This study was aimed to save Thompson Seedless grapes and quality has been preserved through cold storage using an edible covering made from propolis and aloe vera gel. Thompson grapes have high value economically, but after they are picked, their shelf life is reduced due to a rapid decline in quality. Based on the rapid weight loss, low carotene content, softening, and frequent berry degradation, uncoated berries exhibited a rapid deterioration at 5°C and 85–90% relative humidity (RH). On the contrary, the above criteria relating to post-harvest quality losses were greatly delayed in those berries treated with propolis and aloe vera gel and may extend the storability up to 30 days at 5°C.

The modal properties of optical fibers were calculated at core radii (1.45–5.05) µm in 1.20 µm increments. In this work, the calculation was performed at a wavelength of 1.030 µm using the RP Fiber Calculator software (free version 2025). The results demonstrated that when the core radius is comparable wavelength, the fiber supports only the fundamental mode, indicating single-mode operation; whereas larger core radii lead to multimode behavior. The study involved analyzing optical properties of step index fibers with core and cladding refractive indices of  = 1.469 and  = 1.46, respectively. The computed properties included the cut-off wavelength, effective area, power in the core, effective refractive index, and propagation cons

  Tomato (Lycopersicon esculentum Mill) and cucumber (Cucumis sativus L.)  seeds were imbided with water at 10°c or 4°c for 4, 8, and 16 hours before planting to study germination rate, mean germination time, and final germination percentage as well as electrolyte leakage from chilled seeds. Seeds imbided more water at 10°c compared to that at 4°c. Coefficient velocity of germination and final percent of germination decreased with the decrease of temperature and increasing time of imbibition. Germination percent under laboratory conditions was higher than that under field conditions. Also, it was found that tomato seeds were more sensitive to chilling imbibition. Electrolyte leakage increased as temperature of imbib

A static analysis of cellular plate structures of linearly varying depth is presented by using the
simplified grillage method. The cellular plate structure in this study consists of top and bottom
flange plates (non-parallel) separated by longitudinal webs having varying depth. A variational
formulation of thin-walled beam element with linearly varying depth has been carried out for the
derivation of the stiffness matrix of the grillage members for various warping restraint effects. The
effect of warping restraint in stiffness is included by two methods, firstly; the implicit method
(through the torsional constant) and secondly; by the explicit method (as independent warping
degree of freedom). Two diff

One of the most important phenomenon that occurs in sheet metal forming processes is the spring-back, which causes several geometrical alterations in the parts. The accurate prediction of springback after bending unloading is the key to the tool design, operation control, and precision estimate concerning the part geometry. This study investigated experimentally the effect of pretension in three rolling direction (0, 90, 45 degree) on the springback behavior of the yellow brass, sheet under V shape bending die. The pre-tension ranges from five different levels starting of 11% to 55% from the total strain in each rolling direction by regular increase of 11 %, then bent on a V-die 90 degree for the springback estimate. From experiment the
