Search is among the most frequent activities on theWeb. However, the search activity still requires extraefforts in order to get satisfactory results. One of t hereasons is heterogeneous information resources andexponential increase of i nformation. The problem ofheterogeneity arises as result of di scipline specificlanguage used even in the domain specific documents...

The Effectiveness of the Enrichment Program in Sixth Grade Math and Science Classes A.Navidi, Ph.D. To improve students' learning in math and science enrichment programs have been introduced, yet their effectiveness has never been assessed. To this end, a large sample of administrators, teachers, and students were questioned and tested, while 46 class sessions were also observed. Over 400...

Lyubashenko has described enriched 2–categories as categories enriched over V–Cat, the 2–category of categories enriched over a symmetric monoidal V. This construction is the strict analogue for V–functors in V–Cat of Brian Day’s probicategories for V–modules in V–Mod. Here I generalize the strict version to enriched n–categories for k–fold monoidal V. The latter is defined as by Balteanu, Fied...

There are many processes that can transport gas from the galaxies to their environment and enrich the environment in this way with metals. These metal enrichment processes have a large influence on the evolution of both the galaxies and their environment. Various processes can contribute to the gas transfer: ram-pressure stripping , galactic winds, AGN outflows, galaxy-galaxy interactions and o...

Lyubashenko has described enriched 2–categories as categories enriched over V–Cat, the 2–category of categories enriched over a symmetric monoidal V. Here I generalize this to a k–fold monoidal V. The latter is defined as by Balteanu, Fiedorowicz, Schwänzl and Vogt but with the addition of making visible the coherent associators α. The symmetric case can easily be recovered. The introduction of...

Layers were fed diets with regular or 3 to 10 times more supplemental vitamins in an attempt to enrich eggs with these nutrients. Dietary concentrations of vitamins were chosen with the expectation of producing an egg with sufficient vitamins to achieve 50% of daily recommended intake (DRI). Eggs were assayed for all vitamins following a 90-d feeding period. There was considerable variation in ...
