- Abstract
The Paleogene outlier at Collier's End, Hertfordshire lies on the northern rim of the London Basin. This small outlier has archaeological and geological significance. Silica-cemented concretions of Hertfordshire Puddingstone lie within a regionally mappable pebble bed. The first discovery of a Roman quarry to recover puddingstone for manufacture of querns was made in the outlier. A rare complete section from the Chalk Group up through the Paleogene was temporarily exposed in 2021 and is recorded here. The Paleogene shows features that may be associated with the Paleocene–Eocene Thermal Maximum (PETM). The chalk in the new exposure is Late Coniacian. This age provides further evidence of relatively deep erosion of the chalk in this area, as erosion of chalk at the crest of a regional dome preceded advances and retreats of the western shore of the Paleogene North Sea. These events may be linked to the early development of the Icelandic mantle plume. [ABSTRACT FROM AUTHOR]

Jones, Mervyn and Green, Chris
- Abstract
A 10.5 Ha site within three lobes of ancient woodland on the Gaddesden Estate, West Hertfordshire, was investigated using geological and archaeological techniques. 2–3 m of Paleogene silt-sand and gravel drapes the Chalk. Discontinuous lenses of pebbly conglomerate have been silicified to create concretions of Hertfordshire Puddingstone [HPS hereafter], one of which was in situ , a very rare find. The HPS is associated with a pure white sand and a previously un-reported lithology, a soft white pebbly Sarsen. During the Quaternary the feather edge of the Cenozoic cover was punctured following underlying dissolution features in the chalk to create 93 dolines, the largest concentration in the Chilterns AONB. As they grew the dolines were filled with Pleistocene loessic brickearth during the Wolstonian stage (MIS7) and captured blocks of HPS. These were exploited by the Romans as valuable raw material for quern-making. Shortly after the Roman Conquest in AD43 the site was cleared by felling and burning the tree cover. The cortex and poor-quality core stone were cut away from concretions with picks, manageable slices were detached using steel wedges and initial shaping was undertaken to produce blanks of querns to be finished elsewhere. Quarrying continued for, at most, fifty years. The excavated doline fills or upcast formed rims around the pits, which taken together protect the second largest remaining area of Roman ground surface in Hertfordshire. The site was abandoned and has been largely undisturbed apart from some quarrying of chalk and brickearth and offers further opportunities for research. [ABSTRACT FROM AUTHOR]

GREEN, CHRIS
- Abstract
MAY 26, 2023 Recently, Jonathan Cook published a piece in Consortium News defending Glenn Greenwald and Russell Brand from claims that the two have been pandering to the far right by appearing on the now former Tucker Carlson Tonight program on Fox News and other right-wing media outlets. Anyway, the following month, Greenwald said this: "I think people have forgotten just how radical Trump's administration could have been if he had followed through on the populist politics of those advising him. But that was what Trump ran on and that was the plan " It is touching to think that Greenwald really believes that the economic populist noises emanating from Trump's 2016 campaign were really "the plan" for his administration- until Jared Kushner proved better at factional infighting that Steve Bannon.

