Do Haiti ao Planalto: os militares e a relação com a ONU no primeiro ano do governo Bolsonaro
Authors: Campos Tales
Published: March 2022

This article aims to analyze the relations between the UN and Bolsonaro government in 2019 in the scope of foreign policy –considering the importance that the United Nations Stabilization Mission in Haiti (MINUSTAH) has for the Armed Forces and the international projection of Brazil. The methodology used in this article consists of bibliographical research relating primary and secondary materials (theses, articles, and dissertations) with recent journalistic material on federal management. The result found in this article demonstrates that, despite the divergence between sectors of the federal government regarding the directions of Brazilian foreign policy, due to issues of realignment at the international level, the approximation of the viability of relations with the UN through peace missions it’s not present in the plans of the Executive and the Armed Forces, although the military has prestige for this type of operation.
Back to basics: assessing military involvement in politics in contemporary Brazil
Authors: Vitelli Marina
Published: March 2022

As Brazil showed signs of progress in civil-military relations in the late nineties and early 2000s, research moved from civilian control to defense policy topics, resulting in the neglect of less obvious forms of military involvement in politics, many of which pre-date the presidency of Jair Bolsonaro. After critically reviewing existing frameworks for assessing progress in civilian control we propose returning to the field’s primary concern with military intervention in politics by using three indicators -military presence in government; public commentary by military officers; and episodes of military contestation –and their implications regarding the armed forces, politicians, and society. Next, we examine these three indicators in the context of the presidencies of Dilma Rousseff and Michel Temer. We conclude that interactions between “soldiers, politicians, and civilians” in recent episodes of military involvement in politics revealthe full extent of the frailty of civil-military relations in Brazil.
Música Popular Black and anti-racist struggles: musical cosmopolitanism and the soul aesthetic in Brazil (1963-1978)
Authors: Treece David
Published: March 2022

This essay reassesses the political significance of the creative impulses, performance aesthetics and artistic work that became identified collectively as Música Popular Black, and their contribution to the anti-racist cause in Brazil during the 1964-85 dictatorship. It re-evaluates how the state orthodoxy of racial nationalism and denialism was challenged, not merely in the adoption of the soul aesthetic as a marker of diasporic identification with US Blackness, but in the cumulative emergence of an autonomous anti-racist consciousness and voice for Afro-Brazilians within their ownmusical and social world. This was expressed, not only in a body of powerfully explicit anti-racist statements but also in a creolized, cosmopolitan idiom of vocal and performative style that connected local artists and the Black Rio dance scene, and that contributed to the building of a Black public sphere, leaving a potent legacy for the musical and political movements of the 1980s, 1990s and beyond.
Gênero e defesa: uma questão de preferências
Authors: Schwether Natalia , Steiner Andrea
Published: March 2022

The article aims to answer the question: what explains the absence of gender policies in official Brazilian defense documents? Therefore, it suggests that such absence is also a result of military influence in politics. That is, the challenges faced by Brazilian military women, such as limited access to certain weapons and specialties, restrictions on forms of entry, infrastructure problems and the lack of legislation to support them, are reflections of the interests of political elites and their relationship with the military leaders, who do not always have the political will to put the issue of gender on the agenda, striving to keep the organization unscathed from social changes. The article employs the process tracking technique, with a special focus on the search for empirical evidence.
The Role ofPsychedelics in Managing Anxiety, Depression, and Flashbacks of Individuals withPost-Traumatic Stress Disorder
Authors: Hammel Reace L. , Gulliver Berry J. , Sukich Shelby N. , Abraham Samuel P.
Published: March 2022

Background: The impact of psychedelic treatment on patients with posttraumatic stress disorder (PTSD) has become more intriguing to the psychiatric field. Because of the stigma surrounding illicit drug use, the scientific communities were unable to conduct thorough studies regarding the effects of psychedelics on the brain. These drugs could help many people with mental illnesses that have not found adequate success with typical treatments. In recent years, there have been studies conducted to examine the use of psychedelics for the treatment of psychiatric disorders such as PTSD. Purpose: The purpose of this review was to bring awareness to the effectiveness of long-forbidden psychedelic treatments such as psilocybin. Method: Using a review of scholarly articles, this paper examines the effects of psilocybin on anxiety, depression, and flashbacks in patients with PTSD. Findings: Findings indicate a therapeutic effect on patients with PTSD when using psilocybin. Conclusion: Based on these findings, the medical community should take steps toward novelty treatments for psychiatric diagnoses; however, further studies may be implicated. Stigma against this class of medications remains an issue.
A Comparison Review of Mechanical Cardiopulmonary Resuscitation Vs Manual Cardiopulmonary Resuscitation
Authors: McIntosh Briana W. , Miller Kayli N. , Carmack Samantha R. , Abraham Samuel P.
Published: March 2022

