Mössbauer time-reversal studies
We have investigated Mössbauer time-reversal experiments, in an attempt to lower the upper limit on the time reversal violating part of the mixed electromagnetic=hadronic Hamiltonian. We were unsuccessful in the search for experimental conditions which would have permitted lowering the limit by a …

Magnesium recurarisation differences between no reversal, neostigmine/glycopyrrolate reversal and sugammadex reversal of neuromuscular block in an in vivo rat model
… fear of recurarisation. Recurarisation following reversal of neuromuscular blockade with neostigmine or sugammadex has not been evaluated in a formal study, and for this reason, this study investigated recurarisation after 30 mg/kg magnesium sulphate (MgSO4) following reversal of neuromuscular …

Motion-reversal in colloidal walkers
In this research, the manipulation of colloidal systems composed of superparamagnetic particles in water is studied by a simulation method. In response to an external magnetic field, the dipoles drive the beads to self-assemble into chains, which rotate and consequently move across a nearby …

Ádám's Conjecture and Arc Reversal Problems
… digraph <em>D</em>, there exists an arc whose reversal reduces the total number of cycles in <em>D</em>. In this thesis we characterize and identify structure common to all digraphs for which Ádám's conjecture holds. We investigate quasi-acyclic digraphs and verify that Ádám's conjecture holds …

Magnetisation reversal in permanent magnet materials
This thesis presents an investigation of the reversal of magnetisation in sintered anisotropic Nd-Fe-B, isotropic melt-spun Nd-Fe-B powder, and in Sm-(Co,Cu,Fe,Zr) 2:17 anisotropic powder. Magnetisation measurements have been performed using vibrating sample magnetometers, a permeameter, and an …

Estimating the probability of loss reversal
This study aims to examine loss reversals with an emphasis on the effect of research and development expenditures on the probability of experiencing loss reversals. This paper builds on previous research by examining a variety of company variables such as accruals, cashflows, dividends, company …

Magnetic reversal of artificial spin ice
… studies that center around the magnetic reversal of artificial spin ice arrays. First, I investigate the magnetic response of permalloy brickwork artificial spin ice. Through the systematic study of the transport properties for finely varied magnetic field directions, I find that the …

Puncture Reversal of Polyethylene Ionomers - Mechanistic Studies
Ionomers are polymers that contain ionic groups in relatively low concentrations along the polymer backbone. These ionic groups, in the presence of oppositely charged ions, form aggregates that lead to novel physical properties of the polymer. React-A-Seal® and Surlyn® are …

MAGNETISATION REVERSAL STUDIES OF PARTICULATE RECORDING MEDIA.
… media and a numerical investigation of the reversal mechanism of particles within the media have been made. The particle systems investigated comprised three audio y-Fe203 tapes, three audio Cr02 tapes and a video metal particle tape. An absolute measure of the interaction effects within …

Reversal of Polarity In Some Woody Dicotyledonous Angiosperms
… only. According to theory – in case of the reversal of the position of these ends in relation to moisture, a corresponding reversal in type of plant organ produced will not ensue and persist. The experiment under discussion in this paper was carried out in an endeavor to determine the …

Rank reversal properties of multicriteria decision making models
… two models, and some examples which shows rank reversal caused by this new alternative could be harmful. As a continuous thinking of this case, in the second part, detailed proof are given about a method from Dr. S. Z. Nemeth, by defining the ’maximal box’ in avoid causing rank reversal. These …

Trend Reversal in Lake Michigan Contribution to Snowfall
… the early 2000s indicating a distinct trend reversal not reported by earlier studies. The reasons for this reversal are unclear. However, LCS trend reversal is consistent with observed increasing minimum temperatures during winter months after the 1970s. LCS and minimum temperature trends are …

Magnesium sulphate reversal of established bupivacaine electrophysiological cardiotoxicity
The results of this study show that in intact rats magnesium produces a more rapid resolution of bupivacaine induced electrophysiological changes than placebo. The improvements are in rhythm and electrical conduction, although this is often at the expense of potentiating the bradycardic effects of …

Reversal of Neurodegeneration By Engineered Monocytes In Alzheimer’S Disease
<p>The health challenges posed by Alzheimer’s disease (AD) continue to grow as societies age worldwide. Accumulation of Tau-associated pathology correlates with clinical cognitive deterioration in AD. Resident myeloid cells within the central nervous system (CNS) have a limited capacity to uptake …
