Aphanius marassantensis, new species, is described from the Kızılırmak River drainage in northern Anatolia based on colouration, meristic and morphometric characters, and the mtDNA COI barcode region. It is distinguished from other Anatolian Aphanius by one or several of the following characters: a stout body shape (BD/SL 28.2-39.6%), complete scale cover, and 25-28 scales along the lateral lin...

The infection dynamics and distribution of the ectoparasitic fish monogenean Neobenedenia sp. (Monogenea: Capsalidae) throughout its development was examined on barramundi, Lates calcarifer (Bloch) (Latidae), by labelling transparent, ciliated larvae (oncomiracidia) with a fluorescent dye. Replicate fish were each exposed to approximately 50 fluorescent oncomiracidia and then examined for paras...

Flat tube heat exchangers with louvered fins were applied in order to meet the performance requirements and compactness in automotive air conditioning systems. Experimental and simulation study focusing on the air side thermal hydraulic performance of automotive heat exchangers were performed in this article. Test results showed that the heat capacity of a condenser with 5.4 mm height louvered ...

As they fly or swim, many animals generate a wake of vortices with their flapping fins and wings that reveals the dynamics of their locomotion. Previous studies have shown that the dynamic interaction of vortices in the wake with fins and wings can increase propulsive force. Here, we explore whether the dynamics of the vortex interactions could affect the predictability of propulsive forces. We...

This chapter analyzes a propulsive force generated from pectoral fins for a manta-like fish robot, which is one of rajiform-type fish robot in a classification of swimming mechanism of fishes, from fluid dynamics aspects. The fishes of this type swim underwater with two pectoral fins. A diving method is proposed, assuming that some front fin rays are fixed with a constant angle. The usefulness ...

To the Editor My original paper on the " Cortical Margining Capabilities of Fins 1 " has been made based on the data studied while I was working at the Cleveland Clinic Foundation as a research fellow. However, this article was submitted to two international journals by me and the co-author at the same time independently. I hereby retract the paper. 1. Jin BH, Kwon HD, Cho YE. Cortical marginin...

Carbon nanostructures have been much sought after for cold-cathode field emission applications. Herein a printing technique is reported to controllably nanostructure chemical vapor deposited graphene into vertically standing fins. The method allows for the creation of regular arrays of bilayer graphene fins, with sharp ridges that, when printed onto gold electrodes, afford a new type of field e...

A thorough understanding of the pectoral fin hydrodynamics of the bluegill sunfish (Lepomis macrochirus) provides insight that can be applied to the design of propulsors for autonomous underwater vehicles (AUVs). The pectoral fin represents a continuously deforming complex moving boundary problem. For the sunfish, both propulsion and maneuvering are entirely controlled by the pectoral fins. Fir...

This paper describes an electroactive polymer robot with ray-like pectoral fins. Electroactive polymers are materials that change their geometry in response to electric field and can be used to replace electromechanical devices. The aim of this study is to show that these materials can be used to build more complicated devices and the behaviour of these devices can be coordinated to some extent...
