Neoliberalismo e políticas de educação especial
Authors: Borges Kamylla Pereira
Published: March 2022

As políticas de educação inclusiva são marcadas por embates entre diferentes projetos de sociedade. Este artigo tem como objetivo geral compreender a relação entre os princípios neoliberais e as políticas de educação especial inclusiva dos Governos do Partido dos Trabalhadores (PT): Lula (2003-2010) e Dilma Rousseff (2011-2016). Trata-se de um estudo de natureza qualitativa, do tipo exploratório, descritivo e analítico. A coleta de dados se deu por meio de uma pesquisa bibliográfica e da análise documental. Após a análise, concluímos que tanto os recursos para financiamento quanto as matrículas de alunos com necessidades educacionais específicas aumentaram, mas a lógica neoliberal se manteve. Isso pode ser visto na manutenção do financiamento público às instituições assistenciais privadas, na terceirização do Atendimento Educacional Especializado (AEE) via parcerias público-privadas e na definição da educação como um serviço em vez de um direito.

Recent developments in understanding brain aging: sex differences, mechanisms, and implications in diseases
Authors: Yang Jing , Qu Jing , Ma Huan
Published: March 2022

Exemplified by the disproportionate cases of Alzheimer’s disease among women, many diseases show considerable sexual disparity in the aging process. Given that such a sex bias varies significantly in different neurological conditions, considering sex differences is necessary for the diagnosis as well as the treatment of neurological disorders. However, currently, relatively few studies have specifically focused on sex differences in brain aging or the general aging process, which has prevented the development of precision medicine for these sex-different diseases. Here, we summarize age-related disparities relating to cognitive function and dysfunction for males and females from human cross-sectional and longitudinal studies. By discussing potential anatomical and physiological bases underlying such differences, we highlight the importance of sex for aging studies in this review, which may hopefully shed light on understanding the precise causes of different brain diseases.

Published: March 2022

It is of vital importance to boost the intrinsic activity and augment the active sites of expensive and scarce platinum-based catalysts for advancing a variety of electrochemical energy applications. We herein report a mild electrochemical bottom-up approach to deposit ultrafine, but stable, Pt8Ag4 alloy clusters on carbon nanotubes (CNTs) by elaborately designing bimetallic organic cluster precursors with four silver and eight platinum atoms coordinated with µ,σ-bridged ethynylpyridine ligands, i.e., [Ag4(C24H16N4Pt)8(BF4)4]. The Pt8Ag4 cluster/CNT hybrids present impressively high platinum mass activity that is threefold that of commercial Pt/C toward the hydrogen evolution reaction, as a result of the cooperative contributions from the Ag atoms that enhance the intrinsic activity and the CNT supports that increase the activity sites. The present work affords an attractive avenue for engineering and stabilizing Pt-based nanoclusters at the atomic level and represents a promising strategy for the development of high-efficiency and durable electrocatalysts.

Published: March 2022

The scarcity of lithium resources and the unsafety of organic electrolytes limit the further application of lithium-ion batteries (LIBs) in electric vehicles and grid-scale energy storage. Aqueous zinc-ion batteries (AZIBs) are potential complements for LIBs for large-scale grid energy storage because of their abundant resources, environmental friendliness, intrinsic safety and low cost. However, current AZIBs are mainly based on intercalation-type cathodes and their energy densities are not competitive with LIBs. Fortunately, conversion-type cathodes, with higher specific capacity and lower price, endow AZIBs with excellent potential for practical applications. In this review, the mechanism of energy storage and the progress in developing AZIBs based on conversion-type cathodes are summarized. Perspectives on critical scientific issues and the potential developmental directions of AZIBs are also proposed.

