Notes on Two Stone Circles in Shropshire.

Stone circles: form and soil kinematics.

Distinct surface patterns are ubiquitous and diverse in soils of polar and alpine regions, where the ground temperature oscillates about 0 degrees C. They constitute some of the most striking examples of clearly visible, abiotic self-organization in nature. This paper outlines the interplay of frost-related physical processes that produce these patterns spontaneously and presents unique data do...

Notes on Cases of Gall-Stone

In the Johns Hopkin's Hospital Reports for 1890, a paper by Dr Osier appeared " On Fever of Hepatic Origin, particularly the Intermittent Pyrexia associated with Gall-stones," and in this paper Dr Osier states that in the class of case he is describing the characteristic pain of gall-stones may be absent In the Annals of Surgery for August 1895, I drew attention to the fact that absence of pain...

Two Notes on Subshifts

We prove two unrelated results about subshifts. First, we give a condition on the lengths of forbidden words that is sufficient to guarantee that the corresponding subshift is nonempty. The condition implies that, for example, any sequence of binary words of lengths 5, 6, 7, . . . is avoidable. As another application, we derive a result of Durand, Levin and Shen [2, 3] that there are infinite s...

Elastic Behavior of Functionally Graded Two Tangled Circles Chamber

This paper presents the numerical elastic solution for a real problem, functionally graded chamber of hydraulic gear pumps under internal pressure. Because of the similarity and complexity for the considering geometry, a bipolar cylindrical coordinate system is used to extract the governing equations. The material properties are considered to vary along the two tangled circles with a power-law ...
