Authors: Zhang Jing , Qian Jia-Yi , Bian Yue-Hong , Liu Xiao , Wang Chun-Lei
Published: February 2022

Seed dormancy transition is a vital developmental process for seedling propagation and agricultural production. The process is precisely regulated by diverse endogenous genetic factors and environmental cues. Callery pear (Pyrus calleryana Decne) is an important rootstock species that requires cold stratification to break seed dormancy, but the mechanisms underlying pear seed dormancy release are not yet fully understood. Here, we analyzed the transcriptome profiles at three different stages of cold stratification in callery pear seeds using RNA sequencing combined with phytohormone and sugar content measurements. Significant alterations in hormone contents and carbohydrate metabolism were observed and reflected the dormancy status of the seeds. The expressions of genes related to plant hormone metabolism and signaling transduction, including indole-3-acetic acid (IAA) biosynthesis (ASAs, TSA, NITs, YUC, and AAO) genes as well as several abscisic acid (ABA) and gibberellic acid (GA) catabolism and signaling transduction genes (CYP707As, GA2ox, and DELLAs), were consistent with endogenous hormone changes. We further found that several genes involved in cytokinin (CTK), ethylene (ETH), brassionolide (BR), and jasmonic acid (JA) metabolism and signaling transduction were differentially expressed and integrated in pear seed dormancy release. In accordance with changes in starch and soluble sugar contents, the genes associated with starch and sucrose metabolism were significantly up-regulated during seed dormancy release progression. Furthermore, the expression levels of genes involved in lipid metabolism pathways were also up-regulated. Finally, 447 transcription factor (TF) genes (including ERF, bHLH, bZIP, NAC, WRKY, and MYB genes) were observed to be differentially expressed during seed cold stratification and might relate to pear seed dormancy release. Our results suggest that the mechanism underlying pear seed dormancy release is a complex, transcriptionally regulated process involving hormones, sugars, lipids, and TFs.

Recurrent implantation failure (RIF) is a multifactorial condition affecting 10–15% of in vitro fertilization (IVF) couples. Data suggest that functional dysregulation of the endometrial immune system constitutes one of the main pathophysiological mechanisms leading to RIF. The aim of this article is to provide a thorough presentation and evaluation of the role of interleukins (ILs) in the pathogenesis of RIF. A comprehensive literature screening was performed summarizing current evidence. During implantation, several classes of ILs are secreted by epithelial and stromal endometrial cells, including IL-6, IL-10, IL-12, IL-15, IL-18, and the leukemia inhibitory factor. These ILs create a perplexing network that orchestrates both proliferation and maturation of uterine natural killer cells, controls the function of regulatory T and B cells inhibiting the secretion of antifetal antibodies, and supports trophoblast invasion and decidua formation. The existing data indicate associations between ILs and RIF. The extensive analysis performed herein concludes that the dysregulation of the ILs network indeed jeopardizes implantation leading to RIF. This review further proposes a mapping of future research on how to move forward from mere associations to robust molecular data that will allow an accurate profiling of ILs in turn enabling evidence-based consultancy and decision making when addressing RIF patients.

Despite the effectiveness of doxorubicin (DOXO) as a chemotherapeutic agent, dose-dependent development of chronic cardiotoxicity limits its application. The angiotensin-II receptor blocker losartan is commonly used to treat cardiac remodeling of various etiologies. The beta-3 adrenergic receptor agonist mirabegron was reported to improve chronic heart failure. Here we investigated the effects of losartan, mirabegron and their combination on the development of DOXO-induced chronic cardiotoxicity. Male Wistar rats were divided into five groups: (i) control; (ii) DOXO-only; (iii) losartan-treated DOXO; (iv) mirabegron-treated DOXO; (v) losartan plus mirabegron-treated DOXO groups. The treatments started 5 weeks after DOXO administration. At week 8, echocardiography was performed. At week 9, left ventricles were prepared for histology, qRT-PCR, and Western blot measurements. Losartan improved diastolic but not systolic dysfunction and ameliorated SERCA2a repression in our DOXO-induced cardiotoxicity model. The DOXO-induced overexpression of Il1 and Il6 was markedly decreased by losartan and mirabegron. Mirabegron and the combination treatment improved systolic and diastolic dysfunction and significantly decreased overexpression of Smad2 and Smad3 in our DOXO-induced cardiotoxicity model. Only mirabegron reduced DOXO-induced cardiac fibrosis significantly. Mirabegron and its combination with losartan seem to be promising therapeutic tools against DOXO-induced chronic cardiotoxicity.