Published: March 2022

We investigated the early effects of low dose sacubitril/valsartan (S/V) on cardiac reverse remodeling (CRR). Methods: In 37 patients (45- excluded 8pts,mean age 64.5±17.5 years, five females), 24/26 mg S/V BID was started, and the second evaluation was performed after month. Results: Following CRR parameters improved: LVEDD (-∆2,9±2.6 mm; Student’s t-test: p =0.0098), LVESD (-∆2,4±2.5 mm; Student’s t-test: p=0.0092), LVEDV (-∆14.6±33.1 mL; Wilcoxon test: p = 0.0412), LVESV (-∆13.4±30.6 mL; Wilcoxon test: p =0.0442), LAVI (-∆8.7±37.7 mL/m2; Wilcoxon test: p = 0.0012), and EROA (-∆0.09±0.01 cm2; Student’s t-test: p = 0.0318). In opposite to LVEF, global longitudinal strain (GLS) changed from -6.6% to -7.9% (absolute improvement of 16%, Wilcoxon test: p=0.0013). Other parameters improving: 6-MWT (+∆65.4±75.8 m; Wilcoxon test: p = 0.0013) and the quality of life (MLHFQ 22 vs 16 scores; Student’s t-test: p= 0.0098), NT-pro BNP (-∆1203.1±3121.4 pg/mL; Student’s t-test: p = 0.0348) and troponin T (-∆ 4.7±9.4 pg/mL, Wilcoxon test: p = 0.0041). Correlation between GLS and LVESV (Pearson's correlation coefficient: r = -0,4596, p = 0.0239) was found. ROC curve analysis showed that in the group with severe systolic dysfunction (GLS< -8%) clinical improvement (6MWT: AUC = 0.692, p = 0.0383) and CRR (MRvol: AUC = 0.736, p = 0.0062; LAVI: AUC = 0.710, p = 0.0414) are more likely to occur. Conclusions: Low-dose (24/26 mg BID) S/V therapy initiates CRR. S/V should be started in patients with less impaired LV systolic function (GLS < -8%) because CRR and clinical improvement are more likely to develop.

Authors: Khotimah Bain Khusnul
Published: March 2022

Maize is one kind of commodity consumption in domestic as well as export that has high economic value. However, the low productivity is caused by the main factor, namely the decreased level of soil fertility, so that it has the same effect on crop yields. These problems require the application of technology with the K-Nearest Neighbor (KNN) method. The method of study is based on 17 signs of nutrient deficiencies with Minkowski distance calculation process, calculation of deficiency of soil nutrients based on the value of K determined. The test results of the research use K = 75 to get an accuracy of 92.40. Comparative analysis of the K-nearest neighbor (K-NN) and NB methods by looking for the closeness between the criteria for new cases and old case criteria based on the criteria for the closest cases. The results showed that the K-Nearest Neighbor (K-NN) Algorithm had a better accuracy value than NB.
Frequency domain analysis of MFCC feature extraction in children’s speech recognition system
Authors: Hidayat Risanuri
Published: March 2022

Abstract —The research on speech recognition systems currently focuses on the analysis of robust speech recognition systems. When the speech signals are combined with noise, the recognition system becomes distracted, struggling to identify the speech sounds. Therefore, the development of a robust speech recognition system continues to be carried out. The principle of a robust speech recognition system is to eliminate noise from the speech signals and restore the original information signals. In this paper, researchers conducted a frequency domain analysis on one stage of the Mel Frequency Cepstral Coefficients (MFCC) process, the Fast Fourier Transform (FFT), in children's speech recognition system. The FTT analysis in the feature extraction process determined the effect of frequency value characteristics utilized in the FFT output on the noise disruption. The analysis method was designed into three scenarios based on the value of the employed FFT points. The differences between scenarios were based on the number of shared FFT points. All FFT points were divided into four, three, and two parts in the first, second, and third scenarios, respectively. This study utilized children's speech data from the isolated TIDIGIT English digit corpus. As comparative data, the noise was added manually to simulate real-world conditions. The results showed that using a particular frequency portion following the scenario designed on MFCC affected the recognition system performance, which was relatively significant on the noisy speech data. The designed method in the scenario 3 (C1) version generated the highest accuracy, exceeded the accuracy of the conventional MFCC method. The average accuracy in the scenario 3 (C1) method increased by 1% more than all the tested noise types. Using various noise intensity values (SNR), the testing process indicates that scenario 3 (C1) generates a higher accuracy than conventional MFCC in all tested SNR values. It proves that the selection of specific frequency utilized in MFCC feature extraction significantly affects the recognition accuracy in a noisy speech.

