International Journal of Environmental Pollution and Environmental Modelling <p>IJEPEM (International Journal of Environmental Pollution and Environmental Modelling) is a leading journal for environmental researchers in several areas such as water pollution, wastewater pollution, air pollution, solid waste management, biotechnology, soil pollution, surface and groundwater, renewable energy, energy management, microbiology, sustainability, waste recovery and transformation, fuzzy logic, artificial neural networks.</p> Yasin Akin Ayturan en-US International Journal of Environmental Pollution and Environmental Modelling 2618-6128 An Investigation on The Reduction and Management of Medical Solid Wastes <p>During the activities of hospitals, medical waste is generated as a natural result of the process. Although medical wastes are produced as a result of activities to improve health quality, they have a high risk of health problems if they are not managed appropriately. More and more importance are given to medical waste management in terms of health risks in the world and in our country and academic studies are carried out in terms of the most appropriate disposal methods. Disposal methods in addition to the superiority of appropriate methods in eliminating health risks, disposal costs also require multidisciplinary management in order to impose financial burden on health institutions. University hospitals need management because of the environmental impacts they generate due to high rates of waste generation. The most important environmental risks arising from health institutions are medical and hazardous waste management problems. Wastes from university hospitals are grouped in terms of their nature and capability. Domestic wastes, packaging wastes, medical wastes, hazardous wastes, radioactive wastes, wastewater containing high concentrations of tissue and body fluids are produced from health institutions. Wastes from university hospitals are subject to waste management applied in other health institutions in that they are the same in character as wastes from health institutions. It is better to supervise and implement the management of wastes from university hospitals. Because large amounts of waste are produced, the results are more traceable and more appropriate in terms of results. In this study, besides the reduction of hospital-generated wastes, the studies carried out for the evaluation and the studies that can be done were evaluated.</p> Sukru Dursun Copyright (c) 2020 International Journal of Environmental Pollution and Environmental Modelling 2019-07-03 2019-07-03 3 1 1 14 Air Pollution Controlled Prototype Modelling of Electrostatic Precipitator for Small Scale Industries <p>Electrostatic precipitator (ESP) is efficient pollution control equipment. This paper aims in designing of a low cost and portable ESP for small scale industries for controlling the pollution. A prototype of two stage ESP is developed with low cost, less weight and easily available materials. Which can be used in boilers, hospitals and cooking purposes. A pollution test is conducted on the prototype for verifying SO<sub>2</sub> and CO<sub>2</sub> emission by installing this ESP and verified.</p> Rajkumar. G. Yasin Akın Ayturan S.

As is well known, Rock mass classification systems (RMR, SMR,GSI, Q, CSMR..etc), can be used to assess rock slope stability, hence, this paper intended to employing SMR classification, to prove that a rigorous rock mass classification will give more reliable if uncertain parameters are dropped and considered indirectly. The present study was carried out of 14 rock cuts in which 3 different causes of instability (Planer, Wedge, Toppling) along Hadim – Gevne dam segment of the Konya –Alanya roadway,this road distingueshed with existence of different lithological units. However, the cut slopes are located within recrystallized limestone, hard to extremely hard and highly jointed. In order to determine engineering geological properties of the rocks exposed along the roadway, then assess stability of the cut slopes, fourteen cut slopes were detailed identified. During field investigation all field observations/measurements parameters were recorded, which involved a detailed discontinuity surveys discontinuity conditions, geometrical relationship between slope and rock discontinuities (dips angles and slope), slope excavation methods; and underground water condition. Based on the field observations, stability analyses of the cut slopes and SMR values concluded that the slopes can be categorized into partially stable (50%), unstable (30%) and completely unstable (20%) with probable planar failure mode (20%), toppling failure mode (27%) and wedge failure mode (53%) . To ensure slope stability of road cuts against failure, flattening with different angles, sometimes constructing rock block walls may also be adopted beneficially.</p> Ahmed Ibraheem Mohamed Ali Ferhat Bayram Copyright (c) 2020 International Journal of Environmental Pollution and Environmental Modelling 2019-07-03 2019-07-03 3 1 22 26 Nutrients and Cucurbita Eaten from The Seed <p>The importance of nutritional support is increasing in determining the effectiveness of some nutrients used in nutrition or herbal products that are considered medically important in the prevention and treatment of diseases, providing consumer awareness and protecting our health. In this review, firstly information is given about pumpkin species and seeds eaten; the amount of these products in terms of nutritional support and living organisms. Pumpkin, seed, oil, seeds and wastes were evaluated with a different perspective.</p> Şerife Biçer Bayram Eda Güneş Copyright (c) 2020 International Journal of Environmental Pollution and Environmental Modelling 2019-07-03 2019-07-03 3 1 27 33 Implementation of 480W LLC Resonant Converter <p>This study presents the design of an LLC resonant converter as using the leakage inductance of the transformer instead of the inductance in the resonance tank. With serial resonant characteristics, the power MOSFETs are conducted at zero voltage switching and secondary diodes are commutating under soft switching, so the switching power losses on the semiconductor components are decreased. Using the proposed power stage and feedback control loop design considerations, the LLC resonant converter can achieve high power conversion efficiency and stability enhancement. This study provides the working principle of the resonant LLC converter topology by designing the simulation model.</p> Yunus Emre Bulut Mertcan Aşçı Burak Akın Copyright (c) 2020 International Journal of Environmental Pollution and Environmental Modelling 2019-07-03 2019-07-03 3 1 34 40
