Objective: to compare the state of coagulation system in patients with ischemic stroke and coronavirus disease those without disease. Materials methods. We examined 40 acute period cerebral stroke, aged from 69 87 years (average age 77.30 ± 2.08 years). They were divided into two groups: group I — SARS-CoV-2-positive, II SARS-CoV-2-negative. Group consisted 20 individuals (9 women 11 men) 84 76...

although it is not often thought of, elderly abuse is a frequently occurring phenomenon. especially when an older patient dies, maltreatment is low on the list of possible causes of death. there are, however, signs that may point in the direction of abuse. these can either be on the patient’s body, in the surroundings, or within the story as to how the patient died. attention should be paid to ...

The standard semantic definition of consequence with respect to a selected set X of symbols, in terms of truth preservation under replacement (Bolzano) or reinterpretation (Tarski) of symbols outside X, yields a function mapping X to a consequence relation ⇒X . We investigate a function going in the other direction, thus extracting the constants of a given consequence relation, and we show that...

The first consistent analysis of asymptotic approximation of geometrical optics (GO) of electromagnetic waves in smoothly inhomogeneous isotropic media was made in a work by Rytov [1]. There he studied the GO in first approximation; also he gave a well-known law of rotation of polarization plane for electromagnetic wave. Geometrical attributes of this law were described further in detail by Vla...

It is well established that in the pathology of the cardio-vascular system (CVS) only a portion of the blood volume (BV) can be in active circulation. This portion of BV is named the actively circulating volume (ACV) and is evaluated from a monotone decrease of dilution curve produced by an intravascular tracer. In given paper is presented Markov chain as a math model of the flow of a tracer th...

Bursty dynamics of agents is shown to appear at criticality or in extended Griffiths phases, even in case of Poisson processes. I provide numerical evidence for a power-law type of intercommunication time distributions by simulating the contact process and the susceptible-infected-susceptible model. This observation suggests that in the case of nonstationary bursty systems, the observed non-Poi...
