AIM: To evaluate the possibilities of flow detection using high resolution flow (HR Flow) and Glazing Flow technique in patients with liver parenchymal changes and flow changes in comparison to color-coded Doppler sonography (CCDS). MATERIAL AND METHODS: All examinations were performed using a multi frequency matrix convex probe with high resolution technique (SC6-1U/Resona7, Mindray, Shenzhen, China) by one experienced examiner to evaluate the venous, portal venous and arterial liver flow with digital documentation of the dynamic flow parameters like peak systolic flow, end-diastolic flow and resistance index. For liver parenchymal stiffness changes shear wave elastography was performed with at least 10 measurements. By two independent readers an elevation was performed to evaluate the image quality and the degree of flow artefacts, from 0 = not available to 5 points with excellent image quality without flow artefacts. RESULTS: All 40 patients (24 men, 16 women, age 27–83 years, mean 56±5 years) showed morphology changes from B-Mode of the liver parenchyma to inhomogeneous tissue with higher stiffness evaluated by the shear wave elastography (1.45 m/s up to 2.79 m/s±1.79 m/s, considering F1 up to F4 fibrosis) and in 15 cases histopathologically proven liver cirrhosis. In 9 cases after non-acute thrombosis flow reduction of the portal vein was the reason for the diameter less than 5 mm. Flow parameters for the venous flow were between 8 cm/s up to 29 cm/s, mean 14±4 cm/s, for the hepatic portal vein 5 cm/s up to 57 cm/s, mean 17±5 cm/s, for the hepatic artery systolic flow between 50 cm/s up to 127±33 cm/s, end-diastolic flow from 22 cm/s up to 47±8 cm/s. Resistance index for the hepatic artery was between 0.41 up to 0.73, mean 0.67±0.25. The image quality for CCDS over all cases was evaluated for CCDS between 1 up to 4. The mean quality was 2.5±0.5, for HR Flow in combination with Glazing Flow 3±0.5, with significant differences for the 2 readers (P < 0.01). CONCLUSION: Combination of HR Flow with Glazing Flow could be helpful to evaluate morphological und hemodynamic changes of liver arterial flow, portal venous and venous flow. Reduction of flow artefacts in combination with a higher image quality could be helpful for optimizing the digital measurements also for follow up examinations.
Effects of gastrocnemius stretching with talus-stabilizing taping on ankle dorsiflexion and balance in individuals with limited ankle dorsiflexion: A randomized controlled trial
Authors: Jung Jong-Chul , Shin Yong-Il , An Da-In , Park Won-Young , Kim Soo-Yong
Published: August 2021

BACKGROUND:

Various interventions have been recommended to increase ankle dorsiflexion range of motion (DFROM); however, few studies have investigated the long-term effects of applying gastrocnemius stretching with talus-stabilizing taping (GSTST).

OBJECTIVE:

To compare the effects of gastrocnemius stretching (GS) and GSTST on DFROM and balance in subjects with limited DFROM.

METHODS:

Twenty-six subjects with limited DFROM were randomly allocated to either the GS group ([Formula: see text] 13) or GSTST group ([Formula: see text] 13) for 6 weeks. Maximum DFROM before heel-off during gait, passive DFROM, posterior talar glide, flexibility of the gastrocnemius, and the lower-quarter Y-balance test (YBT-LQ) were assessed pre-intervention and post-intervention. Two-way repeated-measures analysis of variance was used to compare the changes in variables.

RESULTS:

The GSTST group had greater maximum DFROM before heel-off, passive DFROM, and posterior talar glide than the GS group. Gastrocnemius flexibility and YBT-LQ scores increased significantly post-intervention in both groups; however, there was no significant difference between the groups.

CONCLUSIONS:

GSTST is recommend for improving ankle DFROM and balance in subjects with limited DFROM.

