Polycystic Ovary Syndrome as a systemic disease with multiple molecular pathways: a narrative review
Authors: Carvalho Laura M. L. , dos Reis Fernando M. , Candido Ana Lucia , Nunes Fernanda F. C. , Ferreira Claudia N. , Gomes Karina B.
Published: November 2018

Polycystic Ovary Syndrome (PCOS) is characterized by hyperandrogenism, amenorrhea, and polycystic ovaries. This endocrinopathy is associated with many metabolic disorders such as dyslipidemia and insulin resistance, with increased risk of type 2 diabetes mellitus, metabolic syndrome, and cardiovascular complications. Inflammation is likely to play an important role in the promoting these metabolic imbalances, while prothrombotic and pro-oxidative mechanisms further contribute to the cardiovascular risk of these patients. The etiology of PCOS is still not fully understood, but there is evidence of genetic and environmental components. This review aims to discuss some molecular pathways associated with PCOS that could contribute to the better understanding about this syndrome. Recent evidence suggests that intrauterine exposure of female mice to an excess of anti-Müllerian hormone may induce PCOS features in their post-natal life. High cytokine levels and cytokine gene polymorphisms also appear to be associated with the pathophysiology of PCOS. Furthermore, high levels of microparticles may contribute to the altered hemostasis and enhanced inflammation in PCOS. All these mechanisms may be relevant to clarify some aspects of PCOS pathogenesis and inspire new strategies to prevent the syndrome as well as treat its symptoms and mitigate the risk of long-term complications.
Double-Diffusive Convection of Synovial (Couple-Stress) Fluid in the Presence of Hall Current Through a Porous Medium
Authors: Singh M.
Published: November 2018

An investigation made on the effect of Hall currents on double-diffusive convection of a compressible synovial (couple-stress) fluid in the presence of a horizontal magnetic field through a porous layer is considered. The analysis is carried out within the framework of linear stability theory and normal mode technique. A dispersion relation governing the effects of viscoelasticity, compressibility, magnetic field and porous layer is derived. For the stationary convection, a synovial fluid behaves like an ordinary Newtonian fluid due to the vanishing of the viscoelastic parameter. The stable-solute gradient, compressibility, and magnetic field have postponed the onset of convection, whereas Hall currents and medium permeability have not postponed the onset of convection, moreover, a synovial fluid has a dual character in the presence of Hall currents, whereas in the absence of Hall current in synovial fluid have postponed the onset of convection, which is in contrast in case of thermal convection couple-stress fluid with same effects. These analytic results are confirmed numerically and the effects of various parameters are depicted graphically. It has been observed that oscillatory modes are introduced due to the presence of viscoelasticity, magnetic field, porous medium and Hall currents which were non- existent in their absence. The sufficient conditions for the non-existence of overstability are also obtained.
Boundary Layer Analysis in Nanofluid Flow Past a Permeable Moving Wedge in Presence of Magnetic Field by Using Falkner – Skan Model
Authors: Ali M. , Alim M.A.
Published: November 2018

In the present work, the effect of various dimensionless parameters on the momentum, thermal and concentration boundary layer are analyzed. In this respect we have considered the MHD boundary layer flow of heat and transfer over a porous wedge surface in a nanofluid. The governing partial differential equations are converted into ordinary differential equations by using the similarity transformation. These ordinary differential equations are numerically solved using fourth order Runge–Kutta method along with shooting technique. The present results have been shown in a graphical and also in tabular form. The results indicate that the momentum boundary layer thickness reduces with increasing values of the pressure gradient parameter β for different situations and also for the magnetic parameter M but increases for the velocity ratio parameter λ and permeability parameter K*. The heat transfer rate increases for the pressure gradient parameter β, velocity ratio parameter λ, Brownian motion parameter Nb and Prandtl number Pr but opposite result is found for the increasing values of the thermoporesis parameter Nt. The nanoparticle concentration rate increases with an increase in the pressure gradient parameter β, velocity ratio parameter λ, Brownian motion parameter Nb and Lewis number Le, but decreases for the thermoporesis parameter Nt. Finally, the numerical results has compared with previously published studies and found to be in good agreement. So the validity of our results is ensured.
Continuity and Extinction of Agricultural Land in the Sudetes - A Case Study in the Landscape of Highlands and Mountains
Authors: Zelinka Vít
Published: November 2018

