We report the detection of diffuse Lyα emission, or Lyα halos (LAHs), around star-forming galaxies at z ≈ 3.78 and 2.66 in the NOAO Deep Wide-Field Survey Boötes field. Our samples consist of a total of ∼1400 galaxies, within two separate regions containing spectroscopically confirmed galaxy overdensities. They provide a unique opportunity to investigate how the LAH characteristics vary with host galaxy large-scale environment and physical properties. We stack Lyα images of different samples defined by these properties and measure their median LAH sizes by decomposing the stacked Lyα radial profile into a compact galaxy-like and an extended halo-like component. We find that the exponential scale-length of LAHs depends on UV continuum and Lyα luminosities, but not on Lyα equivalent widths or galaxy overdensity parameters. The full samples, which are dominated by low UV-continuum luminosity Lyα emitters (M
UV ≳ −21), exhibit LAH sizes of 5–6 kpc. However, the most UV- or Lyα-luminous galaxies have more extended halos with scale-lengths of 7–9 kpc. The stacked Lyα radial profiles decline more steeply than recent theoretical predictions that include the contributions from gravitational cooling of infalling gas and from low-level star formation in satellites. However, the LAH extent matches what one would expect for photons produced in the galaxy and then resonantly scattered by gas in an outflowing envelope. The observed trends of LAH sizes with host galaxy properties suggest that the physical conditions of the circumgalactic medium (covering fraction, H i column density, and outflow velocity) change with halo mass and/or star formation rates.

We analyze new far-ultraviolet spectra of 13 quasars from the

COS-Halos survey that cover the H i Lyman limit of 14 circumgalactic medium (CGM) systems. These data yield precise estimates or more constraining limits than previous COS-Halos measurements on the H i column densities

. We then apply a Monte-Carlo Markov chain approach on 32 systems from COS-Halos to estimate the metallicity of the cool (

K) CGM gas that gives rise to low-ionization state metal lines, under the assumption of photoionization equilibrium with the extragalactic UV background. The principle results are: (1) the CGM of field L* galaxies exhibits a declining H i surface density with impact parameter

(at

confidence), (2) the transmission of ionizing radiation through CGM gas alone is 70 ± 7%; (3) the metallicity distribution function of the cool CGM is unimodal with a median of

and a 95% interval

to

; the incidence of metal-poor (

) gas is low, implying any such gas discovered along quasar sightlines is typically unrelated to L* galaxies; (4) we find an unexpected increase in gas metallicity with declining

(at

confidence) and, therefore, also with increasing

; the high metallicity at large radii implies early enrichment; and (5) a non-parametric estimate of the cool CGM gas mass is

, which together with new mass estimates for the hot CGM may resolve the galactic missing baryons problem. Future analyses of halo gas should focus on the underlying astrophysics governing the CGM, rather than processes that simply expel the medium from the halo.

Published: March 2017

Recent solar conditions include a prolonged solar minimum (2005–2009) and a solar maximum that has not fully recovered in terms of the Heliospheric Magnetic Field (HMF) strength when compared to the previous maximum values. These anomalies may indicate that we are entering an era of lower solar activity than observed at other times during the space age. We study past solar grand minima, especially the Maunder period (1645–1715) to gain further insight into grand minima. We find the timescale parameters associated with three processes attributed to the magnetic flux balance in the heliosphere using chi-square analysis. We use HMF time series reconstructed based on geomagnetic data and near-Earth spacecraft measurements (OMNI) data to find the fundamental timescales that influence heliospheric field evolution through conversion or opening of magnetic flux from coronal mass ejections (CMEs) into the ambient heliospheric field, removal or loss of the ambient heliospheric field through magnetic reconnection, and interchange reconnection between CME magnetic flux and ambient heliospheric magnetic flux. We also investigate the existence of a floor in the heliospheric magnetic flux, in the absence of CMEs, and show that a floor

nT is sufficient to successfully describe the HMF evolution. The minimum value for the HMF at 1 au in the model-predicted historic record is 3.13 ± 0.35 nT. Our model results favorably reproduce paleocosmic data and near-Earth spacecraft measurements data and show how the HMF may evolve through periods of extremely low activity.
Vom Verschwinden des Autors : Robert Walsers Spuren
Authors: Gisi Lucas Marco
Published: March 2017

