‘SW049029104’ (Reg. No. CV‐1053, PI 658599) soft red winter (SRW) wheat (Triticum aestivum L.) was developed and released by the Virginia Agricultural Experiment Station in March 2009. SW049029104 was derived from the cross ‘38158’ (PI 619052)/Pioneer variety 2552//‘Roane’ and was tested under the experimental number VA04W‐90. SW049029104 is a broadly adapted, high‐yielding, moderately short, semidwarf (Rht2) cultivar that is resistant to powdery mildew [caused by Blumeria graminis (DC.) E.O. Speer] and Fusarium head blight (caused by Fusarium graminearum Schwabe). In the 2009 USDA‐ARS Uniform Southern SRW Wheat Nursery conducted at 25 locations, SW049029104 ranked first among 40 entries for grain yield (4889 kg ha−1) and fourth for grain volume weight (73.2 kg hL−1). The milling and baking qualities of SW049029104 exceeded those of ‘USG 3555’ and Pioneer brand 26R61. Flour softness and cookie‐spread diameter of SW049029104 (61.5–64.8 g 100 g−1 and 18.39–18.48 cm) exceeded those of USG 3555 (57.9–61.1 g 100 g−1 and 18.09–18.21 cm) and Pioneer brand 26R61 (54.5–61.1 g 100 g−1 and 18.12–18.13 cm). While flour protein concentration of SW049029104 (8.55–8.66 g 100 g−1) was lower than that of USG 3555 (8.88–9.10 g 100 g−1) and Pioneer brand 26R61 (9.65–9.66 g 100 g−1), its gluten strength, assessed via lactic acid solvent retention capacity (124.7–129.7 g 100 g−1), exceeded that of USG 3555 (118.9–124.0 g 100 g−1) and Pioneer brand 26R61 (113.5–126.0 g 100 g−1).

‘Snowglenn’ (Reg. No. CV‐1054, PI 659070) winter durum wheat (Triticum turgidum subsp. durum) developed and tested as VA05WD‐40 by the Virginia Agricultural Experiment Station was released in March 2008. Snowglenn was derived from the three‐way cross N1291–86/N1439–83//‘Alidur’. Snowglenn is a full‐season, medium‐height, winter durum wheat having good winter hardiness, high grain volume weight, and moderate resistance to Fusarium head blight [caused by Fusarium graminearum (Schwabe)]. In Virginia, Snowglenn was the highest‐yielding winter durum line tested in 2006 (5308 kg ha−1) and 2008 (4824 kg ha−1). Data from Austria indicates that Snowglenn is moderately susceptible to powdery mildew [caused by Blumeria graminis (DC) E.O. Speer], leaf rust (caused by Puccinia triticina Eriks.), and leaf blotch (caused by Septoria tritici Roberge in Desmaz.). Grain of Snowglenn has satisfactory quality for use in blends with traditional spring durum grain for pasta production.

‘Snowmass’ (Reg. No. CV‐1050, PI 658597) hard white winter wheat (Triticum aestivum L.) was developed by the Colorado Agricultural Experiment Station and released in July 2009 through a marketing agreement with the Colorado Wheat Research Foundation. In addition to researchers at Colorado State University (CSU) and Kansas State University (KSU), USDA‐ARS researchers at Manhattan, KS, St. Paul, MN, and Pullman, WA, participated in its development. Snowmass was selected from the cross KS96HW94//‘Trego’/CO960293 made in 1999 at Fort Collins, CO, with the initial F1 between Trego and CO960293 made by KSU at Hays, KS. KS96HW94 is an unreleased experimental line from KSU with the pedigree ‘Arlin’ (PI 564246)/KS89H20. Trego is a hard white winter wheat cultivar released by KSU in 1999. CO960293 is an unreleased experimental line from CSU from which the germplasm release CO960293–2 was selected. Snowmass was selected as an F6:7 line in July 2006 and assigned experimental line number CO03W054–2. Snowmass was released because of its superior grain yield under nonirrigated production conditions in eastern Colorado; its resistance to Wheat streak mosaic virus, stripe rust (Puccinia striiformis f. sp. tritici), and stem rust (P. graminis f. sp. tritici); and its superior milling and bread‐baking quality.

Research to develop ‘CPCL 99–4455’ (Reg. No. CV‐142; PI 659802) sugarcane (a complex hybrid of Saccharum spp.) was initiated by the United States Sugar Corporation (USSC) and completed cooperatively by the USDA‐ARS, the University of Florida, and the Florida Sugarcane League, Inc. CPCL 99–4455 was released to growers in Florida on 15 Dec. 2009. CPCL 99–4455 was selected from a cross of the USSC proprietary genotype CL 90–4643 × ‘CP 84–1198’ made at Clewiston, FL on 22 Dec. 1998. The female parent, CL 90–4643, has high yields of cane and sucrose but it is not used commercially by the USSC because of susceptibility to Sugarcane mosaic virus strain E. The male parent, cultivar CP 84–1198, has moderately high commercial recoverable sucrose (CRS) and cane yields and has been grown commercially on about 1–5% of Florida's sugarcane acreage since 1996. CPCL 99–4455 is moderately resistant to smut (caused by Ustilago scitaminea Sydow & P. Sydow), brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), and Sugarcane mosaic virus strain E. CPCL 99–4455 is expected to be used mostly on organic (muck) soils in Florida, where it had high CRS and acceptable yields of cane in our tests.

