Published: January 2018

Objective: The aim of this study is to analyze the interrelationship and pattern of electrolyte imbalance and compare the correlation between serum electrolytes, glycosylated hemoglobin (HbA1C), and hemoglobin (Hb) levels between Type 2 diabetic patients and non-diabetic subjects.Methods: This study was conducted in 300 subjects (150 diabetics and 150 non-diabetics) and further categorized as anemic and non-anemic within each group. Blood samples were analyzed for HbA1C, hemoglobin, and serum electrolyte levels.Results: Sodium (Na+) levels in diabetics were significantly lower and potassium (K+) as well as chloride (Cl−) levels were significantly higher, when compared with non-diabetics. A significant positive correlation between HbA1C and potassium as well as chloride levels in contrast to negative correlation with sodium levels was observed in both genders. Among diabetics with anemia, we found significantly lower sodium and higher potassium and chloride.Conclusion: In diabetics, levels of sodium were significantly lower, and potassium as well as chloride was significantly higher when compared with non-diabetics. Our study clearly demonstrates an association between electrolytes, hemoglobin, and HbA1C levels in diabetes. This insight should pave the way for pathophysiology-directed therapy, thus contributing to the avoidance of several deleterious effects associated with electrolyte disorders and their treatment.

STEREOCHEMISTRY - RACEMIC MODIFICATION, RESOLUTION, AND ITS IMPORTANCE WITH RECENTLY USED OPTICALLY ACTIVE DRUGS.
Authors: Baregama Chetna
Published: January 2018

Stereochemistry involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation. An important branch of stereochemistry is the study of chiral molecules. Optical activity is the ability of a chiral molecule to rotate the plane of plane-polarized light, measured using a polarimeter. Racemic modification and resolution, both processes are very important in stereochemistry. A mixture of equal parts of enantiomers is called a racemic modification. The process of separating a racemate into pure enantiomers is known as resolution. Recently, various optically active drugs are used for the treatment for various diseases. In these drugs, some are used as mixture of enantiomers and some used as single enantiomer. For preparation of optically active drugs, racemic modification and resolution processes are generally used. Hence, this is very important to know about various steps and types of processes used for the same. Racemic modification is advantageous where racemates have more therapeutic advantages than single isomers. Resolution is advantageous where single entiomer is used for treatment because single enantiomers have less complex and more selective pharmacodynamic profile as compared to racemic mixture so have lesser adverse drug reactions, improved therapeutic profile, less chances of drug interactions than racemic mixtures. Recently used optically active drugs are amlodipine, atenolol, cetirizine, ketamine, metoprolol, omeprazole, pantoprazole, salbutamol, propranolol, clopidogrel, rabeprazole, citalopram, ibuprofen, ketoprofen, zopiclone, etodolac, salbutamol, and nateglinide.

Authors: Kravtsovа V.I. , Chalova E.R.
Published: January 2018

The Anapa bay bar is a valuable recreational and medical resource. Digital landscape and morphological mapping of its the North-Western part was created by digital aerial survey materials for monitoring its statement. The compiled maps show that in the Western part of region dune belt is degraded; the front dune hills were destroyed due to spreading the settlement of Veselovka buildings to the beach, and due to mass enactments carrying out at the bay bar of lake Solenoye. Here it is necessary to solve the problem of defense from waves flooding by constructing artificial hills. The middle part of the region, around the Bugaz lagoon, is used for unregulated extremal sports such as windsurfing and kiting, seasonal recreation in tent-camping and public events. Many short roads to the sea beach, orthogonal to the coast line, have turned into corridors of blowing and sea waves’ interaction with lagoon lowland destroying the dune belt. In the Eastern part of the region, at the Bugaz bay bar, the dune belt is conserved, but it changes under natural sea and wind processes action. In some places sea waves erode the windward front dune slope. Just everywhere sand accumulative trains are formed at the leeward slope of the front dune. It is shown that peculiarities of landscape morphological structure mast be taken in account due to taking measures for the bay bar protecting and preservation.
Analysis of uncertainty of remote estimates of soil humidity by the aim of authentic prediction of flooding
Authors: Danziyev R.M. , Litvinov N.Yu.
Published: January 2018

