Nutrient intake and urine composition were analyzed in calcium oxalate (CaOx)stone-forming and healthy control dogs to identify factors that contribute to CaOx urolithiasis. Stone-forming dogs had significantly lower intake of sodium, calcium, potassium, and phosphorus and significantly higher urinary calcium and oxalate concentrations, calcium excretion, and CaOx relative supersaturation (RSS)...

The production of concretes with a hard hardening rate is not feasible without the use modifying additives. development chemical industry has led to emergence large number additives different properties. Some increase frost and corrosion resistance, strength building materials, while others affect setting concrete water-cement ratio. Of greatest interest joint work in composition cement stone. ...

Gallbladder bile from patients with cholesterol stones and control patients without cholesterol stones was analysed for the relative concentrations of bile salts, phospholipids, and cholesterol. It was not possible to distinguish stone-forming from control biles when these were plotted on triangular coordinates. There was a significant increase in the dihydroxy: trihydroxy bile salt ratio in th...

The concepts of finite join and finite meet in a lattice are introduced. Some properties of the finite join are proved. After introducing the concept of dual lattice in view of dualism we obtain analogous properties of the meet. We prove these properties of binary operations in a lattice, which are usually included in axioms of the lattice theory. We also introduce the concept of Heyting lattic...

Mini-slab electrophoresis on sodium dodecyl sulfate/polyacrylamide gel can be used to detect protein in unconcentrated urines containing more than 100 mg of protein per liter. Several urinary proteins--including albumin, transferrin, and the Tamm-Horsfall mucoprotein--precipitate, partly or totally, if urine samples are stored at 4 degrees C for one or two days. The present procedure permits id...

Brouwerian ordered sets generalize Brouwerian lattices. The aim of this paper is to characterize α-complete Brouwerian ordered sets in a manner similar to that used previously for pseudocomplemented, Stone, Boolean and distributive ordered sets. The sublattice G(P ) in the Dedekind-Mac Neille completion DM(P ) of an ordered set P generated by P is said to be the characteristic lattice of P . We...

We present a duality theorem for bounded lattices that improves and strengthens Urquhart's topological representation for lattices. Rather than using maximal, disjoint lter-ideal pairs, as Urquhart does, we use all disjoint lter-ideal pairs. This allows not only for establishing a bijective correspondance between lattices and a certain kind of doubly ordered Stone Spaces (Urquhart), but for a f...

Several biliary proteins have cholesterol crystallisation promoting activity. One of these glycoproteins is aminopeptidase-N, a canalicular ectoenzyme. This study attempted to localise aminopeptidase-N along the biliary tree, to assess its concentration in a series of 98 patients subjected to abdominal surgery, 40 of them without gall stones, and to correlate its concentration with cholesterol ...

We study the evolution of altruism in one- and two-dimensional stepping-stone populations with discrete overlapping generations. We find that increasing survival probability facilitates the evolution of altruism, in agreement with recent results for a patch-structured population. We allow the altruistic behaviour to affect either fecundity or survival probability. In the first case, altruism is...

In this note we introduce and study algebras ( L , V, A, 1, 0,l) of type (2,2,1,1,1) such that ( L , V, A, 0 , l ) is a bounded distributive lattice and -,is an operator that satisfies the conditions -,(a V b ) = -,a A -,b and -0 = 1. We develop the topological duality between these algebras and Priestley spaces with a relation. In addition, we characterize the congruences and the subalgebras o...