Background: Cardiopulmonary resuscitation (CPR) is a lifesaving intervention performed by healthcare workers in the event of cardiac arrest. In recent years, many mechanical devices have been developed to perform quality compressions in place of manual chest compressions in an attempt to sustain quality CPR, as the rescuer will tire, and CPR quality will diminish. With the rise of mechanical cardiopulmonary resuscitation devices (LUCAS, Zoll AutoPulse) making mechanical CPR a realistic and practical treatment option, it now must be determined whether or not mechanical CPR leads to better outcomes in patients that have been successfully resuscitated in comparison to patients having been resuscitated by manual compressions, as is seen in traditional CPR. Purpose: The purpose of the review was to compare long-term outcomes of patients receiving mechanical cardiopulmonary resuscitation versus manual chest compressions. Method: This is a systematic review of the nursing-focused literature regarding the complications and long-term outcomes of patients receiving both manual and mechanical cardiopulmonary resuscitation. This review examined evidence-based studies of both methods to compare findings. Findings: This review found achievement of return of spontaneous circulation (ROSC), complications, and chest compression quality, that pertained to the outcomes of patients following cardiac arrest. No significant difference was noted in the outcomes. Conclusion: At this time, mechanical CPR has more benefit to the team of rescuers than to the patient receiving CPR, as it reduces the number of people needed to make resuscitation efforts and reduces loss of compression quality from fatigued rescuers. However, mechanical CPR was not found to have better patient outcomes when compared to manual CPR in cases of out-of-hospital cardiac arrests.

Authors:   Nizhnevartovsk State University, Sushkov V. V. , Revyakin E. E. ,   Industrial University of Tyumen
Published: March 2022

In this paper, the synchronous generator shaftposition control system for synchronization process is explored. When the standard synchronization method is applied closing of a circuit breaker is accompany by the transient effects. This happens due to the voltage frequency of the synchronized generator is not equal to its synchronous value when the phase angle is controlled. The proposed synchronization approach allows to reduce the transient process influence on electrical equipment and improves the maneuverability of the control system in comparison with the standard method. Simulation modelling results are provided to illustrate it.

The first Russian newspaper in Shanghai (1918–1921)
Authors:   Shanghai, China, Sun Yizhi
Published: March 2022

This paper deals with the history of first Russian newspaper in Shanghai: Russian section of «Shanghai Gazette». With a detailed analysis of this newspaper, I have succeeded in identifying five editorial staffs of the Russian section: the first SocialRevolutionary staff, the Bolshevik staff, the White Army staff, the second SocialRevolutionary staff and the Monarchic staff. The author concluded that the editorial staffs of Russian section don’t follow a policy of the Editor-in-chief Chen Youren, colleague of Dr. Sun Yat-sen. At that time the members of Kuomintang couldn’t clearly know about the political situation of Russia, and from 1918 to 1920 there were very few people in China who knew the Russian and could translate Russian articles into Chinese. This is why the Editor-in-chief Chen Youren hadn’t notice that there were a large number of anti-Bolshevik elements in his Kuomintang newspaper.

A translation of an article by the great British philosopher Bertrand Russell on the conceptualisation of the philosophical foundations of epistemology is presented. It formulates key definitions and justifies the methodological principles on the basis of which will be possible to construct theories consistent with the ideas of empiricism and the concept of knowledge by acquaintance. Drawing on concrete examples as well as the theses on the logical conditioning of the methods of cognition, Russell lays the foundation for the theory of neutral monism, which became the basis of his epistemological ideas in the early period of his work.

Published: March 2022

Decomposition of β,γ-unsaturated diazoketones has been investigated in the presence of Rh2(OAc)4 catalyst. These reactions produce exclusively the products of the vinylogous Wolff rearrangement with higher yields than CuII catalysts. Chiral catalysts such as tetrakis [methyl (S)-5-oxopyrrolidine-2-carboxylate]dirhodium(II) and CuI bis(oxazoline) complexes, which are effective catalysts for the inter and/or intramolecular cyclopropanations reactions, catalyze the vinylogous Wolff rearrangement to produce the expected products with low levels of enantioselectivity.

Published: March 2022

The flexible bidentate ligand 1,3-bis(benzimidazol-2-yl)propane, L3, and its N-methylated derivative L4, form complexes with CUI and CUII. The X-ray crystal structure of [Cu(L4)(MeCN)] (PF6) (1) shows a trigonal coordination of the CuI with the eight-membered chelate ring adopting a half-chair conformation. With CuII in EtOH, L3 forms dimeric [(L3)Cu(μ-EtO)2Cu(L3)](ClO4)2 · 2EtOH (2) whose X-ray crystal structure shows CuII in a distorted square-planar environment with one bidentate ligand and two bridging ethoxides. The chelate ring now has a boat-chair conformation which forms a hydrophobic pocket around the metal.

