Authors: Korobko Grigory Ivanovich , Korobko Ivan Grigorievich , Shilov Maksim Petrovich
Published: November 2018

In modern electric engineering development and implementing autonomous diesel generator sets is considered as a new technological trend. The article focuses on the functional scheme of a diesel generator power station with variable frequency of rotation and control systems, the application of which will allow reducing fuel consumption. The main control units of the proposed variant of the autonomous power plant are a logic device and a synchronizer. After switching the diesel generator on the parallel operation, basic functions of the logic device are to estimate loading and issuing a task for diesel generators. On the basis of the obtained data, the tasks of controlling the state of the generator automaton for the diesel generator, which is in priority over the start/stop, are performed. To evaluate the efficiency criteria, a graph of load power variation is given depending on the power of diesel generators, in which the optimal load intervals are determined. Such a distribution allows achieving reduction in fuel consumption and cost of electricity, providing an increase in the economic performance of an autonomous power plant. Despite the fact that the autonomous power plant has limited power, the proposed variant provides a load reserve in the range 15-110% and overload capacity in the range 13-43% of the total power of the diesel generator with constant speed. A graph of fuel consumption change depending on the active power consumed is presented. The basic interval of work with the minimum consumption of fuel is defined. For comparison, curves are shown that reflect the efficiency of using a diesel generator with variable speed as compared to a unit operating at a constant speed.
CONTROL OVER LUBRICATION OF CYLINDERS ON MARINE LOW SPEED DIESEL ENGINES
Authors: Kuzmenko Georgy Vasilyevich , Panasenko Andrei Aleksandrovich
Published: November 2018

The article focuses on the problem of organizing control over oil supply to the cylinders of a marine diesel engines during slow speed operation. In the instructions for diesels with mechanical lubricators manufacturers strongly recommend to recalculate the actual specific oil consumption at share load and to reduce it to full operational load when evaluating oil consumption. The obtained specific oil consumption should be compared with the standard value, which was assigned for the full load regime. Manufacturers use different symbols for these parameters and different principles of oil supply regulation in their manuals. The variety of symbols and formulas makes it difficult to understand the technique, which is the reason why it is not applied on many vessels, as evidenced by the experience of certification of ship mechanics in the Maritime Qualification Commission of the port of Vladivostok. There have been proposed measures for wider application of the technique on ships, as it allows generalizing the experience of using oil on one-type engines in their operation on different types of ships with different load and practice to correct the recommendations about the cylinder oil dosage. Much attention is given to the features of the control organization over the lubrication of the cylinders on new generation ME S and G MK 8 type engines and later types with electronic control and regulation systems for continuous operation at super-low loads. When using a fuel with high sulfur concentration, these engines suffer from excessive wear of the cylinder bushings in their upper part due to acid corrosion because of hypernormal cooling of bushings. Therefore, the designers of diesel engines have developed special manuals on cylinder lubrication. There has been given the justification for applying the universal symbol qMR g/kW (h/kW) to indicate the initial rate of specific consumption of cylinder oil in relation to the full load of the marine low-rate diesels and the symbol qMR for “actual specific consumption reduced to a full load”. The details of oil dosage in the new generation S and G MK 8 type diesel engines are given, in which the effect of cold corrosion of bushes at low loads is manifested.
USE OF MEDIAN FILTERS IN PROCESSING EXPERIMENTAL DATA ON FLUCTUATION DYNAMICS OF FLOATING STRUCTURES OF VARIOUS TYPES
Authors: Gramuzov Evgeniy Mikhailovich , Ivanova Olga Aleksandrovna
Published: November 2018