The consistency of cerebrospinal fluid amyloid-β (Aβ)42/40 ratio and Aβ42 has not been assessed in the AT(N) classification system. We analyzed the classification changes of the dichotomized amyloid status (A+/A–) in 363 patients tested for Alzheimer’s disease biomarkers after Aβ42 was superseded by the Aβ42/40 ratio. The consistency of Aβ42 and the Aβ42/40 ratio was very low. Notably, the proportions of “false” A+T–patients were considerable (74–91%) and corresponded mostly to patients not clinically diagnosed with Alzheimer’s disease. Our results suggest that the interchangeability of Aβ42/40 ratio and Aβ42 is limited for classifying patients in clinical setting using the AT(N) scheme.

Recently, there were much interest in technology which has emerged greatly to the development of smart unmanned systems. Internet of UAV (IoUAV) enables an unmanned aerial vehicle (UAV) to connect with public network, and cooperate with the neighboring environment. It also enables UAV to argument information and gather data about others UAV and infrastructures. Applications related to smart UAV and IoUAV systems are facing many impairments issues. The challenges are related to UAV cloud network, big data processing, energy efficiency in IoUAV, and efficient communication between a large amount of different UAV types, in addition to optimum decisions for intelligence. Artificial Intelligence (AI) technologies such as Machine Learning (ML) mechanisms enable to archives intelligent behavior for unmanned systems. Moreover, it provides a smart solution to enhance IoUAV network efficiency. Decisions in data processing are considered one of the most problematic issues related to UAV especially for the operations related to cloud and fog based network levels. ML enables to resolve some of these issues and optimize the Quality of UAV network experience (QoE). The paper provides theoretical fundamentals for ML models and algorithms for IoUAV applications and recently related works, in addition to future trends.

Published: August 2021

Whilst some studies investigated the impact of viral infection or reduced access to medication during the COVID-19 pandemic in patients with Parkinson’s disease (PD), data on the effects of pandemic restrictions are still scarce. We retrospectively analyzed motor symptoms of longitudinally followed PD patients (n = 264) and compared motor disease progression before and during the COVID-19 pandemic. Additionally, we performed a trend analysis of the yearly evolution of motor symptoms in 755 patients from 2016 until 2021. We observed a worsening of motor symptoms and a significantly increased motor disease progression during pandemic-related restrictions as compared to before the COVID-19 outbreak.

Published: August 2021

Bowling effectiveness is a key factor in winning cricket matches. The team captain should decide when to use the right bowler at the right moment so that the team can optimize the outcome of the game. In this study, we investigate the effectiveness of different types of bowlers at different stages of the game, based on the conceded percentage of runs from the innings total, for each over. Bowlers are generally categorized into three types: fast bowlers, medium-fast bowlers, and spinners. In this article, the authors divided the twenty over spell of a T20I match into four stages; namely, Stage 1: overs 1-6 (PowerPlay), Stage 2: overs 7-10, Stage 3: overs 11-15, and Stage 4: overs 16-20. To understand the broad spectrum of the behavior of game variables, a Quantile Regression methodology is used for statistical analysis. Following that, a Bayesian approach to Quantile Regression is undertaken, and it confirms the initial results.

Authors: Cordero L. , Stenger M.R. , Landon M.B. , Nankervis C.A.
Published: August 2021

OBJECTIVE:

To compare breastfeeding (BF) initiation among 317 women with chronic hypertension (CHTN) and 106 women with CHTN superimposed on pregestational diabetes (CHTN-DM) who intended exclusive or partial BF.

METHODS:

Retrospective cohort study of women who delivered at≥34 weeks of gestation. At discharge, exclusive BF was defined by direct BF or BF complemented with expressed breast milk (EBM) while partial BF was defined by formula supplementation.

RESULTS:

CHTN and CHTN-DM groups were similar in prior BF experience (42 vs 52%), intention to BF exclusively (89 vs 79%) and intention to partially BF (11 vs 21%). Women in the CHTN group were younger (31 vs 33y), more likely primiparous (44 vs 27%), and delivered vaginally (59 vs 36%) at term (85 vs 75%). Women in the CHTN-DM group had higher repeat cesarean rates (32 vs 18%), preterm birth (25 vs 15%), neonatal hypoglycemia (42 vs 14%) and NICU admission (38 vs 16%). At discharge, exclusive BF rates among CHTN was higher (48 vs 19%), while rates of partial BF (34 vs 44%) and FF (18 vs 37%) were lower than in the CHTN-DM group. BF initiation (exclusive plus partial BF) occurred in 82%of CHTN and in 63% of CHTN-DM.