Published: February 2022

Reverse engineering is the process of creating a digital version of an existing part without any knowledge in advance about the design intent. Due to 3D printing, the reconstructed part can be rapidly fabricated for prototyping or even for practical usage. To showcase this combination, this study presents a workflow on how to restore a motorcycle braking pedal from material SS316L with the Powder Bed Fusion (PBF) technology. Firstly, the CAD model of the original braking pedal was created. Before the actual PBF printing, the braking pedal printing process was simulated to identify the possible imperfections. The printed braking pedal was then subjected to quality control in terms of the shape distortion from its CAD counterpart and strength assessments, conducted both numerically and physically. As a result, the exterior shape of the braking pedal was restored. Additionally, by means of material assessments and physical tests, it was able to prove that the restored pedal was fully functional. Finally, an approach was proposed to optimize the braking pedal with a lattice structure to utilize the advantages the PBF technology offers.

Published: February 2022

The photocatalytic property of Fe oxide minerals has long been considered to play an important role in shaping modern terrestrial environments. However, due to the complexity of natural settings, a precise determination of the band structure of natural goethite has not been achieved. In this work, the mineralogical characteristics of natural goethite samples obtained from Zhushan, China, were systematically studied through X-ray diffraction, transmission electron microscopy, X-ray energy dispersive spectroscopy, and X-ray fluorescence spectroscopy. Afterward, the band structure for both natural and synthetic goethite samples was determined by synchrotron-based X-ray absorption and emission spectra and photoelectron spectroscopy. The band gap of natural goethite (2.25 eV) was narrower than that of its synthetic counterpart (2.55 eV), and the valence band position of natural goethite was slightly lifted (−5.06 eV) compared to that of synthetic goethite (−5.38 eV). Al doping in natural goethite crystal, as revealed by the mineralogical tests, was the main reason that contributed to this difference. The theoretical calculation showed the narrowed band gap was caused by the contribution of Al-2p orbits at the top of the valence band. Therefore, free electrons can be created under light irradiation with a shorter wavelength. The experiments showed that natural goethite can photo-catalytically degrade methyl orange, and the degradation efficiency was better (47.5%) than that of the synthetic goethite group (31.5%). This study, for the first time, revealed the band structure and confirmed the photocatalytic properties of natural goethite, which should play an important role in surface substance evolution and elemental cycling.

Published: February 2022

The dissolution behavior of magnetite deposited on flow mini-channel surfaces within a printed circuit heat exchanger (PCHE) and the corrosion behavior of a STS 316L PCHE material were investigated in an ethylendiaminetetraacetic acid (EDTA)-based chemical cleaning solution at 93 °C. The fouling in the PCHE was simulated using a water-steam circulation loop system. Most of the magnetite deposits were rapidly dissolved in the early stage of the circulation chemical cleaning. An empirical equation for estimating the dissolution percentage was derived as a function of cleaning time. The PCHE material showed excellent corrosion resistance during the chemical cleaning tests. These results indicate the fouling layers in the PCHEs can be removed efficiently by the chemical cleaning process without concern about base metal corrosion.

Published: February 2022

Titanium aluminides are one of the most promising materials in aeronautical and automotive applications. However, their low machinability makes the processing of these alloys quite difficult under sustainability conditions, specially without lubrication. The current study focuses on the turning process of the Ti48Al2Cr2Nb gamma titanium aluminide under dry conditions. As far as we are aware, dry cutting is the most sustainable feature, although it has not been traditionally applied on titanium aluminides due to the accelerated tool wear that the material promotes. The main novelty of this work consists of providing a simple solution for reducing the tool wear based on the inclination of the cutting insert, what is evaluated in terms of tool wear and tool life, cutting forces, cutting temperature, surface integrity of the machined part, as well as its microhardness and microstructural effects. The results shown here clearly point out a better performance of the machining process. This fact could be understood if we take into consideration that an increment of the clearance angle from 6.3° to 11.6° and 15° increases the tool life by five and six times, respectively, using efficient cutting speeds, whose values have increased by 50% with respect to the original cutting conditions. This improvement is explained according to the reduction in the cutting temperature and friction forces in the flank face of the tool. In addition, the use of uncoated carbide inserts may lead to a better behaviour than the coated ones, considering the results obtained for a PVD TiAlN + AlCr2O3 coated insert herein researched.

