The control system for the detectors of the SPASCHARM experimental setup that is being developed at the U-70 accelerator complex (Protvino) is described. The general design concept of the control ...system and an example of application of the EPICS software are considered. The electronic modules of the control system that have been put in operation as of the present are described.
The structural evolution of the Late Precambrian and Early to Middle Paleozoic complexes is considered for the southern part of the Uraltau Zone and its extension in the Ebeta Antiform, as well as ...for the northeastern and northwestern frameworks of the ophiolitic Khabarny Allochthon, where the Late Precambrian and Paleozoic complexes of the continental margin in combination with ophiolites are drawn together in packets of tectonic nappes. The formation of the regional structure took place during several stages in various geodynamic settings. Five deformation stages have been recognized in the regional structural evolution from new data on mesostructural parageneses, which consist of folds that developed within outcrops and their relationships in rocks differing in age. The first stage is related to the Late Precambrian Timanian, or Cadomian Orogeny, and four subsequent deformation stages characterize Paleozoic tectonic evolution of the region. The geodynamic nature of the second stage remains unknown; the third stage is related to overthrusting of ophiolites in the Early Devonian; the fourth stage of deformations marks Late Paleozoic continental collision. The fifth stage of postcollisional strike-slip deformations completes the regional structural evolution.
The diffraction method is used to study the properties of laser radiation interacting with a gas-cluster plasma. Based on the simulation of propagation a laser beam with a wavelength 800 nm through a ...hexagon Cu-mesh and subsequently compared with the obtained experimental diffraction pattern, the contribution of the second harmonic to the laser radiation was considered. The capability of this method to reveal the spectral composition of laser radiation is discussed. Also, the dependence of the visibility of the diffraction pattern on the intensity of the laser beam is considered. Besides, the contribution of x-ray radiation generated from the laser-cluster interaction into the observed diffraction pattern signal was estimated.
Based on objective criteria of the structural and functional state of the kidneys in various urgent surgical and uronephrological pathologies (peritonitis, pancreonecrosis, intestinal obstruction, ...urinary peritonitis, acute purulent secondary pyelonephritis) to identify and prove the general pattern of development of renal changes, their influence on the pathogenesis of homeostasis disorders at the organizational level and to form the evidence base of a new symptom complex - renal distress syndrome in surgery and uronephrology; to establish the effectiveness of Remaxol in its correction.
Experimentally on 60 mongrel dogs with acute peritonitis, pancreatitis, intestinal obstruction of varying severity, the state of renal function, including detoxification, was assessed based on the assessment of the inflow-outflow difference in the level of toxins and in the parenchyma of organs - the composition of lipids, the activity of peroxidation of membrane lipids and phospholipases. Clinical and laboratory studies included patients with acute peritonitis (48), acute pancreatitis (18), intestinal obstruction (21), acute purulent secondary pyelonephritis (19). Patients with peritonitis (20) underwent standardized therapy (the first subgroup) or with the inclusion of Remaxol (28) (the second subgroup).
In the experiment and in the clinic, in acute surgical and some urological diseases with a different nature of the inflammatory process, there is a significant decrease in renal function. The recorded acute renal injury is combined with a pronounced membrane-stabilizing process in the tissue structures of the kidneys, the degree of which is associated with the severity of the disease. In order to correct and stabilize the indicated changes, Remaxol was used. The drug increased kidney tolerance to trigger pathogenetic agents, which improved the functional status of the kidneys. These data confirm the significance of the studied molecular mechanisms in kidney damage in urgent pathology.
Experimental and clinical evidence has been obtained for the formation of a new concept - a symptom complex in acute surgical and uronephrological diseases of the abdominal cavity and retroperitoneal space called renal distress syndrome. Renal distress syndrome in surgery and uronephrology is a set of pathological processes of the body, the most important manifestation of which is the progression of endogenous intoxication due to a violation of the functional status of the kidneys as a result of membrane-stabilizing phenomena of organ cells due to oxidative stress and phospholipase activity.
