Infrared dryers, both gas fired and electrically healed, have become a widespread technology in the paper industry. This work proposes a model for the absorption of thermal radiation in the thickness direction of a paper sheet. The model is based on the multilayer idealization of a paper sheet proposed by Scallan and Porch. In this model, the optical properties of paper are considered as the resul

Group G streptococcus (GGS) is a human bacterial pathogen expressing surface proteins FOG and protein G (PG) which interact with several host defense systems, including the complement and contact systems. Selected reaction monitoring mass spectrometry, electron microscopy, and protein binding assays were used to follow the amounts of FOG and PG intracellularly and on the bacterial surface during d

Knowledge of the processes favouring the establishment of exotic parasites is poor. Herein, we test the characteristics of successful exotic parasites that have co-established in the remote island archipelago of New Zealand, due to the introduction of numerous avian host species. Our results show that avian malaria parasites (AM; parasites of the genus Plasmodium) that successfully invaded are mor

The electronic structure of free aluminum clusters with similar to 3-4 nm radius has been investigated using synchrotron radiation-based photoelectron and Auger electron spectroscopy. A beam of free clusters has been produced using a gas-aggregation source. The 2p core level and the valence band have been probed. Photoelectron energy-loss features corresponding to both bulk and surface plasmon exc

Microfocal spectroscopic ellipsometry mapping of the electronic properties and thickness of epitaxial graphene grown by high-temperature sublimation on 3C-SiC (111) substrates is reported. Growth of one monolayer graphene is demonstrated on both Si- and C-polarity of the 3C-SiC substrates and it is shown that large area homogeneous single monolayer graphene can be achieved on the Si-face substrate

The agro-climatic resources of Cameroon are examined in light of the potential for food crop production and challenges presented by climate change. We find that the diversity of Cameroon's agro-climate offers the potential for the cultivation of a variety of food crops. This feature of Cameroonian agriculture can be used in addressing the country's adaptive capacity to climate change. However, the

Multi-step synthetic pathways to low-ion exchange capacity (IEC) polysulfone (PSU) with sulfonic acid functionalized aliphatic dendrons and sulfonated comb-type PSU structures are developed and investigated in a comparative study as non-fluorinated proton exchange membrane (PEM) candidates. In each case the side chains are synthesized and introduced in their sulfonated form onto an azide-functiona

The initial stage of the Maillard reaction, protein lactosylation, occurs during heat treatment of milk and continues during subsequent storage. We compared the initial lactosylation as well as the rate of lactosylation of milk proteins during storage in UHT milk subjected to direct or indirect heat treatment using liquid chromatography (LC) coupled with electrospray injection mass spectrometry (E

In the present study, mesoscale simulations of grain growth in UO2 are performed using a 2D level set representation of the polycrystal grain boundary network, employed in a finite element setting. Anisotropic grain boundary properties are considered by evaluating how grain boundary energy and mobility varies with local grain boundary character. This is achieved by considering different formulatio

The European taxon Delia pruinosa (Zetterstedt) currently treated as one species is shown to represent a complex of several closely related species all characterized by the short antennnae, enlarged proboscis with strong, black prestomal teeth and a weak tibial setation. Biologically, all members of this Delia pruinosa species group may share the larval habit of living in seed capsules of various

Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3 fb(-1) of pp collisions produced by the Large Hadron Collider at a center-of-mass energy of root s = 8 TeV and recorded by the ATLAS detector. Cross sections are obtained from measured H -> gamma gamma and H -> ZZ*. 4l event yields, which are combined accounting for detector efficiencies, f

The articulating surfaces of 6 ultra-high molecular weight polyethylene cups were exposed to curing polymethyl methacrylate (PMMA) bone-cement and examined with scanning electron microscopy and laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). Three of the cups were exposed to blood and bone-cement, and the rest were exposed to bone-cement only. After removal of the bone-ceme
