Biomethane in the transport sector-An appraisal of the forgotten option

The last 20 years efforts to find a long-term and large-scale biofuel alternative to petrol and diesel for the transport sector have been intensified with a focus on liquid biofuels, such as ethanol, methanol and Fischer-Tropsh diesel derived from wood. The large-scale production of biomethane has so far largely been overlooked in comparative studies that focus on the long-term renewable options.

Complexation between DNA and surfactants and lipids: phase behavior and molecular organization

The interaction between DNA and various cationic species, e. g. cationic surfactant (CS), has a broad biological and biotechnological significance. In the cell nucleus as well as in transfection formulations, other species, mainly zwitterionic lipids, are also present but their exact role needs elucidation. A closer investigation of the stability of structures formed as well as the molecular arran

Online Journalism and Civic Cosmopolitanism: Professional vs. participatory ideals

Web-based civic participation in democracies, especially in the sprawling domain of alternative politics, continues to grow. In this paper I explore the intersection of two trajectories of such participation: one that takes the form of journalism (broadly understood) and the other that is transnational in character. Participatory journalism unavoidably evokes normative issues that professional jou

Regulation of Human Papillomavirus Type 16 Late L1 mRNA Splicing

Popular Abstract in English Each year an estimated 530 000 new cases of cervical cancer are diagnosed and more than 275 000 women die from cervical cancer worldwide (2). Cervical cancer is caused by sexually-acquired infections with a subset of human papillomavirus (HPV) (359, 360). HPV is the most common viral infection of the anogenital tract (2). Almost all sexually active individuals will be iHuman papillomaviruses (HPVs) cause almost half of the human cancers that are attributable to viruses. HPV type 16 is the most carcinogenic type among the HPVs and is detected in 50% of all cervical cancers. HPV-16 infects epithelial cells and HPV-16 gene expression is tightly linked to the differentiation stage of the infected cells. Early HPV-16 genes are expressed in basal layers of the epithel

Anisotropic density growth of bone-A computational micro-sphere approach

Bones are able to adapt their local density when exposed to mechanical loading. Such growth processes result in densification of the bone in regions of high loading levels and in resorption of the material in regions of low loading levels. This evolution and optimisation process generates heterogeneous distributions of bone density accompanied by pronounced anisotropic mechanical properties. While

Gene genealogies reveal differentiation at sex pheromone olfactory receptor loci in pheromone strains of the European corn borer, Ostrinia nubilalis

Males of the E and Z strains of the European corn borer Ostrinia nubilalis (Lepidoptera: Crambidae) are attracted to different blends of the same pheromone components. The difference in male behavioral response is controlled by the sex-linked locus Resp. The two types of males have identical neuroanatomy but their physiological specificity is reversed, suggesting that variation at the periphery re

Human adipose cells in vitro are either refractory or responsive to insulin, reflecting host metabolic state.

While intercellular communication processes are frequently characterized by switch-like transitions, the endocrine system, including the adipose tissue response to insulin, has been characterized by graded responses. Yet here individual cells from adipose tissue biopsies are best described by a switch-like transition between the basal and insulin-stimulated states for the trafficking of the glucos

Effects of Dopamine Signaling on Recovery and Inflammation after Ischemic Stroke

Ischemic stroke, resulting from occlusion of a brain artery is the most common type of stroke with a prevalence of 15 million people and the leading cause of long-term disability worldwide. Importantly, partial spontaneous recovery of lost neurological functions occurs mainly during the first months after stroke onset, albeit to a limited extent. Recovery has been attributed to mechanisms of compe

Heat and mass transport in a nonlinear fixed-bed catalytic reactor: Hot spots and thermal runaway

Transient heat and mass transport in a wall-cooled tubular catalytic bed reactor is numerically investigated. A two-dimensional pseudo-heterogeneous model, accounting for transport in the solid and fluid phases, with axial and radial dispersions is used to describe transport in the reactor. The effects of inlet process conditions, viz., temperature and concentration, are investigated and their imp

Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC

A search for the Standard Model Higgs boson in proton-proton collisions with the ATLAS detector at the LHC is presented. The datasets used correspond to integrated luminosities of approximately 4.8 fb(-1) collected at, root s = 7 TeV in 2011 and 5.8 fb(-1) at root s = 8 TeV in 2012. Individual searches in the channels H -> ZZ(()*()) -> 4l, H -> gamma gamma and H -> WW (()*()) -> ev mu v in the 8 T

Spin-state studies with XES and RIXS: From static to ultrafast

We report on extending hard X-ray emission spectroscopy (XES) along with resonant inelastic X-ray scattering (RIXS) to study ultrafast phenomena in a pump-probe scheme at MHz repetition rates. The investigated systems include low-spin (LS) Fe-II complex compounds, where optical pulses induce a spin-state transition to their (sub)nanosecond-lived high-spin (HS) state. Time-resolved XES clearly refl

Between Daring and Deliberating : 3G as a sustainability issue in Swedish spatial planning

The thesis shows how different aspects of sustainable development have been handled or not handled in the third generation infrastructure development in Sweden. The difference between the design of the 3G development - emphasizing competition, growth and regional access, based on a strong technological optimism - and the implementation, as the roll out struck the landscape, including the non-handl

Genome-wide association studies in East Asians identify new loci for waist-hip ratio and waist circumference.

Sixty genetic loci associated with abdominal obesity, measured by waist circumference (WC) and waist-hip ratio (WHR), have been previously identified, primarily from studies conducted in European-ancestry populations. We conducted a meta-analysis of associations of abdominal obesity with approximately 2.5 million single nucleotide polymorphisms (SNPs) among 53,052 (for WC) and 48,312 (for WHR) ind

Plasma 25-hydroxyvitamin D concentration and lymphoma risk: results of the European Prospective Investigation into Cancer and Nutrition

Background: The relation between vitamin D status and lymphoma risk is inconclusive. Objective: We examined the association between prediagnostic plasma 25-hydroxyvitamin D [25(OH)D] and lymphoid cancer risk. Design: We conducted a study nested within the European Prospective Investigation into Cancer and Nutrition cohort of 1127 lymphoma cases and 1127 matched controls with a mean follow-up time

Too difficult to govern? An assessment of the governability of transport biofuels in the EU

Transport biofuels are currently the subject of heated debate in the EU. In the past decade the deployment of these technologies has been justified by claims of attractive environmental, geopolitical and rural development benefits. However, expectations have rapidly turned into deep criticism regarding the sustainability of these technologies and the desirability of pursuing the biofuel path. This

Nag Hammadi-sabbaten och den platslösa kategorin: Religiös förändring och självbildens transformation under senantiken

Many scholars and philosophers inspired by Antiquity, have commented upon a transformation of lived religion and a changing picture and technology of the Self during Late Antiquity. The Nag Hammadi Library contains a diverse body of thought and it is here argued that these texts are found in the epicentre of Late Antique conversion of religion and Self, containing important illustrations of new em

Decentralised paediatric HIV care in Ethiopia: a comparison between outcomes of patients managed in health centres and in a hospital clinic.

Background : In order to increase access to antiretroviral therapy (ART) in HIV-infected children, paediatric HIV care has been introduced in health centres in Ethiopia, where patients are managed by health professionals with limited training. Objective : To compare outcomes of paediatric HIV care in hospital and health centre clinics and to determine risk factors for death and loss to follow-up (
