Commutative Self-Injective Rings
Canadian Journal of Mathematics, 1970All rings considered here are commutative containing at least two elements, but may not have identity. A ring R is said to be selfinjective if R as an R-module is injective. A ring R is said to be pre-selfinjective if every proper homomorphic image of R is ...

There are very few general results known for the maximal ring of quotients for rings with non-zero singular ideal. Most of the results deal with the case when the maximal ring of quotients is a self-injective ring, a case which will be studied in this Chapter.

A Note on a Self Injective Ring
Canadian Mathematical Bulletin, 1971The purpose of this note is to give a direct proof of Koh's main theorem in [2, p. 31] applying well-known theorems of Faith and Utumi. While doing so, we shall mention a general theorem from which Koh's theorem may be obtained as a corollary.

Multiple Sclerosis Journal, 2005
Anxiety and phobia frequently prevent patients with multiple sclerosis (MS) from self-injecting their injectable disease-modifying medications. This small, randomized, controlled trial tested the efficacy of a six-session nurse-administered programme to teach self-injection to patients with MS, who, due to anxiety or phobia, were unable to self-inject

Sums of units in self-injective rings
Journal of Algebra and Its Applications, 2014We prove that if no field of order less than n + 2 is a homomorphic image of a right self-injective ring R, then for any element a ∈ R and central units u1, u2, …, un ∈ U(R) there exists a unit u ∈ U(R) such that a + uiu ∈ U(R) for each i ≥ 1.

Self-Injection of a Dipteran Parasitoid into a Spider
Naturwissenschaften, 1999A host invasion strategy hitherto unknown from other insect parasitoids was observed in the dipteran Acrocera orbicula (Fabricius) (Diptera: Acroceridae) parasitizing the wolf spider, Pardosa prativaga (L. Koch) (Araneida: Lycosidae). In laboratory experiments the free-living first instar acrocerid larvae attached themselves firmly to the spiders ...

A NOTE ON PERFECT SELF-INJECTIVE RINGS
The Quarterly Journal of Mathematics, 1994A ring \(R\) is called quasi-Frobenius if \(R\) is right (or left) Artinian and right (or left) self-injective. Define inductively the \(k\)th right socle \(S_ k\) of \(R\) as follows: \[ S_ 1=\text{Soc}(R_ R),\;S_ 2/S_ 1=\text{Soc}(R_ R/S_ 1),\;\dots,\;S_{k + 1}/S_ k=\text{Soc}(R_ R/S_ k)\;\dots \] It is well-known that a right perfect, right and left

Phencyclidine-analogue self-injection by the baboon
Psychopharmacology, 1984Self-injection of phencyclidine HCI (PCP) and four of its analogues was examined in baboons. IV injections of drug were dependent upon completion of 160 lever presses (a 160-response fixed-ratio schedule). A 3-h time-out period followed each injection, permitting a maximum of eight injections per day.

Schedule-induced self-injection of drugs
Neuroscience & Biobehavioral Reviews, 1982Studies of acquisition and maintenance patterns of drug intake, including dependence, necessitate voluntary intake of drugs. Voluntary intake in animal studies is difficult to achieve because of aversive taste factors associated with most drugs, and involuntary or forced choice methods obscure the behavior which is the object of study.