CONCLUSION:

Although intention to BF was similar, BF initiation rates were higher for the CHTN compared to the CHTN-DM group. Exclusive BF was low in the CHTN and even lower in the CHTN-DM group signaling the need for targeted interventions if BF initiation rates are to be improved.

Published: August 2021

Repetitive transcranial magnetic stimulation (rTMS) of the brain is an effective clinical treatment for psychiatric disorders. Noninvasive neuroimaging during rTMS allows visualization of cortical brain activations and responses, and it is a potential tool for investigating the neurophysiological response occurring actively during stimulation. In this paper, we present a fast diffuse optical tomography (DOT) approach for three-dimensional brain mapping of hemodynamics during rTMS. Eight healthy subjects were enrolled in the study. These subjects received 10 Hz stimulation with 80%and 100%of resting motor threshold (rMT), respectively, for 4 seconds for each stimulation. Significant hemodynamic activation was observed in all cases with the strongest response when 100%rMT stimulation was applied. This work demonstrates that fast DOT has the potential to become a powerful tool for noninvasive three-dimensional imaging of the brain during rTMS.

BACKGROUND AND OBJECTIVE: Monitoring recovery process of coronavirus disease 2019 (COVID-19) patients released from hospital is crucial for exploring residual effects of COVID-19 and beneficial for clinical care. In this study, a comprehensive analysis was carried out to clarify residual effects of COVID-19 on hospital discharged patients. METHODS: Two hundred sixty-eight cases with laboratory measured data at hospital discharge record and five follow-up visits were retrospectively collected to carry out statistical data analysis comprehensively, which includes multiple statistical methods (e.g., chi-square, T-test and regression) used in this study. RESULTS: Study found that 13 of 21 hematologic parameters in laboratory measured dataset and volume ratio of right lung lesions on CT images highly associated with COVID-19. Moderate patients had statistically significant lower neutrophils than mild and severe patients after hospital discharge, which is probably caused by more efforts on severe patients and slightly neglection of moderate patients. COVID-19 has residual effects on neutrophil-to-lymphocyte ratio (NLR) of patients who have hypertension or chronic obstructive pulmonary disease (COPD). After released from hospital, female showed better performance in T lymphocytes subset cells, especially T helper lymphocyte% (16% higher than male). According to this sex-based differentiation of COVID-19, male should be recommended to take clinical test more frequently to monitor recovery of immune system. Patients over 60 years old showed unstable recovery process of immune cells (e.g., CD45 + lymphocyte) within 75 days after discharge requiring longer clinical care. Additionally, right lung was vulnerable to COVID-19 and required more time to recover than left lung. CONCLUSIONS: Criterion of hospital discharge and strategy of clinical care should be flexible in different cases due to residual effects of COVID-19, which depend on several impact factors. Revealing remaining effects of COVID-19 is an effective way to eliminate disorder of mental health caused by COVID-19 infection.
Consciousness as a new form of the matter’s state
Authors:   “World Public Lab” Private Research Laboratory (Lithuania), Maydykovskiy Igor
Published: August 2021

