BACKGROUND Tannins can bind to and precipitate protein by forming insoluble complexes resistant to fermentation and with a positive effect on protein utilisation by ruminants. Three protein types, Rubisco, rapeseed protein and bovine serum albumin (a single high-molecular weight protein), were used to test the effects of increasing concentrations of structurally different condensed tannins on prot

In contemporary nuclear physics, the European Advanced GAmma Tracking Array (AGATA) represents a crucial detection system for cutting-edge nuclear structure studies. AGATA consists of highly segmented high-purity germanium crystals and uses the pulse-shape analysis technique to determine both the position and the energy of the γ-ray interaction points in the crystals. It is the tracking algorithms

The critical effect of load representation in voltage stability studies is discussed in this paper. Under the same conditions in the system, the load representation will affect the location of the operating point in a P-V curve representation, leading the system closer to or further from the collapse point. The use of dynamic load models in voltage stability studies is motivated, especially in tho

Accidents and injuries caused by electricity are work environment risks for electricians. About a 100 cases are reported annually to the Swedish Work Environment Authority. The safety culture at the electricians’ workplaces can affect the successfulness of safety management and the prevention of injuries. This paper presents preliminary questionnaire and interview findings on the perceived workpla

Delays and cost overruns are frequent problems in the construction industries of both developed and developing countries. Studies aimed at identifying the causes are often undertaken with just a broad appreciation of the construction process and frequently do not deal with multicultural issues when considering the reasons for overruns. The paper critically reviews existing attempts to uncover the

Following a brief discussion on aspects of visual appearance and roles respectively, two user studies are presented and discussed. Both focus on learner experiences and explore the reciprocal relation between visual appearance of virtual agents and their pedagogical roles. The paper concludes with some preliminary guidelines for the early stages of the design process of virtual pedagogical agents.

The present international standards for safety, protective and occupational footwear EN ISO 20344 – 20347 classify footwear as cold protective by a pass/fail test where the limits are set for an allowed 10 °C temperature drop inside the footwear at a sole location during 30 minutes at a temperature gradient of about 40 °C. In a test of five footwear including a summer sandal it was shown that all

Fractional exhaled nitric oxide is elevated in allergen-provoked asthma. The cellular and molecular source of the elevated fractional exhaled nitric oxide is, however, uncertain.

Objectives: The aim of this study was to evaluate the efficacy of the natural antioxidant astaxanthin in functional dyspepsia in different doses and compared with placebo. Design: The study was a controlled, prospective, randomized, and double blind trial. Participants: Patients with functional dyspepsia, divided into three groups with 44 individuals in each group (placebo, 16 mg, or 40 mg astaxan

Ovarian masses are common and a good pre-surgical assessment of their nature is important for adequate treatment. Bayesian Multi-Layer Perceptrons (MLPs) using the evidence procedure were used to predict whether tumors are malignant or not. Automatic Relevance Determination (ARD) is used to select the most relevant of the 40+ available variables. Cross-validation is used to select an optimal combi

Most works published on iterative CDMA receivers assume perfect channel knowledge or very simple channel models like the flat-fading channel. We want to extend the scope to multipath propagation scenarios and suggest an iterative scheme with channel estimation in the uplink of a chip-synchronous CDMA system. Channel estimates rely on pilot symbols and a posteriori probabilities on code bits of a S

BackgroundIncidence of condyloma, or genital warts (GW), is the earliest possible disease outcome to measure when assessing the effectiveness of human papillomavirus (HPV) vaccination strategies. Efficacy trials that follow prespecified inclusion and exclusion criteria may not be fully generalizable to real-life HPV vaccination programs, which target a broader segment of the population. We assesse

The ESA space astrometry mission Gala, due for launch in early 2012, will in addition to its huge output of fundamental astrometric and astrophysical data also provide stringent tests of general relativity. In this paper we present an updated analysis of Gaia's capacity to measure the PPN parameter gamma as part of its core astrometric solution. The analysis is based on small-scale astrometric sol

The early science results from the new generation of high-resolution stellar spectroscopic surveys, such as Galactic Archaeology with HERMES (GALAH) and the Gaia European Southern Observatory survey (Gaia-ESO), will represent major milestones in the quest to chemically tag the Galaxy. Yet this technique to reconstruct dispersed coeval stellar groups has remained largely untested until recently. We

New laminar burning velocity measurements of 85: 15% (by volume) H-2-CO and H-2-N-2 mixtures with O-2-He oxidizer are reported at lean conditions and elevated pressures (1-10 atm). Experiments are conducted using the heat flux method at initial temperature of 298 K. In this technique a near adiabatic flame is stabilized by balancing the heat loss from the flame to the burner with heat gain to the
