The results show that more than half of the participants (58 in number) agree to be more active in the classroom.
Gobernanza, estado de bienestar y políticas públicas.
Authors: De Gómez Pérez-Aradros Carlos Gil
Published: November 2018

Desde hace varias décadas en la Ciencia Política se habla de la crisis que los modelos tradicionales de gobierno están experimentando y de las nuevas y necesarias formas de interpretación de la realidad. Por mencionar algunas de estas quiebras, debemos tener presente que el Estado de bienestar está en crisis, la socialdemocracia en la UVI, la globalización nos hace pequeños, los modelos de gestión tradicionales de los asuntos públicos son absurdos e ineficaces, los Estados-nación se van disipando y las democracias representativas son criticadas por ineficientes. El cambio de paradigma pospuesto largo tiempo, debe incidir en la gobernanza social, que a su vez cuente con unas políticas públicas alejadas de las formas tradicionales de hacer gobierno, sin destruir el Estado de bienestar.

Los impuestos: algunas generalidades y su importancia social.
Authors: Hernández Becerril Brenda
Published: November 2018

Los impuestos constituyen el principal componente de los ingresos ordinarios que recibe el Estado mexicano con motivo del cumplimiento de sus actividades, a través de las cuales se permite la satisfacción de necesidades sociales. Éstos se han convertido en una herramienta macroeconómica clave para garantizar la estabilidad y hacerle frente, de alguna manera, a problemas de mayor envergadura, como el aumento exponencial de la pobreza. Ante esto, es fundamental entender el concepto de impuesto y sus diferentes acepciones, así como sus clasificaciones; de manera tal que ello permita rediseñar la política económica y plantear alternativas enfocadas a las políticas impositivas.
Confiabilidad y validez de un instrumento que mide el compromiso de trabajadoras sociales en instituciones de asistencia sanitaria
Authors: Carreón Guillén Javier , Hernández Valdés Jorge , Bustos Aguayo José Marcos , García Lirios Cruz
Published: November 2018

Los conflictos al interior de una organización suponen un desbalance entre demandas y recursos, oportunidades y capacidades, o bien, entre objetivos, tareas y metas que, desde un sistema conciliador requieren un clima de relaciones empáticas y de confianza vinculadas a un compromiso laboral. En ese sentido, el objetivo del presente estudio fue establecer la confiabilidad y la validez de un instrumento que mide el compromiso laboral. Para tal propósito, se llevó a cabo una investigación no experimental, transversal y exploratoria con una selección no probabilística de 125 profesionales del Trabajo Social adscritos a instituciones de salud comunitaria. Los resultados muestran que el factor supraordinal, es decir aquel
compromiso más allá del ámbito laboral, gremial y familiar explicó el 21% de la varianza. Se advierten líneas de investigación correlacional entre la socialización familiar, la formación profesional y la práctica laboral para establecer el ciclo del compromiso laboral y sus implicaciones en un estilo de liderazgo y dirección transformacional, pero conciliatorio de las asimetrías entre los empleados.

Rendición de cuentas y la gobernanza (2012-2018)
Authors: Matute González Carlos Fernando
Published: November 2018

Con los sistemas nacionales anticorrupción, de fiscalización y de transparencia, el gobierno acude a las prácticas de la gobernanza y se compromete más con la sociedad, siendo un gobierno más cercano y atento a las necesidades de los individuos y las comunidades. Una de estas necesidades es la rendición de cuentas a la que se sujetan las personas que reciben recursos públicos para generar certeza de que el presupuesto ejercido directa o indirectamente por el Poder Ejecutivo se emplea de la mejor manera. Para hacer efectiva esta rendición de cuentas, la Administración Pública Federal se apoya de varios instrumentos, como son la transparencia y la declaración patrimonial de los servidores públicos, mediante el uso de tecnologías de la información y comunicación.

