One of the characteristics of the modern international systems is the undeniable role the new communication technologies play in different sections of human societies. Modern communication technologies such as satellites and computers have challenged the national authority and sovereignty of Vestfallian states.  Although national states, specially, in the third world countries, extremely resist...

Several new experimental concepts in high-energy particle physics have been proposed recent years. The physical goals include precisely measuring the properties of particles such as Higgs, Z and W, even looking for signs at future colliders. To meet evolving requirements track detector, Time Projection Chamber (TPC) detector prototype integrated with a UV laser system was developed main Circula...

The highly variable timing of streamflow in snowmelt-dominated basins across western North America is an important consequence, and indicator, of climate fluctuations. Changes in the timing of snowmeltderived streamflow from 1948 to 2002 were investigated in a network of 302 western North America gauges by examining the center of mass for flow, spring pulse onset dates, and seasonal fractional ...

Multi-object tracking has been recently approached with the min-cost network flow optimization techniques. Such methods simultaneously resolve multiple object tracks in a video and enable modeling of dependencies among tracks. Min-cost network flow methods also fit well within the “tracking-by-detection” paradigm where object trajectories are obtained by connecting per-frame outputs of an objec...

Fission tracks with a range 19% longer than tracks produced by uranium fission fragments were observed on mylar foils after a three year underground (100 m w. e.) exposure to 3600 cm2 of radlogemc lead. Ordinary lead which was simultaneously exposed to mylar foils under the same conditions yielded a background effect of only 3% of the effect from radiogenic lead. The observed long-range tracks ...

Artificial intelligence courses at universities that do not have focused AI tracks may suffer from a lack of student interest unless they are tied to some application of AI that students find appealing. Robots have been used successfully to draw students into AI courses, but their use can take time away from material that instructors feel should be covered in a general course. We present an app...

Francisella tularensis is a gram-negative facultative intracellular bacterium that resists harsh environments. Several outbreaks of tularemia are linked to the consumption and contact with spring water. The number F. in some waters high, while others, this does not survive. Except organic compounds, metals could be important for survival Some strains showed association amoeba, which may act as ...

ABSTRACT Background: and soils with which it comes in contact. There is dual exposure from radon in water i.e. due toinhalation of the radon released from the water into the ambient air and through ingestion whenwater is used for drinking. As radon contaminated water adversely affects the health, it istherefore fundamental from health and hygiene point of view to measure radium concentrationand...

potato (solanum tuberosum l.) cultivation in two different climates causes difference in its growth process.the most frequently used indicators of growth for plants are the tuber growth rate (tgr), crop growth rate (cgr) and leaf area index (lai). shoot dry weight is the easiest, quickest and least costly component to measure the competitive features of plants.the results of some studies showed...
