Effect of recuperative volume parameters on dynamic characteristics of pneumatic drive underbraking
Authors: Sirotenko A. N. , Partko S. A. , Salloum Wael 
Published: January 2019

Introduction. Methods of energy saving in pneumatic drive are considered. The method of braking by creating back pressure in the exhaust cavity of the pneumatic actuator is of interest. Under braking, the compressed air energy is stored in the recuperative volume. It is possible to control the braking dynamics through setting the initial parameters of the recuperative volume. The work objective is to create a mathematical model describing the dynamic processes taking place in the pneumatic drive under braking by backpressure, with a constant mass enclosed in the cavities of the air motor, and considering variation of the initial parameters of the braking volume.Materials and Methods. A mathematical model is proposed that describes the speed change of the output link, pressures and temperatures in the cavities of the pneumatic drive depending on the initial parameters of the recuperative volume. The solution to the mathematical model is carried out by the numerical integration method.Research Results. The dependences of the output link velocity, pressures and temperatures in the pneumatic drive cavities on the initial parameters of the recuperative volume are obtained. Adequacy of the built mathematical model is confirmed by Fisher's criterion.Discussions and Conclusions. The results obtained can be used to solve the problems of energy saving in pneumatic drives under the organization of backpressure braking. The use of recuperative volume increases the technological flexibility of the drive during its readjustment and extends the possibilities of energy saving.

Authors: Shcherbakov V. N. 
Published: January 2019

Introduction. The work objective is to increase the reliability of the prediction methods for the lithium hydroxide behavior in the steam-water circuit at the thermal power plants and nuclear power plants, and for the operational monitoring of the pH index of steam solutions. A method of operational control is developed on the basis of the conductometric measurements of the hydrogen index of the corrosion inhibitor vapor solutions for construction materials of lithium hydroxide used at the TPP and NPS.Materials and Methods. A mathematical model method is used for the practical implementation of the high-temperature operational control of the steam solution pH index.Research Results. A method for monitoring the pH of vapor solutions of lithium hydroxide based on the determination of vapor concentration through the steam condensation in the coolable conductivity sensor located in the vapor space of the steam generator is developed. This has significantly improved the accuracy of determining the lithium hydroxide concentration. Equations describing the change in the limiting molar equivalent conductance and dissociation constants of lithium hydroxide in a wide range of state change parameters are proposed.Discussion and Conclusions. The proposed on-line technique of testing the pH value of steam solutions, and mathematical models for calculating the limiting molar equivalent conductance and dissociation constants provide an acceptable error level calculations and the capability of measurements automation. With an increase in the vapor temperature up to 573.15 K, the necessity arises to fortify lithium hydroxide in the vapor to 10-2 mol/kg.
Estimation of proximity of controls synthesized on basis of maximum principle and ADAR method

Published: January 2019

Introduction. A special case of synthesizing the same electromechanical control system by the Pontryagin maximum principle and by the synergetic synthesis method is considered. The task was to solve the synthesis problem of the time optimal electromechanical position control system; herewith the travel resistance modulus linearly depended on the output coordinate of the system. This approach to the selection of the synthesis problem was because the synthesis of time optimal systems is one of the most widespread problems, and it is solved by increasing the efficiency of the existing control systems.Materials and Methods. Synthesis of the time optimal linear control system based on the maximum principle is a widely accepted problem in the modern control theory. However, the procedure of synergistic synthesis does not have such formalization. This being the case, the paper suggests an approach that brings together these two methods, which, in our opinion, will increase the efficiency of the synergistic synthesis method through adding some features of the synthesis methodology for optimal systems.Research Results. The paper formulates two key concepts. The first one is as follows: the application of the maximum principle for an object of the DC motor class when synthesizing the positioning algorithm under the conditions of linear loading functionally dependent on the engine rotation angle allows the time optimal system to be optimized. The second concept states that synthesis of a control system based on the synergistic approach enables to obtain a system close to optimal (quasioptimal), but after modifying the synergetic synthesis method itself. A hypothesis is formulated on the possible connection between the introduced (when implementing the procedure of state space extension in the synergetic synthesis method) time constants with the optimal switching time of control defined in the maximum method.Discussion and Conclusions. The synthesis through the maximum control technique and the ADAR method is performed. In virtue of the comparison of efficiency of these methods, a hypothesis is put forward on the possible compatibility of the studied methods.
Menggagas Hak Kekayaan Intelektual Perspektif Hukum Islam ke dalam Hukum Nasional
Authors: Triana Nita 
Published: January 2019

This study aims to describe and analyze Intellectual Property Rights (IPR) under the rules of Trade-Related Aspects of Intellectual Property Rights (TRIPs) which are in several respects different from the laws that live in Indonesia. Therefore, it is necessary to initiate Intellectual Property Rights Law that is in accordance with the values that live in Indonesia, the majority of which are Muslim communities. The results of this study illustrate that the legal protection of the owners of InÂ­tellectual Property Rights (IPR) in Indonesia has been regulated in various laws and regulations that are included in the Intellectual Property Rights Law system. These regulations must refer strictly to the TRIPs Agreement. The Intellectual Property Rights regime with the rules of TRIPs has two sides in the protection of intellectual property rights, on the one hand it protects individual interests from piracy and theft of intellectual property, but on the other hand empirically this leÂ­gal protection greatly benefits developed countries. Based on this, the Intellectual Property Rights Law must be rebuilt with the source of material law originating from values that live in Indonesian society, namely Islamic law.

