Validating young learners’ plurilingual repertoires as legitimate linguistic and cultural resources in the EFL classroom
Authors: Cutrim Schmid Euline 
Published: July 2021

Abstract
In the last decades, the applied linguistics literature has increasingly called for more classroom-based research focusing on language teaching approaches that embrace students’ plurilingual repertoires as valuable linguistic and cultural resources for learning and affirm learners’ plurilingual identities as legitimate and appropriate in the classroom context. This paper discusses research findings of an empirical investigation that responded to this call. The study examined the impact of the use of plurilingual tasks in the English as foreign language (EFL) classroom on language learning processes and learners’ identity construction. Five case studies were conducted in four primary schools and one secondary school in Germany. Research data were collected from multiple sources such as field notes, video recording of school lessons, in-depth interviews with teachers, teachers’ reflective journals, anonymous questionnaires, and focus group interviews with learners. The research findings have shown that the use of plurilingual tasks in the EFL classroom created enhanced opportunities for the learners (a) to share aspects of their identities that were previously ignored in the school context (b) to use their diverse language abilities as resources in the language learning process and (c) to be actively involved in explicit reflective thinking about language and culture.
To the problem of forming the equation system for pressure swing adsorption mathematical model
Authors: Golubyatnikov Oleg , Akulinin Evgeny , Dvoretsky Stanislav , Dvoretsky Dmitry 
Published: July 2021

Abstract
The complexity of the pressure swing adsorption (PSA) mathematical model, the need for its multiple calculations to reach the cyclic steady state and a large number of functional dependencies lead to unstable numerical circuits, physically unrealistic oscillations in adsorption profiles, an increase in the calculation time, and the failure of the solver. The paper proposes an approach to optimizing the calculation process, which consists in finding a reasonable balance between the completeness of the PSA mathematical model and the accuracy of the results obtained. The effectiveness of the approach is demonstrated on the example of air oxygen enrichment and hydrogen recovery from synthesis gas. The gas separation processes were simulated for the two-adsorber PSA unit with a granulated 13X adsorbent. The effect of the changes in the model coefficients on its accuracy in the operating range of input variables is investigated. A distinctive feature of this study is the recommendations for choosing a set of the model equations to calculate the PSA processes which are particularly relevant when solving optimization problems with uncertainty. The productivity, cycle duration, the diameter of the adsorbent particles and the flow rate, at which it is advisable to use the isothermal and external diffusion reduced PSA model in the calculations, are established, which will save at least 24.3 and 47.1% of the CPU time with a small loss in accuracy. The proposed approach can be used to form a set of equations for the PSA, rPSA, ultra rPSA, VSA, VPSA models, separation of various gas mixtures on various adsorbents.

Abstract

Objectives
The aim of this study was to evaluate the resilience of girls with central precocious puberty (CPP) during treatment with a gonadotropin-releasing hormone agonist (GnRHa) and compare these results with their healthy peers.

Methods
The Connor–Davidson Resilience Scale (CD-RISC) is a self-report scale used to quantify resilience, which is divided into seven subgroups (hardiness, coping, flexibility, purpose, optimism, regulation of emotion and cognition (REC), and self-efficacy). Fifty-one girls with CPP receiving GnRHa treatment and 51 healthy controls were involved in the study. Anthropometric measurements were evaluated and CD-RISC was performed at least six months after the initiation of GnRHa treatment.

Results
There was no statistically significant difference between the anthropometric evaluations of girls with CPP and the control group. Similarly, the total score and subgroup scores of patients with CPP and the control group showed no statistically significant difference. In the correlation analysis, there was a weak negative correlation between height and flexibility (r=−0.314 p=0.025), height SDS and flexibility (r=−0.254 p=0.092), height SDS, and purpose (r=−0.285 p=0.058). Also, there was a weak negative correlation between REC and weight (r=−0.435 p=0.003), REC and weight SDS (r=−0.461 p=0.002), REC and height (r=−0.269 p=0.077), REC and height SDS (r=−0.322 p=0.033), REC and BMI (r=−0.289 p=0.058), and REC and BMI SDS (r=−0.353 p=0.019).

