Published: October 2021

Introdução: O número da população carcerária brasileira cresce a cada dia e junto a ela, cresce também a complexidade das questões de saúde e segurança dessa população. Fatores como, a falta de higiene, a singular circulação de ar, superlotação, o uso de drogas injetáveis e as práticas sexuais, estão entre os principais contribuintes para o aumento da transmissão de doenças infectocontagiosas dentro das prisões. Objetivo: Dito isso, o presente estudo teve como objetivo analisar como se dá a propagação de doenças infectocontagiosas na população carcerária e sua prevalência. Materiais e métodos: A busca do seguinte estudo foi realizada por meio de pesquisa bibliográfica e leitura crítica, através das fontes: PubMed, Google Acadêmico, NCBI publicados entre os anos de 2014 até o presente momento. Resultados: A população carcerária é extremamente suscetível a diversos tipos de doenças infecciosas, dentre elas as mais comuns são HIV, sífilis, hepatite e tuberculose. Tais patologias estão diretamente ligadas à superlotação dos presídios, onde a alta densidade espacial das celas e as condições precárias das instalações acarretam na propagação de infecções pelo ar, também, a falta de itens básicos de higiene como preservativos para uso sexual, levam a propagação de infecções sexualmente transmissíveis. Ademais, é notável que a incidência das doenças infectocontagiosas é comum em todos os âmbitos sociais, no entanto, em populações privadas de liberdade a prevalência das mesmas é mais comum, onde é possível notar que essa prevalência possui uma média de cerca de 10% a mais que na população geral, além disso, essa população enfrenta uma maior dificuldade no tratamento, resultado da falta de diagnóstico precoce. A fim de diminuir a disseminação dessas infecções na população carcerária, é necessário que haja a implementação de uma triagem preventiva que realize diagnósticos prévios, diminuindo a propagação dessas doenças infectocontagiosas nos presídios. Conclusão: Em suma, pode-se concluir que diversas doenças infectocontagiosas têm sua prevalência em população carcerária, devido às condições precárias que lhes são proporcionadas e a falta de itens básicos de higiene. Portanto, é necessário que haja incentivo a meios de prevenção e de tratamento para amenizar os inúmeros efeitos negativos que tais doenças causam.

Introdução: As infecções respiratórias são transmitidas de hospedeiro para hospedeiros e ocorrem através de fluidos tanto gasosos como líquidos, que emitem patógenos que infectam seu novo hospedeiro. Os equipamentos de proteção individual, atuam como uma barreira física que impede a entrada de patógenos infecciosos, reduzindo a probabilidade de a doença prejudicar o organismo. Objetivo: Dito isso, este estudo teve como objetivo analisar a utilização dos equipamentos de proteção individual na redução da transmissão de doenças infecto respiratórias. Material e métodos: A busca do presente estudo teve sua realização através de pesquisa bibliográfica e leitura crítica, com a utilização das fontes: PubMed e Google Acadêmico publicados entre os anos de 2018 até o presente momento. Resultados: As doenças infecto respiratórias circulam em meio a sociedade há muito tempo, no entanto, durante o ano de 2020 devido a pandemia causada pelo corona vírus, síndromes respiratórias ganharam enfoque devido à alta taxa de transmissão em todo globo terrestre. A fim de diminuir a contaminação, determinou-se como necessário o uso diário de equipamentos de proteção individual, com a intenção de diminuir a disseminação das infecções respiratórias em circulação. A máscara mostrou-se um item eficaz ao evitar o contágio viral. Entretanto, estudos realizados recentemente demonstram que mesmo com a utilização correta da máscara, elas não bloqueiam completamente os fluídos infecciosos virais, trazendo à tona discussões sobre a sua eficácia. As máscaras de algodão, apresentaram uma redução de 20% a 40% de média na absorção do vírus comparado com a não utilização da máscara, já a N95 apresentou uma redução de aproximadamente 80% a 90%, até mesmo em cargas virais elevadas. Conclusão: Em suma, pode-se concluir que o uso de equipamentos de proteção individual contribui de forma significativa para evitar a propagação de doenças infecto respiratórias pelo ar, apesar dos equipamentos mais utilizados não possuírem proteção 100% eficaz, até as simples máscaras de algodão são capazes de reter carga viral. Logo, é necessário que o uso destes equipamentos não seja dispensado, pois contribuem para a diminuição gradativa da disseminação de doenças infeciosas pelo ar.

