Tools and Methods for Human Robot Collaboration: Case Studies at i-LABS

The collaboration among humans and machines is one of the most relevant topics in the Industry 4.0 paradigm. Collaborative robotics owes part of the enormous impact it has had in small and medium size enterprises to its innate vocation for close cooperation between human operators and robots. The i-Labs laboratory, which is introduced in this paper, developed some case studies in this sense involving different technologies at different abstraction levels to analyse the feasibility of human-robot interaction in common, yet challenging, application scenarios. The ergonomics of the processes, safety of operators, as well as effectiveness of the cooperation are some of the aspects under investigation with the main objective of drawing to these issues the attention from industries who could benefit from them

Avanços no Programa de Erradicação da Cydia pomonella no Brasil.

A Cydia pomonella é uma das mais importantes pragas da maçã e da pera nas principais regiões de produção dessas frutas. Em muitos países o Azinfós-rnetil ainda é o inseticida mais utilizado para o seu controle e são realizadas, em muitos casos, mais de 10 aplicações durante a safra.bitstream/item/200756/1/12801-2011-p.5.pd

Detection of herbicides in water bodies of the Samambaia River sub-basin in the Federal District and eastern Goiás.

The objective of this study was to identify and quantify herbicide residues in water samples of rain, cisterns, streams, ponds, springs, semi-artesian wells, dams and a river in the Rio Samambaia sub-basin in the Federal District and eastern Goiás. A total of 287 samples were collected from 20 farms in the sub-basin in the rainy (February, summer) and dry (August, winter) seasons in 2016. Aminomethylphosphonic acid (AMPA, a glyphosate metabolite), clethodim, chlorimuron-ethyl, diuron, fluazifop acid (a fluazifop-p-butyl metabolite and the active ingredient), haloxyfop acid (a haloxyfop-methyl metabolite and the active ingredient), imazamox, mesotrione, metsulfuron, nicosulfuron and pendimethalin were not identified in any water sample. In the rainy season, approximately 99% of the samples contained residues at least one of the evaluated herbicides; in the dry season (, 100% of the samples contained residues of at least one of the evaluated herbicides. When considering only detection frequency, metribuzin, atrazine, clomazone and haloxyfop-methyl were the main herbicides found in the water of the Samambaia River sub-basin. In turn, based on levels higher than the limit of quantification, the main compounds detected were atrazine, clomazone, haloxyfop-methyl and glyphosate. In both seasons, the highest relative concentrations of herbicides for the rainy and dry seasons were found in spring water, 25% and 56%, respectively, and dam water, 23% and 16%, respectively

Carotenoides totais em acessos de Cucurbita maxima do banco ativo de germoplasma de cucurbitáceas da embrapa clima temperado.

Os agricultores do Sul do Brasil cultivam uma grande diversidade de variedades crioulas de abóboras (Cucurbita moschata, C. maxima, C. pepo, C. ficifolia e C. argyrosperma).Os frutos de Cucurbita maxima são uma rica fonte de nutrientes importantes para a saúde humana, dentre os quais se destacam os carotenoides. O objetivo deste trabalho foi avaliar o teor de carotenoides totais em acessos de Cucurbita maxima do Banco Ativo de Germoplasma (BAG) de Cucurbitáceas da Embrapa Clima Temperado. Foram analisados nove acessos de variedades crioulas procedentes do Sul do Brasil. Para a determinação do teor de carotenoides totais foi utilizado o método de Talcott e Howard com modificações. Os resultados foram calculados através de uma curva padrão de ?-caroteno e expressos em ?g de ?-caroteno por gramas de amostra fresca. As médias obtidas para cada uma das determinações foram comparadas entre si pelo teste de Duncan a 5% de probabilidade. O acesso com maior valor médio de carotenoides totais apresentou 221,92 ?g/g, enquanto que o menor valor de carotenoides totais encontrado foi de 22,64 ?g/g. O BAG da Embrapa Clima Temperado conserva acessos de C. maxima com variabilidade genética para teores de carotenoides totais na polpa de frutos maduros

Levantamento dos dados de passaporte e caracterização de acessos do banco ativo de germoplasma de capsicum da Embrapa clima temperado.

