Estudio sobre la viabilidad de la implementación del jurado de conciencia en el ordenamiento colombiano

El objeto del presente trabajo final de grado es analizar la viabilidad de la implementación de la figura del jurado de conciencia en el sistema penal colombiano, que fue suprimida mediante el Decreto 1861 de 1989. A su vez, hacer un análisis de derecho comparado con el fin de determinar los aspectos positivos y negativos de la implementación de los jurados en otros sistemas jurídicos. El resultado del análisis propuesto pretende determinar si es procedente la implementación de los jurados de conciencia en Colombia.

PROCESOS HIDRODINÁMICOS DE SEDIMENTACIÓN EN SISTEMAS LAGUNARES CONTINENTALES EN LA ZONA NORTE DE COSTA RICA

La Escuela de Geografía, ha elaborado una serie de valoraciones ambientales que han permitido determinar el nivel de degradación que presentan diferentes sistemas lagunares continentales, como el sistema lagunar de Caño Negro y el sistema lagunar Las Camelias, en la zona norte de nuestro país (Figura 1). Tomando como criterio de evaluación, el análisis del proceso de sedimentación y su mapeo, se pudo realizar una cartografía que generó algunos lineamientos tendientes a la restauración de los espacios, sin perder la perspectiva del medio socioambiental.Desde esta concepción geográfica, se indicaron los atributos naturales de las cuencas de estudio, que permitieron orientar la interpretación del análisis del proceso de intervención, con respecto al cambio en el uso de la tierra. Se identificó la degradación a partir de la identificación de la tasas de sedimentación, que se manifiestan en las áreas depresivas de los sistemas lagunares asociado a la hidrodinámica de los ríos.El esquema metodológico de este estudio se ajustó a un abordaje en terreno que permitió obtener información primaria y que fue procesada en el Laboratorio de Geomorfología de la Escuela de Geografía, generando un conjunto de insumos cartográficos afines a la valoración llevada a cabo.La caracterizaciones, tipos y localizaciones de la sedimentación se llevó a cabo mediante la ubicación de dispositivos anuales (controles fijos) que permitieron además, un monitoreo exhaustivo llevado a cabo durante un ciclo hidrológico. Los productos cartográficos incluyen mapas de subunidades espaciales que localizan y caracterizan la sedimentación y su fluctuación en el entorno del área depresiva y los espejos de agua.De las investigaciones finalmente se logran describir espacios ecológicamente empobrecidos, que deberían ser sometidos a un proceso restaurador y, a su vez, rehabilitados, para garantizar la estabilidad de este tipo de ecosistemas tropicales y propiciar así una mejor calidad de vida para las personas que dependen de los mismos.

A moradia estudantil universitária como tema na produção científica nacional

This study analyses the national scientific production about college students' residence halls. The country's main data bases and electronic sites of several Brazilian higher education institutions were checked and 23 studies, published between 2000 and 2009, were found. The results of our analysis point to different focuses, which can be grouped into three categories: students who live in residence halls, residence halls themselves and actions for student assistance. Although there is large foreign scientific production about college student housing, the national production on this theme is still scarce, and the idea of student residence halls as educational spaces is still very incipient. The study points out to the need for investigating the living conditions in these places, and the impacts of this kind of habitation on students. Considering that student housing is an institutional responsibility, these studies potentially subsidize measures for proper educational conditions for college students.

Sibilância em crianças e adolescentes vizinhos a uma indústria petroquímica no Rio Grande do Norte, Brasil

OBJETIVO: Verificar a associação entre relato de sibilância em crianças e adolescentes e o local de residência em relação à dispersão dos poluentes atmosféricos emitidos pelo Pólo Petroquímico (PPQ) de Guamaré (RN). MÉTODOS: Estudo transversal de relato de sibilância em crianças e adolescentes de 0 a 14 anos de idade, residentes no entorno do PPQ de Guamaré, em 2006. Foi utilizado o questionário padronizado do International Study of Asthma and Allergies in Childhood, acrescido de questões relativas ao tabagismo, renda, moradia e escolaridade. Concentrações diárias de PM10, PM2,5, carbono grafítico, SO2, NO2, O3, benzeno, tolueno e xilenos foram medidas em uma estação de monitoramento fixa. As comunidades residentes na área de influência das emissões do PPQ foram classificadas, segundo a direção preferencial dos ventos, em expostas e de referência. RESULTADOS: Participaram do estudo 209 crianças e adolescentes. As concentrações médias diárias dos poluentes monitorados mantiveram-se abaixo dos limites estabelecidos nos padrões de qualidade do ar. A prevalência de sibilos nos últimos 12 meses foi de 27,3%. Associações estatisticamente significantes com sibilos nos últimos 12 meses foram verificadas mesmo após ajustamentos para comunidades expostas [razão de chances (odds ratio, ORajust) = 2,01; intervalo de confiança de 95% (IC95%) 1,01-4,01], gênero masculino (ORajust = 2,50; IC95% 1,21-5,18) e idade de 0 a 6 anos (ORajust = 5,00; IC95% 2,41-10,39). CONCLUSÃO: Mesmo em baixas concentrações de poluentes atmosféricos, a ocorrência de sintomas respiratórios em crianças e adolescentes nas comunidades no entorno de um PPQ esteve associada a residência na direção preferencial dos ventos, mostrando-se mais vulnerável o grupo de pré-escolares do gênero masculino.

