Liksom en trädstam uppvisar årsringar som kan användas för att beräkna dess ålder, bildas också tillväxtringar i tänderna hos många djur, även hos dem som regelbundet byter tanduppsättning. Detta fenomen noterades av paleontologen Richard Owen redan i mitten av 1800-talet, men det är först de senaste decennierna som forskningen inom tandersättningscykler hos utdöda djur har tagit fart. Så kalladeThe dentine of teeth from five genera of mosasaurs [i.e., Clidastes, Halisaurus, Dollosaurus (Prognathodon),cf. Platecarpus, and Tylosaurus] and a Mesozoic crocodylian (Aigialosuchus) from the Campanian of the Kristianstad Basin, southernmost Sweden, displays two types of incremental growth lines; i.e., von Ebner’s and, for the first time in extinct animals, Andresen’s lines. These lines are homol

Offentligrättsliga sanktioner av EU:s konkurrensrätt är ett välutvecklat område. Detsamma gäller dock inte för civilrättsliga sanktioner. Kommissionen har antagit en Grönbok, som beskriver flera problem som behöver lösas för att uppnå att privata sanktioner i framtiden fungerar som ett naturligt komplement till de offentligrättsliga. Skadeståndsanspråk framförs i nationell domstol i en medlemsstat

Purpose: This master thesis aims to understand how the development of the leading FM companies will influence upon the service strategy in Crawford Sweden. Design/approach: Literature review of published work concerning FM along with interviews with a range of people within Crawford and in the FM business. Research limitations: Owing to constraint of time, the authors have had to make some delimit

Phenological vegetation characteristics are valuable inputs to several ecosystem-related models: including carbon exchange and climate change. Phenological characteristics are effective measures of changes in vegetation in an area and are subject to the seasonal and inter-annual climatic variations. In arid and semi-arid ecosystems, precipitation is the main driving factor for changes in vegetatio

Long time series of satellite remotely sensed Normalized Difference Vegetation Index (NDVI) as an indicator of vegetation greenness can be used in a broad range of research topics such as climate change, vegetation dynamics and desertification monitoring. The first phase of this study tests a practical method using Hyperion imagery onboard on Earth Observing-1 (EO1) spacecraft for simulation of MO

Smart cyber-physical systems (S-CPSs) are complex engineered systems empowered by cyber-physical computing and equipped with the capability of reasoning, learning, adapting, and evolving. As an outcome of data-driven dynamic computing, reasoning capabilities, and the run-time obtained own knowledge, nonlinear and emergent behavior of S-CPSs whilst in operation is an open issue, not experienced in

Introduction: Post-traumatic stress disorder (PTSD) and substance use disorder frequently co-occur and tend to have their onset during adolescence. Although research has highlighted the importance of treating these disorders in an integrated fashion, there is a dearth of empirically validated integrated treatment options for adolescents with this comorbidity. This paper describes the study protoco

Objective: The authors aimed to clarify the sources of parent-child transmission for suicide attempt and death by suicide. Methods: Three sources of parent-child resemblance (genes plus rearing, genes only, and rearing only) were examined in parents and offspring from four family types from Swedish national samples: intact nuclear families, families with a not-lived-with biological father, familie

PURPOSE: To explore the frequency and outcomes of cataract surgery in eyes with previous vitrectomy. SETTING: Fifteen European countries. DESIGN: Retrospective cross-sectional register-based study. METHODS: The European Registry of Quality Outcomes of Cataract and Refractive Surgery (EUREQUO) contains data on baseline characteristics, surgery, and follow-up for cataract surgeries. Previous vitrect

Context. NGC 2264 is a young cluster whose accretion properties can be investigated in detail by taking advantage of the FLAMES data in the context of the Gaia-ESO Survey. In fact, the analysis of the Hα emission line profile can provide us with information about the accretion and ejection activity of young stars. However, a strong nebular emission that contributes to the Hα emission can alter the

The pharmaceutical and healthcare sector is a prime target for cybercriminals around the world. These cyber-attacks represent significant challenges in the context of data protection and data security. The General Data Protection Regulation (GDPR) imposes strict rules regarding the processing and analysis of personal data. In conventional approaches, data analysts request data from various sources

The comparative study of planetary systems is a unique source of new scientific insight: following the six “key science questions” of the “Planetary Exploration, Horizon 2061” long-term foresight exercise, it can reveal to us the diversity of their objects (Question 1) and of their architectures (Question 2), help us better understand their origins (Question 3) and how they work (Question 4), find

As climate models can be used to reproduce historical climates, the outcomes can be used to put climate extremes in to a proper historical perspective. This also allows investigation of nonlinear properties of hydrologic processes (e.g. precipitation, runoff) to better understand regional hydrologic dynamics. To this end, the present study uses results from a so-called 'paleosimulation' (i.e. simu

Background: Newborns, admitted to the Neonatal Intensive Care Unit (NICU), are exposed to a large number of medications, the majority of which are not labeled for use in infants, especially in preterm newborns, because clinical trials on their benefits and harms are lacking. There is a huge gap in knowledge on pharmacokinetic (PK) data in sick preterm infants, including that of drug penetration to

The modelling of biological systems often consists into differential equation models that need to be fitted to experimental data. During this complex process, the practical experience of the biologist and the theoretical abstraction of the modeller require back-and-forth refinements of the model, design of new experiments and inclusion of more data-points into the fitting procedure. Available opti

Background: The quest for diagnostic tools for the detection of cutaneous malignant melanoma (cMM) is ongoing. A challenge in cMM care is not overlooking cMM at an early stage, while simultaneously avoiding unnecessary biopsies or excisions of benign pigmented skin lesions (PSLs). A novel hyperspectral imaging (HSI) device is shown to have potential for differentiating equivocal PSLs in Asian skin