The multiple cases of flooding are known which are stimulated by processes of urbanization and wrong agricultural policy. Flooding leads to demolishing of spatial fertile layers of the earth which in its turn causes the erosion of land. Methods of remote sensing allows to obtain the information on humidity of the land cover in wide geographic regions. The soil humidity is measured usually using microwaves radiometers, because there is a sufficiently strong interrelation between soil humidity as far as depth of 5 cm and brightness temperature. The soil humidity is measured also by help of remote sensing meters operating in visible/infrared zone of spectrum, including measurements of NDVI in visible/near infrared band and the land spatial temperature in thermal band. In the article the analysis of uncertainty of remote estimates of soil humidity is carried out by the aim to predict the flooding authentically. It is noted that uncertainty calculation of the soil spatial cover humidity leads to uncertainty of prognosis of possible inundation. The questions on forming of uncertainty in measurements of spatial covering of soil, spatial temperature of soil an the soil humidity. The models for carrying out of series of measurements on relevant schemes are developed for obtaining data on the soil humidity with minimum uncertainty are developed.

Authors: Bibaeva A.Yu.
Published: January 2018

The paper describes the methodology for processing remote sensing data to indicate pyrogenic effects on natural geosystems. Autumn season space images (from the end of the firedangerous period to the beginning of the formation of the snow cover – the end of September to the beginning of October) with a less than 20 % cloud level were preferred. The area affected by fires within Priolhonye in the period since 2013 to 2015 years are analyzed. According to the obtained data it has made more than 200 km2. Pyrogene impact on Priolkhonye geosystems considerably amplifies amidst transforming environmental factors (climate warming, decrease in water level of the Lake Baikal and all that) and anthropogenic impacts, that is lead to change in the structure and rate of physiographic processes. In the conditions of the changing environment of geodynamic active area this impact on Priolhonye geosystems can be disastrous and lead to their irreversible transformation. In particular, disturbed geosystems of cedar forests by fire will could change to pine-larch forests through the birch series. In particular, the destructive effect of the pyrogenic factor on steep slopes with pine-larch rarefied groups of facies leads to the destruction of its invariant structure and replacement by steppe small-graingrassy lithophilic ones.

The Call for Islamic Economics: Shades of Contestation
Authors: Ibrahim Azhar
Published: January 2018

This paper attempts to highlight some of the criticisms made against the ideas of Islamic economics. The discourse of Islamic economics is relatively recent, although its expression could be traced to more than five decades ago. Today there are countless discussions and affirmations for Islamic economics, coming from both experts in the area of economy and Islamic legal thought, apart from the many journalistic advocacy type that is enamored by the call for the establishment of Islamic economics, or at least the Islamic banking. While there is much celebration to this idea, the criticism against it is far less and hardly noticeable. To date, Timur Kuran and to some extent Nazih Ayubi have been vocal in highlighting the rhetorics and the insubstantiality of the idea of Islamic economics.Keywords: Islamic economics, Islamic identity, sharia

Published: January 2018

Fraud is an epidemic dimension that has eaten deep into the banking sector as well as the entire economics in Nigeria. Its devastating effect manifests itself in the deteriorating balance sheet of banks as well as in economic backwardness. Apparently, measures to detect and eradicate fraud in banking sector have been quite ineffective as the fraudulent practices have been on the increase in recent times. Thus, this study evaluates the various challenges of detecting and combating fraud in the banking sector in Nigeria. The results from the descriptive analysis showed that lack of adequate motivation is not a major cause of fraud in banks, looting of fund by bank managers and directors constitutes the major form of fraud in Nigeria. Furthermore, it is recommended that government should strengthened existing anti-graft agencies and to enhance their financial independence. Those managers and director involved in looting of fund should be persecuted to serve as a deterrent to potential fraudsters. In addition, bank staff should be properly screened to test their morality and integrity before recruitment. Adequate internal control mechanism should be established to serve as check and balances among the bank staff. There is also the need for the anti-graft agencies to be strengthened in order to adequately complement the effort of the Central Bank of Nigeria (CBN) at nibbling the incidence of bank fraud in the bud.Keywords:  banking system, fraud, fraud detection, fraud prevention, Nigeria
Flypaper Effect of Regional Expenditures in Yogyakarta
Authors: Rudi Muh
Published: January 2018

