Given a remarkable representation of the generalized Pauli operators of two-qubits in terms of the points of the generalized quadrangle of order two, W (2), it is shown that specific subsets of these operators can also be associated with the points and lines of the four-dimensional projective space over the Galois field with two elements — the so-called Veldkamp space of W (2). An intriguing no...

background : plasmodium falciparum infection is endemic in most tropical countries and will definitely infect human immunodeficiency virus (hiv) positive patients living in this region at one time or the other during the course of their infection. this study was conducted to determine the prevalence of malaria infection in hiv-infected patients on highly active antiretroviral therapy in benin c...

Abstract Background The aim of the study is to assess bonding two repair methods for zirconia. Null hypothesis Repair zirconia with Cojet (3M sand, 68,411) and clearfil (clearfil REPAIR Kuraray Japan) has same effect on bond strength restorations. Zirconia blocks were sliced before sintering into 28 samples (inCorisZI mono L), surface treated (Cojet clearfil) then bonded composite. Storage ther...

BACKGROUND Prolonged sitting is prevalent in the workplace and is associated with adverse health markers. PURPOSE Investigate the effects of point-of-choice (PoC) prompting software, on the computer used at work (PC), to reduce long uninterrupted sedentary periods and total sedentary time at work. DESIGN Assessor-blinded, parallel group, active-controlled randomized trial. SETTING/PARTICI...

background: there has been increasing awareness throughout the world regarding the remarkable decrease in amphibian population. for such amphibian population decline several causes have been given. cadmium, a heavy metal is released both from natural sources (leaching of cadmium rich soils) and anthropogenic activities to the aquatic and terrestrial environments. this study evaluated the toxici...
