Hopper charging with spherical particles including rolling resistance mechanism - Case Study
Project Description Evaluate the feasibility of using the distinct‐ element modeling to study the flow and segregation of frictional particles without cohesion. Simulate an experimental test corresponding to the charge/discharge of a scale model batch hopper. Analyze the segregation observed in the hopper after its charge.

The effects of Picea schrenkiana forest litter on snow surface albedo
In this paper, we analyze the characteristics of the snow albedo of different underlying surfaces based on measurements of shortwave radiation and observations of forest litter on snow surfaces, both in an open, unforested environment and in areas with differing forest canopy openness. The fractional litter coverage was obtained through the binarization of digital photos of forest litter ...

Firm size and its impact on continuous improvement
Building on a volume of previous work on continuous improvement (CI) in the supply chain based on the continuous improvement in manufacturing activity (CIMA) model, this paper extends earlier work by examining the influences of firm size CI. Findings of this study provide support for earlier studies, which held that firm size generally has little influence on CI innovation activity. However, ...

Multi-residue mycotoxin analysis of dry distillers grains
Distillers grains (DG) are the still residues after the ethanol has been collected. Approximately 90% of US production is used in domestic animal feed. Any Mycotoxins present in the fresh corn can be concentrated by a factor of three. Contamination can also occur during storage. This raises concern about the potential animal and human health hazards from the use of Mycotoxincontaminated ...

Corn response to competition: growth alteration vs. yield limiting factors
Competition mechanisms among adjacent plants are not well understood. This study compared corn growth and yield responses to water, N, and shade at 74,500 plants ha–1 (1x) with responses to water and N when planted at 149,000 plant ha–1. Plant biomass, leaf area, chlorophyll content, reflectance, and enzyme expression (transcriptome analysis) were measured at V-12. Grain and stover yields were ...

Japanese sake-brewing rice cultivars show high levels of globulin-like protein and a chloroplast stromal HSP70
White-core is an important trait in the selection of rice (Oryza sativa L. ssp. japonica) for sake (Japanese rice wine) production. The present study was conducted to find differences between the endosperm protein pattern of white-core–bearing sake-brewing cultivars and those of normal rice grains. Protein patterns of white-core sake-brewing grains were compared with those of normal cultivars by ...

A comparison of mixed-model analyses of the Iowa Crop performance test for corn
Multienvironment trials generally have highly unbalanced data structures in which a particular cultivar is only observed in a subset of all environments for which data are available. A very common approach to reporting data from such unbalanced data is to subset the data into balanced subsets and restrict comparisons within balanced subsets. Such an approach results in much information being ...

Confirmation of molecular markers and agronomic traits associated with seed phytate content in two soybean RIL populations
The concentration of phytate is an important consideration when analyzing feed grain for livestock. Simple sequence repeat markers Satt237 and Satt561 were found to be linked to quantitative trait loci (QTLs) for phytate concentration in soybean [Glycine max (L.) Merr.] seed. Previous research also established a significant correlation between seed inorganic phosphorus (Pi) and seed phytate. The ...

Grain sorghum and corn comparisons: yield, economic, and environmental responses
Grain sorghum [Sorghum bicolor (L.) Moench] is often grown where water stress is expected. But, improved drought tolerance in corn (Zea mays L.) hybrids has resulted in increased dryland corn production in preference to grain sorghum. However, grain sorghum may still have a yield advantage over corn in drought prone environments. This study was conducted to determine if grain sorghum has either a ...

Adaptation of cool-season grain legume species across climatically-contrasting environments of Southern Europe
Information on most-adapted species is required to increase the economic sustainability and the utilization of cool-season feed legumes in southern Europe. This study aimed to compare pea (Pisum sativum L.), faba bean (Vicia faba L.), narrow-leafed lupin (Lupinus angustifolius L.), and white lupin (L. albus L.) across Italian environments which contrasted for geoclimatic area (subcontinental or ...

Measuring grain protein concentration with in-line near infrared reflectance spectroscopy
The advent of near infrared (NIR) on-combine sensors gives growers the opportunity to measure the grain protein concentration of wheat (Triticum aestivum L.) during harvest. A study consisting of three sequential experiments (laboratory bench, combine test stand, and field) was conducted to evaluate the performance of an in-line, NIR reflectance spectrometer, referred to as the ProSpectra Grain ...

Determination of Clay Size Fraction of Marine Clays
This technical note describes a study on the effect of different dispersing agents and the quantity of same on the grain-size distribution and in particular the percentage of clay size. The results confirm that the existing practice of using 100 mL of standard dispersing agent, viz. sodium hexametaphosphate and sodium carbonate solution, is suitable for marine clays also. The clay size fraction ...