Authors: Cruz Mariana Ferancini De La , Souza Amanda Onofre De
Published: October 2021

Introdução: Conhecida popularmente como barriga d’ agua, a esquistossomose mansônica é uma doença infectocontagiosa parasitaria causada pelo Schistosoma mansoni que apresenta como hospedeiro intermediário caramujos do gênero Biomphalaria e como hospedeiro definitivo o ser humano. A infecção por esquistossomose acomete em geral indivíduos de menor poder aquisitivo, que moram em comunidades carentes sem saneamento básico, agua potável e sem infraestrutura. No Brasil é considerado um problema de saúde pública, sendo a região nordeste a obter a maior taxa de prevalência em todo País e encontrado em regiões tropicais e subtropicais do mundo. Objetivos: O objetivo deste estudo busca realizar um estudo avaliativo epidemiológico a partir de casos notificados da enfermidade na população de algumas localidades, trazer uma visão geral da etiologia e da patogênese da esquistossomose mansônica, seus aspectos patológicos, determinantes de maior importância para seu desenvolvimento e manifestações clínicas. Material e métodos: Para tal, foi realizada uma pesquisa bibliográfica, utilizando dados bases Scielo (Scientific Eletronic Library Online) e Pubmed (U. S. National Library of Medicine), assim como artigos científicos e livros-textos referente ao tema abordado. Resultados: 1,5 milhão de pessoas vivem em áreas com risco de contrair esquistossomose, de acordo com dados do Ministério da Saúde, o Brasil está em situação intermediária entre os 78 países em que a doença permanece endêmica e mostra mais de 60% da população sem acesso a esgotamento sanitário. As áreas endêmicas e focais abrangem 19 Unidades Federadas e compreendem os Estados de Alagoas, Bahia, Pernambuco, Rio Grande do Norte (faixa litorânea), Paraíba, Sergipe, Espírito Santo e Minas Gerais (predominantemente no Norte e Nordeste do Estado). Conclusão: Diante do exposto, a esquistossomose, atualmente, ainda é um sério problema de saúde pública devido a milhões de pessoas no Brasil contraírem a doença. Com isso, a utilização de ações educativas parte do pressuposto que quanto maior for o conhecimento sobre a doença, maior poderá ser a adesão ao tratamento e menores serão os índices de reinfecção e evolução.

Published: October 2021

Introdução: Diante dos antigos conhecimentos sobre helioterapia, no século XX, a fototerapia, que consiste na exposição de tecido cutâneo à radiação ultravioleta, findou-se como uma alternativa viável para o tratamento de patologias cutâneas, como no tratamento de doenças fúngicas e bacterianas. Ademais, a fisiopatologia do vírus HIV presume, em muitos casos, a manifestação de prurido cujo pode estar associado a algumas dermatoses. Destarte, observa-se a fototerapia, com UVB e PUVA, como uma técnica válida para pacientes portadores de HIV com expressão de prurido, já que melhora a manifestação do sistema imunológico bem como contém sintomas. Objetivo: Nesse contexto, este estudo buscou correlacionar a fototerapia (com UVB e PUVA) como um tratamento eficiente para pacientes com HIV diante dos quadros de prurido e dermatoses relativos à essa patologia. Material e métodos: Para tal, foi utilizada uma pesquisa bibliográfica, através de ferramentas on-line de busca de artigos científicos na língua portuguesa, como Scientific Eletronic Library Online (Scielo), Anais de Dermatologia, PubMed e Online Library no intervalo de 2006 a 2021. Resultado: Portanto, através dos estudos, foi constatada a eficiência do uso da fototerapia PUVA e UVB, em pacientes de HIV, promovendo alívio de prurido, englobando elevação de nível sérico de IgE, degranulação de basófilos e mastócitos, aumento da substância P (neuromodulador) em nervos periféricos afetados pelo HIV e diminuição da barreira da epiderme. Outrossim, vale ressaltar que raios UVB promovem apoptose de queratinócitos e linfócitos T por interrupção do ciclo celular; convertem ácido trans urocânico em ácido cisurocânico reduzindo a quantidade e efetividade de células apresentadoras de antígenos; reprimem a totalidade de células natural killer; e outros. Conclusão: Consequentemente, observou-se que o uso da radiação ultravioleta com PUVA e UVB é um aliado para tratar o prurido em enfermos portadores de HIV, tendo em vista as manifestações positivas no sistema imunológico. Ainda, salienta-se que esse tratamento deve ser especializado para cada quadro clínico quanto ao uso dos tipos de radiação, comprimento de onda e sessões, visando resultados mais seguros e eficazes.
A new archival hub at Wits University
Authors: Rey Matthieu
Published: October 2021

