This paper summarizes the second part of a study over a two year period carried out at the Laboratory for Fuel Technology and Heat Transfer of the University of Gent in cooperation with Dow Benelux N.V.. The first part of the study, focusing on the effects of cone calorimeter test variables as well as polyurethane (PU) flexible foam variables on the foam combustion characteristics, has been publis

The relative contributions of fabric and foam on important fire hazard parameters as measured in the cone calorimeter were determined for various mock-up combinations. Three commercial types of high resilience PU flexible slabstock foams, representing a wide range of combustion performance, were combined with three different fabrics; viz. polyester, polypropylene and combustion modified cotton. To

The first part of this study focused on the effect of cone calorimeter test variables on polyurethane flexible foam properties such as ignitability, heat release rate, effective heat of combustion and mass loss. Three of the main commercial foam types were used; viz. conventional slabstock foams, high resilience slabstock foams and all-MDI moulded foams. A decrease in heat flux (down to 40%) with

Based on a review of studies of functional and comparative anatomy of crustacean eyes, a hypothesis is formed on eyes in primitive crustaceans. It is suggested that they were similar to present-day frontal eyes of the malacostracan type. Neuronal architecture suggests that the development to apposition compound eye followed two main routes, one seen in malacostracansand the other in non-malacostra

The digestive tract of the cephalocarid Hutchinsoniella macracantha begins with an atrium oris, posterior to the mouth. The esophagus loops up through the head and ends with a valve to the midgut. The epithelial cells and cuticle of both these structures are connected with long, winding, apically distended microvilli. The midgut is a straight tube with a pair of diverticula anteriorly. Midgut epit

Immunoreactivity to antisera raised against scrotonin, a biogenic amine, and FMRFamide, a neuropeptide, reveals two different populations of neurons in the nervous system of Hutchinsoniella macracantha. Neural transmission may thus use at least transmitter substances that are found in other crustaceans and invertebrates.

The structure of the aesthetascs has been investigated in the prawn Macrobrachium rosenbergii (larvae and juveniles), the opossum shrimp Neomysis integer, the euphausid Meganyctiphanes, and in the water-fleas Daphnia magna and D. longispina. The aesthetascs, that are thought to represent olfactory receptors, exhibit a considerable structural variation, ranging from the well known aesthetascs of hi

The primary excretory organ of adult Hutchinsoniella macracantha is the maxillary gland, which is located laterally in the posterior portion of the cephalon. It consists of an end sac and a tubule which is divided into proximal and distal sections. The end sac is composed of podocytes filled with endocytotic vesicles which grade in size upward to a large residual body. A large valve controls the o

The first antenna of Hutchinsoniella macracantha is a 6-segmented, uniramous appendage carrying 1 aesthetasc and 22 setae (or sensilla). The second antenna is biramous and has approximately 80 setae. The sensory cells of the first antenna are arranged in 3 clusters in the first and second segments; one cluster serving the aesthetasc (approximately 130 cells), one the 11 setae of the sixth segment

Eye-tracking research in infants and older children has gained a lot of momentum over the last decades. Although eye-tracking research in these participant groups has become easier with the advance of the remote eye-tracker, this often comes at the cost of poorer data quality than in research with well-trained adults (Hessels, Andersson, Hooge, Nyström, & Kemner Infancy, 20, 601-633, 2015; Was

Treatment with pancreatic or pancreatic-like microbial enzymes during the suckling period has positive effects on the gut, resulting in a better fat absorption and improved barrier function in pigs. The present study investigated the effects of pancreaticlike enzyme treatment during the pre- or postweaning period on pig growth and nitrogen utilization. Suckling 7- to 14-d-old pigs were gavage fed

Correct reproductive timing is crucial for fitness. Breeding phenology even in similar species can differ due to different selective pressures on the timing of reproduction. These selection pressures define species' responses to warming springs. The temporal match-mismatch hypothesis suggests that timing of breeding in animals is selected to match with food availability (synchrony). Alternatively,

It is well known that during the suckling period pancreatic secretion is low. The aim of the study was to investigate the effects of dietary supplementation with pancreatic-like enzymes of microbial origin (PLEM) and SiO2, as an antibacterial factor, on the performance of piglets fed creep feed during weaning and thereafter. The experiment was performed on piglets from 30 litters. The piglets were

The wine and beer yeast Dekkera bruxellensis thrives in environments that are harsh and limiting, especially in concentrations with low oxygen and high ethanol. Its different strains' chromosomes greatly vary in number (karyotype). This study isolates two novel centromeric loci (CEN1 and CEN2), which support both the yeast's autonomous replication and the stable maintenance of plasmids. In the seq

Resistance to life-saving antibiotics increases rapidly worldwide, and multiresistant bacteria have become a global threat to human health. Presently, the most serious threat is the increasing spread of Enterobacteriaceae carrying genes coding for extended spectrum β-lactamases (ESBL) and carbapenemases on highly mobile plasmids. We here demonstrate how optical DNA maps of single plasmids can be u

Due to advances in technology the amount of images from portable cameras has increased tremendously in recent years. Nowadays, most new mobile phones and cars have multiple cameras. Drones and other robots are often equipped with cameras as well. To be able to capture an image is not the same as to understand the content of it. Computer vision deals with the task of giving machines the ability to

Introduction: Human papillomavirus (HPV) infection is an objective marker with a high sensitivity for finding cervical dysplasia. The objective of the current study is to investigate whether HPV testing, combined with liquid-based cytology, is reliable as a test of cure after the loop electrical excision procedure (LEEP). Material and methods: The LEEP was performed in 330 women for excision of ce
