The most important constraint to potato production in the UK is the damage caused by the potato cyst nematodes (PCN) Globodera pallida and Globodera rostochiensis. These are serious pests, capable of causing substantial yield loss. Modern management systems depend heavily on nematicides which, at c. £360 ha−1 for granular and c. £550 ha−1 for fumigant(More)
A computer simulation of stereotactic breast biopsy was developed that paralleled the geometric configuration of a currently available breast biopsy system. This model was developed to define and improve the targeting of breast lesions with stereotactic biopsy techniques. Lesions must be clearly identified and accurately targeted on both views for(More)
Mechanical ventilation, through overdistension of the lung, induces substantial inflammation that is thought to increase mortality among critically ill patients. The mechanotransduction processes involved in converting lung distension into inflammation during this ventilator-induced lung injury (VILI) remain unclear, although many cell types have been shown(More)
A quadrature modulator operating from 250-1000 MHz, having a maximum output level of +3 dBm into a 50-ohm load and a noise floor of -155 dBm/Hz has been developed. The device draws 65 mA from a single 2.7 to 5.5 V supply when active, and 70 uA during standby. The high dynamic range achieved by this device is attributable to the design of its baseband(More)
Several archival studies of eyewitness identification have been conducted, but the results have been inconsistent and contradictory. We identify some avoidable pitfalls that have been present in previous analyses, and we present new data in which we address these pitfalls. We explored associations among various estimator variables and lineup outcomes for(More)
