Research into the stiffness of beam-column joints of modular prefabricated buildings
Authors: Shirokov Viacheslav S. , Alpatov Vadim Yu. , Gordeyev Evgeniy A.
Published: February 2021

Introduction. Rotational stiffness of a joint in modular building frames is the subject of this research. The stiffness of joints has a direct impact on the analysis of building structures. However, Russian design standards lack any clear instructions concerning this characteristic. Modular buildings have non-standard joints; therefore, it is necessary to study their rotational stiffness. The purpose of this work is to differentiate rigid joints, connecting a channel beam to a square pipe column, from semi-rigid ones.

Materials and methods. Joints are classified according to Eurocode 3, that sets the limits for pinned, rigid and semi-rigid joints. The component-based finite element model implemented in the IDEA StatiCA software package is used to calculate the value of initial rotational stiffness. Two types of joints were studied: one that has an angle stiffener, and the other that has none.

Results. The values of rotational stiffness of beam-column joints are obtained. It’s been identified that the joints of spans, typical for modular buildings, having no angle stiffeners, should be classified as semi-rigid and their rotational stiffness should be taken into account in designs. The variability of rotational stiffness of joints, having angle stiffeners, is nonlinear. If the dimensions of an angle stiffener are close to those of the cross section of a column, rotational stiffness rises steeply and joints turn rigid.

Conclusions. A nomogram was made for various sections of channels and pipes having minimum angle stiffener dimensions, ensuring the rigidity of beam-column joints. The nomogram is recommended as a guidance for setting angle stiffener dimensions.

Numerical and analytical calculation of the buckling of elastic prismatic rods under the action of axial compressive loading with account for the dead load
Authors: Yazyev Serdar B. , Chepurnenko Anton S. , Avakov Arthur A.
Published: February 2021

Introduction. The article addresses the problem of stability of compressed rods with regard for the dead load. A resolving differential equation of the second and fourth order with respect to dimensionless deflection is obtained. A methodology underlying numerical-analytical and numerical solutions to the obtained equation is proposed. It employs the power series and the finite difference method. As a result, the numerical solution is reduced to the generalized eigenvalue problem. A comparison with the solution developed by other authors is provided.

Materials and methods. The problem of determining critical values, applicable to rods, is formulated as the task of identifying the domain of these values depending on the boundary conditions and dimensionless coefficients α and β that correspond to the concentrated force and the distributed load of the dead load. The function, approximating the deflection, represents the power series having indefinite coefficients. The objective function represents converging power series having unknown coefficients. The solution to the stability problem of a prismatic rod is obtained in the MatLab environment. The values of α and β are found; they correspond to the minimal critical load.

Results. Several problems were solved and new solutions were compared with the well-known ones in order to test the methodology.

Conclusions. Unlike analytical solutions, the proposed methodology allows to solve the problem, if the ends of the rod are fixed arbitrarily. One can also take account of the rod stiffness that varies along the length, as well as the heterogeneity of the rod. Test problems show good convergence with the data provided in the sources. In the future, the methodology will take account of creep. A higher quality analytical solution, surpassing other existing methods, is demonstrated.
Stability of eccentrically compressed reinforced concrete elements under special impacts with account taken of shear deformations
Authors: Savin Sergey Yu.
Published: February 2021

Introduction. When structural models of reinforced concrete frameworks of buildings and structures are designed, bars and plates simulate structural elements. As rule, such an approach entails rigid cohesion between reinforcement bars and concrete; thus, it fails to simulate the true nature of their joint action in the areas having high stress gradients, for example, beam-column junctions. In this regard, it’s necessary to plot analytical dependencies and develop a methodology for the stability analysis of the strain state of bar elements of reinforced concrete frameworks of buildings and structures with account taken of shear deformations at the interface between a reinforcement bar and concrete.

Materials and methods. The Rzhanitsyn composite bar theory was applied to design a stress-strain model of an eccentrically compressed reinforced concrete bar. The Kelvin-Voigt model is proposed as a rheological stress-strain model of static and dynamic resistance of concrete.

