Comissioning of the linear accelerator-injector at the TNK facility

The industrial storage facility has been developed and manufactured at the Budker INP SB RAS. It contains an 80 MeV electron linear accelerator-injector and two electron storage rings: the lesser 450 MeV booster ring and the main 2.5 GeV storage ring. In 2002, the work on the accelerator assembling was begun. On December, 25 this year the accelerator was started up, and the current at the linear accelerator output was obtained. The linear accelerator schematic together with a description of the 6 meter long accelerating DAW structure which operates at 2.8 GHz, are presented in the paper. The first results of the accelerator start-up are as follows: the accelerated electron current of ~50 mA with the energy of ~55...60 MeV.Технологічний накопичувальний комплекс був спроектований і виготовлений у ІЯФ ім.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Hygienic assessment of habitat adverse social and sanitary factors in the Altai Krai

The materials on health status, socio-economic, sanitary living conditions of the population of the Altai Krai have been analyzed. The comparative analysis of the conditions of life and health outcomes in urban and rural settlements’ population has been performed. The estimation of health indicators’ correlation has been carried out in children of age group 0-1 years, children of age group 0-14 years, teens of age group 15-17 years and adults of age group over 18 years, depending on the type (urban or rural) of settlement with indicators of social and sanitary environmental factors. Regression equations for the health outcomes of different age groups on the level of hygiene and social environmental factors are set, regional critical (reference) values are justified. The hygienic assessment of unfavorable social, health and sanitation of the environment on the health of the population in the Altai Krai is provided

Resonance-like structure in ³⁶S(pγ)³⁷Cl reaction

The γ-decay of resonances forming resonance-like structure have been investigated in the ³⁶S(pγ)³⁷Cl reaction. The decay schemes have been established for the first time. The branching ratios and probabilities of direct γ-transitions have been determined. The assumption that these resonances belong basically to the states of the M1 resonance on the first excited state in ³⁷Cl has been stated. Position of the M1 resonance has been explained with the account of pairing forces.У реакції ³⁶S(pγ)³⁷Cl досліджено γ- розпад резонансів, що утворюють резонансноподібну структуру. Уперше побудовано схеми розпаду, встановлено коефіцієнти гілкування та імовірності прямих γ-переходів. Висловлено припущення про те, що ці резонанси належать в основному станам М1-резонансу на першому збудженому стані ядра ³⁷Cl. Положення М1-резонанса пояснюється з урахуванням сил спарювання.В реакции ³⁶S(pγ)³⁷Cl исследован γ-распад резонансов, образующих резонансно-подобную структуру. Впервые установлены схемы распада, определены коэффициенты ветвления и вероятности первичных γ-переходов. Высказано предположение о том, что эти резонансы принадлежат в основном состояниям М1-резонанса на первом возбужденном состоянии ядра ³⁷Cl. Положение М1-резонанса объясняется с учетом сил спаривания

Searching the analogue 2p₃/₂-resonance in the ³⁶S(p,γ)³⁷Cl reaction

Searching the analogue 2p₃/₂-resonance in ³⁷Cl, which is an isobaric analogue of the parent level with E* = 0.646 MeV (Jp = 3/2-) of ³⁷S was carried out. The excitation function for the ³⁶S(p,g)³⁷Cl reaction was measured in the energy region Ep = 2487 - 2680 keV. Resonance strengths were determined for 44 resonances. The decay schemes and branching ratios of four resonances were investigated at Ep = 2539, 2599, 2659 and 2676 keV. Spins and parities of these resonances (3/2⁺, 3/2⁺, 3/2⁺ and 5/2⁺, correspondingly) were established from angular distributions of γ-rays and measured intensities of γ-transitions
