L'adquisició del catalá en una nena monolingüe dels 2 anys i 3 mesos als 3 anys i dos mesos. 'La adquisición del catalán en una niña monolingüe desde los 2 años y 3 meses hasta los 3 años y 2 meses'.

Establecer un orden en las flexiones catalanas que posibilite la comparación con otros estudios. La muestra la compone un solo individuo, niña de 2 años y 3 meses (al empezar la investigación, tres años y tres meses al terminarla), de ámbito socio-cultural medio, lengua materna catalana (residente en Badalona). La investigación lineal (12 meses) se articula alrededor de la bibliografía consultada y de las grabaciones (18 sesiones de 30-45 minutos) y análisis mediante el MLU de Brown, del lenguaje del sujeto de la muestra. Grabaciones magnetofónicas (18 grabaciones de 30, 45 minutos cada una). Bibliografía. MLU de Brown adaptado al catalán por Vilá (pero con las normas de cálculo de Brown). La adquisición de las flexiones es el resultado de un nivel determinado de complejidad cognitiva y lingüística, pero no se discierne en qué medida intervienen ambos factores. Para conocer cómo influyen los aspectos semánticos, sintácticos, pragmáticos y fonológicos en la adquisición del lenguaje son necesarios estudios transversales en niños bilingües.

El juego infantil desde la coeducación (3-8 años) = Haur jolasa hezkidetzan (3-8 urte).

Material publicado por el Departamento de Educación, Universidades e Investigación del Gobierno Vasco. Se trata de materiales curriculares que pretenden servir para la formación del profesorado y que ejemplifican y marcan pautas para el trabajo según los nuevos planteamientos curriculares de la LOGSE. Este trabajo se propone analizar diversos ámbitos de la escuela. Partiendo del análisis de las situaciones informales que se dan en la vida escolar (sesiones de psicomotricidad, juego libre, recreo, pasillos, etc.), pretende trabajar desde esas situaciones para terminar en prácticas concretas del quehacer cotidiano en las escuelas. La mayoría de los recursos van en la dirección de romper los grupos habituales y de favorecer la diversidad de interacciones. Intenta trasvasar recursos provenientes del ámbito de la psicomotricidad al de la coeducación y hace un análisis y clasificación de los viejos y nuevos modelos de juego y las funciones que potencian, teniendo en cuenta que el juego es la actividad principal en estas edades y donde mejor se observan las actitudes y valores de niños y niñas.

Tensor3D: A computer graphics program to simulate 3D real-time deformation and visualization of geometric bodies

Tensor3D is a geometric modeling program with the capacity to simulate and visualize in real-time the deformation, specified through a tensor matrix and applied to triangulated models representing geological bodies. 3D visualization allows the study of deformational processes that are traditionally conducted in 2D, such as simple and pure shears. Besides geometric objects that are immediately available in the program window, the program can read other models from disk, thus being able to import objects created with different open-source or proprietary programs. A strain ellipsoid and a bounding box are simultaneously shown and instantly deformed with the main object. The principal axes of strain are visualized as well to provide graphical information about the orientation of the tensor's normal components. The deformed models can also be saved, retrieved later and deformed again, in order to study different steps of progressive strain, or to make this data available to other programs. The shape of stress ellipsoids and the corresponding Mohr circles defined by any stress tensor can also be represented. The application was written using the Visualization ToolKit, a powerful scientific visualization library in the public domain. This development choice, allied to the use of the Tcl/Tk programming language, which is independent on the host computational platform, makes the program a useful tool for the study of geometric deformations directly in three dimensions in teaching as well as research activities.

Avaliação e correlação da presença de endotoxinas e MMP-3, -8 e -9 em canais radiculares com necrose pulpar submetidos ao tratamento endodôntico - estudo in vivo

It is know that endotoxin and various matrix metalloproteinases (MMPs) are involved in the development of periapical lesions. The purpose of this study was to evaluate and correlate the presence of endotoxins and MMP- 3, MMP-8 and MMP-9 in root canals of teeth with necrotic pulp and periapical lesion before, during and after the biomechanical preparation (PBM) using a combination of different irrigations solutions and intracanal dressing. Thirty-three single-root teeth with a diagnosis of pulp necrosis and periapical lesion radiographically visible were selected. Immediately after the coronal opening was collected the first sample from the root canal content. Then, all canals were prepared (cervical and middle thirds) by oscillatory instruments (EndoEze) and irrigated by 2.5% NaOCl. After, a manual preparation was made for the apical third and the teeth were divided into three groups according to the irrigation protocol: G1) 2.5% NaOCl (4 manual files); G2) 2.5% NaOCl (2 manual files) + [Ca (OH)2 0.14%] (2 manual files) and G3) 2.5% NaOCl (2 manual files) + polymyxin B (2 manual files). After the PBM, the second sample was collected; then the third collect was performed after using EDTA final flush. The fourth sample was collected 14 days after placing the dressing [2% chlorhexidine gel + Ca(OH)2]. Quantification of endotoxins was performed by a kinetic chromogenic lysate from amoebocytes of Limulus (LAL) and quantification of MMPs by ELISA assay. The results were analyzed statistically by Kruskal-Wallis and Dunn's test (5%) and ordinal Spearman correlation. Presence of endotoxin was observed in 100% of cases and G3 showed the greatest reduction of endotoxins from the 1st to the 2nd samples (97%), being statistically similar to G2 (84.2%) and different from G1 (49.4%) (p<0.05). The intracanal dressing promoted a significant reduction of endotoxin, no difference among the groups. For...

