Vienna international airport noise abatement
Authors: Jelinek-Nigitz Heidelinde
Published: March 2016

Purpose: On the topic of sustainable aviation a study was carried out to measure the difference between the actual change in air traffic noise and the airport’s residents’ perception of the noise change at Vienna International Airport. Therefore, a questionnaire was developed in cooperation with the airport and an online survey was conducted.Design/methodology/approach: For the survey of the opinion of the affected population of the surrounding communities, a web based online questionnaire is created and distributed via various channels including e-mail, and online forums. After the basic structure of the questionnaire had been defined, the questions were developed in cooperation with employees form the environmental department of VIE, who had a sustainable influence on the questions’ order and formulation. As the survey was supposed to be answered by residents around VIE.Findings: Results of the online study show that only parts of the participants are affected by air traffic noise at VIE. Even less experienced a significant change over the last five years. About one third of the participants stated that they are affected by air traffic noise in one way or another. The majority of these people live in Lower Austria, the federal state in which the airport is located. The participants obviously judge air traffic noise during day time more importantly than air traffic noise at night.Research limitations/implications: Due to the low number of returns, no statistically relevant conclusions can be drawn, the results of the survey can be used to make some general statements.Originality/value: Economic growth and deregulation lead to growing aircraft operations. Vienna International Airport with its approximately 260,000 flight movements per year is the biggest airport in Austria and a major hub in Europe. The combination of constantly growing air transport and the resulting noise exposure, as well as the steadily increasing sensitization of the population, bring the issue of aircraft noise emission into the increased interest of the stakeholder of an airport. The study compares the extent of the subjective perceived and the actual noise emissions’ change over the last years.
Versions of Homer: Translation, fan fiction, and other transformative rewriting
Authors: Farley Shannon K.
Published: March 2016

This article posits a paradigm of transformative work that includes translation, adaptation, and fan fiction using the Homeric epics as a case study. A chronological discussion of translations, other literary rewritings, and fan fiction distinguishes each as belonging to its respective cultural system while participating in a common form of transformative rewriting. Such a close look at the distinctive ways that Homer has been rewritten throughout history helps us to make a scholarly distinction between the work of fan writers and the work of rewriters like Vergil and Alexander Pope. At the same time, discussing the ways in which the forms of their rewritings are similar gives a scholarly basis for arguing that fan fiction participates in the discourse of serious interpretive literature.

À la recherche du substrat cognitif du submorphème SM-
Authors: Argoud Line
Published: March 2016

The overall objective of this study is to find traces in the English lexicon of a notional invariance attached to a formal invariance, possibly dating back to a very early stage of the language. In the English lexicon, I explore the class of lexical items beginning with sm-. From the definitions of ‘sm- words’ attested in the Oxford English Dictionary and the English Dialect Dictionary, I shall endeavour to show that the phonological invariance of this heuristically-formed class corresponds to a submorphemic invariance which may be traced back to a very ancient process of conceptualization of the human body. Drawing on various approaches of cognitive linguistics (Lakoff & Johnson, Langacker, Heine, Sweetser), I suggest a description of the way the brain conceptualizes the referents of ‘sm- words’, and I shall show the convergence with the etymological data.Ultimately, I claim that the meanings of most ‘sm- words’ access mental representations relating on the one hand to experiential information collected by the nose and/or the mouth, and on the other hand to physical expressions of emotions through movements or positions of these two body parts. Special emphasis will be laid on the duality prevailing in several fields: two-way movements between the object and the subject of perception (smoke, smother, smoulder, smell); relations between the ‘in-movement’ of impressions or sensations (smell, smooth, smutty) and the ‘out-movement’ of the expression of emotions (smile, smirk, smug); overlap between features pertaining to the senses of smell / taste, and touch (smack, smart, smear, smite).
Norm-blindness and its effects on utterer-centred practice
Authors: Walker Jim
Published: March 2016

Le présent article se propose de remettre en question la notion de valeur centrale dans les théories françaises de l’énonciation en démontrant que ces théories sous-estiment quelque peu l’importance des variétés de l’anglais et l’influence de la tradition prescriptiviste, et en prétendant qu’in fine l’énonciation est vouée à l’échec si elle ne sait pas se colleter avec cette réalité. A travers trois exemples (les modaux WILL/SHALL ; l’alternance entre if I was / if I were ; HAVE+-EN et le renvoi au révolu), l’auteur souligne que bien souvent les énonciativistes développent des hypothèses en l’absence de toute référence autre qu’à l’anglais britannique standard, et sur la base de corpora qui sont issus d’œuvres littéraires qui ne reflètent guère la langue dans ce qu’elle a de vivant. Cette approche, nécessairement lacunaire, a pour conséquences soit que certaines constructions grammaticales ne peuvent être saisies dans leur totalité, soit qu’elles ne parviennent pas à se frayer un chemin jusqu’aux textes les plus importants.
« Procédure bâillon » : Retour sur l'affaire des sondages de l'Elysée et la liberté d'expression des universitaires
Authors: Mercier Jérémy
Published: March 2016

