Taking advantage of the unconventional reactivity of twisted mono- and bis-amides of Tröger's base (TB), rac-6 and rac-7, respectively, the first synthesis of a 6-endo-monosubstituted TB analogue, rac-9, and the first rational synthesis of a 6,12-endo,endo-disubstituted TB analogue, rac-11, have been achieved. The bis-TB crown ether, meso-13, was prepared starting from rac-7. Meso-13 constitutes a
The slope is an important distance parameter for a convolutional code. It can be used to obtain a lower bound on the active burst distance and in this respect essentially determines the error-correcting capability of the code. An upper bound on the slope of rate R = b/c convolutional codes is derived. A new family of convolutional codes, called the maximum slope (MS) code family, is introduced. Ta
We report a case of a patient who suffered generalized urticaria, chest tightness, wheezing, nausea, vomiting, hypotension, and loss of consciousness. Two hours earlier she had taken Eulitop Retard following lunch. She had tolerated all the implicated food after the reaction. Allergy evaluation revealed intense positive responses to intradermal tests with bezafibrate active component and Eulitop R
Background: The tuberculin skin test is used for tracing of tuberculosis transmission and identifying individuals in need of prophylactic treatment. Methods: Using a case-control study design, we recruited 220 smear-positive tuberculosis cases and 223 randomly selected healthy community controls in Bissau, Guinea-Bissau, during 1999-2000. Tuberculin skin tests were performed on family members of c
There is a strong industrial drive to use cloud computing technologies and concepts for providing timing sensitive services in the networking domain since it would provide the means to share the physical resources among multiple users and thus increase the elasticity and reduce the costs. In this work, we develop a mathematical model for user-stateless virtual network functions forming a forwardin
Lately there has been an increasing focus on saving peak power in heating systems as a way to lower the environmental load past just saving energy. At the same time, active cooling is becoming increasingly interesting. Sweden has more and more cooling systems with an increase in cooling also in residential buildings. The cooling power is much more expensive than the heating power. Therefore, there
Background: Omission of prescheduled chemotherapy following surgery for gastric cancer is a frequent clinical problem. This study examined whether laparoscopic gastrectomy (LG) had a positive impact on compliance with adjuvant chemotherapy compared with open (OG). Methods: Patients with cT2-4aN0-3M0 adenocarcinoma treated with gastrectomy and perioperative chemotherapy between 2015 and 2020 were i
Radical cystectomy (RC) for bladder cancer is a complex procedure with an inherent risk of complications and even postoperative mortality. Historically, RC was performed in 44 hospitals in Sweden, which gradually decreased over time, and since a formal regional centralisation of these operations in 2017, cystectomy care is currently provided by nine hospitals. In the Swedish national urinary bladd
We introduce the concept of subalgebra spectrum, Sp(A), for a subalgebra A of finite codimension in K[x]. The spectrum is a finite subset of the underlying field. We also introduce a tool, the characteristic polynomial of A, which has the spectrum as its set of zeroes. The characteristic polynomial can be computed from the generators of A, thus allowing us to find the spectrum of an algebra given
We study left-invariant foliations F on semi-Riemannian Lie groups G generated by a subgroup K. We are interested in such foliations which are conformal and with minimal leaves of codimension two. We classify such foliations F when the subgroup K is one of the important groups SU(2), SL_2(R), SU(2)*SU(2), SU(2)*SL_2(R)$, SU(2)*SO(2), SL_2(R)*SO(2). This way we construct new multi-dimensional famil
The Costa Concordia disaster represents one of the most dramatic ship evacuations of recent years. This thesis constitutes a case study of the Costa Concordia disaster, in an attempt to identify behaviors among the evacuees that may have contributed in reducing the effectiveness of the evacuation procedures. Publicly available material – such as reports from the media, survivor accounts and scient
The rise in entrepreneurial activity over the last 15 years has created space for a nascent industry among the public and private sectors: Business Support Organization (BSO). In the last years, some BSOs have broadened their offer to include for-profit social ventures. Unlike traditional businesses, these ventures try to create a positive social impact while attempting to be economically self-sus