Conclusions
The resilience of girls with CPP treated with GnRHa was found to be similar to their healthy peers. The early diagnosis of the disease and adequate treatment may decrease the discrepancy of somatic changes between girls with CPP and their peers, which may help them to overcome the stress of CPP and long-term treatment.

Abstract

Objectives
Biopsy morphology (surface/depth ratio) and sample processing might affect pharmacological measurements in peritoneal tissue.

Methods
This is an ex-vivo study on inverted bovine urinary bladders (IBUB). We compared cisplatin (CIS) and doxorubicin (DOX) concentration in 81 standardized transmural punch biopsies of different diameters (6 and 12 mm). Then, we assessed the effect of dabbing the peritoneal surface before analysis. After automatized tissue homogenization with ceramic beads followed by lyophilisation, DOX concentration was quantified by high-performance liquid chromatography (HPLC), CIS concentration by atomic absorption spectroscopy. Experiments were performed in triplicate; the analysis was blinded to the sample origin. Comparisons were performed using non-parametric tests.

Results
Concentrations are given in mean (CI 5–95%). Results were reproducible between experiments (for CIS p=0.783, for DOX p=0.235) and between different localizations within the IBUB (for CIS p=0.032, for DOX p=0.663). Biopsy diameter had an influence on CIS tissue concentration (6 mm biopsies: 23.2 (20.3–26.1), vs. 12 mm biopsies: 8.1 (7.2–9.2) ng/mg, p<0.001) but not on DOX: (0.46, 0.29–0.62) vs. 0.43 (0.33–0.54) ng/mg respectively, p=0.248). Dabbing the peritoneal surface reduced DOX tissue concentration (dry biopsies: 0.28 (0.12–0.43) vs. wet biopsies: 0.64 (0.35–0.93) ng/mg, p=0.025) but not CIS (23.5 (19.0–28.0) vs. 22.9 (18.9–26.9) ng/mg, respectively, p=0.735).

Conclusions
Measurements of drug concentration in peritoneal tissue can be influenced by the biopsy’s surface/depth ratio and after drying the biopsy’s surface. This influence can reach a factor three, depending on the drug tested. The biopsy technique and the pre-analytical sample preparation should be standardized to ensure reliable pharmacological measurements in peritoneal tissue.

Authors: Kong Wenyuan , Huang Yongfa , Guo Zhan , Zhang Xiaoyong , Chen Yu 
Published: July 2021

Abstract
This article reports the experimental behavior of square hollow stainless steel tubular trusses under static loading. A total of five specimens, including three trusses with K-joint, one truss with N-joint, and one truss with T-joint, were tested to study the effect of different outer widths of brace members and the types of joint on the flexural performance of square hollow stainless steel tubular trusses. The failure modes, flexural rigidity, load carrying capacity, ductility, load versus displacement curves, and load versus strain curves of all the tested specimens are presented. It can be seen that the chords of all specimens experienced surface plasticity. The test results indicate that the specimen with T-joint has the best ductility. The flexural rigidity of the truss with the K-joint is better than that of specimens with N-joint or T-joint. The flexural rigidity of trusses with the K-joint was found to increase with the increase of outer width (D) of the brace members varying from 38 to 80 mm. Besides, the load-carrying capacity per unit weight of the specimen with T-joint is better than that of specimens with N-joint or K-joint.

Time-specific average estimation of dynamic panel regressions
Authors: Chu Ba 
Published: July 2021

Abstract
This paper introduces an unbiased estimator based on least squares involving time-specific cross-sectional averages for a first-order panel autoregression with a strictly exogenous covariate. The proposed estimator is straightforward to implement as long as the variables of interest have sufficient time variation. The number of cross-sections (N) and the number of time periods (T) can be large, and there is no restriction on the growth rate of N relative to T. It is demonstrated via both theory and a simulation study that the estimator is asymptotically unbiased, and it can provide correct empirical coverage probabilities for the ‘true’ coefficients of the model for various combinations of N and T. An empirical application is also provided to confirm the feasibility of the proposed approach.