Après avoir été poursuivi pour diffamation par Patrick Buisson, ex-conseiller du président Nicolas Sarkozy, dans l'affaire des sondages de l'Elysée, l'universitaire Alain Garrigou était assigné en justice par Fiducial, la première entreprise française de conseil fiscal, et son dirigeant, Christian Latouche, pour avoir notamment signalé que celui-ci avait des « affinités idéologiques avec l’extrême droite ». Tandis que la 17ème Chambre du Tribunal de Grande Instance de Paris jugea qu'une telle plainte était abusive et constituait une « procédure bâillon » visant à intimider et faire taire toute critique, la Cour d'Appel a rejeté ce moyen. Pot de terre contre pot de fer ? Une telle interprétation pose la question décisive de l'avenir de la liberté d'expression face aux intérêts politico-financiers pouvant, surtout en période électorale, donner lieu à des plaintes abusives. Les juges judiciaires n'auraient-il pas intérêt à se munir, en plus du législateur, d'une jurisprudence « anti-procédure bâillon » dite anti-slapp, permettant d'éviter de telles intimidations sur les auteurs de propos d'intérêt général pour la démocratie ?
Influence of Control Coupling Effect on Landing Performance of Flying Wing Aircraft
Authors: Hong Wei Jiang , Ma Dong Li
Published: March 2016

As flying wing aircraft has no tail and adopts blended-wing-body design, most of flying wing aircrafts are directional unstable. Pitching moment couples seriously with rolling and yawing moment when control surfaces are deflected, bringing insecurity to landing stage. Numerical simulation method and semi-empirical equation estimate method were combined to obtain a high aspect ratio flying wing aircraft’s aerodynamic coefficients. Modeling and simulation of landing stage were established by MATLAB/Simulink. The control coupling effect on lift and drag characteristics and anti-crosswind landing capability was studied. The calculation results show that when the high aspect ratio flying wing aircraft was falling into the deceleration phase, appropriate to increase the opening angle of split drag rudder can reduce the trimming pitching moment deflection of pitch flap, thereby reduce the loss of lift caused by the deflection of pitch flaps. Flying wing aircraft can be rounded out successfully by using the pitch flap gently and steady. Both side-slip method and crabbed method can be applied to the landing of high aspect ratio flying wing aircraft in crosswind, the flying wing aircraft’s anti-crosswind landing capability was weakened by the control coupling effect of split drag rudder and elevon. Sideslip method was recommended in the crosswind landing of flying wing aircraft after calculation and analysis.

Authors: Torabi Asr Mahdi , Osloob Reza , Mustapha Faizal
Published: March 2016

H-Darrieus wind turbines, due to their simple design and relatively low manufacturing costs have recently received much attention particularly for standalone applications. However start-up issues associated with their operation restricted their operation in areas of low average wind speed and encourages engineers to develop novel design. Several design proposed in this way but in most cases design came up with complex sensing mechanisms and mechanical actuators or high cost manufacturing parts. A recent rotor design called double Darrieus rotor proposed as a German patent case bridged these complexities appropriately. The aim of present study is to investigate this innovative design from aerodynamic point of view by means of validated CFD techniques. A flow-driven simulation setup based on 6DOF calculations employed in order to study rotor operation from stand still until peak performance obtained. Results from these precise modeling reveal the superiority of the proposed double-stage design in compare with the original H-Darrieus rotors in terms of start-up behavior and optimum performance.

Authors: Salah Faisal , Viswanathan K.K. , Aziz Z.A.
Published: March 2016

The effects of stimulated g-jitter which come together with heat and mass transfer by mixed convection in microgravity situation on MHD flow of Oldroyd - B fluid in porous space is investigated for a particular system. The system comprises of a pair of heated up perpendicular parallel infinite plates maintained at constant although various concentrations and temperatures. By using modified Darcy’s law, the equations governing the flow are modelled. These equations are solved exactly for the distributions of stimulated velocity, temperature and concentration. Interestingly the solutions for second grade and Maxwell fluids are recovered as new limiting cases of the present general results. Similar result in the relevant literature relating to Newtonian fluid is also obtained as a special case of the present solution. Finally particular attention is given to the graphical results for the velocity profiles of the oscillating flow in the channel. The analysis on the variations of embedded flow parameters in the solution expressions are presented and discussed.
Modeling Analysis of Contactless Power Transfer System for Rotary Ultrasonic Machining
Authors: Wang Xin Wei , Wang Ai Min , Wang Xiao Long
Published: March 2016

In rotary ultrasonic machining (RUM), the traditional power transfer method was achieved by slip ring that cannot cope with high-speed rotary of the tool, which limits the machine potential of RUM. Based on the principle of electromagnetic mutual inductance and the technology of loosely coupled inductively power transfer (LCIPT), a contactless power transfer system (rotary transformer) is built for RUM to achieve its power transfer goal. Resonant Compensation technology is used to enhance the efficiency of the rotary transformer. And the performance of the rotary transformer is validated on Maxwell platform.
Fatigue Crack Growth Simulations in Ductile Materials by Coupled FE-EFG Approach
Authors: Kumar Sachin , Singh Indra Vir , Mishra B.K.
Published: March 2016

In this paper, a coupled finite element (FE) and element free Galerkin (EFG) approach is presented for the simulation of fatigue crack growth problems. The problem domain is subdivided into two regions i.e. EFG region and FE region. A ramp function is used in the transition region to obtain the resultant shape functions. This approach effectively handles the crack growth problems without remeshing, and is found computationally more efficient than other meshfree methods. The effectiveness of this approach is demonstrated by simulating material interface fatigue crack growth problems. These simulations show that the results obtained by coupled approach are in good agreement with the XFEM results.

