Filtration processes using fibrous filter media are very used to retain microparticles in a stream air due to its simple use, low operational cost and high collection efficiency. However, the study of submicron particles ...

Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...

The present thesis studied the hydrolysis and fermentation steps of the hydrothermally pretreated sugarcane straw (cellulosic fraction), aiming bioethanol and biobutanol production. In regards to the hydrolysis step, it ...

Soybean seed is a renewable feedstock and the production process of soybean meal and soybean refined oil generates residues that can be exploited, in such a way that the biorefinery concept can be applied to this production ...

Interest in the use of mesenchymal stromal cells (MSCs) has increased in the last 10 years because of the increasing discovery of its special characteristics for the treatment of diseases through cell therapy or tissue ...

Brazil is the second largest producer of soybean, with the projection of becoming the largest producer in 2019/2020. All Brazilian soybean oil is produced by the extraction process with hexane, an oil derivative. One way ...

Taylor-Vortex reactor (TVB) is fast becoming the next bioreactor to culture animal cells due to milder shear and homogeneous flow structures through-out the bioreactor in comparison to the traditional stirred vessels. ...

Typical hydrometallurgical processes for metal production such as zinc, copper, nickel and cobalt, among others, are carried out in huge electrochemical tankhouses since only low current densities can be applied in order ...

This work deals with modeling applications, systematic and reliable optimization methodologies of global search, and other computational tools. It is expected that existing computational intelligence methods, encoded in ...

People are increasingly wasting their time in indoors environments, in these locations there is a risk of contagion from diseases transmitted by the airways, due to low rates of air exchange. Thus, the number of causative ...
