Arctic Phobias, Social Fears of Russians, Russophobia
Authors: Lukin Yu. F.
Published: January 2021

The purpose of this paper is to study the concepts and content of phobias in societies, to understand the differences between them, and to classify people’s fears. In their study, the authors use methods of the Humanities: philosophy, conflictology, historicism; data from sociological surveys of the population. The formation of fears in the life of any society occurs both under the influence of traditional views of people inherent in antiquity, and under the influence of the societal pattern as a whole — culture, civilization, as well as modern transformations related to ecology, climate, development of natural resources, security, Russophobia, fears of coronavirus, racism. The paper considers historical phobias in the Arctic as well. The problems of social phobias in the scientific literature have not yet received such a wide and deep study as in social phobia, Agora phobia, and specific phobias.
Countering International Extremism
Authors: Karimova M. S.
Published: January 2021

The article is devoted to the study of countering international extremist activity features, including the intensifying corresponding Internet threats. The author notes that in modern conditions, threats of extremism require an integrated approach at the national and international levels, more effective mobilization of state and interstate forces and resources (financial, information, etc.), including acts of blocking relevant contacts and illegal virtual resources. The article contains statistical data showing an increase in extremist threats, including the youth environment, and, accordingly, the need to intensify and expand measures to counter such negative phenomena.
Legal Regulation of Crimes Threatening Global Security
Authors: Klyukanova T. M. , Mikhailova O. O.
Published: January 2021

The authors consider methods of legal regulation of crimes and types of international cooperation in the fight against them. The paper also highlights international measures aimed at implementing antiterrorist cooperation and combating illegal drug trafficking. The main goal is to determine the legal mechanisms for the prevention of these socially dangerous phenomena both at the local and interstate levels. The object of the research is the social relations that develop in connection with and about the peculiarities of crimes that infringe on international security. The subject of the research is the norms of modern Russian criminal law and the norms of international law. The scientific works of the authors listed in the references represent a solid theoretical and methodological basis for this research. However, research into the features of crimes should continue, since not all problematic issues in this area have been resolved. The author examines the concept, content and general features of international crimes that infringe on international security; defines the role of the UN (United Nations) and other organizations engaged in international legal regulation in the fight against international crimes; defines the features of the interstate organizations activities to prevent terrorism and illicit trafficking in narcotic and psychotropic substances. It is concluded that terrorism and illicit drug trafficking are most widespread among international crimes. The authors draw conclusions on the need to perform preventive activities aimed at preventing the Commission of international crimes, as well as on the implementation of a direct fight against such crimes through «detection, prevention, suppression, disclosure and investigation». Summarizing the authors’ points of view on the subject of criminal liability for acts of terrorism and drug trafficking, it should be noted that restraint measures, as well as strengthening responsibility measures, should be preceded by a set of preventive measures. It should also be understood that the effectiveness of anti-terrorist and anti-drug policies in the world, including in terms of the regulation of criminal liability measures, should be supported and approved by the population. To improve the legal structures of crimes that infringe on international security in the countries of the world community, it is necessary to positively perceive the international experience of various states in regulating measures of criminal responsibility and countering the spread of these acts.
$\omega\sigma$-веерные классы Фиттинга
Authors: Камозина Олеся Владимировна
Published: January 2021

Рассматриваются только конечные группы. Класс групп $\mathfrak F$ называется классом Фиттинга, если он замкнут относительно нормальных подгрупп и произведений нормальных $\mathfrak F$-подгрупп; формацией, если он замкнут относительно фактор-групп и подпрямых произведений; формацией Фиттинга, если $\mathfrak F$ является формацией и классом Фиттинга одновременно.

