3. Technical efficiency analysis of marine shrimp farming (Litopenaeus vannamei) in biofloc and conventional systems: A case study in northeastern Brazil
Abstract Shrimp farming has a great ecological, economic, and social importance in northeastern Brazil. Although the conventional farming system is widely used, biofloc technology (BFT) system has been developed to reduce environmental impacts and optimizing the production. Thus,the present study evaluated the technical efficiency of production cycles of Lit

8. Long-term planning of a container terminal under demand uncertainty and economies of scale
Governments of many developing countries are presently granting concessions to private organizations to operate container terminals. A key element in this process is the technical and economic evaluation of the project. In practice, the demand levels over time are volatile. The first part of the paper deals with a capacity expansion problem with stochastic d

12. Efeito in vitro da incorporação de colesterol à membrana plasmática de espermatozoides criopreservados de jumentos (Equus asinus) da raça pêga / In vitro effect of plasma membrane cholesterol incorporation to pêga donkey (Equus asinus) cryopreserved spermatozoa
A criopreservação de sêmen asinino vem apresentando limitações na fertilidade que desestimulam sua utilização como rotina para profissionais que trabalham com a espécie. A incorporação de colesterol associado à ciclodextrina (CLC) tem se mostrado uma alternativa promissora por melhorar a resistência espermática ao processo de criopreservação e
