Force and isotonic shortening velocities were studied (0.6-4.0 degreesC) in isolated single muscle spindles from the anterior tibialis muscle of Rana temporaria using techniques that enabled measurements both from the spindle as a whole and from marked segments of the preparation. The force-velocity relationship during tetanic stimulation exhibited the same biphasic shape as previously described f
The application of k(t)-factorization supplemented with the CCFM small-x evolution equation to heavy quark production is discussed. The b (b) over bar production cross sections at the TEVATRON can be consistently described using the k(t)-factorization formalism together with the unintegrated gluon density obtained within the CCFM evolution approach from a fit to HERA F-2 data. Special attention is
In order to contribute to knowledge on how-to expand bioenergy this paper examines an example of success from Sweden. The idea is to identify factors that can explain the difference between success and failure of bioenergy systems. In the aftermath of the oil crises in the 1970s, the local government in the town of Enkoping in Sweden was cautioned by the local Swedish military regiment to shift to
In our previous studies we have used electrolytic conductivity detection (ELCD) in the selective analysis of chlorinated fatty acids in marine samples. In order to determine the chlorinated fatty acids quantitatively, we studied the ELCD response factors (RFs) of chlorinated fatty acids and compared them with those of other chlorinated compounds. We also studied the effect of reactor temperature a
The time domain version of the optical theorem is discussed. The theorem is derived from the optical theorem in the frequency domain by the Parseval's relation. It expresses the sum of the scattered and absorbed energies in terms of the scattered farfield in the forward direction. From the theorem, causality, and reciprocity, a number of results concerning the scattered and absorbed energies from
Mute Swans (Cygnus olor) and Whooper Swans (Cygnus cygnus) in Sweden have been monitored as part of the International Waterbird Census (IWC) since 1967. For the Whooper Swan, midwinter indices show fluctuations around a slowly increasing trend. Country-wide surveys in 1971-72, 1988-89, 1995 and 2000, however found a more substantial increase in numbers, with national totals estimated at 2,000, 4,0
Essä om Douglas Sirk som filmregissör, hans berättarstil och teman.
We tested the relative and combined effects of prey density and patch size on the functional response (number of attacks per unit time and duration of attacks) of a predatory reef fish (Cheilodactylus nigripes (Richardson)) to their invertebrate prey. Fish attacked prey at a greater rate and for longer time in large than small patches of prey, but large patches had naturally greater densities of p
A new trend of product-service systems (PSS) that has the potential to minimise environmental impacts of both production and consumption is emerging. This article attempts to build a theoretical framework for PSS and serves as a background for identifying possible investment needs in studying them. There are three main uncertainties regarding the applicability and feasibility of PSS: the readiness
A novel technique, involving U-model based IMC (internal model control), is proposed for the adaptive control of nonlinear dynamic plants such as the DC-motor. The proposed scheme combines the robustness of the IMC and the ability of neural networks to identify arbitrary nonlinear functions, with the control-oriented nature of the U-model to achieve adaptive tracking of stable nonlinear plants. Th
Oat-based beverages enriched with vitamins and minerals were produced with common hydrothermal treatments and stored at 22 degrees C for 64 weeks. The effects of decanting on the retention of native vitamins, minerals and fatty acids, and different UHT holding time (5 s or 20 s) at 140 degrees C on vitamins were investigated. Fatty acid profile, vitamin retention and dissolved oxygen concentration
This thesis deals with some aspects of description in Julien Gracq’s fiction. These aspects are selected as a result of a double investigation. Firstly, the theory of description as it has taken form with the contributions of Barthes, Genette, Ricardou, Bal, Riffaterre, Hamon, Weinrich, Adam and Petitjean, Reuter, Molino, Brassart is presented. Secondly, the main critical analyses of description i
HERA provides a unique possibility to investigate the dependence of multiple interactions on transverse interaction sizes through variation of the photon virtuality Q2. In order to observe effects of multiple interactions at Q2 substantially different from zero we have to look into regions of phase space where resolved processes dominate over direct ones. The forward jet production at small values
