The core challenges associated with enterprise OLAP are how to structure the database and how to build a decision support architecture that allows for complex analysis and qualification. The primary components of an OLAP system – the database and the analysis engine – must be capable of handling large amounts of data in varying structures. Warehouses will continue to grow and contain data that ...

THIS distinctive book was published only six months ago, yet it has already won a definite place for itself as a well balanced and scholarly text which captures and holds the interest of the beginning student. Teachers like Fundamentals of Physical Science because of its completeness and balance of subject matter; the clarity of its explanations, especially in the more elementary material of ph...

In this review of the chemistry, biochemistry and chemical pathology of the bile pigments I am well aware that I shall ask many more questions than I am able to answer. It seems appropriate that the subject should be considered under the five headings: -Chemistry; Formation from Haem Proteins; Transport in the Blood; Conjugation and Transport to the Bile; and Changes in the Gut. I shall conclud...

Glutamate, as an essential neurotransmitter, has been thought to have different roles in the central nervous system (CNS), including nerve regeneration, synaptogenesis, and neurogenesis. Excessive glutamate causes an up-regulation of the multiple signaling pathways, including phosphoinositide-3 kinase/protein kinase B (PI3K/Akt), Akt/mammalian target of rapamycin (mTOR) protein, mitogen-activat...

We have shown recently that the temporal order of antioxidant consumption in human blood plasma exposed to a constant flux of aqueous peroxyl radicals is ascorbate = protein thiols greater than bilirubin greater than urate greater than alpha-tocopherol and that detectable lipid peroxidation starts only after ascorbate has been consumed completely. In this paper, we show that it is indeed ascorb...

We obtained new ROSAT HRI and optical observations in the field of the Einstein X-ray source E 0336–248, which we use to identify it as a 19th magnitude BL Lacertae object at z = 0.251 with LX = 1× 10 45 erg s. It is also a 14 mJy radio source at 20 cm. An emission-line galaxy at z = 0.043 that was previously considered a Seyfert identification for E 0336–248 is shown instead to be an unrelated...

Land acquisition and ownership is an important part of modern agriculture in North America. Given the unique nature of farmland as a good, this paper develops a multi-agent simulation of farmland auction markets in a Canadian context. The model is used to generate data on land transactions between farm agents to determine if a particular auction design or type is better suited to farmland trans...
