One of the devices implementing energy-saving technologies is a Venturi tube of special geometry, called the cavitations generator of fluid pressure oscillation (hereinafter referred to as the generator). It converts the steady-state flow of process fluid into a discrete-impulse flow of increased power and has the simplicity of manufacturing that lacks moving parts, does not require additional energy sources and seamlessly fits into existing equipment. The practical use of the generator in engineering, metallurgy, the chemical industry and in mining, can reduce the specific energy consumption by up to 50%. The purpose of this paper is a comparative analysis of the existing methods for calculating the amplitudes of pressure oscillations generated by the generator and the choice of a method that makes it possible to determine the amplitudes with an acceptable accuracy. The technique is based on the determination by various computation methods of peak-to-peak values of the fluid pressure from the cavitations flow regime. The results are presented in the form of calculated dependences of the of peak-to-peak oscillation values of the fluid pressure on the value of the cavitations parameter and their comparison with the experimental data. Scientific novelty. It is established that the method using the finite-element discretization of the generator and outlet pipeline construction with fluid moving in it satisfactorily describes the parameters of the oscillatory process in various elements of the hydraulic system. However, the model requires some correction in the part of the description of the basic dependencies describing the dynamics of the cavitations flow in the generator, if it is necessary to more agreement with the experimental data. This model is convenient for carrying out multi-purpose research works, including experimental data correction, but its application for engineering calculations causes certain difficulties in the part of programming and the length of preparation for the calculations. The refined linear mathematical model of the generator makes it possible to obtain a quantitative agreement between the experimental and theoretical dependences of the amplitude of fluid pressure oscillations on the cavitations parameter by engineering methods. The practical significance of the results obtained is that the refined linear mathematical model of the generator makes it possible to establish at the design stage a rational regime of the hydroimpulse action of the generator (the peak-to-peakvalues of fluid pressure oscillations) at a certain pressure in the process pipeline of an industrial plant and does not require additional experimental studies

Authors: Abad Andrés , Naranjo Efraín , Ramos Valentina
Published: May 2019

En este artículo se elabora una propuesta conceptual y práctica para el diagnóstico de la cultura organizacional fandamentada en el método etnográfico, sobre la base de las consideraciones teóricas elaboradas por Hatch (1993) y Schein (1996), cuyas premisas se sustentan en aspectos simbólicos e interpretativos de lo social. El estudio empírico se realizó en una institución bancaria de carácter mediano en Ecuador, para lo cual las autoridades decisoras manifestaron la voluntad de un cambio en el modelo de gestión de la misma. Para el procedimiento de recogida, categorización e interpretación de los datos se utilizó el método etnográfico. Las correlaciones entre las categorías y subcategorías se realizaron a partir del coeficiente de correlación de Pearson. Nuestros resultados indican el estudio de la cultura organizacional a partir de su deconstrucción en cuatro categorías fundamentales, que se relacionan entre sí: artefactos, símbolos claves, valores y  presunciones. Esto demuestra la complejidad en el estudio de la cultura en las organizaciones, a la vez que valoriza el uso de la etnografia organizacional enfocada como método para la comprensión de la misma a nivel de simbolismos y construcciones compartidas.

Perbedaan Status Anemia Gizi Besi Remaja Putri yang Bersekolah di SMA Program dan Non-Program Suplementasi Tablet Tambah Darah
Authors: Rahmadi Antun
Published: May 2019

The results of Riskesdas in 2013 showed that the incidence of anemia in young women was still high at 22.7%. One of the efforts made by the Indonesian government in overcoming the problem of anemia in young women is by distributing iron supplementation tablets (TTD) to school girls. The TTD supplementation program for young women currently does not cover all educational institutions at the junior or senior high school level. This raises the question of whether there are differences in anemia status between schools that have implemented TTD supplementation programs and schools that have not implemented them. The general purpose of this study was to determine the anemia status of iron nutrition in high school students. The specific objectives of the study were to 1) assess the state of anemia in high school students with TTD supplementation program, 2) determine the status of anemia in high school students with non-TTD supplementation program and 3) find out the difference in the state of anemia between both high school students. The sample of this study was taken randomly from two schools in Bandar Lampung, namely SMK 1 as many as 75 people and Al-Azhar High School as many as 72 people. Data processing is carried out with the computer, and a different test is carried out by testing the kai quadratic statistics. The results showed that the incidence of anemia at SMK 1 was 24.0% while at Al-Azhar High School was 43.1%. There was a significant difference between the prevalence of anemia at SMK 1 Al-Azhar High School with a value of p = 0.023. The Health Service is expected to expand the coverage of the TTD program to schools that have not been covered by the TTD supplementation program. The school can participate in providing self-help TTD.