Published: March 2016

This computational study is aimed at studying the effects of flap deflection angle on aerodynamic coefficients of NACA 2412 airfoil and thus predicting the suitability of using the airfoil with flap at various phases of flight. The change in airflow over the airfoil at different angles of attack (0, 4, 8 and 12 degrees) and at different flap deflections give a clear understanding for the use of right combination of these two parameters. A full package of pictorial description for visualizing the changes in flow with and without the flap is provided through pressure and velocity contours.
Variable Cross-Section Thin-Walled Composite Structure Modeling Based on the Super-Element Method
Authors: Xia J. , Wang Zhi Jin , Kretov A.S.
Published: March 2016

For slender structures (for example larger aspect ratio wing or fuselage), when they are under loads, the in-plane cross-section shape of these structures remains unchanged. Using this feature, in this paper, a new method called super-element method (SEM) is proposed with the hypothesis of in-plane rigidity. The stiffness matrix of one super-element which has reduced degrees of freedom compared with FEM is derived and they are assembled together to get the stiffness matrix of whole structure. Then through the boundary conditions, the stress and displacement distribution can be calculated out. Calculation analysis of three examples reveals the validity and feasibility of super-element method.

Authors: de S. Lima Bruna C. , de Araújo Ofélia Queiroz Fernandes , de Medeiros José Luiz , Morgado Cláudia R.V.
Published: March 2016

The recent discoveries of Pre-Salt layers in Brazil require process developments for enhanced sustainability as these reservoirs have oil with associated natural gas exhibiting an expressive amount of CO2 [1,2]. The challenge is thus to expand the supply of this fossil raw material to produce energy and chemicals in a carbon-constrained economy. In this scenario, CO2 capture and reuse techniques are important routes for a moderate transition from the present fossil-based economy to a long-term sustainable future. This work evaluates two process alternatives for a floating unit consisting of physical absorption of CO2 from natural gas, with propylene carbonate, producing a natural gas stream poor in CO2 and a stream consisting of a mixture of CO2 and hydrocarbons. Two alternatives are evaluated for processing the CO2 rich stream to yield methanol. Technical, economic and environmental analyses of the process flowsheets are performed for comparison purposes. Alternative 1 combines dry and steam reforming in one reactor (one pot reactor, Bi-Reforming), while Alternative 2 segregates the two reactions: dry reforming (Dry-Reforming) occurs in one reactor and water gas-shift reaction takes place in a subsequent reactor. The two Alternatives are evaluated with ASPEN HYSYS® (ASPENTECH Inc) simulator for calculation of energy and mass balances necessary to assess economic and environment performances. The economic evaluation employed the software Capital Cost Estimation (CAPCOST) for calculations of CAPEX and OPEX. The software Waste Reduction Algorithm (WAR, EPA) was used to evaluate the potential environmental impacts, by PEI (Potential Environmental Impact). Results indicate that the performance of Alternative 1 was better than Alternative 2: (a) methanol production (17905 kg/h) 4 times higher, (b) CAPEX (U$$75.497.127), 21,7% lower, (c) Sales Revenue (U$$144,890,686) 181% greater, and (d) the index for environment impact (868 PEI/hr) 47,7% lower.

Published: March 2016

Cement industry has always been among the largest industrial CO2 emission sources, accounting for 7% of global CO2 emission from stationary sources. CCS technology appears as a major option, in addition to fuel saving and fuel switching measures, able to mitigate CO2 emissions. This study evaluates the potential application of carbon capture in the Brazilian cement sector. Among the CO2 capture technologies studied, the only commercially available for the existing cement plants in Brazil is based on the post-combustion capture route, relying on chemical absorption. To calculate the potential of retroffiting Brazilian cement facilities, it was assumed that the steam and power needed by the capture plant would be generated from a cogeneration plant with natural gas or petroleum coke, or a petroleum coke boiler or even a natural gas boiler would generate steam, and power would be purchased from the grid. Findings indicated an abatement cost hovering between $ 114/tCO2 (in Southeast, South and Midwest of Brazil) and $ 117/tCO2 (in North and Northeast). The gross potential equaled 47 MtCO2/year, being reduced to 31 MtCO2/year after discounting the fraction withouth water availability to implement a carbon capture facility.

