Knowledge of factors that influence oviposition behavior of malaria mosquitoes is critical to vector control measures aimed at larval habitat modifications and source reduction. Anopheles minimus s.l., an important malaria vector in Southeast Asia, generally breeds in clear, unpolluted water along shaded grassy edges of slow-moving streams. The objective of this study was to determine the influ...

BACKGROUND Previous studies have reported that the design of the water dispensers can influence the water intake in farm animals. Horses and dairy cows seem to prefer to drink from an open surface whereas sheep and pigs apparently prefer water nipples, probably because of the worse water quality in water bowls. The aim of the present study was to examine the preference of dairy goats for water ...

Complexes formed by anions and substituted molecular bowls were studied by means of computational methods. The bowls consisted of corannulene molecules substituted with five or ten F, Cl, or CN groups, whereas Cl(-), Br(-) and BF(4)(-) were the anions considered. Substitution with F, Cl and CN hardly affects the geometry of the bowl, but produces an inversion of the molecular electrostatic pote...

We study the phase behavior of bowl-shaped particles using computer simulations. These particles were found experimentally to form a metastable wormlike fluid phase in which the bowl-shaped particles have a strong tendency to stack on top of each other [M. Marechal, Nano Lett. 10, 1907 (2010)]. In this work, we show that the transition from the low-density fluid to the wormlike phase has an int...

BACKGROUND Cell salvage is an essential element in the concept of blood management. Modern devices provide different bowl sizes and sensor-directed programs to optimally adjust to varying clinical situations. STUDY DESIGN AND METHODS In an experimental performance study, the discontinuous autotransfusion device XTRA (LivaNova/Sorin) was evaluated using fresh donor blood anticoagulated with he...

Concern over the status of bees has increased the need to inventory bee communities and, consequently, has increased the need to understand effectiveness of different bee sampling methods. We sampled bees using bowl traps and netting at 25 northwest Indiana sites ranging from opengrasslands to forests.Assemblagesofbees captured inbowl traps andbynettingwerevery similar, but this similarity was ...

We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl’s natural vibrational modes ...
