    Horndeski Genesis: strong coupling and absence thereof

    Full text link
    We consider Genesis in the Horndeski theory as an alternative to or completion of the inflationary scenario. One of the options free of instabilities at all cosmological epochs is the one in which the early Genesis is naively plagued with strong coupling. We address this issue to see whether classical field theory description of the background evolution at this early stage is consistent, nevertheless. We argue that, indeed, despite the fact that the effective Plank mass tends to zero at early time asymptotics, the classical analysis is legitimate in a certain range of Lagrangian parameters.Comment: 10 pages, 1 figur

    Safety working out water-soluble ore fields in many ways depends on the stability of chamber development system`s elements. To monitor the interchamber pillars` status a method of experimental and theoretical evaluation of the geomechanical processes taking place in the array was developed, the essence of which lies in the meaningful results interpretation of mechanical characteristics and the stress state experimental studies of load-carrying structures by mathematical modeling methods. The article describes the method of estimating the marginal rock array`s stress state. The tension control was made using an acoustic memory effect. The measurements were performed in the wells with the help of a Goodman hydraulic jack. Its feature is the ability to create a load on the borehole array in the same plane, that allows to evaluate the stress magnitude in various directions. During the loading of the measuring borehole walls there is a discontinuous increase in the activity of acoustic emission. The pressure, which is logged in the hydraulic system, was taken at the level of the natural stresses acting in the marginal array. As a result of complex laboratory and field studies methodological features of stress analysis were identified using memory effects in salt rocks of the Verkhnekamskoye potash salt deposit. The experimental data analysis showed that in the β€œfresh” interchamber pillars a bearing pressure maximum is located near the contour of exposure and in 1.8-2.0 times higher than the load of of the overlying rocks` weight (gH). In the central part of the pillar the vertical stress level is 1.25-1.4 gH. With the increase in pillars` service life the marginal array`s stresses magnitude declines to the stress level of the overlying rocks weight. The horizontal stress increases with moving from the pillar contour and are approximately 60-70% of the vertical. These instrumental measurements results are a source data for assessing the long-term sustainability of interchamber pillars in sylvinite layers mining

    The polymer compositions on the base of acrylic derivatives and bentonite particles modified by silver ions with various share and dispersion are received and studied by radical polymerization in the water. Partially neutralized acrylic acid, acrylamide and methylene-bis-acrilamide and particles of bentonite with fraction 0 - 0,05 mass.% are chosen as initial substances. The influence of bentonite concentration on absorbing characteristics of polymer materials in the distilled water is shown. It is demonstrated that the increase of bentonite fraction up to 5 mass.% leads to the rise of degree of equilibrium swelling by 1,5 – 2 times in comparison with an unfilled polymer matrix. The acrylic nanocompositions with a mass fraction of bentonite equal to 0,01 mass.% possess the greatest kinetic characteristics. Kinetic dependences of new composite materials swelling in physiological solution from a filler dispersion part are investigated. It is shown that in high dispersion (with particle size less than 0,25 mm) a part of mineral–containing filler equal to 1 mass.% leads to significant increase in values of equilibrium swelling degree in comparison with an unfilled sample (by 1,5 times). The effect of polyelectrolyte suppression of polymer composition swelling in physiological solution is studied. It results in values reduction of equilibrium swelling degree in comparison with these values in the distilled water. Application prospects for the received compositions are shown at bandages creation for wounds treatment of various etiologies. Research results are recommended for usage in medical practice for optimization of wound process march

    Purpose: to study the dynamics of blood plasma electrochemical parameters in patients with severe combined trauma before and after fresh frozen plasma (FFP) transfusions.Materials and methods. The open circuit potential (OCP) of platinum electrode and antioxidant activity of blood plasma were studied in 35 patients with severe combined trauma and 35 post-FFP samples with at least 6-month shelf life. The electrochemical parameters of patients’ blood plasma were analyzed before transfusion, and 1 hr. and 24 hrs. after transfusion.Results. OCP measured in FFP was found to be more positive vs. OCP measured in recipients' blood plasma in 34 out of 35 cases (97%). It has been shown that in patients with severe combined trauma, OCP increased from 5.047 [-7.553; 12.976] mV to 12.827 [-1.372; 24.764] mV and antioxidant activity decreased 24 hours after FFP transfusion from 16.979 [11.302; 20.946] Β΅C to 13.551 [9.288; 18.405] Β΅C. After FFP transfusion, there were no significant changes in clinical blood parameters.Conclusion. By measuring electrochemical parameters of blood plasma in patients with severe combined trauma before and after FFP transfusions, it was discovered that in spite of absence of changes in blood parameters by routine methods, there are changes in the condition of the antioxidant system of the body, which manifest in the bias of patients’ blood plasma OCP towards higher positive values and decreased antioxidant activity. Redox imbalance in the body might cause the oxidative stress development.ЦСль исслСдования: ΠΈΠ·ΡƒΡ‡ΠΈΡ‚ΡŒ измСнСния элСктрохимичСских ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€ΠΎΠ² ΠΏΠ»Π°Π·ΠΌΡ‹ ΠΊΡ€ΠΎΠ²ΠΈ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с тяТСлой сочСтанной Ρ‚Ρ€Π°Π²ΠΌΠΎΠΉ Π΄ΠΎ ΠΈ послС трансфузий свСТСзамороТСнной ΠΏΠ»Π°Π·ΠΌΡ‹ (Π‘Π—ΠŸ).ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    Β The main goal in the treatment of kidney tumors is to preserve renal function. Investigations made in the past decades show that chronic kidney diseases (CKD) are much more common than formerly estimated and conventional methods for evaluating renal function frequently reduce the incidence of CKD having more serious consequences than recognized before. CKD leads to renal dysfunction subsequently resulting in renal failure that increases a risk for the development and progression of cardiovascular diseases. Formulas for calculation of glomerular filtration rate on the basis of serum creatinine are presently in common use to evaluate renal function. The MDRD and Cockcroft-Gault formulas are most frequently used. Investigations dealing with the radiological estimation of renal volumes and function are also promising. In patients with renal cell carcinoma (RCC), the differences in cancer-specific and overall survival become significant just 3 years after surgery. Decreased renal function after surgical renal tissue removal in the presence of CKD is one of the significant reasons for no positive changes in the overall survival of patients with RCC. According to the data of different studies, the concurrence of RCC and CKD, which cause diminished renal function, is encountered in a considerable number of patients. Thus, the present-day treatment of patients with RCC should be focused on the optimization of renal function, the prevention of CKD, and the minimization of its degree. Researches to improve renal function in RCC patients who have undergone surgery are regarded as the priorities of urologic oncology.Π‘ΠΎΡ…Ρ€Π°Π½Π΅Π½ΠΈΠ΅ ΠΏΠΎΡ‡Π΅Ρ‡Π½ΠΎΠΉ Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΈ являСтся основной Π·Π°Π΄Π°Ρ‡Π΅ΠΉ Π² Π»Π΅Ρ‡Π΅Π½ΠΈΠΈ ΠΎΠΏΡƒΡ…ΠΎΠ»Π΅Π²Ρ‹Ρ… Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ ΠΏΠΎΡ‡Π΅ΠΊ.