This article aims to describe human philosophical thought of Ibn Miskawaih in the book entitled Tahdzib Alakhlaq which is focused on the conception of human being structure; the relation of human material substance (physic) and immaterial substance (soul); the human life ultimate; and the conception of Insan Kamil. Based on the library studies, by using content analysis approach, this study found the historical fact that Ibnu Miskawaih acknowledged; first, the existence of physical essence made human being bound by space, time, and material determination. While the existence of soul made human being be able to build a relationship with God and to create culture and civilization. Second the existence of a structural and functional relationship between physic as a material substance, and soul as an immaterial substance of a human being, and not human immaterial essential relationship. Third, the human life ultimate is to achieve ideal condition, related to their behavior and special characteristic, i.e. faculty of thought. Fourth, the conception of Insan Kamil which is emphasized to the force and magnificence of the faculty of thought that made human left their instincts, syahwiyah and amarah desire toward sharia law and wisdom of thought so that they would be able to achieve to the highest position in the human nature.
Decoupled centric and non-centric PWM techniques for open-end winding induction motor drive
Authors: Ranjit Mahamkali , Reddy Bramhananda , Suryakalavathi Munagala
Published: November 2018

This article proposes the space vector based decoupled centric and
non-centric PWM techniques for open-end winding induction motor drive. To
make the proposed configuration, 2-coventional inverters are fed on either
side of open-circuited stator winding of induction motor. Therefore three
level output is achieved. To obtain the control pulses for inverters in the
proposed configuration reference sinusoids are used. All the proposed PWM
techniques use the equal switching frequency. To obtain the validation for
the proposed work various theoretical and simulation analysis is carried out
using v/f control and the corresponding output voltage is verified
experimentally using 1HP asynchronous motor.
The mathematical model for analysis and evaluation of the transient process of the three-phase asynchronous machine performance
Authors: Markovic Nenad , Zivanic Jeroslav , Lazarevic Zoran , Iricanin Bratislav
Published: November 2018

This paper describes an adopted method which could be used in transient
process modelling of three-phase asynchronous machines on the computer.
Converter asynchronous electric machine feeding requires a detailed research
of the transient process influence and the dynamic states of energy exchange
between the electrical circuit feeding and the machine itself. A
mathematical model has been formulated in order to solve the transient
process of the three-phase asynchronous electric machine referring to the
two asynchronous machines and containing two matrix models defined by Park?s
d - q components. In the system of symmetrical components the state and the
operation of the first machine was defined based on relations and operation
conditions of a direct sequence system and of other machines based on
relations and operation conditions of an inverse sequence system. The new
method has been derived from the existing psbpwm MATLAB package. The new
model simulates the state and operation of a single machine with identical
parameters through the state and operation of the two machines with
identical parameters: the first in a direct sequence system and the others
in an inverse sequence system. Operation analysis of the three-phase
induction machine is limited to a transient process occurring in the right
angled shape of voltage feeding. The new presented model can, with certain
limitations, be applied not only to a three-phase asynchronous machine
model but to other alternating current machines which have a stator and a
rotor. The experiment has been performed following an example of
asymmetrical feeding followed by inverse component phenomena of electrical
and mechanical values in the machine.
The potential for the use of EEG data in electronic assessments

Published: November 2018

One of the most important goals of electronic assessments is to achieve the
smallest measurement error with tests that are as simple and short as
possible. The psychological state of an examinee is typically ignored, both
in the process of designing the tests and during the exam itself. Using the
developed framework, we tested 35 participants in an experiment to obtain as
much data as possible about the emotional states of the students depending
on the different types of question posed. In this paper, we present our
current results from an examination of the potential of using EEG data
towards applying artificial intelligence for improvement of electronic
assessments, as well as a technical platform for this purpose.

An Overview of the Main Phenomena and Trends that Accompanied the Development of Higher Education (1990-2013)
Authors: Sota Jani
Published: November 2018

This is now a well known axiom, that to judge the level of emancipation of a particular society, one should know the extent of her education. Because of the system’s nature, Albanian and foreign historiography has not been tackling a lot with the problems of higher education after 1990, seeing it from the perspective of the interests of the Albanian democratic state anyway, in terms of the transition, although with difficulties, efforts to change were not interrupted. The transition from totalitarianism to pluralist democracy and a free market economy also raised the issue of a radical change in the education field, a radical restructure, a radical democratic reform throughout work and life. Everything that happened after this period, especially in higher education, destroyed the “foundations” of the traditional high school influence by marxism-leninism, paving the way to new decentralized changes to achieve the highest quality indicators, through the step by step perfection of the university documentation, and efforts for the preparation of specialists, who are able to have direct access in manufacturing as well. The transformation of higher education began when our country was undergoing the transition period. In this study we will focus on the general analysis of the efforts of the Albanian government in front of incomplete standards in the higher educational system, reorganization of the school, in the framework of the change of the political system and the tranformation of socio-economic in Albania. Then it will be elaborated the intensity of changes and the results that are obviously noticed from one stage to the other, also some aspects of the reorganization process and the consolidation of higher education.
Quality Management, Standardization and Auditing Meet Multiple Organizational Risks, Strengthening Open Market Understanding and Social Responsibility
Authors: Baltos Georgios C. , Chomata Filippa S. , Vidakis Ioannis G.
Published: November 2018

