This study evaluates the costs associated with foraging for birds in a savannah woodland area in central Nigeria. Specifically, it looks at the following questions: 1) how does seasonal variability in food and water availability affect the value of resources to birds in dry environments? 2) Does proximity to water affect foraging decisions? What implication will this have in the management of sava

Five sets of gloves were tested on 3 hand models with 2 measuring system in order to ensure repeatability of results from the past and for the future. The other aims of the study were to compare the possible differences related to different number of measuring zones, and effect of temperature distribution over hand surface. The hand models had 2 (HF), 9 (H2) and 10 (H3) zones respectively. Models

This paper develops a procedure for estimating parameters of a cross-sectional stochastic frontier production function when the factors of production suffer from measurement errors. Specifically, we use Fuller's (1987) reliability ratio concept to develop an estimator for the model in Aigner et al (1977). Our Monte-Carlo simulation exercise illustrates the direction and the severity of bias in the

Svensk statsförvaltning genomgår, precis som privat sektor, ständigt förändringar och omstruktureringar, drivna av olika samhällstrender, ledarskapsidéer och politiska styrfilosofier. Vid dessa förändringar ställs verksamheten inför vägval som på olika sätt kan påverka dess förmåga att leva upp till omgivningens krav och förväntningar. Samtidigt finns inte utrymme för risktagande, eftersom förvalt

Piety and modernity is presented in Britain, Ireland, Scandinavia, Germany, and the Low Countries between 1780 and 1920. Emphasis is put on piety and politics, pious nationalism, pious enlightenment, piety and romanticism, Moravian and Evangelical inspiration, on communciations and mentalities, on gender aspects on pious language, assocatiational activities, minorities, as well as on the instrumen

Popular Abstract in Swedish Sekvensbaserade proteinveckningsmodeller utvecklas och testas på peptider med både betablad- och alfahelix-struktur, samt på små helix-proteiner. Modellernas potentialer är minimalistiska och baseras huvudsakligen på vätebindningar och effektiva hydrofobicitetskrafter. Den geometriska representationen av proteinkedjan är däremot detaljerad. Vi studerar det termodynamiskSequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. By contrast, the geometric representation of the protein chain is detailed. We explore the thermodynamic behav

Visual quality assurance techniques focus on the detection and qualification of abnormal structures in the image of an object. The features of abnormality are extracted through image mining, whereupon classification is performed on characteristic combinations. Many techniques for feature extraction have been proposed, but the feed-forward neural network is seldom utilized despite its popularity in

This article deals with study of ionization current sensing technique's signal characteristics while operating with pre-chamber spark plug to achieve plasma jet ignition in a 6 cylinder 9 liter turbo-charged natural gas engine under EGR and excess air dilution. Unlike the signal with conventional spark plug which can be divided into distinct chemical and thermal ionization peaks, the signal with p

We review the current knowledge on biodiversity in soils, its role in ecosystem processes, its importance for human purposes, and its resilience against stress and disturbance. The number of existing species is vastly higher than the number described, even in the macroscopically visible taxa, and biogeographical syntheses are largely lacking. A major effort in taxonomy and the training of a new ge

With increasing usage of the Internet, energy consumption of network equipment has become a crucial challenge from both an economic and an environmental point of view. This paper combines users’ behavior of accessing the network with energy saving algorithms for energy-aware network equipment, and investigates potential energy savings in the access network. The study is based on a set of traffic d
