O mosquitinho (Gypsophila paniculata L.), é uma planta utilizada para compor arranjos florais. O objetivo deste trabalho foi avaliar a eficiência da utilização do Humoativo e do Esterco Bovino na caracterização morfológica do mosquitinho. O experimento foi realizado na Casa de Vegetação no Instituto Federal de Educação Ciência e Tecnologia da Bahia – IFBA - Campus de Vitória da Conquista, Bahia. Utilizou-se diferentes proporções de Esterco Bovino - EB e Humoativo - HA, constituindo os seguintes tratamentos: T1: 0% de EB e 0% de HA; T2: 25% de EB e 75% de HA; T3: 50 % de EB e 50 % de HA; T4: 75% de EB e 25% de HA; T5: 100% de EB e 0 % de HA; T6: 0 % de EB e 100 % de HA. O delineamento foi inteiramente ao acaso (DIC), com quatro repetições, totalizando 24 unidades experimentais. A partir do transplante, foram avaliadas Altura da Planta, Número de Hastes Florais, Altura da Haste Floral, Número de Ramificações primárias da haste floral, e Diâmetro da flor. Também foi verificado o peso fresco e seco da planta. Os dados foram submetidos à análise de variância (ANOVA) seguida do teste de média (Tukey a 5%) utilizando-se o programa estatístico SAEG - Statistical Analysis System (GOMES, 1992). O uso do EB e do HA favoreceram o acúmulo do peso fresco da flor, do caule, da raiz e peso fresco total. Ocorrendo o mesmo para peso seco. Todas as variáveis analisadas aumentaram com as doses do EB e HA.

O objetivo do presente estudo foi avaliar a degradação de microcistina–LR no tratamento de água de abastecimento, em sistema convencional seguido de fotocatálise homogênea (UV/H2O2). As condições ótimas para o tratamento convencional foram determinadas em jar test com a dosagem (50 mg.L-1) de Sulfato de Alumínio, pH inicial (6.8) de coagulação e tempo de sedimentação de 15 minutos. Nestas condições as etapas de coagulação, floculação, sedimentação e filtração do método convencional da água mostraram-se eficientes na remoção de cor verdadeira (80%) e turbidez (97%), não sendo satisfatória à remoção da microcistina–LR. Contudo, houve remoção significativa deste micropoluente pelo processo oxidativo avançado (UV/H2O2). Dos seis tratamentos realizados no reator fotocatalítico, apenas aquele de concentração de 1000 mM (UV/H2O2), após 15 minutos de oxidação, atingiu o valor máximo permitido pela Portaria de nº 005/2017 anexo XX para os padrões de potabilidade. Aos 60 minutos do processo, houve uma remoção de 83.3% da microcistina-LR para esta mesma dosagem de H2O2, que atingiu o valor final aproximado de 0.5 μg.L-1 de MC-LR. O método empregado para análise da oxidação da microcistina-LR por CLAE–EM, mostrou-se altamente sensível e rápido na detecção de fragmentos resultantes da oxidação de (UV/H2O2) identificando o aminoácido ADDA presente no analito apartir do fragmento m/z 135 e assim comprovando a eficácia do tratamento. Concluiu-se que a combinação de um tratamento convencional seguido de processo oxidativo avançado (POA) aplicados ao tratamento de água de reservatório eutrofizado, é uma solução eficaz e segura para obtenção de água potável.

The Cancer Registry of Norway organises a population-based breast cancer screening program, where 250 000 women participate each year. The interpretation of the screening mammograms is a manual process, but deep neural networks are showing potential in mammographic screening. Most methods focus on methods trained from pixel-level annotations, but these require expertise and are time-consuming to produce. Through the screenings, image level annotations are however readily available. In this work we present a few models trained from image level annotations from the Norwegian dataset: a holistic model, an attention model and an ensemble model. We compared their performance with that of pretrained models based on pixel-level annotations, trained on international datasets. From this we found that models trained on our local data with image-level annotation gave considerably better performance than the pretrained models from external data, although based on pixel-level annotations.