One of the consequences as a  result of the implementation of regional autonomy is that local governments must have sufficient financial resources to pay their autonomy government. The financial capacity of local governments would determine the ability of local governments to perform the functions of government. Considering Article 5 of Law No. 33, 2004, sources of regional revenue are regional revenues, balance funds/ transfers and financing. When local revenue comes from the transfers, the stimulation of expenditure is different from the stimulation that arises from local revenue (especially local taxes). This study focuses on identifying the flypaper effect on expenditure areas and its classification with samples of five districts and cities in Yogyakarta during 2006-2015. This paper argued that during the period among flypaper did not occur in the expenditure area and sub expenditure areas. In addition, flypaper found only in capital expenditure, while expenditure is not a suspect. Keywords: flypaper, autonomy and fiscal needs, local autonomy, Yogyakarta

Published: January 2018

Wireless Sensor Network (WSN) can be applied for Air Pollution Level Monitoring System that have been determined by the Environmental Impact Management Agency which isÂ  PM10, SO2, O3, NO2 and CO. In WSN, node system is constrained to a limited power supply, so that the node system has a lifetime. To doing lifetime maximization, power management scheme is required and sensor nodes should use energy efficiently. This paper proposes dynamic sleep scheduling using Time Category-Fuzzy Logic (Time-Fuzzy) Scheduling as a reference for calculating time interval for sleep and activated node system to support power management scheme. This research contributed in power management design to be applied to the WSN system to reduce energy expenditure. From the test result in real hardware node system, it can be seen that Time-Fuzzy Scheduling is better in terms of using the battery and it is better in terms of energy consumption too because it is more efficient 51.85% when it is compared with Fuzzy Scheduling, it is more efficient 68.81% when it is compared with Standard Scheduling and it is more efficient 85.03% when compared with No Scheduling.

Authors: Aaditya Angga Wahyu , Happyanto Dedid Cahya , Sumantri Bambang
Published: January 2018

Indirect Field Oriented Control (IFOC) is one of the vector control methods that can be applied to induction motor in the industrial world rather than Direct Field Oriented Control (DFOC) because of the flux is obtained from the formulation. However, IFOC can not guarantee the robustness and stability of the systems. Stability analysis such as Lyapunov Stability Theory can be used to make the system stable but not the robustness. Model based controller that can guarantee the stability and robustness such as sliding mode control (SMC) and fuzzy needs to be added in IFOC system to achieve proportional response system. Robust current regulator using sliding mode control was designed in this paper from state space model for model based controller. In transient response and under disturbance SMC shows better performance than PID in rising time and robustness at rotor speed and stator current.

Published: January 2018

This research will discuss a strategy of frequency control at micro hydro power plant using Capacitive Energy Storage (CES). CES is a device that can store and release energy quickly. To optimize CES performance, proper tuning is required to optimize CES performance. To obtain optimal CES parameter on micro hydro, artificial intelligence method based on Imperialist Competitive Algorithm (ICA) is used. Proportional Integral Derivative Controller (PID) is still a controller that can not be separated from the system, therefore in this research will be combined with CES as the main controller for frequency control on micro hydro. The simulation results show that the application of ICA in optimizing PID-CES parameters, can well improve micro hydro performance. The control models discussed in this research are Proportional Controller (P), Proportional Integral Controller (PI), Proportional Derivative Controller (PD), PID Controller, CES Controller and PID-CES Controller. From the simulation results obtained, P controller overshoot of -0.0001254, with PI Controller -0.000125, with PD Controller -0.0001252, with PID controller -0.0001249, with CES controller -0.0001224, and with PID-CES -1.371e-05. From the results of some of the controller models, it can be concluded that the PID-CES controller proposed in this study has a very significant effect to reduce the frequency oscillation in micro hydro, and it is very suitable to be applied for frequency control at micro hydro.

