The world of social media influencers, bloggers and online “clothes horses” is a relatively new one. New-media personalities, a.k.a. “clothes horses”, are now endorsing brands, products and companies in a more subtle way than through traditional advertising. They carefully cultivate and position their personal brands with a view to persuading businesses to use them for relatively inexpensive, o...

Conformations of a bottle-brush polymer with two types (A,B) of grafted side chains are studied bymolecular dynamics simulations, using a coarse-grained bead-springmodel with side chains of up to N = 50 effective monomers. Varying the solvent quality and the grafting density, the crossover from the “pearl-necklace” structure to dense cylinders is studied. Whereas for small grafting density, Aan...

Here presented are the definitions of (c)-Riordan arrays and (c)-Bell polynomials which are extensions of the classical Riordan arrays and Bell polynomials. The characterization of (c)-Riordan arrays by means of the Aand Z-sequences is given, which corresponds to a horizontal construction of a (c)Riordan array rather than its definition approach through column generating functions. There exists...

Personality has become an increasingly important area in sport psychology as attempts are made to understand, explain, and predict levels of sporting involvement and success. To further understand these relationships, 312 Grade 11 and 12 students completed a battery of personality and mood-state inventories consisting of the STAI, EPQ and POMS, and were then categorized by (i) participation in ...

The ferrihydrite-goethite transformation in samples of pureand Mn-ferrihydrite was investigated in order to elucidate the effect of Mn(II) in the aging process. Samples of pureand Mn-ferrihydrites were aged for different times, and their structural changes were described on the basis of Rietveld structure refinements. A comparison of two series of samples with (A-series) and without Mn (F-serie...

Aand B-modes ultrasonographic changes in the thickness of various structures of the eyeball in male and female English Cocker Spaniel dogs with and without nondiabetic cataracts were evaluated. Sixteen dogs with cataracts (32 eyes) and seven normal dogs (14 eyes) older than eight years were selected. Aand B-modes ultrasonography was performed with a 10MHz transducer. Data was statistically eval...

Eight vegetables were pre-treated with and without sa­ ponification, and chromatographed by reversed-phase HPLC. Carote11Oid peaks were identified using seven reference standards. Samples extracts were also chromatographed llsing a mixed magnesia and diatomaceous earth column. Fractions were eluted using stepwise increases in the proportion of acetone in hexane, studied by UV-VIS ab­ sorption s...
