Effects of pulsed inhaled nitric oxide delivery on the distribution of pulmonary perfusion in spontaneously breathing and mechanically ventilated anesthetized ponies
Authors: Auckburally Adam , Wiklund Maja K. , Lord Peter F. , Hedenstierna Göran , Nyman Görel
Published: December 2021

OBJECTIVE

To measure changes in pulmonary perfusion during pulsed inhaled nitric oxide (PiNO) delivery in anesthetized, spontaneously breathing and mechanically ventilated ponies positioned in dorsal recumbency.

ANIMALS

6 adult ponies.

PROCEDURES

Ponies were anesthetized, positioned in dorsal recumbency in a CT gantry, and allowed to breathe spontaneously. Pulmonary artery, right atrial, and facial artery catheters were placed. Analysis time points were baseline, after 30 minutes of PiNO, and 30 minutes after discontinuation of PiNO. At each time point, iodinated contrast medium was injected, and CT angiography was used to measure pulmonary perfusion. Thermodilution was used to measure cardiac output, and arterial and mixed venous blood samples were collected simultaneously and analyzed. Analyses were repeated while ponies were mechanically ventilated.

RESULTS

During PiNO delivery, perfusion to aerated lung regions increased, perfusion to atelectatic lung regions decreased, arterial partial pressure of oxygen increased, and venous admixture and the alveolar-arterial difference in partial pressure of oxygen decreased. Changes in regional perfusion during PiNO delivery were more pronounced when ponies were spontaneously breathing than when they were mechanically ventilated.

CLINICAL RELEVANCE

In anesthetized, dorsally recumbent ponies, PiNO delivery resulted in redistribution of pulmonary perfusion from dependent, atelectatic lung regions to nondependent aerated lung regions, leading to improvements in oxygenation. PiNO may offer a treatment option for impaired oxygenation induced by recumbency.

In this study, Taguchi-Grey relational analysis was used to investigate and optimize wear parameters such as sliding speed,
reinforcement of Gr and reinforcement of Al2O3, and their effect on dry sliding wear performance of ZA-27 nanocomposites.
Nanocomposites were synthesized via hot pressing process with pre-processing mechanical milling. Sixteen experimental tests
were performed based on design of experiments which was created with the help of Taguchi L16 orthogonal array. Grey
relational analysis (GRA) was applied for determination of optimal combination of parameters in order to improve
tribological characteristics. Optimal combination of factors, obtained with Taguchi Grey relational analysis was sliding
speed of 100 rpm, reinforcement content of 1 vol.% Gr and reinforcement content of 4 vol.% Al2O3. Validation of results was
done by using Artificial Neural Network (ANN). Developed model had overall regression coefficient 0.99836, and output
values showed good correlation with experimental results. Based on this research, it can be observed that nanocomposites
with reinforcement of Gr and Al2O3 can be potentially employed in many industries as a good substitute for the base alloy. In
addition, as a result of the analysis of the worn surfaces, it was determined that with the increase of the Al2O3 ratio, the hard
Al2O3 nanoparticles turned the dominant wear mechanism into abrasive. Also, it was determined that the Gr nanoparticles
appeared on the abrasive wear lines.

Revision and cassation in French military courts of the late XVIII – early XIX centuries: on the legal nature of permanent councils of revision
Authors: Krichevtsev Mikhail Vladimirovich
Published: December 2021

This article contains material on the history of the Permanent Councils of Revision – bodies of military justice in France of the late XVIII – early XIX centuries, which is examined in the Russian historiography for the first time, as well as poorly studied in the French historiography. Leaning on the legislative acts and works of the French lawyers of that time, analysis is conducted on the procedure for the formation of the councils of revision, and determination of their judicial competence. The article also raises the question on correlation of the concepts of “revision” and “cassation” in French military justice of the end of revolutionary and post-revolutionary eras. Consideration of the provisions of French jurisprudence of the early XIX century allows concluding that the concept of “revision” could also include cassation of court judgments. Comparison of the permanent councils of revision, which carried out the functions of cassation of court decisions, with the Cassation Tribunal (in the imperial time – the Court of Cassation) did not allow to equate these bodies, which were created separately for military and civilian justice. Having a different procedure for the formation of bench of judges, the permanent councils of revision were granted the limited authority to conduct cassation and were not of equal importance to the Court of Cassation.
Protolanguage in the context of historical consciousness
Authors: Guseva Anna Andreevna
Published: December 2021

