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...

This study investigated the relative contribution of perception/cognition and language-specific semantics in nonverbal categorization of spatial relations. English and Korean speakers completed a video-based similarity judgment task involving containment, support, tight fit, and loose fit. Both perception/cognition and language served as resources for categorization, and allocation between the ...

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...

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...

Listeria monocytogenes has been used as an experimental live vector for the induction of CD8-mediated immune responses in various viral and tumoral experimental models. Susceptibility of BALB/c mice to Leishmania major infection has been correlated to the preferential development of Th2 CD4 T cells through an early production of interleukin 4 (IL-4) by a restricted population of CD4 T cells whi...

Morphological, structural and developmental features of fruits and seeds of Vismia guianensis (Aubl.) Choisy. are here presented, with the purpose to elucidate their structure and to contribute to taxonomical and ecological studies of the family. The fruit is a berry and the "rind" is constituted by the exocarp and by the subepidermal layers which constitute the mesocarp. The reddish pulp, rich...

Soft robotics offers the unique promise of creating inherently safe and adaptive systems. These systems bring man-made machines closer to the natural capabilities of biological systems. An important requirement to enable self-contained soft mobile robots is an on-board power source. In this paper, we present an approach to create a bio-inspired soft robotic snake that can undulate in a similar ...
