Exploring dicyanamides with two different alkali-metal cations: phase separations, solid solutions and the new compound Rb1.667Cs0.333[N(CN)2]2
Authors: Reckeweg Olaf , Lissner Falk , Schleid Thomas 
Published: March 2023

Abstract
Metathesis reactions designed with the tentative starting stoichiometry (A1)+ : (A2)+ : [N(CN)2]− = 1 : 1 : 2 (A1, A2: Li, Na, K, Rb and Cs) were used to get a complete picture of the compounds and structures that are formed in this regime of dicyanamides with two different alkali-metal cations. Next to solid solutions and phase separations of the respective pseudo-binary dicyanamides, the new compound Rb1.667Cs0.333[N(CN)2]2 was found and structurally characterized as a disorder variety of the KCs[N(CN)2]2 structure. Rb1.667Cs0.333[N(CN)2]2 adopts the monoclinic space group C2/c and the unit-cell parameters a = 1387.73(8), b = 1005.00(6), c = 1451.29(8) pm, β = 117.175(3)° for Z = 8. Its crystal structure is very closely related with those of β-Rb[dca] and KCs[dca]2 ([dca]− ≡ [N(CN)2]−) and so are the vibrational spectra. These three quasi-isostructural compounds are compared in detail. A synopsis of the crystal structures (either already reported or discussed here for the first time) for all combinations in the (A1)+: (A2)+: [N(CN)2]− systems is presented and the behavior of those not forming a distinct compound is discussed.

Published: March 2023

Abstract
The synthesis of beryllium halide etherates and the solution behavior in benzene, dichloromethane, and chloroform was studied by NMR, IR, and Raman spectroscopy. Mononuclear units of [BeX
2(L)2] (X = Cl, Br, I; L = Et2O, thf) were identified as the favorably formed species in solution. Treatment of the mononuclear diethyl ether beryllium halide adduct with one equivalent beryllium halide formed the dinuclear compounds [BeX
2(OEt2)]2 (X = Cl, Br, I). The solid-state structures of [BeCl2(thf)2] and [BeBr2(thf)2] have been determined by single crystal X-ray diffraction analysis. [BeI2(thf)2] decomposed in all solvents. In CD2Cl2 the salt [Be(thf)4]I2 was formed, whereas in C6D6 and CDCl3, BeI2 precipitated and [BeI(thf)3]+, [Be(thf)4]2+ together with the thf ring-opening product [Be(μ
2-O(CH2)4I)I(thf)]2 were observed in solution.
Return to Sport After an Anterior Cruciate Ligament Tear: Bridging the Gap Between Research and Practice
Authors: Arias Roberto , Monaco Jerry , Schoenfeld Brad J. 
Published: March 2023

ABSTRACT
An anterior cruciate ligament (ACL) tear is one of the most frequent injuries experienced by athletes of all levels. Because so many variables are at play, there is a great deal of controversy about how and why this occurs. In addition, there are various suggested appropriate steps to take to return to sport in the fastest and safest possible way. However, a major issue in injury recovery and return to sport practices is the lack of a gold-standard method or a consistent course of action that an athlete should undertake after suffering an ACL injury. Therefore, the purpose of this paper is to review the literature to determine evidence-based methods for return to sport after ACL reconstruction and provide practical recommendations to guide the process.
Nonlinear Theta-Gamma Coupling between the Anterior Thalamus and Hippocampus Increases as a Function of Running Speed
Authors: Qin Yu , Sheremet Alex , Cooper Tara L. , Burke Sara N. , Maurer Andrew P. 
Published: March 2023

AbstractThe hippocampal theta rhythm strongly correlates to awake behavior leading to theories that it represents a cognitive state of the brain. As theta has been observed in other regions of the Papez circuit, it has been theorized that activity propagates in a reentrant manner. These observations complement the energy cascade hypothesis in which large-amplitude, slow-frequency oscillations reflect activity propagating across a large population of neurons. Higher frequency oscillations, such as gamma, are related to the speed with which inhibitory and excitatory neurons interact and distribute activity on the local level. The energy cascade hypothesis suggests that the larger anatomic loops, maintaining theta, drive the smaller loops. As hippocampal theta increases in power with running speed, so does the power and frequency of the gamma rhythm. If theta is propagated through the circuit, it stands to reason that the local field potential (LFP) recorded in other regions would be coupled to the hippocampal theta, with the coupling increasing with running speed. We explored this hypothesis using open-source simultaneous recorded data from the CA1 region of the hippocampus and the anterior dorsal and anterior ventral thalamus. Cross-regional theta coupling increased with running speed. Although the power of the gamma rhythm was lower in the anterior thalamus, there was an increase in the coupling of hippocampal theta to anterior thalamic gamma. Broadly, the data support models of how activity moves across the nervous system, suggesting that the brain uses large-scale volleys of activity to support higher cognitive processes.
“Anhedonia”: um conto cubano em perspectiva multirrede-discursiva na formação de professores de espanhol
Authors: Rabasa Yamilka 
Published: March 2023

