The evolution of a submarine landslide is very complicated process due to slurry–water interactions. Most previous studies have focused on debris flows or turbidity currents independently. Little research has been conducted the processes transformation from into currents. Moreover, underlying mechanical mechanisms these are not well understood. In this study, we aimed better understand by simul...

Nowadays, one of the problems of human life is popula- tion congestion and the lack of ability to meet their needs. One of the important infrastructures affected by this issue is the transportation infrastructure. Moreover, increasing transportation facilities through conventional methods, due to the need for macro investment and much time, cannot be nowadays considered as a proper and practi- ...

Introduction: The H-chondrite parent asteroid provides the second-most abundant type of meteorites that currently reach Earth's surface [1]. These rocks recorded their parent asteroid's collisional history and melted H-chondrites chronicle the most severe cratering events. Samples and Methods: Seven samples of clast-rich impact melt rocks from the La Paz Icefield, Antarctica were analyzed in Pl...

We are interested in flows on general networks and derive a kinetic equation describing general production, social or transportation networks. Corresponding macroscopic transport equations for large time and homogenized behavior are obtained and studied numerically. This work continues a recent discussion [20] and provides additionally explicit equilibrium solutions, second–order macroscopic ap...

In The New Science of Cities , Michael Batty suggests that to understand cities we must view them not simply as places in space but as systems of networks and flows. Drawing on the complexity sciences, social physics, urban economics, transportation theory, regional science, and urban geography, and building on his own previous work, Batty seeks to introduce theories and methods that reveal the...

Since the use of PEG-coated pellets for the first oral sustainedrelease formulation in 1952, coated pellets have been used extensively to control the drug release kinetics. The term “pellet” has been used interchangeably with other terms, such as bead, sphere, granule, and particle. A large number of drug products have been available to patients. Despite extensive use of the coated pellets, the...

the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...

With the growing demand for air transportation and the limited ability to increase capacity at key points in the air transportation system, there are concerns that, in the future, the system will not scale to meet demand. This situation will result in the generation and the propagation of delays throughout the system, impacting passengers’ quality of travel and more broadly the economy. There i...

We investigate the traffic flows of the Korean highway system, which contains both public and private transportation information. We find that the traffic flow Tij between city i and j forms a gravity model, the metaphor of physical gravity as described in Newton’s law of gravity, PiPj/r 2 ij , where Pi represents the population of city i and rij the distance between cities i and j. It is also ...