Dans son œuvre, Robert Walser se dissimule et se révèle conjointement selon des modalités qui présentent des analogies avec le jeu. Une telle concomitance de la présence et de l’absence se manifeste dans la figure de la disparition, si déterminante dans la réception de Walser. La présente contribution étudie la disparition de Walser en se fondant sur les photographies si célèbres de sa mort ainsi que sur le roman d’Enrique Vila-Matas Docteur Pasavento (2005). En prenant appui sur les théorisations de Michel Foucault et Giorgio Agamben, l’article montre en quoi l’inquiétude de la mort du scripteur s’exprime dans le désir (post-)moderne de voir disparaître l’auteur.
Théodose II, Constantinople et l’Empire : une nouvelle lecture de la Notitia urbis Constantinopolitanae
Authors: Havaux Marie
Published: March 2017

Jusqu’à présent, la Notitia urbis Constantinopolitanae (désormais NuC ) a été étudiée principalement pour ses apports sur la topographie et l’administration de Constantinople dans la première moitié du v e  siècle. Sa rédaction – entre 424 et 427 – se situe pourtant à un moment charnière du règne de Théodose II (408-450). En effet, quelques mois après la mort d’Honorius (423), le primicerius notariorum Jean se proclame Auguste à Rome. Théodose II réagit en lui déclarant la guerre et, après l’avoir élimé, élève son cousin Valentinien au rang d’Auguste pour la partie occidentale de l’Empire. Considérée dans ce contexte, la Notitia apparaît bien plus qu’un document destiné à l’usage de la préfecture urbaine. En effet, le texte comporte un contenu idéologique notable axé sur le statut de Constantinople en tant que capitale de l’Empire romain d’Orient, et sur la glorification de la dynastie théodosienne, et ce, notamment par l’utilisation des topoi du panégyrique de cité. Ainsi, la NuC affirme le rôle central – et désormais prépondérant par rapport à Rome – de Constantinople au sein de l’Empire.
Outcomes at a Minimum of 2 Years After Medial Collateral Ligament Reconstruction Using Partial-Thickness Quadriceps Tendon–Bone Autograft
Authors: Hetsroni Iftach , Mann Gideon
Published: March 2017

This study reports outcomes at a minimum of 2 years after a technique using quadriceps tendon–bone autograft for medial collateral ligament reconstruction. This technique effectively restored medial stability in medial collateral ligament-deficient knees. It is particularly valuable when nonirradiated allograft is unavailable or harvesting medial knee restraints (semitendinosus) for medial collateral ligament reconstruction is to be avoided. [

Evaluation of the Effect of Platelet-Rich Fibrin on Long Bone Healing: An Experimental Rat Model
Authors: Dülgeroglu Turan Cihan , Metineren Hasan
Published: March 2017

Pseudoarthrosis, or nonunion, of the long bones is a challenging medical condition for orthopedic surgeons to treat. Therefore, healing enhancer materials are commonly used. The authors investigated whether platelet-rich fibrin accelerates long bone healing by comparing radiological and histological findings in a rat model of open femoral fracture. Platelet-rich fibrin is a current biomaterial that contains many growth factors and platelets. There are no studies in the literature investigating the effects of platelet-rich fibrin on fracture healing. Sixteen mature male rats were divided into 2 groups. In both groups, an open femoral fracture was created. The platelet-rich fibrin was obtained by centrifuging blood collected from the rats. Rats in the study group were treated with sterile platelet-rich fibrin, and those in the control group were administered saline. The rats were killed at the end of 4 weeks and examined histologically and radiologically. The radiographic and histological scores of the 2 groups differed significantly (
P
<.05). These results indicate that platelet-rich fibrin is an efficient biomaterial in fracture healing and that it increases the amount of osseous tissue formation. Platelet-rich fibrin does not cause an allergic reaction, is cost-effective, and is easy to obtain. Additional studies are necessary to determine whether platelet-rich fibrin accelerates the fracture healing process or induces a better quality of fracture healing. [