Published: March 2016

The performance of SAE 1010, API K55 and API N80 steels were evaluated in terms of resistance to corrosion with the use of two CO2-saturated saline solutions (NaCl and CaCl2, both at the concentration of 0.5 M) and wet supercritical CO2 at a temperature of 90°C under 15 MPa for 07 days. Mass loss tests were performed to determine corrosion rates and the films of corrosion product evaluated by scanning electron microscopy and potentiodynamic polarization technique. Lower corrosion rates were obtained in a wet supercritical CO2 medium. The degree of protection offered by corrosion products films depended not only on the steel but also on the corrosive medium and kind of salt present.
Platelet-Derived Growth Factor Receptor Activation Promotes the Prodestructive Invadosome-Forming Phenotype of Synoviocytes from Patients with Rheumatoid Arthritis
Authors: Charbonneau Martine , Lavoie Roxane R. , Lauzier Annie , Harper Kelly , McDonald Patrick P. , Dubois Claire M.
Published: March 2016

Fibroblast-like synoviocytes (FLS) play a major role in invasive joint destruction in rheumatoid arthritis (RA). This prodestructive phenotype has been shown to involve autocrine TGF-β that triggers formation of matrix-degrading invadosomes through molecular mechanisms that are not fully elucidated. The platelet-derived growth factor (PDGF) receptor (PDGFR) family of receptor tyrosine kinases (RTK) has been shown to cooperate with TGF-β in various pathological conditions. We therefore sought to determine whether RTK activity played a role in invadosome biogenesis. We demonstrated that, among the common RTKs, PDGFR-αβ was specifically phosphorylated in FLS from RA patients. Phosphorylation of PDGFR-αβ was also elevated in RA synovial tissues. Interference with PDGFR activation or PDGF neutralization inhibited invadosome formation in RA synoviocytes, indicating the presence of an autocrine PDGFR activation loop that involved endogenous PDGF. Among the PDGF-A–D isoforms, only PDGF-B was found both significantly elevated in FLS lines from RA patients, and related to high-invadosome forming cells. Addition of TGF-β upregulated invadosome formation, PDGF-B mRNA expression, and phosphorylation of PDGFR. All of these functions were efficiently suppressed by TGF-β neutralization or interference with the Smad/TβR1or PI3K/Akt pathway. Among the class 1 PI3K family proteins known to be expressed in RA synoviocytes, PI3Kα was selectively involved in PDGF-B expression, whereas both PI3Kα and PI3Kδ participated in invadosome formation. Our findings demonstrate that PDGFR is a critical RTK required for the prodestructive phenotype of RA synovial cells. They also provide evidence for an association between autocrine TGF-β and PDGFR-mediated invadosome formation in RA synoviocytes that involves the production of PDGF-B induced by TGF-β.
ACKR4 on Stromal Cells Scavenges CCL19 To Enable CCR7-Dependent Trafficking of APCs from Inflamed Skin to Lymph Nodes

Published: March 2016

Dermal dendritic cells and epidermal Langerhans cells are APCs that migrate from skin to draining lymph nodes (LN) to drive peripheral tolerance and adaptive immunity. Their migration requires the chemokine receptor CCR7, which directs egress from the skin via dermal lymphatic vessels and extravasation into the LN parenchyma from lymph in the subcapsular sinus. CCR7 is activated by two chemokines: CCL19 and CCL21. CCL21 alone is sufficient for the migration of APCs from skin to LN. CCL19 and CCL21 also bind atypical chemokine receptor (ACKR) 4. ACKR4-mediated CCL21 scavenging by lymphatic endothelial cells lining the subcapsular sinus ceiling stabilizes interfollicular CCL21 gradients that direct lymph-borne CCR7+ APCs into the parenchyma of mouse LN. In this study, we show that ACKR4 also aids APC egress from mouse skin under steady-state and inflammatory conditions. ACKR4 plays a particularly prominent role during cutaneous inflammation when it facilitates Langerhans cell egress from skin and enables the accumulation of dermal dendritic cells in skin-draining LN. Stromal cells in mouse skin, predominantly keratinocytes and a subset of dermal lymphatic endothelial cells, express ACKR4 and are capable of ACKR4-dependent chemokine scavenging in situ. ACKR4-mediated scavenging of dermal-derived CCL19, rather than CCL21, is critical during inflammation, because the aberrant trafficking of skin-derived APCs in Ackr4-deficient mice is completely rescued by genetic deletion of Ccl19. Thus, ACKR4 on stromal cells aids the egress of APCs from mouse skin, and, during inflammation, facilitates CCR7-dependent cell trafficking by scavenging CCL19.
STAT3 Impairs STAT5 Activation in the Development of IL-9–Secreting T Cells
Authors: Olson Matthew R. , Verdan Felipe Fortino , Hufford Matthew M. , Dent Alexander L. , Kaplan Mark H.
Published: March 2016

Th cell subsets develop in response to multiple activating signals, including the cytokine environment. IL-9–secreting T cells develop in response to the combination of IL-4 and TGF-β, although they clearly require other cytokine signals, leading to the activation of transcription factors including STAT5. In Th17 cells, there is a molecular antagonism of STAT5 with STAT3 signaling, although whether this paradigm exists in other Th subsets is not clear. In this paper, we demonstrate that STAT3 attenuates the ability of STAT5 to promote the development of IL-9–secreting T cells. We demonstrate that production of IL-9 is increased in the absence of STAT3 and cytokines that result in a sustained activation of STAT3, including IL-6, have the greatest potency in repressing IL-9 production in a STAT3-dependent manner. Increased IL-9 production in the absence of STAT3 correlates with increased endogenous IL-2 production and STAT5 activation, and blocking IL-2 responses eliminates the difference in IL-9 production between wild-type and STAT3-deficient T cells. Moreover, transduction of developing Th9 cells with a constitutively active STAT5 eliminates the ability of IL-6 to reduce IL-9 production. Thus, STAT3 functions as a negative regulator of IL-9 production through attenuation of STAT5 activation and function.

