Modeling Distillers Dried Grains with Solubles (DDGS) Mass Flow Rate as Affected by Drying and Storage Conditions

Ethanol production in 2015 was over 15 million gallons in the United States, and it is projected to increase in the next few years to meet market demands. With the continued growth in the ethanol industry, there has been enormous expansion in distillers grains production. Because the local market for distillers dried grains with solubles (DDGS) is often saturated, it is essential to transport DDGS long distances, across the United States and to international markets. Caking and agglomeration of DDGS particles in hoppers and other storage structures are typical during transportation. The current study deals with DDGS prepared by combining condensed distillers solubles (CDS) with distillers wet grains and then drying at varying temperatures. DDGS was stored in conical hoppers under varying ambient temperature, consolidation pressure, and time conditions. We investigated the effects of CDS (10, 15, and 20% wb), drying temperature (100, 200, and 300°C), drying time (20, 40, and 60 min), cooling temperature (0, 25, and 50°C), consolidation pressure (0, 1.72, and 3.43 kPa), and consolidation time (0, 3, and 6 days) levels on various flow parameters. To examine these factors, Taguchi’s experimental design with an L18 orthogonal array was implemented. Response surface modeling yielded mass flow rate = f(Hausner ratio, angle of repose) with R2 = 0.99, and it predicted moisture content for good, fair, and poor flow. Results showed that drying temperature, drying time, and cooling type were the main factors in predicting mass flow rate. The Johansson model for predicted mass flow rate was calibrated with experimental data, and a new parameter, compressibility factor, with a value of 0.96 g2/(min cm3), was determined to quantify the divergence of compressible and cohesive materials (such as DDGS) for free-flowing bulk solids. Thus, the predicted models may be beneficial for quantitative understanding of DDGS flow

An Introduction to Statistical Issues and Methods in Metrology for Physical Science and Engineering

This article provides an overview of the interplay between statistics and measurement. Measurement quality affects inference from data collected and analyzed using statistical methods while appropriate data analysis quantifies the quality of measurements. This article brings material on statistics and measurement together in one place as a resource for practitioners. Both frequentist and Bayesian methods are discussed

Cytogenetics of human malignant melanoma

There has been a tremendous recent resurgence of interest in examining chromosomal abnormalities in human cancers (particularly solid tumors). This interest has been stimulated by the molecular examination of recurring chromosome abnormalities, and the recognition that they may pinpoint the location of growth regulatory sequences (e.g. cellular oncogenes). This finding coupled with the clear recognition that specific chromosome abnormalities can also have important diagnostic and prognostic implications, have caused this avenue of research to expand at a significant rate. The following brief review will summarize the current state of knowledge regarding recurring chromosome abnormalities in human malignant melanoma. A discussion of chromosome changes in pre-malignant skin lesions, primary melanoma, and metastatic melanoma is described. Brief descriptions of the potential clinical utility, and biologic relevance of chromosome abnormalities in this disorder are also discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44500/1/10555_2004_Article_BF00049408.pd

Auditory functions in raised intracranial pressure

A study of auditory functions was made in 25 cases of raised intracranial tension. It was noted that an average loss of 30 dB could occur due to raised intracranial pressure and that this improves after the return of normal pressure in the cranium, as seen in 16 cases submitted to surgery. Audiometric examination has been found to be a valuable diagnostic investigation in cases of raised intracranial tension. Whilst dealing with rather advanced cases of intracranial space-occupying lesions our neurosurgical colleagues were struck by a high incidence of symptoms referable to VIII nerve even when the cause or raised intracranial pressure was away from this nerve. We, therefore, instituted a collaborative study of the effects of raised intracranial pressure on cochlear and vestibular functions. During the last year we have studied 60 patients but for the purpose of this report we have selected first 25 cases to illustrate that the clinical impression finds significant confirmation from otoneuro-logical investigations. The auditory function tests revealed a significant impairment, although routine tests for vestibular functions (caloric test, rotation test, Fukuda's writing test and Fukuda's stepping test) were not much altered. This report, therefore, is restricted to the study of auditory functions only