- Abstract
Direct geological information in Antarctica is limited to ice free regions along the coast, high mountain ranges, or isolated nunataks. Therefore, indirect methods are required to reveal subglacial geology and heterogeneities in crustal properties, which are critical steps toward interpreting geological history. We present a 3D crustal model of density and susceptibility distribution in the Wilkes Subglacial Basin (WSB) and the Transantarctic Mountains (TAM) based on joint inversion of airborne gravity and magnetic data. The applied “variation of information” technique enforces a coupling between inferred susceptibility and density, relating these quantities to the same gravity and magnetic sources to give an enhanced inversion result. Our model reveals a large body located in the interior of the WSB interpreted as a batholithic intrusive structure, as well as a linear dense body at the margin of the Terre Adélie Craton. Density and susceptibility relationships are used to inform the interpretation of petrophysical properties and the reconstruction of the origin of those crustal bodies. The petrophysical relationship indicates that the postulated batholitic intrusion is granitic, but independent from the Granite Harbor Igneous Complex described previously in the TAM area. Emplacement of a large volume of intrusive granites can potentially elevate local geothermal heat flow significantly. Finally, we present a new conceptual tectonic model based on the inversion results, which includes development of a passive continental margin with seaward dipping basalt horizons and magmatic underplating followed by two distinct intrusive events associated with the protracted Ross Orogen. Most rocks in Antarctica are hidden beneath a thick ice sheet. Therefore, indirect techniques are required to reveal rock provinces within Earth's crust below the ice. Rocks simultaneously influence the gravity and magnetic fields through their physical properties (density and susceptibility). Here we use both the gravity and magnetic fields to reveal rock provinces beneath the ice and use the relationship between density and susceptibility of the rocks to interpret the distribution of granitic rocks of the Transantarctic Mountains and the Wilkes Subglacial Basin region in East Antarctica. Granitic rocks can lead to elevated heat flow due to radiogenic decay of minerals within the rock and thus influence the overlying ice sheet. Based on our subsurface model of rock provinces we speculate on the tectonic evolution of the region. We present a new 3D crustal density and susceptibility distribution model based on joint inversion of gravity and magnetic dataDensity and susceptibility data are used to identify crustal level intrusions and the craton marginOur new conceptual tectonic model identifies a earlier intrusive event in the interior of the Wilkes Subglacial Basin, separate from those exposed in the Transantarctic Mountains We present a new 3D crustal density and susceptibility distribution model based on joint inversion of gravity and magnetic data Density and susceptibility data are used to identify crustal level intrusions and the craton margin Our new conceptual tectonic model identifies a earlier intrusive event in the interior of the Wilkes Subglacial Basin, separate from those exposed in the Transantarctic Mountains

6. Intrapersonal mindfulness is associated with reduced risk of burnout among Central Appalachian educators.

Anama-Green, Chris
- Abstract
Background: National statistics suggest that up to 40% of new teachers will leave their school or the teaching profession within their first five years of teaching. Much of this attrition is associated with work-related burnout, some of which may be preventable with targeted worksite health interventions. Previous research suggests that mindfulness skills may be protective from burnout, ultimately reducing the likelihood of attrition from the profession.Methods: This study compared the self-reported levels of burnout and secondary traumatic stress with participants' levels of interpersonal and intrapersonal mindfulness. A total of 144 participants completed the Professional Quality of Life Inventory and the Mindfulness in Teaching Inventory. Study participants included K-12 teachers in Eastern Kentucky. Odds Ratios and Relative Risks were calculated using Epi Info. Pearson correlations, linear regression, and ANOVA analyses were completed using SPSS. Chronbach's alpha values were also calculated to evaluate score reliability of the five constructs.Results: Relative Risks and Odds Ratios of having secondary traumatic stress scores of "average/high" were significantly lower for those with high intrapersonal mindfulness scores (OR = 0.12, CI: 0.05-0.30; RR = 0.21, CI: 0.10-0.44). Those who reported high intrapersonal mindfulness scores were up to 11 times more likely to report "low" burnout than those who reported low intrapersonal mindfulness scores (OR = 11.58, CI: 5.06-26.52). Burnout neg- atively correlated with intrapersonal mindfulness (r = -0.616, p < .05) suggesting that as intrapersonal mindfulness level decreases, burnout increases. ANOVA testing identified significant differences in burnout based on intrapersonal mindfulness level (F = 8.928, p <.05).Conclusion: Those who reported high levels of intrapersonal mindfulness had significantly reduced risk of burnout. These results will inform further research in the region regarding mindfulness practice and the experience of burnout among teachers in the region. Thus, mindfulness may be protective from occupation-related burnout for this population. Interventions informed by additional research could reduce the burden of occupation-related burnout and may ultimately contribute toward reduced attrition in the teaching profession.

