Weak habitat specificity in ectomycorrhizal communities associated with Salix herbacea and Salix polaris in alpine tundra

This study explores mid-alpine ectomycorrhizal communities on Salix herbacea and Salix polaris in plant communities differing in nutrient status and snow conditions. Plant species were identified by tracking roots back to above ground structures while fungal species were identified using molecular methods. The fungi were identified to 34 molecular operational taxonomic units (MOTUs)/species but sp

Motstånd, moral och medarbetarinflytande vid förändringsarbete i offentlig sektor

Personalmotstånd anges ofta som ett problem vid förändringsarbete. I forskningen utgår man gärna från att motståndet beror på emotionella faktorer och man bortser från motståndets faktiska innehåll. I detta papper står detta innehåll i fokus och motstånd tolkas som en begäran om inflytande i ledningens beslutsfattande, med avseende på förändringen. Här väljer ledningen en strategi, som vid förändr

RF strip-line anodes for Psec large-area MCP-based photodetectors

We have designed and tested economical large-area RF strip-line anodes made by silk-screening silver onto inexpensive plate glass, for use in microchannel plate photodetectors to provide measurements of time, position, integrated charge, and pulse waveform shapes. The 229-mm-long anodes are modular, and can be attached in series for economy in electronics channel-count. Measurements of the anode i

A deepwater fish with 'lightsabers' - dorsal spine-associated luminescence in a counterilluminating lanternshark

We report the discovery of light organs (photophores) adjacent to the dorsal defensive spines of a small deep-sea lanternshark (Etmopterus spinax). Using a visual modeling based on in vivo luminescence recordings we show that this unusual light display would be detectable by the shark's potential predators from several meters away. We also demonstrate that the luminescence from the spine-associate

Identification of an NADH-dependent 5-hydroxymethylfurfural-reducing alcohol dehydrogenase in Saccharomyces cerevisiae.

We report on the identification and characterization of a mutated alcohol dehydrogenase 1 from the industrial Saccharomyces cerevisiae strain TMB3000 that mediates the NADH-dependent reduction of 5-hydroxymethylfurfural (HMF) to 2,5-bis-hydroxymethylfuran. The co-factor preference distinguished this alcohol dehydrogenase from the previously reported NADPH-dependent S. cerevisiae HMF alcohol dehydr

Design and Implementation of Distributed Resource Management for Time Sensitive Applications

In this paper, we address distributed convergence to fair allocations of CPU resources for time-sensitive applications. We propose a novel resource management framework where a centralized objective for fair allocations is decomposed into a pair of performance-driven recursive processes for updating: (a) the allocation of computing bandwidth to the applications (resource adaptation), executed by t

Clinical dosimetry in the treatment of bone tumors: old and new agents

Treatment of multisite, sclerotic bone metastases is successfully performed by radionuclide therapy. Pain palliation is the most common aim for the treatment. Two radiopharmaceuticals are currently approved by the European Medicines Agency (Sm-153-EDTMP and Sr-89-Cl-2) whilst other radiopharmaceuticals are at different stages of development, or are approved in some European countries (Re-186-HEDP,

Relation between Seasonally Detrended Shortwave Infrared Reflectance Data and Land Surface Moisture in Semi-Arid Sahel

In the Sudano-Sahelian areas of Africa droughts can have serious impacts on natural resources, and therefore land surface moisture is an important factor. Insufficient conventional sites for monitoring land surface moisture make the use of Earth Observation data for this purpose a key issue. In this study we explored the potential of using reflectance data in the Red, Near Infrared (NIR), and Shor

The Soft Tissues in Osteoarthritis and Arthroplasty of the Hip

Ultrasonography as a tool measuring the anterior capsular distance in THA was so far not described nor validated. Comparing the measurements of the capsular distance set with a caliper/ruler with those performed with ultrasonography on a THA model demonstrated a high correlation between measurements. The effect of experience of ultrasonography in THA was also evaluated comparing the first and last

Bis(benzimidazolyl)amine copper complexes with a synthetic 'histidine brace' structural motif relevant to polysaccharide monooxygenases

Reaction of Cu2+ salts with the benzimidazole-N-methylated bis[(1-methyl-2-benzimidazolyl)ethyl]amine ligand 2BB results in either bi- or monometallic complexes. Spectroscopic and solid state characterization reveals either square pyramidal or trigonal bipyramidal coordination geometries around the cupric ions. In [{2BBCu(mu-F)}(2)](BF4)(2), the dicopper structure is determined by the bridging nat

Physiological heterogeneities in microbial populations and implications for physical stress tolerance

Background: Traditionally average values of the whole population are considered when analysing microbial cell cultivations. However, a typical microbial population in a bioreactor is heterogeneous in most phenotypes measurable at a single-cell level. There are indications that such heterogeneity may be unfavourable on the one hand (reduces yields and productivities), but also beneficial on the oth

The illusion of totality: a critical discourse analysis on the identity of Japanese bureaucrats inside and outside of the ministries

The collective identity is subject to permanent negotiation. Due to the lack of incentive to offer public statements, the collective identity of Japanese bureaucrats (or kanryo, 官僚) has been constructed separately inside and outside of the ministries. This paper explores how the collective identity of kanryo has been constructed in two Japanese national newspapers as outsider discourses using stru

Folate - Associations with breast cancer depending on intake, metabolism, genetic variation and estrogen receptor status.

Popular Abstract in Swedish Folat är ett B-vitamin som kan bidra till minskad risk för en rad sjukdomar, däribland en speciell form av blodbrist, ryggmärgsbråck hos nyfödda, hjärt- kärlsjukdom och vissa cancerformer. Folat förekommer framför allt i många vegetabiliska livsmedel. Speciellt höga halter har gröna bladgrönsaker, baljväxter (t.ex. kikärtor) och lever. Betydande folatkällor i svensk koFolate is a B-vitamin that may influence cancer development via its role as methyl donor for DNA synthesis and methylation. Plant foods contain many bioactive compounds including folate and fiber. Results from the Malmö Diet and Cancer (MDC) cohort indicate lower breast cancer risk at high fiber intake. Folate intake may partly explain this association. Aims of this thesis were to examine if i

The structure of superantigen complexed with TCR and MHC reveals novel insights into superantigenic T cell activation

Superantigens (SAgs) are bacterial toxins that interact with immunoreceptors, T cell receptor (TCR) and major histocompatibility complex (MHC) class II, conventionally through the variable beta-domain of TCR (TCRV beta). They induce a massive release of cytokines, which can lead to diseases such as food poisoning and toxic shock syndrome. In this study, we report the X-ray structure of the ternary

IL6 genotype, tumour ER-status, and treatment predicted disease-free survival in a prospective breast cancer cohort.

In breast cancer, high levels of the inflammatory cytokine interleukin-6 (IL-6) have been associated with disease-free survival and treatment resistance. Increased serum levels of IL-6 have been correlated with increased levels of NF-κβ and aromatase expression in adipose tissue. Several IL6 single nucleotide polymorphisms have been associated with breast cancer prognosis, but the impact may diffe

Recent advances in semiconductor nanowire heterostructures

Semiconductor nanowires have made a deep impact on materials science related research, and are being explored for applications in several disciplines. Many of these applications require heterostructures, which can be defined as the combination of two or more materials within the same nanowire structure. In this paper we briefly review the current state-of-the-art concerning epitaxial nanowire hete
