A luta dos movimentos socioterritoriais camponeses pelo direito à Educação do Campo
Authors: Camacho Rodrigo Simão 
Published: April 2021

Toda a legislação que foi sancionada a respeito da Educação do Campo é conquista de todo o Movimento da Educação do Campo, que envolve, além dos movimentos socioterritoriais camponeses, várias organizações sociais, universidades e educadores do campo (formais e não formais), representados, sobretudo, primeiramente, pela Articulação Nacional Por uma Educação do Campo e, atualmente, o Fórum Nacional da Educação do Campo (FONEC). A primeira conquista da Educação do Campo, enquanto política pública, foi o Programa Nacional de Educação na Reforma Agrária (PRONERA), que é uma política pública de Educação do Campo desenvolvida nas áreas de Reforma Agrária. A metodologia do artigo está dividida em duas partes principais. A primeira é a análise da legislação e de documentos oficiais relativos à Educação do Campo. A segunda está relacionada com a entrevista de camponeses-assentados-educandos do Curso Especial de Geografia do Pronera (CEGeo).
Cadastro ambiental rural
Authors: Silva Gregory de Assis Ribeiro da , Campelo Maria Jaciane de Almeida 
Published: April 2021

O Cadastramento Ambiental Rural - CAR facilita o proprietário legalizar sua área, não necessitando essencialmente do georreferenciamento, com a possibilidade de cadastramento sem o uso de geoprocessamento. Para a realização do referido estudo foi feita uma prospecção com sistema geodésico e uso do georreferenciamento, com posterior inserção dos dados na plataforma digital do INCRA. O estudo compreendeu o período de outubro de 2018 a maio de 2019, na fazenda Jacumuazinho, Mirangaba (10°55'52"S 40°33'76''W), um fragmento de Floresta Estacional Semidecidual, domínio fitogeográfico da Caatinga, Sertão Baiano. Os dados revelaram que pelo tamanho da Fazenda Jacumuazinho, a mesma se encontra obrigatoriamente apta a fazer o georreferenciamento. Com isso, sua certificação foi feita através de um profissional credenciado no INCRA e certificada na plataforma do SIGEF, gerando o mapa e o memorial descritivo, com a certificação da parcela georreferenciada do referido imóvel. Com base nisso, a propriedade foi dividida em duas partes, gerando dois polígonos e dois CAR. Nota-se que a aplicabilidade do CAR possui vantagem relacionada ao mercado de cotas de Reserva Legal (RL), considerado um beneficio agregado ao cadastramento em que há troca de informações e de imagens de cobertura vegetal, podendo ser usadas para compensar a falta de Reserva Legal (RL). Ademais, é uma ferramenta que serve como fonte de renda alternativa para quem cria, arrenda ou vende as cotas, colaborando para quem precisa regularizar sua propriedade.

Abstract
MIL-125(Ti) metal–organic framework-derived nanoporous titanium dioxide–heteropoly acid (PW–TiO2) have been synthesized by a facile hydrothermal approach and subsequent calcination, and the PW–TiO2 catalysts were investigated using various characterization technologies including FTIR, XRD, SEM, TEM, N2-physisorption, and NH3-TPD. Further, we investigated the use of PW–TiO2 composites as heterogeneous acid catalysts for the catalytic esterification of oleic acid. Among all series of catalysts, the calcined PW–TiO2 at a temperature of 350°C showed excellent activity with a high conversion of 90.5% at 160°C for 4 h. More importantly, the catalyst could be simply separated via centrifugation and reused for six cycles and shows a relatively high conversion of 74.8%.

Published: April 2021

Abstract

Objectives
Cardiovascular diseases (CVDs) are highly prevalent in various countries, and heart failure accounts for the majority of deaths. The present study focuses on determining the protective effect of ethanol extract of leaves of Tamarindus indica (TIEE) by in vitro and in vivo methods.

