La etapa uno se centra en las habilidades de lenguaje oral y prelectura que los niños necesitan para ser lectores competentes. Esta etapa es esencial para:la introducción de los personajes principales. Alentar a los niños a conversar acerca de ellos mismos y sus experiencias en relación con las historias. El desarrollo de destrezas de escuchar. Se presentan las primeras palabras clave. El desarrollo de una actitud positiva hacia la lectura. La enseñanza de habilidades de manipulación del libro. Estas historias de Bif, Chip y Kipper sirven de base para hablar de temas como las relaciones entre hermanos, apodos, cumpleaños, la hora del baño, aprender algo nuevo, y así sucesivamente. Al hablar de sus propias experiencias, los niños sienten una participación personal en los acontecimientos de las historias. El problema que enfrenta el papá es cómo recoger la última manzana del árbol. Se trata de una hermosa manzana, pero esta demasiado alta para llegar a ella.

Ensayo crítico de la obra 'Ideología y curriculo' de Michael W. Apple, editada por Akal en 1986. Se analizan las tesis poco usuales sobre el estudio de los curricula en las escuelas, pues encuentra raíces ideológicas y políticas en la forma y el contenido de los programas de estudio, además de conexiones con los sistemas de valores dominantes en la sociedad. También, destaca la importancia del papel que juegan los profesores en el mantenimiento y transformación de un determinado modelo curricular.

El trabajo describe el proyecto de desarrollo de un SIG 3D de código abierto para dispositivos móviles (Apple-iOS y Android) y para navegadores web con tecnología WebGL. En la fase actual, nos centraremos en el diseño e implementación del globo virtual, como elemento esencial que da soporte al SIG 3D y de una IDE que permite la programación de nuevas funcionalidades al globo. Dentro de los objetivos de diseño del globo virtual tenemos (i) simplicidad, con código estructurado que facilita la portabilidad y con una API de código abierto sencilla, (ii) eficiencia, tomando en cuenta los recursos hardware de los dispositivos móviles más extendidos en el mercado, (ii) usabilidad, implementando una navegación intuitiva mediante gestos para la interacción en pantalla y (iv) escalabilidad, gracias a una API desarrollada, se permite aumentar de las prestaciones mediante el desarrollo de scripts y podrán ser ejecutados tanto dentro del navegador web como de forma nativa en las plataformas móviles. Ante un panorama de clara proliferación de aplicaciones para móviles, Glob3 Mobile pretende ser una apuesta fuerte que llegue a convertirse en un SIG 3D de código abierto que abarque variadas aplicaciones sectoriales, algunas ya en marcha

Two field trials were conducted using established apple (Malus cv. Golden Delicious) and pear (Pyrus communis 'Williams' Bon Chretien') to assess the efficacy of three commercially available systemic inducing resistance (SIR) products, Messenger (a.i. Harpin protein), Phoenix (a.i. Potassium phosphite) and Rigel (a.i. Salicylic acid derivative) applied at four different growth stages of tree development (bud break, green cluster, 90% petal fall, early fruitlet) against the foliar pathogens Venturia inaequalis and Venturia pirina which cause apple and pear scab respectively. A conventional synthetic fungicide (penconazole) used within the UK for apple and pear scab control was included for comparison. Little efficacy as scab protectants was demonstrated when each SIR product and penconazole was applied at only two growth stages (bud break, green cluster). However when the above compounds were applied at three or more growth stages efficacy as scab protectants was confirmed. The synthetic fungicide penconazole provided greatest protection against apple and pear scab in both the 2006 and 2007 field trials. There was little difference in the magnitude of scab protection conferred by each SIR agent. Results suggest application of at least three sprays during bud break to early fruitlet formation with an appropriate SIR agent may provide a useful addition to existing methods of apple and pear scab management under field conditions.

