Nitrogen and Carbon Stable Isotope Analysis of Holocene Pigs from Liang Bua (Flores, Indonesia)
(2021)In this study, pigs from Liang Bua (Flores, Indonesia) are examined using nitrogen and carbon stable isotopes to explore possible changes to their diet over the past ~5,000 years. This temporal period is of particular ... -
Nitrogen removal efficiencies in constructed wetlands
(2019)This thesis summarizes the usage of constructed wetlands in reducing nitrogen loaded anthropogenic waste water, sourcing a collection of results of outside literature. The literature used in this thesis was found from ... -
NMR studies of lignin models, derivatives and bleaching effluents
(1995)NMR problems related to assignment techniques and relaxation restrict the use of NMR in the structural analysis of lignin. These problems have been addressed in three practical studies in this thesis involving a lignin ... -
NMR study of aqueous tetraalkylammonium silicates
(1994)Silicon-29 nuclear magnetic resonance (NMR) spectroscopy has been used to investigate the equilibrium distribution and kinetics of silicate oligomers in aqueous tetraalkylammonium silicate solutions. Certain tetraalkyl ... -
No man is a failure who has friends : the role of adaptive inferential feedback in hopelessness depression / Lize R. Jalbert. --
(2004)The theory of hopelessness depression (Abramson, Metalsky, & Alloy, 1989) states that the presence of the psychological state of hopelessness is a sufficient cause for the development of a specific subtype of depression ... -
Non-collocated control of vibration of a three-DOF structure using the electromagnetic vibration absorber
(2007)Vibration control is very important in many areas including machine operation and daily life. Semi-active vibration control integrates a tuning control scheme with a tunable vibration absorber for suppression of vibration ... -
Non-destructive evaluation for boreal tree species utilizing acoustic testing
(2017)Standing trees pertain a level of uncertainty, in regards to yield and end-use. Thus, it may be feasible to analyse the forest, at the ground level, in order to allocate the timber resources accordingly. Through stress-wave ... -
Non-destructive testing to monitor the strength increase of electrokinetically treated soil
(2018)Electrokinetics in geotechnical engineering is used to increase the shear strength of soft soils and the load carrying capacity of piles embedded in these soils. This is achieved by decreasing the water content of the soil ... -
Non-Indigenous educator and Indigenous student relations: rooting ourselves in their values
(2017)Assimilative and integrative policies remain part of Canada‟s dominant narrative and continue to inform non-Indigenous educators‟ relations with their Indigenous students. Counter narratives of Indigenous student and ... -
Non-standard analysis / by Geraldine S. Service
This thesis is a study of several theories of Non-standard Analysis. Particular attention is paid to the theories presented by A. Robinson and E. Zakon. Chapter I contains background information from Mathematical ... -
Nonlinear adaptive control for robust wide speed range operation of IPMSM drives
(2015)Various applications, including robotics, spindle drives, machine tools, etc. rely on accurate, reliable controllers to deliver the required drive performance. With recent advances in magnetic materials and semiconductor ... -
Nonlinear controller design for a buck converter
(2006)This thesis presents five different nonlinear control techniques for voltage regulation of a DC-DC buck converter operating in continuous conduction mode. A state space averaging model is derived from a non-ideal buck ... -
Nonlinear dynamics of railway wheelsets incorporating randomness
(2007)The thesis is to investigate the dynamic behavior of a single-axle railway wheelset and identify its chaotic behavior by means of time history, phase portrait, Lyapunov exponents, information dimension, bifurcation diagram ... -
A nonlinear energy sink with energy harvester
(2014-12-11)The transfer of energy between systems is a natural process, manifesting in many different ways. In engineering transferable energy can be considered wanted or un- wanted. Specifically in mechanical systems, energy transfer ... -
Nonlinear mathematical and numerical modeling of the effect of temperature on membrane pore size
(2022)Due to the growth of the global population, water stress has risen sharply. However, water stress in high latitudes is not only due to population growth but also to low local temperatures. Numerous studies have shown ... -
Nonlinear transient analysis based on power waves and state variables
(2010)Muhammad Ershadul Kabir was born in Chittagong, Bangladesh on July 15, 1982. He received the Bachelor of Science in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology (BUET) ... -
Nonlinear transient analysis based on wave digital filters
(2014-01-22)Simulation of large circuit networks is a CPU-time and memory consuming task. Computer clusters and multi-core processors have become common but algorithms must be parallelizable to fully take advantage of these architectures. ... -
North American pinewood nematode disease in China
(2019)The pinewood nematode (Bursaphelenchus xylophilus) is an important alien invasive species in China. This pinewood nematode poses a serious threat to Chinese forests. It does have an important impact on forestry, including ... -
Northern exposure: a comparison study of Alaska and Yukon models of measuring community wellbeing
(2015-02-02)The main objective of this study is to examine models of measuring community wellbeing in Alaska and Yukon to determine if they were developed with the input of residents and if these models reflect local living conditions. ... -
Northern lights : a history of Thunder Bay Hydro / by David Leo Black.
(1994)Electricity has played an important role in the economic and social development of Ontario cities, and Port Arthur and Fort William located at the head of the Great Lakes are no exception to this rule. Industrial development ...
