Is the Indian Ocean MOC driven by internal wave breaking?
… Indian Ocean Meridional Overturning Circulation (MOC) using hydrographic data (Part I), and the interaction between a broad band internal wave field and a mean flow using idealized numerical simulations (Part II). The main objective of this work is to quantify how much energy is needed to drive …

LWR fuel reactivity depletion verification using 2D full core MOC and flux map data
Experimental quantification of PWR fuel reactivity burnup decrement biases and uncertainties using in-core flux map data from operating power reactors has previously been conducted employing analytical methods to systematically determine experimental fuel reactivities that best match measured …

Medial olivocochlear efferent (MOC) effects on stimulus frequency otoacoustic emissions (SFOAEs) and auditory-nerve compound action potentials (CAP) in guinea pigs
In humans, SFOAEs can non-invasively assess MOC strength and, may predict the MOC reduction of damage from traumatic sounds. However, the functionally important MOC effect is inhibition of auditory-nerve (AN) responses. Understanding the relationship between MOC effects on SFOAEs and AN CAPs is …

Frequency specificity of contralateral, ipsilateral and bilateral medial olivocochlear acoustic reflexes in humans
… manner through the medial olivocochlear (MOC) efferent pathway, but the degree of MOC frequency specificity in humans is poorly understood. This thesis investigates the tuning properties of the human MOC acoustic reflex at different cochlear frequency regions and with different …

Profiling mucinous ovarian cancer and comparisons with tumours of the gastro-intestinal tract: identification of markers for diagnosis, prognosis, and treatment targets.
Mucinous Ovarian Carcinoma (MOC) is a rare histological subtype, comprising 3-4% of all epithelial ovarian cancers. The majority (~80%) of patients are diagnosed at early stage, International Federation of Gynecology and Obstetrics (FIGO I/II), with a good prognosis after primary surgery. The key …

Slow modulation of cochlear response by the olivocochlear efferent system elicited by sustained noise or threshold elevation in the contralateral ear
… pig. We found evidence of medial olivocochlear (MOC) effects on two timescales: the classic MOC 'fast effect', followed by a gradually increasing suppression, which we call the MOC 'delayed effect'. Delayed suppression typically takes 2-3 minutes to build up, occurs at all frequencies of guinea …

Efficient utilization of Macadamia oil cake based diets in ruminants
… utilization in ruminants. Macadamia Oil Cake (MOC) can be classified among the non-conventional ingredients that can be included in animal diets, without resulting in any negative effects. The present study evaluated the utilization of MOC-based diets in ruminants. Eight Boer and eight Pedi …

Auditory task-dependent control of human cochlear responses to sound
… modulating the effects of medial olivocochlear (MOC) efferent activity in the cochlea. However, conclusive support for this hypothesis has been elusive over the past 50 years. We investigated this issue using a novel experimental paradigm in which human subjects performed auditory tasks on …

The Role of diapycnal mixing in coupled atmosphere-ocean general circulation models
… in the meridional overturning<br/>circulation (MOC). Previous idealised experiments and simplified theory suggest that the strength of<br/>the MOC and the ocean heat transport scale with the v. This study investigates the dependence of<br/>the MOC and other parameters on v using atmosphere-ocean …

Constraining variability of the Atlantic Meridional Overturning Circulation at 25N from historical observations, 1980 to 2005
The Atlantic Meridional Overturning Circulation (MOC) plays an important role in<br/>maintaining western Europe’s moderate climate. Although expected to weaken under<br/>increasing greenhouse gas concentrations, the magnitude of the response remains<br/>uncertain. Monitoring of the Atlantic MOC …

A low order acceleration scheme for solving the neutron transport equation
The Methods of Characteristics (MOC) is a widely used technique for solving partial differential equations, and has been applied to the neutron transport problems for many years. The MOC method requires many transport iterations to solve large heterogeneous LWR reactor problems with high dominance …

Diapycnal mixing transience and the meridional overturning circulation
… of the transience of diapycnal mixing on the MOC. The strength of the MOC was found to be insensitive to mixing transience when mixing occurred uniformly on basin boundaries. For mixing that was highly localized in space, a ten-fold increase in transience, as compared with the time-invariant …

Modulation of cochlear afferent response by the lateral olivocochlear system : activation via electrical stimulation of the inferior colliculus
… inner ear consists of two subdivisions, medial (MOC) and lateral (LOC), with peripheral terminations on outer hair cells and cochlear afferent terminals, respectively. The cochlear effects of electrically activating MOC efferents are well known: the MOC efferents suppress cochlear responses by …

Decadal variability of the subtropical gyre and deep meridional overturning circulation of the Indian Ocean
… of the deep meridional overturning circulation (MOC); and (iii) the influence of diapycnal diffusivity on quasi-steady MOC states.<br/>The decadal variability of the subtropical gyre transport over the ocean interior (away from boundary currents) is investigated using hydrographic data from 32°S. …

Facile Synthesis of High Surface Area Molybdenum Carbide and Nitride: An Application in Support Materials for Oxygen Reduction Reaction
A method to synthesize high surface area α-MoC(1-x) without the temperature programmed reduction (TPR) of MoO3 is described. This method was then used, in conjunction with a novel in situ method to obtain highly dispersed PtMoz supported on α- MoC(1-x), to explore the suitability of such materials …
