Characterization of stratum corneum molecular dynamics by natural-abundance (13)c solid-state NMR.

Despite the enormous potential for pharmaceutical applications, there is still a lack of understanding of the molecular details that can contribute to increased permeability of the stratum corneum (SC). To investigate the influence of hydration and heating on the SC, we record the natural-abundance (13)C signal of SC using polarization transfer solid-state NMR methods. Resonance lines from all maj

Dimension splitting for time dependent operators

In this paper we are concerned with the convergence analysis of splitting methods for nonautonomous abstract evolution equations. We introduce a framework that allows us to analyze the popular Lie, Peaceman-Rachford and Strang splittings for time dependent operators. Our framework is in particular suited for analyzing dimension splittings. The influence of boundary conditions is discussed.

Model-Based Comparison of Batch and Continuous Preparative Chromatography in the Separation of Rare Earth Elements

The demand for rare earth elements (REEs) is growing, while the future supply is uncertain. Their unique electronic characteristics make them irreplaceable, and the commercial value of pure fractions is high. A model-based simulation study is presented that compares batch chromatography with the twin-column MCSGP (multicolumn countercurrent solvent gradient purification) process for ion-exchange c

Teamarbete på operationssal, organisationsdesign och patientsäkerhet

Teamarbete är vanligt inom hälso- och sjukvården. I mitt avhandlingsarbete har jag studerat teamarbete på operationssal med fokus på hur det praktiska arbetet faktiskt går till. Avhandlingens delstudier berör sådant som den praktiska användningen av formella rutiner (WHOs checklista för säker kirurgi), ledarskap på operationssal, olika professioners syn på det gemensamma arbetet, testning av en me

Phylogenetic generic classification of parmelioid lichens (Parmeliaceae,Ascomycota) based on molecular, morphological and chemical evidence.

Parmelioid lichens are a diverse and ubiquitous group of foliose lichens. Generic delimitation in parmelioid lichens has been in a state of flux since the late 1960s with the segregation of the large, heterogeneous genus Parmelia into numerous smaller genera. Recent molecular phylogenetic studies have demonstrated that some of these new genera were monophyletic, some were not, and others, previous

Direct Conversion of Human Fibroblasts to Induced Neurons

Popular Abstract in Swedish Celler som har förmågan att ge upphov till nästan alla typer av mogna celler i en organism kallas för pluripotenta stamceller. Förutom deras förmåga att bilda olika specialiserade celltyper har pluripotenta stamceller även den unika förmågan att genomgå ett obegränsat antal celldelningar. Under utvecklingen av en organism genomgår pluripotenta stamceller en process somDuring direct cellular reprogramming, forced expression of key transcription factors (TFs) directly converts one terminally differentiated cell type into that of another fate, exemplified in this theses by the conversion of fibroblasts into functional induced neurons (iNs). Direct conversion of mouse fibroblasts to functional neurons was established in 2010, and the starting point of my doctoral

Social Ecography : International trade, network analysis, and an Emmanuelian conceptualization of ecological unequal exchange

This thesis demonstrates how network analysis, ecological economics and the world-system perspective can be combined into an ecographic framework that can yield new insights into the underlying structure of the world-economy as well as its surrounding world-ecology. In particular, the thesis focuses on the structural theory of ecological unequal exchange, a theory suggesting a relationship between

Platinum Interference with siRNA Non-seed Regions Fine-Tunes Silencing Capacity.

Knowledge concerning the molecular mechanisms governing the influence of non-coding RNAs on protein production has emerged rapidly during the past decade. Today, two main research areas can be identified, one oriented toward the use of artificially introduced siRNAs for manipulation of gene expression, and the other one focused on the function of endogenous miRNAs. In both cases, the active molecu

Dual phylogenetic origins of Nigerian lions (Panthera leo)

Lion fecal DNA extracts from four individuals each from Yankari Game Reserve and Kainji-Lake National Park (central northeast and west Nigeria, respectively) were Sanger-sequenced for the mitochondrial cytochrome b gene. The sequences were aligned against 61 lion reference sequences from other parts of Africa and India. The sequence data were analyzed further for the construction of phylogenetic t

Thermal detection of surface plasmons on gold nanohole arrays

We used a thin-film thermocouple to detect the thermal effect of surface plasmons excited in Au nanohole array structures. We found that the thermal electromotive force of Au film with periodic nanohole structures is three times greater than that of a bare Au film for 785-nm laser excitation at a given power. This effect is caused by the resonant excitation of localized surface plasmons in the nan

A Gender-Just Peace: Exploring the Post-Dayton Peace Process

This article is rooted in the understanding that global ideas of liberal democratic peace and the gendered dynamics of peacebuilding need to be confronted. The aim is to explore the challenges of localizing liberal democratic peace by exploring efforts such as those undertaken by women’s organizations in Bosnia-Herzegovina to promote a gender-just peace. The Dayton Peace Accord was the new “social

Intensified Tuberculosis Case-Finding in HIV-Positive Adults Managed at Ethiopian Health Centers: Diagnostic Yield of Xpert MTB/RIF Compared with Smear Microscopy and Liquid Culture.

Detection of active tuberculosis (TB) before antiretroviral therapy (ART) initiation is important, but optimal diagnostic methods for use in resource-limited settings are lacking. We assessed the prevalence of TB, evaluated the diagnostic yield of Xpert MTB/RIF in comparison with smear microscopy and culture, and the impact of Xpert results on clinical management in HIV-positive adults eligible fo

Learning from incidents - A method for assessing the effectiveness of the learning cycle

Abstract in UndeterminedThis paper describes a method for assessing the effectiveness in the steps of the learning cycle: the 1st loop with reporting - analysis - decision - implementation - follow-up, and the 2nd loop on an aggregated basis. For each step, the dimensions considered the most relevant for the learning process (scope, quality, timing and information distribution) and for each dimens

Pollen productivity estimates and relevant source area of pollen for selected plant taxa in a pasture woodland landscape of the Jura Mountains (Switzerland)

Abstract in UndeterminedRelevant source area of pollen (RSAP) and pollen productivity for 11 key taxa characteristic of the pasture woodland landscape of the Jura Mountains, Switzerland, were estimated using pollen assemblages from moss polsters at 20 sites. To obtain robust pollen productivity estimates (PPEs), we used vegetation survey data at a fine spatial-resolution (1 x 1 m(2)) and randomize
