Prevalencia de Anomalías Dentomaxilares y Necesidad de Tratamiento en Adolescentes

Dentomaxillary anomalies are a public health problem in Chile, resulting in the need for screening and prioritization of treatment. Dentomaxillary anomalies affecting the aesthetics can be a barrier to social integration of adolescents. The Dental Aesthetic Index (DAI) is an instrument to prioritize the need for treatment of malocclusions. The purpose of this research was to characterize the malocclusions, orthodontic treatment needs and esthetic self-perception in schoolchildren from 12 to 15 years through DAI. Prevalence Study in 12 to 15 year-old adolescents from Viña del Mar. The exclusion criteria was previous orthodontic treatment. The sample was 204 subjects selected by uniform allocation with a confidence level of 95 %. Variables included age, type of educational establishment, sex, aesthetic perception and DAI by component. Prevalence of dentomaxillary anomalies by DAI was 63 % [56 % 70 %], CUETO, A. ; SKOG, F. ; MUÑOZ, M; ESPINOZA, S. ; MUÑOZ, D. & MARTÍNEZ, D.

Economic Performance of Pre-Crops in a Three-Year Rotation Program for Organic Vegetable Production

A four year experiment is being carried out, at Ege University Department of Horticulture, in which three different pre-crops are tested under an organic management system as compared to fallow. The aim of the experiment is to identify the most suitable rotation program for organic vegetable production in Turkey. Vicia sativa (common vetch), Brassica oleracea var. italica (broccoli), Vicia faba ‘Sevilla’ (faba bean) and fallow are tested as preceding (winter) crops. During the experiment carried out between 2007 and 2009, the main crops were tomato (2007), zucchini (2008) and pepper (2009). Broccoli represented the farmers’ choice as a winter vegetable. Vetch (incorporated) and faba bean (partially harvested and incorporated) were selected as legumes well adapted to the regional conditions. Soil fertility was maintained by incorporation of the crop residues at the end of both cycles and addition of organic-certified commercial compost (Bioaktif) and compost tea during the main cycle. All the management, including disease and pest management, was carried out according to the organic regulations valid in Turkey and the EU. During the production seasons, all variable costs and revenue, during both the pre-crop and main crop cycles, were recorded and gross margin calculated for each treatment. Economic analysis showed that broccoli as a pre-crop required the highest variable costs followed by faba bean, vetch and fallow, in all three years. Total revenue was the highest in plots where broccoli was the pre-crop. It is followed by faba bean plots mostly because higher yields were obtained in main crop plots following faba bean. The least profitable was fallow – main crop rotation. Broccoli plants also have some extra benefits like adding a high amount of biomass to soil and suppressing weed growth due to shading and allelopathic effects.
Subtidal reef fish and macrobenthic community structure at the temperate Juan Fernández Archipelago, Chile

The Juan Fernandez Archipelago (33o37'S, 78o51'W), an isolated group of islands 650 km west of continental Chile, has a high degree of endemism in its marine biota. Despite numerous scientific expeditions to these islands that have identified this high endemism, few studies have attempted to identify patterns of community structure in subtidal habitats. Using visual census, we surveyed fish and habitat associations at five sites located at two of the three islands of the archipelago. Given the isolation of the archipelago we asked: What is the composition of the reef fish fauna at these isolated islands? What habitats dominate subtidal environments? What influences the abundances of reef fishes? Our analysis confirms that fish communities at the archipielago are dominated by endemic species. The ichthyofauna is comprised of a mixture of subtropical and temperate taxa, with greater similarity to western than eastern South Pacific fauna. We identified different fish assemblages at wave-exposed and wave-sheltered sites. Brown and red macroalgae were correlated with the abundances of some reef fishes. Four broad trophic categories of reef fishes were present at the archipelago, with invertebrate consumers dominating abundance. To our knowledge, this is the first attempt to quantify patterns of community structure in subtidal environments at the Juan Fernandez Archipelago.
Building lighting energy consumption modelling with hybrid neural-statistic approaches

In the proposed work we aim at modelling building lighting energy consumption. We compared several classical methods to the latest Artificial Intelligence modelling technique : Artificial Neural Networks Ensembling (ANNE). Therefore, in this study we show how we built the ANNE and a new hybrid model based on the statistical-ANNE combination. Experimentation has been carried out over a three months data set coming from a real office building located in the ENEA 'Casaccia' Research Centre. Experimental results show that the proposed hybrid statistical-ANNE approach can get a remarkable improvement with respect to the best classical method (the statistical one).
miR-182 promotes cell proliferation and invasion by inhibiting APC in melanoma.