Tolkning av rekvisitet ”Annat socialt nedbrytande beteende” i § 3 LVU

Syfte med uppsatsen är att ge en bättre förståelse av vad som menas med begreppet ”annat socialt nedbrytande beteende” i § 3 LVU och visa eventuella skillnader i hur lagstiftningen, domstolar och socialtjänsten använder detta begrepp. Vi har undersökt hur begreppsdefinitionen har utvecklats genom lagstiftningsprocessen och hur den återspeglas i förarbeten, juridisk litteratur, prejudikat och praxis. Uppsatsen är skriven utifrån en juridisk metod. Vi genomförde åtta semistrukturerade intervjuer med socialsekreterare i Hälsingland och en länsrättsdomare för att ta reda på hur dessa använder begreppet. Vi har gjort en sammanställning av olika problembeteenden som ungdomar kan uppvisa och diskuterat om dessa är socialt nedbrytande beteende i lagens mening. I lagstiftningen är definitionen av rekvisitet diffus och generell, detta innebär problem för socialsekreterare att använda rekvisitet. Socialsekreterarna är inte vana och tillräckligt utbildade att använda begreppet vilket kan leda till en mindre rättssäker prövning för den enskilde.

5a-Butyl-1,3,8,10-tetra-chloro-7,13-bis-(4-nitro-benzo-yl)-5a,6a,12a,12b-tetra-hydro-7H,13H-thieno[2,3-b:4,5-b']bis-(1,4-benzoxazine)

The title compound, C(34)H(24)Cl(4)N(4)O(8)S, is a linear penta-cyclic system formed of two substituted benzoxazinyl groups fused to 2-n-butyl-tetra-hydro-thio-phene. The oxazine ring, which is fused to the n-butyl-substituted side of the thio-phene ring, is in a boat conformation. The other fused oxazine ring and the tetra-hydro-thiene ring are each in an envelope conformation. The bridgehead C atom alpha to both the S and N atoms forms the flap of each envelope. This results in a twist of the penta-cyclic system such that the dihedral angle between the terminal dichloro-benzene rings is 82.92 (8)°. In the crystal, inversion-related mol-ecules form a weakly hydrogen-bonded dimer, with two C-H⋯O inter-actions between an H atom on the oxazine ring and an amide O atom. Additionally, C-H⋯O inter-actions occur between an H atom on a screw-related nitro-benzene ring and an O atom on the nitro-benzene ring of one mol-ecule. One of the Cl atoms and the butyl group are disordered over two sets of sites with occupancy ratios of 0.94 (2):0.06 (2) and 0.624 (4):0.376 (4), respectively.

AccessMod 3.0: computing geographic coverage and accessibility to health care services using anisotropic movement of patients

Background Access to health care can be described along four dimensions: geographic accessibility, availability, financial accessibility and acceptability. Geographic accessibility measures how physically accessible resources are for the population, while availability reflects what resources are available and in what amount. Combining these two types of measure into a single index provides a measure of geographic (or spatial) coverage, which is an important measure for assessing the degree of accessibility of a health care network. Results This paper describes the latest version of AccessMod, an extension to the Geographical Information System ArcView 3.×, and provides an example of application of this tool. AccessMod 3 allows one to compute geographic coverage to health care using terrain information and population distribution. Four major types of analysis are available in AccessMod: (1) modeling the coverage of catchment areas linked to an existing health facility network based on travel time, to provide a measure of physical accessibility to health care; (2) modeling geographic coverage according to the availability of services; (3) projecting the coverage of a scaling-up of an existing network; (4) providing information for cost effectiveness analysis when little information about the existing network is available. In addition to integrating travelling time, population distribution and the population coverage capacity specific to each health facility in the network, AccessMod can incorporate the influence of landscape components (e.g. topography, river and road networks, vegetation) that impact travelling time to and from facilities. Topographical constraints can be taken into account through an anisotropic analysis that considers the direction of movement. We provide an example of the application of AccessMod in the southern part of Malawi that shows the influences of the landscape constraints and of the modes of transportation on geographic coverage. Conclusion By incorporating the demand (population) and the supply (capacities of heath care centers), AccessMod provides a unifying tool to efficiently assess the geographic coverage of a network of health care facilities. This tool should be of particular interest to developing countries that have a relatively good geographic information on population distribution, terrain, and health facility locations.

Rendering Falling Leaves on Graphics Hardware

There is a growing interest in simulating natural phenomena in computer graphics applications. Animating natural scenes in real time is one of the most challenging problems due to the inherent complexity of their structure, formed by millions of geometric entities, and the interactions that happen within. An example of natural scenario that is needed for games or simulation programs are forests. Forests are difficult to render because the huge amount of geometric entities and the large amount of detail to be represented. Moreover, the interactions between the objects (grass, leaves) and external forces such as wind are complex to model. In this paper we concentrate in the rendering of falling leaves at low cost. We present a technique that exploits graphics hardware in order to render thousands of leaves with different falling paths in real time and low memory requirements.
