Authors: Birsyada Muhammad Iqbal
Published: May 2017

The history of the collapse of the Majapahit showed the discourse of power. In this context  rule has been supporting a particular version of historical knowledge. Applying  historical method and multi-dimensional approach, this study aims to find out why the knowledge about the collapse of Majapahit spreading among community members was more tended toward the version that Girindra-wardhana  as a single actor who overthrow Prabu Brawijaya V. The results of this study indicated  that the knowledge  among Javanese  community about the collapse  of Majapahit that stated Girindrawardhana as the sole actor that attacked  and subverted  the kingdom of Majapahit which at the time was ruled by King Kertabhumi (Brawijaya V) is supported by a wide range of all power of the ruling elite that were largely due to ideological motives. Power and ideology are used as a means of legalizing knowledge.

Two different air-cathode stacked microbial fuel cell (MFC) configurations were evaluated under continuous flow during the treatment of municipal wastewater and electricity production at a hydraulic retention time (HRT) of 3, 1, and 0.5 d. Stacked MFC 1 was formed by 20 individual air-cathode MFC units. The second stacked MFC (stacked MFC 2) consisted of 40 air-cathode MFC units placed in a shared reactor. The maximum voltages produced at closed circuit (1,000 Ω) were 170 mV for stacked MFC 1 and 94 mV for stacked MFC 2. Different power densities in each MFC unit were obtained due to a potential drop phenomenon and to a change in chemical oxygen demand (COD) concentrations inside reactors. The maximum power densities from individual MFC units were up to 1,107 mW/m2 for stacked MFC 1 and up to 472 mW/m2 for stacked MFC 2. The maximum power densities in stacked MFC 1 and MFC 2 connected in series were 79 mW/m2 and 4 mW/m2, respectively. Electricity generation and COD removal efficiencies were reduced when the HRT was decreased. High removal efficiencies of 84% of COD, 47% of total nitrogen, and 30% of total phosphorus were obtained during municipal wastewater treatment.

Published: May 2017

Twelve postpartum Jafarabadi buffaloes of University farm were examined gynaecologically
between months of February and May 2016 and were found to be either anestrus with smooth
ovaries (n=8) or subestrous (n=4) with functional corpus luteum. All the 12 animals irrespective of
ovarian status were injected i/m with Busreline acetate 20 μg (Receptal, 5 ml) on day 0, Cloprostenol
500 μg (2 ml) on day 7 and were inseminated twice after 72 and 84 hrs. Second injection of Receptal
2.5 ml was given at the time of 2nd insemination. Six buffaloes returned to estrous on 21st day following
insemination which were reinseminated twice at 12 hours interval on reported estrous and injected
with 2.5 ml Receptal. Pregnancy diagnosis was done two month post-insemination and conception
rate of 50.00% (6/12) to first insemination and 33.33% (2/06) to second insemination was obtained.
The overall conception rate obtained was 66.66% (8/12). Thus from the above facts, it can be said
that this schedule of modified GnRH-PG-GnRH appears to work effectively in infertile Jafarabadi
buffaloes with good conception rate.

Published: May 2017

Congenital anomalies, and less frequently multiple congenital anomalies, are encountered in
domestic animals, which in turn may cause obstetrical problems (Noakes et al., 2002). Schistosomus
reflexus is characterized by anomaly of the trunk with actual angulation of vertebral column,
herniation of abdominal organs and skeleton defects leading to dystocia. Only cases that display
both visceral exposure and spinal inversion are considered as true Schistosomus reflexus (Laughton
et al., 2005). The condition is a type of monstrosity reported most commonly in cattle (Knight, 1996;
Kalirajan and Rani, 2016; Prabaharan et al., 2016), buffalo (Kumar et al., 2012), sheep (Mukasa-
Mugerwa and Bekele, 1989) and goats (Barman et al., 2010). The prevalence of Schistosomus
reflexus is believed to occur in cattle from as low as 0.01% (Sloss and Johnston, 1967) to 1.3%
(Knight, 1996).