OBJECTIVE Common treatment methods have shown a lack of therapeutic effect in melanoma, a type of malignant tumor. The pathogenesis of melanoma is not yet fully clear, therefore, search for a new treatment strategy is urgent. Recent studies have demonstrated that miR-182 is remarkably over-expressed in human melanoma. Our study aimed to explore the underlying mechanism of miR-182 on melanoma. METHODS In this study, the expression level of miR-182 was detected using RT-PCR in melanoma and adjacent tissues as well as in HEM-m, A375, A2058, and WM35 cell lines. Functions of miR-182 were investigated by using CCK-8 on cell proliferation, apoptosis, invasion, and cell cycle on A375 cells. Moreover, expression levels of Frz, Dsh, β-catenin, APC, Axin, GSK-3β, and CK1 were detected by Western blotting after knockdown and overexpression of miR-182. Overexpression of miR-182 and knockdown of APC was used to demonstrate regulated functions in melanoma. RESULTS Expression levels of miR-182 were significantly upregulated in melanoma tissues and cell lines. Overexpression of miR-182 promoted cell proliferation, migration, and invasion while inhibiting cell apoptosis and cell cycle in S phase. Overexpression of miR-182 upregulated expression levels of β-catenin and APC. Overexpression of miR-182 and knockdown of APC inhibited proliferation of melanoma cells and tumors. CONCLUSION Overexpression of miR-182 promotes cell proliferation and invasion by targeting to APC in melanoma. The pathogenesis of miR-182 and APC might provide therapeutic targets for treatment of melanoma in the molecular level.
Stranding events of southern right whales, Eubalaena australis, in southern Brazil

Although international protection has been granted since 1935, southern right whales have only recently shown signs of recovery , possibly due to anthropogenic factors. Off Brazil, illegal hunting of right whales occurred until 1973. This paper reports on surveys co nducted along the southern Brazilian coast and the information recovered on right whale strandings for this area from 1977-1995. In the first 10 years of this period only four cases were registered. However, in contrast, 20 cases were counted during the last nine years. These resu lts are discussed in relation to marine traffic and the fisheries in the area that produce risks of collision and entanglement. Further , the possibility of storm surges being a preponderant factor in the mortalities in this area is presented. These yearly rates are compared with neighbouring areas that are also inhabited by the right whales. Both possibilities fit the hypothesis that the right whales using the Brazil ian coast for breeding may finally be showing signs of recovery.
Tracer measurements in the tropical tropopause layer during the AMMA/SCOUT-O3 aircraft campaign

Abstract. We present airborne in situ measurements made during the AMMA (African Monsoon Multidisciplinary Analysis)/SCOUT-O3 campaign between 31 July and 17 August 2006 on board the M55 Geophysica aircraft, based in Ouagadougou, Burkina Faso. CO2 and N2O were measured with the High Altitude Gas Analyzer (HAGAR), CO was measured with the Cryogenically Operated Laser Diode (COLD) instrument, and O3 with the Fast Ozone ANalyzer (FOZAN). We analyse the data obtained during five local flights to study the dominant transport processes controlling the tropical tropopause layer (TTL, here ~350–375 K) and lower stratosphere above West-Africa: deep convection up to the level of main convective outflow, overshooting of deep convection, and horizontal inmixing across the subtropical tropopause. Besides, we examine the morphology of the stratospheric subtropical barrier. Except for the flight of 13 August, distinct minima in CO2 mixing ratios indicate convective outflow of boundary layer air in the TTL. The CO2 profiles show that the level of main convective outflow was mostly located at potential temperatures between 350 and 360 K, and for 11 August reached up to 370 K. While the CO2 minima indicate quite significant convective influence, the O3 profiles suggest that the observed convective signatures were mostly not fresh, but of older origin (several days or more). When compared with the mean O3 profile measured during a previous campaign over Darwin in November 2005, the O3 minimum at the main convective outflow level was less pronounced over Ouagadougou. Furthermore O3 mixing ratios were much higher throughout the whole TTL and, unlike over Darwin, rarely showed low values observed in the regional boundary layer. Signatures of irreversible mixing following overshooting of convective air were scarce in the tracer data. Some small signatures indicative of this process were found in CO2 profiles between 390 and 410 K during the flights of 4 and 8 August, and in CO data at 410 K on 7 August. However, the absence of expected corresponding signatures in other tracer data makes this evidence inconclusive, and overall there is little indication from the observations that overshooting convection has a profound impact on gas-phase tracer TTL composition during AMMA. We find the amount of photochemically aged air isentropically mixed into the TTL across the subtropical tropopause to be not significant. Using the N2O observations we estimate the fraction of aged extratropical stratospheric air in the TTL to be 0.0±0.1 up to 370 K during the local flights. Above the TTL this fraction increases to 0.3±0.1 at 390 K. The subtropical barrier, as indicated by the slope of the correlation between N2O and O3 between 415 and 490 K, does not appear as a sharp border between the tropics and extratropics, but rather as a gradual transition region between 10° N and 25° N where isentropic mixing between these two regions may occur.
Self-Quotient ε-Filter for Feature Extraction from Noise Corrupted Image

