Une hégémonie compétitive contre vents et marées : les élections générales de 2015 en Tanzanie et à Zanzibar
Authors: Fouéré Marie-Aude , Maingraud-Martinaud Cyrielle
Published: March 2016

En Tanzanie, pour la cinquième fois depuis le retour au multipartisme, les élections générales d’octobre 2015 ont abouti à une nette victoire de l’ancien parti unique, le CCM (Parti de la Révolution). Le parti au pouvoir a su surmonter ses divisions internes, rendre son candidat à la présidentielle populaire en activant les ressorts de la moralité politique, en jouant les atouts du patronage, de la cooptation et du quadrillage de la population et, enfin, en utilisant à son profit le système institutionnel et électoral pour assurer sa reconduction. À Zanzibar, cependant, c’est un pouvoir vacillant qui se dévoile dans le recours à des pratiques autoritaires pour empêcher la victoire de l’opposition : depuis l’annulation de ses élections, l’archipel est plongé dans une crise dont l’issue est encore incertaine.
Abusing text in the Roman and contemporary worlds
Authors: Middleton Francesca
Published: March 2016

In this comparison of portraits of authorial anxiety, I focus on contemporary attitudes to fan fiction and on discussions of authors in Imperial Rome (notably Galen and Martial) to consider the assumptions of textuality that frame imagined textual abuse. Revealed are parallel discourses for different concerns—for the reader as a potentially ill-educated consumer and the text as an object in the ancient world; in the contemporary world, for the author's personal violation and the text as an agent within readerly experience. I discuss how fan fiction's lack of commercial publication is used to distinguish it from other contemporary literature within this framework. Fan fiction's noncommercial publication can thus be appreciated as a marginalizing act in itself.
Fan fiction, early Greece, and the historicity of canon
Authors: Kahane Ahuvia
Published: March 2016

The historicity of canon is considered with an emphasis on contemporary fan fiction and early Greek oral epic traditions. The essay explores the idea of canon by highlighting historical variance, exposing wider conceptual isomorphisms, and formulating a revised notion of canonicity. Based on an analysis of canon in early Greece, the discussion moves away from the idea of canon as a set of valued works and toward canon as a practice of containment in response to inherent states of surplus. This view of canon is applied to the practice of fan fiction, reestablishing the idea of canonicity in fluid production environments within a revised, historically specific understanding in early oral traditions on the one hand and in digital cultures and fan fiction on the other. Several examples of early epigraphic Greek texts embedded in oral environments are analyzed and assessed in terms of their implications for an understanding of fan fiction and its modern contexts.

Dynamic Response of a Rotating Beam Influenced a Moving Load and Gyroscopic Effect with Timoshenko Beam Model
Authors: Shahravi Morteza , Temsal Mohammad , Ghafari Hamed , Azimi Milad
Published: March 2016

This article is presents a finite element formulation for the dynamic response of a rotating simply supported shaft subjected to a moving load. The Timoshenko beam theory is used to model the rotating shaft. The assumed modes method and Finite Element method are employed in this study. The equations are solved with numerical method. The influence of parameters moving load speed and rotational speed are discussed for rotating simply supported shaft model. The results show that the maximum displacement occurs in the direction of the load at the midpoint of the simply supported shaft. The gyroscopic effect occurs only in the direction perpendicular to the load and is dependent on rotational speed of the shaft.
Integral Sliding Mode Control Approach for 3-Pole Active Magnetic Bearing System
Authors: Huynh Van Van , Tran Minh Hoang Quang
Published: March 2016

In this paper, a new integral sliding mode control scheme is designed for the 3-pole active magnetic bearing system. First, a new integral sliding surface is designed such that the 3-pole active magnetic bearing system in the sliding mode is asymptotically stable under certain conditions. Then, an adaptive controller is designed to solve the unknown upper bound of matched uncertainty and guarantee the reachability of the integral sliding surface. Finally, the performance of the proposed integral sliding mode controller is applied to 3-pole active magnetic bearing system to demonstrate the efficacy of the proposed method.

