The emission of the airborne particles from epoxy resin test sticks with different CNT loadings and two commercial products were characterized while sanding with three grit sizes and three disc sander speeds. The total number concentrations, respirable mass concentrations, and particle size number/mass distributions of the emitted particles were measured using a condensation particle counter, a...

Break a ruler of length n inches with indentations at each inchmark into n sticks of length one by repeatedly picking up all the fragments which are still of length greater than one and throwing them down all at once until all the sticks are of length one. Assume that each stick breaks into exactly two sticks uniformly at the inchmarks. What is the expected number of throws needed to complete t...

THIS Oration is given annually to welcome students to the Hospital. In the past, students spent the first two years of study at the University and often wondered when they would ever see a patient. Then they came to hospital and were welcomed at the annual oration. With the new curriculum, students have been in hospital already, but the welcome is no less genuine. I am going to address my remar...

icrotubule (MT) assembly is a dynamic process involving the addition and removal of tubulin ␣␤ heterodimers. The binding of microtubule-associated proteins (MAPs) to MTs helps to prevent depolymerization M of assembled filaments. Despite years of study, there has been little consensus on the structural basis for this stabilization. Open a number of textbooks on the subject, and you are likely t...

OBJECTIVES Many studies have reported that olfactory dysfunction frequently occurs in chronic rhinosinusitis (CRS) populations; however, the prevalence and degree of olfactory loss has not been systematically studied. The aims of this study were to use combined data to report the prevalence of olfactory dysfunction and to calculate weighted averages of olfactory test scores in CRS patients. D...

The study aimed to determine the effects of Salvadora persica L. sticks on oral bacteria and odor in comparison to traditional mouth disinfection with mouth rinses. Thirty-five healthy fasting volunteers took part in a crossover clinical trial involving the application of Listerine Cool Mint mouth rinse by the traditional panoral rinsing method or a site-specific method targeting the subgingiva...

The cross-cultural adaptation and validation of the Sniffin`Sticks test for the Portuguese population is described. Over 270 people participated in four experiments. In Experiment 1, 67 participants rated the familiarity of presented odors and seven descriptors of the original test were adapted to a Portuguese context. In Experiment 2, the Portuguese version of Sniffin`Sticks test was administe...