Near‐isogenic lines (NILs) were developed in barley (Hordeum vulgare L.) and evaluated for resistance to barley stripe rust (BSR; incited by Puccinia striiformis f. sp. hordei) and agronomic potential. These NILs, the BISON lines (Barley stripe rust resistance ISOgeNic), represent BSR resistance quantitative trait loci (QTL) alleles introgressed individually and in all possible combinations into a susceptible background ‘Baronesse’ (PI 568246). The lines are BISON 1H (Reg. No. GS‐4, PI 659445), BISON 4H (Reg. No. GS‐8, PI 659449), BISON 5H (Reg. No. GS‐10, PI 659451), BISON 1H +4H (Reg. No. GS‐5, PI 659446), BISON 1H+5H (Reg. No. GS‐7, PI 659448), BISON 4H+5H (Reg. No. GS‐9, PI 659450), BISON 1H+4H+5H (Reg. No. GS‐6, PI 659447), BISON 7H (Reg. No. GS‐11, PI 659452), and BISON 0‐QTL (Reg. No. GS‐12, PI 659453), and the QTL donors were BCD12 (Reg. No. GS‐2, PI 659443), BCD47 (Reg. No. GS‐3, PI 659444), and D3–6/B23 (Reg. No. GS‐1, PI 659442). The experimental lines and released line names are the same. Phenotypic data, in conjunction with genotypic data, were used to characterize QTL allele introgressions and to assess the impact of these introgressions and pyramiding on agronomic performance. The BISON lines represent valuable sources of BSR resistance in an improved background, and performance data provide useful assessments of QTL allele introgressions (alone and in combination) and quantitative versus qualitative disease resistance.
Phenolic-Compound-Extraction Systems for Fruit and Vegetable Samples
Authors: Garcia-Salas Patricia , Morales-Soto Aranzazu , Segura-Carretero Antonio , Fernández-Gutiérrez Alberto
Published: December 2010

This paper reviews the phenolic-compound-extraction systems used to analyse fruit and vegetable samples over the last 10 years. Phenolic compounds are naturally occurring antioxidants, usually found in fruits and vegetables. Sample preparation for analytical studies is necessary to determine the polyphenolic composition in these matrices. The most widely used extraction system is liquid-liquid extraction (LLE), which is an inexpensive method since it involves the use of organic solvents, but it requires long extraction times, giving rise to possible extract degradation. Likewise, solid-phase extraction (SPE) can be used in liquid samples. Modern techniques, which have been replacing conventional ones, include: supercritical fluid extraction (SFE), pressurized liquid extraction (PLE), microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE). These alternative techniques reduce considerably the use of solvents and accelerate the extraction process.
Multi-Sensor Person Following in Low-Visibility Scenarios
Authors: Sales Jorge , Marín Raúl , Cervera Enric , Rodríguez Sergio , Pérez Javier
Published: December 2010

Person following with mobile robots has traditionally been an important research topic. It has been solved, in most cases, by the use of machine vision or laser rangefinders. In some special circumstances, such as a smoky environment, the use of optical sensors is not a good solution. This paper proposes and compares alternative sensors and methods to perform a person following in low visibility conditions, such as smoky environments in firefighting scenarios. The use of laser rangefinder and sonar sensors is proposed in combination with a vision system that can determine the amount of smoke in the environment. The smoke detection algorithm provides the robot with the ability to use a different combination of sensors to perform robot navigation and person following depending on the visibility in the environment.
A Review of Direct Neck Measurement in Occupational Settings

Published: December 2010

No guidelines are available to orient researchers on the availability and applications of equipment and sensors for recording precise neck movements in occupational settings. In this study reports on direct measurements of neck movements in the workplace were reviewed. Using relevant keywords two independent reviewers searched for eligible studies in the following databases: Cinahal, Cochrane, Embase, Lilacs, PubMed, MEDLINE, PEDro, Scopus and Web of Science. After applying the inclusion criteria, 13 articles on direct neck measurements in occupational settings were retrieved from among 33,666 initial titles. These studies were then methodologically evaluated according to their design characteristics, exposure and outcome assessment, and statistical analysis. The results showed that in most of the studies the three axes of neck movement (flexion-extension, lateral flexion and rotation) were not simultaneously recorded. Deficiencies in available equipment explain this flaw, demonstrating that sensors and systems need to be improved so that a true understanding of real occupational exposure can be achieved. Further studies are also needed to assess neck movement in those who perform heavy-duty work, such as nurses and electricians, since no report about such jobs was identified.