Authors: Shedbale Amit S. , Sharma A.K. , Singh Indra Vir , Mishra B.K.
Published: March 2016

In this work, 2-D/3-D forming problems (extrusion and deep drawing) are numerically simulated by extended finite element method (XFEM). The updated Lagrangian formulation is used to model the large deformation. The von-Mises yield criterion is used to model the elasto-plastic behavior assuming isotropic hardening. Penalty approach is employed to impose the contact constraints and non–penetration condition at the material interfaces. The level set approach is used for locating the material interfaces. The numerical simulations of two forming problems are presented using developed nonlinear XFEM code.

Published: March 2016

Vapour compression heat pump will have good prospects in future large-scale spacecraft thermal control technology. Its environmental reliability and safety needs to be tested on the ground before being carried with the spacecraft launch. Vibration test is used to assess the anti-vibration capability in its transport and use. It is essential to build a performance test system of vapour compression heat pump to explore its operating characteristics at a given random vibration conditions. The results shows that the vapour compression heat pump is normal operation after the vibration and the cooling performance (COP) of 3.09 is achieved. Vibration test is equipped to provide a guarantee for future success carrying. The performance of vapour compression heat pump at high and low temperature and vacuum environment will be carried out.

Published: March 2016

In this study, A357 (Al-7%Si-0.5%Mg) alloy/Al2O3 composites with various volume fractions (4%, 8%, 10%) were prepared by using permanent mould casting. In addition, A357 alloys were cast for comparison purposes. The alloys and composites were given a T6 heat treatment process (solution treatment and artificial ageing), Also microstructure, hardness and tensile properties of these composites were evaluated and compared. In addition, tribological properties of these composites were evaluated using a Pin-on-Disc apparatus at a constant sliding velocity of 1m/s and pressure of 0.35 MPa. The microstructure of the composites shows homogenous distribution of Al2O3 plate-like particles in the Al matrix except in the A357/10%Al2O3 composite. The wear and mechanical properties of composites improve with increasing the volume fraction of Al2O3 upto 8% and then decreases. Particularly, mechanical properties of the A357/10%Al2O3 composite are lower than the alloy indicating that the critical volume fraction of Al2O3 reinforcement in the A357 alloy is 8%. Wear morphology studies show that abrasive and delamination wear are extensive in the alloy whereas the slight delamination wear with some abrasive grooves are found in the composites.
The Effect on the Dry Sliding Wear Behavior of Gravity Cast A357 Reinforced with Dual Size Silicon Carbide Particles
Authors: Avinash L. , Ramprabhu T. , Bontha Srikanth
Published: March 2016

In the present study, the composites of A357 (Al-7%Si) alloy reinforced with the bimodal sizes (~250µm (L) and ~38 µm (S)) of 6wt% SiCp and the A357 alloy were prepared by permanent mould die casting. Three different combinations of bimodal distributions were considered: (3% L + 3% S, 4% L + 2% S, and 2% L + 4% S). The wear behavior of the alloy and the composites was studied for the speed of 1 m/s and load conditions of 10-30 N with an interval of 5 N in a pin on disc apparatus. The hardness and microstructure of the composites were also characteristised. The results suggest that the addition of bimodal size of particles significantly improves the hardness and wear resistance of the alloy. Among the different combinations, the 4% L + 2% S bimodal distribution combination provides the highest wear resistance and the hardness. This result indicates that the higher amount of large size particles are more important than that of small size particles to improve the wear resistance, which implies that the particle decohesion is the rate controlling step in the present investigation. The wear rate increases with an increase of load and sliding distance. The critical load to enter into the severe wear regime for the alloy and composites is 25 N. The rapid wear loss begins above 1500 m sliding distance in the composites and the as cast alloy. The wear rate curve with respect to the sliding distance shows three regimes (1) transition period (2) steady state (3) severe wear state. The wear morphology studies show that the abrasive wear is the main wear mechanism in the bimodal size composites whereas the delamination wear is predominant in the alloy.
Pitfalls of CO2 Injection in Enhanced Oil Recovery
Authors: Marques Luiz Carlos do Carmo , Pimentel Daniel Monteiro
Published: March 2016

The intent of this paper is to offer a comprehensive understanding of the pitfalls associated with CO2-rich gas injection during enhanced oil recovery (EOR) operations. An emphasis is placed, however, on the interactions between this gas and crude oil asphaltenes, because these later compounds are heavy organic molecules which can destabilize, flocculate and precipitate in CO2-rich environments, thus triggering a major field problem: injectivity loss due to near-wellbore (inflow) formation damage: an Achilles heel for any EOR process.

