Undergraduates In The News
Arctic tundra vegetation has been dynamic over time, especially as the present-day climate change warms the Arctic regions at twice the rate of the global average. In general, the “greenness” of arctic tundra vegetation has been increasing throughout the Arctic (e.g. Alaska, Canada, and northern Russia) over at least the past 5 decades, suggesting broad environmental changes in these regions.
Methane from natural gas is a critical resource, but the difficulty of transporting natural gas has resulted in underutilization of methane. In oil wells, excess methane is flared because it is not cost-effective to capture, releasing large amounts of CO2 into the atmosphere.
United States Navy vessels are susceptible to intergranular corrosion due to a humid, chlorine-saturated environment. The presence of copper metal accelerates IGC growth in grain boundaries of aluminum alloys, decreasing the aluminum’s structural integrity and lifetime. To reduce cost and labor of repair and to increase longevity of vessels, resistant alloys are to be employed.
This study aimed to define and then compare two sets of vocal quality terms commonly implemented by singing professionals, front vs back and light vs dark, using acoustic, aerodynamic, and perceptual measurements, as well as a survey asking voice professionals to rate and define them.
After the Roman dictator Sulla besieged and colonized Pompeii in 89 BCE, he instituted Roman-style elections that continued until the city’s demise in the 79 CE eruption of Mt. Vesuvius. Modern historians know this because when Pompeii was rediscovered in the late sixteenth century, they found electoral notices painted on the walls.
Coronary artery disease (CAD) caused by atherosclerosis is the leading cause of death worldwide. This disease is characterized by the buildup of atherosclerotic plaque made of substances including lipids and cellular waste. Succeeding plaque buildup, Smooth Muscle Cells (SMCs) migrate and proliferate to form a fibrous cap that stabilizes the plaque.
As the complexity of biological systems and tunability of synthetic materials are further understood, opportunities for engineers to design synthetic materials that interact with the natural world seamlessly are brought to light. For this project, synthetic materials will contain synthetic polymers and complementary peptides.
Over the past decade, there has been a transition from conventional biomaterials to materials with injectability potential; both for minimally invasive therapeutics and for 3D printing applications.To address this problem, we have designed a biomaterial capable of recapitulating the complex extracellular matrix (ECM) microenvironment and capable of injectability.
In temperate regions, an organism’s ability to rapidly acclimate to varying seasonal temperatures, particularly the subfreezing cold of winter, is essential for its survival. Although less famous than hibernating bears and migrating birds, the fruit fly, Drosophila melanogaster, must also overcome winter’s challenges. One of the mechanisms implicated in D.
Acute kidney injury (AKI) is a condition in which the kidney experiences a sudden loss of function, and is associated with increased mortality. Many cancer patients develop AKI as a common complication of Cisplatin, an effective chemotherapeutic drug in the treatment of about 20% of cancer patients.
Head and Neck Squamous Cell Carcinoma (HNSCC) refers to cancers arising mainly from the squamous cells in the oral cavity and throat. This year, it is expected that over 65,000 people in the United States alone will develop HNSCC, and it will claim nearly 14,000 lives.
Paleontology, the study of past life, is a fairly recent discipline that originated in Western Europe in the late-18th century. Paleontology in Russia parallels the West historically, with contemporaneous proliferation throughout the 19th century. The understanding of the heritage of an region is valuable in conceptualizing space and place.
A watershed in the history of his sculptural practice, Alexander Calder’s first monumental stabile, Teodelapio, emerged from a series of favorable circumstances in 1962. For Spoleto, Italy’s open-air exhibition of fifty-three international sculptors, Sculpture in the City, Giovanni Carandente commissioned Calder to design a “triumphal arch” for the ancient hillside town.
The activation of abundant small molecules such as dioxygen (O2), dihydrogen (H2), and carbon dioxide (CO2) for green energy applications is an area of chemical research that has been studied for several decades.¹ The challenge in activating these molecules is due to their relative inertness posing significant energetic barriers.
The Papers of George Washington transcribes manuscripts from and to George Washington that are often difficult for today's readers to read in order to make those manuscripts accessible. PGW also annotates the transcriptions with footnotes to help readers interpret the manuscripts.