We evaluated the phytosanitary risk associated with illegal importation of pest-infested plant commodities into South Africa. Samples were collected from different South African ports of entry over 8 years (2011 to 2019) and data were analysed descriptively using Statistical Software Package. Pests were frequently detected on commodity species such as Citrus (18.31%), Zea mays (13.22%), Phaseolus vulgaris (12.88%), Musa spp. (9.15%) and Fragaria ananassa (5.08%). The highest number of pests intercepted occurred on fresh fruits (44.06%), followed by grains (26.44%) and vegetables (14.23%). The most intercepted organisms were Callosobruchus rhodesianus (7.79%), Dysmicoccus brevipes (7.11%), Callosobruchus maculates (6.10%) and Phyllosticta citricarpa (4.74%). The majority of intercepted organisms were non-quarantine organisms (70.50%), followed by pests of unknown status (17.28%), quarantine pests (10.84%) and potential quarantine pests (1.35%). Phyllosticta citricarpa, Bactrocera dorsalis, Spodoptera frugiperda and Prostephanus truncatus were the only quarantine pests intercepted in terms of South African regulatory status. The interception was mainly from southern African countries, particularly Mozambique, Zimbabwe and Eswatini. The findings present the level of phytosanitary risk associated with illegal importation and/or non-compliance in regard to plants and plant commodities from different countries through South African ports of entry. Crop production, biodiversity, food security, existing export markets, and access to new export markets could be threatened as importing countries may impose stringent phytosanitary measures to limit the chances of introduction and establishment of quarantine pests into their territories. Significance

Illegal importation of plant commodities may lead to the introduction, establishment and spread of pests that are of quarantine significance to South Africa.
Introduction of pest species such as Phyllosticta citricarpa, Bactrocera dorsalis, Spodoptera frugiperda and Prostephanus truncatus into South Africa could result in undesirable impacts on the ecosystem, agriculture, biodiversity and economy of the country.
Access to new export markets of plant commodities could be threatened as importing countries may impose stringent phytosanitary measures to limit the chances of introduction and establishment of these quarantine pests into their territories.

Bu nedenle sağlık çalışanlarının madde kullanan bireylerin sosyal ağlarına yönelik bilgi ve farkındalık düzeyleri arttırılmalıdır.
Comparison of Single-Well Microseismic Focal Mechanism Inversions with Different Source Models
Authors: Li Han , Chang Xu , Hao Jinlai , Wang Yibo 
Published: July 2021

ABSTRACT
Through downhole monitoring, the focal mechanisms of microearthquakes can be quantitatively determined, thus providing valuable information for characterizing the fracturing process and the in situ stress status. The double-couple (DC) and moment tensor (MT) source models are commonly used to study microearthquakes. However, the DC model fails to include non-DC mechanisms, and MT inversion from single-well data is still challenging. One possible way to address this is using the shear–tensile general dislocation (GD) source model. We provide a detailed comparison of the DC, GD, and MT models, and introduce the differences in their modeling and inversion theories. These three models are described by four, five, and six parameters, and correspond to a single point, a straight line, and the entire space in the Hudson source-type plots, respectively. Both the DC and GD models yield nonlinear inversions, whereas the MT inversion is linear. Synthetic tests set up from a field single-well monitoring case are performed to study the resolvability of the DC, GD, and MT models in single-well focal mechanism inversions. The results indicate that the inversion error increases from DC→GD→MT for a single-well acquisition system, and the GD and DC inversions are both stable, whereas the MT inversion deviates from the inputs in cases with a perfectly vertical receiver array, 5% model velocity perturbations, 10 m horizontal source location errors, or 40% noise levels. We also find that the focal mechanism inversion mainly depends on the horizontal source–receiver azimuth coverage, and that the nonvertical well direction is helpful for constraining single-well inversions. According to our study, focal mechanism inversions based on the GD model can obtain reliable solutions from near-vertical single-well data, which will help improve non-DC earthquake studies.
A Sample Generation of Scenario Earthquake Shaking Maps via a Combination of Modal Decomposition and Empirical Copula toward Seismic Hazard Assessment
Authors: Imai Ryuta , Kasui Naoki , Iwaki Asako , Fujiwara Hiroyuki 
Published: July 2021

