The results of investigation on synthesis of the layered composites "ferromagnetic-ferroelectric " for usage as an active dielectric of the impulse current and voltage generators' forming lines are presented. The structure of composites with simultaneous change of their effective permittivity and permeability to achieve almost constant wave impedance of the forming line at electromagnetic waves propagation are proposed. The technological methods, which provide obtaining the layered composites samples by cold pressing, are described.

To compare the efficacy of simo decoction (SMD) combined with acupuncture at the tsusanli acupoint or chewing gum alone for treating postoperative ileus in patients with hepatocellular carcinoma (HCC) after hepatectomy.In postoperative ileus, a frequent complication following hepatectomy, bowel function recovery is delayed, which increases length of hospital stay. Studies suggest that chewing gum may reduce postoperative ileus; SMD and acupuncture at the tsusanli acupoint have long been used in China to promote bowel movement.Patients with primary HCC undergoing hepatectomy between January 2015 and August 2015 were randomized to receive SMD and acupuncture (n = 55) or chewing gum (n = 53) or no intervention (n = 54) starting on postoperative day 1 and continuing for 6 consecutive days or until flatus. Primary endpoints were occurrence of postoperative ileus and length of hospital stay; secondary endpoints were surgical complications.Groups treated with SMD and acupuncture or with chewing gum experienced significantly shorter time to first peristalsis, flatus, and defecation than the no-intervention group (all P < 0.05). Hospital stay was significantly shorter in the combined SMD and acupuncture group (mean 14.0 d, SD 4.9) than in the no-intervention group (mean 16.5 d, SD 6.8; P = 0.014), while length of stay was similar between the chewing gum group (mean 14.7, SD 6.2) and the no-intervention group (P = 0.147). Incidence of grades I and II complications was slightly lower in both intervention groups than in the no-intervention group.The combination of SMD and acupuncture may reduce incidence of postoperative ileus and shorten hospital stay in HCC patients after hepatectomy. Chewing gum may also reduce incidence of ileus but does not appear to affect hospital stay. (Clinicaltrials.gov registration number: NCT02438436.)

Abstract The eastern margin of the Chitradurga schist belt is marked by a NNW-SSE trending subvertical crustal scale ductile shear zone The kinematic indicators indicate a predominant sinistral sense of strike-lip movement along the shear zone Syntectonically emplaced granitic rocks are converted to mylonites and ultramylonites as a result of crystal-plastic deformation in the shear zone In contrast, there are localized zones of brittle failure with attendant frictional heat generation exemplified by the development of thin but conspicuous bands and veins of pseudotachylytes, which are emplaced either subparallel with or transgressing the C-planes of the mylonites From our field and petrographic studies it is interpreted that these two coexisting rock types, namely the mylonite and pseudotachylyte, which are the results of contrasting deformational mechanisms, have generated near synchronously in a progressively developed ductile shear zone The pseudotachylytes represent the brief interlude of sudden increase in strain rate in an overall ductile regime
