After a long career in studying agricultural and rural development, in the following paper I take the opportunity to reflect on these issues in the rear view mirror. The advantage of this is of course that my biographical time span now covers a considerable historical one, starting with the apocalyptic alarms over the population bomb at the end of the 60s, especially in Asia, and the widespread fe
Self-recognition is a trait presumed to be associated with high levels of cognition and something previously considered to be exclusive to humans and possibly apes. The most common test of self-recognition is the mark/mirror test of whether an animal can understand that it sees its own reflection in a mirror. The usual design is that an animal is marked with a colour spot somewhere on the body whe
Complex-valued dynamics can be used for modeling rotationally invariant two-input two-output systems and bandpass systems when they are considered in the baseband. In a few instances, control design has been done in the complex domain, which facilitated analysis and synthesis. While previous work has been application specific, we will discuss more generally how complex valued dynamics arise, basic
Two-dimensional electron gases with strong spin-orbit coupling covered by a superconducting layer offer a flexible and potentially scalable platform for Majorana networks. We predict Majorana bound states (MBSs) to appear for experimentally achievable parameters and realistic gate potentials in two designs: either underneath a narrow stripe of a superconducting layer (S stripes) or where a narrow
AIMS AND OBJECTIVES: To conduct a survey of the clinical nursing practice in European countries in accordance with the European Stroke Strategies (ESS) 2006, and to examine to what extent the ESS have been implemented in stroke care nursing in Europe.BACKGROUND: Stroke is a leading cause of death and disability globally. Optimal organisation of interdisciplinary stroke care is expected to ameliora
Wildfires pose a significant risk to human livelihoods and are a substantial health hazard due to emissions of toxic smoke. Previous studies have shown that climate change, increasing atmospheric CO2, and human demographic dynamics can lead to substantially altered wildfire risk in the future, with fire activity increasing in some regions and decreasing in others. The present study re-examines the
A new simplifed formula is derived for the absorption cross section of small dielectric ellipsoidal particles embedded in lossy media. The new expression leads directly to a closed form solution for the optimal conjugate match with respect to the surrounding medium, i.e. the optimal permittivity of the ellipsoidal particle that maximizes the absorption at any given frequency. This defnes the optim
Background: Choroid plexus (CP) supports the entry of monocyte-derived macrophages (MDMs) to the central nervous system in animal models of traumatic brain injury, spinal cord injury, and Alzheimer's disease. Whether the CP is involved in the recruitment of MDMs to the injured brain after ischemic stroke is unknown. Methods: Adult male C57BL/6 mice were subjected to focal cortical ischemia by perm
We will in this paper present methods and algorithms for estimating two-view geometry based on an orthographic camera model. We use a previously neglected nonlinear criterion on rigidity to estimate the calibrated essential matrix. We give efficient algorithms for estimating it minimally (using only three point correspondences), in a least squares sense (using four or more point correspondences),
While the concepts of planning and scheduling seem to be adequately discussed in the project management literature, relatively few examples of factors specifically affecting the performance of planning and scheduling are to be found. The study reported in this paper investigated a set of factors identified as enablers and barriers to successful project planning and scheduling of construction proje
The literature during 2000–2016 about drying of biofuels from the forest has been reviewed. Biofuels constitute a low-cost energy resource that is likely to continue to increase and the dryers for such products should be simple, robust, and easy to operate. In 1970s and 1980s, rotary dryers and flash dryers were the most common types, and in 1990s, superheated steam (SHS) dryers became common. Mai