Methods

In vitro cardiotonic activity was determined using Langendorff’s heart perfusion assembly. In vivo studies were performed using Doxorubicin (1.5 mg/kg, i.p for seven days) induced cardiotoxicity in rats. These animals were simultaneously treated with the TIEE at a low dose (200 mg/kg, p.o), high dose (400 mg/kg, p.o) and standard drug Digoxin (100 μg/kg, p.o) for seven days. At the end of the study, various parameters like electrocardiogram (ECG) recording, serum levels of serum glutamic pyruvic transaminase (SGPT), lactate dehydrogenase (LDH), creatinine phosphokinase (CPK), and presence of cardiac troponin (cTnI) were determined. Isolated hearts were subjected to histopathological studies.

Results
The TIEE at a concentration of 60 μg/mL showed a significant cardiotonic effect in vitro that was evident by increased force of contraction, heart rate, and cardiac output. In vivo studies revealed that the TIEE decreased the prolongation of QT and RR interval of ECG, lowered the serum enzyme levels like LDH, CPK indicating cardiac protection, and the same was established by the absence of cTnI in blood. Histopathological examinations of heart tissue sections showed improved architecture in the treatment groups when compared with diseased groups.

Conclusions
The study revealed the cardioprotective activity of T. indica leaf extract by both in vitro and in vivo methods.

Published: April 2021

Abstract
In literature, various mathematical models have been developed to have a better insight into the transmission dynamics and control the spread of infectious diseases. Aiming to explore more about various aspects of infectious diseases, in this work, we propose conceptual mathematical model through a SEIQR (Susceptible-Exposed-Infected-Quarantined-Recovered) mathematical model and its control measurement. We establish the positivity and boundedness of the solutions. We also compute the basic reproduction number and investigate the stability of equilibria for its epidemiological relevance. To validate the model and estimate the parameters to predict the disease spread, we consider the special case for COVID-19 to study the real cases of infected cases from [2] for Russia and India. For better insight, in addition to mathematical model, a history based LSTM model is trained to learn temporal patterns in COVID-19 time series and predict future trends. In the end, the future predictions from mathematical model and the LSTM based model are compared to generate reliable results.
The degree zero of digital interfaces: a semiotics of audiovisual archives online
Authors: Treleani Matteo 
Published: April 2021

AbstractInterfaces have partially replaced editors. They now administer and have industrialized the processes of content circulation. Web platforms mediatize cultural memory and one example of this is that of online audiovisual archives which are a paradigmatic case involving interfaces mediating our image of the past. Therefore, their role as an enunciative framework is clearly worthy of thought and study. We will thus use a semiotic approach based on the starting hypothesis that digital interfaces shape our belief systems through a discursive framing of content to which they give access. By analyzing two case studies, we will argue that the transparency of interfaces appears to recall the notion of “mechanical objectivity” and thus refashion the reliability of the archives. However, a final counter-analysis of a document read in the framework of an on-site consultation invites us to reshape our considerations and enlarge the perspective from semiotic visual analysis to include the social processes linked to the publication of digital heritage.

Published: April 2021

Academic writing articles serve as the medium of communication among scholars to share knowledge and new inquiries and are made in such a way that the idea they deliver is both understandable and accepted. One essential action to accomplish this is by employing metadiscourse markers. Metadiscourse is viewed as an essential element of credible written texts created by students of ESL and native speakers, by which the intelligibility of communication in research articles can be accomplished through suitable discipline conscience, norms, and belief to track the writers’ pathway to academic promotions. Therefore, employing descriptive qualitative approach, this study aims at investigating the utilization of interpersonal metadiscourse markers and their functions in academic writing. Analysing discussion section of research articles written by Indonesian expert writers, the results show that the metadiscourse markers in the articles are found to be similar to the commonly used markers among academic community, including interactive and interactional markers. Moreover, the employment of markers in the articles reveal the functions of them to indicate relation between sentences, involvement of readers, existence of example, limitation of commitment to propositions, emphasis on general practice and certainty, and reference to the writer.
HIGHLGHTS:

The appropriate utilization of interactive and interactional metadiscourse markers in research articles indicates the international norm of academic writing.
The Indonesian expert writer articles fulfill the intelligibility of communication in international research articles.
The writing course in the universities needs to emphasize the essential functions of metadiscourse markers.