Partindo da compreensão da relação constitutiva entre língua e literatura e do poderoso papel da literatura na formação do sujeito, este trabalho pretende inserir-se nas discussões travadas por linguistas aplicados a respeito da inclusão da literatura em planejamentos curriculares na área de formação de professores de espanhol. Mobilizando a Proposta Multirrede-Discursiva (Serrani, 2010, 2020), este artigo apresenta o conto “Anhedonia”, da cubana Mylene Fernández Pintado (2013), a partir de critérios multirrede-discursivos, e discute uma proposta de práticas de linguagens que permitam enfocar, de forma articulada, o tema sociocultural: a mulher (cubana) e sua representação em sociedade, e a heterogeneidade discursiva como tema de língua-discurso, materializada no discurso relatado, sempre visando à formação intercultural de professores de espanhol. Nas oficinas apresentadas estabeleceu-se uma rede semântica a partir de textos em gêneros discursivos diversos com posições diferentes sobre o tema sociocultural em debate, o que pode possibilitar uma melhor compreensão deste e contribuir com uma formação compromissada com a cidadania.

Authors: Torres Vanderli de Lima Vaz , Batista Josemar 
Published: March 2023

OBJETIVO: conhecer a percepção de estudantes de enfermagem em relação à identificação e manejo de pacientes com reações transfusionais imediatas. MÉTODO: descritivo-exploratório de abordagem qualitativa, com aplicação de questionário semiestruturado no mês de junho de 2022 à 15 estudantes de enfermagem numa instituição privada de ensino superior do sul do Brasil. Os dados foram analisados segundo análise de conteúdo, modalidade temática. RESULTADOS: emergiu a categoria: conhecimento de estudantes de enfermagem em relação às reações transfusionais imediatas, constituída por duas subcategorias: fragilidade conceitual para o reconhecimento precoce de sinais e sintomas de reação transfusional imediata; e condutas gerais e específicas na ocorrência de reação transfusional imediata sob a ótica de estudantes de enfermagem. Observou-se incipiência conceitual quanto à temporalidade da reação transfusional, e entre os principais sinais e sintomas relatados destacaram-se a dor e a febre. Embora dois participantes não soubessem relatar nenhuma abordagem/conduta inicial, observou-se que suspender a transfusão imediatamente, solicitar avaliação médica e verificar os sinais vitais foram preponderantes nos depoimentos. CONCLUSÃO: os estudantes de enfermagem apresentam desconhecimento conceitual sobre reações transfusionais, e reconhecem as alterações mais comuns e imediatas indicativas das transfusões, de modo a elencar condutas a serem instituídas pelos profissionais de saúde para minimizar os impactos desses agravos aos pacientes.
O estado regulatório da reprodução humana assistida no Brasil: da ausência de legislação ordinária ao regulamento deontológico atual
Authors: Araújo Ana Thereza Meirelles 
Published: March 2023

Objective: to analyze the legislation and deontological rules in force in Brazil regarding artificial insemination in humans, considering the impact on the rights of those involved. Methods: bibliographic and documentary study using the deductive method, with the aim of critically commenting on the current state of legislation on artificial insemination in humans. Results: the legal framework includes general normative provisions related to the Civil Code, the Biosafety Law and deontological provisions. Together, they provide relevant content but are sometimes insufficient and inadequate for the various circumstances that may be associated with the practice of in vitro fertilization, surrogacy, and postmortem reproduction. Conclusion: based on women's reproductive rights and the autonomy of the parties, it is proposed to reconsider some of the contents regulated in the deontological provisions and to update the legislation.

Os direitos sexuais e reprodutivos da mulher no Brasil na perspectiva do feminismo decolonial
Authors: Souza Iara Antunes de 
Published: March 2023

Objective: to analyze the sexual and reproductive rights of women in Brazil from the perspective of decolonial feminism. Methods: it was a theoretical-dogmatic investigation that aimed to outline, based on legal norms, the sexual and reproductive rights of women and to show these rights, considering intersections, as obstacles to the recognition and exercise of these rights in a decolonial perspective. Results: legal norms were found to be inadequate in hegemonic ways, as socioeconomic and legal issues prevent their implementation for all women. Conclusion: intersectional and diversity factors prevent the exercise of women's sexual and reproductive rights in Brazil, making legal norms insufficient to guarantee rights.

