Eureka College is a liberal arts college in Eureka, Illinois, related by covenant to the Christian Church . It has a strong focus on the mutual development of intellect and character. Stated core values are learning, service and leadership. Eureka offers a classical liberal arts education with an array of requirements that are designed to create well-rounded, critical thinking leaders. Popular majors include education, business, history, political science, communication, and the fine and performing arts. Enrollment in 2010–11 was about 785 students. Since 2005, the president of Eureka College has been J. David Arnold.Eureka College was the third college in the United States to admit men and women on an equal basis. Future U.S. president Abraham Lincoln spoke on campus in 1856. Future U.S. president Ronald Reagan graduated from Eureka College in 1932 with a degree in economics and sociology, and the college has continued to be closely associated with his legacy. In 2010, Eureka College was designated as a national historic district by the National Park Service. Wikipedia.

In Humboldt County, California, nest exclosures were used between 2001 and 2006 to reduce the predation of eggs aiding in the recovery of a threatened population segment of western snowy plovers (Charadrius nivosus). Due to a sudden increase in adult mortality in 2006, field biologists abandoned the use of nest exclosures. This paper describes a discrete-time stochastic model designed to compare two different management strategies (with and without exclosures) to predict the change in the plover population. The model uses beta distributions to model demographic parameters, and whenever possible, these distributions were fit to survey data of these populations. The model shows nest exclosures to be effective in increasing chick fledging rates. However, the model also shows that an increase in adult mortality potentially caused by the nest exclosures would counteract this increase in fledging rates. The model predicts that there will be a net negative effect on the population if these exclosures reduce adult survival to 90% of its unexclosed rate. The model also demonstrates that the population is dependent on immigration. © 2012 Wiley Periodicals, Inc. Source

The synthesis of two groups of aminochloropyrimidine bis-intercalators with different lipophilicity or limited flexibility of linkers as potential DNA intercalators is described. The lipophilic linkers in the synthesized bis-intercalators are represented by alternating methylene groups and oxygen atoms in a chain, with a pyrimidine ring containing an amino group and a chloro group at each end (10, 11, 12, 13). The bis-intercalators with limited flexibility contain chains with two benzene rings (15, 16, 17, 18, 19). All these compounds were obtained by nucleophilic substitution of 2-amino-4,6-dichloropyrimidine (1). The spectral data and other physical properties of the new compounds are presented. The anticancer activity of these newly synthesized compounds is also reported. Compounds 7 and 8 described in one of our previous publications display good anticancer activity against murine lymphoma. © 2014 HeteroCorporation. Source

The yeast Kluyveromyces marxianus is a potential microbial catalyst for fuel ethanol production from a wide range of biomass substrates. To improve its growth and ethanol yield at elevated temperature under microaerophilic conditions, K. marxianus NRRL Y-1109 was irradiated with UV-C using automated protocols on a robotic platform for picking and spreading irradiated cultures and for processing the resulting plates. The plates were incubated under anaerobic conditions on xylose or glucose for 5 mo at 46 °C. Two K. marxianus mutant strains (designated 7-1 and 8-1) survived and were isolated from the glucose plates. Both mutant strains, but not wild type, grew aerobically on glucose at 47 °C. All strains grew anaerobically at 46 °C on glucose, galactose, galacturonic acid, and pectin; however, only 7-1 grew anaerobically on xylose at 46 °C. Saccharomyces cerevisiae NRRL Y-2403 did not grow at 46 °C on any of these substrates. With glucose as a carbon source, ethanol yield after 3 d at 46 °C was higher for 8-1 than for wild type (0.51 and 0.43 g ethanol/g glucose, respectively). With galacturonic acid as a carbon source, the ethanol yield after 7 d at 46 °C was higher for 7-1 than for wild type (0.48 and 0.34 g ethanol/g galacturonic acid, respectively). These mutant strains have potential application in fuel ethanol production at elevated temperature from sugar constituents of starch, sucrose, pectin, and cellulosic biomass. © 2013 Society for Laboratory Automation and Screening.
