Beef cattle production in established integrated systems.

The aim of the current study is to assess three integrated systems presenting different eucalyptus tree densities due to animal and forage production. The following integrated systems were assessed: croplivestock- forest with 357 eucalyptus trees ha-1 (ICLF1); crop-livestock-forest with 227 eucalyptus trees ha-1 (ICLF2); and crop-livestock with 5 remnant native trees ha-1 (ICL). The randomized block experimental design was applied in a split-plot scheme with four replicates. The Average Daily Gain (ADG, g animal-1day-1) and the live-weight gain per area (LWG, kg ha-1) were applied to analyze animal performance, which was set by weighing the animals every 28 days (the animals previously fasted for 16h). Forage yield was higher in ICL during fall and winter; in summer, it did not differ from ICLF2. There was no forage yield difference between the ICL and ICLF2 systems in any of the assessed seasons; summer was more productive in ILPF1 than other seasons. The highest leaf crude protein contents (CP) in summer was recorded in systems ICLF1 and ICLF2, and the highest value recorded in fall was found in ILPF1; the lowest was found in ILP. On the other hand, the highest leaf NDF contents in summer were found in ILP. The highest ADG were found in summer. The highest LWG values recorded for the ICL and ICLF2 systems were collected in summer and fall; there was no difference in any of the three systems in winter. The LWG was higher in all system in summer. The ICLF2 emerged as the system (with trees) most appropriate for beef cattle production. Despite the shading interference on forage production, such condition is compensated by the best nutritional contents such as CP. The ICLF2 system allowing an annual LWG of 83% in relation to the ICL system during the fifth year of establishment of the systems.Título em português: Produção de bovinos de corte em sistemas de integração estabelecidos

HPV in women assisted by the family health strategy

OBJECTIVE: Estimate the prevalence of cervical HPV infection among women assisted by the Family Health Strategy and identify the factors related to the infection. METHODS: A cross-sectional study involving 2,076 women aged 20–59 years old residing in Juiz de Fora, State of Minas Gerais, who were asked to participate in an organized screening carried out in units were the Family Health Strategy had been implemented. Participants answered the standardized questionnaire and underwent a conventional cervical cytology test and HPV test for high oncogenic risk. Estimates of HPV infection prevalence were calculated according to selected characteristics referenced in the literature and related to socioeconomic status, reproductive health and lifestyle. RESULTS: The overall prevalence of HPV infection was 12.6% (95%CI 11.16–14.05). The prevalence for the pooled primer contained 12 oncogenic HPV types (31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) was 8.6% (95%CI 7.3–9.77). In the multivariate analysis, it was observed that the following variables were significantly associated with a higher prevalence of HPV infection: marital status (single: adjusted PR = 1.40, 95%CI 1.07–1.8), alcohol consumption (any lifetime frequency: adjusted PR = 1.44, 95%CI 1.11–1.86) and number of lifetime sexual partners (≥ 3: adjusted PR = 1.35, 95%CI 1.04–1.74). CONCLUSIONS: The prevalence of HPV infection in the study population ranges from average to particularly high among young women. The prevalence of HPV16 and HPV18 infection is similar to the worldwide prevalence. Homogeneous distribution among the pooled primer types would precede the isolated infection by HPV18 in magnitude, which may be a difference greater than the one observed. The identification of high-risk oncogenic HPV prevalence may help identify women at higher risk of developing preneoplastic lesions.

