Well aligned and highly efficient field emission (FE) results have been obtained with regular arrays of gold nanowire (NW) patches [1]. However, strong variations of the maximum current Imax among single Au-NW patches have been attributed to contact problems between wires and substrate [2]. Recently we have focused our research in finding a systematic correlation between FE properties and morph...
identification of rapid degradation of ecological resources requires effective environmental monitoring including ecological integrity assessment .our first aim is to analyze ecological integrity in a landscape context while developing a method to assess integrity in spite of a dearth of historical data. we used a spatial-temporal reference framework for land cover maps for assessing ecologica...
Two aspects of patch geometry—area and isolation—currently dominate the field of metapopulation dynamics. Under this area-and-isolation paradigm, models commonly assume that the probability of local extinction decreases as patch area increases and that the probability of colonization increases as patch connectivity increases. Environmental variables other than patch area and isolation are assum...
There are many local fragmentation metrics, but most can be grouped into four types (composition/area, isolation, edge, and shape), none of them alone determines the degree a patch. Here, we together main metrics (area, shape, isolation) in order to propose new metric/index, Patch Fragmentation Index (PFI), with which determine at patch scale. The index was subsequently verified Ecuadorian seas...
Macro-reentrant ventricular tachycardia (VT) developed in a 20-year-old man, 17 years after surgical repair of tetralogy of Fallot. Activation mapping of the VT revealed its counterclockwise propagation around the right ventricle, and through a critical pathway between a transannular patch and the tricuspid annulus. This critical pathway was 6 cm long and contained myocardium with a normal ampl...
The accuracy of transcutaneous bilirubin (TcB) measurements obtained with a Bilicheck device in 70 preterm neonates before phototherapy and during phototherapy from the exposed and unexposed skin of the forehead (under the eye patch) was evaluated by comparing the TcB with the total serum bilirubin (TSB) that was performed within +/- 30 minutes of the TcB measurements. The correlation and propo...
The design and performance of a circularly polarized microstrip patch antenna, for the application in Wireless Local Area Network (WLAN), are reported here. The antenna is a proximity coupled microstrip patch antenna where the radiating patch is loaded by a V-slot. This miniaturized microstrip antenna has wide bandwidth in the frequency band of WLAN and exhibits circularly polarized far field w...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
