Michigan Tech Publications

Woody biomass serves as a renewable resource for various industries, including pulp and paper production, construction, biofuels, and electricity generation. However, the molecular mechanisms behind biomass traits are poorly understood, which significantly curtails the speed and efficiency of their improvement. We used activation tagging to discover genes that can positively affect tree biomass-associated traits. We generated and screened under greenhouse conditions a population of 2,700 independent activation tagging lines. A total of 761 lines, which had significantly and positively affected at least one biomass-associated trait, were discovered. The tag was positioned in the genome for forty lines which were affected …

Influence Of Redox Engineering On The Trade-Off Relationship Between Thermopower And Electrical Conductivity In Lanthanum Titanium Based Transition Metal Oxides, Mohammad El Loubani, Gene Yang, Seyed Morteza Taghavi Kouzehkanan, Tae-Sik Oh, Santosh Kiran Balijepalli, Dongkyu Lee

Faculty Publications

Discovery of new materials plays a critical role in developing advanced high-temperature thermoelectric (TE) applications. Transition metal oxides (TMOs) are one of the attractive candidates for high-temperature TE applications due to their thermal and chemical stability. However, the trade-off relationship between thermopower (S) and electrical conductivity (σ) limits the maximum attainable power factor (PF), thereby hindering improvements in TE conversion efficiency. To overcome this trade-off relationship, the emerging approach of the redox-driven metal exsolution in TMOs shows promise in improving both S and σ. However, the effect of metal exsolution with different particle sizes and …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Magnesium phosphate cement-based ultra-high-performance concrete (MPC-UHPC) develops strength rapidly but shows unsatisfactory ultimate strength (<150 >MPa). In this study, ultrafine fly ash (UFA) was incorporated in MPC-UHPC to improve mechanical properties. The effect of UFA content, varying from 0 % to 15 %, by weight of binder, on microstructure, fiber pullout behavior, mechanical strengths, flexural and tensile properties of MPC-UHPC reinforced with 2 vol% steel fibers was investigated. Experimental results indicate that the incorporation of 10 %–15 % UFA with mean particle size of 1.4 µm was effective in reducing porosity and microcracks of binder matrix and fiber–matrix interface, thereby …

Personalized Learning Path Problem Variations: Computational Complexity And Ai Approaches, Sean A. Mochocki, Mark Reith, Brett J. Borghetti, Gilbert L. Peterson, John Jasper, Laurence D. Merkle

Faculty Publications

E-learning courses often suffer from high dropout rates and low student satisfaction. One way to address this issue is to use personalized learning paths (PLPs), which are sequences of learning materials that meet the individual needs of students. However, creating PLPs is difficult and often involves combining knowledge graphs (KGs), student profiles, and learning materials. Researchers typically assume that the problem of creating PLPs belong to the nondeterministic polynomial (NP)-hard class of computational problems. However, previous research in this field has neither defined the different variations of the PLP problem nor formally established their computational complexity. Without clear definitions of …

Constitutional Challenges To Caps On Tort Damages: Is Tort Reform The Dragon Slayer Or Is It The Dragon?, Kathryn L. Vezina

Maine Law Review

Liability insurance consumers are convinced the dragon is only sleeping. Because insurance has become a near necessity for businesses, professionals, and municipalities, it is no surprise that fears of the return of insurance unavailability and prohibitive cost cause the boldest policyholders to break out in a cold sweat. In many states, this fear has prompted legislative changes in the civil justice system—tort reform, as a sure-fire way to kill the insurance-crisis dragon. One such tort reform is a statutory limitation on tort damages. In Maine, a legislative proposal capping noneconomic tort damages in medical negligence cases at $250,000 has received …

Rethinking The History Of The Seventeenth-Century Colonial Ordinance: A Reinterpretation Of An Ancient Statute, Mark Cheung

Maine Law Review

In 1648, the Massachusetts colonial government ordered into print The Book of the General Laws and Libertyes that included an ordinance, commonly known as the Colonial Ordinance. The Ordinance extended private seashore property rights to the low water mark but to no more than one hundred rods beyond the high-water mark. The 1648 Ordinance replaced an earlier version enacted in the Body of Liberties of 1641. While both versions of the Ordinance enumerated public rights of fishing, fowling, and navigation in the foreshore, the 1648 Ordinance provided the critical language extending the private boundary to the low water mark. Prior …

Expanding Public Access By Codifying The Public Trust Doctrine: The Massachusetts Experience, William L. Lahey, Lauren Sandler Zurier, Kenneth W. Salinger

Maine Law Review

The Commonwealth of Massachusetts is dramatically expanding public access to the coast through statutory and regulatory codification of the public trust doctrine. Is this legislative and administrative experiment relevant to other states, particularly to Maine? The initial answer to this question may depend on the meaning of the Bell v. Town of Wells decision. For better or for worse, Massachusetts jurisprudence set the course followed by the majority of the Maine Supreme Judicial Court in Bell. To some, including several of the authors in this symposium, the bearing of the Massachusetts courts leads to a civic wasteland where the public's …

Public Trust, Public Use, And Just Compensation, Alison Rieser

Maine Law Review

In its recent decision, Bell v. Town of Wells, the Maine Law Court declined to grapple with one of the major legal conceptual problems presented by the case. The court failed entirely to reckon with the intersection of two competing, dynamic principles of American property law; these principles are increasingly significant in an era of growing conflict between public and private interests in land and natural resources. The first principle protects particular expectations of private owners of property through application of the just compensation (or "takings") clause of the fifth amendment. The second principle recognizes that certain property is held …
