Published: September 2023

The interaction of a solar wind discontinuity with the backstreaming
particles of the Earth’s ion foreshock can generate hot, tenuous plasma
transients such as foreshock bubbles (FB) and hot flow anomalies (HFA).
These transients are known to have strong effects on the magnetosphere,
distorting the magnetopause (MP), either locally during HFAs or globally
during FBs. However, previous studies on the global impact of FBs have
not been able to determine whether the response stems directly from the
transverse scale size of the phenomenon or its fast motion over the
magnetosphere. Here we present the observation of an FB and its impact
on the magnetosphere from different spacecraft scattered over the
dayside magnetosphere. We are able to constrain the size of the
transverse scale of an FB from direct observations to be about 10
$R_\mathrm{E}$. We further suggest that a
combination of this scale and the motion of the FB over the MP is
responsible for the previously reported global response of the dayside
magnetosphere.
Bounce Resonance between Energetic Electrons and Magnetosonic Waves: A Parametric Study
Authors: Gu Shujie , Chen Lunjin
Published: September 2023

Magnetosonic waves are electromagnetic emissions from a few to 100 Hz
primarily confined near the magnetic equator both inside and outside the
plasmasphere.Previous studies proved that MS waves can transport equatorially
mirroring electrons from an equatorial pitch angle of
90$^\circ$ down to lower values by bounce
resonance.But the dependence of bounce resonance effect on wave or background
plasma parameters is still unclear.Here we applied a test particle simulation to investigate electron
transport coefficients, including diffusion and advection coefficients
in energy and pitch angle, due to bounce resonance with MS waves.We investigate five wave field parameters, including wave frequency
width, wave center frequency, latitudinal distribution width, wave
normal angle and root-mean-square of wave magnetic amplitude, and two
background parameters, $L$-shell value and plasma density.We find different transport coefficients peaks resulted by different
bounce resonance harmonics. Higher order harmonic resonances exist, but
the effect of fundamental resonance is much stronger. As the wave center
frequency increases, higher order harmonics start to dominate. With wave
frequency width increasing, the energy range of effective bounce
resonance broadens, but the effect itself weakens.The bounce resonance effect will increase when we decrease the wave
normal angle, or increase the wave amplitude, latitudinal distribution
width, L-shell value, and plasma density.The parametric study will advance our understanding of the favorable
conditions of bounce resonance.
Robust and irreversible impacts of an AMOC collapse on tropical monsoon systems: a multi-model comparison
Authors: Ben-Yami Maya , Good Peter , Jackson Laura C , Crucifix Michel , Hu Aixue , Saenko Oleg A. , Swingedouw Didier , Boers Niklas
Published: September 2023

A collapse of the Atlantic Meridional Overturning Circulation (AMOC)
would have substantial impacts on global precipitation patterns,
especially in the vulnerable tropical monsoon regions. We assess these
impacts using four state-of-the-art climate models with bistable AMOC.
Spatial and seasonal patterns of precipitation change are remarkably
consistent across models. We focus on the South American Monsoon (SAM),
the West African Monsoon (WAM), the Indian Summer Monsoon (ISM) and the
East Asian Summer Monsoon (EASM). Models consistently suggest
substantial disruptions for WAM, ISM and EASM with shorter wet and
longer dry seasons (-29.07\%,-18.76\%
and -3.78\% ensemble mean annual rainfall change,
respectively). Models also agree on changes for the SAM, suggesting
rainfall increases overall, in contrast to previous studies. These are
more pronounced in the southern Amazon (+43.79\%),
accompanied by decreasing dry-season length. Consistently across models,
our results suggest major rearranging of all tropical monsoon systems in
response to an AMOC collapse.