Published: March 2017

The implants used in reverse shoulder arthroplasty were originally designed for white patients; thus, they might not be optimal for smaller Asian patients. The selection of reverse shoulder arthroplasty systems is limited in Japan. The purpose of this study was to measure the geometry of the proximal humerus in elderly Japanese patients to inform implant selection according to humerus size. This study included 155 shoulders from 148 patients 50 years or older who underwent computed tomography for shoulder disorders other than arthritis and trauma. There were 67 male and 81 female patients with mean ages of 68 and 66 years, respectively. The humeral head diameter, head height, neck-shaft angle, neck diameters, and osteotomy diameters for 155° inclination implants were measured using surface models created from computed tomography scans. The mean diameter of head curvature, humeral head height, and neck-shaft angle were 48.2 mm, 19.8 mm, and 136° for male patients and 42.4 mm, 17.1 mm, and 136° for female patients, respectively. The mean mediolateral and anteroposterior neck diameters were 46.9 mm and 43.7 mm for men and 41.6 mm and 38.4 mm for women, respectively. The mean mediolateral and anteroposterior osteotomy diameters were 42.2 mm and 41.2 mm for male patients and 38.6 mm and 36.7 mm for female patients, respectively. There were significant differences between the sexes in all measurements except neck-shaft angle. Humeral implants with 155° inclination will not fit the humerus of smaller Japanese women. Thus, implants with anatomical inclination and an onlay humeral tray may be a better choice for smaller patients. [

This study investigated the mechanical properties of a new rectangular compaction blade and compared this blade with other types of nail. Three types of nail were tested: the Magnum lag screw (Robert Reid Inc, Tokyo, Japan), proximal femoral nail, and Magnum Fid blade (Robert Reid Inc). The nails were inserted into solid rigid polyurethane foam, and the torsional moments were loaded with an Instron testing machine (Instron, Kanagawa, Japan). The force curve was recorded, and the average maximum torque was calculated from this curve. A simulation study was performed with finite element models to determine the mechanism underlying differences in rotational stability. Mechanical testing showed that the new compaction blade had stronger resistance against rotational force than the helical blade and lag screw implants. Finite element analysis also showed that the new compaction blade had stronger resistance to migration of the polyurethane foam cylinder than the other implant types. In addition, the new compaction blade had strong rotational stability. This implant should be useful for the treatment of unstable trochanteric fracture in patients with osteoporosis. [

Authors: Alshareef Rayan A. , Khuthaila Mohammed K. , Goud Abhilash , Vupparaboina Kiran Kumar , Jana Soumya , Chhablani Jay
Published: March 2017

BACKGROUND AND OBJECTIVE:

To evaluate subfoveal choroidal vascularity in eyes with myopia in comparison to age-matched healthy subjects.

PATIENTS AND METHODS:

Retrospective analysis of single foveal enhanced depth imaging optical coherence tomography (EDI-OCT) scans of 30 eyes with myopia (axial length greater than 25 mm). Subfoveal choroidal vascularity was evaluated by calculating vessel-area-to-stromal-area ratio using a previously validated automated algorithm.

RESULTS:

The subfoveal stromal area was significantly smaller in myopes (0.95 mm
3
± 0.22 mm
3
) compared to controls (1.33 mm
3
± 0.23 mm
3
;
P
< .0001). However, there was no significant difference in vascular area or in vessel-area-to-stroma-area ratio between the groups (
P
= .15 and
P
= .16, respectively). Subfoveal choroidal vascularity percentage was also not significantly different between the two groups (
P
= .07).

CONCLUSION:

Subfoveal choroidal thinning in myopia is primarily associated with a reduction in choroidal stroma, not vascular components. This needs further exploration and has potential clinical applications.

Le Site André Breton offre aux chercheurs des ressources exceptionnelles sur la constellation surréaliste : par leur nombre, leur variété, leur intérêt. Les documents concernant Aimé Césaire, relatifs à une période allant surtout de 1942 à 1948, sont d’autant plus précieux que le poète martiniquais n’a conservé lui-même que très peu d’archives. Ils révèlent l’art poétique combinatoire de Césaire, à travers la genèse tourmentée du recueil Les Armes miraculeuses, et permettent d’apprécier le lien entre le jeune poète et son aîné, en exil dans le Nouveau Monde.
A Unified Framework of Organizational Perspectives and Knowledge Management and Their Impact on Job Performance
Authors: Kasemsap Kijpokin
Published: March 2017

This chapter introduces the framework and causal model of organizational culture, organizational climate, knowledge management, and job performance related to business process orientation. It argues that dimensions of organizational culture, organizational climate, and knowledge management have mediated positive effect on job performance. Knowledge management positively mediates the relationships between organizational culture and job performance and between organizational climate and job performance. Organizational culture is positively related to organizational climate. Furthermore, the author hopes that understanding the theoretical constructs of organizational culture, organizational climate, knowledge management, and job performance through the use of the framework and causal model will not only inform researchers of a better design for studying organizational culture, organizational climate, knowledge management, and job performance, but also assist in the understanding of intricate relationships between different factors.

