O movimento antropofágico e o direito dos povos indígenas: a arte enquanto instrumento de redimensionamento de direitos
Authors: Gonçalves Douglas Oliveira Diniz , Linhares Hannah Silva
Published: January 2023

No ano em que o movimento antropofágico, inaugurado na semana de arte moderna, completa 100 anos, a constatação do cenário atual em relação às violações de direitos dos povos indígenas é intrigante. Os povos indígenas no Brasil sofreram e continuam a sofrer inúmeras violações a suas culturas, organizações, territórios e corpos. As marcas históricas deixadas durante os anos de formação nacional foram escarificadas na sociedade brasileira a partir de uma perspectiva dominante de viés cultural, econômico e jurídico contrária aos povos indígenas. Nesse sentido, o objetivo da presente investigação é analisar, a partir da articulação entre direito e arte, a viabilidade do movimento antropofágico como perspectiva propiciadora da consolidação dos direitos indígenas no Brasil. A partir daí, levanta-se a hipótese de que: mediante as possibilidades de implicações entre direito e arte, o movimento antropofágico se revela enquanto instrumento de redimensionamento da luta em prol dos direitos dos povos indígenas no Brasil. A estrutura metodológica se instrumentaliza através da análise do potencial das artes como via de questionamento e materialização de direitos.

The aims of this study were (i) to evaluate the performance of the Assurance® GDS method combining immunomagnetic separation and Real Time PCR for STEC detection in pooled samples (up to 375g) of vegetables and meat and (ii) to compare its performances to that of the reference method ISO/TS-13136:2012 (25 g sample size) in artificially contaminated samples.
The alternative Assurance® GDS method includes enrichment in proprietary broth at 41.5ºC for 10 h followed by primary screening of TOP 7 STEC containing eae, stx genes and O157:H7 markers using MPX-Top 7 (IMS+PCR), secondary screening for serogroup identification using MPX-ID/EHEC-ID (IMS+PCR). And finally, cultural confirmation from same IMS beads on two selective agars is set up. For reference method, the enrichment was performed in BPW at 41.5ºC for 18 h. A total of 120 samples of meat and vegetables, including 20 uninoculated and 100 samples spiked with stressed cells (<12 CFU/25 or 375g) of STEC, were analyzed using both methods.
Our results showed that the Assurance® GDS method LOD50 ranged from 0.12 CFU/375 g to 0.522 CFU/375 g and the LOD95 from 0.518 CFU/375 g to 2.257 CFU/375 g. These data are similar to the LOD50 data of the reference method.

Authors: Atipatyakul Piengkwan , Chen Yun-Fang , Yao Chuan-Fong , Chen Ying-An , Chen Yi-Hsuan , Liao Yu-Fang , Chen Yu-Ray
Published: January 2023

Background
This study (1) evaluated the stability of the maxillary and mandibular proximal and distal segments after surgery-first bimaxillary surgery for class III asymmetry and (2) determined whether the stability of a given mandibular segment was related to the movement of any segment during surgery or postsurgical stability of any other segment.
Methods
Seventy adults with class III asymmetry consecutively corrected through surgery-first Le Fort I osteotomy and bilateral sagittal split osteotomy were investigated. Cone-beam computed tomography imaging performed before treatment (T0), 1-week after surgery (T1), and after all treatment (T2, ≥1-year after the surgery) was used to assess skeletal movement during surgery (T0 to T1) and postsurgical skeletal stability (relapse, T1 to T2) regarding the translation and rotation of the maxillary, mandibular distal, and proximal segments. Stepwise regression was performed to evaluate the relationship between the stability of a given mandibular segment and the movement of any segment during surgery or postsurgical stability of any other segment.
Results
At T1, the distal segment had moved forward and upward and rotated upward (all p < 0.001). The deviated proximal segment had moved upward, tilted to the opposite side, and rotated upward (all p < 0.001) and the opposite proximal segment had moved upward (p < 0.001) and tilted to the deviated side (p < 0.01). Sagittal relapse of the distal segment was mainly related to the sagittal instability of the deviated proximal segment (p = 0.001) and pitch rotation during surgery of the opposite proximal segment (p < 0.01). The roll relapse of the opposite proximal segment was mainly related to the vertical movement during surgery of the deviated proximal segment (p < 0.001) and transverse instability of the distal segment (p < 0.01).
Conclusions
Clinically significant relapse of class III asymmetry was discovered on the mandibular distal and opposite proximal segments and was mainly related to the movement of the deviated proximal segment during and after surgery.
Diversity and reproduction of raptors in urban areas in southern Chile
Authors: Muñoz-Pedreros Andrés , Norambuena Heraldo V.
Published: January 2023

