Manejo da morte descendente (Botryodiplodia theobromae + Lasiodiplodia theobromae) na produção integrada de manga.

O manejo de doenças na Produção Integrada de Manga (PI - Manga) tem como ferramenta a prática do monitoramento de doenças, cuja metodologia, hoje ajustada, traz maior segurança de cultivo para os mangicultores. Neste monitoramento, é necessário que o operador conheça todas as expressões dos sintomas que o patógeno pode causar, como, também, as partes das plantas de maior preferência, a fenologia da cultura, a idade de maior ou menor suscetibilidade e as condições climáticas ou época de ocorrência. A morte descendente, por exemplo, apresenta sintomas em todos os órgãos da planta, em qualquer idade e em todas as fases fenológicas da cultura.bitstream/CPATSA/33053/1/INT62.pd

Massage in the prevention and treatment of delayed onset muscle soreness: an updated systematic review

El masaje es una de las terapias más utilizadas para aliviar el dolor muscular tardío (DMT). El objetivo del presente estudio fue determinar la efectividad del masaje en el tratamiento del DMT, para lo cual se llevó a cabo una revisión sistemática en las bases de datos, Pubmed, Scopus, SportDiscus, Web of Science y el buscador Google académico, usando las palabras clave delayed onset muscle soreness y exercise induced muscle damage combinado con massage. Se incluyeron en el estudio 23 artículos en los cuales el 78% mostró disminución del DMT mientras que en el restante 22% no hubo mejoras o bien empeoró. El análisis de los estudios permite concluir que el masaje es una terapia efectiva en el tratamiento del dolor muscular tardío

Identification of protein-coding and non-coding RNA expression profiles in CD34+ and in stromal cells in refractory anemia with ringed sideroblasts

<p>Abstract</p> <p>Background</p> <p>Myelodysplastic syndromes (MDS) are a group of clonal hematological disorders characterized by ineffective hematopoiesis with morphological evidence of marrow cell dysplasia resulting in peripheral blood cytopenia. Microarray technology has permitted a refined high-throughput mapping of the transcriptional activity in the human genome. Non-coding RNAs (ncRNAs) transcribed from intronic regions of genes are involved in a number of processes related to post-transcriptional control of gene expression, and in the regulation of exon-skipping and intron retention. Characterization of ncRNAs in progenitor cells and stromal cells of MDS patients could be strategic for understanding gene expression regulation in this disease.</p> <p>Methods</p> <p>In this study, gene expression profiles of CD34⁺cells of 4 patients with MDS of refractory anemia with ringed sideroblasts (RARS) subgroup and stromal cells of 3 patients with MDS-RARS were compared with healthy individuals using 44 k combined intron-exon oligoarrays, which included probes for exons of protein-coding genes, and for non-coding RNAs transcribed from intronic regions in either the sense or antisense strands. Real-time RT-PCR was performed to confirm the expression levels of selected transcripts.</p> <p>Results</p> <p>In CD34⁺cells of MDS-RARS patients, 216 genes were significantly differentially expressed (q-value ≤ 0.01) in comparison to healthy individuals, of which 65 (30%) were non-coding transcripts. In stromal cells of MDS-RARS, 12 genes were significantly differentially expressed (q-value ≤ 0.05) in comparison to healthy individuals, of which 3 (25%) were non-coding transcripts.</p> <p>Conclusions</p> <p>These results demonstrated, for the first time, the differential ncRNA expression profile between MDS-RARS and healthy individuals, in CD34⁺cells and stromal cells, suggesting that ncRNAs may play an important role during the development of myelodysplastic syndromes.</p

Tendências e ganhos genéticos para pesos calculados aos 120 e 240 dias de idade de bovinos da raça Nelore Mocho.

