Tribolium castaneum and Tribolium confusum can be monitored in food processing facilities using traps baited with pheromones and kairomones, but beetle response to traps might be enhanced by adding visual cues. Against a white background, T. castaneum adults were more likely to visit black pillars than white pillars when presented with a choice (e.g., 73% of beetles visited black and 17% visiti...

| We consider the following problem: Let r be a n-bead rosary with m white beads and n ? m black beads. Let t be an integer, t n. Denote by MC t (r) the number of pairs, of monochromatic beads which are within distance t apart, in the rosary r. What is the minimum value of MC t (), when the minimum is taken over all n-bead rosaries which consists of m white beads and n ? m black beads? We prove...

We present a static solution for d = 2 critical string theory including the tachyon T but not its potential V (T ). This solution thus incorporates tachyon back reaction and, when T = 0, reduces to the black hole solution. When T 6= 0 one finds that (1) the Schwarzschild horizon of the above black hole splits into two, resembling Reissner-Nordstrom horizons and (2) the curvature scalar develops...

Novel static, time-dependent and spatial-temporal solutions of Einstein field equations, displaying singularities, with and without horizons, and in several dimensions are found based on a dimensional reduction procedure widely used in Kaluza-Klein type theories. The Kerr-Newman black-hole entropy as well as the Reissner-Nordstrom, Kerr and Schwarzschild black-hole entropy are derived from the ...

The application of urea-based selective catalytic reduction products (i.e., Urea-SCR) provides a NOx and, therefore, minimizes pollution emissions from vehicles fueled by diesel. Such can be easily found in the market; however, they are often susceptible to adulteration, mainly terms urea content and dilution with non-mineralized water. In this study, we propose simple, low-cost, disposable, st...

In this paper, we study the accretion process for fluids flowing near a black hole in the context of f (T ) teleparallel gravity. Specifically, by performing a dynamical analysis by a Hamiltonian system, we are able to find the sonic points. After that, we consider different isothermal test fluids in order to study the accretion process when they are falling onto the black hole. We find that th...

Deer are considered important intermediate hosts for the coccidian parasites, Toxoplasma gondii and Neospora caninum. Antibodies to N. caninum and T. gondii were determined in sera of 42 mule deer (Odocoileus hemionus hemionus) and 43 black-tailed deer (Odocoileus hemionus columbianus) from Washington state, USA, using direct agglutination test with specific antigens. A titer of 1:25 was consid...