Results. Analytical dependencies needed to analyze the stress-strain state and stability of an eccentrically compressed reinforced concrete bar exposed to dynamic loading, were plotted. These dependencies take account of shear deformations at the interface between reinforcement bars and concrete. A nonlinear calculation algorithm was developed; it took account of the elastoplastic behavior of concrete and steel bars, when the stability problem of an eccentrically compressed dynamically loaded reinforced concrete bar was solved.

Conclusions. Analytical dependencies, obtained by the author, allow to take account of shear deformations at the interface between reinforcement bars and concrete in eccentrically compressed reinforced concrete elements of frameworks of buildings and structures for the purpose of analyzing the stability of such elements exposed to special impacts caused by the unexpected failure of one bearing element of a structural system.
Simulation of the process of free spreading of a two-dimensional water flow behind pressure-free holes
Authors: Kokhanenko Victor N. , Aleksandrova Mariya S. , Kondratenko Anatolij I.
Published: February 2021

Introduction. Construction of hydraulic structures must meet high reliability requirements applicable to water supply channels, free-flow pipes, and open spillways. Any analysis of hydraulic structures must take account of the dynamic properties of flows that the structures accommodate. The theory of one-dimensional free flows, used in practice, has a number of general guidelines, but lack any details. The co-authors take advantage of the theory of two-dimensional free flows, namely, the method of characteristics proposed and developed in the works of I.A. Sherenkov.

Materials and methods. In her works, B.T. Emtseva suggests that a uniform flow can be coupled with a general flow only with the help of an intermediate “simple wave” flow, but this statement has no proof. We identified and analyzed a general flow in the plane of the hodograph. Thereafter, characteristics of the first family of the flow were determined. A transition to the physical plane of the flow allowed to determine the coordinates of the points of characteristics of the second family. This allowed to find the coordinates of the points of the extreme streamline and to determine its geometry.

Results. The proposed mathematical model complied with the system of equations, describing the flow, and the boundary conditions when it was applied to the boundary problem of the free spreading of a stormy, potential, two-dimensional in plan, free, stationary water flow and its free inflow into a wide horizontal smooth channel.

Conclusions. The concept of a general flow (previously unknown) and equations of motion in the plane of the velocity hodograph made it possible to theoretically prove its applicability to the problem of free flow spreading. A simple analytical solution is obtained in the plane of the velocity hodograph. The theoretical significance of this mathematical model consists in the possibility of its step-by-step application to practical problems and its complication from the identification of the main regularities of a simplified model of a potential flow to the practical use of simulation results. The implementation of the methodology in the form of software will make it usable by designers of hydraulic structures. This is the first stage of problem solving, and at further stages resistance will be taken into account.
El desafío de la trascendencia en tiempos de creatividad
Authors: Sánchez Capdequi Celso
Published: February 2021

De un punto a esta parte, la creatividad se ha convertido en un debate central en las ciencias sociales y en la opinión pública. Abundan las publicaciones y las investigaciones sobre una facultad que define la particularidad de la condición humana posiblemente como ninguna otra. La creatividad constituye un atributo estructural y estructurante de la acción humana, sin embargo, en nuestros días también comparece como realidad estructurada que dibuja un modelo de acción afín a la experimentación estética, pero, al mismo tiempo, regulado y rutinizado (Sánchez Capdequi, 2019). Su institucionalización como discurso normal se convierte en un hecho social inédito para las ciencias sociales. Así como disciplinas con más calado atemporal que la propia sociología, como la filosofía, la antropología y la estética, se han detenido en ella respectivamente como un incremento del ser (Gadamer), como una imaginación en apertura (Gehlen) y como itinerario simbólico afín al noúmeno de las cosas (Kant), la sociología, hasta fechas recientes, ha contado con ella, pero sin explicitarla y analizarla específicamente. Su presencia se ha dado por supuesto en episodios tan pegados a la modernidad como la revolución política, el descubrimiento científico, la moda, la innovación tecnológica, entre otros. Es en la actualidad cuando cobra centralidad y dimensión de problema en un actor contemporáneo que no sólo crea originalidad, sino que, además, tiene que crearla.

