The key success factor for companies is to develop and deliver services and products that satisfy customer needs and create customer value. When introducing e-businesses as a new channel, it is becoming increasingly important to consider customers, since they will have a higher level of influence on the company through the interactive channel. This paper sets out to describe the process of conside
The effects of the physical-spatial-technical environment on aging well have been overlooked both conceptually and empirically. In the spirit of M. Powell Lawton's seminal work on aging and environment, this article attempts to rectify this situation by suggesting a new model of how older people interact with their environment. Goals of the paper include (a) integration of the essential elements o
This article presents a polar diagram method developed for describing and evaluating the potential machinability of different workpiece materials. The potential machinability is examined in terms of five critical properties of the workpiece material. Two groups of materials, a group of common steel grades and the other a group of stainless steels, were examined in detail, their polar diagrams illu
Understanding the role of electrostatics in protein stability requires knowledge of these interactions in both the folded and unfolded states. Electrostatic interactions can be probed experimentally by characterizing ionization equilibria of titrating groups, parameterized as pK(a) values. However, pK(a) values of the unfolded state are rarely accessible under native conditions, where the unfolded
Scholarly discourses on energy security have developed in response to initially separate policy agendas such as supply of fuels for armies and transportation, uninterrupted provision of electricity, and ensuring market and investment effectiveness. As a result three distinct perspectives on energy security have emerged: the `sovereignty' perspective with its roots in political science; the `robust
The nitrogen (N) cycle contains two different processes of dissimilatory nitrate (NO(3)(-)) reduction, denitrification and dissimilatory NO(3)(-) reduction to ammonium (DNRA). While there is general agreement that the denitrification process takes place in many soils, the occurrence and importance of DNRA is generally not considered. Two approaches have been used to investigate DNRA in soil, (1) m
It is well known that in the context of the classical regression model with heteroskedastic errors, while ordinary least squares (OLS) is not efficient, the weighted least squares (WLS) and quasi-maximum likelihood (QML) estimators that utilize the information contained in the heteroskedasticity are. In the context of unit root testing with conditional heteroskedasticity, while intuition suggests
Because information about the livelihoods of indigenous groups in Africa is often missing from colonial records, the presence of such people usually escapes attention in quantitative estimates of colonial economic activity. This is nowhere more apparent than in the eighteenth-century Dutch Cape Colony, where the role of the Khoesan in Cape production, despite being frequently acknowledged, has bee
This review describes the use of Pickering emulsions for topical drug delivery. The focus is on Pickering emulsions and how to formulate these. However, a short description of the challenges of topical drug delivery is also given. The article describes how Pickering emulsions might have other properties than traditional topical creams. It is our believe that Pickering emulsions could give added va
This article stresses the significance of recognising interdependencies between factors determining disaster risk in any attempts to integrate disaster risk reduction in international development cooperation. It bases its arguments on the case studies of four past projects in Sri Lanka and Tajikistan, which are scrutinised using a theoretical framework based on systems approaches. It appears that
Mycorrhizal symbiosis involves reciprocal transfer of carbon and nutrients between shoots on the one hand and roots colonized by symbolic fungi on the other. Mycorrhizas may improve the mineral nutrient acquisition rates, but simultaneously increase the belowground demand for carbon. Mycorrhizal plants will have a selective advantage over non-mycorrhizal ones if they are more cost-efficient in ter
The paper compares two lexical items, Icelandic ma@?ur and Swedish man, for the construction of a detached, general discourse stance (Berman, Ragnarsdottir and Stromqvist, 2002). Both forms mean 'man', but they can also be used in a generic sense. In that usage, Icelandic ma@?ur is associated with several semantic, pragmatic, and stylistic constraints, whereas Swedish man is more freely applicable
Background: Few studies have examined how physicians perceive guidelines, much less their perceptions of an Internet presentation of such guidelines. This study assessed physicians' acceptance ofan Internet-based guideline on the appropriateness of colonoscopy. Methods: Gastroenterologists participating in an international observational study consulted an Internet-based guideline for consecutive p
This paper presents an analysis of the Ziegler-Nichols frequency response method for tuning PI controllers, showing that this method has severe limitations. The limitations can be overcome by a simple modification for processes where the time delay is not too short. By a major modification it is possible to obtain new tuning rules that also cover processes that are lag dominated.
Objective: To assess factors for progression in the Early Manifest Glaucoma Trial (EMGT), including the effect of EMGT treatment. Setting/Participants: Two hundred fifty-five open-angle glaucoma patients randomized to argon laser trabeculoplasty plus topical betaxolol or no immediate treatment (129 treated; 126 controls) and followed up every 3 months. Methods: Progression was determined by perime
After 50 years of its prediction, the highest-lying [2 0 2]3/2 orbit among the six Nilsson single-particle orbits originating from the sd shells in prolately deformed nuclei and the rotational band on this orbit were identified. The band members were observed in Al-25 at excitation energies of 6-7.5 MeV in a high-resolution Mg-25(He-3,t) charge-exchange reaction at 0degrees having a strong selecti
Parkinson's disease (PD) is the most common movement disorder. The neuropathology is characterized by the loss of dopamine neurons in the substantia nigra pars compacta. Transplants of fetal/embryonic midbrain tissue have exhibited some beneficial clinical effects in open-label trials. Neural grafting has, however, not become a standard treatment for several reasons. First, the supply of donor cel
In some Wireless Sensor Network (WSN) deployments, nodes may be used for different purposes (sensing, data pre-processing, actuation, etc.). Even if such a network is organised into clusters, this creates heterogeneity in terms of energy capability, which needs to be managed and balanced in order to ensure proper sensing capability with maximised lifespan. In this paper, we present Routing based o
