Öğe Characterization of a timed insemination (TAI) program in non-lactating Brown-Swiss cattle(BLACKWELL PUBLISHING, 2007) Kose, M.; Erdem, H.; Guzeloglu, A.; Dursun, S.; Tekeli, T.[Abstract not Available]Öğe Determination of heavy metal pollution in grass and soil of city centre green areas (Konya, Turkey)(HARD, 2007) Onder, S.; Dursun, S.; Gezgin, S.; Demirbas, A.This research was conducted to determine levels of heavy metal pollution in the years 2003-04. In this research, samples of grass and soil taken from green areas in 8 different areas of Konya city centre were used as material. The samples were obtained from factory gardens, areas experiencing heavy traffic and residential areas. The changes in analysis results of heavy metal levels (Pb, Cu, Zn, Co, Cr, V, Cd and Ni) in the samples were discussed for sampling years and sampling places in both grass and soil samples. The results of the study showed that heavy metal contents in both soil and grass samples were higher in 2004 than in 2003. In this study, some heavy metal content in the samples obtained in areas with heavy traffic and in factory garden areas was over the limit levels (5.67 ppm for Pb in soil and 10.69, 27.51 and 0.19 ppm for Cu, Cr and Cd in grass, respectively) and represents a risk for humans.Öğe Early pregnancy regulates genes of hyaluronan system in ovine endometrium(WILEY-BLACKWELL, 2016) Kiyma, Z.; Hitit, M.; Kose, M.; Kaya, M.

N.; Dursun, S.Konya Province has the largest agricultural lands among the other provinces in Turkey and thus it has been named "food store of Anatolia" as far as agricultural production is concerned. However, the climate around Konya Province is semi-arid and thus irrigation of the agricultural lands is not usually adequate. In other words, many towns around Konya have to draw waters, for irrigation, from lower quality sources including municipal wastewaters. With the application to land of large volumes of minimally pretreated wastewater, it is evident that considerable potential for adverse health effects exists. Microbiological pollution could occur from food crop contamination, pathogen-laden aerosols [2], ground water pollution or surface water pollution. A case study was carried out with the principal objective to investigate entrobacteria as an indicator of microbiological pollution in vegetables collected from public markets of three central towns in the province of Konya. The work was conducted upon 20 specimens representing 10 different varieties of vegetable samples taken from the main public markets of Konya city. The results were summarized as follows: (1) The distribution of total coliform bacteria on the vegetable specimens ranged from 12 to 50%. (2) The highest incidence of coliform bacterial pollution was found with parsley (approx. 100%) and it was followed by watercress, lettuce, radishes, green onions, carrots, cabbage, cucumber skin, tomatoes and green pepper (33-39%) specimens, respectively. (3) Among the markets from which the vegetable samples were collected, the highest incidence of the microbiological pollution in terms of the coliform distributions was detected with the Evil market and it was followed by the Beysehir and Doganhisar markets respectively. (4) The incidences of the pathogenic bacterial pollution found with the vegetable specimens were generally very low when compared to coliform bacterial distribution detected from the specimens, and the genera of the pathogenic bacteria isolated from the vegetables were as follows: Proteus sp., Salmonella sp. and Shigella sp. (5) The findings indicated that the presence of fecal pollution of the vegetables which were supposed to be eaten fresh in the region. (6) The "scalding" was found to be the most effective method to disinfect the vegetables studied among the four treatments tested then it was followed by the treatments of "washing with a bactericide" and "washing with a detergent" respectively [1-9].Öğe miRNAs expression during the peri-attachment period of pregnancy in the ovine endometrium(WILEY-BLACKWELL, 2016) Kose, M.; Ozel, C.; Guzeloglu, A.; Kaya, M.

