The aim of the present study was to compare Fe absorption from industrially-manufactured and home-cooked cereal foods. Fe absorption was measured using the radiolabelled Fe extrinsic tag technique in thirty-nine adult human subjects from cereal porridges manufactured by extrusion cooking or roller-drying, and from the same cereal flours after home cooking to produce pancakes, chappattis or brea...

In this paper we describe the version of the planner ROLLER submitted to the learning track of the International Planning Competition. This version, learns domain dependent general policies with the aim of improving a lookahead strategy for forward search planning. ROLLER performs the policy learning in a two-step classification process with the relational classifier TILDE. At the first step th...

Large scale laboratory experiments concerning breaking wave propagation over a fixed-bed, barred beach were performed. The primary observations of interest were video intensity time series obtained from a set of high-resolution video cameras in order to study the onset of wave breaking in shallow water and wave roller transformation in the surf zone. The approach is new in the sense that the an...

Obtaining finely ground, homogeneous plant and soil samples for chemical analysis without cross contamination is a major concern when using direct combustion procedures for determination of total nitrogen (N), total carbon (C), and isotope-ratio analysis. A rollermilling device, using square glass bottles instead of round grinding bottles, was evaluated. Rotation of the square bottles on the ro...

OBJECTIVE Among the equipments used in cardiopulmonary bypass the roller pumps have great importance with various models available from several manufacturers. The calibration is an important factor in hemolysis rates and its potential is different in each. Researchers do not always approach details on the pump bed profiles assuming that the standardized calibration settings ensure equal and com...

Although many precision fabrication techniques have demonstrated the ability to produce microstructures and micro-devices with sub 100 nm accuracy, we are yet to see a scalable manufacturing process for large-area production. One promising solution to scalable microand nanofabrication is thermal roller imprinting. However, existing investigations on thermal roller imprinting revealed poor patte...

Six hull-less barley cultivars widely grown in China were roller-milled to produce bran, shorts and flour fractions. The distribution and molecular characteristics of β-glucans from the three roller-milled fractions were investigated. The β-glucan contents in the six hull-less barley cultivars varied from 4.96% to 7.62%. For all the six cultivars, the shorts fraction contained the highest conce...

in this study, the effect of furrow firming rollers were investigated to improve furrow irrigation parameters such as: advance time, runoff, deep percolation and irrigation efficiency (application efficiency) in the roller treatments, nonroller treatments (traditional) and treatment of including compacted with tractor wheel in the miandab agriculctural station in west azerbaijan during 2001-200...

Centrifugal pumps are superior to roller pumps for extended support durations in terms of pump-induced haemolysis. In this study, we evaluated the commonly used Biomedicus BP 50 and compared it with the Jostra Rotaflow and a standard roller pump in an in vitro test circuit. Each circuit was run for a six-day period and repeated five times. Plasma haemoglobin values showed the roller pump to bec...