Authors: Studdard Nareatha , Dawson Maurice , Burton Sharon L. , Jackson Naporshia , Leonard Brian , Quisenberry William , Rahim Emad
Published: March 2017

For the development of social entrepreneurs it is imperative that educators embrace the concepts and process of social entrepreneurship (Dees, 1998). Exploration of these concepts in education could prove beneficial to the community (Haugh, 2005). This chapter focuses on the positives of introducing social entrepreneurship education at the primary and secondary levels of education. Specifically, its central focus deals with building children's entrepreneurial self-efficacy at a young age. Several benefits, of increasing self-efficacy at a young age, are outlined. Benefits, such as entrepreneurship training, not only training students, but it helps to prepare them for the new knowledge-based economy. Further, entrepreneurship education should help increase the success and survival rates of women and minority entrepreneurs. Essential to this process, a new curriculum needs to be devised including its means of assessment. Lastly barriers to an entrepreneurship program are discussed; this includes financial, legal, political and negative perceptions of entrepreneurship education.

Published: March 2017

This chapter examines the role of entrepreneurship and innovation in the development of family businesses in Latin America. The socio-economic dynamics of such region is an interesting field for research, mainly because: it is a major manufacturing hub with growing importance in retail; it experienced a huge economical shift in the last ten years causing the growth of the middle class (an increase of 50 million people); family firms in the region are the main driver of growth and employment. The authors focused the analysis on Mexico due to its singular characteristics, making it a representative example of the region. Based on secondary sources, a characterization of the entrepreneurship and innovation in family owned and managed firms in the region is reviewed. Moreover, based on the Global Entrepreneurship Monitor database, the authors present some recent data related with entrepreneurship levels in the region and its impact in terms of innovation. Finally, public policy implications are provided in order to encourage entrepreneurship and innovation in family businesses.

Worry and anger rumination in fibromyalgia syndrome
Authors: Ricci A. , Bonini S. , Continanza M. , Turano M.T. , Puliti E.M. , Finocchietti A. , Bertolucci D.
Published: March 2017

The aim of the present study was twofold: 1) to investigate the psychological profile of patients with fibromyalgia syndrome (FS) as compared to patients with other chronic pain syndromes (CP) and healthy subjects (HS); 2) to examine the associations between anxiety, depression, worry and angry rumination in FS patients. FS patients (N=30), CP patients (N=30) and HS (N=30) completed measurements of anxiety, depression, worry and angry rumination. FS patients showed higher levels of state and trait anxiety, worry and angry rumination than CP patients and HS, and higher levels of depression than HS. Worry and angry rumination were strongly associated in the FS group. FS patients may use worry and rumination as coping strategies to deal with their negative emotional experience, which might impair their emotional wellbeing. Findings from the present study add to our understanding of the psychological profile of FS patients, and have important implications for developing a tailored CBT protocol for pain management in FS patients.
Oxygen and carbon isotope studies of hydrothermal alteration in the Troodos Ophiolite complex, Cyprus
Authors: Vibetti N J , Kerrich R , Fyfe W S
Published: March 2017

Oxygen isotopic analyses of samples from the sheeted complex and gabbroic sequence of the Troodos ophiolite complex show that subsolidus hydrothermal oxygen isotope exchange with seawater occurred throughout the sheeted complex, high level gabbros and locally
even penetrated down into the layered gabbros and ultramafic rocks. Sheeted dykes and high level gabbros show variable depletions (0 180 = 2.2 to 4.6) whereas deeper level altered gabbros are variably depleted or enriched (0 180 = 1.1 to 10.4) relative to fresh oceanic basalts. The enrichments at
depth in the gabbros are in part due to exchange at much lower temperatures with isotopically evolved seawater than has occurred with the overlying rocks. Late stage calcite bearing vein assemblages show a variable depletion (o13C = -9.7 to -15.7) indicative of the presence of some dissolved
biogenic carbon during the waning stage of fluid circulation through the uppermost parts of the ophiolite.
Magnetic properties of an analog of the lower oceanic crust: magnetic logging and paleomagnetic measurements from drill hole CY-4 in the Troodos Ophiolite
Authors: Pariso J E , Johnson H P
Published: March 2017

