Major threats to biodiversity and ecosystem persistence are fragmentation of habitats and declining population sizes. For conservation biologists to understand the consequences of declining populations for the long term persistence and recovery of species worldwide, it is important to know and understand the underlying causes of potential threats, such as the depletion of genetic diversity, which
This paper presents an inductorless ultra-low power frontend for applications such as sensor networks and medical implants. By using a completely inductorless topology the chip area is just 0.017mm2, excluding pads. A real input impedance of 300Ω is achieved with current feedback. Manufactured in 65nm CMOS, it measures more than 17dB gain from 100MHz to 2000MHz while consuming only 175μW from a 0.
We find effective, or homogenized, material parameters for Maxwell’s equations when the microscopic scale becomes small compared to the scale induced by the frequencies of the imposed currents. After defining a singular value decomposition of the non-selfadjoint partial differential operator, we expand the electromagnetic field in the modes corresponding to the singular values, and show that only the

in this chapter (nr 2), i briefly present the career and the works of Bruno K. Öijer. I also analyse some of the main literary themes in his production, from the debut in 1973, up til the so far latest book, the collection of poems "Svart som silver" (2008).

Today’s architecture swarms with concepts of energy and resource efficient buildings. In contrast, vernacular buildings are characterized by low-tech climatic responsive strategies and by their inhabitants’ resource and energy savings practices during construction and operation of their dwellings. That makes vernacular buildings highly relevant to resource efficiency in contemporary building resea
The content of this report is a deliverable to the FP 7 project RUFUS (Rural future Networks) concerning the case studies made within the project. As a deliverable in a EU framework project it reports extensively on the methods and empirical data collected in the project’s case studies. The work has as an overarching motive to translate research findings into implications that are relevant for pol
