Published: November 2019

Salmonella and E.coli possess different surface protein structures that can induce protective immune responses. Identification of these proteins capacitates development of diverse applications in prevention and diagnosis that contribute to effectively control disease-causing enterobacteria pathogens such as Salmonella and E.coli. A simple procedure for obtaining protein complexes of Salmonella serotypes and E.coli is performed in this study. A sonication process with heat treatment of whole bacteria induced the release of protein complexes. Concentration of the protein extract was quantified using protein quantification Kits-Rapid, and protein complex profile was obtained by SDS-PAGE (Sodium dodecyl sulfate polyacrylamide gel electrophoresis) and silver staining. The concentrations of protein ranged from 29.45 to 45.35 µg/mL in the Salmonella protein extracts, and from 25.35 to 36.72 µg/mL in the E.coli protein extracts. Six major groups of proteins from E. coli (YfiO, NipB, OmpF, YfgL, Talc, YaeT) and four major groups of proteins from Salmonella (Flagellin, OmpA, Porin, SEF21) were preliminarily determined by a simple procedure of extraction based on the molecular weight.

Published: November 2019

The methane-hydrogen fraction is a gaseous hydrocarbon by-product during oil processing for obtaining petroleum products. Until recently, the methane-hydrogen fraction was used as furnace oil in internal technological processes at a refinery. Some of the low-calorie methane-hydrogen fraction was burned in flares. Driven by the prospect of the methane-hydrogen fraction use as a fuel alternative to natural gas for burning in thermal power plants boilers, it became necessary to study the methane-hydrogen fraction combustion processes in large volumes. The conversion of ON-1000/1 and ON-1000/2 furnaces from the combustion of the methane- hydrogen fraction with combustion heat of 25.45 MJ/m3 to the combustion of the composition with combustion heat of 18.8 MJ/m3 leads to a decrease in temperature in the flame core for 100 °C as an average. The intensity of flame radiation on the radiant tubes decreases. Therefore, the operation of furnaces during combustion of methane-hydrogen fraction with a low heat of combustion at the gas oil hydro-treating unit is carried out only with a fresh catalyst, which allows lower flame temperatures in the burner.The experiments to determine the concentration of nitrogen oxides NOx and the burning rate w of the methane-hydrogen fraction in the ON-1000/1 furnace and natural gas in the TGM-84A boiler, depending upon the heat of combustion Qnr were carried out. The obtained results showed that the increase in the hydrogen content Н2 from 10.05 % to 18.36% (by mass) results in an increase in the burning rate w by 45%. The burning rate of natural gas with methane CH4 content of 98.89% in the TGM-84A boiler is 0.84 m/s, i.e. it is 2.5 times lower than the burning rate of the methane- hydrogen fraction with H2 content of 10.05%. The distributions of heat flux from the flame qf over the burner height h in the TGM-84A boiler were obtained in case of natural gas burning and calculation of burning of the methane-hydrogen fraction with a hydrogen content of 10.05% and methane of 28.27%. The comparison of the obtained data shows that burning of methane- hydrogen fraction causes an increase in the incident heat flux qf at the outlet of the burner.

Published: November 2019

The objects of the study were the Doy Chemical hollow-fiber ultrafiltration membranes which were use for preparation of make-up water for the Novocherkasskaya Regional Thermal Power Plant (RTPP).We tried out a possibility of applying the X-ray fluorescence spectrometry to study the condition of the spent non-recoverable ultrafiltration membranes in order to identify the causes of their irreversible destruction. The ARL Quant’X X-ray fluorescence energy dispersive spectrometer of Thermo Scientific (USA) was used in the study.Thin cuts of the Doy Chemical hollow-fiber ultrafiltration membranes were used in the experiments, which had worked for more than three years in the field conditions of the feed water of the Don River, Russia.The analysis of the obtained samples spectra allowed us to assume that the membranes were irreversibly contaminated by iron bacteria. Basing on the conclusions made during the analysis of X-ray fluorescence spectra we developed and tested in field conditions one of the optimization variants for technological pretreatment scheme. This scheme enables a significant increase in the service life of ultrafiltration membranes, even when the feed water is heavily contaminated by bacteria. Field tests of the modernized technology were carried out at Novocherkasskaya RTPP during 2016-2018 and showed a significant increase in the service life of the membrane modules. At the same time, the quality of the filtrate, productivity and pressure drops at the cascades of ultrafiltration units fully corresponded to the normative values even in conditions of deteriorated quality of the feed river water.It has been proved that aggressive regeneration of ultrafiltration membranes that have worked for a long time under the conditions of feed water having increased values of the total microbial number and high values of permanganate oxidation does not allow one to restore their initial state. In this case the main cause of ultrafiltration membranes contamination is iron, which is present in colloidal and bacterial forms in the pores and on the membranes surfaces. In the conditions of the Novocherkasskaya RTPP, in addition to timely flushing and chemical regeneration of ultrafiltration membranes, the necessity of organizing a preliminary treatment of the feed water with reagents having a prolonged bactericidal effect is accepted.