Published: December 2010

Conducting polymer 3D microelectrodes have been fabricated for possible future neurological applications. A combination of micro-fabrication techniques and chemical polymerization methods has been used to create pillar electrodes in polyaniline and polypyrrole. The thin polymer films obtained showed uniformity and good adhesion to both horizontal and vertical surfaces. Electrodes in combination with metal/conducting polymer materials have been characterized by cyclic voltammetry and the presence of the conducting polymer film has shown to increase the electrochemical activity when compared with electrodes coated with only metal. An electrochemical characterization of gold/polypyrrole electrodes showed exceptional electrochemical behavior and activity. PC12 cells were finally cultured on the investigated materials as a preliminary biocompatibility assessment. These results show that the described electrodes are possibly suitable for future in-vitro neurological measurements.
Sustainability, Learning and Capability: Exploring Questions of Balance
Authors: Scott William A. H. , Gough Stephen R.
Published: December 2010

It is argued that sustainable development makes best sense as a social learning process that brings tangible and useful outcomes in terms of understanding and skills, and also reinforces the motivation and capability for further learning. Thus, there are always balances to be struck between a broad-based, wide-ranging education and a more specialist one; between a focus on ideas themselves, and on their application in social or economic contexts; and between keeping ideas separate, and integrating them. This paper will explore the nature of such balances, and the issues to bear in mind when striking them, focusing on schools, university and college contexts within the United Kingdom.
Jaagsiekte Sheep Retrovirus Biology and Oncogenesis
Authors: Hofacre Andrew , Fan Hung
Published: December 2010

Jaagsiekte sheep retrovirus (JSRV) is the causative agent of a lung cancer in sheep known as ovine pulmonary adenocarcinoma (OPA). The disease has been identified around the world in several breeds of sheep and goats, and JSRV infection typically has a serious impact on affected flocks. In addition, studies on OPA are an excellent model for human lung carcinogenesis. A unique feature of JSRV is that its envelope (Env) protein functions as an oncogene. The JSRV Env-induced transformation or oncogenesis has been studied in a variety of cell systems and in animal models. Moreover, JSRV studies have provided insights into retroviral genomic RNA export/expression mechanisms. JSRV encodes a trans-acting factor (Rej) within the env gene necessary for the synthesis of Gag protein from unspliced viral RNA. This review summarizes research pertaining to JSRV‑induced pathogenesis, Env transformation, and other aspects of JSRV biology.
Ultrafine metallic Fe nanoparticles: synthesis, structure and magnetism
Authors: Margeat Olivier , Respaud Marc , Amiens Catherine , Lecante Pierre , Chaudret Bruno
Published: December 2010

The results of the investigation of the structural and magnetic (static and dynamic) properties of an assembly of metallic Fe nanoparticles synthesized by an organometallic chemical method are described. These nanoparticles are embedded in a polymer, monodisperse, with a diameter below 2 nm, which corresponds to a number of around 200 atoms. The X-ray absorption near-edge structure and Mössbauer spectrum are characteristic of metallic Fe. The structural studies by wide angle X-ray scattering indicate an original polytetrahedral atomic arrangement similar to that of β-Mn, characterized by a short-range order. The average magnetic moment per Fe atom is raised to 2.59 µB (for comparison, bulk value of metallic Fe: 2.2 µB). Even if the spontaneous magnetization decreases rapidly as compared to bulk materials, it remains enhanced even up to room temperature. The gyromagnetic ratio measured by ferromagnetic resonance is of the same order as that of bulk Fe, which allows us to conclude that the orbital and spin contributions increase at the same rate. A large magnetic anisotropy for metallic Fe has been measured up to (3.7 ± 1.0)·105 J/m3. Precise analysis of the low temperature Mössbauer spectra, show a broad distribution of large hyperfine fields. The largest hyperfine fields display the largest isomer shifts. This indicates a progressive increase of the magnetic moment inside the particle from the core to the outer shell. The components corresponding to the large hyperfine fields with large isomer shifts are indeed characteristic of surface atoms.

Published: December 2010

Résumé Le service de psychopathologie de l’enfant et de l’adolescent du professeur Marie Rose Moro à l’hôpital Avicenne reçoit notamment des patients d’âge scolaire présentant des difficultés de langage oral et/ou écrit. Ces difficultés peuvent être apparentées à un trouble spécifique du langage (dysphasie pour le langage oral ou dyslexie pour le langage écrit), à un retard de parole et langage au sein de retard global du développement, à un contexte de bilinguisme ou encore à des troubles envahissants du développement. La réalité clinique de ces difficultés est encore complexifiée par les situations, fréquentes, d’appartenances pluriculturelles et de pratiques multilingues. Cet article propose de présenter les différents troubles du langage oral et écrit chez l’enfant, puis de faire un lien avec les pratiques cliniques, d’évaluation et de prise en charge, dans les situations de bilinguisme.
Les fantômes invisibles : silence parental et transmission traumatique
Authors: Giraud François
Published: December 2010