Geology of the Passamaquoddy Bay Region, Charlotte County, New Brunswick
Authors: Cumming L M
Published: March 2016

Bedrock in the southwestern corner of New Brunswick provides the setting and topographical control for the International Passamaquoddy Tidal Power Project, an engineering proposal for converting the region's tidal forces into hydroelectric energy. Although the
Coldbrook Group (Precambrian) comprises the oldest rocks of the region, they arc of limited extent and Palaeozoic rocks predominate. New fossil (graptolite) evidence is presented for the Ordovician age of the Charlotte Group. The previously undivided Silurian rocks, extensively developed around the
margin of Passamaquoddy Bay, are correlated with formations in adjacent areas of Maine. Intrusive Devonian granitic rocks trend northeast across the entire region. Postorogenic sedimentary rocks of the Perry Formation (Upper Devonian) directly w1derlie Passamaquoddy Bay. Major folds within the area
appear to have been formed by a single compressive force, which produced regional strike-slip faults . Aeromagnetic maps of the region aid in tracing belts of volcanic rocks and in outlining structures and the distribution of intrusive rocks of various ages. A field excursion roadlog is provided
that points out some key geological relationships within the area.

Published: March 2016

The paper critically reviews the North American Late Tertiary and Quaternary mosses which, when described, were considered to have no equivalents in the recent moss flora. They are: CaZZiergon aftonianum Steere, C. hansenae Steere, Camptothecium woldenii Grout,
Drepanoa Zadus apieuZatus St eere, Drepa:noaZadus minnesotensis Williams and NeoaaZZiergon integrifoZium Williams. The most di stinct taxon is C. aftonianum , though its species status is questionable . Its diagnostic features were examined in detail, and critically discussed, on fossil specimens
extracted from Late Tertiary and interglacial deposits collected at localities shown in Figure 1 and Table 1. CaZZier gon ha:nsenae is not specifically distinct from C. aftonia:num. Camptotheaium woZdenii is apparently synonymous with Tomenthypnum nitens var . invoZutwn. DrepanocZadus apieuZatus is
within the present- day variability of D. revoZvens. D minnesotensis seems to be an extreme morphological form of D. exannuZatus. NeoaaZZiergon integrifoZium is also an extreme form of CaZZiergon trifarium..
Project egma seismic survey - Timmins, Ontario to Val d'Or, Quebec
Authors: Killeen P G , Hobson G D
Published: March 2016

A shallow seismic study of overburden was conducted in the Timmins - Val d'Or area as an aid to mineral exploration. The survey was funded under the Emergency Gold Mining Assistance Act program. Nearly 1400 hammer seismic refraction profiles, covering
approximately 350 line-miles in the A bitibi Clay Belt region, were completed during the winter of 1971-1972. Special problems involved with winter seismic operations were overcome. The results of the seismic depth determinations are presented in the form of 53 cross-sections showing sub-surface
apparent velocity structure. The bedrock topography was found to have relatively high relief and overburden thickness of 200 feet was not uncommon. Detailed seismic studies in the area of the Kam Katia Mine and Jameland Mine in Ontario indicate that the depth to bedrock is highly variable over short
horizontal distances.
Stratigraphy of the Shell Naskapi N-30 Well, Scotian Shelf, eastern Canada
Authors: Williams G L , Jansa L F , Clark D F , Ascoli P
Published: March 2016

The Shell Naskapi N-30 well, drilled to a depth of 7325 feet, penetrated approximately 6000 feet of Mesozoic sediments before encountering metamorphic basement at 6992 feet. Deposition was more or less continuous from the Middle Jurassic (resting on basement) to
the Early Maastrichtian, with possible periods of nondeposition in the Late Aptian and Late Campanian. Limestones and terrigenous sediments characterize the Middle and Late Jurassic. Maximum sand accumulation occurs in the Neocomian. Throughout the remainder of the Cretaceous the sandstone content
progressively declines with a consequent increase of muds tones and chalks. Late Jurassic and Early Cretaceous sedimentation was predominantly inner neritic, giving way to outer neritic, deeper shelf deposition in the Late Cretaceous. In the vicinity of Naskapi N-30, the Scotian Shelf appears to
have been relatively stable throughout the Mesozoic.
Geology and hydrothermal alteration at the Maggie porphyry copper-molybdenum deposit, south-central, British Columbia
Authors: Jambor J L
Published: March 2016

