Data for two years were respectively used in the study to represent... Continue here

3-dimensional Simulation Of Light Transport In Tissue Using A Steady State Monte Carlo Method For Photodynamic Therapy Application
Photodynamic therapy (PDT) is a developing treatment modality for cancer and surface carcinomas that uses a combination of non-ionizing light in the presence of a photosensitizing (PS) agent and oxygen to produce singlet oxygen that can be combined with other physiological factors to cause an organ cells death of the target area. This research simulates the... Continue here

The Use Of Semi-markov Model To Determine The Efficacy Of Cdc Staging Criterion In Nigeria (a Case Study Of General Hospital Minna, Niger State)
Semi-Markov model in discrete state and time to study the trajection among the various defined HIV/AIDs stages has been presented in this paper. The model was used to determine the staging of HIV- infected clients reported at heart-to-heart clinic of General Hospital Minna, Niger State, Nigeria for a period of 10 years. The result shows that there is no transition... Continue here

Dependence Of Raindrop Size And Shape Parameters On Rain Attenuation Prediction Over A Tropical Location
Rain attenuation is a phenomenon that weakens signal propagation, particularly in high frequency bands and in areas with significant rainfall rates, one of which is the tropical area. Falling raindrops undergo changes in shapes as they grow in sizes. The goal of this research is to use a theoretical method to examine the impact of drop shapes and sizes on rain... Continue here
