AN EVALUATION OF CLASSROOM-ILLUMINATION: A CRITICAL-REQUIREMENT FOR EFFECTIVE DESIGNING AND CONSTRUCTION OF NATURALLY-ILLUMINATED SCHOOLS IN NIGERIA
by Osagie IBHADODE, Oluseyi Olarenwaju AJAYI, Abiodun Ayodeji ABIOYE, Joseph ISMAILA
Abstract: In this research paper, an attempt was made to experimentally investigate the indoor lighting-levels (illuminances) of one hundred and eighty (180) classrooms in sixty (60) public [primary and secondary] schools located in all six (6) geopolitical zones of Nigeria, from October 2012 September 2015. Consequently, twelve (12) field-studies were periodically carried-out to determine the indoor illuminances of all 180 classrooms under three (3) different sky-conditions [Clear', Partly-clear' and Overcast'] using the Hagner digital lux-meter model EC1'. The empirical data of classroom illumination-levels obtained under different sky-conditions were collated, tabulated, graphically illustrated and analyzed. From the research findings, while the Mean Indoor illuminance for tasks on desks' tops near Windows exposed to direct Sunlight and/or higher illumination () ranged from , the Mean Indoor illuminance for tasks on desks tops near Windows exposed to indirect Sunlight and/or lower illumination () ranged from , the Mean Indoor illuminance for tasks on desks tops at Center of Classroom () ranged from , and then, the Mean Indoor illuminance for tasks on boards () ranged from . Thus, based on the global standard values recommended by the CIE-ISO, IESNA, and EN, for minimal and optimal lighting-levels for classroom-activities like reading on the blackboard (= 500lux) and writing, drawing & reading etc., on the desks (= 300lux) in educational environments; it is evidently clear that the illumination-levels in majority of all investigated classrooms in the selected Nigerian schools swing to either extreme of being excessively higher or incredibly lower than the above-recommended levels. Furthermore, the Sign Test' analyses showed that the four alternative hypotheses , , and are statistically-significant and should be acceptedas a clear indication of the dangers of excessive solar irradiation and/or hazardously inadequate illumination in the classrooms of the investigated public [primary and secondary] schools in Nigeria. Hence, it is recommended that the Nigerian government should urgently address these issues by adopting the understated remedial/control measures.

Sustainable technologies in tourist accommodation;A qualitative review
by Angeliki N. Menegaki, George Agiomirgianakis
Abstract: Comprising all the aspects of the hotel sustainable technologies in a single state of the art paper is something missing from up-to-date tourist literature. Information on the subject is fragmented in various articles, web resources and the records of relevant tourism institutions and organizations. Sustainability in a hotel, besides its financial status which lies beyond the scope of this paper, comprises both environmental, social and technological data. The purpose of this paper is to review the sustainable featuresrnof the Greek hotels from a qualitative point of view. Due to space considerations, the quantitative point of view will become available in another paper that succeeds the current one. The reason we focus on Greek hotels is the importance of tourism for the Greek economy. It is envisaged that this review would help, first, hoteliers providing them with a benchmark in their businesses and an ideal sustainable reference point and second it may also help policy makers to obtain a qualitative overview of hotel sustainability in Greece and thus equip them with knowledge in designing policy measures aiming at the promotion and improvement of sustainability in Greek hotels. rn

The tribological potential of graphene growth from solid waste
by Mat Tahir Noor Ayuma, Abdollah Mohd Fadzli Bin, Tamaldin Noreffendy, Amiruddin Hilmi, Mohamad Zin Mohd Rody Bin, Tokoroyama Takayuki, Umehara Noritsugu
Abstract: This study aimed to identify the tribological potential of graphene growth from solid waste products on 99% copper (Cu) substrate via the Chemical Vapour Deposition (CVD) method. The study focused on graphene growth employing two types of solid waste sources; fruit cover plastic waste and oil palm fibre. The coated surface was examined using Scanning Electron Microscopy embedded with Energy Dispersive X-Ray Spectroscopy (SEM-EDS) and Raman Spectroscopy. The coated surface was tested in a Ball-on-Disc tester to determine its tribological properties, and the hardness test was performed using a Nano-indenter test machine on both the worn and unworn surfaces. From the peak findings obtained from the Raman spectrum analysis, graphene was successfully grown from both sources. However, the oil palm fibre produced higher carbon content compared to the fruit cover plastic waste. Meanwhile, the tribological study found that both coatings showed a higher coefficient of friction compared to pure copper. However, the wear rate was contradicted by the coefficient of friction where the wear rates were found to be 60% and 75% lower for Fruit Cover Plastic Waste (FCPW) and Oil Palm Fibre (OPF), respectively. Finally, the hardness analysis revealed that the coating was damaged at 100 m sliding as the surface hardness increased.

