    The Future of Fossil and Alternative Fuels Used in Automotive Industry
    (Institute of Electrical and Electronics Engineers Inc., 2019) Dogan B.; Erol D.
    Fossil fuels, which has determined all the important economic and political events of the last century, are the most widely used fuel type in the world. Petroleum or crude oil is a fossil fuel. In this study, the amount of petroleum reserves in the world and their lifetime are examined. Based on the studies conducted by international oil companies and independent energy organizations, it is predicted that oil reserves will be depleted in about 50 years. Paris Agreement aims to reduce fossil fuels and oil use in order to reduce air pollution by 2030. Until the 2050s, it is seen that many developed countries conduct studies on how to meet their energy needs for the areas such as electricity, heat and transportation 100% by renewable energy sources. Oil directly effects the economies of all countries in the world. In this study, oil production and consumption rates and alternative fuels that will be used in future vehicles are examined. In the upcoming years, economic growth, policy and technology will be shaped by alternative fuels. In addition, it has been determined that alternative fuel studies to replace oil have not reached the desired level yet. © 2019 IEEE.

    Pulmonary and extrapulmonary tuberculosis CCL1 in patients with rs159294 T/A gene Polymorphysm
    (2013) Özdemir F.A.; Erol D.; Yyüce H.; Konar V.; Kara Şenli E.; Bulut F.; Deveci F.
    Investigation of CCL1 rs159294 T/A gene polymorphism in pulmonary and extrapulmonary tuberculosis patients Introduction: The purpose of this study is to reveal whether CCL1 rs159294 T/A polymorphism in pulmonary and extra-pulmonary tuberculosis patients pose a risk to catch tuberculosis or not. Materials and Methods: In the study, peripheral blood samples from the control group, which includes 160 patients, who consulted to Fırat University Faculty of Medicine, Pulmonology Policlinic in Elazığ province and who were diagnosed with tuberculosis; and 160 healthy individuals, were taken and put into tubes containing EDTA. Each tube contained 2 cc blood samples. DNA isolation was made from these blood samples and CCL1 rs159294 T/A polymorphism was defined with PCR-RFLP analysis. Results: For CCL1 rs159294 T/A polymorphism, TT genotype was found in 98 (61.3%) patients, TA genotype was found in 58 (36.3%) patients, AA genotype was found in 4 (2.5%) patients among 160 patients with tuberculosis; and TT genotype was found in 50 (70.4%) patients, TA genotype in 20 (28.2%) patients, AA genotype was found in 1 (1.4%) patient among 71 patients with pulmonary tuberculosis; TT genotype was found in 48 (53.9%) patients TA genotype was found in 38 (42.7%) patients and AA genotype was found in 3 (3.4%) patients among 89 extrapulmonary tuberculosis patients. And in control group, among 160 healthy individuals, TT genotype was found in 100 (62.5%) individuals, TA genotype was found in 58 (36.3%) individuals, AA genotype was found in 2 (1.3%) individuals and no statistically significant difference was found. Conclusion: CCL1 rs159294 T/A polymorphism do not form an inclination to tuberculosis in our population.

    Simplification of laparoscopic extraperitoneal colposuspension: Results of two-port technique
    (2000) Batislam E.; Germiyanoğlu C.; Erol D.
    Purpose: The aims of the present prospective study were to apply a new simplification for Laparoscopic Burch Colposuspension and to assess the postoperative results of this treatment modality for stress urinary incontinence. Materials and methods: Twenty-four patients underwent simplified laparoscopic procedure via two ports, utilising endoscopic tacker and two stripes of prolene mesh. Patients were evaluated for operative time, duration of urethral catheter, length of hospital stay, complications and continence status. Results: The technique was successful in 21 patients after 24 months follow-up. Average operative time was 39 minutes. The lengths of urethral catheterisation and hospital stay were 22 and 45 hours, respectively. One operative complication and three postoperative recurrences were recorded. Conclusion: Laparoscopic bladder neck suspension continues to develop as the instruments and techniques are improved. In carefully evaluated patients, it provides safe and minimally invasive procedure. We report the results of a new technique to simplify and speed up a laparoscopic extraperitoneal colposuspension.