ABSTRACTTo quantify variations in seismic hazard assessment, a large number of scenario earthquake shaking maps (hereafter referred to as s-EQ maps for short) are required. In this article, we propose a method to easily generate a large number of s-EQ maps by combining modal decomposition and empirical copula. First, by applying modal decomposition to a set of existing s-EQ maps, we identify a scenario set with a parameter space to reduce the dimensionality of models. Next, we model a probability distribution of the modal coordinates, which we regard as random variables to allow us to induce a probability measure on the parameter space. By applying an empirical copula for modeling the probability distributions, the dependence structure between modal coordinates and the probability distribution of an individual modal coordinate can be discussed independently. Some simulations show that the dependence structure between modal coordinates is important to not distort the seismic hazard assessment. The proposed method can be applied to actual existing s-EQ maps to easily generate a large number of new s-EQ maps that follow the original probability distribution. We also show that variations can be added to the newly generated s-EQ maps by adjusting the empirical copula. Furthermore, we give a generalization of the proposed method to cases with nonequal probabilities of occurrence of existing scenarios.

Authors: Gönültaş Burak Miraç , Edges Charlie 
Published: July 2021

Objective: The present study try to criticise how to approach and intervene in cases of missing children in Turkey in the context of first response, criminal investigation and TV Programmes, thus to offer suggestions on how to make more effective interventions in missing children cases.
Methods: The research adopted a qualitative analysis method and in order to collect data, interviewing and documenting technic from professionals related to Turkish approach (n=5), and speakers and producers of TV programmes (ATV-Sweet Hard and Fox TV- Missing Flowers) related to missing children (n=3) were applied. Then collected data were analysed.
Results: In Turkey, missing cases are investigated in terms of judicial and administrative tasks of police. Search teams, helicopters, lost dogs are used in search studies. When the police learn about the missing case, they conduct field work first, and if there is a sign of abduction, investigative teams are included. TV programs are especially effective in reaching large audiences in child's search studies. Thus, potential eyewitnesses can be reached. Besides, there are inadequency in terms of risk assessment, coordination and psychosocial backup for families.
Conclusion: In relation to the components of missing children cases, Turkey should improve their approach about risk assessment, coordinators and supervising professionals and utilization of the media. The study also reveals the requirements of a general framework for missing children investigations.

Aim To identify clinical and laboratory indexes related with the atherosclerotic plaque (ASP) echogenicity based on results of the analysis of grey-scale median (GSM) in patients aged 40–64 years.Material and methods The study included patients aged 40–64 years with carotid atherosclerosis. The carotid duplex scanning was performed for all patients. The GSM analysis of obtained images was performed with the Adobe Photoshop CS6 software.Results Atherosclerotic cardiovascular diseases were found in 31 (21.4 %) patients. Correlation analysis determined inverse interrelationships between GSM and the body weight index (BWI) (r=–0.359; p<0.0001), waist circumference (r=–0.357; p<0.0001), and levels of uric acid (r=–0.244; p=0.021) and glucose (r=–0.205; p=0.032). According to the regression, statistically significant correlations remained between GSM and BWI as well as the waist circumference after the adjustment for sex and age.Conclusion In patients with carotid atherosclerosis aged 40–64 years, the decrease in ASP GSM was associated with increases in BWI and waist circumference.
