What Has Changed During the COVID-19 Pandemic? - The Effect on an Academic Breast Department in Portugal

Introduction: One year ago, Portugal entered its first lockdown because of the coronavirus disease-2019 (COVID-19) pandemic. The impact of this on delays in cancer diagnosis and treatment is a major concern, which may negatively affect the outcomes of these patients. Materials and methods: This retrospective, single-center analysis compared the clinical and pathological characteristics of breast cancer (BC) patients referred to a medical oncology first appointment between March 2020 and 2021, with the same period in the previous year. Results: Strikingly, there was a 40% reduction in the number of BC patients during lockdown. However, there was a statistically significant increase in the proportion of metastatic BC patients admitted for the first time for systemic therapy (13.6% vs. 28.9%, p = 0.003). Additionally, a statistically significant increase in the number of patients with bilateral early BC at diagnosis after March 2020 was found (7.2% vs. 1.9%, p = 0.043). Conclusion: These findings support international recommendations for an accelerated restoration of BC screening, to reduce incidence of advanced breast cancer at diagnosis and mitigate the expected impact of the COVID-19 pandemic on patients with cancer. Further work is needed to examine in detail the impact of measures to manage the COVID-19 pandemic on breast cancer outcomes.info:eu-repo/semantics/publishedVersio

Distinguishing sequences for partially specified FSMs

Distinguishing Sequences (DSs) are used inmany Finite State Machine (FSM) based test techniques. Although Partially Specified FSMs (PSFSMs) generalise FSMs, the computational complexity of constructing Adaptive and Preset DSs (ADSs/PDSs) for PSFSMs has not been addressed. This paper shows that it is possible to check the existence of an ADS in polynomial time but the corresponding problem for PDSs is PSPACE-complete. We also report on the results of experiments with benchmarks and over 8 * 106 PSFSMs. © 2014 Springer International Publishing

Study of several varieties of tree crowns on different rootstocks of mango (Mangifera indica L.)

O objetivo deste trabalho foi verificar a interferência copa x porta-enxerto no desenvolvimento da mangueira. As alturas e os diâmetros das copas foram tomadas uma vez em 1981, quando as 210 plantas atingiram 15 anos de idade. As variedades de copas estudadas foram as seguintes: Extrema, Oliveira Neto, Carlota, Imperial, Pahiri e Bourbon. Os porta-enxertos utilizados foram Espada, Extrema, Olivara Neto, Carlota, Coco, Pahiri e Bourbon. Os dados foram analisados e a comparação das médias foi feita através do teste de Tukey em nível de 5% de probabilidade. O estudo mostrou que as variedades de copa, Olivara Neto, Extrema e Bourbon atingiram uma altura e um diâmetro maior que as demais variedades.The aim of this paper was to investigate the influence of the combination tree crown + rootstock on mango tree performance. The trees were selected according to height and crown diameter, measured once in 1981, using 210 trees, 15 years old at the beginning of the experiment. The Extrema, Espada, Oliveira Neto, Carlota, Bourbon, Coco and Pahiri varieties were used as rootstock and Extrema, Pahiri, Imperial, Oliveira Neto, Cariota e Bourbon were utilized as scions for tree crown development. Data were analysed by classical statistics, comparing means through the Tukey test, at a probability level of 5%. The crowns Oliveira Neto, Extrema e Bourbon showed the highest heights and diametres

Dynamic separation on a pitching and surging airfoil as a model for flow over vertical axis wind turbine blades

Vertical axis wind turbine (VAWT) blades undergo dynamic separation due to the large angle of attack variation they experience during a turbine rotation. The flow over a single blade was modeled using a sinusoidally pitching and surging airfoil in a constant free stream flow at a mean chord Reynolds number of 10^5. Two-dimensional, time resolved velocity fields were acquired using particle image velocimetry (PIV). Vorticity contours were used to visualize shear layer and vortex activity. A low order model of dynamic separation was developed using Dynamic Mode Decomposition (DMD). A primary and secondary dynamic separation mode were identified as the critical drivers for the unsteady flow field

Effects of Different Number of Sets of Resistance Training on Flexibility

International Journal of Exercise Science 10(3): 354-364, 2017. The aim of this study was to investigate the effects of six months of training with three different number of sets of resistance training on flexibility in young men. Forty-seven men (mean ± SD age = 24 ± 1yrs; body mass = 79.39 ± 9.12 kg; height = 174.5 ± 5.6 cm) were randomly divided into three training groups performing either one set (G1S), three sets (G3S), or five sets (G5S) of all exercises in a resistance training session or a control group (CG). All groups were assessed pre- and post-training for Sit-and-Reach test and range of motion of 10 joints using goniometry. The training protocol included three weekly sessions and was composed of nine exercises performed at a moderate intensity (eight to 12RM). The results demonstrated significant differences pre- to post-training for the Sit-and-Reach test for all training groups; however, only the G5S showed significant differences when compared to the CG (31.04 ± 5.94cm vs. 23.56 ± 6.76cm, respectively; p \u3c 0.05). Of the ten joint movements measured, there were range of motion increases only to shoulder flexion (G1S), shoulder extension (G3S), elbow flexion (G3S), and knee flexion (G3S) when comparing pre- to post-training (p \u3c 0.05). In conclusion, different resistance training volumes improved flexibility for some joints of young men. These findings indicate that performing only resistance training can result in increases in flexibility

Produtividade e qualidade do caldo de sorgo sacarino sob diferentes manejos de plantas daninhas.

A utilização de sorgo sacarino como atividade aditiva, no sistema de produção de açúcar e álcool, tem sido estudada com destaque. Dentre os entraves relacionados ao cultivo das culturas em rotação está o manejo de plantas daninhas utilizando-se herbicidas, principalmente em função da falta de informações acerca de produtos utilizados na cultura. Nesse sentido, objetivou-se com os trabalhos avaliar a produtividade e qualidade do caldo de sorgo sacarino sob diferentes manejos de plantas daninhas. O experimento foi organizado em blocos casualizados, em esquema de parcelas subdivididas com quatro repetições. Os herbicidas foram aplicados na pós-emergência, quando as plantas apresentavam quatro ou cinco folhas. De uma forma geral, o herbicida bentazon se mostrou propicio para utilização nos cultivares BRS 504, 506 e 508, quando avaliados biomassa das plantas de sorgo. Os mesmos resultados foram encontrados quando aplicado atrazine nas cultivares BRS 504 e 506. Linuron e tembotrione interferem no rendimento e no brix dos cultivares avaliados

Advances in technology transference: the experience of integrated crop-livestock-forestry (ICLF) adoption in Tocantins State.

In 2010 the Brazilian Government established a goal to reduce the emissions of greenhouse gases (GHG) by agriculture from 36.1 up to 38.9% in ten years (2010 -2020). To contribute for reaching part of this purpose in Tocantins State, Embrapa and other research and extension services partners have been conducting a project of technology transference on sustainable agricultural practices, including integrated crop-livestock-forestry (ICLF), since 2012
