Instructional materials development for primary Spanish in the Caribbean
(School of Education, UWI, St. Augustine, 2008)
In recent years, several Caribbean countries have stated their commitment to implement Spanish as a foreign language in the primary school curriculum. This initiative exposed certain needs: syllabus, teacher training, and ...
Influence of heat treatment on LiNbO3 thin films prepared on Si(111) by the polymeric precursor method
(1999-07-01)
The effects of heat-treatment temperature on LiNbO3 thin films prepared by the polymeric precursor method were investigated. The precursor solution was deposited on Si(111) substrates by dip coating. X-ray diffraction and ...
Optimization of substrate preparation for oyster mushroom (Pleurotus ostreatus) cultivation by studying different raw materials and substrate preparation conditions (composting: phases I and II)
(Springer, 2016-11-01)
In recent years, oyster mushroom ( Pleurotus ostreatus) has become one of the most cultivated mushrooms in the world, mainly in Brazil. Among many factors involved in a mushroom production, substrate preparation is the ...
A priori reformulations for joint rolling-horizon scheduling of materials processing and lot-sizing problem
(2013-06-10)
In many production processes, a key material is prepared and then transformed into different final products. The lot sizing decisions concern not only the production of final products, but also that of material preparation ...
Finite element analysis of the influence of geometry and design of zirconia crowns on stress distribution
(Wiley-Blackwell, 2015-02-01)
Purpose: To evaluate the influence of the geometry and design of prosthetic crown preparations on stress distribution in compression tests, using finite element analysis (FEA). Materials and Methods: Six combinations of ...