The Maggie porphyry copper depo sit is associated with early Tertiary porphyries that intrude for the most part the Permian Cache Creek Group. The copper -molybdenum zone, approximately 1300 by 300 metres in surface dime ns ions, averages about 0. 28% Cu .
The zone is centred in an elongate, westerly-dipping, multi -phase intrusive body that ranges in composition from granodioritic to granitic. Because abundant, cons picuous K- feld spar phenocrysts are present, the pluton is referred to as quartz monzonite porphyry. From the centre outwards the
succession of copper sulphides is (1) chalcopyrite with very minor bornite , ( 2) c halcopyrite, ( 3) chalcopyrite ± tennantite. Pyrite is present in all zones, but is most abundant in an irregularly - shaped, elongate halo that encloses the copper zone. Hydrothermal biotite is associated
closely with the copper sulphides, and because assay data were not available , the quality of biotitization has been used to establish the probable limits of 0. 2% Cu in several cross - sections. Microprobe analyses of numerous biotites indicate that their colour dee pens (and quality improves)
as Fe/Fe+Mg+Mnincreases. Biotitization is succeeded outwards by sericitization; along parts of the hanging wall of the deposit, intense sericitic alteration is accompanied by pervasive silicification. Propylitic alteration is present outs ide the zone of sericitization, but in Cache Creek rocks such
alteration is difficult to distinguish from the effects of low - grade regional metamorphism.
Experimental hydrogeochemical surveys of the High Lake and Hackett River areas, Northwest Territories
Authors: Cameron E M , Ballantyne S B
Published: March 2016

In 1974 surface lake waters were sampled using a helicopter from the High Lake and Hackett River areas, Northwest Territories. Both areas are in the zone of continuous permafrost and are underlain by granites, metavolcanic rocks and metasediments. The former area
contains a zinc-copper massive sulphide body, and Hackett River several zinc-lead-silver massive sulphides. One thousand square miles around High Lake were sampled at a density of one per 3. 5 .square miles. At Hackett River 12 square miles were sampled at a density of two per square mile. The pH
and the zinc and copper contents of the waters were analyzed in field laboratory equipped with atomic absorption spectrometer. A variety of elements (Si02, Al, Fe, Mn, Ca, Mg, Na, K, HC03, S04 and Cl) were later analyzed in Ottawa. The waters have a very low content of dissolved solids. The pH of
the waters correlates well with bedrock composition, being somewhat greater than neutral for volcanic rocks, including those containing calcareous beds, and slightly less than neutral for granitic rocks. The median content of zinc in the 285 waters from the High Lake area is 8. 8 ppb and for Cu less
than 1 ppb. Lakes near sulphide mineralization have much greater contents of these metals, which testify to their active, present-day oxidation in this permafrost terrain. The low iron and manganese contents of the water contribute to the mobility of zinc and copper. Limited data are given on
seasonal variation, which may be significant for weakly anomalous lakes. Hydrogeochemical methods of mineral exploration will likely be used more widely in this northern permafrost environment. As well as the active oxidation of sulphides and the migration of indicator metals, factors contributing
to their utility are the wide availability of water in lakes, streams and seeps, and the ease and rapidity of sampling, sample preparation and analysis.
Early Cretaceous Trigoniid Bivalves of Manning Provincial Park, southwestern British Columbia
Authors: Poulton T P
Published: March 2016

The lower Cretaceous (Hauterivian to Albian) Jackass Mountain Group of Manning Provincial Park, south­western British Columbia, contains 10 species of trigoniid bivalves. One species, Columbitrigonia jaakassensis, is new; 7 are not specifically identified.
Columbitrigonia. is described as a new genus, based on Trigonia aolumbiana Packard. Quoieaahia Crickmay is shown to be a valid genus although it has been questioned in the literature. Steinmanella Crickmay is considered to include Yaadia Crickmay, and to be a subgenus of Myophorella Bayle. Two
distinct trigoniid faunas are recognized. The older, Hauterivian and Barremian fauna contains Columbitrigonia jaakassensis n. sp., Quoieaahia aliaiae Crickmay, Myophorella (?Steinmanella) sp. A, as well as poorly preserved Apiotrigonia sp. cf. A. kayana (Anderson), A. sp. and Quoieaahia sp. The
younger, Albian fauna contains Myophorella (Steinmanella) sp. B., Columbitrigonia aoZumbiana (Packard), C.? sp. cf. C. aondoni (Packard), and probably also Pterotrigonia (Pterotrigonia) sp. The best preserved, and apparently the only remaining, specimen of the syntypes of Trigonia whiteavesi
(Packard) is redescribed in order to demonstrate the reality of the specimen, which has been considered previously as a partial restoration or complete reconstruction. The restricted ranges of the trigoniid bivalves of Manning Park indicate their considerable potential for biostratigraphic zonation
of the Lower Cretaceous rocks of western Canada and United States, but further study is required.
Ten stratigraphic sections from the Lower Cambrian Sekwi Formation, Mackenzie Mountains, northwestern Canada
Authors: Fritz W H
Published: March 2016

