agriculture is a complex system science and the knowledge of it is consisting of much concepts and relationships. examinations in connection with site-specific farming have been carried out by our institute since 1998. precision farming is a way of agricultural production, which takes into account the in-field variability, a technology where the application-seeding, nutrient replacement, sprayi...

BACKGROUND Rising dementia prevalence rates rise combined with the policy objective of enabling people with dementia to remain living at home, means that there will be a growing demand for dementia care in the community setting. However, GPs are challenged by dementia care and have identified it as an area in which further training is needed. Previous studies of GPs dementia care educational ne...

BACKGROUND General Practitioners {GP} in Sweden prescribe more than 50% of all prescriptions. Scientific knowledge on the opinions of GPs regarding drug information has been sparse. Such knowledge could be valuable when designing evidence-based drug information to GPs. GPs' opinions on public- and industry-provided drug information are presented in this article. METHODS A cross-sectional stud...

For engineering applications high precision GPS with survey grade receivers allows positioning in real-time to a centimetre level of precision. Many of the error sources affecting the GPS signal have been significantly removed in order to achieve such high precision. However, one error source that is difficult to mitigate is that of the multipath error. GPS signal multipath occurs when the GPS ...

The GPS antenna is the connecting component between the GPS satellite and the GPS receiver. Its function is to transfer the satellite signal propagation to the receiver with minimum interruption. A satisfactory process is expected to result in an accurate and reliable performance of the GPS receiver. Multipath error is a dominant error source connected with GPS positioning. Mitigation of such e...

BACKGROUND Vagal nerve stimulation (VNS) has been shown to provide a protective effect against ischemia/reperfusion (I/R)-related arrhythmias by preventing the loss of Connexin43 (Cx43). Our previous studies showed that atrial epicardial ganglionated plexus stimulation (GPS) might exert a VNS-like effect on ventricular electrophysiology. OBJECTIVES To investigate whether GPS could preserve Cx...

We present a new approach to remote sensing of water vapor based on the global positioning system (GPS). Geodesists and geophysicists have devised methods for estimating the extent to which signals propagating from GPS satellites to ground-based GPS receivers are delayed by atmospheric water vapor. This delay is parameterized in terms of a time-varying zenith wet delay (ZWD) which is retrieved ...