Analysis of magnetic logging and paleomagnetic results show that there are five distinct magnetic zones within the lower crustal intrusive rocks drilled at site CY-4. These zones are defined by both the lithology and alteration of the drilled section. The upper
zone, A, is composed of altered diabase dikes which exhibit a relatively high natural remanent magnetization (1 0 ) and magnetic susceptibility (k). Zone B dikes are characterized by the highest J0 and k within CY-4, a large amount of scatter in 10 and ls, and the least stable magnetization within
the section. Lithologically, zone C is the transition between sheeted dikes and gabbros. The dikes within this zone have magnetic properties similar to those of zone A dikes, while the gabbros are characterized by low k and moderate J0 Additionally, the dikes bear components of secondary
magnetization which cause a great deal of scatter in NRM directions. Zone D is composed solely of gabbro which have the lowest observed J0 and k within CY-4. Finally, zone E is composed of interlayered gabbro and ultramafic units. The higher J0 and k observed within this zone is caused by formation
of secondary magnetite during serpentinization.
Geophysical structure of the Troodos Ophiolite from downhole logging
Authors: Salisbury M H , Christensen N I , Vine F J , Smith G C , Eleftheriou S
Published: March 2017

Velocity (Vp and Vs), density, porosity, natural gamma, resistivity , total magnetic field and magnetic susceptibility logs demonstrate that the Troodos ophiolite complex is geophysically similar to the oceanic crust. Insitu velocities (Vp) range from 3.2-3.5
km/s in the pillow basalts (Layer 2A) and then increase gradually through the pillow basalt/dike transition and the sheeted dikes (Layer 2B) to classic Layer 3 velocities (6.7-6.9 km/s) in the gabbros while Vs averages 2.1 km/sin the pillow basalts and rises to values of 3.2-3 .5 km/s in the
gabbros. In the pyroxenites, Vp increases only slightly (to 7.0 km/s) but Vs rises to 4.0 km/s. The porosity and natural gamma radiation decrease from averages of 20% and 30 API units, respectively, in the pillow basalts to negligible values in the gabbros, while the formation density and
resistivity increase from 2.2 to 2.95 g/cm3 and from I 0 to 20K-50K ohm-mover the same interval, suggesting that seawater penetrates no deeper than the base of the dikes. Aside from Ys, the only property which changes at the gabbro/pyroxenite boundary is density, which increases abruptly to 3.1
g/cm3 The magnetic susceptibility increases steadily from 0.5 x 10-3 S.I. units in the pillow basalts to 4 x 10-3 units at the 50% dike/50% gabbro transition, below which it decreases abruptly to 0.5 x 10-3 units. Since resistivity increases by an order of magnitude at the same depth and Vp
increases rapidly from 5.75 to 6.4 km/s at this depth and then increases steadily to 6.8 km/s within the next few hundred meters, we interpret the dike/gabbro transition as the Layer 2/3 boundary of the oceanic crust.
Velocity structure of the Troodos massif, an arc-derived Ophiolite
Authors: Christensen N I , Salisbury M H
Published: March 2017

The seismic velocity structure of a section of the Troodos Massif has been reconstructed in detail from values of compressional (Vp) and shear (Vs) wave velocities measured in the laboratory under elevated hydrostatic confining pressures for 74 samples obtained
from drillhole CY-4 at Palekhori, Cyprus. The 2263 m thick section begins in sheeted dikes and continues through a gabbroic section into ultramafic rocks consisting of websterites, olivine websterites and minor lherzolites. The sheeted dike section shows strong velocity gradients with Vp increasing
from 5.4 km/sec at the top to 6.8 km/sec at 630 m depth. Beneath the dike section, low velocity zones for both Vp and Vs originate from alteration of high level gabbros. Velocities from depths between 950 m and 1750 m agree well with oceanic Layer 3 velocities. The transition from gabbro to
websterite and olivine websterite at 1750 m marks a sharp increase in velocity to Vs = 4.2 km/sec and Vp = 7.7 km/sec. These values fall within the range observed for the oceanic Mohorovicic discontinuity by refraction.