Résumé Beaucoup de familles migrantes sont originaires de pays affectés dans leur histoire récente par des guerres et des massacres. Souvent les parents, pour se préserver ou les protéger, ont du mal à revenir sur ces souvenirs traumatiques. D’une manière ou d’une autre, pourtant, les enfants en portent l’empreinte, soit comme victimes, soit parce que dans leur pathologie ressurgissent les fantômes du passé. Cela pose la nécessité, pour les cliniciens, d’être attentifs à cet aspect de la culture d’origine de ces enfants, surtout si la société n’a pas pu en développer un récit mémoriel.
Éléments pour une économie politique de la soutenabilité fondée sur le recul de la marchandise
Authors: Harribey Jean-Marie
Published: December 2010

Résumé Cet article essaie de formuler des éléments pour poser les bases d’une économie politique de soutenabilité dans ses deux dimensions : sociale et environnementale. Dans cette perspective, nous rappelons les limites de l’approche néoclassique de la soutenabilité faible, fondée sur l’hypothèse de substituabilité. Ces limites se retrouvent également au sein d’un courant écologiste néophysiocrate. Il s’ensuit que les procédures d’internalisation des effets externes restent prisonnières des mécanismes de marché. Aussi proposons-nous dans une seconde partie, à partir de la notion de bien public ou bien commun, de définir la soutenabilité sociale et la soutenabilité écologique dans une perspective forte, par la préservation des biens communs de l’humanité et par l’utilisation de la monnaie comme bien public qui permet de payer les services non marchands.

Published: December 2010

Résumé Cet article a pour objectif de mieux cerner les fondements institutionnels et organisationnels de la Responsabilité sociale de l’entreprise [RSE]. Nous cherchons dans un premier temps à comprendre les origines de l’appel généralisé en faveur de la RSE qui marque l’époque contemporaine. Nous distinguons un appel institutionnel symptomatique du déficit de régulation de l’ancien modèle fordiste et, plus largement, un appel sociétal, dû à une accélération du dévoilement des effets externes négatifs. Nous essayons ensuite de comprendre pourquoi les entreprises adhèrent massivement à ce projet de responsabilisation et décrivons les conditions qui autorisent l’opérationnalisation d’un tel projet. Nous dressons, pour terminer, l’inventaire des limites que nous semble poser le projet de régulation proposé par la RSE.
Tumor-Induced Disruption of Proximal TCR-Mediated Signal Transduction in Tumor-Infiltrating CD8+ Lymphocytes Inactivates Antitumor Effector Phase
Authors: Vazquez-Cintron Edwin J. , Monu Ngozi R. , Frey Alan B.
Published: December 2010

The presence in cancer tissue of Ag-specific, activated tumor infiltrating CD8+ T cells proves that tumors express Ags capable of eliciting immune response. Therefore, in general, tumor escape from immune-mediated clearance is not attributable to immunological ignorance. However, tumor-infiltrating lymphocytes are defective in effector phase function, demonstrating tumor-induced immune suppression that likely underlies tumor escape. Since exocytosis of lytic granules is dependent upon TCR-mediated signal transduction, it is a reasonable contention that tumors may induce defective signal transduction in tumor infiltrating T cells. In this review, we consider the biochemical basis for antitumor T cell dysfunction, focusing on the role of inhibitory signaling receptors in restricting TCR-mediated signaling in tumor-infiltrating lymphocytes.
A New Zlichovian (Early Devonian) Species of the Rugose Coral Genus Zelolasma From the Eids Formation of Ellesmere Island, Northwest Territories
Authors: Pedder A E H , Smith G P
Published: December 2010

Zelolasma, sensu stricto, is known from the Pragian of Tadzhikistan, late Pragian or early Zlichovian of New South Wales, early Zlichovian of Ellesmere Island, and Dalejan of Taymyr. Reported occurrences in the late Lochkovian of Salair and the Dalejan or
Eifelian of Gansu have yet to be substantiated. Forms resembling Zelolasma, but differing from it by lacking discrete adaxial septal fragments, are known from the Ludlow Series of New South Wales and the Upper Silurian (Ludlow or Pridolian equivalent) of the southern Urals. Zelolasma apsidi.ferum
sp. n. is described from high strata of the Eids Formation, 20.5 km west of the head of Sor Fiord, southwestern Ellesmere Island. The type horizon of the new coral is in the Polygnathus dehiscens Zone, which spans the Pragian/Zlichovian boundary. However, the age of the type stratum is judged to be
early Zlichovian, rather than late Pragian, because it overlies probable Zlichovian brachiopods, as well as spores dated approximately as middle Emsian (equivalent to late Zlichovian).
Andradite Garnet in Altered Basalt From Borup Fiord, Ellesmere Island, Northwest Territories
Authors: Tazaki K
Published: December 2010

Mineral chemistry and paragenesis of cavity-filling andradite garnet, epidote and prehnite in altered basalt collected from Borup Fiord, Ellesmere Island are described. The garnet is idiomorphic to sub-idiomorphic and dark brown to amber coloured. The ferrian
garnet part contains more than 30.0 per cent Fe 2O3 and less than 1.0 per cent A12O3. The birefringent rim of the garnet contains more than 8.0 percent A12O3. Epidote occurs as euhedral to subhedral cavity fillings and a replacement of plagioclase. All analyses of epidote range from Ps 17 to Ps 36,
Euhedral prehnite usually forms overgrowths on epidote in the cavities. The ferrian prehnite contains less than 8.0 per cent Fe 2O3. There are two equilibrium temperatures calculated from coexisting garnet and epidote. These results suggest that the various mineralization stages were preserved
metastably in the same specimen. The garnet and associated cavity-filling minerals may have been produced during local hydrothermal alteration of the Esayoo basait in the Borup Fiord region.
A Shallow Seismic Survey On the Intertidal Flats At Pangnirtung, Baffin Island, Northwest Territories
Authors: Pullan S E , Hunter J A , Gilbert R
Published: December 2010