Morphological analysis of three populations of Anopheles (Nyssorhynchus) nuneztovari Gabaldón (Diptera: Culicidae) from Colombia

Based on the results of comparative analyses of 1,039 specimens of several progenies of Anopheles nuneztovarifrom three localities in Colombia, eight costal wing spot patterns were observed. Patterns I and III were the most frequent: 77.96% and 11.36%, respectively. Using the diagnostic characters ratio of the length of the basal dark area of hind tarsomere II/length of hind tarsomere II, ratio of the length of the humeral pale spot/length of the pre-humeral dark spot, and the ratio of the length of the subcostal pale spot/length of the distal sector dark spot (DS-III2/Ta-III2, HP/PHD, SCP/DSD) approximately 5% of the adult females were misidentified as a species of Nyssorhynchus, different from An. nuneztovari. Approximately 5% of the specimens showed DS-III2/Ta-III2 ratio less than 0.25 (range 0.21 - 0.24), and among them 3.34% shared a HP/PHD ratio less than 1.50. Consequently, 1.52% of An. nuneztovari individuals can be misidentified as Anopheles oswaldoi. In those specimens with the DS-III2/Ta-III2 ratios higher than 0.25, 34.45% displayed SCP/DSD values greater than 0.50 and of these, 3.65% displayed HP/PHD values greater than 1.8. This combination of characters could lead one to misidentify samples of An. nuneztovari as Anopheles rangeli. Similarly, 2.43% of the females could be identified erroneously as either Anopheles aquasalis or Anopheles benarrochi. Individuals with a HP/PHD ratio greater than 2.0, could be misidentified as Anopheles trinkae, Anopheles strodei or Anopheles evansae. A distinct combination of diagnostic characters for An. nuneztovari from Colombia is proposed.

Leishmaniose tegumentar americana no Litoral Norte Paulista, período 1993 a 2005

A leishmaniose tegumentar americana adquiriu caráter epidêmico no Litoral Norte Paulista, desde a década de 1990. A partir de dados secundários, realizou-se estudo descritivo da doença no período de 1993 a 2005 nos quatro municípios que compõem a região e analisou-se a freqüência dos flebotomíneos capturados nos locais prováveis de transmissão. Foram notificados 689 casos autóctones de leishmaniose tegumentar, com casos isolados e agrupados, determinando uma distribuição espacial heterogênea, com sincronismo na manifestação e ciclicidade, em intervalo de seis a oito anos. Todas as faixas etárias foram acometidas, com ligeiro predomínio do sexo masculino, sem associação com uma ocupação. Capturou-se 2.758 flebotomíneos e a espécie Nyssomyia intermedia predominou (80,4%), no peri e intradomicílio. A doença apresentou perfil de transmissão peri e intradomiciliar, entre o periurbano e a mata, e no interior da mata. Neste caso, a transmissão estaria mais relacionada com os focos enzoóticos.

Anticorpos anti-rickettsias do grupo da febre maculosa em equídeos e caninos no norte do Estado do Paraná, Brasil

The Brazilian Spotted Fever (BSF) is a zoonosis that can be fatal if not trteated. As there are few studies of the BSF in the Paraná State, the occurrence of BSF was serologically investigated in dogs and horses by indirect immunofluorescence assay (IFA), in the North of that State, in animals that are regarded as sentinels for BSF. A total of 241 samples of sera of equine, four of asinine, and 29 of dogs were collected in nine farms of three municipalities in the North of Paraná: Arapongas, Douradina, and Umuarama. From fifteen samples of equine serum with positive titres for RIFI, eight (53.3 %) had titre of 64 against R. rickettsii, two (13.3 %) 128 against R. rickettsii, and five (33.3 %) were reactants for R. parkeri and R. rickettsii, with titres ranging from 64 to 2048, and 128 to 1024, respectively. The results showed that domestic animals, sentinels for BSF, are under low exposition to ticks infected with spotted fever group Rickettsia, indicating low risk of human infection by these agents in the studied area.

