    Diverticular disease and posture during defecation : a prospective comparative study
    (Univ Catholique Louvain-Ucl, 2018) Ozturk, O.; Koklu, H.; Akbal, E.; Aksoy, E. K.; Altan, E.; Basar, O.; Yuksel, O.
    Background and study aims : Although several factors are thought to be responsible for the development of colonic diverticulosis the underlying pathogenesis is still obscure and needs clarification. The aim of this study was to determine the prevalence, location and clinical features of CD and especially to detect whether there is an association between CD and postures during defecation. Patients and methods : This prospective study enrolled 757 patients. The subjects were divided into two groups as a diverticulosis group (D group, n:95) and non-diverticulosis group (non-D group, n:662). Results : The median patient age was 54.9 +/- 13.2 years. CD frequency was 12.5% (n:95). The most commonly involved part of the colon was the sigmoid colon (56.8%). Diverticula location was on the left in 45.3% (n:43), on the right in 24.2% (n:23) and on both sides of the colon in 30.5% (n:29). Patients in the D group were older (p<0.001) and were predominantly female (p:0.04). The frequency of sitting during defecation (Western type toilet) was higher in the D group compared to the non-D group (72.2% vs 53.5%; p:0.007). The use-time of a Western-type toilet was longer in the D group compared to the non-D group (p:0.04). In multivariable logistic regression analysis, age and toilet type were independent risk factors for the development of diverticulosis. Conclusion : Sitting during defecation seems to increase the risk of CD.

    Effect of Waste Compost on Physical Properties in Xerofluvent Soils
    (Univ Namik Kemal, 2012) Yuksel, O.
    This two-year field study was conducted to investigate the effects of municipal sol id waste compost on physical properties in Xerofluvent soils. The waste compost used in the study was obtained from Uzundere Compost Factory belong to Municipal of Izmir City. The study was carried according to split block experimental design with three replications and seven compost doses (0, 2, 4, 8, 10, 12 and 16 t/da). The amount of compost applications to the plots was calculated based on dry compost weight. Winter barley was sown in the plots and grown without any fertilization until the harvest. After harvesting, the soil samples were taken and analyzed. In the second year, the winter barley was sown in the same plot without any waste compost and mineral fertilizer. At the end of harvest, again soil samples were taken and analyzed. In the soil samples taken, in both years, some physical properties such as aggregate stability, hydraulic conductivity, bulk density, saturation percentage, field capacity, wilting point, were determined. According to the results of analyzes, waste compost obtained from solid residuals had a positive effect on physical properties of soils. This effect was significant on hydraulic conductivity, bulk density, saturation percentage and field capacity whereas it was not significant on aggregate stability, and wilting point. In generally, at the higher compost doses, the effect of compost on the physical properties of the soils was found to be more significant.