Published: January 2018

As the WHO says, heart disease is the leading cause of death and examining it by current methods in hospitals is not cheap. Iridology is one of the most popular alternative ways to detect the condition of organs. Iridology is the science that enables a health practitioner or non-expert to study signs in the iris that are capable of showing abnormalities in the body, including basic genetics, toxin deposition, circulation of dams, and other weaknesses. Research on computer iridology has been done before. One is about the computer's iridology system to detect heart conditions. There are several stages such as capture eye base on target, pre-processing, cropping, segmentation, feature extraction and classification using Thresholding algorithms. In this study, feature extraction process performed using binarization method by transforming the image into black and white. In this process we compare the two approaches of binarization method, binarization based on grayscale images and binarization based on proximity. The system we proposed was tested at Mugi Barokah Clinic Surabaya.Â  We conclude that the image grayscale approach performs better classification than using proximity.

Published: January 2018

Humanoid research in Indonesia is quite a lot, but in reality only limited in kid-size proportional size, while for the Teen-Size is still rare. Research on the Teen-Size Humanoid robot requires more joints to be able to perform the movement compared to the size of Kid-Size, therefore required more complex modeling to determine the movement. With complete kinematics anlysis, the movement of the robot can be solved. With kinematic forward-invers, researchers can determine the movement of robots by controlling the motor parts that function as a joint on the robot. In this study, the modeling uses D-H parameter, because this modeling has been widely used, besides the calculation can be solved by computing. And then for the simulation can be done with V-REP software. Forward-invers kinematics can be implemented on the PID algorithm, in order to generate speed on the motor that can form an angle on the motor to make the movement. The result of this research is to obtain equation of matrix transformation from all body parts of robot. With the creation of this Humanoid Teen-Size robot, it is hoped that the research on Humanoid robot in Indonesia will be increasingly diverse and increasing, and can be used as a support and reference in the development of Humanoid Teen-Size next.

Um Panorama da Pesquisa Internacional sobre Mudança Conceitual
Authors: Pereira Alexsandro Pereira de
Published: January 2018

Apresentamos quatro distinções básicas para revisar a pesquisa internacional sobre mudança conceitual: (1) as abordagens clássica e reenquadrada à mudança conceitual; (2) as perspectivas da coerência e da fragmentação do conhecimento intuitivo; (3) as tendências frias e aquecidas na pesquisa em mudança conceitual; (4) as abordagens cognitiva e situativa à cognição humana. De acordo com essas distinções, a mudança conceitual não é uma substituição de uma concepção por outra, mas sim o uso de uma concepção adequada de acordo com o contexto. Além disso, as concepções são descritas não apenas em termos de estruturas do tipo teoria, mas também em termos de conhecimento em pedaços. Adicionalmente, a mudança conceitual não é vista como um processo puramente racional, mas sim como algo que envolve aspectos motivacionais e fatores contextuais de sala de aula. Finalmente, a mudança conceitual envolve não apenas a mente individual, mas também um conjunto de artefatos e sistemas simbólicos disponíveis em contextos socioculturais particulares.

Os procedimentos metodológicos destacam: a construção de enunciados híbridos e sua arquitetura dialógica, semântica, sintática e iterativa; o desenvolvimento de atividades com linguagens, imagens e afirmações da literatura e a direção de analisar e organizar o conteúdo epistemológico em cinco eixos/textos: os saberes e seus contextos, linguagens, práticas, teorias e representações. Esse conjunto de recursos é destinado aos que querem aprofundar seus conhecimentos sobre as relações entre saberes culturais locais e científicos, destacando a mistura de linguagens como forma de comunicar os conteúdos, a ausência de voz autoritária nesta construção e a indissociável relação entre conhecimento e contexto para as tarefas de representação e comparação epistemológica dos saberes.
The Construction of the Science in the Community Website: Antecedents, Foundations, Hybrid Narratives and Epistemological Content
Authors: Pinheiro Paulo César
Published: January 2018