Published: April 2022

Background
Gut microbiota play a critical role in nutrition absorption and environmental adaptation and can affect the biological characteristics of host animals. The invasive golden apple snail (Pomacea canaliculata) and native Chinese mud snail (Cipangopaludina chinensis) are two sympatric freshwater snails with similar ecological niche in southern China. However, gut microbiota comparison of interspecies remains unclear. Comparing the difference of gut microbiota between the invasive snail P. canaliculata and native snail C. chinensis could provide new insight into the invasion mechanism of P.canaliculata at the microbial level.

Methods
Gut samples from 20 golden apple snails and 20 Chinese mud snails from wild freshwater habitats were collected and isolated. The 16S rRNA gene V3–V4 region of the gut microbiota was analyzed using high throughput Illumina sequencing.

Results
The gut microbiota dominantly composed of Proteobacteria, Bacteroidetes, Firmicutes and Epsilonbacteraeota at phylum level in golden apple snail. Only Proteobacteria was the dominant phylum in Chinese mud snail. Alpha diversity analysis (Shannon and Simpson indices) showed there were no significant differences in gut microbial diversity, but relative abundances of the two groups differed significantly (P < 0.05). Beta diversity analysis (Bray Curtis and weighted UniFrac distance) showed marked differences in the gut microbiota structure (P < 0.05). Unique or high abundance microbial taxa were more abundant in the invasive snail compared to the native form. Functional prediction analysis indicated that the relative abundances of functions differed significantly regarding cofactor prosthetic group electron carrier and vitamin biosynthesis, amino acid biosynthesis, and nucleoside and nucleotide biosynthesis (P < 0.05). These results suggest an enhanced potential to adapt to new habitats in the invasive snail.

A representatividade do corpo entra cada vez mais em crise. Há um corpo que se expõe não só como organismo, mas como potência de conexão entre o mundo e a linguagem. Este texto reflete sobre esse corpo e sobre a escrita de autoria feminina na obra As alegrias da maternidade, de Buchi Emecheta, na perspectiva crítica de autoras como Bibi Bakare-Yusuf, Ifi Amadiume, Oyèronkẹ́ Oyěwùmí, entre outras, e à luz do conceito de escrevivência de Conceição Evaristo. Em Buchi Emecheta, a inversão discursiva e temática do topoi masculino tem como recorte o contexto do período colonial (a diegese do romance) e o período pós-colonial (anos 1970, contexto da produção da obra). Outras narrativas e discursos literários são considerados na discussão no intuito de construir uma tessitura dos papéis do corpo nas (de)codificações coloniais e pós-coloniais da Nigéria.

Published: April 2022

AbstractTraditional semiconductor materials with narrow bandgap are involved in a wide range of important applications such as photodetection, photovoltaics, biosensing, and bioimaging. Recently, narrow bandgap metal halide perovskites (MHPs) have attracted widespread attention with the advantages of low cost, easy synthesis, adjustable bandgap, and high photoluminescence quantum yield. State‐of‐the‐art progress of narrow bandgap MHPs is reviewed with emphasis on the structures, synthesis methods, characterizations, and optoelectronic applications. First, the structures and classifications of different dimensions of narrow bandgap MHPs are introduced. On this basis, a variety of synthetic and stability enhancement strategies of common narrow bandgap MHPs are discussed. Second, the applications of narrow bandgap MHPs for photodetectors, light‐emitting diodes, lasers, sensors, and memories are reviewed. Finally, the authors provide a perspective of current challenges in long‐term stability and fundamental properties, and propose new opportunities for broader fundamental researches and practical applications in the outlook section.

AbstractApart from the energy gap law, control parameters over nonradiative transitions are so far only scarcely regarded. In this work, the impact of both covalence of the lanthanoid–ligand bond and varying bond distance on the magnitude of the intrinsic nonradiative decay rate between the excited 6P5/2 and 6P7/2 spin–orbit levels of Gd3+ is investigated in the chemically related compounds Y2[B2(SO4)6] and LaBO3. Analysis of the temperature‐dependent luminescence spectra reveals that the intrinsic nonradiative transition rates between the excited 6PJ (  J = 5/2, 7/2) levels are of the order of only 10 ms−1 (Y2[B2(SO4)6]:Gd3+: 8.9 ms−1; LaBO3:Gd3+: 10.5 ms−1) and differ due to the different degree of covalence of the GdO bonds in the two compounds. Comparison to the established luminescent Boltzmann thermometer Er3+ reveals, however, that the nonradiative transition rates between the excited levels of Gd3+ are over three orders of magnitude slower despite a similar energy gap and the presence of a single resonant phonon mode. This hints to a fundamental magnetic dipolar character of the nonradiative coupling in Gd3+. These findings can pave a way to control nonradiative transition rates and how to tune the dynamic range of luminescent Boltzmann thermometers.
Understanding the Origin of the Particularly Small and Anisotropic Thermal Expansion of MOF‐74

