Let R be a ring with 1 and consider the problem of assigning numerical invariants to right K-modules so that two such modules are elementarily equivalent if and only if they have the same invariants. This general problem has been solved by Baur [1], Garavaglia [8], and Monk [18]. The invariants they produce are however rather more model-theoretic than algebraic and are in general highly redunda...

OBJECTIVE To report a technique for semiclosed 1-layer side-to-side jejunocecal anastomosis in horses. STUDY DESIGN Experimental study and clinical reports. SAMPLE POPULATION Part 1--In vitro: Intestinal specimens from 24 horses collected immediately after death at an abattoir. Part 2--CLINICAL CASES: 10 horses with clinical signs of colic requiring jejunocecostomy. METHODS Mean time to p...

The ∼25 N-terminal "HAfp" residues of the HA2 subunit of the influenza virus hemagglutinin protein are critical for fusion between the viral and endosomal membranes at low pH. Earlier studies of HAfp in detergent support (1) N-helix/turn/C-helix structure at pH 5 with open interhelical geometry and N-helix/turn/C-coil structure at pH 7; or (2) N-helix/turn/C-helix at both pHs with closed interh...

Purpose: To investigatge right-to-left shunt determination in dog lungs under inhalantion anesthesia with non-rebreathing and rebreathing systems and fraction of inspired oxygen (FIO2) of 0.9 and 0.4, respectively. Methods: Two groups of 10 dogs each under inhalation anesthesia with sevoflurane: GI in which it was utilized non-rebreathing semiclosed system and FIO2 = 0.9, and GII in which it wa...

BACKGROUND Closed-loop control algorithms in diabetes aim to calculate the optimum insulin delivery to maintain the patient in a normoglycemic state, taking the blood glucose level as the algorithm's main input. The major difficulties facing these algorithms when applied subcutaneously are insulin absorption time and delays in measurement of subcutaneous glucose with respect to the blood concen...

Abstract Let G denote a possibly discrete topological group admitting an open subgroup I which is pro- p . If H denotes the corresponding Hecke algebra over field k of characteristic , then we study adjunction between -modules and -linear smooth -representations in terms various model structures. Gorenstein ring, single out full subcategory equivalent to category all projective via functor -inv...
