    Dehydration kinetics of howlite, ulexite, and tunellite using thermogravimetric data
    (Elsevier, 1999) Erdogan Y.; Zeybek A.; Şahin A.; Demirbaş A.
    In this study, some boron mineral samples (howlite, ulexite and tunellite) have been analysed by DTA and TG methods. The thermochemical reactions of these boron compounds have been studied. The dehydration kinetic parameters for howlite, ulexite and tunellite were activation energies: 65.0, 39.5 and 50.4 kJ mol-1; the pre-exponential factors: 50.8×105, 6.60×105, 32.4×105 s-1 and rate constants: 70.1, 113.1 and 82.3 s-1, respectively, at a constant heating rate of 10 K min-1. The average particle size was 200 μm for all samples. The order of dehydration reactions (n) was accepted as first order.

    Knowledge and views of students of the Celal Bayar University Manisa School of Health towards organ donation; [Celal Bayar Üniversitesi Manisa Saǧlik Yüksekokulu öǧrencilerinin organ baǧişina i̇lişkin bilgi ve görüşleri]
    (Turkiye Klinikleri, 2008) Özmen D.; Çetinkaya A.Ç.; Sarizeybek B.; Zeybek A.
    Objective: The study was carried out to investigate the knowledge and opinions on organ donation of students in the Celal Bayar University School of Health (Department of Nursing, Midwifery and Health Official). Material and Methods: The sample of this descriptive study consisted of all students enrolled in the school (n= 394) and 75.1% of the students (n= 296) were present at the school on the day of filling out the questionnaire which included 25 items. Data were collected between January and February 2006 by face-to-face interview. SPSS 10.0 for Windows was used for the analysis of the data. Results: The mean age of the students was 20.87 ± 1.7 and 72.3% were females. Overall, 66.9% stated that they were not informed on organ donation and 36.1% were willing to donate their organs. The major reasons for organ donation were "to serve humanity" (82.2%) and "conscience satisfaction" (41.2%). In addition, 51.7% of the students indicated that religion allowed organ donation. Statistical analysis was carried out by chi-square analysis. Female students and the students with relatives and close friends who had donated their organs were more willing to donate their organs compared to other groups. Conclusion: The results of this study suggested that training of health care professionals on organ donation was essential. Copyright © 2008 by Türkiye Klinikleri.
