Aerodynamic properties of solid materials have long been used to convey and separate seeds during harvest and postharvest operations. In this study, the terminal velocities of chickpea (Cicer arietinum L.) and dry bean (Phaseolus vulgaris L.) seeds as a function of seed mass and projected area were determined and also it was predicted by the fuzzy knowledge-based model. The results showed that the terminal velocity increased non linearly from 6.46 to 7.567m s-1 for chickpea and from 5.224 to 6.463 m s-1 for dry bean with an increase in seed mass and projected area. In this paper, a sophisticated intelligent model, based on Mamdani approach fuzzy modeling principles, was developed to predict the terminal velocities of chickpea and dry bean seeds. The verification of the proposed model is achieved via various numerical error criteria. The relative error of predicted values was found to be less than the acceptable limits (10%).

Peyronie's disease, which occurs with the formation of a fibrous plaque in the tunica albuginea; is a disease that causes some physical problems such as bending and shortening of the penis. There are surgical treatment methods of this disease as well as non-surgical treatment methods. Non-surgical treatment methods, which are grouped under six headings: oral treatments, topical treatments, traction and vacuum treatments, shock wave therapy, intraplate injection treatments, and experimental treatments, can be preferred in cases where the symptoms are not very advanced because they provide advantages in terms of ease of application, accessibility, and cost. Although the only non-surgical treatment method approved by the FDA (U.S. Food and Drug Administration) yet is clostridium collagenase histolikum, which is used in intraplaque injection, studies have shown that other methods also reduce curvature, pain, and plaque volume.