8. Suitability of depleted gas fields for underground hydrogen storage in Australia

Michael, Karsten, Ennis-King, Jonathan, Strand, Julian, Sander, Regina, and Green, Chris
- Abstract
If there is a significant adoption of hydrogen in Australia as an energy carrier, it will be necessary to have storage options to buffer the fluctuations in supply and demand, both for domestic use and for export. For large-scale storage in a single location, underground hydrogen storage (UHS) is the preferred option for reasons of both cost and safety. The search for suitable sites for UHS will depend on the proximity to potential hydrogen generation, ports, and processing infrastructure, as well as CO2 storage options for blue hydrogen. Although UHS in salt caverns is an established technology, most of the suitable salt deposits in Australia (in the Canning Basin in WA, the Adavale Basin in Qld, and the Amadeus Basin in the NT) are not always well-located for production and transport. Depleted gas fields have been used previously for storage of hydrogen-rich gas mixtures as well as natural gas storage and appear to be the most promising and widely available UHS option in Australia. There appears to be sufficient storage capacity in depleted gas fields in most of the geographic areas with hydrogen production potential. However, there are still technical challenges to be addressed, such as the extent of possible contamination of the stored hydrogen with residual hydrocarbons, and the possible effects of geochemical reactions and microbial processes.

Green, Chris E. W.
- Abstract
ABSTRACTTerrence Malick’s A Hidden Life(2019) not only tells the story of Franz Jägerstätter but also depicts Malick’s deeply Catholic understanding of art and the artist’s vocation, an understanding that portrays art, and in particular art that seeks to witness to the truth Jesus Christ embodies, as a kind of costly obedience. The author explores Malick’s Catholic vision of art and its implications for Pentecostal ministry.

Johnson, Lance, Liette, Michael D., Green, Chris, Rodriguez, Pedro, and Masadeh, Suhail
- Abstract
The reverse sural artery flap is a distally based fasciocutaneous or adipofascial flap used for wound coverage of the distal one-third of the lower extremity, ankle, and posterior heel. The flap harvest can be performed without sacrificing major arteries of the lower extremity. It can be elevated and mobilized with relative ease and a short operative time. It provides a good alternative to free tissue transfer in complex lower-extremity wounds with exposed bone, tendon, or hardware. The surgeon must be familiar with the management of venous congestion to improve the success of the flap.

Paul, Julia A., Chateau, Joanne, Green, Chris, Warda, Lynne, Heaman, Maureen, Katz, Alan, Perchuk, Carolyn, Larocque, Lorraine, Lee, Janelle Boram, and Nickel, Nathan C.
- Abstract
Objective: The Manitoba Infant Feeding Database (MIFD) is being piloted as a surveillance system leveraging infant vaccination visits as a point of contact to collect infant feeding data during the first year of life. The objective of this study was to assess data quality and acceptability of the MIFD as a sustainable population-based surveillance system. Methods: Internal completeness and internal validity were measured to assess data quality. Internal completeness was defined as the number of completed data fields out of the total number of data fields. Internal validity was defined as the proportion of translation errors from one level of the system, the paper questionnaire, to the next, the electronic database. A survey assessed staff’s acceptance of data collection and submission processes. Results: A total of 947 records were reviewed. Data were 98.5% complete. Discrepancies were noted in 13.5% of data. The survey response rate was 78.4%. Nearly all respondents reported that the MIFD data collection tool was easy to use (96.6% agreed or strongly agreed). Whereas some challenges were identified, the majority were willing to continue with the MIFD data collection tool and process (93.1%). Conclusion: Results from this evaluation suggest that the MIFD data collection process worked well; however, data validation will require human resources. The MIFD approach provides a sustainable mechanism for collecting data on infant feeding for surveillance and research purposes.

