This paper deals with the application of a dynamic model, combining Transaction Cost Economics (TCE) and Penrose’s theory of the growth of firms, under the New Institutional Economics (NIE) terms, to analyze and manage the “Agribusiness Innovation System” (SIE) coordinated by an agricultural research-development (R&D) organization in Brazil – Embrapa....
The aim of this paper is to propose a model to analyze and manage the scientific-technological innovation systems in public organizations dedicated to R&D in agribusiness, such Embrapa, under the terms of the theoretical system supplied by the New Institutional Economics. The purpose is to identify parameters that can increase...

This thesis describes a control tool for managers of a
Broiler Breeder Farm, a farm which raises chickens for the purpose
of fertile egg production. It presents the development of
a simulation of a Broiler Breeder Farm which uses a deterministic
step by step process to generate expected values of...
This research focuses on biochemical changes related to quality losses observed in Atlantic mackerel (Scomber scombrus) muscle stored under commercial frozen storage conditions (9 months, -18 ºC) when subjected to high-hydrostatic pressure (HHP) treatments (125, 150, 175 and 200 MPa for 0 min) before freezing. After freezing, free fatty acid...
Mycobacterium avium subspecies hominissuis (M. avium) is a ubiquitous, acid-fast organism found in water and soil. This opportunistic pathogen is a common causative of pulmonary diseases in immunocompromised individuals and prevalent infection in HIV/AIDS patients. As a primary defense response against infection, immune cells such as macrophages phagocytize M. avium...
Alzheimer’s Disease (AD) is a neurodegenerative pathology currently affecting nearly 44 million individuals worldwide, yet there are not currently any effective treatments or preventions for AD despite the rapid development in our understanding of the disease over the last four decades. The medical and sanitary innovations of the last century...