The paper is devoted to the analysis of increasing the accuracy of the spectral characteristics obtained after processing experimental data of the vibrations of a physical model of the offshore drilling platform in the experimental tank. The increase in accuracy is provided by the recognition and correction of breakdowns and errors in the course of median filtering of vibration recordings of different positions of the platform relative to the propagation of waves in the tank and with different deepening of the platform support columns. The median filters are known to belong to nonlinear transformations; therefore, their characteristics are determined by the structure of their processing procedures. In this case, these are narrow-band, random oscillations with maximum spectra at wave frequencies, at fundamental frequency of the platform oscillation and harmonics, at frequencies that are multiple to the fundamental frequency. To use median filters in processing such signals, the amplitude-frequency characteristics of the median filter were determined as a function of the ratio of the characteristic period of oscillations to the equivalent filter base, i.e. to multiplying a number of points in the filter core by the discreteness of measurements. As a result, the condition for the effective application of median filtering in the processing of narrow-band random signals has been determined, which is used in analyzing the spectra of the processes under study. There are given characteristic examples of the spectra of angular oscillations (by roll and depth) of a semisubmersible platform with different drafts. It has been shown that at maximum draft, when the model is most stable, median filtering suppresses high-frequency noise components of the vibration spectra by 5-10 times and, at the same time, the main features of the spectra are not distorted, i.e. the main energy-carrying components are reproduced without visible distortion. In the other limiting case, with minimum platform draft, changes in the high-frequency part of the spectra are negligible due to increased intensity of angular oscillations. In this case, the oscillation spectra also reproduce the main features of dynamic processes. These data indicate the selective sensitivity of the median filter to the structure of the operating procedure and possibility of improving the accuracy of reproduction of spectral characteristics by suppressing the high-frequency noise components of a signal.
VORTEX RATIONAL (ENERGY-SAVING) HEAT EXCHANGE ENHANCEMENT IN NON-SIRCULAR DUCTS OF SHIP HEAT EXCHANGERS
Authors: Vasilev Viktor Yakovlevich
Published: November 2018

High demands placed to the quality of ship heat exchangers are determined by their outer dimensions and weight, power consumption for heat-transfer agents circulating, size of heat loading, operational availability, processability and manufacturing profitability. Lamellar-ribbed heat exchangers most successfully meet the listed requirements. Two methods of generating vortices (in the case of flow around poorly streamlined bodies and at divergent-convergent segments) in the wall layer of currents in rectangular ducts are realized in 10 plate-fin interrupted (PFTsm) heat transfer surfaces and in 31 tub-plate (TPsm) heat transfer surfaces (HTS) with cross ridges and grooves in order to determine the regularities of rational enhancement of convective heat transfer. The results of experimental studies of the thermo-aerodynamic characteristics of 19 groups from a limited number (4-6) of PFTsm or TP sm heat transfer surfaces and one of 5 tested smooth channeled HTS ( L / d = 19,43 - PFTsm and L / d = 10,50-15,62 - TP sm ) confirmed the realization of rational enhancement of convective heat transfer ( RECHT ) processes and the high level of their estimates (Nu/Nusm)¢max for the value of the complex (Nu/Nusm)Re=idem/(ζ/ζsm)Re=idem = 1, showed the contribution of changed values of geometric parameters δ/ d (0,0580-0,1138), l / d (0,65-3,24) of PFTint and d */ d (0,748-0,953), l / d (0,183-2,003) of TP int HTS in the value of RECHT estimates. There has been proposed and realized (for the studied HTS groups) a technique for determining the ranges of changing values of geometric and regime parameters that proves the realization of the RECHT process, which simplifies the search for rational solutions in the design of heat exchangers. Special conditions of the preparation for the experiments made it possible to exclude the negative effect of side factors on the results.

Presence of uradenia in male adults of the genus Dismegistus (Hemiptera: Heteroptera: Parastrachiidae)
Authors: Pluot-Sigwalt Dominique , Lis Jerzy A.
Published: November 2018

Uradenia, often referred to as paragenital glands, are usually voluminous paired exocrine glands located ventrally in the abdomen mostly on the intersegmental membrane between abdominal segments (= urites) VII-VIII or VIII-IX, depending on sex or the taxon. They have been previously recorded from eight pentatomomorphan families belonging to Coreoidea, Lygaeoidea and Pyrrhocoroidea (Hemiptera: Heteroptera), found either in males, females or both sexes, and were thought to be absent in Pentatomoidea. We report here the first instance of uradenia in a pentatomoid genus, the African Dismegistus Amyot & Serville, 1843 (Parastrachiidae). Only the male adult possesses uradenia located on the intersegmental membrane of segments VIII-IX. The only other genus of the family, Parastrachia Distant, 1883, as well as other examined genera belonging to pentatomoid families possibly related to Parastrachiidae (Cydnidae, Thyreocoridae), do not possess uradenia. The uradenia of Dismegistus exhibit the same fundamental structure as in other trichophoran families but differ by their dorso-lateral position (instead of ventral), and also by the paired orifices (instead of unpaired and median). The implications of the presence of uradenia within member of a pentatomoid genus are briefly discussed.