A Precambrian and early Lower Cambrian elastic succession underlies the Sekwi Formation and comprises the basal part of the formation at all but one section. The rest of the Sekwi at nine of the sections is predominantly carbonate that is assigned to a regional
unit called the middle carbonate belt. This belt is flanked on the northeast by an inner (near shore) detrital belt and on the southwest by an outer (basinal) detrital belt. One Sekwi section is almost wholly within the outer detrital belt. This section, together with sections containing some outer
detrital strata, locally defines a northeasterly directed protrusion of the outer detrital belt into the middle carbonate belt. Sekwi strata within the middle carbonate belt are grouped into two major elastic-carbonate pairs, or grand cycles. The mentioned Precambrian-early Lower Cambrian elastic
succession and an overlying thick carbonate succession constitute the lower cycle. The elastic part of the second grand cycle consists of inner detrital strata believed to have been deposited over a carbonate bank (top of first cycle) during a regional regression. The carbonate part of the upper
grand cycle is by far the thickest of the four half-cycles within the formation. Three and locally four subcycles are tentatively recognized in this half-cycle. Sekwi deposition closed near the end of Lower Cambrian time when a gradual transgression deposited dark, platy limestone and shale over
uppermost Sekwi carbonates belonging to the medial and upper part of the Bonnia-Olenellus Zone.
Distribution of hydrothermal clay minerals in the Valley Copper Porphyry deposit, Highland Valley, British Columbia
Authors: Jambor J L , Delabio R N
Published: March 2016

Kaolinite, chlorite, illite, and montmorillonite were determined for the clay ( < 2 ? m) fraction of more than 250 samples from the hydrothermal alteration aureole of the Valley Copper porphyry deposit. Chlorite content in the clay fractions of the
samples is low, but the other three minerals are abundant within and beyond the copper zone. In most rocks with extremely intense mega scopic argillic alteration, the total of kaolinite plus montmorillonite exceeds 75 per cent of the clay-mineral fraction, and montmorillonite generally predominates.
Rocks with this type of intense, "chalky" alteration, are concentrated in the upper, central part of the copper zone, and decrease laterally and with depth. Areas in which kaolinite exceeds illite are irregular, but somewhat elongate in plan, are steep to only slightly inclined in cross-section, and
are not restricted to the copper zone. Kaolinite-illite ratios do not seem to vary systematically with depth in the deposit. Neither the intensity of argillic alteration nor the distribution of specific clay minerals seems to be related to sulphide zoning . Pervasive argillization is interpreted to
have been a late-stage, post-sulphide alteration.
Causes of cretaceous oscillations of sea level in western and Arctic Canada and some general geotectonic implications
Authors: Jeletzky J A
Published: March 2016

Refined biochronological studies revealed an almost complete lack of interbasinal correlation of Cretaceous transgressions and regressions in Western and Arctic Canada. A comparison with the literature data available indicates that the same is true of the
Cretaceous transgressions and regressions the world over and indeed of all Phanerozoic transgressions and regressions on the global scale. These data contradict the presently fashionable hypothesis claiming that the Phanerozoic transgressions and regressions were caused largely or entirely by
geologically instantaneous, worldwide eustatic oscillations of sea level. The popularity of this hypothesis appears to be caused by: 1. Currently widespread neglect of the biochronological method of age determination coupled with an unjustified reliance on incomparably less precise and commonly
unreliable physical methods of age determination (e.g. radiometry or magnetostratigraphy); and 2. The common lack of realization that many (?most) Phanerozoic tectonic movements (orogenic as well as epeirogenic) were very rapid events which lasted only from one to a few zonal moments in terms of the
biochronological standard. These pulses occurred very frequently and had local to regional (apparently never global) extent. As eustatic oscillations of sea level undoubtedly occurred in the past, the almost total absence of their record in Phanerozoic rocks must be due to the subsequent destruction
(overprinting) by the tectonic movements. This is indicated by: 1. The short duration and frequent occurrence of orogenic and epeirogenic pulses; and 2. The minor amplitude of eustatic oscillations as compared with that of tectonic pulses. The amplitudes of eustatic oscillations apparently averaged
only 40 to 110 m and did not exceed 300 m (i.e. from -150 to + 150 m). The estimated vertical amplitudes of minor tectonic movements ranged from 200 to 2000 m. The amplitudes of eustatic oscillations are, therefore, almost an order of magnitude less than those of the minor (let alone medium to large
which have amplitudes of several to many thousands of metres) tectonic movements. Because of the overprinting, the effects of ancient eustatic oscillations may only be preserved either during infrequent tectonically quiescent intervals in the Phanerozoic history of the globe (e.g. the global
Maastrichtian regression) or within such most stable tectonic elements of the continental crust as Precambrian shields and stable shelves.
The geology, mineralogy, and geochemistry of the captain sulphide deposit, Gloucester and Northumberland counties, New Brunswick
Authors: Tupper W M , Bachinski D J , Boyle R W
Published: March 2016