Authors:   Al-Rasafah Health Directorate, Baghdad, Iraq, Issa Elaf , Rasheed Manal ,   of Biochemistry, College of Medicine, University of Baghdad, Iraq
Published: September 2023

Background: Insulin resistance is a major risk factor in the development of cardiovascular diseases and type 2 diabetes mellitus. Some studies concluded that serum lipoproteins levels and hence lipoprotein ratios were altered in patients with insulin resistance. Objective: To identify the possibility of using lipoprotein ratios as markers for insulin resistance. Methods: A cross sectional study conducted in Baghdad (Medical City) and in Maysan (Al Shaheed Al Sadir Teaching Hospital) from February to December 2020. Eighty-three male and 51 female in Coronary Care Unit and Internal Medicine Wards patients were selected in the study group. Results: Lipoprotein ratios were significantly higher in individuals with homeostatic model assessment for insulin resistance (HOMA-IR) ≥2.5 as compared to subjects with HOMA-IR <2.5. There was a statistically significant association between lipoprotein ratios and insulin resistance when HOMA-IR ≥2.5 (P less than 0.05). Fasting insulin correlated significantly with lipoprotein ratios. Conclusion: Serum lipoprotein ratios and the best one is triglyceride/high density lipoprotein cholesterol could be used as markers for insulin resistance. Keywords: Lipoprotein ratios, insulin resistance, diabetes Citation: Issa EF, Rasheed MK.

Recent Research on the Identification, Assessment, and Response to Fraud Risks: Implications for Audit Practice and Topics for Future Research
Authors: Brazel Joseph F. , Carpenter Tina , Gimbar Christine , Jenkins J. Gregory , Jones Keith L.
Published: September 2023

SYNOPSIS

The financial statement auditor’s identification of fraud risk factors, their assessment of fraud risk, and their fraud risk responses are key to the auditor’s consideration of fraud and fraud detection. Given that the last review of research related to the search for fraud during the audit occurred nearly a decade ago, we provide a summary of recent academic research to update and inform practitioners, researchers, standard setters, regulators, and other stakeholders in the financial reporting process. We categorize and summarize findings from recent academic studies that focus on the auditor’s identification, assessment, and responses to fraud risks. Implications for practice are presented for each of these areas, along with topics and questions for future research.

Exploring the Impact of Technology Dominance on Audit Professionalism through Data Analytic-Driven Healthcare Audits
Authors: Koreff Jared , Baudot Lisa , Sutton Steve G.
Published: September 2023

Artificial intelligence (AI)-enabled tools and analytics hold the potential to radically alter audit processes by disseminating centralized audit expertise. We examine this potential in the context of data analytic-driven audits mandated to reduce fraud, waste, and abuse in a government-sponsored healthcare program. To do so, we draw on semistructured interviews with healthcare providers (i.e., auditees) subject to healthcare audits. Our work shows how use of paraprofessional auditors guided by AI-enabled tools and analytics reflects a very different audit environment. Specifically, auditees’ experiences suggest paraprofessional auditors lack specific expertise and credentials to conduct data-driven audits, apply judgment in deference to technology, and disregard the impact of AI-driven decisions on the public interest. Such experiences raise potential concerns for all audits over unbridled use of AI-enabled tools and analytics by novice-level auditors/paraprofessionals, but even more for audits conducted in contexts where adherence to professional norms is essential to minimizing public interest consequences.

How Do Individual Analyst Characteristics Affect Analyst Performance?
Authors: Bratten Brian , Larocque Stephannie
Published: September 2023

Motivated by research from the late 1990s and early 2000s, researchers often examine analyst performance as a function of individual analyst characteristics using variables representing analysts’ experience, busyness, and resources. Studies make different choices for variable construction and fixed effects, sometimes with varying results, suggesting there is no standard approach to evaluating the effect of analyst characteristics. We reproduce analyses from two early studies (Clement (1999) and Clement and Tse (2003)) and extend these analyses to a more recent sample period and across different methodological approaches and alternative analyst performance measures. We provide robust evidence that analyst experience is positively associated with earnings forecast accuracy but that associations for analyst resources and busyness are sensitive to variable measurement and fixed effect choices. Our results can inform accounting and finance scholars examining analyst performance as they consider which analyst characteristics to include and how to test the robustness of their findings.
Customer Satisfaction and Internal Control
Authors: Chen Ting , Liu Xiaotao Kelvin , Wan Chi , Wang Yakun
Published: September 2023

We investigate whether firms’ ineffective internal control over financial reporting is associated with customer satisfaction, measured by product ratings on Amazon.com. Internal control weaknesses will likely corrupt the information environment, compromise coordination, and divert corporate resources to address the control deficiencies. Using a large sample of product rating data from Amazon.com, we find robust and consistent evidence that internal control weaknesses are negatively associated with customer satisfaction. Furthermore, the negative association is more pronounced for environment-level (versus other) internal control weaknesses, noncore (versus core) products, and more (versus less) operationally complex firms. Our findings provide initial evidence that ineffective internal control compromises customer satisfaction.

