Popular Abstract in Swedish Radiojodbehandling av sköldkörteln är den vanligaste radiofarmakaterapin. För att beräkna aktiviteten 131I som krävs för att ge en viss stråldos till sköldkörteln behöver sköldkörtelns massa och den individuella biokinetiken bestämmas. Biokinetiken består vanligtvis av det individuella upptaget av jodid och den biologiska halveringstiden av jod i sköldkörteln. Den bioloRadioiodine therapy of hyperthyroidism is the most frequently performed radiopharmaceutical therapy. To calculate the activity of 131-I to be administered for giving a certain absorbed dose to the thyroid, the mass of the thyroid and the individual biokinetic data, normally in the form of uptake and biologic half-time, have to be determined. The biologic half-time is estimated from several uptake

Optical spectroscopy has been used as a supplement to conventional techniques for analyzing and diagnosing cancer in many human organs. Because ocular tumors may be characterized by their different melanin content, we investigated the feasibility of using transscleral visible/near-infrared spectroscopy (Vis/NIRS) to estimate the quantity of melanin in a novel uveal melanoma phantom of ex vivo porc

Human activity is constantly causing environmental problems due to production and release of numerous chemicals. A group of compounds of special concern is persistent organic pollutants (POP). These toxic, lipophilic chemicals have a high chemical and biological stability, and tend to accumulate in the lipid phase of living organisms. A major sink for POPs are sediments, and consequently these are

Background Carrying the cyclin-dependent kinase inhibitor 2A (CDKN2A) germline mutations is associated with a high risk for melanoma. Penetrance of CDKN2A mutations is modified by pigmentation characteristics, nevus phenotypes, and some variants of the melanocortin-1 receptor gene (MC1R), which is known to have a role in the pigmentation process. However, investigation of the associations of both

Research at the division of Packaging Logistics, Lund University, has been performed in numerous areas, ranging from organisational learning and sustainability to process integration and service development. One of these is the new and complex research area of traceability. When it comes to food scandals, from the mad cow disease at the end of the 90s to the more recent incident where glass has b

Variations in molybdenum isotopic composition, spanning the range of similar to 2.3 parts per thousand in the terms of Mo-97/Mo-95 ratio, have been measured in sediment cores from three lakes in northern Sweden and north-western Russia. These variations have been produced by both isotopically variable input of Mo into the lakes due to Mo isotopic heterogeneity of bedrock in the drainage basins and

Background: The first tissues to be deprived of perfusion and oxygenation in a hypovolemic situation and the last ones to be reperfused are the subcutaneous tissue and the gastrointestinal mucosa. We hypothesized that measurements of subcutaneous tissue gases and pH might reflect simultaneous changes in oxygenation of the intestinal mucosa. The aim of this study was to evaluate tissue gases and pH

A rheological study of mixed micelles formed by PEO-PPO-PEO triblock copolymer P123 and nonionic surfactant C12EO6 in aqueous solutions has been carried out with the purpose of investigating the time dependence of a shape transition of the mixed micelles and characterizing the shape before and after the transition. The rheology results presented in this report give clear evidence that the P123-C12

Background Lagoons are shallow coastal water bodies which occupy 13 % of the world’s total coastlines. Healthy lagoons have a rich aquatic fauna and can provide an economic benefit for the people living in its vicinity. Due to anthropogenic activities, the water quality in many lagoons is deteriorating. The Mundaú-Manguaba Estuarine-Lagoon System is no exception. BOD-rich water from the nearby sug

I en tid präglad av globalisering, teknisk innovation och individualism har kampen om talangfulla medarbetare vuxit fram. Arbetsgivarens behov av att framstå och uppfattas som attraktiv har kommit att bli betydande, speciellt i relation till Generation Y som olikt tidigare generationer byter arbetsgivare flera gånger under sin yrkeskarriär. En generationskohort, så som Generation Y, består av indiIn an era characterized by globalization, technological innovation and individualism the battle for top talent has emerged. Employers’ need to be seen and perceived as attractive have become significant, especially in relation to Generation Y that unlike previous generations change employer several times during their professional careers. A generational cohort, as Generation Y, consists of individ

Den 1 juli 2018 fick Sverige en ny våldtäktslagstiftning. Den nya lagstiftningen innebar att rekvisitet som skiljer olagligt och lagligt sexuellt umgänge förändrades. I tidigare våldtäktslagstiftning har tvång varit en förutsättning för att en våldtäkt skulle anses förövad. Med den nya regleringen står nu frivillighet i centrum för denna bedömning. Lagändringen föregicks av mycket debatt. Det diskOn the 1st of July 2018 Sweden changed the law on sexual assault. The new law meant that the prerequisite that separate sexual assault and legal sexual intercourse was changed. In previous legislation coercion was needed for a perpetrator to be convicted of sexual assault. The new law instead places voluntariness at the center of the court’s assessment. The amendment was preceded by much debate. T

Akustisk infångning kan bli ett värdefullt verktyg i medicinsk forskning Från ett enda blod- eller urinprov kan läkare få massvis med information om en patient - information som ger ledtrådar om allt från det allmänna hälsotillståndet till eventuell förekomst av infektioner eller inflammationer, eller huruvida patienten lider av en viss sjukdom. Detta beror på att provet innehåller massor av så kaMicrofluidic systems allow for fast and precise manipulation of small volume samples in a highly controlled environment. In such a system, acoustic trapping is a powerful tool, enabling non-contact isolation of cells and microvesicles from complex media. In this technique, an ultrasonic standing wave is introduced in the microchannel. The standing wave exerts size-dependent acoustic forces on part

Popular science summary: An MK-801 Hyperactivity Model in Zebrafish Larvae Schizophrenia is a mental disorder characterized by psychosis, depression and cognitive impairments. The severity of this disease is easily underestimated, since the manifestations are not consequently lethal. Additionally, Schizophrenia is correlated with a 50 times increased risk of attempted suicide. Considering that a

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

Issue of study: The starting point for innovation is ideas, which can be seen as fuel to the innovation process as it supplies the innovation funnel with new or improved concepts that finally may spark innovation. There is a vast literature on the success of a few radical ideation methods and the use of creativity tools, while few have dealt with the use and effects of ideation approaches in pract

Public space are open spaces and areas where people in the city move around, get together and play, regardless of background, age, ethnicity, gender and income. This is particularly important in poor neighborhoods where people have no access to places where to socialize. Well designed and planned public spaces are symbols of several important aspects of a city; health, safety, culture and local ec

An upcoming trend in the current IT-landscape is to outsource services to so called Cloud Service Providers (CSPs). However, many companies are still sceptical to this new kind of services, since they bring about a certain loss of control. For this reason, it is important for CSPs to show that their services are secure. There are several options in proving this and it is up to every CSP to choose

Bytesrätten har utvecklats i samklang med den svenska bostadspolitiken. Under tidigt 1900-tal fanns det en stark liberal inställning till relationen mellan hyresgäster och hyresvärdar. I 1907 års nyttjanderättslag (1907:36), NyttjL, gällde grundläggande avtalsrättsliga principer. Hyresgäster fick enbart säga upp kontrakt om hyresvärden nekade dem överlåtelse av kontraktet utan skälig anledning. I The right to barter a rented apartment has developed in harmony with the Swedish housing policy. During the early twentieth century a strong liberal doctrine dominated the relationship between tenants and landlords. The usufruct law (nyttjanderättslagen) from 1907, was based on contractual principles. Contracts could be for as long as 25 years in the towns and tenants were only allowed to terminat