Hábito de fumar en embarazadas. Hospital de Clínicas de Asunción, 1999

Los objetivos de este estudio fueron: conocer laprevalencia de fumadoras y de expuestas al humo detabaco ambiental ajeno (fumadoras pasivas) entre lasembarazadas en una institución de salud, averiguar elgrado de conocimientos referente a las implicancias deltabaco sobre la salud, evaluar las molestias en un ambientecerrado con gente fumando, conocer la existencia defamiliares fumadores; y entre las fumadoras, conocer elgrado de dependencia a la nicotina, las causas del hábito,los consejos recibidos, los intentos para dejar de fumar.Material y métodos: el diseño de estudio fue el observacional,descriptivo, transversal. Se incluyeron en esteestudio 113 embarazadas (Intervalo de Confianza (IC) del95% ), que acudieron para sus controles en la MaternidadNacional del Hospital de Clínicas de Asunción, durante elaño 1 999. El método utilizado fue el de la encuesta y lainformación fue obtenida por medio de un cuestionario.Los resultados indican un 13,3% (IC95%: 7,0 a 19,6)de fumadoras y 64,6% (IC95%: 55,8 a 73,4) de fumadoraspasivas; entre todas las embarazadas, el 58,4% (IC95%:49,4 a 67,4) conocían el texto de la ley existente, 80,5%(IC95%: 73,2 a 87,8) refirieron sentir molestias en unambiente cerrado con gente fumando, el 53,1% (IC95%:43,9 a 62,3) conocían las enfermedades principales relacionadascon el hábito de fumar, 55,0% (IC95%: 45,8 a64,2) consideraron que el tabaquismo pasivo puede afectarla salud, y el 74,3% (IC95%: 66,3 a 82,3) de los familiaresfumaban; entre las fumadoras, las pruebas de dependenciaa la nicotina registraron dos casos con puntajes de siete yocho, una con cinco y las restantes con puntajes de cero ados, seis de ellas iniciaron el hábito imitando a alguien ycuatro por curiosidad, ocho recibieron consejos para dejarde fumar y 13 intentaron dejar de fumar en promedio endos oportunidades.En conclusión se observo una prevalencia importantede fumadoras activas y pasivas, en su mayoría tuvieronconocimientos sobre las implicancias del tabaco sobre lasalud; entre las fumadoras la alta dependencia a la nicotinafue escasa, en su mayoría intentaron dejar de fumar y recibieronpocos consejos para ello del personal de salud

CORRELAÇÃO ENTRE UNIFORMIDADE E NDVI EM POVOAMENTOS DE Tectona grandis L. f.

A busca por produtos provindos de Teca é crescente, devido suas características físico-mecânicas. Seu cultivo é cada vez maior em função do valor agregado da madeira. Visando minimizar o ciclo para obtenção de seus produtos, se faz necessário métodos que permitam acompanhar e identificar a qualidade dos plantios. Com isso, o manejo florestal e o sensoriamento remoto auxiliam na seleção de instrumentos de análise para plantios comerciais. O índice de uniformidade auxilia nas tomadas de decisões na qualidade silvicultural dos plantios. Este trabalho buscou correlações entre uniformidade e NDVI para investigar o desenvolvimento da Teca. Foram utilizadas imagens do Landsat8-OLI para obtenção do NDVI e valores de reflectância da Banda 6. A cultura de Teca foi implementada no ano de 2005. Os dados de campo foram provenientes de inventários florestais realizados a cada dois anos a partir do segundo após o plantio. Foram utilizados dados de altura dos inventários executados em maio de 2014 e 2016. Tendo idades de 9 e 11 anos, respectivamente. Os talhões utilizados foram 88, 89, 90, 91, 92 e 93. Foram mensuradas as alturas das árvores em 47 parcelas com área de aproximadamente 1.551 m² cada. Posteriormente, foi calculado o índice de uniformidade. A correlação foi feita através do coeficiente de correlação de Pearson. Os resultados do trabalho mostram ser possível acompanhar o desenvolvimento da Teca com a utilização de imagens de satélite em conjunto com dados de inventário florestal

Measurement of the Depth of Maximum of Extensive Air Showers above 10^18 eV

We describe the measurement of the depth of maximum, Xmax, of the longitudinal development of air showers induced by cosmic rays. Almost four thousand events above 10^18 eV observed by the fluorescence detector of the Pierre Auger Observatory in coincidence with at least one surface detector station are selected for the analysis. The average shower maximum was found to evolve with energy at a rate of (106 +35/-21) g/cm^2/decade below 10^(18.24 +/- 0.05) eV and (24 +/- 3) g/cm^2/decade above this energy. The measured shower-to-shower fluctuations decrease from about 55 to 26 g/cm^2. The interpretation of these results in terms of the cosmic ray mass composition is briefly discussed.Comment: Accepted for publication by PR
