An atomic force microscope was used to directly examine the physical state of nanometer-sized particles. The critical diameter of indium particles, where evidence of melting at room temperature was observed, was 7.8±1.2 nm. This conclusion is based on a method relying on the manipulation of particles in ambient air and at constant temperature. This method involves a simple set up that permits a co

From its inception, “animal magnetism” and hypnosis have been related to reputed psi phenomena. However, only until recently have phenomenological and neurophysiological approaches advanced enough to go beyond a putative –and vague- hypnotic state. In this study we are following a neurophenomenological approach by analyzing in parallel experience and brain processes. We selected a group of individ

Methods to achieve admittance matching of rectangular dielectric resonator antennas intended for 60~GHz impulse radio are reported. The motivation is to find a suitable antenna that may be integrated in the V-band gated tunnel diode wavelet generator, replacing its tank circuit and forming a low complexity transmitter. Probed one- and two-port scattering parameter measurements have been performed

Today, innovation is a key word for many universities, as it constitutes an important part of most universities’ public and scientific interaction with society. Many universities are striving to increase the number of innovations spun out. At many universities, innovations are thought of as being sprung from research projects and generated by researchers. However, Sandström (2014) claims that whil

Popular Abstract in Swedish I takt med att den stratosferiska ozonskikten tunnas ut når mera av solens skadliga ultraviolet-B strålning (UV-B, 280 - 320 nm) jordytan. I avhandlingen beskrivs det effekter av ökad UV-B strålning på komponenter (mossor) och processer (nedbrytning av förna, biomassa produktion, arternas samspel) i ekosystem på höga breddgrader. Experiment utfördes där en hed och en myBiologically harmful ultraviolet-B radiation (UV-B, 280-320 nm) is increasing at the Earth´s surface owing to stratospheric ozone depletion. This is of global concern due to potential impacts of enhanced UV-B radiation on the biosphere. The aim of this thesis was to investigate effects of enhanced UV-B radiation on components (bryophytes) and processes (decomposition, productivity, species interac

In this paper a method for reconnecting islanded distributed generation systems is presented. Islanding of a distributed generation system may result from a fault or malfunction of protective elements. The behavior of local voltage and frequency control in case of islanding is investigated. A method for reconnecting the distributed generation system and the behavior of voltage and frequency contro
