Introduction: The article is the product of the investigation of the determination of the concentration of particulate matter PM2.5, estimating the influence of temperature and precipitation, developed at the Universidad Libre, Bogotá Headquarters between the years 2018-2019.
Problem: Concentrations of particulate matter have increased in recent years in Bogotá, generating a serious environmental problem, concentrations that have been caused by the automotive fleet and industries.
Objective: To determine the relationship of the particulate material with the meteorological variables Precipitation and Temperature, and the influence of the contributing sources of PM2.5 in the studied area.
Methodology: For the determination of [PM2.5] a WilBur model low volume sampler was used, the meteorological data were obtained from the Bogotá Air Quality Monitoring Network of the Secretary of the Environment. Softwares such as ArcGis, WRPLOT and MiniTab were used for the graphical representation of the results.
Results: The average [PM2.5] for dry and wet season was 9.03 and 19.22μg / m3. . For the meteorological variables, a precipitation of 40.4 and 373.6 mm, a temperature of 14.3 and 15.32 ° C, respectively, was obtained.
Conclusion: There is a low relationship between meteorological variables and [PM2.5] in both monitoring seasons, however, a behavior of concentrations similar to that found in the literature is evidenced.
Originality: PM2.5 sampling in both seasons within the Free University, cataloged as a background area.
Limitations: The monitoring time for the year 2018 was in the months of July and August and the year 2019 from March to May.
Tornar-se pai: as implicações da reprodução humana assistida para a paternidade
Authors: Haslinger Camile , Bottoli Cristiane 
Published: October 2021

A família vem sofrendo inúmeras transformações na contemporaneidade, bem como o papel do homem/pai nesse contexto. A reprodução humana assistida pode acompanhar o desejo de tornar-se pai, sendo uma possibilidade de, efetivamente, realizá-lo, trata-se da intervenção do homem no processo de procriação natural, com o objetivo de permitir que pessoas com problemas de infertilidade e esterilidade alcancem o desejo pela parentalidade. A presente pesquisa objetivou compreender, através do tornar-se pai, qual a experiência do homem diante do processo de reprodução humana assistida, buscando também entender o processo de decisão e planejamento do pai diante da RHA, investigar se houve mudanças na relação do casal durante todo o processo e identificar os desafios da função paterna no contexto de reprodução humana assistida. A pesquisa foi desenvolvida sob a abordagem qualitativa e exploratória. Participaram do estudo três homens/pais que tiveram filhos fruto do processo de RHA (fertilização in vitro). Os dados, por sua vez, foram colhidos por meio de entrevistas semiestruturadas. Os depoimentos dos participantes do estudo foram analisados pela técnica de Análise de Conteúdo. Entende-se que o homem/pai conquistou um lugar muito importante na parentalidade, constatando-se que ser pai por meio da RHA ou de forma tradicional revelam, em si, momentos de extrema ansiedade e angústia, mas a função paterna e cuidados dedicados ao filho é a mesma em ambas, conforme a literatura descreve, bem como a transmissão de valores, convocando esse pai a readaptar-se, de forma efetiva, ao seu novo lugar tanto na conjugalidade como na parentalidade.

A második magyar filológus, Joannes Baptista Novosoliensis
Authors: Kiss Farkas Gábor 
Published: October 2021

This study presents the editorial work of a hitherto little known 16th century philologist from the Kingdom of Hungary, Joannes Baptista Novosoliensis of (Neuzohl) Banská Bystrica, Slovakia. After having earned the bachelor’s degree in Cracow (1499) and further studies in Bologna (1523) under Giovan Battista Pio and Lazzaro Bonamico, he moved back to Cracow in 1527, where he published four editions for the sake of his students. Although there is sufficient information about all four, only two of them survive, an edition of Cicero’s Pro Marco Marcello (1528), and the Ad Quintum fratrem 1, 1. He added marginal notes and a detailed commentary to his edition of the Ad Quintum fratrem 1, 1, which include references to textual criticism and to a now lost manuscript of Cicero’s letter in the San Domenico convent of Bologna. An analysis of the variant readings in the edition has shown, that Novosoliensis was using Andreas Cratander’s 1528 Basel edition of Cicero as a starting point in establishing the text.
Pacorus és az elképzelt régi magyar irodalom néhány 16. századi francia forrása

