A rotating cylindrical electrode apparatus, which provided cylindrical Couette flow, was used to simulate flow electrification in an electric power transformer. The apparatus had Shell Diala A transformer oil filling the annulus between coaxial cylindrical stainless steel electrodes that were either bare metal, or covered by a thin copper sheet and/or EHV-Weidmann HiVal pressboard insulation. E...

The study examined the effect of moisture content on maize shelling speed using a manually operated hand Sheller (cone type). Twenty (20) unthreshed maize cob samples (A-J) were used for the study. The samples were analysed in the laboratory for parameters such as weight of samples before and after drying, moisture content and shelling speed. The result indicated that sample J, after sixty nine...

the presented study shows a simple way for optimization of extrusion process, which was used for deterioration of cyanogenic glycosides – antinutritive components of linseed, with minimum damage of essential alpha-linolenic acid (ala) at the same time. extrusion of the material was done on a laboratory single screw extruder. content of hydrogen cyanide (hcn) as a measurement of cyanogenic glyco...

In order to determine the energy needed to artificially dry a product, the latent heat of vaporization of moisture in the product, hfg, must be known. Generally, the expressions for hfg reported in the literature are of the form hfg = h(T)f(M), where h(T) is the latent heat of vaporization of free water, and f(M) is a function of the equilibrium moisture content, M. But expressions of this type...

This thesis focuses on two main areas: methods for assessing regional supply potentials of reed canary grass (Phalaris arundinacea L.) (RCG); and process technology for the production of high-quality RCG pellets. Partial equilibrium modelling, incorporating a break-even price approach, was used to examine supply potentials for RCG in Västerbotten County, northern Sweden. A remote sensing method...

In most studies, moisture sorption into amorphous foods is expressed as a change in the bulk moisture content, which does not provide detail on how a moisture front moves into the food. This study was targeted towards characterization of the moisture behavior in amorphous saccharide materials of different molecular weight (MW), glass transition temperature (Tg) and moisture content. Various sug...

The biogeographical distribution of soil bacterial communities has been widely investigated. However, there has been little study of the biogeography of soil archaeal communities on a regional scale. Here, using high-throughput sequencing, we characterized the archaeal communities of 94 soil samples across the eastern Tibetan Plateau. Thaumarchaeota was the predominant archael phylum in all the...

An NMR imaging technique published in literature was adapted to investigate the role of glass transition on Fickian and non-Fickian modes of moisture transport in pasta. The modified technique allowed measuring the moisture distribution in samples with initial moisture content from 10% to 50% or higher. A change in slope in the signal intensity versus moisture content curves indicated different...
