City Typology, for context-sensitive framework and tools development

In order to better understand the factors that hinder SUMP development and address urban mobility challenges, CIVITAS SUMP-PLUS is working within six co-creation laboratories in six cities. Yet due to the varying circumstances and mobility contexts in the project’s partner and (more generally) European cities, SUMP-PLUS determined the need for a city typology that enables the comparison of and the identification of differences between these varied city contexts. This report delivers an overview of the sources and methods used by different organisations, projects and other institutions when creating city typologies. Finally, this report sets out SUMP-PLUS’s own mobility-focused city typology, whose development has drawn on the aforementioned city typologies

DevOps Adoption Benefits and Challenges in Practice: A Case Study

DevOps is an approach in which traditional software engineering roles are merged and communication is enhanced to improve the production release frequency and maintain software quality. There seem to be benefits in adopting DevOps but practical industry experiences have seldom been reported. We conducted a qualitative multiple-case study and interviewed the representatives of three software development organizations in Finland. The responses indicate that with DevOps, practitioners can increase the frequency of releases and improve test automation practices. DevOps was seen to encourage collaboration between departments which boosts communication and employee welfare. Continuous releases enable a more experimental approach and rapid feedback collection. The challenges include communication structures that hinder cross-department collaboration and having to address the cultural shift. Dissimilar development and production environments were mentioned as some of the technical barriers. DevOps might not also be suitable for all industries. Ambiguity in the definition of DevOps makes adoption difficult since organizations might not know which practices they should implement for DevOps.Peer reviewe

Effect of dietary intervention on serum lignan levels in pregnant women - a controlled trial

<p>Abstract</p> <p>Background</p> <p>Mother's diet during pregnancy is important, since plant lignans and their metabolites, converted by the intestinal microflora to enterolignans, are proposed to possess multiple health benefits. Aim of our study was to investigate whether a dietary intervention affects lignan concentrations in the serum of pregnant women.</p> <p>Methods</p> <p>A controlled dietary intervention trial including 105 first-time pregnant women was conducted in three intervention and three control maternity health clinics. The intervention included individual counseling on diet and on physical activity, while the controls received conventional care. Blood samples were collected on gestation weeks 8-9 (baseline) and 36-37 (end of intervention). The serum levels of the plant lignans 7-hydroxymatairesinol, secoisolariciresinol, matairesinol, lariciresinol, cyclolariciresinol, and pinoresinol, and of the enterolignans 7-hydroxyenterolactone, enterodiol, and enterolactone, were measured using a validated method.</p> <p>Results</p> <p>The baseline levels of enterolactone, enterodiol and the sum of lignans were higher in the control group, whereas at the end of the trial their levels were higher in the intervention group. The adjusted mean differences between the baseline and end of the intervention for enterolactone and the total lignan intake were 1.6 ng/ml (p = 0.018, 95% CI 1.1-2.3) and 1.4 ng/mg (p = 0.08, 95% CI 1.0-1.9) higher in the intervention group than in the controls. Further adjustment for dietary components did not change these associations.</p> <p>Conclusion</p> <p>The dietary intervention was successful in increasing the intake of lignan-rich food products, the fiber consumption and consequently the plasma levels of lignans in pregnant women.</p> <p>Trial registration</p> <p><b>ISRCTN21512277, <url>http://www.isrctn.org</url></b></p

Reductive Amination of Ketones with Benzylamine Over Gold Supported on Different Oxides

Reductive amination of cyclohexanone with benzylamine was investigated at 100 °C under 30 bar hydrogen in toluene with five different gold catalysts prepared by deposition–precipitation method and supported on TiO2, La2O3/TiO2, CeO2/TiO2, La2O3 and CeO2. Size of metallic gold varied in the range of 2.6–3.6 nm. The best catalysts in reductive amination of cyclohexanone with benzylamine were 4 wt% Au/TiO2 and 4 wt% Au/CeO2/TiO2 giving 72% and 79% yield of the desired amine. The most acidic and basic catalysts were also unselective and exhibited low activity towards imine hydrogenation. The best catalyst 4 wt% Au/CeO2/TiO2 gave in reductive amination of propiophenone 56% selectivity to the corresponding amine at 20% conversion in 5 h.</p

Tracing Medieval and Renaissance Alabaster Works of Art Back to Quarries: A Multi-Isotope (Sr, S, O) Approach

Multi-isotope fingerprinting (sulphur, oxygen and strontium isotopes) has been tested to study the provenances of medieval and Renaissance French and Swedish alabaster works of art. Isotope signatures of historical English, French and Spanish alabaster source quarries or areas are revealed to be highly specific, with a strong intra-group homogeneity and strong inter-group contrasts, especially for Sr and S isotopes. The chosen combination of isotope tracers is a good basis for forensic work on alabaster provenance, allowing verification of hypotheses about historical trade routes as well as identification of fakes and their origin. The applied analytical techniques of continuous flow isotope ratio mass spectrometry (CF–IRMS) and thermal ionization mass spectrometry (TIMS) only require micro-samples in the low-milligram range, thus minimizing the impact on the works of art

Gene expression differences between stroke-associated and asymptomatic carotid plaques

Atherosclerotic carotid stenosis is an important risk factor for stroke. Carotid plaques (CPs) causing stroke may present a distinct type of molecular pathology compared with transient ischemic attack (TIA)-associated or asymptomatic plaques. We compared the gene expression profiles of CPs from stroke patients (n = 12) and asymptomatic patients (n = 9), both with similar risk factors and severity of carotid stenosis (>70%). Sixty probes showed over 1.5-fold expression difference at 5% false discovery rate. Functional clustering showed enrichment of genes in 51 GO categories and seven pathways, the most significant of which relate to extracellular-matrix interaction, PPAR gamma signaling, scavanger receptor activity, and lysosomal activity. Differential expression of ten genes was confirmed in an extended replication group (n = 43), where the most significant expression differences were found in CD36 (2.1-fold change, p = 0.005), CD163 (1.7-fold change, p = 0.007) and FABP4 (2.2-fold change, p = 0.015). These include four genes not previously linked to plaque destabilization: GLUL (2.2-fold change, p = 0.016), FUCA1 (2.2-fold change, p = 0.025), IL1RN (1.6-fold change, p = 0.034), and S100A8 (2.5-fold change, p = 0.047). Strong correlations were found to plaque ulceration, plaque hemorrhage, and markers of apoptosis and proliferation (activated caspase 3, TUNEL, and Ki67). Protein expression of these genes was confirmed by immunohistochemistry and was found in the atheromatous areas of CPs critical for plaque destabilization. This study presents a comprehensive transcriptional analysis of stroke-associated CPs and demonstrates a significant transcriptome difference between stroke-associated and asymptomatic CPs. Follow-up studies on the identified genes are needed to define whether they could be used as biomarkers of symptomatic CPs or have a role in plaque destabilization
