Published: January 2023

Ethephon and calcium carbide are artificial ripening compounds that are often used to faster fruit ripening during postharvest. These two compounds were induced in non-ripening (NOR) tomato fruit line MA 131-6-3 because it produced endogenous ethylene and lower respiration. This study aimed to determine the effect of ethephon and calcium carbide on postharvest losses of NOR tomatoes for 14 and 28 days after treatment. Exogenous application of 1,500 ppm ethephon and 15 g kg-1 was given to NOR tomato fruit of line MA 131-6-3 and ambient conditions at temperature 28.08±1.80 °C and relative humidity 75.67±2.09%. This experiment was carried out in Sidoarum village, Godean district, Sleman regency, Special Region of Yogyakarta province, Indonesia, in 125 m above sea level. As a result, ethephon can increase fruit rotting. Furthermore, calcium carbide can accelerate metabolism which has an impact on physiological loss in weight, changing color to yellowish (b*), increasing vivid color (chroma), but the color of tomato fruit cannot turn red.

Reachable Set of Low-Delta-v Trajectories Following a Gravity-Assist Flyby
Authors: Wu Chun-Yi , Russell Ryan P. 
Published: January 2023

Flyby tours are challenging to design due to the extraordinarily large search space. A single algorithm is proposed to answer the question of what low-cost, post-flyby options exist for a spacecraft arriving at a flyby body. The algorithm a) considers the full domain of reachable bodies and transfer types including even- and odd-[Formula: see text] resonant ballistic, nonresonant ballistic, and [Formula: see text]-infinity leveraging; b) identifies families of solutions instead of just single points; and c) structures the search to only seek solutions within a [Formula: see text] threshold. This algorithm extends and integrates these state-of-the-art characteristics, and is designed to rapidly inform an outer-loop pathfinding scheme for flyby tour design. Detailed examples of resulting solutions and families are provided for multiple variations of three different use case scenarios, including tours in the Jupiter, Saturn, and sun systems. As a representative example in the Jupiter system starting at Callisto, the algorithm takes on the order of 0.1 s to find over 500 solutions with [Formula: see text] costs below [Formula: see text] organized into nearly 70 families, all either returning to Callisto or proceeding to Ganymede.
Hypersonic Shock Wave/Turbulent Boundary Layer Interaction over a Compression Ramp
Authors: Zuo Feng-Yuan 
Published: January 2023

A parametric study of ramp-induced planar shock-wave/turbulent-boundary-layer interactions (SBLIs) is carried out at hypersonic conditions (Mach number 6.0) by means of numerical simulation of the Reynolds-averaged Navier–Stokes (RANS) equations, with the eventual goal of establishing wall temperature and Reynolds number effects. Comparison with available experimental data shows that RANS is capable of predicting the main features of hypersonic oblique SBLI, namely, typical size and distribution of the wall-surface pressure, and heat transfer. A large number of flow cases, at low ([Formula: see text]) and high Reynolds number ([Formula: see text]), were computed to examine the scaling of the heat transfer over a wide range of wall temperatures. As expected, the interaction zone of hypersonic ramp-induced SBLI is reduced as the wall is cooled. A simple power law for heat transfer originally introduced by Back and Cuffel (AIAA Journal, Vol. 8, No. 10, 1970, pp. 1871–1873) is here considered to account for hypersonic ramp-induced SBLI, which is found to successfully collapse the data to the distributions obtained for supersonic, cold/hot interactions.
