Non-traditional stable isotope systems are increasingly used to study micronutrient cycling and acquisition in terrestrial ecosystems. We previously proposed for zinc (Zn) a conceptual model linking observed isotope signatures and fractionations to biogeochemical processes occurring in the rice soil environment and we suggested that 2’deoxymugineic acid (DMA) could play an important role for rice

Vocal problems are common among workers in voice demanding occupations. For sustaining vocal health, it is important to find efficient ways to reduce strain on the voice at work. One way to do so is optimizing the room acoustics for communication. However, we do not know enough about what kind of room acoustic conditions that support voice and speech most efficiently, and if talkers of different a

Objectives To examine whether multimorbidity aggregates in families in Sweden.Design National explorative family study.Setting Swedish Multigeneration Register linked to the National Patient Register, 1997-2015. Multimorbidity was assessed with a modified counting method of 45 chronic non-communicable diseases according to ICD-10 (international classification of diseases, 10th revision) diagnoses.

Background: Various factors modulate circulating testosterone in men, affecting interpretation of testosterone measurements. Purpose: To clarify factors associated with variations in sex hormone concentrations. Data Sources: Systematic literature searches (to July 2019). Study Selection: Prospective cohort studies of community-dwelling men with total testosterone measured using mass spectrometry.

At the emergency department (ED), it is important to quickly and accurately determine which patients are likely to have a major adverse cardiac event (MACE). Machine learning (ML) models can be used to aid physicians in detecting MACE, and improving the performance of such models is an active area of research. In this study, we sought to determine if ML models can be improved by including a prior

Background: Hypertension is the leading risk factor for cerebral small vessel disease. We aimed to determine whether antihypertensive drug classes differentially affect microvascular function in people with small vessel disease. Methods: We did a multicentre, open-label, randomised crossover trial with blinded endpoint assessment at five specialist centres in Europe. We included participants aged

Bioelectronics holds great potential as therapeutics, but introducing conductive structures within the body poses great challenges. While implanted rigid and substrate-bound electrodes often result in inflammation and scarring in vivo, they outperform the in situ-formed, more biocompatible electrodes by providing superior control over electrode geometry. For example, one of the most researched met

Due to the large extent of seawater surface over the globe, aerosol particles spend significant time being transported over this type of surface. Therefore, global aerosol circulation is largely impacted by the processes particles undergo during long-range transport overseas. In this study, we investigated submicron aerosol (PM1) chemical composition changes during long-range transport events over

This thesis encompasses an introductory part and five papers related to developing techniques and phantoms required for the further growth of photoacoustic imaging (PAI). In PAI, images are created by detecting acoustic waves followed by the absorption of laser light, enabling high spatial resolution while maintaining high optical contrast. Due to the distinct absorption patterns of various chromo

Vi ville se om kunderna har olika förväntningar på service beroende på vilken butik de handlar i och hur detta påverkar säjarnas och föetagets agerande. Studien visade att företagen har profilerat sig på två helt skilda sätt. Detta har gjort att kunderna förväntar sig olika nivå av service vilket också företagen förstått och därmed leverarar de den service kunderna efterfrågar.

Den offentliga sektorn i Sverige har under de senaste decennierna påverkats av stora reformvågor. De bakomliggande idéströmningarna har kommit att gå under samlingsnamnet New Public Management där ekonomiska värden starkt betonas. Man menar att det inte bör göras någon skillnad mellan privata företag och offentliga organisationer i valet av organisationsstruktur och förspråkar att den offentliga s

The exhaustion doctrine (also known in some jurisdictions as the ''first sale doctrine See U.S. Copyright Code Section 109(a)'') is one of the basic rules of intellectual property (IP) system, and is applied to many IP rights, from copyright to trademark. The term ''exhaustion'' or ''first sale'' describes the concept of this rule, where, after the &

Over a 15-year period, mobile phones have evolved from providing one single feature - the mobile voice call - to multi-featured multi-media communication and entertainment devices. Customer value has been added through successive integration of features previously conveyed by dedicated devices, as clock, timer, camera, media player, radio, etc. This continued integration strategy now poses several

Problem: Personalen är en betydelsefull komponent i detaljhandelsföretag, i många fall till och med viktigare än de produkter som erbjuds. Vi anser att detta är något som alla företag bör ta i beaktning och som i framtiden kommer att ha en än mer betydande roll och som kommer att kunna kopplas till ett företags framgång. För att personalen ska känna sig betydelsefulla har vi förstått att motivatio

Vid en diskussion om nivån på den svenska bolagsskatten är det av stor vikt att avgöra huruvida diskussionen rör den nominella eller den effektiva skattesatsen. Den nominella skattesatsen uppgår till 28 procent och återfinns i 65 kap. 14 § IL. Den effektiva skattesatsen är däremot inte given utan kan i viss utsträckning påverkas, eftersom den bestäms genom att dividera skatt på årets resultat med

There are two matters, which have important impacts on development of the international intellectual property rights (IPRs). The first is the significant economic importance of the IPRs and its large share in international trade and the second is the protection of IPRs especially in developing and importing countries. More than two thirds of the WTO members are developing countries (DCs) and they

Syftet med denna studie är att förklara tänkta positiva effekter och eventuella fallgropar, vid införande av ett Shared Service Center, med konsideration av de organisationsförändringar som sker till följd av implementeringen av centret, samt analysera hur prissättningen integrerar den nya enheten i organisationen. För att svara på den inledande frågeställningen har en abduktiv ansats använts. Läm

The purpose of my study is to question the model service marketing triangle and propose an alternative ways of looking at service marketing. The study is based on a deep, qualitative research. In the research of the material an abductive approach has been used. The primary information sources are interviews with project workers, which are being analyzed together with the theoretical background in

The purpose of this study is to provide a longitudinal examination, within grocery retailing, of four marketing tools and their impact on enhancing customer loyalty. The study examines whether the relationship between the four marketing tools and customer satisfaction has a positive effect on attitude and behavior loyalty. The findings from this study show that the marketing tools have not helped
