Universality and Stability of the Edge States of Chiral-Symmetric Topological Semimetals and Surface States of the Luttinger Semimetal.

We theoretically demonstrate that the chiral structure of the nodes of nodal semimetals is responsible for the existence and universal local properties of the edge states in the vicinity of the nodes. We perform a general analysis of the edge states for an isolated node of a 2D semimetal, protected by chiral symmetry and characterized by the topological winding number N. We derive the asymptotic chiral-symmetric boundary conditions and find that there are N+1 universal classes of them.

[Modern methods of inhalation therapy of respiratory diseases].

In pulmonary practice the effectiveness of the therapy depends on a method of drug delivery. In case of different forms of medications, which can be used for the treatment of patients with obstructive pulmonary diseases physicians usually choose inhalants. In this publication authors examines the main aspects of the use of nebulizers in the treatment of obstructive pulmonary diseases: types of nebulizers, their capabilities and limitations, indications for inhalation therapy and drug policy.

[Pneumonia in wounded].

Pneumonia is one of the common complications of wounds of any localization. Therapists are involved into the treatment of lung lesions in wounded in the ICU, in the surgical and if the patient arrives "on follow-up care,"--in the medical ward. The article analyzes the main statistical indicators reflecting the prevalence and clinical and pathogenetic characteristics of lung pathology in wounded during the Great Patriotic War, during the fighting Soviet troops in the Republic of Afghanistan, the 1st and 2nd Chechen campaign.

[Epidemiology of prostate cancer (cohort study)].

The paper presents an analysis of morbidity and mortality from prostate cancer ("crude" and standardized rates), taking into account regional differences. The regularities of the dynamics of analytical rates are particularly observed.
