north-western iran comprises diverse geographical landscapes, including pastures of piedmonts, mountains, and well-watered plains. the present chronology of this region, nevertheless, is based exclusively on data collected from sites around the urmia lake, other regions being almost totally ignored. during the late bronze age (hereafter lba) a new way of life took shape in the mountainous regio...

BACKGROUND The purpose of this study was to investigate whether there is a bi-directional relationship between sleep characteristics (time in bed, sleep duration, sleep chronology, and sleep efficiency) and time spent participating in outdoor active play among children. METHODS Participants consisted of 433 children aged 10-13 years from Kingston, ON, Canada. Time in bed, sleep duration, slee...

Currently a new version of the distance education platform WeLearn [3] to be combined with an agent system ([1], also developed locally) for providing advanced services [2] is under development. In a previous stage of the project software was created to automatically derive keywords from documents, either from the different versions of metadata already contained (various Microsoft file formats,...

As our ability to store information increases, the mechanisms we employ to access that information become ever more important. In this paper, we present Archosum, a prototype of an organizational system that attempts to encapsulate the benefits of both hierarchical and keyword systems. By introducing abstract entities, Archosum provides a simple interface with which users can build and maintain...

Tree-ring data from Chamaecyparis lawsoniana (A. Murr.) Parl. (Port Orford cedar; Cupressaceae) were used to create a standardized chronology, assess the local, limiting factors on radial growth, and investigate the extent of a unique climatic event. We produced a 580-year tree-ring chronology (A.D. 1420 to 2000) from a large number of cedars (n 5 1537) sampled in one 37 km2 area in the Siskiyo...

Understanding the geographic range and growth of species is essential for effective land management in a landscape affected by anthropogenic activity and climate change. Climate change is expected to alter the distribution and growth of many tree species in eastern North America, including northern white cedar (Thuja occidentalis L.). This research examined the effects of climate on radial grow...

Radiation recall presents as an acute inflammatory reaction triggered by systemic therapy, usually chemotherapy, and is typically limited to area that was previously irradiated. reactions are generally self-limiting most commonly occur in the skin. Many agents have been described elicit a radiation reaction, but exact pathogenesis largely unknown. Here, we describe first reported case of dermat...