This paper describes a nonlinear filter that can extract the image feature from noise corrupted image labeled self-quotient e-filter (SQEF). SQEF is an improved self-quotient filter (SQF) to extract the image feature from noise corrupted image. Although SQF is a simple approach for feature extraction from the images, it is difficult to extract the feature when the image includes noise. On the other hand, SQEF can extract the image feature not only from clear images but also from noise corrupted images with uniform noise, Gaussian noise and impulse noise. We show the algorithm of SQEF and describe its feature when it is applied to uniform noise corrupted image, Gaussian noise corrupted image and impulse noise corrupted image. Experimental results are also shown to confirm the effectiveness of the proposed method.
Caracterización fisico-química de propóleos argentinos para su uso como biofungicida agrícola

Introducción El propóleos es un producto elaborado por las abejas (Apis mellifera L.) a partir de resinas, gomas y bálsamos exudados por diversas especies vegetales (Ghisalberti, 1978; Bankova et al., 2000). Las abejas pecoreadoras toman estas sustancias utilizando sus mandíbulas y el primer par de patas, las transforman física y químicamente con secreciones salivares propias, forman gránulos de propóleos y los transportan a la colonia en sus sacos corbiculares (Gojmerac, 1980). Una vez en la colmena, las recolectoras esperan entre una y siete horas hasta ser liberadas de su carga con la ayuda de otras abejas (Von Frisch, 1967). En la colmena, el propóleos le proporciona protección física y química a las abejas: es utilizado para barnizar el interior de las paredes, cerrar grietas, reducir al mínimo las vías de acceso, recubrir restos de animales que se encuentren en el interior, consolidar componentes estructurales, evitar vibraciones, aislar térmicamente y asegurar la desinfección de la colmena (Morse, 1975). Todas las celdas, especialmente las recién construidas, son recubiertas con propóleos internamente antes que la reina deposite sus huevos (Caillas, 1978). En promedio, una colmena se abastece con 50 gramos de propóleos al año (Prytzyc, 2003). En Argentina existen tres grandes zonas productoras de propóleos: la zona cuyana y del Alto Valle de Rio Negro (Mendoza, Río Negro y Neuquén), la zona del Delta (sur de Entre Ríos, sur de Santa Fe y Norte de Buenos Aires) y la zona del Centro y Sur de la Provincia de Buenos Aires (Tandil y la costa bonaerense). Durante la temporada apícola se observan tres grandes períodos de entrada de propóleos a la colmena: el primero, que abarca la primavera y las primeras semanas del verano y representa entre un treinta y cuarenta por ciento de la recolección anual; el segundo, durante el verano, donde la entrada de propóleos es poco significativa; y el tercero, que comprende el período desde fines del verano hasta el comienzo del otoño, en donde se observa un ingreso de hasta el setenta por ciento del total (Bedascarrasbure et al., 2006).
CONVERGÊNCIA E COBERTURA DE CURVAS POR SISTEMAS MULTI-ROBÔS

This paper deals with the problems of convergence and coverage of multiple robots in a generic 1-dimensional curve. More specifically, the goal is to design distributed control laws to make a multiagent system converge and distribute itself optimally along the curve. This problem is solved with the use of artificial vector fields for convergence to the curve and Voronoi partitions for the control of the coverage of the multiagent system. Moreover, when considering the presence of an obstacle, robots are able to create auxiliary curves in order to dodge it. The presented methodology is evaluated in simulation, in which four holonomic mobile robots converge to a curve and distribute themselves in it, avoiding collisions with known obstacles. The results graphically show the convergence and distribution of the agents in the curve. Keywords— Mobile robots, vector fields, motion control, coverage control, Voronoi partitions. Resumo— Este artigo trata os problemas de convergência e cobertura de múltiplos robôs em uma curva genérica unidimensional. Mais especificamente, o objetivo é projetar leis de controle distribúıdas para fazer com que um sistema multiagente convirja e se distribua de maneira ótima sobre a curva. Este problema é resolvido com a utilização de campos vetoriais artificiais para convergência para curva e partições de Voronoi para o controle de cobertura do sistema multiagente. Além disso, ao considerar a presença de um obstáculo, os robôs são capazes de criar curvas auxiliares para desviarem-se dele. A metodologia apresentada é avaliada em uma simulação, na qual quatro robôs móveis holonômicos convergem para uma curva e se distribuem nela, evitando colisões com obstáculos conhecidos. Os resultados mostram graficamente a convergência e a distribuição dos agentes na curva. Palavras-chave— Robôs móveis, campos vetoriais, controle de movimento, controle de cobertura, partições de Voronoi.
Replacement of fish meal by poultry by-product meal, food grade, in diets for juvenile spotted rose snapper (Lutjanus guttatus)

