tinere talente recrutate de profesorul Thoma Ionescu, a cărui intuiţie în alegerea colaboratorilor, viitorilor profesori de chirurgie, şefi de şcoală la rândul lor, nu a dat niciodată greş. Născut la 14 mai 1870 în oraşul Bârlad, acest fiu strălucit al pământului Moldovei, a reuşit prin calităţile sale înnăscute, dar mai ales printr-o muncă ordonată şi neobosită, să făurească o operă nepieritoa...

Iceberg C-18a (35 7 0.184 km) was studied repeatedly by five circumnavigational surveys in March-April 2009. During the period of the surveys, C-18a travelled 109 nautical miles in 23 days covering an area of 8.1 10 km. This iceberg was formed from iceberg C-18 (76 7 km) that originated from the Ross Ice Shelf in May, 2002. Ship-based measurements show that this iceberg produced fresh meltwater...

Many applications compute aggregate functions (such as COUNT, SUM) over an attribute (or set of attributes) to nd aggregate values above some speci ed threshold. We call such queries iceberg queries because the number of above-threshold results is often very small (the tip of an iceberg), relative to the large amount of input data (the iceberg). Such iceberg queries are common in many applicati...

Received Apr 10, 2017 Revised Sep 8, 2017 Accepted Sep 29, 2017 Aggregate function and iceberg queries are important and common in many applications of data warehouse because users are generally interested in looking for variance or unusual patterns. Normally, the nature of the queries to be executed on data warehouse are the queries with aggregate function followed by having clause, these type...

Nurses are often obliged to work in a 12-hr shift work system. We have decided to check whether such a working system constitutes an excessive load for nurses. On the basis of a questionnaire survey among nurses working in an 8-hr daytime shift system (169 nurses) and in a 12-hr shift (536 nurses), the amount of physical workload, work stress, and after-work activities were compared. Data analy...

IMPORTANT contributions to the understanding of autoimmune processes have come from studies on populations (Serafini, Torrigiani & Masala, 1964; Jacobs et aL, 1969; Whittingham et al., 1969a; Couchman, Wigley & Prior, 1970; Hooper et al., 1971) which have shown a substantial proportion of subjects, usually elderly, with serological stigmata of autoimmunity. The iceberg analogy of autoimmunity i...

The data storing and retrieving are playing a major role in the data clustering and data warehousing techniques. The effectiveness of a data retrieving method depends upon the data specific queries for retrieving the data from the database. Iceberg query is a unique class of aggregation query, which computes aggregate values above a given threshold. Many data mining queries are basically ice be...