Promoting Motivational Interviewing in Primary Care: More Than Intention
Authors: Hershberger Paul J. , Martensen Lori S. , Crawford Timothy N. , Bricker Dean A.
Published: February 2021

Introduction: Interacting with patients in a manner that furthers self-responsibility for health is an important skill for primary care clinicians. Motivational interviewing (MI) is such an approach to patient engagement, but it remains to be more widely implemented. In a program training health professionals and health professions students in MI, we examined posttraining attitudes and intentions regarding the utilization of MI. Of particular interest was how posttraining intentions were associated with self-reported action 1 month later.
Methods: We obtained immediate posttraining and 30-day follow-up data from 209 participants regarding intent to utilize the MI approach (self-reported implementation at the follow-up interval), impact on confidence with patient interaction, and perceived importance of the training. We analyzied frequencies and percentages for all categorical/ordinal variables to describe the participants and the survey question responses.
Results: While 91.5% of participants intended to incorporate MI into their approach with patients (to a moderate or great extent) at posttraining, only 48.7% reported that they had actually implemented the MI approach (to a moderate or great extent) 30 days later. However, another 32.1% indicated that they had occasionally utilized MI. Attitudes toward the importance of MI training and the impact of training on confidence remained strong over the 30 days.
Conclusion: Achieving more widespread implementation of the MI approach in the primary care setting is likely to be less dependent on convincing clinicians about its importance for patient engagement, but rather on the translation of intent to actual practice and implementation.

Leaf water relations in epiphytic ferns are driven by drought avoidance rather than tolerance mechanisms
Authors: Campany Courtney , Pittermann Jarmila , Baer Alex , Holmlund Helen , Schuettpelz Eric , Mehltreter Klaus , Watkins James (Eddie)
Published: February 2021

Opportunistic diversification has allowed ferns to radiate into
epiphytic niches in angiosperm dominated landscapes. However, our
understanding of how ecophysiological function allowed establishment in
the canopy and the potential transitionary role of the hemi-epiphytic
life form remain unclear. Here, we surveyed 39 fern species in Costa
Rican tropical forests to explore epiphytic trait divergence in a
phylogenetic context. We examined leaf responses to water deficits in
terrestrial, hemi-epiphytic, and epiphytic ferns and related these
findings to functional traits that regulate leaf water status. Epiphytic
ferns had reduced xylem area (-63%), shorter stipe lengths (-56%),
thicker laminae (+41%), and reduced stomatal density (-46%) compared
to terrestrial ferns. Epiphytic ferns exhibited similar turgor loss
points, higher osmotic potential at saturation, and lower tissue
capacitance after turgor loss than terrestrial ferns. Overall,
hemi-epiphytic ferns exhibited traits that share characteristics of both
terrestrial and epiphytic species. Our findings clearly demonstrate the
prevalence of water conservatism in both epiphytic and hemi-epiphytic
ferns, via selection for anatomical and structural traits that avoid
leaf water stress. Even with likely canalized physiological function,
adaptations for drought avoidance have allowed epiphytic ferns to
successfully endure the stresses of the canopy habitat.

The congenital sideroblastic anemias (CSAs) are a heterogeneous group of
inherited disorders of erythropoiesis characterized by pathologic
deposits of iron in the mitochondria of developing erythroblasts.
Mutations in the mitochondrial glycine carrier SLC25A38 cause the most
common recessive form of CSA. Nonetheless, the disease is still rare,
there being fewer than 70 reported families. Here we describe the
clinical phenotype and genotypes of 31 individuals from 24 families,
including 11 novel mutations. We also review the spectrum of reported
mutations and genotypes associated with the disease, describe the unique
localization of missense mutations in transmembrane domains and account
for the reoccurrence of several alleles in different populations.
Prone-position computed tomography in the late phase for detecting intracardiac thrombi in the left atrial appendage before catheter ablation for atrial fibrillation

