TL;DR: In this article, the effects of the Richardson number (between 0.01 and 100), Hartmann number, angular rotational velocity of the cylinder (between −50 and 50), inclination angle of the magnetic field, and the power-law index (within 0.6 and 1.4) on the fluid flow and heat transfer characteristics are numerically investigated.

TL;DR: It was showed that UAE of lycopene requires less time, lower temperature and lower solvent than COSE, and was determined that the most efficient application for COSE was extracting samples by 50:1 solvent solid ratio at 60 °C for 40 min run.
Abstract: Tomato paste processing wastes, an important by-product of the paste industry, is rich in potentially health-promoting compounds such as lycopene. In this study, extraction yield of lycopene from tomato paste processing wastes by application of ultrasound assisted extraction (UAE) was compared with conventional organic solvent extraction (COSE) method. BHT (butylated hydroxytoluene) 0.05 % (w/v) added hexane:acetone:ethanol (2:1:1) mixture was used as solvent. Three different solvent solid ratios; 50:1, 35:1 and 20:1, (v/w) were used in both COSE and UAE. COSE experiments were performed at 20 °C, 40 °C and 60 °C for 10, 20, 30 and 40 min. 50, 65 and 90 W of ultrasonic power were applied in UAE for 1, 2, 5, 10, 15, 20 and 30 min. Lycopene contents of the samples were determined by spectrophotometric method. The effects of different factors, including the temperature, solvent solid ratio and ultrasonic power on lycopene yield were investigated. It was determined that the most efficient application for COSE was extracting samples by 50:1 solvent solid ratio at 60 °C for 40 min run, for UAE, 35:1 (v/w) solvent solid ratio, 90 W ultrasonic power for 30 min run. It was showed that UAE of lycopene requires less time, lower temperature and lower solvent than COSE.

TL;DR: Enuresis is an important problem for both families and children in Turkey for which specific guidelines should be developed and specific methods have been tried in the treatment of enuresis.
Abstract: There has been limited epidemiological research about nocturnal enuresis in Turkey. The objectives of this study were to ascertain the prevalence of nocturnal enuresis and the epidemiological factors associated with this in Turkish children aged 7-11 y, living in Manisa. Included in the study were 2000 children from various primary schools in Manisa. Parents were asked to fill out our specially designed questionnaire. In all, questionnaires for 1703 children were completed and returned to the department (871F, 51.1%; 832M, 48.9%). The prevalence of nocturnal enuresis for females was 10.6%, for males it was 16.9% and the overall prevalence was 13.7%. The prevalence of nocturnal enuresis decreased with age. Enuresis nocturna was found to be more common in children with a family history of bedwetting (76.5%). Deep sleeping, poor toilet habits and low educational level of the family were associated with enuresis. Consanguineous marriage did not influence the incidence of enuresis nocturna. There was no difference between enuretics and nonenuretics with reference to breastfeeding, being firstborn or being right- or left-handed. In our opinion, enuresis is an important problem for both families and children in Turkey for which specific guidelines should be developed. Various methods have been tried in the treatment of enuresis because of its multi-factorial aetiology. Child, family and physician co-operating together achieve the best help to both child and family.

TL;DR: The aim of this study was to determine the change in antimicrobial susceptibility of Escherichia coli isolates from patients with community-acquired urinary tract infection (UTI) for the years 1998 through 2003 and to suggest that the current empirical antibiotic therapy used for these patients is inappropriate.
Abstract: Urinary tract infections are among the most common infections with an increasing resistance to antimicrobials. The aim of this study was to determine the change in antimicrobial susceptibility of Escherichia coli isolates from patients with community-acquired urinary tract infection (UTI) for the years 1998 through 2003 and to suggest that the current empirical antibiotic therapy used for these patients is inappropriate. During the study period, 7,335 community urine samples of which 1,203 (16.4%) grew bacterial isolates were analyzed. Among the total of 1,203 isolates, 880 (73.2%) were E. coli. The range of resistance of E. coli to ampicillin was 47.8 to 64.6% and that to trimethoprim-sulfamethoxazole was 37.1 to 44.6% during the study period. The susceptibility pattern of E. coli to nitrofurantoin and cefuroxime did not vary significantly over the 6-year period. There was a significant increase in the susceptibility of E. coli to ciprofloxacin (11.3 - 26.7%), amoxicillin-clavulanate (18.4 - 29.2%) and gentamicin (7.0 - 25.6%) (P < 0.05). Empirical initial treatment with ampicillin and trimethoprim-sulfamethoxazole was thus inadequate in approximately half of UTI cases in our region.
