[1] Recurrence times for extreme drought events in the African Sahel are estimated using a classical peaks-overthreshold model. Results, which are computed for both mean seasonal rainfall and fractional area in drought, suggest that the distribution of dry extremes after about 1970 is statistically distinct from that of preceding years. This finding throws into relief the critical role played b...

Mixter and Barr (20) have first established the relationship between disc herniation and sciatica in 1934 (20). Yasargil (36) and Caspar (4) have pioneered the minimally invasive lumbar disc surgery by using surgical microscope and developing microinstruments in the 1970’s. Hijikata has performed the first percutaneous discectomy in 1975. Kambin (17) has first used an arthroscope for discectomy...

cam (complementary and alternative medicine) therapies have become increasingly  popular in pediatric populations. phytotherapy are the most common cam used in children. yet, little is known about children’s preferences for cam. but it is expected to become more widely integrated into the modern medical system, including the medical curriculum.the aim of this study is to introduce the prevalenc...

Erythrosine (FD&C Red No. 3) is widely used as a coloring agent for foods, beverages, pharmaceutical preparations, and cosmetics. It has been evaluated for acceptable daily intake by the Joint FAO/WHO Expert Committee on Food Additives (see Annex 1, Ref. Nos. 8, 19 & 35) in 1964, 1969 and 1974. At the 18th Meeting (1974) of the Committee, an ADI of 0 2.5 mg/kg body weight was allocated. Toxicol...

———. 1970. "Four Notion of Independence." Theoria no. 36:161-164. Reprinted in: Logic and metaphysics (1999) pp.127-130. WFour (binary) relations of independence I(p,q) between propositions are distinguished: the Wittgensteinian I sub-w, the statistical I sub-s, the modal I sub-m, and the deductive I sub-d. The validity of the following theorem is argued for: I sub-w(p,q) implies I sub-s(p,q) i...
