Although this study was originally designed to compare the efficacy of two different stable fly traps within 10 sites at a 12-ha zoological park, seasonal and spatial population distribution data were simultaneously collected. The two traps included an Alsynite fiberglass cylindrical trap (AFT) and a blue-black cloth target modified into a cylindrical trap (BCT). Both traps were covered with st...

This experiment was designed to determine whether Transcendental Meditation has an effect upon the auditory frequency and amplitude discrimination thresholds. These thresholds were measured for each subject, using the ' warble ' technique, before and after twenty minutes meditation, and before and after reading a bookfor twenty minutes (the control). A significantly greater improvement was foun...

plants firing fuel oil produce huge quantities of fly ash as solid waste, which needs to becharacterized prior to its proper management. it is worth mentioning that the published literature lackcomprehensive information on the characteristics of such fly ash. characteristics of fuel oil fly ash producedat selected power (pp) and water desalination (dp) plants were determined. the results showed...

This paper reports the results of a series of investigations of comfortable loudness levels with particular reference to their application to hearing aid gain prescriptions. Experiment 1 studied the effects of several stimulus waveforms, bandwidths, and durations on comfortable loudness levels for normal and hearing impaired listeners. Speech band comfort levels were found to be significantly h...

Abstract Background: Photocatalytic process is used as a suitable method for o-chlorophenol removal. In this study, the efficiency of a mixture of modified fly ash and TiO2 nanoparticles in photocatalytic removal of o-chlorophenol was evaluated. Methods: After acid washing of fly ash, the absorbent was oxidized with potassium permanganate. ...

The prevalence of trypanosome infections in tsetse flies, Glossina pallidipes, collected from Chiawa and Chakwenga in Zambia with endemic trypanosomosis was assessed by polymerase chain reaction (PCR). Out of the 550 G. pallidipes, 58 (10.5%) flies were found to harbor trypanosome DNA. Infection rates of tsetse with Trypanosoma vivax universal, Trypanosoma congolense savannah, T. congolense for...

the identification of different species of simuliidae, also called “black fly”, is based on particular structure of oral and terminal appendages of their larvae add also on the special morphology of adults and pupaes. because of their considerable flight range, the problem of finding their resting places, and also the difficulties of collecting the adult flies, breeding of this insect, in the l...

background: laboratory bred sand flies are essential for the study of different biological phenomena including the transmis­sion dynamics of leishmania . the aim of the study was to determine the suitable situation for colonization and main­tenance of iranian strain of phlebotomus papatasi at laboratory conditions from an endemic focus of cutaneous leishmani­asis due to leishmania major . metho...
