11 I n the United States and most industrialized countries, cardiovascular disease and cancer are ranked as the leading causes of death. These diseases have been linked to lifestyle choices, one of the most important of which is diet. It has been estimated that eating a healthy diet could prevent 30 percent of all cancers. Many of us as children were told to “eat your vegetables because they ar...

Organic labels potentially play an important role in shaping consumer preferences for organic food products. Information implied by the presence of labels can be used by consumers to facilitate their consumption decisions. Therefore, we investigate the influence of the provision of objective information on the willingness-to-pay of consumers for labeled organic apples in Flanders (Belgium). Ini...

Difenoconazole was a triazole fungicide with proven bio-efficacy which leads to morphological and functional changes in the fungal cell membrane. In this work, field trials were conducted in three apple orchards. Sampling methods were improved in both the terminal residual and dissipation experiments. Residual data were analyzed and results showed that, at both recommended rates with 3 times ap...

Eleven Alternaria alternata strains isolated from Red Delicious apples in cold storage in Argentina, were tested for alternariol and alternariol methyl ether production in laboratory media and in whole fresh fruits. Most of them were able to produce both toxins in all media. They were detected also in mycelium free filtrates from liquid cultures and in asymptomatic tissues from inoculated fruit...

Numerical schemes for Einstein’s vacuum equation are developed. Einstein’s equation in harmonic gauge is second order symmetric hyperbolic. It is discretized in four-dimensional spacetime by Finite Differences, Finite Elements, and Interior Penalty Discontinuous Galerkin methods, the latter related to Regge calculus. The schemes are split into space and time and new time-stepping schemes for wa...

This study aims to determine the concentration of phenol in different types of apples (green, yellow and red), tea and coffee. Samples were taken from different sources and were determined by spectrophotometric method. One sample of each type of apple (green, red, yellow) coffee and tea were considered. The results show high concentration of phenol in all samples of apples, coffee and tea compa...
