Rheological Properties And 3d Printing Behavior Of Pcl And Dmso2 Composites For Bio-Scaffold, Jae-Won Jang, Kyung-Eun Min, Cheolhee Kim, Chien Wern, Sung Yi

Mechanical and Materials Engineering Faculty Publications and Presentations

The significance of rheology in the context of bio three-dimensional (3D) printing lies in its impact on the printing behavior, which shapes material flow and the layer-by-layer stacking process. The objective of this study is to evaluate the rheological and printing behaviors of polycaprolactone (PCL) and dimethyl sulfone (DMSO₂) composites. The rheological properties were examined using a rotational rheometer, employing a frequency sweep test. Simultaneously, the printing behavior was investigated using a material extrusion 3D printer, encompassing varying printing temperatures and pressures. Across the temperature range of 120–140 °C, both PCL and PCL/DMSO₂ composites demonstrated liquid-like behavior, …

Biobank-Wide Association Scan Identifies Risk Factors For Late-Onset Alzheimer's Disease And Endophenotypes, Donghui Yan, Carlos Cruchaga, Et Al.

2020-Current year OA Pubs

Rich data from large biobanks, coupled with increasingly accessible association statistics from genome-wide association studies (GWAS), provide great opportunities to dissect the complex relationships among human traits and diseases. We introduce BADGERS, a powerful method to perform polygenic score-based biobank-wide association scans. Compared to traditional approaches, BADGERS uses GWAS summary statistics as input and does not require multiple traits to be measured in the same cohort. We applied BADGERS to two independent datasets for late-onset Alzheimer's disease (AD; n=61,212). Among 1738 traits in the UK biobank, we identified 48 significant associations for AD. Family history, high cholesterol, and numerous traits …

Covered Wagons To Ski Slopes: State Promoting Tourism During The 1947 Utah Prioneer Centennial, Jenny Showalter

The Thetean: A Student Journal for Scholarly Historical Writing

Crowds of skiers and ski enthusiasts gathered at a Utah resort on March 2, 1947. Excitement filled the brisk air as spectators watched professionals cut through the lingering winter snow to compete in the U.S. Slalom Ski Championships. Skiers from all over the nation were a blur as they expertly weaved between the gates.

The Slalom Ski Championships were only one of several athletic events held as part of the Pioneer Centennial celebrations …

Bernadotte: Behind His Decisions And Their Timing, 1810-1812, Timothy Wright

The Thetean: A Student Journal for Scholarly Historical Writing

In politics, sire, there is no friendship or hate-there are only duties to fulfill towards those people Providence has called upon us to rule." For Swedish Crown Prince Jean-Baptiste Bernadotte, this constituted his public reason for joining the Fifth Coalition against his former master as he marched against the French Army in 1813. Bernadotte needed to meet the requirements of his adopted country, untainted by his personal opinions. However, in addition to public considerations, friendship and hate play an important role in politics.

Nur Al-Din: Al-Malik Al-'Adil, Drew Mecham

The Thetean: A Student Journal for Scholarly Historical Writing

Though Saladin typically dominates discussion on Muslim resistance to the European Crusades, historian Carole Hillenbrand has noted that it was not Saladin but Nur al-Din Abu al-Qasim Mahmud Ibn 'lmad al-Din Zangi, hereafter Nur al-Din, who had a "reputation ... most glorious in the succeeding centuries in the Islamic world" Writing in the thirteenth century, Abu Shama noted that Saladin "modeled himself on all Nur al-Din's qualities of piety, chastity, decency, nobility and statecraft." The great Arab historian 'Ali 'izz al-Din lbn alAthir al-Jazari lbn al-Athir, known as lbn al-Athir, stated that his epitaph for Nur al-Din is written "in …

German Speakers In America During The Revolutionary War: Action, Assimilation, And Liberty, Heather Fife

The Thetean: A Student Journal for Scholarly Historical Writing

In 1768, Joseph II, afraid oflosing manpower and wealth within his own country, issued a decree forbidding his people to immigrate to lands outside the Holy Roman Empire. This effort to stem the tide of the American Auswanderung showed little result, as the annual number of German speaking emigrants to the New World remained in the thousands until 1775. At this time, the relationship between Great Britain and her subjects across the Atlantic was rapidly deteriorating. Although the reasons for this decay are numerous and varied, many British colonists resented the actions of the mother country. The end result, of …

No Dog In The Fight: East Tennessee And Its Response To The Succession Crisis, Douglas Marsh

The Thetean: A Student Journal for Scholarly Historical Writing

Despite arguments that the South fought in the 'War Of Northern Aggression' to protect the rights of the states, or to defend their homes and their freedom from a foreign power, it is clear slavery was the central issue of the American Civil War. Even the Confederate Vice-President Alexander Stephens declared that the inferiority of the Negro was the "immediate cause of the late rupture and present revolution" and the "cornerstone" of the Confederacy. The centrality of the slave issue becomes even clearer when noting that where slavery was not so engrained in the socioeconomic system, Confederate sympathy diminished.