Published: September 2023

Bu çalışmada, piston oyukları düşük ısı iletim katsayısına sahip bir malzemeyle kaplanmış direkt püskürtmeli bir dizel motorun yanma odası ısı transfer karakteristikleri incelenmiştir. Testler, sabit devirde ve dört farklı motor yükünde yapılmıştır. Piston oyukları plazma sprey yöntemiyle itriya stabilize zirkonya maddesi ile kaplanmıştır. Isı taşınım katsayısı hesaplanmasında dizel motorlar için literatürde sıklıkla kullanılan Hohenberg, Eichelberg ve Woschni modelleri esas alınmıştır. Başlıca ısı geçişi parametreleri olarak ısı transfer katsayısı, ısı akısı, birim krank açısında toplam ısı çıkışı ve ısı geçişi ele alınmıştır. Yapılan çalışma sonucunda; artan motor yükü ve piston kaplama uygulamasıyla birlikte yanma odasında ısı taşınım katsayısının, ısı akısının, toplam ısı çıkışının ve ısı akısının önemli oranda arttığı gözlenmiştir. Sıkıştırma periyodunda, Hohenberg modelinin genel olarak daha yüksek ısı transfer oranı değerleri verdiği buna karşılık Woschni modelinin daha düşük ısı transfer oranı değerleri verdiği tespit edilmiştir. Isı geçişi parametreleri düşük yükte Woschni modeliyle en düşük değerdeyken en yüksek yükte maksimum değerlere ulaşmıştır. En yüksek yükte her iki motorda da toplam ısı çıkışı değerleri kullanılan tüm modellerle birbirine oldukça yakın bulunmuştur.

Published: September 2023

An efficient quality evaluation method is crucial for the applications of high-quality microhole arrays drilled with ultrafast lasers. The vision-based feature extraction was used as a data acquisition method to evaluate the drilling quality in terms of the geometric quality of the hole shape. However, the morphological features such as the recast layer, microcracks, and debris on the surface are difficult to consider in the quality evaluation since simultaneous recognition of multiple features remains challenging. Herein, we successfully recognized and extracted multiple features by deep learning, thus achieving the quality evaluation of microhole arrays in terms of both geometrical and surface qualities. Microhole arrays of various sizes and surface quality are fabricated on copper, stainless steel, titanium, and glass using different processing parameters. Then, the images of the microhole arrays are prepared as the dataset to train the deep learning network by labeling the typical features of microholes. The well-trained deep learning network has efficient and powerful recognition ability. Typical features such as the hole profile, recast layer, microcracks, and debris can be recognized and extracted simultaneously; thereby the geometric and surface quality of the microhole are obtained. We also demonstrate the implementation of the method with a fast quality evaluation of an array of 2300 microholes based on a statistical approach. The methods presented here extend the quality evaluation of microhole arrays by considering both geometric and surface qualities and can also be applied to quality monitoring in other ultrafast laser micromachining.

Published: September 2023

This research aims to improve students’ writing skills at SMP Negeri 15 Bandar Lampung by using the Clustering technique. The participants of this research were the students in eighth grade. The total numbers of students were 33 students. Employing classroom action research, this study was carried out for two cycles at VIIIA. The main emphasis of this study was the improvement of students' learning activities and writing skills. In cycle 1, students were less engaged, less self-assured, and the classroom environment was still out of control. The cycle one learning activities' mean score for students was 6.53, which had a subpar predicate. Cycle 2 revealed an improvement in the students. They were more engaged and self-assured, and the environment in the classroom was entertaining and under control. The students' cycle two learning activities had an average score of 7.50 and a favourable predicate. Additionally, in cycle one writing test had a mean score of 64.81, with 16 students or 48.48% passing the goal. It indicates that students' writing abilities have improved. The writing test for students in cycle 2 had a mean score of 77.39; 27 students, or 81.82%, passed the target. From the data shown, it could be concluded that classroom action research using the Clustering technique can improve students' learning activities and writing skills.