Cities in general possess limited areas of original vegetation, or even artificial green areas; this results in drastic modification of faunal communities, with reductions in their original abundance and diversity. Nevertheless, some species are able to thrive in cities, including high trophic level species such as raptors. The object of this study was to characterise the diversity, abundance and reproduction of diurnal and nocturnal raptors in the urban area of a city in southern Chile. Twelve species of raptor were recorded, seven diurnal and five nocturnal. The species recorded most frequently were Coragyps atratus and Glaucidium nanum; the least frequent species were Parabuteo unicinctus and Elanus leucurus. Eighteen nesting sites were recorded of six species of diurnal and nocturnal raptors: Falco sparverius, Milvago chimango, G. nanum, Strix rufipes, Tyto alba and Athene cunicularia. This is a good sample of the diversity of raptor species which reside permanently in urban areas.
Can a glycated hair protein assay be a non-invasive indicator of blood glucose control? - Assessing the influence of sample mass and chemical hair treatments
Authors: Dhanoo Andrew S. , Cockburn Brian N
Published: January 2023

Aims: To determine if glycated protein found in scalp hair can predict blood glucose control as characterised by HbA1c. Also, to investigate cosmetic hair treatments' effect and hair sample mass's effect on the assay.
Materials and Methods: 192 participants were included in this study. Anthropometrics, medical history and about 50 strands of hair, 4 cm long, proximal to the scalp, were collected. The concentration of fructosamine in hair was determined using the Thiobarbituric Acid (TBA) method with a fructose calibration curve. The strength of the correlation between HbA1c and fructosamine for hair samples with and without hair treatments was assessed using Pearson's R.
Results: For the samples with no reported hair treatments, there was a statistically positive association between HbA1c and fructosamine when the sample mass ranged between 40mg to 120 mg. A high positive association, r(28) = 0.647, p = <0.001 was observed when hair samples greater than 70mg were used.
Conclusions: Hair glycation can be a robust, non-invasive indicator of blood glucose control in optimum settings. However, sample collection limitations, lengthy assays, and the influence of cosmetic treatments limit its usefulness as a screening tool for diabetes.

Published: January 2023

Objective: To evaluate the risk factors of patients with locally advanced cervical cancer (LACC) undergoing radical radiotherapy (with or without concurrent chemotherapy) and to assess the prognostic value of tumor volume regression (TVR) based on magnetic resonance imaging (MRI) in different risk groups.
Methods: A retrospective analysis was performed on 176 individuals diagnosed with stage IIA-IVA cervical cancer (CC) who underwent radical intensity-modulated radiotherapy in our center between January 2012 and December 2020. The tumor volume before radiotherapy (TVp) and before brachytherapy (TVmid) were evaluated based on three-dimensional MRI images, TVR = (TVp -TVmid)/TVp×100%. Kaplan-Meier curves were used to assess patient’s overall survival (OS) and progression-free survival (PFS). Prognostic factors were identified using Cox proportional hazards models.
Results: For the entire cohort, patients with TVR ≥ 94% had better 5-year OS (82.7% vs 49.8%, p<0.001) and 5-year PFS (82.5% vs 51.1%, p<0.001) compared to TVR < 94%. Patients with TVR ≥ 94% were more likely to receive concurrent chemoradiotherapy (CCRT) than those with TVR < 94% (70.1% vs 40.5%, p<0.05). Among patients undergoing CCRT, those with a TVR ≥ 94% had a better prognosis than those with a TVR < 94%. However, among patients who received RT alone, those with TVR ≥ 94% had better PFS but no statistically significant difference in OS. Likewise, among patients with CYFRA21-1 < 7.7 ng/ml, patients with TVR ≥ 94% had a better prognosis. However, TVR was not a prognostic factor in patients with CYFRA21-1 ≥ 7.7 ng/ml. Both CYFRA21-1 (OS, PFS interaction, p<0.001) and FIGO stage (PFS interaction, p=0.035) were found to significantly impact predictive effects of TVR.
Conclusion:
In LACC patients with CRYFA21-1 < 7.7 ng/ml who received CCRT, TVR was an important prognostic factor. However, in patients with CRYFA21-1 ≥7.7 ng/ml who received RT alone, the prognostic value of TVR needs to be further explored.

