This research presents the benefits of GeoGebra for development skills with Geometry topics in 9th year Elementary School final years, an attempt to minimize deficit teaching geometric contents. The this was based on and competences National Common Curricular Base, challenges proposals being elaborated software demonstrate contents their applications a more concrete way. As application is inter...

In the United States, eradication of persistent federal deficits has won broad bipartisan support. At the same time, political pressures have mounted to strengthen the Federal Reserve's explicit concern with price stability. Proposals under consideration would require a much narrower focus on the part of Fed policymakers, and could be interpreted as targeting the price level rather than a negli...

Abstract The development of modern power systems is accompanied by the problem inertia deficit, and there an urgent need to evaluate system level. Especially, accurate estimation load-side level extremely important. Based on comprehensive statistics, a method proposed. Starting from analysis base elements, expressions for under various operation modes are given based modeling basic load units; ...

When dsDNA polymers containing identical number of base pairs were electrophoresed through a nanopore in a voltage biased silicon nitride membrane, the measured time integral of blocked ionic current (the event-charge-deficit, ecd, Fologea, D., Gershow, M., Ledden, B., McNabb, D. S. et al.., Nano Lett. 2005, 5, 1905-1909) for each translocation event was the same regardless of whether the molec...

in order to investigate the effect of hexaconazole (hex) on the increasing tolerance to water deficit stress of two soybean (glycine max l.) cultivars, an experiment was conducted in faculty of agronomy of tarbiat modares university as factorial experiment in randomized complete block design arrangement. factors examined in this study were included soybean cultivars (l17 and clark63), hex conce...

During winter, trees have to cope with harsh conditions, including extreme freeze-thaw stress. This study focused on ice nucleation and propagation, related water shifts and xylem cavitation, as well as cell damage and was based on in situ monitoring of xylem (thermocouples) and surface temperatures (infrared imaging), ultrasonic emissions, and dendrometer analysis. Field experiments during lat...

Recovery of gold from copper-rich ores has proved challenging. Dissolved copper in cyanide-deficit leach solutions severely interferes with adsorption resulting low recoveries onto activated carbon or ion exchange resins. This study reports the efficiency different adsorbents for selective recovery copper-containing cyanide leachate. Activated (NORIT GAC 1240), mixed base (Purogold A193), stron...
