The new CZT camera has a different technology compared to conventional scintillation gamma cameras. The CZT camera have pinholes instead of parallel hole collimators, a static gantry instead of a rotating one and detection material made of a semiconductor in- stead of a scintillation crystal. The images arising from the CZT camera have a difference in appearance compared to the images produced by
This thesis explores the under-recognised yet symptomatic visual motif of two women, a recurring theme within a vast array of pictorial examples. Its primary objective is to construct a theoretical and methodological framework capable of comprehending the multiplicity of images in the form of an image collection: The Atlas of Two Women. This inquiry primarily draws on Walter Benjamin’s concept of
The groundbreaking field of synthetic biology has immense potential to revolutionize our society by reducing our reliance on petroleum. With a growing demand for sustainable ingredients and molecules, companies like Amyris, who have successfully developed and commercialized this technology, are poised to reap significant rewards. I am privileged to work for a scientifically advanced organization t
By the end of the 1960s there was a growing environmental concern all around the globe. As a part of an answer to this challenge the need was recognized for a reorientation of the education processes towards developing knowledge, attitudes and skills for resolving the issues. This was the birth of the concept of Environmental Education (EE). However, this notion is far from being static as it went
Purpose of study: As both innovations and brand loyalty are becoming ever more important for companies today, it is of importance to understand how an organisation can handle the relationship between the explorative and exploitative units when working with these two constructs. The ultimate aim is to understand how service organisations can be managed in order to enhance brand loyalty through serv
This thesis is constructed on an examination of the global principles and operational methods of Socially Responsible Investment (SRI) and their linkage to Corporate Social Responsibility (CSR). These phenomena have implications for the sustainable banking business, which aims to deliver banking products and services aligned with a triple-bottom-line corporate approach contributing to sustainable
Finite element (FE) models based on quantitative computed tomography (CT) images are better predictors of bone strength than conventional areal bone mineral density measurements. However, FE models require manual segmentation of the femur, which is not clinically applicable. This study developed a method for automated FE analyses from clinical CT images. Clinical in-vivo CT images of 13 elderly fe
The aim of this paper is to provide guidance in selecting phosphorus recovery options within the municipal wastewater treatment sector regarding developing countries. This critical review includes a brief contextualization of the resource-oriented sanitation paradigm, the discussion of processes for phosphorus recovery based on methods at full-scale, pilot-scale and laboratory-scale, and a concise
The catches of bark beetles (Coleoptera: Scolytidae) were compared between attractive traps releasing semiochemicals and passive traps (cylindrical sticky screens hung, at 10 heights of 0.7-11.5 m, on poles). A central attractive-trap pole was surrounded by three passive-trap poles spaced 50 or 100 m away at the apices of an equilateral triangle. The catches of Tomicus piniperda and other scolytid
Geospatial information is indispensable for various real-world applications and is thus a prominent part of today’s data science landscape. Geospatial data is primarily maintained and disseminated through spatial data infrastructures (SDIs). However, current SDIs are facing challenges in terms of data integration and semantic heterogeneity because of their partially siloed data organization. In th
In contrast with human hemoglobin (Hb) in red blood cells, plant Hbs do not transport oxygen, instead research points towards nitrogen metabolism. Using comprehensive and integrated biophysical methods we characterized three sugar beet Hbs: BvHb1.1, BvHb1.2 and BvHb2. Their affinities for oxygen, CO, and hexacoordination were determined. Their role in nitrogen metabolism was studied by assessing t
Ship traffic is a major source of aerosol particles, particularly near shipping lanes and harbours. In order to estimate the contribution to exposure downwind of a shipping lane, it is important to be able to measure the ship emission contribution at various distances from the source. We report on measurements of atmospheric particles 7-20 km downwind of a shipping lane in the Baltic Se
Urbanisation as a megatrend shows no signs of weakening globally, or in the Nordic countries. At the same time, the overwhelming majority of environmental impacts are generated in cities. This derives from the economic growth generated by cities, as the decoupling of economic activity from environmental impacts has not been successful to date. Moreover, from a built environment perspective, urbani
Autoantibodies are an important marker of human autoimmune diseases and the development of simple, precise and reproducible immunoassays to detect autoantibodies is important to our understanding of human autoimmunity. GAD65 autoantibodies occur frequently in insulin-dependent diabetic patients and is a useful marker for IDDM. A RIA to detect immunoreactive GAD65 has not been described. In the pre
Background: The use of in vitro cell cultures is a powerful tool for obtaining key insights into the behaviour and response of cells to interventions in normal and disease situations. Unlike in vivo settings, in vitro experiments allow a fine-tuned control of a range of microenvironmental elements independently within an isolated setting. The recent expansion in the use of three-dimensional (3D) i
Introduction: Impaired long-term memory is a defining feature of mild cognitive impairment (MCI). We tested whether this impairment is item specific, limited to some memoranda, whereas some remain consistently memorable. Methods: We conducted item-based analyses of long-term visual recognition memory. Three hundred ninety-four participants (healthy controls, subjective cognitive decline [SCD], and
As the world population is pushing toward 8 billion, cardiovascular diseases (CVD) remain the leading cause of death worldwide, representing 30% of all global deaths. A large body of work has recognized that smooth muscle cells (SMCs) surrounding the blood vessels play a prominent role in the development and progression of cardiovascular diseases. SMCs are highly specialized cells with the main fu
Background Excess weight gain throughout adulthood can lead to adverse clinical outcomes and are influenced by complex factors that are difficult to measure in free-living individuals. Metabolite profiling offers an opportunity to systematically discover new predictors for weight gain that are relatively easy to measure compared to traditional approaches. Methods and results Using baseline metabol
BACKGROUND: Follow-up with computed tomographic angiography is recommended after endovascular aneurysm repair, exposing patients to significant levels of radiation and iodine contrast medium. Dual-energy computed tomography allows virtual noncontrast (VNC) images to be reconstructed from contrast-enhanced images using a software algorithm. If the VNC images are a good-enough approximation of true
