Direct Sums of Torsion-Free Covers
, 1973 In [4, Theorem 4.1, p. 45], Enochs characterizes the integral domains with the property that the direct product of any family of torsion-free covers is a torsion-free cover.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Systematics of U-spin sum rules for systems with direct sums
Journal of High Energy PhysicsA rich mathematical structure underlying flavor sum rules has been discovered recently. In this work, we extend these findings to systems with a direct sum of representations. We prove several results for the general case.

On Direct Sums of Injective Modules and Chain Conditions
, 1994 Let R be a ring and M a right R-module. Let σ[M] be the full subcategory of Mod-R subgenerated by M. An M-natural class 𝒦 is a subclass of σ[M] closed under submodules, direct sums, isomorphic copies, and M-injective hulls.

Rings Which Are Sums of Finite Fields
, 1999 We describe all semigroup rings and band-graded rings which are direct sums of finite fields. We show that the class of rings which are direct sums of finite fields is closed for taking sums of two ...

Exploring EADS Modules: Properties, Direct Sums, and Applications in Matrix Rings
Journal of MathematicsWe introduce the concept of an EADS module, defined such that for any decomposition M=A⊕B and any ec-complement C of A in M, the module satisfies M=A⊕C.

Determination of N‑year Design Precipitation in the Czech Republic by Annual Maximum Series Method
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019 The sum of design precipitation of a selected repetition period, provided that it is evenly distributed over the river basin area, is a basic input for the calculation of the direct outflow volume by the curve number method.

Rings Whose Cyclic Modules Are Direct Sums Of Extending Modules
, 2012 Dedekind domains, Artinian serial rings and right uniserial rings share the following property: Every cyclic right module is a direct sum of uniform modules. We first prove the following improvement of the well-known Osofsky-Smith theorem: Acyclic module