Wpływ laserowej korekcji starczowzroczności metodą Presbyond® Laser Blended Vision (LBV) na poczucie kontrastu
Authors: Wierzbowska Joanna , Pniakowska Zofia
Published: September 2023

Metoda Presbyond® Laser Blended Vision (LBV), oparta na technice zabiegu FemtoLASIK, jest obecnie najczęściej wykonywaną laserową procedurą refrakcyjną mającą za cel korekcję starczowzroczności. Metoda ta polega na nieliniowej asferycznej ablacji rogówki i kontrolowanym wyindukowaniu aberracji sferycznych w obojgu oczach oraz wytworzeniu mikromonowizji od -0,75 do -1,50 D w oku niedominującym. W artykule przedstawiono wyniki opublikowanych prac analizujących wpływ laserowej korekcji starczowzroczności metodą Presbyond® LBV na poczucie kontrastu. Dotychczasowe badania wskazują, że zabieg Presbyond® LBV nie wpływa istotnie na czułość na kontrast.
Rotational stability of the enVista® toric lens compared to other commonly implanted toric intraocular lenses – a literature review
Authors: Liberski Sławomir , Dmitriew Andrzej , Kocięcki Jarosław
Published: September 2023

Preoperative corneal astigmatism higher than 1 D is present in up to 30–47% of eyes with cataracts. Proper correction of astigmatism, apart from the adequately determined spherical power of the artificial intraocular lens (IOL), is the main factor ensuring the desired result of the procedure manifested as postoperative spectacle’s independence, visual function, and as a result – patient satisfaction. Toric IOL implantation allows simultaneous cataract removal and correction of corneal astigmatism during one surgical procedure. Since the introduction of toric IOLs, more rotationally stable lenses allowing for better refractive performance have been introduced to clinical practice. EnVista® is an acrylic toric IOL (enVista® MX60T; Bausch and Lomb Inc., Rochester, NY, USA), which was introduced in 2018, and currently is one of the most used toric IOLs in clinical practice worldwide. Rotational stability, apart from adequately selected spherical and toric IOL equivalents, is the most crucial parameter determining the benefits of using a toric lens because it is estimated that for every 1° of rotation of the toric IOL from the target axis, the correction of astigmatism is reduced by 3.5%; therefore a significant change of position in the postoperative period may require another surgical intervention. In this review, based on published research, we summarized the rotational stability of the enVista® lens compared to the other toric IOLs available on the market.
Practical patient care appraisals with use of new potassium binders in heart failure and chronic kidney diseases
Authors: Senni Michele , Sciatti Edoardo , Bussalino Elisabetta , D’Elia Emilia , Ravera Maura , Paoletti Ernesto
Published: September 2023

Hyperkalaemia is a life-threatening condition leading to significant morbidity and mortality. It is common in heart failure and in chronic kidney disease (CKD) patients due to the diseases themselves, which often coexist, the high co-presence of diabetes, the fluctuations in renal function, and the use of some drugs [i.e. renin-angiotensin-aldosterone system (RAAS) inhibitors]. Hyperkalaemia limits their administration or uptitration, thus impacting on mortality. New K+ binders, namely patiromer and sodium zirconium cyclosilicate (ZS-9), are an intriguing option to manage hyperkalaemia in heart failure and/or CKD patients, both to reduce its fatal effects and to let clinicians uptitrate RAAS inhibition. Even if their real impact on strong outcomes is still to be determined, we hereby provide a practical approach to favour their use in routine clinical practice in order to gain the correct confidence and provide an additive tool to heart failure and CKD patients’ wellbeing. New trials are welcome to fill the gap in knowledge.

Die Differenz im Ursprung - Die Entwicklung des Genealogiebegriffs in Gilles Deleuzes Nietzsche et la philosophie
Authors: Valladão Silva Gabriel
Published: September 2023

Dass Nietzsche den Begriff der Genealogie in die Philosophie eingeführt hat, ist keineswegs verbrieft. War der Begriff für Nietzsche selbst so wesentlich, wie seine spätere Rezeption es nahelegt? Diese rezeptionsgeschichtliche Untersuchung zeigt, wie der Begriff «Genealogie» in Gilles Deleuzes 1962 erschienenem Werk Nietzsche et la philosophie entstanden ist. Der Autor erhellt die philosophiehistorischen Zusammenhänge, die einerseits Deleuzes Entscheidung, Nietzsche im Zeichen des Genealogiebegriffs zu interpretieren, verständlich machen und die andererseits die außerordentliche Wirkung dieses Werks erklären. Er geht den Quellen nach, die Deleuzes Auffassung der Philosophiegeschichte sowie seiner Perspektive auf Nietzsches Philosophie insbesondere zugrunde liegen, und rekonstruiert die intellektuelle Atmosphäre, in der Nietzsche et la philosophie erschienen ist.

