En grundvattenundersökning i ett område präglat av vattenrelaterade problem. Staden Cochabamba i Bolivia står inför flera vattenrelaterade utmaningar såsom brist på ytvatten, en ökande vattenanvändning, urbanisering och en sjunkande grundvattennivå. Samtidigt råder det en brist på kunskap angående de processer som påverkar grundvattnet i området. Något som detta examensarbete ämnar att förändra. The Central Valley of Cochabamba is located in the Andes mountain range, Bolivia. This region experiences several water related challenges such as a scarcity of surface water, an increasing water demand, a growing urbanization in groundwater recharge areas, and a declining water table due to intensive groundwater extraction. The valley has been influenced by both alluvial and fluvial depositions t

Background: Subgroups of adult-onset diabetes, namely severe autoimmune diabetes (SAID), severe insulin-deficient diabetes (SIDD), severe insulin-resistant diabetes (SIRD), and mild obesity-related diabetes (MOD) or mild age-related (MARD) diabetes, have been defined with clinical variables and a machine-learning approach. Our aim was to describe their long-term outcomes and mortality. Methods: In

Background The dura mater has a permeable vasculature similar to that of peripheral organs, and is separated from the brain, which is enclosed within the arachnoid barrier. Fluid and solute transport across the arachnoid barrier between the subarachnoid space (SAS) and dura is crucial for brain waste clearance and immune surveillance, but few neuroimaging approaches can capture this dynamic proces

Extraterrestrial cratering was a critical component in the evolution of the early Earth, but discovery of very ancient and deeply exhumed impact structures remains elusive, as identification tools are in short supply. The recognition of such structures is hindered by post-cratering geological processes, whereby impact-induced features common in younger, upper-crustal craters may be lost. In this s

Fog makes a significant contribution to the hydrology of a wide range of important terrestrial ecosystems. The amount and frequency of fog immersion are affected by rapid ongoing anthropogenic changes but the impacts of these changes remain relatively poorly understood compared with changes in rainfall. Here, we present the design and performance of a novel experiment to actively manipulate low ly

High-Arctic environments are facing an elevated pace of warming and increasing human activities, making them more susceptible to the introduction and spread of alien species. We investigated the role of human disturbance in facilitating the spread of a native plant (Papaver dahlianum) in a high-Arctic natural environment close to Isfjord Radio station and along adjacent hiking trails at Kapp Linné

Clinical trials of pharmaceuticals have been running in Russia for more than ten years and while it is an attractive location for research, it remains a largely untapped resource as researchers look to expand patient recruitment outside the Western world. While academic sites like Moscow, St Petersburg and Novosibirsk have all gained experience in clinical trials, smaller hospitals in peripheral

We have developed the novel Aerosol Dynamics, gas- and particle-phase chemistry model for laboratory CHAMber studies (ADCHAM). The model combines the detailed gas-phase Master Chemical Mechanism version 3.2 (MCMv3.2), an aerosol dynamics and particle-phase chemistry module (which considers acid-catalysed oligomerization, heterogeneous oxidation reactions in the particle phase and non-ideal interac

The success of social movements is highly dependent on their sustainability, as in their efforts to produce meaningful change, they inevitably encounter oppressive dominant forces. With the advent of the social media era, scholarly research on collective action has acquired an additional dimension, bringing the role of their communicative constitution to the forefront of discussions. However, a de

Popular Abstract in Swedish Varför beslutar politiker ibland att vidta till synes effektlösa åtgärder? Varför uppstår ibland stora politiska konflikter i små frågor? I vanliga fall vidtar man en politisk åtgärd därför att man eftersträvar det konkreta resultatet av åtgärden. Symbolpolitik är när en politisk fråga blir viktig, inte beroende på vad den konkret innebär och leder till, utan på grund aSymbolic politics is the degree to which political decision-making is motivated, not by the tangible aspects of the decision, but by the interpretation of what the decision represents symbolically. While symbolic politics is widely recognized as an important aspect of political decision-making, the phenomenon is insufficiently explored in political science. The first aim of the present dissertatio

Premise: Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia. Methods: We measured floral traits, reflectance of petals and nectar-guide