Exploring the value of an educational partnership within a multilingual pre-school setting
Authors:   , Maritz Anneliese
Published: January 2023

This modest research project was situated in a multilingual Early Childhood Development (ECD) setting in the Eastern Cape (EC) province of South Africa. In the context of high levels of poverty and unemployment in the EC, issues such as under-funding, the nature of the training of practitioners, translating the importance of learning through play into practice, difficulties dealing with diverse cultural practices and the use of multiple languages, all impact ECD provision. Research has shown that parental involvement and creating parent-school partnerships can assist children to progress at school. The overall objectives of this project were to explore how a team in an ECD centre might communicate more effectively with parents and how early stimulation practices in home and school might benefit the child’s development. The theoretical framework draws upon Vygotsky’s (1978) socio-cultural historical theory, Bernstein’s (1971) elaborated and restricted language codes and Bourdieu’s (1977) concepts of social reproduction. A research project in the Netherlands Thuis in School, used an education partnership approach (Iliás et al., 2019). They developed a manual that was adapted for our local context by drawing from the theories mentioned, and to counter the dominant approaches where parenting programs have often been offered from a deficit, narrow perspective. Action Research guided the interventionist approach to workshop sessions, to enable mutual capacity-building of parents and practitioners. To ensure informed consent, participants’ first languages were used. High risk factors related to photographs and videos of participating parents and minor children were successfully addressed. Pre- and post-interviews and workshop data were analysed using template analysis, within a constructivist paradigm. Findings include vignettes to introduce the contexts and parents' ideas prior to the sessions. Then, sessions are summarised as action cycles, with key participants' responses. Finally, post-session evaluations highlight the topics the parents found most meaningful; and parents’ and practitioner accounts of changes in practices. This research illustrates ways that educational partnership elements can influence practice and policy, to improve home and school environments for the benefit of children.

Published: January 2023

This study aimed to produce a computer-based test instrument for higher-order thinking skills (CBT-HOTS) on the chemical bonding materials and to determine the higher-order thinking skills of students in Class X MIA at MAN Binjai Academic Year 2021/2022. This research employed the ADDIE model of Research and Development (RD). The test instrument was created in the form of multiple-choice consisting of 30 questions measuring the cognitive domains of analyzing (C4), evaluating (C5), and creating (C6). Based on the findings, the developed instrument was declared feasible for use, considering that it had met the required content validity by expert assessments using the Aiken’s V index in the range of 0.97 to 1.00 and the reliability value of 0.93. The students' higher-order thinking skills on chemical bonding materials were included in the "high" category. It was shown from the percentages of answers to the HOTS questions in each involved domain; analyzing (C4) by 28%, evaluating (C5) by 44%, and creating (C6) by 28%. Additionally, the average score was 74.64, indicating that students' higher-order thinking skills were high.
Sustainability of rural water services in the humanitarian-development-peace nexus: a case study from Diffa, Niger
Authors: Hayes Paul , Fawcett Ben
Published: January 2023

