Nucleation seeding in metakaolin geopolymers
… validated by studying the effects of external seeding on a synthesized aluminosilicate-sodium hydroxide (AlSi-NaOH) geopolymer. Fourier transform infrared spectroscopy (FTIR) revealed that the AlSi-NaOH geopolymer forms two products - one similar to MK-NaOH geopolymer product and the other …

A fast seeding technique for k-means algorithm.
… and quality of k-means. One of the most popular seeding techniques is k-means++ initialization, but this method needs k passes over the dataset. The goal of this thesis is to propose a new seeding technique which chooses the initial centers much faster than k-means++.

Mediating Chana: Seeding Synergies between Doves and Development
For almost a century, domestication of zebra doves for birdsongs has given Chana the reputation as the emerging Southeast Asian capital of zebra doves. In this rural district in the southern coast of Thailand, the doves are not only worth more than gold but also hold higher values in the local …

Crystal seeding for the control of sludge properties
The object of this investigation was to determine, by the concept of specific resistance, the effect of certain variables on the filterability of calcium sulfate sludge resulting from lime neutralization of synthetic, return sludge seeded, sulfuric acid samples, The variables investigated were rate …

Post-island futures : seeding territory for Tuvalu's fluid atolls
… waters of climate change, this thesis posits 'seeding' territory as an alternative. The project explores the propagation of the architectural 'seed' as a way to 'grow' territory in the context of migratory populations and unstable geographies. The seeds consider territory both in the sense of …

Evaluating Seeding Galveston: Assessing Food Security and Health-Related Outcomes
… program within community organizations. Seeding Galveston, a relatively young non-profit organization on Galveston Island, seeks to increase food security for low-income residents and provide a sustainable food source for all. Seeding Galveston requires an evaluation to determine how to …

Seeding Sovereignty: Sensory Politics and Biodiversity in the Karen Diaspora
<p>This dissertation traces the sensory and political dimensions of Karen refugees' co-movements with their seeds, plants, and agricultural practices in exile. It also tentatively explores understandings of sovereignty beyond the frame of the Westphalian nation-state through engagements with seed …

Genetic gain X management interaction in soybean: seeding rate effect
… the last 80 years were evaluated at high and low seeding rates in research trials conducted in Illinois, Indiana, Minnesota and Wisconsin. In Illinois and Indiana, 57 maturity group III cultivars released between 1923 and 2007 were compared, and in Minnesota and Wisconsin, 59 maturity group II …

Gypsum seeding to prevent scale formation and improve separation efficiency
… it was to investigate the effect of gypsum seeding on gypsum separation efficiency. Synthetic brine solutions were used in this research because they allowed an in-depth understanding of the gypsum bulk crystallization process and scaling tendency without the complexity of industrial brines. …

Soybean Growth and Yield Response to Seeding Rate in Virginia
… generating interest from growers to reduce seeding rates to the lowest possible level that does not affect yield. Research indicates that greater seeding rates are needed to maximize yield under low-yielding environments and less seed is needed in high-yielding environments, but this has not …

Primordial black hole seeding from hybrid inflation : the direct integration approach
… results do not directly show the plausibility of seeding supermassive black holes, but the shape of the power spectrum suggests that further work might yield positive results.

Characterization and Cell-Seeding of Decellularized Adipose Tissue Foams for Wound Healing
… DAT foams using traditional static cell-seeding techniques. Therefore, cell-seeding studies were performed in an attempt to enhance cell infiltration into the central regions of the foams. dsDNA content and cell density were quantified in response to various seeding methods, scaffold …

Development of a seeding pellet system for use in soil conservation forestry
… that has been touted in recent years is drone seeding, the effectiveness of which is contingent upon the existence of effecting seeding pellet systems. Systems developed by private companies have not been rigorously reviewed, nor is much of the data available on their success rates, …

Seeding of Titanium Surfaces and Nitinol Stents with Blood-Derived Endothelial Cells
… devices. We developed a novel cell therapy for seeding autologous endothelium onto blood-contacting vascular stents at the point of care to reduce thrombosis and stent restenosis. The proposed research tested the following hypotheses: (1) autologous endothelial cells (ECs) can spread on titanium …

Cell seeding and proliferation simulations to plan experiments of multicellular osteogenic systems
… geometry using micropatterned substrates, or via seeding densities that allow for cell spreading. Due to the complexity of biological systems, typically, researchers use patterned substrates and inhibit proliferation, or observe proliferation on unpatterned substrates to isolate and understand the …

Engineered microvasculature platforms to study tumor-host-matrix interactions during metastatic seeding
Distant metastases, which result in >90% of cancer related deaths, is enabled by hematogenous dissemination of tumor cells via the circulation. In particular, tumor cell extravasation is thought to be an essential and potential rate-limiting step, as most metastases are found in the extravascular …
