The effect of osmo-induced stress on product formation by Zymomonas mobilis on sucrose
2000
The intensification of biosynthesis of fructooligosaccharides in the presence of high salt concentrations was observed during sucrose (10%) fermentation by Zymomonas mobilis 113S. A 0.6 M NaCl concentration led to an increase of oligosaccharide productivity by 3.5-fold. Sorbitol formation was increased in the presence of 0.16 M NaCl and was inhibited at highest salt concentrations. In a medium with high (65%, w/w) sucrose content the salts gave inhibitory effects on fructooligosaccharide production by lyophilised Z. mobilis cells. Influence of salts on gluconic acid and sorbitol formation under these conditions was studied. The ratio of oligosaccharides and gluconic acid productivity (Qolig…
Coordination complexes of chromium(0) with a series of 1,3-diphenyl-6-arylfulvenes
2018
The synthesis and structural properties of a series of chromium tricarbonyl `piano-stool' complexes bearing substituted pentafulvene ligands were studied. The complexes, tricarbonyl(1,3,6-triphenylfulvene)chromium(0) benzene hemisolvate, [Cr(C24H18)(CO)3]·0.5C6H6 (I), tricarbonyl[1,3-diphenyl-6-(3-vinylphenyl)fulvene]chromium(0), [Cr(C26H20)(CO)3] (II), and tricarbonyl[1,3-diphenyl-6-(pyren-1-yl)fulvene]chromium(0), [Cr(C34H22)(CO)3] (III), each have a distorted octahedral geometry, with the fulvene coordinated in a π–η2:π–η2:π–η2 fashion. Significant deviation of the exocyclic fulvene double bond from the cyclopentadiene plane accompanies coordination. Evidence of non-covalent π–π interact…
Mathematics teachers and digital tools
2016
International audience; This chapter considers mathematics teachers’ appropriation and classroom use of digital tools. The first section considers teachers—who are they, how are they conceived in the literature and what aspects of teachers have been studied? The second section examines twenty-first century research on mathematics teachers using digital tools. This sheds light on the complexity of mathematics teachers’ appropriation and classroom use of digital tools but what we find is that our focus is too narrow and we need to consider digital tools within the range of resources use in planning and realising their lessons, which leads us to the third section, mathematics teachers using re…
Improving quality in clinical placement studies in nursing homes (QUALinCLINstud):the study protocol of a participatory mixed methods multiple case s…
2020
IntroductionImproved quality in clinical supervision and assessment of student nurses in nursing home clinical placements is vitally important to effective recruitment and preparation for this healthcare sector. Knowledge regarding supervision and assessment practices within these settings is limited. Also, knowledge of evolving e-learning tools on the quality and effectiveness of these educational practices seems to be absent.Methods and analysisThe aim of the “Improving quality in clinical placement studies in nursing homes” (QUALinCLINstud) study is to develop and evaluate how a web-based programme can optimise supervision, assessment and learning during nursing home placements. The stud…
Voluntary Imitation in Alzheimer’s Disease Patients
2016
International audience; Although Alzheimer's disease (AD) primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients' behavior. The aim of the present study was to investigate whether voluntary motor imitation, i.e.…
Competition Advocacy: Soft Power in Competitive Policy
2013
Abstract Changing market conditions stimulate modernization of criteria, norms and standards of competition regulation and methods of enforcement. Competition advocacy is a type of activity exercised by antimonopoly authorities to strengthen competitive environment without enforcement measures, through developing active cooperation with other government bodies and increasing the degree of understanding of the benefits of competition by the community.
Assessing the Economy for the Common Good Measurement Theory Ability to Integrate the SDGs into MSMEs
2020
Over the past decades, sustainability and corporate sustainability have gained a lot of attention. Currently, the focus of attention has shifted to the integration of the Sustainable Development Goals (SDGs) into businesses operation. The extant literature points to the proposed frameworks as not fitting micro, small, and medium-sized enterprises (MSME) reality and, also, to a lack of empirical evidence in this field. With research at the intersection of business and SDGs still being scarce, the Economy for the Common Good (ECG) model allows operationalizing the SDGs employing its novel measurement theory. The present study is aimed at completing the statistical validation process of the EC…
Accuracy of risk tools to predict critical bleeding in major trauma: A systematic review with meta-analysis.
2021
BACKGROUND Early detection of critical bleeding by accurate tools can help ensure rapid delivery of blood products to improve outcomes in major trauma patients. We conducted a systematic review to evaluate the accuracy of risk tools to predict critical bleeding in patients with major trauma. METHODS PubMed, Embase, and CENTRAL were searched up to February 2021 for studies investigating risk tools to predict critical bleeding for major trauma people in prehospital and emergency department. We followed the Preferred Reporting Items for Systematic Review and Meta-Analysis of Diagnostic Test Accuracy study guidelines. Two independent authors included studies, extracted data, appraised the quali…
Teaching master's degree students to read research literature
2017
The skill to read research literature critically belongs in every university graduate’s toolbox. I have attempted to teach this skill in a master’s degree level course in programming languages over 15 years using, at various times, simulated conferences, voluntary reading exercises, evidence-based practice training, and a flipped classroom with mandatory reading assignments. I discuss my experience and analyze preliminary qualitative data on the use of evidence-based practice and a flipped classroom for this purpose. I present no firm conclusions, but expect that future work (by me or others) will be able to use my experience as a baseline for better teaching of research literature reading.…
TEACHING ACTIVITY AND EVALUATION OF CRITICAL THINKING IN PRIMARY SCHOOL
2019
The aim of this work is to verify the efficacy of a training program focused on the enhancement of critical thinking skills, realized with a group of children between the ages of 9 and 11 years, in the last year of primary school in the Palermo area. At school as in life, critical thinking skills are fundamental; these skills concern above all the integrated processing of information, the correct use of reasoning, the adequate formulation of judgments, the taking of autonomous and controlled choices. Technological expansion fuels the children and young people’s difficulties to organize the knowledge data, coming from several sources, in a coherent and logical way as well as to evaluate info…