As a contribution to the Slave Province NATMAP, Terrain Sciences mapped three 1:250000 map areas (NTS 86A, 76D, and 76C) in the Lac de Gras area with the objective of providing a regional framework for geological interpretation and drift prospecting. This report
documents the preliminary results from the first field season. Till is the most common surficial sediment and only one till sheet was identified. This till sheet represents several different directions of transport, including southwest, west, and northwest. Three broad zones of dominant flow were
defined throughout the area, each requiring a different approach for drift prospecting. As well, glacial transport distances were evaluated, based on the lithology of pebbles in the till which indicated both local and distant transport.
The Shaler Supergroup and revision of Neoproterozoic stratigraphy in Amundsen Basin, Northwest Territories
Authors: Rainbird R H , Jefferson C W , Hildebrand R S , Worth J K
Published: March 2017

Elevation of the Shaler Group to supergroup status and the following internal revisions are proposed in order to more properly reflect rock units of the Amundsen Basin. The names Escape Rapids, Mikkelsen Islands, Nelson Head and Aok are proposed to replace the
lower clastic, cherty carbonate, upper clastic, and orange-weathering stromatolite members of the Glenelg Formation in Minto and Cape Lambton inliers, informal map units 19 to 21, 22, 23, and 24 in the Coppermine area and informal map units P1, P2, P3, and P4a in Brock Inlier, respectively.
Collectively these are to be known as the Rae Group; the name Glenelg Formation is abandoned. The former Reynolds Point Formation is raised to group status and comprises the Grassy Bay, Boot Inlet, Fort Collinson and Jago Bay formations, which replace the lower clastic, lower carbonate, upper
clastic and upper carbonate members in Minto Inlier and informal map units P4b, P4c, lower P4d and upper P4d in Brock Inlier, respectively.
Geology of the Wijinnedi Lake area-a Paleoproterozoic(?) asymmetric uplift of Archean rocks in the southwestern Slave Province, District of Mackenzie, Northwest Territories
Authors: Henderson J B
Published: March 2017

The area occurs at the north end of an 80 km long uplift bounded by a north-trending low-grade cataclastic shear zone exposing Archean low, high grade and ultimately granulite grade rocks in a series of mylonite separated domains. A large, deformed, dacitic
volcanic breccia dome mantled by a relatively minor unit of mafic volcanic rocks occurs in the lowest grade Wijinnedi domain. It is intruded by a gabbro to anorthositic gabbro intrusion of a type known elsewhere in the Slave Province to be synvolcanic, and at one locality by a greenschist-grade,
deformed diatreme containing abundant, very coarse garnet pseudomorphs. The rocks of the highest grade Ghost domain occur in an asymmetric antiform in which the rocks of the lower grade limb are more deformed than those of the higher grade limb where some granulite grade granitoid plutons are
unfoliated. The antiformal axis is cored by large, coarsely megacrystic, granite plutons.
Till composition in the vicinity of the Manitouwadge greenstone belt, Ontario
Authors: Kettles I M , Murton J B
Published: March 2017

In 1991 and 1992, 286 till samples were collected for mineral exploration purposes in the vicinity of the Manitouwadge greenstone belt. Samples were analyzed for their content of clasts of distinctive Precambrian and Paleozoic lithologies and for trace elements
in the <.002mm fraction. Variation in till composition can be related to glacial transport and local bedrock geology. In many areas, the till contains abundant Paleozoic carbonate clasts glacially transported southwestward from the Hudson Bay and James Bay lowlands. Where present in large
quantities, Paleozoic carbonate tends to suppress the geochemical signature of till partially derived from local Precambrian bedrock, which contains higher trace element levels. Despite the effects of dilution, anomalously high concentrations of Cu, Pb, and Zn are found in till overlying and
immediately down ice from the Geco and associated VMS deposits at Manitouwadge and, elsewhere, at a few sites overlying and away from the greenstone belt.
Acoustic velocity logging at the McConnell nickel deposit, Sudbury area, Ontario: preliminary in situ measurements
Authors: Pflug K A , Killeen P G , Mwenifumbo C J
Published: March 2017

