In this paper, we show that the widely accepted method of the determination of Curie temperature (Tc) in (Ga,Mn)As samples, based on the position of the peak in the temperature derivative of the resistivity, completely fails in the case of non-metallic and low-TC unannealed samples. In this case, we propose an alternative method, also based on electric transport measurements, which exploits temper

The Chinese government has been promoting the anaerobic treatment technology not only for pollution control but also for bioenergy recovery. Millions of decentralized anaerobic digesters have been built using animal manure and crop stalk as feedstock to improve the sanitary conditions and to produce biogas for heating and lighting for farmers and rural communities. Also, there are 22,570 medium to

In the past decade, a growing number of countries have established national councils for innovation or for science, technology and innovation. The interest in innovation councils responds to a growing need for strengthening the coordination, inclusiveness and, ultimately, the effectiveness of innovation policy governance.In Sweden, the National Council for Innovation and Quality in the Public Sect

Bergskedjor är uppbyggda av olika slags berggrund som skjutits samman i de zoner på Jorden där tektoniska plattor möts (konvergerar). Sådana processer sker i dag exempelvis i Himalaya, Alperna eller Anderna, men det finns också gamla, nu inaktiva, bergskedjor som de Skandinaviska Kaledoniderna (ca 400 miljoner år gammal) eller den Svekonorvegiska bergskedjan (ca 1000 miljoner år gammal, i sydvästrThe 1.1-0.9 Ga Sveconorwegian orogen is one of several Grenvillian-aged orogenic belts that mark the amalgamation of supercontinent Rodinia. The highest-pressure rocks in the Sveconorwegian orogen are eclogites in the Eastern Segment (SW Sweden). The eclogites occur in a nappe in the high-grade metamorphic level of the Eastern Segment that represents a window into the deepest part of this Precambr

We use Granger causality to investigate the influences of external forcings on subdecadal variability of regional near-surface air temperature (SAT) in past millennium simulations (period 850–1850 A.D.) of the Coupled Model Intercomparison Project Phase 5 (CMIP5) models. Our results strengthen the conclusion for robust influence of volcanic forcing on SAT during preindustrial times of the last mil

This paper proposes a new frequency domain method to model the heat transfer between the injected/extracted heat and the temperature of the fluid exiting a borehole heat exchanger. The method is based on in situ measurements and focuses particularly on the short-term borehole heat transfer. It uses a rational function of the Warburg variable in the Laplace domain to model the borehole heat transfe