Heat and mass transfer effects on the peristaltic flow of Sisko fluid in a curved channel
Authors: Ahmed Raheel , Ali Nasir , Javid Khurram
Published: May 2017

In the present study heat and mass transfer phenomena in flow of non-Newtonian Sisko fluid induced by peristaltic activity through a curved channel have been investigated numerically using an implicit finite difference scheme. The governing equations are formulated in terms of curvilinear co-ordinates with appropriate boundary conditions. Numerically solution is carried out under long wavelength and low Reynolds number assumptions. The velocity field, pressure rise per wavelength, stream function, temperature, and concentration fields have been analyzed for the effects of curvature parameter, viscosity parameter, and power law index. Additionally, the computation for heat transfer coefficient and Sherwood number carried out for selected thermophysical parameters. The main results that are extracted out this study is that for strong shear-thinning biofluids (power-law rheological index, n < 1) the flow exhibits the boundary-layer character near the boundary walls. Both temperature and mass concentration are found to increase with increasing the generalized ratio of infinite shear rate viscosity to the consistency index. The amplitude of heat transfer coefficient and Sherwood number is also an increasing function of generalized ratio of infinite shear rate viscosity to the consistency index.

Published: May 2017

In the upcoming years, an opportunity for a wide range of electricity management solutions arises, thus several researchers have focused their efforts on studying and analyzing various subjects related to the operation of microgrids, smart grids, Vehicle-to-Grid (V2G), responsive demand, among others. On the other side, especially at engineering courses, these topics are primarily covered from a theoretical standpoint only, without a complementary laboratory approach. To this end, this work considers the development of a small-scale prototype consisting of a set of hardware and software tools that enable the students, either in an undergraduate or postgraduate level, to have a better understanding of the operating principles of these concepts. In this context, various distributed energy resources, including a mini photovoltaic panel, a mini wind generator, a stationary battery, an electric vehicle model, as well as household loads, are collectively run by a central control unit in the form of a Virtual Power Plant. This paper presents the design and development of the hardware and software platform for simulating the operation of a Virtual Power Plant, which serves as the base for a Remote Lab for educational purposes.

Comparative study of calorific value of rapeseed, soybean, jatropha curcas and crambe biodiesel
Authors: Oliveira, L.E.  , Da Silva M. L. C. P.
Published: May 2017

Biodiesel is a mixture of esters of short chain alcohols, produced as an alternative fuel for mineral diesel substitution. It is originated from renewable sources (fats and oils) and is less pollutants. But for its implementation, it is necessary to analyze some important quality parameters. A very important fuel`s feature is the calorific value, which represents the amount of heat transferred into the chamber during the combustion and indicates the available energy in fuel. The calorific value is obtained experimentally using a calorimetric bomb. The higher the calorific value, the higher is the yield of the fuel. The aim of this study is to determine the calorific value of rapeseed, soybean, jatropha curcas and crambe biodiesel using a calorimetric bomb. The results were associated with the ethyl ester composition of each biodiesel. The crambe biodiesel shows the highest calorific value (∆H= 40564 J g-1) influenced by the high amount of long chain ethyl ester originated from behenic acid (C22:0) that composes 57.2% of crambe oil. The rapeseed, soybean and jatropha curcas biodiesel that exhibit approximately the same amount of long chain ethyl ester showed calorific values near to ∆H= 39450 J g-1.

The use of biodiesel from Tilapia visceral oil will allow the development of economy where a fishery is developed. The fishing industry has resulted in the production of large quantities of fish waste, especially fish viscera which are discarded into the environment. The aim of this work is to show the process of Tilapia visceral oil extraction, characterization and obtainment of biodiesel by ethylic route. For the feasibility of transesterification is necessary that the oil has low moisture content and free fatty acids (FFA) below 5%, since the high value of these two parameters can preclude transesterification by forming high quantities of soap. The results of this study show that the Tilapia visceral oil has low moisture (0,12%) and only 3.11% of FFA. For the experiment it was used 1.8% of catalyst KOH, obtaining a high yield of biodiesel as shown by nuclear proton 1H NMR analysis. The results are very promising and show that it’s possible to convert a fish waste in biodiesel.

The calorific value indicates the energy available in the fuel. It is therefore an important parameter to compare the consumption of biodiesel compared to mineral diesel. Another important feature is the cetane number, which measures the ignition quality of diesel fuel. A high cetane number indicates that the fuel will ignite faster than those with a lower value of this parameter. This work aims to obtain experimentally and compare the cetane number and calorific value of different blends of biodiesel from Tilapia visceral oil with petroleum diesel (B5, B10, B15, B20 and B30). The results show that the B5 blend has the highest calorific value (∆H= 44488.0 J g-1) followed by B10 (∆H = 44275.0 J g-1), B15 (H = 44053.0 g J-1), B20 (∆H = 43829.0 J g-1) and B30 (∆H = 42895.0 g J-1). However, the B5 blend have the lowest cetane number (47.7% vol), followed by B10 blend (53.0 vol%), B15 (58.6 vol%), B20 (62.5 % vol) and B30 (73.1 % vol). The increase of the studied biodiesel in blends with petroleum diesel improves the ignition quality of these blends. However, it decreases the calorific value of this same fuel.

