LRFD evaluation of full-scale metal building rigid frame tests
(Virginia Tech, 1996-01-05)see document -
Lubrication Forces in Polydimethylsiloxane (PDMS) Melts
(Virginia Tech, 2011-07-07)The flow properties of polydimethylsiloxane (PDMS) melts at room temperature were studied by measurement of lubrication forces using an Atomic Force Microscopy (AFM) colloidal force probe. A glass probe was driven toward ... -
The Lucidity of Place
(Virginia Tech, 2001-09-07)This project is a building in a town, for a town. Public, semi-public, and private spaces are designed on a narrow site. A simple, repeated form makes the building a container for filtered sunlight. A secondary form is ... -
Luck Egalitarianism and Democratic Equality
(Virginia Tech, 2007-05-11)Luck egalitarianism is the view that justice requires that we hold people accountable for the choices that they make but not the circumstances that they find themselves in. My aim in this thesis is to reject luck egalitarianism. ... -
Ludgate Circus: St. Paul's AS prospect
(Virginia Polytechnic Institute and State University, 1991)Why does a London smog heavy with the dark smell of diesel on a drizzly gray afternoon bring a keen sense of deja vu, o spasm of Anglophilia, to one who grew up in the Pacific Northwest of the United States? Perhaps it is ... -
Ludwik Fleck and his concept of a scientific fact
(Virginia Tech, 1995-08-30)In this thesis, I explore the concept of a scientific fact through the work of Polish physician Ludwik Fleck (1896-1961). Fleck has had an alleged influence upon contemporary philosophy of science, prinlarily through ...

Luminescent Properties of Anthracene-based Metal-Organic Frameworks
(Virginia Tech, 2016-06-30)Metal-organic frameworks (MOFs) are crystalline materials composed of metal clusters and organic ligands. MOFs that exhibit photoluminescence are promising materials for a broad range of applications. Due to their structural ... -
Luminous Land of Phon
(Virginia Tech, 2019-07-10)This thesis, Luminous Land of Phon, explores how architectural spaces, even interior spaces, interact with nature along different dimensions. Light and sound are the two very powerful elements of nature and are the focus ... -
Lunar Mission Analysis for a Wallops Flight Facility Launch
(Virginia Tech, 2008-09-12)Recently there is an increase in interest in the Moon as a destination for space missions. This increased interest is in the composition and geography of the Moon as well as using the Moon to travel beyond the Earth to ... -
Lunar Robotic Precursor Missions Using Electric Propulsion
(Virginia Tech, 2006-10-23)A trade study is carried out for the design of electric propulsion based lunar robotic precursor missions. The focus is to understand the relationships between payload mass delivered, electric propulsion power, and trip ... -
Lunar: A User-Level Stack Library for Network Emulation
(Virginia Tech, 2004-02-24)The primary issue with developing new networking protocols is testing how the protocol will behave when deployed on a large scale; of particular interest is how it will interact with existing protocols. Testing a protocol ... -
LWFG: A Cache-Aware Multi-core Real-Time Scheduling Algorithm
(Virginia Tech, 2012-06-08)As the number of processing cores contained in modern processors continues to increase, cache hierarchies are becoming more complex. This added complexity has the effect of increasing the potential cost of any cache misses ... -
Lying in children as a function of adult monitoring
(Virginia Tech, 1990-11-05)A procedure similar to correspondence training was used to assess the propensity of children to lie under varying levels of adult monitoring. Thirteen children selected pieces of food to be eaten later as a snack, and ... -
Lyme Disease and Forest Fragmentation in the Peridomestic Environment
(Virginia Tech, 2020-05-14)Over the last 20 years, Lyme disease has grown to become the most common vector-borne disease affecting Americans. Spread in the eastern U.S. primarily by the bite of Ixodes scapularis, the black-legged tick, the disease ... -
Lyme Disease Emergence in Virginia: An Examination of the Demographic and Environmental Variables Correlated to the Spatial Pattern of Disease Incidence
(Virginia Tech, 2013-06-06)Since its initial identification in 1975, Lyme disease has become a public health concern in the U.S. Increased concern is sparked by the rapid rate at which the disease is emerging into new areas. One area of disease ... -
Lyocell Fiber-Reinforced Cellulose Ester Composites - Surface and Consolidation Considerations, and Properties
(Virginia Tech, 1999-09-24)The objective of this thesis was to further develop the polymer composite system consisting of cellulose acetate butyrate (CAB) and high modulus, continuous, regenerated cellulose fiber (lyocell). Of particular concern ... -
Lyocell Fiber-Reinforced Cellulose Ester Composites-Manufacturing Considerations and Properties
(Virginia Tech, 1999-09-08)Biodegradable thermoplastic composites were prepared using high modulus lyocell fibers and cellulose acetate butyrate (CAB). Two reinforcement fiber types: fabric and continuous fiber tow were used. Fabric had advantages ... -
Lysine and Glycyl-L-Sarcosine Absorption Across Ovine Forestomach Epithelium In Vitro
(Virginia Tech, 1996-08-20)Lysine absorption by ruminal and omasal epithelia was studied using parabiotic chambers that were sampled for 60-min. Lysine appearance in serosal buffers and the accumulation of lysine in tissues increased linearly (P < ...