For some years, the archives in South Africa have faced a series of unprecedented challenges that threaten the high quality of the documentation and the functioning of the centers that maintain them. The crises facing the State Archives reflect problems in the state more generally including inadequate strategic investment and lack of training, which jeopardise the potential renewal of archivists. At the same time, the wide array of political activities and social movements, the dynamics of civil society organizations and activism require more than ever to curate documentation and expand the archives’ capacities. To answer this paradox, a team working in two independent archives and a research center at Wits University is experimenting with a new “hub” to constitute an important center of independent archives in South Africa. Noor Nieftagodien, director of the Wits History Workshop - the research center that has played a role in the creation of the hub - and a member of the board of the South African Historical Archives, sheds light on the new enterprise.

Today, ATMs (automated teller machines) are used in a variety of ways, including: you can withdraw cash, transfer cash, check your balance, get an account summary, and more. The main component here is security, to maintain the security we prefer cryptography and biometrics. Cryptography is a state- of-the-art technique for increasing security. Using cryptography and biometrics together creates a bio cryptographic system. Since the private key is an important component of encryption, here one is the main task to secure the private [1] key. To overcome this issue, we use a biometric fingerprint image. However, biometrics cannot protect anyone’s fingerprint template because of the many suspected attacks. Therefore, we use a fuzzy vault system that combines cryptography [2] and biometrics [4] to ensure that only authorized users can use their passwords and PINs with the legal data.

This research paper reports that in-cylinder flow formation in a combustion engine has a major influence on the combustion, emission and performance characteristics. Air and fuel enters the combustion chamber of an engine throughout the intake manifold with high velocity. So, it introduces a helical roller in the path of inlet stream of mixture. It achieved the swirl by using a component that could be easily integrated into any existing engines at low engine speed. The performance of the engine increases and completes the combustion, leads to reduced emissions and small change in volumetric efficiency. It is also proved that increased swirl movement introduces helical roller that helps the flame spread which used into constant heat transfer rate. This suggests to a new combustion technique that should be developed to yield improved primary combustion processes in-side the engine with significantly reduced exhaust gas emissions.

Agriculture is both affected by climate change but also contributes to it. As a sector, agriculture must therefore both adapt to changes and offers options for mitigation ie reducing greenhouse gas emissions and store carbon. The objective of the study is to explore the optimum level of plant nutrient for sustaining the desired crop productivity in hybrid cotton through optimization of benefit from all possible resources of plant nutrients in an integrated manner and to mitigate the green house gas emission through the adoption of Integrated Plant Nutrition System. The experiment was carried out in three locations with different soil fertility status with special emphasis to nitrogen levels in the soils. The fertilizer doses were fixed based on the soil test values and fertility grouping / indexing by International soil fertility evaluation and improvement programme. As part of organics, FYM was applied at two different levels, and the fertilizers were reduced accordingly. The results proved that application of organic manure @ 12.5 t ha-1 along with the recommended doses of nutrients proved superior in seed cotton production as well reduced nitrous oxide emissions.

NiS/ZnS thin films were grown by Chemical Bath Deposition (CBD) technique using eqimolar aqueous solutions of zinc chloride, nickel chloride and thiourea as precursor. Silicon glass substrates were placed in glass bottles with polypropylene autoclave screw caps containing the precursors described above, and the bath temperature is maintained at 95°C. X-ray diffraction 28/8 scans showed that the only crystallographic phase present was the hexagonal wurtzite structure. Scanning electron microscopy showed the formation of nanostructures, consisting of hexagonal structures of a few hundred nanometers. The photoluminescence spectra of NiS/ZnS bilayer were recorded at 18-295 K using a cw He-Cd laser (325 nm) and pulsed laser (266 nm). The NiS/ZnS nanostructure exhibit an ultraviolet emission band centered at ;:::; 3.87eV in the vicinity of the band edge, which is attributed to the well-known excitonic transition in ZnS. The optical properties such as refractive index, electrical and optical conductivities were determined by using UV- VIS absorption spectrometry. The band gap energy was determined as 1.45 eV.

Toluene is a component of volatile organic compounds which need to be converted into non-poisonous one. Thus, we study the spinel-typed catalyst as NiCo2O4 for total oxidation of toluene because the advantage of spinel catalyst is multi- defective. Based on the sol-gel method, the catalysts NiCo2O4 were successfully prepared with different ratios of Ni/Co. The characteristic properties of catalysts were evaluated by XRD, BET, H2-TPR and EPR experiments. Amongst these ratios, the catalyst with ratio Ni/Co as 0.5 had the best activity in the total oxidation of toluene, as 100% conversion reached at 250 oC.

