MUSCULAR CONTRACTIONS LEAD to a large (2) and rapid (14) increase in muscle perfusion, providing a challenging field of research for over a century. A particular challenge has been deciphering the mechanism(s) that regulate the increase in vascular conductance that, in turn, enables the large change in muscle perfusion. To further complicate the problem, the mechanism(s) regulating blood flow c...

The active imperative sentences often tend to sound harsh. sentence has a commanding meaning and ends with an exclamation mark. In the Indonesian language, be more polite, uses word politeness different structure. These polite are called passive sentences. Changing can done mathematically through several stages. stages determining set of word, types, using binary operations obtain rules for cha...

In the torpedo attack, appropriate firing distance is key to ensure hit target, it’s necessary used within maximum distance. Therefore, under premise of known conditions, determine and be familiar with factors that affect value influencing rules each factor. Based on model acoustic homing torpedo, expression established, main affecting are obtained. Through simulation, influence analyzed quanti...

The benefits associated with structural control include the mitigation of undesired structural responses and reduction in the probability of damage to structural components during seismic events. Structural control systems in current use depend on extensive wired communication systems to connect sensors and actuators with a centralized controller. While wired architectures are appropriate when ...

A new method to design in-orbit synthetic aperture radar operational parameters has been implemented for the Korean Multi-purpose Satellite 6 mission. The optimizes pulse repetition frequency when a satellite altitude changes from its nominal one, so it advantage that performances can satisfy requirements operation. Other commanding have designed conduct trade-off between those parameters. This...

There is an increasing desire in many organizations, including NASA and the DoD, to use constellations or fleets of autonomous spacecraft working together to accomplish complex mission objectives. At the Air Force Research Laboratory’s (AFRL) Space Vehicles Directorate we are investigating and developing architectures for commanding and controlling a cluster of cooperating satellites. For many ...

in this paper we study right $n$-engel group elements‎. ‎by modifying a group constructed by newman and nickel‎, ‎we construct‎, ‎for each integer $ngeq 5$‎, ‎a 2-generator group $g =langle a‎, ‎brangle$ with the property that $b$ is a right $n$-engel‎ ‎element but where $[b^k,_n a]$ is of infinite order when $knotin {0‎, ‎1}$‎.

introduction the eustachian valve (ev) remnant, when present in adults, is usually rudimentary. however, in echocardiographic examinations, it may appear as a mobile long structure in the right atrium, and it rarely protrudes into the right ventricle. when it is quite large, the ev remnant could be misdiagnosed as a right atrial tumor, thrombus, or vegetation. case presentation an 83-year-old p...
