Although, it is a legal practice in some countries, still it is a challenging and controversial practice in ethical and legal perspectives. It has been argued that based on the princ...
This paper presents investigation effects of a sharp edged gust on aeroelastic behavior and time-domain response of a typical section model using Jones approximate aerodynamics for pure plunging motion. Flutter analysis has been done by using p and p-k methods developed for presented finite-state aerodynamic model for a typical section model (airfoil). Introduction of gust analysis as a linear ...
OBJECTIVE To detect and explain changing trends in incidence, case fatality rates, and mortality for unintentional injuries in the Netherlands for the years 1950 through 1995. METHODS Using national registry data, the authors analyzed trends in traffic injuries, occupational injuries, and home and leisure injuries. RESULTS Between 1950 and 1970, mortality from unintentional injuries rose, r...
The relationship of the clavigerite genera Diartiger Sharp and Microdiartiger Sawada is discussed, and the synonymy of the two genera proposed by Besuchet (1986) is followed. This results in two new combinations: D. thinhi (Nomura), comb. n. and D. songxiaobini (Yin & Li), comb. n. Two new species, D. dentatus Yin & Li, sp. n. and D. yaoluopingensis Yin & Li, sp. n. are described from Anhui, Ea...
The effects of sodium bicarbonate concentration, population density, and temperature on the maintenance of an outdoor monoculture of the cyanobacterium Spirulina platensis were studied. A clear response by Spirulina to the concentration of bicarbonate was evident, with 0.2M bicarbonate representing the lowest concentration in which a monoculture could be maintained. When the temperatures fell d...
Four new species of the genus Thoracophorus Motschulsky, 1857 of the Neotropical region are described: T. verhaaghi n. sp., T. zicsii n. sp., T. struyvei n. sp., and T. perplexus n. sp. The new species originate from French Guiana, Peru, and Ecuador. Similar species T. filum Sharp, 1887, T. proximus Irmler, 1985, T. exilis (Erichson, 1840) and T. aequalis Sharp, 1887 are compared to discuss dif...
Recently, BMI screening in public schools has stirred sharp controversy with the emergence of letters sent home to parents indicating their child’s BMI percentile and weight category. In Massachusetts, these letters have been deemed, “fat letters,” and have appeared on late night comedy shows, newspapers, and televised news reports. Not only has screening come under harsh criticism, but the inc...
the skill of reading in english as a foreign language is an important and challenging one which is affected both by linguistic and extra linguistic factors. since vocabularies are part and parcel of every reading comprehension text, knowing enough vocabulary always facilitates this process. however, guessing strategy as one of the most important strategies has consistently ignored by language l...
in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
