Storage of Pine Tree Substrate Influences Plant Growth, Nitrification, and Substrate Properties
Pine tree substrate (PTS) is a relatively new substrate for container crop production. There are no detailed studies that elucidate how storage time impacts PTS chemical, physical, and biological aspects. The objective of this research was to determine how PTS storage time influenced PTS chemical …

Substrate curvature measurement system
… circuits (VLSI). During this process a substrate is coated with a thin film to protect the micro circuitry formed on the substrate. Due to the differences in thermal expansions between film and substrate, mechanical stresses can develop which may lead to deformation of the substrate …

Rational manipulation of substrate-supported graphene by heterogeneity of substrate surface and material composition
… graphene-based devices graphene is adhered to a substrate that influences its performance, rather than being present in a free standing form. The interaction of graphene with these substrates can lead to deformations that give rise to out-of-plane architectures with new properties such as …

Substrate integrated waveguide antenna systems
… of research has been done to the design of substrate integrated waveguide (SIW) components in the mm-wave and microwave range. SIW has many advantages in comparison to conventional waveguides and microstrip lines, such as compact and planar structure, ease of fabrication, low radiation loss, …

Investigation of the hazards of substrate current injection: transient external latchup and substrate noise coupling
Substrate current injection is the origin of external latchup and substrate noise coupling. The trigger current for external latchup depends on the duration of the trigger event. A physics-based model is provided to model the effects of aggressor to victim spacing and orientation on transient …

Shape-Engineering Substrate-Based Plasmonic Nanomaterials
… a series of syntheses related to the design of substrate-based nanoparticles whose size, shape and composition are controllably engineered to a desired endpoint. The experimental methods are based on a template-mediated approach which sees chemical modifications made to prepositioned thermally …

Microwave defrosting on a metal substrate
Microwave defrosting on a metal substrate was investigated theoretically and experimentally for application to refrigerator evaporator coils. Methods to improve the intrinsically poor microwave absorptivity of frost-on-metal substrate were explored. Experimentation was done to eliminate the …

Substrate recognition by the 26S proteasome
… that specific signals (called degrons) on the substrates are recognised by the proteasome, including ubiquitin and a disordered region. The main focus of this thesis is to better understand how the ubiquitin containing degron binds to intrinsic ubiquitin receptors in the 26S proteasome and how …

Energetics of substrate unfolding by ClpA
… and uses the energy of ATP hydrolysis to unfold substrates and translocate them to ClpP for proteolysis. ClpA's in vivo contribution to cellular maintenance is small, but it serves as an ideal model for energy-dependent molecular machines. The goal of this work is to describe the energetics of …

A substrate for accountable layered systems
… can be ameliorated by erecting the system on a substrate that implicitly supports tracing the behavior of the system to the data and through the procedures that produced that behavior. Good traces make the system accountable; it enables the analysis of success and failure, and thus enhances the …

Mechanisms of contact stabilization substrate removal
… carbohydrate organic colloids and a combination substrate were separately studied to determine if the type or classification of substrate colloids is a factor in the colloid-sludge interaction. Albumin, potato starch, and jack bean meal were the substrates chosen. Two series of studies were …

Azotobacter vinelandii Nitrogenase: Multiple Substrate-Reduction Sites and Effects of pH on Substrate Reduction and CO Inhibition
… the Fe protein and the MoFe protein. The site of substrate binding and reduction within the Mo-nitrogenase is provided by a metallocluster, the FeMo cofactor, located in the a-subunit of the MoFe protein. The FeMo cofactor's polypeptide environment appears to be intimately involved in the delicate …

The Substrate and Regulator of Acetyltransferase San
… and human, but little is known about its substrates or upstream regulators. To identify San substrates, I performed affinity purification and demonstrated that tubulin is a San substrate. Tubulins are the building blocks of microtubules, which display dynamic instability. By regulating the …

Substrate Integrated Waveguide Horn Slot Antenna Array
Substrate integrated waveguide (SIW) is a rectangular dielectric-filled waveguide, which is synthesized in a planar substrate with arrays of metallic vias to realize bilateral side walls and its transitions with planar structures. These vias act as walls of the waveguide supporting current flow, …

Biological wastes as plant growth substrate amendments
… waste was investigated as a selective growth substrate amendment in the field, in glasshouse and in storage trials against Sclerotinia disease of Helianthus tuberosus, Phytophthora fragariae disease of Fragaria vesca and Fusarium disease of Dianthus. Results showed that addition to shellfish …

Integrated Circuit Substrate Modeling for Noise Analysis
In addition, the need for the extension of this methodology to the frequency-dependent case, where electromagnetic effects such as displacement current and skin effect cannot be assumed negligible, has been argued and demonstrated in this dissertation.