Published: February 2022

So far, there are no results for research on the biomechanical parameters of giant miscanthus stalks taking into account both the influence of moisture content and the internode, from which the samples were taken. Therefore, the aim of the research was to comprehensively investigate the influence of the internode number (NrNod) and water content (MC) on the values of selected biomechanical parameters (modulus of elasticity and maximum stress) determined using various stress tests (three-point bending and compression along the fibers). The research was carried out for dry stalks of different humidities and for different internodes. The results obtained in this study proved that the independent variables of the water content and the internode number cause a statistically significant influence on the values of the examined biomechanical parameters of the miscanthus stem: the modulus of elasticity in compression, the maximum stress in compression, the modulus of elasticity in bending and the maximum stress in bending. The values of the modulus of elasticity (MOE) increase when increasing the NrNod. For individual internodes, MOE values are higher with a higher MC. The values of the maximum stress (σ) also increase when increasing the internode number. For individual internodes, the σ values are lower with a higher MC.

Published: February 2022

This study investigated the mechanism of delamination damage in the double cantilever beam (DCB) standard test by the use of the strain energy release rate. The curve of the strain energy release rate was verified by the Rise Angle (RA) method. For this purpose, 24-layer carbon fiber/epoxy multidirectional laminates with interface orientations of 0°, 30°, 45°, and 60° were fabricated according to the standard ASTM D5528(13). In the course of this test, acoustic emission (AE) was used for real-time monitoring, and combined with micro visualization, the damage mechanism of composite multidirectional laminates was studied at multiple scales. Combining the AE detection results with micro visualization, it is found that the AE parameters and the damage to multidirectional laminates could realize a one-to-one correspondence. Through the study of the variation of the RA value, load, and strain energy release rate with the crack length, it is proved that the AE parameters can effectively characterize the initiation of delamination damage.
Evaluation of Isomotive Insulator-Based Dielectrophoretic Device by Measuring the Particle Velocity
Authors: Nakabayashi Ryu , Eguchi Masanori
Published: February 2022

Many dielectrophoretic (DEP) devices for biomedical application have been suggested, such as the separation, concentration, and detection of biological cells or molecules. Most of these devices utilize the difference in their DEP properties. However, single-cell analysis is required to evaluate individual properties. Therefore, this paper proposed a modified isomotive insulator-based DEP (iDEP) creek-gap device for straightforward single-cell analysis, which is capable of measurement at a wide frequency band. The proposed iDEP device generates more constant particle velocity than the previous study. The insulator was fabricated using backside exposure for accurate forming. We measured the distribution of the particle velocity and frequency property, using homogeneous polystyrene particles to verify the effectiveness of the proposed device. The results show that the particle velocity distribution was consistent with the distribution of the numerically calculated electric field square (∇Erms2). Furthermore, the velocity measurement, at a wide frequency band, from 10 Hz to 20 MHz, was performed because of the long distance between electrodes. These results suggest that the prop-erties of various particles or cells can be obtained by simple measurement using the proposed device.

COVID-19 is a disease caused by a new type of corona virus, namely Sars-CoV-2. The worsening of the corona virus outbreak requires the government to take a stance so that each individual applies health protocols. Based on data from the UPT Puskesmas Simpang Limun in Medan City, the accumulated number of covid patients from March to July 2020 recorded 21 positive people for Covid-19, 2 people died and 19 people recovered. This study aims to analyze people's behavior in applying health protocols related to Covid-19 in Sudirejo Village, Medan City. This qualitative research was conducted from August to September 2020. Data was collected by conducting interviews and documentation of 8 informants. Data were analyzed using interactive analysis by Miles and Huberman. The results showed that public knowledge in implementing health protocols was still low, people's attitudes were also negative, because they thought that Covid-19 was an issue, besides that there were still many people who had not implemented health protocols. Based on these results, it can be concluded that the application of health protocols is closely related to people's knowledge, attitudes and actions. Therefore it is advisable for the Covid-19 task force to post Covid-19 prevention education posters in each region with a design that attracts attention so that people who do not use social media can read from the poster so that the public can add insight into health protocols related to covid-19.

