Context. The Hertzsprung-Russell diagram is a key diagnostic diagram for stellar structure and evolution, which is now in use for more than 100 years. Aims. We introduce a new diagram which is based on the gravity-effective temperature diagram, but has various advantages. Methods. Our spectroscopic Hertzsprung-Russell (sHR) diagram shows the inverse of the flux-mean gravity versus the effective...

Appendix B of The Principles of Mathematics (1903) contains Russell’s first statement of his theory of logical types. This simple version of the theory is designed to block the reasoning that leads to the paradox of the Russell class. But Russell notes immediately that new problems arise. The problems culminate in the paradox of propositions. This is a problem that seems to run in exact paralle...

In this paper I measure the progressive potentiality of art against Russell Kirk’s notion “normative art”. Kirk argues that good literature cultivates virtue according to a transcendent norm, law nature. interrogate extent which can be conservative own meaning conservatism and read his itself in an effort show its tenets detrimentally supersede contradict others. The criticism discussion normat...

A novel pure rotary actuator with a double-layer flexible mechanism (RA-DFM), which is driven by single piezoelectric ceramic in the lower and generates rotational motion upper mechanism, proposed this paper. The output of successively amplified using an enhanced double Scott–Russell two lever-type mechanisms to obtain large rotation range. static, kinematic dynamic properties RA-DFM are numeri...

Russell body gastritis is a rare form of chronic gastritis. It is characterized by the invasion of lamina propria by plasma cells that included eosinophilic cytoplasmic inclusion. In the literature, most of the cases are associated with Helicobacter pylori. Russell body gastritis and Helicobacter pylori infection are generally seen together incidentally. We report here two cases of Russell body...

Frank Russell, 2nd Earl Russell (1865–1931), was a man of rational thought and social conscience who, released from his early imbroglios, embarked on controversial career, throwing name political weight behind range desperate but often successful causes. This bibliographical guide acknowledges labours, illustrates diversity demonstrates why deserves to be taken seriously.

Russell and Walker proposed different ways of constructing instants from events. As an explanation of “time as a continuum”, Thomason favoured Walker’s construction. The present paper shows that Russell’s construction fares as well. To this end, a mathematical characterization problem is solved which corresponds to the characterization problem that Thomason solved with regard to Walker’s constr...