An acoustic velocity logging probe has been used to acquire data on the seismic characteristics of the McConnell nickel deposit in the Sudbury area. Preliminary results indicate good velocity contrasts in the stratigraphic sequence associated with the massive
sulphides. These velocity contrasts are related to the density and elastic properties of the rocks; density was measured in the same borehole with a density logging probe. One interesting observation is that the high density massive sulphides have low P-wave velocities relative to the host rocks.
This is not a universally applicable condition because some massive sulphides in other areas being investigated have higher velocities. Full sonic waveforms were recorded and these will be further studied to extract S-wave velocities. The P- and S-wave velocity and amplitude logs will then be used
to derive valuable geotechnical information.
Partie I: analyse géologique des zones gazéifères et évaluation des ressources

Natural gas resource potential of Triassic strata in the Western Canada Sedimentary Basin (excluding the Foothills Belt) was evaluated using a combination of geological play analysis and statistical estimation. Triassic strata belong to a platformal succession of
mixed siliciclastic, carbonate, and evaporite sediments deposited along the western portions of the basin. The thickest deposits, and most of the oil and gas, occur in the westward thickening and deepening depocentre called the Peace River Embayment. The Triassic succession contains a total
discovered in-place volume of 288 400 x 106m3 raw gas reserves in 10 mature and 2 immature plays. Exploration plays consist of stratigraphic and stratigraphicþstructural combination traps, with reservoirs in aeolian, shoreline, tidal channel, and shallow marine sandstones, coquinas, and tidal flat
and marine shelf carbonates. Statistical analysis of the ten established mature plays suggests they contain a remaining potential of 272 124 x 106m3. Three of these plays are predicted to contain over one half of the remaining gas potential: the Halfway/Doig Formation shelf sandstones play,
influenced by Peace River Arch/Embayment structures (e.g., Monias field); the Baldonnel Formation subcrop play, involved in Laramideþaged gentle folds (e.g., Laprise field); and the Halfway/Doig Formation shoreline-related sandstone reservoirs, influenced by Peace River Arch/Embayment structures
(e.g., Sinclair field). Statistical analysis of the mature plays indicates that a total of 13 plays are likely to exist. These include the 10 mature plays, 2 immature plays (the Montney Subcrop NorthþRing play and the Montney Distal Shelfþ Glacier play) with undiscovered gas in-place totalling 28
162 x 106m3, and 1 conceptual play with 5 615 x 106m3 gas in-place. The relatively minor amount of gas estimated to be present in the conceptual and immature plays (33 777 x 106m3þ11% of the total resource) is consistent with the exploration maturity of the basin and the fact that established
play definitions are sufficiently broad to include variations in trapping mechanism. Expected potential in-place gas volumes in mature, immature and conceptual plays (unencumbered by economic constraints) total 305 901 x 106m3, indicating that over 50 per cent of the total in-place resource remains
to be discovered. Triassic strata continue to offer attractive exploration targets, as shown by recent activity at Valhalla, Spirit River and Grande Prairie.
Séquence des écoulements glaciaires dans le secteur de Chibougamau-Némiscau, Québec
Authors: Paradis S J , Boisvert E
Published: March 2017

A survey of glacial erosion indicators in the area between Chibougamau and Nemiscau has revealed the presence of ancient ice-flow indicators in a west-northwesterly direction as far as the Dompierre and Villebois lakes sector, 50 km north of Chibougamau. These
new observations indicate a possible ice divide in the Matagami-Chibougamau-Nemiscau region. This ancient movement to the west-northwest suggests a new interpretation of the ice-flow sequences: an initial glacial movement to the west-northwest, followed, in the area south of Broadback River, by a
glacial movement toward the southeast, which could be linked to the formation of an ice divide located somewhere north of Nemiscau. This phase was followed by a final regional movement in a southwesterly direction which is present in the entire study area.
Seismograms for historic Canadian earthquakes: the 5 June 1940 Richardson Mountains, Yukon earthquake
Authors: Bent A L , Cassidy J F
Published: March 2017

