Pipeline de detecção de laranjas a partir de vídeos.

RESUMO - A detecção de frutos utilizando vídeos, adquiridos em laranjais, é um processo que envolve a utilização de vários sistemas. Cada um é responsável por uma etapa do processo de detecção, sendo que o resultado de um serve como entrada para o outro. Para que o processo seja executado corretamente é necessário a validação dos resultados em cada etapa, antes do início da próxima etapa. Caso o resultado de uma etapa não seja satisfatória, é necessário executar a etapa anterior utilizando outros parâmetros de ajustes, até que se obtenha um resultado aceitável. Este procedimento pode ser executado manualmente, mas é muito trabalhoso. Este trabalho apresenta uma solução baseada no conceito de máquina de estado finito para automatizar o processo de detecção de frutos.Evento online. CIIC 2021

Goat incubator: can bovine oocytes be matured in the uterine horn of a goat?

Abstract We used a goat as a live incubator, along with associated nonsurgical embryo transfer techniques, to perform ex situ (in vivo) maturation of bovine oocytes. Immature bovine cumulus-oocyte complexes (COCs) aspirated from 3-8 mm follicles from slaughterhouse ovaries were randomly split into two groups for in vitro (IVM; n = 38) and ex situ maturation (ESM; n = 40). IVM was performed for a period of 24 h at 38.5 ºC and with 5% CO2 in the air of maximum humidity. For ESM, a presynchronized nulliparous goat (12 months old) received 40 immature COCs in the uterine horn apiece, via the transcervical route. After 24 h the structures were retrieved through uterine flushing. Analyses of nuclear maturation and lipid quantification were performed on oocytes from both groups. Fluorescent intensity was compared using the Student?s t-test. Forty-seven percent of the structures were recovered after uterine flushing (19/40). The nuclear maturation rate was 94.5% (18/19) and 81.6% (31/38) for the ESM and IVM groups, respectively. In vitro-matured COCs contained more lipid droplets, expressed as a higher amount (p < 0.05) of emitted fluorescent light than ex situ-matured COCs (858 ± 73 vs. 550 ± 64 arbitrary fluorescence units, respectively). This is the first report to associate nonsurgical embryo transfer techniques and a goat as a live incubator for the maturation of bovine oocytes. We conclude that bovine oocytes can progress meiotically in the uterus horn of a goat and that transcervical transfer of bovine oocytes to a goat?s uterus could present an alternative to nuclear maturation

Montagem de ambiente para classificação de solos usando ScikitLearn.

Resumo - Técnicas de Mineração de Dados e Modelagem preditiva são cada vez mais usadas para automação de tarefas nos mais diversos campos do conhecimento. O da agricultura é um deles, existindo diversos modelos para predição de eventos climáticos, ocorrências de pragas e produtividade. A classificação de solos é uma das tarefas dentro dessa área que ainda não possui um sistema computacional satisfatório. Este trabalho tem como objetivo a criação de um sistema para a classificação automática de solos, a partir de dados previamente classificados segundo o método descrito no Sistema Brasileiro de Classificação de Solos (SiBCS). A modelagem para o sistema de classificação aqui proposto tem como base algoritmos de Aprendizado de Máquina. O trabalho ainda está em andamento e os resultados obtidos até agora indicam que a abordagem é promissora.Editores técnicos: Carla Geovana do Nascimento Macário, Carla Cristiane Osawa, Flávia Bussaglia Fiorini, Maria Fernanda Moura, Poliana Fernanda Giachetto

Goat incubator: the doe as a life incubator of bovine oocytes - first step.

Despite significant improvements in the in vitro production of cattle embryos, the suboptimal in vitro culture environment still limits the embryo quality and production. Techniques that associate the advantages of in vivo and in vitro systems, such as intrafollicular transfer of immature oocytes, have been proposed mainly to increase the embryo quality. In this context, we tried to use a goat as live incubator and associated nonsurgical embryo transfer techniques in small ruminants to perform ex situ (in vivo) maturation of bovine oocytes. For this, immature bovine cumulus-oocyte complexes (COCs) of grade 1 and 2 were randomly distributed into two groups for in vitro (IVM; n = 38) and ex situ (ESM; n = 40) maturation. The IVM was performed for a period of 24 h in TCM-199 medium (Gibco Life Technologies, Inc., Grand Island, NY, USA) supplemented with 20 mg/mL of FSH (Pluset, Calier, Barcelona, Spain), 0.36 mM sodium pyruvate (Sigma Chemical, St. Louis, MO, USA), 10 mM sodium bicarbonate (Sigma Chemical, St. Louis, MO, USA) and 50 mg/mL streptomycin/penicillin (Sigma Chemical, St. Louis, MO, USA) at 38.8 ºC in an atmosphere of 5% CO2 in air with maximum humidity. For ESM, a pre-synchronized nulliparous goat (12 months old) received 40 immature COCs in the uterine horn apice by transcervical route (Fonseca et al., 2014 Arq. Bras. Med.vet. Zootec) and 24 h after the procedure the structures were retrieved by the uterine flushing (Fonseca et al., 2013 Small Rumin Res). For analysis of the nuclear maturation rate and lipid quantification, the oocytes were denuded (0.1% hyaluronidase), fixed (4% paraformaldehyde) and stained with 10 ?g/mL Hoechst 33342 and 10 ?g/mL Nile Red (Molecular Probes, Inc., Eugene, OR, USA) dissolved in physiological saline (0.9% NaCl) with 1mg/mL polyvinylpyrrolidone. Oocytes displaying metaphase II plate were considered matured. The lipid amount was inferred by measuring the fluorescence intensity using the ImageJ program and fluorescence intensity were compared by Student's t-test. Forty-seven percent of the structures were recovered after uterine flushing (19/40). The nuclear maturation rate was 94.5% (18/19) and 81.6% (31/38) for ESM and IVM groups, respectively. In vitro-matured oocytes contained more lipid droplets, expressed as a higher (p < 0.05) amount of emitted fluorescence light (858 ± 73 arbitrary fluorescence units) than ex situ-matured oocytes (550 ± 64 arbitrary fluorescence units). This is the first report associating nonsurgical embryo transfer techniques with goat as live incubator for maturation of bovine oocytes. We conclude that transcervical transfer of bovine oocytes to uterine goat may be an alternative to in vitro maturation aiming the reduction of lipids without compromising nuclear maturation. Further studies are required to improve the oocyte recovery rate.Proceedings of the 31st Annual Meeting of the Brazilian Embryo Technology Society (SBTE); Cabo de Santo Agostinho, PE, Brazil, August 17th to 19th, 2017.
