The task of specifying a brake system for a vehicle is without doubt one of the most crucial decisions a design manager must undertake in the development process of a vehicle. Improved vehicle aerodynamics, higher loads, more horsepower and increased road safety all create the need for more effective brake systems. The most dominant of these is the disc brake system, due to the absence of fade and

The purpose of the present study was to investigate the rate of deliberate self-harm in 15-year-old Swedish adolescents, gender differences in this behavior, and possible associations with self-esteem and mindfulness. For this purpose, we developed a simplified version of Gratz's (2001) Deliberate Self-Harm Inventory (DSHI), and carried out a pilot study with 123 adolescents from three different s

Laschiatrion (1), a new antifungal antibiotic, was isolated from fermentations of Favolaschia sp. 87129. (1) exhibits broad in vitro activity against several human pathogens while no antibacterial and cytotoxic activities could be detected. The structure was elucidated by spectroscopic techniques. As to our knowledge laschiatrion possesses a new steroid skeleton.

Pre-treatment of sludge before anaerobic digestion can increase methane production and degradation of organic matter. There are various pre-treatment methods for this purpose. Anaerobic digestion tests were performed for comparison of three pre-treatment methods (hygienisation, ultrasonic treatment and enzyme dosing) used separately or in combination on biosludge and mixed sludge. COD solubilisati

Organic films were collected from indoor and outdoor window surfaces, along an urban-rural transect extending northward from Toronto, Ontario, Canada, and analyzed for 41 polybrominated diphenyl ether congeners (PBDE). For exterior films, urban SigmaPBDE concentrations were similar to10x greater than rural concentrations, indicating an urban-rural gradient and greater PBDE sources in urban areas.

A series of ab initio calculations employing a modified Langevin dipoles method to model neutral, cationic, and anionic cis-urocanic acid in human skin is presented. A comparison between the stability of the conformers in gas phase and in a condensed phase is performed. In particular, the energy barrier and transition state of the isomerization reaction of the anionic forms of cis-urocanic acid ha

BACKGROUND: The role of cholecystokinin (CCK) and gastrin in the development and growth of pancreatic cancer cells is controversial. The aim of this study was to evaluate the role of CCK-8S, gastrin-17, bombesin, and their antagonists on cell lines from patients with pancreatic cancer. METHODS: Cell lines were established from pancreatic cancers operated on at our department. The cells were grown

Landfilling in "cells" has become more common in recent years. Different waste streams are guided to different cells, among which the biocell is a landfill designed for biogas production. In this thesis, the dependence of biogas generation on waste composition was investigated. Six 8,000 m3 test cells, with contents ranging from mainly commercial waste to pure domestic waste and equipped with gas

A general formula is derived for the finite volume dependence of vacuum expectation values analogous to Luscher's formula for the masses. The result involves no integrals over kinematic quantities and depends only on the matrix element between pions at zero momentum transfer thus presenting a new way to calculate the latter, i.e. pion sigma terms. The full order p(6) correction to the vacuum conde

Väderdata från 10 olika meterologiska mätstationer i Sverige - Kiruna, Luleå, Frösön, Söderhamn, Karlstad, Bromma, Jönköping, Säve, Ronneby och Sturup - för tidsperioden 1961 till 1990. De aktuella väderparametrarna är temperatur, relativ fuktighet, ånghalt, mättnadsånghalt, vindhastighet, vindriktning, nederbörd, solstrålning och långvågig strålning.

Objective-The objective of this study was to determine the conduction properties of the normal atrioventricular (AV) conduction system in relation to accessory pathway (AP) location in patients with symptomatic Wolff-Parkinson-White syndrome. Design-The conduction properties of the AP and the AV node were studied in 356 patients with single manifest AP who underwent successful ablation. Results-Si

This paper presents theory for stability analysis and design for a class of observer-based feedback control systems. Relaxation of the controllability and observability conditions imposed in the Yakubovich-Kalman-Popov (YKP)lemma can be made for a class of nonlinear systems described by a linear time-invariant system (LTI) with a feedback-connected cone-bounded nonlinear element. It is shown how a
