In this paper, an investigation is done into the potential of increasing the coolant temperature of an engine to maximize the powertrain efficiency. The study takes a holistic approach by trying to optimise the combined engine and waste heat recovery system. The work was done experimentally on a Volvo 4-cylinder light duty diesel engine in combination with Rankine cycle simulations. For the study,
A two-dimensional mathematical model is used to investigate the performance and transport characteristics of PEM fuel cells with different membrane thicknesses. The overall cell performance of three cases are presented and compared. In addition, the local temperature, liquid water saturation, water content and current density distributions are analyzed and compared. Results show that performance i
Anyone who teas taught a course in Strategic Management probably provides the same basic content to students including the infamous SWOT (strengths, weaknesses, opportunities and threat) analysis along with the identification of functional level, business level, and generic strategies to enhance an organization's competitiveness. What might be different in the teaching of strategic management cour
Food high in energy but low in nutritional value is an important contributor to several serious illnesses, and one type of food that is particularly high in energy but low in nutrition is food consumed away from home. In this paper, we examine the demand and willingness to pay for healthy, Keyhole-labelled meals. A Keyhole-labelled meal is particularly low in calories, fat, sugar and salt, but par
This paper discusses the possible advantages and disadvantages by using experimental methods in order to understand how music influences our understanding of film narratives. Can experimental and quantitative methods such as eye tracking, questionnaires, galvanic skin response, EEG (electroencephalogram) and fMRI (functional magnetic resonance imaging – a brain scan) give us insights into the sign
Basing my conclusions on Mainland Scandinavian, primarily Swedish, I argue that a strict division has to be made between three concepts or dimensions of gender: formal gender, semantic gender and lexical gender. Lexical gender is a salient meaning component of a noun; this dimension of gender is syntactically inert. Semantic gender is a category of thought, conveyed by pronominal resources. Semant
Discussions about changing the focus of assessing development progress from economic output to human well-being have sparked a rise in interest in the social sciences' research on subjective well- being in recent years. Such a transition necessitates investigating subjective well-being, its determinants, and how they interact with one another. Previous studies show ambiguity in describing the

In this note we establish that the probability that the simple random walk on Z2 returns to its origin before leaving a strip of width L has asymptotically the same probability as the one for hitting the origin before exiting the centered box of the same size. We also generalize this theorem for fairly arbitrary sequences of increasing sets in Z2.
We study boundedness properties of a class ofmultiparameter paraproducts on the dual space of the dyadic Hardy space H (d) (1) (T (N) ), the dyadic product BMO space BMO (d) (T (N) ). For this, we introduce a notion of logarithmic mean oscillation on the polydisc. We also obtain a result on the boundedness of iterated commutators on BMO [0, 1] (N) ).
This review discusses actual and potential contributors to functional improvement after stroke injuries. Topics that will be covered are neuronal re-organization and sprouting, neural stem/progenitor cell,activation and neuronal replacement, as well as the neuronal milieu defined by glia, inflammatory cells and blood vessel supply. It is well established that different types of neuronal plasticity
The aim of this study was to investigate from the perspective of formal carers the care given to people aged 65 and over, who are cared for in their own homes by informal care. Thirty-three district nurses (DNs) and 20 home service assistants in a municipality with 13500 inhabitants (over 65 years old), were interviewed about the location of care recipients and 398 care recipients were located. Mo
BACKGROUND: In assisting the nurse's counselling on lifestyle changes in hypertension care a behaviour model can be used. AIM: To analyse the effects of nurses' training on the use of the stages of change model when counselling hypertensive patients to perform lifestyle changes. METHODS: As part of a randomised, controlled trial, 19 nurses belonging to the intervention group took part in video-rec
Precipitation suppression due to an increase of aerosol number concentration in stratiform cloud is well-known. It is not certain whether the suppression applies for deep convection. Recent studies have suggested increasing precipitation from deep convection with increasing aerosols under some, but not all, conditions. Increasing precipitation with increasing aerosols can result from strong intera
Campylobacter, Helicobacter and Wolinella are genera of the order Campylobacterales, belonging to the class Epsilonproteobacteria. Their habitats are various niches in the gastrointestinal tract of higher animals, where they may come into contact with bile. Microorganisms in these environments require mechanisms of resistance to the surface-active amphipathic molecules with potent antimicrobial ac
A lysimeter method was evaluated for its suitability in gas emission studies by studying the effect of temperature on CO2 emissions (dark respiration) from cultivated peat soils. The study was carried out with organic soils from two locations in Sweden, a typical cultivated fen peat with low pH and high organic matter content (Orke) and a more uncommon fen peat with high pH and low organic matter
This paper presents an existence and stability theory for gravity-capillary solitary waves on the surface of a body of water of infinite depth. Exploiting a classical variational principle, we prove the existence of a minimiser of the wave energy epsilon subject to the constraint I = root 2 mu, where I is the wave momentum and 0 < mu << 1. Since epsilon and I are both conserved quantities a standa