The feasibility of replacing fish meal protein at different levels with poultry by product meal food grade (PBM-FG) was assessed in diets for spotted rose snapper Lutjanus guttatus. Four diets were formulated, the control diet fish meal was used as the main protein source (FM); the other three diets had increasing levels of PBM-FG replacing 25, 50 or 75% of the fish meal protein respectively. The diets were fed close to apparent satiation, three times a day to quadruplicate groups of juvenile snapper (average body weight 11.0 ± 0.04 g). The fish were randomly distributed into groups of 15 fish in a 120 L seawater tank. The response of snapper to diets containing graded levels of fish meal was evaluated by measuring weight gain, feed efficiency, body composition, hematological parameters and apparent nutrient digestibility during a 12- week period. The replacing of the 25% of fish meal protein by PBM-FG did show a similar trend for feed efficiency and growth performance than control diet. Feed efficiency and growth performance was reduced at 75% level of fish meal protein replacement by PBM-FG, due to deficiencies of lysine and methionine. The final whole-body proximate composition did not differ among treatments. The hematological characteristics were similar among the treatments control, 25 and 50%, but the fish fed PBM-FG 75% showed the lowest levels for total protein and glucose parameters. The dietary dry matter and protein apparent digestibility coefficients (ADCs) decreased with increasing dietary PBM-FG. High values for lipid ADCs were observed in all diets.

A Study of the Factors Affecting the Purchase Intention on Mobile Game Apps

With the widespread popularity of smartphone and tablet devices, consumers’ demands for mobile application (App) also rockets rapidly nowadays. According to Flurry’s survey, nearly 55 million shipment of smart mobile device were increased in the U.S. market while 1.5 hundred million devices were increased in China Market solely in the past year. This dramatic growth of global smartphone market share also brought about the thriving rise of App. Taiwan Network Information Center (TWNIC) had conducted a survey on Taiwanese’s use of mobile devices in 2012, finding out that their most favorite App was game App and social App was the second. This also showed the increasing growth of mobile device and that game App took the lead for the users in Taiwan. In the background of this rapid development and intensive competition of game App, the developers pay much attention to users’ considerations for purchasing game App and their use behaviors. The researcher of this study used Unified Theory of Acceptance and Use of Technology (UTAUT) as the theoretical framework and further extended its model by adding two dimensions of Price and Product Involvement to investigate consumers’ purchase intention of game App. The results show that the constructs, Performance Expectancy and Social Influence had significant effects on behavioral intention on game app, and Facilitating Conditions and Price had direct effect on their purchase behavior. This study suggested product involvement effects on the factors affecting on purchase intention and behavior. This extended UTAUT also offers significant reference for future studies of purchase intention and behavior.
Use of functional traits to assess changes in stream fish assemblages across a habitat gradient

Functional traits are important for understanding the links between species occurrence and environmental conditions. Identifying these links makes it possible to predict changes in species composition within communities under specific environmental conditions. We used functional traits related to habitat use and trophic ecology in order to assess the changes in fish community composition between streams with varying habitat structure. The relationship between the species traits and habitat characteristics was analyzed using an RLQ ordination analysis. Although species were widely distributed in habitats with different structures, physical conditions did favor some species based on their functional characteristics. Eight functional traits were found to be associated with stream habitat structure, allowing us to identify traits that may predict the susceptibility of fish species to physical habitat degradation.
Strain effect on extracellular laccase activities from Botrytis cinerea

Background and Aims Laccase enzymes produced by Botrytis cinerea are involved in the oxidation of phenolic substances during the development of grey mould, which causes significant economic losses. The aim of this work was to study the structural and activity characteristics of the laccase enzymes secreted by three B. cinerea strains that are involved in the development of grey mould. Methods and Results Laccase enzymes obtained from three B. cinerea strains [one reference strain (B05.10) and two strains obtained from two French vineyards (VA612 and RM344)] were characterised. Analysis by LC‐QTOF‐MS revealed that the three strains contained a mixture of Laccase‐2‐BcLCC2 and Laccase‐3‐BcLCC7. The structural characteristics of the laccases from the three strains, such as molecular weight and glycosylation degree, were identical. Nevertheless, their catalytic activities were significantly different. Conclusions Differences in catalytic activities could be due either to possible differences in the relative amount of Laccase‐2‐BcLCC2 and Laccase‐3‐BcLCC7 produced by each strain or to differences in the glycosidic fraction of the enzymes. Significance of the Study The severity of the infection caused by B. cinerea may be not only related to the infection level but also to the strain involved.
