Brazil: an emerging military power? The problem of the use of force in Brazilian international relations in the 21st century

The central goal of this paper is thinking about the Brazilian military power and its linking to the international ambitions of the country in the 21st century. After a comparative analysis to other BRICs and with a historical one about Brazil's strategic irrelevance, we aim to establish what the minimum military capacity Brazil would need in order to meet the country's latest international interests. Similarly, it will be discussed if the National Strategy of Defense, approved in 2008, and the recent strategic agreements signed with France represent one more step toward this minimum military capacity.

An outline of military technological dynamics as restraints for acquisition, international cooperation and domestic technological development

The expectation that technological returns from defense expenditure through acquisition, international cooperation and domestic research would further national development underappreciates the different technological dynamic of the armed services. This paper outlines the technological dynamic the stems from fighting in the air, at sea and on land, exemplifying consequences for the case of acquisition.

Fatores socioeconómicos y mortalidad infantil en Ecuador, 1970-1981

En Ecuador la tasa de mortalidad infantil se redujo entre 1970 y 1981 en un 35%, a pesar de lo cual su valor sigue siendo elevado en el contexto latinoamericano. A nivel provincial, el comportamiento de la tasa no ha sido homogéneo, observándose fuertes diferencias entre las entidades en cuanto a la mortalidad durante el primer año de vida. Mediante el empleo de técnicas de regresión múltiple, pretendióse identificar aquellos factores socioeconómicos que más han incidido en el descenso de la mortalidad infantil en Ecuador en el período señalado, así como las variables que más explican las diferencias interprovinciales en dicho indicador. La disminución de la natalidad y el aumento proporcional de los gastos del presupuesto destinado a salud por una parte, y la tasa de alfabetización por otra parecen ser elementos claves para una explicación económico social de los cambios recientes en la mortalidad infantil ecuatoriana.

Adenoviruses isolated from civilian and military personnel in the city of Rio de Janeiro, Brazil

Adenovirus are important pathogen primarily associated to respiratory infections of children and military personnel, even though it is also associated to cases of conjunctivitis and keratoconjunctivitis. We analyzed respiratory secretion collected from subjects with and without respiratory infection symptoms, being 181 civilians and 221 military subjects. The samples were inoculated in HEp-2 and/or A549 tissue cultures for viral isolation. Samples presenting cytopathogenic effect (CPE) in any tissue culture were tested by a polymerase chain reaction (PCR) assay to confirm adenovirus isolation. The isolates confirmed as adenovirus were further analyzed by restriction endonuclease assay for determination of viral species. Three isolates were identified as specie A (two from civilian and one from military), one isolate from military was identified as specie C, and one isolate from civilian was identified as specie D. For two isolates the specie could not be identified.

Intestinal helminthiases in Ecuador: the relatíonship between prevalence, genetic, and socioeconomic factors

Prevalence of infection with the intestinal helminths, Ascaris lumbricoides, Trichuris trichiura, Ancylostoma duodenale and Strongyloides stercoralis was examinedin 632 residents of communities in Esmeraldas province of Ecuador. These communities were divided into two groups according to area of habitation which reflected different socioeconomic circumstances. Attempts were made to correlate infection status with race and ABO blood group phenotype. The racial groups included blacks, Chachi amerindians, and mixed-race mestizos. Greater prevalences of infection were seen in the area oflower socioeconomic status. No racial or blood group associations with helminth infection were seen controlling for socioeconomic status.

Severe digestive pathology associated with chronic Chaga's disease in Ecuador: report of two cases

DNA extracted from peripheral blood of two Ecuadorian patients showing severe digestive pathology was amplified by the polymerase chain reaction using a Trypanosoma cruzi specific oligonucleotide primers derived from the primary sequence of a cDNA encoding for a 24 kDa excretory/secretory protein. The positive PCR results together with the clinical findings confirmed that both patients had a digestive pathology due to Chagas' disease. This pathology could be more frequent than previously described in the chagasic endemic regions of Andean countries.

