A stirred tank membrane reactor is used to study the kinetics of polygalacturonic acid (PGA) enzymatic hydrolysis. The reactor operates in semicontinuous configuration: the native biopolymer is loaded at the initial time and the system is continuously fed with the buffer. The effect of retention time (from 10 1 to 142 min) and membrane molecular weight cutoff (from I to 30 kDa) on the rate of perm
As a result of the reorganization of Lund Institute of Technology at Lund University, the new Department of Design Sciences was established. In focus of the establishment of this Department was the ambition to facilitate cross-disciplinary research within the design area. The project presented here is one of the first results of this ambition. In this project the overall objective is the increase
We present the complete automation of the computation of one-loop QCD corrections, including UV renormalization, to an arbitrary scattering process in the Standard Model. This is achieved by embedding the OPP integrand reduction technique, as implemented in CutTools, into the MadGraph framework. By interfacing the tool so constructed, which we dub MadLoop, with MadFKS, the fully automatic computat
High-order harmonics generated through the interaction of atoms and strong laser fields are a versatile, laboratory-scale source of extreme ultraviolet (XUV) radiation on a femtosecond or even attosecond time-scale. In order to be a useful experimental tool, however, this radiation has to be well characterized, both temporally and spectrally. In this paper we discuss how multi-photon, multi-colour
This contribution presents a modeling and optimization method for multi-column counter-current purification (MCSGP) processes. The model is based on conventional column models and by using the symmetric and cyclic steady state characteristics of the process a single column analog model was developed. The model have been used for dynamic optimization of the MCSGP process. The optimization was based
Europeans have tried for decades to find a way to take a mutual stance on issues of higher education and its development. In terms of taking on the challenge of such a mutual commitment with respect to higher education, the Bologna process is a giant step for the European Union. It involves a large number of countries, representing a great variety of higher education systems, which are currently e
The relay autotuner for PID control is based on the simple idea of investigating process dynamics by the oscillation obtained when the PID controller is replaced by a relay unction. In this paper an asymmetric relay function is used, which provides an equation for the static gain of the process. A method to find the normalized time delay is proposed and the benefits of this is discussed. Ways to f
In this article we report on how 64 dentists working in a big city in southern Sweden view their profession. The dentists ranged in age from 30 to 70 years (as it was indicated in intervals of 10 years). Their professional experience ranged from 2 to 44 years (mean, 23 years). We collected their views on the ideal skills of a good dentist by means of a questionnaire. From this material we identifi
Inom området för tvistelösning, har skiljedom genom historien blivit ett allt populärare alternativ till rättstvistprocessen. De viktigaste inslagen i skiljedom ger avtalsparterna med många fördelar såsom diskretion, effektivitet och lägre kostnader, genom att göra det smidigare i ett antal olika forum och branscher där dessa aspekter är avgörande. Dessutom kan skiljedomsförfarandet erbjuda avtalsIn the world of dispute resolution, arbitration has throughout history been an increasingly popular alternative to the litigation process. The major features of arbitration provide contracting parties with many advantages such as discreetness, efficiency and lower costs; making it preferable in a various number of branches and industries where such features are crucial. Furthermore, the arbitratio
This paper investigates whether inflation series are mean-reverting. Traditional unit root tests (ADF and KPSS tests) are conducted in the paper. These tests indicate that inflation contains a unit root. It is however well-known that traditional unit root tests have difficulties to distinguish between a unit root process and a fractionally integrated process. Hence, in this thesis, fractional inte
Nutrient sensors that can be located directly in the activated sludge processes are gaining in number at wastewater treatment plants. The in situ location of the sensors means that they can be located close to the processes that they aim to control and hence are perfectly suited for automatic process control. Compared to the location of automatic analysers in the effluent from the sedimentation re
Issue of study: In decentralised companies, products that are not in the central assortment, but still sold by the subsidiaries are known as local assortment. Understanding the reasons to why local assortment exists is important for the companies to ensure compliance. To have products that comply with laws and regulations are especially vital in the agricultural industry, due to its large personal
Konceptet city branding har växt fram som ett strategiskt verktyg i syfte att uppnå positiva uppfattningar av en stad bland invånarna samt attrahera de som vill bosätta sig på, investera i eller besöka platsen. Evenemang och festivaler har visat sig vara populära strategier ämnade att skapa mervärde i värdstadens samhälls- skikt, som bidrar till det varumärke och den image som önskas. Malmö är enThe concept of city branding has emerged as a strategic tool in order to achieve positive perceptions of a city among residents and to attract those who want to live, invest or visit the location. Events and festivals have proven popular strate- gies in order to create added value in all societal aspects of the host-city, contrib- uting to the brand and image as desired. Malmö is a multidimensiona
The purpose of this study was to further investigate whether the national funda-mental values have been implemented in the different municipalities’ goals for the elderly care and how this was followed-up and evaluated, in order to achieve a deepened knowledge of how the different municipalities worked with their own quality assurance within this particular field of practice. In order to answer ou
