Histological effect caused by contrast solution injection for post mortem compu...
Ferrante, B.; Baroni, C. O.; Muramoto, C.; Ribas, L. M.M. [UNESP]; Torres, L.; Catão-Dias, J. L.; Pinto, A. C.B.C.F.Made available in DSpace on 2022-04-29T08:29:21Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-03-01; The post mortem computed tomography angiography (PMCTA) is a technique that uses a contrast solution to evaluate the vascular structures in cadavers. This study aims to verify if there is any tissue impairment in parenchymatous organs after PMCTA in dogs. PMCTA was performed in 9 cadavers, divided into ...
Risk assessment for tomato fruitworm in processing tomato crop-egg location and...
Figueiredo, E.; Gonçalves, C.; Duarte, S.; Godinho, Maria; Mexia, A.; Torres, L.The tomato fruitworm, Helicoverpa armigera, is a key pest of several crops. It can cause particularly extensive damage in crops of processing tomatoes. Risk assessment can be a tedious and costly task if sampling protocols require a large number of plants. Sequential sampling allows sampling of a reduced number of plants when population densities are much lower or much higher than the economic or control thresh...
Lettuce growth and nutrient uptake response to winery waste compost and biochar
Pinto, Rui; Brito, Luis Miguel; Gonçalves, F.; Mourão, Isabel de Maria; Torres, L.; Coutinho, J.The composting process of winery wastewater sludge with grape stalks enables these wastes to be recycled as soil organic amendments or pot substrate components. However, it is necessary to assess the potential of this compost as crop fertilizer. This assessment is also needed for the use of biochar as soil amendment because negative effects on crop growth and nutrient uptake may occur depending on application r...
DNA screening of Drosophila suzukii predators in berry field orchards shows new...
Sario, Sara; Santos, Conceição; Gonçalves, Maria de Fátima; Torres, L.Drosophila suzukii (spotted wing drosophila, SWD) is a pandemic quarantine pest that attacks mostly red fruits. The high number of life cycles per year, its ability to rapidly invade and spread across new habitats, and highly polyphagous nature, makes this a particularly aggressive invasive species, for which efficient control methods are currently lacking. The use of native natural predators is particularly pr...
Bond behavior of NSM CFRP laminates in concrete under sustained loading
Emara, M.; Barris, C.; Baena, M.; Torres, L.; Barros, Joaquim A. O.The success of Fiber Reinforced Polymers (FRP) strengthening methodologies for reinforcing concrete structures is highly related to the interfacial bond properties between reinforcement and concrete, which depends upon a number of parameters. Several studies were carried out investigating the short-term bond behavior of Near Surface Mounted (NSM) FRP strengthening systems. However, there has been only limited i...
Effects of pollen, sugars and honeydew on lifespan and nutrient levels of Episy...
Pinheiro, Lara Alina; Torres, L.; Raimundo, João; Santos, Sónia A.P.Hoverflies require pollen, nectar and honeydew during their adult stage, but little is known about the suitability and nutrient provision of each of those resources. Thus, in this study we assessed the effect of different types of food, such as carbohydrates (glucose, fructose, sucrose and honey), pollen, a mixture of honey and pollen, and honeydew on longevity and nutrient levels of Episyrphus balteatus (De Ge...
Sirfídeos associados ao olival transmontano Importância da vegetação herbácea e...
Pinheiro, Lara Alina; Torres, L.; Santos, Sónia A.P.Os sirfídeos são insetos vulgarmente conhecidos por “moscas-das-flores” em virtude de, no estado adulto, serem frequentemente observados a pairar sobre flores. A nível mundial estão descritas nesta família mais de 6000 espécies (Bisby et al., 2012); na Europa existem atualmente 725 espécies válidas e 163 de carácter taxonomicamente incerto (Speight & Sarthou, 2011a) e em Portugal estão citadas 179 espécies (van...
Efeito da vegetação herbácea na longevidade e reservas corporais de Episyrphus ...
Pinheiro, Lara Alina; Raimundo, João; Benhadi-Marín, Jacinto; Torres, L.; Santos, Sónia A.P.As larvas dos sirfídeos são importantes predadores, especialmente, de espécies pertencentes à ordem Hemiptera. No entanto, os sirfídeos adultos alimentam‐se à base de pólen, néctar e meladas. Entre as plantas herbáceas espontâneas que habitualmente fazem parte da cobertura ou das orlas dos agroecossistemas existem várias espécies com potencial para atraírem sirfídeos e fornecerem alimento. Neste contexto é fund...
FEM-based modelling of NSM-FRP bond behaviour
Sharaky, I. A.; Barros, Joaquim A. O.; Torres, L.Bond between Fibre Reinforced Polymer (FRP) Near-Surface Mounted (NSM) reinforcement and concrete is one of the key factors affecting the behaviour of this strengthening methodology. Properties of FRP, adhesive and concrete greatly affect the effectiveness of the NSM technique. Due to the variety of factors involved in the behaviour of FRP NSM strengthening systems, mechanical models able to incorporate the inf...
Efeito na sobrevivência, crescimento e reservas corporais de Episyrphus balteat...
Pinheiro, Lara Alina; Torres, L.; Santos, Sónia A.P.A dependência dos sirfídeos adultos por pólen e néctar aumenta o potencial para o estabelecimento de flores no ecossistema olivícola e, desta forma, contribui para o incremento da luta biológica contra o algodão-da-oliveira, Euphyllura olivina Costa. A família das Asteraceae é uma das mais referenciadas em termos de preferências alimentares por parte dos sirfídeos, sendo a facilidade de acesso ao recurso floral...