Для непустого подмножества $\omega$ множества простых чисел $\mathbb P$ и разбиения$\sigma =\{\sigma_i\mid i\in I\}$, где $\mathbb P=\cup_{i\in I}\sigma_i$ и $\sigma_i\cap\sigma_j=\varnothing$ для всех$i\not =j$, в работе вводятся $\omega\sigma R$-функция $f$ и $\omega\sigma FR$-функция $\varphi$. Областью определения данных функций является множество $\omega\sigma\cup\{\omega'\}$, где$\omega\sigma=\{ \omega\cap\sigma_i\mid\omega\cap\sigma_i\not =\varnothing\}$,$\omega'=\mathbb P\setminus\omega$. Областью значений функций является множество классов Фиттинга и множество непустых формаций Фиттинга соответственно. С помощью функций $f$ и $\varphi$ определяется$\omega\sigma$-веерный класс Фиттинга $\mathfrak F=\omega\sigma R(f,\varphi )=(G: O^\omega (G)\in f(\omega' )$ и $G^{\varphi (\omega\cap\sigma_i )}\in f(\omega\cap\sigma_i )$ для всех $\omega\cap\sigma_i \in\omega\sigma (G))$ с$\omega\sigma$-спутником $f$ и $\omega\sigma$-направлением $\varphi$.

В работе приведены примеры $\omega\sigma$-веерных классов Фиттинга. Выделены два вида $\omega\sigma$-веерных классов Фиттинга: $\omega\sigma$-полные и $\omega\sigma$-локальные классы Фиттинга. Их направления обозначены $\varphi_0$ и $\varphi_1$ соответственно. Показано, что каждый непустой неединичный класс Фиттинга является $\omega\sigma$-полным классом Фиттинга для некоторого непустого множества$\omega\subseteq\mathbb P$ и любого разбиения $\sigma$. Получен ряд свойств $\omega\sigma$-веерных классов Фиттинга. В частности, дано определение внутреннего$\omega\sigma$-спутника и показано, что каждый $\omega\sigma$-веерный класс Фиттинга всегда обладает внутренним $\omega\sigma$-спутником. При $\omega=\mathbb P$ введено понятие $\sigma$-веерного класса Фиттинга. Показана связь между $\omega\sigma$-веерными и $\sigma$-веерными классами Фиттинга.

Authors: Мейрманов Анварбек Мукатович , Гальцев Олег Владимирович
Published: January 2021

В работе доказывается сильная компактность последовательности $\{\tilde{c}^{\,\varepsilon}(\boldsymbol{x},t)\}$ в $\mathbb{L}_{2}(\Omega_{T})$,$\Omega_{T}=\Omega\times(0,T)$, $\Omega\subset \mathbb{R}^{3}$, ограниченную в пространстве $\mathbb{W}^{1,0}_{2}(\Omega_{T})$ с последовательностью производных по времени$\left\{ \displaystyle \frac{\partial}{\partial t}\big(\chi(\boldsymbol{x},t,\frac{\boldsymbol{x}}{\varepsilon})\tilde{c}^{\,\varepsilon}(\boldsymbol{x},t)\big) \right\}$ ограниченной в пространстве $\mathbb{L}_{2}\big((0,T);\mathbb{W}^{-1}_{2}(\Omega)\big)$,где характеристическая функция $\chi(\boldsymbol{x},t,\boldsymbol{y})$ есть 1-периодическая в $\displaystyle \boldsymbol{y}\in Y=\left(-\frac{1}{2},\frac{1}{2}\right)^{3}\subset \mathbb{R}^{3}$.

В качестве приложения рассмотрим усреднение уравнения диффузии-конвекции в непериодической структуре, заданной 1-периодической в $\boldsymbol{y}$ характеристической функцией $\chi(\boldsymbol{x},t,\boldsymbol{y})$ с последовательностью бездивергентных скоростей $\{\boldsymbol{v}^{\varepsilon}(\boldsymbol{x},t)\}$, слабо сходящейся в $\mathbb{L}_{2}(\Omega_{T})$.

Ограниченный оператор сдвига для (k, 1)-обобщенного преобразования Фурье
Authors: Иванов Валерий Иванович
Published: January 2021

