Published: October 2019

A prática docente é, sem dúvida, um dos grandes gargalos para a não efetiva implementação da Lei 10.639/2003 na educação básica. E o currículo representa um dos principais agentes de tal imobilidade. Tomando como princípios a “decifração do conhecimento” e o “alfabetismo da diáspora” (KING, 1996), neste artigo propomos refletir sobre o currículo predominante na educação brasileira e discutir sobre práticas pedagógicas que protagonizem a Educação das Relações Étnico-Raciais. Tomamos como foco de investigação o ensino superior – por meio da análise do componente curricular da disciplina de Educação das Relações Étnico-Raciais (Erer) para os cursos de licenciatura de uma universidade federal – e no ensino médio, a disciplina de Filosofia em uma instituição estadual e outra federal. Nessas análises, incluem-se documentos oficiais e propostas de práticas pedagógicas desenvolvidas durante as aulas nos anos de 2016 e 2018. As contribuições almejadas são especialmente no sentido de desocultar o currículo e propor ações concretas para a valorização de princípios africanos e afro-brasileiros na formação docente.

Espaços públicos como matriz de gestão educacional em Gurupá: resistência política por uma escola popular para o povo
Authors: Santos Emina Marcia Nery dos 
Published: October 2019

Este artigo tem a intenção de demarcar os fundamentos do projeto educacional hegemônico na sociedade brasileira no final do século passado e seu reflexo nas políticas educacionais de Gurupá, município paraense. Investiga de que forma, em contraponto ao modelo hegemônico, o governo municipal traçou possibilidades contra-hegemônicas de se conceber e executar sua política pública em educação. Além da análise de entrevistas semi estruturadas, realizadas em Gurupá, optamos por demarcar um recorte histórico a partir da Constituição Federal de 1988, com realização de pesquisa documental e bibliográfica. As análises feitas nesse artigo demonstram a importância política do processo de municipalização quando concebido como possibilidade de se aproximarem as prioridades de gestão como resposta institucional às reivindicações da sociedade civil, especialmente advindas das camadas populares, qualificando as relações democráticas e participativas entre os agentes envolvidos, respeitando a legalidade da norma e, fundamentalmente instalando outra cultura de gestão alternativa à cultura hierárquica entre os entes federativos. Nesse sentido, concluímos que, em Gurupá, a organização das relações de poder local se organizam a partir de uma racionalidade de resistência, na qual o processo de educação popular, realizado a partir das comunidades eclesiais de base, constitui a base de sustentação dessa dinâmica, que contraria a hegemônica na região, baseada em lógicas clientelistas e patrimonialistas.

Authors: Lopes Thiago Beirigo , Sá Pedro Franco de 
Published: October 2019

Os números decimais integram o cotidiano em experiências comuns como medir, contar, comparar e realizar operações aritméticas. Como exemplo, nos sistemas de medida e monetário adotados em âmbito nacional, números decimais são amplamente presentes. No âmbito escolar, mais especificamente na formação de professores que ensinam matemática, são realizadas pesquisas stricto sensu que envolvem os números decimais. Diante disso, a investigação realizada teve como objetivo analisar teses ou dissertações sobre números decimais, teor e referências, que tiveram como foco a formação do professor que ensina matemática. Foi possível realizar um estudo sobre as teses ou dissertações que cumpriam o escopo, bem como de suas palavras-chave e das publicações utilizadas como aporte teórico, resultando em um mapeamento dessas pesquisas, com o qual foi possível constatar a variedade de objetivos, metodologias e resultados. Ainda, e mais profundamente, foram analisados os principais pressupostos teóricos que embasaram as investigações de mestrado ou doutorado por meio de suas referências, considerando ano, tipo, autor e título dessas.

Authors: Wardhana Yoga Windhu , Priambodo Dradjad 
Published: October 2019

The dissolution of tablets is one of a drug absorption determinant. Disintegrant agent has play an important role on determining the dissolution of tablets. In this experiment, the dissolution behaviours of Acetaminophen and Ibuprofen Tablet was studied using various disintegrant agent such as Low substituted – Hydroxypropyl Cellulose (L–HPC) 21, L–HPC 22 and Sodium Starch Glycolate (SSG) as comparator. Those disintegrant agents were used at three concentration (6%, 7% and 8%) for every tablets formula. Tablets were made by wet granulation method and pressed using single punch 13 mm flat E. Korsch machine. Evaluation of each tablets quality were conducted include for uniformity of weight and size (diameter and thickness), hardness, friability, disintegration time and dissolution. Physically standards from tablets were in good condition, the standards of the weight and thickness uniformity, hardness and friability met the requirement. The dissolution profile on Acetaminophen Tablets showed that only tablet with 6 % L–HPC 21 did not meet the requirement of FI V (Q = 80%, 30 minutes), but on Ibuprofen Tablets where met the requirement of FI V (Q = 80%, 60 minutes) only tablet with 8% L– HPC 21, 7% and 8% SSG. The conclusion of the study was the L–HPC has more disintegrant character at hydrophilic active ingredients.

