| Potato cubes were dried by different drying methods. After the end of drying process, the experimental data were first fitted to the four well-known drying models. The results indicated that the logarithmic and page models performed better compared with the other models. Also, in this study neural networks were used in order to possibly predict dried potato moisture ratio (y), based on three input variables of drying time, drying temperature and different methods. The results revealed that, logsig function based on 10 neurons in the first hidden layer could perform as the best goodness configuration for predicting the moisture ratio. The comparison of the obtained results of ANNs and classical modeling indicated that, the neural networks have a higher... |

| The use of medicinal plants by the general population is an old and still widespread practice, which makes studies of their genotoxicity essential. Psidium guajava L. and Achillea millefolium L. are examples of plants commonly used in popular medicine. P. guajava L. is indicated for diarrhea and also as an antiseptic, while A. millefolium L. is indicated as an analgesic, antispasmodic, digestive, diuretic, antiseptic, astringent, emollient, wound healer and hemorrhoid medication. The aim of this study was to determine the effects of the infusions of these two plant species on chromosomes and the cell cycle. Leaves from the plants were used to prepare infusions, in the same manner as teas, but at two different concentrations. Allium cepa L. root-tip cells... |
