Algoritmo de optimización mediante forrajeo de bacterias híbrido para el problema de selección de portafolios con restricción de cardinalidad
In this paper we tackle the optimal portfolio selection problem (PSP). Many research has been made around this subject mainly in two ways, whether extending the Markowitz model by taking into account real-world constraints (floor-ceiling, class and cardinality) or introducing different risk measures like semivariance, value at risk, absolute desviation, etc. Here, we present the preliminary res...
متن کاملOil adjuvant elevates protection of rainbow trout (Oncorhynchus mykiss) following injection vaccination against Yersinia ruckeri
Enteric redmouth disease (ERM) caused by the fish pathogen Yersinia ruckeri is a major threat to freshwater production of rainbow trout throughout all life stages. Injection vaccination of rainbow trout against Y. ruckeri infection has been shown to confer better protection compared to the traditionally applied immersion vaccination. It may be hypothesized, based on experience from other vaccin...
متن کاملAssociation between Plasma Antibody Response and Protection in Rainbow Trout Oncorhynchus mykiss Immersion Vaccinated against Yersinia ruckeri
A key hallmark of the vertebrate adaptive immune system is the generation of antigen-specific antibodies from B cells. Fish are the most primitive gnathostomes (jawed vertebrates) possessing an adaptive immune system. Vaccination of rainbow trout against enteric redmouth disease (ERM) by immersion in Yersinia ruckeri bacterin confers a high degree of protection to the fish. The immune mechanism...
متن کاملBiochemical and molecular heterogeneity among isolates of Yersinia ruckeri from rainbow trout (Oncorhynchus mykiss, Walbaum) in north west Germany
BACKGROUND Enteric Redmouth Disease (ERM), caused by Yersinia ruckeri, is one of the most important infectious diseases in rainbow trout (Oncorhynchus mykiss) aquaculture in Europe. More recently, non-motile vaccine resistant isolates appear to have evolved and are causing disease problems throughout Europe, including Germany. The aim of this study was to analyse the variation of biochemical an...
متن کاملDetection of Yersinia ruckeri in rainbow trout (Oncorhynchus mykiss) fry tissues, using bacterial culture, simple PCR and nested PCR
In this study the efficacy of bacterial culture, simple PCR and nested-PCR techniques for the detection of Yersinia ruckeri in tissues of naturally and experimentally infected rainbow trout (Oncorhynchus mykiss) fry was compared. In order to detect Y. ruckeri in naturally infected rainbow trout tissues, 30 fish suspected of enteric redmouth disease were randomly collected from 6 rainbow trout f...