The article presents the antecedents and foundations which led to the construction of the website Science in the Community, a virtual environment just created to share experiences on local cultural knowledge using the internet. Initially, it describes the proposal of folk knowledge insertion into chemistry and science education in Brazil and other related emphases in the international literature, highlighting teachers’ education, its problems and a debate involving indigenous knowledge and the nature of science. Next, it describes the results of empirical inquiries in classrooms and the convergence with literature to offer epistemological content for teachers based on hybrid narratives. As a theoreticalbackground, it presents the concepts of hybridization/hybridism, of narrative and the epistemological dimension of the analysis carried out. The methodological procedures emphasize the construction of hybrid utterances and their dialogic, semantic, syntactic and iterative architecture; the development of activities on languages, images, assertions from literature, and the way the epistemological content was analyzed and organized according to five axes/texts: the knowledges and their contexts, languages, practices, theories, and representations. This set of resources is for those who want to deepen their knowledge on local and scientific knowledge relationships, underlining the mixing of languages as a way to communicate both contents, the absence of authoritarian voice on such a construction and the inextricable link between knowledge and context for the task of knowledge’s representation and epistemological comparison.
Perspectivas de Comunicação Pública da Ciência em Editais e Chamadas Públicas sobre Biodiversidade no Brasil
Authors: Oliveira Denise de , Giroldo Danilo , Marandino Martha
Published: January 2018

A presente pesquisa investigou editais e chamadas públicas sobre Biodiversidade do Conselho Nacional de Desenvolvimento Científico e Tecnológico – CNPq, com a intenção de compreender a integração entre o fomento à pesquisa e a divulgação científica ou popularização da ciência. Para tal, considera a relevância do incentivo às relações entre ciência e público em um País de megadiversidade e que enfrenta perdas e ameaças à biodiversidade e à diversidade cultural em todos os biomas brasileiros. Com base no referencial teórico dos modelos de comunicação pública da ciência, bem como por meio da aplicação da análise textual discursiva, foram analisados 32 editais e chamadas relacionados à biodiversidade, no período de 2005 a 2012, pontando perspectivas de comunicação pública da ciência em três grandes grupos: Informacional, de Diálogo e de Participação, cada qual revelando características próprias quanto à forma de socialização do conhecimento, concepção de ciência, concepção de público e de arranjos institucionais. Houve predominância do modelo informacional, em que a transferência do conhecimento é dirigida à sociedade e ao público em geral, de modo unidirecional, bem como de modelos mistos, em que a perspectiva informacional esteve associada à de diálogo e à de articipação. Os resultados da pesquisa ampliaram a compreensão das ações de fomento à pesquisa sobre biodiversidade que vêm sendo integradas à divulgação e educação em ciências, dando margem ao aprimoramento de futuras ações, tanto de pesquisadores como de formuladores de editais, sobre a intenção de fortalecer o protagonismo da sociedade nos rumos da ciência e na conservação da biodiversidade.
Discursos sobre Física Contemporânea no Ensino Médio a partir da Leitura de Textos de Divulgação Científica
Authors: Silva Wagner Moreira da , Zanotello Marcelo
Published: January 2018

Esta pesquisa empírica e qualitativa investiga o uso de textos de divulgação científica (TDC) para abordar temas controversos relacionados à física contemporânea no ensino médio. O objetivo principal consiste em analisar os sentidos construídos pelos estudantes a partir da leitura dos TDC, organizada através de roteiros que solicitam respostas por escrito a questionários e a realização de seminários em sala de aula. O total de 53 alunos do terceiro ano de um colégio particular localizado na cidade de São Paulo realizaram as atividades programadas em um período de seis aulas. Com base no referencial teórico daAnálise de Discurso francesa, a produção dos estudantes evidencia o desenvolvimento de posicionamentos críticos sobre aspectos da prática científica e a compreensão de certos conceitos físicos associados às temáticas abordadas.
Fundamentos Pedagógicos para o Uso de Simulações e Laboratórios Virtuais no Ensino de Ciências
Authors: Paula Helder de Figueiredo e
Published: January 2018