Published: May 2017

The current social impact of new transmission and distribution lines and the growth in environmental requirements has not lead to the expansion of the electric power grid but to the optimization of the existing assets. Flexible AC Transmissions Systems (FACTS), developed during the last decades of the past century, have become one of the most remarkable solutions for the optimization of the electrical power grid. Due to their flexibility, different types of FACTS have been proposed to solve similar transmission system operation problems. This paper reviews the FACTS devices used for solving these problems and the techniques used to optimize their location. The objective of the paper is to serve as a guide for selecting the right power system analysis and optimization technique for a given transmission system problem, and the most used FACTS for this purpose. The main operation issues that have been considered are: voltage control, assets optimization, line overloads and grid congestion, voltage stability problems, angle stability problems, contingencies and economic issues. In this study, the power system analysis and optimization methods have been divided into four main groups: classic optimization methods, technical criteria based methods, heuristic or meta-heuristic based methods and simulation based methods.

Published: May 2017

The role of indigenous and renewable energy resources is crucial for countries that want to be less dependent on foreign countries. Renewable energy resource power plants have many advantages when compared with other resources. They make countries less energy dependent and they also have environmentally friendly technologies when compared with other resources. Turkey is a country that has an abundance of renewable energy resources and biomass is one of the most promising energy resources in renewables. The goal of this paper is to determine Turkey’s electricity potential based on industrial wastes i.e. municipal solid waste (MSW) and urban wastewater treatment sludge potential, using applicable electricity generation methods. In this attempt, electrical energy potential of these resources has been found by using applicable waste to energy methods, technical and economical parameters. Electrical energy potential of Biogas (Landfill gas included) based on these resources is an amount of 6.73 billion kWh/year. Municipal solid waste (MSW) and dried municipal wastewater treatment sludge electrical energy potential is an amount of 23.81 billion kWh/year. Based on the resources stated; using the biogas and biomass energy values, calculations resulting in primary energy potentials; the installed capacity for gas-motor systems, gas turbine systems (Simple cycle), gas & steam turbine systems (combined) and boiler – steam turbine systems have been determined.

Published: May 2017

The objective of this paper is to show different models that simulate the behavior of a photovoltaic cell. The study of photovoltaic systems, in an effective way, requires a precise knowledge of the IV and PV characteristic curves of those photovoltaic elements. This paper shows the results of the implementation of various methods of simulation of a photovoltaic cell, the representation of their IV and PV characteristic curves. The knowledge of the curves allows to know the functioning of the cell and the adequacy of the model. The models are implemented in Matlab/Simulink and in Excel. To carry out mathematical models or experimental data will be needed.
A New, Ultra-Low-Cost Power Quality and Energy Measurement Technology Bringing SmartGrid on the Factory and Automation Floor
Authors: A. Alex McEachern  , B. Andreas Eberhard
Published: May 2017

This paper introduces a new application for Power Quality and Energy Monitoring: embedding power quality monitors inside sensitive industrial, commercial, automation, manufacturing and medical equipment – and bringing SmartGrid to the factory and automation floor. Using power quality monitors to solve intermittent problems has also been limited by the cost of monitors. In this case, the monitors are generally installed at the equipment terminals. So the monitors can either directly interface with the load, or they can interface via e-mail or WebServer with a remotely connected user. In addition the new technology also combines a high accuracy energy monitor that can precisely control loads based on the load profile. It also introduces IEC 61000-4-30 which is an excellent standard that ensures that all compliant power quality instruments, regardless of manufacturer, will produce the same results when connected to the same signal. However, instruments that comply with the Class A requirements of this standard have, until now, been too expensive for common use. Now a new set of technologies developed by an American company, in cooperation with a Japanese company, demonstrate that it is possible to manufacture three-phase power quality instruments that are fully compliant with the Class A requirements of IEC 61000-4-30, and to do so at ultra-low-cost, allowing these monitoring devices to be used even at entry levels of individual loads.

