Abstract The fatigue behavior of plain concrete has been studied for decades, usually under compressive or tensile loading. Shear loading (mode II) almost completely neglected in the past. In contrast to cylindrical compression tests, this type offers advantage precise load determination and a small, well-defined fracture surface. This paper presents comprehensive experimental campaign 66 shear...

Male albino rats weighing between 150-225 gm fasted over night but freed having water ad libitum were used to assess the diuretic efficacy of intramuscular aminophylline and frusemide separately and concurrently after intraperitoneal 10 ml of distilled water loading. The normal rate of diuretic weight loss was less augmented by aminophylline and more augmented by frusemide. The diuretic respons...

We determine the inviscid dynamics of a point vortex in the vicinity of a flexible filament. For a wide range of filament bending rigidities, the filament is attracted to the point vortex, which generally moves tangentially to it. We find evidence that the point vortex collides with the filament at a critical time, with the separation distance tending to zero like a square root of temporal dist...

In this paper we consider concurrent execution of multiple data mining queries. If such data mining queries operate on similar parts of the database, then their overall I/O cost can be reduced by integrating their data retrieval operations. The integration requires that many data mining queries are present in memory at the same time. If the memory size is not sufficient to hold all the data min...

We report exceptional ductile behavior in individual double-walled and triple-walled carbon nanotubes at temperatures above 2000 degrees C, with tensile elongation of 190% and diameter reduction of 90%, during in situ tensile-loading experiments conducted inside a high-resolution transmission electron microscope. Concurrent atomic-scale microstructure observations reveal that the superelongatio...

Current computational methods for simulating locomotion have primarily used muscle-driven multibody dynamics, in which neuromuscular control is optimized. Such simulations generally represent joints and soft tissue as simple kinematic or elastic elements for computational efficiency. These assumptions limit application in studies such as ligament injury or osteoarthritis, where local tissue loa...

Multimedia transmission in wireless networks requires high quality of service in terms of packet error rate (PER), throughput and packet delay. InterSector/Intra-Sector Scheduling (ISISS) has been proposed [1] to use basestations coordination in packet scheduling to reduce PER by avoiding (minimizing) concurrent transmission of potential cochannel interferers. Since ARQ schemes can also be used...

BACKGROUND Control of the onset of DNA synthesis in mammalian cells requires the coordinated assembly and activation of the pre-Replication Complex. In order to understand the regulatory events controlling preRC dynamics, we have investigated how the timing of preRC assembly relates temporally to other biochemical events governing progress into S-phase. METHODOLOGY/PRINCIPAL FINDING In murine...
