Has Tom spoken truly? Surely, Jones’s epistemic position seems good enough for satisfying the predicate ‘knows that the animals in the pen are zebras’ (henceforth ‘knows Z’): Jones has visual experiences of a black and white striped horse-like animal, she can discriminate reliably between zebras and antelopes, she has read the sign on the pen that reads ‘Zebra Pen’, etc. Thus, Tom’s utterance o...

The previous paper (Horridge, 1966) showed that a crab gives a directional eyestalk response to a striped drum which has been moved during a dark period. The crab's ability to do this shows that the former position of the stripes is remembered in some way for many minutes in the dark and is correlated with the new position on reillumination. In that paper two aspects were omitted for simplicity...

This species superficially resembles Scaptodrosophila paratriangulata (Gupta, 1971) in having cross striped abdominal tergites, apically rounded wing, ocellar triangle brownish black, heel of the genital arch not pointed and the row of teeth of surstylus not convexed. However, this species distinctly differs from S. paratriangulata in having dark coloration, basal apodeme of aedeagus (usually l...

The existence of polarization sensitivity (PS), most likely resulting from the orthogonal arrangement of microvilli in photoreceptors, has been proposed in cephalopods for some time, although it has rarely been examined behaviourally. Here, we tested the mourning cuttlefish, Sepia plangon, and the reaper cuttlefish, Sepia mestus, for polarization sensitivity using a large-field optomotor stimul...

7 Faculty of Veterinary Science, University of Zimbabwe, P.O. Box MP 167, Mount Pleasant, Harare, Zimbabwe Berne), 8 black-backed and 7 side-striped jackals were vaccinated by oral instillation with doses ranging from 1 0·-1 0• median tissue culture infectious doses (TCID50). Significant serum neutralizing anti body titres were achieved in all the jackals, includ in~ those vaccinated with the l...

In 1987, striped bass (Morone saxatilis) that were nearly dead (moribund) were captured by hand net, and apparently healthy striped bass were caught by hook and line from adjacent waters in the Sacramento-San Joaquin Delta or, alternatively, caught by hook and line from the Pacific Ocean. The livers of these three groups of striped bass were examined for chemical contamination by gas chromatogr...

in sustainable agriculture, using of resistant plants is one of the best methods for integrated pest management. resistance of 140 rice promising lines against striped stem borer was evaluated in two planting date in the field under natural infections in sari agricultural science and natural resources university during 2008-2009. this study carried out as a factorial experiment in randomized co...

Abstract The striped cucumber beetle [StCB; Acalymma vittatum (F.) (Coleoptera: Chrysomelidae)] and the western [WStCB; trivittatum (Mannerheim)] are closely related species of herbivores endemic to North America that specialize on Cucurbitaceae plants. StCB WStCB key pests cucurbit crops can reduce quantity quality yield or even kill plants, especially seedlings, by feeding vectoring pathogens...