Published: November 2018

The parameters determining the agronomic and economic performance of genetically modified maize hybrid MON 89034 × NK603 and conventional hybrids were compared under conditions that eliminated the herbicide tolerance in GM hybrid as well as the use of insecticides in conventional hybrids. The GM hybrid confirmed ability to protect itself against the European corn borer and its average grain yield was higher by 6.36-14.42% (i.e. 0.82-1.86 t/ha) in comparison with conventional hybrids. The year of cultivation statistically significant influenced agronomic parameters and the financial income of maize production. The maize genotype did not statistically significantly affected any evaluated parameter. The final income was statistically significant (P < 0.05) negatively influenced by all observed agronomic parameters with the exception of the seed price. The price of maize grains on the market was the only one factor that statistically significant (P < 0.05) influenced financial income of the maize production.

Published: November 2018

A two-year pot experiment (5 kg of soil - Mitscherlich pots) was established in a vegetation hall in Brno (Czech Republic) in the years 2016‒2017. Spring barley, variety KWS Irina, was grown. Chernozem from Brno (with a good magnesium (Mg) content and alkali soil reaction - 7.37) was used for this experiment. The rates of Mg (0.075-0.15-0.3 g per pot) and sulphur (S) (0.1-0.2-0.4 g per pot) were increased by using the ESTA Kieserite fertiliser (25% MgO; 20% S), treatments 2-4. Nitrogen was applied in the form of Calcium Ammonium Nitrate - CAN (27% N) at a rate of 1 g N per pot in all the treatments including the control. The effect of the year was found to be significant on all the parameters under study, with the exception of the soil reaction. The exchangeable soil reaction (pH) after the harvest did not differ in all the fertilised treatments (7.40-7.50) compared to the unfertilised control treatment (7.40-7.45) in both years. The content of post-harvest soil Mg and S increased significantly with the applied rate (285-354 mg Mg/kg in fertilised treatments compared to 276-284 mg Mg/kg in unfertilised control and 47-112 mg S/kg in fertilised treatments compared to 24-54 mg S/kg in unfertilised control, respectively). Dry matter yields of the aboveground biomass were significantly the lowest in the control treatment not fertilised with Mg and S during both years (23.00 and 29.02 g DM per pot) and increased after applications of Mg and S: 27.75-29.25-28.25 in 2016 and 30.33-31.00-34.50 in 2017 (g DM per pot).

Published: November 2018

Changes in the activity of Na+/K+-ATPase, lactate dehydrogenase, and succinate dehydrogenase in the white muscles and gill petals of roach, Rutilus rutilus (L), were studied for the combined actions of water mineralization and water temperature. It was established that decreased mineralization to 260.0 mg dm-3 and increased water temperature to 32°C increased aerobic processes in roach tissues. A sharp increase in water temperature and changes in water mineralization significantly affected the tolerance and physiological state of fish and could impact their abundance in waterbodies.

Published: November 2018

The first aim of the study was to determine the impact the commercial product S.presso (INVE Aquaculture, Belgium) had on enriching the proximate composition of brine shrimp (Artemia sp.). The second aim of the study was to develop a better enrichment protocol for preparing enriched brine shrimp larvae. Two different enrichment protocols were investigated; the supplement was administered in either one (0.5 g L-1) or two equal (0.25 g L-1) doses. Using S.presso to enrich brine shrimp nauplii with polyunsaturated fatty acids resulted in higher levels of total lipids and higher quantities of docosahexaenoic acid DHA and eicosapentaenoic acid EPA deposition. Additionally, the enrichment supplement did not lead to overall lowered protein content values caused by increased hydrolytic activity that likely facilitates digestion in larval fish as they shift to exogenous feeding.
A revised moment error expression for the AIRGA algorithm
Authors: Faßbender Heike , Mayer Julius
Published: November 2018

