The use of the ice slurry is recently applied in the refrigeration and air conditioning systems. Advantages such as the possibility to store latent heat on ice and the possibility of being pumped as cold water can be considered. Ice slurries can be used both for cold storage in place of chilled water or ice and as a secondary refrigerant since, up to certain concentrations, they can be pumped directly through distribution pipeworks and heat exchangers.

We begin by studying orbifolds, i.e., topological spaces locally homeomorphic to quotients of Rn by finite groups. Then we study Seifert fiber spaces of dimension three which are certain type of foliations by circles that can be seen as fiber bundles over orbifolds. This material is useful in the subsequent study of Thurston model geometries. A Thurston model geometry is a pair (G;X), where X is a connected and simply connected manifold and G is a group of diffeomorfisms of X with certain proper...

Two forms of complexity in Euclidean plane geometry are considered. In the first one, problems are described algebraically, and the complexity level is measuredessentially by the degree of a polynomial. As a consequence, many familiar and general results in geometry can be proved by inspecting two or three special cases. The second form uses the syntactic description of a theorem allowing for a quanti.cation of the complexity in logic terms (number of quantifiers and atoms in the formula). Inspi...

The standard CAPM (Capital Asset Pricing Model), proposed by Sharpe, Lintner and Mossin, is one of the most important paradigms of finance theory. It states that the expected mean return on an asset is a linear function of its non-diversifiable risk or systematic risk. The expected market risk premium is the slope of this function, and the risk-free return is the intercept. One of its main assumptions is that investors can lend and borrow at the risk-free rate.The Zero-Beta CAPM, proposed by Bla...

Along the past forty years, an increasing interest on composite materials formed by theaddition of discrete fibers to a concrete matrix is being observed. These composites are knownas fiber reinforced concretes. The interest on the use of fibers as reinforcement is justified bytheir significative contribution to concrete thoughness, as they reduce the brittle characteristicsof that material. In fact, due to fiber reinforcement mechanism, fiber reinforced concrete canabsorb much more strain energ...