This paper describes how the standardization essentially, rather than referring to goals, outputs and outcomes, addresses duties, roles and actions, while eventually the latter ones affect and empower the former. The quest for quality is still on-going in pursuit of effectiveness and efficiency combined with social responsibility, as long as it is dependent upon societies’ willingness to change the world and share a better future. Although organizations have a long way to walk toward synergism and integration, quality management is being transformed from compliance to collaboration driven. The wide range of standards implementing the quality management systems based on ISO 9001 materializes its strategic direction to be functionally adapted to specific sectors and industries. On the other hand, plenty of later standards deal with the additional requirements that are applicable only to specific industries. They surely carry pros and cons. There is, however, a threatening likelihood that the relevant markets would reject some of the standards in case multiple standards overlap each other, creating complex bureaucratic burdens. Health and Safety standards are a success story against such concerns, while a plethora of Control and Risk management standards compete each other, which may be perceived more as a source of creativity rather than confusion.
Public Perception of Flood Risks and Disaster Preparedness in Lagos Megacity, Nigeria
Authors: Onwuemele Andrew
Published: November 2018

Flood risks are considered as one of the most devastating natural disasters. Presently, flooding occurs in all the ecological zones in Nigeria which has been linked to global warming. In Lagos Megacity, the incidence of flooding is now a reoccurring decimal which is only an indication of the failure of the existing mechanism for flood risk reduction. Knowledge of public perception of flood risk is considered a crucial element for a proactive preparedness for flood risk reduction. This study is aimed at gaining insight into the public perception of flood risks for proactive flood risks preparedness among residents in flood prone areas in Lagos megacity, Nigeria. The survey research design was utilized. Data were collected by questionnaire from residents of flood prone neighbourhoods in the city. The results show high awareness of flood risks among respondents that have experienced flooding previously than respondents that have not experienced flooding in the past. It also reveals poor preparedness among respondents that have not experienced flooding. The paper calls for public awareness creation among residents in flood prone areas of the city as a strategy to promote preparedness for flood disaster risks reduction in the city.

Authors: Muja Aranit
Published: November 2018

The aim of this research paper is to study the properties of intraday returns, in a time range from one to fifteen minutes. In order to perform this analysis, we consider four sets of historical intraday returns for FTSE-MIB index. The first series consist of intraday returns with one-minute frequency, represented in log scale, which includes the period from 01.04.2011 till 30.09.2011. The consideration period for the other series does not vary, but the frequencies which we calculate the returns with, do. In detail, we took in consideration returns generated in 1, 5, 10 and 15 minutes. First, the study analyses the distribution of intraday returns by employing both graphical methods and moments calculation on different time scales. Secondly, the study analyses the returns maximum distribution on different time scales, checking the type GEV (Generalized Extreme value) returns distribution goodness of fit. The GEV parameters estimation was made by maximum likelihood using EVIM1 toolbox in Matlab.
New Technologies, Multiple Literacies and Teaching English as a Foreign Language
Authors: Cardoso Silene
Published: November 2018

This article presents and briefly discusses the results from a survey conducted with English teachers of the third cycle and secondary education in Portugal as part of a study on multiple literacies and Web 2.0 in English as a foreign language (EFL) classroom (Cardoso). Based on the answers provided, it can be assumed that among this group of teachers, new technologies tend to be part of their professional practice. However, it is unclear if digital tools have been used to actually promote more innovative ways of teaching or just as a different way to approach more traditional methods. Moreover, it seems that suitable guidance, training and further development of appropriate materials are required to facilitate and better integrate new technologies in the EFL classroom.
Interculturality in English Language Teaching – A Small Study with Portuguese Teachers
Authors: de Leão Ana Ponce
Published: November 2018

