Cold-season methane (CH4) emissions may be poorly constrained in wetland models. We examined cold-season CH4 emissions simulated by 16 models participating in the Global Carbon Project model intercomparison and analyzed temporal and spatial patterns in simulation results using prescribed inundation data for 2000–2020. Estimated annual CH4 emissions from northern (>60°N) wetlands averaged 10.0 ± 5.
Objectives Studies on health effects of tobacco often rely on self-reported exposure data, which is subjective and can lead to misclassification. The aim of this study was to describe the prevalence of cigarette smoking, snus and e-cigarette use, as well as to validate self-reported tobacco use among young adults in Sweden. Method Participants of a population-based Swedish cohort (n=3052), aged 22
Galectins are a group of carbohydrate-binding proteins with a presumed immunomodulatory role and an elusive function on antigen-presenting cells. Here we analyzed the expression of galectin-1 and found upregulation of galectin-1 in the extracellular matrix across multiple tumors. Performing an in-depth and dynamic proteomic and phosphoproteomic analysis of human macrophages stimulated with galecti
The standard treatment of glioblastoma, an aggressive brain tumour, includes radiotherapy combined with temozolomide. Based on a randomised trial, showing five months increased survival, TTF has been introduced in the management of patients with good performance status. Data from the Swedish national quality registry for CNS tumours have been analysed for TTF usage. The results demonstrate that 65
Structural defects are detrimental to the efficiency and quality of optoelectronic semiconductor devices. In this work, we study InGaN platelets with a quantum well structure intended for nano-LEDs emitting red light and how their optical properties, measured with cathodoluminescence, relate to the corresponding atomic structure. Through a method of spectroscopy-thinning-imaging, we demonstra
Background:Earlier clinical detection of cancer may improve survival as well as offer opportunities for less invasive treatment options. This thesis explores whether the mitochondria and its related genes in the nuclear genome can be used as novel methods for the diagnosis and prognosis of cancers.Aims and Methods:Paper I: To investigate if mitochondrial dysfunction (characterized by mtDNA copy nu
It is well-known that an ideal extraction method enabling quantitative analysis should give complete extraction of the target analytes as well as minimal co-extraction of unwanted matrix substances. If the extraction method is part of a nontarget screening protocol, the desired analytes can differ widely in terms of chemical properties. In chromatography, terminologies such as recovery, selectivit
I denna rapport redovisar Kerstin Svensson och Monica Larsson (Socialhögskolan, Lunds universitet) ett projekt som tar upp civilsamhällets medverkan i myndigheters arbete då privatpersoner engageras som socialt stöd för medmänniskor. Syftet med projektet är att förstå tanken bakom medborgarmedverkan i myndigheters lagreglerade sociala insatser, hur den har utvecklats och vilka tendenser som finns
Building on Zoltán Dörnyei's authoritative work in the field of learner motivation, this book introduces a new conceptualization-Directed Motivational Currents (DMCs)-and sets out the defining aspects of what they are, what they are not, and how they are related to language learning motivation. Going beyond focused behavior in a single activity, DMCs concern intensive long-term motivation. The dis
In contexts of transnational migration, language skills provide the key to employability and successful integration into host country societies. To enhance the learning process, and facilitate transitions into the workforce, integrated programs of L2 learning have been developed in several Nordic countries. In these undertakings, language learning, vocational education, and workplace practice are
This article describes two inter-related research projects concerned with the teaching and learning of English in contemporary contexts, where English is changing its status from being the first language of specific groups of speakers to becoming a global lingua franca. Focussing respectively on learners of English as a second language (L2 users) in the Netherlands and Sweden, and on native speake
