Abstract This study attempts to understand what problem Isa 53 addresses and seeks to answer. The question is asked as an historical question and it is argued that Isa 53 address a specific historical problem, arising out of the conflicts created after the return of those who had gone into exile. At the end of the exile, there was hope that the deported people would return to the land, that the l
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
Popular Abstract in Swedish Bakgrund och syfte med avhandlingen Glutenintolerans, celiaki är en av de vanligaste kroniska sjukdomarna bland barn och innebär att man inte tåler gluten, som är ett protein och finns i vete, råg och korn. Tunntarmen har en veckad slemhinna med fingerlika utskott , tarmludd och hela tarmen har en yta på 250 kvadratmeter, vilket är lika stort som en tennisplan. Den stBackground: The prevalence of celiac disease (CD) is estimated to be around 1%, but most CD cases are undiagnosed. Sweden experienced an epidemic of clinically detected celiac disease in children younger than 2 years of age, partly due to changes in infant feeding practices, were the amount of gluten and age at introduction was changed. However, it was not clear if the increase in clinically detec
This paper presents a wideband CMOS power amplifier intended for cellular handset applications. The circuit exploits injection locking to achieve a power gain of 20.5dB from a single stage amplifier. The maximum output power of 29dBm, with a peak drain- and power-added-efficiency (PAE) of 66% and 64%, respectively, occurs at a center frequency of 2GHz with a 3V supply. A cross-coupled cascode topo
This paper presents the co-design of a class-D digitally-controlled oscillator (DCO) and a low-dropout voltage regulator (LDO) generating the supply voltage for the DCO. Despite the high intrinsic supply pushing of the class-D oscillator topology, the LDO noise has only a very marginal impact on the DCO phase noise. The class-D DCO and LDO have been integrated in a 65nm CMOS process without any th
Popular Abstract in Swedish Atomspektra har varit ett viktigt forskningsområde inom fysiken sedan mitten av 1800-talet. Då elektromagnetisk strålning, såsom synligt ljus, ultraviolett- och röntgenstrålning, är unik för varje grundämne ger ett observerat spektrum information om vilka slags atomer som emitterar strålningen. Exempelvis så visar spektra av ett vanligt lysrör att ljuset kommer från kviThe spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas. The work details spectroscopic in
The effects of dryer fabric cooling were studied. Using a dryer fabric cooled to a temperature below the dew point of the air-vapour mixture resulted in condensation of water vapour in the fabric structure. This condensation process was studied by means of a small-scale dynamic pilot dryer. The novel model on mass and heat transport in dryer fabrics, described in part 1, was validated against expe
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
Wastewater treatment consists of mechanical, chemical and biological purification. This master thesis concerns the biological part of the wastewater treatment called the activated sludge process (ASP). Two different mathematical models, one simplified and one complete, of the ASP are investigated. The models contain systems of nonlinear partial and ordinary differential equations. The nonlineariti
Ett högspänningsinstrument används för att mäta den dielektriska nedbrytningen av polymera material i syfte att hitta defekter i laminerade kartongförpackningar. Avdelningarna New Material Design och Applied Material Design vid Tetra Pak i Lund ville få förståelse för hur strukturella skillnader i polymera material påverkar materialens dielektriska nedbrytning. De strukturella skillnader som underHigh voltage test equipment is used to measure the dielectric breakdown of polymeric material in order to detect defects in laminated carton based packages. The departments New Material Design and Applied Material Design at Tetra Pak in Lund wanted to understand how structural differences in polymeric material influence the dielectric breakdown of the material. The structural differences investiga
As a social worker you often meet children that are exposed to harmful environments in one way or another. Children who grow up in these circumstances could easily be forgotten, there-fore it is vital that these children are brought to attention. In these situations it´s necessary to find which positiv measures would be benefitial for these children. The internet is an expan-sive resource due to t
The Maha Oya river mouth, located on the west coast of Sri Lanka, is seasonally closed by a sand bar formed at the river mouth due to little rainfall and thus little river discharge. A new Outlet, located just north of the Maha Oya river mouth, was created by the 2004 tsunami. The Outlet remains open all year because of its location in the lee of an offshore breakwater. When the Maha Oya river mou
Evidence-based practice is steadily gaining popularity as the preferred choice of practice within Swedish libraries and the implementation of this practice has been the focal point for several prominent conferences organized and held in Sweden the last couple of years. There seems to be an increasing consensus within the library sphere in Sweden that this is something positive and desirable. Rarel
Human pluripotent stem cell-derived in vitro models, combined with advances in high-content live-cell calcium imaging, provide a powerful platform for disease modeling and drug screening. However, most calcium imaging analysis tools have been developed for in vivo applications with suboptimal features for processing data from cultured neurons. Here, we present LUMIN (Live-cell User Module for Imag
De senaste 100 åren har den globala medeltemperaturen ökat i genomsnitt 0,74 grader, vilket medför stora effekter för såväl människor som djur och natur. En av de största konsekvenserna till den globala uppvärmningen är att den stigande havsnivån blir allt mer påtaglig världen över. Glaciärer och inlandsisar har börjat smälta allt mer, där avsmältningen medför en global ökning i havsnivån. HavsnivThe rising sea level is becoming more evident around the world as less as well as more developed countries are starting to fully comprehend the consequenses. It is also generally accepted that the sea level rise is accelerated by human-induced global warming. Glaciers and ice sheets are melting more and more, which together with temperature induced thermal expansion of the seas which leads to a gl
Most stomatopod crustaceans have complex retinas in their compound eyes, with up to 16 spectral types of photoreceptors, but members of the superfamily Squilloidea have much simpler retinas, thought to contain a single photoreceptor spectral class. In the Atlantic stomatopod Squilla empusa, microspectrophotometry shows that all photoreceptors absorb light maximally at 517 nm, indicating that a sin
