Anteckningar om Anders Stolts Stilleben

Essän om konstnären Anders Stolts skulpturala verk Stilleben sätter in arbetena i konsthistoriska, teoretiska, arkeologiska och haptiska perspektiv.This essay on the sculptural works of Anders Stolt puts the works in different contexts: art historical, theoretical, aeaeological, and haptic.

Abortive translation caused by peptidyl-tRNA drop-off at NGG codons in the early coding region of mRNA

In Escherichia coli the codons CGG, AGG, UGG or GGG (NGG codons) but not GGN or GNG (where N is non-G) are associated with low expression of a reporter gene, if located at positions +2 to +5. Induction of a lacZ reporter gene with any one of the NGG codons at position +2 to +5 does not influence growth of a normal strain, but growth of a strain with a defective peptidyl-tRNA hydrolase (Pth) enzyme

The Paradox of the 1970s: The Renaissance of International Banking and the Rise of Public Debt

The 1970s is a paradoxical decade. On the one hand, it marked the gradual demise of the industrial society and the end of the «Golden Age» of capitalism. On the other hand, the decade saw the renaissance of international banking and finance after almost half a century of retreat, thanks to the explosive growth of the Eurodollar market. International banking, which had remained dormant since the 19

Fenton reaction facilitates organic nitrogen acquisition by an ectomycorrhizal fungus

Boreal trees rely on their ectomycorrhizal fungal symbionts to acquire growth-limiting nutrients, such as nitrogen (N), which mainly occurs as proteins complexed in soil organic matter (SOM). The mechanisms for liberating this N are unclear as ectomycorrhizal fungi have lost many genes encoding lignocellulose-degrading enzymes present in their saprotrophic ancestors. We hypothesized that hydroxyl

Signatures of selection in embryonic transcriptomes of lizards adapting in parallel to cool climate

Populations adapting independently to the same environment provide important insights into the repeatability of evolution at different levels of biological organization. In the 20th century, common wall lizards (Podarcis muralis) from southern and western Europe were introduced to England, north of their native range. Nonnative populations of both lineages have adapted to the shorter season and lo

Rationally Designed Chemically Modified Glycodendrimer Inhibits Streptococcus suis Adhesin SadP at Picomolar Concentrations

Host cell surface carbohydrate receptors of bacterial adhesins are attractive targets in anti-adhesion therapy. The affinity of carbohydrate ligands with adhesins is usually found in the low μm range, which poses a problem for the design of effective inhibitors useful in therapy. In an attempt to increase the inhibitory power of carbohydrate ligands, we have combined the approach of chemical modif

Abnormalities at different levels of the hypothalamic-pituitary-adrenocortical axis early after stroke

BACKGROUND AND PURPOSE: Hypercortisolism is common in stroke patients. The aim of this study was to investigate possible disturbances at different sites within the hypothalamic-pituitary-adrenal axis. We also studied possible associations between hypercortisolism and clinical manifestations of brain dysfunction.METHODS: Patients with an acute ischemic stroke (n = 16; mean +/- SD age, 71 +/- 11 yea

Rescue Effect Inherited in Colony Formation Assays Affects Radiation Response

It is well known that nonirradiated cells can exhibit radiation damage (bystander effect), and recent findings have shown that nonirradiated cells may help protect irradiated cells (rescue effect). These findings call into question the traditional view of radiation response: cells cannot be envisioned as isolated units. Here, we investigated traditional colony formation assays to determine if they

Tracking the picosecond deactivation dynamics of a photoexcited iron carbene complex by time-resolved X-ray scattering

Recent years have seen the development of new iron-centered N-heterocyclic carbene (NHC) complexes for solar energy applications. Compared to typical ligand systems, the NHC ligands provide Fe complexes with longer-lived metal-to-ligand charge transfer (MLCT) states. This increased lifetime is ascribed to strong ligand field splitting provided by the NHC ligands that raises the energy levels of th

High-flux ptychographic imaging using the new 55 μm-pixel detector 'Lambda' based on the Medipix3 readout chip

Suitable detection systems that are capable of recording high photon count rates with single-photon detection are instrumental for coherent X-ray imaging. The new single-photon-counting pixel detector 'Lambda' has been tested in a ptychographic imaging experiment on solar-cell nanowires using Kirkpatrick-Baez-focused 13.8 keV X-rays. Taking advantage of the high count rate of the Lambda and dynami

Removal of pharmaceuticals with ozone at 10 Swedish wastewater treatment plants

Pilot-scale tests were run with ozonation for reduction of 24 pharmaceuticals at 10 full-scale wastewater treatment plants in southern Sweden. Reduction was evaluated based on doses of 3, 5 and 7 g O3/m3 at all plants. The reduction of pharmaceuticals reached on average 65% at 3 g O3/m3, 78% at 5 g O3/m3 and 88% for 7 g O3/m3 in terms of total concentration of pharmaceuticals.

Using Qualitative Content Analysis to Study Consumer Reports on Adverse Drug Reactions

Using qualitative content analysis on adverse drug reactions reports filed to an open Internet-based reporting system in Sweden, this study explored patients’ and consumers’ experiences of antidepressant treatment and the medical encounter. By scrutinizing free text comments in 181 individual consumer reports of adverse drug reactions, we could obtain important information about how people, as indUsing qualitative content analysis on adverse drug reactions reports filed to an open Internet-based reporting system in Sweden, this study explored patients’ and consumers’ experiences of antidepressant treatment and the medical encounter.

Structures of turbulent premixed flames in the high Karlovitz number regime – DNS analysis

Lean premixed turbulent methane-air flames have been investigated using direct numerical simulations (DNS) for different Karlovitz numbers (Ka), ranging from 65 to 3350. The flames are imposed to a high intensity small-scale turbulent environment, corresponding to high Ka conditions, and the effect on the flame structure is investigated during the transition from initial laminar flame to highly di

Mind the gap : The role of mindfulness in adapting to increasing risk and climate change

It is becoming clear that increasingly complex global challenges cannot simply be solved by new technology or governments alone. We also need to develop new social practices and encourage a broader cultural shift towards sustainability. Against this background, this paper explores the role of mindfulness in adapting to increasing risk and climate change. Based on a literature review, it assesses c