Published: April 2022

AbstractMetal–organic frameworks often display large positive or negative thermal expansion coefficients. MOF‐74, a material envisioned for many applications, shows a different behavior. Temperature‐dependent X‐ray diffraction reveals particularly small negative (positive) thermal expansion coefficients perpendicular (parallel) to the hexagonally arranged pores. These trends are explained by combining density‐functional theory calculations with the Grüneisen theory of thermal expansion, which allows tracing back thermal expansion to contributions of individual phonons. On the macroscopic level, the small thermal expansion coefficients arise from compensation effects caused by the large coupling between perpendicular stress and strain and by the small magnitudes of the mean Grüneisen tensor elements, 〈γ〉. These provide information on how strains impact phonon frequencies. To understand the small value of 〈〉, the individual mode contributions are analyzed using the corresponding atomic motions. This reveals that only the lowest frequency modes up to ≈3 THz provide non‐negligible contributions, such that 〈〉 drops sharply at higher temperatures. These considerations reveal, how the details of the anharmonic properties of specific phonon bands determine the magnitude and sign of thermal expansion in a prototypical material like MOF‐74. Beyond that, the authors also discuss, how the choice of the theoretical methodology impacts the obtained results.

AbstractA soft gripper inspired by the glowing sucker octopus (Stauroteuthis syrtensis)’ highly evolved grasping capability enabled by the umbrella‐shaped dorsal and ventral membrane between each arm is presented here, comprising of a 3D‐printed linkage mechanism used to actuate a modular mold silicone‐casting soft suction disc to deform. The soft gripper grasp can lift objects using the suction generated by the pump in the soft disc. Moreover, the protruded funnel‐shaped end of the deformed suctorial mouth can adapt to smooth and rough surfaces. Furthermore, when the gripper contacts the submerged target objects in a turbid environment, local suctorial mouth arrays on the suction disc are locked, causing the variable flow inside them, which can be detected as a tactile perception signal to the target objects instead of visual perception. Aided by the 3D‐printed linkage mechanism, the soft gripper can grasp objects of different shapes and dimensions, including flat objects, objects beyond the grasping range, irregular objects, scattered objects, and a moving turtle. The results report the soft gripper's versatility and demonstrate the vast application potentials of self‐adaptive grasping and sensing in various environments, including but are not limited to underwater, which is always a key challenge of grasping technology.

Published: April 2022

AbstractPredicting granular flow using continuum approaches is fundamental to advance granular physics and industrial applications. Previous studies have demonstrated that continuum modeling can capture some hydrodynamic instability analogs in monodisperse granular materials. Recently, a family of gravitational instabilities was found between two types of grains, including a Rayleigh–Taylor analog, a granular bubble rising, a granular droplet splitting and particle segregation. The high packing fraction and bi‐disperse nature of these flows allow for new challenges to continuum models. Herein, we applied multifluid modeling (MFM) that treats the gas phase and two separate granular phases as fully interpenetrating continua to simulate these instabilities and compared them with newly conducted experiments. Simulation results reproduced all of the four instabilities and demonstrated that frictional particle stress and solids–solids drag are needed to capture critical qualitative flow features. This study can serve as a basis for challenging future particle stress and solids–solids drag models.

AbstractWild nonhuman primates (NHP) are considered natural hosts of a protozoan parasite from the genus Leishmania, the etiological agent of leishmaniasis. It is important to study the population of this infectious agent in zoo animals to establish surveillance and control mechanisms in Sorocaba through the application of a One Health approach, this is where human–animal–environment health and disease interface and can aid in the protection of endangered species. This study aimed to identify Leishmania infantum and Leishmania braziliensis in NHP living in a city where leishmaniasis is endemic. DNA was extracted from 48 NHP and analyzed using polymerase chain reaction primers that are specific for the species L. infantum and L. braziliensis. The results of our research revealed the first report of L. infantum and L. braziliensis naturally infecting primates at Sorocaba zoo. One primate from the species Plecturocebus vieirai was positive for L. infantum and five primates (four Alouatta caraya and one Ateles chamek) were positive for L. braziliensis. This indicates a possible role of these animals on the maintenance of these parasites.

