We analyse the excitation mechanisms which determine the dynamics of highly excited hydrogen atoms traversing a wavegulde. Experimental measurements to verify predictions denved from Floquet theory are suggested.

We report the roadkill of a jaguar in one of the longest highways in Brazil (BR-101), in the stretch where this road crosses one of the most important Atlantic Forest remnants in the country: the Linhares-Sooretama block. The jaguar population present in this area represents the very last in entire Espírito Santo state. There is an approved project to the lines duplication of the entire BR-101 ...

a general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. the robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. the curvatures in pipeline are the most important constraints in front of the robot through navigation process. to study the adapt...

Measurements of high pT hadrons at the Relativistic Heavy Ion Collider (RHIC) may provide insight into a quark gluon plasma (QGP) [1]. Since jets have to traverse the excited matter, their spectra should be changed in comparison with the elementary hadron-hadron data. The energy loss of jets has been proposed as a possible signal of the QGP phase in relativistic heavy ion collisions [2]. Over t...

By the latter eighteenth century, one may imagine a great arcing east-west trade-road, El Camino Real Nuevo (the New Royal Road), which served to define the Gulf South as a region and marked the historical limits of Spanish dominion in eastern North America in the century before Anglo-American expansionism. El Camino Real Nuevo, however, actually ran east-west rather than north-south. It served...

During the past century, fossil fuels--petroleum liquids, natural gas and coal--were the dominant source of world energy production. From 1950 to 2005, fossil fuels provided 85-93% of all energy production. All fossil fuels grew substantially during this period, their combined growth exceeding the increase in world population. This growth, however, was irregular, providing for rapidly growing p...

The authors contributing to this section have identified a number of strengths, struggles, and future directions for research in the broad area of pediatric oncology. In their paper, Armstrong and Reaman focus on the past, present, and future of multicenter cooperative groups, which, in the United States, have primarily culminated in the formation of the Children’s Oncology Group (COG). Last, G...

This study describes a new convenient and robust system developed to measure benthic boundary layer properties, with emphasis placed on the determination of bed shear stress and roughness height distribution within estuarine systems by using velocity measurements. This system consisted of a remotely operated motorised traverser that allowed a single ADV to collect data between 0 and 1 m above t...

Locomotion for legged robots poses considerable challenges when confronted by obstacles and adverse environments. Footstep planners are typically only designed for one mode of locomotion, but traversing unfavorable environments may require several forms of locomotion to be sequenced together, such as walking, crawling, and jumping. Multi-modal motion planners can be used to address some of thes...

Movement, or mobility, is key to the accessibility, design, and usability of many websites. While some peripheral mobility issues have been addressed few have centered on the mobility problems of visually impaired users. We use our past work to address these issues and derive mobility heuristics from mobility models, use these heuristics to place mobility objects within a web page, and describe...
