Turbidity and suspended-sediment changes from stream-crossing construction on a forest haul road in West Virginia, USA" (2013). USDA Forest Service / UNL Faculty Publications. Paper 247. A forested headwater watershed in West Virginia was monitored to examine changes to in-stream turbidity following the construction of a 0.92 km (0.57 mi) haul road. Due to the design of the study, most of the s...

the crossing number of a graph  is the minimum number of edge crossings over all possible drawings of  in a plane. the crossing number is an important measure of the non-planarity of a graph, with applications in discrete and computational geometry and vlsi circuit design. in this paper we introduce vertex centered crossing number and study the same for maximal planar graph.

This Study aims at throwing light on Islamic Civilization in the country of Andalusia as one crossing roads to Europe end Middle Ages through which took their sciences, knowledge and ingredients renaissance.Andalusia played an important role because its location broods between state wails who encouraged science consider scientists rights for about eight centuries transmitting west.

The Mediterranean Sea is known as an ecological barrier for numerous migratory birds flying from European breeding grounds to African wintering sites. Birds generally avoid migration over open sea and fly over land. In the Mediterranean Basin, few land bridges or bottlenecks for migratory birds exist. The narrowest are at the western and eastern extremes: the Strait of Gibraltar and Israel. Com...

Two different types of sex chromosomes, XX/XY and ZZ/ZW, exist in the Japanese frog Rana rugosa. They are separated in two local forms that share a common origin in hybridization between the other two forms (West Japan and Kanto) with male heterogametic sex determination and homomorphic sex chromosomes. In this study, to find out how the different types of sex chromosomes differentiated, partic...

Songbird populations are in decline all over the world, and our understanding of causal mechanisms remains surprisingly limited. It is important to identify extent individual variations migratory behaviour better understand species' ability respond environmental change. We describe annual British breeding European Pied Flycatchers Ficedula hypoleuca by using light-recording geolocators. During ...
