We report a simulation study for bottle-brush polymers grafted on a rigid backbone. Using a standard coarse-grained bead-spring model extensive molecular dynamics simulations for such macromolecules under good solvent conditions are performed. We consider a broad range of parameters and present numerical results for the monomer density profile, density of the untethered ends of the grafted flex...

OBJECTIVE To determine the frequency and compare the culture yield of bacterial isolation by conventional and blood culture BACTEC bottle techniques in cirrhotic patients with spontaneous bacterial peritonitis (SBP). STUDY DESIGN Cross-sectional comparative study. PLACE AND DURATION OF STUDY Pathology Department, Bannu Medical College, Bannu, KPK, from January 2012 to December 2013. METHO...

Extensive Monte Carlo results are presented for the structure of a bottle-brush polymer under good solvent or theta solvent conditions. Varying the side chain length, backbone length, and the grafting density for a rigid straight backbone, both radial density profiles of monomers and side chain ends are obtained as well as structure factors describing the scattering from a single side chain and...

INTRODUCTION The World Health Organization recommends breastfeeding for two years or more and advises against bottle feeding and pacifier use. OBJECTIVE Investigate the association between bottle feeding and pacifier use, and breastfeeding in the second half-year of life. METHODS Survey in a municipality of Rio de Janeiro state, in 2006, interviewing those responsible for 580 children aged ...

Results 506 of the 802 guardians/children referred to the PPM joined. As for the children, the most frequently assessed habits were: bottle (56.1%), bottle and pacifier (18.4%), finger (11.9%), bottle and finger (7.1%), pacifier (5.7%), pacifier and finger (0.6%), and bottle/pacifier/finger (0.2%). After parent participation in the meetings, 335 (66.2%) children abandoned their habits. There wa...

Baby bottle tooth decay is a unique pattern of dental caries (tooth decay) affecting the dentition of young children. It is associated with the practice of putting the child to sleep with a nursing bottle filled with liquid that contains sugar. Practitioners who treat Native American children have noted that this population suffers from a high prevalence of the condition. In order to establish ...