Mapping at a scale of 1 inch to 400 feet was carried out near the Captain deposit. Drill core and polished and thin sections of the sulphides and host rocks were examined megascopically and microscopically, and the host rocks were chemically analyzed for their
major and trace c onstituents . Middle Ordovician sedimentary and volcanic rocks of the Tetagouche Group are hosts for the deposit. The stratigraphic sequence, in ascending order, is: andesite, rhyolite porphyry, quartz augen-schist, argillite, greywacke, quartz augen-schist, and rhyolite. These
rocks strike north and dip to the west. The enigmatic quartz augen-schist probably resulted from the introduction of siliceous pyroclastic material into a sedimentaryvolcanic basin characterized by a shale -greywacke type of sedimentation . The deposit consists of disseminated and locally massive
pyrite and chalcopyrite with minor amounts of sphalerite, galena, pyrrhotite, arsenopyrite, linnaeite, covellite, cassiterite, stannite, magnetite, krennerite, petzite, stibnite, and galenobismutite. Replacement and exsolution textures are common. The sulphides replace quartz augen-schist and
argillite, especially along their contact. The sulphide zone is associated with a tight drag -fold which has an arcuate axial trace . The host rocks contain minor amounts of Cu, Pb, Zn, Ni, Co, Au, and Sb. Anomalous amounts of these metals occur only in the massive and disseminated sulphide zones.
The metal distribution patterns do not suggest that the metals were mobilized from the adjacent host rocks and deposited in the sulphide zone. The presence of replacement and exsolution textures in the ore, the discordant nature of the sulphide zone, the obvious structural control of the deposit,
and the metal distribution patterns in the host rocks suggest the Captain deposit is epigenetic in origin.
Computation of synthetic seismograms for marine refraction studies
Authors: Keen C E
Published: March 2016

A method for calculating synthetic seismograms is presented which can be used for comparing real seismic refraction data obtained with ocean bottom seismometers with that computed for an assumed earth model. The model consists of flat-lying , homogeneous, elastic
layers overlain by a fluid half-space. The thickness, P and S wave velocities, density, and specific attenuation factors are specified for each layer. The source is an explosion within the fluid whose detonation depth and size are known. The method involves the calculation of the generalized plane
wave reflection coefficients for the structure at different angles of incidence and frequencies. These coefficients then form part of integral expressions for the reflected spherical wave field which are evaluated by numerical quadrature. The use of a computer program for the generation of synthetic
seismograms, which correspond to the vertical component of particle velocity at the sea floor and are modified by the frequency response of the recording instruments, is described. Examples of computed seismograms and the specification of numerical parameters used as part of the program input are
given.
Report on the surficial sediment distribution of the Great Lakes part 1: Lake Ontario
Authors: Thomas R L , Kemp A L W , Lewis C F M
Published: March 2016

Three major sediment units are recognized in the surficial sediments of Lake Ontario on the basis of extensive sampling and echo sounding: (1) glacial till and bedrock; (2) glaciolacustrine clay; (3) postglacial mud. Sand and silt are minor units in the Ontario
surficial sediments. The sediment distribution pattern is essentially simple with a natural superposition of sediment units reflecting the glacial and postglacial history of the lake. The inshore region of Lake Ontario is composed of glacial till and bedrock. The till is overstepped in deeper water
by glaciolacustrine clays which are themselves overstepped by postglacial muds. Two north-south sills, composed of glaciolacustrine clay, subdivide the main basin of Lake Ontario into three distinct basins of postglacial mud accumulation. The surficial sediments contain variable amounts of quartz,
feldspar, clay minerals, organic carbon and calcite. Quartz and feldspar contents are greatest in the coarser inshore sediments while clay minerals and organic carbon contents are greatest in the finer offshore sediments. Carbonate content is generally low throughout the lake. Illite is the dominant
clay mineral with lesser amounts of chlorite and kaolinite. Mean rates of sedimentation ranging from 114 to 309 g/m2/y = ea = r are estimated for the basins of modern mud accumulation. The primary source of detrital material is believed to be the extensive glacial deposits of southern Ontario and
northern New York State. An estimated 55% of this material is derived from the drainage basin while the remaining 45% is the result of shoreline and lake bottom erosional processes. The textural characteristics, defined by moment measures, of the modern sediments can be interpreted as
resulting from the varying degrees of mixing between a sand-and a clay-size end member population; the former occurring in the nearshore zone and the latter in the offshore basin deposits. Both end member populations are leptokurtic and skewed due to the introduction of silt-size material in the
form of CaCO3 probably as the product of lake-wide precipitation. Mean grain size and standard deviation, predictably show trends from nearshore to offshore, with decreasing grain size, related to increasing water depth and hence to decreasing energy from a wave­and current-active nearshore region
to an offshore region of quiet water with sedimentation from suspension. ln addition, skewness and kurtosis show trends relative to mean grain size and standard deviation which can be explained in terms of increasing distance from shore. Variations in the compositional phases of the sediment in
terms of quartz, clay and organic carbon, and also variations in the redox potential can in turn be related directly to textural characteristics of the sediment and consequently to the depositional environment.
