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
Thirty-five years after the massive earthquake that shook the city on July 28, 1976, Tangshan residents still live with the scars of the losses and injuries that were suffered. This case study is about possible recent changes to commemorations and public memory in Tangshan. Firstly, it will examine how the Tangshan earthquake is commemorated publicly through monuments, ruins and at schools. Second
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
Corruption is at present costing the European society enormously amounts, in forms of money and in relation to social, economic, political and legal development. Democracy is viewed as one of the fundamental pillars of the European Union, which additionally has been one of the Union’s highest priorities since its foundation. One aspect that may be hindering the increasing of democracy is a state’s
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
As authorities, the universities are subject to the principle of access to official documents. Records generated during the research process are thus to be regarded as official documents, even though there are disputes over exactly when they are to be considered as such. Scientists are, to various degrees, dependent of access to earlier research data, which may have been collected during research
The open innovation process is complex and requires adoption throughout to be successful and much has been accounted for in the initial stages, the front-end. However, research calls for a better understanding of the back-end, meaning the downstream activities of the organisation. The part of the process connecting the front-end to the back-end is understood as the transition phase and is consider
Supply chain management (SCM) has become more challenging than ever, considering the effect of globalization on organizations as operating through transnational business networks. Conventional supply chains have been facing struggles such as lack of advanced technologies and traceability in operation, which then leads to operational inefficiencies. Blockchain (BC) technology offers a set of featur
The vehicle industry is making great strides in electric and hybrid technologies, representing a significant step towards reducing emissions from personal vehicles. In order to make the transition to new hybrid technologies as convincing as possible, well-functioning and smooth transitions between traditional combustion engines and electric motors are required. So-called mild hybrids enable a cos
Thesis purpose The purpose of our thesis is to explore how and why consumers with low prior knowledge educate themselves about sports supplements and what effect gender has. Methodology Our research derives from a pragmatic orientation. We conducted a multi-method qualitative study, combining observations and interviews in order to explore and understand the online customer journeys of consumers
Purpose - The purpose of this thesis is to explore the relationship between sustainable consumption and gender identity, with a particular emphasis on femininity, and to establish the normative idea of the green consumer. Methodology - As part of this thesis, three focus groups were conducted with a total of 19 participants. During the first part of the focus groups, the research aim was disguise
The world continues to be shaped by crises in both new and familiar forms. International and non-international armed conflicts and disasters are barriers to individual wellbeing, development, stability, and in the case of the former, represent a basic challenge to peace. The aftermath of such crises, in which communities can be rebuilt and the fabric of society can be mended, can be a time for rec
Poly-3-D-hydroxybutyrate (PHB) is a biopolymer naturally produced by a range of bacterial species. PHB production both from glucose and xylose has also been enabled by engineering the robust baker’s yeast Saccharomyces cerevisiae, however yields remain low. In the present study, additional modifications were carried out in S. cerevisiae strains already expressing functional enzymatic pathways for
G protein-coupled receptor 30 (GPR30) is a ubiquitously expressed receptor reported to bind and become activated by estrogen (17β-estradiol). However, the role of GPR30 as an estrogen receptor for rapid estrogenic signaling is not completely accepted, and controversies exist regarding the identity of the cognate ligand, signaling, and subcellular localization of the receptor. Expression of GPR30 i