В пространствах с весом Данкля $v_k(x)$ степенного типа на $\mathbb{R}^d$, определяемым системой корней и неотрицательной функцией кратности $k$, инвариантной относительно конечной группы отражений, построен содержательный гармонический анализ. Классический анализ Фурье на евклидовом пространстве соответствует случаю $k\equiv 0$. В 2012 году Салем Бен Саид, Кобаяши и Орстед определили двупараметрическое $(k,a)$-обобщенное преобразование Фурье, действующее в пространствах с весом $|x|^{a-2}v_k(x)$, $a>0$. Наиболее интересны случаи $a=2$ и $a=1$. При $a=2$ обобщенное преобразование Фурье совпадает с преобразованием Данкля и оно хорошо изучено. В случае $a=1$гармонический анализ, важный, в частности, в задачах квантовой механики, изучен пока еще не достаточно. Одним из существенных элементов гармонического анализа является ограниченный оператор сдвига, позволяющий определить свертку и структурные характеристики функций. При $a=1$ имеется оператор сдвига $\tau^yf(x)$. Его $L^p$-ограниченность недавно установлена Салемом Бен Саидом и Делеавалом, но только на радиальных функциях и при $1\le p\le 2$. В настоящей работе предложен новый оператор обобщенного сдвига $T^tf(x)$. Он получается интегрированием оператора $\tau^yf(x)$ по единичной евклидовой сфере по переменной $y'$, $|y'|=1$, $y=ty'$. Мы доказываем, что он положителен на функциях из пространства Шварца $\mathcal{S}(\mathbb{R}^d)$, для него $T^t1=1$ и он допускает представление с вероятностной мерой. Отсюда мы выводим его $L^p$-ограниченность для всех $1\le p<\infty$ и ограниченность на пространстве $C_b(\mathbb{R}^d)$ непрерывных ограниченных функций.

ANÁLISE MODAL NUMÉRICA DE UMA PASSARELA DE PEDESTRES
Authors: Lago Guilherme Leite , Birck Gabriel , Toso Marcelo André
Published: January 2021

Passarelas são utilizadas para realizar a travessia de um local a outro devido a terrenos acidentados, rodovias ou lagoas e rios. Geralmente, são estruturas esbeltas, mas que devem ser bem dimensionadas, para manter a segurança e tranquilidade dos usuários. Entretanto, existem efeitos que podem surgir devido a interação entre o usuário e a estrutura que geram vibrações que podem ocasionar desconfortos aos pedestres e avarias, ou até mesmo o colapso da estrutura. Nesse contexto, o objetivo do trabalho foi realizar uma análise pelo método de elementos finitos da passarela que faz a ligação do prédio nove e onze da Universidade do Vale do Taquari (Univates), para obtenção das frequências naturais e dos modos de vibração da estrutura. Este estudo é motivado através de percepções de pedestres que verificaram que a estrutura possui movimentos vibratórios elevados. Preocupado com o conforto e principalmente com a segurança dos pedestres em geral, o trabalho apresenta comparações entre as frequências resultantes da estrutura e as frequências do caminhar de pessoas. Verifica-se que o telhado e arcos laterais apresentam vibrações susceptíveis aos pedestres, enquanto o piso da estrutura comporta-se de modo mais estável.

Published: January 2021

Atualmente, as instituições de ensino oferecem aos estudantes uma infinidade de eventos. Entretanto, devido a essa grande variedade, os alunos acabam tendo dificuldades para decidir no que se inscrever. Uma alternativa a este problema é a utilização de um Sistema de recomendação (SR), possibilitando a instituição de ensino ofertar aos alunos os melhores eventos de acordo com seu perfil e interesses. Posto isto, o objetivo principal deste trabalho foi desenvolver um sistema de recomendações de eventos, para a Univates. No processo de desenvolvimento do SR, foi utilizada a técnica de aprendizagem por máquina, sendo que os dados filtrados foram processados com o auxílio da framework Apache Mahout, através de filtragem colaborativa, que é a filtragem que busca perfis similares ao do usuário para criar recomendações. A fim de verificar a qualidade das recomendações geradas, foi realizada uma avaliação com usuários reais, sendo eles alunos e funcionários da instituição, a fim de gerar 3 recomendações. Com relação às avaliações feitas para as 3 recomendações geradas, o resultado de pontuação média de 7,78 demonstra a grande aceitação dos usuários ao sistema proposto. Os resultados demonstram que o objetivo geral de criar um sistema de recomendações de eventos utilizando a framework Apache Mahout foi atingido.

