Evolution of an elemental theory of Pavlovian conditioning [PDF]

open access: yesLearning & Behavior, 2008
Kenneth Spence (1936, 1937) formalized a quantitative, elemental approach to association theory that has had a broad and dominating influence on learning theory for many years. A set of challenges to the basic approach has spurred the subsequent evolution of elemental theory in various ways.

TRACE ELEMENTS IN THE TREATMENT OF RHEUMATIC CONDITIONS

open access: yesRheumatic Disease Clinics of North America, 1999
The role of trace metallic elements (copper, selenium, zinc, gold) in chronic inflammatory states is of great interest because many of them are co-factors in metabolic processes involving articular tissues and immune system function. Deficiencies of several of these have been documented in patients with rheumatoid arthritis.

Technical and economic evaluation of justification for preventing negative effects of feedback in local elements of interaction of rail yards [PDF]

open access: yesSHS Web of Conferences, 2019
The operation of rail yards is characterized not only by direct links, but also by feedback in the local elements of interaction, resulting in a violation of interaction conditions between adjacent elements, which causes a negative effect on the state ...

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
