Discordant U–Pb data of zircon are commonly attributed to Pb loss from domains with variable degree of radiation damage that resulted from α-decay of U and Th, which often complicates the correct age interpretation of the sample. Here we present U–Pb zircon data from 23 samples of ca. 1.7–1.9 Ga granitoid rocks in and around the Siljan impact structure in central Sweden. Our results show that zirc

This study focus on the gelation process of 1-methylidene ethane-1,2-dicarboxylic acid (MIA) polyesters and what causes the gelation. The influence of oxygen during the syntheses, how the molecular weight is affected and how the polyester changes chemically was studied. Analytical methods used were SEC, titration and NMR. The replicability of the experiments was investigated and confirmed. Testing

Social networking sites (SNS) play an important role in human’s daily life today. Individuals, employ different SNS where they mainly self-disclose and share personal information with other users. SNS have been characterized as a new communication landscape, with SNS users to be benefited in more ways when using them, such as with information and enjoyment. However, this online information sharing

Working with innovation has become an essential factor in driving firm success in fast-changing industries like the energy sector. As a result, a considerable amount of previous research has focused on the innovation activities of employees working in R&D or similarly. However, a more recent field of research has focused on studying the employees outside these innovation-specific functions and

Lactobacillus reuteri is known as probiotics with health benefits. Freeze-drying is frequently used to preserve probiotics and keep them alive. However, freeze-drying through freezing and drying might cause some damages to the probiotic’s cells. Formulation by protective agents including cryoprotectants and lyoprotectants prior to freeze-drying can prevent and reduce these damages. In this study,

The study of the impact of social capital on economic outcomes is currently on the rise. Social capital is a multidimensional concept hard to grasp. This paper makes an attempt to comprise such range of dimensions and analyzes its impact in a potential channel for growth, financial development. Three rural-based provinces of Vietnam are the places where this analysis takes upon. Vietnamese society

In this master´s dissertation I investigated if it is possible to increase the total stability for excavations in clay, if suction is taken into account during the calculations. The work has been performed at, and in cooperation with, Sweco Civil AB as well as the Dept. of Construction Sciences at Faculty of Engineering LTH, Lund University. The objective of this master´s dissertation is to asse

Pantomime is a means of bodily visual communication that is based on iconic gestures that are not fully conventional. It has become a key element in many models of language evolution and a strong candidate for the original human-specific communicative system (Zlatev et al. 2020). Although pantomime affords successful communication in many contexts, it has some semiotic limitations. In this study,

For two-dimensional steady pure-gravity water waves with a unidirectional flow of constant favorable vorticity, we prove an explicit bound on the amplitude of the wave, which decays to zero as the vorticity tends to infinity. Notably, our result holds true for arbitrary water waves, that is, we do not have to restrict ourselves to periodic or solitary or symmetric waves.

We investigate the space–time picture of string evolution and hadron production in a fully string-based model for high energy collisions involving heavy-ions. We find that although the density of strings is quite large at the time of hadronization in a central heavy-ion collision, the initial overlap between them right after the collisions is not necessarily large. We also find that when including

During the first year of NASA's Mars 2020 mission, Perseverance rover has investigated the dark crater floor unit of Jezero crater and four samples of this unit have been collected. The focus of this paper is to assess the potential of these samples to calibrate the crater-based Martian chronology. We first review the previous estimation of crater-based model age of this unit. Then, we investigate

Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. It is thus of high importance to understand the characteristics of each

Despite the importance of SMEs for innovation activity, questions remain concerning the determinants of their innovative performance and the role of different types of collaboration and partners. The present paper empirically analyzes the role played by different types of R&D collaborations in the persistence of SME innovative performance. We used a longitudinal database to identify all the Sw

Kan en silkeshandske vara en symbol för makt? I denna tänkvärda volym samlas en grupp namnkunniga historiker för att ge perspektiv på överlappande frågor kring genus, materialitet och politik. Genom historiska fallstudier som sträcker sig från 1500-talet och fram i modern tid utforskar författarna brännpunkter i företeelser som diplomati, kvinnors inflytande och tillskrivandet av betydelse hos förCan a silk glove be an expression of power? In this carefully curated volume, internation­ally renowned historians have come together to explore the interconnected perspectives of gender, materiality, and politics. As the authors elaborate on these topics, the volume offers contributions covering a period from the sixteenth century to the present day, investigating political culture and diplomacy,

Business angels are a vital source of capital for innovative start-up firms. However, many potentially attractive investment opportunities are rejected during the angel's decision-making process. Information asymmetry, risk and distrust in the relationship between the investor and the entrepreneur result in investment barriers. The concept of proximity has been proposed as a conceptual foundation

The growth of Sweden’s urban population necessitates new approaches for increasing the sustainability and energy efficiency of multifamily buildings. The development of such approaches will require a holistic and integrated understanding of the factors driving the decision making of both professionals who design buildings and end-users who live in them. This paper, therefore, uses the goal framing

This paper discusses the syntax–prosody mapping at the clause-level, or the potential absence thereof. In particular, the paper reexamines the validity and the necessity of the clause-level mapping constraint, MatchClause, proposed in Match Theory (Selkirk 2009, 2011). First, it will be shown, based on the results of previous empirical studies, that data from embedded clauses in Japanese do not pr