Published: February 2021

Background: Contrast computed tomography (CT) is a useful tool for the
detection of intracardiac thrombi. We aimed to assess the accuracy of
the late-phase prone-position contrast CT (late-pCT) for thrombus
detection in patients with persistent or long-standing persistent atrial
fibrillation (AF). Methods: Early and late-phase pCT were performed in
300 patients with persistent or long-standing AF. If late-pCT did not
show an intracardiac contrast defect (CD), catheter ablation (CA) was
performed. Immediately prior to CA, intracardiac echocardiography (ICE)
from the left atrium was performed to confirm thrombus absence and the
estimation of the blood velocity of the left atrial appendage (LAA). For
patients with CDs on late-pCT, CA performance was delayed, and late-pCT
was performed again after several months following oral anticoagulant
alterations or dosage increases. Results: Of the 40 patients who
exhibited CDs in the early phase of pCT, six showed persistent CDs on
late-pCT. In the remaining 294 patients without CDs on late-pCT, the
absence of a thrombus was confirmed by ICE during CA. In all six
patients with CD-positivity on late-pCT, the CDs vanished under the same
CT conditions after subsequent anticoagulation therapy, and CA was
successfully performed. Furthermore, the presence of residual contrast
medium in the LAA on late-pCT suggested a decreased blood velocity in
the LAA (≤ 15 cm/s) (sensitivity = 0.900 and specificity = 0.621).
Conclusions: Late-pCT is a valuable tool for the assessment of
intracardiac thrombi and LAA dysfunction in patients with persistent or
long-standing persistent AF before CA.

Authors: Yu Li Ting , wang zhuo , zhou fen , Shen Shuangshuang , Zhang Shunguo , Gao Yijin
Published: February 2021

Abstract Children aged 2-12 years scheduled to receive moderately or
highly emetogenic chemotherapy were randomly assigned to arm-A
(fosaprepitant) or arm-B (aprepitant). Children recruited to arm-A
received intravenous ondansetron plus dexamethasone followed by
fosaprepitant infusion. Children recruited to arm-B received the same
drugs as those given to children in arm-A, except that fosaprepitant was
substituted with aprepitant. The primary end point of the study was to
determine the proportion of patients who achieved a CR, defined as no
vomiting, no retching, and no use of rescue medication, the proportion
of patients who achieved a CR during the acute phase (0-24 hours) after
administration of the last dose of chemotherapy. Secondary end points
were the proportion of patients who achieved a CR during the 24-120
hours (delayed phase) and overall after administration of the last dose
of chemotherapy. Results: One hundred and eight patients were analyzed
(55 in the fosaprepitant arm and 53 in the aprepitant arm). CR rates
were higher in the fosaprepitant arm compared with the aprepitant arm
during the acute phase (95 % vs 79 %, P =0.01< 0.05),
delayed phase (71 % vs 66 %, P =0.89 ), and overall phase (69 % vs 57
%, P =0.18). Furthermore, the demand of rescue anti-emetics observed in
fosaprepitant arm (7 %) has no difference with aprepitant arm (11 %).
Conclusion: Addition of fosaprepitant to ondansetron and dexamethasone
is more effective than aprepitant for the prevention of acute vomiting.
Approximating common fixed points by a new faster iteration process

Published: February 2021

In this paper, we propose a three-step iteration process and show that this
process converges faster than a number of existing iteration processes. We
give a numerical example followed by graphs to validate our claim. We prove
strong and weak convergence results for approximating common fixed points
for two nonexpansive mappings. Again we reconfirm our results by examples
and tables. Further, we provide some applications of the our iteration
process.

Local solutions of Painlev? equations P1, P2, P4, as well as of the
equations S1, S2, S4 satisfied by their Hamiltonians, can be extended to
functions meromorphic in C. This way they become a point of interest for
value distribution theory. Distribution of values of solutions of P1, P2 and
P4 is already well described. In the paper we discuss mostly S1, S2 and S4
in this context. In particular, we pay attention to deficient, asymptotic
and ramified values of solutions of these equations.
Characterization of mixed n-Jordan and pseudo n-Jordan homomorphisms
Authors: Neghabi Masoumeh , Bodaghi Abasalt , Zivari-Kazempour Abbas
Published: February 2021

In this article, a new notion of n-Jordan homomorphism namely the mixed
n-Jordan homomorphism is introduced. It is proved that how a mixed (n +
1)-Jordan homomorphism can be a mixed n-Jordan homomorphism and vice versa.
By means of some examples, it is shown that the mixed n-Jordan homomorphisms
are different from the n-Jordan homomorphisms and the pseudo n-Jordan
homomorphisms. As a consequence, it shown that every mixed Jordan
homomorphism from Banach algebra A into commutative semisimple Banach
algebra B is automatically continuous. Under some mild conditions, every
unital pseudo 3-Jordan homomorphism is a homomorphism.

