This report presents a derivation of the Furuta pendulum dynamics using the Euler-Lagrange equations.

Popular Abstract in Swedish I Norra Skandinavien, liksom i andra kalla områden, är oftast de urbana dräneringssystemen inte kapabla att föra bort de stora volymer smältvatten som ofta belastar systemet under flera veckor under snösmältningen. Högt vattenflöde till reningsverk, översvämning av kombinerade system och låg vattenkvalitet är några problem förknippade med snösmältning. Trots detta är raIn northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. However, reports detailing urban snowmelt processes are lacking in the hydrological literat

We present two-dimensional numerical simulations of a model for Kepler's supernova remnant (SNR) carried out with the YGUAZU-A code. Following previous studies, we have assumed that the peculiar shape of this young remnant arises as a consequence of the interaction of the SNR blast wave with the bow shock formed by the wind of its high velocity progenitor. Furthermore, from our numerical results w

Indian meal moths, Plodia interpunctella Hubner ( Lepidoptera: Pyralidae), have ears which are sensitive to high-frequency calls produced by echolocating, insectivorous bats. The influence of artificially generated, high-intensity, ultrasound signals (25 kHz, 106 dB SPL at 1 m distance) on different parameters involved in the odour-mediated mating behaviour of this species and its potential use in

The selective blockade of alpha1-adrenoceptors (ARs) is now a well-accepted and widely used treatment for patients presenting with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) and bladder outlet obstruction. The sites of action of the currently used alpha1-AR antagonists when relieving LUTS have not yet been established, but it seems clear that effects on

Wild-type (F/B), constitutively active (F/B*), and three kinase-inactive (F/Ba-, F/Bb-, F/Bc-) forms of Akt/protein kinase B (PKB) were permanently overexpressed in FDCP2 cells. In the absence of insulin-like growth factor-1 (IGF-1), activities of PKB, cyclic nucleotide phosphodiesterase 3B (PDE3B), and PDE4 were similar in nontransfected FDCP2 cells, mock-transfected (F/V) cells, and F/B and F/B-

This article discusses developments in the area of product service systems (PSS) and the need to facilitate the proliferation of the PSS approach through public policies. The article argues that policies that establish the framework conditions for environmental improvement are preferable to detailed legislation as they favour environmentally superior PSS. However, there is also a need for more spe

The functional implication of previously shown effects on pial wall morphology by sympathectomy was tested. Following either ganglionic or pre-ganglionic denervation in 1-week-old rats the passive arterial compliance was reduced in basal cerebral arteries of 20-week-old normotensive, but not of hypertensive animals. The magnitude of the denervation induced stiffness was similar to the alteration s

The proposed experiments for the first RISING (Rare ISotope INvestigations at GSI) campaign will exploit secondary unstable beams at relativistic energies in the range from 100 MeV/u to 400 MeV/u. The RISING spectrometer will be employed for relativistic Coulomb excitation and for high-resolution gamma-spectroscopy experiments after secondary nucleon removal reactions and secondary fragmentation.

Active Photosystem II (PS II) cores were prepared from spinach, pea, Synechocystis PCC 6803, and Thermosynechococcus vulcanus, the latter of which has been structurally determined [Kamiya and Shen (2003) Proc Natl Acad Sci USA 100: 98-103]. Electrochromic shifts resulting from Q(A) reduction by 1.7-K illumination were recorded, and the Q(x) and Q(y) absorption bands of the redox-active pheophytin

Twenty parents of boys (ages 2-14 years) hospitalized for hypospadias repair in a pediatric surgery department in Sweden, were interviewed concerning their experience when their child was hospitalized. A qualitative analysis of the interviews indicated that the most important issue to the parents was finding security at the hospital. Parents manifested one of three different strategies that enable

Reduced capacity to produce ROS increases the severity of T cell-dependent arthritis in both mice and rats with polymorphisms in neutrophil cytosolic factor 1 (Ncf1) (p47phox). Since T cells cannot exert oxidative burst, we hypothesized that T cell responsiveness is downregulated by ROS produced by APCs. Macrophages have the highest burst capacity among APCs, so to study the effect of macrophage R
