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

Until recently, the general level of detail in full car crash models has not allowed a physical modeling of rubber bushings with solid elements. This is partly because of the difficulty in modeling the complex characteristic of rubber, but also due to limited understanding of the mechanical properties of rubber materials. The main focus of this Master’s thesis project is to develop a new and im

This research examines how consideration of place attachment and community values can inform the development and implementation of fair and equitable climate change adaptation (CCA) practices in the Australian local government context. The research adopts a qualitative approach, using semi-structured interviews with expert interviewees and reflective thematic analysis to answer three research ques

In the context of China’s concerning decline in fertility rates and the widespread normalization of the ‘996’ overtime culture, the connection between overtime work and fertility assumes considerable importance. This research is firmly grounded in the theoretical framework of the Theory of Planned Behavior (Ajzen, 1991), which investigates the complex relationship between overtime work and fertili

Our study aims to address the research gap pertaining to the identification of leadership characteristics that managers consider essential in a multigenerational team within contemporary organizations. Additionally, the study examines the impact of stereotypical thinking on leadership effectiveness. Regarding the key findings, managers emphasized the evolving expectations of leadership, highlighti

Studying dissolution of oral drug substances is crucial throughout the drug development process. Current methods are time consuming and require large quantities of both the drug and dissolution media. Thus, exploring new methods is highly desirable. UV imaging, an analytical technique based on real-time absorbance measurements, can be used in early drug discovery to study drug dissolution and has

Transylvania’s countryside, characterized by a mostly agrarian society with a rich multicultural heritage is being threatened by Romania’s tendencies of chaotic modernization and rapid urbanization. This research aims to find a viable solution for sustaining the cultural, natural, and social environment in rural Transylvania, by analysing the potential of tourism development. Integrated Rural Tour

Den digitala omställningen har ökat genom åren och har fungerat till en fördel för företag och organisationer generellt. Hastigheten på transformationstillväxten har bibehållits i nutid, vilket har resulterat i att mjukvarusystem utvecklas kontinuerligt. Som en naturlig effekt av detta fenomen, bör aktuella företag alltid ligga i framkant för att förbli konkurrenskraftiga. Studier har visat att pr

Cancer is a widespread and commonly fatal disease in constant need of new treatments. Traditionally, new pharmaceuticals have been tested in 2D models. This is not ideal, as 2D environments do not reflect the in vivo milieu of the cells. Instead, it has been increasingly suggested to implement 3D models, which are thought to be more predictive of in vivo responses to treatment. It has been shown t

Background: environmental impact from health care contribute to a substantial part of the public sector’s consumption based emission of greenhouse gases in Sweden. An issue, recognized by the health care sector itself, is the increasing use of single-use products. Objective: to compare environmental impact and cost differences between a single-use, ResposableTM, and mixed setup of the surgical in

Abstract Purpose: The purpose of this thesis is to investigate how different types of fans experience personalization in sports marketing and to analyze how each Fan type can be motivated by understanding how their fan experience could be optimized further. Methodology: This study was a qualitative study. The study was carried out using an abductive approach where literature was combined with empi

Freevalve AB develops camless valvetrains for internal combustion engines using pneumatic and hydraulic systems. An air compressor is used to generate pressure in the pneumatic system. To further increase efficiency of the Freevalve system, a new compressor tailored to its purpose, is being developed in house. This thesis is part of the development of this compressor, which is a reciprocating pis

A growing environmental issue today is the amount plastic pollution in the ocean. To investigate how it might affect marine life, an important aspect is to study how plastics are transported by ocean currents and where it ends up. This can be done by use of Lagrangian simulation of plastic particles in computer ocean models. To improve the quality of the output from such simulations the number of

This Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-D

In occupational therapy and occupational science, it is important to clarify the perspective from which the analysis of occupation is addressed. The purpose of this paper is to present a tentative structure for describing occupation, allowing for analysis in a lifelong panorama as well as for the immediate experience a person acquires from performing a single occupation. The concept of occupationa

This study presents 20 patients, randomised to receive either a collagen-treated or an ordinary Dacron graft for aortic reconstructions, and the results of a skin-prick test, blood parameters and ELISA for anti-collagen antibodies as well as NMR pictures during a 6 week follow-up period. Forty per cent (4/11) of those receiving a collagen impregnated graft had a significantly increased titre of an

The secosteroid hormone active vitamin D [1,25(OH)(2)D-3] is a key player in the regulation of calcium homeostasis and bone mineralization. In addition, it has antiproliferative and prodifferentiating effects on various cells in vitro and in vivo. The action of 1,25(OH)(2)D-3 is mediated through the vitamin D receptor (VDR), which belongs to the superfamily of steroid/thyroid hormone nuclear recep