"All Men Are Born Free And Equal:" Abolition Of Slavery In Revolutionary Massachusetts, Michael Lundberg

The Thetean: A Student Journal for Scholarly Historical Writing

In 1795 a law professor at the College of William and Mary wrote a letter to a clergyman who lived in Massachusetts. The professor was Judge St. George Tucker; the clergyman was the Reverend Dr. Jeremy Belknap of the Massachusetts Historical Society. In more than just a routine correspondence between friends, Judge Tucker was seeking advice, not just for himself, but for the entire state of Virginia. As he explained in his letter, Tucker had "observed, with much pleasure, that [slavery] has been wholly exterminated from ... Massachusetts" and sought to "learn what methods are most likely to succeed in …

"Better Wayes And Means Amongst The English, For The Attaining Of ... Health And Life": Indian Powers Of Choice In Conversion On Martha's Vineyard, Christina Gentile

The Thetean: A Student Journal for Scholarly Historical Writing

Nothing less than death was expected by herself and husband," English colonist Daniel Gookin wrote of a Wampanoag Indian in the mid-seventeenth century. The woman had been in labor for several days without sign of delivery, and, according to the other Indian residents of Martha's Vineyard, there was only one hope for her survival. "Send for a powow," the couple's relations exclaimed, "and use that help for release." The powwows, religious leaders known for their supernatural curing powers, often performed miracles in perilous circumstances and were thus always consulted in such situations. A powwow would be this woman's last chance, …

The Atlantic Charter And The Azerbaijan Crisis: An Analysis Of Lranian-U.S. Relations, Aren Sorensen

The Thetean: A Student Journal for Scholarly Historical Writing

The Azerbaijan crisis of 1945-46 has been called the 'Bunker Hill' of the Cold War; however, despite its important role in the Cold War it is a comparatively unknown event. The crisis was a particularly complex event, whose players included superpowers, small nations and ethnic minorities. The Azerbaijan crisis simultaneously involved dimensions of local, state and international relations-a familiar scenario through the duration of the Cold War. Iran's geo-strategic position, valuable oil reserves and history of confrontation with the colonial Soviet and British powers served as the genesis of the Azerbaijan crisis; however, the emergence of the United States as …

"They Could Not Guard Against It": The Failed U.S. Policy Response To German Sabotage At Black Tom Island, Benjamin Smith

The Thetean: A Student Journal for Scholarly Historical Writing

In the early morning hours of 31 July 1916, German agents successfully detonated a storage facility on an island in New York Harbor named Black Tom. The facility was filled with munitions meant for the Allied powers fighting against Germany in World War I. It was at that time the single most destructive subversive act ever perpetrated on U.S. soil. But it is not surprising that such an act occurred: the United States had no specialized counter-espionage agency and the area had relatively little protection. The remarkable thing is the miniscule amount of attention Black Tom, along with other instances …

Preface, Tara Westover

The Thetean: A Student Journal for Scholarly Historical Writing

For the past thirty-seven volumes, The Thetean has showcased the work of history students at Brigham Young University. The selection process is difficult: often staff members disagree and engage in spirited debates as they defend or critique various submissions. There are many moments when it seems the group will never reach consensus. With this in mind, I am always surprised to see the polished and pristine finished product. The completed journal betrays no hint of the discord that created it.

Two Heads Are Better Than One: Single Pilot Operation Threatens The Safety Of The Friendly Skies, Alexandria E. Rook

Arkansas Law Review

Boeing’s Maneuvering Characteristics Augmentation System (“MCAS”), an automated piloting system, is only supposed to handle aircraft operations in very specific circumstances. Despite devasting results with MCAS, Boeing has another automated piloting system on the horizon that poses even more grave risks: Single Pilot Operation (“SPO”). Boeing—along with Airbus—wants to replace one of the pilots in the cockpit of commercial airline flights with the new SPO technology it is developing. The FAA should not allow SPO technology to be implemented because it is premature, motivated by financial gain to the detriment of safety, and ignores the importance of professional judgment in …