13. Egg Production of Gulf Killifish Is Dependent on Broodstock Rearing Density but Not Spawning Substrate Surface Area

Chesser, Brittany M., Green, Chris C., and Allen, Peter J.
- Abstract
The Gulf Killifish Fundulus grandisis a popular baitfish for recreational fisheries and is a candidate for commercial‐scale culture; however, its relatively low fecundity compared to other baitfish presents a production challenge. Egg output in relation to broodstock densities and spawning mat surface areas was evaluated in recirculating aquaculture systems (RASs). In experiment 1, broodstock were stocked at two densities (45 and 90 fish/m³), with eggs collected three times per week for 8 weeks. Broodstock (15–17 g) that were held at 45 fish/m³ had greater reproductive output (3.93 eggs·female−1·d−1) than broodstock that were held at 90 fish/m³ (2.22 eggs·female−1·d−1). However, there was no difference between the number of eggs per collection (1,005 and 1,107 eggs per 3,600‐L tank) or total egg production (23,202 and 25,802 eggs per 3,600‐L tank), indicating that reproductive output was limited by another factor, such as available spawning substrate. Therefore, in experiment 2, broodstock (12–16 g) were stocked at a density of 100 fish/m³ in all tanks and were held for 8 weeks with one of three spawning mat (Spawntex) surface areas: 4,500 cm2(one tier), 9,000 cm2(two tiers), or 13,500 cm2(three tiers). Reproductive output was 2.12, 2.27, and 2.21 eggs·female−1·d−1for the one‐tier, two‐tier, and three‐tier treatments, respectively, with no differences among treatments. There was also no among‐treatment difference in the number of eggs per collection (1,724, 1,858, and 1,794 eggs/tank) or in the total number of eggs collected (27,587, 29,728, and 28,704 eggs/tank), suggesting that increasing the surface area of spawning material does not increase egg production. Therefore, a stocking density of 45 fish/m³ and a spawning mat surface area of 4,500 cm2in commercial‐scale RASbroodstock tanks result in similar egg production compared to a higher stocking density and greater spawning mat surface area.

15. Simulation of CO2 Migration for the Planning of Well Test Configurations at the South West Hub Project, Western Australia.

Green, Chris, Michael, Karsten, and Paterson, Lincoln
- Abstract
Containment of injected CO 2 at the South West Hub project in Western Australia is dependent on non-structural trapping mechanisms in the 1500 m thick Wonnerup Member of the Lesueur Sandstone due to uncertainties regarding the sealing character of the ∼600 m thick overlying Yalgorup Member. Therefore, vertical migration distance and sweep efficiency and their impact on residual saturation and CO 2 dissolution need to be properly assessed through reservoir simulations. We find that conventional Darcy-flow reservoir simulations result in significantly different predictions of plume migration compared to invasion percolation modelling when injecting at the base of the Wonnerup Member. If numerical predictions of the fate of injected CO 2 are sensitive to the choice of model, care must be taken when selecting the methodology. One way to validate simulation predictions at a scale appropriate to the modelling is the use of well tests. In the Wonnerup Member a vertical migration test is recommended for consideration to confirm whether conventional reservoir simulations or percolation invasion modelling accurately predict the CO 2 migration processes at the site. This test would involve a small injection of CO 2 that is allowed to migrate upwards. The migration would be monitored with repeat pulsed neutron logging. This represents a new kind of test unique to the situation for the South West Hub site. [ABSTRACT FROM AUTHOR]

- Abstract
Variation in the density of archaeological evidence is caused by a multitude of interacting factors, some of which reinforce each other and some of which act to disguise genuine patterns of past practice. This paper initially presents a set of density models for England constructed by the members of the English Landscape and Identities (EngLaId) project and then goes on to discuss three possible explanations for the variation seen: modern affordance, variability in past usage of material culture, and past population density. The various members of the project team (with the aid of Andrew Lowerre) then provide their thoughts on the models and ideas presented from their own specific period specialist perspectives. The article is presented in this discursive format to reflect the differing opinions and approaches across an unusual multi-period project, in the spirit of multi-vocality and healthy debate.