Authors: Radojkovic Bojana , Jegdic Bore , Kovacina Jovanka , Stevanovic Sanja , Marunkic Dunja
Published: February 2021

The influence of the microstructure of X5CrNi18-10 stainless steel welded joint on its resistance to general, pitting, and intergranular corrosion was analyzed. The structure of weld metal, heat affected zone (HAZ) and base metal before and after electrochemical testing was analyzed using SEM/EDS. The influence of the roughness level of the welded joint on its resistance to the mentioned types of corrosion was also examined. Although the degree of sensitization of HAZ was significantly lower than the limit value, HAZ showed a noticeably greater tendency to general and pitting corrosion than weld metal and base metal. Polishing has been shown to improve significantly the corrosion resistance of HAZ than in other parts of a welded joint.
Glucose Control, Sulfonylureas, and Insulin Treatment in Elderly People With Type 2 Diabetes and Risk of Severe Hypoglycemia and Death: An Observational Study
Authors: Ling Suping , Zaccardi Francesco , Lawson Claire , Seidu Samuel I , Davies Melanie J , Khunti Kamlesh
Published: February 2021

Objective: To estimate the relative and absolute risk of severe hypoglycemia
and mortality associated with glucose control, sulphonylurea and insulin treatment
in elderly people with type 2 diabetes.

Research Design and Methods: We identified elderly subjects (≥70 years) with
type 2 diabetes between 2000 and 2017 in the UK CPRD primary care database with
linkage to hospitalization and death data. Subjects with three consecutive HbA1c
<7% (53 mmol/mol) while on insulin and/or sulphonylurea within 60 days prior
to the third HbA1c (exposed) were matched to not exposed. Hazard
ratios (HRs) and absolute risks were estimated for hospitalizations for severe
hypoglycemia and cardiovascular and non-cardiovascular-related mortality.

Results: Among 22,857 included subjects (6288 [27.5%] exposed, of which
5659 [90.0%] on sulphonylurea), 10,878 (47.6%) deaths and 1392 (6.1%) severe hypoglycemic
episodes occurred during the follow-up. Compared to non-exposed, the adjusted HR
in exposed was 2.52 (95% CI: 2.23, 2.84) for severe hypoglycemia; 0.98 (0.91,
1.06) for cardiovascular mortality; and 1.05 (0.99, 1.11) for non-cardiovascular
mortality. In a 70-, 75-, 80- and 85-year-old subject, the 10-year risk of
severe hypoglycemia was 7.7%, 8.1%, 8.6%, and 8.4% higher than non-exposed while
differences for non-cardiovascular mortality ranged from 1.2% (-0.1, 2.5) in a
70-year-old to 1.6% (-0.2, 3.4) in an 85-year-old subject. Sulphonylurea and insulin
were more relevant predictors of severe hypoglycemia and death than glucose
levels.

Conclusions: Elderly
subjects with type 2 diabetes and low HbA1c on sulphonylurea or
insulin treatment experienced a substantially higher risk of hospitalization
for severe hypoglycemia but had no clear evidence of increased risks of
mortality.
Vascular recognition system based on photoacoustic detection
Authors: Zhang Chuncheng , Liu Guodong , Xie Zhihua , Shu Zhenghua , Ren Zhong , Yao Qingkai
Published: February 2021

Currently, biometrics are widely used in recognition technology; however, biometric recognition systems are vulnerable to malicious spoofing attacks. Thus, the security of such systems requires enhancements. This paper reports a novel vascular recognition system based on simple photoacoustic imaging to resist spoofing attacks. The amplitude and the delay of the maximum-value arrival time of the photoacoustic signal were used for detecting the vascular optical absorption and depth prior to vascular imaging. The proposed photoacoustic detection system detected fake vascular biometrics and demonstrated improved recognition rates with resistance toward spoofing attacks. In addition, the recognition rate increased from 95% to 97.5% as only real vasculatures were imaged. Moreover, the results verified the feasibility of using photoacoustic images for vascular recognition. The proposed photoacoustic system is noninteracting, low cost, robust, and highly anticounterfeiting.

