Authors: Huang Wenke , Deng Weilin , Hu Bei , Huang Chongqiu , Zeng Xingbin
Published: January 2023

Asphalt-aggregate interfacial adhesion performance plays an important role in the durability and stability of asphalt mixtures. The determination of the adhesion between the surface minerals of aggregate and the asphalt binder, to quickly and quantitatively evaluate the interface performance between the aggregate and the asphalt binder, has attracted extensive attention. In this article, hyperspectral imaging technology combined with a TESCAN integrated mineral analyzer (TIMA) was proposed to determine the surface mineral compositions of pavement aggregate, and the mineral classification quality and performance of the proposed method were assessed. The test results showed that the endmember spectra of the different minerals could be established based on the TIMA results. The mapping results obtained by the US Geological Survey library were far inferior to those obtained using the proposed method, and the mineral distribution texture of the granite and diabase obtained by the proposed method were in good agreement with those of digital images. The proportion of unclassified minerals of granite was only 3–8 % of the total content, which is an acceptable range for engineering applications, and the three main minerals in diabase could also be effectively identified. The proposed method can be a quick and accurate way to obtain the types and contents of minerals on an aggregate surface from the mineral hyperspectral spectra of aggregates from the same mine or area.

Taenia solium taeniasis/cysticercosis is an important global food-borne infectious disease transmitted between humans and pigs. According to both national surveys and field investigations, the prevalence of the disease in China has significantly decreased in recent decades. The primary disease control measures are health education and promotion, meat inspection, and chemotherapy. Other factors that influence or fundamentally affect human and pig T. solium taeniasis/cysticercosis have been identified, such as pig farming patterns shift and a revolution in sanitary toilets, which block T. solium transmission routes. Pig farming practices have shifted from backyard to large-scale intensive farming, thus decreasing pig contact with, and consumption of, human excreta. The increased in the use of sanitary toilets has facilitated hygiene by preventing of human excreta from contacting humans, or polluting the environment, feed, or water. The occurrence of human T. solium infections has markedly decreased as a result of these social changes. The objective of this review is to describe the ecological determinants of the cysticercosis decline in China.

Authors: Ogunbode Timothy O
Published: January 2023

The contributions of all and sundry are salient to the global efforts in mitigating climate change-associated challenges. While global communities are rallying round to discuss the effects of climate change with millions of dollars being sunk into the process of mitigation, it is so unfortunate that the perceptions about the climate change menace is quite unwelcomed. The implications of such attitude manifest in the attitude towards the causative actions being noticed which seemed to be unabated, most especially in developing countries. This brief communication examines the case of local perception on climate change in Nigeria and the way forward. Education and enlightenment on the reality of climate change and its manifestations are desirable at both local and international levels by relevant stakeholders.

Published: January 2023

Pelvic organ prolapse is an urgent problem of modern gynecology, due to its wide distribution. The aim of the study was to study the frequency, structure and significance of POP risk factors among women of different ages. A prospective examination of 157 women was carried out, including 127 patients (main group) with gynecological pathology by a continuous method and 30 women with normal reproductive function without PTO (control group).The results showed that genital prolapse was detected in 56.7% of women with gynecological pathology, and a parallel increase in the frequency and age of women. The structure of PTO was dominated by prolapse of the walls and vaults of the vagina, cystocele, rectocele, prolapse of the uterine body and its combined forms. Such risk factors as: high parity (65.3%), short intergenetic interval (87.5%), rapid and rapid labor (16.1%) and labor with a large fetus (28.1%), operative vaginal delivery (11.3%), soft tissue injuries of the birth canal (26.4%), andoverweight (45.8%), obesity (37.5%),heavy physical labor (51.4%) and constipation (47.2%). Thus, rThe development of genital prolapse occurs under the influence of various adversefactors thatdetermines the need for measures aimed at the timely detection and correction of risk factors, which is possible with an increase in the role of preventive medicine.