This article examines the capabilities of protolanguage as the object of philosophy. The subject of this research is the protolanguage viewed from different perspectives: as the ideal construct, as retrotopic plot, as key to the golden age, etc. Within the framework of the philosophy of language, protolanguage largely correlates with the Adamic language, which can be considered as disappeared or subtly preserved in national languages. The search for protolanguage in the Middle Ages (and later period) requires the method of philosophical etymology that proves the closeness of the selected language to the historical primary source - the point of the origin of history. The context of protolanguage intersects not only with linguo-philosophical problematic, but also with the problem of historical consciousness. Protolanguage can be perceived as a type of internal language, or inner form of language; therefore the theme of internal form becomes the plotline for searching the language that encompasses antiquity as the criterion of truth and the ideal comprehension, when the disappearing language remains in silence, indicating the very things. The article advances an idea that the genealogical classification of languages, which includes one protolanguage underlying the linguistic family, may have such classification, which is founded not only on the comparative-historical method, but also the peculiarities of historical consciousness suggesting, for example, that for philhellene culture such protolanguage would be considered the Greek language. The question of protolanguage is attributed to not only the sphere of comparative-historical linguistics, but virtually being the question of the origin of history and human, lies in the realm of the philosophy of history, ontology, and gnoseology.
Demystifying Qualitative Research for Musculoskeletal Practitioners Part 2: Understanding the Foundations of Qualitative Research
Authors: Klem Nardia-Rose , Bunzli Samantha , Smith Anne , Shields Nora
Published: December 2021

Synopsis

In this second editorial about qualitative research for musculoskeletal practitioners, we turn our attention to the foundational assumptions that underpin all qualitative research. Specifically, we discuss research paradigms, which consist of ontological and epistemological assumptions, as well as the “lens” of the researcher. Understanding these foundational assumptions will help readers interpret the findings of qualitative studies relevant to a musculoskeletal context.

Objetivo: Identificar a prevalência de disfunção sexual em gestantes em um município do Pará. Métodos: Trata-se de uma pesquisa de caráter transversal e natureza quantitativa, realizado com vinte gestantes em um município do Pará por meio de um formulário em uma plataforma online. Resultados: Foram avaliados vinte questionários, onde entre as vinte voluntarias 25% delas tinham de 18 a 22 anos, 20% tinham de 23 a 27 anos, 25% de 28 a 32 anos e 30% acima de 32 anos. Os resultados da pesquisa demonstraram considerável prevalência de disfunção sexual nas gestantes, sendo que houve uma tendência ao aumento dos sintomas com a evolução da gestação. Os domínios mais afetados do questionário foram dor, excitação, lubrificação, satisfação, orgasmo, seguido de desejo.  Conclusão: Os domínios mais afetados do questionário foram dor, excitação, lubrificação, satisfação, orgasmo, seguido de desejo. Com isso a atuação da fisioterapia é essencial para mulheres com disfunção sexual, uma vez que há estudos que comprovam que as intervenções fisioterapêuticas aplicadas as mulheres com disfunção sexual, foram eficazes para o tratamento.

Objetivo: Identificar os fatores que interferem na não adesão de mulheres ao Teste de Papanicolaou. Métodos: Trata-se de uma revisão integrativa, realizada de forma pareada nas bases de dados CINAHL, LILACS, MEDLINE e na biblioteca virtual Scielo, entre maio e agosto de 2021 por meio dos Descritores em Saúde Women, Papanicolaou Test Uterine Cervical Neoplasms e Risk Factors, cruzados pelo operador booleano and. Selecionaram-se 19 artigos para amostra final. Resultados: Diversos fatores foram identificados como preditivos à não adesão do Teste de Papanicolaou, dentre eles: baixa renda, escolaridade, faixa etária, falta de conhecimento sobre o teste, não possuir companheiro, uso de tabaco, álcool e outras drogas, vergonha ou medo do procedimento, acreditar estar bem de saúde, dificuldade de acesso aos serviços e falta de integralidade da assistência prestada. Considerações finais: Percebe-se que os fatores associados à não adesão do Teste de Papanicolaou remetem a presença de iniquidades sociais e raciais, fatores individuais, condições e oferta dos serviços de saúde deficiente, além da cobertura insuficiente da realização do teste; sendo necessário, portanto, realizar ações educativas para sensibilizar a população sobre a importância de realizar o exame para a detecção precoce, tratamento oportuno da doença e realização de busca ativa.

