The research reported in this paper on the changes in absorbance and the calibration of a proposed UVA (320-400 nm) dosimeter have established the phenothiazine-mylar combination as a potential UVA dosimeter for population studies of UVA exposures. The change in optical absorbance at 370 nm was employed to quantify the UVA exposures. This change starts to saturate at a change in absorbance of a...

Introduction: A study was performed to evaluate radiation dose distribution and dose gradient around cylindrical applicators for high-dose-rate (HDR) brachytherapy systems with 192Ir, 60Co brachytherapy source applied for rectal and vaginal cancers treatments.   Materials and Methods: Two additional computed tomography (CT) based plans were generated using a ...

Because of their unique optical and stimuli-response properties, polydiacetylene-based platforms have been explored as an alternative to complex mechanical and electrical sensing systems. We linked chromic responsive polydiacetylene (PDA) onto a peptide-based molecular recognition element for trinitrotoluene (TNT) molecules in order to provide a system capable of responding to the presence of a...

the study was consequently investigated effect of different tanning methods on apparent density, thickness, tensile strength and also extension percentage in three different tanning (chromic, alum and vegetable) of grown part of ostrich skins (n = 15; 12 to 14 months). average apparent density and thickness of leathers were 0.7 ± 0.0gr/cm2 and 1.7 ± 0.1 mm, respectively. the breaking load, tens...

BACKGROUND AND OBJECTIVES A significant number of women experience perineal trauma following vaginal deliveries and they require stitches. This may result in perineal pain, dyspareunia and faulty healing. The type of suture material which is used, will influence these factors. This study was conducted to compare the impact of two absorbable suture materials which were used for episiotomy repair...

Commercial zeolites with CHA, MFI, and LTL framework topology are subjected to acid treatment chromic (H2CrO4) solutions concentrations ranging between 0.1 10 w/%. As forms polymeric species as a function of concentration, specific effects obtained these three zeolites, differing by their topology, pore size, Si/Al ratios crystal size. The etched characterized X-ray diffraction, SEM, TEM, N2 ph...

  Introduction: Patients administered with a therapeutic dose of 131I for thyroid cancer treatment are potential sources of unacceptably high radiation exposure to other individuals, particularly the patient's immediate family members. The aim of this study is to investigate effects of early liothyronine consumption after radio-iodine therapy on accumulated dose and e...