We live in a bizarre world that is constantly changing. While thousands fall into a country demarcated below poverty lines, the world's top ten wealthiest men appeared to have more than doubled their fortunes during the epidemic. 'Davos Man: How the Billionaires Destroyed the World,' a book written by New York Times reporter Peter Goodman, explored how the ultra-rich are responsible for things like climate change, violence, and the collapse of democracy. Social workers seem to go along with fixing the society and reach the last impoverished man on the planet, unmindful of what appears to happen to resources.   The following is a report on the topics that were discussed at a meeting of social workers from around the world on 15 March 2022, which the Brisbane Institute of Strengths-Based Practice organised. Journal Space and Culture, India was also a part of this endeavour. There were nearly one hundred social workers attending the conference and a few thousand through other social media outlets.
3D Printed Engineered, Strain-Hardening Geopolymer Composite (EGC/SHGC) as Permanent Formwork for Concrete Beam Construction
Authors: Bong Shin Hau , Nematollahi Behzad , Mechtcherine Viktor , Li Victor C. , Khayat Kamal H.
Published: March 2022

The extrusion-based 3D concrete printing (3DCP) technology allows the fabrication of permanent formwork with intricate shapes, into which fresh concrete is cast to build structural members with complex geometry. This significantly enhances the geometric freedom of concrete structures without the use of expensive temporary formwork. In addition, with proper material choice for the permanent formwork, the load-bearing capacity and durability of the resulting structure can be improved. This paper investigates 3DCP of permanent formwork for reinforced concrete (RC) beam construction. A 3D-printable engineered geopolymer composite (3DP-EGC, or strain-hardening geopolymer composite, 3DP-SHGC) recently developed by the authors was used for fabrication of the permanent formwork. The 3DP-EGC exhibits strain-hardening behaviour under direct tension. Two different printing patterns were used for the soffit of the permanent formwork to investigate the effect of this parameter on the flexural performance of RC beams. A conventionally mould-cast RC beam was also prepared as the control beam for comparison purposes. The results showed that the RC beams constructed using the 3DP-EGC permanent formwork exhibited superior flexural performance to the control beam. Such beams yielded significantly higher cracking load (up to 43%), deflection at ultimate load (up to 60%), ductility index (50%) and absorbed energy (up to 107%) than those of the control beam. The ultimate load was comparable with or slightly higher than that of the control beam. Furthermore, the printing pattern at the soffit of the permanent formwork was found to have a significant influence on the flexural performance of the RC beams.

Published: March 2022

Head and neck cancer is the sixth most frequent cancer type. Drug resistance and toxicity are common challenges of the existing therapies, making the development of reliable preclinical models essential for the study of the involved molecular mechanisms as well as for eventual intervention approaches that improve the clinical outcome. Preclinical models of head and neck squamous cell carcinoma have been traditionally based in cell lines and murine models. In this review, we will go over the most frequently used preclinical models, from immortalized-cell and primary tumour cultures in monolayer or 3D, to the currently available animal models. We will scrutinize their efficiency in mimicking the molecular and cellular complexity of head and neck squamous cell carcinoma. Finally, the challenges and opportunities of other envisaged putative approaches, as well as the potential of the preclinical models to further develop customized therapies will be discussed.

