Directing ecological succession : the role of competition in restoring semi-arid grasslands dominated by invasive plants

Creator:: Mangla, Seema
Abstract:: Successful ecosystem restoration requires an understanding of the ecological processes directing succession. One of the challenges in the semi-arid grasslands of western United States is replacement of native species by invasive annual grasses. Solutions to this problem require identifying and manipulating ecological processes that direct succession to favor desired vegetation....

A comprehensive integration of first year engineering education

Creator:: Shuman, Matthew W.
Abstract:: Retention of engineering students is a problem for many universities, especially during the first year. The problem of introducing students to engineering while increasing retention rates has recently been addressed by many different universities. Implementing novel lab structures, adjusting the lecture to incorporate more effective teaching techniques, and using orientation...

Full Text:: Strength Elements Between Pargasitic Amphibole and Silicate Melts. Abstract approved: Roger Nielsen

Photobiological hydrogen production from the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in sol-gel processed silica

Creator:: Dickson, David J.
Abstract:: Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...

Physiological, proteomic, and whole-genome transcriptional responses of Nitrosomonas europaea to heavy metals (Zn²⁺,Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide : identification of heavy metals and cyanide stress response genes

Creator:: Park, Sunhwa
Abstract:: Nitrosomonas europaea (ATCC19718) participates in the biological removal of nitrogen from wastewater by oxidizing ammonia to nitrite, the first step in nitrification. This bacterium is sensitive to heavy metals (Zn²⁺, Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide, compounds commonly encountered in wastewater treatment plants. Therefore, we characterized physiological and transcriptional responses...

Integrating functional trait frameworks into restoration : the role of seed and seedling traits in recruitment success

Creator:: Larson, Julie E.
Abstract:: Seeding is a vital tool to facilitate recovery of degraded ecosystems, but low seedling recruitment rates limit the utility of this practice in a range of ecosystems across the globe. Plant functional traits impact individual fitness through effects on growth, reproduction and survival. Consequently, seed and seedling trait variation among...

Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

Creator:: Tseng, Chih-Heng
Abstract:: Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

Arc distribution and motion during the vacuum arc remelting process as detected with a magnetostatic approach

Creator:: Woodside, Rigel
Abstract:: Currently, the temporal arc distribution across the ingot during the vacuum arc remelting (VAR) process is not a known or monitored parameter. It is has previously been shown that arcs can spatially constrict during VAR, and this constriction can lead to undesired defects in the material. Additionally, correct accounting for...

Magmatic processes at mid-ocean ridges : evidence from lavas and melt inclusions from the Southeast Indian Ridge, the Endeavour Segment of the Juan de Fuca Ridge, and the northern East Pacific Rise

Creator:: Sours-Page, Rachel E.
Abstract:: Magmatic processes control the chemical compositions of all lavas erupted at mid-ocean ridges. In this thesis, I present studies of magmatic processes on three different mid-ocean ridges to determine which processes are in action and to what extent each has affected the chemistry of mid-ocean ridge basalts at each location....