Published: April 2021

Abstract
The use of nanomedicines for cancer treatment has been widespread. Fullerenes have significant effects in the treatment of solid tumors. Here, we are going to study the effects of hydroxylated fullerene C60(OH)n(n = 18–22) treatment on chronic myeloid leukemia cell proliferation and investigates its toxicity. The results show that fullerenol at low concentrations (< 120µM) is no apparent toxic side effects and stimulates the growth of K562, while a high concentration of fullerenol has different degrees of inhibition on K562 cells. When the concentration is higher than 160µM, the K562 cells showed morphological changes, the mitochondrial membrane potential decreased, the cell cycle was blocked in the stage of G2, and cell apoptosis occurred, which may cause apoptosis, autophagy, and a variety of other damage leading to cell death. Meanwhile, it also indicated that its inhibition of solid tumors might be related to the tumor microenvironment; we verified the safety of fullerene without apparent cellular toxicity at a specific concentration.

Abstract
Erythema Nodosum Leprosum (ENL) is an acute and systemic inflammatory reaction of leprosy characterized by painful nodules and involvement of various organs. Thalidomide is an immunomodulatory and anti-inflammatory drug currently used to treat conditions such as ENL and multiple myeloma (MM). Cereblon protein was described as the primary target of thalidomide teratogenicity. Moreover, it was postulated that CRBN is necessary for the efficacy of thalidomide and its analogs in the treatment of MM. In this study, we evaluate the influence of CRBN genetic variants on the dose of thalidomide used in the treatment of ENL and on the manifestation of adverse effects during treatment for ENL. Polymorphisms rs1620675, rs1672770 and rs4183 located in regions flanking the part of the gene encoding the portion of the protein that binds to thalidomide were evaluated. An association with adverse ocular and gastrointestinal effects was observed. These results show that CRBN polymorphisms could alter the expression or activity of the protein and influence the development of adverse effects in response to thalidomide in ENL.

Published: April 2021

Abstract
Increasing transistor switching time and rising count of transistors integrated over a chip area has given a high pace in computing systems by several orders of magnitude. With the integration of circuits, number of gates and transistors are increasing per chip area. CMOS Logic family is preferred due to its performance and impeccable noise margins over other families. However with integration in every digital circuit, the energy due to switching of gate doesn’t decrease at same rate as gates are increased per chip area. Due to this, power dissipation becomes significant and also reduction of heat becomes more complicated and expensive. In CMOS based circuits dynamic power requirement is becoming major concern in digital circuits. In this paper, the work is focused on reducing the power dissipation in circuits which is increasing with down scaling of circuits. The work is done on 2:1 multiplexer and full adder circuit. Adiabatic logic with positive feedback (PFAL) is applied to redesign the circuit with input power taken as sinusoidal source of 3.3 V and analysis is done for power dissipation between conventional CMOS and PFAL based CMOS circuits. In comparison with the conventional CMOS 2:1 multiplexer circuit, the designed PFAL CMOS 2:1 multiplexer circuit has less power dissipation as 80.871 picoWatts while conventional CMOS circuit has 6.9090 nanoWatts with the same behavior of circuit. Also for full adder conventional CMOS circuit have 48.0452 picoWatts while PFAL based full adder has 3.9089 picoWatts.
Tetracycline Degradation in the UV-heterogeneous Fenton-like System With BiFeO3 Catalyst

