BACKGROUND AND STUDY AIMS Compared with air insufflation, water exchange and carbon dioxide (CO2) insufflation have been shown to reduce colonoscopy discomfort; however, head-to-head studies of the two methods are lacking. We aimed to compare water exchange and CO2 insufflation directly with regard to pain during primary unsedated colonoscopy. METHODS Patients willing to undergo unsedated col...
An investigative study was carried out to determine the bacteriological and physicochemical qualities of borehole and well water samples in Ijebu-Ode, Southwestern Nigeria. Ten water samples each of borehole and well water sources were collected within the geographical location. Physicochemical parameters were determined using standard methods. The total bacterial count was determined by pour p...
The notion of zero-knowledge [GMR85] is formalized by requiring that for every malicious efficient verifier V ∗, there exists an efficient simulator S that can reconstruct the view of V ∗ in a true interaction with the prover, in a way that is indistinguishable to every polynomialtime distinguisher. Weak zero-knowledge weakens this notions by switching the order of the quantifiers and only requ...
Insects are at high risk of desiccation because of their small size, high surface-area-to-volume ratio, and air-filled tracheal system that ramifies throughout their bodies to transport O(2) and CO(2) to and from respiring cells. Although the tracheal system offers a high-conductance pathway for the movement of respiratory gases, it has the unintended consequence of allowing respiratory transpi...
emph{ Smooth Projective Hash Functions } ( SPHFs ) as a specific pattern of zero knowledge proof system are fundamental tools to build many efficient cryptographic schemes and protocols. As an application of SPHFs, emph { Password - Based Authenticated Key Exchange } ( PAKE ) protocol is well-studied area in the last few years. In 2009, Katz and Vaikuntanathan described the first lattice-based ...