Published: October 2021

Dans mon étude, je traiterai des traductions françaises de la nouvelle Historia de duobus amantibus d’Aeneas Silvius Piccolomini. La première partie de mon étude est de nature bibliographique : il s’agit simplement de corriger quelques erreurs figurant dans le catalogue French Vernacular Books et de fournir des renseignements sur les traductions françaises et leurs auteurs. La seconde partie est consacrée au rôle que remplit dans l’intrigue de la nouvelle le personnage prétendument ’hongrois’: j’examine les interprétations que les traducteurs donnent de l’appartenance de Pacorus à la nation pannonius et les transformations qu’ils font subir à sa personne. Il s’avérera que deux des traducteurs français n’ont pas hésité à sacrer poète notre héros: ils lui ont fait ’composer’ les deux lettresà Lucretia que Piccolomini a seulement mentionnées. Belle contribution au corpus ’imaginaire’ de la littérature hongroise...

Authors: Montiel Larissa Wayhs Trein , Campos Míria Izabel 
Published: October 2021

O atendimento coletivo das crianças nas creches no Brasil se pautou pela ideia preconcebida de que a mulher, por sua natureza feminina, seria mais bem preparada para assumir as funções naqueles espaços. Nesse contexto, o objetivo geral neste texto foi dar visibilidade às trajetórias de profissionalização docente de mulheres educadoras de Naviraí, Mato Grosso do Sul. Para tanto, elencaram-se como objetivos específicos saber quando se tornaram monitoras de creche; quais motivos e/ou interesses as levaram à escolha profissional; como questões de gênero permearam e refletiram nas trajetórias de vida e profissão; e de que forma compreenderam a necessidade de uma profissionalização docente para se estabelecerem na carreira. Utilizou-se como recurso metodológico a História Oral temática, tendo sido realizadas entrevistas, as quais foram analisadas à luz do referencial teórico eliasiano. Percebeu-se que as políticas educacionais pensadas para o atendimento à criança pequena geraram uma alteração na carreira destas profissionais, e isso se refletiu em suas trajetórias de formação docente. Compreendeu-se que rememorar os aspectos envolvidos no percurso de suas vidas e trajetórias profissionais possibilitou o entendimento de como as figurações, isto é, as redes de interdependência, foram constituídas pelas mulheres educadoras e ao mesmo tempo as constituíram, trazendo à tona questões de gênero e poder inerentes aos diferentes tempos e espaços de trabalho e formação.

Computer components for solving the problems of optimal control of the rolling stock of the railways of Ukraine
Authors: Dmitrienko Valerii , Mezentsev Mykola 
Published: October 2021

The solution of the problems of optimal control of traction rolling stock, as a rule, is performed under the assumption that the external environment in relation to the composition remains unchanged and does not affect or weakly affects the laws of control. However, the actual movement of trains on the railway makes significant changes to the pre-calculated laws of control and schedules. In this regard, the article considers approaches to the control of the composition taking into account changes in the state of the environment. Such approaches require the identification of the external environment in the process of movement of a particular composition and the correction of control laws when changing the parameters of the external environment. In this case, there is a transition to proactive control. Figs.: 1. Refs.: 16 titles.
Buoyancy Force on a Plain or Perforated Portion of a Pipe
Authors: Cayeux E. , Stokka S. , Dvergsnes E. W. , Thorogood J. L. 
Published: October 2021

Summary
Torque and drag models have been used for several decades to calculate tension and torque profiles along drillstrings, casing strings, and liner strings. Buoyancy forces contribute to the loads acting on the pipe and affect its interaction with the borehole wall. Torque and drag calculations account for these localized effects, as well as the material internal forces, torques, and moments on each side of the contact. When the analysis is applied to a discrete length of pipe, the cross sections at each end do not contribute to the buoyancy forces because they are not in contact with the fluid, except where there is a change in diameter or at the end of the string of pipe.
We argue that it is important to check that the models used for solid pipe torque and drag calculations remain valid for sand screens, in particular, the extent to which the buoyancy forces acting on a perforated tube might differ from those on a solid pipe. Because the buoyancy force is the result of the pressure gradient acting on the surface of the pipe, the presence of holes may also influence the buoyancy force. We propose that there are theoretical differences between local buoyancy forces acting on plain or perforated tubes.
This paper describes how to calculate the local buoyancy force on a portion of a drillstem by the application of Gauss’ theorem and accounting for the necessary corrections arising from the cross sections not being exposed to the fluid. We built an experimental setup to verify that the tension inside a pipe subject to buoyancy behaves in accordance with the derived mathematical analysis. With complex well construction operations, for instance during extended-reach drilling or when drilling very shallow wells with high buildup rates, the slightest error in torques and drag calculations may end up jeopardizing the chances of success of the drilling operation. It is therefore important to check that the basis of design calculations remain valid in those contexts and that, for instance, sand screens or slotted liners may be run in hole safely after a successful drilling operation.

