Hägnader har sedan medeltiden varit oumbärliga för hur svenska byar organiserade sin gemensamma betesdrift. Därför har såväl hägnaden som det rättsliga ramverk som strukturerade upp när, var och hur hägnader skulle uppföras, lagen om stängselskyldighet, tillskrivits stor betydelse för bykollektivet i svensk historia. Under 1700- och 1800-talen uppstod dock reformer avsedda att bryta upp detta bykoThe Closed Countryside: The Prescriptive Duty to Fence and the Organisation of Agriculture in Sweden during the 18th and 19th CenturiesThis thesis explores the relationship between fences as enforcing tools and ideas of private property in Sweden during the 18th and 19th centuries. It does this by looking mainly at parliamentary debates about the law on how to manage fences and the peace of the fi

Background: The incidence, aetiology, and outcome of unplanned intensive care unit admission after elective colon cancer surgery remain unclear. This study investigated the incidence of, and factors associated with, unplanned intensive care unit admission following elective colon cancer resection in Sweden. Methods: This nationwide retrospective registry study included adult patients undergoing el

Evidence from neuropathological cohorts indicates that a CSF α-synuclein (α-syn) seed amplification assay (SAA) might provide quantitative kinetic parameters correlating with α-syn pathology burden in patients with Lewy body disease (LBD). Studies are needed to assess their longitudinal trend during the presymptomatic and clinical disease phases and their correlation with measures of disease progr

In Sweden, the adoption of membrane technology for drinking water production is increasing, prompting many water producers to consider substantial investments in new membrane facilities. Ensuring the sustainability of membrane operation in terms of cost,environmental impact, and long-term performance is a top priority. This descriptive study aims to identify common operational trends or practices

Introduction: Antibiotic resistance is rising globally, increasing the demand on new antibacterial substances. Background: Studies suggest that lignin exhibits antibacterial properties, however this property is unexploited commercially. The valorization of lignin is difficult due to its complex and variable structure. Aims: This study aims therefore to fractionate lignosulfonate lignin (LSL) into

Background: Plasma phospholipid fatty acids have been correlated with food intakes in populations with homogeneous dietary patterns. However, few data are available on populations with heterogeneous dietary patterns. Objective: The objective was to investigate whether plasma phospholipid fatty acids are suitable biomarkers of dietary intakes across populations involved in a large European multicen

By investigating both semi-natural and experimentally implemented pH variation in nutrient-poor sandy grasslands, we examined how soil decalcification may influence the arbuscular mycorrhizal (AM) fungal biomass in plant roots and in the soil, as well as the allocation of carbon (C) to AM fungal biomass. We estimated the amount of AM fungal mycelium, by using the fatty acid 16:1 omega 5, in the ro

The use of celestial or geomagnetic orientation cues can lead migratory birds along different migration routes during the migratory journeys, e.g. great circle routes (approximate), geographic or magnetic loxodromes. Orientation cage experiments have indicated that migrating birds are capable of detecting magnetic compass information at high northern latitudes even at very steep angles of inclinat

Background: Previous literature has shown that neighborhood socioeconomic position influences the risk of ischemic heart disease, but little is known about the mechanisms linking the residential context to ischemic heart disease incidence and mortality. We examined whether neighborhood socioeconomic position and neighborhood residential stability (as a determinant of social interaction patterns) h

The morphology and viscoelastic properties of films prepared from bimodal latex blends containing equal weight fractions of soft and hard latex particles were investigated as a function of the particle sizes and the particle size ratio (soft particle diameter/hard particle diameter). Minimum film formation temperature (MFT) measurements were associated with transmission electron microscopy (TEM) t

This thesis deals primarily with the production of written texts by adults with reading and writing difficulties. Their writing is analysed from three different aspects: error analysis, non-error-oriented text analysis and analysis of the production process. These studies are based on data from on-line recordings of writing. The main question is how the written language production of adults with r

Why do certain movements persist over a significant period of time while some do not? How do those that persist sustain themselves and overcome contraints over time, especially those imposed by non-liberal, democratic states? This thesis examines the persistence of a minority social movement, despite facing considerable constraints imposed by a majority-dominated state. Utilizing the Chinese educa

Steady flow and mixing in a model of an "arterialized" vein punctured by a cannula as occurs during hemodialysis has been investigated in vitro. The motivation is that a major cause of vascular access dysfunction is the development of venous stenoses. This phenomenon lacks physiological explanation. However, one may attribute this quick process to the chemical content of the dialyzed blood and its

OBJECTIVE: To study the pharmacodynamics of amoxicillin/clavulanic acid against different strains of Haemophilus influenzae in an in vitro kinetic model. The concentrations used corresponded to human serum levels obtained after 875 mg amoxicillin/clavulanic acid given b.i.d., 500/125 mg amoxicillin/clavulanic acid given t.i.d. and those obtained with a pharmacokinetically enhanced formulation cont

Size distribution measurements performed at five different stations have been investigated during a one-year period between 01 June 2000 and 31 May 2001 with focus on diurnal, seasonal and geographical differences of size distribution properties. The stations involved cover a large geographical area ranging from the Finnish Lapland (67degrees N) down to southern Sweden (56degrees N) in the order V

Background: Few studies have described how neurohormonal activation is influenced by treatment with beta-receptor antagonists in patients with heart failure after acute myocardial infarction. The aims were to describe neurohormonal activity in relation to other variables and to investigate treatment effects of a beta, receptor-antagonist compared to a partial beta, receptor-agonist. Methods: Doubl

The chuck has for a long time been considered the weakest link of a lathe. This is mainly due to its twofold connection, to the machine spindle on the one hand and to the work-piece on the other. An additional limitation of the chuck lies in the incomplete knowledge one has of the load it is exposed to during operation, which usually leads to a less than optimal machining process. Unless our under

It is expected that, in the future, gas turbines will be operated on gaseous fuels currently unutilized. The ability to predict the range of feasible fuels, and the extent to which existing turbines must be modified to accommodate these fuels, rests on the nature of these fuels in the combustion environment. Understanding the combustion behavior is aided by investigation of syngases of similar com
