OBJECTIVE To evaluate the impact of the fortification of rolls with microencapsulated iron sulfate with sodium alginate on the hemoglobin levels in preschoolers as compared to controls. METHODS Double-blind randomized controlled trial comprised of children aged 2 to 6 years with initial hemoglobin exceeding 9 g/dL from four not-for-profit daycares randomly selected in the city of São Paulo - ...

Fish rolls are a popular value-added, fish based, ready-to-eat food snack sold in Lagos, South west Nigeria. The study was carried out to determine nutritional composition of commercially fish rolls available in some parts of Lagos metropolis. Six brands of fish rolls were collected and analyzed for proximate composition and energy values with a view to evaluate their levels of nutrients. The n...

Operation monitoring of paper machinery is financially essential due to improved quality of the end product and increased machine lifetime. Rotating cylinders in rolling contact are essential parts when manipulating paper web. Roll stability is becoming more and more important since the paper machine speeds are still increasing. Dynamical instability of rolls leads to contact vibrations in roll...

The concept of communication media repertoires introduced by Watson-Manheim and Bélanger (2007) has extended the existing literature by adding a technology-in-practice perspective to the examination of communication media choice in an organizational setting. While Watson-Manheim and Bélanger (2007) have focused on describing the existing media repertoires (set of available media and existing us...

A conventional twin-roll caster usually casts strips at a speed slower than 2 m/min and roll load greater kN/mm. vertical-type high-speed can cast aluminum alloy higher 10 smaller 550 N/mm due to the effect of large thermal conductivity copper rolls, compared with that steel rolls. However, properties an strip 140 30 are not clear. In this study, Al–5%Mg were loads 88 using caster. The effects ...

Reshaping process is a widely used method for producing tubes with non-circular cross sections. Owing to the friction between pipe and rolls, initial round pipe moves forward and consequently, it gradually formed into square or rectangular one. In practice, geometric profile of the rolls will be changed after a while. These changes would be detrimental the production of faultless products. Ther...
