A metal nanoparticle can be considered as consisting of a base of positive ion cores and a sea of free electrons. When the free electrons are displaced, for example, by an incident electric field, a restoring force acts on the electrons. The electrons may then oscillate back and forth until equilibrium is reached. This oscillation occurs at the natural frequency, or eigenfrequency, of the system.
The meaning of the notion of value, as well as associated concepts such as value creation and value appropriation, has been subject to much confusion in marketing and management.This article builds on a rich tradition in economics to untangle some of the ambiguities surrounding these concepts. First, it is argued that a rigorous approach to analyzing value must be based on a subjectivist notion of

The meiotic functions of Emi2, an inhibitor of the APC/C complex, have been best characterized in oocytes where it mediates metaphase II arrest as a component of the cytostatic factor. We generated knockout mice to determine the in vivo functions of Emi2—in particular, its functions in the testis, where Emi2 is expressed at high levels. Male and female Emi2 knockout mice are viable but sterile, in
The role of accountants in organizations is intriguing in the current context of the broad changes in the profession observed by many. Mainly because of technological advancements, what has previously required a considerable amount of time and effort, i.e. bookkeeping & reporting, has been assumed to ‘just happen’ easily, with a corollary that it should not be taken for granted, that the accou
Perlecan is a heparansulfate proteoglycan found in basement membranes, cartilage, and several mesenchymal tissues that form during development, tumour growth, and tissue repair. Loss-of-function mutations in the perlecan gene in mice are associated with embryonic lethality caused primarily by cardiac abnormalities probably due to hemopericards. The aim of the present study was to investigate the m
Neurocan is a component of the extracellular matrix in brain. Due to its inhibition of neuronal adhesion and outgrowth in vitro and its expression pattern in vivo it was suggested to play an important role in axon guidance and neurite growth. To study the role of neurocan in brain development we generated neurocan-deficient mice by targeted disruption of the neurocan gene. These mice are viable an
Title: Is the Honeymoon Over For Instagram? - A qualitative study on how Generation Y reasons about brand marketing strategies Purpose: The purpose of this thesis is to investigate how Instagram-users from Generation Y reason about various forms of marketing on Instagram, in order to contribute with a deeper understanding on how they view brand strategies to reach them as consumers. Theoretical
The purpose of this thesis is to gain an understanding of the credibility gap between consumers and marketing strategies that aims at gaining moral legitimacy by taking a stand, since it is becoming increasingly important for companies to gain moral legitimacy. By triangulating theories within consumer culture theory, corporate social responsibility and organizational legitimacy and conducting a q
Denmark is currently undertaking extensive groundwater mapping surveys in designated water interest areas. The mapping objectives include vulnerability assessments, delineation of existing aquifers, and localization of new deeper lying aquifers. Airborne electromagnetics are employed for regional mapping to depths of hundreds of meters. Resistivity profiling and pulled-array geo-electrics are util
Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide
It is obviously expected that sustainable development is the primary target to raise prosperity and life standards of nations. It is necessary to ensure social, political, and economic stability. But what about the stimulus factors that motivate sustainable development? Can income inequality be one of them? Some literature has examined the role of income distribution on economic growth, but to te
