    Mind The Gap: And 2 Other Mysteries

    Get PDF
    Mind the Gap, a novel, concerns a murder that occurs in London in 2001. Eight students from a university, accompanied by two faculty members, take a theatrical tour of London and Stratford, during which they see and discuss twelve plays. But their tour is ruined when one member of the group is murdered. The two other mysteries in Mind the Gap and 2 Other Mysteries, The Value of Books and Midtown Detectives, are relatively brief -- longer than short stories, but decidedly shorter than novels. They both present intriguing tales of suspense, and both are written in styles that contrast markedly with the style of Mind the Gap.

    Development of a lab-scale auger reactor for biomass fast pyrolysis and process optimization using response surface methodology

    A lab-scale biomass fast pyrolysis system was designed and constructed based on an auger reactor concept. The design features two intermeshing augers that mix biomass with a heated bulk solid material that serves as a heat transfer medium. A literature review, engineering design process, and shake-down testing procedure was included as part of the system development. A response surface methodology was carried out by performing 30 experiments based on a four factor, five level central composite design to evaluate and optimize the system. The factors investigated were: (1) heat carrier inlet temperature, (2) heat carrier mass feed rate, (3) rotational speed of the reactor augers, and (4) volumetric flow rate of nitrogen used as a carrier gas. Red oak (Quercus Rubra L.) was used as the biomass feedstock, and S-280 cast steel shot was used as a heat carrier. Gravimetric methods were used to determine the mass yields of the fast pyrolysis products. Linear regression methods were used to develop statistically significant quadratic models to estimate and investigate the bio-oil and biochar yield. The optimal conditions that were found to maximize bio-oil yield and minimize biochar yield are high nitrogen flow rates (3.5 sL/min), high heat carrier temperatures (625yC), high auger speeds (63 RPM) and high heat carrier feed rates (18 kg/hr). The produced bio-oil, biochar and gas samples were subjected to multiple analytical tests to characterize the physical properties and chemical composition. These included determination of bio-oil moisture content, solid particulate matter, water insoluble content, higher heating value, viscosity, total acid number, proximate and ultimate analyses and GC/MS characterization. Statistically significant linear regression models were developed to predict the yield of gaseous carbon monoxide, the hydrogen content, moisture content and water-insoluble content of the bio-oil, and the vapor reaction temperature at the reactor outlet. A significant result is that with increasing bio-oil yield, the oxygen to carbon ratio and the hydrogen to carbon ratio of the wet bio-oil both decrease, largely due to a reduction in water content. The auger type reactor is currently less researched than other systems, and the results from this study suggest the design is well suited for fast pyrolysis processing. The reactor as designed and operated is able to achieve high liquid yields (greater than 70%-wt.), and produces bio-oil and biochar products that are physically and chemically similar to products from other fast pyrolysis reactors

    The Polarizing Effect of Arousal on Negotiation

    Get PDF
    In this research, we examined the impact of physiological arousal on negotiation outcomes. Conventional wisdom and the prescriptive literature suggest that arousal should be minimized given its negative effect on negotiations, whereas prior research on misattribution of arousal suggests that arousal might polarize outcomes, either negatively or positively. In two experiments, we manipulated arousal and measured its effect on subjective and objective negotiation outcomes. Our results support the polarization effect. When participants had negative prior attitudes toward negotiation, arousal had a detrimental effect on outcomes, whereas when participants had positive prior attitudes toward negotiation, arousal had a beneficial effect on outcomes. These effects occurred because of the construal of arousal as negative or positive affect, respectively. Our findings have important implications not only for negotiation, but also for research on misattribution of arousal, which previously has focused on the target of evaluation, in contrast to the current research, which focused on the critical role of the perceiver
