In this paper, we describe the formatting guidelines for ACM SIG Proceedings. Knowledge discovery is the process of analysing data for future planning. The nature of data and anomalies are different in different record data sets. The problem of detecting contextual anomalies in data sets is also different from the traditional anomaly detection problem. A time series is a chronological sequence ...

Abstract For solitary bees, nesting substrate availability may limit population growth. Here, we investigate the of a locally abundant bee Osmia conjuncta Cresson (Hymenoptera: Megachilidae) in empty shells exotic snails, Cepaea spp. Held (Stylommatophora: Helicidae), Hamilton, Ontario, Canada. A literature review determined that O. was sparsely distributed throughout its range, with low relati...

Web 2.0 technologies such as wikis, podcasts/vodcasting, blogs and semantic portals could be quite effective tools in e-learning for health professionals. If effectively deployed, such tools can offer a way to enhance students', clinicians' and patients' learning experiences, and deepens levels of learners' engagement and collaboration within medical learning environments. However, Web 2.0 requ...

This study investigated the copulatory behaviour of the lumbricid earthworm Eisenia fetida (Savigny, 1826) in a natural population, and the uniparental reproduction of E. fetida and E. andrei Bouché 1972, two closely-related species. Sperm transfer occurred in 61 % of the matings observed, of which 88.2 % showed bi-directional sperm transfer, 9.8 % unidirectional sperm transfer and one earthwor...

Motivated by hydrodynamic simulations, we discuss the X-ray appearance of radio galaxies embedded in the intracluster medium (ICM) of a galaxy cluster. We distinguish three regimes. In the early life of a powerful source, the entire radio cocoon is expanding supersonically and hence drives a strong shock into the ICM. Eventually, the sides of the cocoon become subsonic and the ICM is disturbed ...

An extensive search for distant Giant radio galaxies on the southern hemisphere is justified. We emphasize the crucial role of optical spectroscopy in determination of their basic physical parameters, i.e. the distance, projected linear size, volume of their lobes or cocoon, luminosity, etc., and argue that SALT will be the best instrument for such a task.
