| Kelps are dominant primary producers in temperate coastal ecosystems. Large amounts of kelp biomass can be exported to the seafloor during the algal growth cycle or following storms, creating new ecological niches for the associated microbiota. Here, we investigated the bacterial community associated with the kelp Laminaria hyperborea during its accumulation and degradation on the seafloor. Kelp tissue, seawater and sediment were sampled during a six‐month in situ experiment simulating kelp detritus accumulation. Evaluation of the epiphytic bacterial community abundance, structure, taxonomic composition and predicted functional profiles evidenced a biphasic succession. Initially dominant genera (Hellea, Litorimonas, Granulosicoccus) showed a rapid and... |

| Acoustic impulse responses of young coconut fruits were analyzed using Fourier analysis and the correlation of signal characteristics with the mucous-like stage, cooked rice-like stage and leather-like stage maturity levels was determined. Analyses of sound signals of unshaved and shaved fruit samples were performed to determine if the difference in acoustic response could help enhance the differentiation of the fruits at different maturity levels. Results of statistical analysis showed that the frequency of the impulse response of the unshaved fruits increases with maturity levels and are significantly different from each other, while those of the shaved fruits are not. Also, results of regression analysis showed that as the fruits mature and the meat or... |

| A new analysis of high-resolution multibeam and seismic reflection data, collected during several oceanographic expeditions starting from 1999, allowed us to compile an updated morphotectonic map of the North Anatolian Fault below the Sea of Marmara. We reconstructed kinematics and geometries of individual fault segments, active at the time scale of 10 ka, an interval which includes several earthquake cycles, taking as stratigraphic marker the base of the latest marine transgression. Given the high deformation rates relative to sediment supply, most active tectonic structures have a morphological expression at the seafloor, even in presence of composite fault geometries and/or overprinting due to mass-wasting or turbidite deposits. In the frame of the... |

| This experiment aimed to determine the crop evapotranspiration (ETc), groundwater input in total water used by wheat crop, and to simulate the CROPWAT model to envisage the crop evapotranspiration rate. To estimate on-field ETc and groundwater contribution the combining lysimeter technique was used. The water levels below the soil surface were kept at 1.60, 2.20, and 2.80 m and each water table depth was replicated three times. The experiment was conducted under silt loam (SL) and silty-clay loam (SCL) soil conditions. The climatic parameters and water balance components were recorded accordingly. The on-field ETc was compared with the predicted ETc by CROPWAT model. Under SL soil, the observed ETc was 442, 427, and 401 mm at the water table depth of 1.60,... |

| ABSTRACT Acylated anthocyanins from a purple-fleshed sweet potato (PFSP), obtained by organic cultivation in Brazil, were characterized after separation by a high performance liquid chromatography-diode array detector (HPLC-PDA). These anthocyanins were manually collected at the detector output, concentrated and injected into a high resolution mass spectrometer (ESI-QTOF-MS2). Twenty-two acylated anthocyanins were detected. Among them, sixteen had been reported in the literature and six, derived from peonidin were reported for the first time in sweet potato roots in this study. These compounds showed molecular ions with accurate mass/charge ratios (m/z) of 909.2081, 961.3010, 961.2571, 963.3345, 1123.2932 and 1179.3862. Although anthocyanins in PFSP have... |

| Resumo ? No Distrito Federal e entorno, a produção e o consumo de mandioca de mesa são expressivos. Entretanto, em determinadas épocas do ano, as raízes da mandioca de mesa podem apresentar dificuldade para o cozimento em função de questões genéticas e ambientais. O bicarbonato de sódio tem sido apontado, de forma empírica, como alternativa de solução. Assim, avaliou-se o bicarbonato de sódio como agente de massa no cozimento de raízes de mandioca de mesa. Diferentes concentrações desse agente de massa no cozimento de raízes de mandioca das cultivares BRS 397 e BRS 399 foram estudadas. Foram avaliadas a adição do produto diretamente na água de fervura para o cozimento das raízes e no tratamento prévio ao cozimento, em que as raízes foram mantidas submersas... |

| Este estudo teve como principal objetivo caracterizar a adoção de práticas e tecnologias de agricultura de precisão por produtores de cana-de-açúcar fornecedores para indústria. Foram coletados dados primários junto a uma amostra de 131 produtores no Estado de São Paulo por meio da aplicação de questionário. Foram identificadas seis práticas de agricultura de precisão adotadas pelos produtores: sistematização de plantio com auxílio de GPS e imagens, colheita com piloto automático, análise de solo georreferenciada, levantamento de pragas e doenças utilizando imagens, aplicação de fertilizantes e corretivos a taxa variada e aplicação de defensivos a taxa variada. Produtores que adotaram, no mínimo, uma dessas seis práticas foram classificados como adotantes.... |