CASE REPORT: KLIPPEL-TRENAUNAY SYNDROME
Authors: Santos Nathalya , Silva Adriana , Rodrigues Vitor , Vargas Jacqueline , Otilia-Fischer Emelie
Published: September 2023

INTRODUCTION: Klippel-Trenaunay syndrome (KTS) is a rare congenital disease, characterized by the triad: capillary malformations that manifest as port wine stain, typically venous varicosities, bone and soft tissue hypertrophy. CASE REPORT: LFRR, term newborn weighing 3360g, male, cesarean delivery due to imminent eclampsia (G3P2C0). Apgar score 9/9 with physical examination showing left lower limb with port wine stain, increased volume and diffuse violaceous lesions extending from the toes to the buttocks, palpable and symmetrical peripheral pulses. DISCUSSION: KTS management does not have a wellestablished consensus, and conservative treatment can be performed using non-invasive measures (elastic or non-elastic compressive stockings) associated or not with psychological support, elevation of the affected limb and physiotherapy. Active conducts such as sclerotherapy can be used in small areas, as well as the use of laser therapy on port wine stains and ulcerations. Sirolimus may be a promising therapeutic option for the management of venous malformations, including KTS, leading to an improvement in symptoms such as pain and a decrease in the size of the lesions. CONCLUSION: KTS, as a rare syndrome, has scarce literature. The main management is based on the use of conservative therapies, others related to the complications presented and now begins the phase of using off-label drugs (Sirolimus) that slow down the progression of the disease.
Empaques vs Bioempaques para alimentos: Una comparación a nivel técnica, comercial y normativa
Authors: Acosta Medina Julieth Katherin , Contreras Pacheco Orlando Enrique , Pedraza Avella Aura Cecilia
Published: September 2023

En la era contemporánea, la industria alimenticia está llamada a garantizar que sus productos mantengan buena calidad, siendo su empaque uno de los retos más evidentes. Tradicionalmente los materiales de envasado alimenticio correspondían a derivados del petróleo, pero en los últimos años han surgido biomateriales que pueden cumplir estas funciones, y es importante conocer las superioridades e inferioridades de estos sobre los empaques convencionales. Por ello, en este estudio, se llevó a cabo un análisis comparativo exhaustivo entre los empaques tradicionales y los bioempaques para alimentos, en términos de mercado, aspectos técnicos y normatividad. Se recopiló información de bases de datos especializadas y se analizaron 59 fichas técnicas de empaques convencionales y 28 fichas técnicas de bioempaques. Los resultados revelaron que ciertos bioempaques, como la celulosa, el ácido poliglicólico y el polihidroxibutirato, son alternativas excelentes para el envasado de alimentos, siendo eficaces en situaciones en las que se requiere resistencia a la humedad y la oxidación, o la capacidad de soportar altas temperaturas durante la producción y el almacenamiento de los productos. También se encontró que el mercado de bioempaques es el que experimenta un mayor crecimiento debido a la creciente demanda de envases sostenibles, las regulaciones gubernamentales en contra de los plásticos de un solo uso y las tendencias de consumo de los consumidores. En base a estos hallazgos, se recomienda a la industria alimenticia considerar el uso de bioempaques como una solución viable y prometedora para mejorar la calidad y la conservación de sus productos, al tiempo que se cumplen con los requisitos ambientales y las preferencias de los consumidores.
High Performance of ZnO/PANI Nanocomposites for Supercapacitors Applications
Authors: A. Mohammed Sarwa , R. Ahmed Adnan , M. Ibrahim Isam
Published: September 2023