Published: March 2016

Monoethylene glycol (MEG) is being widely applied as thermodynamic inhibitor to avoid formation of natural gas hydrates. High hydrophilicity, low toxicity, low viscosity, low solubility in liquid hydrocarbons and high capacity of dissolving salts are advantageous for the use of MEG in the natural gas production. In addition, MEG recovery can be easily achieved considering its low volatility in relation to water, which makes the process economical and environmentally feasible. The reuse of MEG is being theme of research and phase equilibrium data for the involved species are required. In this work, a experimental procedure to synthetize iron carbonate and, afterwards, determine its solubility in aqueous mixtures of MEG in the presence of carbon dioxide atmosphere have been developed. Furthermore, a series of solubility data has been measured. This work presents a worthy contribution to the description of iron carbonate aqueous solubilities in the presence of MEG and carbon dioxide, regarding the instability of the salt to respect of oxidation. Subsequently, the knowledge of the behavior of the iron carbonate solubilities is useful for the industrial unities of production of natural gas and recovery of MEG.
Nickel Oxides Supported on Alumina as Oxygen Carriers for Chemical-Looping Combustion and Reforming of Methane
Authors: Barbosa Renato Dias , da Cruz Gilberto Marques , Abreu dos Santos Pedro Henrique Lopes Nunes , Cortez Gilberto Garcia , Rodrigues José Augusto Jorge
Published: March 2016

Chemical-Looping Combustion (CLC) and Chemical-Looping Reforming (CLR) processes are technologies in development, considered as economically viable alternatives for CO2 mitigation. Both processes employ two interconnected reactors (air reactor and fuel reactor), by which oxides particles (called oxygen carriers) circulate. CLC process produces heat with inherent separation of CO2 from gaseous hydrocarbons combustion. CLR process performs the fuel partial oxidation, generating synthesis gas (H2 and CO), which is the major industrial intermediate for hydrogen (H2) and other hydrocarbons production, thru Fischer-Tropsch reactions. The employment of OCs enables the total or partial oxidation of fuel, in the absence of atmospheric air, which allows great reduction of the separation costs. Nickel-based OCs are the most investigated, showing high performance and reactivity. This work presents the synthesis of OCs composed by different contents of nickel oxides supported on alumina, textural, physical and chemical characterizations by several techniques, and experimental results obtained when these materials were applied to CLC and CLR processes, using CH4 as fuel, mixed or not, with H2O or CO2. The results showed the potential industrial applications of these materials, which are preferentially selective to the CLR process, and the addiction of H2O or CO2 greatly reduces the carbon deposition.

Authors: de Oliveira Leonardo Hadlich , Meneguin Joziane Gimenes , da Silva Edson Antonio , de Barros Maria Angélica Simões Dornellas , Arroyo Pedro Augusto , Grava Wilson Mantovani , do Nascimento Jailton Ferreira
Published: March 2016

In this work, experimental data of CO2 capture by adsorption was determined gravimetrically, at 30 °C and pressures up to 40 bar, and in a fixed bed unit at 20 bar, using NaY as adsorbent. Langmuir, Sips and Tóth isotherm models were used to correlate the equilibrium data. Sips and Tóth models were best fitted allowing estimate the maximum CO2 adsorbed amount. The breakthrough curve was modeled using Linear Driving Force (LDF) and Thomas models. The LDF model represented better the CO2 breakthrough curve than Thomas model. The mass transfer resistance in NaY micropores can be assumed as the limiting step for CO2 adsorption in fixed bed, since the intraparticle mass transfer coefficient of LDF model was smaller than the experimental overall volumetric mass transfer coefficient, although external film resistance is not negligible.
CO2 Pipelines: A Thermodynamic Modeling with Pre-Salt Applications
Authors: de Medeiros José Luiz , de Araújo Ofélia Queiroz Fernandes
Published: March 2016

