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.

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

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.

Penile self‐injections: an unusual act
International Journal of Dermatology, 2004A 42‐year‐old healthy Thai male presented with a 1‐week history of painful swelling of the penis following self‐injection of two tablets of vitamin A dissolved in 10 mL of tap water with an unsterilized syringe, in order to achieve a more prolonged erection for sexual intercourse, on a friend's advice.

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 ...

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.

The Representation Type of Self-Injective Algebras
Bulletin of the London Mathematical Society, 1990We recall that a finite dimensional algebra \(A\) over an algebraically closed field \(K\) is said to be of wild representation type if there exists a \(K\langle X,Y\rangle\)-\(A\)-bimodule \(N\) which is finitely generated free as left \(K\langle X,Y\rangle\)-module and such that the functor \((-)\otimes_{K\langle X,Y\rangle}N_ A\) from the category ...

Partially Self-Injective Regular Rings
Canadian Mathematical Bulletin, 1973AbstractIt is proved, for any uncountable cardinal λ, that a λ-complete Boolean ring is λ-self-injective. An example shows that the converse need not hold.

Self-Injectable Epinephrine for Allergic Emergencies
The Journal of Emergency Medicine, 2009Anaphylaxis is a severe, life-threatening systemic reaction that can affect all ages. Epinephrine is frequently cited as the first-line and single most important agent in the treatment of severe allergic emergencies. Prompt administration of self-injectable epinephrine by patients and caretakers remains a key component in effective out-of-hospital ...