Authors: Thiesen Icléia , Frota Maria Guiomar da Cunha
Published: January 2021

O Sistema Nacional de Informação e Contra-Informação (SISNI) foi criado para dar sustentação ao regime de exceção que vigorou no Brasil no período de 1964 a 1985, incorporando alguns arquivos existentes anteriormente e criando uma complexa estrutura institucional apoiada nas ações de espionagem, polícia política, repressão e propaganda. O volume extraordinário de documentos produzidos pelos órgãos integrantes desse Sistema no período reflete práticas intensivas de ações de vigilância. Este artigo tem por objetivo analisar estratégias de produção e organização dos documentos visando a efetiva recuperação de informações secretas nos arquivos do Serviço Nacional de Informação (SNI) e da Assessoria Especial de Segurança e Informações (AESI), posteriormente denominada Assessoria de Segurança e Informações (ASI) da Universidade Federal de Minas Gerais (UFMG), vinculada ao MEC. Visava sobretudo a tomada de decisões com vistas à repressão imediata contra aqueles considerados inimigos do regime. Além da análise de conteúdo dos respectivos manuais produzidos com vistas à facilitação da identificação de nomes, organizações, partidos políticos, entre outros, será necessário recontextualizar as condições de produção das engrenagens dessa fábrica de arquivos sensíveis. As relações entre arquivo, memória e história serão abordadas no sentido de evidenciar a materialidade do campo documentário na mediação das ações de informação.

Authors: Zhao Dan , Liu Yuxin , Gao Jingzi , Liu Shaogang , Dong Liqiang , Cheng Mingshen
Published: January 2021

As the fatigue life prediction of wire rope has the defects of large
samples and many interference factors, this paper takes the 6×31WS+FC
type wire rope as research carrier. Based on small samples, the grey
particle filter method has been creatively proposed to realize the wire
rope fatigue life prediction under various load conditions. First,
combining the reliability life data prediction with the equivalent
alternating stress of the dangerous part during the fatigue test, the
reliability stress-life curve was determined. Subsequently, the particle
filter method has been used to modify the curve to obtain the modified
P-S-N curve. Finally, with theory of fatigue damage accumulation, the
fatigue life prediction model was established, and compared with the
test results. The results show that based on small sample conditions,
the proposed method can predict the fatigue life of wire ropes under
various loading conditions with high precision, which proves the general
applicability.

Published: January 2021

Objectives Takayasu Arteritis (TA) is a rare non-specific vascular
inflammation and has deleterious effects on patients’ health. Recent
studies have advanced in TA diagnosis and treatment, but the research on
the immune cell atlas of peripheral blood is still less. For this
purpose, we performed single-cell RNA sequencing (scRNA-seq) to analyze
the inflammatory cell types and cell markers in TA patients’ Peripheral
blood mononuclear cells (PBMCs). Methods 4 TA patients and 4 health
controls were enrolled in our study from 2019.10 to 2020.5. Their PBMCs
samples were collected and performed scRNA-seq. We used Seurat package
(v.3.2.2) in R studio (v.3.5.3) for data analysis, and 2 tests were
applied for comparing the composition ratio of each cell type by SPSS
20.0. Results CD14+ monocytes, GZMB+ NKT cells, CD56dim CD16+ NK cells,
and naive B cells were significantly increased in TA patients as
compared to healthy controls and the expression of THBS1, CD163, AREG,
IFITM1, TXNIP, and IGHGs was elevated in the peripheral blood of TA
patients. Conclusion Except CD4+ T cells, monocytes, NK cells, NKT
cells, B cells also play an important role in TA pathogenesis. The
elevated markers have different functions in different types of PBMCs,
and they can be used as potential diagnostic markers for TA diagnosis.
GLUCOCORTICOSTEROID DURING PATCH APPLICATION TO IMPROVE SCAR OUTCOME AFTER CENTRAL VENOUS CATHETER. A RANDOMIZED TRIAL
Authors: Nissen Ida Bo , Handrup Mette Møller , Bang Karen , Hasle Henrik
Published: January 2021