UNESCO and many other organisations worldwide have been working on approaches in education to develop tolerance, respect for cultural diversity, and intercultural dialogue. Particularly, the Council of Europe has laid out guiding principles in several documents to promote intercultural competence, following Byram’s and Zarate’s efforts in integrating this important component in language education. The commitment to developing the notion of intercultural competence has been so influential that many countries, e.g., Portugal, have established the intercultural domain as a goal in the foreign language curricula. However, this commitment has been questioned by researchers worldwide who consider that action is needed to effectively promote intercultural competence. The research coordinated by Sercu, for example, suggests that, although foreign language teachers are willing to comply with an intercultural dimension, their profile is more compatible with that of a traditional foreign language teacher, rather than with a foreign language teacher, who promotes intercultural communicative competence. In this study, I propose to examine teachers’ perceptions and beliefs about intercultural communicative competence in a cluster of schools in Portugal and compare these findings with Sercu’s study. Despite a twelve-year gap, the present study draws similar conclusions.
Effects of Heat and Mass Flux on MHD Free Convection Flow Through a Porous Medium with Radiation and First Order Chemical Reaction
Authors: Awasthi B.
Published: November 2018

The study of a magneto hydrodynamic (MHD) free convection flow of an incompressible viscous fluid flow past a vertical surface is analyzed by taking into account viscous dissipation under the influence of radiation effect and chemical reaction with constant heat and mass fluxes. The governing partial differential equations have been converted into a set of ordinary differential equations using non dimensional quantities. The perturbation technique has been applied to solve the system of partial differential equations. The velocity, temperature and concentration fields have been studied for the effect of the permeability parameter (α), Grashof number for heat transfer (Gr), Grashof number for mass transfer (Gm), Prandtl number (Pr), magnetic parameter (M), chemical reaction parameter (Kr), Schmidt number (Sc), Eckert number (E), radiation parameter (F) etc. The expressions for the skin-friction, rate of heat transfer and rate of mass transfer are also derived. It is observed that when the radiation parameter increases, the velocity increases near the vertical surface. It is also seen that the concentration decreases with an increase in the chemical reaction parameter (Kr).

Also, the effects of non-homogeneity and irregularity on the phase velocity of torsional surface waves have shown graphically.
Fractal Model of Transdermal Drug Delivery
Authors: Walicka A. , Iwanowska-Chomiak B.
Published: November 2018

Skin, separating the vital organs of a human body, is a desirable route for drug delivery. However, the intact skin is normally permeable only for drug molecules with a low molecular weight. The stratum corneum (SC), being the outermost layer of the skin and the epidermis being the second – more permeable – layer of the skin, play an essential function in transdermal drug delivery. Physical and chemical methods of skin poration are used to enhance transdermal drug delivery. Each poration leads to an irregular system of pores which are connected with a system of micro-capillaries passing through the epidermis. Both the systems by their irregularity form a fractal porous matrix. Drugs administrated by this matrix can be either suspensions and solutions or creams and gels, therefore they have to be modelled as non-Newtonian fluids.

To analyse the fluid flow through the porous matrix the model of the epidermis is assumed as gobbet-andmortar with the tortuous mortar of variable thickness and after transition from the mortar to the tube one considered classical and fractal capillary flows of selected non-Newtonian fluids.

Fractal expressions for the flow rate, velocity and permeability of fluids flow in a porous matrix are derived based on the fractal properties of the epidermis and capillary model. Each parameter in the proposed expressions does not contain any empirical constant and has a clear physical meaning and the proposed fractal models relate the flow properties of considered fluids with the structural parameters of the epidermis as a porous medium. The presented analytical expressions will help understand some of the physical principles of transdermal drug delivery.
An Analysis of Relations for Determining the Thermal Conductivity of Rigid Polymer Foams
Authors: Alsabry A. , Nikitsin V.I. , Kofanov V.A. , Backiel-Brzozowska B.
Published: November 2018

In the paper the authors present the effectiveness of the generalized thermal conductivity method for polymer foams, including modelling their geometrical structure. Calculations of the effective thermal conductivity coefficient λ are based on the generally accepted assumption of the additivity of different thermal exchange mechanisms in porous media and this coefficient is presented as a sum the coefficients of conductive λq, radiative λp, and convective λk thermal conductivity. However, in literature not enough attention is given to relations determined by means of the theory of generalized conductivity, including modelling the geometrical structure. This paper presents an analysis of these relations and verifies their ability to predict experimental data in comparison with the best formulae included in the paper [2].