Popular Abstract in Swedish De allra flesta människor har vid något tillfälle tagit ett läkemedel. Till exempel vaccineras nu för tiden alla svenska barn mot bland annat stelkramp. Vad nog de allra flesta däremot inte har gjort är att fundera på vad ett läkemedel är. Kanske sträcker man sig till att ha kollat upp ett läkemedel i FASS, och kanske får man då syn på en figur som består av streck och A method to accurately estimate the binding affinity of a small molecule to a receptor would be indispensable in numerous fields. For instance, most drugs exert their action by binding to a macromolecule target. Thus, a lot of time and resources could be saved in drug design by predicting affinities by computer programs. In a series of 15 papers, we have tested, compared, and improved the most p

The beach topography change in the nearshore zone may be induced by natural phenomena such as wind, wave, storm, tsunami, and sea level rise. However, it can also be caused by man-made structures and activities, for example, groins, detached breakwaters, seawalls, dredging, and beach nourishment. Therefore, understanding the beach topography evolution in this zone is necessary and important for co

Popular Abstract in Swedish Syftet med denna avhandling var att undersöka olika aspekter på intersubjektivitet, metakognitiv utveckling och mellanmänsklig förståelse. Mer precist var syftet att undersöka hur några specifika teorier – mentaliseringsteorin, teorin om primär intersubjektivitet, samt interaktionsteorin – beskriver vilken roll intersubjektivitet har att spela i denna utveckling. De förThe aim of the thesis was to examine different aspects of the role of intersubjectivity in metacognitive development and in social understanding. More specifically, it investigates how different theoretical frameworks, such as mentalization theory, the theory of primary intersubjectivity, and interaction theory describe the developmental role of intersubjectivity. The suggestions these theories ma

Popular Abstract in Swedish Polymermembranbränsleceller (PEM) anses vara en mycket lovande teknik inom fordonsindustrin på grund av dess kompakthet i storlek, höga verkningsgrader samt låga arbetstryck och temperaturer.

It consists of one introductory chapter and three independent papers relating to determinants of firms’ exporting. Chapter 2 investigates the distance effect on the exporting of homogeneous and diff

Popular Abstract in Swedish Denna rättssociologiska studie handlar om tvångsomhändertagna missbrukares rättssäkerhet under tiden i vård. Författaren undersöker begreppet rättssäkerhet i förhållande till tvångsvårdens verkställighet på så kallade LVM-hem i syfte att finna en begreppsdefinition som är operationaliserbar vid studier av rättssäkerhetens upprätthållande. Med utgångspunkt i resultaten Compulsory treatment and care is regulated by the Care of Alcoholics and Drug abusers Act (Lag (1988:870) om vård av missbrukare i vissa fall, LVM). The regulation's main purpose is to motivate persons with addictive problems to voluntarily participate in the treatment of their problems. The compulsory care shall continue for a maximum period of six months in special treatment centres (the so-call

Popular Abstract in Swedish Vid tillagning av kött, och framför allt stekning och grillning, bildas mutagena ämnen i stekskorpan. Dessa ämnen benämns heterocykliska aminer. Flera epidemiologiska studier har visat ett samband mellan uppkomsten av cancer och intaget av heterocykliska aminer, medan några studier inte finner något samband. Ämnena har också visat kunna utveckla tumörer och cancer i djuCommonly cooked meat dishes contain heterocyclic amines (HAs) at ng/g levels. HAs are animal carcinogens, form DNA adducts in human tissues, and have been associated with increased risk of cancer in epidemiological studies, and it is thus recommended that human intake be decreased. The aim of this investigation was to find ways of modifying cooking practices to reduce the formation of HAs. Various

Popular Abstract in Swedish Lysande plast, finns det? Tanken är att att tunn plast-film skall kunna användas som ihoprullbara tunna TV- och datorskärmar, som lysdioder, som mottagare i solceller och som transistorer. Till vardags är förmodligen den vanligaste uppfattningen att plast är ett isolerande material som inte leder ström och som därför heller inte lyser. Faktum är att bara en del av plasTransient absorption laser spectroscopy and resonance Raman spectrscopy have been used to study conjugated polymers and oligomers. To extract more information the measurements have been compared to computer simulations and calculations. In order to obtain a better understanding of the role of conformational disorder in the photophysics of light-emitting, conjugated polymers the ultrafast transient
