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 ...

The paper considers a numerical experiment with three groups of low-consuming inflow turbines partial blading the runner. Geometrical models turbine stages runner at different angles nozzle inclination have been developed. are investigated. efficiency and speed coefficient nozzles calculated. There has carried out modeling working fluid flow by using computational gas dynamics elements. Pick va...

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...

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.

Hydropower, a clean and renewable energy resource, has been developed worldwide for the economic development and improvement of people's living standards. It has also been used to improve the stability of the smart power grid. Depending on the water head of hydropower plants, various types of hydraulic turbines such as Francis, Kaplan and Pelton have been designed to maximize efficiency. Franci...

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...