Violence committed by non-State armed groups has displaced over 250,000 people in the Diffa region of Niger and crippled the regional economy. The humanitarian response included substantial investment in water infrastructure which has largely alleviated the immediate needs of displacement-affected populations. However, ongoing insecurity threatens the sustainability of these rural water services. A systems-thinking approach to explain the interaction between different sustainability factors for rural water services is advocated by a growing body of literature, but is almost exclusively focused on stable contexts. The applied research reported here adopted a qualitative assessment methodology to determine the impact of the insecurity in Diffa on these sustainability factors. Twenty-five respondents from government, water management structures, donors, and non-governmental organisations were interviewed between March and June 2021. The research demonstrated that insecurity in Diffa impacts negatively on all sustainability factors for rural water services and impedes access, coordination, and communication by and between relevant actors. The overlapping humanitarian and development contexts and the push to implement a triple nexus approach – which includes peace as its third element – raise dilemmas concerning the application of water tariffs, the durability of water infrastructure, and the suitability of a community-based approach to water management.
Coping with water insecurity in urban Ghana: patterns, determinants and consequences
Authors: Achore Meshack , Bisung Elijah
Published: January 2023

In Sub-Saharan Africa (SSA), rapid urbanization poses unprecedented challenges in terms of water security and associated health risks. Like most SSA countries, many Ghanaian households lack access to safely managed drinking water sources and resort to a patchwork of alternative sources for their water needs. This paper examines determinants and implications of water insecurity coping strategies in resource-constrained neighborhoods in Ghana, using a survey (n = 1192) of adult active water collectors within households in Accra and Tamale. Findings suggest that water insecure households were more likely to adopt behavioral, physical and a mix of behavioral and physical coping strategies. Households were more likely to use behavioral (OR = 5.64, p = 0.00), physical (OR = 3.18, p = 0.00) and behavioral and physical (OR = 4.20, p = 0.00) coping strategies in the dry season. Compared with the wealthy, the less wealthy (OR = 0.27, p = 0.00) were less likely to employ a mix of physical and behavioral coping strategies. Likewise, males were less likely (OR = 0.64, p = 0.03) to employ a behavioral coping strategy. The findings can help practitioners identify vulnerable groups and provide targeted interventions that seek to build or strengthen coping strategies in the short term.

Giardia spp. is an intestinal parasite responsible for worldwide disease outbreaks. Guiding researchers and practitioners to choose among current methods for microscopy detection of the infectious forms may be directly beneficial to public health and the environment. This study provides an overall comparison of brightfield (BF), fluorescence and darkfield (DF) microscopies for detecting Giardia duodenalis and Giardia muris cysts, by illustrating micrographs of such protocols applied to purified samples, as well as discussing advantages and constraints based on secondary information and collected data. BF analysis included Lugol's iodine staining. In fluorescence microscopy, samples were processed by immunofluorescence assay (IFA) with DAPI and by standalone DAPI dye. Cyst suspensions were also analysed by DF microscopy using a recently developed low-cost system. The three techniques enabled detecting Giardia spp. cysts, although they did not provide species identification by morphology. The overview of each method points out some relevant aspects to consider when selecting common optical microscopy techniques, and includes challenges and advantages regarding each of them.

Figuras estéticas e literárias da salvação do mundo: tempo, ordem, e criatividade
Authors: Reis José Eduardo
Published: January 2023

The idea of saving the world is an enthralling and compelling provocation regarding the necessity, feasibility, or futility of such an endeavour. This essay is an attempt to respond to that provocation by drawing on quantum physicist David Bohm’s concept of “implicate order,” a physical dimension underlying the world of phenomena defined by the inseparability of consciousness and matter, and on the heuristic value he confers on metaphorical thinking. It draws on the work of Anthony Gormley, Kazuaki Tanahashi, Homero, Ferreira de Castro, and Ana Luísa Amaral.
Graphene/nanotube quasi-1D structures in strong electric fields

