MACKEY (1955), working in Dar-es-Salaam, Tanganyika, found the house lizard population to be heavily infected with salmonella organisms. Out of 301 lizards investigated by him from 1943 to 1953 he recovered salmonellre from 144, giving the high figure of 48 per cent positive isolations. Two new types, Salmonella mgulani and S. lindi, were found. During 1956 an investigation of the types of salm...

This paper is concerned with the maximum that can be achieved in clinical trials using optimal methodologies if such exist, i.e., with strategy and not tactics. It might be thought that strategy so defined is too vague and too general to be fruitfully discussed, but I hope to convince you of the contrary. Considerations of strategy will involve us in controversial questions about the foundation...

The oldest rocks within the Kachchh Basin belong to the sediments of Kaladongar Formation exposed in Kuar Bet, Pachchham Island (western India). The Formation’s lowest unit, the Dingi Hill Member has yielded a moderately diversified calcareous nannofossil assemblage that includes the marker species of Lotharingius contractus and Triscutum sullivanii of late Early Aalenian age associated with re...

June 2014 | SportsTurf 11 This year we have purchased a Woods seeder that we will use to renovate the center of the field throughout the season. The combination of all of these things is what allows us to provide the best surface possible on a tight budget. Post-game repairs and rest are what really holds the field together from week to week. In the beginning of the season when it is hot, we wi...

The identification of orientation relationships (ORs) plays a crucial role in the understanding of solid phase transformations. In steels, the most common models of ORs are the ones by Nishiyama-Wassermann (NW) and Kurdjumov-Sachs (KS). The defining feature of these and other OR models is the matching of directions and planes in the parent face-centred cubic γ phase to ones in the product body-...

are known as guttate ophttalmicae or HassallHenle's warts.2 Arthur Hill Hassall (fig 1) was born in Teddington, Middlesex, England on 13 December 1817. He was the youngest of five children ofThomas and Ann Hassall.3 Influenced perhaps by his grandfather, father, and elder brother, who all were doctors, Hassall studied medicine in Ireland. He received his first diploma (in midwifery) in 1837 fro...

This paper presents a new method to correct for measurement error in wage data and applies this method to address an old question. How much downward wage flexibility is there in the U.S? We apply standard methods developed by Bai and Perron (1998b) to identify structural breaks in time series data. Applying these methods to wage histories allows us to identify when each person experienced a cha...