Optimal Multichannel Stretch Factors for Estimating Changes in Seismic Velocity: Application to the 2012 Mw 7.8 Haida Gwaii Earthquake
Authors: Merrill Reid J. , Bostock Michael G. , Peacock Simon M. , Chapman David S. 
Published: March 2023

ABSTRACT
We propose new methods for assessing temporal changes in seismic velocity using the S-wave coda for repeating earthquakes and cross-correlation functions of ambient noise. For a pair of seismic waveforms representing a common source–receiver path, the relative change in path-averaged velocity over the corresponding time interval is directly proportional to the factor by which one waveform needs to be stretched or compressed with respect to the other to achieve maximum coherence. For an arbitrary number of waveforms, initial pair-wise stretch factors determined through standard approaches can be improved through solution of an overdetermined system and further refined through an iterative approach exploiting the singular value decomposition to minimize rank of the stretched waveform section. We apply this combined approach to both repeating earthquakes and ambient noise correlations for Haida Gwaii in western Canada, the site of a Mw 7.8 thrust earthquake in 2012. Optimal stretch factors for repeating earthquake families indicate that path-averaged S velocities dropped by up to 0.16% after the earthquake. Ambient noise correlations indicate that velocities dropped by between 0.26% and 0.39%, which we interpret to be more pronounced in the uppermost levels of the crust. We explore these results in terms of changes in crustal porosity and hydrogeologic conditions by considering the observation that hot spring activity on Haida Gwaii ceased following the 2012 mainshock and recovered over the next several years.
DEVELOPMENT OF EATING ABILITY IN MODERATE INTELECTUALLY DISABLED CHILDREN AT WISMA GONDOSULI 8 BHAKTI LUHUR ORPHANAGE, MALANG
Authors: Karya Gardiana 
Published: March 2023

In everyday life, humans need food, therefore everyone must have eating skills, including children with moderate intellectual disability. This research is focused on children with moderate intellectual disability with the inability to eat independently . This study aims to describe: the ability to develop self-feeding in children with moderate intellectual disability. This research is a qualitative descriptive study. The research subjects are two intellectually disabled children in grade 2 SDLB who live in Bhakti Luhur Orphanage, Malang. Data collection was carried out by observation (participant) because the researcher lived with the children and the data was documented. The steps of data analysis used descriptive qualitative analysis, namely presenting data in narrative form. The results showed that the ability to develop self-feeding in moderate intellectual disabled children was still in the moderate category because it still needed further assistance and training. Suggestions for companions to remain patient and diligent in training the abilities of moderate intellectual disabled children to train them repeatedly in the same way until children have eating skills.

Macroeconomia e Especificidade Camponesa: Uma hipótese baseada em eficiência reprodutiva para a dinâmica dos investimentos na agricultura dos Estados Unidos (Paper 188)
Authors: Costa Francisco de Assis 
Published: March 2023

É matéria de pouca controvérsia que as variáveis de investimento - investimento bruto (gastos em estruturas, máquinas, equipamentos e inventários - IB) e investimento líquido (IB menos depreciação e baixas - IL) – são procíclicas em relação ao Produto Nacional Bruto – PNB2. Barro (1993:11-13) apresenta a evolução das componentes cíclicas das duas variáveis3, constatando, para os Estados Unidos, a alta correlação (R2 = 0,91) entre os movimentos ondulatórios do Investimento Bruto e do Produto Nacional Bruto. Ademais, seus dados demonstram ser esta a mais alta correlação entre todos os componentes do PNB (idem: 9). Por outra parte, a volatilidade do IB (desvio padrão de 0,082) é quase cinco vezes a do PNB (desvio padrão de 0,017), dando consistência à conclusão de que os investimentos são forte fonte de flutuações no estado geral dos negócios.

A Regulação da Água no Brasil: Quando o Domínio Público era um Pressuposto Inovador (Paper 208)
Authors: Ravena Nírvia 
Published: March 2023

A regulação de recursos hídricos no Brasil remonta ao Código de Águas de 1934. Esse Código, o primeiro modelo regulador de recursos hídricos no país, foi um instrumento dotado de contornos regulatórios inovadores dado o arcabouço institucional no qual foi gerado. A regulação atual tem origem e propósitos distintos do primeiro arcabouço constante do Código de Águas de 1934, mas é ainda resultado das formas de organização que operaram na sua implementação. As trajetórias dependentes desse processo ainda operam nos processos de regulação da água no Brasil.Palavras-chave: Água. Regulação. Instituições.
