Kadri Yürekli | Müberra Erdoğan | Ömer Faruk Karaca
The unnatural change in the globe under influence of devastating global warming has been quashing the overall functioning of ecosystem since industrial revolution. Thus, the human-induced disaster caused by proportional increase of greenhouse gases in the atmosphere has affected the normal functioning of hydrologic cycle. Under the undesirable condition, the amount of hydrologic variables began to diverge over time. Hydrologic variable should be homogeneous for the reliability of hydraulic structure while predicting necessary design criteria for its construction. Therefore, the test of whether this requirement is true should be performed in the context of any given hydrologic data’s homogeneity before being passed to the implementation of statistical approaches to the data. The study carried out in Yesilirmak basin was realized on homogeneity of seasonal maximum streamflow data from eight gauging stations operated by The General Directorate of State Hydraulic Works (DSI). Yesilirmak River basin area is approximately 5% of surface area of Turkey. Yesilirmak River is one of the major rivers of Turkey and its long is 519 kilometers. There are three main tributaries of the Yesilirmak River, named as Kelkit, Cekerek and Tersakan. Its water is mostly used for purposes as irrigation, drinking, fisheries and wildlife. The parametric and non-parametric procedures, called as standard normal homogeneity, Pettitt, Buishand range and von Neuman ratio were used for this reason. Statistically significant inhomogeneity with respect to the all of the statistic tests taken into account in the study was detected in the considered streamflow data sequences presented.

In this study, synergistic effects of secondary compounds on the total diet amount of consumption and biological properties of Uresiphita gilvata, which is a polyphagous species, were investigated. The biological properties of this species against different secondary compounds will provide important clues in the fight against species. For this purpose, nine diets were prepared by adding tannic acid, gallic acid and p-Coumaric acid at different concentrations (1, 3, 5%) in the control diet. With the addition of these secondary compounds to the diet at 3% concentration, a total of fourteen diets were prepared, three diets in double combination, and one diet in triple combination. Compared to the control group, it was found that increasing amounts of tannic acid and p-Coumaric acid in the diet resulted in a decrease in total dietary consumption and pupal protein amounts of U. gilvata larvae. It was found that the total consumption amount and pupal weight increased with the increase of gallic acid concentration in diets. The development time was prolonged by adding all three secondary compounds to the diet at increasing concentrations. In this study, it was observed that the larvae were resistant at the related concentrations and combinations of the secondary compounds used in this study and reached the pupae stage.

Nowadays, “energy production” and “global climate change and mitigation”, which are in direct relation with each other, are the most important environmental problems waiting for a solution. Renewable and sustainable energy sources provide the most appropriate alternatives for the solution of this problem. In Turkey, one of the important raw material potential of renewable and sustainable energy sources is “Biomass energy”; it is used in biogas production, biofuel production such as biodiesel, bioethanol, biobuthanol and gasification-burning technology. In this study; the potential for agricultural wastes derived from agricultural activities and domestic wastes from Çukurkuyu town of Niğde where the main economic source are agriculture and livestock, were calculated by using incineration technology, which is one of the methods of production of renewable electric energy. In this study, a feasibility study was carried out for the production of renewable electricity from the wastes generated in the town and the potential of renewable electricity generation was determined by the obtained data. Moreover, in this study, fossil fuel balance of the electricity produced from biomass was determined and potential for greenhouse gas emission reduction was determined. Thus, as an alternative to fossil fuels, energy production from renewable sources has been determined both in agricultural waste management.
