This study investigates the impact of supports and synthesis routes on the performance of supported gold nanoparticles in the Sonogashira coupling reaction. The catalysts were synthesized by deposition-precipitation (DP) and incipient wetness impregnation (IMP), employing carriers of different nature (redox: CeO2, TiO2, and non-redox: Al2O3) and were characterized by various physical techniques su
Classification of speed profiles is necessary to allow interpretation of automatic speed measurements in terms of road user behaviour. Aggregation without considering variation in individual profile shapes easily leads to aggregation bias, while classification based on exogenous criteria runs the risk of loosing important information on behavioural (co-) variation. In this paper we test how three
The possibility to reduce dependence on fossil fuel resources has led to an increasing interest in the use of bio-fuels. This study builds on earlier work on (aromatic) cyclic oxygenates [1,2], but a far wider window of engine operation has been investigated in this paper. Two parametric variations of engine operation were performed and discussed: (1) non-EGR operation by means of varying the load
Central Pattern Generators (CPGs) produce rhythmic behaviour across all animal phyla. Cnidarians, which have a radially symmetric nervous system and pacemaker centres in multiples of four, provide an interesting comparison to bilaterian animals for studying the coordination between CPGs. The box jellyfish Tripedalia cystophora is remarkable among cnidarians due to its most elaborate visual system.
High and low pollen deposition years in the period 1998-2010 were recorded for ten forest-forming trees in Roztocze (SE Poland) using Tauber-style traps. The coincidence of very high/low pollen deposition years recorded in Tauber traps and aerobiological data obtained by volumetric samplers shows that these phenomena occur simultaneously in different places across vast areas of a tree's distributi
Angular correlations between unidentified charged trigger (t) and associated (a) particles are measured by the ALICE experiment in Pb-Pb collisions at root s(NN) = 2.76 TeV for transverse momenta 0.25 < p(T)(t,a) < 15 GeV/c, where p(T)(t) > p(T)(a). The shapes of the pair correlation distributions are studied in a variety of collision centrality classes between 0 and 50% of the total hadronic cros
Objective To investigate if the prediction of malignant adnexal masses can be improved by considering different ultrasound-based subgroups of tumors and constructing a scoring system for each subgroup instead of using a risk estimation model applicable to all tumors. Methods We used a multicenter database of 1573 patients with at least one persistent adnexal mass. The masses were categorized into
Urinary cadmium (U-Cd) sampling can be done either by 24-h urine or spot urine sampling, and adjustment for dilution is usually needed. The choice of sampling period and adjustment technique could, however, potentially induce bias. The aim of the study was to compare 24-h urine and spot urine sampling and two dilution adjustment techniques, when assessing U-Cd. Separate 24-h urine (U24) and timed
To identify markers of non-response to neoadjuvant chemotherapy (NAC) that could be used in the adjuvant setting. Sixteen pathologists of the European Working Group for Breast Screening Pathology reviewed the core biopsies of breast cancers treated with NAC and recorded the clinico-pathological findings (histological type and grade; estrogen, progesterone receptors, and HER2 status; Ki67; mitotic
BACKGROUND: Sexual reproduction entails the encounter of the sexes and the multiplicity of rituals is parallel to the diversity of mating systems. Evolutionary mechanisms such as sexual selection and sexual conflict have led to the elaboration of traits to gain attention and favours from potential partners. A paradox exists about how coordinated systems can evolve and diverge when there would seem
A distinguishing component of the mortgage bond market in Denmark is the option to prepay a loan before its maturity date. From the debtors perspective, this is often done with the purpose of refinancing to a lower lending rate. Thus, interest rate modelling becomes a natural part of the pricing process of Danish callable mortgage bonds. Today, yield curves are modelled and thought of differently
The problem of pricing American stock options is far more complex than pricing European options due to the possibility of early execution. This feature means that the decision to either hold on to the option or exercising it early must be continually evaluated, leading to closed form solutions such as the Black-Scholes Formula to not be applicable on American options written on dividend paying ass
IKEA, a company well known around the world for their furniture, is also keen on using digital solutions to improve the customer experience. One of these solutions is the self-serving kiosk, a 27" touchscreen, that helps the customers find and buy products. As many other companies of similar size, IKEA wants to use the data from their digital solutions, as a base for some of their decision ma
The blue economy emerged as sustainable, inclusive and equitable alternative to traditional oceans economy. However, the current paradigm of oceans as development spaces has led to an acceleration of competing uses of marine resources causing ecosystem deterioration and human rights abuses that disproportionately affect vulnerable small-scale fisheries. Blue justice movements seek to reconcile env

Sony Corporation is the company responsible for the Sony Group's Electronics Products and Solutions business. Sony Corporation has developed a system, Visilion Care, for healthcare real-time positioning and analytics of equipment, to help personnel and management s
For someone who has undergone an amputation, it is important to be able to decide what the prosthesis should look like. Since many people today choose to have some sort of cover on their prosthesis, either to fill the void or to regain the feeling of a leg, it is very important that it is something that the user feels comfortable with. To go through an amputation is often a very shocking event