La pobreza ha sido un problema a nivel mundial, el cual en México se ha presentado con mayor incidencia en los estados del sur. El objetivo de este trabajo fue elaborar el índice multidimensional de pobreza con la inclusión de las tecnologías de información y comunicación para generar una intervención pública, disminuir la pobreza y mejorar el bienestar, enfocado en salud, nutrición, características de la vivienda, equipos de tecnologías de información y comunicación, internet, redes sociales y saneamiento. La investigación se llevó a cabo en el municipio de Tepelmeme Villa de Morelos del estado de Oaxaca. Para ello, se aplicó una encuesta de pobreza a 128 hogares en tres comunidades rurales y se elaboró un índice multidimensional de pobreza con la metodología de Alkire y Foster. En los resultados se encontró un índice de 0.431 para una línea de pobreza de 50 %. Los indicadores que contribuyeron a la pobreza en mayor cantidad fueron equipamiento del hogar (15.21 % para número de aparatos eléctricos, y 14.77 % para automóvil), salud (7.76 % para visita al médico especialista y 6.49 % para visita al médico general), y nutrición (7.51 % para proteína, 6.3 % para vegetales y 5.1 % para frutas). Asimismo, se realizó una simulación de una intervención pública del gobierno, para lo cual se ajustaron los valores de los indicadores de pobreza con mayor contribución al índice y se volvió a calcular el índice de pobreza. Con esto se logró disminuir el índice multidimensional de pobreza a un valor de 0.355. Se concluyó que se debe hacer una intervención del gobierno para realizar una reasignación de recursos, por lo que se planteó un escenario para disminuir la pobreza.

Textbooks are handy means in EFL classrooms. However, they may have some lacking points in terms of implementation. EFL teachers’ opinions are crucial in that point. Taking this into account, the current study seeks to investigate the effectiveness of the textbooks used at MONE from teachers’ view. 102 EFL teachers from 7 regions of Turkey are targeted for the data collection. The participants involved are working in primary, secondary and high schools all over Turkey. The data are collected in 2 months in Covid-19 days. The data collection instrument is a five-point likert scale teacher questionnaire. Hence, this study is a quantitative one for which the data obtained are analyzed through SPSS. One sample T-tests, Pearson Correlation Statistics and Descriptive Statistics are utilized in this study. This study reveals that English textbooks are inadequate in terms of layout, design, activities and skills. On the other hand, the teachers find subject, content and language type used in the textbooks appropriate. Most of the teachers are of the opinion that the textbooks are easily adaptable. Nevertheless, the teachers are knowledgeable enough for overcoming the deficiencies and applying the best method for their students regardless of the textbook. Further studies could be conducted by interviewing with the teachers about the drawbacks found in textbooks.

Purpose: This study aimed to identify the genres that require second/foreign language learners to draw on their narrativecompetence along with the related level descriptors in the Common European Framework of Reference for Languages (CEFR)and the CEFR Companion Volume with New Descriptors, which serve to achieve coherence in the structuring of languagelearning/teaching processes by standardizing the way language ability is described.Design/Methodology/Approach: In this qualitative research, data were collected from the Common European Framework ofReference for Languages(2001) and the CEFR Companion Volume (2018) published by the Council of Europe through documentreview, and a content analysis was conducted. The processes of collecting, categorizing, and preparing the data for descriptionwere carried out sequentially.Findings: In the CEFR, written texts such as novels, personal letters, short stories, short newspaper articles (that describeevents), comic strips, photo stories, travelogues, news items, biographies, cartoons, advertisements, postcards, messages,notes, e-mails, blogs and fairy tales, which can be considered as narrative texts, are mentioned. In addition, personalnarratives, films, and anecdotes, which are not written genres, are also encountered. It has been found out that the leveldescriptors that can be functional in drawing inferences about whether the learners developed a narrative competence or notare structured gradually from level A to C in the CEFR. Upon analysis of the level descriptors regarding narrative texts andnarrative competence with respect to the four skills, it has been noted that the level descriptors that can be associated withnarrative texts and competence at all levels were the fewest in number regarding speaking and listening and the highestregarding reading.Highlights: Even though other genres are not referred to directly in the CEFR, a general framework about other genres is evidentin the text. The categorization of the narrativity-related level descriptors based on proficiency levels and skills is thought tocontribute to the designation of the learning objectives that reflect the language-specific features of narrative structures basedon the level descriptors in the CEFR, and thus to the enhancement of the quality of curriculum, materials, and activities to bedeveloped.
