The effect of reaction temperature, water content, and vanadia content on the sintering of a model vanadia on silica-titania SCR catalysts has been investigated. A comparison is also made to a monolithic vanadia/titania catalyst submitted to conditions simulating at least 500,000 km driving on a diesel truck. The variation of the surface area, the pore structure and the crystallite size of the cat
Institutional theory of the firm focuses on firm boundaries and the activities firms internalize within their hierarchies. However, an examination of disintegrated firms that influences activities beyond the scope of their hierarchies suggests that firms also perform other economic functions. By analysing these functions, the aim of this paper is to suggest a theory of the firm that goes beyond in
We establish a new mechanism for self-propelled motion of droplets, in which ordering of the nanoscale step morphology by sublimation beneath the droplets themselves acts to drive them perpendicular and up the surface steps. The mechanism is demonstrated and explored for Ga droplets on GaP(111)B, using several experimental techniques allowing studies of the structure and dynamics from micrometers
The reassignment technique is used to increase localization for signal components in the time-frequency representation. The technique gives perfect localization for infinite linear chirp-signals, impulses and constant frequency signals but not for short non-stationary signals. In this paper, a scaled reassignment is proposed, based on the spectrogram using a Gaussian window. The resulting reassign
This paper presents a framework for policies development enabling growth of Nearshore in information and communications technologies (ICT) services inside European Community (EC), which are based in Portuguese companies, emphasizing what is needed to explore the huge opportunity to develop exportations, employability and the national economy. In a market of ICTs Outsourcing services forecasted in
We report on methods capable of measuring a rms vertical electron beam size of 3 pm with a runs error of less than 10% at a diagnostic beamline at the Swiss Light Source (SLS). This corresponds to a vertical emittance 01 06 pm rad with a 20% rms error. We showed this capability by presenting the theoretical basis for, and the data from, a series of measurements on a stable beam at 1.6 pm rad verti
Changes of the electronic structure accompanied by charge localization and a transition to an antiferromagnetic ground state were observed in the organic semiconductor (DOEO)(4)[HgBr4]center dot TCE. Localization starts in the temperature region of about 150 K and the antiferromagnetic state occurs below 60 K. The magnetic moment of the crystal contains contributions of inclusions (droplets), and
OBJECTIVE: To assess the outcome of vacuum-assisted wound closure (VAC(®)) therapy for infected bypass grafts. METHODS: A retrospective 7-year review of patient records from 2004 to 2011 of all patients receiving VAC(®) therapy for infected bypass grafts. RESULTS: Thirty-seven patients with 42 wounds and 45 infected bypass (28 synthetic) grafts received VAC(®) treatment. Two serious bleeding e
Due to the multiple benefits of biogas systems, the Chinese Government has made great efforts to promote the development of biogas systems in rural China, especially household biogas plants and medium and large scale biogas plants to treat manure and waste water from intensive livestock and poultry farms. This thesis conducts a comprehensive literature review to understand the current situation of
The recent events of piracy, especially in the Gulf of Aden raised the concerns of the international community, shipping businesses as well as the marine insurance industries. The drastic increase in piratical incidents and the costs associated with them started a discussion as to the piracy coverage under modern marine insurance policies. Piracy has oscillated through history between being treate
Nynas Petroleum is one of the world´s largest producers of naphthenic specialty oils. They have refineries in several parts of the world and their largest production facility is situated in Nynäshamn, Sweden. They also have oil depots in all continents and their largest depot is located in Antwerp, Belgium. In the beginning of 2007 Nynas introduced a new type of transformer oils, called Nova grade
Today’s marketplace is increasingly growing more competitive as production accelerates and products multiply. Therefore, competing organizations have shifted their focus from solely developing the best product, to building value and competitiveness into the employees. As a result, the concept ‘Employee Engagement’ has received a lot of attention during the 21th century. However there still remain
A Poisson integral formula for a weighted Laplacian in the unit disc Beskrivning: In this paper a counterpart of the classical Poisson integral formula is found for a weighted Laplace differential operator in the unit disc. In the process the corresponding Dirichlet boundary value problem is solved for arbitrary continuous boundary data. The associated power series expansions are calculated and in
The logistics concepts at BMW's engine factory in Munich are continuously revised, in order to optimise the logistics process. The objective of this thesis work is to study if it would be profitable to use an individual, reusable package for transporting and handling engine wiring harnesses in order to prevent damages. Approach The work was divided into different stages. First the flow of th
Amid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita
In recent years, scientists have found unconfirmed evidence for a ninth planet in the solar system at a very wide orbit. The parameters for this planet are poorly constrained. Current estimates mostly come from the effect the planet has on trans-neptunian objects. Here we investigate an alternative scenario, that is whether this proposed planet can exert observable perturbation on Main Belt astero
In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. This thesis introduces a linear algebra framework for closed orbit perturbation and correction, its implementation as a Python package and its use for three studies in HL--LHC: orbit corrector bu
To develop treatments for currently uncurable neurological disorders, more knowledge is needed of the involved neural circuits and changes in gene expression. The padlock probe technique, in which linear DNA probes are circularized and amplified when hybridized to their cDNA target sequence, has previously been used for both multiplexed gene detection and neuronal projection mapping in brain tissu
