Reflections on the American Lyceum: The Legacy of Josiah Holbrook and the Transcendental Sessions Undergraduate
(2014-10-02)
The American Lyceum Movement became a pivotal foundation of U.S. adult education during the nineteenth-century. Holbrook recognized adult learners’ educational demands diversified during the rise of industrialism. Thus, ...
Microbial Electricity Generation Enhances Decabromodiphenyl Ether (BDE-209) Degradation
(PLos One, 2013-08-05)
Due to environmental persistence and biotoxicity of polybrominated diphenyl ethers (PBDEs), it is urgent to develop potential technologies to remediate PBDEs. Introducing electrodes for microbial electricity generation to ...
Exposure of Soil Microbial Communities to Chromium and Arsenic Alters Their Diversity and Structure
(PLos One, 2012-06-29)
Extensive use of chromium (Cr) and arsenic (As) based preservatives from the leather tanning industry in Pakistan has had a deleterious effect on the soils surrounding production facilities. Bacteria have been shown to be ...
Crumple: A Method for Complete Enumeration of All Possible Pseudoknot-Free RNA Secondary Structures
(PLos One, 2012-12-27)
The diverse landscape of RNA conformational space includes many canyons and crevices that are distant from the lowest minimum free energy valley and remain unexplored by traditional RNA structure prediction methods. A ...
Emissions of NO and NH3 from a Typical Vegetable-Land Soil after the Application of Chemical N Fertilizers in the Pearl River Delta
(PLos One, 2013-03-19)
Cropland soil is an important source of atmospheric nitric oxide (NO) and ammonia (NH3). Chinese croplands are characterized by intensive management, but limited information is available with regard to NO emissions from ...
Transient Growth Arrest in Escherichia coli Induced by Chromosome Condensation
(PLos One, 2013-12-23)
MukB is a bacterial SMC (structural maintenance of chromosome) protein that regulates the global folding of the Escherichia coli chromosome by bringing distant DNA segments together. We report that moderate overproduction ...
Similar Gene Estimates from Circular and Linear Standards in Quantitative PCR Analyses Using the Prokaryotic 16S rRNA Gene as a Model
(PLos One, 2012-12-19)
Quantitative PCR (qPCR) is one of the most widely used tools for quantifying absolute numbers of microbial gene copies in test samples. A recent publication showed that circular plasmid DNA standards grossly overestimated ...
Prefrontal Control of the Amygdala during Real-Time fMRI Neurofeedback Training of Emotion Regulation
(PLos One, 2013-11-06)
We observed in a previous study (PLoS ONE 6:e24522) that the self-regulation of amygdala activity via real-time fMRI neurofeedback (rtfMRI-nf) with positive emotion induction was associated, in healthy participants, with ...
Optimizing Wettability to Maximize Production from Retrograde Condensate Reservoirs - A Simulation Approach
(2017-05-12)
It is well documented that significant production loss can be expected when regions of a retrograde condensate reservoir fall below the dew point, leading to liquid banking around the wellbore. Several methods have been ...
Fruit and Soil Quality of Organic and Conventional Strawberry Agroecosystems
(PLos One, 2010-09-01)
BackgroundSale of organic foods is one of the fastest growing market segments within the global food industry. People often buy organic food because they believe organic farms produce more nutritious and better tasting ...