This paper approaches CO2 pipelines operating with high dense compressible flow for Enhanced Oil Recovery (EOR) and/or Carbon Capture & Geological Storage (CCGS). The idiosyncrasies of high pressure CO2 flow are discussed and an appropriate and rigorous steady-state compressible flow pipeline model is disclosed. The model gives three Ordinary Differential Equations (ODE) which result from one-dimensional, one-phase, Mass, Momentum & Energy Balances along the pipeline axial direction. This ODE set is numerically integrated leading to profiles of temperature, pressure and inventory along the pipeline, which are basic for design. An example is explored in the context of a hypothetical EOR CO2 pipeline aligned to the production of CO2 rich natural gas in the Pre-Salt offshore oil and gas fields on the southeast coast of Brazil.
Potential for semiochemical-based monitoring of the pea leaf weevil (Coleoptera: Curculionidae) on field pea (Fabaceae) in the Canadian Prairie Provinces
Authors: Evenden M.L. , Whitehouse C.M. , St. Onge A. , Vanderark L. , Lafontaine J.-P. , Meers S. , Cárcamo H.A.
Published: March 2016

The pea leaf weevil, Sitona lineatus (Linnaeus) (Coleoptera: Curculionidae), is an important pest of field peas, Pisum sativum Linnaeus (Fabaceae), and faba beans, Vicia faba Linnaeus (Fabaceae), that has recently become established in the Prairie Provinces of Canada. Male pea leaf weevils produce an aggregation pheromone, 4-methyl-3,5-heptanedione, in the spring when overwintered weevils migrate to fields to feed and mate. The current study tests the attractiveness of the aggregation pheromone with and without synthetic bean volatiles to pea leaf weevils in the spring and in the fall when weevils seek perennial legumes to feed and overwinter. Modified Leggett traps similar to those used in Europe did not retain weevils in this study. Aggregation pheromone-baited pitfall traps caught male and female weevils in the spring and fall. Weevils were not attracted to traps baited with three bean volatiles, (Z)-3-hexen-1-yl acetate, (Z)-3-hexen-1-ol, and linalool. Bean volatiles did enhance response to pheromone, but only in the fall. Weevils were captured in most semiochemical-baited traps in a 1:1 sex ratio, but female-biased catch in control traps might indicate greater activity of females in the trap vicinity. This study lays the groundwork for semiochemical-based monitoring to detect pea leaf weevil spread in the Prairie Provinces.

Published: March 2016

Giant genital warts (GGW) represent a rare form of sexually transmitted disease caused by the human papillomavirus, arising more frequently in the vulvar and perianal regions as large exophytic cauliflower-like mass. Estimated rate of recurrence is 60 to 66%, while malignant transformation is possible and it has been reported in 30 to 56% of cases. A 45- years-old woman was admitted to our Structure of Plastic and Reconstructive Surgery, Siena, Italy with an extensive cauliflower- like masses diffused on vulvar and perianal region. The patient was treated in general anaesthesia, with a wide en bloc excision up to free clinical edges and immediate reconstruction of the vulvar continuity. Buschke Lowenstein tumour or giant genital warts is a sporadic tumour with an elevate local recurrence rate. In some cases, surgery can be very difficult and it must be associated to other strategies. An accurate follow-up is always necessary
THE HUMAN RACHIS: CAN IT BE CONSIDERED A SHOCK ABSORBER (THAT WAS PRODUCED BY EXAPTATION) RATHER THAN A COLUMN?
Authors: Tanga M. , Ghelli F. , Gelati G.
Published: March 2016

Our paper is focused on two fundamental points: the first one is a terminological proposal and the second one is a question. Obviously these two things are strictly related one another. The terminological proposal is aimed to name “vertebral shock absorber” the human rachis (globally considered, when it is in physiological conditions) in its most typical function: to sustain static/dynamic stresses, that moreover are directed according to its axial direction, obviously when this coincides with gravitational line. This aspects can be studied by modal analysis and by the model of Eigenvectors and Eigenvalues. According to our opinion, the mechanical feature must be considered as prevalent if compared with the structural one. Following it human rachis is usually named “column”. This mechanic sustain is distributed on three lines that are summarily parallel and are linked one another (by isthmuses and vertebral arches to build an horizontal ring) so they can be considered a unique compact viscous-elastic system. Each one of these three vertical sub-structure is built as a stacking of metameric elements (modules) along a continuous line.
Geological and engineering aspects of Upper Cretaceous Shales in western Canada
Authors: Scott J S , Brooker E W
Published: March 2016