Endovascular catheter knot untying: A new technique
Authors: Soule Erik
Published: May 2019

Indwelling vascular catheters may be maintained for extended periods of time especially for critically ill or hospitalized patients requiring frequent blood draws. If they become knotted within the vasculature, serious iatrogenic sequelae can result, such as: pneumothorax, atrial arrhythmias, ventricular arrhythmias, pulmonary embolism, pulmonary hemorrhage, intracardiac rupture, pulmonary artery rupture, balloon rupture, bacteremia, and death. Surgical cut-down may be indicated for removal of knots that preclude catheter retrieval and are refractory to intravascular removal modalities. Three such knots were untied using the intraluminal technique described in this report. The technique utilizes balloon angioplasty in conjunction with a wire to safely and effectively untie knotted catheters. Keywords: Vascular catheters, Arrhythmias, Angioplasty balloon.

Authors: Hristich T. N. , Hontsariuk D. O.
Published: May 2019

In this article, the authors analyze a number of known and probable mechanisms involved in the formation of metabolic disorders upon chronic pancreatitis in comorbidity with metabolic syndrome. The issue of involvement of pancreatic endocrine apparatus in development of insulin resistance upon chronic pancreatitis, namely, the role of such a hormone as insulin, is highlighted. The role of this hormone in development of disorders of fat metabolism, obesity and arterial hypertension is presented. The authors emphasize the role of adrenal hormones, estrogen in the pathogenesis of both diseases. The issue of effect of endocrine function disorders on the state of external pancreatic secretion with subsequent development of disorders in the microbiota composition is considered (which also contributes to the progression of both diseases).

The data on presence of a possible relationship between the composition, functional activity of the intestinal microbiota and development of metabolic syndrome, chronic pancreatitis are given. The significance of intestinal microbiota in the maintenance of various vital processes of a healthy person, food digestion, as well as synthesis, metabolism, recycling, utilization of various biologically active substances (vitamins, hormones, steroids, immunoglobulins) and elimination of toxins is revealed. The role of microorganisms in the formation of feeding behavior via axis “intestinal microbiome — intestine — brain” is analyzed. Modern ideas on the ability of microorganisms to provoke formation of metabolic disorders upon chronic pancreatitis are presented. The data confirming connection of certain dysbiotic changes (increased ratio of Firmicutes/Bacteroidetes, reduced number of Bacteroidetes and increased number of Firmicutes) with development of obesity, overweight, type 2 diabetes mellitus (known risk factors of metabolic syndrome) is given. It is suggested to prevent formation of metabolic syndrome in chronic pancreatitis by increasing the number of specimens of Bifidobacterium genus and Faecalibacteriumprausnitzii strains in the intestine.

Numerical simulation on hydrodynamic performance of parallel twin vertical axis tidal current turbines
Authors: Sun Ke , Xuehan Zhou , Yan Li , Liang Zhang
Published: May 2019

Single and parallel twin vertical axis hydro turbines were numerically simulated by using OpenFOAM software, studying the interference effects, such as torque and load of turbine, as well as hydrodynamic performance influenced by the distance and rotation forms between twin turbines, and analyzing the wake flow field to show the velocity profile distribution. The results showed that the average power of parallel twin turbines is always higher than the power of a single turbine, and the closer the lateral distance between turbines, the higher the power. When lateral distance approximates to 1.25 times turbine diameter, and turbines rotate in the opposite inward direction, the average energy efficiency value of parallel twin turbines is about 25 % higher than that of a single one. Additionally, opposite inward rotation is the best arrangement form for twin turbines to obtain more power and counteract lateral force.