Abstract
Aging causes significant structural and functional changes in the vasculature, disrupting homeostasis and affecting the cardiovascular system's performance. This study looked into the effects of aging on the aorta and how that affects antioxidant capability. As a result, healthy aging female SD rats (n=10) were compared to their younger counterparts. Blood pressure, serum lipid profile, aortic histology examination, and the expression of antioxidant enzymes were all assessed. When aged rats were compared to young rats, their blood pressure and serum lipid levels were dramatically different. Furthermore, histological examination of the aorta of aging rats revealed structural changes, characteristic apoptotic nuclear morphology, and the formation of fatty deposits. Different antioxidant enzyme’s protein expression was also studied. In aged rats, the expressions of SOD-1(superoxide dismutase), GSS(glutathione synthetase), NRF2(NF-E2-related factor 2), KEAP-1(Kelch-like ECH-associated protein 1), and HO-1(Heme oxygenase 1) were drastically changed. This study revealed that age-induced aortic changes are associated with an altered antioxidant system, according to this study.

Published: October 2021

Abstract

Background
the presence of lymph node metastases is one of the most important prognostic factors for long-term survival of patients with colorectal cancer. So, thorough pathologic examination of at least 12 lymph nodes is essential for accurate staging this disease, as well as choosing the best adjuvant treatment. The aim of this study is to assess the adequacy of lymph node harvest in patients with colorectal cancer.
Methods
This observational cross-sectional study was performed on 584 patients with colorectal adenocarcinoma who had undergone surgery from 2012 to 2017. Thereafter, the relevant demographic, pathological, and surgical data were extracted from the patients’ medical records and a relationship between the number of evaluated lymph nodes and other variables was also assessed.
Results
Among 584 studies cases in this study, 336 (57.5%) subjects had less than 12 evaluated lymph nodes. Mean and median number of the evaluated lymph nodes were calculated as 10.7 (± 5.6) and 10, respectively. The patients aged 60 years old and older and the cases with tumors located in descending colon and rectum were observed to have higher chances of inadequate lymph node retrieval. After an average follow-up for a 60-month period, 63% of the patients were alive. In the patients for whom less than 12 lymph nodes had been assessed, the median survival was estimated as 48 months. As well, in the patients for whom the number of the evaluated lymph nodes was ≥ 12, median survival was calculated as 54 months.
Conclusion
The number of the evaluated lymph nodes in our study was less than the standard number in more than half of the patients. Among various factors, older age, and tumor location in descending colon and rectum are found to be associated with sub-optimal assessment of lymph nodes. The number of lymph nodes dissected is also associated with survival.

Abstract
Purpose: To report normative data on paediatric refractive and ocular indices in kindergarten Israeli children. Methods: Retrospective cross-sectional study of 101,417 Israeli children from 4-5 years old, obtained from 2013-2018. Data was collected using the PlusoptiX S12. We studied the number of referrals made for hyperopia, myopia, astigmatism and anisometropia. Results: Mean sphere value was 0.83D±0.73 for the right eye and 0.85D±0.73 for the left eye. Mean SE was 0.56D±0.66 for the right eye and 0.59D±0.67 for the left eye. Mean cylinder value was -0.53D±0.48 for the right eye and was the same, -0.53D±0.47, for the left eye. Mean axis values for the right and left eyes were 80.85°±55.57 and 80.42°±56.60 respectively. Mean pupil size was 5.83mm±0.87 for the right eye, and 5.82mm±0.88 for the left eye. 13.26% had anisocoria ≥0.4mm; of these, 0.66% had anisocoria >1.0mm. There was no difference in pupil size between sexes or different cities. Mean IPD was 49.58mm±3.50, and mean gaze vector value was 2.64±1.66. According to the Vision Screening Guidelines, 0.8% of children had hyperopia and 0.17% had myopia. 6.22% of children had astigmatism and 10.85% had anisometropia. ﻿Conclusion: Amblyopia is the most common cause of unilateral vision loss in childhood. The earlier the diagnosis, the better the outcome, hence the importance of investigating the causative indices leading to amblyopia in kindergarten. After searching the literature, this is the largest study population for this topic to our knowledge.