AbstractWährend supramolekulare Wirte mit der Fähigkeit zum Binden und Transportieren von Anionen und Ionenpaaren heutzutage weit verbreitet sind, sind selbstassemblierte Architekturen immer noch selten, obwohl sie einen inhärenten Mechanismus für die Freisetzung der Gastionen bieten. In dieser Arbeit beschreiben wir die dynamisch kovalente Selbstassemblierung von dreizähnigen, Harnstoff‐basierten Kryptaten, die durch zwei Orthoester‐Brückenköpfe verbunden sind. Diese Wirte zeigen Affinitäten für Anionen wie Cl−, Br−und I−in moderater Höhe, die typischerweise vorteilhaft für Anwendungen im Membrantransport sind. In bislang beispiellosen Experimenten konnten wir das Ionenpaar Cs⋅Cl dissoziieren, indem wir simultan zwei passende Orthoester‐Wirte für das Cs+and das Cl−Ion selbstassemblierten.
Models for predicting organic micropollutant breakthrough in carbon adsorbers based on water quality, adsorbate properties, and rapid small‐scale column tests
Authors: Kearns Joshua P. , Kennedy Anthony M. , Shimabuku Kyle K. 
Published: April 2022

AbstractRapid small‐scale column tests (RSSCTs) have been developed for simulating the removal of organic micro‐pollutants (OMPs) in full‐scale fixed‐bed carbon adsorbers to reduce time, materials, and labor costs. However, when dissolved organic matter (DOM) is present, OMP breakthrough profiles obtained from RSSCTs often do not match those at full‐scale because DOM fouling scales differently than OMP adsorption for different‐sized adsorbent particles. To overcome this limitation, single and multiple linear regression analyses were used to develop relationships between DOM concentration, OMP physical–chemical properties (log D, Abraham solvation parameters), and early (10%) OMP breakthrough at full‐scale with and without RSSCT data. It was found that statistically significant regressions could be developed using the largest database assembled to date consisting of 175 RSSCT and full‐/pilot‐scale data pairs, including activated carbons generated from bituminous coal, lignite, coconut shells, and wood‐based biochar, 58 OMPs with a range of adsorbabilities, and waters containing DOM from diverse origins.

Prognose der Schalldämmung von Außenwänden mit Wärmedämm‐Verbundsystem – Entwicklung des Prognoseverfahrens als Beitrag zur Überarbeitung der ÖNORM B 8115‐4
Authors: Neusser Maximilian , Dolezal Franz 
Published: April 2022

AbstractWärmedämm‐Verbundsysteme (WDVS) stellen nicht nur eine kostengünstige Möglichkeit der Reduktion des Wärmeverlustes durch Außenwände dar, sondern haben, je nach Material, auch Auswirkungen auf das Schalldämm‐Maß dieser Bauteile. Das vorliegende Prognosemodell für das bewertete Schalldämm‐Maß von Außenwänden mit WDVS wurde in dieser Form in die derzeit in Überarbeitung befindlichen österreichischen bauakustischen Prognosenorm ÖNORM B 8115‐4 aufgenommen und stellt deren derzeitigen Bearbeitungsstand dar. Das erwähnte Modell bedeutet nicht nur einen signifikanten Sprung in der Prognosegenauigkeit, sondern führt erstmals auch alle wesentlichen, in Österreich gebräuchlichen, Massivwände in ein Modell zusammen. Es ist damit möglich, das bewertete Schalldämm‐Maß von Außenwänden aus Ziegel, Beton und Massivholz mit WDVS in einfacher und transparenter Weise zu berechnen. Darüber hinaus ermöglicht das Modell auch die Ermittlung des Spektrum‐Anpassungswertes Ctr des Schalldämm‐Maßes, wodurch die Eignung des Außenbauteils zum Schutz vor Verkehrslärm durch den Planer charakterisierbar wird. Das vorliegende, materialübergreifende Prognosemodell resultiert aus der Zusammenführung früherer, materialspezifischer Forschungsarbeiten der beiden Autoren zu diesem Thema.