The Sudetenland has undergone a dramatic development in Czechia. Above all, the frontier regions of the then Czechoslovakia lost due to the decision on the displacement of the Sudeten Germans in 1945 almost 3 million native inhabitants, who left their settlement areas in several waves by 1947. This change affected up to 3 million hectares of agricultural land that became the state property. This had in many places eliminated the traditional way of farming and the disruption of ownership relations consequently led to the breaking of relations in the landscape. This case study focuses on the comparison of the development of the agricultural landscape of 4 selected cadastral areas on the border of Krkonoše and Jizera Mountains from the post-war period to the present. Selected areas of interest are pairs of comparable cadastres from areas affected by the displacement of the local German population and areas with a permanent population structure. This four sites covering a total area of 4052 ha were studied in Cool Landscape of Highlands and the Moderately Cold Landscape of Mountains. Historical and contemporary land-cover information was provided by aerial photographic images from 1953/1954 and aerial orto-photos from 1998 and 2015/2016. The results have shown that on all four of the areas there was a noticeable increase in forests on former agricultural land. However, the monitored areas differ in the continuity of agricultural land. Continuous agricultural land represents, in both areas affected by post-war displacement, approximately 55 % of the original agricultural land. Areas with a well-preserved population structure, on the other hand, show an overall continuity of agricultural land on about 71 % of the former area of agricultural land.
Performance and Stability Analysis of Series-Cascaded, High-Gain, Interleaved Boost Converter for Photovoltaic Applications
Authors: Kumar C. Prasanna , Venugopal N.
Published: November 2018

Interleaved boost converters (IBCs) are cascaded in parallel in most of the applications. This novel approach connects IBC in series cascade. The IBC has an optimal operating duty cycle of 0.5. Normally, photovoltaic source voltage is low because of space constraints. In order to boost the source voltage, a conventional boost converter is replaced with series-cascaded IBC in this paper. The single-stage IBC also boosts the voltage to twice the input voltage. In the proposed converter, output voltage is about four times the input voltage with the same 0.5 duty cycle. A mathematical model is developed and simulated for the proposed work in MATLAB/Simulink platform. The output of the proposed circuit is analysed through fast Fourier transform to know the harmonic content due to the switching. The system is tested for stability with signal-flow graph modelling. The proposed work is realised using hardware and tested to validate the model.
Perpaduan Nada‐nada dalam Perspektif Harmoni dan Aplikasinya Terhadap Mahasiswa
Authors: Kaestri V. Yoni
Published: November 2018

The combination of tones in the diatonic musical study is called the harmony. Harmony here is intended for the human voice, that encompasses the soprano (S) for high female voice, the alto (A) for low female voice, the tenor (T) for high male voice, and the bass (B) for low male voice. Each sound has a different register, as it was introduced at the beginning part of many harmony text books, for example the one that was written by Gustav Strube. The initial step of tonesarrangements is based on the tonic, dominant, and sub‐dominant chords. Because the triad chord is consists of 3 notes only while the four voices are needed in the SATB arrangement, doubling the one of triad components is necessary. In addition to doubling treatment we should be aware of applying the proper chord positions, whether it is the basic position (bass doubling), the first inversion (soprano doubling), or the second inversion (bass doubling). In the fourth voices chord, eg the dominant seventh chords, although it is possible to treat the doubling by eliminating the element of its tone composite, it is not usually applied due to the number of its chord tones is already four. While in its application to the student, it is better to be based on the memorization of basic chords, for example major, minor, diminished, and augmented chords, after that continued by working on the triad chord, four voice chords, and also the neapolitan sixth.

