DEMYSTIFYING STUDENT-UNIVERSITY IDENTIFICATION AMONG VIRTUAL TEFL CANDIDATES: THE CASE OF IRAN
Authors: Salimi Esmaeel Ali , Banitalebi Zahra 
Published: April 2023

Student-University Identification (SUI) of virtual students in higher education is one area of identity that receives less attention. This study aimed to explore the SUI of a purposive sample of five virtual students studying Teaching English as a Foreign Language (TEFL) at the Ph.D. level in Iran. Investigating SUI in higher education among virtual TEFL Ph.D. candidates potentially contributes to demystifying a complex relationship of factors, such as cultural experiences, linguistic backgrounds, and online environment challenges. Using phenomenology, the study investigated the identities of the participants by thematically analyzing semi-structured interview data. The findings revealed the participants’ various ways of identifying with a university, the subsequent consequences of identification, and the obstacles preventing them to develop SUI. The findings indicated that several factors at play are unique to doctoral candidates. The faculty prestige, research-based concerns, and nature of online media were identified to be crucial aspects of SUI for the TEFL Ph.D. students. Universities are thus advised to provide appropriate direction for virtual candidates. The study also found that some students perceived a lack of competence in TEFL, which, in turn, acted as a barrier to their SUI. To alleviate this problem, further research needs to identify what is lacking in teacher education university programs and what initiatives are required to improve TEFL students’ professional development and help them become confident English teachers.

Aim. To investigate the relationship between echocardiographic parameters and laboratory immune inflammation signs in patients after coronavirus disease 2019 (COVID-19) pneumonia depending on the left ventricular (LV) involvement according to speckle tracking echocardiography (STE).Material and methods. The study included 216 patients (men, 51,1%, mean age, 50,1±11,1 years). The examination was carried out in patients 3 months after COVID-19 pneumonia. Patients were divided in 3 groups: group I (n=41) — diffuse decrease (≥4 segments the same LV level) of longitudinal strain (LS) according to STE; group II (n=67) — patients with regional decrease (LS reduction ≥3 segments corresponding to systems of the anterior, circumflex or right coronary arteries); group III — patients without visual left ventricle involvement (n=108).Results. There were no significant differences in LV ejection fraction — 68,9±4,1% in group I, 68,5±4,4% in group II and 68,6±4,3 in group III (p=0,934). A decrease in the global longitudinal left ventricle strain was detected significantly more often in groups I and II compared with group III (-17,8±2,0, -18,5±2,0 and -20,8±1,8%, respectively; p<0,001). At the same time, LS depression of LV basal level (-14,9±1,5, -16,8±1,2% and -19,1±1,7%; p<0,001), as well as a decrease in LS of LV inferior-posterior segments in group with diffuse involvement was detected significantly more often than in groups II and III. In addition, we revealed a significant difference in interleukin-6 concentration — 3,1 [2,5;4,0], 3,1 [2,4;3,8] and 2,5 [3,8;1,7] pg/ml, (p=0,033), C-reactive protein — 4,0 [2,2;7,9], 5,7 [3,2;7,9] and 2,4 [1,1;4,7] mg/l, (p<0,001), tumor necrosis factor-a — 5,9±1,9, 6,2±1,9 and 5,2±2,0 pg/ml, (p=0,004) and ferritin — 130,7 [56,5;220,0], 92,2 [26,0;129,4] and 51,0 [23,2;158,9] pg/l, respectively (p=0,025).Conclusion. A relationship was found between diffuse and regional left ventricular involvement according to STE and signs of immune inflammation in patients 3 months after COVID-19 pneumonia.