This paper is one in a series of reports designed to catalog the Geological Survey of Canada's (GSC) collection of seismograms for historical Canadian earthquakes. The data set has been assembled by past and present seismologists at the GSC. The seismogram
collection for the 5 June 1940 Richardson Mountains earthquake consists of 94 records from 37 seismograph stations. Of these, 69 seismograms from 25 stations have been digitized. To assist those who may study this earthquake in the future, this report describes the seismograms in the collection and
indicates which record segments have been digitized. The digital data files may be obtained from the GSC. We also summarize magnitude calculations and first motion polarities for all stations utilized in the detailed study of this earthquake
by Cassidy and B eni [1993].
Sedimentary processes and surficial geology of the Pacific margin of the Queen Charlotte Islands, British Columbia
Authors: Barrie J V , Conway K W
Published: March 2017

The active Pacific margin of the Queen Charlotte Islands has been subject to vigourous wave and tidal energy since glacial times resulting in a continental shelf and coastal zone that are almost devoid of sediment. After minimal glaciation of the narrow shelf,
the region became emergent with sea level lowering of up to, and possibly greater, than 200 m due to a glacio-isostatic forebulge ending near 10 400BP (14C date) followed by a rapid transgression that reached approximately 15 m above present sea level. This transgression effectively removed all
unconsolidated sediment along the coast except in a few protected basins, such as Rennell Sound.
Mapping Pleistocene deposits beneath the Fraser River delta: preliminary geological and geophysical results
Authors: Luternauer J L , Hunter J A
Published: March 2017

Direct sampling, chronological analysis, and remote geophysical techniques have identified Pleistocene deposits beneath the Fraser River delta sediments. Relief on the surface of documented Pleistocene deposits is high; depth beneath ground surface to these
deposits ranges from 8 to 305 m. Known Pleistocene sequences are highly variable in grain size but gravel, diamicton, or till constitute <20% of the total deposits. Pronounced changes in geophysical properties are associated with the Holocene-Pleistocene boundary. Information acquired
to date emphasizes the complexity of the region's geological architecture and suggests that a map of subsurface Pleistocene deposits will contribute to geotechnical assessments of local earthquake hazards.
Conodont biostratigraphy of the Driftpile stratiform Ba-Zn-Pb deposit, Gataga district, northeastern British Columbia
Authors: Paradis S , Nelson J L , Irwin S E B
Published: March 2017

The Driftpile deposit is hosted by fine-grained siliciclastic rocks of the Upper Devonian Gunsteel formation, in a series of imbricate northeastward-verging thrust panels. Mineralized units consist of two facies - localized pyrite (±sphalerite, galena), and
laterally extensive barite-pyrite (±sphalerite, galena) facies. Both have a siliceous, poorly bedded, locally radiolarian-bearing shale/mudstone footwall and a concretionary and nodular shale/mudstone turbidite hanging wall.

Conodont biostratigraphy indicates that all mineralized units are mid-Famennian. The pyrite (±sphalerite, galena) unit of the "Main Zone" is trachytera Zone, the barite-pyrite (±sphalerite, galena) unit of the "East Zone" is early Upper marginifera, and the mineralized unit of the "North
Trench Zone" is Lower marginifera Zone. The Driftpile deposit thus comprises several distinct sulphide (±barite) lenses. Centres of exhalative activity shifted from sub-basin to sub-basin through mid-Famennian time. The present deposit morphology is due to Jura-Cretaceous
thrusting.
The Duke of York and related Neoproterozoic inliers of southern Victoria Island, Distict of Franklin, Northwest Territories
Authors: Rainbird R H , LeCheminant A N , Lawyer J I
Published: March 2017

Duke of York inlier contains a ~400 m-thick succession of sulphate evaporite, cherty dolostone, and siltstone-quartz arenite of the Neoproterozoic Shaler Supergroup. When linked with similar rocks to the north and south, these strata define a broad, gently
northwest-dipping and northwest-concave arc. The arc parallels the inferred erosional edge of an intracratonic basin formed on the northwestern margin of Laurentia. The sedimentary rocks are intercalated with at least six gabbro sills, up to 125 m thick, intruded during a large magmatic outburst at
0.72 Ga (Franklin events) linked to break-up of a Neoproterozoic supercontinent. The intrusive suite also includes northwest-striking dykes and variably dipping, irregular gabbro sheets. A northeast-striking fault separates Victoria Island outcrops from down-dropped strata on the Richardson Islands.
Proterozoic rocks are overlain by lower Paleozoic marine sandstones and carbonates, which can be correlated with the Old Fort Island and Cass Fiord formations, respectively.