Authors: Kadri Muhammad 
Published: January 2019

Air tanah adalah air yang terdapat dalam suatu lapisan tertentu di dalam tanah yang berada dalam ruang antar butiran batuan ataupun rekahan batuan. Air tanah merupakan alternatif air yang dapat digunakan dalam berbagai kebutuhan. Di daerah Tanjung Balai, air tanah sangat sulit diperoleh, khususnya kecamatan Teluk Nibung. Penelitian ini dilakukan untuk untuk mendapatkan alternatif sumber air yang lain yaitu sumber air tanah guna memenuhi kebutuhan air bersih dan layak minum bagi penduduk setempat untuk saat ini dan masa yang akan datang di Kecamatan Teluk Nibung. Metode yang digunakan adalah metode geolistrik resistivitas dengan konfigurasi Wenner-Schlumberger dengan mengambil 3 lintasan. Lintasan I dan II sebanyak 32 elektroda dengan panjang lintasan 155 meter. Lintasan ketiga sebanyak 16 elektroda dengan panjang lintasan 75 meter. Data yang diperoleh diolah dengan menggunakan software Res2DinV. Hasil penelitian menunjukkan bahwa dari ketiga lintasan yang berbeda di Kecamatan Teluk Nibung memiliki resistivitas yang bervariasi yaitu sekitar 0,199 Ωm sampai dengan 48,8 Ωm pada lintasan pertama dan 0,085 Ωm sampai dengan 12,1 Ωm pada lintasan kedua serta pada lintasan ketiga yaitu sekitar 0,5 Ωm sampai dengan 138 Ωm. Potensi air tanah di daerah yang diteliti pada lintasan pertama dan kedua masih kecil dan diduga air tanah berada pada akuifer tertekan karena di sekitarnya dilapisi oleh lapisan kedap air seperti lempung / tanah liat. Sedangkan pada lintasan ketiga potensi air tanah cukup besar dan berada pada akuifer bebas. Sumber air tanah pada lintasan ketiga dapat dimanfaatkan oleh masyarakat untuk memenuhi kebutuhan sehari-hari karena potensinya lebih besar dari pada lintasan pertama dan lintasan kedua dan berada pada akuifer bebas sehingga mudah untuk dibor.Kata kunci : Air Tanah, Akuifer, Geolistrik
New species of osmundaceous fertile leaves from the upper Triassic of Argentina
Authors: Coturel Eliana P. , Bodnar Josefina , Morel Eduardo M. , Ganuza Daniel G. , Sagasti Ana J. , Beltrán Marisol 
Published: January 2019

AbstractA new species of Osmundopsis Harris is described based on several impression-compression fossils from the upper section of the Potrerillos Formation (Uspallata Group) at Cerro Cacheuta Hill, Mendoza Province, Argentina. Osmundopsis zunigai sp. nov. is characterized by having fertile pinnae with a slender striate rachis, bearing widely separate, opposite to subopposite short falcate pinnules with an entire margin, rounded apex, and a partially reduced lamina. The pinnules bear sporangia loosely disposed in clusters of four or five on the abaxial side. The sporangia are wedge- to heart-shaped, shortly stalked, with cells of the apical region thickened, and have a vertical dehiscence slit. The spores are trilete and laevigate. This is the first record of Osmundopsis in the Triassic of Argentina. The mutual occurrence or co-preservation of Osmundopsis zunigai sp. nov. with sterile fronds of Cladophlebis kurtzi suggests the possibility that these species formed part of a dimorphic bipinnate frond. The diversity and geographic extent of fertile leaves of the Osmunda lineage in the early Late Triassic, with records in South Africa and Antarctica and now with this new taxon, support the idea of a moist mesothermal climatic belt in southern Gondwana.

