Hydractiniid hydroids display a range of morphological variation from sheet-like forms (i.e. closely spaced polyps with high rates of stolon branching) to runner-like forms (i.e. widely spaced polyps with low rates of stolon branching), thus exemplifying the patterns of heterochrony found in many colonial animals. A sheet-like and a runner-like inbred line of Podocoryne carnea were produced to ...

Nowadays, hydropower plays an essential role in the energy market. Due to their fast response and regulation capacity, hydraulic turbines operate at off-design conditions with a high number of starts and stops. In this situation, dynamic loads and stresses over the structure are high, registering some failures over time, especially in the runner. Therefore, it is important to know the dynamic r...

Fermented maize product, ogi, is a popular weaning and breakfast cereal in west coasts of Africa. In the study proximate, mineral and amino acid compositions of ogi from a composite mixture of white maize (Zea mays L.) and scarlet runner bean (Phaseolus coccineus L.) flours were evaluated using standard processing techniques. Maize ogi was substituted with scarlet runner bean flour at ratios of...

Pumped hydro energy storage (PHES) is currently the only proven large-scale energy storage technology. Frequent changes between pump and turbine operations pose significant challenges in the design of a pump-turbine runner with high efficiency and stability, especially for ultrahigh-head reversible pump-turbine runners. In the present paper, a multiobjective optimization design system is used t...

Plant products have been put to use in a variety of contexts ever since ancient times. The development chemical goods, on the other hand, led decline employment these methods against pests. Recently, there has rise concerns over public health and environmental security, which requires identification natural compounds that potential be utilized insect Mosquitoes are major transmitters illnesses ...

We analyze a model of fault-tolerant systems in a probabilistic setting, exemplified by a simple routing problem in networks. We introduce a randomized variant of a model called the “sabotage game”, where an agent, called “Runner”, and a probabilistic adversary, “Nature”, act in alternation. Runner generates a path from a given start vertex of the network, traversing one edge in each move, whil...

In WrightEagle2009, we continue to research based on the previous WrightEagle 2D soccer simulation team. WrightEagle has won the runner-up of RoboCup 2008 and Robocup 2007, the Champion of RoboCup 2006, and the runner-up of RoboCup 2005. In this paper, we mainly present the team structure of our new team WE2009, and the new techniques since the last competitions.

Selective breeding of house mice has been used to study the evolution of locomotor behavior. Our model consists of 4 replicate lines selectively bred for high voluntary wheel running (High-Runner) and 4 bred randomly (Control). The major changes in High-Runner lines appear to have taken place in the brain rather than in capacities for exercise. Their neurobiological profile resembles features o...
