Abstract: Se llevó a cabo un estudio en todo el estado de Jigawa en la república de Nigeria durante noviembre-diciembre, parte de la estación de seca; donde la malaria es una de las principales causas de morbilidad y mortalidad, especialmente entre los ni os menores de 5 a os y las mujeres embarazadas. Este estado presenta 2 estaciones climáticas una seca de octubre a mayo y otra de lluvia de junio a septiembre. Se muestreó un total de 112 cuerpos de agua, solo 18 en 9 gobiernos locales resultaron positivos a mosquitos. Los sitios de cría identificados para Anopheles correspondieron a campos de arroz, peque o hueco en la tierra, pisadas de animales, peque os estanques, terrenos con pasto inundados y presa de tratamiento de agua, para un total de 10. Contrario a lo que siempre se ha reportado sobre la presencia de Anopheles en aguas limpias, se encontraron criando en aguas con alta polución que contenían heces fecales humanas y desperdicios de basura, representadas por alcantarillas abiertas en las localidades. A study was conducted in the state of Jigawa, Republic of Nigeria, from November to December in the dry season, where malaria is one of the main morbidity and mortality causes particularly in under 5 years-old children and pregnant women. This state had two climate seasons: dry from October to May and rainy from June to September. A total of 112 water bodies were sampled and just 18 in nine local governments were positive to mosquitoes. Breeding sites for Anopheles were rice fields, small holes in land, animal footsteps, small ponds, flooded pasture fields and water treatment dam, among others, to amount to 10 sites. Contrary to what has always been reported about the presence of Anopheles in clean waters, they were also breeding in highly polluted waters containing human faeces and garbage and located in open sewers. Key words: Breeding sites, Anopheles, malaria, Nigeria.

Spectrophotometric Characterization of the Complex Generated in Solution for the Reaction of H[Ru(III)Cl2(H2EDTA)] Complex with AETS Modifier Agent  [PDF]
Angélica M. Lazarin, Rosana Lázara Sernaglia
Open Journal of Synthesis Theory and Applications (OJSTA) , 2014, DOI: 10.4236/ojsta.2014.34006
Abstract: Spectrophotometric method was used to evaluate the kinetic of the complex formation from the reaction between H[Ru(III)Cl2(H2EDTA)] and the modifier agent [3-(2-aminoethyl)aminopropyl] trimethoxysilane (AEATS) (μ = 0.50 mol.dm-3 with NaCF3COO, 298.15 K), in pseudo-first order conditions. These studies showed that the reactions are successives producing several species influenced by the concentrations ratio. The electronics spectrum of all solutions showed a band in 457 nm with variable molar absorptivity (ε).

Abstract: Introducción El Centro de Rehabilitación Integral Pediátrico "Senén Casas Regueiro" fue creado en el a o 1999, en respuesta al reclamo de las familias con ni os con discapacidades físico-motoras, residentes en el municipio Habana Vieja, de contar con un sitio, cercano al domicilio, donde estos pudieran realizar el tratamiento de rehabilitación que requieren. Objetivos Conocer la percepción que las familias de los pacientes y los trabajadores tienen de la gestión del Centro. Métodos El universo estuvo constituido por los trabajadores, los ni os matriculados en el Centro, y sus familias. Se determinaron las características de salud de los ni os comparando la situación al momento del ingreso al Centro y la actual, se hizo un estudio de diagnóstico del clima laboral con el 100% de los trabajadores y se aplicaron entrevistas estructuradas para conocer la repercusión que, según percepción familiar, ha tenido para los ni os y sus familias, su incorporación al Centro. Resultados Las percepciones de los trabajadores y las de las familias acerca del Centro fueron coherentes entre sí, y ambas se correspondieron con la valoración de la evolución clínica de los pacientes realizada por los especialistas. Conclusiones Se demuestra que el Centro ha producido un impacto positivo en lo social, económico y sanitario en las familias objetos de su trabajo y por tanto, en la comunidad.

Nodulation, arbuscular mycorrhizal colonization and growth of some legumes native from Brazil
Patreze, Camila M.;Cordeiro, Lázara;
Acta Botanica Brasilica , 2005, DOI: 10.1590/S0102-33062005000300014
Abstract: the effects of rhizobial and mycorrhizal inoculation, nitrogen and phosphorus fertilization on nodulation, mycorrhizal colonization and initial growth were examined in brazilian native plants, enterolobium contortisiliquum (vell. conc.) morong, inga laurina (sw.) willd., lonchocarpus muehlbergianus hassl and platypodium elegans vogel. the experiment was carried out in a glasshouse using plastic bags filled with a mixture of sandy soil from riparian forest and vermiculite (2:1) amended with basal nutrients including np, p and n and infected with rhizobia (r), mycorrhiza (m) or both (rm), amounting seven treatments: np, p, p+r, p+rm, n, n+m and n+rm, with ten replications each. the plants were analyzed at 120 and 255 days after sowing. p deficiency negatively affected growth and nodulation of all species. autochton arbuscular mycorrhizal fungi (amf) colonized host roots and fungal inoculations did not enhance mycorrhizal colonization, which was also favored by added p. nodulation was relatively higher in e. contortisiliquum and l. muehlbergianus, mainly in treatments containing p, and with rhizobial inoculation (p+r). plants from these treatments developed better than others and, despite the rhizobia inoculated had no synergistic relationship with inoculated amf, they also showed the best percentages of mycorrhizal colonization. moreover, these two species showed highest rates of acetylene reduction and highest leghemoglobin content. these results suggest that e. contortisiliquum and l. muehlbergianus can have advantages for establishment in soils with low nitrogen levels.

Balduino,Maria Aparecida; Lessa,Zenaide Lázara;
Revista de Saúde Pública , 1986, DOI: 10.1590/S0034-89101986000100005
Abstract: a means of measurement, the application of which is similar to that of the first stages of the thurstone scale, using the method of apparently equal intervals and based on stephenson's q-technique, was elaborated, by using this tool it was planned to carry out a study on the function perception of the public health educator on the health team. the study comprises two phases: the first dealing with the construction of the instrument it self and the second with the making of a research survey, using the same. it is described every step of the first phase which consists of: gathering of information on the function assigned to the public health educator; list of the functions; turning them into statements transcribed into cards; selection of a sample of 70 cards, by a highly specialized board of judges; tabulation of the data obtained and definition of the definitive instrument. to fulfil the requisites of validity the scaling distribution should present a certain balance among the pertinent, intermediate, and non-pertinent statements. for statistical convenience and to guarantee such a balance each judge is told to place varying numbers of cards on several piles, turning its totality into a continuum approaching a normal or nearly normal distribution. such a balance has been attained and a distribution of the frequency statements sampled by the judges has shown an excellent internal agreement which qualifies this study as satisfactory. the statements have been proved to be definitive components of the measuring tool - percep??o da fun??o do educador na saúde pública (perception of the function of the educator in public health).
