Integration Challenge

The paper is devoted to the analysis of development prospects and problems of Eurasian Economic Union (EAEU) of Russia, Kazakhstan, Belarus and Armenia. It considers integration problems inside EAEU, interactions of EAEU with other CIS countries and with countries from the rest of the world. The paper shows that the major integration challenge inside EAEU is the domination of the redistributive motive over the creative one. It estimates the value of the oil and gas transfer from Russia to other EAEU members and the influence of the Russian tax maneuver on this transfer. The paper shows the need in redistribution mechanism inside EAEU as a necessary condition for getting the potential positive economic effects of free trade with other countries. It also assesses the risks for EAEU due to Russian embargo for food imports from countries of the sanctions list and possible application of tariff in the trade with Ukraine.

Abstract. Early rehabilitation (ER) of patients with acute cerebrovascular accident (ACA) is one of the priority tasks of the vascular centers; the issue of increasing the volume of rehabilitation measures in the resuscitation and intensive care units (ICU) is relevant. Objective. To evaluate the safety and effectiveness of the progressive ER program in patients with ACA. Material and research methods. The study included 129 patients with ACA in ICU. Each patient of the main group (MGr, n = 61) underwent progressive ER: at least 4–5 vertical adjustments per day, passive mode Kinesiotherapy 49 ± 9.3 minutes, a double load of physiotherapy exercises, preventive physiotherapy; the total time of classes reached 240 minutes per day. In the comparison group (СGr, n = 68), standard ER was performed no more than 120 minutes per day. The groups are comparable by sex, age, severity of the disease and comorbidity. The severity of ACA, the gravity gradient, patient mobility, functional status, degree of dependence, and the presence of complications were evaluated. Results. During a month of work with the MGr, 102 ICU bed-days, 94 days of the artificial lung ventilation use, p < 0.05 were saved. Mortality in MGr decreased -— 8 patients (13.1%) versus 14 (20.6%) in CGr (p < 0.05). In patients within CGr, pulmonary thromboembolism developed in 8.8%, in MGr – in 3.3%. The severity of the apoplectic attack decreased ( by 28% in MGr, and by 20% in CGr ), mobility increased. Comparing the modalities of post resuscitationsyndrome in MGr, it was noted that the score decreased by 2 times from 6 [5; 6] to 3 [2.3; 3.3], but it has not changed in the CGr. Patients in the MGr were 2-–3 days earlier adapted to the vertical adjustment. Conclusions. The progressive ER program in ICU is safe, effective, realisable, and allows reducing the number of bed-days in ICU, the number of days of the artificial lung ventilation use, complications, and mortality in comparison with standard medical care.

Trickle Bed

Catalytic activity of CuO-supported catalyst in phenol oxidation, and the influence of reaction conditions, viz. temperature (125-170 °C), oxygen partial pressure (1-7 MPa) and liquid feed (30-760 ml h-1), in the continuous operation using 17.9 mm i.d. trickle-bed reactor is presented. The hydrodynamic impact on the three-phase trickle-bed reactor performance in an environmental application of catalytic wet oxidation was also investigated. The results of trickle-bed operation were strongly influenced by wetting efficiency. An insufficient catalyst wetting can be to compensated by filling the catalyst bed voids by fine glass spheres. In the case of the gas transfer limited reaction, a better wetting of the catalyst can lead to worse reactor performance due to lower reaction rates.
