Publication Energy and emission benefits of chicken manure biogas production: A case study(Springer, 2021-03-01) Ulusoy, Yahya; Ulukardeşler, Ayşe Hilal; Arslan, Rıdvan; Tekin, Yücel; ULUSOY, YAHYA; ULUKARDEŞLER, AYŞE HİLAL; ARSLAN, RİDVAN; TEKİN, YÜCEL; Bursa Uludağ Üniversitesi/Teknik Bilimler Meslek Yüksekokulu; 0000-0003-2658-3905; 0000-0002-0111-6879; 0000-0003-3665-7680; 0000-0001-6563-5785; J-3560-2012; V-1754-2018; AAH-9267-2019; AAG-6056-2021Studies on the production of biogas of different organic materials in an anaerobic environment are being carried out all over the world. The most important parameters in these researches can be listed as raw material potential, production processes, economic analyses, and environmental effects. Chicken manure is one of the raw materials used in biogas production. In this study, in addition to the analysis of biogas and energy production potential from chicken manure, greenhouse gas emissions were analyzed to evaluate environmental effects. In Turkey, chicken manure is not adequately processed and causes environmental pollution. The model biogas plant and potential energy generation were researched in this field study. The pilot plant produces 8.58 million m(3) of biogas per year by processing about 110 thousand tons of waste. It produces 17 GWh/year of electricity and 16 GWh/year of thermal energy, as well as reducing CO2 greenhouse gas emissions by 13.86 thousand tons/year.Publication A modular training project for vocational education and improvement in Turkey(Sage Publications Ltd, 2009-04-01) ARSLAN, RİDVAN; TEKİN, YÜCEL; Yazıcı, Murat; YAZICI, MURAT; Kuş, Abdil; KUŞ, ABDİL; Kaynak, Z. Gökay; Bursa Uludağ Üniversitesi/Ziraat Fakültesi; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi; 0000-0002-0111-6879; 0000-0002-8720-7594; J-3560-2012; M-4741-2017; V-1754-2018; AAG-9412-2021Various vocational training methods, most of which overlap with lifelong learning programmes, are being used to address the problem of unemployment - an issue of vital importance, especially for developing countries. This article examines the introduction of a modular certification project in Turkey supported by EU training funds. The objective of the project is to enable people who are unemployed to find work and people in employment to improve their professional skills and competences, and therefore their opportunities. The researchers observed the employment status and development of the 245 people who received a certificate. They found that 89% either had found work in a sector consistent with their training, thanks to their participation in the project, or had to taken up a different position in their current field of employment.Publication Energy and emission benefits of chicken manure biogas production: A case study(Springer Heidelberg, 2021-03-01) Ulusoy, Yahya; ULUSOY, YAHYA; Ulukardeşler, Ayşe Hilal; ULUKARDEŞLER, AYŞE HİLAL; Arslan, Rıdvan; ARSLAN, RİDVAN; Tekin, Yücel; TEKİN, YÜCEL; Bursa Uludağ Üniversitesi/Teknik Bilimler Meslek Yüksekokulu.; 0000-0003-2658-3905; 0000-0002-0111-6879; AAH-9267-2019; J-3560-2012; V-1754-2018Studies on the production of biogas of different organic materials in an anaerobic environment are being carried out all over the world.

Five levels of moisture content ranging from 7.28 to 17.77% d.b. (dry basis) were used. The average length, width, thickness, arithmetic and geometric mean diameters, sphericity, thousand grain mass and angle of repose ranged from 5.145 to 6.199 mm, 3.760 to 4.474 mm, 3.537 to 4.223 mm, 4.147 to 4.965 mm, 4.090 to 4.893 mm, 0.795 to 0.789, 52.3 to 64.6 g, and 25.87 to 29.38 degrees as the moisture content increased from 7.28 to 17.77% d.b., respectively. The bulk density was found to be decreased from 821.3 to 745.2 kg/m(3), whereas the grain volume, true density, porosity, terminal velocity, and projected area were found to be increased from 27.88 to 47.33 mm3, 1230.0 to 1456.7 kg/m(3), 30.43 to 46.57%, 4.86 to 5.29 m/s, and 17.48 to 19.26 mm(2), respectively. There is a 43% increase in surface area from grain moisture content of 7.28 to 17.77% d.b. The static coefficient of friction on various surfaces increased linearly with the increase in moisture content. The rubber as a surface for sliding offered the maximum friction followed by galvanised iron, medium density fibreboard, stainless steel, aluminium and glass sheet. As moisture content increased from 7.28 to 17.77%, the rupture forces values ranged from 67.39 to 39.44 N; 63.86 to 42.18 N, and 53.96 to 41.79 N for thickness (Z axis), length (Y-axis) and width (X-axis), respectively.
