Modelling solar irradiance on a slope under a leafless deciduous forest

Rowland, James D. January 1989 (has links)
This thesis investigates variations in solar irradiance incident upon sloping surfaces under deciduous forest in winter. A model is presented for prediction of solar irradiance at the surface which accounts for slope inclination and orientation, surrounding topography, isotropic absorption of solar radiation by the crown space, and shadows cast by the stem space. / Field data from two sites of different slope and aspect attest to the validity of the model; errors, based on 20-minute averages of instantaneous values, are 15.5% (RMSE) and $-$1.9% (MBE). Error is partially due to reliance upon global radiation measurements above canopy at a different site (partially cloudy conditions) and sampling error (sunny sky conditions). The variability of solar irradiance at the surface, and in the error of predicted values, is found to vary with sky condition, solar zenith and incidence angles, and slope orientation. However, integration to hourly and/or daily time periods improves model performance significantly.

Pain assessment : the role of the radiation therapist

Kyei, Kofi Adesi January 2010 (has links)
Thesis (MTech (Radiography))--Cape Peninsula University of Technology, 2010. / The focus of this study is the role of the Radiation Therapist (RTT) in the assessment of pain in cancer patients. The study was carried out at a Radiotherapy Department of a large Teaching Hospital in Ghana and addressed the following research questions; 1) What is the role of the RTT in the assessment of pain in cancer patients, 2) Why should the RTTs’ role be extended to include pain assessment, 3) What are the challenges for the RTT when taking on the role of pain assessment in radiation oncology and 4) How can pain assessment become a routine role for the RTT in a busy radiation oncology department? 5) How would this extended role of the RTT assist management of patient? This study was conducted because many cancer patients suffer pain and to many, it can be more debilitating than the primary disease itself. The RTTs who are involved in the daily management of cancer patients during their radiation treatment can find it stressful to witness their patients going through such pain particularly when they do not have a role in the management of pain. In Ghana, there are few radiation oncologists (ROs) and therefore an extended scope for RTTs, that includes pain assessment and a meaningful contribution to the management of their patients’ pain, would be advantageous to all. A mixed method research approach was adopted for gathering quantitative and qualitative data. This included data collection of; interview, observation and review of existing document. A pain questionnaire SF-MPQ-2 by Melzack (2009) was adapted as a tool for assessing pain in the study participants.
