Montana State University – Northern is a public state university, part of the Montana State University System, located in Havre, in the U.S. state of Montana. Montana State University – Northern was known as Northern Montana College prior to the restructuring of Montana's public university system. It has an operating budget for fiscal year 2007 of $12,540,000. In 1913, the Montana State Legislature approved the establishment of the Northern Montana Agricultural and Manual Training School at Fort Assinniboine, six miles southwest of Havre, but no money was actually appropriated. The State Legislature amended their original act in 1927 to include certain academic subjects and in 1929, the Legislature appropriated funds to establish the college as a branch of the University of Montana . Northern Montana College opened its doors in September 1929 in temporary quarters in Havre High School, and moved to its present campus in 1932.In 1994, the Montana University System elected to realign its smaller campuses with the two main universities, University of Montana in Missoula and Montana State University in Bozeman. Northern Montana College was renamed Montana State University – Northern on June 1 of that year. Wikipedia.

Cellulose has become atopic of keen research interest due to its potential as a substitute ingredient in the production of petroleum products. Cellulose is a unique stereo regular, chiral, biocompatible and reactive polymer which at the same time constitutes an abundant and renewable natural resource. However, the efficient conversion of cellulose towards speciality polymers and its hydrolysis to biofuels is severely hindered by the crystallinity inherent in native cellulose. A few solvent systems have been found effective for molecular dissolution of cellulose, but they operate under rather strict conditions of composition and temperature. We studied the dissolution of solid cellulose in aqueous Na OH solutions with the aim to elucidate the transport phenomena governing the dissolution process. Source

Alternative ways of converting crude glycerol from biodiesel production to value-added products are in high demand to solve the issue of increasing glycerol surplus. Propylene glycol (PG) and ethanol are examples of valuable chemicals that had been successfully produced from glycerol through in situ hydrogenolysis in our previous studies. This study aimed to determine the optimum conditions for maximizing the yields of PG and ethanol through in situ hydrogenolysis of glycerol. Depending on the targeted products, the optimum process conditions, obtained through statistical analysis and experimentally confirmed with a high PG yield of 47.2%mol, were 220°C, 51 min and 1.0:1.0 water to glycerol mass ratios (WGMR). However, the complex reactions involved in the production of ethanol lead to inconclusive results for the optimization. The key to maximizing the PG yield from in situ hydrogenolysis of glycerol is to operate the system at mild reaction temperatures (e.g., 220°C) at which the further conversion of PG to ethanol is slowed. Meanwhile, a 1:1 mixture of water and glycerol minimizes the side reactions and improves the PG formation. The ethanol production alone from glycerol does not seem economically justified for large scale production due to its low yield. However, co-production of PG and ethanol might be a viable solution. © 2015 Taylor & Francis. Source

Background: Propylene glycol (PG) is one value-Added product that can be produced from glycerol through catalytic hydrogenolysis, which conventionally requires external supply of costly hydrogen. This study investigated PG preparation from glycerol through the acetol pathway by Raney nickel-catalyzed hydrogenolysis without an external hydrogen supply. Results: Experiments were designed to examine the glycerol conversion with specific reactant formulations. Thermodynamic analysis was also conducted on species at equilibrium to investigate the pathway from another angle. Conclusion: Acetol is the intermediate in glycerol conversion to PG and hydrogen is internally generated from reformation reactions. The reaction rate of acetol hydrogenolysis dictates the PG yield. PG would be further converted to ethanol through hydrogenolysis if the reaction time were extended. © 2012 Future Science Ltd. Source

Akene metathesis of unsaturated FAME with ethylene is a powerful synthesis reactor to produce terminal alkenes which can be used for synthesis of polymers and other valuable compounds. Although commercial metathesis catalysts have been proven to be efficient in converting pure FAME, this process has not been used effectively in a mixture of methyle esters like biodiesel. Moreover, there has been no study in the literature that has used supercritical ehtylene in alkene metathesis. We anticipate to minimize mass transfer limitations with the use of supercritical ethylene during metathesis with FAME. In this study FAME derived from camelina oil, which contains as much as 90S% unsaturated components, was allowed to react with supercritical ethylene at room temperature in the presence of Grubb's catalyst. A high pressure syringe pump is used to deliver 750 psi of ethylene and the reaction is performed in a 500 mL high pressure and high temperature reactor fro 4 hours. Different commercial first and second generation Grubbs catalysts were tested. Depending on the nature of the catalyst, self metathesis of FAME, isomerization and cyclization were observed as well at varying degrees as evidenced by GC/MS analyses. Percent conversion of unsaturated FAME as high as 87% was observed. Source

During the past decade, Lebanon has experienced a large number of severe wildfires that have had significant social and ecological consequences. In this context, the assessment of wildfire risk is important to support planning of fire prevention measures and risk mitigation. The purpose of this study was to assess the spatial distribution of wildfire risk in Lebanon. The objectives were to identify and map (a) wildfire hazard, (b)wildfire vulnerability, and (c) wildfire risk. We developed a model using geospatial biophysical and climatic data and Geographic Object-Based Image Analysis (GEOBIA). Development of the wildfire hazard map included classification of forest fuel type, combustibility, and fire spread whereas the vulnerability map included classification of demographic vulnerability (i.e., boundary, occupation and scatter indicators) and forest vulnerability (i.e., environmental and replacement values). The resulting geospatial map of wildfire risk provided important information for potential use in fire risk management. © 2015 American Society for Photogrammetry and Remote Sensing. Source