One of the goals of current technology is to miniaturize electronic, operational, sensing and optical devices and their components. Thus, nanotechnology is an advanced technology favored by the scientific and industrial communities for its ability to exploit the unique properties of nanomaterials on a large scale. This study examined the polyaniline (PANI) solution with (ZnO) in different volume ratios through depositing (PANI: ZnO) on glass and silicon substrates. Alkalis were prepared and cleaned in a specific method and kept in tanks until they were used in a precipitation process using distillation casting techniques, which were carried out on silicon. The results showed that the as-prepared material has the characteristic of electrochemical performance. The synthesis test showed the consistency and compatibility among the materials used in the study with a maximum elapse time of (7.72 sec) and a maximum voltage of (0.203 V). The highest intensity for ZnO was at (36.3008°) with a Miller coefficient of (101) and for PANI was at (25°) with a Miller coefficient of (200). The X-ray diffraction results showed a successful matching procedure. When ZnO and PANI were mixed, the Miller coefficient (100) at (35o) angle provided the highest intensity. This proved that the materials used in the precipitation process were compatible. As for scanning electron microscopy, the results showed homogeneity and diffusion in the prepared material, where the grain volume decreased with the increase in ZnO. The best mixing ratio was (5:5) of (ZnO/PANI).

Acute myeloid leukemia is a second type of leukemia and has more effect on elder patients than adult. This research's objective was to measure the serum levels of ceruloplasmin (CP), ferritin (FR), vitamin B12 (VitB12), folic acid (FA), zinc (Zn), copper (Cu), and iron (Fe) in acute myeloid leukemic patients (AML) (before and after taking chemotherapy) and healthy control groups. In this study, about (160) blood samples (males and females) were collected from acute myeloid leukemic patients in Erbil’s Nanakali hospital and they were separated into four groups: Group 1 (G1) including (40) Apparently healthy control group, Group 2 (G2) include (40) acute myeloid leukemic patients before taking chemotherapy (new cases), Group 3 (G3) include (40) acute myeloid leukemia patients taking chemotherapy for one cycle, and Group 4 (G4) include (40) acute myeloid leukemic patients with taking chemotherapy for more than one cycle. The outcomes display a significant increase in serum concentration of ceruloplasmin, ferritin, vitamin B12, and iron in all patient groups when compared with control groups. While the serum concentration of folic acid, zinc, and copper decreased in all patient groups when compared with the healthy control group. In addition, the correlation analysis displays that there was a significant positive correlation between ceruloplasmin with ferritin, vitamin B12, and iron, on another hand have a non-significant negative correlation between ceruloplasmin with folic acid, zinc, and copper. According to the present study, there was a direct correlation between AML patients with the serum levels of CP, FR, VitB12, FA, Zn, Cu, and Fe. A high area under the curve of our data suggests that testing for (CP, FR, VitB12, FA, Cu, and Fe) could be helpful to detect AML. However, zinc is not a good biomarker for detecting AML patients.

A New Scaled Three-Term Conjugate Gradient Algorithms For Unconstrained Optimization
Authors: Abdullah Zeyad M. , Asker Songul A.
Published: September 2023

Since optimization problems are getting more complicated, new ways to solve them must be thought of, or existing methods must be improved. In this research, we expand the different parameters of the three-term conjugate gradient method to work out unconstrained optimization problems. Our new CG approach meets the conditions of sufficient descent, and global convergence. In addition, we describe some numerical results that imply comparisons to relevant methodologies in the existing research literature.

The induced plasma technique was used in the current investigation to create lead oxide nanoparticles from bulk structures at various bombardment periods (4,6,8,10) min. The process will be carried out in the presence of argon gas that flows at a constant rate (3 L/sec). These nanoparticles were created as thin layers on various thicknesses of glass substrates prepared at different times of shelling”. After that, they were analyzed with an x-ray spectrum, scanning electron microscope (SEM), atomic force microscope (AFM) and UV-visible spectrophotometer. Where the optical characteristics and constants were examined, the energy gap of the films varied with bombardment periods from  2.1 ~1.98eV. The SEM and AFM images clearly display a structure that varies with bombardment duration due to the fluctuation in the diameter of the nanoparticles. Finally, the layers' entire amorphous nature is revealed by the x-ray spectrum.

