Tattooing is a permanent form of body art applied onto the skin with a decorative ink, and it has been practiced from antiquity until today. The number of tattooed people is steadily increasing as tattoos have become popular all over the world, especially in Western countries. Tattoos display distinctive designs and images, from protective totems and tribal symbols to the names of loved or lost persons or strange figures, which are used as a means of self-expression. They are worn on the skin as a lifelong commitment, and everyone has their own reasons to become tattooed, whether they be simply esthetic or a proclamation of group identity. Tattoos are representations of one’s feelings, unconscious conflicts, and inner life onto the skin. The skin plays a major role in this representation and is involved in different ways in this process. This article aims to review the historical and psychoanalytical aspects of tattoos, the reasons for and against tattooing, medical and dermatological implications of the practice, and emotional reflections from a psychodermatological perspective.

A formal approximate solution is derived for the profile and velocity components of a wave with permanent form of finite height m moderate water depths. The approximation is carried to the third order, sufficiently far to represent all except the very high "design" waves. The relationship of the formulas to others found in the literature is discussed. The wavelengths and the coefficients in the third-order series for the wave profile, and the water particle velocities and local accelerations are tabulated for approximately 2000 waves. The depths, heights, and periods for the listed wave conditions vary respectively from 10 to 500 feet, 5 to 40 feet, and 4 to 20 seconds. The range of applicability of the theory is discussed and approximate limits estimated. As an aid in calculations, tables of the trigonometric and hyperbolic sines and cosines for integral multiples of the argument are included.

The aim – to determine the factors associated with the frequency of hospitalizations for decompensation of heart failure (HF) after cardiac surgery in patients with valvular heart disease. Materials and methods. 235 patients who underwent cardiac surgery for valvular heart disease were examined. During the period from 2014 to 2017, a part of patients (129 people) had no hospitalizations, while 106 people were on inpatient treatment from 1 to 10 times, on average 2.78±1.95. The complex of examination of patients along with physical examination included electrocardiography, echocardiography. Results and discussion. During dynamic observation for 2 years in the group of patients without hospitalization, a progressive statistically significant decrease in the size of the left atrium (LA) and left ventricle (LV) as well as an increase in LV contractility were noted, while in the group of patients after hospitalization such changes were not observed. The dimensions of the chambers of the heart remained practically unchanged for 2 years. Thus, it can be concluded that the more severe course of heart failure after prosthetics of heart valves is accompanied by the absence of reverse remodeling of the heart chambers. Predictors of hospitalizations for HF are the presence of diabetes mellitus, hypertension and permanent form of atrial fibrillation. Conclusions. The probability of progression of heart failure in patients after cardiosurgical intervention for valvular heart pathology is not affected by sex, age, type of lesion of the valve, etiology of valve damage, indicators of echocardiography. Predictors of hospitalizations for heart faiure in the long-term postoperative period are the presence of diabetes, AF, and AH. The more severe course of heart failure after prosthetics of heart valves is accompanied by the absence of reverse remodeling of the heart chambers.


A general method is presented for the exact treatment of analytical problems that have solutions representing solitary waves. The theoretical framework of the method is developed in abstract first, providing a range of fixed-point theorems and other useful resources. It is largely based on topological concepts, in particular the fixed-point index for compact mappings, and uses a version of positive-operator theory referred to Frechet spaces. Then three exemplary problems are treated in which steadily propagating waves of permanent form are known to be represented. The first covers a class of one-dimensional model equations that generalizes the classic Korteweg—de Vries equation. The second concerns two-dimensional wave motions in an incompressible but density-stratified heavy fluid. The third problem describes solitary waves on water in a uniform canal.
