BACKGROUND AND PURPOSE Patients with non-small cell lung cancer (NSCLC) often have inhomogeneous lung perfusion. Radiotherapy planning computed tomography (CT) scans have been accurately co-registered with lung perfusion single photon emission computed tomography (SPECT) scans to design radiotherapy treatments which limit dose to healthy 'perfused' lung. PATIENTS AND METHODS Patients with loc...
An antimicrobial-surface kinetic test which maximizes probability of cell-to-surface contact has been developed. The measurement of rate of kill by a nonleaching antimicrobial surface is based on the number of surviving bacterial cells at specific times of exposure to various amounts of total treated surface area of test substrate. This method gives information for direct comparison of rate of ...
Fluctuations in economic activity over the course of the business cycle imply signifi cant welfare costs. Most obvious are the costs associated with periods of relatively weak activity, when productive resources are under-utilised, and consumption is below par.1 Periods of relatively strong activity can also be costly since they imply an ineffi cient bunching of activity, consumption and invest...
A study was conducted in the Shandong province in North China to investigate the effects of different planting patterns on water potential characteristics of soil-plant-atmosphere continuum (SPAC) and yield of summer maize. Three planting patterns were applied, i.e. bed planting (BE), furrow planting (FU) and flat planting (FL). The results showed that although soil moisture content in 0–20 cm ...
