The main objective of this thesis is to investigate the distribution of hydrological resources over time and space in two sub basins of the Lake Poopó area in Bolivia. This investigation is made in order to evaluate how supply and demand can be balanced and what effect the insufficiency of hydrological resources has on the socio economic situation. The two main problems in the area regarding water
ABSTRACT TITLE: Oil price shocks impact on the British and the Swedish stock markets SEMINAR DATE: 2007-06-07 COURSE: Bachelor thesis in Business Administration and Economics, 10 Swedish credits (15 ECTS) AUTHORS: Carl Hersaeus, Sven Piehl Trygg ADVISORS: Hossein Asgharian, Göran Andersson KEY WORDS: Dummy Variables, United Kingdom, Oil Price, OLS, Regressions, Stock Markets, and Sweden PURPOSE: T
We investigate various performance indicators of ten leading journals in the field of Agricultural Economics and Policy over the period from 2000 to 2020. More specifically, we combine various data sources to derive a coherent record of indicators including acceptance rates, times between submission and first response and impact factors. We show that, for the discipline at large, the turn-around t
Motivation: Dynamical models describing intracellular phenomena are increasing in size and complexity as more information is obtained from experiments. These models are often over-parameterized with respect to the quantitative data used for parameter estimation, resulting in uncertainty in the individual parameter estimates as well as in the predictions made from the model. Here we combine Bayesia
Type specimens of Sympycnus pulicarius, S. annulipes, S. cinerellus and S. desoutteri were examined to clear up a long-lasting taxonomic confusion. Our study revealed that they represent, together with S. pygmaeus and S. annulipes var. brunnitibialis, a single species, with S. pulicarius as the senior subjective synonym, which is redescribed in this paper. Lectotypes were designated for Dolichopus
Insulin resistance causes compensatory insulin production, which in humans can eventually progress to β-cell failure and type 2 diabetes (T2D). This disease progression involves multi-scale processes, ranging from intracellular signaling to organ and whole-body level regulations, on timescales from minutes to years. T2D progression is commonly studied using overfed and genetically modified rodents
Maritime archaeological investigations of the wreck of the medieval warship Gribshunden (1495), flagship of King Hans of Denmark and Norway, have revealed diverse artifacts including exotic spices imported from far distant origins: saffron, ginger, clove, peppercorns, and almond. The special circumstances of the vessel's last voyage add unique context to the assemblage. Gribshunden and an accompan
Popular Abstract in Swedish Beständiga organiska miljögifter, till exempel PCB (Polyklorerade bifenyler), har vållat stora miljöproblem i flera decennier. Dessa föroreningar är kemiskt och biologiskt sett väldigt stabila, vilket gör att de bryts ner mycket långsamt i miljön och alltså kan transporteras långväga med vindar och strömmar. Därför kan man hitta PCB över hela jorden, även i områden där Persistent organic pollutants (POPs) pose serious threats to our global environment. These compounds have high chemical and biological stability and they are also very lipophilic. These characteristics not only render POPs the ability to spread widely and pollute remote areas, they also make them prone to accumulate in adipose tissues of living organisms. Consequently, it is important to monitor P
The use of vectoring for crosstalk cancellation in the new ITU-T G.fast standard for next generation DSL systems becomes essential for efficient utilization of the extended bandwidth (up to 200 MHz). In VDSL2 (up to 30 MHz), a zero-forcing-based linear precoder is used in downstream which approaches single-line performance. However, at high frequencies, the linear precoder may amplify the signal p
Resources within and between higher education and research institutions are increasingly allocated according to scientific performance. Evaluation exercises and the measurement of research performance take on a new role in this context. Third party research income is a performance indicator which is rather easy to measure and is used in most of the new performance-based evaluation procedures. This
The free volume changes of poly[1-(trimethyl-silyl)-1-propyne] (PTMSP) treated in supercritical CO2 (scCO(2)) were investigated with positron annihilation lifetime spectroscopy (PALS). CO2 is known to plasticize and increase the free volume size of a broad range of polymers. In this work dense PTMSP films were treated with scCO(2) under different pressures and temperatures, resulting in the enlarg
Background To account for differences in body size in patients with aortic stenosis, aortic valve area (AVA) is divided by body surface area (BSA) to calculate indexed AVA (AVA(index)). Cut-off values for severe stenosis are <1.0cm(2) for AVA and <0.6cm(2)/m(2) for AVA(index). Objective To investigate the influence of indexation on the prevalence of severe aortic stenosis and on the predictive acc
Islands allure imagination, thought and affect. Imagination, thought and affect conjure islands. Literary imaginations create islands more than any other geographical form. Metaphorically, we use concepts of bounded and contained islands to think with, to an extent not commonly recognized. Emotions and desires are moved by and commonly move us towards or away from islands. Relatedly, in a deeper t
Popular Abstract in Swedish De fettlösliga vitaminerna upptäcktes i början av 1900 talet, och indelas i klasserna A, D, E och K. Brist på vitaminer i kroppen kan leda till svåra sjukdomar som nattblindhet, benskörhet och cancer. Även en överdos kan vara mycket allvarlig, och därför finns det bestämmelser om vilka livsmedel som ska vitaminberikas samt med hur mycket av varje vitamin. Dessutom utförSample clean-up methodologies based on supercritical fluid extraction (SFE) have been developed for determination of fat-soluble vitamins in foods. This thesis focuses on method development, stressing important issues concerning sample pre-treatment, extraction conditions and collection parameters. It was demonstrated that by using SFE followed by saponification and determination using RP-HPLC wit
Cancer är den näst vanligaste dödsorsaken i världen idag och en tredjedel av Sveriges befolkning blir diagnosticerade med cancer under sin livstid. Av alla cancerfall i Sverige, så är prostatacancer den vanligaste och bröstcancer den näst vanligaste, medan hos enbart kvinnor så är bröstcancer den vanligaste med 29,2 % av cancerfallen. Överlevnaden efter en cancerdiagnos har i Sverige ökat sedan 70Cells are commonly used in research to evaluate toxicity and efficiency of drugs. However, to further increase the usefulness of cells as well as the understandings of effects of different interventions, new methods must constantly be developed and refined. Today, many assays use end-point analysis of large populations of cells, to evaluate the research question. However, there are many cases when
BACKGROUND: Critically ill newborn infants undergo a variety of painful procedures or experience a variety of painful conditions during their early life in the neonatal unit. In the critically ill paediatric and neonatal population, clonidine is prescribed as an adjunct to opioids or benzodiazepines aiming to reduce the doses of these drugs that are required for analgesia or sedation, or to facili