The article discusses the physical model of the implicative form of Consciousness in the form of a holographic wave matrix, for which the material basis is directly the phase environment that fills the entire Space. It is shown that a similar form of Consciousness that exists outside the human brain can be represented as a kind of software shell that controls all forms of matter by implementing a fractal cyclic iterative algorithm. The condition for the completion of each iterative cycle at each scale level is the observance of the laws of symmetry that ensure the survival of the object in the process of copying-incarnation.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] "Given the advantages of ML, this research thesis focuses on developing appropriate methodologies to solve the problems that inherit in the three phases of the traditional research paradigm: chemical space designing, characterization data analysis, manual experimental conduction. The goal is to accelerate the materials development with the aid of ML towards autonomous manufacturing. Correspondingly, the research work consists of three parts: (i) guiding materials synthesis by ML; (ii) automating XRD spectra analysis by convolutional neural networks (CNNs); (iii) accelerating materials processing via combination of ML and a robotic platform. The part I corresponds Chapter 2, the part II corresponds to Chapter 3, and part III includes Chapter 4 and Chapter 5. In summary, Chapter 2 describes a well-trained ML model to predict the crystallinity propensity of metal-organic nanocapsules (MONCs). Chapter 3 reports a convolutional neural networks (CNNs) for rapid identification of X-ray diffraction (XRD) patterns of metal-organic frameworks (MOFs). Chapter 4 shows development of efficient materials synthesis methodologies, i.e., microwave-/Joule-heating for accelerating the synthesis of MOFs using laser-induced graphene (LIG) microreactors. Chapter 5 illustrates a robotic synthesis platform that is powered by ML algorithms for optimizing the crystallinity of MOFs. Chapter 6 concludes the research work and presents the possible research direction in future."--From Introduction.
The role of TRAF3IP2 in obesity-associated vascular insulin resistance and dysfunction
Authors:   , Grunewald Zachary I.
Published: August 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Insulin resistance in the vasculature is a characteristic feature of obesity and contributes to the pathogenesis of vascular dysfunction and disease. However, the molecular mechanisms underlying obesity-associated vascular insulin resistance and dysfunction remain poorly understood. We hypothesized that TRAF3 Interacting Protein 2 (TRAF3IP2), a pro-inflammatory adaptor molecule known to activate pathological stress pathways and implicated in cardiovascular disease, plays a causal role in obesity-associated vascular insulin resistance and dysfunction. We tested this hypothesis by employing genetic-manipulation in endothelial cells in vitro and in isolated arteries ex vivo, and by using a mouse model of TRAF3IP2 ablation and diet-induced obesity in vivo. We show that forced expression of TRAF3IP2 blunts insulin signaling in endothelial cells and diminishes endothelium-dependent vasorelaxation in isolated aortic rings. Further, 16 weeks of high fructose/high sucrose (HFHS) feeding impaired glucose tolerance, aortic insulin-induced vasorelaxation, and hindlimb postocclusive reactive hyperemia, while increasing blood pressure and arterial stiffness in wild-type male mice. Notably, TRAF3IP2 gene ablation protected mice against such metabolic and vascular defects caused by HFHS feeding. Interestingly, wild-type female mice expressed markedly reduced levels of TRAF3IP2 mRNA independent of diet and were protected against HFHS diet-induced vascular dysfunction. These data indicate that TRAF3IP2 plays a causal role in vascular insulin resistance and dysfunction. Specifically, the present findings highlight a sexual dimorphic role of TRAF3IP2 in vascular control and identify it as a promising therapeutic target in vasculometabolic derangements associated with obesity, particularly in males.
Genome-wide investigation of alcohol response : a meta-analytic review and polygenic associations with alcohol use disorder
Authors:   , Deak Joseph D.
Published: August 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] The current study aimed to extend previous genetic studies of level of response (LR) to alcohol by conducting the largest genome-wide association study (GWAS) of LR to date through the meta-analysis of multiple samples with extant SRE (Self-rating of the Effects of Alcohol) and GWAS data. A second aim was to use summary data from the described GWAS of LR to create polygenic risk scores (PRS) in an independent sample in order to determine whether, and to what extent, the genetic influences underlying LR to alcohol serve as a risk factor for alcohol use disorder (AUD). Towards these aims, datasets were processed according to standard quality control (QC) procedures allowing for genotype imputation and GWA analysis using methods appropriate for the individual study designs. Following individual study-level GWAS analysis, results were meta-analyzed utilizing an inverse-variance weighted fixed-effects model in METAL resulting in a final sample size of N=10,635. GWAS summary statistics from the SRE meta-analysis were then used to conduct gene-based and gene-set analyses, as well as compute polygenic risk scores (PRS) in an independent target sample to examine the predictive ability of the LR to alcohol PRS for DSM-IV AD symptom counts. No individual variants, genes, or gene-sets achieved study-level significance, although multiple genetic loci of interest achieved suggestive significance. The top single variant association was in an intergenic region on chromosome 2 located near the FUNDC2P2 gene (rs12463481; p=6.35x10[superscript -8]), the top gene-based association was with the PRR16 gene on chromosome 5 (p=6.72x10 [superscript -6]), and the top gene-set was with a set of genes associated with NFE2L2 targets (p=1.21 x10 [superscript -5]). No results from the PRS analysis approached significance. These findings suggest that, similar to other alcohol use outcomes, larger sample sizes will be required for the robust detection of genetic influences contributing to level of response to alcohol.
Beyond the border war : student civil rights activism at the University of Kansas and the University of Missouri, 1946-1954
Authors:   , Brown Mary Beth
Published: August 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] This dissertation examines post-World War II student civil rights activism at two Midwestern college campuses, the University of Missouri (MU) and the University of Kansas (KU). Missouri and Kansas have conflicting histories concerning race dating back to Bleeding Kansas and the history of race relations on the campuses of KU and MU. This history is especially complicated during the period between 1946 and 1954 because of heightened student activism that challenged racial injustices. Race relations on campus largely mirrored that of the state's political environment, with KU having integrated in the 19th century, whereas MU did not desegregate until 1950. However, the same did not apply to the success of student activists at each school where MU students found success fighting against discriminatory practices in Columbia, whereas local business leaders and the university administration stymied KU students. The dissertation examines the exchange of ideas and strategy among students, which occurred through athletics, debates, guest speakers, and various regional and national groups. In particular, the study argues that campus spaces, such as residential co-ops and student organizations, were deeply significant because they served as incubators of activism by offering students a place to talk about racial and social injustice and plan ways to challenge these inequalities and effect change on campus and in the broader community.
Racial discrimination and mental health : temporal dynamics and neurocognitive moderators
Authors:   , Volpert-Esmond Hannah I.
Published: August 2021

