Regular path queries (RPQs) have quickly become a staple to explore graph databases. SPARQL 1.1 includes prop- erty paths, and so now encompasses RPQs as a fragment. Despite the extreme utility of RPQs, it can be exceedingly difficult for even experts to formulate such queries. It is next to impossible for non-experts to formulate such path queries. As such, several visual query systems (VQSs) have been proposed which simplify the task of constructing path queries by directly manipulating visual objects representing the domain elements. The queries generated by VQSs may, however, have many commonalities that can be exploited to optimize globally. We introduce Tasweet, a framework for optimizing “disjunctive” path queries, which detects the commonalities among the queries to find a globally opti- mized execution plan over the plan spaces of the constituent RPQs. Our results show savings in edge-walks / time-to- completion of 59%.

A 6-week feeding trial was conducted to evaluate the effect of dietary supplementation of Anionic Alkali Mineral Complex (AAMC) on growth performance, feed utilization, innate immunity, and disease resistance of L. vannamei. Graded levels of AAMC solution were included in a basal diet; 0% (Control), 0.05%, 0.1%, 0.2% and 0.4%. Shrimp fed diets supplemented with 0.2% and 0.4% AAMC had the highest growth performance, and compared to the control treatment, final body weight and specific growth rates were significantly higher (P<0.05). Feed utilization also improved significantly with AAMC supplementation. Non-specific immune responses of shrimp were significantly affected by dietary supplementation of AAMC; total hemocyte count of shrimp fed 0.1% and 0.2% diets was significantly higher the control diet shrimp group. Phenoloxidase and lysozyme activity was significantly higher in shrimp fed 0.2% diet compared to the control diet group. Glutathione peroxidase activity was significantly enhanced with dietary supplementation of 0.1%–0.2% AAMC. In a challenge test with Vibrio harveyi, shrimp fed 0.2% AAMC disease resistance was significantly higher than in shrimp fed the control diet. Overall, the results indicate that dietary supplement of AAMC improved growth, diet utilization, innate immunity, and disease resistance of Pacific white shrimp and approximately 0.2% in diets appeared to be the optimum supplemental level.
