Hollow fiber supported liquid membrane sampling and speciation of lead(II) from aqueous solution using a selective carrier (Kelex 100) is studied. An optimization of different variables affecting permeation performance (chemical conditions of the sampling module - pH, concentration and nature of the acceptor phase, extractant concentration; membrane impregnation form; sampling time; and hollow fib

Context. In 2005, fusions between the androgen-regulated transmembrane protease serine 2 gene, TMPRSS2, and E twenty-six (ETS) transcription factors were discovered in prostate cancer. Objective: To review advances in our understanding of ETS gene fusions, focusing on challenges affecting translation to clinical application. Evidence acquisition: The PubMed database was searched for reports on ETS

Background: Sex pheromones are essential in moth mate communication. Information on pheromone biosynthetic genes and enzymes is needed to comprehend the mechanisms that contribute to specificity of pheromone signals. Most heliothine moths use sex pheromones with (Z)–11–hexadecenal as the major component in combination with minor fatty aldehydes and alcohols. In this study we focus on four closely

The formation of lumps during large scale wetting of spray dried powders is a common problem in the industry. The result is a large energy demand if an efficient mixing is to be achieved at the industrial scale. If more knowledge regarding the phenomena governing lump formation is obtained, the unit operation could be optimized and made more efficient. As a part of increasing the understanding of

Background: Functional and morphological changes of the heart influence blood flow patterns. Therefore, flow patterns may carry diagnostic and prognostic information. Three-dimensional, time-resolved, three-directional phase contrast cardiovascular magnetic resonance (4D PC-CMR) can image flow patterns with unique detail, and using new flow visualization methods may lead to new insights. The aim o

Since their discovery more than 70 years ago antibiotic drugs have been efficient tools for treating bacterial infections, and their use has reduced the number of fatalities and the suffering from bacterial diseases. However, the use of antibiotics may lead to resistance to the same or other antibiotics. The risk of resistance appears to be larger in veterinary medicine, since antibiotics have bee

Chromosomal instability is a known hallmark of many cancers. DNA polymerases represent a group of enzymes that are involved in the mechanism of chromosomal instability as they have a central function in DNA metabolism. We hypothesized that genetic variation in the polymerase genes may affect gene expression or protein configuration and by that cancer risk and clinical outcome. We selected four gen

The Swedish electricity market was divided into four bidding areas on 2011.11.01. The division gave implications to the trade of electricity in the spot market as well as the financial market. Four bidding areas create smaller markets and coupled with an unbalance of production and consumption in the areas, the liquidity on contracts for area price risk management has decreased drastically. This e

We’re living in a time where more and more evidence of our impact on the environment appears every day. A lot of resource and time have been spent in order to identify and inform about the ecological footprint us humans enlarge day by day. The realization of human impact on the environment introduced large scale research and UN reports on the subject and a definition and goal to strive after was e

While migrating to other countries, persons with disabilities often face additional obstacles as non-nationals and having a disability. Being a vulnerable group it might be hard for them to access remedies and justice. As a light in the darkness, the Convention on the Rights of Persons with Disabilities was adopted in 2006 in order to promote and protect the human rights of persons with disabiliti

Tidigare studier har dokumenterat ett flertal fossila meteoriter samt höga koncentrationer av utomjordisk kromit (ett järn-kromoxidmineral) i cirka 467 miljoner år gamla, mellanordoviciska sedimentlager. Fynden antas vara resultaten av ett tillfälligt förhöjt inflöde av meteoritiskt material, efter uppbrytningen av en kropp i asteroidbältet – de så kallade L-kondriternas föräldrakropp – för omkriNumerous fossil meteorites and high concentrations of sediment-dispersed extraterrestrial chromite (EC) grains with typical ordinary chondritic composition have previously been documented from 467±1.6 Ma Ma lower Kundan (Middle Ordovician) strata. These finds most likely reflect a temporarily enhanced influx of ordinary chon- dritic matter, following the disruption of the L chondrite parent body i

Human trafficking is the world’s third largest organized crime after the illegal trade in arms and drugs. It is a growing problem in our increasingly globalized world and people are daily transported between countries to be exploited for different purposes. Not even Sweden is spared from this cynical business, although we may not hear much about it. The aim of this study was to investigate how Swe

With a worldwide increase in climate-related disasters and the global temperature on the rise, the effects of climate change are already being felt. Among those most at risk are the poor in developing countries, often living in informal settlements or „slums‟. In order to reduce associated risks and strengthen people‟s own coping capacities, there is an urgent need for knowledge about the factors

Freshwater of good quality is important, even necessary, for human society as well as natural ecosystems to function. However, the uneven distribution of freshwater globally together with other problems such as over-population and pollution all contribute to water stress and water scarcity in many countries. These issues are getting worse and worse. A growing number of companies and organizations

This thesis examines and analyses the relationship between the principle of complementarity and the principle of universal jurisdiction. The establishment of the International Criminal Court provides for the first time in history a permanent international criminal institution. One of the most important principles on which the ICC is built upon is the principle of complementarity. The road towards

The international character that surrounds the shipping industry has traditionally meant that rules regarding the public law of the sea or the private maritime law are internationally regulated through regulations, state practice, international conventions or international customary law. Since the 1970s, there has been an increasing concern for both the marine environment and the safety onboard sh

PURPOSE: To explore modifications of the 2021 European Resuscitation Council/European Society of Intensive Care Medicine (ERC/ESICM) guideline algorithm for neuroprognostication after cardiac arrest to improve its prognostic accuracy.METHODS: Post-hoc analysis of four prospective multicentre studies (TTM, TTM2, KORHN and ProNeCA). We raised the Glasgow Coma Scale motor (GCS-M) inclusion threshold

Background: Aortic valve calcification (AVC) is an underlying pathophysiological mechanism in aortic stenosis, which shares many risk factors with diabetes. However, the association between dysglycemia and early stages of AVC remains unclear. The aim was to examine the associations between stages of dysglycemia and signs of AVC among middle-aged individuals from the general population. Methods: Th

Background: Severe alpha-1-antitrypsin deficiency (AATD) is a known risk factor for early development of emphysema and COPD. By the Swedish national screening program within the years 1972–74 a cohort of individuals with severe AATD (PiZZ) was identified and regularly followed up. The aim of this study was to investigate alveolar volume (VA) and the ratio VA/Total lung capacity (VA/TLC) for the de

Compared to lake area and water level, lake storage capacity more intuitively reflects regional climate changes. In this study, we first derived lakebed elevation profiles for individual ICESat-2 tracks based on the underwater stratification of laser photons, then integrating all valid elevation tracks within the water body to interpolate the bathymetry. On this basis, we calculated the capacity a