Published: March 2022

Advanced manufacturing techniques, aimed at implants with high dependability, flexibility, and low manufacturing costs, are crucial in meeting the growing demand for high-quality products like biomedical implants. Incremental sheet forming is a promising flexible manufacturing approach for rapidly prototyping sheet metal components using low-cost tools. Titanium and its alloys are used to shape most biomedical implants because of its superior mechanical qualities, biocompatibility, low weight, and great structural strength. The poor formability of titanium sheets at room temperature, however, limits their widespread use. The goal of this research is to show that gradual sheet formation of a titanium biomedical implant is possible. The possibility of creative and cost-effective concepts for the manufacturing of such complicated shapes with significant wall angles is explored in this study. A numerical simulation based on finite element modeling as well as a design process tailored to metal forming is used to complete the development. The mean of uniaxial tensile tests with a constant strain rate was used to study the flow behavior of the studied material. To forecast the crack, the obtained flow behavior was modeled using the behavior model and failure model.

Probing Nuclear Dipole Moments and Magnetic Shielding Constants Through 3-Helium NMR Spectroscopy
Authors: Makulski Włodzimierz
Published: March 2022

Multinuclear NMR studies of the gaseous mixtures that involve volatile compounds and 3He atoms are featured in this review. Precise analyses of the 3He and other nuclei resonance frequencies show linear dependences on the gas density. Extrapolation of the gas phase results to the zero-pressure limit gives ν0(3He) and ν0(nX) resonance frequencies of nuclei in a single 3-helium atom and nuclei in molecules at a given temperature. The NMR frequency comparison method provides an approach for determining different nuclear magnetic moments. Application of quantum chemical shielding calculations which include a more complete and careful theoretical treatment allows the shielding of isolated molecules to be achieved with great accuracy and precision. They are used for evaluation of nuclear moments without shielding impact on bare nuclei: 10/11B, 13C, 14N, 17O, 19F, 21Ne, 29Si, 31P, 33S, 35/37Cl, 33S , 83Kr, 129/131Xe, and 183W. On the other hand, new results of nuclear moments were used for reevaluation of absolute nuclear magnetic shielding in molecules under study. Additionally, 3He gas in water solutions of lithium and sodium salts was used for measurements of 6/7Li and 23Na magnetic moments and reevaluation of shielding parameters of Li+ and Na+ water solvated cations. In this paper, guest 3He atoms that play a role in probing the electron density in many host macromolecules are presented as well.
Collatz Conjecture: An Order Machine
Authors: Williams Michael
Published: March 2022

Collatz conjecture (3n+1 problem) is an application of Cantor's isomorphism theorem (Cantor-Bernstein) under recursion. The set of 3n+1 for all odd positive integers n, is an order isomorphism for (odd X, 3X+1). The other (odd X, 3X+1) linear order has been discovered as a bijective order-embedding, with values congruent to powers of four. This is demonstrated using a binomial series as a set rule, then showing the isomorphic structure, mapping, and cardinality of those sets. Collatz conjecture is representative of an order machine for congruence to powers of two. If an initial value is not congruent to a power of two, then the iterative program operates the (odd X, 3X+1) order isomorphism until an embedded value is attained. Since this value is a power of four, repeated division by two tends the sequence to one. Because this same process occurs, regardless of the initial choice for a positive integer, Collatz conjecture is true.

Ketersediaan air di bumi terdiri dari 94 % air asin dan 6 % air tawar. Dari 6 % air tawar tersebut, 95 % merupakan air tanah, 3,5 % air permukaan dan 1,5 % kelembaban tanah. Potensi air tanah di Indonesia sebesar 712 milyar m³/tahun yang tersedia pada 421 Cekungan Air Tanah (CAT). Cekungan air tanah adalah suatu wilayah yang dibatasi oleh batas hidrogeologis, tempat semua kejadian hidrogeologis, seperti pengimbuhan, pengaliran, dan pelepasan air tanah berlangsung. Penentuan CAT bukan didasarkan pada batas administrasi melainkan pada batas hidrogeologis, oleh karena itu banyak CAT yang keberadaannya melintasi dua wilayah administrasi atau lebih. Kabupaten Demak memiliki 2 (dua) daerah cekungan air tanah lintas kabupaten/kota yaitu CAT Semarang-Demak dan CAT Kudus, di mana potensi ketersediaan air tanahnya mencapai ± 1,249 juta m3/tahun. Pemanfaatan air tanah di Kab. Demak mencapai 1,402 m3/dtk atau 44.213.472 m3/tahun. Berdasarkan analisa neraca air tanah, kondisi eksisting dan proyeksi 25 tahun mendatang masih mencukupi (surplus) dengan rata-rata 1.176 juta m3, akan tetapi hal ini harus diimbangi dengan pengelolaan air tanah secara terpadu. Pengelolaan dalam pemanfaatan air tanah meliputi kegiatan perencanaan, pelaksanaan, pemantuan, pengevaluasian penyelenggaraan konservasi air tanah, pendayagunaan air tanah, pengendalian daya rusak air tanah berbasis cekungan air tanah.

