Category theory, a branch
of mathematics, provides an alternative explanation based on the formal concept of adjunction, which relates a pair of structure-preserving maps, called functors. A functor generalizes the notion of a map between representational states to include a map between state transformations (or processes). In a formal sense, systematicity is a necessary consequence of a higher-order theory of cognitive architecture, in contrast to the first-order theories derived from Classicism or Connectionism. Category theory offers a re-conceptualization for cognitive science, analogous to the one that Copernicus provided for astronomy, where representational states are no longer the center of the cognitive universe-replaced by the relationships between the maps that transform them.”
“Deficiencies of iron, zinc and vitamin A have been a focus
of the governments Selleck Bromosporine and world organizations for decades and extensive efforts check details are being made to address this malnutrition. Being a popular and most common dietary staple of the population living in sub-continent and developing countries, wheat flour (WF) has gained a significant attention as a suitable vehicle for micronutrient fortification. Fortification of wheat flour has been established as an appropriate strategy to curtail micronutrient deficiencies especially in the developing economies. Extent of the prevalence of micronutrient deficiencies, their consequences, selection of a suitable vehicle, choice of fortificants and their levels and storage stability, acceptability and bioavailability of iron and zinc fortified WF are the key points of discussion in the current review. This review further highlights multifaceted issues pertaining to the appropriateness and suitability of fortification over other intervention strategies, ecological needs and fortification success stories
and advantages of simply adding fortificants to flour to meet nutritional requirements of vulnerable groups. The authors have attempted to encompass the subject matter based on their research endeavors made in this direction. (c) 2011 Elsevier Ltd. All rights reserved.”
“Polypropylene (PP)/wasted poly(ethylene terephthalate) (PET) fabric composites and these composites find more modified by maleic anhydride grafted polypropylene (PP-g-MA) and reactive monomers were prepared with a twin-screw extruder. The crystallization morphology, nonisothermal crystallization and melting behavior, crystallization kinetics, and isothermal crystallization kinetics were investigated with differential scanning calorimetry. The results indicated that the wasted fabric (WF) had a heterogeneous nucleation effect on PP in the composites, and this increased the crystallization temperature and induced PP to form transcrystallinity.
