Rapid and reliable observations of soil electrical conductivity are essential in order to maintain sustainable irrigated agriculture. Direct measurement of the electrical conductivity of saturated soil paste (ECe), however, is tedious andtime consuming. Therefore, there are needs to find efficient indirect methods to predict the soil salinity from other readily available observations. In this pape
The anaerobic bacterium Finegoldia magna is part of the human commensal microbiota, but is also an important opportunistic pathogen. This bacterium expresses a subtilisin-like serine-proteinase, SufA, which partially degrade the antibacterial chemokine MIG/CXCL9. Here, we show that MIG/CXCL9 is produced by human keratinocytes in response to inflammatory stimuli. In contrast to the virulent human p
The observation that neural grafts can induce dyskinesias has severely hindered the development of a transplantation therapy for Parkinson's disease (PD). We addressed the hypothesis that inflammatory responses within and around an intrastriatal graft containing dopamine neurons can trigger dyskinetic behaviors. We subjected rats to unilateral nigrostriatal lesions with 6-hydroxydopamine (6-OHDA)
This PhD thesis is made up of five independent studies and a comprehensive synthesis. The first three studies are published 2001 in the book Vem behöver en by? Kyrkheddinge, struktur och strategi under tusen år (pp. 1-95) (Who needs a village? Kyrkheddinge, Structure and Strategy During a Thousand Years). The remaining two parts and the synthesis are published in the volume Den medeltida byns soci
Aims: Respondent-driven sampling is a research technique, new to the Scandinavian setting, used in hard-to-reach populations, such as subjects at risk for HIV, including drug users. This study aimed to evaluate the use of respondent-driven sampling originating from syringe exchange clients, as a method to identify 'hidden' drug users without treatment or social service contact. Methods: Nine heroi
Popular Abstract in English Fruits are a key complement to the diet of many people in the southern region of Africa, especially in rural areas. maphilwa (Vangueria infausta L.), maçanica (Ziziphus mauritiana), maçala (Strychnos spinosa), mapsincha (Salacia kraussi), cajú (Anacardium accidentale L.), mavungwa (Landolpia kirki) are some of the most commonly found fruits in sub-Saharan Africa, particThis study concerns the identification and characterisation of volatile components of fruits, and evaluation of the effect of heat treatment and drying on retention or loss of volatiles of fruits. The investigation included developing a procedure to extract volatile components from the fruit matrix, a purification step, separation, identification and quantification. Initial experiments with Vangue
In 2008 the Commission for the Legal Empowerment of the Poor, CLEP, put forward a grand policy proposition claiming that comprehensive legal, political, social and economic reforms whereby the poor are legally empowered can put an end to perpetuating poverty in developing countries. A well functioning rule of law is considered the foundation on which all institutional structures promoting economic
Popular Abstract in Swedish Lunds strängfragmenteringsmodell beskriver hur färgade partiklar (kvarkar och gluoner, tillsammans kallade partoner) som produceras vid högenergetisk partikelkollisioner omvandlas till färgneutrala hadroner. Denna avhandling utvecklar och utforskar ett alternativt tillvägagångssätt till modellen. Den nya infallsvinkeln förbättrar modellen för system som består av många
Popular Abstract in English Prostate cancer is one of the most common causes of death for men. This disease can be detected at different stages and if it is detected at an initial stage there are many therapies to choose from. However, if it is detected at an advanced stage the options are reduced and most of the treatments are aggressive in an effort to extend the patient’s life. The most common In search for remedies and treatments, science has recurred to Mother Nature. This is where galiellalactone was found, a fungal metabolite isolated from Galiella rufa in 1990. Since then chemists and biologists have been studying its properties and found it to be a potential candidate against castration-resistance prostate cancer (CRPC). The development of a new drug requires many studies of the c
Popular Abstract in Swedish Jäst kan antingen bryta ner socker direkt till koldioxid och vatten genom andning, eller indirekt via koldioxid och etanol, genom jäsning. Andning är en process som förbrukar syre, och sker därför endast under syrerika (aeroba) förhållanden. Jäsning kräver till skillnad från andning inte tillgång till syre, och kan därför ske under syrefattiga (anaeroba) förhållanden. Under aerobic conditions, most yeasts such as Kluyveromyces lactis, prefer the respiratory pathway and some, such as Saccharomyces cerevisiae prefer less energy efficient fermentative pathway for their energy metabolism. These two metabolic strategies are also known as Crabtree negative and Crabtree positive respectively, and the evolution of the latter has lately been explained by the “make-accum
Auto-ignition with SI-compression ratio can be achieved by replacing some of the fresh charge by hot residuals. In this work an engine is run with a negative valve overlap (NVO) trapping hot residuals. By increasing the NVO, thus raising the initial charge temperature it is possible to investigate the intermediate zone between SI and HCCI as the amount of residuals is increased. Recent research ha
Transitional care for adolescents with congenital malformations, such as anorectal malformations (ARM), is described sparsely in the literature and referred to as being inadequate. In order to organize future successful healthcare structures, knowledge of patient-reported important aspects of transition is required. The aim of the study was therefore to explore the needs and expectations of transi
Increasing temperature trends are expected to impact yields of major field crops by affecting various plant processes, such as phenology, growth, and evapotranspiration. However, future projections typically do not consider the effects of agronomic adaptation in farming practices. We use an ensemble of seven Global Gridded Crop Models to quantify the impacts and adaptation potential of field crops
SUMMARY: Antibody repertoires reveal insights into the biology of the adaptive immune system and empower diagnostics and therapeutics. There are currently multiple tools available for the annotation of antibody sequences. All downstream analyses such as choosing lead drug candidates depend on the correct annotation of these sequences; however, a thorough comparison of the performance of these tool
The compelling images and promises attached to autonomous drive vehicles can easily create an impression that one can speak of a radical distinction between a self-driving future and a manual-driving present. Yet today’s drivers can already refer to their everyday driving as being experienced as though on ‘auto-pilot’, in which they are able to drive their cars while lost in things such as daydrea
Water resources are under increasing pressure, and there are tensions between increasing demand and the natural limits to potable water supply. Authorities must find solutions that fulfil societal demands without compromising environmental integrity. As one way to counteract water deficits, desalination has evolved as an attractive solution. This technology is contested and associated with a varie
Background: Data commentary, in-text comments on the visual presentation of data, is acknowledged as a central aspect of academic writing in many engineering disciplines. At the same time, it is a feature that it has been shown to be challenging for students. One of the genres in which data commentary plays a significant role in many engineering disciplines is the master’s thesis. Comparatively li
The impact of sample crushing on the detected porosity of hardened cement pastes by low temperature calorimetry (LTC) was studied using powder and cylinder samples. Two types of cements, CEM I and CEM III were used to prepare the pastes. A model porous material, MCM-41, was also used in order to investigate some aspects of the measurement and the evaluation approach. The powder and cylinder sample
Basidiomycota fungi in the order Polyporales are specified to decomposition of dead wood and woody debris and thereby are crucial players in the degradation of organic matter and cycling of carbon in the forest ecosystems. Polyporales wood-decaying species comprise both white rot and brown rot fungi, based on their mode of wood decay. While the white rot fungi are able to attack and decompose all
