The up-converting ZrO2:Yb3+,E3+ nanomaterials were prepared with the combustion and sal-gel methods. The structure of the materials was cubic except for the minor monoclinic and tetragonal impurities associated with the use of the sal-gel method. The XANES results revealed only the trivalent form for both the Yb and Er dopants. The distance distributions calculated from EXAFS confirm that Er3+ and

Popular Abstract in Swedish Många cancerceller har ovanligt höga nivåer av proteinet DEK och i vissa fall av leukemi har man hittat en genetisk förändring som leder till en variant kallad DEK-NUP214. Man tror därför att DEK kan vara en av faktorerna som bidrar till att vanliga celler omvandlas till cancerceller. En sådan roll har visats i experimentella modeller där man även sett att cancerceller The DEK gene is upregulated in a growing number of cancers and translocated to form the DEK-NUP214 fusion gene in a subset of acute myeloid leukemia. In this thesis, we studied the cellular and molecular functions of the DEK and DEK-NUP214 proteins. We found that the expression of DEK is increased by the leukemia-associated fusion protein NUP98-HOXA9, suggesting that DEK may be a downstream mediat

The effect of hydrogen loading on the stability and mobility of vacancy-H complexes in aluminum is determined by applying DFT and the minimum-mode-following method. The binding energy per H-atom within a complex is found to range from -0.36 eV/atom to -0.34 eV/atom for an occupancy of, respectively, a single and eight H-atoms. When eight H-atoms are neighboring the vacancy the total binding energy

The aim of this short article is to question the archaeological classification of the Neolithic archaeological cultures, and to raise questions about how to understand the fragmentary material culture in terms of social agency and cultural expression. e settlement of Jonstorp in southern Sweden as a case of the south Scandinavian Pitted Ware complex presents theoretical and methodological implicat

Changes to the carbon cycle in tropical forests could affect global climate, but predicting such changes has been previously limited by lack of field-based data. Here we show seasonal cycles of the complete carbon cycle for 14, 1ha intensive carbon cycling plots which we separate into three regions: humid lowland, highlands, and dry lowlands. Our data highlight three trends: (1) there is differing

Major businesses today involves complex supply chains with world-wide sourcing and marketing which create new risks for both the individual enterprise and the society at large. Supply chain disruptions are seen as the primary threat to a company's revenue driver. To be able to cope with undesired events, companies need to review their business continuity management (BCM). To increase the know

Intense agricultural activity in recent years has resulted in a greater use of pesticides in order to improve productivity. However, these pesticides may contain some pollutant component in their composition. Once present in the environment and/or in excess, they can cause damage to the local flora and fauna. The aim of this study was to evaluate the interference of pesticides in the reproductive

The purpose of this report is to evaluate the fire safety of Tekniska nämndhuset in Huddinge. The focus of the report is on the safety of people during evacuation in case of fire. Property and environmental damage has not been taken into consideration. Tekniska nämndhuset is an office building accommodating several administrations within Huddinge municipality, there is no co-operation regarding fi

The aim of this study is to increase the knowledge in practice of value co‐creation by providing information on how co-creation is manifested in C-­‐G lookbook. This thesis employs a qualitative strategy with an inductive approach, and data were collected through virtual observation. Theoretical framework is divided into three different parts, in which various theories within s

Abstract Authors: Maria Silversand och Maria Svensson Title: Praktiken ger liv åt teorin - skoltrötta ungdomar Supervisor: Johan Cronehed The purpose of this assignment has been to investigate how the definition of “school fed” has been construed in newspaper articles and if, and how, it has changed over time. From our question formulations which were; how the concept ”school fed” is defined, mea

In the world today 2.5 billion have no access to improved sanitation. This causes social, economic and environmental consequences and therefore weakens all three pillars of sustainability. The sanitation deficit although decreasing in relative terms has increased in absolute numbers since 1990. Conventional water-based systems are costly, pollute the environment and require heavy resource use. Thi

This thesis aimed to work with different techniques of building archaeology, both traditional and digital. The goal was to define the possibilities offered by the “traditional” and the “digital” building archaeology but also to show the limits of these two methods. The main issue of discussing methodological problems in building archaeology was the need to define digital building archaeology, espe

This paper examines five contemporary spiritual festivals, courses and gatherings for women in a Western post-secular context. The purpose of the paper is to contribute to the current feminist debate on alternative spirituality, often referred to as new age, in regard to gender essentialism and agency. Firstly, the analysis explores how the examined discourses construct women as subjects. Secondly

It is common that oxygen is a limited factor in microbial decomposition of a substance. Biostimulation with oxygen release compound, increase dissolved oxygen in groundwater and stimulate natural decomposition of petroleum hydrocarbon. Many places today are contaminated and using biostimulation with oxygen release compound will probably increase in the future. Today, the knowledge about what happe
