Research into substituting recycled materials for cement and aggregates can yield beneficial natural resource conservation, waste management, cost savings, reduced embodied energy in concrete. Hence, this research investigates the potential adoption of coal fly ash (CFA) rice husk (RHA) as geopolymer binders to partially substitute varying proportions up 25%. However, cupola furnace slag (CFS) ...

Anopheles gambiae complex mosquitoes comprise different morphologically identical species and the most medically important malaria vectors in Africa. Understanding An. mosquitoes’ mating behaviour is a clue for prevention control of malaria. The factors affecting behavior are age, body size, food finding, type food, host availability environmental temperature. passes through unique strategies. ...

SUMMARY Although sciences and techniques have been significantly developed, many patients are still suffering from diagnostic and therapeutic problems of vestibular system, specially vertigo. Perhaps, these problems are not solved yet mostly because the neurophysiology of vestibular system and the stimulation mechanisms of the receptors are not known. This difficulty, intum, causes some a mbig...

The object of the jeopardy dice game Pig is to be the first player to reach 100 points. Each player's turn consists of repeatedly rolling a die. After each roll, the player is faced with two choices: roll again, or hold (decline to roll again). • If the player rolls a 1, the player scores nothing and it becomes the opponent's turn. • If the player rolls a number other than 1, the number is adde...

The present study provides new data concerning the morphology and distribution of the labial sensilla of 55 species of 12 nepomorphan families (Heteroptera: Nepomorpha) using the scanning electron microscope. On the labial tip, three morphologically distinct types of chemosensilla have been identified: two types of papillae sensilla and one type of peg-in-pit sensilla. Twenty-one morphologicall...

We discuss the results of experiments that illustrate some features of a turbulent mixing zone (TMZ) structure at a gas–liquid interface (Rayleigh–Taylor instability) and at a gas–gas interface accelerated by shock waves (Richtmyer–Meshkov instability). The important feature is the existence of a heavier substance concentration (density) jump at the interface between the heavy medium and the TM...

The effects of brief daily separation, also known as "handling," during the first 2 weeks of life on play behavior and fearfulness toward a predatory odor were assessed in juvenile rats. Handled rats were more playful than nonhandled control rats, and while handling had no effect on the direct response of these rats toward a predatory odor, handled rats did not exhibit a conditioned suppression...
