Notas de Población Vol.31 N° 78

El número 78 de la revista Notas de Población se inicia con el artículo de Edith Pantelides, en el cual se revisan los conocimientos sobre los aspectos sociales que inciden en las diferencias en maternidad adolescente en América Latina, la autora destaca aspectos macrosociales -políticas públicas- y sociales próximos -lugar de residencia de las jóvenes, disponibilidad de recursos para la atención en salud reproductiva y la anticoncepción, estructura familiar-, como también características individuales de las adolescentes, entre las que se cuentan la edad, el estrato socioeconómico, el nivel de educación y la pertenencia a grupos étnicos. En el segundo artículo, Luís Rosero-Bixby examinan las tendencias de la fecundidad en 15 áreas metropolitanas, correspondientes a siete países latinoamericanos, con el propósito de determinar si la región está a punto de traspasar el umbral de la fecundidad de reemplazo y cuáles son las probabilidades de llegar a fecundidades extremadamente bajas, como las registradas en España. Por otra parte, el estudio de García y Rojas busca aportar información y elementos de reflexión sobre las tendencias que distinguen a la formación y disolución de las uniones conyugales en América Latina en un marco de desigualdad social y de género, característico de los países de la región. Por su parte, Patricio Aroca en el artículo "Migración intrarregional en Chile. Modelos y resultados 1987-2002", revisa de manera sintética un conjunto amplio de teorías económicas sobre la migración considerando sus aplicaciones a distintas modalidades de migración -entre campo y ciudad; entre regiones; contratada o especulativa- y su pertinencia para países en desarrollo. Con el objetivo de comprender y analizar las políticas sobre vejez en la región, en el artículo de Sandra Huenchuan "Políticas de vejez en América Latina: elementos para su análisis y tendencias generales" se exponen los conceptos de vejez y de calidad de vida, para luego plantear una definición de las políticas tanto públicas como sobre vejez y analizar las tendencias generales de las políticas dirigidas a los adultos mayores en algunos países de la región que cuentan con dichos instrumentos. En esta edición se incluye también la Estrategia Regional de implementación para América Latina y el Caribe del Plan de Acción Internacional de Madrid sobre el envejecimiento, que adoptaron os países de América Latina y el Caribe participantes en la Conferencia regional intergubernamental sobre envejecimiento: hacia una estrategia regional de implementación para América Latina y el Caribe del Plan de Acción Internacional de Madrid sobre el Envejecimiento, celebrada en Santiago de Chile, del 19 al 21 de noviembre de 2003.

A importância do incentivo ao desenho infantil

The present work's objective is to analyze the benefits of drawing for child development, encouraging children to draw. By doing this research, we want to prove the strengths that drawing can bring to the life of a child in areas such as emotional, intellectual, social, perceptual and motor development, seeking ways to encourage drawing for children. This research is bibliographic and focuses on authors like Viktor Lowenfeld, Robert Read, Edith Derdik, Georges-Henri Luquet, Ana Mae Barbosa and others who advocate drawing as a significant form of expression for child development

O ensino do desenho para crianças e jovens

Through my experiences as a teacher assistant in a free course design, I seek to understand the intentions and needs of children and youth with the design, so as to work it in a more consistent as the season and wishes of each student. For this I seek aid in studies on children's drawing of Derdyk Edith and also in observing the relationships that children and young people have with the drawing held in my practice as a teacher. Still reflect on the design in some of its particulars, especially concerning the optics of some artists and scholars of the practice of drawing. At the end of the study, propose suggestions for practices to be developed with children and young people who would be various forms of working drawing with experimental forms of building graphics, aiming so that students can add these unique experiences to broaden their understanding of design as well as its arch graphic possibilities. Thus inspired, especially in Derdyk considerations about the experimental design, I can conclude that through experimentation, we can offer young people a diverse thinking design and the possibilities of conceiving it.

The effect of thermal cycling on the shear bond strength of porcelain/Ti-6Al-4V interfaces

The aim of the study was to evaluate the effect of thermal cycling on the shear bond strength of the porcelain/Ti-6Al-4V interfaces prepared by two different processing routes and metallic surface conditions. Polished and SiO2 particle abraded Ti-6Al-4V alloy and Triceram bonder porcelain were used to produce the interfaces. Porcelain-to-metal specimens were processed by conventional furnace firing and hot pressing. Thermal cycling was performed in Fusayama's artificial saliva for 5000 cycles between 5 +/- 1 and 60 +/- 2 degrees C. After thermal cycling, shear bond tests were carried out by using a custom-made stainless steel apparatus. The results were analyzed using t-Student test and non-parametric Kruskal-Wallis test (p<0.01). Most of the polished-fired specimens were fractured during thermal cycling; thus, it was not possible to obtain the shear bond strength results for this group. Sandblasted-fired, polished-hot pressed, and sandblasted-hot pressed specimens presented the shear bond strength values of 76.2 +/- 15.9, 52.2 +/- 23.6, and 59.9 +/- 22.0 MPa, respectively. Statistical analysis indicated that thermal cycling affected the polished specimens processed by firing, whereas a significant difference was not observed on the other groups. (C) 2015 Elsevier Ltd.

How do titanium and Ti6A14V corrode in fluoridated medium as found in the oral cavity? an in vitro study

The purpose of this work was to evaluate the corrosion of commercially pure (CP) titanium and Ti6Al4V in vitro at different F- concentrations regularly found in the oral cavity by using different electrochemical tests and surface analysis techniques. electrochemical impedance spectroscopy (EIS), open circuit potential (OCP) and potentio-dynamic polarization tests were associated to advanced characterization techniques such as SEM, EDS, AFM, ICP-MS and XPS. OCP tests revealed a higher reactivity of both CP titanium and Ti6Al4V at 12,300 ppm F- concentration than that recorded at 227 ppm F-. Also, a significant decrease of the corrosion resistance of both materials was noticed by EIS in fluoride solutions. Material loss caused by corrosion was noticed on titanium surfaces by SEM and AFM in the presence of high F- concentration. CP titanium degraded by pitting corrosion while Ti6Al4V suffered from general corrosion showing micro-cracks on surface. Furthermore, a high release of metallic ions from the test samples after immersion at high F concentrations was detected by ICP-MS, that can be potentially toxic to oral tissues.

A technique for the determination of the available oxygen in living carp (Cyprinus carpio) muscle

1. 1. A polarographic method for the measurement of the available oxygen in the muscle of living carp by the use of a platinum microelectrode is proposed. 2. 2. The oxygen and the reference electrodes were assembled in a single insertion piece which was implanted in the muscle of a living carp maintained in a special experimental chamber. 3. 3. Curves for normal oxygen levels corresponding to air-saturated water, as well as to a carbogene-saturated water, were obtained. 4. 4. The method can be considered adequate for the measurement of tissue oxygen in living fishes. © 1984.

Signos neurológicos asociados a pacientes caninos con linfoma

Cancer alters the structure or functions of adjacent organs with their sole presence, and subsequent clinical manifestations, but can also cause harmful effects in distant organs. These clinical changes induced by non-invasive tumor action are of great clinical diversity and are known as paraneoplastic syndromes. This paper describes four cases of canine patients with neurological disorders associated to generalized superficial lymphadenopathy.