The State of Palestine is drafting a new constitution to replace a patchwork of foreign and outdated legislation, and to harmonise national law with dozens of ratified international treaties. Since its 2012 ascension from non-member observer ‘entity’ to non-member observer ‘state’ in the UN, Palestine has signed fifty-five multilateral treaties covering a wide range of areas. All treaties have bee
Upplevelsen av Malmö är för mig, och för många andra som inte vuxit upp i staden, en ganska grå stad. Kvarter efter kvarter med tegelhus som före detta arbetarbostäder för de stora industrierna. Stadens bild har ändrats mycket under senare tid och efter att ha bott i staden i några år har jag också fått en mer nyanserad bild av hur många olika ansikten staden har - nya platser, hus och miljöer dykThe image of Malmö is to me, and others that hasn’t grown up in the city, a fairly grey story. Blocks after blocks of brick buildings housing the former workers of the great industries that once were the pillars of the city. The face of the city has changed quite radically in recent years and my personal image of the city has been diversified with new places, buildings and environments, which cons
Inom matematiken är det ofta intressant att studera olika strukturer, deras egenskaper, och hur man bäst representerar dem. Så kallade ideal av ringar är ett välstuderat område, men en liknande klass av strukturer kallad subalgebror är hittills mindre studerade. I denna text ges grundläggande definitioner och satser relaterat till LAGBI baser som sedan används för att klassificera vissa polynomsubIn this text, we study almost monomial subalgebras using LAGBI bases. We introduce the concept of a LAGBI base and present an algorithm for computing them. We then use this algorithm to find, and present in a table, all polynomial subalgebras with Frobenius number smaller than or equal to ten. We then prove that some patterns observed in this table hold. Lastly we give a proof of what properties i
Den globala uppvärmningen förändrar jordens klimat i snabb takt, det är främst utsläpp av växthusgaser som exempelvis koldioxid från förbränning av fossila bränslen som är orsaken. Sverige har tagit flera steg mot en hållbar energiproduktion där 65 % av elen är förnybar, men samtidigt är fossila bränslen en betydande del. Av Sveriges totala energianvändning går 25 % till att värma upp det befintliGlobal warming is changing the Earth's climate and is mainly caused by greenhouse gas emissions from, for example, fossil fuels. Sweden's energy production consists of 65 % renewable energy, but the remaining amount comes from fossil fuels. Of Sweden's total energy production, a quarter goes to heating existing buildings. Upcoming EU directives set higher requirements for energy effici
Många företag idag vill göra simuleringar i en dator innan de börjar bygga fysiska prototyper. Fördelen med detta är att det är billigare att simulera produkter än att bygga prototyper, och det går snabbare att göra ändringar.For the modeling language Modelica, there is no standard for the testing of Modelica models. In this thesis we investigate a new way to create and run tests by developing an external test authoring tool. Our tool was developed by first examining existing testing practices, and then trying to improve upon those by iteratively developing our tool. This was done while continuously performing user stu
Power amplifiers play a crucial role in wireless communication systems. However, they can achieve high efficiency only when operating in the nonlinear region. To maintain linear output while operating in this region, several techniques have been developed, among which digital pre-distortion (DPD) is one of the most widely used. In this thesis, we designed and analyzed a digital predistortion (DPD)
Purpose: Nurses constitute a key group to focus on due to their close proximity to the core of health care, the patient. We aim to understand the care discourse in the practice of nursing within public health care organizations, and its coexistence with the current marketization discourse promoted by the New Public Management paradigm. Our intention with this approach is not only to nuance and pro
The importance of design in order to accentuate a market position becomes increasingly important in the commercial vehicle sector. As a result, the company leading the pack in terms of design and styling is facing immense imitation from western competitors as well as commercial vehicle manufacturers from emerging markets. In response, the company has adopted a strategy of using design protection o
