The economic efficiency of NPP power units’ life extension in excess of the specified service life is shown. Some information on the extension of Kola NPP power units with VVER-440 service life up to 60 years in terms of improving security is given. Показана экономическая эффективность продления срока эксплуатации энергоблоков АЭС сверх установленного срока. Приведены некоторые данные по продлению срока эксплуатации энергоблоков Кольской АЭС с ВВЭР-440 до 60 лет с точки зрения повышения безопасности.

Наибольшее количество пожаров происходит в жилом секторе. Одной из распространенных причин этих пожаров является неосторожное обращения с тлеющими табачными изделиями. Сигареты марки Winston пользуются наибольшим спросом пользуются в России. Определены температура и средняя скорость тления сигарет марки Winston XS. Найдено, что определенные значения скорости тления согласуется с результатами, полученными по методу ГОСТ ИСО 12863–2013. The greatest number of fires occur in the residential sector. One of the common causes of these fires is the careless handling of smoldering tobacco products. Winston brand cigarettes are most in demand in Russia. The temperature and average smoldering speed of Winston XS cigarettes are determined. It was found that certain values of the speed of smoldering are consistent with the results obtained by the method of GOST ISO 12863–2013.

The expediency of extending the lifetime of NPP power units beyond the design life is justified. The principle of continuous incremental safety improvement due to modernization is updated. Ways toreduce the cost of doses during the extension of the service life are considered. Обоснована целесообразность продления сроков эксплуатации энергоблоков АЭС сверх проектного ресурса. актуализирован принцип непрерывного поэтапного повышения безопасности за счет модернизации. Рассмотрены пути снижения дозовых затрат при продлении срока эксплуатации.

Aim. To investigate the diagnostic potential of cardiac fatty acid binding protein (cFABP) vs. cardiac troponins at the early stages of acute coronary syndrome (ACS), by comparing specificity and sensitivity of the qualitative assessment of their blood levels. Material and methods. The independent Russian multi-centre study ISPOLIN (Clinical effectiveness of early acute myocardial infarction diagnostics, based on the assessment of cFABP levels) included 1049 patients, who were hospitalised with possible ACS diagnosis, within 1–12 hours from the clinical onset. At admission, all participants underwent a qualitative assessment of cFABP and troponin I (TrI) blood levels. For each test, sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) were examined for the whole sample, as well as by gender, age, body mass index (BMI), test time, and electrocardiographic (ECG) changes. Results. The sensitivity of cFABP test was higher than that for TrI (73,8% vs. 46,7%, respectively). Specificity reached 92% and 97,2%, respectively. Respective accuracy values were 79,3% and 62,2%. PPV was 0,95 for cFABP and 0,97 for TrI, while NPV was 0,61 and 0,45, respectively. The maximal sensitivity of cFABP test was observed within 3–6 hours from the onset of acute myocardial infarction, and exceeded the sensitivity of TrI test by 18–32% at all examined time points. Regardless of the ECG change type, sensitivity of cFABP test was higher than that of TrI test by 19–73%. For both tests, sensitivity and specificity did not correlate with age, gender, or BMI. Conclusion. Within the first 12 hours from the clinical onset of possible ACS, a Russian express test, which qualitatively assesses cFABP levels, demonstrated higher sensitivity, accuracy, and NPV, compared to the TrI test. The cFABP test can, therefore, be recommended for a wider use in clinical practice.

The paper focuses on the effectiveness and safety of bi- and monophase defibrillators in patients with paroxysmal atrial fibrillation. In bi-phase defibrillator cardioversion, sinus rhythm was restored more often, and total defibrillation energy was substantially lower than in monophase defibrillator cardioversion. No significant differences in myocardial necrosis markers were observed.

We present specific-heat, elastic constants, and magnetic susceptibility measurements in a ferromagnetic Ni 2 MnGa Heusler alloy, in a temperature range where partial condensation of the [110] TA 2 phonon at q=0.33, accompanied by the development of a micromodulated structure has been reported to occur. All these quantities have been found to exhibit anomalous behavior at the temperature of condensation. From the results presented, it can be concluded that the appearance of the micromodulated structure takes place via a phase transition which is very weakly first order. It is found that at the transition point there is a significant reduction of the dynamical stability of the lattice not just for the transverse phonon at q=0.33, but also for any shear long wavelength distortion. It is particularly remarkable the large softening of C′ (around 60%) at the transition point. Finally, it is also shown that the intermediate transition is related to a magnetoelastic interaction.