Published: January 2023

In silico studies of the behavior of graphene/nanotube quasi-one-dimensional (1D) structures with covalent bonded graphene and nanotube in strong electric fields with a strength of 10^7-108 V/cm have been carried out. The atomic structure, band structure, electron transmission function, electrical conductivity, and regularity of the electronic structure changes in strong fields have been studied. It is found that the electron transmission function of quasi-1D structures has an intensity peak at the Fermi level in contrast to nanotubes and graphene. As a result of quantum molecular dynamics modeling, the regularities of deformation of the atomic framework and its destruction under the action of ponderomotive force have been established. We have found a critical value of the strength at which the electric field detaches the graphene from the tube. It is ~2·108 V/cm. A further increase leads to the detachment of graphene from the tube with its simultaneous destruction. Keywords: graphene/nanotube structures, electrical conductivity, ponderomotive force, strong electric fields.

Published: January 2023

Photoelectron spectroscopy was used to study the electronic structure in situ in an ultrahigh vacuum before and after the adsorption of sodium atoms on the surface of tungsten oxidized at an oxygen pressure of 1 Torr and a temperature of 950 K. The photoemission spectra from the valence band and the W 4f, O 2s, and Na 2p core states were studied under synchrotron excitation in the photon energy range 80-600 eV. It is found that a tungsten oxide film is formed containing various tungsten oxides with an oxidation state of 6+ to 4+. The deposition of a 1.1 monolayer of sodium atoms on the surface of oxidized tungsten leads to the reduction of the W6+ states to W4+ and the reaction with oxygen in the hydroxyl composition, which is reflected in the change in the spectrum of the W 4f and O 2s core states. It is shown that the cathodoluminescence spectrum is associated with the luminescence of tungsten oxide. Keywords: adsorption, sodium, tungsten oxides, photoelectron spectroscopy, cathodoluminescence.

Published: January 2023

A series of composites is synthesized on the basis of oligomeric diisocyanate with different contents of ferroelectric filler barium titanate (BaTiO3). The dielectric performances of the obtained composites are found to follow extreme dependences on the filler content with a sharp minimum of the dielectric permittivity and maximum of the dielectric loss tangent at BaTiO3 content 30 vol.%. The characterization of the composite layers by confocal microscopy revealed that the observed dependences of their dielectric properties upon the composition are determined by structural changes of the composites, including percolation, formation of a single infinite cluster and structures of matrix-island and chain types at certain critical concentrations. Keywords: composites, coatings, diisocyanate, barium titanate, dielectric permittivity, dielectric loss, electrochromatography, supercapacitors.

Grey solitons in the ultracold fermions at the full spin polarization
Authors: Andreev P. A.
Published: January 2023

A minimal coupling quantum hydrodynamic model of spin-1/2 fermions at the full spin polarization corresponding to a nonlinear Schrodinger equation is considered. The nonlinearity is primarily caused by the Fermi pressure. It provides an effective repulsion between fermions. However, there is the additional contribution of the short-range interaction appearing in the third order by the interaction radius. It leads to the modification of the pressure contribution. Solitons are considered for the infinite medium with no restriction on the amplitude of the wave. The Fermi pressure leads to the soliton in form of the area of decreased concentration. However, the center of solution corresponding to the area of minimal concentration has nonzero value of concentration. Therefore, the grey soliton is found. Soliton exist if the speed of its propagation is below the Fermi velocity. Keywords: degenerate fermions, hydrodynamics, non-linear Schrodinger equation, dark soliton, Fermi pressure.

Planar ensembles of multilayer periodic square microelements of the type [Cu(6 nm)/FeNi(100 nm)]5 were obtained by ion-plasma sputtering on glass substrates using mesh copper masks. The surface features of trace elements were analyzed using a stylus profilometer, optical and scanning electron microscopy. Static magnetic properties and features of the magnetic domain structure were studied using the magneto-optical Kerr effect. The resulting planar ensembles can be used as an integral part of the film elements of weak magnetic field detectors operating on the basis of magnetic impedance (MI) to increase the sensitivity of the MI response to an external magnetic field.