Experiencing racial discrimination is related to both mental and physical health (Mays et al., 2007; Pascoe and Richman, 2009; Schmitt et al., 2014). However, much of this research focuses on population-level relationships using cross-sectional samples and questionnaires, which is unable to examine temporal relationships between the experience of racial discrimination and mental health outcomes. The current study examined the effect of racial discrimination experience by Black college students at the University of Missouri using Ecological Momentary Assessment. A complex temporal relationship between reported discrimination and affect, depression, and anxiety emerged, such that reports of discrimination had an immediate negative effect, resulting in higher levels of negative affect, depression, and anxiety. However, this negative effect did not persist and instead resulted in an increase in positive affect several hours after the report. Additionally, neurocognitive indices of attention to threat neither corresponded as expected to frequency of reports of discrimination, nor moderated the effect of discrimination as expected.

Authors: Nasution Atika Fadhilah Danaz , Nuraidah Nuraidah , Imelda Imelda
Published: August 2021

Introduction: Sleep needs in infants 3-12 months are not only in terms of quantity but also quality. Good quality sleep provides benefits to the fulfilment of physical and psychological needs. One method of meeting these needs is baby massage. A common reason for mothers to give baby massages is the child’s habit of fussing at night and often waking up, and they say that after the massage, their child becomes calm at night. This study aims to analyze the effect of baby massage on the sleep quality of infants aged 3-12 months at private midwife Muji Kenali Asam in Jambi City. Material and Methods: This pre-experimental study consisted of a one-group pretest-posttest design for a group of 68 infants aged 3-12 months. The questionnaire was compiled into a google form, and the link was distributed to each mother. Data processing consists of editing, coding, tabulating and statistical tests (Wilcoxon test) at the limit of significance value of 0.05. Results: The study results that can be described are that most of the sleep quality of infants aged 3-12 months before the intervention was sufficient at 45.6%, and for poor quality, it was 27.9%. After the intervention, most infants aged 3-12 months were good in sleep quality by 45.5% and sufficient sleep quality by 52.9%. The results of the Wilcoxon test revealed the effect of infant massage on infant sleep quality with a significance value of p-value = 0.001. Conclusion: Baby massage tends to improve the baby’s sleep quality. Therefore Midwifery students need to acquire baby massage skills and promote the method to mothers, particularly those with babies 3-12 months.

