Popular Abstract in English There is a natural tendency to take advantage of the most convenient energy source available. In this usage, convenient may mean most abundant, easiest to harvest or simplest to handle. Convenient will also correspond to cheapest in many instances. However, some consider it a responsibility to think of the long term costs of the energy we use. No form of energy is free The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. The burner was operated using methane and three s

IntroductionRecreational hunting in Sweden can be depicted as being embedded in two different but overlapping cultural and socio-economic contexts. One is the traditional non-commercial and stewardship-oriented form hunting, in Swedish called ‘allmoge’ hunting. It is characterised by a democratic hunting tradition where the local hunting team is ascribed a main role in wildlife management. These tThe paper is based on a study of hunting tourism enterprising in Sweden. The study examines how hunting tourism businesses in Sweden navigate in a complex social, economic and moral environment. The aim of the present paper is to identify how tensions between a market- oriented value sphere and a value sphere based on friendship- and community reciprocity are played out in hunting tourism entrepre

Determination of the atomic structure of solid surfaces typically depends on comparison of measured properties with simulations based on hypothesized structural models. For simple structures, the models may be guessed, but for more complex structures there is a need for reliable theory-based search algorithms. So far, such methods have been limited by the combinatorial complexity and computational

The upper Middle to basal Upper Ordovician succession (Darriwilian to Sandbian) of the Fågelsång-3 drill core provides new important information on the graptolite biostratigraphy of Scania, southern Sweden. The Scanian succession is known largely from drill cores and a few scattered outcrops exposing only parts of the interval. The Darriwilian Almelund Shale Formation overlies the Komstad Limeston

Typical massive multiple-input multiple-output (MIMO) architectures consider a centralized approach, in which all baseband data received by each antenna has to be sent to a central processing unit (CPU) to be processed. Due to the enormous amount of antennas expected in massive MIMO base stations (BSs), the number of connections to the CPU required in centralized massive MIMO is not scalable. In r

This article presents a critical assessment of 40 years of research that may be brought under the umbrella of energy efficiency, spanning different aggregations and domains-from individual producing and consuming agents to economy-wide effects to the role of innovation to the influence of policy. After 40 years of research, energy efficiency initiatives are generally perceived as highly effective.

Bilismen orsakar en mängd problem i våra städer. Det handlar dels om negativa effekter på människors hälsa på grund av skadliga partikelutsläpp, buller, trafikolyckor och stillasittande, dels om platsen den tar i anspråk vilket leder till trängsel och att värdefull mark tas i besittning av väginfrastruktur och parkeringsplatser. I ett större perspektiv bidrar biltrafiken även till utsläpp av växthTraffic accumulated by cars is responsible for considerable problems in our cities. The problem is partly about the negative effects on human health due to harmful particulate emissions, noise, traffic accidents and sedentary lifestyles, partly about the space it occupies, which leads to congestion, and the fact that valuable land is taken up by road infrastructure and parking lots. In a bigger pe

Historically, lethal exsanguinations and severe infections have been two major causes of maternal death. Gene mutations that lower the risk of profuse hemorrhage or severe infections would give a survival advantage. A single mutation of coagulation factor V, known as FV Leiden (FVL), can be such a beneficial mutation. FVL is common among Caucasians and today confers an increased risk of thromboemb

OBJECTIVES: To characterize the clinical phenotype and to study the course of disease in patients with Alström syndrome, with an emphasis on retinal function assessed with full-field electroretinography (ERG). METHODS: Three age- and sex-matched patients with Alström syndrome were selected from our retinitis pigmentosa register for repeated ophthalmologic examinations that included tests for color

Anaerobic digestion is a suitable method for the treatment of wastewater and organic wastes, yielding biogas as a useful by-product. A common way of preventing instability problems and avoiding acidification in anaerobic digesters is to keep the organic load to the digester far below its maximum capacity. An improved way of operating digesters would be to use monitoring and control systems for inc

Since its inception in 1980, the International Christian Embassy Jerusalem (ICEJ) has developed into a central player in the formation of Christian Zionism globally. It is known through its high profile in Israeli society, its financial, moral and political support for the State of Israel and its controversial mix of theology and politics. This article focuses on ICEJ's ideological and theological

The aquaporins (AQPs) form a family of integral membrane proteins that facilitate the movement of water across biological membrane by osmosis, as well as facilitating the diffusion of small polar solutes. AQPs have been recognised as drug targets for a variety of disorders associated with disrupted water or solute transport, including brain oedema following stroke or trauma, epilepsy, cancer cell
