In this article the effect of ideological changes in political parties (catch-all process) and in their recruitment patterns (professionalization) on the party affiliation of working-class politicians is investigated in Belgium, both for Members of Parliament (MPs) and for candidates. The disappearance of the link between the working class and social-democratic parties due to enlargement of the parties' focus coincides with a decline in formal ...

Flash thermography is a promising technique to perform quick and non-contact non-destructive testing of composite materials. However, several limitations such as non-uniform heating and lateral heat diffusion complicate the accurateness of this technique. This paper presents an experimental case study of flash thermography for the non-destructive testing of a CFRP component of an aircraft with production defects. Three post-processing ...

Practically it is extremely difficult to collect observations following a fully sound statistical design, typically encompassing a high number of repetitions, of an intensive and elaborate experimental procedure such as flash pyrolysis reactor experiments. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) is an extremely useful analytical technique in order to simulate a high number of repetitive pyrolysis experiments in an acceptable ...

The valorization of raspberry seed cake by flash and slow pyrolysis is investigated in this study. During flash pyrolysis, temperature significantly affects the yield and properties of the products. The highest liquid yield (53.6 wt%) is found at 450 degrees C. This liquid has a water content (26.2 wt%), a HHV (18.6 MJ/kg) and a pH-value (3.2) that are comparable to those of pyrolysis liquids produced by flash pyrolysis of lignocellulosic ...

Flash floods in the Sinai often cause significant damage to infrastructure and even loss of life. In this study, the susceptibility to flash flooding is determined using hydro-morphometric characteristics of the catchments. Basins and their hydro-morphometric features are derived from a digital elevation model from NASA Earthdata. Principal component analysis is used to identify principal components with a clear physical meaning that explains ...

The disposal problem associated with phytoextraction of farmland polluted with heavy metals by means of willow requires a biomass conversion technique which meets both ecological and economical needs. Combustion and gasification of willow require special and costly flue gas treatment to avoid re-emission of the metals in the atmosphere, whereas flash pyrolysis mainly results in the production of (almost) metal free bio-oil with a relatively high ...

The increased use of complex and holistic modelling for multi-hazard analysis is in sharp contrast with a lacuna in hazard analysis in equatorial Africa. This study aims to increase understanding of multi-hazard events in poorly documented regions with lowaccessibility.We focus on the Nyamwamba catchment (107 km2) located in the Rwenzori Mountains (Uganda)
where on May 1, 2013, a severe flash flood occurred. In this region, wildfires, ...

A high water content is one of the major drawbacks for the utilisation of bio-oil. One technology which shows the potential to satisfy the demand for bio-oil with a reduced water content is the flash co-pyrolysis of biomass with biopolymers. The influence of biopolymers on the pyrolysis yield of a biomass waste stream is investigated with a semi-continuous home-built pyrolysis reactor. Polylactic acid (PLA), corn starch, polyhydroxybutyrate ...

Short rotation coppice (SRC) seems attractive as an energy crop on degraded land. Gasification and flash pyrolysis are promising technologies for the conversion of SRC into energy or chemicals. A model has been developed to calculate the net present value (NPV) of the cash flows generated by an investment in gasification or flash pyrolysis of SRC for the production of electricity or for combined heat and power production. The NPV has been ...

Printable cement paste should be easy to convey in pipelines and well set in a short period of time after extrusion. Mixing flash setting admixture into cement paste at the printer mozzle is a potential way to achieve this goal. The mixed in flash setting admixture can speed up the hydration process, leading to a faster stiffening of the printed cement paste. In this study, several batches of cement paste with flash setting admixture dosages of ...