Introduction: Children treated for cancer with a central venous catheter
are often bothered by scarring. We studied whether glucocorticosteroid
during patch occlusion has a beneficial effect on scar outcome in
children and adolescents treated for neoplastic disease. Methods: A
double-blinded placebo-controlled randomized clinical trial was
performed. The main outcome was the Vancouver Scar Scale (VSS).
Secondary outcomes were scar width and scar quality measured using the
Patient and observer scar assessment (POSAS). The patients were divided
into an intervention groups and a control group. The intervention group
was randomized into two groups; Active and placebo group. The active
treatment consisted of cream with glucocorticosteroid and fusidic acid.
The placebo treatment consisted of cream with fusidic acid. Both groups
were also treated with a silicone gel patch for three months after
central venous catheter removal. The control group did not receive any
specific skin care. Results: Assessment at 6 months were completed for
44 in the intervention group (21 in the active and 23 in the placebo
group) and 47 in the comtrol group. The intervention group had a
significantly lower VSS and a smaller scar compared to the control group
(p = 0.00, p = 0.02). The POSAS by the patients and the study nurse
showed no significant difference between the intervention and control
groups (p = 0.84, p= 0.36). Conclusions: Silicone gel sheet alone or in
combination with application of glucocorticosteroid during sheet
occlusion improved scar outcome after removal of central venous catheter
in children treated for neoplastic diseases.
Odd chain fatty acids and odd chain phenolic lipids (alkylresorcinols): Essential for diet?
Authors: Dornan Kelly , Gunenc Aynur , Oomah B. Dave , Hosseinian Farah
Published: January 2021

Odd chain fatty acids (C15:0 and C17:0) from dairy fat as well as odd
chain phenolic lipids (alkylresorcinols) from whole grain are commonly
reviewed as candidate biomarkers for dietary analysis and their
ingestion are inversely related to chronic disease risks. Therefore, low
levels of dietary intake of these odd chain molecules may be related to
higher risk of physiological states that cause chronic diseases or
mortality. It is a prerequisite to examine and understand their main
role in beneficial health effects in disease prevention. We propose odd
chain fatty acids (OC-FA) and most importantly odd chain phenolic lipids
(OC-PL) as potential essential dietary compounds since they play key
roles in physiological mechanisms. This review evaluates potential roles
of OC-FA and OC-PL in mitigating chronic diseases in vitro and in vivo
studies to support our hypothesis for odd chain molecules as essential
dietary lipids. Further studies are needed to investigate the
relationship between reduced intake of OC-FA and OC-PL containing foods
and susceptibilities to chronic diseases.
Towards the Trustworthy AI
Authors: Katulić Tihomir
Published: January 2021

After decades of theoretical deliberations, the rapid development of advanced
information technology has allowed machine learning as a first practical step
towards artificial intelligence to enter widespread commercial and government
use. The transition into a post-industrial, information society has revealed the
value of data as an important resource whose processing is the basis of the new
innovative information society services. The European Union has enacted several important regulations and directives in the recent past to protect the recognized fundamental rights of individuals and to regulate the obligations of service providers to ensure safe and secure processing. The Charter of Fundamental Rights as the legal basis of the European system of human rights contains significant checks and limitations to the effect and purpose of future EU AI regulation. Whenever and however this regulation is adopted, it will need to comply with and contain existing European legal standards regarding the fundamental rights of individuals in the EU. The European Commission’s ethical guidelines establish ethical principles based on the recognized fundamental rights that future AI systems need to adhere to in order to be recognized as trustworthy. The purpose of this paper is to present and analyse the mechanisms present in existing European regulations in the fields of data protection and information security and in the European Union documents regarding the future
artificial intelligence regulation and to offer suggestions for future regulations.
The research methodology includes a comparative analysis of available regulations and policy documents of the European Union, national laws, legal literature, and other sources.
FM radio u vrijeme pandemije bolesti COVID-19
Authors: Mučalo Marina , Šulentić Anita , Jugo Damir
Published: January 2021