Relationship Between the Quality of Realization of Extracurricular Activities and the Number of Students Attending Extracurricular Activities/Sections
Authors: Čolović Danijela D.
Published: August 2021

The aim of the research is to determine the quality of the realization of sections in relation to the number of students who choose to participate in these activities. Through the analysis of the research results, conclusions will be drawn on the basis of which measures will be created to improve the work in this area. The measures will ensure the dynamic development of the sections and their more successful implementation, which will be reflected in terms of the number of interested students, but also the complete psychophysical and social development of students, in accordance with their individual and priority needs. Survey and document analysis techniques were used in the research. Questionnaires (for students, parents and teachers) were used as research instruments. The questionnaires were conducted using digital means (Google questionnaires), which facilitated their distribution, data collection and analysis of results. All steps in the research are described by the descriptive method. The primary school had 30 classes of the first and 17 classes of the second cycle in the previous school year (at the time of conducting the research). The sample was formed by surveying students from each class under numbers 2, 5, 8, 11, 14, 17, 20 and 23, as well as their parents and teachers. The analysis confirmed that significantly more students of the first cycle than students of the second cycle are involved in extracurricular activities/sections, as well as that students are satisfied in certain aspects of the implementation of sections, but that there is an opportunity to improve work. At the school, teachers encourage students to apply for participation in sections (mostly talented who would certainly achieve their ambitions by attending additional classes). It is important to hire students who want to participate, even though they do not have a preference for a particular subject or area to which the section is dedicated.

This track design is not rational under current operating conditions. The use of a more advanced jointless track design in curves with a radius of less than 350 m is limited primarily by the condition of ensuring the transverse stability of the rail-sleeper lattice. To be able to expand the use of jointless track construction in curved sections with a radius of less than 350 m, it is necessary to know the values of the transverse forces of interaction of the structures of the upper track structure with the moving carriage. Knowing the forces of interaction, it is possible to estimate by what value the transverse stability of the rail-sleeper lattice will be provided and to make constructive decisions on its increase. The method of determination of transverse horizontal forces of interaction of track and moving carriage in curves of radius less than 350 m taking into account quasi-static compressive forces in a train is given. The reasons for these forces are related to the presence of eccentricity of the autoclutch shank in the horizontal and vertical planes. Theoretical calculations of horizontal transverse forces of interaction are carried out according to the given technique and coefficients of stability of a rail-sleeper lattice in curved sites are defined. The main conclusions concerning the possibility of operation of the jointless track structure in curved sections with a radius of 350 m and less are made.

The problem of breaks automatic coupling is becoming urgent for outbound transport. in the robot, a number of defects are shown, which were found in the damaged car parts. Carrying out an analysis of the equipment of the vehicle will indicate the presence of a stock of performance, and if there is a defect in the deteriorated parts of the vehicle, it will be overwhelmed by the stock. An analysis of the normative documentation and methods in the control of car breakdowns is necessary to provide information on the methods of ruinous and non-rudimentary control, so that it can be done when preparing and repairing car breakdowns. Tom found the crocodile in the first place in the world of problems and is to blame for the increase in the quality of control to the body of the vehicle. Proponent is the acoustical control, and the very thin or mirror-thin method for the control of the shank of the autozchep in the screw hole before the wedge of the traction clamp. The robots of the methods runtuyu on the change in the amplitude of the signal when passing through the discontinuity of the metal, which allows the appearance of internal defects. These methods allow the appearance of significant internal defects such as metal discontinuities, but also to reduce the speed of car breakdowns through the appearance of this type of defect. On the basis of the obvious methods for the control of internal defects, the methods are projected that are irregular and can be stagnated to all auto-breakdowns due to minor preparation of the surface for control.