En 1596 la famille de Bry, connue pour ses livres de voyages maritimes, publie les Emblemata sæcularia, une collection de gravures faisant partie du genre des emblèmes moraux. L’emblème 44 représente un laboratoire où deux patients subissent des traitements extravagants : un robinet a été introduit dans le ventre du premier, tandis que l’autre est coiffé d’un instrument alchimique qui l’aide à éliminer ses idées folles. À travers cette scène le graveur se moque de croyances ou de coutumes médicales et alchimiques propres au traitement de la folie et plus spécifiquement de la mélancolie. Cet article discute et met en lumière quelques-uns des choix iconographiques de la gravure, en plaçant ceux-ci dans le contexte plus large de la médecine, la science ou la culture populaire à la Renaissance.

Authors: Lezhenin A.A. , Raputa V.F.
Published: December 2021

A joint analysis of cases of high monthly mean concentrations of benzo(a)pyrene measured at stationary stations of Roshydromet in the atmospheric air of the cities of Novosibirsk and Iskitim of the Novosibirsk region is carried out. The influence of meteorological conditions on pollution levels is investigated. Particular attention is paid to the analysis of observational data carried out in the winter months of 2018, for which high monthly mean concentrations of benzo(a)pyrene were recorded in both cities, reaching 15–20 maximum permissible concentrations. Correlation relationships were obtained between measurements at stations in the cities of Novosibirsk and Iskitim, which indicates the determining influence of meteorological conditions on pollution levels.

With the advent of space equipment that allows obtaining panchromatic images of ultra-high spatial resolution (< 1 m) there was a tendency to develop methods of thematic processing of aerospace images in the direction of joint use of textural and spectral features of the objects under study. In this paper, we consider the problem of classification of forest canopy structures based on textural analysis of multispectral and panchromatic images of Worldview-2. Traditionally, a statistical approach is used to solve this problem, based on the construction of distributions of the common occurrence of gray gradations and the calculation of statistical moments that have significant regression relationships with the structural parameters of stands. An alternative approach to solving the problem of extracting texture features is based on frequency analysis of images. To date, one of the most promising methods of this kind is based on wavelet scattering. In comparison with the traditionally applied approaches based on the Fourier transform, in addition to the characteristic signal frequencies, the wavelet analysis allows us to identify characteristic spatial scales, which is fundamentally important for the textural analysis of spatially inhomogeneous images. This paper uses a more general approach to solving the problem of texture segmentation using the convolutional neural network U-net. This architecture is a sequence of convolution-pooling layers. At the first stage, the sampling of the original image is lowered and the content is captured. At the second stage, the exact localization of the recognized classes is carried out, while the discretization is increased to the original one. The RMSProp optimizer was used to train the network. At the preprocessing stage, the contrast of fragments is increased using the global contrast normalization algorithm. Numerical experiments using expert information have shown that the proposed method allows segmenting the structural classes of the forest canopy with high accuracy.

Published: December 2021

The process describes an intelligent system creation designed for risk evaluation and management. The risk can be anthropogenic, natural, or social nature, and belong to territories of different scales. Complexity in structuring and collecting information about the state territorial security as well as different risks assessment methods necessitate the development of a modular multitask system. The information management system support model formalizes the problem area to justify the joint intelligent technologies use. Based on the model, system architecture has been developed. This architecture defines the composition, functionality, interaction interfaces, as well as the information resources organization, that were used to support management. Here is presented an intelligent system prototype operation result.