Abstract. Remote sensing of greenhouse gases (GHGs) in cities,
where high GHG emissions are typically associated with heavy aerosol
loading, is challenging due to retrieval uncertainties caused by the imperfect
characterization of scattering by aerosols. We investigate this problem by
developing GFIT3, a full physics algorithm to retrieve GHGs (CO2 and
CH4) by accounting for aerosol scattering effects in polluted urban
atmospheres. In particular, the algorithm includes coarse- (including sea
salt and dust) and fine- (including organic carbon, black carbon, and
sulfate) mode aerosols in the radiative transfer model. The performance of
GFIT3 is assessed using high-spectral-resolution observations over the Los
Angeles (LA) megacity made by the California Laboratory for Atmospheric
Remote Sensing Fourier transform spectrometer (CLARS-FTS). CLARS-FTS is
located on Mt. Wilson, California, at 1.67 km a.s.l. overlooking the LA
Basin, and it makes observations of reflected sunlight in the near-infrared
spectral range. The first set of evaluations are performed by conducting
retrieval experiments using synthetic spectra. We find that errors in the
retrievals of column-averaged dry air mole fractions of CO2 (XCO2)
and CH4 (XCH4) due to uncertainties in the aerosol optical
properties and atmospheric a priori profiles are less than 1 % on average. This
indicates that atmospheric scattering does not induce a large bias in the
retrievals when the aerosols are properly characterized. The methodology is
then further evaluated by comparing GHG retrievals using GFIT3 with those
obtained from the CLARS-GFIT algorithm (used for currently operational CLARS
retrievals) that does not account for aerosol scattering. We find a
significant correlation between retrieval bias and aerosol optical depth
(AOD). A comparison of GFIT3 AOD retrievals with collocated ground-based
observations from AErosol RObotic NETwork (AERONET) shows that the developed algorithm produces very
accurate results, with biases in AOD estimates of about 0.02. Finally, we
assess the uncertainty in the widely used tracer–tracer ratio method to
obtain CH4 emissions based on CO2 emissions and find that using
the CH4/CO2 ratio effectively cancels out biases due to aerosol
scattering. Overall, this study of applying GFIT3 to CLARS-FTS observations
improves our understanding of the impact of aerosol scattering on the remote
sensing of GHGs in polluted urban atmospheric environments. GHG retrievals
from CLARS-FTS are potentially complementary to existing ground-based and
spaceborne observations to monitor anthropogenic GHG fluxes in megacities.
Unsupervised classification of simulated magnetospheric regions

Published: October 2021

Abstract. In magnetospheric missions, burst-mode data sampling should be triggered in the presence of processes of scientific or operational interest. We present an unsupervised classification method for magnetospheric regions that could constitute the first step of a multistep method for the automatic identification of magnetospheric processes of interest. Our method is based on self-organizing maps (SOMs), and we test it preliminarily on data points from global magnetospheric simulations obtained with the OpenGGCM-CTIM-RCM code. The dimensionality of the data is reduced with principal component analysis before classification. The classification relies exclusively on local plasma properties at the selected data points, without information on their neighborhood or on their temporal evolution. We classify the SOM nodes into an automatically selected number of classes, and we obtain clusters that map to well-defined magnetospheric regions. We validate our classification results by plotting the classified data in the simulated space and by comparing with k-means classification. For the sake of result interpretability, we examine the SOM feature maps (magnetospheric variables are called features in the context of classification), and we use them to unlock information on the clusters. We repeat the classification experiments using different sets of features, we quantitatively compare different classification results, and we obtain insights on which magnetospheric variables make more effective features for unsupervised classification.
Global time series and temporal mosaics of glacier surface velocities derived from Sentinel-1 data
Authors: Friedl Peter , Seehaus Thorsten , Braun Matthias
Published: October 2021