A hammer seismic survey was conducted along selected lines across the intertidal flats at Pangnirtung, Baffin Island, in an attempt to delineate the bedrock surface beneath the sediments. The results indicate that bedrock drops off steeply from shore where the
fiats are narrow, whereas it forms a supporting platform beneath the extensive fiats at the mouth of the Duval River. Approximately 30 m of sediment lie above this bedrock platform. There is some evidence of boulders or groups of boulders buried in these sediments, but the density of these cannot be
estimated.
New Devonian Rugose Corals of Probable Late Dalejan Age From the Bird Fiord Formation of southwestern Ellesmere Island, Northwest Territories
Authors: Pedder A E H , Goodbody G H
Published: December 2010

The Bird Fiord Formation, between Blubber Point and the area north of Muscox Fiord, is divided into four lithological units, informally designated Units 1 to 4. Unit 3 contains a rich benthic, marine fauna, including the corals described in this paper. Its age is
deduced to be probably late Dalejan (late Early Devonian), on the basis of conodonts, brachiopds and corals. The genera Spongophylloides, Actinocystis, Grypophyllwn, Dubrovia, Salairophyllwn, Tonkinaria and Neogrypophyllum are discussed in preparation for the proposal of a new ptenophyllid genus,
named Ellesmerelasma. Four new species and a new subspecies are introduced. They are Lekanophyllum foliatum, EUesmerelasma pu.mile, Mansuyphyllum uyenoi avernale, M. versicularium and M. comsolwn.
Direct geophysical evidence for displacement along Nares Strait Canada - Greenland] from low-level aeromagnetic data: a progress report
Authors: Hood P J , Bower M E , Hardwick C D , Teskey D J
Published: December 2010

A Iow level aeromagnetic reconnaissance of Nares Strait shows a sinistraI offset of approximately 2.5 km in a band of .500-qamma anomalies extending from Fache Peninsula on Ellesmere Island to the southern side of the Humboldt Glacier on Greenland. A line of
isolated 200 gamma anomalies extends north from Judge Daly Promontory along Robeson Channel to the Arctic Ocean. These anomalies, which appear to be due to a swarm of closely spaced dykes, line up with the prominent fault zone on Judge Daly Promontory, which has been mapped with a 19 km sinistraI
displacement. Volcanic fragments with an olivine-basaltic composition have been found in Tertiary rocks along the fault zone and the aeromagnetic evidence also suggests that the dyke system extends across Judge Daly Promontory. Thus it is concluded that at least 19 km of sinistral strike-slip
displacement has occurred along the Strait itself, supporting Weqener's 1912 hypothesis.
Stratigraphic subdivision of the Isachsen and Christopher formations [lower cretaceous], Arctic Islands
Authors: Embry A F
Published: December 2010

The Isachsen Formation, a Lower Cretaceous sandstone-dominant unit, is herein divided into three members, named in ascending order: Paterson Island, Randon and Walker Island. The Paterson Island and Walker Island members are sandstone-dominant units of delta
front and delta plain origin and are separated by the shale-siltstone-dominant Randon Member, which is of offshore marine shelf origin. The Christopher Formation, a Lower Cretaceous, shale-siltstone-dominant unit, which overlies the Isachsen Formation, is divided into two members, named in ascending
order: Invincible Point and Macdougall Point. Bath members are of offshore marine shelf origin, and the boundary between the two is placed at the top of a widespread sandstone-siltstone interval that occurs in the middle of the Christopher Formation.
Lower paleozoic stratigraphy of northwestern Melville Island, District of Franklin
Authors: Robson M J
Published: December 2010

The Lower Paleozoic succession in the Canrobert Hills comprises three formations: the Canrobert, the lbbett Bay and the Blackley. The resedimented carbonate rocks of the Canrobert Formation (Upper Cambrian? to Lower Ordovician) are interpreted as slope deposits.
They are overlain by black shales and cherts of the lbbett Bay Formation which ranges in age from the early Ordovician to Middle Devonian, and is interpreted as a deep water basinal deposit. Above the Ibbett Bay, the Blackley Formation, comprising siltstones, mudrocks, and turbidite packages, forms
the local base of the Middle Devonian clastic wedge that represents the closing phase of sedimentation in the Franklinian Geosyncline.

