A REE-bearing fluorosilicate from the Tommot REE-Nb deposit in Yakutia, Russia, described without a name in 1966, is characterized here as a new species, proshchenkoite-(Y), of the vicanite group of borosilicates. Wavelength-dispersive electron probe analyses gave the following empirical formula: (Y3.70REE7.54Ca1.55Na1.16Mn0.77Th0.10Pb0.01)(Sigma 14.83)(Fe0.832+M0.15Ti0.02)(Sigma 1.00)Ca-1.00 (P0.
In situ CO2 and CO measurements from five Integrated Carbon Observation System (ICOS) atmosphere stations have been analysed together with footprint model runs from the regional Stochastic Time-Inverted Lagrangian Transport (STILT) model to develop a dedicated strategy for flask sampling with an automated sampler. Flask sampling in ICOS has three different purposes, namely (1) to provide an indepe
Convection-enhanced delivery (CED) is a technique to bypass the blood-brain barrier and deliver therapeutic agents into the brain. However, animal studies and preliminary clinical trials have reported reduced efficacy to transport drugs in specific regions, attributed mainly to backflow, in which an annular zone is formed outside the catheter and the fluid preferentially flows toward the surface o
Det får anses vara allmänt vedertaget att barn är en särskilt utsatt grupp världen över. Vid en bedömning av barns utsatthet är faktorer såsom flyktingskap och sjukdom av relevans. Sjuka flyktingbarn är således alldeles särskilt sårbara. Förståelsen för detta bör genomsyra all lagstiftning som rör barn, där barnets bästa ska sättas i främsta rummet. Denna uppsats har haft till syfte att undersök
On the 24th of February 2022 Russia decided to invade its neighbour Ukraine. On this day Putin delivered a speech in which he described his thoughts and why he deemed it necessary to invade Ukraine. This speech he sought to legitimise the action taken by his regime. This was not the first time since the start of this millennium that Russia invaded a neighbour which in turn raised the question if t
Outdoor climate has considerable impact on the indoor climate and it is therefore important to adapt the buildings to the climate. This thesis shows how to improve indoor climate in a climate which it is hot, dry in the summer and cold in the winter. My investigative unit is a middle class house in the town Baalbek in Lebanon and the purpose of the study is to come up with proposals on possible so
Leaving a sustainable society for our children is considered an arbitrary goal for the environmental work that is currently taking place in Sweden. Today, 140 million tonnes of non-hazardous waste is generated in Sweden, which is unsustainable. 31% of the non-hazardous waste is traced to the construction industry, the mining industry excluded. Today, the waste is an unused resource that is purchas
Hummeln is a simple impact structure located in south-eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln-1 with a focus on impact metamorphism and the impact process. We find that the drilling has penetrated a complex sedimentary successio
En av de mest anmärkningsvärda förändringarna i Europas familjerätts-system är framväxten av rättsverkningar kopplat till samboskap. Denna utveckling har även under det senaste årtiondet följts av en snabb förändring av samhällsattityderna gentemot samkönade par vilket har lett till ökat rättsligt erkännande i många av EU:s medlemsländer. Ett område av EU-rätten som potentiellt skulle kunna påverkOne of the most remarkable changes in European family law systems is the development of new institutions that provide a legal status for unmarried couples. Over the last decade, this change has also been accompanied by a rapid evolution of social attitudes towards same-sex couples that has lead to legal recognition in many Member States of the EU. An area of EU law where such developments could ha
In an economic environment signified by shortened product lifecycles, product proliferation and reduced profit margins, product replacement decision making (PRDM) ought to be an important part of management. The case is however often that considerably more energy and resources at a firm are spent at the opposite task, hence product development. The main purpose of this master thesis was to constru
Due to the recent financial turmoil we have noticed how exposed our financial situations are. Not only the financial market has been affected but also major socio-economic crises have risen as a result of the recession. Despite this, there is a willingness to take part in trading on the financial market.

Biogeochemical cycling of silicon (Si) in the Barents Sea is under considerable pressure from physical and chemical changes, including dramatic warming and sea ice retreat, together with a decline in dissolved silicic acid (DSi) concentrations of Atlantic inflow waters since 1990. Associated changes in the community composition of phytoplankton blooms will alter the material comprising the deposit
The decarbonization of the energy-intensive and natural-resourced-based industries is associated with potentially large economic costs. In this paper, I explore how decarbonization may affect the profitability and market value of these industries. I also discuss the possibility of compensating for the investment costs through higher prices and enhanced productivity. I answer these questions using
BackgroundAnimal bedding remains an underutilized source of raw material for bioethanol production, despite the economic and environmental benefits of its use. Further research concerning the optimization of the production process is needed, as previously tested pretreatment methods have not increased the conversion efficiency to the levels necessary for commercialization of the process.ResultsWe
Greater central artery stiffness is observed in people with type 2 diabetes (T2DM). Elevated blood pressure (BP) and altered arterial wall structure/composition in T2DM are generally considered as main drivers for this alteration. However, because conventional arterial stiffness measures are BP-dependent and as such an influence of BP remains in a measure, it is unclear if greater central artery s
Arctic clouds are sensitive to atmospheric particles since these are sometimes in such low concentrations that clouds cannot always form under supersaturated water vapor conditions. This is especially true in the late summer, when aerosol concentrations are generally very low in the high Arctic. The environment changes rapidly around freeze-up as the open waters close and snow starts accumulating
Despite the large scientific interest on robot learning forobject picking tasks, the research on object placingis too limited. Commonly, placing is simplistically consideredas a trivial task, but real life manipulation problems indicatethe exact opposite. A placing task can have different levels ofcomplexity, ranging from the simplest tabletop placing of anobject, to more complex cases such as loa
Mineral evolution is concerned with the timing of mineral occurrences, such as the earliest reported occurrences in the geologic record. Minerals containing essential Li have not been reported from rocks older than ca. 3000 Ma, thus the lithian tourmaline (fluor-elbaite) and mica (lepidolite) assemblage from a pegmatite near Zishineni associated with the ca. 3000 Ma Sinceni Pluton presents unusual
OBJECTIVE: To elicit psychological and psychosocial problems existing in patients in dialysis and their partners, its being felt that the diversity involved has important implications for how service in dialysis units is delivered to patients and their partners. METHODS: The results of a series of interviews of 39 patients in dialysis and 21 partners of theirs, each interview individual, concernin
