BACKGROUND: Obesity has been increasing in both developed and developing countries. One of the prevention strategies is controlling energy intake. The objective of this research was to examine the effects of four designed whole grain products, i.e. WG 100, WG 50/50, WG 50/50 + RS and KWWB, on colonic fermentation and appetite variables in healthy subjects. METHODS: The determination of dietary fib
With the projected increase in the number of hydrogen-fueled trucks, it can beexpected that it will become more common for such vehicles to be involved in road collisions. Even if hydrogen vehicles are designed with a quick-closing valve on tanks in accordance with UN/ECE R134, a small volume of hydrogen will be contained downstream of this valve and in the fuel-cell recirculation system and thereWith the projected increase in the number of hydrogen-fueled trucks, it can be expected that it will become more common for such vehicles to be involved in road collisions.

It has been concluded by geologists that a significant amount of hydrogen is stored as point defects in nominally anhydrous minerals. Determination of the amount of hydrogen bound in these minerals is a step towards determining the total water content of the earth mantle as well as comprehending its internal water cycle. The possibility to measure hydrogen in thin geological samples by elastic p-p
One way to extend the lean-burn limit of a natural gas engine is by addition of hydrogen to the primary fuel. This paper presents measurements made on a one-cylinder, 1.6- liter natural gas engine. Two combustion chambers, one slow and one fast burning, were tested with various amounts of hydrogen (0, 5, 10 and 15%-vol) added to natural gas. Three operating points were investigated for each combus
Knowledge of hydrogen bonds is important in a wide range of scientific fields. However, information on the electronic state of hydrogen bonded molecules in liquids and solutions is still limited. We applied X-ray emission and absorption spectroscopy to observe the electronic state around oxygen of water and investigate the solvent dependence of occupied and unoccupied valence electronic states of

The thermodynamics and kinetics of formation of host-guest complexes between a series of bolaform surfactants of type C(n)Me(6)(2+)2Br(-) (n = 8, 10, and 12) and alpha-cyclodextrin and beta-cyclodextrin were studied with the aid of isothermal titration calorimetry (ITC) at 298.15 and 308.20 K. The association constant, the enthalpy, and the entropy of formation were determined. The obtained thermo
Of the many ways hydrogen can be produced, this chapter focuses on biological hydrogen production 12 by thermophilic bacteria and archaea in dark fermentations. The thermophiles are held as promising candidates 13 for a cost-effective fermentation process, because of their relatively high yields and broad substrate palette. Yet 14 many challenges remain to be faced, including improving productivit
DLE (Dry Low Emission) techniques are widely used today to reduce the harmful NOx emissions associated with high combustion temperatures. In many DLE systems the fuel and air are premixed which effectively keep the flame temperature as low as possible, ideally equal to the turbine inlet temperature. By using premixing stability issues such as flash back and combustion driven dynamics may occur. Op
The demand for fast and energy efficient (opto-)electronic applications needs high mobility semiconductor materials, such as InAs with a very high electron mobility and GaSb with a very high hole mobility. Beyond the material itself, also an innovative device geometry is needed, for example, the gate-all-around geometry that provides higher efficiency and electrostatic control for computational un
An economical and optimal construction of rainwater storage cistern in the Loess Plateau of Gansu is introduced. The collection alternatives of rainwater showed a dramatic difference on cistern water quality. Roof-yard catchment systems can harvest drinking water that generally meets the international guidelines. Among the tested disinfectants - chlorine dioxide, potassium permanganate, chloramine
Methanol steam reforming (MSR) is considered as an effective way to provide on-board hydrogen production technology for fuel cell applications. CuFe1.2Al.8O4 spinel catalyst was synthesized by sol–gel method and the chemical and physical properties were studied in-depth. X-ray diffraction, hydrogen-temperature programmed reduction (H2-TPR), BET, and scanning electron microscopy were used to charac

The European Commission wants to implement a single market for gas. One of the components of this market is a regulated provision for "security of supply" which consists of rules for the implementation and use of a given reserve stock of gas. We investigate the impact of this policy on the profitability of a storage operator, using data from Denmark and Italy. Keeping storage capacity constant, th
Various transport phenomena in conjunction with chemical reactions are strongly affected by reformer configurations and properties of involved porous catalyst layers. The considered composite duct is relevant for a methane steam reformer and consists of a porous layer for the catalytic chemical reactions, the fuel gas flow duct and solid plate. In this paper, a fully three-dimensional calculation
When working with district heating production, you often encounter problems with unbalanced energy consumption from the consumers during the 24 hours of a day. High energy consumption when it is morning and evening whiles it is low energy consumption on midday and during the night. This leads to higher wear and tear and an uneven production rate at the boilers. To solve this problem you can instal
Light kaonic atoms studies provide the unique opportunity to perform experiments equivalent to scattering at threshold, being their atomic binding energies in the keV range. High precision atomic X-rays spectroscopy ensures that the energy shift and broadening of the lowest-lying states of the kaonic atoms, induced by the strong interaction between the kaon and nucleus, can be detected. Kaonic hyd
The biothiols sensing mechanism of (E)-7-(diethylamino)-3-(2-nitrovinyl)-2H-chromen-2-one (DCO) has been investigated using the density functional theory (DFT) and time-dependent DFT methods. The theoretical results indicate that the excited-state intermolecular hydrogen bonding (H-B) plays an important role for the biothiols sensing mechanism of the fluorescence sensor DCO. Multiple H-B interacti