Hrvatska radiodifuzija ima gotovo stogodišnju tradiciju koja, osim programa
javnoga radijskog servisa (Hrvatskog radija), počiva na nakladnicima odnosno
koncesionarima za radijsko emitiranje raznih područja čujnosti, većinom komercijalnoga programskog usmjerenja. Radijski medij dosad je bio poznat po
svojoj programskoj fleksibilnosti i brzoj prilagodbi iznenadnim i kriznim situacijama te vodećoj ulozi u informiranju svojih sredina tijekom njihova trajanja.
Hrvatsku je tijekom ožujka i travnja 2020. godine zahvatila epimedija COVID-19
koja je rezultirala nizom strogih izolacijskih mjera i priprijećenim kaznama za
njihovo kršenje. Gotovo u isto vrijeme, Zagreb je 22. ožujka 2020. pogodio i
snažan potres magnitude 5,5 po Richteru, a tijekom idućih tjedana i deseci slabijih. Jedinstvenost ove dvostruke krize predstavljala je ključni razlog za provođenje istraživanja o snalaženju radija u tim kriznim okolnostima. Odabir vremenskog okvira (od 26. ožujka do 27. travnja 2020.) učinjen je namjerno, s
ciljem „snimanja“ situacije u vremenu u kojem se kriza zaista i odvijala. Poseban motiv jest i činjenica da je uloga radija u kriznim situacijama izrazito malo
zastupljena u recentnoj domaćoj znanstvenoj produkciji.
Metodološki, riječ je o kvalitativnom i deskriptivnom istraživanju koje se temelji
na analizi odgovora iz upitnika. Pitanja otvorenog tipa (30 pitanja) grupirana su u tri glavne teme i to organizaciju rada na radiju, uređivačku politiku i komunikaciju sa slušateljima. Upitnik je poslan svim radijskim nakladnicima na području Grada Zagreba i Zagrebačke županije (N=22), od čega ih se 13 (56,5 %)
odazvalo i sudjelovalo. Rezultati su pokazali da su programski sadržaji, usprkos
dvjema kriznim situacijama, uglavnom ostali isti, uključujući i one informativne. Imajući na umu dinamičan rast i afirmaciju online medija, koji zahvaljujući
digitalnoj tehnologiji ostvaruju podjednaku brzinu protoka svih vrsta informacija kao i FM radio, otvara se pitanje može li radio ikako zadržati svoj nekadašnji status.
A fractal model for the crystallization kinetics
Authors: Wang Yan
Published: January 2021

The Kolmogorov-Johnson-Mehl-Avrami equation is wildly applied in the crystallization kinetics, and Avrami exponent involved in the equation plays an important role in crystallization process. Here we show that the Kolmogorov-Johnson-Mehl-Avrami equation can be obtained by a fractal crystallization model, and the exponent is explained as the fractal dimension in time, which depends upon the chain length and molecule weight.
Variational theory for (2+1)-dimensional fractional dispersive long wave equations

Published: January 2021

This paper extends the (2+1)-dimensional Eckhaus-type dispersive long wave equations in continuous medium to their fractional partner, which is a model of non-linear waves in fractal porous media. The derivation is shown briefly using He?s fractional derivative. Using the semi-inverse method, the variational principles are established for the fractional system, which up to now are not discovered. The obtained fractal variational principles are proved correct by minimizing the functional with the calculus of variations, and might find potential applications in numerical modeling.

OBJECTIVE

A post hoc analysis to investigate the association between 1-year changes in albuminuria and subsequent risk of cardiovascular and renal events.

RESEARCH DESIGN AND METHODS

LEADER was a randomized trial of liraglutide up to 1.8 mg/day versus placebo added to standard care for 3.5–5 years in 9,340 participants with type 2 diabetes and high cardiovascular risk. We calculated change in urinary albumin-to-creatinine ratio (UACR) from baseline to 1 year in participants with >30% reduction (n = 2,928), 30–0% reduction (n = 1,218), or any increase in UACR (n = 4,124), irrespective of treatment. Using Cox regression, risks of major adverse cardiovascular events (MACE) and a composite nephropathy outcome (from 1 year to end of trial in subgroups by baseline UACR [<30 mg/g, 30–300 mg/g, or ≥300 mg/g]) were assessed. The analysis was adjusted for treatment allocation alone as a fixed factor and for baseline variables associated with cardiovascular and renal outcomes.

RESULTS

For MACE, hazard ratios (HRs) for those with >30% and 30–0% UACR reduction were 0.82 (95% CI 0.71, 0.94; P = 0.006) and 0.99 (0.82, 1.19; P = 0.912), respectively, compared with any increase in UACR (reference). For the composite nephropathy outcome, respective HRs were 0.67 (0.49, 0.93; P = 0.02) and 0.97 (0.66, 1.43; P = 0.881). Results were independent of baseline UACR and consistent in both treatment groups. After adjustment, HRs were significant and consistent in >30% reduction subgroups with baseline micro- or macroalbuminuria.

