There is a paucity of data concerning the changes in circulation occurring during swimming in fish. Data reported in the literature have been obtained from either restrained, anaesthetized or operated fish (Greene, 1904; Hart, 1945; Johansen, 1962; Robertson et al. 1966). Such procedures can have marked effects on fish (Fry, 1957). It is therefore surprising that little attention has been direc...

Johansen and Sornette proposes that the crash has fundamentally an endogenous origin and exogenous shocks only serve as triggering factors. This endogenous force is shown in price as power law log-periodicity (PLLP) signature prior to a crash. We estimate the highly nonlinear model developed by them using a hybrid approach which combines scatter search, genetic adaptor and tabu search. The mode...

This study estimates the effects of human capital underutilization on economic growth and productivity. paper investigated relationship between using a variety econometric tests like Augmented Dickey Fuller test, Johansen Integration ARDL model. The results indicate that, there is negative growth. that has greater long-term impact than it does in short run. Reforms to education training systems...

The feet of birds are important in the regulation of core temperature (Kahl 1963, Steen and Steen 1965, Johansen and Millard 1973) and are particularly effective in heat transfer when birds are normoor hyperthennic (Steen and Steen 1965). Under natural conditions, they must also be sites of considerable heat loss when they are immersed in cold water or in contact with cold substrates (e.g., ice...

This paper examines the relationship between stock returns and inflation. We focus on various econometric techniques to test this relationship, using monthly values of the Athens Stock Exchange Price index and the Greek Consumer Price index over the period 1988-2002. The results from a simple OLS model show evidence of a positive but not significant relationship, while when we consider a system...

This paper describes a technical security analysis which is based on experiments done in a laboratory and verified in a physician’s practice. The health care telematics infrastructure in Germany stipulates every physician and every patient to automatically be given an electronic health smart card (for patients) and a corresponding health professional card (for health care providers). We analyze...

Adults and immatures of Diaphorina teucrii sp. nov. (Hemiptera, Liviidae, Euphyllurinae) and adults of Tamarixia dorchinae sp. nov. (Hymenoptera, Eulophidae, Tetrastichinae) from Israel are described, diagnosed and illustrated. D. teucrii sp. nov. develops on Teucrium capitatum (Lamiaceae), representing a family which was previously not recorded as a psyllid host from Israel, and is parasitised...