A detached leaf bioassay was used to determine the influence of several film forming polymers and a conventional triazole fungicide on apple scab (Venturia inaequalis (Cooke) G. Wint.) development under laboratory in vitro conditions, supported by two field trials using established apple cv. Golden Delicious to further assess the efficacy of foliar applied film forming polymers as scab protectant compounds. All film forming polymers used in this investigation (Bond, Designer, Nu-Film P, Spray Gard, Moisturin, Companion PCT12) inhibited germination of conidia, subsequent formation of appressoria and reduced leaf scab severity using a detached leaf bioassay. Regardless of treatment, there were no obvious trends in the percentage of conidia with one to four appressoria 5 days after inoculation. The synthetic fungicide penconazole resulted in the greatest levels of germination inhibition, appressorium development and least leaf scab severity. Under field conditions, scab severity on leaves and fruit of apple cv. Golden Delicious treated with a film forming polymer (Bond, Spray Gard, Moisturin) was less than on untreated controls. However, greatest protection in both field trials was provided by the synthetic fungicide penconazole. Higher chlorophyll fluorescence Fv/Fm emissions in polymer and penconazole treated trees indicated less damage to the leaf photosynthetic system as a result of fungal invasion. In addition, higher SPAD values as measures of leaf chlorophyll content were recorded in polymer and penconazole treated trees. Application of a film forming polymer or penconazole resulted in a higher apple yield per tree at harvest in both the 2005 and 2006 field trials compared to untreated controls. Results suggest application of an appropriate film forming polymer may provide a useful addition to existing methods of apple scab management. (C) 2008 Elsevier Ltd. All rights reserved.

Colorectal cancer is one of the most common cancers in Western countries. The World Health Organisation identifies diet as a critical risk factor in the development and progression of this disease and the protective role of high levels of fruit and vegetable consumption. Several studies have shown that apples contain several phenolic compounds that are potent anti-oxidants in humans. However, little is known about other beneficial properties of apple phenolics in cancer. We have used the HT29, HT115 and CaCo-2 cell lines as in vitro models to examine the effect of apple phenolics (0.01–0.1% apple extract) on key stages of colorectal carcinogenesis, namely; DNA damage (Comet assay), colonic barrier function (TER assay), cell cycle progression (DNA content assay) and invasion (Matrigel assay). Our results indicate that a crude extract of apple phenolics can protect against DNA damage, improve barrier function and inhibit invasion (p < 0.05). The anti-invasive effects of the extract were enhanced with twenty-four hour pretreatment of cells (p < 0.05). We have shown that a crude apple extract from waste, rich in phenolic compounds, beneficially influences key stages of carcinogenesis in colon cells in vitro.

Cloudy apple juice has been found to develop off-flavors during storage in daylight. The development of off-flavors and volatile compounds was monitored in reconstituted juice prepared from 'Golden Delicious' and 'Fuji' apple concentrates stored in glass bottles under fluorescent light (3000 Ix, 8 degrees C). A strong metallic off-flavor was formed by photooxidation. A major contributor to the off-flavor was identified as 1-octen-3-one by gas chromatography-olfactometry. In addition, six volatile compounds, pentanal, 2-methyl-1-penten-3-one, hexanal, (E)-2-heptenal, 6-methyl-5-hepten-2-one, and (E)-2octenal, increased significantly after light exposure and could contribute to the off-flavor. Except for pentanal and hexanal, these volatiles were found only after light exposure. Higher levels of volatiles were observed in juice from 'Golden Delicious' apples than in juice from 'Fuji' apples, and this difference was consistent with higher levels of suspended solids. When the suspended solids were removed by centrifugation, the development of volatiles on exposure to light was reduced significantly.

The widely-adopted protocol for the cryopreservation of winter buds of fruit trees, such as Malus and Pyrus, was developed in a region with a continental climate, that provides relatively hard winters with a consequent effect on adaptive plant hardiness. In this study the protocol was evaluated in a typical maritime climate (eastern Denmark) where milder winters can be expected. The survival over two winters was evaluated, looking at variation between seasons and cultivars together with the progressive reduction in survival due to individual steps in the protocol. The study confirms that under such conditions significant variation in survival can be expected and that an extended period of imposed dehydration at -4oC is critical for bud survival. The occurrence of freezing events during this treatment suggests that cryodehydration may be involved, as well as evaporative water loss. To optimize the protocol for maritime environments, further investigation into the water status of the explants during cryopreservation is proposed.
