Rewritable Reference Attributed Grammars (ReRAGs) is a recently developed compiler-compiler technology based on object-orientation, aspect-orientation, reference attributed grammars, and conditional rewrites. In this paper we describe our experiences from using ReRAGs for implementing Java compilers. We illustrate how the usage of ReRAGs renders a rather compact, yet easy-to-understand and modular

This paper presents a computational study of the combustion process of wood pellets in a small-scale grate fired furnace. The objectives were to obtain detailed information on the combustion characteristics and NO formation in the furnace, and to examine the effect of secondary air on the combustion process. The simulation results were compared with experimental data in terms of flame temperature

One of the central bones of contention in the study of the European Union (EU) is the capacity of its supranational institutions to be a driving force in the process toward deeper integration. Whereas existing research predominantly addresses the institutions’ ability to shape European integration through pre-decisional agenda-setting, this study examines the scope for supranational influence in t

Objective. When treatments with the potential to change the natural history of a disease are introduced, their longer-term effect on costs and quality of life (utility) has to be estimated using economic models. However, to remain useful tools, models must be updated when new information becomes available. Our earlier models in rheumatoid arthritis (RA) have been based on functional status, but it

Excited states in 86,88Mo have been identified using recoil-gamma and gamma-gamma coincidences. Energy-level systematics of the molybdenum isotopes from the N = Z line to the N = 50 shell closure are compared to their strontium and zirconium neighbors. This comparison, an estimate of the B(E 2) strengths, and a Woods-Saxon cranking model have been used to suggest that the molybdenum isotopes under

The role of the exocrine pancreas in regulating gut microflora colonization is unclear. The main objective in the present study was to assess the affect of pancreatic fluid on the growth of pathogenic bacteria and fungi. Pancreatic juice samples used in the study were obtained from nine eight-week old weaned pigs in which catheters were implanted in the pancreatic duct. The antibacterial activity

OBJECTIVE: To study the association between polymorphisms in the angiotensin converting enzyme (ACE) gene and angiotensinogen (AGT) gene and hypertension and/or type 2 diabetes in a community population. PATIENTS AND METHODS: The insertion (I)/deletion (D) polymorphism of the ACE gene and the M235T polymorphism of the AGT gene were genotyped in 773 nondiabetic individuals with hypertension, 193 no

A brief introduction to convolutional coding is given. The active distances are reviewed and shown to be an important tool for analyzing the error correcting capability of maximum-likelihood (ML) decoding of convolutional codes when communicating over a binary symmetric channel (BSC). Due to memory and delay constraints in practical coding schemes, convolutional codes often are either terminated o

A charging unit for unipolar charging of cloud and fog droplets has been developed and calibrated regarding ion current, angular distribution of ions, mean droplet charge and droplet charge distribution. The charger is part of the droplet aerosol analyser, which is an instrument used for characterisation of droplets and interstitial particles in atmospheric clouds and fog. Three different calibrat

The enzymatic synthesis of dipeptide units of the d-d-configuration in aqueous media, catalysed by muramoyl-pentapeptide carboxypeptidase (E.C.3.4.17.8), is described. Ac-l-Lys(Ac)-d-Ala-d-Lac-OH and Ac-d-Ala-OMe were used as acyl-components. Neutral, basic, and hydrophobic amino acids acting as nucleophiles were incorporated. The enzyme is stereospecific in that only the d-enantiomers of amino ac

According to the polygyny threshold model, females are compensated for the cost of sharing a territory with other females by breeding in territories of higher quality than those of monogamously mated females. In the polygynous Great Reed Warbler (Acrocephalus arundinaceus), the variation in territory quality may be associated with nest site characteristics or food supply. In this study, we examine

The number of elderly people is gradually increasing, and with it the number of persons receiving some kind of care in their everyday lives. However, researchers and the mass media recurrently report great difficulties for many caregivers in their work situations. This article considers process-oriented supervision as a pedagogic method for training and support of nurse aids and managers in Swedis

Differential dijet cross sections are measured in photoproduction in the region of photon virtualities Q(2) < 1 GeV2 with the H1 detector at the HERA ep collider using an integrated luminosity of 66.6 pb(-1). Jets are defined with the inclusive k perpendicular to algorithm and a minimum transverse momentum of the leading jet of 25 GeV is required. Dijet cross sections are measured indirect and res

The fluoroquinolone sensitivity of Pseudomonas aeruginosa and Klebsiella pneumoniae was studied by determinations of Minimum Inhibitory Concentrations (MICs) of norfloxacin and ciprofloxacin in consecutive clinical isolates. In P. aeruginosa, resistance or reduced susceptibility (MIC > or = 8 mg/l for norfloxacin and > or = 2 mg/l for ciprofloxacin) was found in 17% (9/54) of the isolates. Reduced