Overconsolidated shale is herein defined as a sedimentary deposit composed primarily of silt-and clay-sized particles dominated by members of the montmorillonite group of clay minerals and the deposit has been subjected to consolidation loads in excess of those
provided by the present overburden. From an engineering standpoint these materials constitute one of the major problem soil types. Predictions of the engineering performance of overconsolidated clay shale either on a short or long term basis cannot as yet be made with reasonable confidence in spite
of proven statical theory and modern laboratory testing techniques. Overconsolidated clay shales of Upper Cretaceous age occur extensively in Western Canada where they cause stability problems for foundations and slopes. In order to assess the geological factors affecting the engineering behaviour
of overconsolidated clay shales the Bearpaw Formation was selected as the primary unit for study. Slope failures involving the Bearpaw Formation or its stratigraphic equivalents were examined at various areas in Manitoba, Saskatchewan, and Alberta, from which it is concluded that the prime
geological factors affecting the engineering behaviour of overconsolidated shales are: 1) depositional environment; 2) lithology and stratigraphy; 3) stress history; 4) structure; 5) climate; 6) geomorphology; and 7) groundwater. The geometry of the failure surface of the retrogressive slides that
are common in the overconsolidated clay shales of Western Canada is best described by a number of plane surfaces rather than by a circular arc. Therefore the wedge method of stability analysis appears to offer a promising approach to slope stability prediction for these materials. Peak (Ql ' ) and
residual(~ R) strengths of over consolidated shales obtained from drained direct shear tests are usefully applied in an upper and lower limit approach to the problem of stability analysis. The important unknown in stability analyses for prediction purposes is the value of the Residual Strength
Index.

Regional, lithological and temporal variation in the abundances of some trace elements in the Canadian Shield
Authors: Eade K E , Fahrig W F
Published: March 2016

Samples of rocks during reconnaissance geological mapping by Geological Survey of Canada field parties have been used to estimate the average abundance of some trace elements in the surface crystalline rocks of the Canadian Shield. The preferred values are as
follows, in ppm: Ni, 19; Cu, 26; Zn, 60 ; Pb, 18; V, 59; Sc, 12 ; Y, 21; La, 71; Zr, 190 . Regional variations in trace element content of the rocks suggest that Pb is mobile under high grade regional metamorphism but that Ni , Co, Cu, Zn, V, and Scare relatively immobile and tend to be concentrated
in rocks of granulite facies. Ni is more abundant and Pb and Zn less abundant in Archean rocks than in Proterozoic rocks. Rocks of some of the sample areas show higher than average contents of some trace elements, for example, rocks of Fort Enterprise area are high in Ni and Cu and rocks of Battle
Harbour - Cartwright are high in Zn.
Ordovician strata of the Hudson Bay Lowlands
Authors: Cumming L M
Published: March 2016

Ordovician strata outcrop in two belts, each with different facies, along the southwestern and southeastern sides of the Hudson Platform. Limestone and minor sandstone form a continuous belt, 840 miles long, extending from North Knife River, Manitoba to the
Kenogami River, Ontario. The belt is from 10 to 40 miles wide and is truncated in the south by a major fault scarp. This remarkably uniform belt of Ordovician rocks represents the southwestern and western margins of the Hudson Bay and Moose River Basins respectively and includes the Bad Cache Rapids
Group, the Churchill River Group and the Red Head Rapids Formation. The thickness of the strata varies, from southwest to northeast, from a few feet at the wedge-edge to over 600 feet in the subsurface. The average thickness of the composite Ordovician section in the northern part of the outcrop
belt is about 300 feet. Arkosic sandstone, calcareous sandstone, and shale comprise a smaller Ordovician outcrop belt, 30 miles long, near the southeastern extremity of the Hudson Bay Lowlands in Quebec. Toward central Moose River Basin these strata grade into dolomite, 300 feet thick. In the Moose
River Basin and along the southwestern edge of the Hudson Bay Basin, Archean crystalline rocks form the basement and the non-conformably overlying Ordovician strata are the oldest Paleozoic rocks.
Ontaratue river (106J), Travaillant lake (106-O), and Canot Lake (106P) map-areas, District of Mackenzie, Northwest Territories
Authors: Cook D G , Aitken J D
Published: March 2016