CONCLUSIONS

A reduction in albuminuria during the 1st year was associated with fewer cardiovascular and renal outcomes, independent of treatment. Albuminuria monitoring remains an important part of diabetes care, with great unused potential.
Comparison of the Tibial Anatomical-Mechanical Axis Angle and Patellar Positions between Labrador Retrievers and Golden Retrievers with and without Cranial Cruciate Ligament Rupture
Authors: L Guenego
Published: January 2021

This study investigated proximodistal and craniocaudal patellar positions and assessed these positions with the tibial anatomical-mechanical axis angle (AMA-angle), tibial plateau angle (TPA), relative tibial tuberosity width (rTTW), and Z-angle in Labrador Retrievers (LR) and Golden Retrievers (GR) with and without cranial cruciate ligament rupture (CCLR). Mediolateral radiographs were obtained from 2 groups. The affected group had a normal contralateral stifle measured at the time of unilateral surgically confirmed CCLR, which developed a subsequent contralateral CCLR (SC-CCLR; 40 dogs), and the control group (60 dogs aged >11 years) had normal stifles. In the SC-CCLR group, 95% of the tibial anatomical axes (AAs) were cranial (CR) to the patella, with a median (range) AMA-angle of 2.92° (1.65°-4.92°), while in the control group, 93% of the stifles had AAs caudal (CA) to or in the middle (M) of the patella, with a median (range) AMA-angle of 1.03° (0°-3.52°). The craniocaudal position of the patella was correlated statistically with the AMA-angles (median (range), 0.86° (0-1.61°), 1.87° (1.22-2.7°), and 2.97° (1.72-4.92°) in the CA, M, and CR positions, respectively, but not with other tibial measurements (p<0.0001). The patellar height did not differ between the groups (p<0.0001). The highly significant difference found in the AMA-angle and the craniocaudal patellar position between LR and GR with or without CCL injury suggest that craniocaudal angulation of the proximal tibia could influence the development of canine CCLR.

Objetivos: Os objetivos deste estudo foram avaliar a prevalência de perda auditiva em pacientes diagnosticados com doença falciforme (DF) acompanhados no Ambulatório de Hematologia do Conjunto Hospitalar de Sorocaba e correlacionar os achados com o tipo de hemoglobinopatia. Métodos: Neste estudo, foram incluídos 19 pacientes com diagnóstico de DF, sendo 68% da forma homozigota da hemoglobina S (SS); 16% do tipo hemoglobinopatia SC; e 16%, S-β-talassemia. Em cada paciente, foram realizados anamnese direcionada, exame físico otorrinolaringológico e avaliação audiológica com audiometria tonal, vocal e imitanciometria. Do total da amostra, 37% apresentou alguma alteração na audiometria tonal e a média dos limiares mostrou tendência a ser maior nas altas frequências. Resultados: Na amostra, foram encontrados um paciente (5%) com perda auditiva de grau leve a moderado bilateralmente e seis pacientes (32%) com limiares >25 dB em frequências de 250, 6.000 ou 8.000 Hz em um ou ambos os ouvidos. Não foi observada alteração do Índice de Reconhecimento de Fala (IRF) em nenhum paciente e a imitanciometria mostrou-se com curva Tipo A em 100% dos ouvidos avaliados. A relação do tipo de hemoglobinopatia e a presença ou não de perda auditiva não foram significantes. Conclusão: Assim como descrito na literatura, observou-se, neste estudo, a presença de perda auditiva neurossensorial, principalmente em altas frequências, nos pacientes com DF avaliados. Portanto, conclui-se que é de extrema importância o monitoramento audiológico desses pacientes.

