Waterloo Farm, Matching Lane, White Roding, Essex. Historic Building Recording (OASIS ID: heritage1-189851)
As the result of an archaeological condition on planning consent for the conversion of a barn at Waterloo Farm, White Roding, the Heritage Network was commissioned to create a record of the building in advance of the works. Documentary evidence has shown that there has been a farmstead on this site since at least the late 16th century. Until the early 19th century this was called Gooses, but the name was probably changed around 1815. The mapping evidence suggests that the present barn forms the remains of a larger cruciform arrangement, shown on the Tithe map of 1840. Between that date and 1874, the farmyard was remodelled and the south-eastern end, below the porches, was either demolished or moved east to form the north-eastern range to the remodelled farmyard. The observed evidence for the barn suggests that is was originally constructed of reused timbers in the early 19th century. Modern renovation works have included the replacement of the timber framing to the south-western gable and to the roof structure, the re-roofing of the midstrey, to form a pent roof rather than the usual gabled roof and the encasing of the sole-plate in concrete and cement

The identification and distribution of an intracellular ciliate in pearl oysters, Pinctada maxima (Jameson 1901)
In October 2001, a new intracellular parasite was detected in Western Australian pearl oysters, Pinctada maxima. This ciliated parasite had not previously been seen in the area despite surveillance over preceding years. A study was performed to identify its characteristics and distribution. The information provided by this study could thereby assist the Pearl Producers Association and Government bodies in determining the industry’s response to infections.
The morphology of the intracellular ciliate of pearl oysters was investigated using light microscopy, revealing organisms that were approximately 5 x 11 μm in size, with 9 rows of cilia and a lobulated nucleus. The ciliates were located within the apical portion of the cytoplasm of digestive epithelial cells of the digestive gland. Investigations into the ultrastructure of the ciliate using transmission electron microscopy (TEM) supported the findings made using histology.
On initial morphological examination, a similarity between the pearl oyster parasite and a ciliate found in Canadian mussels was identified. Samples of Canadian mussels infected with their intracellular ciliate were analysed using light microscopy and TEM. This identified almost identical morphological characteristics to the Western Australian ciliate of pearl oysters, with a slight difference in size that could be attributed to fixation and processing.
The successful culture of adductor muscle, mantle tissue and digestive gland derived cells from pearl oysters was developed and maintained in vitro for up to 75 days, using a number of varying cell culture media. This was attempted in order to provide an ability to study the live intracellular organisms in the laboratory. Contamination and slow growth were the main issues affecting the viability of the technique.
An investigation into the pathology associated with the presence of the ciliate in the pearl oysters was performed. A positive correlation between the presence of the ciliate and an inflammatory response of the digestive gland was displayed using statistical techniques. Pathological changes to the infected cells were demonstrated using TEM, indicating disrupted cytoplasm, vacuolation and nuclear degeneration.
Field trials placing naïve spat in pearl farm leases that had prior ciliate infections were performed. No intracellular ciliates were detected in P. maxima. Other bivalve species from the same regions were examined histologically for health and parasites. With a total of 345 bivalves surveyed during 2005 to 2007, from 8 geographical locations and over 11 species of bivalve included, one oyster contained the intracellular parasite. This oyster was a 20 mm male bastard shell (Pinctada sp.) from Gales Bay, sampled in October 2006. One protozoal parasite was identified in a novel host bivalve species, and a previously undescribed single celled organism was also discovered.
An experimental design for a cross infection trial, should the ciliate become available, was completed. The sensitivity of histology to detect ciliates was also examined, revealing its sensitivity as a diagnostic tool in at risk populations was low (38%) to moderate (50%).
The historical distribution of the ciliate was examined using archival records, indicating that the highest prevalences occurred in the warmer months of October to February from 2001 to 2006. This also corresponded to the months of reduced rainfall.
An attempt at designing a PCR test to determine the molecular characteristics of the ciliate was performed. Formalin fixed, paraffin embedded oyster DNA was successfully extracted, amplified and sequenced, however isolation of ciliate DNA remained elusive, and may have been out-competed with host DNA. In situ hybridisation displayed positive staining with a probe designed from the Ciliophora 16s ssu gene

Vernier hybrid wind turbine generators
A great deal of research is currently being undertaken in the field of renewable energy, much of it dedicated to wind power conversion and focussing on a machine topology that increases efficiency. The vernier hybrid machine, VHM, is one topology considered and has promising features for use in direct drive and variable speed operation. Using the VHM topology, two prototype generators were built and tested. The machines use magnets that are buried within the stator and orientated in a flux concentration arrangement. The flux paths in the machines are inherently 3D in nature and thus require complicated modelling methods to achieve sufficient design accuracy. Various tests were conducted in an effort to find results that will describe the machines characteristics and operating mechanisms. It was found that increased torque handling capabilities can be observed at the detriment of power factor and construction complexity. With the use of power factor correction and suitable construction techniques the VHM is a viable wind turbine generation technique. To determine whether it is suitable for renewable energy applications would require an in depth economic feasibility study over the operating lifetime of the machine

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
Abstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