Published: January 2023

Clinical research on neonatal resuscitation has accelerated over recent decades. However, an important methodologic limitation is that there are no standardized definitions or reporting guidelines for neonatal resuscitation clinical studies. To address this, the International Liaison Committee on Resuscitation Neonatal Life Support Task Force established a working group to develop the first Utstein-style reporting guideline for neonatal resuscitation. The working group modeled this approach on previous Utstein-style guidelines for other populations. This reporting guideline focuses on resuscitation of newborns immediately after birth for respiratory failure, bradycardia, severe bradycardia, or cardiac arrest. We identified 7 relevant domains: setting, patient, antepartum, birth/preresuscitation, resuscitation process, postresuscitation process, and outcomes. Within each domain, relevant data elements were identified as core versus supplemental. Core data elements should be collected and reported for all neonatal resuscitation studies, while supplemental data elements may be collected and reported using standard definitions when possible. The Neonatal Utstein template includes both core and supplemental elements across the 7 domains, and the associated Data Table provides detailed information and reporting standards for each data element. The Neonatal Utstein reporting guideline is anticipated to assist investigators engaged in neonatal resuscitation research by standardizing data definitions. The guideline will facilitate data pooling in meta-analyses, enhancing the strength of neonatal resuscitation treatment recommendations and subsequent guidelines.

Authors: Kumar Luitel Keshar , Thirukumaran V. , Homnath Luitel
Published: January 2023

Estimation of soil overburden and depth of competent strata for construction of infrastructures in hilly terrain is a challenging job for engineers. Modern technologies like Electrical Resistivity Survey (ERS) techniques with site geological mapping have been carried out at the ridge area near Palace, Gangtok. Two independent 2D-electrical resistivity surveys profile sections using hybrid Schlumberger-Wenner method were conducted along the ridge line trending in the North-South direction. The ERS profile sections were taken on both the slopes of the ridge along its eastern and western flanks. With the collective information from field and geo-technical data, a comparatively stable slope has been identified with respect to geological conditions in the present work, which focuses on the vulnerable slope failure with respect to slope direction, local geological condition, depth of competent strata, thickness of soil overburden, water saturation zones and resistivity of the materials. Diamond core drilling of 15meters each was carried out at both the flanks of the slope to understand the sub-surface strata and correlate it with resistivity data generated by ERS survey. The result indicates that Sandy/silty soil with flakes of mica having resistivity of 107 ohm-m and weathered mica schist having resistivity more than 300 ohm-m in the present study area. Geological mapping in 1:3000 scale was carried in the area demarcation with various litho-units and rock type. The area is characterized by medium grade metamorphic rock sequence represented in the area by mica schist having dip of foliations towards NE direction and three sets of joint planes. The geometry of the rock orientation and slope direction plays a vital role for determining the overall stability condition of the area. The present study will provide technical input for structural engineers to design the structures in such geological conditions. Further, the thickness of overburden estimated from ERS has been validated by drilling data.

Published: January 2023

For a long time, the tourism industry was considered one of the economy’s lead- ing and most progressive sectors, characterized by an advanced scale of development. The situation was changed fundamentally by the COVID-19 pandemic, which caused significant losses at the global level, not only for tourism but also for all sectors of the economy and society. In this regard, the provision of this article identifies the nature of the impact of the COVID-19 pandemic on tourism in a particular country in the European region using cluster analysis. In the first stage of this work, a detailed literature review on the existence of such a connection was carried out with the help of bibliometric analysis. The authors used the results published in Scopus and Web of Science databases for the keywords «tourism», and «Covid-19» and analyzed the growth dynamics in their number and citations, belonging to the research area and the spread of geography. Building a bibliometric map of keywords based on their joint placement in the VOSviewer software complex deepened findings. It made it possible to form 10 clusters, each of which covers scientific works on various forms of the impact of the COVID-19 pandemic on tourism (for example, behavioral, marketing, economic, environmental, psychological aspects, etc.). In the second stage, an analytical review was conducted, which showed a significant drop in the absolute and apparent contribution of travel and tourism to GDP worldwide in 2020 and 2021 worsened with the pandemic level, and an increase in the dynamics of key indicators of the tourism industry in the world and across all UNWTO regions (especially Asia & Pacific). In the last step, a hierarchical agglomerative cluster analysis (with Ward’s method) was carried out for the countries of the European region (45 countries) based on indicators of the number of COVID-19 cases in the country (cumulative and new), vaccination of the population, the presence of restrictions on tourism, international tourist arrivals, and receipts, collection of tourism in exports. All indicators for analyzing the collected state are provided as of July 30, 2022, using the Stata SE 12 software complex. The construction of a dendrogram and the use of Calins- ki-Harabasz and Duda-Hart stopping rules made it possible to decide on the presence of 3 clusters that meet the conditions of this study and are characterized by different levels of adaptability to post-pandemic functioning and recovery direction.
Chinese Buddhism Today: Conservatism, Modernism, Syncretism and Enjoying Life on the Buddha’s Light Mountain
Authors: Yao Yu-Shuang , Gombrich Richard
Published: January 2023

