    Solar energy production and economic evaluation are analyzed, in this study, by using daily solar radiation and average temperature data which are measured for 3 years in the Osmaniye province in Turkey. Besides, this study utilizes the photovoltaic- (PV-) based grid connected to a power plant which has an installed capacity of 1 MW investment in electricity production. Economic values show that the net present value (NPV), the first economic method in the research, is about 111941 USD, which is greater than zero. Therefore, the payback year of this investment is approximately 8.3. The second one of these methods, the payback period of the simple payback period (PBP), is 6.27 years. The last method, which is the mean value of the internal rate of return (IRR), is 10.36%. The results of this study show that Osmaniye is a considerable region for the PV investment in electricity production. As a result, investment of a PV system in Osmaniye can be applicable

    Entropy Generation for Nonisothermal Fluid Flow: Variable Thermal Conductivity and Viscosity Case

    No full text
    This paper investigates the entropy generation of a nonisothermal, incompressible Newtonian fluid flowing under the effect of a constant pressure gradient in plane Poiseuille flow. The effects of variable viscosity and thermal conductivity are also included. The viscosity and thermal conductivity of the fluid exhibit linear temperature dependence and the effect of viscous heating is included in the analysis. Channel walls are kept at constant temperatures. Velocity, temperature, and entropy generation profiles due to heat transfer and fluid friction are plotted. The effects of Brinkman number, Peclet number, pressure gradient, viscosity, and thermal conductivity constant on velocity, temperature, and entropy generation number are discussed. Discretization is performed using a pseudospectral technique based on Chebyshev polynomial expansions. The resulting nonlinear, coupled boundary value problem is solved iteratively using Chebyshev-pseudospectral method

    1st International Mediterranean Science and Engineering Congress (IMSEC) -- OCT 26-28, 2016 -- Adana, TURKEYWOS: 000412033800078Disposal of waste tires is one of the most important problems that should be solved. This problem can be solved by considering waste tires for production of hydrogen or fuel for diesel engines. This paper presents the studies on the performance and emission characteristics of a four stroke, four cylinders, naturally aspirated, direct-injected diesel engine running with various blends of waste tire pyrolysis oil (WTPO) with diesel fuel. Fuel properties, engine performance, and exhaust emissions of WTPO and its blends were analyzed and compared with those of petroleum diesel fuel. The experimental results showed that WTPO diesel blends indicated similar performance with diesel fuel in terms of torque and power output of the test engine. It was found that the blends of pyrolysis oil of waste tire WTP010 can efficiently be used in diesel engines without any engine modifications. (C) 2017 Hydrogen Energy Publications LLC.

    WOS: 000229458600013The effects of Malathion, an organophosphate insecticide, on the egg production and hatchability of the adult females of Pimpla turionellae L (Hymenoptera: Ichneumonidae) reared on pupae of the wax moth Galleria mellonella L were investigated. The hatchability ratio of eggs, which are left in the host during the life cycle of P. turionellae, have became less at all concentrations (1.000, 0.100, 0.010 and 0.001 ppm). It is remarkable that the highest reduction in egg production appeared between days 25 and 40 with an average of 43% at a concentration of 0.100 ppm. A concentration of 0.010 ppm increased the egg production with an average of 14% between days 10 and 40

    The effects of a meridic diet on the sex ratio of offspring, on glycogen and protein content, and on productivity and longevity of adult Pimpla turionellae L. (Hymenoptera: Ichneumonidae) for five generations

    In this study, we determined the effects of a meridic diet on adult emergence, glycogen and protein level of the endoparasitoid Pimpla turionellae, and investigated female lifetime, adult emergence rate, egg numbers and hatching for five generations. The meridic and control diets were fed to P. turionellae for 28 days. The meridic diet was associated with a significant increase in the total adult emergence, which reached 93.33% on day 16; 100% females were produced from eggs laid on day 25. The meridic diet significantly decreased glycogen level in P. turionellae on days 13 and 16, while it significantly increased the protein level on days 13, 16 and 19 in comparison to the control natural diet. The meridic diet did not negatively affect total adult emergence, lifetime and egg numbers over the first and second generations when compared to the control. However, female lifetime and egg numbers were significantly decreased in F3, F4 and F5 generations. This manuscript is the first to report rearing the adult stages of P. turionellae on meridic diets for five generations. It shows that a chemically-defined meridic diet may be beneficial in improving the biological and biochemical fitness of the first couple of generations of these parasitoids reared for use in biological control programs