Published: April 2021

Abstract
Surplus tetracycline (TC) in the water body causes damage to the ecology balance and human health. Therefore, an efficient strategy was proposed, namely, the UV-heterogeneous Fenton-like system with BiFeO3 (BFO) catalyst, to eliminate TC pollution. This work successfully integrated the photocatalytic oxidation system with the heterogeneous Fenton-like system, cooperating with the photolysis of H2O2. These coupled effects could boost the reduction of Fe (Ⅲ) to Fe (Ⅱ) and depress the recombination of photogenerated charges, further promoting the generation of reactive species, and ultimately facilitating the TC degradation and mineralization. The catalytic of the prepared BFO was stable with no secondary pollution, and BFO could be recovered by an extra magnet to reuse. Compared with other advanced oxidation processes, this system showed an outstanding performance in TC degradation and mineralization, and TC and TOC removal efficiencies could reach 100% and 74.92%, respectively. Moreover, the possible mechanisms for TC degradation involved that TC was degraded by oxidation species generated by the synergistic effect in this system, such as superoxide radicals (·O- 2), hydroxyl radicals (·OH), and positive holes (h+). Intermediate products in the TC degradation process mainly were products at m/z=459, m/z=445, and m/z=134.

Authors: Caruana Erin , Rowell David , Kuys Suzanne , Brauer Sandra G. 
Published: April 2021

Abstract
Background This study aims to investigate the impact of multidisciplinary Saturday rehabilitation (MSR) on length of stay, functional independence, gait and balance when compared to a 6-day physiotherapy-only service in a pragmatic setting. An economic evaluation of the intervention conducted from the perspective of the healthcare provider is included.Methods A prospective cohort study with a historical control was conducted in an Australian private mixed rehabilitation unit to compare a multidisciplinary and physiotherapy-only 6-day rehabilitation service. Clinical outcomes included the Functional Independence Measure (Motor, Cognitive, Total), gait speed (10 Meter Walk test) and five balance measures (Timed Up and Go test, Step test, Functional Reach, Feet Together Eyes Closed and the Balance Outcome Measure of Elder Rehabilitation). Economic outcomes were rehabilitation unit length of stay and additional treatment costs.Results A total of 366 patients were admitted to the rehabilitation unit over two 20-week periods. The prospective cohort (MSR) had 192 participants and the historical control group (physiotherapy Saturday rehabilitation) had 174 participants). Participants in the historical control group had lower total and cognitive Functional Independence Measure scores (p < 0.078), and generally performed at a lower level on admission gait and balance measures compared to the prospective cohort. More participants in the prospective cohort attended weekend therapy, attending more sessions and spending more time in therapy compared to those in the historical control group (p < 0.012). After controlling for differences in admission Functional Independence Measure scores, length of stay was reduced by 1.39 ± 0.77 days. The economic evaluation estimated cost savings of $1,536 per patient. The largest savings were attributed to neurological patients $4,854. Traumatic and elective orthopaedic patients realised cost savings per admission of $2,668 and $2,180, respectively.Conclusions Implementation of MSR results in a more efficient service, enabling a greater amount of therapy to be provided over a shorter length of stay. The provision of a multi-disciplinary Saturday rehabilitation is potentially cost reducing for the treating hospital.Trial registration not applicable.

Published: April 2021

Abstract
Background

The nurses are at the forefront of patient care during an infectious disease pandemic, and play a key role in treating and preventing the upward trend. Hence, it is crucial to consider their experiences in designing action plans to combat coronavirus disease 2019 (COVID-19). Since there is not enough data in this regard, the current study aimed to investigate the nurses' experiences in caring for patients with COVID-19 in Iran.
Methods

Taking a conventional content analysis approach, this qualitative research included 20 nurses working in the public hospitals affiliated to Tabriz University of Medical Sciences, Iran. To collect data, semi-structured interviews were conducted and analyzed using MAXQDA10 software.
Results

Data analysis revealed four main themes including ‘duality in the form of care’, ‘bewilderment and ambiguity in care planning’, ‘workload’, and ‘positive image with social isolation’.
Conclusion

Findings indicated that the nurses provide nursing care in stressful conditions while confronting various paradoxes. The results could lead to a clear understanding among the country's healthcare managers and policymakers to take appropriate measures to support the nurses and improve nursing care quality during the COVID-19 pandemic.