Fo Guang Shan, “Buddha’s Light Mountain”, is a Buddhist movement founded in Taiwan in 1967 and led by the Ven Hsing Yun (b.1927), who had fled to Taiwan from mainland China in 1949. It stands in the Chinese tradition of Mahāyāna Buddhism and more specifically is a form of Buddhism which in English is usually referred to as “Humanistic Buddhism” or as “engaged Buddhism”. Humanistic Buddhism owes its origin to the Chinese monk Tai Xu (1890-1947). He found the Buddhism which surrounded him in China dreary and moribund, preoccupied with rituals for the dead, and offering nothing to help or guide people living in the world outside monasteries. His determination to reverse this decay centred on the idea that it was the vocation of a Mahayana Buddhist to do good to others, finding their own spiritual benefit in benefitting society. Hsing Yun has been a devoted disciple of Tai Xu. It is telling that he founded a seminary before he founded a monastery, and has laid huge emphasis on education. As the sub-title of this book indicates, in order to make Buddhism widely attractive and relevant he has incorporated every influence available. Gifted with a benign personality, he has turned his seemingly boundless energy and prodigious versatility to creating an institution which presents Buddhism as potentially a source for benefitting society through making life enjoyable. This book hopes to convey the movement’s ethos primarily by focusing on his views and activities.
What the Buddha Thought
Authors: Gombrich Richard
Published: January 2023

In What the Buddha Thought, Richard Gombrich argues that the Buddha was one of the most brilliant and original thinkers of all time. Intended to serve as an introduction to the Buddha’s thought, and hence even to Buddhism itself, the book also has larger aims: it argues that we can know far more about the Buddha than it is fashionable among scholars to admit, and that his thought has a greater coherence than is usually recognised. It contains much new material. Interpreters both ancient and modern have taken little account of the historical context of the Buddha’s teachings; but by relating them to early brahminical texts, and also to ancient Jainism, Gombrich gives a much richer picture of the Buddha’s meaning, especially when his satire and irony are appreciated. Incidentally, since many of the Buddha’s allusions can only be traced in the Pali versions of surviving texts, the book establishes the importance of the Pali Canon as evidence. The book contains much new material. The author stresses the Buddha’s capacity for abstraction: though he made extensive use of metaphor, he did not found his arguments upon it, as earlier thinkers had done. He ethicized and radically reinterpreted older ideas of karma (human action) and rebirth. Similarly, building on older texts, he argued for the fundamental importance of love and compassion, and analysed fire as a process which could stand as a model for every component of conscious experience. Morally, the Buddha’s theory of karma provided a principle of individuation and asserted each individual’s responsibility for his own destiny. To make the book completely accessible to the general reader, the author provides an introductory section of ‘Background Information,’ for easy reference.

Multiscale micromechanics modeling of plant fibers: upscaling of stiffness and elastic limits from cellulose nanofibrils to technical fibers
Authors: Königsberger Markus , Lukacevic Markus , Füssl Josef
Published: January 2023

The mechanical properties of natural fibers, as used to produce sustainable biocomposites, vary significantly—both among different plant species and also within a single species. All plants, however, share a common microstructural fingerprint. They are built up by only a handful of constituents, most importantly cellulose. Through continuum micromechanics multiscale modeling, the mechanical behavior of cellulose nanofibrils is herein upscaled to the technical fiber level, considering 26 different commonly used plants. Model-predicted stiffness and elastic limit bounds, respectively, frame published experimental ones. This validates the model and corroborates that plant-specific physicochemical properties, such as microfibril angle and cellulose content, govern the mechanical fiber performance.
Understanding building information modelling and its use in the Chinese construction industry
Authors: Liu Zhaoqiu , Zhang Fei
Published: January 2023

