Depending on the maximum amplitude of externally applied cyclic electric fields, ferroelectric ceramics show minor or major hysteresis. The materials also show asymmetric butterfly hysteresis in a prepoled material. Aiming at capturing these behaviour in a phenomenological constitutive model, a multi-surface modelling approach for ferroelectrics is introduced. In this paper, with the note on the m

pH is an important parameter affecting heavy metal toxicity in soil. Bacterial and fungal growth, and respiration, during 60 days were determined in response to Cu additions (up to 32 mmol Cu kg-1 soil) in four soils with pH varying between 4.5 and 7.8. We hypothesized that at higher pH the toxic effect of Cu would decrease. In soil with pH 7.8, no negative effects on microbial growth were found u

Our future built environment will not only consume energy, it will also produce (partly) its own energy need. Solar energy has been proven to be a valid strategy for producing on-site renewable energy. Planning for integrating solar energy in buildings involves many players and decision-making. In this article, a process map defining which decisions regarding solar energy needs to be discussed in

The obligation to prosecute or extradite is a growing sensitive issue in international law. In the recent case Questions Relating to the Obligation to Prosecute or Extradite (Belgium v. Senegal), the International Court of Justice was confronted with determining a breach to the obligation to prosecute or extradite in relation to acts of torture set forth in Article 7(1) of the 1984 UN Convention A

A coarse-grained model has been implemented using the Metropolis-Hastings Monte Carlo method to simulate β-casein and acidic proline-rich protein 1 (PRP-1). The aim of the study is to directly compare the properties and behavior of β-casein and PRP-1, in both bulk solution and in the presence of a negatively charged surface, in order to evaluate the possibility of using β-casein as a replacement f

We have studied the nature of the S 2p → 4eg shape resonance in the SF6 molecule by performing two different experiments. Soft X-ray emission spectra measured at the 4eg shape resonance reveal features that do not originate from the S 2p-1 states. One of the features can be assigned to the 6a1g → S 2p transition. The 6a1g orbital, which is empty in the molecular ground state, can be populated eith

It is well known that the water-wave problem with weak surface tension has small-amplitude line solitary-wave solutions which to leading order are described by the nonlinear Schrödinger equation. The present paper contains an existence theory for three-dimensional periodically modulated solitary-wave solutions which have a solitary-wave profile in the direction of propagation and are periodic in t

The influence of oat and barley β-glucans on some features of diverse probiotic strains was investigated. Neither barley nor oat β-glucans supported the growth of any of the investigated strains when used as the sole carbon source in fermentation media. No protective effect by β-glucans was observed on bacterial survival to in vitro simulation of the human digestive tract. Moreover, the presence o

The Parabolic Synthesis methodology is an approximation methodology for implementing unary functions, such as trigonometric functions, logarithms and square root, as well as binary functions, such as division, in hardware. Unary functions are extensively used in baseband for wireless/wireline communication, computer graphics, digital signal processing, robotics, astrophysics, fluid physics, games

The silicon isotope composition of biogenic silica (δ30SiBSi) in the ocean is a function of the δ30Si of the available dissolved Si (DSi; H2SiO4), the degree of utilisation of the available DSi, and, for some organisms, the concentration of DSi. This makes δ30SiBSi in sediment archives a promising proxy for past DSi concentrations and utilisation. At steady-state, mean δ30SiBSi must equal a weight

Abstract in UndeterminedExtreme down-scaling of nanoelectronic devices by top-down fabrication methods may be hindered by several obstacles, such as the cost for patterning and processing, or inferior device performance due to process-induced damage. In this presentation I will present a bottom-up approach for nanometer-scale device fabrication, based on seeded growth of semiconductor nanowires, u

The present paper argues that the prolonged insurgency in southern Thailand has gone through changes since the outbreak of major violence in 2004. An analysis of the dynamics of the conflict, and its relation to economic and social factors, can improve our understanding of the drivers of conflict. A key finding is that the bulk of the violence has shifted from poor rural districts to more affluent

Ingen enskild person har utövat ett så djupgående inflytande som Henric Schartau (1757–1825) på kyrkolivet i södra och västra Sverige under 1800- och 1900-talen. Han gav själv inte ut sina skrifter, men av ingen annan svensk teologisk författare torde så mycket ha publicerats. Hans teologiska och kyrkliga ståndpunkt präglades av en ibland ensidig koncentration på det enda nödvändiga. Han gav namn