Burger, Wesley S., Ramee, Shane W., Culpepper, Charlie M., Green, Chris C., and Allen, Peter J.
- Abstract
The Gulf Killifish Fundulus grandis, a popular baitfish species inhabiting estuaries in the northern Gulf of Mexico, has potential as an aquaculture species, particularly if it can be produced in low‐salinity or freshwater ponds. Because growth and survival in freshwater ponds are not known, two size‐classes were examined over a 16‐week period. Initial mean stocking weights and densities were 0.47 g/fish and 26,500 fish/ha for the smaller size‐group, which was stocked into three 0.04‐ha ponds, and 6.12 g/fish and 20,450 fish/ha for the larger size‐group, which was stocked into two 0.04‐ha ponds. Growth and survival were similar between size‐classes: mean final weight and mean survival were 7.88 g/fish and 54.3%, respectively, for the smaller size‐group, and 13.90 g/fish and 43.1% for the larger size‐group. Mean weight gain was very similar between size‐groups (small: 7.41 g; large: 7.78 g); steady growth was observed from June until mid‐September, whereas little growth and declines in condition factor were observed from mid‐September to mid‐October, corresponding with decreases in water temperature. Gulf Killifish were resilient to a wide range of water quality conditions in freshwater ponds and reached market sizes of 3 g at about 4 weeks and 5 g by 8 weeks.

- Abstract
The discovery of a Roman quarry for recovery of Hertfordshire Puddingstone was first reported by Lovell and Tubb (2006) , from the Colliers End Paleogene outlier in the east of the county. Hundreds of querns are known to have been manufactured from the distinctive pebbly siliceous concretions renowned as Hertfordshire Puddingstone. The existence of further sources of the raw material has been obvious ( Green, 2016 ), but quarries have proved elusive, and surface extraction from isolated boulders has been a possibility. However a further concentration of Roman pits has now been discovered in the west of the county, in the Paleogene outlier at Great Gaddesden. The evidence for quarrying is introduced in a regional geological and archaeological context. Plans for more detailed work are summarised. [ABSTRACT FROM AUTHOR]

Green, Chris
- Abstract
The use of sarsen and puddingstone in England and Normandy since the Bronze Age is briefly reviewed (for sarsen), and described following fieldwork and museum research (for puddingstone). The rock sources of puddingstone/ poudingue querns [hand-mills] are located and characterised, and the distribution of the products shown. The current distribution of Hertfordshire Puddingstone is shown, reflecting periglacial movement and human clearance. The production process is outlined for the main agency involved, the Romano-British puddingstone quern industry (AD 50–150). Sarsen-cutting, particularly in Wiltshire and Buckinghamshire between 1850 and 1939, provides a parallel case of clearance of boulders from the landscape. Industrial exploitation is shown to have radically altered the ‘natural’ distribution of silcretes in England and northern France. [ABSTRACT FROM AUTHOR]

An enthusiasm for vastly inflated US military budgets is what unites Trump, Greene and Gaetz, heterodox critics of establishment US foreign policy (at least according to Greenwald's imagination). Indeed, other MAGA politicians recently praised by Greenwald for opposition to US support for Ukraine (Trump, Matt Gaetz) also share the Confrontation-with-China-instead-of-Russia approach to US foreign policy. Glenn Greenwald, along with his buddy Matt Taibbi, is currently the most prominent ideological turncoat emanating from the American left. [Extracted from the article]

32. Anomalously High Heat Flow Regions Beneath the Transantarctic Mountains and Wilkes Subglacial Basin in East Antarctica Inferred From Curie Depth