Published: November 2018

Perubahan fluktuasi frekuensi sangat mempengaruhi kualitas daya pada sumber energi terbarukan turbin angin yang dihibrid dengan diesel. Sistem hibrid adalah jaringan terkontrol dari beberapa pembangkit tenaga energi terbaharukan seperti : turbin angin, sel surya, mikrohidro dan sebagainya. Ada beberapa permasalahan yang dapat meningkatkan osilasi frekuensi rendah, seperti tidak optimalnya setting gain dan kecilnya waktu konstan pada Automatic Voltage Regulator, Terlalu banyak jaringan transmisi yang panjang sehingga kemampuan lemah (weak line). Dalam penerapannya sistem wind-diesel dikontrol dengan kontroler PID, namun dalam penyetelan nilai gain dari PID masih dalam metode trial-error saja, sehingga sulit untuk mendapatkan nilai optimum dari PID. Dalam penelitian ini diterapkan desain kontrol dengan menggunakan Metode Cerdas dalam mencari nilai optimum Proporsional Intergral Derivatif (PID) untuk mengatur frekuensi beban dengan program Matlab/ Simulink. Pemodelan wind-diesel menggunakan fungsi transfer dari diagram turbin angin dan diesel. Respon sistem dengan Simulink/ Matlab dengan membandingkan dengan sistem tak terkontrol dan dengan metode PID-Trial Error, menunjukkan bahwa besar overshoot dan respon keadaan mantap (Settling Time) pada sistem terkontrol Differential Evolution (DEVO) menjadi berkurang dan lebih cepat.AbstractChanges in load frequency greatly affect the power quality of renewable wind turbine energy sources with diesel. Hybrid power system is a network consisting of several renewable energy plants such as wind power, solar power, hydro power, and others. Some problems can increase the low frequency oscillations in the system, such as gain settings and small time constants of the non-optimal Automatic Voltage Regulator, long transmission lines so that their capabilities are weak (weak line). In some previous studies, the wind-diesel system is controlled by conventional Proportional, Integral, Derivative (PID) controllers, but the PID gain setting is still in the trial-error method, making it difficult to obtain optimal PID values. In this research, we proposed a method of optimizing PID parameters in wind-diesel by using intelligent method based on Differential Evolution (DEVO). The objective function of this research is to minimize Time Absolute Error (ITAE), so that the overshoot will be muted properly. Wind-diesel modeling uses the diagram of the transfer function of wind-diesel. From the analysis results obtained optimal PID parameters respectively, Kp = 79.9999, Ki = 59.9998, Kd = 9.9006. The smallest resulting overshoot is -7.932e-05 to 6.792e-10 pu where the smallest overshoot value is compared to other controller models. The frequency response obtained by optimal PID tuning will dampen the frequency oscillation due to load changes, indicated by small overshoot and fast settling time to steady state conditions.

Published: November 2018

The subject of our study was the analysis of information security of the object of a particular credit and financial sphere, issuing microloans. The authors built a plan-scheme of a typical object of the credit and fnancial sector. We also described the organizational structure and staff structure of the microloans organization. Further, we conducted an analysis of the organization’s staff, their activities, and areas in which they have the right to access. On the basis of the obtained data, we constructed a model of threats to information security of the microloans organization. The authors determined the correspondence of the types of threats to the types of violators of information security. We have built a three-dimensional model of information security, which allows us to calculate the vulnerability factor of the object of credit and fnancial sector, based on the data obtained in the company issuing micro-loans, as well as available statistics. The main parameters that determine the security indicators are identifed: the number and characteristics of destabilizing factors that can manifest themselves and have a negative impact on the protected information; the number and characteristics of the methods used to protect information; the number and categories of persons who can potentially be violators of information security rules; types of protected information. By calculating the security coeffcient of the object, it is possible to create an effective system of its information security and to optimize the choice of a set of technical means and methods of protection of information. It can signifcantly reduce the damage arising from the threats to information security. The method of mathematical modelling developed by the authors allows estimating the current level of information security in any organization of the fnancial sphere.

