Location, pricing and the problem of Apollonius

In Euclidean plane geometry, Apollonius’ problem is to construct a circle in a plane that is tangent to three given circles. We will use a solution to this ancient problem to solve several versions of the following geometric optimization problem. Given is a set of customers located in the plane, each having a demand for a product and a budget. A customer is satisfied if her total, ...

Curettage schadelijk voor volgende zwangerschap

Dilatatie van de cervix gevolgd door curettage is een gangbare gynaecologische ingreep voor zwangerschapsafbreking of om het bloedverlies bij een miskraam in korte tijd te beëindigen. De ingreep wordt algemeen beschouwd als veilig en complicaties als perforatie van de uterus, infectie of bloeding zijn zeldzaam. Enkele gynaecologen van het AMC ontdekten evenwel dat de ingreep ...

Nonuniform antenna array design by parallelizing three-parent crossover genetic algorithm

Antenna plays a very important role in wireless communication. Array elements laid out nonuniformly could achieve better frequency reliability and lower sidelobe level than uniform spaced elements. Designing desirable nonuniform antenna array requires the tuning of distances between each element, excitation, amplitude, and so on. Such design problem can be solved by genetic ...

Positieve resultaten door gesponsord onderzoek

Wetenschappelijk onderzoek dat gesponsord wordt door de farmaceutische industrie laat vaker een positief resultaat zien dan onderzoek dat niet door de industrie gesponsord wordt. Daarnaast worden de bevindingen in de conclusieparagraaf van artikelen vaker gunstiger omschreven dan bij onderzoek dat op een andere wijze is gefinancierd.

Assessment of Finite Rate Chemistry Large Eddy Simulation Combustion Models

Large Eddy Simulations (LES) of a swirl-stabilized natural gas-air flame in a laboratory gas turbine combustor is performed using six different LES combustion models to provide a head-to-head comparative study. More specifically, six finite rate chemistry models, including the thickened flame model, the partially stirred reactor model, the approximate deconvolution model and the ...

A loss of Pdxk model of Parkinson disease in Drosophila can be suppressed by Buffy

Background The identification of a DNA variant in pyridoxal kinase (Pdxk) associated with increased risk to Parkinson disease (PD) gene led us to study the inhibition of this gene in the Dopa decarboxylase (Ddc)-expressing neurons of the well-studied model organism Drosophila melanogaster. The multitude of biological functions attributable to the vitamers catalysed by this kinase ...

Das fachdidaktische Wissen und Können von Sportlehrpersonen (PCK-Sport)

Das „pedagogical content knowledge“ (PCK) gilt in verschiedenen anderen Schulfächern als zentrale Größe der Professionskompetenz von Lehrpersonen. Für die Sportdidaktik liegen noch sehr wenige Untersuchungen vor. In diesem Beitrag werden die Ergebnisse einer umfangreichen Mixed-Methods-Untersuchung zum fachdidaktischen Wissen und Können von Sportlehrpersonen (PCK-Sport) ...

Therapie nabestaanden voor rouw na moord

Door het verlies van een naaste door moord of doodslag kunnen nabestaanden een emotioneel en traumatisch rouwproces doorlopen. Een onderzoeker aan de Rijksuniversiteit Groningen keek naar de psychopathologie bij nabestaanden van moordslachtoffers en naar het effect van een gecombineerde behandeling van EMDR en cognitieve gedragstherapie.

18F-fluorothymidine PET imaging in gliomas: an update

Brain neoplasms constitute a group of tumors with discrete differentiation grades, and therefore, course of disease and prognosis. Magnetic resonance imaging (MRI) remains the gold standard method for the investigation of central nervous system tumors. However, MRI suffers certain limitations, especially if radiation therapy or chemotherapy has been previously applied. On the other ...

The sustainability of ancient water control techniques in Iran: an overview

Qanats are a traditional source of water management that exists throughout much of the Middle East, and extending into North Africa, Spain and South Asia. In particular, they have played an important role in managing the supply of water throughout Iran for over two millennia in what is an arguably a sustainable manner. With water scarcity playing a prominent role in the modern ...

Actions and Decisions: Pragmatism Gateway to Artful Analytic Management Philosophizing

How management philosophy is conceived depends on if pragmatism is acknowledged or not! After having been under the main domination of management science both research and education has until recently widened its scope from a decision-making to an action-perspective. It seems to be a recent reconnection to pragmatism that makes the 2011 Carnegie report propose to rethink management ...

The kynurenine:tryptophan ratio as a predictor of incident type 2 diabetes mellitus in individuals with coronary artery disease

Aims/hypothesis The tryptophan metabolite kynurenine has potent immune modulatory and vasoactive properties. Experimental data implicate kynurenine in obesity-related morbidities. Epidemiological studies are, however, sparse. We evaluated associations of the plasma and urine kynurenine:tryptophan ratio (KTR) to incident type 2 diabetes. Methods We followed 2519 individuals with ...

Mid-term and long-term safety and efficacy of bioresorbable vascular scaffolds versus metallic everolimus-eluting stents in coronary artery disease: A weighted meta-analysis of seven randomised controlled trials including 5577 patients

Aims Mid- and long-term safety and efficacy of the Absorb bioresorbable vascular scaffold (BVS) have been studied in randomised trials; however, most were not individually powered for clinical endpoints. We performed a weighted meta-analysis comparing mid- and long-term outcomes in patients treated with the BVS compared with the Xience metallic stent. Methods and results Randomised ...

Protecting aquatic biodiversity in Europe: How much do EU environmental policies support ecosystem-based management?

The sustainable management of aquatic ecosystems requires better coordination between policies span-ning freshwater, coastal and marine environments. Ecosystem-based management (EBM) has been promoted as a holistic and integrative approach for the safekeeping and protection of aquatic biodiversity. The paper assesses the degree to which key European environmental policies for the ...

Efficient identification of SNPs in pooled DNA samples using a dual mononucleotide addition-based sequencing method

Identifying single nucleotide polymorphism (SNPs) from pooled samples is critical for many studies and applications. SNPs determined by next-generation sequencing results may suffer from errors in both base calling and read mapping. Taking advantage of dual mononucleotide addition-based pyrosequencing, we present Epds, a method to efficiently identify SNPs from pooled DNA samples. ...

Die Kritik der Politischen Ökonomie der Medien/Kommunikation: ein hochaktueller Ansatz

Dieser Forums-Beitrag diskutiert die Aktualität des Ansatzes einer Kritik der Politischen Ökonomie der Medien/Kommunikation. Er analysiert den Status dieses Feldes, das international eine längere Tradition und Geschichte innerhalb der Medien- und Kommunikationswissenschaft hat. Seit dem Beginn der neuen Krise des Kapitalismus im Jahr 2008 hat das Interesse an Marx generell ...