The influence of structural distortions on magnetic and ferroelectric properties is studied, possible magnetoelectric effects (linear, quadratic, inhomogeneous) in these materials are determined, and expressions for the linear magnetoelectric effect tensor are given. Macroscopic manifestations of the inhomogeneous magnetoelectric effect in multiferroic nanoelements are considered. Keywords: multiferroics, magnetoelectric effect, perovskites, symmetry.

Giant spin-valve effect in yttrium--ion garnet--aluminum structures
Authors: Scriabina O. V.  , Uspenskaya L. S.
Published: January 2023

The nature of resistive switching in structures of yttrium iron garnet-aluminum (YIG/Al) observed when the current direction is changed relative to the direction of YIG magnetization has been studied. It has been established that the effect observed when the magnetic field is rotated increases with an increase in the current passed through the structure and achieves 100 percent switching from the superconducting to the normal resistive state. The magnitude of the effect depends on geometric factors, namely, on the ratio of the lateral dimensions of the YIG plates. Modeling the configuration of the magnetostatic stray fields showed that the effect is partially determined by these fields. It has been established that the inversion of the current flowing through the structures also leads to a variation in their resistance. The effect reaches 20% near the temperature of superconducting transition. Keywords: magnetic dielectrics, superconductor, proximity effects, spin-orbit coupling, Zeeman field, spin-valve.

It is shown that the power reflection coefficient can vary from -20 to -3 dB depending on the operating point. An experimental method for determining the impedance of the supply line of the SIS-mixer is proposed and tested.

Exchange spring-like inhomogeneous states in a ferromagnetic wire with current
Authors: Tikhomirov O.A.
Published: January 2023

Transverse structure of magnetization in a ferromagnetic film induced by magnetic field of electric current has been analyzed. Two steps of arising exchange spring evolution are shown. The first one (weak current) is gradual twisting of magnetization aside from the wire axis. Above some critical current the transient area is compressed and localized near the middle plane. In presence of additional conductive layer the transient structure becomes asymmetric resulting to non-zero lateral component of the net magnetization. It is shown also that the mentioned asymmetry can provide additional displacement of domain walls after the electric current pulses. Keywords: spintronics, domain wall dynamics, exchange spring, ferromagnet.

The effect of surface functionalization with citric acid on the properties of magnetic nanoparticles (MNPs) ZnxFe3-xO4 (x=0; 0.25; 0.5; 0.75; 1.0) synthesized by the hydrothermal method was studied. To study the properties of MNPs, X-ray diffractometry (XRD) and energy dispersive X-ray spectroscopy (EDS) were used. The magnetic properties of the samples and the phase state of MNPs were studied using a physical property measurement system (PPMS) and Mossbauer spectroscopy (MS). It has been established that the sizes of crystallites and the crystal lattice parameter of ZnxFe3-xO4 MNPs change with increasing Zn2+ concentration. The low values of the coercive force and the presence of a doublet on the MS indicate the presence of both ferrimagnetic and superparamagnetic components.

Superstructural ordering degree in nanosized strontium ferromolybdate according to ferromagnetic resonance data
Authors: Demyanov S.E.  , Petrov A.V.
Published: January 2023

Powders of strontium ferromolybdate (Sr2FeMoO6-delta) with various degrees of superstructural ordering of iron and molybdenum cations (P=67, 81, 89%) were studied by the ferromagnetic resonance method. These investigations have been carried out taking into account the available information on the structural, magnetic and resistive characteristics of the samples under study. As a result of the analysis of the ferromagnetic resonance spectra, it was concluded that the amplitude of the corresponding signals strongly depends on the magnitude of the superstructural ordering, increasing with its growth. The presence of maxima in the ferromagnetic resonance spectrum in the temperature range 350-370 K, which shift slightly to low temperatures with increasing P, confirms the existence of ferrimagnetic and antiferromagnetic states competing with each other in the region close to the Curie temperature. Keywords: ferromagnetic resonance, strontium ferromolybdate, superstructural ordering of cations, dynamic light scattering, submicron particles.