Multiscale Fourier Landscape Pattern Indices For Landscape Ecology
Authors: Spivey Alvin , Vodacek Anthony
Published: November 2018

A factor analysis of 67 landscape pattern metrics was performed to quantify the ability of landscape pattern metrics to explain land cover pattern, and to report individual landscape pattern metric values that are statistically independent. This land cover pattern is measured from 7.68 x 7.68 [km] GeoTiff image tiles of the conterminous United States Geological Survey (USGS) 1992 National Land Cover Dataset (NCLD). Using factor analysis to rank independent landscape pattern information, each landscape pattern metric produces the explanatory power of that landscape pattern metric amongst the other 66 landscape pattern metrics—any landscape pattern metrics that report similar values contribute redundant information. The metrics that contribute the most information are Jackson’s Contagion statistic (P005), typically contributing to 97 % of the explained variability; the Fourier Metric of Fragmentation (FMF), typically contributing to 65 % of the explained variability; and average LCLU class lacunarity (TLAC), typically contributing to 62 % of the explained variability. Two other Fourier-based landscape pattern metrics we tested, the Least Squares Fourier Transform Fractal Dimension Estimation (LsFT) and the Fourier Metric of Proportion (FMP), contributed 50 % and 12 % to the explained variability, respectively. In addition, the values reported by each of the Fourier metrics are revealed to be relatively independent amongst commonly used landscape pattern metrics and are thus demonstrated to be appropriate for explaining general landscape pattern variability.

Authors: Siraj Mammo , Zhang Kebin , Moges Kidane
Published: November 2018

Assessing and quantifying the current forest resources status underpins sustainable forest resources planning and management. To this end, this study was conducted to analyze the dynamics of land use cover change (LUCC) and explore their drivers at the central highlands of Dry Afromontane Chilimo-Gaji forest for the study period (1973-2015) under consideration. The result of the study indicated that landscape trends have occurred in Chilimo-Gaji forest over the last 43 years and five classes of LUCC namely shrub land, rural settlement, bare land and road, forest land and agricultural land were identified. The most commonly reported drivers of deforestation in the study area were expansion of agricultural land, rural settlements, population growth, insecurity of the tenure and rights over the land, timber production and fuel wood collection. Surprisingly, the increasing demand for agricultural land and human settlement for increasing human population underpinned by expansion of agricultural activities led to the clearing of forest land in the study area. The study reveals that the forest land cover type has lost 922.14 hectares (26.96 %) which were changed into other land cover types such as agriculture and settlement for the study period under consideration with an annually rate of 21.45 ha. However, deforestation rates showed declining trend between the time periods 2008-2015 as a result of introduction of Participatory Forest Management (PFM) schemes (1996) which involve the local community in management and sharing of the benefit obtained from the management. In order to promote sustainable forest resources management in the study area in the years to come, integrated land use planning and management and addressing key drivers of deforestation were recommended.

Promoting the creation of Innovation Ecosystems: the case of the University of Porto
Authors: Melo Brito Carlos
Published: November 2018

Universities are increasingly acting as promoters of innovation, economic growth and regional development, a trend that has attracted the attention of both policy makers and researchers. The objective of this paper is to contribute to a deeper understanding of the role of higher education institutions as dynamic promoters of growth and development. The University of Porto is used as a case study to explore how universities can act as innovation ecosystems leaders and integrators. The main contributions of the paper are threefold. First, the case puts in evidence a key success factor: the talent to transform the knowledge produced by universities into valuable solutions for companies and other organisations. Second, links between universities and industry must assume a long-term and relational nature rather than an intermittent and transactional character. Finally, the success of university-based ecosystems depends on the integration of a diversity of actors, resources and competences. This means that a sustainable strategy of innovation and knowledge valorisation requires an approach that fosters both internal and external networking.

Published: November 2018

This research explores the impact of the firm’s characteristics of size and age on organizational innovation. The study is based on data gathered from a sample of industrial companies from central region of Russia, and reveals that there is a relation between the size and age of a firm and its organizational innovation activity. To make the research more specific, the organizational innovation is broken down into a few organizational innovation subtypes that are analysed independently. Each organizational innovation subtype of a firm demonstrates a different level of dependence on its characteristics. The conclusion was made that each subtype of organizational innovation must be analysed based on the specified context being considered.