Esse ensaio visa refletir sobre relevantes dilemas com os quais os cientistas contemporâneos têm que lidar na sua trajetória profissional, pressionados a escolher entre uma sociabilidade baseada numa ética competitiva ou aquela fundada numa ética colaborativa. Busca-se caracterizar o modus operandi subjacente a esses percursos éticos inconciliáveis. E, em seguida, tendo como pano de fundo o contexto científico de estudos sobre riscos, a reflexão se aprofunda na escolha pelo caminho colaborativo tomando como referência a prática profissional e de cidadania de um geógrafo lusitano, o qual faz de seu ofício um recurso estratégico de amarração social do seu lugar de pertença com o meio científico.
A prevenção contra incêndios florestais em tempo de pandemia: A união entre
experiência e inovação
Authors: Bianchi Azevedo Adriana Aparecida , Pimentel Barcelos Fábio
Published: February 2022

Em 2020, diante da pandemia da COVID-19, esses dados de incêndio florestais foram
sobrepostos num mapa com os locais do município onde havia casos da doença. Infelizmente
em muitos locais as duas situações se coincidiam. Um trabalho antes presencial passou a
ser feito pela internet: nascia o NAPCIF On-line (Núcleo Avançado de Prevenção e Combate
ao Incêndio Florestal) com o objetivo de instruir a população em prevenção e primeiro
combate aos incêndios florestais. Através dos grupos formados, a interação entre os
parceiros e o 16⁰GBM facilitou a detecção de focos de incêndio florestal, diminuindo o
número dos mesmos na região analisada e demonstrando a eficiência do trabalho em várias
frentes.
Is native forest an alternative to prevent wildfire in the WUI in Central
Portugal?
Authors: Silva de Oliveira Aline , Sande Silva Joaquim , Gaspar José , Nunes Guiomar Nuno R. G. , Fernandes Paulo M.
Published: February 2022

he expansion of the 2017 mega-fires in Portugal was observed to be locally halted
by native forest patches. Here we present spatial simulation scenarios of fire behaviour
to assess whether native forest cover mitigates fire spread during extreme wildfire
conditions in wildland-urban interface (WUI) areas around Industrial Zones (IZs). Our
results suggest that broadleaved forest cover can reduce fireline intensity and rate of
spread around IZs up to 20 and 8 times, respectively, on average. Thus, our results
support the need to discuss forest management in Portugal to better prevent WUI
fires.
O estudo dos processos erosivos em áreas ardidas em Portugal: perspetiva
geográfica
Authors: Vieira António , Bento-Gonçalves António
Published: February 2022

O estudo dos processos erosivos em Portugal deu os seus primeiros passos na
primeira metade do século XX, mas foi especialmente a partir dos anos 80 do mesmo século
que teve maior expressão. Acompanhando este crescente interesse, e na sequência do
aumento significativo do número de incêndios florestais que se verificou a partir da
década de 70 do século XX, a comunidade científica direcionou a sua atenção para a
análise dos processos erosivos ocorridos em áreas ardidas. Neste texto procura-se fazer
uma breve análise do contributo dos geógrafos portugueses para o estudo da erosão dos
solos ocorrida em áreas afetadas por incêndios florestais, destacando-se o trabalho
desenvolvido pelo Prof. Luciano Lourenço e investigadores que com ele colaboraram na
compreensão deste fenómeno.
Grandes incendios forestales en España y alteraciones de su régimen en las últimas
décadas
Authors: Ubeda Cartañà Xavier , Mataix-Solera Jorge , Francos Marcos , Farguell Joaquim
Published: February 2022

Durante siglos los incendios forestales han tenido lugar en España y han
configurado el paisaje vegetal del país. Lo que se plantea en este artículo es analizar
si ha habido un cambio de régimen de incendios en las últimas décadas. Los resultados
indican que parece ser que sí hay un cambio de régimen, aunque la respuesta es diferente
dependiendo de la ubicación geográfica de los bosques en España. El abandono de las
prácticas forestales, la despoblación de las áreas rurales y los efectos del cambio
climático, pueden ser las causas de este cambio de régimen de incendios.
Adaptaciones de los programas de prevención contra incendios forestales en Chile,
ante un escenario cambio climático
Authors: Castillo Soto Miguel E.
Published: February 2022