WHAT WE HAVE LOST FROM WHAT HAVE BEEN DONE: ETHICAL PROBLEMS OF THE SALVAGED SHIPWRECK CARGOES IN INDONESIA
Authors: Putra Hutomo 
Published: November 2019

The struggling in the ethical issues of submerged underwater sites and underwater cultural heritage have been undertaking in Indonesia for the last two decades. During these 20 years, commercial companies in collaboration with the National Shipwreck Committee recovered and salvaged substantial numbers of material cargoes. Unfortunately, the majority of these operations occurred without the involvement of archaeologists and lack of proper and controlled archaeological methods and excavation techniques. Since 2010, the Indonesian Government has declared a moratorium that temporarily stopped all commercial survey and salvage activities, and prohibits the sale of the artefacts. Nowadays, more than 190,000 artefacts raised by salvagers are currently stored at the National Shipwreck Committee warehouses near Jakarta, in Cileungsi, West Java, Indonesia. This study attempts to illustrate the disadvantages of the commercial salvage practices and the auction of salvaged artefacts. This research also discusses some recommendations to contribute to a more ethical system of protection and the long-term management of the Indonesian maritime cultural resources, including its existing collections from salvaged shipwreck sites that are stored at the National Shipwreck Committee warehouse today.

The purpose of the work consists in the development of a simulation model of pad geometrical parameters and in definition of optimum modes for the method developed for the electric-arc direct layer growth of metal parts. The formation of a simulation model was carried out with the aid of CONSOL Multiphysics program complex. The result processing of experimental investigations was carried out by means of Compass-3D software support. For the definition of geometrical parameters of the pad grown there were welded samples with a consumable electrode in the environment of protective gases. Further there were microsections made of each sample in the transverse direction. The microsections cut out were ground, polished with the use of ASM 10/7 NVL diamond paste. For the definition of the microstructure the microsections were etched in 4% alcoholic solution of nitric acid.
The results obtained of the pad geometrical parameters are well correlated with experimental data. The error makes some 1…3%. On the basis of the model offered there is defined an optimum range for modes of electric-arc layer growth ensuring the required pad geometrical parameters. A pad height makes 3mm, a pad width – 3.5mm.

OBJECTIVEThe objective of this study was to describe and evaluate a new surgical procedure for the correction of coronal imbalance (CI) in adult spinal deformity patients, called the “kickstand rod” technique.METHODSThe authors analyzed the records of 24 consecutive patients with pediatric and adult spinal deformity and CI treated between July 2015 and October 2017 with a long-segment fusion and a kickstand rod. For the kickstand rod technique, an iliac screw was placed on the ipsilateral side of the trunk shift and connected proximally through a side-by-side domino link to the thoracolumbar junction; this rod was distracted to promote coronal plane balancing. Distraction occurred with the rod on the contralateral side locked in order to preserve sagittal correction. Radiographic and clinical analyses were conducted to evaluate the outcomes and possible complications of the kickstand rod technique.RESULTSThe mean age of the patients was 55 years (range 14–73 years). Eighteen of the 24 patients were female. CI preoperatively was a mean of 63 mm, and the mean measurement at the final follow-up (mean duration 1.4 years) was 47 mm. There were no neurological, vascular, or implant-related complications in any of the patients. One patient developed wound dehiscence that was successfully treated without implant removal, and one developed proximal junctional kyphosis requiring extension of the construct proximally. One patient also returned to the operating room for excision of a spinous process. There were no complaints about screw prominence, kickstand construct failure, or significant worsening of CI after surgery.CONCLUSIONSThe kickstand rod technique is safe and effective for the correction of CI in spinal deformity patients. This technique was found to provide marked coronal correction and additional strength to the overall construct without significant adverse consequences.
Asymptotic behaviour for an equation of superslow diffusion in a bounded domain
Authors: Galaktionov Victor A. , Kersner Róbert , Vazquez Juan L. 
Published: November 2019

