Extremal probability bounds in combinatorial optimization
No full textIn this paper, we compute the tightest possible bounds on the probability that the optimal value of a combinatorial optimization problem in maximization form with a random objective exceeds a given number, assuming only knowledge of the marginal distributions of the objective coefficient vector. The bounds are 'extremal' since they are valid across all joint distributions with the given marginals. We analyze the complexity of computing the bounds, assuming discrete marginals, and identify instances when the bounds are computable in polynomial time. For compact 0/1 V-polytopes, we show that the tightest upper bound is weakly NP-hard to compute by providing a pseudopolynomial time algorithm. On the other hand, the tightest lower bound is shown to be strongly NP-hard to compute for compact 0/1 V-polytopes by restricting our attention to Bernoulli random variables. For compact 0/1 H-polytopes, for the special case of PERT networks arising in project management, we show that the tightest upper bound is weakly NP-hard to compute by providing a pseudopolynomial time algorithm. The results in the paper complement existing results in the literature for computing the probability with independent random variables.</p
Effects of corn quality and storage on dry grind ethanol production
No full textCorn dry grind industry is the major contributor of ethanol production in the US. Ethanol plants incur economic losses due to seasonal variations in ethanol yields. Ethanol yields typically are low during the first month after harvest, increase for the next six to seven months and decrease again three to four months before next harvest. There is little published information on factors causing variation in dry grind ethanol concentrations. One possible cause associated with ethanol yield variability is incoming grain quality. The main objectives of this study were to quantify ethanol yield variation over time at a dry grind facility, evaluate relationships among corn quality attributes and ethanol yields and determine physiologic changes in corn protein quality during storage and its effects on ethanol yields.
Corn from a Midwestern ethanol plant (commodity corn) and an identity preserved corn hybrid from a seed company (control corn stored at 4° C) were used to study the effects of incoming corn on ethanol concentrations. Ethanol concentrations were determined every two weeks for one year using conventional dry grind procedure. Variations in ethanol concentrations were significant and variability patterns for commodity and control corn followed the same trend. Highest ethanol concentrations were seen in the month of January. Variation with control corn suggested that storage time is a significant factor affecting ethanol concentrations. Effects of different enzyme treatments on mean ethanol concentration over a year were evaluated. Two liquefaction enzymes (optimum pH – 5.8 and 5.1, respectively), two saccharification enzymes (optimum pH – 5.0) and one protease were used in five enzyme treatments (I, II, III, IV and V). Final ethanol concentration with enzyme treatment V was (17.5 ± 0.486)% v/v. This was 0.6% higher than enzyme treatment I resulting in an additional ethanol production of 600,000 gallons/year in a 100 million gallon/year ethanol plant. Using effective enzymes increases overall dry grind ethanol production and ethanol plant profitability.
Commodity corn samples were analyzed for physical quality parameters (test weight, kernel weight, true density, percent stress cracks and moisture content) and composition (starch, protein, oil and soluble sugars contents). There were variations in corn quality parameters and ethanol concentrations. Correlation coefficients were significant but low (-0.50< r < 0.50) between starch content and final ethanol concentrations (72 hr) and total soluble sugar content and ethanol concentrations at 72 and 48 hr. Ethanol concentrations (at 24, 48 and 72 hr) were predicted as a function of a combination of grain quality factors using multiple regression methods; however, the R2 values obtained were low. Ethanol concentration variations were not related to physical and chemical composition quality factors.
Physiologic changes in corn protein quality (soluble protein contents, initial free amino nitrogen (FAN) content and susceptibility to enzyme hydrolysis) during storage at refrigerated and ambient conditions were investigated. Albumin, prolamin, glutelin contents and initial FAN contents of corn slurry varied with storage time; however, there were no effects of storage temperatures (ranging from -7 to 23°C) on soluble protein and FAN contents. Albumin content decreased; whereas, prolamin content increased from wk 8 to 40. Susceptibility to enzyme hydrolysis was affected during storage; highest rate of protein hydrolysis was observed during wk 20. Variation in ethanol yields for corn stored at ambient and refrigerated conditions followed similar trends. Final ethanol yields (72 hr) had no correlations with protein quality attributes; however, ethanol yields at 24 hr correlated with glutelin (r = -0.76) and prolamin (r = +0.74) content.Submission original under an indefinite embargo labeled 'Open Access'.

Seasonal variation of radionuclides concentration in sand samples collected from Southern coastal areas of Kerala, India
No full textSouthern coastal parts of Kerala are well-reported high background radiation areas. Hence, the radiological protection of the population in this region may have some concern. In the present work, samples were collected during three different seasons, namely premonsoon, monsoon, and postmonsoon. The radionuclide activities obtained for various seasons have been compared in order to understand the enrichment of radionuclides during various seasons. The activities of natural radionuclides, namely 40K, 226Ra, and 232Th in sand samples collected from Southern coastal parts of Kerala were determined using NaI (Tl) gamma-ray spectrometer. Sand samples collected during postmonsoon showed enhanced level of radionuclides concentration. The radiation dose to the population was also estimated from the activities of radionuclides in order to assess the radiation levels. The calculated values of risk assessment parameters were within the safe limits, which indicate the radiation exposure to the population due to these radionuclides is insignificant. However, seasonal variation of radionuclides concentration is significant. The results of the present systematic investigation are presented and discussed here in detail

High-pressure Raman investigation of high index facets bounded alpha-Fe2O3 pseudocubic crystals
No full text[EN] High index facet bounded alpha-Fe2O3 pseudocubic crystals has gained the attention of the scientific community due to its promising electrochemical sensing response towards aqueous ammonia. The structural stability of alpha-Fe2O3 pseudocubic crystals is investigated through high-pressure Raman spectroscopy up to 22.2 GPa, and those results are compared with our ab initio theoretical calculations. The symmetry of the experimental Raman-active modes has been assigned by comparison with theoretical data. In addition to the Raman-active modes, two additional Raman features are also detected, whose intensity increases with compression. The origin of these two additional peaks addressed in this study, reveals a strong dependence on the geometry and the low dimensionality as the most plausible explanationNeravathu G Divya acknowledges DST FIST for FESEM analysis, Department of Physics, Cochin University of Science and Technology, Kerala, India.