O presente estudo aborda a relação entre a Alfabetização Midiática e Informacional (AMI) e sua implementação por meio da atuação dos bibliotecários no âmbito das bibliotecas escolares. No contexto atual, no qual os indivíduos necessitam compreender o universo informacional e desenvolver a capacidade de identificar e reconhecer suas necessidades informacionais para a seleção e uso das diversas fontes de informação e para a qualidade na realização da pesquisa e nos resultados alcançados, a biblioteca escolar torna-se protagonista para que ocorram os processos de aprendizagem e de construção de conhecimento. Diante disto, esta pesquisa tem como objetivo verificar se existem estudos em âmbito nacional que relacionem a AMI e a atuação do bibliotecário que trabalha nas bibliotecas escolares. Para tal, realizou-se um levantamento bibliográfico das publicações nacionais que abordam esta temática, em bases de dados abertas, até o final de novembro de 2021. Foi realizada a análise de sete publicações recuperadas nesta busca. A partir do resultado da análise dos dados coletados, foi possível perceber que apesar da necessidade de urgência na sua implantação, o tema AMI ainda é pouco explorado pelos pesquisadores brasileiros e a sua relação com bibliotecários e bibliotecas escolares é ainda menor. Além disso, os estudos ressaltaram que ainda há muito para ser feito em relação ao desenvolvimento de competências informacionais, mas evidenciaram a necessidade da presença e da atuação do bibliotecário, ressaltando o quão imprescindível é o protagonismo deste profissional no contexto educacional e informacional na escola, nos diferentes tipos de bibliotecas e na sociedade.

Authors: Ambekar Prakash 
Published: April 2023

Schizophrenia is a mental disorder characterised by paranoid, hallucination and delirium. The person with such disorder cannot lead a normal life in the society due to his abnormal communication and thought disorder. Hence such disorders are helpful to diagnose the type and severity of disease. Out of 1000 (one thousand) patients 500 were acute schizophrenia and 500 were chronic schizophrenics. Among 1000, 330 were paranoid and 670 were non-paranoid. The disorder of FTD, language, communication disorders in acute, chronic non-paranoid and paranoid schizophrenia were noted. In the comparison of acute and chronic schizophrenic patients – Negative FTD scores positive negative FTD scores, language disorders score was highly significant (p&#60;0.001). In the schizophrenic negative FTD score Negative positive FTD scores, thought disorder score, language disorder scores were highly significant (p&#60;0.001). This study will be helpful to psychiatrist to differentiate acute and chronic schizophrenic patients and treat them efficiently with proper medication so that such patients can lead normal social and family life.

: Iron deficiency anaemia (IDA) is often associated with congenital heart defect (CHD) in children, especially in developing world. Often it remains undiagnosed due to the unaffordability to do costly tests like serum ferritin. We have done this study to know whether simple test like complete hemogram is sufficient to diagnose IDA in a child with CHD. This hospital based observational study was done for a period of one and half year in paediatric ward of a district medical college of eastern India in children up to the age of 12 years with echocardiography confirmed CHD. Blood sample were tested for serum ferritin, mean corpuscular volume (MCV), mean corpuscular hemoglobin and hemoglobin concentration (MCH,MCHC) and red cell distribution width (RDW) to diagnose IDA.: We found IDA in 46 children out of total 100 CHD cases based on serum ferritin level. Out of 46 IDA children, 40 children (87%) had low MCV, 39 children(84.8%) had low MCH, 33 children (71.7%) had low MCHC, 41 children (89.1%) had high RDW and 37children(80.4%) having microcytic hypochromic picture. In logistic regression analysis we found RDW as the independent predictor of IDA. : IDA is fairly common among children with CHD. Simple blood tests of complete hemogram including MCV, MCH, MCHC and RDW can diagnose it effectively where RDW shows the most predictive value in our study. So in resource limited developing countries we may not depend on costly gold standard tests like serum ferritin to diagnose IDA.
Archeologia totalitaryzmów — możliwości i perspektywy badawcze
Authors: Trzciński Maciej 
Published: April 2023

Contemporary methods used by archeology create prospects for a fuller investigation of crimes against peace and humanity and of war crimes. Due to the lack of written sources or the limited scope of information that results from them, attempts can be made to find and interpret material sources directly related to the events under study. The methods used by archeologists can finally effectively verify information already obtained from archival sources.
Today’s archeology extends its reach to the present, and new specializations such as archeology of armed conflicts or archeology of totalitarianisms contribute to a better identification of, among others, the contemporary history of Poland. These specializations are used all over the world in the process of investigating crimes against humanity and accompany ongoing criminal investigations.