Measuring muscle tone with isokinetic dynamometer technique in stroke patients
Authors: Dehno Nasrin Salehi , Sarvestani Fahimeh Kamali , Shariat Abdolhamid , Jaberzadeh Shapour 
Published: October 2019

Summary

Study aim: Increased muscle tone, a common consequence of stroke, has neural and non-neural components. Spasticity is related to the neural component. Non-neural resistance arises from passive stiffness. This study was designed to assess the feasibility of using isokinetic dynamometry to evaluate wrist flexor muscle spasticity in stroke patients.

Materials and methods: Twenty-six patients with hemiplegia in the subacute phase of stroke participated in this study. An isokinetic dynamometer was used to stretch wrist flexor muscles at four velocities of 5, 60, 120 and 180°/s on both the paretic and non-paretic sides. Peak torque at the lowest speed (5°/s) and reflex torque at the three higher speeds were quantified. Peak torque at the lowest speed was attributed to the non-neural component of muscle tone, and was subtracted from the torque response at higher velocities to estimate reflex torque (spasticity). Data from the two sides were compared.

Results: There was no significant difference in peak torque between the paretic (2.47 ± 0.22 N·m) and non-paretic side (2.41 ± 0.28 N·m) at the lowest velocity of 5°/s (p=0.408). However, compared to the non-paretic side, the paretic side showed higher reflex torque (p<0001), and reflex torque increased rapidly with increasing velocity (p < 0.05).

Conclusion: The isokinetic dynamometer distinguished spasticity from the non-neural component and showed higher reflex torque on the paretic side compared to the non-paretic side. This instrument is potentially useful to assess the efficacy of therapeutic interventions aimed at modifying spasticity.
Conch structures, soft-tissue imprints and taphonomy of the Middle Ordovician cephalopod Tragoceras falcatum from Estonia
Authors: Pohle Alexander , Klug Christian , Toom Ursula , Kröger Björn 
Published: October 2019

Abstract
Tragoceras falcatum (Schlotheim, 1820) is a common, loosely coiled estonioceratid (Tarphycerida, Cephalopoda) occurring in the Kunda Regional Stage (early Darriwilian, Middle Ordovician) of Estonia. Although the species is quite well-known, we document some features for the first time. For example, one specimen from the Harku quarry (Estonia) with a phosphatized replacement shell exhibits growth halts (megastriae) on the body chamber. As they are not preserved in smaller specimens, we suggest that these megastriae formed at the approach of maturity, possibly also reflecting sexual dimorphism and cycles of reproduction (iteroparity?). Additionally, the specimen shows minute soft-tissue imprints (drag bands and pseudosutures). These imprints are comparable to patterns in other cephalopods such as ammonoids, bactritids and other nautiloids, but have not yet been reported from Palaeozoic nautiloids. However, they might have been misinterpreted as oncomyarian muscle attachment scars previously. Lastly, we discuss the taphonomy of the specimen, which was encrusted by multiple bryozoan colonies post-mortem. Furthermore, it shows questionable traces of bioerosion.

Abstract

Aim. Non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) are in a bidirectional relationship. This prospective study focused on associations between parameters common to the pathogenesis of insulin resistance, inflammation and hepatic steatosis in T2DM patients with metabolic imbalance.

Methods. We used clinical data, insulin resistance and inflammation indices, and hepatic steatosis markers from 120 patients.

Results. The patients (44% men, mean age 58) had a mean body mass index (BMI) of 32 kg/m2 and mean T2DM history of 6 years. With exceptions, significant correlations were found between metabolic, inflammatory and hepatic parameters.

Conclusions. In T2DM patients with poor glycemic control, hepatic steatosis correlates significantly with insulin resistance and inflammation. Increased prevalence and poor prognosis of these diseases together justify the need for NAFLD screening of diabetic patients.
Epidemiological Characterization of Clostridium Difficile Infections in a Rural Community Setting
Authors: Traian Tache , Răzvan Chirică , Marius-Daniel Radu , Sorin Rugină 
Published: October 2019

Abstract
Clostridium difficile is a microorganism - a Gram-positive anaerobic bacterium that has developed and hyperspecialized the ability to form spores. Outside the host, Clostridium difficile germinates spores which are resistant to unfavorable environment and for an extremely long time period. Clostridium difficile infection frequently occurs on a background of major disturbances in the balance of the normal intestinal flora caused by use for therapeutic purposes of broad-spectrum antibiotics. Patients infected with Clostridium difficile in medical facilities are usually elderly people, immunosuppressed or subjected to an antibiotic medication regimen. Wide-scale community use of antibiotics and proton-pump inhibitors induces favorable conditions for the germination of Clostridium difficile spores in the gastrointestinal tract.
Clostridium difficile biocolonizes many domestic and wild animals. Clostridium difficile is a complex bacterium, capable of developing resistance forms that parasitize the gastrointestinal tract of humans, and also many animals. An important source of the Clostridium difficile infection is represented primarily by antibiotic medication administered in communities without medical recommendation, as well as food.