Authors: Pedder A E H
Published: December 2010

Lochkovian rugose corals from the Canadian Arctic Archipelago are illustrated for the first time. Tryplasma sp. and Lythophyllum thorsteinssoni sp. n. are described from the delta or pesavis Zone, in the upper member of the Drake Bay Formation on northwestern
Prince of Wales Island. Adinophyllum smithi gen. et sp. n. (family Mucophyllidae) is described from beds equivalent to either the eurekaensis or delta Zone of the same member and region. Stylopleura julli Pedder, Mochlophyllurn sp., Lekanophyllum sp. and Lyrielasma sp. are illustrated and discussed
from beds equivalent to the eurekaensis Zone, in the middle unit of the Sophia Lake Formation on eastern Saillie Hamilton Island. Corals from ail three locations are well dated on evidence provided by brachiopods, trilobites, conodonts and graptolites. The unnamed species of Mochlophyllum and
Lekanophyllum are the oldest known representatives of these genera.
Radiocarbon dating with accelerator mass spectrometry: results from Ellesmere Island, District of Franklin
Authors: Blake W
Published: December 2010

Radiocarbon dating by means of accelerator mass spectrometry (AMS) has two great advantages over conventional dating: 1) much smaller samples can be handled and 2) counting time is significantly shorter. Three examples are given for Holocene-age material from
east-central Ellesmere Island. The results demonstrate the potential use of this technique as a powerful research tool in studies of Quaternary chronology. Individual fragments of marine shells as small as 0.1 g have been dated successfully at the IsoTrace Laboratory, University of Toronto. In the
case of an aquatic moss from a lake sediment core, an increment 0.5 cm thick could be used instead of a 5 cm-thick slice, thus allowing a much more precise estimate of the onset of organic sedimentation.

Tide-dominated shelf sedimentation prevailed during deposition of that part of the Wolstenholme Formation seen by the writer, and was interrupted twice by meandering stream sedimentation and once by plateau basalt volcanism. Prodelta-type sediments occur locally
at two stratigraphic positions. Part of the Dundas Formation was deposited in a subtidal restricted basin while the overlying Narssârssuk Formation contains coastal sabkha deposits. Abrupt changes in lithologies and environments may be due ta syndepositional faulting. Easterly sedimentary
transport prevailed in southeast Ellesmere Island and southwesterly transport prevailed in western Greenland. A nearby land source probably Jay immediately west of the Thule Group on Ellesmere Island. The Thule Group and Bylot Supergroup were probably deposited, at least in part, as a continuous
deposit in a single basin during opening of the Poseidon Ocean at 1200-1250 Ma.
High Grade Metamorphic Rocks of northwestern Melville Peninsula, District of Franklin
Authors: Schau M , Beckett M
Published: December 2010

High grade metamorphic rocks are exposed in the Encampment Bay area. Preliminary results indicate that a tonalitic-granodioritic plutonic suite was intruded by granite and mafic dykes and later unconformably(?) overlain by sediments correlated with the 2.9 Ga
Prince Albert Group. Shallow dipping slabs of dry basement and wet supracrustals were tectonically stacked and transported ta deep levels within the crust where they were metamorphosed and partially melted under granulite and upper amphibolite conditions, probably during late Archean time. They were
then uplifted possibly along the previous shallow dipping discontinuities. Northwest trending mafic dykes cut the rising mass and were metamorphosed ta varying amphibolite facies grades probably conjointly with emplacement of a late pegmatite swarm in early Proterozoic time. Steep, east-west faults
of Proterozoic age cut the region and late Proterozoic clastic sediments were deposited onto the basement after which faults, reactivated and new, cut the area. The region was peneplaned by early Ordovician time before the mid-Devonian uplift of the Melville Peninsula horst.
VegetationGeologyClimate Relationships of western Melville Island, District of Franklin
Authors: Edlund S A
Published: December 2010

Bath surficial geology and climate closely control plant assemblages on western Melville Island. Vegetation falls into two broad categories: calciphilous communities on weakly ta moderately alkaline substrates, and acetophilic communities on acidic substrates.
Superimposed on this lithological control is the control imposed by climate. The region is subdivided into five bioclimate zones including a newly defined one - Zone O - unvegetated areas recently emerged from under neoglacial ice and snow. An unusually vegetation-rich zone (Zone 4) covers a
significant area of western Melville Island, making it the richest area of the central and western Queen Elizabeth Islands, comparable ta the flora and communities in the Fosheim Peninsula region of Ellesmere Island. This zone may represent a disjunct of Mid Arctic vegetation into the region
generally considered ta be High Arctic.
Stratigraphic Subdivision of the Awingak Formation [Upper Jurassic] and Revision of the Hiccles Cove Formation [Middle Jurassic] Sverdrup Basin, Arctic Islands
Authors: Embry A F
Published: December 2010

