Genom osteohistologiska analyser kan stora mängder information erhållas. Förutom möjligheten att uppskatta åldern och mognadsgraden hos ett djur kan tillväxtsmärken i skelettet, så kallade ’growth marks’ eller GM, också innehålla information om benens tillväxtshastighet, djurets tillväxtstrategi och till och med levnadssätt. Denna studie avhandlar histologin hos fossiliserade ben tillhörande en haOsteo-histology provides information on age, growth strategies, and lifestyles of both recent and ancient animals. This study deals with the histology of fossilized bone from three groups of tetrapods – sea turtles, ichthyosaurs and plesiosaurs – all secondarily adapted to marine life, but with rather different bone microstructures. As a result of extensive vascularization (i.e. osteoporosis), ich

Building materials account for a high percentage of the non-land cost of self-help housing. Few studies, however, have examined the use of building materials by self-help builders and the practicalities of producing and distributing the materials in an alternative manner. This paper discusses the nature of construction by self-help in the intermediate-sized Colombian city of Pereira, focusing in p

Current strategies to reduce the climate impact of production and consumption are insufficient to meet the pressing targets of the Paris Agreement. To expand visions of the possible ‘solution space’ in climate transitions, we explore a framework based on two dichotomies centred around the role of labour and the composition of economic output. From these dichotomies we sketch out four pathways for

This article is based on anthropological fieldwork undertaken at two elite universities in Beijing. It addresses the paradoxical situation of the many instances of suicide among Chinese elite university students in Beijing, which constitute a public secret. The pressure of education weighs heavily on the shoulders of China’s only child in each family, known as the generation of little emperors and

ABSTRACT Background Posterior fossa tumours (PFT), among the most common childhood brain tumours, place children at risk of speech, language, and communication difficulties, often described in relation to cerebellar mutism syndrome (CMS) but also seen in children without mutism. Narrative ability refers to the capacity to understand, create, and share stories. Narratives can be analysed at the macBackgroundPosterior fossa tumours (PFT), among the most common childhood brain tumours, place children at risk of speech, language, and communication difficulties, often described in relation to cerebellar mutism syndrome (CMS) but also seen in children without mutism. Narrative ability refers to the capacity to understand, create, and share stories. Narratives can be analysed at the macrostructur

For the Inner Tracking System 3 (ITS3) upgrade, the ALICE experiment at CERN requires monolithic active pixel sensors of dimensions up to 97 mm×266 mm, occupying a large fraction of a 300 mm wafer. To manufacture such a wafer-scale device, larger than the single design reticle size, stitching is employed. The MOnolithic Stitched Sensor (MOSS) is a prototype silicon pixel sensor of 14 mm×259 mm siz

Water management is a critical factor for the performance and reliability of polymer electrolyte fuel cells (PEFCs) operating as energy generation systems. Inadequate operating conditions may lead to non-uniform water distribution, resulting in membrane dehydration or flooding of porous media, both of which adversely affect cell operation. In this work, a two-dimensional reduced-order model is dev

Musculoskeletal health is essential to health, well-being, and independence across the life course. Musculoskeletal conditions including inflammatory joint diseases, osteoarthritis, back pain, osteoporosis, and fragility fractures are among the greatest causes of disability globally imposing a major burden on health and social care and economic impact also through lost productivity. Despite effect

BACKGROUND: The aim was to improve the realism of patient models for Monte-Carlo based evaluation of image-based quantification of tumour volume and activity in [68Ga]Ga-DOTA-TOC PET and [177Lu]Lu-DOTA-TATE SPECT images.METHODS: Three phantoms from the XCAT population were used as basis. Tumour structures were obtained from segmentation of patient 68Ga-PET images and positioned at relevant positio

Lignins are a polymeric, renewable resource with remarkable structural diversity. Research is being conducted into the valorisation of lignins into value-added products. The absence of experimental libraries, in particular for process-modified oligomers, hampers analytical feedback to these valorisation efforts. Stochastic methods for generating libraries in-silico have been proposed, but were not

Lime-cement mixing is a method used for ground improvement of clay soils. Before mixing at a field site, laboratory samples are prepared and tested to decide the amount of lime-cement binder needed to reach the desired material strength. Strength measurements are not possible before a sample hardens, and the test process to predict final strength takes 30 days. Resistivity measurements are possibl

The notion of human rights is built on the fact that they are universal rights and thus applies to everyone without exceptions. Despite this irregular workers are denied their labour rights and their human rights due to the fact that they are living in a country unlawfully. The states use methods as regularizing irregular migrants or enabling tougher sanctions against irregular migration in order

Over the past decades, sustainable production and consumption pattern has been addressed on a global level. Business is a powerful stakeholder in the development of sustainable consumption and production systems as it represents a great proportion of competence, resources and mechanisms (Charter, Gray, Clark and Woolman, 2008). The global approach toward achieving sustainable production and consum

The purpose of this Master’s Thesis is to create a model of a converting line factory. The model will be used to investigate factory performance when altering the order structure as well as other what-if scenarios. The model should also be easily adaptable so that it can be used to model other factories as well without the need to rebuild it from scratch. The main results of this study show that

Purpose: The purpose of this paper is to examine how sponsorship crises can affect brands. Especially brands that have decided to part from their athletes are taken into account in this paper. Besides that, it aims to establish managerial guidelines that help to communicate the termination of sponsorship activities. Methodology: To understand the underlying theory, secondary data is gathered throu

Acknowledging, the research gap within sustainability transitions in analysing the local scale of transition processes, this work primarily, seeks to contribute to sustainability transitions studies by identifying the main factors that are enabling and hindering the materialization of low carbon mobility in Cuenca, Ecuador. The use of a case study as a research strategy and the nature of the rese

The behaviour and fate of stem cells is governed by the material properties of their surrounding microenvironment. Hence emulating the extracellular matrix poses as an attractive target for tissue engineering endeavours to create a stem cell substrate. Currently, the knowledge of the material properties is mostly limited to the macroscopic level which considerably limits the understanding of tissu
