Dick Harrisson undviker dendrokronologiska dateringar av Lunds äldsta gravar då de inte passar in i hans historiska modell. Som en parallell presenteras de dendrokronologiskt daterade pålar som spärrade Norrström omkring år 1000 vilka stockholmshistorikerna på sin tid inte accepterade.
Under andra världskriget gavs skolan en viktig pedagogisk uppgift för att stärka den ”andliga” beredskapen. Kunskaper ansågs förvisso som viktiga, men av större betydelse var en fostran till självständighet, handlingskraft, fosterlandskärlek och samfundsanda. För att stärka försvarsviljan skulle ungdomar också ges förståelse för vad det innebar att vara medborgare i ett fritt och demokratiskt samh
A previous systematic review has shown associations between exposure to high temperatures and negative birth outcomes. To date, a scoping review for heat indices and their use to measure effects of heat on maternal and perinatal health has not been considered.Objectives To provide a scoping review on heat stress and indices for those interested in the epidemiology and working in extreme heat and m
The study of Paul in the writings of “Hippolytus of Rome” is faced with some particularly difficult methodological challenges. In this chapter, therefore, I wish to do three things. First, I will introduce some of the fundamental problems in Hippolytan research, especially as they relate to the issues of authorship and the nature of the Hippolytan corpus. Second, to mitigate these problems for the
Objective: Alzheimer's disease (AD) and cerebral small vessel disease (cSVD), the two most common causes of dementia, are characterized by white matter (WM) alterations diverging from the physiological changes occurring in healthy aging. Diffusion tensor imaging (DTI) is a valuable tool to quantify WM integrity non-invasively and identify the determinants of such alterations. Here, we investigated
Formation of hydrated magnesium carbonate (HMC) cement phases from the carbonation of brucite has been investigated using synchrotron radiation (SR) based scanning transmission X-ray microscopy (STXM) at Mg and O K-edges. HMC is formed from the reaction of brucite and sodium bicarbonate in water. The introduction of magnesium acetate as a ligand influences the characteristics of the resulting prec
We report on the use of aqueous two-phase systems for the side-chain degradation of cholesterol into androst-4-ene-3,17-dione (AD) and androsta-1,4-diene-3,17-dione (ADD) by Mycobacterium sp. A problem encountered at the start of this investigation, extensive aggregation of the cells, was solved by careful choice of the polymer and detergent composition of the phase system. The systems showing the
We describe a new method for quantitatively measuring substances of clinical interest by high-performance liquid affinity chromatography (HPLAC). As a model system we selected analysis for transferrin in human serum with immobilized antibodies in a high-performance liquid chromatographic system. SelectiSpher-10 Activated Tresyl columns (5 or 10 x 0.5 cm) were used for in situ coupling of polyc
Due to their conceptual appeal and computational convenience, two-level systems (TLSs) and generalizations are used to investigate nonlinear behavior in quantum optics and assess the applicability of theoretical methods. Herein, the focus is on second-harmonic generation (SHG) and, as system of interest, on the Dicke model, which consists of several TLSs inside an optical cavity. The main aspect a
Background: Remaining pain and functional limitations may cause dissatisfaction in patients after total knee arthroplasty (TKA). Furthermore, anxiety and depression are associated with remaining postoperative symptoms and dissatisfaction. We investigated if patient-reported anxiety or depression increased the risk of dissatisfaction 1 year after TKA in patients who improved in pain or function. Me
A new method for preparing chromatographic supports is described. Porous silica was treated with gaseous silanes and gaseous triethylamine at high temperature and reduced pressure. The silylation procedure was rapid and gave supports with a covalently bound monolayer of aminopropyl-or epoxysilane. Diol silica prepared by gas phase silylation was compared with diol silica prepared in the aqueous or
Syftet med den här licentiatuppsatsen är att ur ett universell utformningsperspektiv undersöka vad som kännetecknar dagens återvinningsmiljöer i kommunala bostadsområden och vilka värden som finns kopplade till dessa. De två frågeställningarna är: Vilka normer är framträdande i urvalet återvinningsmiljöer och hur bidrar utformningen till upplevelsen av inkluderande återvinningsmiljöer? Den första The aim of this licentiate thesis is to examine from a universal design perspective whatcharacterizes today's recycling environments in residential areas and what values are linked to them.The first study was carried out at a local level in a recycling environment in a municipality in Norrland.The method used on site was go along-studies and this involved professionals from the municipalrecycling
Severe chronic rhinosinusitis with nasal polyposis (CRSwNP) is a disabling airway disease that significantly impacts patients’ lives through the severity of symptoms, the need for long-term medical treatment and the high risk of recurrence post-surgery. Biological agents targeting type 2 immune responses underlying the pathogenesis of CRSwNP have shown effectiveness in reducing polyp size and eosi
Mycobacterium sp. (NRRL-B 3683) has been immobilized by adhesion of magnetic materials of submicron size to the bacterial surface. Preparations based on laboratory-prepared magnetic oxide that had been derivatized with hydrophobic octyltrichlorosilane showed the best properties. The magnetically immobilized bacteria were used for side-chain degradation of cholesterol into androsta-1,4-diene-3,17-d
The autonomy created for Åland in 1920 along with the linguistic and cultural guarantees stipulated in the 1921 Åland Agreement established Åland as a monolingual Swedish-speaking province within otherwise bilingual Finland. In particular, the Ålandic municipalities could themselves decide whether Finnish was to be taught in their primary schools. One hundred years later, Åland is still monolingua
Objective: The association between work-related moderate-to-vigorous physical activity (MVPA) and higher levels of stress response is recognized, but whether this association is moderated by regular exercise remains unclear. This cross-sectional study investigated whether exercise-based physical activity (PA) associates with lower levels of stress responses moderated by work-related MVPA. Methods:
Introduction: The CVA24 antigenic variant is the causal agent of epidemics of acute hemorrhagic conjunctivitis that has prevailed to date. To study the transmission dynamics and evolution of this variant, we molecularly characterized Cuban isolates obtained in 5 epidemic periods between 1986 and 2009. Methods: Using the BEAST v1.8.4 program, it was performed the phylogenetic and phylodynamic analy