The current state of the freight wagon fleet is characterized by increased physical wear over time. Disproportionate renewal of rolling stock, low quality of repair due to the lack of appropriate modernization of production systems, the peculiarities of loading and unloading operations in operation make increased demands on the preservation of the wagon fleet. The issues of general management of the transport safety system deserve special attention. Control of safety of freight wagons should be carried out at all stages of operation: at freight works, at transfer in the international and domestic communication, at maintenance and repair. In this case, each stage requires the use of appropriate regulations, which ensures compliance with the conditions of storage of freight wagons in operation. The presented article analyzes the current state of the freight wagon fleet with a view to ensuring their safety during operation. The factors that are the most influential in terms of effective management of the wagon fleet are identified. Possible conservation strategies are considered. The statistical material on failures and damages of wagons is resulted. Based on this, an assessment of the most significant events in terms of the impact on ensuring the safety of wagons was made. Practical solutions for creating an effective system for preserving rolling stock in transport are proposed.
ESTIMATION OF VEHICLE OPERATING TIME TAKING INTO ACCOUNT THE INFLUENCE OF A NUMBER OF FACTORS

Published: August 2021

Modern vehicles operated on the railways of Ukraine have almost exhausted or exceeded their resource. The overuse of financial and material resources for their maintenance continues. The standard service life of vehicles was calculated on stable economic conditions of use of vehicles and their timely updating in process of aging. The service life of modern vehicles is determined by the influence of many factors, the disregard of which can lead to significant costs, even in compliance with the standard service life. For railway transport, these factors need modern clarification, as in operation their service life often exceeds the standard or, as for intermodal transport, the service life does not have a strict justification. Accordingly, the article analyzes the issues of assessing the impact on the service life of vehicles of the components of the cost of its maintenance and average daily mileage. It is shown that, firstly, the definition of the service life of vehicles must be linked to the cost of vehicle development, its creation, testing and production, the cost of operation and storage, as well as additional costs, and secondly , with the optimal average daily mileage, at which all the costs are minimal.

La pandemia del Covid-19 ha desolado naciones y pueblos, configurando un escenario de devastación que sobrepasa la emergencia sanitaria y que nos coloca frente al abismo de nuestra propia existencia en el planeta. En este artículo sostenemos que este punto de inflexión marca un cambio de época donde la trasgresión de las fronteras entre los seres humanos y otros-que-humanos ha desencadenado constantes crisis ambientales y sociales. A partir de la relectura del concepto de Antropoceno en tiempos de pandemia, postulamos el término Coronaceno para denominar una época caracterizada por profundas transformaciones en las relaciones sociales y ambientales, que complejiza la crisis civilizatoria develada e intensificada por el Covid-19, al tiempo que abre una posibilidad de reorganización para la regeneración de la vida.

A lo largo de décadas han surgido diversas teorías que han influido en las decisiones de las empresas a través del tiempo respecto a la decisión del pago de dividendos, como la Teoría de la preferencia fiscal derivada del efecto clientela, que indica que los pagos de dividendos elevados reducen el valor de la empresa porque generan una clientela (los accionistas) que prefieren disminuir su carga impositiva cuando existen tasas diferenciadas que gravan más severamente el pago a través de dividendos que el generado por la distribución de ganancias de capital (Elton & Gruber, 1970).Con la entrada en vigor de la Reforma Fiscal del año 2014, en México se introdujeron cambios sustanciales respecto a la tributación por la distribución de dividendos o utilidades. México pasó de un sistema de imputación total a adoptar un sistema dual que grava de manera adicional con un 10% en forma de retención directa y con carácter de pago definitivo a los accionistas personas físicas que lo reciben, aunado al incremento a la tarifa máxima que les aplica del 5% y la limitante en el monto máximo de sus deducciones personales, lo que incrementa su carga impositiva y reduce su riqueza personal.