os incendios forestales de comportamiento extremo están siendo cada vez más
frecuentes en distintas partes del mundo. En particular, en Chile, ha habido un cambio
adaptativo en la organización de los programas de protección. Un hecho que definió este
cambio fue la catástrofe de 2017 en donde la tormenta de fuego arrasó con 396 mil
hectáreas de bosques en tan sólo 13 días durante el mes de enero, totalizando poco más
de 600 mil en toda la temporada. La acumulación de biomasa seca, la continuidad de las
plantaciones y las condiciones meteorológicas extremas, no permitieron que el fuego
pudiera ser controlado con los medios y sistemas de combate que existían hasta antes de
esa catástrofe. Este artículo señala las principales acciones que se han ejecutado bajo
esta experiencia en un escenario de cambio climático y también los aspectos que han
necesitado adaptaciones para enfrentar este nuevo tipo de emergencias.
As operações de proteção civil nos territórios arquipelágicos nacionais: o emprego
de recursos disponíveis e o reforço das capacidades
Authors: Guerra Neri Luís Manuel
Published: February 2022

Os territórios arquipelágicos portugueses detêm um conjunto de caraterísticas que
os diferenciam do restante território nacional. Têm recursos importantes para a sua
vivência diária, mas não suficientes. A sua economia é muito dependente do exterior. A
ocorrência de fenómenos de várias origens, mas principalmente com origem nas alterações
climáticas são, hoje em dia, cada vez mais frequentes, violentos e imprevisíveis, mesmo
com a evolução dos sistemas de meteorologia. As operações de proteção civil são cada vez
mais complexas, devem ser objeto de um planeamento flexível e abrangente, com a
utilização de todos os recursos disponíveis localmente, o reforço das suas capacidades
em tempo útil e um comando único para a operaçãos.
Gestão territorial do risco na adaptação às alterações climáticas
Authors: O. Tavares Alexandre , P. Areia Neide
Published: February 2022

A atual emergência climática exige não só a implementação de ações de mitigação,
bem como o reforço urgente de estratégias de adaptação nos territórios particularmente
vulneráveis às consequências das mudanças dos padrões climáticos. Considerando o seu
caráter sistémico, advoga-se que os modelos de gestão de riscos podem contribuir
significativamente no sucesso dos processos de adaptação. Assim, e tendo por base os
modelos de gestão do risco, salientam-se os objetivos fundamentais para a consolidação
das ações de adaptação às alterações climáticas. Com base nestes, sugere-se um modelo
territorial de gestão do risco baseado em dez questões principais, no contexto das
alterações climáticas, para o território Português, que consiste em quatro espaços-risco
com características específicas para planeamento, aplicação e monitorização das ações de
adaptação.

Authors: Meira Castro Ana C. , Santos Baptista João , Lima Fuziel Killian Sumaya
Published: February 2022

As operações de colheita florestal são caracterizadas por serem, simultaneamente,
de uma grande exigência física para os operadores e com um elevado risco de ocorrência
de acidentes. Estes acidentes ocupacionais, para além dos problemas que acarretam para
os trabalhadores, implicam prejuízos económicos consideráveis para as empresas e
externalidades socialmente relevantes. Neste trabalho pretende-se elencar os principais
fatores de risco e medidas preventivas nas operações de colheita florestal. A sua
identificação foi efetuada através da análise de trabalhos dos principais autores da
área. O cumprimento dos procedimentos de identificação dos perigos e avaliação dos
riscos, bem como a implementação e cumprimentos das medidas de segurança são fatores
fundamentais para a redução dos índices de sinistralidade no setor.
Conceitos e terminologia em Medicina de Catástrofe. Sinopse
Authors: Bandeira Romero , Gandra Sara
Published: February 2022

Com conceitos e terminologia específicos, a Medicina de Catástrofe vê-se na
absoluta necessidade de estar em permanente adequação com os mesmos sob pena de, na
prática, não poder desempenhar cabalmente a sua humanitária missão. Este nosso trabalho
é, indelevelmente, uma homenagem a uma pessoa – o Prof. Luciano Lourenço - inolvidável
no seu humanismo científico, plasmado num trato humano e social, digno de ser apontado
como um exemplo primordial a ser prosseguido por todos os investigadores, mormente por
aqueles que integram as camadas mais jovens.
