A new species of freshwater amphipod, Pseudingolfiella possessionis n. sp. (Senticaudata, Pseudingolfiellidae), is described from the submerged moss vegetation of small brooklets at sub-Antarctic Île de La Possession, Crozet archipelago. It constitutes the second freshwater amphipod species known for the sub-Antarctic and Antarctic region, and the fourth member of the genus. The main characters...

This paper details a free surface method using an explicit time stepping scheme for use in z-coordinate ocean models. One key property that makes the method especially suitable for climate simulations is its very stable numerical time stepping scheme, which allows for the use of a long density time step, as commonly employed with coarse-resolution rigid-lid models. Additionally, the effects of ...

In this work, we perform numerical simulation of fluid mixing in a floor-grooved micro-channel with wavy sidewalls which may impose perturbation on the helical flow induced by the slanted grooves on the channel floor. The perturbation is caused by separation vortices in the recesses of the wavy-walled channel as the Reynolds number is large enough. The results show that the effects of the wavy ...

The wind pressure coefficient is essential for calculating the loads on greenhouses. single-span arched greenhouses built in valleys differs from those plain regions. To promote our understanding of characteristics and ensure structural safety valley areas, an analysis distribution law required. Firstly, we carried out a survey greenhouse undulate terrain near Tibet measured air density Lhasa, ...

Individual re-identification is critical to track population changes in order assess status, being particularly relevant species with conservation concerns and difficult access like marine organisms. For this, we propose photo-identification via deep learning as a non-invasive technique discriminate between individuals of the undulate skate (Raja undulata). Nevertheless, accruing enough trainin...

Aspects of the population dynamics of the undulate ray, Raja undulata (Chondrichthyes: Rajidae), one of the more abundant elasmobranch ¢shes captured along the Portuguese south coast (Algarve), were studied for the ¢rst time. Some traditional elasmobranch vertebral enhancing techniques were compared and the most precise for this species determined to be the cedar wood oil immersion and the aliz...

Plant products play a crucial role in the hepatoprotection through its antioxidants property. Therefore, search for modern medicine of plant origin with this property has become a central focus on hepatoprotection today. This study investigated to search a new hepatoprotective agent from natural sources, the methanol extract of folk medicinal plant, T. undulata leaves was tested against liver d...

Fuel cells are being pursued for a wide variety of applications due to their high theoretical efficiency and environmental friendliness [1, 2]. In particular, proton exchange membrane fuel cells (PEMFCs), because of the advantages of low temperature operation, fast start-up, system robustness and low emissions, are attractive for automotive and portable applications [3]. However, commercialisat...
