in this paper we define the removable cycle that, if $im$ is a class of graphs, $gin im$, the cycle $c$ in $g$ is called removable if $g-e(c)in im$. the removable cycles in eulerian graphs have been studied. we characterize eulerian graphs which contain two edge-disjoint removable cycles, and the necessary and sufficient conditions for eulerian graph to have removable cycles h...

Tourniquet-induced peripheral neuropathy is at least partially attributable to excessive forces applied to the nerves beneath cuffs inflated to high pressures. Lowering the inflation pressure to the minimum necessary to obtain an effective arrest of blood flow distal to the tourniquet cuff should increase the safety of these systems. Tourniquet cuffs with widths varying from 4.5 cm to 80 cm wer...

The Report of the President’s Commission on Financial Structure and Regula&n [19] (hereafter the Hunt Report) recommends important changes in the regulation, supervision, and operation of all major financial intermediaries. A common thread throughout the Hunt Report is the view that financial institutions should operate under the minimum necessary regulation. In this regard the Hunt Report prop...

And what if the only reality in existence was virtual reality? The individual identity in virtual reality has always been studied with regards to individual identity in reality. Indeed, the individual in virtual reality is considered as a real individual to whom we removed fundamental features: spatial unity (Leibniz) and temporal identity or sameness (Ricoeur, 1990). In other words, a virtual ...

We say an algebraic object or property over a field k is arithmetic if it becomes trivial or vanishes after finite separable base extension. Since such objects or properties owe their existence to the presence of “arithmetic gaps” in k, i.e., the failure of k to be algebraically closed, we view them as responses to specific arithmetic properties of k, and we study them in order to gain insight ...

1. A function is arithmetic if it is defined on the positive integers. Those arithmetic functions which assume real values and satisfy f(ab)-f(a)+f(b) for mutually prime integers a, b are classically called additive. The following examples illustrate the interest of these functions, both for themselves and for their applications. An additive function is defined by its values on the prime powers...