Objetivou-se estimar a tendência genética relativa aos pesos aos 120 (P120) e 240 (P240) dias de idade em animais Nelore Mocho. Foram utilizadas informações de 42.397 animais nascidos de 1995 a 2011, cedidas pela empresa Guaporé Agropecuária. O grupo de contemporâneos foi formado por meio da concatenação de fatores não genéticos que afetaram significativamente, como fazenda-retiro, ano e a estação de nascimento do animal e lote de manejo da respectiva característica. As tendências genéticas foram preditas por meio do software MTDFREML. As tendências e ganhos genéticos nos permite avaliar a mudança ocasionada por um processo de seleção em determinada característica ao longo dos anos. As tendências genéticas mostraram que nos anos de 2005 e 2009, tanto para P120 como para P240, ocorreram quedas bruscas dos valores genéticos. Os ganhos genéticos foram de 0,077 kg e 0,197 kg para P120 e P240, respectivamente. Para peso aos 120 e 240 dias de idade os pesos passaram de 120,55 kg e 183,3 kg para 157,93 kg e 201,43 kg, respectivamente. As tendências genéticas apresentaram progresso genético positivo apesar das quedas, indicando a necessidade de redefinição dos critérios de seleção. E os ganhos genéticos apontaram o quanto o rebanho irá progredir, e que a seleção reflete de maneira eficiente para a promoção do melhoramento genético do rebanho

Simple heuristics for the assembly line worker assignment and balancing problem

We propose simple heuristics for the assembly line worker assignment and balancing problem. This problem typically occurs in assembly lines in sheltered work centers for the disabled. Different from the classical simple assembly line balancing problem, the task execution times vary according to the assigned worker. We develop a constructive heuristic framework based on task and worker priority rules defining the order in which the tasks and workers should be assigned to the workstations. We present a number of such rules and compare their performance across three possible uses: as a stand-alone method, as an initial solution generator for meta-heuristics, and as a decoder for a hybrid genetic algorithm. Our results show that the heuristics are fast, they obtain good results as a stand-alone method and are efficient when used as a initial solution generator or as a solution decoder within more elaborate approaches.Comment: 18 pages, 1 figur

Using AR interfaces to support industrial maintenance procedures

Industries are becoming more and more digitized to better implement intelligent and predictive maintenance support systems, aligned with Industry 4.0, which requires the progressive digitization of data collection and processes. Maintenance interventions, in an evolving technological context, are increasingly more complex and difficult for technicians to perform. In these environments, the use of Augmented Reality (AR) to help assist and guide in the maintenance operations, can accomplish a considerable gain in productivity. AR allows to superimpose information objects in real scenes, such as text, images, audiovisuals, and 2D/3D model animations, making available contextual information about the process, based on location and perspective. This paper describes the design and implementation of a prototype augmented reality application to support maintenance tasks inside a metal stamping production unit, that produces components for the automotive sector. It aims to train and guide personnel during the maintenance operations, and offering an extra channel to reach expert help.2411-78B2-7CDB | Pedro Miguel MoreiraN/

The multi-objective assembly line worker integration and balancing problem of type-2

[EN] The consideration of worker heterogeneity in assembly lines has received a fair amount of attention in the literature in the past decade. Most of this exploration uses as motivation the example of assembly lines in sheltered work centers for the disabled. Only recently has the community started looking at the situation faced in assembly lines in the general industrial park, when in the presence of worker heterogeneity. This step raises a number of questions around the best way to incorporate heterogeneous workers in the line, maximizing their integration while maintaining productivity levels. In this paper we propose the use of Miltenburg's regularity criterion and cycle time as metrics for integration of workers and productivity, respectively. We then define, model and develop heuristics for a line balancing problem with these two goals. Results obtained through an extensive set of computational experiments indicate that a good planning can obtain trade-off solutions that perform well in both objectives.This research was supported by CAPES -Brazil and MEC-Spain (coordinated project CAPES DGU 258-12/PHB2011-0012-PC ) and by FAPESP -Brazil (grant number: 2010/19983-6 ).Moreira, MC.; Pastor, R.; Costa, A.; Miralles Insa, CJ.