Como podemos interpretar possíveis contribuições dos aplicativos de computador que contêm animações, simulações e laboratórios virtuais a partir de uma perspectiva sócio-histórica do ensino e da aprendizagem? Como identificar as potencialidades e as limitações desses aplicativos? Com quais demandas os estudantes são confrontados durante o trabalho de interpretação de representações complexas por meio das quais fenômenos e modelos das ciências são apresentados nesses aplicativos? Quais critérios podem ser usados para distinguir animações, simulações e laboratórios virtuais? Como podemos usar aplicativos que contêm simulações e laboratórios virtuais em uma perspectiva de ensino por investigação e por que vale a pena seguir essa orientação? Essas questões são apresentadas e discutidas ao longo das várias seções que compõem este artigo e nas quais nós apresentamos e utilizamos um conjunto de referenciais teóricos cujo valor para o enfrentamento das questões nós procuramos sustentar. Como estratégia argumentativa, recorremos à análise de alguns aplicativos disponíveis em sites bastante conhecidos por professores e por pesquisadores que se dedicam ao ensino e à aprendizagem das ciências.
Representações Pictóricas em Manuais Escolares de Geologia do Ensino Secundário: um Estudo no Âmbito do Paleomagnetismo
Authors: Correia Gina Pereira , Gomes Celeste Romualdo
Published: January 2018

As representações pictóricas (RP) são fundamentais nos manuais escolares e, em particular, nos do ensino das ciências. A sua eficácia e valorização para o ensino e aprendizagem devem centrar-se na forma como estão integradas e contextualizadas,de modo a potenciar uma relação adequada com a linguagem verbal. Neste estudo apresentam-se os resultados obtidos a partir de uma avaliação qualitativa a manuais de Biologia e Geologia do 10.º ano (n=5) e de Geologia do 12.º ano (n=3) do sistema de ensino português. Sobre o Paleomagnetismo formulou-se a seguinte questão de investigação: no capítulo sobre paleomagnetismo, os manuais escolares de Geologia evidenciam uma organização e estruturação coerentes das RP para ensino e aprendizagem? Para dar resposta a esta questão definiram-se os seguintes objetivos e com os quais se pretende avaliar: a relação de ‘comunicação’ entre as RP e a linguagem verbal nos subcapítulos analisados; o predomínio das tipologias das RP; a presença de legenda e escala nas RP. A análise dos resultados permite-nos concluir que as RP são muito importantes no ensino das geociências, quer como complemento ao texto explicativo, quer no apoio às atividades práticas. No entanto, nem sempre estão apresentadas da melhor forma, dando origem a uma aprendizagem menos efetiva dos conteúdos geológicos ou podendo induzir a conceções erradas nos estudantes.
Pictorial Representations in Geology Textbooks of High School: a Study in the Scope of the Paleomagnetism
Authors: Correia Gina Pereira , Gomes Celeste Romualdo
Published: January 2018

The pictorial representations (PR) are fundamental in textbooks, particularly to those regarding the Sciences education. Their efficiency and value for the teaching and learning processes must be focus not in their quantity, but in the way they are linked and integrated, so that it can create an adequate relationship with the verbal language. This study presents the results obtained from a quantitative evaluation of Biology and Geology textbooks of the 10th grade (n=5) and Geology of the 12th grade (n=3) of the Portuguese education system. The chosen topic was Paleomagnetism and it was formulated through the following research question: in the chapter concerning Paleomagnetism, do the Geology textbooks show a consistent organisation and structuring of the PR for the teaching and learning processes? To answer this question, the following goals were defined, which should be able to evaluate: the relationship of “communication”between the PR and the verbal language in the previously evaluated subchapters; the prevalence of the PR typologies in the observed sample; the presence of legend and scale in the considered PR. The results allow us to conclude the importance that PR has in the Geosciences teaching as a complement to the explanation text, and as a support to the practical activities. However, there are evidences of the lack of rigor in the use of these representations, which can lead to the possibility of a less effective learning of geological subjects or may lead to erroneous conceptions in students.