Abstract
In the present study we tested the dose andh time dependence of the antinematodal effects of carvacrol and tyhmol on Caenorabditis elegans, and the efficacy of carvacrol, thymol, p-cymene and cinnamaldehyde,which were administrated in the drinking water of rats naturally infected with the pinworm Syphacia muris. The control treatment of the infected rats was carried out with piperazine. Thymol caused a dose and time-dependent mortality in adult C. elegans. The value of the Median Lethal Concentration (LC50) of thymol was 117.9nM after 24h and 62.89 nM after 48h of exposure. Carvacrol exhibited a higher antinematodal efficiency than thymol. The LC50 of carvacrol, after 24 hours of exposure, was 53.03 nM, while after 48 hours it was 33.83 nM. On the other hand, piperazine showed an extremely high efficacy against S. muris infection in rats. Piperazine, at a dose of 625 mg/kg bw, administered in drinking water continuously for 10 days, eliminates the infection completely. However, none of the investigated active ingredients of essential oils were effective against S. muris. The reason for the lack of efficiency may be due to their pharmacokinetic properties. A relatively low amount of, orally administered, active ingredients of essential oils reaches the distal segments of the gastrointestinal tract, where S. muris inhabits the gut (colon and cecum). The obtained results, on C. elegans, indicate a clear dose and time-dependent antinematodal effect of thymol and carvacrol. However, for clinical application, it is necessary to examine the efficacy of microencapsulated formulations with a controlled release of active ingredients of essential oils in certain parts of the gastrointestinal tract.

Published: January 2019

Abstract
A comparative study of the phenolic complex, the resveratrol content, the antioxidant activity and the organoleptic profile of Bulgarian wines from the local vine varieties Dimyat, Pamid, Gamza and from the hybrid varieties Plevenska rosa, Storgozia, Kaylashki rubin was carried out. Differences in the chemical composition and tasting characteristics of the experimental wines were identified. As for the white wines, Dimyat had higher sugar-free extract and titratable acidity, while concerning the red ones, Storgozia and Kaylashki rubin showed higher rates. The trans-resveratrol amount in the red wines was significantly higher compared to the white ones, as the samples from the red local varieties had a higher content than the hybrid varieties. Difference in the phenolic composition of the wines was also found. Gamza wine had the highest concentration of total phenolic compounds, total flavonoids and catechin. Storgozia sample contained the highest rates of monomeric anthocyanins and epicatechin. Pamid revealed the lowest concentrations of all analyzed phenolic components except catechin. The red wines had better antioxidant features than the white ones. From the red wines, the highest and the lowest activity were reported in the local varieties – Gamza and Pamid, respectively. There was no strict correlation between the effects of the studied phenolic components on the wine organoleptic profile.

Published: January 2019

Abstract

Objective: The objective of this study was to analyze the performance of 2 stimulation tests used in the diagnosis of growth hormone deficiency.

Method: A retrospective study was conducted on a non-random sample of 310 patients, between 2 and 20 years old, who were hospitalized in the Mureș County Hospital’s Endocrinology Department and in the National Institute of Endocrinology C.I. Parhon with short stature between 2009-2015. Inclusion criteria: all subjects who underwent growth hormone stimulation tests in accordance with the national protocol. Microsoft Office Excel was used for data collection and MedCalc v 12.5 was used for statistical analysis.

Results: From the total of 310 patients, 102 were diagnosed in Târgu Mureș and 208 in Bucharest. Sex ratio favored boys (boys:girls 1.64:1). In 173 subjects growth hormone deficiency was confirmed. For both tests the percentage of maximum response was the highest for the 60 minutes blood sample regardless if the test were positive or not. Both tests have 100% sensitivity and negative predictive value, with the highest specificity for the 60 minutes clonidine and 30 minutes insulin. The false positive rate was 60% for the insulin test and 27.2% for clonidine for Târgu Mureș sample and 86.9% for the insulin test and 62.5% for clonidine for Bucharest sample. The concordance of the 2 tests was 49.36%.

Conclusions: Stimulating growth hormone testing has a number of limitations but is still needed in some auxological circumstances. We recommend performing the clonidine test first to exclude idiopathic short stature and then the insulin tolerance test for the diagnosis of growth hormone deficiency.
Brain death as irreversible loss of a human’s moral status
Authors: Nowak Piotr Grzegorz 
Published: January 2019

Abstract
Singer claims that there are two ways of challenging the fact that brain-dead patients, from whom organs are usually retrieved, are in fact biologically alive. By means of the first, the so called dead donor rule may be abandoned, opening the way to lethal organ donation. In the second, it might be posited that terms such as “life” and “death” do not have any primary biological meaning and are applicable to persons instead of organisms. This second possibility permits one to acknowledge that brain-dead patients are deceased because they are irreversibly unconscious. In the commentary which follows, I will argue that Singer’s second option is preferable since it (a) provides a higher amount of organs available for transplant, and (b) is better suited to the meaning of “death” which occurs in ordinary language. I will also defend such a concept of death against the objections raised by Michael Nair-Collins in the article Can the brain-dead be harmed or wronged? On the moral status of brain death and its implications for organ transplantation.
