Marine reserves are becoming progressively more important as anthropogenic impacts continue to increase, but we have little baseline information for most marine environments. In this study, we focus on the Oceanic Shoals Commonwealth Marine Reserve (CMR) in northern Australia, particularly the carbonate banks and terraces of the Sahul Shelf and Van Diemen Rise which have been designated a Key E...

In this paper, we study the Menger property on a class of hypercube-like networks. We show that in all n-dimensional hypercubelike networks with n − 2 vertices removed, every pair of unremoved vertices u and v are connected by min{deg(u),deg(v)} vertex-disjoint paths, where deg(u) and deg(v) are the remaining degree of vertices u and v, respectively. Furthermore, under the restricted condition ...

We study subgroups of Z which possess group theoretic properties analogous to properties introduced by Menger (1924), Hurewicz (1925), Rothberger (1938), and Scheepers (1996). The studied properties were introduced independently by Kočinac and Okunev. We obtain purely combinatorial characterizations of these properties, and combine them with other techniques to solve several questions of Babink...

This is a paper based on author’s lectures delivered at the 2005 Clay Mathematics Institute summer school at MSRI. It serves as an overview on the Kähler-Ricci flow over complete noncompact manifolds.

Data cube is the core operator in data warehousing and OLAP. Its efficient computation, maintenance, and utilization for query answering and advanced analysis have been the subjects of numerous studies. However, for many applications, the huge size of the data cube limits its applicability as a means for semantic exploration by the user. Recently, we have developed a systematic approach to achi...

INFLUENCES OF THE LOGGERHEAD SPONGE (SPHECIOSPONGIA VESPARIUM) AND THE VASE SPONGE (IRCINIA CAMPANA) ON NEARSHORE HARDBOTTOM COMMUNITY DEVELOPMENT IN THE FLORIDA KEYS Scott Donahue Old Dominion University, 2008 Director: Dr. Mark J. Butler IV Sponges, octocorals, and stony corals are the dominant sessile fauna within shallow, hard-bottom communities in the Florida Keys, FL (USA). The sponge com...

this experiment were carried out to compare different short-term oestrous synchronization methods in farahani ewes to determine of the best method, so were used 123 ewes from a herd in delijan city in markazi province. after ensuring their health, ewes were divided  to five experimental groups randomizely. the oestrous cycles of the ewes were synchronized using these five methods: 1) use of cid...

To meet the needs of sponge city construction, based on design method mix proportion green porous ecological concrete, engineering performance concrete was studied with orthogonal experimental. The results show that compressive strength specimens peaked at 0.9% admixture sponge; optimal sponge, 12% mineral powder; compared ordinary water-retaining property is twice than ordinary, and has high p...

Heterotrophic bacteria associated with the Caribbean sclerosponge, Ceratoporella nicholsoni (Hickson), were found to occur extracellularly and were confined to the mesohyl regions of the sponge tissue. Physiological, metabolic, and morphological attributes of the culturable bacteria associated with the sponge were recorded by using numerical taxonomy methods for the analysis of 158 phenotypic a...