Management of material and product circularity potential as an approach to operationalise circular economy
by Tetiana Shevchenko, Jakub Kronenberg
Abstract: To make the general action plan more specific, a circular economy must introduce obligations for producers to use recycled materials. The present study suggests not only to restrict manufacturers access to use primary resources for certain products, but also to establish the only possible access to the material of a particular turnover, thereby creating demand for these or other outputs and maximising the number of uses of the same material. This article focuses on the development of a new approach for the operationalisation of a circular economy based on the management of material and product circularity potential by the following phases: (1) allocation of the explicit available potential, (2) fullest use of materials, and (3) building-up of new circularity potential for specific material and product in combination. In particular, the allocation of the explicit available potential reflects the aspect of restricting access to primary resources for manufacturers of certain products. The findings presented and discussed in this article provide a theoretical basis for the development of new metrics for measuring progress towards zero-waste and circular economy aimed at identifying and monitoring all the possible forms of the circularity potential such as opportunities, reserves, available resources, rather than the available resources only which were primarily considered in the past attempts at the operationalisation of circular economy.

Improving the performance and emission of CI engine using bio-fuel (botricoccus)
by Kuberan Jayaraman, N.ALAGUMURTHI Alagumurthi
Abstract: In this modern world the technology is developing day by day and hence the demand on fossil fuels and power keeps on increasing. Since the demand is very high, it is impossible to power up the entire world using petrol and diesel. The depletion of fossil fuels and the worst impact on environmental pollution have led to the search for renewable clean energies. Micro algae are presently the favourable source of biofuels for the substitution of fossil fuels. The micro algae oil is used as the bio fuel in the direct injection (DI) diesel engine. There are different species of micro algae among which the bio-oil extracted from the botricoccus sp algae has high lipid content, this is possible by using pyrolysis method. The 90% diesel is blended with 10% Botricoccus algae oil and the test was carried out to analyze the effect of diesel-biofuel on the engine performance, emission and properties such as specific fuel consumption, Brake thermal efficiency, Calorific value, CO, NOx, and HC. The experiment was conducted on a single cylinder four stroke diesel engine with diesel and bio-fuel blend at varying loads. The performance and emission results of the blended bio- fuel and diesel were compared, and the performance results, shows the bio-fuel blend is almost closer to the diesel, and the bio-fuel gives less emission than the diesel

Improvement in Wind Energy Production through Condition Monitoring of Wind Turbine Blades Using Vibration Signatures and ARMA Features: A Data-Driven Approach
by Joshuva A, Sugumaran Vaithiyanathan
Abstract: The main objective of this study is to improve the wind energy productivity by implementing the condition monitoring technique for wind turbine blades through vibration source. The fault detection and the isolation of the fault which affects the wind energy productivity were carried using machine learning algorithms. In this study, a three bladed horizontal axis wind turbine was chosen and the faults like blade bend, blade cracks, hub-blade loose connection, blade erosion and pitch angle twist were considered as these are the faults which affect the turbine blade. Initially, vibration sources were collected from the wind turbine using piezoelectric accelerometer and from that vibration source; needed features are extracted using ARMA through MATLAB. From the extracted feature, the dominating feature is selected using J48 decision tree algorithm and with the selected features, fault classification has been carried out. The fault classifications were carried out using Bayesian, Function and Lazy classifiers.

by Sugumaran Vaithiyanathan, Joshuva A
Abstract: The modern developments in wind turbine fault diagnosis and condition monitoring are urged in recent times. This paper aims to identify different types of faults which occur on wind turbine blade as they are prone to vibration stress due to environmental and weather condition. The fault diagnosis problem was carried out using machine learning approach. This study was carried out using vibration sources which has been acquired from good and other fault condition blades using data acquisition system. From the recorded signals, histogram features were extracted and classified using Meta classifiers. From the classifiers, a better data-model is suggested for a multi-class problem in wind turbine blade fault diagnosis.

by L. Saravana Kumar, B.R. Ramesh Bapu, R. Prakash
Abstract: In todays world, the applications of diesel engines are gradually increased in the area of agricultural and especially in commercial vehicle sectors. The present scenario emphasizes necessarily for the development of better techniques to improve the efficiency of the diesel engine and also the adverse effect of fossil fuels on the environment. The alternate solutions to avoid such problem, use of biofuel for diesel engines, which can be derived from plant oils. Biofuel has shown a promising alternative to fossil fuels and the application of newer technology for the production of biodiesel is highly related to energy demands. The purpose of this work is to investigate the consequence of biodiesel blends with diesel on exhaust gas temperature and emission characteristics. The exhaust gas temperatures were measured for the various loads for the given blends to measure the NOx emissions. In this work, the exhaust emissions and exhaust gas temperatures were measured in a 4 stroke, single cylinder, and constant speed diesel engine fueled with Calophyllum Inophyllum Methyl Ester (CIME) and its blends with diesel. The different blends such as B20, B40, B60, B80 of CIME blends with diesel and B100 (CIME) and diesel (100%) were used for this test run. The test results of different blends were compared with diesel fuel and presented in this paper.