Abstract. Consistent and continuous data on glacier surface velocity are important
inputs to time series analyses, numerical ice dynamic modeling and glacier
mass flux computations. Since 2014, repeat-pass synthetic aperture radar
(SAR) data have been acquired by the Sentinel-1 satellite constellation as part of
the Copernicus program of the EU (European Union) and ESA (European Space
Agency). It enables global, near-real-time-like and fully automatic
processing of glacier surface velocity fields at up to 6 d temporal
resolution, independent of weather conditions, season and daylight. We
present a new global data set of glacier surface velocities that comprises
continuously updated scene-pair velocity fields, as well as monthly and
annually averaged velocity mosaics at 200 m spatial resolution. The velocity
information is derived from archived and new Sentinel-1 SAR acquisitions by
applying a well-established intensity offset tracking technique. The data
set covers 12 major glacierized regions outside the polar ice sheets and is
generated in an HPC (high-performance computing) environment at the
University of Erlangen-Nuremberg. The velocity products are freely
accessible via an interactive web portal that provides capabilities for
download and simple online analyses: http://retreat.geographie.uni-erlangen.de (last access: 6 October 2021). In this paper, we give
information on the data processing and how to access the data. For the
example region of Svalbard, we demonstrate the potential of our products for velocity time series analyses at very high temporal resolution and assess the quality of our velocity products by comparing them to those generated from very high-resolution TerraSAR-X SAR and Landsat-8 optical (ITS_LIVE, GoLIVE) data. The subset of
Sentinel-1 velocities for Svalbard analyzed in this paper is accessible via
the GFZ Potsdam Data Services under the DOI https://doi.org/10.5880/fidgeo.2021.016 (Friedl et al., 2021). We find that Landsat-8 and Sentinel-1 annual velocity mosaics are in an overall good agreement, but speckle tracking on Sentinel-1 6 d repeat acquisitions derives more reliable velocity measurements over featureless and slow-moving
areas than the optical data. Additionally, uncertainties of 12 d repeat
Sentinel-1 mid-glacier scene-pair velocities have less than half (< 0.08 m d−1) of the uncertainties derived for 16 d repeat Landsat-8 data (0.17–0.18 m d−1).
What are the benefits of lidar-assisted control in the design of a wind turbine?
Authors: Canet Helena , Loew Stefan , Bottasso Carlo L.
Published: October 2021

Abstract. This paper explores the potential benefits brought by the integration of
lidar-assisted control (LAC) in the design of a wind turbine. The study
identifies which design drivers can be relaxed by LAC, as well as by how much
these drivers could be reduced before other conditions become the drivers.
A generic LAC load-reduction model is defined and used to redesign the
rotor and tower of three representative turbines, differing in terms of
wind class, size, and power rating. The load reductions enabled by LAC are
used to save mass, increase hub height, or extend lifetime. For the first
two strategies, results suggest only modest reductions in the levelized
cost of energy, with potential benefits essentially limited to the tower of
a large offshore machine. On the other hand, lifetime extension appears to
be the most effective way of exploiting the effects of LAC.

Intisari—Dalam proses seleksi peserta pelatihan, sebagian besar perusahaan masih menggunakan metode konvensional, yaitu metode seleksi manual, dimana dari mulai pendaftaran hingga pengumuman kelulusan masih dilakukan dengan cara datang langsung ke kantor. Tentunya hal tersebut dinilai kurang efektif di era ini, dikarenakan proses yang berbelit dan butuh waktu yang lama. Dengan adanya e-recruitmen atau proses seleksi secara online, perusahaan dapat melakukan penghematan biaya, brand organisasi dapat lebih dikenal dan memperbesar peluang mendapat calon karyawan yang sesuai kriteria (job specification) yang telah ditetapkan organisasi. Penelitian ini membahas tentang sistem seleksi calon peserta pelatihan kerja, dimana dalam kegiatan seleksi yang masih manual. Sistem ini dirancang untuk dapat mengolah data seleksi calon peserta pelatihan kerja seperti proses registrasi, mengisi data diri calon peserta seleksi, mengelola data test, data hasil seleksi dan mencetak laporan.

Հայերի նկատմամբ զանգվածային բռնությունների նախահիմքերը Ադրբեջանի քաղաքականությունում

This work aims at revealing the premises of the mass violations’ policy in different periods of Azerbaijani statehood and the grounds which the Armenian pogroms were later carried out on.
The objective of the work is to substantiate the consistent and continuous nature of the state-level policy of ethnic discrimination based on the study of separate episodes of such a policy pursued by the Azerbaijani authorities, regardless of the phase features of the Azerbaijani statehood formation and development.
The work is written by a combined examination of facts, applying the principles of historical analysis.
Based on the results of the study, the 1988-1990 mass violations against Armenians in the Soviet Azerbaijan, which expressed themselves in the form of ethnic cleansing and genocidal manifestations, were not just reactive localized crimes, and consequently, the circle of those responsible for them could not have been limited to separate implementers. The violence against Armenians has been an extreme manifestation of a decades-long policy.