Objetivo: O objetivo deste estudo foi determinar se o encaminhamento de pacientes com dor musculoesquelética crônica para o reumatologista é realizado corretamente. Método: Foram revistas as fichas de encaminhamento para reumatologia do Centro de Saúde Escola de Sorocaba (CSE). Apuraram-se os dados demográficos, clínicos e terapêuticos, os motivos de encaminhamento e a qualidade dos dados. Foram analisados se houve registro das variáveis mencionadas, o tempo de espera para consulta e a qualidade do preenchimento da ficha de encaminhamento. Resultados: Foram analisados 63 guias de referência e respectivos prontuários. A maioria deles é de pacientes do sexo feminino e da faixa etária entre 50 e 70 anos. Em relação às hipóteses diagnósticas, a maior prevalência nas mulheres foi de osteoartrite seguida de fibromialgia, e fibromialgia e artrite reumatoide entre os homens. Dezesseis pacientes não tinham hipótese registrada. A maior parte queixava-se de dor generalizada. Observou-se que um número importante de fichas de referência e prontuários não registrava os medicamentos nem as medidas não medicamentosas. Chamou a atenção o fato de que não houve nenhuma ficha ou prontuário considerado completo. Conclusão: O encaminhamento de pacientes com dor musculoesquelética crônica do setor primário para a especialidade reumatologia tem falhas importantes.
Separatism in South Cameroon: Sources and Prospects
Authors: Denisova T. S. , Kostelyanets S. V.
Published: January 2021

In the 2010s, the issue of separatism in Africa gained special significancein connection with the emergence in 2011 ofa new state – the Republic of South Sudan(RSS), where a military and political conflict has continued throughout the entire period of independent development, accompanied by massive casualties among the civilian population. The situation in the RSSunderscores the weakness of secessionism asa tool for solving the problems of nationalidentity, socio-economic development andpolitical marginalization, and also raisesthe question of whether separatism in Africa is able to lead to stability, an improvement in living standards and an increase inthe level of security of citizens of breakawayterritories.The present paper examines the historical background of separatism in SouthCameroon and of organizations andarmed groups fighting for the separation of the region from the Republic of Cameroonand for the independence of the self-declared Republic of Ambazonia. Currently,the country is engulfed in a military andpolitical conflict, the parties to which arethe central (Francophone) government andthe Anglophone secessionist movements,which include dozens of armed groupswith varying goals and interests and whichfight among themselves for influence on local communities, resources, and the rightto represent Cameroon’s Anglophone minority in the international arena. In fact,South Cameroon is now in a state of war ofall against all.The situation in South Cameroon iscompounded by the fact that President PaulBiya’s government simultaneously has tofend off attacks by Boko Haram terrorists inthe far north of the country and deal with asocio-economic crisis, which is accompaniedby rising unemployment, which, in turn, allows insurgents to expand their ranks withrelative ease. The authors note, however,that the separatists do not enjoy the support of the world community and, unlikemany other African rebel movements, receive hardly any financial or military-technical assistance from outside, which doomstheir armed struggle and increases the consequence of a peaceful agreement with thegovernment.
Legal Acts on the Independence of the Baltic Republics 1988–1990 As a Basis for Modeling the Secession Prevention Mechanism
Authors: Haschina E. E.
Published: January 2021

For modern states, secession is a radical way of resolving the accumulated contradictions between them and the “mother” states, into which they entered for one reason or another. Ever since the adoption of the United States Declaration of Independence in 1776, a kind of tradition of formalizing the secession with a special act of independence has emerged in international law, in which its creators describe the reasons that prompted such a radical decision, declares the supremacy of the legislation of the seceded entity and contains a request for recognition of the sovereignty of the newly formed states from the international community. Analysis of such acts can provide valuable information on the reasons for secession and allow the development of legal mechanisms to prevent it. Within the framework of this work, the acts of independence of the Baltic republics of 1988 – 1990 are considered, adopted during the collapse of the socialist system of Eastern Europe. Being the flagships of this process, Estonia, Latvia and Lithuania in their acts substantiated their choice in the most detailed way, in connection with which the declarations they adopted are of undoubted interest for the researcher. Based on the method of modeling historical processes and the concept of “path dependence”, taking into account the material on the reasons for the secession obtained in the framework of the analysis of acts of independence, an attempt was made to develop a model of “peaceful secession” of the Baltic republics, which would be possible in the case of choosing a different option of behavior at the points bifurcation. The author names the development of a new Union Treaty, reforms of the perestroika period, the choice of the vector of ethno-national policy in the Union republics, the choice of the legal basis and the procedure of secession as the main points of “branching” that open “windows of opportunity” for the Baltic republics. The negative consequences of the current scenario of the development of relations between Russia and the Baltic republics and the advantages of a peaceful resolution of the conflict between the seceding and the “mother” state are described.