Case:
A 76-year-old woman with multiple myeloma and osteoporosis presented with right hip pain and an impending atypical femoral fracture in the setting of chronic bisphosphonate use. After preoperative medical optimization, she was scheduled for prophylactic intramedullary nail fixation. Intraoperatively, the patient experienced episodes of severe bradycardia and asystole associated with intramedullary reaming, which ceased after distal venting of the femur. No additional intraoperative or postoperative complications were encountered, and the patient recovered uneventfully.

Conclusion:
Femoral canal venting may be an appropriate intervention for similar transient dysrhythmias caused by intramedullary reaming.
Nonlinear Calculation of the Reinforced Concrete Road Pavement Slabs of Highways on the Elastic Basis by the Zhemochkin Method
Authors: Kumashov R. V. 
Published: April 2023

A rectangular reinforced concrete slab is considered taking into account its physical nonlinearity on a linearly elastic homogeneous base under the action of a vertical external load. The anisotropy and heterogeneity of the slab are due to the properties of reinforced concrete, as well as the formation of cracks from the action of an arbitrary load during operation. The nonlinear problem was solved by the Zhemochkin method using the iterative algorithm of the Ilyushin elastic solution method. The Ritz method (determining the deflections of a slab with a pinched normal) and the Boussinesq solution (determining the displacements of points on the surface of an elastic half-space) were used to determine the coefficients of the resolving equations of the Zhemochkin method. At the first iteration, the slab was calculated as linearly elastic, orthotropic, and homogeneous; at subsequent iterations, it was calculated as linearly elastic, anisotropic, and inhomogeneous at each Zhemochkin site. The deflections of the middle surface of the slab from a unit force were determined as a series according to the first five particular Clebsch solutions. Experimental and numerical researches have been carried out. The latter – with the help of the MATHEMATICA computer program. The results obtained showed that the proposed calculation method allows one to accurately describe the distribution of settlements and reactive stresses under the slab. Verification of the methodology for static nonlinear calculation of a rectangular reinforced concrete slab, taking into account its physical nonlinearity, was carried out by comparing the results of calculations of maximum settlement and average pressures under the slab, obtained using the proposed methodology, and the results obtained using the layer-by-layer summation method and modern software systems Lira and PLAXIS 3D.

Abstract
The Burgan reservoir is located in North Kuwait was discovered in 1957. First commercial oil production from this multistack sandstone reservoir started back in 1964. Operating under active bottom water drive as well as edge water drive. The primary reservoir in the field is Burgan of Lower Cretaceous age, which contributes the major oil production of the fields.
Burgan reservoir is the second largest reservoir in terms of STOOIP and reserves, producing 30% of daily oil production. Significant amount of historical production came from the lower part of the reservoir where the pattern of water influx is well understood. Most of the historical production and the majority of remaining reserves are in the upper part of the reservoir where the pressure support and water influx are relatively well understood.
Presence of tar was initially detected from cores and produced oil in some of the wells and visual inspection of core material. Tar zone in the Burgan was considered to be structurally controlled and occurred in specific depth window around oil-water contact. Heavy oil has been discovered in basal parts of Burgan sandstone in some of the zones within North Kuwait. Development of Burgan in north Kuwait began in the 1950s with oil recovery since then from Burgan channel sands with few exceptions in the North Kuwait as samples confirmed ultra-heavy oil.
Quantification of Shrinkage-Induced Cracking in Oilwell Cement Sheaths
Authors: Alberdi-Pagola P. , Fischer G. 
Published: April 2023

Summary
Ensuring the zonal isolation of hydrocarbon reservoirs is one of the main tasks of the cement sheath, but the development of cracks and debonding between the interfaces might lead to underground water pollution and leaks of oil and gas to the environment. Restrained shrinkage of the cement sheath is one of the most significant causes of cracking, and an experimental investigation has been conducted to quantify how extensive shrinkage-induced cracking might be due to changes in ambient humidity conditions, confinement levels, and mixture compositions. The presence of lateral confinement due to the presence of shale provided an 80% reduction in the cracked area compared to unconfined specimens, but still radial cracks as wide as 200 µm, microannuli up to 100 µm, and cracked areas of 50 mm2 in a representative well section were observed. Additionally, a reduction in crack widths and potential leak paths was obtained by reinforcing the cement slurry with synthetic fibers. A detailed quantification of shrinkage-induced cracking is reported in this study, providing crack information such as position, width, and orientation as a function of time.

