A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test

Type 2 diabetes mellitus (T2DM) and HER2 are associated with cancer although the role of HER2 in T2DM is not well defined. Our aim was to investigate the association between HER2 levels and T2DM and whether that association was different in Swedish people born in Iraq or Sweden.

Foreign Direct Investment (FDI) is often considered to be favorable to long-run economic growth and has in recent years been promoted as a poverty-reducing tool. Although FDI to developing countries has increased rapidly in recent decades, Sub-Saharan Africa (SSA) has been unsuccessful in attracting large inflows of FDI. This study assesses the effect FDI has had on poverty and human development i

Despite the importance of infrastructure, a big funding gap can be seen in infrastructure procurement. Public-Private Partnerships (PPPs) were once seen as a solution, but years later the results are underwhelming. As the industry can be susceptible to corruption, concerns have emerged about PPPs. To confront these concerns, this study aims to investigate if there is a link between corruption and

Shared ground loops (SGLs) combine shared ground heat exchangers with distributed heat pumps across multiple properties and may offer a route to decarbonise heating where individual heat pumps or heat networks are not feasible. SGLs can be installed in homes and buildings with limited outside space for a heat pump or insufficient demand density to support a heat network. To make the most of potent

The duality characteristics of budgeting between the flexibility driven decision making and the integration focused management control inspire the author to investigate how the flexibility and integration domains influence business controllers? choices of IS technologies used in budgeting. This includes the enterprise resource planning (ERP) system, business intelligent (BI), web tool and spreadsh

The article outlines the most pressing justice questions in a transition to a fossil fuel-free welfare state in Sweden.

Nitrogen and sulfur are key elements in the biogeochemical cycles of marine ecosystems to which benthic foraminifera contribute significantly. Yet, cell-specific assimilation of ammonium, nitrate and sulfate by these protists is poorly characterized and understood across their wide range of species-specific trophic strategies. For example, detailed knowledge about ammonium and sulfate assimilation

Electric power systems are undergoing huge changes due to the shift from conventional power production to more renewable-based generation like solar and wind. This is primarily driven by the need to mitigate climate change by reducing CO2 emissions. The shift to more generation from solar and wind will affect the dynamical behaviour of power systems, and consequently how they should be controlled.

Geothermal energy is classified as a renewable energy source and it utilizes the heat generated in the earth primarily from the natural radioactive decay of isotopes of uranium, thorium and potassium. Heat is extracted from the earth to generate geothermal energy via a carrier, usually water occurring either in the liquid or steam phase. In the late 19th century and the early 20th century, the fir
