The data was analyzed in a randomized complete block design (RCBD) in which the treatments were arranged in a 4 x 3 x 3 {high-amylose content (0, 20, 40 and 60%) x moisture content (20, 22, and 18 or 24%) x extruder screw speed (200, 300 and 400 rpm)} factorial arrangement of treatments with two replicants. The collected results indicate that the maximum amount of expansion occurs when the screw speed and moisture content are both decreased and the high-amylose corn starch content is increased. The puff density increased and the specific volume decreased when screw speed and starch content decreased and moisture content increased. While the original puff breaking strength and hardness were only affected by the moisture content, the puffs containing more high-amylose corn starch exhibited significantly higher breaking strengths at higher water activities. The extruder responded to increases in screw speed and starch content and a decrease in moisture content with increases in temperature and specific mechanical energy. The Gordon-Taylor equation was used to predict the effect of water plasticization on the high-amylose corn puffs.","PeriodicalId":285769,"journal":{"name":"Submitted by the University of Missouri--Columbia Graduate School","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114768531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It consists of a micro-PCR chamber, micropumps, and micro-heaters. Additional components of the device include gel electrophoresis microchannels and solid core waveguide fluorescence collectors. The intended analyzer is a micro-fluidic platform that is principally based on the three-step polymerase chain reaction (PCR) mechanism. Currently, all off chip control is executed using a labview code. The micro-pumps, PCR chamber and capillary electrophoresis system have been designed fabricated and tested. For fabrication of the device, a regime has been developed for bonding PDMS surfaces to a variety of substrates (silicon in the present case). We have successfully achieved a compression in the cycle time by a factor of ten in our on chip PCR reactor as compared to the conventional PCR system and also amplify samples with pico-gram concentration. Fluorescent studies indicate negligible non-specific binding to our chip which has been a major problem in earlier assays. A working electrophoretic capillary and new biphasic gel material with extremely low background and high signal to noise ratio have been developed. We have further achieved low voltage capillary electrophoresis by doping different gel materials with conducting nano-particles. We envision this assay as a highly sensitive field deployable analyzer tool.","PeriodicalId":285769,"journal":{"name":"Submitted by the University of Missouri--Columbia Graduate School","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127747484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first topic studied is about the relationship between speculation and the crude oil price and the related implications on the macroeconomic growth and inflation. We use a structural vector autoregression (VAR) model to decompose the shocks of the crude oil price and use the gold price as a proxy for the speculative information. Our results show that speculative information plays a very important role in driving crude oil price shocks; it accounts for about 20% of the variation of the oil price. Furthermore, we show that speculative shocks to the crude oil price are corrleted to future macroeconomic downturns. We also show that speculative shocks may create inflation pressure. The second topic is about the relationship between the oil price volatility and the US stock market. It includes two subtopics: i) the volatility spillovers between the crude oil market and the US stock market and ii) the relationship between oil price volatility and real stock returns on the US market. We use a generalized autoregressive conditional heteroskedasticity (GARCH) specification to model the volatility on both the oil and stock markets and then utilize an extension of the GARCH-M (GARCH in mean) vector autoregression (VAR) model to capture the volatility spillover relationship between the two markets and the relationship between the volatility of the oil price and stock returns at the same time. Further, we detect a structural change of the oil price-stock returns relationship near the middle of 1987. A unidirectional volatility spillover from the stock market to the oil market is found to be statistically significant before the break, while a negative relationship between oil price volatility and the conditional mean of stock returns is more pronounced afterwards.","PeriodicalId":285769,"journal":{"name":"Submitted by the University of Missouri--Columbia Graduate School","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126508576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of optimized agricultural productivity has long been fulfilled through manipulation of indigenous microbial communities for example by applying microbial inoculants. We hypothesized that application of SCD ProBio BalanceTM Plus (PBP), a particular consortia probiotic product, may enhance soil microbial diversity, thus improving pathogen control and amplifying crop residue turnover. To test the hypothesis, field experiment was established in Central Missouri on Mexico silt loam soils under two different management situations: (1) restored grassland; (2) standard corn/soybean rotation. During the 2012 growing season, soils were amended with the PBP product at the rate of 100L ha (treatment) or water (control). The treatment was replicated in triplicate and soils were sampled to the depth of 10cm and sampling was repeated eight times throughout the experiment. Soil microbial diversity was surveyed through 16srDNA DGGE. Furthermore, soil enzymatic activity was examined with respect to dehydrogenase activity and the capacity to digest fluorescein diacetate. Application of PBP correlated with no major changes in soil enzymatic activity or soil microbial diversity. Certain limitations may have obscured the actual impacts of","PeriodicalId":285769,"journal":{"name":"Submitted by the University of Missouri--Columbia Graduate School","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115840769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
