On the other hand, the ...

Hand fatigue is one of the major problems of astronauts during Extravehicular Activity (EVA), due to the stiffness of the space suit, in particular of the glove. In order to evaluate the stiffness of EVA gloves, different methods have been proposed in the past, mainly focused on the effects of wearing an EVA glove on hand performance when executing test protocols. In this paper, an objective me...

Elk velvet antler (EVA) has been used in traditional Oriental medicine for centuries to promote general health; however, little evidence for its effect on bone development is available. We investigated the effects of lifelong exposure of Wistar rats to a diet containing 10% EVA on physical growth and bone development. Measurements included weekly body weights, blood chemistry and kidney and tes...

Service Oriented Enterprise (SOE) has brought up requirement for performance measurement of the novel business model in its dynamic and flexible business environment. To solve the problem, conception of SOE is discussed from business perspective firstly, and an operation architecture of SOE is proposed and analyzed. The Service Oriented Economic Value Added (SO-EVA) performance measurement mode...

The earned value technique is a crucial and important technique in analysis and control the performance and progress of mega projects by integrating three elements of them, i.e., time, cost and scope. This paper proposes a new version of earned value analysis (EVA) to handle uncertainty in mega projects under interval-valued fuzzy (IVF)-environment. Considering that uncertainty is very common i...

The proper display of transmembrane receptors on the leading edge of migrating cells and cell extensions is essential for their response to guidance cues. We previously discovered that MADD-4, which is an ADAMTSL secreted by motor neurons in Caenorhabditis elegans, interacts with an UNC-40/EVA-1 co-receptor complex on muscles to attract plasma membrane extensions called muscle arms. In nematode...

Improving methods for assessing the spatial and temporal resolution of organic compound concentrations in marine environments is important to the sustainable management of our coastal systems. Here we evaluate the use of ethylene vinyl acetate (EVA) as a candidate polymer for thin-film passive sampling in waters of marine environments. Log K(EVA-W) partition coefficients correlate well (r(2) = ...

In this paper, a Web-based learning environment developed within the project called Virtual Learning Spaces (EVA, in Spanish) is presented. The environment is composed of knowledge, collaboration, consulting and experimentation spaces as a collection of agents and conventional software components working over the knowledge domains. All user interfaces are Web pages, generated dynamically by ser...
