This p.p.r p.esents theoretical and exp.rimental studies on the magnetodynamics and energy absorp.ion in a dilute susp.nsion of small ferromagnetic p.rticles with magnetic hysteresis and mechanical mobility in an AC magnetic field. Exp.riments with 0.1% susp.nsions of acicular p.rticles of gamma ferric oxide in solid and liquid matrices, subjected to a 430 Hz magnetic field with an intensity of up.to 1200 Oe, revealed imp.rtant role of p.rticle mobility. The main qualitative and quantitative features of the p.enomenon are in agreement with a model of joint magneto-mechanical dynamics of p.rticles with a chain-of-sp.eres mode of incoherent magnetic reversal.

Rutting of asp.alt p.vements is a crucial design criterion in various p.vement design guides. A good road transp.rtation base can p.ovide security for the transp.rtation of oil and gas in road transp.rtation. This study attemp.s to develop.a robust artificial intelligence model to estimate different asp.alt p.vements’ rutting dep.h clip., temp.rature, and load axes as p.imary characteristics. The exp.riment data were obtained from19 asp.alt p.vements with different crude oil sources on a 2.038km long full-scale field accelerated p.vement test track(Road Track Institute, RIOHTrack) in Tongzhou, Beijing. In addition,this p.p.r also p.op.ses to build comp.ex networks with different p.vement rutting dep.hs through comp.ex network methods and the Louvain algorithm for community detection. The most critical structural elements can be selected from different asp.alt p.vement rutting data, and similar structural elements can be found. An extreme learning machine algorithm with residual correction(RELM) is designed and op.imized using an indep.ndent adap.ive p.rticle swarm algorithm. The exp.rimental results of the p.op.sed method are comp.red with several classical machine learning algorithms, with p.edictions of average root mean squared error(MSE), average mean absolute error(MAE), and a verage mean absolute p.rcentage error(MAp.) for 19 asp.alt p.vements reaching 1.742, 1.363, and 1.94% resp.ctively. The exp.riments demonstrate that the RELM algorithm has an advantage over classical machine learning methods in dealing with non-linear p.oblems in road engineering. Notably, the method ensures the adap.ation of the simulated environment to different levels of abstraction through the cognitive analysis of the p.oduction environment p.rameters. It is a p.omising alternative method that facilitates the rap.d assessment of p.vement conditions and could be ap.lied in the future to p.oduction p.ocesses in the oil and gas industry.

Objectives. Using of systemic ozone therap. connecting with antioxidants in early p.riod of burn disease for detoxication and metabolic disorders correction is investigated. Materials and Methods. We used active p.eventive metabolic detoxication in early p.riod of burn disease (5th - 15th days after shock stage). It includes, besides comp.ex infusion and transfusion therap. and classic p.armacological treatment, emp.oyment of antioxidants with succinic acid (reamberin, mexidol), systemic ozone therap. (intravenous injections of ozonated sodium chloride solution with ozone concentration 120 - 240 μg/mL;saturating ozone concentration in gas flow—5000 μg/L, sp.rging sp.ed—2 l/min), major autohemotherap. (twice a week;ozone dose—250 - 300 μg/mL) and monitor cleansing of bowels with rectal ozone insufflations (ozone dose—1000 μg/mL). Estimation of p.rsonal oxidant dose and treatment effectiveness is carried out by biochemiluminescence control of p.o- and antioxidant system state. Comp.ex p.tient study also includes endotoxicosis markers (blood level of glucose, creatinine, bilirubin, urea and intermediate molecular weight p.p.ides), p.oteolytic enzymes activity (trip.in, antitrip.in, elastase), cardiovascular and microcirculation function examination (tetrap.lar rheograp.y, sp.rograp.y, laser Dop.ler flowmetry) at burn disease dynamics. We formed two p.tients group.: first control group.(20 burned p.tients) received a traditional therap.;second group.(20 burned p.tients) got a described detoxication comp.ex additional to treatment of first group. All p.tients had large burns (more than 20% body square). Indications for p.renteral ozone therap. are signs of hyp.xia (hyp.xemia, elevated lactate level, dep.essed lactate dehydrogenase activity) and toxemia (increased blood level of glucose, creatinine, urea, intermediate molecular weight p.p.ides, fibrine degradation p.oducts, lyp.p.roxidation intensification);cardiovascular dysfunction;resp.ratory function disorders.

Objective: To determine the effect of a drug STEMB, which is a biostimulating tissue p.ep.ration based on chicken embryos, on the morp.o-biochemical blood values of dry cows. Methods: The study was conducted on 60 Holstein cows, which were divided into three group. (group.1, group.2, and group.3), with 20 cows in each group. During the exp.riment, all animals in each group.were subjected to the same condition of feeding and maintenance. The exp.rimental animals were administered with the STEMB drug three times subcutaneously at an interval of 7 d within 30 d before calving. Group.1 were given 0.050 mL/kg body weight;group.2 were given 0.075 mL/kg body weight;group.3 were given 0.100 mL/kg body weight. Results: STEMB at 0.075 mL/kg body weight imp.oved the blood cell comp.sition, increasing the erythrocytes, hemoglobin, leukocytes, hemoglobin content, the total p.otein, albumins, alp.a globulins, and gamma globulins. It reduced the beta-globulin index and p.ovided a threshold level for the enzymes alanine aminotransferase, asp.rtate aminotransferase, and A, M, G immunoglobulins. Conclusions: Use of the STEMB drug with a dose of 0.075 mL/kg body weight given subcutaneously three times at an interval of 7 d within 30 d before delivery is op.imal for the p.evention of comp.ications during calving and p.stp.rtum p.riods, thereby p.oviding an imp.ovement in the blood cell comp.sition.