Building information modelling (BIM) is both a digital modelling method and information integration platform for interoperability in the construction industry. This paper reviews the concepts and features of BIM along with its different meanings, historical evolution and data exchange standards. It then analyses its application in the Chinese construction industry, with examples of recent major projects. It concludes that many civil engineers are still unable to use BIM to its full potential due to implementation complexity and the industry’s fragmented production structure.
Global Diffusion of Montessori Schools

Published: January 2023

Montessori education is distinct for its implementation in 154 countries around the world. Lacking a Montessori trademark or comprehensive overseeing body, the expansion of the Montessori approach has often been diffuse and fragmented among competing organizations. The absence of centralized, accurate, and consistent accounting has made it difficult to document the scope, growth trends, and diverse populations of students served in Montessori schools. The primary objective of this study was to gather evidence to support a robust estimate of the number of Montessori schools worldwide. This estimate relies on national and regional organizations’ broadest definitions of what constitutes a Montessori program. The study included two components: a survey of regional and national Montessori organizations and supplemental sources, including other published estimates and direct inquiries within key countries. Multiple sources allowed for triangulating data to reach a more confident estimate for the number of schools in each country and for synthesizing global perspectives on significant elements of Montessori fidelity worldwide. Through these sources, we document a total of 15,763 Montessori schools around the globe, roughly 9% of which are government funded. Countries with the largest number of Montessori schools are the United States, China, Thailand, Germany, Canada, and Tanzania; the United States, Thailand, the Netherlands, and India have the largest number of government-funded or public Montessori programs. Results of the fidelity analysis identified six practices that emerge consistently as central pillars of Montessori implementation.
“Con el agua al cuello”: Una historia de batallas perdidas contra el agua y desastres por inundaciones en Colombia (1944-2011)
Authors: Mora Pacheco Katherinne
Published: January 2023

Desde mediados del siglo XIX, extensas áreas de humedales en los Andes y el Caribe colombiano se convirtieron en escenarios propicios para la implementación de proyectos de desecación, drenaje y canalización con miras a la expansión agrícola y urbana. Este artículo sintetiza la confluencia de factores que desembocaron en una lucha por la domesticación del agua, en ruptura con antiguas formas de convivencia con ríos y humedales, y fallida desde su origen por la omisión de dinámicas hídricas y ecosistémicas. Como se explica en el texto a través de coyunturas representativas registradas en la prensa, la gestión equivoca del agua ha sido una de las principales causas de los desastres repetitivos por inundaciones que han afectado, a lo largo de los siglos XX y XXI, a la Sabana de Bogotá, el valle del río Cauca y las llanuras del Caribe.
Algorithms for Path Planning in a Group of Mobile Robots in an Environment with Obstacles with a Given Template
Authors: Kostjukov V. A. , Medvedev M. Y. , Pshikhopov V. Kh.
Published: January 2023

A method is proposed for solving the problem of planning the movement of a group of ground-based robotic platforms (UGR) with the requirement to maintain a given formation of the system in the presence of stationary obstacles and sources of disturbances. The task of calculating the trajectory of the leading UGR, coupled with the use of a displacement planner and subsequent smoothing of the resulting trajectory according to the method considered in the first part of this work, is highlighted. The trajectories of the slaved elements of the group are determined by constructing offset spatial curves along which these elements should move, taking into account a given configuration or the requirements of preserving some average kinematic parameters of the elements along their trajectory. To solve the problem of evading the group from the influence of sources of disturbances, the method considered in the previous works of the authors is proposed. It is based on the calculation of the probabilities of successful passage of the elements of the group of their trajectories. These probabilities can be found after evaluating the parameters of the characteristic probability functions of the sources describing the nature of their impact on moving objects over small time intervals. In this article, this method is modified by additional optimization of the resulting spatial trajectory along the length for each UGR, taking into account a given degree of permissible deviation from the original curve. A technique has been developed that allows to find the target trajectories of the leading and driven UGR of the group, the probability of successful passage of which exceeds the specified target value. The methodology is generalized to the case when the optimization criterion is the probability of successful completion of only part of the UGR group. Simulation results confirms the effectiveness of the proposed method of planning the trajectories of robots forming a group in the field of repeller sources.

