a fluid, which is stable under the action of buoyancy, can oscillate under the influence of buoyancy and coriolis forces. the resulting ageostrophic oscillations with a frequency between coriolis and buoyancy frequencies are called inertia-gravity waves, hereafter igws. in this study we investigate the generation and propagation of igws over iran. to this end, the weather research and forecasti...

performance optimization of chisel tine was proposed by using a chisel plow with adjustable rake angle. effective treatments consisted of soil moisture at 0.5, 0.7 and 0.9 of plastic limit (pl), three rake angle of 30, 40 and 50 degree and speeds of to 3, 5 and 7 km h-1. the measured parameters included draft, soil disturbance area, soil upheaving area, clod mean weight diameter (mwd), specific...

The problem of Knowledge Management (KM) is eminent in the P2P area. This paper presents a general framework of knowledge management based on web services in peer-to-peer (P2P) environment. P2P knowledge management yields significant advantages when combined and applied as web services for KM. By adopting web services techniques and distributed approaches, we partition the knowledge network int...

The natural evolution of any new area of consulting includes the appearance of methodologies for problem-solving. If Knowledge Management (KM) is the answer to questions about how to capture tacit knowledge, or accelerate innovation, or share knowledge, or resolve cultural incompatibilities in business processes, then this answer is not really operative until we can apply KM knowledge in such a...

At 16:16 local time (14:16 GMT) January 8, 2013 a moderate size earthquake ML5.8 (Mw5.7) occurred 40 km SE off the coasts of Limnos island, Northern Aegean, Greece. The epicenter coordinates were calculated to 39.636N 25.576E and the focal depth to 32.3 km (MT centroid depth 8 km) according to the Institute of Geodynamics, National Observatory of Athens (NOAIG). The earthquake was felt at a wid...

Historically, bobcats (Lynx rufus) were found throughout the Corn Belt region, but they nearly disappeared from this area due to habitat loss and unregulated harvest that occurred during the century after European settlement. Reports of bobcat occurrences have been increasing in Iowa, USA, and biologists would like to understand the mechanisms enabling bobcats to recolonize this fragmented agri...

AIM To evaluate female runners' pelvic floor muscles using three-dimensional ultrasonography (3DUS) and surface electromyography (SEMG). MATERIAL AND METHODS A cross-sectional study was conducted on 24 female runners. SEMG was performed using surface electrodes inserted in the vagina. 3DUS was performed using perineal convex transducer. SEMG was evaluated at rest and with maximum voluntary co...

Land, a non-renewable resource, is central to all primary production systems. The geospatial technology of Remote Sensing and GIS holds the potential for timely and cost – effective assessment of natural resources. The techniques have been used extensively in the tropics for generating valuable information about various surface features of the earth. Therefore, we have used Remote Sensing and G...

BACKGROUND Paired with satellite location telemetry, animal-borne instruments can collect spatiotemporal data describing the animal's movement and environment at a scale relevant to its behavior. Ecologists have developed methods for identifying the area(s) used by an animal (e.g., home range) and those used most intensely (utilization distribution) based on location data. However, few have ext...