Abstract
Background
Ankle-foot orthoses (AFOs) are extensively used as a primary management method to assist ambulation of children with Cerebral Palsy (CP). However, there are certain barriers that hinder their prescription as well as their use as a mobility device in all kinds of daily-life activities. This exploratory research attempts to further understand the existing limitations of current AFOs to promote a better personalization of new design solutions.

Methods
Stakeholders' (professionals in CP and end-users with CP) perspectives on AFO technology were collected by two online surveys. Respondents evaluated the limitations of current assistive solutions and assessment methods, provided their expectations for a new AFO design, and analyzed the importance of different design features and metrics to enrich the gait performance of these patients in daily-life. Quantitative responses were rated and compared with respect to their perceived importance. Qualitative responses were classified into themes by using content analysis.

Results
130 survey responses from ten countries were analyzed, 94 from professionals and 36 from end-users with CP. The most highly rated design features by both stakeholder groups were the comfort and the ease of putting on and taking off the assistive device. In general, professionals preferred new features to enrich the independence of the patient by improving gait at functional levels. End-users also considered their social acceptance and participation.
Health care professionals reported a lack of confidence concerning decision-making about AFO prescription. To some degree, this may be due to the reported inconsistent understanding of the type of assistance required for each pathological gait. Thus, they indicated that more information about patients' day-to-day walking performance would be beneficial to assess patients' capabilities.

Conclusion
This study emphasizes the importance of developing new approaches to assess and treat CP gait in daily-life situations. The stakeholders' needs and criteria reported here may serve as insights for the design of future assistive devices and for the follow-up monitoring of these patients.

Abstract
Background and Purpose: Resting-state functional MRI (rs-fMRI) studies in Parkinson’s disease (PD) patients with freezing of gait (FOG) have implicated dysfunctional connectivity over multiple resting-state networks. While these findings provided network-specific insights and information related to the aberrant or altered regional functional connectivity, whether these alterations have any effect on topological reorganization in PD-FOG patients is incompletely understood. Understanding the higher-order functional organization, which could be derived from the ‘hub’ and the ‘rich-club’ organization of the functional networks could be crucial to identifying the distinct and unique pattern of the network connectivity associated with PD-FOG.
Methods: In this study, we use rs-fMRI data and graph theoretical approaches to explore the reorganization of resting-state network topology in PD-FOG when compared to those without FOG (PD-nFOG). We also compared the higher-order functional organization derived using the hub and rich-club measures in the functional connectivity networks of these PD-FOG patients to understand whether there is a topological reorganization of these hubs in PD-FOG.
Results: We found that the PD-FOG patients showed a noticeable reorganization of hub regions. Regions that are part of the prefrontal cortex, primary somatosensory, motor, and visuomotor coordination areas showed were some of the regions exhibiting altered hub measures in PD-FOG patients. We also found a significantly altered feeder and local connectivity in PD-FOG.
Conclusions: Overall our findings demonstrate a widespread topological reorganization and disrupted higher-order functional network topology in PD-FOG which may further assist in improving our understanding of functional network disturbances associated with PD-FOG.

Published: April 2023

Abstract
Many trees of high timber value require canopy cover to become established and at present, they are only harvested from native rainforests. Other species require high radiation to establish and can be planted in monospecific stands. The main question was if the canopy generated by a light demanding rainforest species could protect mid-successional timber species from high radiation and extreme temperatures. We evaluated the establishment of Cabralea canjerana under the canopy of Araucaria angustifolia stands. We related growth with the number of neighbors to determine the better positions to plant C. canjerana. In one stand, we measured environmental and physiological traits and we determined that seedling did not suffer light or water stress. C. canjerana plants establishment was successful in stands of different basal areas and trees reached the highest growth with up to two A. angustifolia neighbors within a 5m radius. Therefore, the number of neighbors is a tool to choose the planting location to convert even-aged to uneven-aged mixed stands. In this way, valuable native timber species that requires canopy protection during the first years can be planted outside the rainforest. This is the first report of an uneven-aged mixed plantation of two Atlantic Forest timber species.
