Greenhouse Energy Consumption for Rose Production in Different Regions of Portu...

Baptista, F.J.; San Jose, E.; Guimaraes, A.C.; Navas, L.M.; Meneses, J.F.

In this work results of an energy consumption study for rose production in multi-tunnel greenhouses, located in Porto (Pedras Rubras), Marinha Grande, Dois Portos, Zambujeira, Faro, Funchal and Ponta Delgada, are presented. The greenhouse considered with a surface area of about 1 ha had galvanised steel structure and was covered with three layer co-extruded plastic films. It was equipped with a hot water heatin...


Greenhouse Energy Consumption for Tomato Production in the Iberian Peninsula Co...

Baptista, F.J.; Silva, A.T.; Navas, L.M.; Guimaraes, A.C.; Meneses, J.F.

Greenhouse climate models are a powerful tool which allows the simulation of inside environmental conditions as a function of external conditions, construction and environmental control equipments characteristics. They also permit to evaluate the energy consumption necessary to obtain the predefined conditions. A theoretical study of the greenhouse energy requirements for all year round tomato production in Por...


Determinação de Coeficientes de Transferência de Calor por Convecção em Estufas...

Baptista, F.J.; Navas, L.M.; Fitas da Cruz, V.; Meneses, J.F.; Relea, E.; Guimarães, A.C.

A determinação dos coeficientes de transferência de calor por convecção é complexa devido ao elevado número de factores a considerar, tais como a natureza e posição da superfície e a natureza dos fluxos de energia (natureza da convecção, natural, forçada ou mista, e do tipo de fluxo, laminar ou turbulento). A análise pode ser simplificada utilizando os números adimensionais de Grashof (Gr), Reynolds (Re), Prand...


Conventional cytogenetic characterization of a new cell line, ACP01, establishe...

Lima,E.M.; Rissino,J.D.; Harada,M.L.; Assumpção,P.P.; Demachki,S.; Guimarães,A.C.; Casartelli,C.; Smith,M.A.C.; Burbano,R.R.

Gastric cancer is the second most frequent type of neoplasia and also the second most important cause of death in the world. Virtually all the established cell lines of gastric neoplasia were developed in Asian countries, and western countries have contributed very little to this area. In the present study we describe the establishment of the cell line ACP01 and characterize it cytogenetically by means of in vi...

Western blot detection of infectious bursal disease virus infection

Pereira,S.R.F.G.; Travassos,C.E.P.F.; Huguenim,A.; Guimarães,A.C.C.; Silva,A.G.; Guimarães,M.A.A.M.

In order to evaluate the use of a Western blot methodology for the diagnosis of infectious bursal disease virus (IBDV) infection, chickens were experimentally infected with IBDV strains and tested for the presence of viral antigens and antibodies by a blocking Western blot test (bWB). The viral proteins obtained from the bursa of Fabricius (BF) were transferred to a nitrocellulose membrane after sodium dodecyl ...

Rotavirus and reovirus interaction with mouse peritoneal resident phagocytic cells

Guimarães,M.A.A.M.; Nozawa,C.M.; Guimarães,A.C.C.; Ramos,S.

Rotaviruses and reoviruses are involved in human and animal diseases. It is known that both viruses penetrate the gastrointestinal tract but their interaction with phagocytic cells is unknown. To study this interaction, peritoneal resident phagocytic cells were used and rotavirus and reovirus replication in peritoneal phagocytic cells was observed. However, rotavirus replication in these cells led to the produc...

Regional variation in toxoplasmosis seronegativity in the São Paulo metropolita...

Guimarães,A.C.S.; Kawarabayashi,M.; Borges,M.M.; Tolezano,J.E.; Andrade Jr.,H.F.

Toxoplasmosis is a highly prevalent zoonotic human infection caused by the Apicomplexa protozoon Toxoplasma gondii. The acute disease is usually mild or asymptomatic, except for foetal infection transmitted by acutely infected pregnant women, which courses as a devastating disease. In order to determine possible regional variations in risk factors, we studied the frequency of seronegativity in areas of the São ...
