The time is ripe to start a science of identities for their own sake, without paying lip-service to high-brow mathematics. Although putting combinatorial, (abstract-) algebraic or analytic flesh and blood on identities did lead and will lead to considerable insight as well as new identities, there is also much to be gained in forgetting advanced mathematics, and starting a new sub-discipline of...

introduction: there are two types of japanese persimmon (diospyros kaki thunb.), astringent and non-astringent, based on the degree of astringent taste at maturity state. fruits of either type are strongly astringent when small and immature, but non-astringent type loses its astringency during development on the tree, still with firm flesh. however, the astringent type keeps its astringency and...

Winter pruning has been a common practice in peach. Twig topping associated with it, but this used at the same intensity, regardless of cultivar. Therefore, study aimed evaluating productive behavior and quality ‘Maciel’ peach grafted on ‘Capdeboscq’ ‘Okinawa’ (P. persica) as rootstocks, when they were submitted to different twig intensities winter pruning. The following three evaluated: short ...

Light scattering is related to the structural characteristics of fruit and hence is potentially useful for estimating fruit firmness. This research investigated hyperspectral scattering as a means for measuring peach fruit firmness. A hyperspectral imaging system was used to simultaneously acquire 153 spectral scattering profiles, generated by a broadband light beam, from ‘Red Haven’ and ‘Coral...

Topical microbicides are a promising solution to address the global threat of HIV and other sexually transmitted infections. To be successful, a microbicide not only needs to be biologically functional but also highly acceptable to users. User acceptability of microbicides can be incorporated early in the product formulation and design process. Previous qualitative research revealed women had s...
