonds.
The Role of Albumin-Globulin Ratio on Predicting Postoperative Pancreatic Fistula in Pancreaticoduodenectomy Patients
Authors: Ciftci Ahmet Burak , Yemez Kursat , Eraslan Huseyin
Published: March 2022

Background and aim: The albumin-globulin ratio (AGR) is one of the indicators of inflammation and immunity and it has a prognostic significance in many malignant diseases. Previous studies have shown the relationship between inflammatory mediators and POPF. This study aimed to evaluate the relation of AGR, which is a relatively new indicator, with postoperative pancreatic fistula (POPF). Methods: Pancreaticoduodenectomy (PD) patients between 2017 and 2020 were retrospectively analyzed and divided into two groups as those with and without clinically relevant POPF (CR-POPF). They were compared in terms of preoperative-postoperative AGR and clinicodemographic characteristics. AGR was calculated as Albumin / (Total protein-albumin) and the cutoff point for AGR was determined according to Youden’s index. Results: CR-POPF developed in 21% of 121 patients who underwent PD. There was no difference between the groups in terms of age, gender, comorbid disease status, pancreatic duct width, and anastomosis technique. Preoperative and postoperative day-3 (POD3) albumin levels and AGR were found to be significantly lower in the CR-POPF group. Multivariate analysis showed that AGR and pancreatic tissue stiffness are independent risk factors for the development of POPF. Conclusions: Low AGR is an independent risk factor for the development of CR-POPF. To reduce the incidence of POPF, this ratio should be tried to be kept at an optimal level.

Published: March 2022

In certain plasma physics problems it is very important to take into account nonequilibrium of the radiation field. Primarily it concerns laser and pinch plasmas characterized by stiff density and temperature gradients. In this paper, a method is presented for approximate accounting for the nonequilibrium of the radiation field in plasmas, which is based on the approximation of the real radiation field by a parameterized Planckian function with subsequent interpolation of plasma properties on a certain tabulated basis. A comparison with several other approximate methods for taking into account the plasma nonequilibrium showed that the proposed method has promising potential.

Published: March 2022

Pekanbaru City has developed quite rapidly. Therefore, local governments are aware of the
high demand for multi-story building construction, so that buildings built with more than two floors
are required to conduct a land subsidence test. The load of a structure will be transmitted by the
foundation to the ground, where the soil is expected to be able to support the load. The soil subsidence
test is obtained from the sondir test data or also called the Dutch Cone Penetration Test (DCPT)
which is used to determine the profile into the soil continuously with the value of cone tip resistance
and blanket resistance (Wafi et al., 2013).The purpose of this study is to analyze the calculation of
the settlement of a single pile foundation based on the foundation bearing capacity data from the
sondir data obtained from the Riau University Laboratory using the elastic settlement method. The
research stages carried out are reviewing theories related to piles, then collecting data including
data on the carrying capacity of the foundation and sondir data. The final stage is conducting
calculation analysis. The results of this study obtained a map of the elastic settlement of the pile
foundation at a depth of 6 meters, 12 meters and 18 meters

Authors: Álvarez Velasco Carla Morena
Published: March 2022

Este artículo describe la influencia de Organizaciones No Gubernamentales de América Latina, en la creación de normas internacionales y en la promoción de normas nacionales orientadas a controlar la proliferación de armas de fuego y la reducción de la violencia armada. El objetivo es, por una parte, visibilizar el papel de estas organizaciones en la promoción de medidas para mitigar los efectos negativos derivados de la proliferación de armas de fuego; y por otra, mostrar sus límites discursivos y de acción, en esta misma labor. Para cumplir con este objetivo, se recurrió al análisis del discurso de más de 50 ONG, integrantes de la antigua Coalición Latinoamericana contra la Violencia Armada.
EL BULLYING (ACOSO ESCOLAR): FACTOR CRIMINÓGENO Y DETONANTE EN EL ORIGEN DE LOS ADOLESCENTES INFRACTORES DE CIUDAD JUÁREZ CHIHUAHUA
Authors: Herrera Hernández Adán
Published: March 2022

La presente investigación se plantea desde un enfoque criminológico, estudiando el bullying (acoso escolar) como tema de estudio dentro de la nueva criminología. Se trata de una investigación documental, de campo exploratoria, cualitativa y transversal, ya que se basó en hechos y conductas predelictivas y delictivas de una muestra de sesenta de adolescentes infractores recluidos en la Escuela de Mejoramiento Social para Menores en Ciudad Juárez, Chihuahua. Los resultados de dicho estudio permiten medir la prevalencia correlacional entre el bullying y fracaso escolar, uso de drogas y la poca o nula aceptación de reglas, tanto en el entorno familiar como en el escolar, así como conductas predelictivas que pueden predecir futuras conductas criminales en los adolescentes. Son datos recolectados que en primera instancia deducen cómo la práctica indiscriminada de bullying puede revelar conductas criminales y la importancia de implementar una materia dentro del plan de estudios de nombre Ciencias de la prevención, que permitiría que los alumnos conozcan dos temas de gran importancia: la prevención del delito y la prevención victimal, para con ello, evitar la victimidad y la personalidad antisocial en los centros escolares.
COVID-19 Vaccine Uptake Among Nursing Home Staff via Statewide Policy: The Mississippi Vaccinate or Test Out Policy
Authors: Syme Maggie L. , Gouskova Natalia , Berry Sarah D.
Published: March 2022

Objectives. To examine whether COVID-19 vaccine mandates that allow a test-out exemption for nursing home staff are associated with increased staff vaccination rates in nursing homes.

Methods. Using the National Healthcare Safety Network data, we conducted analyses to test trends over time in statewide staff vaccination rates between June 1, 2021, and August 29, 2021, in Mississippi, 4 adjacent states, and the United States overall.

Results. COVID-19 staff vaccination rates increased slowly following Mississippi enacting a vaccinate-or-test-out policy, achieving small, but statistically greater gains than most comparator states. Yet, staff vaccination rates in Mississippi remained well below the national average and similar numerically to surrounding states without mandates.

Conclusions. Mississippi’s COVID-19 vaccinate-or-test policy was ineffective in meaningfully increasing staff vaccination rates. For COVID-19 nursing home mandates to be effective while still balancing the staff turnover risks, facilities might consider a more stringent or hybrid approach (e.g., test-out option not offered to new staff).

Public Health Implications. Statewide COVID-19 vaccine mandates, when given a test-out option, do not appear to be an effective strategy to meaningfully increase nursing home staff COVID-19 vaccination. (Am J Public Health. 2022;112(5):762–765. https://doi.org/10.2105/AJPH.2022.306800 )

Published: March 2022

This cross-sectional survey investigates the influence of youths’ religiosity on their attitude towards people with disabilities. The Muslim religiosity questionnaire and multidimensional attitudes scale towards persons with disabilities were used to survey 733 youths from the federal university in the United Arab Emirates. Results indicated that the youths were religious and had positive attitudes towards people with disabilities. An increase in religiosity is associated with a positive attitude towards disability, and both religiosity and total family income had a positive impact on the attitude towards people with disabilities. Reducing inequalities by including persons with disabilities is one of the objectives of the UN 2030 Agenda for Sustainable Development. Policies should aim to enhance curriculum, improvise public guidelines and partner with associated faith-based leaders to build an inclusive society for people with disabilities, thus helping to achieve sustainable development goals.