Lowe, Maximilian, Mather, Ben, Green, Chris, Jordan, Tom A., Ebbing, Jörg, and Larter, Robert
- Abstract
The Transantarctic Mountains (TAMs) separate the warmer lithosphere of the Cretaceous‐Tertiary West Antarctic rift system and the colder and older provinces of East Antarctica. Low velocity zones beneath the TAM imaged in recent seismological studies have been interpreted as warm low‐density mantle material, suggesting a strong contribution of thermal support to the uplift of the TAM. We present new Curie Point Depth (CPD) and geothermal heat flow (GHF) maps of the northern TAM and adjacent Wilkes Subglacial Basin (WSB) based exclusively on high resolution magnetic airborne measurements. We find shallow CPD and high GHF beneath the northern TAM, reinforcing the hypothesis of thermal support of the topography of the mountain range. Additionally, this study demonstrates, that limiting spectral analysis to areas with a high density of aeromagnetic measurements increases the resolution of CPD estimates revealing localized shallow CPD and associated high heat flow in the Central Basin of the WSB and the Rennick Graben (RG). Across the study area the CPD ranges from 15 to 35 km and the GHF values range from 30 to 110 mW/m2. The recovered CPD range is compatible with recent Moho depth estimates, as the CPD predominantly lies within the crust, rather than in the magnetite‐poor mantle. GHF estimates, based on the CPD estimates, show a good agreement to sparse in situ GHF measurements and the location of active volcanoes. Comparison to existing continent‐wide GHF estimates shows strong differences from magnetically‐derived heat flow estimates, while seismologically‐derived heat flow estimates show the best agreement to our results. The Transantarctic Mountains (TAMs) separating the ancient East Antarctic region from the younger West Antarctic region. Recent studies found regions where acoustic waves move slowly beneath the TAM. Slow wave speeds are considered to be caused by warmer rocks at depth, which provide thermal support for the TAM. We present heat flow maps for this region. The estimated heat flow is based on “Curie Point Depths” (CPDs), which describes the depth at which magnetic rocks lose their magnetic properties due to increasing temperature. This temperature is called the Curie temperature (∼580°C for magnetite, the most common magnetic mineral in the Earth's crust). The heat flow at the surface is estimated from the depth at which this temperature is reached. We use for the first time for a CPD study in Antarctica exclusively high‐resolution magnetic data measured from aircraft. We demonstrated that limiting this method to airborne data improves the resolution of CPD variation, and thus heat flow estimates, substantially. We find shallow CPD and high heat flow beneath the TAM, which supports the suggestion that warmer rocks provide thermal support for the TAM. Additionally, we find high heat flow in the adjacent Wilkes Subglacial Basin and Rennick Graben.

We have developed a simple iterative gravity-inversion approach to map the basement and Moho surfaces of a rift basin simultaneously. Gravity anomalies in rift basins commonly consist of interfering broad, positive crustal-thinning anomalies and narrow, negative sedimentary-basin anomalies. In our model, we assumed that the Moho and basement surfaces are in Airy isostatic equilibrium. An initial plane-layered model was iterated to fit the gravity data. We applied the process to a model in which the inverted basement and Moho surfaces matched the model surfaces well and to a gravity profile across the Kosti Basin in Sudan. [ABSTRACT FROM AUTHOR]

We sought to map the depth and density contrast of the Mohorovicic discontinuity (Moho) across the Red Sea area and to model sedimentary thickness from gravity data. The gravity data that are used are a combination of satellite and terrestrial gravity data processed into a Bouguer anomaly grid. A 200-km low-pass filter was used to separate this grid into regional and residual gravity grids. We inverted the regional gravity grid to a Moho depth map based on a density contrast map that is constrained by published seismic results. The interpreted Moho is shallowest (<10 km) along the axis of the central Red Sea, ~13 km along the axis to the south, and ~20 km in the northern Red Sea. The depth increased to ~20-25 km at the coast and 35-40 km in the adjacent continents. The residual gravity data provided insights into the tectonic fabric along the whole rift and provided a good correlation with magnetic lineaments where these are available. We used the complete Bouguer anomaly to model sedimentary thicknesses constrained by wells and the interpreted Moho. The modeling results are consistent with the presence of largescale, ridge parallel tilted fault blocks forming subbasins with a maximum depth of about 6-7 km. Our models suggest that the northern Red Sea has an asymmetric basement surface with the western side deeper than the eastern side. The results indicate the presence of oceanic crust in the central and southern parts of the Red Sea, but not in the north. The very thin crust and interpreted oceanic crustal density in the central Red Sea suggest that this area is fully oceanic although possibly quite young. [ABSTRACT FROM AUTHOR]

The article presents a study which estimates herd seroprevalence with Maedi-Visna infection in Manitoba sheeps. The study selected herds for testing and an Aussie Vet calculator was used for prevalence estimation. Results show that herd level seroprevalence is 25.10% and animal level seroprevalence is 2.47%, and herd size is connected with seroprevalence herd status. The study concludes that there is a low seroprevalence stability in Manitoba even without a systematic disease control program.