Published: October 2021

Abstract
The study of biomarkers in free-living birds can help indicate the degree of contamination in distinct environments. In addition, these environments can be characterized through the information provided by satellite images. The objectives of the present study were to analyze the types and quantity of cytogenetic biomarkers in Passer domesticus (sparrow) from three different environments; wild, rural and urban; and to analyze them in the context of land use and anthropogenic actions. Five thousand erythrocytes per bird were analyzed for the following nuclear alterations (NA): micronuclei (MN), nuclear buds, notched nuclei, binucleated cells, nucleoplasmic bridges, nuclear tails, peripheral nuclei and enucleated cells. In the study, wild birds exhibited five types of NA, seven types were found in rural birds; and all types were encountered in urban birds. The only NA that exceeded a frequency of 2 NA/ 1000 erythrocytes were peripheral nuclei in birds from the rural and urban sites, the latter environment characterized by 87% urban soil and air pollution. The highest frequencies of MN, peripheral nuclei and enucleated erythrocytes were recorded in sparrows from the rural site (p≤0.05). This area had been sprayed with chlorpyrifos 48%, the most widely used organophosphate in the region. Sparrows from the wild site, made up of 100% native forest, had higher frequencies of notched nuclei (p≤0.05). A precedent is set for the use of environmental remote sensing in a complementary manner with cytogenetic biomarker studies in birds for a joint analysis in environmental assessment.

Abstract
This study aims to investigate the effect of low temperature on the gene expression in Ophiocordyceps Sinensis. To set up the experiments, two groups of Ophiocordyceps Sinensis were grown at 4°C and 18°C, respectively, for 60 days. Differential gene expression was analyzed by transcriptome sequencing and the morphology of mycelium was studied under scanning electron microscope for the two groups. The results showed that there were significant differences in hypha morphology between the two groups. Transcriptome analysis indicated that 2799 genes were differentially expressed in the low-temperature treatment group compared to the normal temperature group. Among these genes, 1489 were up-regulated, whereas 1310 were down-regulated. Further analysis revealed that 33 genes were only expressed at low temperature compared to 26 genes which were only expressed at normal temperature. GO enrichment analysis showed that the 33 genes were related to redox enzymes, which have functions in clearing reactive oxygen species and free radicals caused by low-temperature environment. KEGG enrichment analysis showed that the 33 genes were mainly involved in the cyanoamino acid metabolism, biosynthesis of amino acids, carbon metabolism, pantothenate and CoA biosynthesis, biotin metabolism, phenylpropanoid biosynthesis, apoptosis and other metabolic pathways. Our observations provide fundamental clues on the relationship between the low-temperature stimulation and the fruiting body development and further promote the research progress on Ophiocordyceps Sinensis.
Comparison of multi-axis printing strategies effects on large-scale 3D printed surface quality
Authors: Krčma Martin , Paloušek David 
Published: October 2021

Abstract
The purpose of this study is to determine impact of several multi-axis 3D printing strategies on buildability, surface quality, accuracy and strength of large scale single-walled object (printed in a so called vase mode). To achieve this goal, test objects were printed using four distinct printing strategies by an industrial robotic arm and a pellet-fed screw extruder. The strategies tested in this study are: regular 3-axis deposition with planar layers, 5-axis deposition with planar layers, 3-axis deposition with non-planar layers, and 5-axis deposition with non-planar layers. Custom scripts for nonplanar slicing and for tilt control during multi-axis printing were developed to achieve these prints and are explained in this study. The results were evaluated using 3D scanning and mechanical testing, and surface accuracy, surface roughness and layer adhesion strength were compared. The most important findings are: 1. 5-axis motion alone does not improve the results of the printing, 2. While nonplanar printing can improve surface quality its usability is geometry dependent, 3. Multi-axis nonplanar printing, even with partial tilt (30°) can expand printability with enhanced quality to at least 75° overhang angle. Future potential of these methods and requirements to achieve them is discussed.