Introduction: Down syndrome is a congenital disorder caused by a total or partial trisomy of chromosome 21 and is considered the most common genetic cause of congenital malformations and intellectual disability. The objective of this study was to describe the cytogenetic alterations of patients with Down syndrome and their relationship with maternal age. Methods: Cross-sectional, descriptive-analytical study. 436 patients with Down syndrome admitted to the Instituto Nacional de Salud del Niño during the 2017-2019 period were included. The variables analyzed were: cytogenetic diagnosis and maternal age. Results: It was found that 99,3% (n=433) of patients presented some type of cytogenetic alteration and three patients presented a normal karyotype. The age of the patients at the time of sampling was between 0,03 and 17 years, the male/female ratio was 1.2:1. The most frequent cytogenetic alteration was free trisomy 21 (94,7%), followed by Robertsonian translocation (n=16) and mosaicism (n=6). In the case of maternal age, a median of 37 years was found (range: 13-47). Conclusions: Free trisomy 21 is the most common cytogenetic condition in Down syndrome; however, the Robertsonian translocation and mosaicisms were more frequent in patients whose mothers were les than 35 years old, suggesting that there are other risk factors than advanced maternal age in this group.

Objective: To determine if the use of inhaled corticosteroids is a risk factor for community-acquired pneumonia in patients with Chronic Obstructive Pulmonary Disease at the Víctor Lazarte Echegaray Hospital during the period 2017-2020. Methods: The study was analytical, observational, retrospective of cases and unmatched controls in a ratio of 4:, with a population of 405 subjects from whom 81 cases and 324 controls were selected, who met the selection criteria. A non-probabilistic sampling was carried out. The variables, use of inhaled corticosteroids, patients with community-acquired pneumonia, age, sex, malnutrition and smoking were included. The association was measured using Pearson's non-parametric Chi-square test and Fisher's exact test at lower frequencies less than 5. The bivariate and multivariate analysis was performed using multiple logistic regression with statistical significance (p value <0.05). The study statistician was the odds ratio (OR). Results: Through the multivariate analysis of the variables under study, no relationship was found between the use of inhaled corticosteroids and patients with community-acquired pneumonia (OR= 1.17; 95%CI: 0.48-2.99 and p value=0.737). It was observed that only age can be considered as a risk factor in view of its significance (OR=1.09; 95%CI: 1.06-1.12 and p value<0.001), while the variables sex, malnutrition, and smoking proved not to be significant ( p> 0.05). Conclusions: The use of inhaled corticosteroids is not a risk factor for community-acquired pneumonia in patients with chronic obstructive pulmonary disease.

Linguistic Means of Expressing Epistemic Modality in an English-language Scientific Text
Authors: Nurieva N. S. , Razheva E. S.
Published: September 2023

Modality is a complex grammatical and functional-semantic category which is reflected in various types of discourse. The relevance of studying epistemic modality, reflecting the author’s knowledge of the reported information and his/her attitude to it from the point of view of its reliability, is determined by the necessity to analyze the linguistic features of its expression in a scientific text.

   The aim of the paper is to study morphological, lexical-syntactical and lexical means of expressing modality and to identify their pragmatic functions in English-language texts concerned with engineering.

   The study of the linguistic component in a scientific text will help foreign researchers present their scientific works in accordance with the authentic features of English. This determines the theoretical significance of studying the author’s means of expressing epistemic modality as a method for reasoning their scientific propositions, interacting with the target reader and expressing academic responsibility. The study of theoretical works by foreign and Russian scientists has shown that epistemic modality of a scientific text implements mainly the properties of the author’s subjective approach. However, unlike other types of discourse, the modality of a scientific text identifies a certain degree of objectivity in the author’s approach since it is characterized by the assessment of the reported information in terms of its reliability/unreliability. The given study assumes that the category of modality of any text, including a scientific one, is difficult to analyze statistically. It is known that the expression of the English text modality is characterized by imperceptible “transitions” between different levels of its implementation. Therefore, the paper considers some linguistic means at the morphological, lexical-syntactical and lexical levels. They include the verbal category of the imperative, subjunctive and presumptive types of mood, infinitive constructions, modal verbs and modal words of various parts of speech with the seme “expectation/assumption”. The article underlines an additional pragmatic aspect of modality means in an English-language scientific text concerned with the need for soft persuasion of the professional community to accept the information presented.