The fully adaptive rational global Arnoldi method (AIRGA) for the modelorder reduction of second-order multi-input multi-output systems with proportional damping is revisited. The method automatically generates a reduced system approximating the transfer function. It is based on a moment-matching approach. The expansion points are determined iteratively. The reduced order and the number of moments matched per expansion point are determined adaptively using a heuristic based on an error estimation. A revised moment error expression is presented as well as some related findings.
DC-Programming versus ℓ0-Superiorization for Discrete Tomography
Authors: Gibali Aviv , Petra Stefania
Published: November 2018

In this paper we focus on the reconstruction of sparse solutions to underdetermined systems of linear equations with variable bounds. The problem is motivated by sparse and gradient-sparse reconstruction in binary and discrete tomography from limited data. To address the ℓ0-minimization problem we consider two approaches: DC-programming and ℓ0-superiorization. We show that ℓ0-minimization over bounded polyhedra can be equivalently formulated as a DC program. Unfortunately, standard DC algorithms based on convex programming often get trapped in local minima. On the other hand, ℓ0-superiorization yields comparable results at significantly lower costs.

Published: November 2018

The unsteady mass transfer of the packaging constituents to a food has been analysed. The diffusion coefficient inside the packaging was considered concentration - variable while the food was considered concentration spatially gradientless. A well-known technique (Kirchhoff transformation) was used to solve the non-linear mass balance equation. The influence of the non-linear diffusion on the mass transfer mechanism and rate was analysed for different values of the partition coefficient and dilution coefficient.
Riemann Problem for Shallow Water Equation with Vegetation
Authors: Ion Stelian , Marinescu Dorin , Cruceanu Stefan-Gicu
Published: November 2018

We investigate the existence of the solution of the Riemann Problem for a simplified water ow model on a vegetated surface - system of shallow water type equations. It is known that the system with discontinuous topography is non-conservative even if the porosity is absent. A system with continuous topography and discontinuous porosity is also non-conservative. In order to define Riemann solution for such systems, it is necessary to introduce a family of paths that connects the states defining the Riemann Problem. We focus our attention towards choosing such a family based on physical arguments. We provide the structure of the solution for such Riemann Problems.
Error Analysis and Model Adaptivity for Flows in Gas Networks
Authors: Stolwijk Jeroen J. , Mehrmann Volker
Published: November 2018

In the simulation and optimization of natural gas flow in a pipeline network, a hierarchy of models is used that employs different formulations of the Euler equations. While the optimization is performed on piecewise linear models, the flow simulation is based on the one to three dimensional Euler equations including the temperature distributions. To decide which model class in the hierarchy is adequate to achieve a desired accuracy, this paper presents an error and perturbation analysis for a two level model hierarchy including the isothermal Euler equations in semilinear form and the stationary Euler equations in purely algebraic form. The focus of the work is on the effect of data uncertainty, discretization, and rounding errors in the numerical simulation of these models and their interaction. Two simple discretization schemes for the semilinear model are compared with respect to their conditioning and temporal stepsizes are determined for which a well-conditioned problem is obtained. The results are based on new componentwise relative condition numbers for the solution of nonlinear systems of equations. More- over, the model error between the semilinear and the algebraic model is computed, the maximum pipeline length is determined for which the algebraic model can be used safely, and a condition is derived for which the isothermal model is adequate.
MHD convection ow in a constricted channel
Authors: Tezer-Sezgin M. , Gürbüz Merve
Published: November 2018

We consider the steady, laminar, convection ow in a long channel of 2D rectangular constricted cross-section under the inuence of an applied magnetic field. The Navier-Stokes equations including Lorentz and buoyancy forces are coupled with the temperature equation and are solved by using linear radial basis function (RBF) approximations in terms of the velocity, pressure and the temperature of the fluid. RBFs are used in the approximation of the particular solution which becomes also the approximate solution of the problem. Results are obtained for several values of Grashof number (Gr), Hartmann number (M) and the constriction ratios (CR) to see the effects on the ow and isotherms for fixed values of Reynolds number and Prandtl number. As M increases, the ow is flattened. An increase in Gr increases the magnitude of the ow in the channel. Isolines undergo an inversion at the center of the channel indicating convection dominance due to the strong buoyancy force, but this inversion is retarded with the increase in the strength of the applied magnetic field. When both Hartmann number and constriction ratio are increased, ow is divided into more loops symmetrically with respect to the axes.
On the ability of the Generalized Continuum Transport Model to properly capture dispersion
Authors: Vasilyev Leonid , Radu Florin Adrian
Published: November 2018