Published: January 2023

The paper presents the study of the dependence between photometric parameters of selected short-period comets of the Jupiter family and the activity of the Sun. As a quantity of solar activity, we used the sunspot area, the Wolf number, the annual mean solar radio flux, the solar flare index (full disk), and the annual mean AA-index solar activity. To study the correlation between cometary and solar activity the Dobrovolsky method was used. It has been found no direct correlation between the absolute stellar magnitude and the photometric parameter of comets with individual parameters of solar activity. Moreover, the correlation coefficients show that some comets are not associated with solar activity.

Authors: Webber Wesley B. , Soylu Firat , Burnham Joy J.
Published: January 2023

Counselors are obligated to work effectively with diverse groups, yet stereotyping and biases can impede counselors’ efforts. Understanding implicit processes in social cognition among counselors is important because implicit stereotyping and biases can negatively influence counselors’ work. Investigation of cognitive processes through electroencephalography (EEG) can illuminate implicit tendencies that potentially lead to microaggressions toward clients. In this study, we tested the hypothesis that graduate students in mental health fields would show indicators of stereotyping in a priming experiment that measured stereotyping implicitly. Both neural (N400 event-related potential component) and behavioral (reaction time) measures were used as indexes for stereotyping. The results showed neural and behavioral markers of stereotyping toward Black men and White women in a sample of graduate students in mental health fields composed of mostly White women. Implications for counseling practice and research are discussed.

Published: January 2023

The Internet of Things (IoT) refers to a global network that integrates real life physical objects with the virtual world through the Internet for making intelligent decisions. In a pervasive computing environment, thousands of smart devices, that are constrained in storage, battery backup and computational capability, are connected with each other. In such an environment, cellular networks that are evolving from 4G to 5G, are set to play a crucial role. Distinctive features like high bandwidth, wider coverage, easy connectivity, in-built billing mechanism, interface for M2M communication, etc., makes 5G cellular network a perfect candidate to be adopted as a backbone network for the future IoT. However, due to resource constrained nature of the IoT devices, researchers have anticipated several security and privacy issues in IoT deployments over 5G cellular network. Off late, several schemes and protocols have been proposed to handle these issues. This paper performs a comprehensive review of such schemes and protocols proposed in recent times. Different open security issues, challenges and future research direction are also summarized in this review paper.

Published: January 2023

In recent years, network virtualisation has been of great interest to researchers, being a relatively new and major paradigm in networking. This has been reflected in the IT industry where many virtualisation solutions are being marketed as revolutionary and purchased by enterprises to exploit these promised performances. Adversely, there are certain drawbacks like security, isolation and others that have conceded the network virtualisation. In this study, an investigation of the different state-of-the-art virtualisation technologies, their issues and challenges are addressed and besides, a guideline for a quintessential Network Virtualisation Environment (NVE) is been proposed. A systematic review was effectuated on selectively picked research papers and technical reports. Moreover a comparative study is performed on different Network Virtualisation technologies which include features like security, isolation, stability, convergence, outlay, scalability, robustness, manageability, resource management, programmability, flexibility, heterogeneity, legacy Support, and ease of deployment. The virtualisation technologies comprise Virtual Private Network (VPN), Virtual Local Area Network (VLAN), Virtual Extensible Local Area Network (VXLAN), Software Defined Networking (SDN) and Network Function Virtualisation (NFV). Conclusively the results exhibited the disparity as to the gaps of creating an ideal network virtualisation model which can be circumvented using these as a benchmark.

