1. 1. Networks in epigenetics

   Författare :Kuljeet Sandhu; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Networks are ubiquitous. It is only recently, we started exploring what purpose they serve in real world. Biological research supposedly has, and will be, benefited most from the network science because of inherent complexity embedded in its multilayered organization. LÄS MER

3. 2. Methane dynamics in northern lakes : Insights from multi-scale observations

   Författare :Jonathan Schenk; David Bastviken; Magnus Gålfalk; Damien Maher; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Methane; Lakes; Variability; Sampling design; Models;

   Sammanfattning : Methane (CH4) is a potent greenhouse gas which is emitted to the atmosphere from both natural and anthropogenic sources. Current evidence indicates that lakes account for a large part of the global emissions of CH4, but their contribution is difficult to quantify because of large temporal and spatial variability in processes leading to CH4 fluxes from lakes to the atmosphere.

4. 3. School journeys : ideas and practices of new education in Portugal (1890-1960)

   Författare :Inês Félix; Anna Larsson; Björn Norlin; Daniel Tröhler; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; school journeys; educational modernity; ‘Reason’ of schooling; historia med utbildningsvetenskaplig inriktning; history of education;

   Sammanfattning : In this dissertation I examine school journeys in secondary education in Portugal between 1890 and 1960, focusing on State regulation, educational ideas and school practice. By bringing together the various parts of a broader discourse on a way of thinking and making schooling, I look at how this active method was regulated, argued and reportedly undertaken with a twofold aim: to expand the knowledge on the history of school journeys, and to contribute to the research on the ideas and practices of educational modernity.

5. 4. Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data

   Författare :Abdulhakim Abdi; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Net primary production; Africa; Drylands; Coupled human and natural systems; Human-Environment Relations; Food security; Earth observation; Remote Sensing;

   Sammanfattning : The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. LÄS MER

7. 5. Care and handling of a peripheral intravenous line

   Författare :Anna Lundgren; Linköpings universitet; []
   Nyckelord :Peripheral cannula; time in situ; thrombophlebitis; intravenous infusions; nursing care; documentation; MEDICINE; MEDICIN;

   Sammanfattning : The general aim was to study the way nurses plan, take care of and document a peripheral intravenous cannulae (PIV) related to complications, and to give a basis for quality assurance (QA). The methods used were document analysis, interview, observation and intervention regarding cannula time in situ. LÄS MER
