In this paper, we describe the eBag, the individual pupil’s repository for digital material as a supplement to the physical school bag. The eBag is a flexible software infrastructure in which children can access their digital material with a seamless login.

The anthocyanins of the fruit skin of Iranian forest pear (Sange Khouj) were separated, identified and quantified using high-performance liquid chromatography/diode array detection (HPLC/DAD) and HPLC/electrospray ionization /mass spectrometry (HPLC/ESI /MS). The individual anthocyanins were identified by comparing their mass spectral data and retention times with those of standards and publish...

In order to simulate the usage of brackish irrigation water in greenhouse tomato (Lycopersicum esculentum Mill. cv. Daniela) culture in perlite, plants were supplied with nutrient solutions containing 0, 20, 40, and 60 mM NaCl. The three highest salinity treatments were applied at three different plant growth stages, during early vegetative growth [16 days after transplanting, (DAT)], beginning...

ResumoA realização de metodologias cruzamentos é uma importante atividade no desenvolvimento programas melhoramento florestal, em razão da necessidade do incremento das características genéticas e qualidade na produção espécies frutíferas. Diante disso, considerando o potencial frutífero espécie Psidium cattleyanum (Araçá-Amarelo), esta pesquisa teve como objetivo estabelecimento técnicas nesta...

Avocado (Persea americana Mill.) fruit is a valuable product and notorious for the difficulties encountered in determining quality. Typically the degree of ripeness of many climacteric fruits, such as avocado, is measured by assessing flesh firmness. The aim of the presented work was to elucidate the temporal and spatial changes in texture, biochemistry and micro-structure in different avocado ...

The color of tomato (Solanum lycopersicum) fruit flesh is often used as an indicator of quality. Generally, fruit color is determined by the accumulation of carotenoids and flavonoids, along with concomitant degradation of chlorophylls during ripening. Several genes, such as phytoenesynthetase1 (Psy1), STAY-GREEN (SGR), and SlMYB12, have been extensively studied to elucidate the genes controlli...

This study aimed to examine individual, behavioural and home environmental factors associated with frequency of consumption of fruit, vegetables and energy-dense snacks among adolescents. Adolescents aged 11-12 years (n = 521, 48% boys) completed a paper-based questionnaire during class-time which included a Food Frequency Questionnaire assessing their consumption of fruit, vegetables, and ener...

Xyloglucan endotransglycosylase/hydrolase (XTH) enzymes have played a role in the remodeling of cell wall hemicelluloses. To investigate the function of XTHs in persimmon (Diospyros kaki L.) fruit development and postharvest softening, five cDNAs (DkXTH1 to DkXTH5), whose putative proteins contained the conserved DEIDFEFLG motif of XTH, were cloned. Real time quantitative PCR analysis revealed ...

The aim of this study was to determine organic acids and individual sugars as well as carotenoids in fruit of Kumquat[Fortunella margarita (Lour.) Swingle] on different rootstocks.  On other hand, the purpose of this study was to identify the rootstock that could produce the highest amount of sugars. The content of individual sugars and organic acids in fruits were determined by HPLC, ...
