In recent years, there were published several epidemiological observations concerning the maximum incidence of hepatitis A (HA) shifting into the older age groups, including adolescents aged 15-19 and young adults 20-39 years old, and the reduction of the role of children as a significant risk group. These phenomena have not been sufficiently studied yet and have not received an adequate explan...

The np pair in the spin–singlet state is treated as a Cooper np–pair within the extension of the Nambu–Jona–Lasinio model of light nuclei, describing the deuteron as a Cooper np–pair in the spin–triplet state. For the Cooper np–pair in the spin– singlet state we compute the binding energy and express the S–wave scattering length of np scattering in the spin–singlet state in terms of the binding...

A B S T R ACT. This is a review of recent English-language scholarship on the development of Russian identity since the collapse of the USSR in 1991. The first part examines literature on the economic and political changes in the Russian Federation, revealing how scholars became more sceptical about the possibility of Russia building a Western-type liberal democracy. The second part investigate...

Mortality data, abstracted from the World Health Organization (WHO) database, are available for various countries. We used multiple myeloma mortality (ICD-10: C88–C90) in 11 countries during the period 1990–2006. These countries were Japan, China (Hong Kong) and the Republic of Korea (Asian countries); the United States of America (USA); Australia; the Russian Federation, the United Kingdom (UK...

The pharmacopoeial quality of non-expired and expired nifedipine tablets of the same batches purchased from the Estonian and Russian Federation medicinal product markets was evaluated. The IR spectroscopy, HPLC analysis for quantitative content and purity of the active pharmaceutical ingredient (API), and dissolution test techniques were applied. In the experiments with non-expired nifedipine t...

We compute the energy level displacement of the excited np states of kaonic hydrogen within the quantum field theoretic and relativistic covariant model of strong low–energy K̄N interactions suggested in EPJA 21, 11 (2004). For the width of the energy level of the excited 2p state of kaonic hydrogen, caused by strong low–energy interactions, we find Γ2p = 2meV = 3 × 1012 sec−1. This result is im...

AIM The purpose of the study was to evaluate the differences and factors that are interlinked with mortality rates of the population aged 40-59 years in the subjects of the Russian Federation. MATERIALS AND METHODS To calculate mortality rates used by Rosstat data on population and number of deaths in the age groups 40-59 years among men and women in the regions of Russia, as well as indicato...

Brazil, the Russian Federation, India, China and South Africa--the countries known as BRICS--represent some of the world's fastest growing large economies and nearly 40% of the world's population. Over the last two decades, BRICS have undertaken health-system reforms to make progress towards universal health coverage. This paper discusses three key aspects of these reforms: the role of governme...
