Handbook of Accounting and Development
No full text'Trevor Hopper and his colleagues provide a central point of reference for research into accounting and development. Definitive chapters from internationally recognised authors (including Marcia Annisette, Kerry Jacobs, Chris Poullaos, Brendan O'Dwyer, Chibuike Uche and Jeffrey Unerman) cover the full range of issues from the role of capital markets in development, through accounting professionalization, to taxation and transfer pricing. Contributions from authors working for donors and non-governmental organisations provide a useful practical dimension that builds on the more academic chapters.' - Christopher Napier, Royal Holloway, University of London, UK. © Trevor Hopper, Mathew Tsamenyi, Shahzad Uddin and Danture Wickramasinghe 2012.

Edward Hopper. Le passioni dell’intervallo
No full textUn'analisi semiotica dell’opera di Edward Hopper, alla ricerca della dimensione narrativa dello spazio dipinto. Il lavoro esce dal luogo comune che vorrebbe Hopper pittore della solitudine per rileggerlo alla luce del tema dell’Annunciazione, motivo della pittura occidentale, una Annunciazione laica e vicina al sentire dell’uomo del secolo scors

Lithospheric controls on melt production during continental breakup at slow rates of extension: Application to the North Atlantic
No full textRifted margins form from extension and breakup of the continentallithosphere. If this extension is coeval with a region of hotter lithosphere,then it is generally assumed that a volcanic margin would follow. Herewe present the results of numerical simulations of rift margin evolution byextending continental lithosphere above a thermal anomaly. We find that unlessthe lithosphere is thinned prior to the arrival of the thermal anomalyor half spreading rates are more than ? 50mmyr?1, the lithosphere actsas a lid to the hot material. The thermal anomaly cools significantly by conductionbefore having an effect on decompression melt production. If the lithosphereis thinned by the formation of extensional basins then the thermalanomaly advects into the thinned region and leads to enhanced decompressionmelting. In the North Atlantic a series of extensional basins off the coastof northwest Europe and Greenland provide the required thinning. This observationsuggests that volcanic margins that show slow rates of extension,only occur where there is the combination of a thermal anomaly and previousregional thinning of the lithosphere
MODELING OF HOPPER DISCHARGE
No full textHoppers are widely used in many engineering processes. The discharging of granular mate- rials from a hopper is a critical topic of industrial importance, and the discharge flow rate from hoppers is the focus of the current work. Many parameters influence the discharge rate including: the hopper outlet width, the angle of the hopper wall, the particle size, and particle friction, and so on. Due to the expensive of examining a large variety of particle types and hopper conditions, computational simulation has been widely studied in an effort to establish an alternative method of determining critical factors impacting hopper flow.
In this thesis, the process of hopper discharge has been simulated by the Discrete Element Method (DEM), which is one of the most popular methods for granular flow simulation. To validate against existing experiments, all conditions were matched as closely as possible to those in the experiment. The particles used in our simulation are spheroids with diameters of 0.77 cm. The angles of the hoppers examined range from 0◦ to 90◦, while the opening sizes vary from 2.9 cm to 4.3 cm. Computationally, the friction coefficient has been adjusted several times and finally is set to 0.5 in the simulation in order to fit the experimental resultsas closely as possible. As a quantitative test of the simulation fidelity we compare the hopper empty time t – which is related to the hopper discharge rate – for these different hopper angles and hopper opening size. As a secondary test of the fit, the survival time τ, the normal force profile, the velocity profile, and the probability of jamming Ps are also computed and compared to existing experimental data from collaborators at Duke University. Ultimately, the goal of the work is to establish the degree of model fidelity necessary in order to closely mimic the experimental results obtained

Structural validation of oral mucosal tissue using optical coherence tomography
No full textBackground:
Optical coherence tomography (OCT) is a non-invasive optical technology using near-infrared light to produce cross-sectional tissue images with lateral resolution.
Objectives:
The overall aims of this study was to generate a bank of normative and pathological OCT data of the oral tissues to allow identification of cellular structures of normal and pathological processes with the aim to create a diagnostic algorithm which can be used in the early detection of oral disorders.
Material and methods:
Seventy-three patients with 78 suspicious oral lesions were referred for further management to the UCLH Head and Neck Centre, London. The entire cohort had their lesions surgically biopsied (incisional or excisional). The immediate ex vivo phase involved scanning the specimens using optical coherence tomography. The specimens were then processed by a histopathologist.
Five tissue structures were evaluated as part of this study, including: keratin cell layer, epithelial layer, basement membrane, lamina propria and other microanatomical structures. Two independent assessors (clinician and pathologist trained to use OCT) assessed the OCT images and were asked to comment on the cellular structures and changes involving the five tissue structures in non-blind fashion.
Results:
Correct identification of the keratin cell layer and its structural changes was achieved in 87% of the cohort; for the epithelial layer it reached 93.5%, and 94% for the basement membrane. Microanatomical structures identification was 64% for blood vessels, 58% for salivary gland ducts and 89% for rete pegs. The agreement was “good” between the clinician and the pathologist.
OCT was able to differential normal from pathological tissue and pathological tissue of different entities in this immediate ex vivo study. Unfortunately, OCT provided inadequate cellular and subcellular information to enable the grading of oral premalignant disorders.
Conclusion:
This study enabled the creation of OCT bank of normal and pathological oral tissues. The pathological changes identified using OCT enabled differentiation between normal and pathological tissues, and identification of different tissue pathologies.
Further studies are required to assess the accuracy of OCT in identification of various pathological processes involving the oral tissues
