However, this article presents evidence that the scope conditions have improved, based on document analysis and semi-structured interviews with actors involved in the implementation process. Four main factors are considered. First, the Commission’s monitoring capacities benefit from an improved access to data sources other than those provided by the member states, and from a reduced legislative agenda, allowing for a more intense focus on implementation. Second, subnational actors have improved their implementation capacity through knowledge transfers and strategic planning, facilitated by improved statistical data. Third, inspection networks benefitted from technical advances, such as the access to satellite images, presenting new opportunities for the detection of environmental crimes, and new software programs facilitating risk-based inspections. Finally, citizens’ and non-governmental organizations’ improved access to justice in environmental matters contributes to a stricter enforcement of EU law.</p> <p>&nbsp;</p> <p>Keywords: networks; European Union; software programs</p> 2018-05-25T00:00:00+01:00 ##submission.copyrightStatement## https://www.sproc.org/ojs/index.php/wjer/article/view/3945 Driving cycle and temperature effects on the energy performance of a solar-powered electric vehicle in Istanbul 2019-01-12T11:12:33+00:00 Erim Gurer erim.gurer@metu.edu.tr Onur Taylan erim.gurer@metu.edu.tr Tugce Yuksel erim.gurer@metu.edu.tr <p>The global warming and climate change problem can be solved by emitting less greenhouse gases by transportation. Switching from fossil fuel burning cars to electric vehicle cars is one of the most promising solutions, however; they are as clean as their energy source. In this study, a generic model to estimate energy generation from PV-covered parking lot system and energy demand from electrical cars is established, and Istanbul is selected for a case study. Two main effects are investigated in the demand side: i) ambient temperature and; ii) driving style. In this study, it is considered that a 150 m2 parking lot for 10 cars is covered with 90 PV modules, size of 22.5 kW, to charge EVs in Istanbul, Turkey. The results show that the total annual energy consumption can be covered by a grid-connected PV system. Additionally, an off-grid PV system can cover about 198 and 268 days of energy demand in a year for the urban and highway driving conditions, respectively. Overall, ambient and driving conditions can affect the energy demand by 40%–60%.</p> <p>&nbsp;</p> <p>Keywords: Driving cycles, electric vehicle, solar charging, temperature effect.</p> 2018-05-25T00:00:00+01:00 ##submission.copyrightStatement## https://www.sproc.org/ojs/index.php/wjer/article/view/3946 Theoretical study to calculate the vibration modes of a wind turbine blade with a new composite material 2019-01-12T11:12:32+00:00 Rabie ElAlaoui elalaoui.rabie@gmail.com Hamid Mounirv elalaoui.rabie@gmail.com Boudi El Mostapha elalaoui.rabie@gmail.com Abdellatif El Marjani elalaoui.rabie@gmail.com <p>A precise understanding of the dynamics of a blade is essential for its design, especially in the development of new structures and the resolution of noise and vibration problems. This understanding involves the study of experimental and/or theoretical modal analysis. These latter present effective tools for describing, understanding and modelling the dynamic aspect of each structure, in the present work, we are going to establish the Eigen-mode of a wind turbine blade made by a new composite material ‘hemp fibre’ using theoretical calculation for flap-wise, edge-wise and torsional mode using the finite element method applied to a structure consisting of a beam embedded at one end, based on the Euler-Bernoulli hypothesis and the equation of beam’s motion. Furthermore; we compare the obtained results with those of composite material made by fibreglass.</p> <p>&nbsp;</p> <p>Keywords: Blade, Eigen-mode, hemp fibre, flap-wise, edge-wise, torsional, fibreglass.</p> 2018-05-25T00:00:00+01:00 ##submission.copyrightStatement## https://www.sproc.org/ojs/index.php/wjer/article/view/3947 Investigation of modal analysis of new materials for wind turbine blade 2019-01-12T11:12:30+00:00 Rabie ElAlaoui elalaoui.rabie@gmail.com Hamid Mounir elalaoui.rabie@gmail.com Boudi Elmostapha elalaoui.rabie@gmail.com Abdellatif Elmarjani elalaoui.rabie@gmail.com <p>The aim of this study is the search for new material for the manufacture of wind turbine blades in order to improve its performance and to reduce its cost. A composite material based on hemp natural fibres is studied. A numerical simulation using the finite element method is developed and a comparison of the performances of the new material with the usual composite of carbon fibres and glass is performed. The simulation allows us to calculate the proper values and the Eigenmodes of a wind turbine blade in the rotation. The results showed that the epoxy matrix allows to reduce the weight of composite hemp/epoxy relative to other matrix. It is almost 4.6% lighter than hemp/phenolic and 1.9% that hemp/polyester, so the blades hemp/epoxy has several advantages over the blades hemp/phenolic or over the blades hemp/polyester: this new material is characterised by lower weight and lower cost and has better mechanical features.</p> <p>&nbsp;</p> <p>Keywords: Eigenmode, proper values, new material, blade, rotation.</p> 2018-05-26T00:00:00+01:00 ##submission.copyrightStatement## https://www.sproc.org/ojs/index.php/wjer/article/view/3486 Effects of human activities on water quality assessment of Ala River in Akure, Ondo State, Nigeria 2019-01-12T11:12:35+00:00 Samuel Dare Fagbayide fsamueldare@gmail.com Francis Olawale Abulude waleabul@outlook.com <p>The purpose of the study was to assess the water quality parameters of Ala River found in Akure, Ondo State, Southwest, Nigeria. The river is considered one of the most important irrigation and drinking water resources in Akure, Nigeria. Three locations were chosen spatially along the watercourse to reflect a consideration of all possible human activities that are capable of affecting the quality of the river water. The water samples were collected monthly for three consecutive months (February to April 2015) at the three sampling sites. The water samples collected were analyzed for physicochemical parameters which include pH, total dissolved solids, dissolved oxygen, biochemical oxygen demand, total hardness, phosphate,&nbsp; temperature,&nbsp; calcium, magnesium, chlorine, nitrate, iron and zinc using standard methods and their environmental effects on the river were investigated. There were variations in the quality of the sampled water when compared with the World Health Organization (WHO) standards for domestic and commercial water for the selected parameters. The traces of some hazardous physical and chemical impurities in the river were above the acceptable limits, and thereby pose a health risk to several rural communities who rely heavily on the river primarily as their source of domestic water. Therefore, the law should be enforced to discourage unnecessary waste dumping and discharging of another form of pollutants into surface water in Nigeria.</p> 2018-05-25T00:00:00+01:00 ##submission.copyrightStatement##