Published: May 2017

This paper presents a comparative analysis between a three-phase and a six-phase Permanent Magnet Synchronous Generators (PMSGs) used for small power wind turbines with battery storage. Both studied PMSGs are equipped with diode rectifiers connected across the stator windings terminals. The numerical results are obtained using a 2D Finite Element (FE) analysis of field-circuit coupling type and they emphasize the pros and cons of using three-phase or six-phase PMSGs. The performance analysis includes the evaluation of torque ripples, machine efficiency, voltage and current waveforms and their harmonic distortions, etc. A part of the numerical results are validated by experimental measurements.
New Approach to Assess Unbalance and Harmonic Distortion in Power Systems
Authors: Patricio Salmerón  , Alejandro Pérez  , Salvador P. Litrán
Published: May 2017

This paper presents a new decomposition of the apparent power for power systems in unbalance conditions and harmonic distortion at Std. 1459 framework. From the new terms of power defined, a set of appropriate indicators to assess the unbalance in terms of harmonic distortion are introduced. From here, we obtain the balanced and unbalanced components for each set of voltage and current harmonics. The process is carried out through the application of the FFT to the Park vectors of voltage and current. This allows to develop an efficient algorithm from the computational point of view.. The algorithm has been implemented in a virtual instrument for measurements of a practical case. The results obtained show the utility of the proposed approach to assess the unbalance in the presence of distortion.

Published: May 2017

A general model for an irreversible solar-driven Brayton multi-step heat engine is presented. The model incorporates a regenerator, an arbitrary number of turbines (Nt) and compressors (Nc) and the corresponding reheating and intercooling pro cesses; thus the solar-driven Ericsson cycle is a particular case where NtNc . For the so lar collector we assume linear heat losses and for the Brayton multi-step cycle irreversibilities arising from the non-ideal behavior of turbines and com pressors, pressure drops in the heat input and heat release, heat leakage through the plant to the sur roundings, and non-ideal couplings of the working uid with the external heat reservoirs. We obtain the collector temperatures at which maximum over all e ciency max is reached as a function of the thermal plant pressure ratio and a detailed com parison for several plant con gurations is given.
Adaptation, mise à l’épreuve et évaluation d’interventions
complexes en santé publique : lec¸ons tirées du Nurse-Family
Partnership dans le secteur de la santé publique au Canada

Published: May 2017

Introduction

Le Nurse-Family Partnership (NFP) est un programme de visites à domicile destiné aux nouvelles jeunes mères défavorisées sur le plan socioéconomique. Les données
issues de trois essais contrôlés randomisés (ECR) américains ont solidement démontré l’efficacité des interventions quant à l’amélioration de l’issue de la grossesse,
de la santé et du développement des enfants ainsi que de l’autonomie économique des mères. Cependant, l’efficacité du NFP dans le contexte canadien des services de santé et
des services sociaux, qui diffère de celui des États-Unis, reste à déterminer. Cet article vise à décrire le processus complexe suivi pour adapter la recherche sur le NFP et
mettre ainsi en oeuvre ce programme au Canada.

Méthodologie

L’évaluation menée au Canada se divise en trois étapes : 1) adaptation de l’intervention, 2) mise à l’épreuve de l’intervention dans des études de faisabilité et
d’acceptabilité à petite échelle et 3) réalisation d’un ECR et d’une évaluation du processus dans le cadre de l’étude intitulée British Columbia Healthy Connections
Project (BCHCP). Cette évaluation à grande échelle permettra d’enrichir la base de données probantes du NFP par la tenue d’une étude supplémentaire sur les mécanismes
biologiques susceptibles de témoigner de la relation entre l’intervention et les effets sur le comportement des enfants.

Résultats

L’adaptation de la documentation du NFP pour les visites à domicile est un processus continu. Un projet pilote a montré la faisabilité du recrutement des femmes
admissibles au NFP. Il a aussi révélé qu’il était préférable au Canada que le NFP soit mis en oeuvre par les organismes de santé publique et que les infirmières et infirmiers en
santé publique (ISP) s’occupent des interventions. Enfin, il a montré que ce programme intensif de visites à domicile a bénéficié d’une réception positive de la part des clientes,
des membres de leur famille et des fournisseurs de soins de santé. Les prochaines étapes – à savoir l’ECR et l’évaluation du processus – ont été entamées dans le cadre du
BCHCP. Ce projet jettera les bases d’une évaluation à long terme des principaux résultats en matière de santé publique concernant des familles hautement vulnérables.
A Possible-Worlds Solution to the Puzzle of Petitionary Prayer
Authors: Parker Ryan Matthew , Rettler Bradley
Published: May 2017

If the thing he prays for doesn’t happen, then that is one more proof that petitionary prayers don’t work; if it does happen, he will, of course, be able to see some of the physical causes which led up to it, and `therefore it would have happened anyway’, and thus a granted prayer becomes just as good a proof as a denied one that prayers are ineffective. -- CS Lewis, The Screwtape Letters