O Brasil é um importante centro secundário de espécies domesticadas de pimentas do gênero Capsicum. Muitos agricultores cultivam as variedades crioulas de Capsicum, que são resultados de vários ciclos de seleção por eles realizada. Estes recursos genéticos vêm sofrendo ação da erosão genética, devido à substituição de culturas ou abandono da atividade agrícola. Em função da grande importância de conservar esse germoplasma, a Embrapa Clima Temperado (Pelotas, RS) vem desde 2002 realizando o resgate de variedades locais de Capsicum, as quais são conservadas no Banco Ativo de Germoplasma (BAG) de Capsicum. O presente trabalho tem como objetivo apresentar a situaçãoatual do Banco Ativo de Germoplasma de Capsicum da Embrapa Clima Temperado, com base no levantamento dos dados de passaporte e de caracterização dos acessos. O BAG de Capsicum da Embrapa Clima Temperado mantém em seu acervo 324 acessos, a maioria deles proveniente de coletas realizadas no Rio Grande do Sul. Fazem parte do acervo do banco acessos de C. annuum, C. baccatum, C. frutescens, C. chinense, C. pubescens, C. galapagoense e C. lanceolatum. Foram submetidos à caracterização morfológica 51,2 % dos acessos, à caracterização química 14,8% e à caracterização molecular 6,1%. Foram avaliados agronomicamente 5,5% dos acessos. Os resultados obtidos demonstram que o BAG de Capsicum da Embrapa Clima Temperado reúne importante diversidade genética de variedades crioulas de pimentas, o que evidencia a importância desse banco

Flight Envelope Information-Augmented Display for Enhanced Pilot Situation Awareness

This paper presents an interface system display which is conceived to improve pilot situation awareness with respect to a flight envelope protection system developed for a mid-sized transport aircraft. The new display is designed to complement existing cockpit displays, and to augment them with information that relates to both aircraft state and the control automation itself. In particular, the proposed display provides cues about the state of automation directly in terms of pilot control actions, in addition to flight parameters. The paper also describes a forthcoming evaluation test plan that is intended to validate the developed interface by assessing the relevance of the displayed information, as well as the adequacy of the display layout

HIV RNA, CD4+ Percentage, and Risk of Hepatocellular Carcinoma by Cirrhosis Status.

BackgroundDespite increasing incidence of hepatocellular carcinoma (HCC) among HIV-infected patients, it remains unclear if HIV-related factors contribute to development of HCC. We examined if higher or prolonged HIV viremia and lower CD4+ cell percentage were associated with HCC.MethodsWe conducted a cohort study of HIV-infected individuals who had HIV RNA, CD4+, and CD8+ cell counts and percentages assessed in the Veterans Aging Cohort Study (1999-2015). HCC was ascertained using Veterans Health Administration cancer registries and electronic records. Cox regression was used to determine hazard ratios (HR, 95% confidence interval [CI]) of HCC associated with higher current HIV RNA, longer duration of detectable HIV viremia (≥500 copies/mL), and current CD4+ cell percentage less than 14%, adjusting for traditional HCC risk factors. Analyses were stratified by previously validated diagnoses of cirrhosis prior to start of follow-up.ResultsAmong 35 659 HIV-infected patients, 302 (0.8%) developed HCC over 281 441 person-years (incidence rate = 107.3 per 100 000 person-years). Among patients without baseline cirrhosis, higher HIV RNA (HR = 1.25, 95% CI = 1.12 to 1.40, per 1.0 log10 copies/mL) and 12 or more months of detectable HIV (HR = 1.47, 95% CI = 1.02 to 2.11) were independently associated with higher risk of HCC. CD4+ percentage less than 14% was not associated with HCC in any model. Hepatitis C coinfection was a statistically significant predictor of HCC regardless of baseline cirrhosis status.ConclusionAmong HIV-infected patients without baseline cirrhosis, higher HIV RNA and longer duration of HIV viremia increased risk of HCC, independent of traditional HCC risk factors. This is the strongest evidence to date that HIV viremia contributes to risk of HCC in this group
