The aim of this study was to investigate the patulin concentration in apple juice commercialized produced in Mashhad city of Iran after treatment with So2 and heat. Apple Juice samples were analyzed for patulin using reversed-phase high performance liquidated chromatography. The results of this study showed that temperature (90, 107.5 and 125°C for 30&268 min) and SO2 (0&350 ppm) have significant effect on reducing patulin amount. The most effective condition in decreasing patulin was observed at 125°C and 350 ppm which resulted in about 86% reduction of patulin. Results showed that heat and SO2 are the most effortless methods that be recommended for fruit juice industries in preventing infection which has got a major role in the product of patulin in apple juice.Keywords

The progressively decreasing feature size of the circuit components, particles and electronic devices has tremendously increased the need for studying and investigating the nano structural properties of materials. We have grown titanium oxide on the Si (100) substrate at 500°C and one atmosphere pressure. Some researchers have believed that an intermediate silicon oxide film can be made between titanium oxide film and substrate but which turned to be of less use. We added silicon nano particles (100 nm) into titanium oxide film that could modify the titanium oxide morphology as revealed in x-ray diffraction patterns and scanning electron microscopy images. The obtained results show that the existence of silicon nano particles in titanium oxide film resulted in better stability. The improved film can thus be used as a good gate dielectric film for the future CMOS (Complementary metal oxide semiconductor) devices.Keywords

Dianthus is an important decorative plant cultivated from long time ago. This plant is used in vase and stem-cut forms, and is economically valuable due to its production simplicity and reasonable price. The effect of benzyl adenine with concentrations of 25, 50, and 100 mg/L on Dianthus CV. "Cream Viana" cut flower was investigated in short-term treatment (48 hours) in this study. In addition, the effects of nano silver with concentrations of 2 and 4 ppm and 8- hydroxyquinol sulfate with concentration of 300 ppm plus 3% sucrose, as the continuous treatment (preservative solution) studied. The flowers were placed at the temperature of 20°C, relative humidity of 80%, and photo-period of 14 hours provided by fluorescent light with light intensity of 15 micromole/m2×s in the upper part of the room. Life information following picking the flower were all analyzed during the measurement procedures; these parameters included relative wet weight of flower, flower diameter, soluble solids, degree of stem bending, percentage of stability index of cellular membrane, amount of Anthocyanin, and solution uptake. The results indicated short-term treatment by Benzyl adenine of 100 mg/liter concentration together with nano silver preservative solution of 4 ppm concentration plus 3% sucrose has the greatest impact on the longevity and qualitative characteristics of Dianthus flower.Keywords