Indonesia dengan kekayaan jenis material bahan konstruksi merupakan salah satu faktor pendukung untuk melakukan studi-studi akan potensi material tersebut sebagai pengganti semen. Penelitian ini dilakukan untuk mengetahui pengaruh variasi perbandingan massa aktivator Na2SiO3:NaOH sebesar 0 (tanpa alkali), 1:2, 2:2, 3:2 dengan metakaolin 17,5% terhadap nilai kuat kejut dan keuletan beton mutu tinggi memadat mandiri (HSSCC). Metode yang digunakan pada penelitian ini adalah metode eksperimental. Digunakan benda uji beton silinder diameter 15 cm dengan tinggi 6 cm untuk pengujian kuat kejut dan beton balok dengan ukuran 40 cm x 10 cm x 10 cm untuk pengujian keuletan. Pengujian kuat kejut dilakukan dengan metode drop weight test oleh beban kejut, kemudian dilakukan pencatatan jumlah pukulan sampai benda uji runtuh dan perhitungan energi serapan setiap variasi beton. Pengujian keuletan dilakukan dengan metode pembebanan bertambah pada satu titik pembebanan menggunakan mesin UTM. Nilai keuletan merupakan luasan yang dihasilkan dari regresi hubungan beban dan lendutan yang dapat diterima benda uji sebelum retak. Pengujian dilakukan pada saat benda uji memiliki umur 28 hari. Hasil penelitian menunjukkan bahwa beton dengan perbandingan massa aktivator Na2SiO3:NaOH sebesar 2:2 mempunyai kuat kejut dan keuletan paling tinggi, berturut-turut dengan nilai 33207,3 Joule dan 1,3026 kNmm. Untuk itu penggunaan aktivator Na2SiO3:NaOH yang disarankan adalah 2/2 atau sebanding.

Of the four atoll countries in the world, the Maldives has the lowest average elevation. Therefore, it is likely to be the first country to lose its land when the sea level rises due to climate change. As a countermeasure to sea level rise, the government of the Maldives is constructing an artificial island called Hulhumalé by raising an atoll adjacent to the capital city of Malé. Other atoll countries may employ the same method to adapt to the anticipated sea level rise. There is a concern that people who are forced to relocate to the artificial island will be affected in various ways. Therefore, the purpose of this study was to identify measures to reduce the potential impacts of migration to artificial islands. This study aimed to identify factors that will work effectively to satisfy migrants from outside the Malé region to Hulhumalé. At this stage, sea level rise is not a motivating factor for migration to Hulhumalé. For the time being, enhancing high-income employment and high-level education in Hulhumalé, which are the main motivations for migration, will help sustain voluntary migration. Over the past two decades, rapid economic growth has changed the desire of Maldivians. Hulhumalé is attracting people with its new urban environment and employment opportunities. A small-scale questionnaire survey on the satisfaction level of post-migration life was conducted among the residents of Hulhumalé and the results showed that those who changed their jobs before and after migration were less satisfied with their migration than those who did not. In Hulhumalé, smart cities are being developed and new types of employment are being created. In order to facilitate the smooth migration of residents from remote islands, policies that focus on occupational changes before and after migration are needed, such as public job placement programs that enable migrants to find the same jobs that they had before migration, and job training programs that prepare them for career changes and enable them to adapt smoothly to new jobs. At present, mental health issues among migrants are not a major problem. Strengthening people-to-people networks through the use of information technology (IT) will contribute to smooth migration and resettlement.

