Freshwater mussels are found in dense, multi-species aggregations where the potential for resource partitioning should be high. One means by which mussels may be partitioning resources is through feeding on different food items. We compared gill morphology in four species of co-occurring freshwater mussels. We found differences in total gill surface area, density of latero-frontal cirri and the...

Suppose that the integers are assigned i.i.d. random variables f! x g (taking values in the unit interval), which serve as an environment. This environment deenes a random walk fX k g (called a RWRE) which, when at x, moves one step to the right with probability ! x , and one step to the left with probability 1 ? ! x. Solomon (1975) determined the almost-sure asymptotic speed (=rate of escape) ...

New species of the rarely encountered megachilid genera Afroheriades Peters from South Africa, Afroheriades hyalinussp. n., and Noteriades Cockerell from Myanmar and Thailand, Noteriades jenniferaesp. n. and Noteriades spinosussp. n., are described and illustrated. The species are described to make their names available for forthcoming publications on phylogenetic studies of the family Megachil...

This paper will examine Bakhtin’s theory that a genre’s unity is defined by its chronotope [Bakhtin, M. M. (1981). Forms of time and of the chronotope in the novel. In M. Holquist (Ed.), The dialogic imagination: Four essays (pp. 84–258). Austin: University of Texas Press] and assume that, if this is true, the rhetorical unity within a specific genre could also be defined by its chronotope. Cen...

Present distribution and economic potential According to FAO statistics there are about 19 million camels in the world, of which 15 million are found in Africa and 4 million in Asia. Of this estimated world population, 17 million are believed to be one-humped dromedary camels (Camelus dromedarius) and 2 millions two-humped (Camelus bactrianus). Approximately 11 million dromedaries, representing...

Introduction One of the important tasks of nurses in intensive care unit is interpretation of ECG. The use of training simulator is a new paradigm in the age of computers. This study was performed to evaluate the impact of cardiac arrhythmias simulator software on nurses' learning in the subspecialty Vali-Asr Hospital in 2016. Methods This study was conducted by quasi-experimental randomized ...

A new species of Paracooperia Travassos, 1935 was found in the small intestines of 4 bushbuck, Tragelaphus scriptus (Pallas, 1766), and 3 greater kudu, Tragelaphus strepsiceros (Pallas, 1766), all culled in the Kruger National Park. The nematodes appear to be widespread in the Park, since the bushbuck originated from Skukuza in the central part of the Park, 2 of the 3 kudu from near Malelane in...

Observers of contemporary politics know that Islamic extremism presents ‘the West’ with a serious challenge of national and international security consequent to terrorist events of recent time. In addition to constabulary and military responses, there remains the more fundamental question about how to understand Islamist ideology and how counternarratives might be framed in the interest of law ...