Published: November 2018

The review article positions the materials of the results of the VI International scientifc-practical conference, the content of which is considered from a special angle — through the phenomenon of market economies. Within the framework of the forum, the understanding of the past (in theoretical and applied terms) market model of management and the search for new sources of economic growth were carried out, the fnancial problems accompanying the genesis and evolution of economic life were discussed. The high level of discussion can be judged by the participation in the conference of such well-known post-Soviet scientists as R.M. Nureyev (Russia), B.S. Myrzaliyev (Kazakhstan), G.I. Ganush (Belarus), G.L. Sargsyan (Armenia), N.u. uzakov (uzbekistan) and others. In accordance with the program of the conference, special attention was paid to the analysis of debatable historical, economic, institutional, reproductive and transformational aspects of the phenomenon of the market system of management, explicated through the prism of monetary and fnancial relations. Materials of the conference actualize the development of evolutionary, institutional and interdisciplinary aspects of economic science, as a stage in the deepening of the existing system of knowledge about the phenomenon (objects) that make up the latest areas of Theoretical Economics, and their relationship, revealing a wide range of discussion of methodological and theoretical problems of the phenomenon of market economy. Of particular scientifc and practical interest are the opinions of the forum participants, reﬂecting the state and vectors of development of modern scientific knowledge in the feld of fnancial instruments of commodity-money relations, showing “bottlenecks” in this segment of economic science. A number of generalizing conclusions and recommendations are aimed at solving problems that are relevant to modern society, such as: strengthening the confrontation between the national and global economy, sanctions counteraction, contradictions of the traditional monetary economy and the emerging use of cryptocurrency. The results of the conference not only acquaint the academic and scientifc community with the trends in the study of the market phenomenon in the CIS but also have a signifcant potential applied interest.
5 financial System: an Integrated approach in the Context of the State financial Policy
Authors: Vorob’ev Yu.  N.  , Borshch L.  M. 
Published: November 2018

The purpose of our study was to substantiate theoretically and applied integrated approaches to the functioning and development of the fnancial system in the context of the state fnancial policy under the international sanctions. The study has been based on the theory of fnance, the dialectical method, and scientifc argumentation. We used a systemic approach, historical and economic-statistical methods as well. The authors substantiate the important scientifc direction of the modern fnancial system — modernization and progressive development and determine the consolidating functions of the state fnancial regulation, aimed at eliminating the imbalance, including new approaches to fnancing the budget defcit at the expense of borrowed funds. New approaches to macroeconomic orientation form new opportunities for modern modifcations in the fnancial system. On the basis of scientific arguments, the authors showed that although the federal budget of Russia plays a key role in the development of the fnancial system and the fnancial market, and the state fnancial policy acts as a macroeconomic regulator, the fnancial system of Russia develops on the basis of its own laws arising within it. The authors substantiate the point of view that the state fnancial policy is aimed at revealing the diversity of the functions of money circulation. This has an impact not only on social reproduction but also on the functioning and development of the fnancial system as a whole. The public fnancial policy should take into account the peculiarities of the functioning and development of the fnancial system in the context of constantly occurring macro-, meso-, and microeconomic processes. Of course, this will allow applying new approaches to modern changes in the fnancial system, and will also indicate the existence of a communicative convergent market, which is a sign of the formation of a “market of symbolic exchange of signs”, and hence of the new monetary changes.

Published: November 2018

Inflammation plays an important role in the development and progression of a variety of cardiovascular conditions,most notably coronary atherosclerosis and congestive heart failure. A number of inflammatory molecules have beenimplicated in these processes, including interleukin-1 (IL-1). IL-1 receptor antagonist is an endogenous inhibitor of IL-1, which competitively binds to the IL-1 type I receptor without activating it. Anakinra is a nonglycosylated, recombinantform of human IL-1ra that, like endogenous IL-1ra, competitively inhibits IL-1 by binding the IL-1 type I receptor.

Recent analyses of the Promontory Caves assemblages by Ives and colleagues (Billinger and Ives 2015; Hallson 2017; Ives 2014; Ives et al. 2014; Reilly 2015) have renewed interest in Julian Steward’s (1937) hypothesis that the thirteenth century inhabitants of the Promontory Caves have ties to Northern Dene language-speakers, thus shedding new light on Dene migration and Apachean origins. These studies have largely focused on the similarities between Northern Dene and Promontory moccasins, but other artifact classes—namely fibre perishables—have yet to be examined. This paper synthesizes conclusions drawn from the author’s prior research into matting and cordage recovered from the Promontory Caves in comparison to a neighboring Fremont cordage assemblage from the site of Lakeside Cave, with some suggestive differences emerging from material, structure, and knot types. These preliminary results suggest avenues for future comparative analyses of the Promontory perishable artifacts.

In industrial applications, requiring variable speed and load characteristics, the DC motor is the attractive piece of equipment; due to its ease of controllability. Pulse-width modulation (PWM) or duty-cycle variation methods are commonly used in speed control of DC motors. A simple, low cost, and efficient design for a control circuit uses the PWM to adjust the average voltage fed the DC motor is proposed in this paper. The objective of this paper is to illustrate how the DC motor's speed could be controlled using a 555 timer. This timer works like a changeable pulse width generator. The pulse width can be changed via relays to add or remove resistors in the timer circuit. Using relays enable the proposed circuit to drive higher-power motors. The designed circuit controls the speed of a Permanent Magnet PM DC motor by means of the parallel port of a PC; therefore, the user will be able to control the speed of the DC motor. C++ computer program is used to run the motor at four levels of speed. An interface circuit is used to connect the motor to the parallel port. PC based control software is chosen to get simplicity and ease of implementation.

