    A case of acute hemorrhagic cystitis caused by salmonella paratyphi a in a pediatric patient
    (2012) Yula E.; Deveci O.; Toka-Ozer T.; Tekin A.; Inci M.; Karakus A.
    It is a very rare medical condition that Urinary tract infection (UTI) caused by Salmonella species. Seven-year-old boy admitted to our hospital with complaint of lower abdominal pain, burning and pain during urination (dysuria), nausea and increased fever. The patient had normal vital signs but abdominal examination revealed bilateral suprapubic tenderness. In the laboratory, it was found the amount of hemoglobin 12.9 g/dL, red blood cell count 4.8 million/mm3, white blood cell count 11.800/mm3, platelet count 275.000/mm3, level of C-reactive protein 30.2 mg/L, serologically S. paratyphi A "O" antibody (1/160) and S. paratyphi A "H" antibody (1/320) positivity. Urine examination showed gross hematuria and leukocyte esterase was positive. Urine culture was performed and isolate obtained urine culture was identified with conventional methods. Result of urine culture was reported as Salmonella species and isolate was determined as Salmonella paratyphi A by using anti-sera during the advanced identification. Results of radiological imaging were found normal. The patient was diagnosed as acute hemorrhagic cystitis caused by S. paratyphi A and received ceftriaxone treatment for seven days and had a full recovery. We conclude that in case of acute hemorrhagic cystitis, S. paratyphi A should be considered as causative agent in endemic areas.

    Energy saving by prediction of the optimum cutting rate in stone cutting process: An industrial scale study
    (2012) Karakus A.; Ceylanoglu A.; Gul Y.
    Sawing of rocks cost is controlled to a large extend by the cutting rate which is influenced by the properties of the saw and the sawn rock. Energy consumption is very important unit cost parameter, which strongly depends on cutting rate, in stone cutting process. In this study, in order to find the optimum cutting rate for Karacadag basalt units, primarily the properties of the basalts from four different regions were determined. After that, cutting experiments were carried out in three stages on four types of basalt units in a marble cutting plant with a special saw that is only used for cutting basalt. Based on specific energy, optimum cutting conditions were determined. It was found that the optimum cutting rate changes depending on the rock unit, cutting depth and the saw diameter. Optimum cutting rate, cutting depth, saw diameter and rock properties were evaluated using multiple regression analysis and models were developed. It was concluded that the optimum cutting rate can reliably be estimated using one of the developed models which were included cutting depth, saw diameter; and some rock properties, such as uniaxial compressive strength, Young's module, cohesion, Poisson's ratio and Schmidt hardness. © Sila Science.