Published: March 2022

Microalgae can be used for diverse applications in research and industry. Several microalgae grow adhering to surfaces that are usually two-dimensional. A third dimension could increase the amount of microalgae adhering to a given area and can be offered by textile fabrics. Here we report on the microalgae Chlorella vulgaris and Scenedesmus spec. growing on different knitted fabrics under defined light and under office light conditions. Our results show a significant influence of illumination on both algal species and a smaller impact of the chosen medium, while all knitted fabrics under examination were found well suited as substrates. The numbers of alga cells per petri dish were higher on textile fabrics than in pure water or medium by a factor of ~ 4–20, respectively.

Based on Socio-economic Field Laboratory concept, we put forward the need to amplify locally-embedded innovation to address nationwide challenges. The WoodCluster project (2017-2021) aimed to seek solutions to close the national wood supply gap based on farm-wood production in East African countries. Towards achieving the objective, one of the project activities is the implementation of Field School. A field school is understood as a practical element of a thematic study course module, supplementing theoretical teaching. It shall provide the opportunity for students to learn and test research methods in a practical manner and get in contact with the local community to exchange knowledge. It serves as a framework that requires adaptation to the local research demand and context, with its cultural, socio-economic, and environmental features. Two field schools within the framework of the project were conducted in Tanzania in 2018 and in Ethiopia in 2019. The focus of the field school was on local-level wood production from smallholder farmers and market dynamics, but the guideline can be adapted to other thematic areas. Based on the experiences within the WoodCluster project in East Africa, this guideline elaborates the theoretical fundaments, steps, methods, and examples in conducting socio-economic field schools with local communities and graduate students.

To achieve these objectives, the researchers used the descriptive method using a survey as well as a comparative method. The research sample consisted of (390) male and female students who were chosen in a deliberate way, in a pairing style, from the colleges of the University of Duhok for the academic year (2019-2020). The Arabic version of Harrison and Bramson scale was used. And the data was statistically processed using (mean, standard deviation, t-test for one sample and independent-samples, one-way analysis of variance (ANOVA), less significant difference (L.S.D) test, and Pearson Correlation Coefficient). The results of the study showed that the most common thinking style was the realistic thinking style, and the least common method was the synthetic method among students who practice sports and those who don’t. It was found that there is a statistically significant difference in the style of realistic thinking among students who practice sports and those who don’t. there is a statistically significant difference in the methods of thinking (synthetic, ideal, practical, and realistic) attributed to the variables of age. And there is a statistically significant difference in the method of practical thinking attributed to the academic specialization (scientific, literary) and in favor of the literary specialization.

The current study aimed to identify the practicing Level of Formative Evaluation among high school science teachers and its methods in teaching science from the point of view of the teachers themselves, to achieve the study objectives, the qualitative approach was followed by using the observation card for the practicing of (6) science teachers for six methods of formative evaluation to measure aspects of different learning outcomes. These methods of study included: direct class questions, discussion, assignments and performance tasks, formative tests, observation, and applications. The results of the study showed that the discussion method was the most widely used among the formative evaluation methods, followed by the class questions, and that none of the six teachers used the two methods: observation or practical applications. The practices were common, and the female teachers did not use participatory evaluation methods, and they did not use self-correcting tests except for one parameter, and they did not record any evaluation activities in which peer evaluation was used. The results showed that the level of female teachers’ practices of formative evaluation methods sometimes agreed with their level of knowledge of these methods, and in other times the practices were at a lower level than female teachers’ knowledge of these methods, and the level of secondary school science teachers’ practice of evaluation methods was rarely higher than their knowledge of them. In light of these results, the researcher recommended several recommendations, the most important of which are: training female teachers to practice the methods of formative evaluation, and to include practical applications of formative evaluation within the teacher preparation programs in the faculties of education in Saudi universities.

Systemic Lupus Erythematosus (SLE) is a chronic, relapsing, and remitting systemic disease. Autoimmunity and protean clinical manifestations affecting almost all the systems are the hallmarks of SLE. Systemic lupus can affect the central nervous system. The severity of CNS manifestations varies from less severe subclinical neurocognitive dysfunction affecting memory, intellect, and learning to more severe manifestations such as seizure, stroke, or transverse myelitis [1]. The psychotic features of primary psychiatric disorders overlap with Neuropsychiatric SLE (NPSLE) and often mask and delay the diagnosis of NPSLE.