The masonry of the Terme di Elagabalo at the Palatine hill (Rome). Survey, analysis and quantification of a roman empire architecture
Authors: Fornaciari Lorenzo , Brienza Emanuele
Published: March 2022

The NE slopes of the Palatine and the Colosseum valley area have been the place of a long archaeological research; here the continuous urban development produced an overlap of architectural complexes distributed over time. The huge amount of archaeological documentation produced during research is managed by an intra-site GIS. For ancient walls analysis we have introduced the use of image-based-modelling photogrammetry in order to create a very detailed 3D documentation, marked by an increasing and progressive high-level-autopsy, linked to a DBMS dedicated to ancient structural features. In this procedure we also decided to compare two different approaches to check results of both: one based on taking brick measures directly by hand, the other taking same measures on photogrammetric elaborations by GIS. Through this methodology, counting measures and dimensional aspect of wall facades features, we can evaluate specific aspects of the ancient construction yards for each period; we can also refine the chronological sequences of the architectures and verify the contextual relationships of the surrounding buildings in order to formulate wide-ranging reconstructive hypotheses.
Operational methodology for the reconstruction of Baroque Ephemeral apparatuses: the case study of the funeral apparatus for Cardinal Mazarin in Rome
Authors: Antolini Margherita
Published: March 2022

This paper aims to develop a methodology of study of Ephemeral artefacts that takes into consideration all the different aspects of the specific art form that is Ephemeral Baroque Architecture. Through the study of the social and artistic characteristics of this art form, the analysis of a wide range of case studies will help defining some common and recurring features, especially regarding available data (engravings, paintings, manuscripts, etc.) The main goal of the research will be to outline a methodology of approach to the single cases based on reconstruction from text and graphic data, with special attention reserved to the relationship between the ephemeral apparatus and the surrounding urban space. The effectiveness of the methodology is tested through the application to the case study of the funeral apparatus for Cardinal Mazarin in Rome (1661).

Colorimetric evaluation was applied on archaeological pottery from the ancient port city of Adulis in the Red Sea coast of Eritrea. Pottery samples belong to the Ayla-Aksum typology, Late Roman Amphora 1 and dolia classes, which had never been analyzed by means of this approach. The survey consisted of colorimetric measurements from different parts of the ceramic bodies, to comprehend how these data could be related to the overall fabric classification. Differences in the colorimetric parameters provided helpful information on both technological manufacturing processes and fabric classification. Subtle variations in the colour coordinates were detected and aptly interpreted, so as to ascribe the related differences. Such an approach proved that the information provided by colour measurements can be partially correlated to observations from stereomicroscopy and optical microscopy, allowing a more in-depth description of the fabrics in the study of archaeological pottery.

The circumstances and factors which determine the volcanic explosive ejection are unknown, and currently, there is no effective way to determine the end of a volcanic explosive ejection. At present, the end of an eruption is determined by either generalized standards or the measurement which is unique to the volcano. We investigate the use of controlled machine learning techniques such as Support Vector Machine (SVM), Random Forest (RF), Logistic Regression (LR), and Gaussian Process Classifiers (GPC), and create a decisiveness index D to assess the uniformity of the groups provided by these machine learning models. We analyzed the measured end-date obtained by seismic information categorization is two to four months later than the end-dates determined by the earliest instance of visible eruption for both volcanic systems. Likewise, the measurement systems, measurement technology becomes key elements in the seismic data analysis. The findings are consistent across models and correspond to previous, broad definitions of ejection. Obtained classifications demonstrate a more significant relationship between eruptive movement and visual activity than information base records of ejection start and completion timings. Our research has presented a new measurement-based categorization technique for studying volcanic eruptions, which provides a reliable tool for determining whether or not an emission has stopped without the need for visual confirmation.