Ontogenetic Development of Sensitivity of the Cerebral Cortex to an Antagonist of GABAA Receptor Bicuculline
Authors: MAREŠ P. , BERNÁŠKOVÁ K. , KUBOVÁ H.
Published: May 2019

Local application of four concentrations of bicuculline methiodide (a specific antagonist of GABAA receptors) was used to study a sensitivity of somatosensory cortex in four age groups of immature rats with implanted electrodes. Presence and latencies of two epileptic phenomena (focal discharges and seizures) were evaluated. Focal discharges exhibited moderate tendency to a decrease of sensitivity to bicuculline methiodide with maturation. Concentration-effect relation of incidence of focal discharges was observed only in 7- and 12-day-old but not in older animals. Results with incidence and latencies of seizures did not show relations to age or concentration of bicuculline. Neither of the epileptic phenomena can be used as a reliable index of cortical maturation.
The Role of Endogenous Reactive Oxygen Species in Cardiac Myocyte Autophagy
Authors: WANG Jia-Pu , CHI Rui-Fang , LIU Jia , DENG Yong-Zhi , HAN Xue-Bin , QIN Fu-Zhong , LI Bao
Published: May 2019

Autophagy is implicated in the maintenance of cardiac homeostasis. Autophagy is activated in heart failure, in which reactive oxygen species (ROS) are increased. Exogenous ROS have been shown to induce cardiomyocyte autophagy alterations. However, little is known about the influences of physiological levels of endogenous ROS on cardiomyocyte autophagy. In the present study, we tested the hypothesis that endogenous ROS in cardiomyocytes play an important role in inducing autophagy. Cultured H9C2 cardiomyocytes or Sprague-Dawley rats were treated with the antioxidant N-acetyl-cysteine (NAC) or the superoxide dismutase mimic tempol under the basal or nutrient deprivation conditions. The autophagic flux was assessed by the lysosomal inhibitor chloroquine. In H9C2 cardiomyocytes, under a basal condition, NAC or tempol increased the ratio of LC3 II/I proteins and reduced LC3 II autophagic flux. Under nutrient deprivation, NAC increased the LC3 II/I ratio and reduced LC3 II autophagic flux. In vivo studies in rats, NAC treatment increased the LC3 II/I ratio and p-Akt protein expression in myocardium. We concluded that the antioxidants reduced autophagic flux in cardiomyocytes under the basal or nutrient deprivation conditions, suggesting that endogenous ROS promote autophagy flux under physiological conditions, and this effect is mediated, at least in part, through Akt inhibition.

Published: May 2019

The law of registration of company charges is of considerable importance for corporate finance transactions throughout the UK. This article analyses the current regime that came into force on 6 April 2013. It examines various aspects of the regime, principally from a Scots law perspective, including what is meant by a “charge”, when charges are created, the extent to which unregistered charges are effective, and the rules regarding registration of charges over acquired property. The article demonstrates that, although the new regime is a general improvement on the previous one, there are a number of new and familiar problems concerning its applicability and operation in relation to Scots law. There are also some implications involving the uniformity of Scots law and English law in the area that arise from the fact that the regime is now UK-wide.

SD Negeri Purworejo is a primary school with adequate learning facility, such as computer laboratories, projectors, and internet connection. Although teachers, students, and parents have the access and the skills to use information technology, the school facility has not been optimally used. It is assumed that the application of such skills and the use of school facility will improve the learning process and the students’ learning outcomes. In this case, information technology is used to combine a face-to-face learning process and an online learning process, which is known as “blended learning”. The twenty-four teachers of SD Negeri Purworejo did not have prior experience with the blended learning process, although they have the potential to apply it in their class. The solution for this is to hold a workshop on Blended Learning. The materials of the workshop should include blended learning planning, blended learning practical implementation, and information on the supporting materials required in blended learning. The methods used in the workshop are lecture, practicum, and simulation. The outcomes are offline and online lesson plans.