Abstract: The higher education responding to the fourth industrial revolution (referred as "university 4.0") in this study is identified as a model of innovation – driven smart university. Here, the innovation is the philosophy, object as well as solutions for growing university’s values; while the concept of smart means the infostructure and technical conditions for running the teaching and learning activities based on advancements of 4.0 technologies. The core features of the innovation - driven smart university are described in the so-called "543" model, which consists of: entrepreneurial education (model “5 in 1”); innovation – driven academic researches; innovative ecosystem (model “4 in 1”); smart university; operating mechanism (model “3 in 1”); int  ernationalization and community responsibilities. The framework with criteria for the "university 4.0" model in accordance with quality assurance and university ranking approaches has been developed. Indicators for meeting these criteria can be used by universities for benchmarking themselves to QS 4-star standards or Top 200 universities in QS Asia university ranking table.

Keywords: University 4.0, smart university, innovation-driven university, innovative ecosystem, start-up, entrepreneurial spirit, cyber - physical system.
Determination of Base Flipping Free Energy Landscapes from Nonequilibrium Stratification

Published: November 2018

Correct calculation of the variation of free energy upon base flipping is crucial in understanding the dynamics of DNA systems. The free energy landscape along the flipping pathway gives the thermodynamic stability and the flexibility of base-paired states. Although numerous free energy simulations are performed in the base flipping cases, no theoretically rigorous nonequilibrium techniques are devised and employed to investigate the thermodynamics of base flipping. In the current work, we report a general nonequilibrium stratification scheme for efficient calculation of the free energy landscape of base flipping in DNA duplex. We carefully monitor the convergence behavior of the equilibrium sampling based free energy simulation and the nonequilibrium stratification and determine the empirical length of time blocks required for converged sampling. Comparison between the performances of equilibrium umbrella sampling and nonequilibrium stratification is given. The results show that nonequilibrium free energy simulation is able to give similar accuracy and efficiency compared with the equilibrium enhanced sampling technique in the base flipping cases. We further test a convergence criterion we previously proposed and it comes out that the convergence behavior determined by this criterion agrees with those given by the time-invariant behavior of PMF and the nonlinear dependence of standard deviation on the sample size.

In this article, the authors present a quantitative assessment of the consequences of a number of government decisions aimed at achieving accelerated economic growth, namely: 1) diversifcation of the economy; 2) reduction of the differentiation of regions; 3) increase of social protection of the population; 4) stimulation of the domestic demand. The authors used for calculations the modifed model complex developed in CEMI RAS. The complex includes a set of Computable General Equilibrium models (CGE models) and Agent-Based Models (ABMs). The author’s calculations showed, as compared with other industries, that the increase in fnancing of the sectors of the new economy leads for 7 years to the growth of GDP by 4.45 percentage points in relation to the basic version of the economy. We also established that due to tax preferences and differentiated investment policy in relation to the “problem” regions, it is possible to equalize the level of development of the subjects of the Russian Federation. The authors conclude that the process of inter-regional smoothing is time-consuming and a signifcant effect is possible after fve years from the beginning of the implementation of the relevant mechanisms. The results of the calculations showed that the increase in benefts as a whole leads to GDP growth and has a positive impact on the economic system. We also concluded that the reduction of the refnancing rate leads to an increase in GDP and lower inﬂation. With the help of the model complex, we calculated the inﬂuence of a number of illegal fnancial transactions on the main macro indicators. Quantitative assessment was carried out in three scenarios: 1) withdrawal of budget funds; 2) tax evasion by individuals and legal entities; 3) withdrawal of fnancial assets abroad. The unrealized GDP growth potential for the six years compared to the initial period was 11.107, 21.323, and 31.976 percentage points for the three scenarios, respectively. The calculations also show that almost any cash infusion into the real sector of the economy leads to GDP growth due to signifcant demonetization of the Russian economy.

Hypercholesterolemia is complication in type 2 diabetes. Alpha lipoic acid (ALA) reduced total cholesterol by modulatingcholesterol synthesis pathway and reduced cholesterol biosynthesis genes expression. The goal of this research wasto investigate the prohibition of hypercholesterolemia in type 2 diabetes rat by ALA. Fifteen adult male wistar rats (2-3 months, 200-250 g body weight) were segregated into three groups (standard, type 2 diabetes and type 2 diabetes +ALA). Type 2 diabetes induced by streptozotocin 65 mg/kg and nicotinamide 110 mg/kg. ALA was given for 3 weeksafter type 2 diabetes induced.After 31 days total cholesterol of groups labelled is measured. The result showed therewas significant difference between ALA and type 2 diabetes groups (p= 0.012), and there was no significant differencebetween ALA and standard groups (p= 0.591). As the conclusion, this study proves that ALA has effects on totalcholesterol in type 2 diabetes rats.