Messaging applications have become one of the largest and most popular smartphone applications. It includes the capacity for the users to communicate between themselves via text messages, photos and files. It is necessary to safeguard all messages. Privacy is one of the biggest issues which most individuals in the world of instant messaging ignore. Although several instant messaging applications offer varying security for users, the weaknesses and danger of data assault are increasing. Not just business discussions, our data must also be safeguarded during everyday discussions since data is very sensitive for everybody, and data protection is very crucial to prevent undesired loss of information. To address these types of weaknesses and hazards associated with data attacks, we require an encrypted messaging protocol and also hide IP address method for a safe interaction. This paper's goal is to protect conversations from targeted attacker by securing the communication between user and hide IP address from unauthorized access.
Evaluation of the effect of low-intensity rhythmic transcranial magnetic stimulation on motor and non-motor manifestations of Parkinson's disease
Authors: Borodulina Irina V. , Gerasimenko Marina Yu.
Published: January 2023

BACKGROUND: The use of repetitive transcranial magnetic stimulation as a method of non-drug therapy of Parkinson's disease has been actively studied over the past decades. The prevailing number of repetitive transcranial magnetic stimulation protocols in Parkinson's disease use a high intensity of stimulation (80120% of the value of the threshold of the evoked motor threshold from the muscles of the hand), while the choice of the stimulation intensity parameter was carried out empirically.
AIM: to study the effectiveness of low-intensity unilateral repetitive transcranial magnetic stimulation on motor and non-motor symptoms of Parkinson's disease.
MATERIAL AND METHODS:An open prospective non-randomized clinical trial included 37 patients with stage IIII Parkinson's disease according to HoehnYahr (1967), akinetic-rigid and mixed (akinetic-rigid-tremor) forms. All patients underwent repetitive transcranial magnetic stimulation according to the protocol: M1 stimulation zone, frequency 5 Hz, intensity 40% of the cortical motor threshold, on 6s, off 8s, total number of pulses per session 3000. The course of treatment is 10 procedures with 2 days (weekend) off.
RESULTS: All patients completed the study in accordance with the protocol. When analyzing the results of the UPDRS scale (Unified Parkinson's disease rating scale), positive dynamics was noted in all parts of the questionnaire: part I ― from 2 (0; 3) to 0 (0; 1) points, p 0.05; part II ― from 9 (5.5; 12.5) to 4 (2; 6.5) points, p 0.05; part III ― with 11 (7; 14.5) to 6 (2; 7.5) points, p 0.05; part IV (Schwab and England scale) ― from 80% (70; 95) to 90% (85; 100), p 0.05. There was also a selective effect on non-motor symptoms.
CONCLUSION: Low-intensity exposure (40% of the motor threshold) has a significant clinical effect on motor and non-motor symptoms of Parkinson's disease; stimulation of the primary motor cortex can have an antidepressant effect; repetitive transcranial magnetic stimulation has a selective effect on non-motor symptoms of Parkinson's disease: a predominant effect has been demonstrated with respect to olfactory, emotional, cognitive disorders, sleep disorders and hypersalivation; when assessing the dynamics of motor disorders, a more pronounced effect was noted with respect to rigidity, postural disorders, walking speed, and to a lesser extent, the effect on tremor was noted.

Aim      To determine predictors of acute kidney injury (AKI) related with surgeries for correction of acquired valvular heart disease (HD) and to evaluate the incidence of in-hospital complications in patients with postoperative AKI.

Material and methods  This study included 62 patients after surgery for correction of acquired valvular HD (mean age, 61±10.9 years) with a disease duration of 11±5.3 years. NYHA functional class (FC) 1 chronic heart failure (CHF) was observed in 1.6 % of patients, FC 2 in 64.5 %, and FC 3 in 33.9 %.17.7% of patients had chronic kidney disease (CKD). Coronary lesions of ≥50 % of vascular lumen were detected in 27.4 % of patients. Surgical correction of mitral valvular disease was performed in 32 cases, aortic valvular disease in 36 cases, tricuspid valvular disease in 8 cases, and combined operations for correction of valvular disease and coronary bypass in 8 cases. Creatinine concentrations were measured according to the Jaffe method; glomerular filtration rate (GFR) was estimated with the CKD-EPI equation. AKI was diagnosed based on KDIGO (2012) criteria.