The Awingak Formation is a sandstone-dominant unit of Oxfordian to Tithonian (Late Jurassic) age and it occurs in the eastern and southeastern portion of the Sverdrup Basin. Throughout most of its extent, three members can be recognized within the formation: a
lower sandstone, a media! shale/siltstone, and an upper sandstone. These three members are given formal status and are named, in ascending order: Cape Lockwood, Hot Wea ther and Slidre members. Correlation of the three members of the Awingak Formation and the underlying Ringnes Formation with
sections on western Melville Island and Prince Patrick Island, has revealed that strata previously assigned to the upper portion of the Hiccles Cove Formation are stratigraphically equivalent to the Ringnes Formation and the Cape Lockwood Member of the Awingak Formation. In order to achieve a
consistent stratigraphic nomenclature for the Middle-Upper Jurassic succession of the Sverdrup Basin, the upper boundary of the Hiccles Cove Formation is redefined to exclude strata equivalent to the Ringnes and Awingak formations from the Hiccles Cove.
Bedrock and Surficial Geology of Cumberland Sound, Northwest Territories
Authors: Maclean B , Williams G L , Jennings A , Blakeney C
Published: December 2010

The southwestern half and inner parts of Cumberland Sound are underlain by Precambrian rocks whereas the outer part is underlain by Ordovician carbonates which extend northwestward for 70 km. Cretaceous (Barremian-Cenomanian) semi-consolidated mudstones and
siltstones underlie the northeastern half of Cumberland Sound. Palynomorph assemblages indicate deposition of the Cretaceous strata occurred in a nonmarine to marginal marine environment. Cumberland Sound is a graben that appears to have been active subsequent to Barremian­Cenomanian time and
possibly earlier. The main accumulation of surficial sediments is in the outer half of the northeastern side of the sound. The sequence, 25-50 m thick, includes both unstratified and stratified sediments. Surficial sediments in southwestern and inner parts of the sound form a thin (< 1-2
m) discontinuous caver over rough Precambrian rocks and comprise lag gravels and sands.
A Reconnaissance Study of the Bedrock and Surficial Geology of Hudson Strait, Northwest Territories
Authors: Maclean B , Williams G L , Sanford B V , Klassen R A , Blakeney C , Jennings A
Published: December 2010

The preservation of Paleozoic and possibly younger strata beneath the strait is controlled by half grabens at the eastern and western ends, and in the central part by a regional synclinal structure. Preliminary lithologie correlations of Paleozoic strata in
Hudson Strait were made with rocks exposed on Southampton, Coats, and Manse! islands in northern Hudson Bay and in the Premium Homestead Akpatok L-26 well in Ungava Bay. These correlations and regional stratigraphie relationships recorded on seismic profiles suggest that carbonate rocks of
Ordovician age underlie most of the western part of the strait, but occur together with Silurian and possibly younger rocks in the eastern part. The seismic data also suggest that 2000 m or more of strata may be present in the area. Surficial sediments include glacial till and stratified sediments.
Greatest accumulations, 95 m and 130 m, are in the eastern and western basins, respectively. Moraines have been observed on bath north and south sides and in the western part of the strait. In places they include more than one till.
Geochronology of the Black River volcanic complex, Nunavut - Northwest Territories; Radiogenic age and isotopic studies: Report 14
Authors: Villeneuve M , Lambert M , van Breemen O , Mortensen J
Published: December 2010

Five samples from the Back River volcanic complex of the eastern Slave Province provide age constraints on the stratigraphy of the area. Tuff from the Innerring sequence, at the stratigraphic base of the complex, is dated at 2708.5 ± 0.8 Ma. This age is 16
Maolder than a previously reported age of 2692 ± 2 Ma from rhyolite of the overlying Thlewycho sequence. An age determination on an intrusive rhyolite gives a poorly defined age between ca. 2660 Maand 2690 Ma. A felsic sill that intrudes the Beechy Lake turbidite sequence, which in turn onlaps
the volca- nic complex, indicates an age of 2637 +8/-6 Ma. Detrital zircons from another section of Beechy Lake turbidite indi- cate that deposition postdated 2620 Ma, although the bulk of detritus was locally shed from the volcanic complex. A metagabbro dyke yielded baddeleyite, giving an age of
2586 ± 5 Ma.
Baddeleyite U-Pb age of metadiabase near Key Harbour, Britt domain, Grenville Province, Ontario; Radiogenic age and isotopic studies: Report 14
Authors: Davidson A , van Breemen O
Published: December 2010

Many occurrences of metadiabase in the parautochthonous belt of the Grenville Province in Ontario have a geochemical signature indistinguishable from that of Sudbury diabase in the adjacent Superior and Southern provinces, and some bodies close to the Grenville
Front are known to have the same ca. 1.24 Ga age. However, dating of baddeleyite in metadiabase with Sudbury-type chemistry from a small mass enclosed in orthogneiss near Key Harbour shows it to be at least 200 Maolder than Sudbury diabase, which casts doubt on the use of rock chemistry as a
correlation tool for tracing the extent of Sudbury metadiabase within the parautochthon. Despite this, the common chemical signature of metadiabase of whatever age in the parautochthonous footwall of the allochthon boundary thrust zone serves as a distinction from the 1.17 1.15 Ga coronitic
metagabbro in the hanging wall, the two being spatially mutually exclusive.
A critical look at spatial scale choices in satellite-based aerosol indirect effect studies
Authors: Grandey B. S. , Stier P.
Published: December 2010

