Let (X,Γ) be a uniform space with its uniformity generated by a set of pseudo-metrics Γ. Let the symbol “ ' ” denote the usual infinitesimal relation on ∗X, and define a new infinitesimal relation “ ≈ ” on ∗X by writing x ≈ y whenever ∗ρ(x, p) ' ∗ρ(y, p) for each ρ ∈ Γ and each p ∈ X. We call (X,Γ) an S-space if the relations ' and ≈ coincide on fin(∗X). S-spaces are interesting because their n...

Soybean hulls have been successfully fed to ruminant animals as an economical substitute for hay. This feedstuff is a source of highly digestible fiber that does not contain starch. The purpose of this trial was to evaluate soybean hulls as a replacement fiber in horse diets. Four cecally cannulated Quarter Horse geldings, aged 6 to 10 yr and averaging 502 kg, were used in a 4 x 4 Latin square ...

Effects of percentage of roughage on growth, serum urea N, NEFA, and IGF-1 concentrations and wool, carcass, and fatty acid (FA) characteristics were investigated in Rambouillet wether lambs (n = 33). Lambs were individually fed ad libitum pelleted diets for 98 d containing 40% dried distillers grains and other ingredients, with 10% (CSH10), 20% (CSH20), or 30% (CSH30) cottonseed hulls replacin...

In this paper, we provide an abstract characterization of the inverse hulls semigroups associated with Markov shifts. As application give example shifts that are not conjugate, but have isomorphic hulls.

We discuss a new type of weak factorization system. Although these systems provide (up to isomorphism) uniquely determined decompositions of morphisms, in general they do not constitute orthogonal factorizations and are not even functorial. Nevertheless, they arise naturally, as injective hulls or projective covers in comma categories. Surprisingly, often injective hulls and projective covers c...

Fouling of ships is an important historical and enduring transfer mechanism of marine nonindigenous species (NIS). Although containerships have risen to the forefront of global maritime shipping since the 1950s, few studies have directly sampled fouling communities on their submerged surfaces, and little is known about differences in the fouling characteristics among commercial ship types. Twen...

An experiment was conducted to evaluate the effects of feeding co-products with Optigen ® II on animal performance and blood metabolites in growing beef calves. Angus steers were allowed ad libitum access to bahiagrass hay and were supplemented for 42 d via Calan gates. Treatments included 1) dried distillers grains; 2) dried distillers grains + Optigen; 3) soybean hulls; 4) soybean hulls + Opt...

Known properties of ‘‘canonical connections’’ from database theory and of ‘‘closed sets’’ from statistics implicitly define a hypergraph convexity, here called canonical convexity (cconvexity), and provide an efficient algorithm to compute c-convex hulls. We characterize the class of hypergraphs in which c-convexity enjoys the Minkowski–Krein–Milman property. Moreover, we compare c-convexity wi...

Effects of the use of 200 g of either wheat bran, sugar beet pulp, soya bean hulls or alfalfa meal per kilogram diet on the digestive process of the weaned piglet were studied on 24 Duroc Landrace male piglets, weaned at 28 days of age. Piglets had an initial mean live weight of 7.92( 1.1) kg and were randomly distributed in six successive blocks of four animals. The total tract apparent digest...