Air quality modelling and indexes are used to introduce the information on local air quality indicators in polluted regions. Estimation and monitoring of air quality in the city centres are important due to environmental health and comfort of human-related topics. Air quality approximation is a complicate subject that artificial intelligent techniques are successfully used for modelling the complicated and nonlinear approximation problems. In present study, artificial neural network and an adaptive neuro-fuzzy logic method developed to approximate the impact of certain environmental conditions on air quality and sulphur dioxide pollution level and used with this study in Konya city centre. Data of sulphur dioxide concentrations were collected from 15 selected points of Konya city for prediction of air quality. Using air quality standards, air quality was discussed by considering the sulphur dioxide concentration as independent variables with meteorological parameters. Different meteorological parameters were used for investigation of pollution relation. One of the important modelling tools, adaptive network-based fuzzy inference system model, was used to assess performance by a number of checking data collected from different sampling stations in Konya. The outcomes of adaptive network-based fuzzy inference system model was evaluated by fuzzy quality charts and compared to the results obtained from Turkey and Environmental Protection Agency air quality standards. From the present results, fuzzy rule-based adaptive network-based fuzzy inference system model is a valuable tool prediction and assessment of air quality and tends to propagate accurate results.Öğe Oxidation Rate of Sulphite on Decomposing Leaf Litter(TUBITAK, 1998) Dursun, S.; Boddy, L.; Frankland, J. C.; Ineson, P.Sulphite (SO32-), the major solution product of SO2, has been shown to inhibit leaf litter decomposition at concentrations occurring in urban rainfall. The rate of oxidation of SO32- on leaf litter is a major factor in determining the effect of this inhibition and this study investigated the oxidation rate of SO32- to sulphate (SO42-) when applied to decomposing Scots pine (Pinus sylvestris L.) needle litter under laboratory conditions. Measurements showed that SO2 has a short life under atmospheric conditions and oxidises very quickly in the presence of metal ions and in alkaline conditions. After addition of sulphite (0.1 mM SO32-) to Scots pine litter, about 80% of the SO32- oxidised in 5 h, and SO32- was not detected after 24 h. The time period over which SO32- underwent oxidation at environmentally-realistic concentrations was sufficient to affect microbial decomposition processes in soil and leaf litter.Öğe Removal of trichloroethylene (TCE) in up flow anaerobic sludge blanket reactors (UASB)(DIAGNOSIS PRESS LTD, 2007) Ozdemir, C.; Dursun, S.; Karatas, M.; Sen, N.; Sahinkaya, S.Low concentrations of chlorinated aliphatic compounds may be found in wastewater and contaminated soils from different industrial sources and in the air arising from these sources. Low levels of Volatile Organic Compounds (VOC) can be removed by adsorption, incineration and biofiltration methods. These methods have some disadvantages, such as low removal efficiency or high operation costs. Chlorine has been removed from the chlorinated aliphatic compounds by anaerobic conditions. The aim of this research was the investigation of biological treatment of VOC,v in high flow speed reactors. The resistance capacity of micro-organisms was investigated in an upflow anaerobic sludge blanket reactor (UASB) with automated control system, by feeding with co-substrate additions, by loading by different ratios of organic matter varying hydraulic retention time (HRT), maintaining stable concentrations of COD and Volatile Fatty Acids (VFA), pH,alkalinity, temperature (35 degrees C) etc. during the anaerobic treatment. Glucose, sodium sulphate, calcium chloride, ammonium bicarbonate, potassium phosphate and methanol were used as the co-substrates. In these studies the removal rates of TCE were opproximately 86.4-90. 0 %. The decomposition ratios were calculated for TCE as 0,231 mg g(-1)VSS d(-1). The highest methane ratio in the obtained biogas was 67.8 %,for TCE. Also, inhibition concentrations (IC) in 24 hours were determined as IC50,(.)31. 1 and IC25,(.) 9.9.Öğe Removal of wastewater treatment sludge by incineration(CRC PRESS-TAYLOR & FRANCIS GROUP, 2018) Dursun, S.; Ayturan, Z. C.; Dinc, G.Incineration is one of the mostly used techniques for the disposal of solid wastes applied in more than 40 European countries. There are several methods used for this purpose such as fluidized bed and rotary kiln incinerators. Several types of wastes can be reduced with incineration techniques. Incineration is a significant option disposing wastewater treatment sludge. However, specific features of sludge should be considered. Most of the treatment sludge originating from municipal wastewater treatment plants includes 95-99% of water, pathogenic microorganisms, food and large amounts of organic matter. According to the content of sludge, residues and air emissions show some differences. In this study, mainly wastewater treatment sludge incineration options were investigated and compared with respect to their efficiencies and sustainability. Moreover, the end products and emissions after application of incineration options were explored and precautions or modifications that can be applied to the systems was offered.