Abstract. Analysing satellite datasets over large regions may introduce spurious relationships between aerosol and cloud properties due to spatial variations in aerosol type, cloud regime and synoptic regime climatologies. Using MODerate resolution Imaging Spectroradiometer data, we calculate relationships between aerosol optical depth τa derived liquid cloud droplet effective number concentration Ne and liquid cloud droplet effective radius re at different spatial scales. Generally, positive values of dlnNedlnτa are found for ocean regions, whilst negative values occur for many land regions. The spatial distribution of dlnredlnτa shows approximately the opposite pattern, with generally postive values for land regions and negative values for ocean regions. We find that for region sizes larger than 4° × 4°, spurious spatial variations in retrieved cloud and aerosol properties can introduce widespread significant errors to calculations of dlnNedlnτa and dlnredlnτa. For regions on the scale of 60° × 60°, these methodological errors may lead to an overestimate in global cloud albedo effect radiative forcing of order 80% relative to that calculated for regions on the scale of 1° × 1°.

Abstract. During the FROST-2 (FReezing Of duST) measurement campaign conducted at the Leipzig Aerosol Cloud Interaction Simulator (LACIS), we investigated changes in the ice nucleation properties of 300 nm Arizona Test Dust mineral particles following thermochemical processing by varying amounts and combinations of exposure to sulphuric acid vapour, ammonia gas, water vapour, and heat. The processed particles' heterogeneous ice nucleation properties were determined in both the water subsaturated and supersaturated humidity regimes at −30 °C and −25 °C using Colorado State University's continuous flow diffusion chamber. The amount of sulphuric acid coating material was estimated by an aerosol mass spectrometer and from CCN-derived hygroscopicity measurements. The condensation of sulphuric acid decreased the dust particles' ice nucleation ability in proportion to the amount of sulphuric acid added. Heating the coated particles in a thermodenuder at 250 °C – intended to evaporate the sulphuric acid coating – reduced their freezing ability even further. We attribute this behaviour to accelerated acid digestion of ice active surface sites by heat. Exposing sulphuric acid coated dust to ammonia gas produced particles with similarly poor freezing potential; however a portion of their ice nucleation ability could be restored after heating in the thermodenuder. In no case did any combination of thermochemical treatments increase the ice nucleation ability of the coated mineral dust particles compared to unprocessed dust. These first measurements of the effect of identical chemical processing of dust particles on their ice nucleation ability under both water subsaturated and mixed-phase supersaturated cloud conditions revealed that ice nucleation was more sensitive to all coating treatments in the water subsaturated regime. The results clearly indicate irreversible impairment of ice nucleation activity in both regimes after condensation of concentrated sulphuric acid. This implies that the sulphuric acid coating caused permanent chemical and/or physical modification of the ice active surface sites; the possible dissolution of the coating during droplet activation did not restore all immersion/condensation-freezing ability.
Characterisation of the rhizoremediation of petroleum-contaminated soil: effect of different influencing factors

Published: December 2010

Abstract. Pilot experiments were conducted to analyse the effect of different environmental factors on the rhizoremediation of petroleum-contaminated soil. Different plant species (cotton, ryegrass, tall fescue and alfalfa), the addition of fertilizer, different concentrations of total petroleum hydrocarbons (TPH) in the soil, bioaugmentation with effective microbial agents (EMA) and plant growth-promoting rhizobacteria (PGPR) and remediation time were tested as influencing factors during the bioremediation process of TPH. The results show that the remediation process can be enhanced by different plant species. The order of effectiveness of the plants was the following: tall fescue > ryegrass > alfalfa > cotton. The degradation rate of TPH increased with increased fertilizer addition, and a moderate urea level of 20 g N (Nitrogen)/m2 was best for both plant growth and TPH remediation. A high TPH content is toxic to plant growth and inhibits the degradation of petroleum hydrocarbons. The results showed that a 5% TPH content gave the best degradation in soil planted with ryegrass. Bioaugmentation with different bacteria and PGPR yielded the following results for TPH degradation: cotton+EMA+PGPR > cotton+EMA > cotton+PGPR > cotton > control. Rapid degradation of TPH was found at the initial period of remediation caused by the activity of microorganisms. A continuous increase of degradation rate was found during the 30–90 days period followed by a slow increase during the 90–150 days period. These results suggest that rhizoremediation can be enhanced with the proper control of different influencing factors that affect both plant growth and microbial activity in the rhizosphere environment.
Emergency Mental Health: Lessons Learned From Flight 3407
Authors: Homish Gregory G. , Frazer Bonita S. , McCartan Daniel P. , Billittier Anthony J.
Published: December 2010

Emergency mental health (EMH), a field that is often not well represented when considering emergency preparedness, is nonetheless a vital component to any disaster response. Emergency mental health issues must be considered not only for victims of disasters and their families, friends, and coworkers but also for both on-scene and off-scene responders and members of the community who may have witnessed the disaster. This article describes the EMH preparation for and response to the crash of Continental Airlines flight 3407 in western New York on February 12, 2009, killing all 49 crew and passengers on board and 1 person on the ground. It describes aspects of the response that went as planned and highlights areas for improvement. The lessons learned from this EMH preparation and response can be used to inform future planning for disaster response.
