Economic Impacts of Climate Change Mitigation in the State of Montana
In 2017, several sources of the state of Montana’s economy are susceptible to climate change impacts; those industries include tourism, agriculture, wildlife management, and outdoor recreation. In recent years, political figures, national governments, and grassroots organizations have called for extreme methods of climate change mitigation for the entire global community. In response, communities, countries, and individuals have responded and changed their habits and policies to begin mitigating climate change.
During this research, I analyzed peer reviewed articles, government documents, and interviews from Montana economy experts. From those results, I was able to discern the approximate amount of money associated with the Montana industries that are at risk from climate change. This dollar amount was compared to the estimated profit from industries associated with fossil fuels, or those industries that would succeed if no climate change mitigation was addressed.
In addition, my research included using climate model research to establish how the global impact of greenhouse gases would impact at-risk Montana industries. After synthesizing the results from the climate models with the comparative dollar amounts of Montana industries, this research concludes Montana mitigation would negatively impact the Montana economy.
By means of secondary research and a synthesizing of the conclusions of credible economists, local energy experts, technology scientists, and climate scientists, this paper hypothesizes that extreme climate change mitigation methods in Montana would have no direct impact impact on the quality of Montana’s environment, and would actually decrease the total economic profit of the state of Montana and its collective inhabitants
Emulsion formation and stabilization by biomolecules: the leading role of cellulose
Emulsion stabilization by native cellulose has been mainly hampered because of its insolubility in water. Chemical modification is normally needed to obtain water-soluble cellulose derivatives. These modified celluloses have been widely used for a range of applications by the food, cosmetic, pharmaceutic, paint and construction industries. In most cases, the modified celluloses are used as rheology modifiers (thickeners) or as emulsifying agents. In the last decade, the structural features of cellulose have been revisited, with particular focus on its structural anisotropy (amphiphilicity) and the molecular interactions leading to its resistance to dissolution. The amphiphilic behavior of native cellulose is evidenced by its capacity to adsorb at the interface between oil and aqueous solvent solutions, thus being capable of stabilizing emulsions. In this overview, the fundamentals of emulsion formation and stabilization by biomolecules are briefly revisited before different aspects around the emerging role of cellulose as emulsion stabilizer are addressed in detail. Particular focus is given to systems stabilized by native cellulose, either molecularly-dissolved or not (Pickering-like effect).Financially support by the Portuguese Foundation for Science and Technology, FCT, via the projects PTDC/AGR-TEC/4814/2014, PTDC/ASP-SIL/30619/2017 and researcher grant IF/01005/2014.

Novel self-assembled morphologies from isotropic interactions
We present results from particle simulations with isotropic medium range
interactions in two dimensions. At low temperature novel types of aggregated
structures appear. We show that these structures can be explained by
spontaneous symmetry breaking in analytic solutions to an adaptation of the
spherical spin model. We predict the critical particle number where the
symmetry breaking occurs and show that the resulting phase diagram agrees well
with results from particle simulations.Comment: 4 pages, 4 figure
Observation of a Free-Shercliff-Layer Instability in Cylindrical Geometry
We report on observations of a free-Shercliff-layer instability in a
Taylor-Couette experiment using a liquid metal over a wide range of Reynolds
numbers, . The free Shercliff layer is formed by imposing a
sufficiently strong axial magnetic field across a pair of differentially
rotating axial endcap rings. This layer is destabilized by a hydrodynamic
Kelvin-Helmholtz-type instability, characterized by velocity fluctuations in
the plane. The instability appears with an Elsasser number above
unity, and saturates with an azimuthal mode number which increases with the
Elsasser number. Measurements of the structure agree well with 2D global linear
mode analyses and 3D global nonlinear simulations. These observations have
implications for a range of rotating MHD systems in which similar shear layers
may be produced.Comment: 5 pages, 4 figure
Snagger: A user-friendly program for incorporating additional information for tagSNP selection
<p>Abstract</p> <p>Background</p> <p>There has been considerable effort focused on developing efficient programs for tagging single-nucleotide polymorphisms (SNPs). Many of these programs do not account for potential reduced genomic coverage resulting from genotyping failures nor do they preferentially select SNPs based on functionality, which may be more likely to be biologically important.</p> <p>Results</p> <p>We have developed a user-friendly and efficient software program, Snagger, as an extension to the existing open-source software, Haploview, which uses pairwise <it>r</it><sup>2 </sup>linkage disequilibrium between single nucleotide polymorphisms (SNPs) to select tagSNPs. Snagger distinguishes itself from existing SNP selection algorithms, including Tagger, by providing user options that allow for: (1) prioritization of tagSNPs based on certain characteristics, including platform-specific design scores, functionality (i.e., coding status), and chromosomal position, (2) efficient selection of SNPs across multiple populations, (3) selection of tagSNPs outside defined genomic regions to improve coverage and genotyping success, and (4) picking of surrogate tagSNPs that serve as backups for tagSNPs whose failure would result in a significant loss of data. Using HapMap genotype data from ten ENCODE regions and design scores for the Illumina platform, we show similar coverage and design score distribution and fewer total tagSNPs selected by Snagger compared to the web server Tagger.</p> <p>Conclusion</p> <p>Snagger improves upon current available tagSNP software packages by providing a means for researchers to select tagSNPs that reliably capture genetic variation across multiple populations while accounting for significant genotyping failure risk and prioritizing on SNP-specific characteristics.</p
Siliceous microfossil succession in the recent history of two basins in Lake Baikal, Siberia
As part of the international cooperative Baikal Drilling Project, siliceous microfossil assemblage succession was analyzed in two short (∼ 30-cm) sediment cores from Lake Baikal. One core was recovered from the north basin (Core 324, 55°15′N, 109°30′E), a second from between the central and southern basins (Core 316, 52°28′N, 106°5′E). The northern core had higher amounts of biogenic silica (40 g SiO 2 per 100 g dry weight sediment) compared to the southern core, and increased deposition in the more recent sediments. Weight percent biogenic silica was lower in the southern core, ranging from approximately 20–30 g SiO 2 per 100 g dry weight sediment throughout the entire core. Trends in absolute microfossil abundance mirror those of biogenic silica, with generally greater abundance in the northern core (86–275×10 6 microfossils g −1 dry sediment) compared to the southern core (94–163×10 6 microfossils g −1 dry sediment).Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43073/1/10933_2004_Article_BF00735480.pd