Ayam broiler, adalah ayam pedaging cepat tumbuh yang mampu mencapai bobot badan 1100 â€“ 1.160 gram pada umur 30 hari. Untuk dapat mencapai tingkat produksi seperti ini diperlukan pengelolaan / pemeliharaan yang baik dengan menerapkan teknik beternak ayam pedaging yang benar. Masalah utama yang dihadapi oleh peternak ialah kelemahan peternak dalam pengetahuan (knowledge) dan pengalaman (experience) akan ketiga faktor pengelolaan usaha ternak, yaitu ; 1) Pemuliaan (breeding), 2) Makanan (feeding), dan 3) Tata laksana (management).

Masalah bibit ternak untuk saat ini telah dapat di atasi dengan tersedianya berbagai jenis bibit ternak unggul dan pakan ternak di pasaran, namun masalah pengelolaan/tatalaksana belum dikuasai dengan baik. Hal ini terlihat dari besarnya keragaman penampilan usaha peternakan ayam pedaging dari satu peternakan ke peternakan lain dan dari satu daerah ke daerah lain. Selain pendidikan dan pengalaman peternak, faktor keterbukaan peternak pada berbagai informasi baru adalah faktor penting dan perlu ditambahkan pada penelitian ini.

Tujuan yang ingin dicapai oleh penelitian ini adalah untuk mengetahui pengaruh pendidikan, pengalaman, dan keterbukaan pada informasi terhadap produktivitas usaha peternakan ayam pedaging di Kota Gorontalo.

Metode analisis data yang digunakan untuk menduga fungsi produktivitas usaha ternak yaitu dengan model fungsi regresi linier berganda. Variabel terpilih diuji dengan uji sidik ragam (Anova) dengan menggunakan tingkat kepercayaan 95 persen atau a = 5 persen (0,05). Untuk melihat variabel mana yang lebih besar pengaruhnya digunakan uji korelasi parsial. Sedangkan untuk melihat kemampuan model regresi dalam memprediksi/meramal variabel dependen (Y) dijelaskan dengan koefisien determinasi (R2) atau R-Square.

Berdasarkan penelitian dapat disimpulkan bahwa secara bersama-sama pendidikan responden, pengalaman responden, dan keterbukaan responden pada informasi berpengaruh nyata terhadap produktivitas. Secara parsial, pendidikan memberikan pengaruh tidak nyata, sedangkan untuk pengalaman dan keterbukaan pada informasi memberikan pengaruh nyata terhadap produktivitas. Model fungsi regresi yang diperoleh memiliki daya ramal/prediksi yang tinggi terhadap produktivitas peternak.

Aim: The aim of this study is to determine the
traditional practices of women for pregnancy, birth, puerperium and neonatal
care.Methods: This descriptive study was conducted in Amasya
Yeşilyenice Town. The sample of the study consisted of 134 females who had at
least one child, who lived in this region between 1 December and 15 January
2014 and who agreed to work. The written permission to conduct the study has
gotten from Yeşilyenice Municipality and verbally permission from the people
who join to the study. The participants were asked about their knowledge and
practice with a form prepared based on literature and consisting of 107 items
containing traditional practices.The data obtained in this study were analysed
with the SPSS 20 packet program. Ki squared with frequency and percentage,
Kruskal Wallis-H tests were used.Results: The average age of women is 48,87 ± 15,92 and
is between 19-80 years. All of the women stated that they have knowledge about
traditional practices. When they are asked to say them that come to their
minds, they have indicated the application of salting the baby, swaddling the
baby, “höllük” (putting soil under the baby's hip) and “kırklama” (a special
ceremony to bath when the baby is 40 days).

Conclusion: This study shows that although it changes over
time, traditional practices still continue. Nowadays evidence-based practices
have got a growing importance gradually. In that case useful traditional
practices should be developed and related trainings should be given more
importance.
