ResumoForam realizadas cento e cinqüenta necropsias em cinco espécies de peixes teleósteos de origem marinha comercializados no Mercado São Pedro, Município de Niterói, Rio de Janeiro. Utilizaram-se trinta exemplares para cada espécie de Pagrus pagrus, Pomatomus saltator, Priacanthus arenatus, Cynoscion sp. e Caranx latus, com o objetivo de verificar a prevalência e intensidade média de infecção de parasitas da ordem Trypanorhyncha. Com o auxílio de estereomicroscópio, os plerocercos foram liberados por meio de estiletes, colocados em placas de Petri com água e levados ao refrigerador por 24 horas. Após este tempo, foram processados segundo a técnica descrita por Amato et al. (1990) e identificados segundo Beveridge e Campbell (1994). As espécies Pagrus pagrus e Priacanthus arenatus estavam negativas para parasitas da ordem Trypanorhyncha. No gênero Cynoscion sp. foram observadas prevalência de 16,67% e média de intensidade de infecção de 0,17 parasitas por hospedeiro para Pterobotrium crassicolle. Em Caranx latus e Pomatomus saltator verificaram-se prevalência e intensidade média de infecção para Callitetrarhynchus gracilis de 33,33% e 0,57 parasitas por hospedeiro e, de 36,67% e 0,60 parasitos por hospedeiro, respectivamente, sendo encontrado em P. saltator para C. speciosus prevalência de 3,33% e intensidade média de infecção de 0,03 parasitas por peixe. Os inspetores de pescado devem estar atentos à presença destes parasitas em peixes marinhos, pelo aspecto repugnante que transferem ao produto.Palavras-chave:Trypanorhyncha, parasitas, peixes. AbstractA hundred and fifty necropsies have been done in five species in teleostean fishes in marine fishes commercialized in Niterói, Rio de Janeiro State. Were utilized thirty fishes for each species of Pagrus pagrus, Pomatomus saltator, Priacanthus arenatus, Cynoscion sp. and Caranx latus, with the objective of verifying the prevalence and the medium intensity infection of parasites from Trypanorhyncha order. The plerocercus were set free thru stiletto and set in Petri plate with water being kept under refrigeration per 24 hours. After this period, were processed following Amato's et al (1990) technics and identified following Beveridge and Campbell (1994). In Pagrus pagrus and Priacanthus arenatus were negatives for parasites from Trypanorhyncha order. In Cynoscion sp were found prevalence of 16,67% and medium infection intensity of 0,17 parasites per host for Pterobotrium crassicolle while in Caranx latus and Pomatomus saltator were found prevalence and medium infection intensity for Callitetrarhynchus gracilis of 33,33% and 0,57 parasites per host, as well, 36,67% and 0,60 parasites per host, respectively, being found in P. saltator for C. speciosus prevalence of 3,33% and medium infection intensity of 0,03 parasites per host. Fish sanitary inspectors must be aware of the presence of parasites from Trypanorhyncha order in marine fishes by the repugnant aspect that they transfer to the products.Keywords: Trypanorhyncha, parasites, fishes.

Resumo-Neste artigoé proposto um algoritmo de alocação de blocos de recurso para sistemas de comunicação LTE (Long Term Evolution) que considera o limitante de retardo estimado através de Cálculo de Rede utilizando curva de serviço e processo envelope MFBAP (Multifractal Bounded Arrival Process) para decidir sobre a alocação de recursos de rádio disponíveis. São realizadas comparações com outros algoritmos de alocação através de parâmetros de QoS (Quality of Service) como retardo médio, vazão total, tempo de processamento, taxa de perda é ındice de justiça (fairness), comprovando a eficiência do algoritmo proposto.Palavras-Chave-LTE, Escalonamento, Retardo, Cálculo de Rede.Abstract-In this paper it is proposed an algorithm to allocate resource blocks for LTE (Long Term Evolution) communication systems which considers the delay target estimated through Network Calculus using service curve and MFBAP (Multifractal Bounded Arrival Process) envelope process in order to decide on the scheduling of available radio resources. Comparisons with other allocation algorithms are carried out through QoS (Quality of Service) parameters such as average delay, total throughput, processing time, loss rate and fairness index, proving the efficiency of the proposed algorithm.
Brazil is the third largest producer and the main exporter of chicken meat in the world. In 2019, it produced approximately 13.245 million tons of the product, generating more than six million dollars. According to the Poultry Association of the state of Espírito Santo, broiler production is carried out by 28 independent producers/companies, three integrator businesses, 42 integrated producers and seven slaughterhouses (structures with SIF, SIE/SISBI or SIE certification). Despite the growth of this sector, problems persist regarding the quality of carcasses and the number of condemnations. From the sanitary and industrial point of view, all products of animal origin must undergo prior inspection. The present study was developed using data generated by the Federal Inspection Service (Serviço de Inspeção Federal, SIF) and the State Inspection Service (Serviço de Inspeção Estadual, SIE). The main causes of condemnation of birds as inspected by SIF represented 9.26% of the slaughtered birds. Total condemnations corresponded to 1.35%. Overall, this study recorded a greater number of condemnations of non-pathological origin. In conclusion, there was consistency in the reasons why these products were condemned. Bruises/fractures and contamination were the most frequent causes according to both inspection services (SIF and SIE), indicating a common problem on the slaughter and inspection lines.
