Abstract We present observations during the interval 2006–2014 of 27 day and 13.5 periodic oscillations in ionospheric sporadic E (Es) layer. This is a thin, dense layer composed metallic ions Earth’s upper atmosphere between 90 130 km. Lomb–Scargle spectral wavelet analyses reveal that these pronounced periodicities observed from ground-based ionosondes GPS/GNSS radio occultations are associat...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
From 2003 to 2008, 176,643 Gratiana boliviana Spaeth (Coleoptera: Chrysomelidae) were released in Florida as part of a biological control program targeting tropical soda apple (TSA) Solanum viarum Dunal (Solanaceae). The spatial distribution of releases was clustered with more beetles released in south/central Florida than further north. A survey conducted in the fall of 2008 found G. bolviana ...

according to general circulation model (gcm), zonal thermal belts are 1- inter-tropical convergence zones (itcz) around eqator; 2- sub tropical high (sth) belt around 30 degree latitude; 3- sub polar low (spl) belt around high latitudes. the belt of inter-tropical convergence zone (itcz) displaces in meridional path, about 5° over the oceans and up to 40° over continents, during the seasons of ...
We consider quantum gravity model with the squared curvature action. We construct lattice discretization of the model (both on hy-percubic and simplicial lattices) starting from its teleparallel equivalent. The resulting lattice models have the actions that are bounded from below while Einstein equations (without matter) appear in their classical limit.
rhetoric of the enterprise culture and present a more contextualized account of individuals' experience of entrepreneurship training/development. Vanessa Casanova, Auburn University Reforesting Alabama: Guest Workers in the Forest Industry Driving through rural, heavily forested areas of Alabama during the winter months, one may be surprised to find that small dilapidated motels, houses and tra...
SQL:2003, die neuste Version der SQL-Norm, sieht erstmals die Unterstützung von XMLDaten vor. Damit wird es möglich, Tabellen mit XML-wertigen Spalten anzulegen. Der vorliegende Beitrag geht der Frage nach, welche prinzipiellen Möglichkeiten es für die Übergabe von XML-Werten zwischen Datenbanksystem und Anwendungsprogrammen gibt. Da die Eignung dieser Möglichkeiten von den Charakteristika der ...
