Rhythmic movements are often controlled by systems containing coupled subnetworks whose oscillations are of different frequencies. We show how fast inhibition from the pyloric network interacts with a slow modulatory input to control the frequency of the gastric mill rhythm of the crustacean stomatogastric ganglion. We deduce that the timing of the pyloric input is crucial in determining what a...

Centrifugal pumps are considered to be less destructive to blood elements (1) when compared to roller pumps. However, their large prime volumes render them unsuitable as arterial pumps in heart lung machine (HLM) circuitry for children. In November of 2014, the circuit at Arnold Palmer Hospital, a Biomedicus BP-50 with kinetic assist venous drainage (KAVD) and 1/4″ tubing was converted to a rol...

This work presents improved technology for attaining high-quality rolled metal strip. The new technology is based on an innovative method to model both the static and dynamic characteristics of rolling mill deflection, and it applies equally to both cluster-type and non cluster-type rolling mill configurations. By effectively combining numerical Finite Element Analysis (FEA) with analytical sol...

Roller skis are used by cross-country skiers for snow-free training, with the aim of imitating skiing on snow. The roller skis on the market that are constructed for use in the classical style are equipped with a front and a back wheel, one of which has a ratchet to enable it to grip the surface when diagonal striding and kick double poling. A new type of roller ski was constructed with a funct...

compared to other methods of vaccine production, (e.g. culture flask and bioreactor system), the roller culture method for producing rabies vaccine is simpler, and the equipment easier to install and maintain, and also in the event of contamination of one roller, the entire batch need not be discarded. this system provides a much larger surface area than the culture flask, and also ensures a mu...

Rollers crimpers have been used in conservation agriculture to terminate cover crops; however, excessive vibration generated by the original straight-bar roller design has delayed adoption of this technology in the United States. To avoid excessive vibration, producers generally reduce operating speeds that increase the time needed to perform the field operation. The objectives of this research...

Received: 20 October 2014 / Accepted: 15 November 2014 Abstract: An approach for determination of the best cutting parameters leading to maximum material removal rate in machining D2 (Die Steel) on vertical milling centre is used. The Response Surface Methodology technique is applied to obtain optimum values of considered parameters in machining D2 (Die Steel) with four flutes carbide end mill ...

OBJECTIVE To describe the circumstances, severity, and outcomes of skating-related injuries among children admitted to trauma centers. DESIGN A cross-sectional comparison of roller skaters (n = 154), in-line skaters (n = 190), and skateboarders (n = 254) aged 5 to 19 years who were hospitalized with injuries. SETTING Seventy-nine hospitals and pediatric trauma centers participating in the N...