Results The AKI incidence related with surgeries for correction of valvular HD was 16.1 % (8.1 % of patients had stage 1 AKI, 3.2 % had stage 2 AKI, and 4.8 % had stage 3 AKI), and 3.2% required kidney replacement therapy. AKI was associated with the presence of CKD at baseline (р=0.044), development of hemopericardium requiring drainage (р=0.012), more pronounced coronary lesions (in the AKI group: stenoses from 50 to 70 % in 20% of patients, from 70 to 90 % in 30 % of patients, and ≥90 % in 0 %; without AKI: from 50 to 70 % in 13.4 % of patients, from 70 to 90 % in 3.8 %, and ≥90 % in 5.8 % of patients, respectively; р=0.032). Probability of postoperative AKI significantly increased with the development of hemopericardium requiring drainage. Patients with postoperative AKI compared to persons without AKI had higher mortality (20 % and 0 %; р=0.001), greater incidence of decompensated CHF (40 and 9.6 %; р=0.012) and hemopericardium requiring drainage (30 and 1.9 %; р=0.012).

Conclusion      The development of postoperative AKI is associated with CKD at baseline, more pronounced coronary injury, and hemopericardium requiring drainage.

Aim      To determine the effect of major electrocardiographic (ECG) parameters on the prognosis of patients with COVID-19.

Material and methods  One of systemic manifestations of COVID-19 is heart injury. ECG is the most simple and available method for diagnosing the heart injury, which influences the therapeutic approach. This study included 174 hospitalized patients with COVID-19. Major ECG parameters recorded on admission and their changes before the discharge from the hospital or death of the patient, were analyzed, and the effect of each parameter on the in-hospital prognosis was determined. Results were compared with the left ventricular ejection fraction (LV EF), laboratory data, and results of multispiral computed tomography (MSCT) of the lungs.

Results ECG data differed on admission and their changes differed for deceased and discharged patients. Of special interest was the effect of the QRS complex duration at baseline and at the end of treatment on the in-hospital survival and mortality rate. The Cox regression analysis showed that the QRS complex duration (relative risk (RR) 2.07, 95% confidence interval (CI): 1.17–3.66; р=0.01), MSCT data (RR, 1.54; 95 % CI: 1.14–2.092; р=0.005), and glomerular filtration rate (GFR) (RR, 0.98; 95 % CI: 0.96–0.99; р=0.001) had the highest predictive significance. In further comparison of these three indexes, the QRS duration and GFR retained their predictive significance, and a ROC analysis showed that the cut-off QRS complex duration was 125 ms (р=0.001). Patients who developed left bundle branch block (LBBB) in the course of disease also had an unfavorable prognosis compared to other intraventricular conduction disorders (р=0.038). The presence of LBBB was associated with reduced LV EF (р=0.0078). The presence of atrial fibrillation (AF) significantly predetermines a worse outcome both at the start (р=0.011) and at the end of observation (р=0.034). A higher mortality was observed for the group of deceased patients with ST segment deviations, ST elevation (р=0.0059) and ST depression (р=0.028).

Conclusion      Thus, the QTc interval elongation, LBBB that developed during the treatment, AF, and increased QRS complex duration are the indicators that determine the in-hospital prognosis of patients with COVID-19. The strongest electrocardiographic predictor for an unfavorable prognosis was the QRS complex duration that allowed stratification of patients to groups of risk.

The femur is the longest, heaviest, and strongest bone in the human body. Morphometric study of femur can be useful for estimation of stature, prediction of femur fractures/pathologies, operative management as well as for determination of congenital anomalies.

250 dry femur bones collected from bone Store, Government Medical College, Surat, Gujarat with study done over a period of 6 months. Total length of each femur and the Foraminal Index (FI) for each nutrient foramina were obtained.

The mean total length of femur obtained was 41.22 cms. Torsion angle for both right sided as well as left sided femurs was most common in the range 11 - 14. 39.7% (48) of the total right sided femurs (121) had a torsion angle in the range 11 - 14 while 41.9% (54) of the total left sided femurs (129) also had a torsion angle in the range 11 - 14. Maximum number had a neck shaft angle in the range of 123 - 127 which constitutes 41.6% (104) of total sample size. Nutrient foramina was most commonly (48.8%) along linea aspera with most had a size corresponding to 22 gauge, which constitutes 45.7% (119) of total sample size.

