To investigate the effects of salicylic acid dipping and Aloe vera gel coating on shelf life and post harvest quality of table grapes (Vitis vinifera) of the cultivar Shahroudi, a factorial experiment was conducted on the basis of randomized complete blocks design with three factors and three replicates in agricultural faculty of Islamic Azad University in 2014. The treatments were dipping in Salicylic acid (three levels of 0, 1 and 2 mmmol-1 for 15 minutes) and coating with Aloe vera gel (four levels of 0, 10%, 15% and 20% w/v) and measurement of traits in 1st day, 30th day and 60th day after treatment of berries. The results showed that the interaction effect of salicylic acid and Aloe vera gel application was significant on all of traits except for pH value in a way that the best and the minimum weight loss (0.09g) was obtained by application of 2 mmol -1 Salicylic acid and 20% Aloe vera gel in 1 st day after treatment. The greatest amount of total soluble solids (428.43 g.100g -1 fruit juice) was found in 2 mmol -1 Salicylic acid and 15% Aloe vera gel in 60 th day. The highest Catalase enzyme activity (0.0013 Ua.mg -1 Pro) was attained in 2 mmol -1 Salicylic acid and 15% Aloe vera gel in 30 th day. These results demonstrated that treatment of grape berries by salicylic acid and Aloe vera gel had positive effect on shelf life of table grapes and their postharvest quality.
An electromagnetic launcher can be used as an accelerator for yarn attached to a ferromagnetic projectile. As a result, yarn endures a specific amount of tension. In addition to the yarn variables and the type of weft insertion system, the parameters of the weft yarn accelerator strongly affect the weft yarn velocity, its tension, and consequently the fabric quality. An applicable model that can represent the relationship between input and output parameters of this weft insertion system is very useful for predicting the strike of the projectile. Therefore, in this research a 3D imitating launching model was developed by the finite element method. A coil electromagnetic launcher was employed. An experimental methodology using an image-processing technique was also utilized to measure the projectile velocity. Numerical results were compared with experimental results to verify the numerical procedure. A validated model can be a reliable tool to investigate the effects of many process parameters on the strike of the projectile and to optimize them. Therefore, the system parameters can be scientifically defined by this model to insert a weft yarn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
