Múltiplas Camadas das Relações Internacionais entre a Diplomacia e a Paradiplomacia

Abstract: This article presents the internationalization of a country taking for granted the identification of multiple layers of development of international relations processed through diplomatic and paradiplomatic actions. This piece of writing considers the characterization of a multiplicity of decentralized and parallel actions in comparison to the political agenda of the foreign ministries that also have been embodied by the consolidation of new profiles of diplomacy. Throughout this discussion subsidies are provided in order to have an apprehension about the diplomatic and paradiplomatic actions with reference to the impact on the foreign policy lato sensu.

Anestesia total intravenosa com propofol associado ao fentanil, lidocaínaou cetamina em cadelas submetidas à ovariossalpingohisterectomia eletiva

Abstract: Background: Total intravenous anesthesia with propofol is an alternative to inhalation anesthesia because it offers smoother anesthetic recovery, however, since propofol does not have adequate analgesic action, it is necessary to associate it with some drug to avoid the pain process. In addition, the combination may minimize cardiovascular depression resulting from continuous infusion of propofol by reducing infusion rate. The aim of this study was to evaluate cardiorespiratory parameters and anesthetic recovery in bitches submitted to continuous infusion of fentanyl, lidocaine and ketamine associated with total intravenous anesthesia with propofol and submitted to elective ovariohisterectomy. Materials, Methods & Results: Twenty-four bitches were medicated intramuscularly with 0.03 mg/kg of acepromazine. After 30 min, they were divided into three groups with different analgesic treatments: group F (GF) received a loading dose (LD) of 0.0036 mg/kg fentanyl, followed by continuous infusion of 0.0036 mg/kg/h; group L (GL), LD of 3 mg/kg lidocaine, followed by 3 mg/kg/h and group K (GK), LD of 0.6 mg/kg ketamine, followed by 0.6 mg/kg/h. First a LD of analgesic treatment was administered, followed by induction (to the effect) and beginning of continuous infusion of the analgesic treatment and propofol. The animals were intubated with endotracheal tube of adequate size, and connected to 100% oxygen, being kept under spontaneous ventilation during the entire period of anesthetic maintenance. The infusion of propofol started at 0.34 mg/kg/min and was adjusted so as to maintain the surgical anesthesia plane of Guedel and the cardiovascular parameters within the physiological limits for the species. The cardiorespiratory parameters were measured at different moments: basal (before application of any drug) and 5, 15, 20, 30, 40, 50, 60, 70 and 80 min after induction. The surgery started 20 min after anesthetic induction and lasted 60 min. At the end of the surgery, infusions were terminated and anesthesia recovery was evaluated by measuring the extubation time, sternal decubitus, and quadrupedal position in min. A variance analysis was performed to compare means of cardiorespiratory parameters for the moments and groups followed by the Scott-knott test. Differences were considered significant when P < 0.05. The baseline parameters, age, weight and dose of propofol IC were not statistically different between groups. The infusion rate of propofol increased in all groups from M5 to M15. GF and GL presented lower values for heart rate and GK presented higher values for the same variable. Blood pressure decreased after induction and increased in M40, M50 and M60. The variables EtCo2 , PaCo2 and HCO3 increased and pH decreased showing respiratory depression in all groups. The mean time, in min, for orotracheal extubation, sternal decubitus and quadrupedal position were respectively 5 ± 3, 20 ± 6 and 39 ± 13 for GF; 6 ± 2, 23 ± 7 and 51 ± 15 for GL; 4 ± 2, 18 ± 6 and 42 ± 22 for GK and did not present statistical difference between the groups. Discussion: The combination of continuous infusion of fentanyl, lidocaine or ketamine to total intravenous anesthesia with propofol provides cardiovascular stability, but does not prevent respiratory function depression. The dose of propofol IC was the same in all groups, thus demonstrating that analgesics have the same potency in the transoperative period and justifies similar anesthetic recovery times. Thus, it can be concluded that these associations are feasible for total intravenous anesthesia provided proper monitorins for respiratory function.

Prolapso de Útero Gravídico Associado à Retroflexão de Vesícula Urinária em Cadela com TVT – Relato de Caso / Pregnant uterine prolapse associated with retroflexion of the urinary bladder in a dog with TVT - case report

Abstract: O prolapso uterino e uma emergencia devido a possibilidade de complicacoes, como o deslocamento da vesicula urinaria. Os tratamentos buscam o retorno rapido do orgao a posicao anatomica prevenindo o aparecimento de infeccoes ou a desvitalizacao do tecido. O presente trabalho objetiva relatar o caso de uma cadela prenhe com TVT, que apresentou prolapso de utero com retroflexao de bexiga. A presenca do TVT levou ao quadro de parto distocico, por infeccao do canal do parto e por barreira fisica de passagem dos fetos. O quadro de distocia levou ao prolapso e a retroflexao de vesicula urinaria. A ovariossalpingohisterectomia e um metodo eficaz no tratamento e prevencao do prolapso uterino.

Cultivation of nine varieties of watermelon under edaphoclimatic conditions of the Brazilian Savannah: Morphological variables, physicochemical characteristics and useful life of fruits

Abstract: Refrigeration is necessary to preserve the quality of watermelon fruits for longer, however, this technology is difficult to access and costly. Therefore, it is necessary to look for alternatives such as the selection of new varieties of watermelon that present good resistance to transport, superior fruit quality and high postharvest shelf life. In this context, the objective in this work was to evaluate the morphological, physicochemical and shelf life characteristics of the fruits of nine varieties of watermelon. It was conducted through a randomized complete block experimental design in a subdivided plot scheme. Nine varieties of watermelon were evaluated in the plots: Explorer, Magnum, Santa Amelia, Top Gun, Crimson Sweet, Electra, PX 397, Charleston Gray and Jubilee, and in the subplots five storage times: 0; 5; 10; 15 and 20 days. The edaphoclimatic conditions of the Amazon Savannah in Roraima, Brazil, favor the morphological, physicochemical characteristics and shelf life of the fruits of the Explore, Santa Amelia and Crimson Sweet varieties. The fruits of the watermelon varieties quickly lose their quality and are not suitable for in nature consumption after 15 days of storage at ambient temperature and relative humidity in the Amazon Savannah of Roraima, Brazil, since the content of ° Brix after this period is less than 9 °. The new studies related to the subject must consider the acceptance of the consumer market of the varieties with the greatest potential obtained.

A agroindústria canavieira paraibana: implicações da crise no emprego e na arrecadação tributária na década de 1990

Abstract: O objetivo do trabalho e identificar as implicacoes socioeconomicas da crise na agroindustria canavieira paraibana na decada de 1990. Os dados foram obtidos junto ao Instituto Brasileiro de Geografia e Estatistica, Associacao dos Plantadores de Cana-de-Acucar da Paraiba, Secretaria de Planejamento do Estado da Paraiba e Instituto de Pesquisa Economica Aplicada. Os resultados mostram que as principais consequencias da crise na agroindustria canavieira paraibana foram a queda no numero de empregos, que estimulou o exodo rural e a reducao na renda, dada pelo encerramento das atividades de seis unidades industriais. Com isso, a producao caiu e a arrecadacao tributaria do Estado apresentou uma diminuicao significativa, principalmente nos setores primario e secundario.
