Authors: Chen Junyuan 
Published: January 2024

Abstract
The present study explores Japanese student teachers’ identity construction and transition with focuses on contexts both inside and outside the classroom in the online environment during the COVID-19 pandemic. By integrating language teacher identities as a complex and dynamic entirety rather than detached pieces, this qualitative research study utilizes both narrative inquiry and positioning analysis to examine four Japanese student teacher identities through both discursive construction in discourse and momentary behavior in talk-in-interaction. The data collected from the surveys, class observations, interviews and weekly meetings revealed four aspects of Japanese student teacher identities: (1) beliefs on foreign language education in and beyond the classroom, (2) self-perceptions of not only language teachers but also future supporters and life helpers, (3) perceptions of teaching Japanese live-online during the COVID-19 pandemic and (4) beliefs on successful language teaching relying on bidirectional cooperation of both teachers and students. The article concludes with a discussion about how the possible directions for future research in terms of the contextual narrative exploration in languages other than English and the integration of both narrative inquiry and positioning analysis methods.

Published: January 2024

Abstract
This paper attempts to explore Slovak EFL learners’ perceptions of the fundamental principles of communicative approach, which has been employed as the primary way of teaching foreign languages for the past five decades. Research participants were formed by 111 Slovak university EFL leaners – teacher trainees (n = 111), who were asked to demonstrate their level of agreement to the statements concerning communicative language teaching by responding to a 5-point Likert scale questionnaire. The calculated means indicate that overall, the research participants are in agreement with the selected principles of CLT as they agreed with 16 out of the 18 chosen statements. However, they appear to be neutral about two aspects of CLT, the use of native language at EFL lessons and discovering and investigating grammatical rules by learners themselves. Arising out of the research results, the conclusions are drawn, and pedagogical implications are discussed.

Published: January 2024

Allelopathy refers to the chemical interactions between plants, where certain species release chemicals which affect the growth, development and survival of neighboring plants. These chemicals, known as allelochemicals, can have also positive or negative side effects on ecosystems, which have potential to interact with climate change. However, the common understanding of the ecological implications of allelopathy and its impact on plant community dynamics, species composition, and biodiversity is limited, with scarce information available on how allelochemicals are produced, released, and affect neighboring plants. The significance of allelopathy for climate change effects on agriculture relates to its interaction with carbon sequestration, nutrient cycling, and soil health and last but not least with greenhouse gas emissions. This review highlights the importance of allelopathy as a vital ecological process for sustainable land management and ecosystem resilience in the face of climate-related challenges.

Authors: Hmood Fadhel Mahmood , Hussain Hayder S. 
Published: January 2024

Manufacturing high-efficiency polymeric materials to moderate fast neutrons by converting them into slow or thermal neutrons. These materials absorb thermal neutrons as well as gamma rays associated with neutrons. Materials of small mass number are used to slow down fast neutrons because neutrons have a high cross-section when they interact with these materials. Materials of high mass number absorb gamma rays. Polyurethane and epoxy were mixed in various ratios to create a blend to serve as neutrons shield, lead (Pb) was then added to the blend at weight percentages of 20%, 30%, 40%, 50%, and 70% to produce a polymer composite.
Polymeric materials reinforced with lead in various ratios were tested to select the best composite. The Polymeric samples were placed between the neutron source and the detector, and changing their thickness from 1 cm to 10 cm in increments of 1 cm. The neutron count rate for five readings was recorded, and the average was taken. As a result, the relationship between count rate and sample thickness was plotted, the half-value thickness of the shield was determined, the relationship between the logarithm ( ) and the thickness was drawn, the removal cross-section ( ) was determined, as well as, the mean free path of the fast neutron, and these were compared for each sample. This work concluded that the sample containing 20% lead with a thickness of 10 cm and a diameter of 4 cm was the best shielding for absorbing fast neutrons.
The removal cross-section (∑R) was analyzed, and the value of half-thickness of the shield, as well as the mean free path of the fast neutron, were determined and compared for each sample.
During the research, it was revealed that a sample containing 20% lead was the best shielding for absorbing fast neutrons.

Authors: Rasheed Maan A. , Saeed Maani A. 
Published: January 2024

The time fractional order differential equations are fundamental tools that are used for modeling neuronal dynamics. These equations are obtained by substituting the time derivative of order where , in the standard equation with the Caputo fractional formula. In this paper, two implicit difference schemes: the linearly Euler implicit and the Crank-Nicolson (CN) finite difference schemes, are employed in solving a one-dimensional time-fractional semilinear equation with Dirichlet boundary conditions. Moreover, the consistency, stability and convergence of the proposed schemes are investigated. We prove that the IEM is unconditionally stable, while CNM is conditionally stable. Furthermore, a comparative study between these two schemes will be conducted via numerical experiments. The efficiency of the proposed schemes in terms of absolute errors, order of accuracy and computing time will be reported and discussed.

Published: January 2024

In order to accurately diagnose Entamoeba spp., this study's major goal was to develop a proof-of-concept method for simultaneously detecting pathogenic and non-pathogenic amoebae using DNA. During amoebiasis, two diagnostic techniques (microscopic inspection and PCR techniques with particular primers) were evaluated. About 100 feces samples from Fallujah individuals who had clinical symptoms were taken. The outcome reveals that only 20 samples have Entamoeba spp. infections. According to this study, the two species had distinct infection percentages. Entamoeba histolytica was the most prevalent infection, at 85%, followed by Entamoeba dispar, which was 15% of all the Entamoeba-positive samples. In addition to studying the morphology and genes of the positive samples, the residential environment, age, and gender were also taken into consideration. It showed the infective patients in the rural area had a higher rate of infection, which was 18%, while the infection in the urban area was less, which was represented by 2%. As for the effect of the age factor, the highest percentage was from children who did not exceed ten years old, which was 10%. The lowest percentage was 2% for people over the age of sixteen (16). According to the gender factor, a different percentage appeared in males than females. The result showed a high infection rate for males, which was estimated at about 16%, but for females it was much less, at only 4%.

Relevance. Improving prognostic criteria to assess the severity of combined chest and abdominal trauma is urgently needed to justify the scope of intensive care in victims of road accidents during acute traumatic illness.Objective. The objective of the study is to improve the results of treatment during acute traumatic illness in combined chest and abdominal trauma after road accidents, as well as to enhance efficiency of prognostic criteria for severity assessment.Methods. A single-center retrospective and prospective controlled clinical study was conducted in 1400 victims who were treated at the N.S. Karpovich Krasnoyarsk Interdistrict Clinical Hospital of Emergency Care Medicine from 2012 to 2022 and were diagnosed with isolated or combined chest and abdominal trauma. To assess the severity of injury and perform triage, the specific method of severity assessment in combined trauma after road traffic accidents was used, which was developed by the research team of the Prof. V.F. Voino-Yasenetsky Krasnoyarsk State Medical University.Results and discussion. A detailed analysis of the indicators applied to patients of different severity showed that mild and moderate chest and abdomen injuries led to changes in hemodynamic parameters within the physiological norm. The injury in question did not cause consciousness or respiratory disorders in victims of road traffic accidents. Severe injuries led to the development of shock and respiratory failure, in combination with depression of consciousness. In order to compare across different condition severity degrees evaluated by physiological indicators, respective medians and dispersion measures were analyzed for each group. The analysis allowed to assess exacerbated severity of condition in our patients. This procedure requires further adjustment to pre-hospital emergency medical care.Conclusion. The performed statistical analysis allowed to assess the efficiency of severity assessment in victims of road accidents in prehospital setting.
