Over the past fifty years the development of high-tech farming has led to excessive amounts of fertiliser being applied to soil. Some research aspects of this abuse are described in relation to the uptake of nitrate into vegetables. In order to monitor this problem a high precision HPLC method capable of rapid throughput has been evolved. Using this HPLC(More)
Despite being commonly affected by degenerative disorders, there are few data on normal thoracic intervertebral disc dimensions. A morphometric analysis of adult thoracic intervertebral discs was, therefore, undertaken. Archival computed tomography scans of 128 recently deceased individuals (70 males, 58 females, 20–79 years) with no known spinal pathology(More)
In a typical pulsed THz system, the source is triggered by a fast laser pulse, and the detector is triggered by a delayed part of the same laser pulse. The time delay of detection is controlled by reflecting the second laser pulse at a mirror with precisely controlled movement. It is therefore possible to make accurate measurements of small time delays in(More)