Performance, emission and combustion analysis of diesel engine fuelled with emulsified biodiesel
by Radha Krishna Gopidesi, S.R. Premkartikkumar
Abstract: The present investigation is mainly focused on the reduction of NOX emissions from the diesel engine. In this experimental work, the diesel engine has initially run by diesel alone, secondly, 10% cottonseed methyl ester biodiesel (B10) and finally emulsion of 10% water with B10 (WiB10E) in combination. The emulsified biodiesel WiB10E shows the maximum reduction of NOX emissions in comparison with the pure diesel and B10 fuel operations. Also, due to the cooling effect provided by the water in the combustion chamber, the WiB10E shows the slight increase of the HC and CO emissions. Since WiB10E fuel has a boiling point difference, it leads to secondary atomisation. The WiB10E has shown the higher cylinder pressure of 65.92 bars at a crank angle of 366° due to microexplosion. Hence, emulsified biodiesel fuel is efficient in the reduction of NOX emissions amongst all the techniques.

3D Image Reconstruction from its 2D Projection A Simulation Study
by Hawraa Al-waelly, Hameed Abduljabbar
Abstract: A simulation study of using 2D tomography to reconstruction a 3D object is presented. The 2D Radon transform is used to create a 2D projection for each slice of the 3D object at different heights. The 2D Back-Projection and the Fourier Slice Theorem methods are used to reconstruction each 2D projection slice of the 3D object. The results showed the ability of the Fourier Slice Theorem method to reconstruct the general shape of the body with its internal structure, unlike the 2D Radon method, which was able to reconstruct the general shape of the body only because of the blurring artifact, Beside that the Fourier Slice Theorem could not remove all blurring artifact, therefore, this research, suggested the threshold technique to eliminate the excessive points due to the blurring artifact.

by Alyaa Abdulrazzak, Mohammad Haider
Abstract: LiNiCoO2 (LCNO) has been prepared using Combustion method with urea as the igniter and glycerol as the binding material due to its high activity. Urea, used as fertilizer, can be produced by way of sequence chemical approaches by means of the usage of H2, N2 and CO2.It is good performance hydrogen and carbon dioxide as storage medium due to high energy density (16.9 M*J *L−1, 10.1 weight percent of H2) for direct urea fuel cell (DUFC). Nitrates of Li+,Co+2 and Ni+2 had been combined together to shape a homogenous medium . Re- quired quantities of urea and glycerol have been brought to combination and made good a paste. This paste are heated to 400◦C for 2 h. The as-synthesized fabric used to be subjected to thermo- gravimetric (TGA) analysis to decide the top of the line varies of annealing temperatures. This mixtures were headed at (800, and 900) ˚C for 2 h in an air and various in the structural, morphological properties were studied. The structural of (LCNO) as powder had been studied with the aid of potential of X-ray diffraction and Scanning Electron Microscopy. From the structure analysis suggests that all the powders are crystallized in the layered shape (R - 3m). The product bought was once subjected to infrared bands of solids are normally assigned to vibration of ions in the crystal lattice FTIR of LCNO pure section was once recorded vary of (3500-500) cm*-1. The particle size of the nano particles was estimated with results during post annealing and the average sizes of the LiNiCoO2 structure is found to be (62-75) nm from SEM measurement. LiNiCoO2 is used as nano-batteries (storage energy) to prevent smoke from cars and vehicles that have a negative impact on the sustainability of the environment.

Preparation and study of a superconducting composite based on superconducting ceramic system
by Abdul Hameed Al –Sarraf
Abstract: Heat pollution could be through decreasing the electrical resistance of wire conductors. The main approach of this research is to modify the superconducting ceramic Y-Ba-Ca-Cu-(Hg, Ag)-O system.The composite samples consisting of YBa2Ca2Cu2.8(Ag,Hg)0.2 O7-δ superconductor ceramic and epoxy have been prepared. The stander four probe techniques and contactless induction based on Meissner effect were used to study the superconducting properties of sintered ceramic Y-Ba-Ca-Cu-(Hg,Ag)-O system and composite samples. The results showed that in all composite samples which were prepared by the addition of the ceramic superconducting powder as filler to the epoxy polymer ,there was no decrease in the Tc of ceramic superconductor YBa2Ca2Cu2.8Ag, Hg)0.2O7-δ precursor filler; a very slight change was observed. The superconductive nature is very sensitive to microstructure, represented by the porosity, density, grain size and consequently the granular specific surface area. The partial replacement of Cu ion by either Ag and Hg ions was found to modify the superconductive nature. And, the ability of mercury ion to play an important role as an oxygen donor is due to its high free energy of oxide formation compared to that of copper ion. Also, the advantage of using composite material is providing a high efficiency and low loss, which have not impeded the development of its applications.
