Growth of bacteria in the rhizoplane and the rhizosphere of rape seedlings

The growth of 10 isolates of rhizosphere bacteria was compared in the rhizoplane (RP), rhizosphere (RS) and non-rhizosphere soil of a model system with rape seedlings growing in sterile sand. The colonization of the RP differed little among isolates. However, the bacterial isolates differed according to their degree of dependence on the root for growth, as judged by RS:RP and plant:non-plant ratio

Precision and sensitivity of the measurement of 15 N enrichment in D-alanine from bacterial cell walls using positive/negative ion mass spectrometry

Sensitive detection of cellular components from specific groups of microbes can be utilized as 'signatures' in the examination of microbial consortia from soils, sediments or biofilms. Utilizing capillary gas chromatography/mass spectrometry and stereospecific derivatizing agents, D-alanine, a component localized in the prokaryotic (bacteria) cell wall, can be detected reproducibly. Enrichments o

Striving for democracy in the nordic context: possibilities for change through innovative cases of activist music practices

In this roundtable we will present three cases of activist music education, in other words innovative and inclusive practices of music education initiated by courageous institutional leaders and teachers in the Finnish and Swedish context. By activism we mean professional thinking and action that strives toward new ways of making change inside and outside educational institutions through four char

Complete regioselective addition of grignard reagents to pyrazine N-oxides, toward an efficient enantioselective synthesis of substituted piperazines

(Figure presented) A conceptually new one-pot strategy for the synthesis of protected substituted piperazines via the addition of Grignard reagents to pyrazine N-oxides is presented. This strategy is high yielding (33-91% over three steps), step-efficient, and fast. The synthesized N,N-diprotected piperazines are convenient to handle and allow for orthogonal deprotection at either nitrogen for sel

Active and Transformational Engagement with Writing Feedback : Using Reflection as a Tool to Access Literary Disciplinary Knowledge

In this article, we explore the importance of feedback on students’ literature essays and challenges in encouraging active and transformational engagement with such feedback. In addition to standard practice of student-centred peer review coupled with feedback from teachers, our model consists of a scaffolded pair of reflection tasks that students are required to complete. Based on a study of 245 This article explores ways of encouraging student engagement with feedback on literature essays. In addition to standard practice of student-centred peer review coupled with feedback from teachers, we have developed a scaffolded pair of reflection tasks on an introductory-level English literature course. With a focus on our two-step model for student self-reflection, this article highlights some c

Can costs of pesticide exposure for bumblebees be balanced by benefits from a mass-flowering crop?

Mass-flowering crops provide forage for bees but also contain pesticides. Such pesticide exposure can harm bees, but our understanding of how this cost is balanced by forage benefits is limited. To provide insights into benefits and costs, we placed bumblebee colonies in 18 landscapes with conventional red clover fields treated with the neonicotinoid thiacloprid (flowers + pesticide), untreated or

A correlation-hole approach to the electric double layer with counter-ions only

We study a classical system of identically charged counter-ions near a planar wall carrying a uniform surface charge density. The equilibrium statistical mechanics of the system depends on a single dimensionless coupling parameter. A new self-consistent theory of the correlation-hole type is proposed which leads to a modified Poisson–Boltzmann integral equation for the density profile, convenient

The National Early Warning Score (NEWS) - Testing and evaluation in a Swedish setting

BackgroundDeviating vital signs have been known to precede Serious Adverse Events (SAEs) like In-Hospital Cardiac Arrest (IHCA), unplanned Intensive Care Unit (ICU) admission or unexpected death for more than a decade but still the recognition of these deteriorating patients is poor.The British National Early Warning Score (NEWS) is a ‘‘track and trigger’’ scale designed to assess in-hospital patiBackgroundDeviating vital signs have been known to precede Serious Adverse Events (SAEs) like In-Hospital Cardiac Arrest (IHCA), unplanned Intensive Care Unit (ICU) admission or unexpected death for more than a decade but still the recognition of these deteriorating patients is poor.The British National Early Warning Score (NEWS) is a ‘‘track and trigger’’ scale designed to assess in-hospital pati

Methylation of human eukaryotic elongation factor alpha (eEF1A) by a member of a novel protein lysine methyltransferase family modulates mRNA translation

Many cellular proteins are methylated on lysine residues and this has been most intensively studied for histone proteins. Lysine methylations on non-histone proteins are also frequent, but in most cases the functional significance of the methylation event, as well as the identity of the responsible lysine (K) specific methyltransferase (KMT), remain unknown. Several recently discovered KMTs belong

Genome-wide association and Mendelian randomisation analysis provide insights into the pathogenesis of heart failure

Heart failure (HF) is a leading cause of morbidity and mortality worldwide. A small proportion of HF cases are attributable to monogenic cardiomyopathies and existing genome-wide association studies (GWAS) have yielded only limited insights, leaving the observed heritability of HF largely unexplained. We report results from a GWAS meta-analysis of HF comprising 47,309 cases and 930,014 controls. T

Kan religiösa handlingar vara rationella för en ateist?

According to a popular view, religious fictionalism requires the atheist subject to have independent motivation/justification for all of her religious actions. I challenge this view and argue that all that is needed is a holistic justification of the subject's fictionalist engagement with religion.

Crizotinib and PARP inhibitors act synergistically by triggering apoptosis in high-grade serous ovarian cancer

High-grade serous ovarian cancer (HGSOC) is the predominant and most lethal histological type of epithelial ovarian cancer. During the last few years, several new treatment options with PARP inhibitors have emerged. The FDA has approved the PARP inhibitor olaparib (Lynparza™) as maintenance treatment after first-line platinum-containing chemotherapy and olaparib, niraparib (Zejula™) and rucaparib

Late glacial and Holocene sand drift in south-central Sweden: sediments and ages

The aeolian deposits of Sweden have received modest attention, despite their usefulness as a palaeoenvironmental archive. Here we present sedimentological information and optically stimulated luminescence (OSL) ages from inland sand dunes in the lowlands of south-central Sweden. Three main lithofacies, each with two subfacies, were identified in the deposits: massive sand, laminated sand and cross
