No full text5 Photographs published within the first book from Matt O'Connor, a freelance marketing consultant and family law campaigner. This is Matt O'Connor's personal account of the most controversial protest movement of recent times, FATHERS 4 JUSTICE. Fearlessly honest and utterly irreverent Matt's own story will appeal to anyone whose family relationships have been torn to pieces by divorce and the family courts system
HIGH-ENERGY PHENOMENA STUDIED WITH X-RAY POLARIMETRY
No full textAfter more than 30 years since the last X-ray polarimetric measurements, performed in the 70's by the OSO-8 satellite, thanks to recent technological advances, polarimetry is considered again as a viable technique for studing X-ray sources. In this contribution the author briefly discusses a couple of astrophysical situations, related to the topics of this conference, where X-ray polarimetry can be extremely useful. The author also discusses the observational perspectives, listing the main future space missions (proposed or even already approved) carrying on-board an X-ray polarimeter
The XMM-Newton long look of NGC 1365: uncovering of the obscured X-ray source
No full textWe present an analysis of the extreme obscuration variability observed during an XMM–Newton 5-d continuous monitoring of the active galactic nuclei (AGN) in NGC 1365. The source was in a reflection-dominated state in the first ∼1.5 d, then a strong increase in the 7–10 keV emission was observed in ∼10 h, followed by a symmetric decrease. The spectral analysis of the different states clearly shows that this variation is due to an uncovering of the X-ray source. From this observation, we estimate a size of the X-ray source DS < 1013 cm, a distance of the obscuring clouds R∼ 1016 cm and a density n∼ 1011 cm−3. These values suggest that the X-ray absorption/reflection originates from the broad-line region clouds. This is also supported by the resolved width of the iron narrow Kα emission line, consistent with the width of the broad Hβ line

The importance of cholesterol in MAP infection of ruminants
No full textCholesterol plays an important role in the establishment of mycobacterial infections. Mycobacterial species such as Mycoacterium tuberculosis are capable of utilising cholesterol as a primary energy source in culture. M. leprae localises to cholesterol-rich areas of an infected cell, which holds significance for the intracellular niches created by mycobacteria.
Despite the implications for other mycobacterial species, there has been very little research examining the relationship between cholesterol and Mycobacterium avium subsp. paratuberculosis (MAP). This study examined the role of both serum and intracellular cholesterol during the early stages of MAP infection in both sheep and cattle in vivo and in vitro.
Using a well-established infection model, sheep and cattle were exposed to MAP and blood and faecal samples were collected at monthly intervals. Total serum cholesterol changed significantly in exposed animals during the first few months of infection in both sheep and cattle when compared to the control cohorts. In in vitro infection experiments using monocytes from MAP non-exposed cattle and sheep and fluorescent microscopic techniques demonstrated that GFP-tagged MAP co-localised to cholesterol-rich domains within the cell. In addition, changes in the expression of a number of cholesterol-associated genes within the macrophage suggest that MAP is capable of altering cholesterol metabolism of the infected cell. Thus previously unexplored mechanisms within the intracellular environment created by MAP during the early stages of infection may be important for understanding the survival and persistence of MAP

[email protected] The State of Maine is known to have a population of residents that are highly active in outdoor recreation activities and regularly visit Maine’s State Parks. Even though residents’ overall constraints to participating in outdoor recreation in Maine were found to be relatively low, a considerable portion of the population experiences significant barriers for participating in recreational activities while other analogous factors further constrain these residents from visiting Maine State Parks. For this study, a survey was conducted with a sample of Maine residents who were each asked to indicate the factors that limit their pursuit of outdoor recreational activities in general as well as specify, from a corresponding list of limitations, why they had not visited a Maine State Park before (n=399). The results of McNemar chi-square analyses found that being too busy, lack of knowledge, lack of interest, and family status were statistically significant overlapping constraints (p<0.05)
Long-term wind-driven X-ray spectral variability of NGC 1365 with Swift
No full textWe present long-term (months–years) X-ray spectral variability of the Seyfert 1.8 galaxy NGC 1365 as observed by Swift, which provides well-sampled observations over a much longer time-scale (six years) and a much larger flux range than is afforded by other observatories. At very low luminosities, the spectrum is very soft, becoming rapidly harder as the luminosity increases and then, above a particular luminosity, softening again. At a given flux level, the scatter in hardness ratio is not very large, meaning that the spectral shape is largely determined by the luminosity. The spectra were therefore summed in luminosity bins and fitted with a variety of models. The best-fitting model consists of two power laws, one unabsorbed and another, more luminous, which is absorbed. In this model, we find a range of intrinsic 0.5–10.0 keV luminosities of approximately 1.1–3.5 erg s?1, and a very large range of absorbing columns, of approximately 1022–1024 cm?2. Interestingly, we find that the absorbing column decreases with increasing luminosity, but that this result is not due to changes in ionization. We suggest that these observations might be interpreted in terms of a wind model in which the launch radius varies as a function of ionizing flux and disc temperature and therefore moves out with increasing accretion rate, i.e. increasing X-ray luminosity. Thus, depending on the inclination angle of the disc relative to the observer, the absorbing column may decrease as the accretion rate goes up. The weaker, unabsorbed, component may be a scattered component from the wind
PROSTHETIST KNOWLEDGE AND 3D PRINTING
No full textIn this paper we briefly explored the history of 3D printing in prosthetics. We provided details of our own work developing 3D printing design tools from 2014-2020 noting how claims around prosthetist experience and knowledge have been supported and/or questioned in the development of new device production techniques. We ended by arguing for deeper attention to prosthetist knowledge and experience in the design of the growing 3D printing ecosystem, seeing this focus as necessary and important to preserve and support clinical prosthetist in the production of well-fitting and appropriate devices for patients.