Control of intestinal helminths in schoolchildren in Low-Napo, Ecuador: impact of a two-year chemotherapy program

A school-based control program of intestinal helminths was undertaken among schoolchildren in the Low-Napo region, north-eastern Ecuador. Forty-eight percent of children were infected with one or more helminths at the first examination. The prevalence at the baseline was Ascaris 33.2% followed by hookworm 24.1% and Trichuris 6.5%. Sex was found to be a significant factor influencing the prevalence of hookworm and Trichuris. Prevalence was compared 9 months and 18 months after treatment. After 9 months, Ascaris and Trichuris prevalence had decreased but not hookworm. All of them increased after 18 months. The findings suggest that only a course of mebendazol had a minor effect on the control of helminth infections.

Leishmaniasis transmission: distribution and coarse-resolution ecology of two vectors and two parasites in Egypt

Introduction: In past decades, leishmaniasis burden has been low across Egypt; however, changing environment and land use has placed several parts of the country at risk. As a consequence, leishmaniasis has become a particularly difficult health problem, both for local inhabitants and for multinational military personnel. Methods: To evaluate coarse-resolution aspects of the ecology of leishmaniasis transmission, collection records for sandflies and Leishmania species were obtained from diverse sources. To characterize environmental variation across the country, we used multitemporal Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) for 2005-2011. Ecological niche models were generated using MaxEnt, and results were analyzed using background similarity tests to assess whether associations among vectors and parasites (i.e., niche similarity) can be detected across broad geographic regions. Results: We found niche similarity only between one vector species and its corresponding parasite species (i.e., Phlebotomus papatasi with Leishmania major), suggesting that geographic ranges of zoonotic cutaneous leishmaniasis and its potential vector may overlap, but under distinct environmental associations. Other associations (e.g., P. sergenti with L. major) were not supported. Mapping suitable areas for each species suggested that northeastern Egypt is particularly at risk because both parasites have potential to circulate. Conclusions: Ecological niche modeling approaches can be used as a first-pass assessment of vector-parasite interactions, offering useful insights into constraints on the geography of transmission patterns of leishmaniasis.

Dos nuevas especies del grupo Drosophila onychophora (Diptera, Drosophilidae) en los bosques de Polylepis de Papallacta, Pichincha, Ecuador

A pesar de ser un país relativamente pequeño, Ecuador tiene una gran variedad de ecosistemas que han favorecido altos niveles de especiación. Uno de estos ecosistemas es el bosque de Polylepis. En estos bosques existe una gran diversidad de plantas, como las asteráceas (compuestas), cuyas flores hospedan una plétora de insectos, entre los que se encuentran las especies del grupo Drosophila onychophora. En este estudio, describimos dos nuevas especies de Drosophila recolectadas en un parche de bosque de Polylepis pauta en el Páramo de Papallacta a 4000 msnm. Ambas especies pertenecen al grupo D. onychophora: Drosophila yurag sp. nov. y Drosophila yuragshina sp. nov. Las dos especies presentan edeagos alargados, este carácter es propio de especies del grupo. Morfológicamente ambas especies son muy parecidas, la manera más fácil de distinguirlas consiste en la observación de las alas.

Cuatro nuevas especies del grupo Drosophila onychophora (Diptera, Drosophilidae) en el Parque Arqueológico Rumipamba, Pichincha, Ecuador

Las especies de los subgéneros Phloridosa y Drosophila (este último en relación con los grupos de especies: D. flavopilosa, D. onychophora y D. bromeliae) son especies de Drosophila que se desarrollan únicamente en flores. El grupo D. onychophora fue propuestopara agrupar a especies exclusivamente antófilas. El grupo D. onychophora está integrado por 18 especies, que se encuentran relacionadas con las flores de Asteraceae. En el Parque Arqueológico Rumipamba, provincia de Pichincha, Ecuador, se realizaron capturas de Drosophila, en los meses de febrero, mayo, julio, septiembre y diciembre del 2009. Las especies fueron recolectadas directamente en las flores con un aspirador entomológico. En total se capturaron 427 individuos de Drosophila y se identificaron 11 especies, de las cuales seis son nuevas especies del grupo D. onychophora y una es un nuevo registro para el Ecuador. En este trabajo se describen cuatro de las seis especies nuevas.