The article discusses a study on the prevalence and distribution of Baylisascaris procyonis in urban raccoons in Winnipeg, Manitoba. The study suggested that carriage of Baylisascaris procyonis, a species-adapted ascarid and a cause of clinical larva migrans in animals, is widespread in raccoons in the urban ecosystem. It also proposed the treatment of raccoon latrines as infectious sites and the initiation of efforts on limiting access of pets and people at risk to the infected sites.

- Abstract
This qualitative study examined the impact of a six-step framework for work-specific vocabulary instruction in adult English language learners (ELLs). Guided by research in English as a second language (ESL) methodology and the transactional theory, the researchers sought to unveil how these processes supported the acquisition and application of work-specific vocabulary in three adult ELLs. Data were collected in two levels, before and after training. The first data analysis identified and used two themes to develop training modules’ curriculum: (a) policies and procedures related to state and federal regulations and (b) customer service. After participants completed training, the second data analysis identified two additional themes transcending across the three cases: (a) employees’ views in English language proficiency skills and (b) growth in writing within their own continuum of English language development. Data revealed how an explicit, work-specific vocabulary instruction approach has the potential to increase ELLs’ varying levels of English language proficiency, acquisition, and application of work-specific vocabulary, and, simultaneously, confidence in how they view and use English in the workplace.

44. Removal of cultural noise from high-resolution aeromagnetic data using a two stage equivalent source approach

- Abstract
High-resolution aeromagnetic surveys are commonly used to locate subtle anomalies that are important in mineral and oil exploration. However, such anomalies, especially in highly populated areas, are often masked by undesirable magnetic signals from near surface man-made objects – known as ‘cultural noise’ – making post processing and interpretation of the aeromagnetic data difficult. Magnetic data need to be cleaned of this cultural noise before applying advanced processing and interpretation methods. Conventional algorithms for cultural noise removal tend to identify and remove noise signals, either manually or using non-linear filters. These methods are often combined with Fast Fourier Transform filters to smooth the result. These algorithms usually introduce artificial anomalies, have difficulty interpolating across edited sections and rarely yield clean data. For these reasons, we have developed a semi-automated two stage equivalent source approach to remove cultural noise and image subtle geological anomalies. A theoretical example that combines a magnetic anomaly due to a dyke with three cultural noise sources is used to test the effectiveness of the proposed method. Comparison of the equivalent source and conventional results shows that the equivalent source method more closely recovers the original magnetic data. We then demonstrate the practical utility of the two stage equivalent source approach using a high-resolution aeromagnetic dataset from Harberton Bridge, Ireland.

- Abstract
By the beginning of July 2009 the West Midlands had seen more cases of novel H1N1 influenza (swine flu) than any other region in the UK. Over a three-week period almost 850 people presented to Heartlands Hospital with flu-like symptoms. Of those admitted 52 adults were subsequently confirmed as having H1N1 infection. Most were younger than 30 and not from traditional influenza risk groups. The main risk factor for severe disease was asthma, and to a lesser extent pregnancy and obesity. Seven patients were admitted to intensive care and five developed an acute lung injury requiring prolonged admission. Two patients required extra corporeal membrane oxygenation and one died. Despite increased workload normal clinical services were unaffected. The hospital was not closed to admissions nor was it paralysed by staff absence. With a predicted second wave expected at the end of 2009, efforts to maintain effective community assessment remain crucial.
