Abstract Background Pneumococcal nasopharyngeal colonization (copyright) generally precedes pneumococcal disease.The purpose of this study was to determine the prevalence of copyright and to identify the pneumococcal serotypes circulating among Bhutanese children under five years of age admitted with clinical pneumonia, before the introduction of p
Group B streptococcus (GBS) is the major pathogen causing diseases in neonates, pregnant/puerperal women, cows and fish.Recent studies have shown that GBS may be infectious across hosts and some fish GBS strain might originate from human.The purpose of this study is to investigate the genetic relationship of CC103 strains that recently emerged in c
This paper proposes the binary comprehensive learning particle swarm optimization (BCLPSO) method to determine the optimal design for nonlinear steel structures, adopting standard member sizes.The design complies with the AISC-LRFD standard specifications.Moreover, the sizes and layouts of cross-brace members, appended to the steel frames, are simu
Background and Objectives: Sulphate ion is one of the main ions available in natural and waste water.The high rate of sulphate in drinking water causes health canon imageclass mf227dw problems such as irritation and digestive problems and makes water taste bitter.The purpose of this study was to assess the efficiency of sulphate ion removal from dr
TiO2 nanoparticles were immobilized on two porous materials used as catalyst supports, namely, activated carbon (AC) and natural clay (NC), through an impregnation process using TiO2 (P25) as precursor.The so-prepared composite materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transition electron microscop