Published: October 2019

Abstract
Porto-pulmonary hypertension (PPH) is the association between portal hypertension (PoH) due to liver disease or extra hepatic etiology and pulmonary hypertension (PH). It’s prevalence ranges between 2 and 16 % (1,2)and it’s diagnosis requires the exclusion of alternative causes of PH which can be sometimes challenging, especially in the context of a wide range of comorbidities that a patient with chronic liver disease can present with. We describe a 72 years-old man with a clinical presentation of right heart failure and signs of severe PH shown by the echocardiography. The blood tests were positive for anti-HCV antibodies and CT-imaging showed signs of cirrhosis and PoH. Complementary exams and review of the literature allowed use to rule out other potential causes constituting the differential diagnosis of the PH in this patient.

Authors: Kosa Arpad , Sciana Beata , Stuchlikova Lubica 
Published: October 2019

Abstract
This article discusses the importance of analytical and experimental approaches in Deep level transient Fourier spectroscopy in terms of reliability, to support the current research and the utilization of this technique for complex investigations. An alternative evaluation approach is proposed and validated by relevant experiments. Attention is focused on a GaAs p-i-n structure, the undoped layer induced defect conduction type statement difficulty, accurate evaluation of a dual type majority-minority carrier defect complex and possible limitations of the DLTS experimental technique. Comprehensive evaluation is carried out and the method is discussed in detail. In comparison with reference data, higher precision of calculated activation energies, differences even lower as 10−3 order of magnitude, were achieved.

Published: October 2019

Abstract
Atomic layer deposited polycrystalline Cr2O3 films grown from chromyl chloride and methanol were analysed using spectrophotometry, spectral ellipsometry and atomic force microscopy. The films possessed polycrystalline eskolaite structure with rough sublayer in contact with air. Using the positions and peak widths of the two visible absorption bands as fixed from absorption measurements, we could determine the optical dispersion of the film material in 1.3 – 6 eV energy region. A direct band gap of chromia film grown in these conditions was 3.2 eV, the other also direct absorption band with a gap of 5.15 eV was found situated in UV.
The Use of the Socio-Cultural Potential of Local Societies through the Presentation of Cultural Specificities
Authors: Krišková Zdena 
Published: October 2019

Abstract
The study is based on the APVV project that focused on the socio-cultural capital of successful Slovak municipalities, bearers of the “Village of the Year” title, which can serve as a source of inspiration for other municipalities in improving the quality of life in the countryside. The aim of this study is to highlight the possibilities for the development of local communities in the context of geographical and economic determining factors and to observe the use of the socio-cultural capital as a source of sustainable growth also in the context of cultural and local identity. The study analyses two concrete examples aimed to increase the attractiveness of the sites through the presentation of their socio-cultural potential. The first case covers the municipality of Hrušov and its participation in the Hont Eco-Museum project, implemented within the wider micro-region. In the second case, we explore the municipality of Spišský Hrhov and its analogical example – the museum of music MuzikMuzeum.
The study was based mainly on the results of the pilot research and subsequent ethno logical field research in both municipalities, conducted predominantly by means of direct interviews with the locals, newcomers as well as leaders of the municipalities in 2018. The synthesis of the conclusions is based on a comparison of some determining factors of the development of both sites (the proximity and accessibility of urban centres, economic or confessional aspects in relation to the local community).
Cage 14: The Orangutan
Authors: Yin Christina 
Published: September 2019

Cage 14: The Orangutan tells the true story of Bullet, the iconic and most well-known orangutan in Sarawak, Malaysian Borneo. The researcher-writer traces Bullet’s story from his infancy when he survives gunshot wounds and is named for the bullet removed from his head by a medical doctor, until his incarceration in Cage 14 at Semenggoh Wildlife Centre. It is the story of an orangutan who, in his youth, mimicked his keepers and forest guards, and who throughout his life, preferred the ground to the trees. This orangutan, who chose to stand upright on two legs with his arms folded across his chest, stands posed in such a way today, stuffed and immortalised in a glass display case at Matang Wildlife Centre where rescued and confiscated wildlife are brought to be treated and rehabilitated. Pieced together from interviews with individuals who interacted with Bullet, this creative non-fiction work is a gothic tale of an orangutan’s life at the mercy of his primate cousins, humans.
