Safety and security are key aspects for the success of tourism in every destination. Rather than objective risks, it is rather the tourist's individual and subjective perception of these risks that mostly infl uence destination choice and in the long run tourism fl ows from one country to another. Th e concept of risk perception has been highly studied in tourism, however the literature remains...

Stakeholders' perceptions towards tourism development within destinations have been emphasized by researchers and practitioners. However, literature has only focused local residents' role in tourism development, leaving a gap in knowledge on stakeholders' engagement in tourism development process. Th is study investigates stakeholders' perceptions, attitudes and involvement in tourism developme...

The project aims to explore two fractal models (by Lowen and Liebovitch) of ion channel kinetics, and how this affects spike train patterns. The project also intends to extend the Liebovitch model and explore how fractal dimension affects potassium ion channel conductance profiles, and the behavior and rate of action potentials. 1 I n t r o d u c t i o n Fractal patterns have been used to model...

objective: different categories are available for estimating of radiation dose. radioisotopes with the same energy and almost the same physical properties have similar effects. monte carlo technique is a computerized method based on mathematical simulation of physical processes. the main purpose of this study is to show that beta particles are not able to penetrate deep into the water. also dif...

In this study, we fabricated a Cerenkov fiber-optic dosimeter (CFOD) without any scintillator to measure Cerenkov radiation signals owing to gamma-rays. The relative depth dose (RDD) distributions of Ir-192 HDR brachytherapy source were obtained by using the CFOD based on a subtraction method and the RDD curve was compared with the simulation result of Monte Carlo N-particle extended transport ...