Morphometric study of femur helps us to determine various factors which could be helpful for prediction, prevention and diagnosis of a certain pathology as well as for its management and treatment.
Detection of Parkinson’s Disease Using the Spiral Diagram and Convolutional Neural Network
Authors: Singh Manju , Khare Vijay
Published: January 2023

This study intends to propose a PD detection using spiral sketching and CNN. The fundamental idea is to analyze a person's spiral drawings and classify them as healthy or having Parkinson's disease. Spiral sketches drawn by healthy people look almost like standard spiral shapes. However, the spirals drawn by people with Parkinson's disease look distorted because they deviate significantly from their perfect spiral shape due to slow movement, and poor hand-brain coordination. In this paper Convolution, Neural Network is used to detect Parkinson’s, and 83.6% classification accuracy is obtained.
„Ha munkásszálló – legyen jó”

The presentation of the commuter’s ’second home’ is inevitable in connection with the research of commuting as one of the most defining social phenomena of the Kádár era. This is particularly justified in Szabolcs-Szatmár county, which area was closely connencted to the phenomenon of short-distance commuting. One of the main goals of the intertwining state and corporate social policy implemented in the era, especially from the first half of the 1960’s, was undoubtedly to ensure satisfactory living conditions and cultural services provided by workers’ hostels. While from the beginning of the 1970’s, the county’s political leadership, one of the companies employing the most commuters, the Szabolcs County State Construction Company, prioritized the matter of workers’ hostels, which had been operated since the beginning of the fifties, from the end of the sixties. The company’s efforts were mainly shown in connection with the creation of suitable hygienic conditions and the provision of cultural opportunities. However, despite the significant financial outlay, a lasting result was not achieved, as a result of which the corporate goals set in previous decades were also prioritized in the 1980’s.

Distribución de mira y fíjate en la norma culta. Un estudio en datos del español de la Ciudad de México
Authors: Guillén Escamilla Josaphat Enrique
Published: January 2023

A partir de datos de la norma culta de la Ciudad de México, este trabajo tiene dos objetivos principales, (i) describir la incidencia de los factores sociales edad y sexo en el uso de los marcadores discursivos mira/mire y fíjate/fíjese, y (ii) contrastar la frecuencia de aparición de cada uno de estos marcadores con relación al uso que de ellos se hace en otras variedades. Para tal fin, se conformó una submuestra del corpus El habla de la ciudad de México (Lope Blanch, 1971) y posteriormente se llevó a cabo un metaanálisis con los resultados provenientes de otras nueve variedades más, también de la norma culta. Los resultados señalan que, en la norma culta de la Ciudad de México, la frecuencia de uso de uno y otro marcador contrasta de manera evidente frente a la frecuencia que presentan en otras ciudades. Finalmente, también se encontró que los factores sociales sexo y edad no son determinantes en el empleo de estos marcadores.

Los árboles dispersos en pastizales son una fuente importante de nutrientes, reciclados a través de la hojarasca que los árboles liberan anualmente. El objetivo de este trabajo fue evaluar la descomposición y liberación de nutrientes de la hojarasca de Vachellia pennatula y Lysiloma acapulcense, en un clima cálidosubhúmedo. Se colocaron bolsas de descomposición y se monitoreó la humedad del suelo y temperatura ambiental bajo el dosel de los árboles y en áreas abiertas durante 32 semanas. Se utilizó un diseño de bloques al azar y se modeló la descomposición de hojarasca en cuatro tratamientos: sombra de L. acapulcense con hojarasca de L. acapulcense (1) o de V. pennatula (2); sombra de V. Pennatula con hojarasca de L. acapulcense (3) o de V. pennatula (4). Se determinó la composiciónquímica de la hojarasca. Los parámetros de calidad evaluados (relación C/N, lignina, celulosa y hemicelulosa) fueron buenos predictores del proceso de descomposición. La hojarasca remanente a las 32 semanas fue similar en todos los tratamientos (P = 0.999). En el proceso de descomposición, la constante (k) osciló entre -0.00090 y -0.00096, que denota lenta descomposición (t50 = 1.98-2.11 años, t99 = 13.2-14.0 años). El nitrógeno y el fósforo aumentaron al final del experimento debido a la probable inmovilización de estos nutrimentos por microorganismos asociados (hongos y bacterias). La descomposición y liberación de nutrientes de la hojarasca de V. pennatula y L. acapulcense en este ambiente cálido subhúmedo es relativamente lenta, independientemente del microclima generado por la sombra.