The ability of the Generalized Continuum Transport model to describe dispersion is studied through the comparison of the breakthrough curves with an analytical solution of the linear advection-dispersion Equation. First, a velocity distribution due to Taylor dispersion in a capillary tube is related to the dispersion coeficient of the advection-dispersion equation. The same distribution is applied to the Generalized Continuum Transport model, where the dispersive flux term is not included as the term proportional to the concentration gradient. In the second stage the velocity distribution is obtained from the transition probability introduced through the Continuous Time Random Walk approach. The approaches support the idea that the Generalized Continuum Transport model captures velocity variations naturally through the parameter space. The results confirm that a proper selection of the parameter space, including its size, leads to more physical transport description as well as accurate quantification.

Published: November 2018

Objective: The aim of the study was to determine differences in the range of socio-demographic variables, selected clinical variables, temperament and character traits, coping with stress strategies and the level of aggression in alcohol addicts with or without a history of suicide attempt(s).

Methods: The study involved 90 people addicted to alcohol, treated in inpatient alcohol dependence treatment program. In order to collect data on socio - demographic variables and selected clinical variables, a self-made questionnaire was used. The severity of alcohol dependence was verified using the MAST and SADD scales. Characteristics of temperament and character were examined with the TCI questionnaire. The BPAQ and COPE questionnaires were used to examine the level of aggression and styles of coping with stress.

Results:Out of 90 subjects with alcohol dependence syndrom, 20% had attempted suicide in the past. The respondents with a history of suicide attempts were statistically significantly younger, were characterized by a younger age of alcohol drinking initiation and the initiation of regular alcohol drinking, and a greater severity of alcohol dependence in the MAST and SADD scales. A significantly larger percentage of respondents who had attempted suicide inflicted self-injury in the past, used other psychoactive substances as well as hypnotics and sedatives. The subjects with a suicide attempt in the interview obtained statistically significantly higher scores in terms of the level of aggression, harm avoidance and self-directedness, and more often used the style of coping with stress based on avoidance and accepting the situation.

Conclusions: The obtained results correspond with data available in the literature and may provide a foundation for theoretical models explaining the phenomenon of suicidal behavior in alcohol addicts as well as for suicide prevention programs in this group of patients.

Ethnograhpy become one of the major method, its emphasis on understanding the perceptions and culture of  people and organization studied. Through differences between  peoples, cultures, moral believes, religiousness may be described, the description  itself will be based on a single view constructed by the gendered, classed, and  raced  position of  the theorist. Foucoulth argued that discourse-practice construct both  the subject and object they describe. An epistemology is a theory of the nature of knowledge and a way of justifying knowledge claims. Humanism is a part of critical thinking which come from human changing form of dignity, role, the idea of enlighment, and the responsibility of humanity. In the javanese christianity context, Kiai Ibrahim Tunggul Wulung teaches the importance appointed human dignity. He inherits some life lesson which are summarizes in own perspective of Christiany and javanese culture on  Tegalombo comunity. Tunggul Wulung combines the wisdom of javanese culture and christianity in accordance of the condition and the requirement of the society. Those combination concept is manifested through in  mission method theory which aim guide human to life their lives properly. However, this method was not accapted by the foreign missionaries, and in the social structure at that time. They accused Tunggul Wulung’s method as form of sincretism. This work is an attemp to analyze Tunggul Wulung mission method in the context of Indonesia, it is perhaps more to make explicit the lack of a common  methodology, formulate one true to at least one understanding of what “critical” means, and encourage debate, and discussion on the issue. The justification of knowledge claims involves, as in the case of example, stating a position and defending that position with reason. It’s hope that Tunggul Wulung’s achievment can be aprreciated by the present generation, and they will negotiated epistemology in a history classroom which different some point of views.