We study the large-time behaviour of the solution to the mixed problem: ut=Δ(e−1/u) in Q=Ω×(0,∞), with u(x, t) = 0 for x∈∂Ω, t≥0 and u(x,0)∈L∞(Ω), u(x,0)≥0. Ω is a bounded domain with smooth boundary ∂Ω. We show that there exists a function F(x) > 0 in Ω such that as t→∞ t(log t)2e−1/u→F(x) uniformly in x∈Ω. The function F is uniquely determined as the solution of the problem: ΔF=−1 in Ω, F=0 on ∂Ω.

In this paper we study the asymptotic behaviour of the functionals Fε(u)=∫Ω[ε|∇u|2+ε−3β(u/ε)]dx where β is a non-negative lower semicontinuous function with compact support. When ε tends to 0, the limit functional corresponds to a least area problem with an obstacle.
Asymptotic representation of elastic fields in a multi-structure
Authors: Kozlov V.A. , Maz'ya V.G. , Movchan A.B. 
Published: November 2019

A mixed boundary value problem is posed for the Lame system in an elastic multi-structure which consists of a union of a three-dimensional domain and thin cylinders. A normalized thickness of a rod is characterized by a small parameter ε. We present a rigorous algorithm which yields a multi-scaled asymptotic expansion for the displacement and stress fields in the multi-structure. Justification of the asymptotic algorithm, including the remainder estimate for the asymptotic approximation of the displacement field, is given. The asymptotic analysis provides the range of applicability of the engineering pile structure model. It is shown that first three eigenvalues of the spectral problem in the above multi-structure have the order O(ε4). The asymptotic formulae for these eigenvalues are obtained.
Regularity and integrability of 3D Euler and Navier–Stokes equations for rotating fluids
Authors: Babin A. , Mahalov A. , Nicolaenko B. 
Published: November 2019

We consider 3D Euler and Navier–Stokes equations describing dynamics of uniformly rotating fluids. Periodic (as well as zero vertical flux) boundary conditions are imposed, the ratios of domain periods are assumed to be generic (non-resonant). We show that solutions of 3D Euler/Navier–Stokes equations can be decomposed as U(t,x1,x2,x3)=Ũ(t,x1,x2) +V(t,x1,x2,x3)+r, where Ũ is a solution of the 2D Euler/Navier–Stokes system with vertically averaged initial data (axis of rotation is taken along the vertical e3). The vector field V(t,x1,x2,x3) is exactly solved in terms of the phases Ωt, τ1(t) and τ2(t). The phases τ1(t) and τ2(t) explicitly expressed in terms of vertically averaged vertical vorticity curl Ū(t)·e3 and velocity Ū3(t). The remainder r is uniformly estimated from above by a majorant of order a3/Ω, a3 is the vertical aspect ratio (shallowness) and Ω is non-dimensional rotation parameter based on horizontal scales. The resolution of resonances and a non-standard small divisor problem for 3D rotating Euler are the basis for error estimates. Contribution of 3-wave resonances is estimated in terms of the measure of almost resonant aspect ratios. Global solvability of the limit equations and estimates of the error r are used to prove existence on a long time interval T* of regular solutions to 3D Euler equations (T*→+∞, as 1/Ω→0); and existence on infinite time interval of regular solutions to 3D Navier–Stokes equations with smooth arbitrary initial data in the case of small 1/Ω.