New Genotype of Dengue Type 3 Virus Circulating in Brazil and Colombia Showed a Close Relationship to Old Asian Viruses

Dengue type 3 genotype V viruses have been recently detected in Brazil and Colombia. In this study, we described another Brazilian isolate belonging to this genotype. Phylogenetic analysis including dengue type 3 viruses isolated worldwide showed that Brazilian and Colombian viruses were closely related to viruses isolated in Asia more than two decades ago. The characteristic evolutionary pattern of dengue type 3 virus cannot explain the close similarity of new circulating viruses with old viruses. Further studies are needed to confirm the origin of the new dengue type III genotype circulating in Brazil and Colombia.

Serological Survey for Antibodies to Encephalitozoon cuniculi in Ownerless Dogs From Urban Areas of Brazil and Colombia

There are 3 strains of Encephalitozoon cuniculi that occur in mammals. Strain III is associated with clinical disease in dogs, although some can be asymptomatic carriers and excrete spores in their urine. Several cases of human E. cuniculi infection caused by strain III have been observed in immunocompromised patients, indicating that E. cuniculi should be considered a zoonotic agent. Encephalitozoon cuniculi can cause fatal disease in maternally-infected or young dogs. Clinical signs in these animals included blindness, encephalitis, retarded growth rate, and nephritis. Encephalitozoon cuniculi has also been associated with primary renal failure in adult dogs. The present study used the direct agglutination test (DAT, cut-off 1:50) and the indirect fluorescent antibody test (IFAT, cut-off 1:10) to examine the prevalence of antibodies to E. cuniculi in dogs from Brazil and Colombia. Using the DAG, 31 (27.4%) of 113 dogs from Brazil and 47 (18.5%) of 254 dogs from Colombia were seropositive. Nine (14.3%) of 63 dogs from Brazil and IS (35.3%) of the 51 dogs from Colombia were seropositive by indirect immunofluorescent antibody test. These results indicate that dogs from Brazil and Colombia are exposed to E. cuniculi.

Croton rufolepidotus (Euphorbiaceae s. str.), a New Species from Antioquia, Colombia

Crown rufolepidotus Caruzo & Riina (Euphorbiaceae s. str.), a new species from Colombia, is here described and illustrated. The new species is endemic to an area of lowland secondary forests in Antioquia. Morphological characters indicate that this species belongs to Croton sect. Cleodora (Klotzsch) Baill. due to its arborescent habit, petiolar glands, 15 to 25 stamens, as well as the pistillate flowers with imbricate sepals and multifid styles.

3-Nitrophenol-4,4 '-bipyridyl N,N '-dioxide (2/1): a DFT study and CSD analysis of DPNO molecular complexes

The title 2:1 complex of 3-nitrophenol (MNP) and 4,4'-bipyridyl N, N'-dioxide (DPNO), 2C(6)H(5)NO(3)center dot C(10)H(8)N(2)O(2) or 2MNP center dot DPNO, crystallizes as a centrosymmetric three-component adduct with a dihedral angle of 59.40 (8)degrees between the planes of the benzene rings of MNP and DPNO (the DPNO moiety lies across a crystallographic inversion centre located at the mid-point of the C-C bond linking its aromatic rings). The complex owes its formation to O-H center dot center dot center dot O hydrogen bonds [O center dot center dot center dot O = 2.605 (3) angstrom]. Molecules are linked by intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N interactions forming R(2)(1) (6) and R(2)(2) (10) rings, and R(6)(6) (34) and R(4)(4) (26) macro-rings, all of which are aligned along the [(1) over bar 01] direction, and R(2)(2) (10) and R(2)(1) (7) rings aligned along the [010] direction. The combination of chains of rings along the [(1) over bar 01] and [010] directions generates the three-dimensional structure. A total of 27 systems containing the DNPO molecule and forming molecular complexes of an organic nature were analysed and compared with the structural characteristics of the dioxide reported here. The N-O distance [1.325 (2) angstrom] depends not only on the interactions involving the O atom at the N-O group, but also on the structural ordering and additional three-dimensional interactions in the crystal structure. A density functional theory (DFT) optimized structure at the B3LYP/6-311G(d,p) level is compared with the molecular structure in the solid state.