The exposed stratigraphic succession in the three NTS map-areas (106J, 106-0, and 106P) consists of Middle Devonian, Upper Devonian, and Lower Cretaceous strata. Older rocks down t o and including Proterozoic strata have been encountered in exploratory wells. The
total succession is interrupted by at least five unconformities, the most pronounced of which is the sub-Cretaceous unconformity. Relief on the sub-Cretaceous surface appears to be primarily paleotopographic with some structural modification. Local folding and faulting affected Devonian strata and
apparently pre -dated Cretaceous strata. Broader, more regional structures appear to be in part older and in part younger than Cretaceous rocks. Among the engineering problems expected within the map - areas are those which would result from the tendency of several formations to undergo gravity
slumping, and also the sparse distribution of rocks suitable for riprap. Although it is possible that base metals exist in the report-area, the greatest economic potential is for oil and gas.
Seismic structure of the continental margins and ocean basins of southeastern Canada
Authors: Jackson R , Keen C E , Keen M J
Published: March 2016

The results obtained from seven crustal refraction lines and 23 expendable sonobuoys are described. Six of the crustal refraction lines are parallel to the continental margin off Nova Scotia or the southern Grand Banks. The refraction data from the former area
may limit the continent-ocean transition to a zone of 75 km or less while the data from the later area suggests a transition zone of 36 km or less. One crustal refraction line with typical oceanic structure was obtained in the Newfoundland Basin. The results from the expendable sonobuoy wide angle
reflections and refractions are grouped according to area. The 14 sonobuoys launched over the Sohm Abyssal Plain measured three ranges of velocities, 1. 7 to 2. 2 km/sec , 2. 2 to 2. 7 km/ sec, and 2. 7 to 3. 7 km/sec. Six expendable sonobuoys launched in the vicinity of the Newfoundland fracture
zone measured two distinct groups of velocities, 1. 94 to 2. 14 km/sec and 3. 70 to 3. 95 km / sec. Three other expendable sonobuoys were launched and are discussed separately.
Development of a computer-based file on oil and gas pools
Authors: Dickie G J , Williams G D
Published: March 2016

Oil and gas pools are definable mineral deposits on which geological measurements can be made. The geological data are syntheses of observations made in one or more wells in which the oil or gas is encountered, and may be either descriptive or quantitative. The
data recorded for each pool were grouped into six categories based on file design and data accessibility. These categories are: Identification and location, stratigraphic sequence, unconformity data, lithological data, geometry, and reservoir and production data. Difficulties arose in defining the
location and shape of the pool and also in recording the lithology and stratigraphy of the reservoir and related rocks. The shape of the pool is defined by the dimensions and orientation of two orthogonal axes drawn within the pool. The location is taken at the well drilled nearest the intersection
of the two axes. Lithology and stratigraphic sequence are based on the reservoir unit. The formal stratigraphic designation (group, formation , member) of units overlying and underlying the reservoir constitutes the stratigraphic sequence. A record of the lithology of the reservoir unit and of the
rocks 1 00 feet (30.5 m) above and below the reservoir is satisfactory for regional analysis. The major part of a file on 1 1 00 Cretaceous and Jurassic oil and gas pools in Alberta using this file design was completed in two years at a data collection cost of $5 500. File operation costs using the
SAFRAS system have been minimal.
Some observations on the solubility of gold
Authors: Boyle R W , Alexander W M , Aslin G E M
Published: March 2016

Solubility experiments confirm that gold can be transported in natural humic waters probably in the form of a metal organic compound, as a chelate, or adsorbed to huinic matter. In gossans and in auriferous sulphide (pyritic) deposits similar experiments indicate
that gold can be transported in ferric sulphate so lutions. Under hydrothermal conditions gold is readily soluble in alkali carbonate so lutions containing Il2S, AsH3, or SbH 3 or combinations of these constituents.
Detailed hydrogeochemistry of two small lakes in the Grenville geological province
Authors: Jonasson I R
Published: March 2016

An extensive study of some hydrogeochemistry of waters and sediments of two lakes, Perch and Lavant Long, located in forested regions of the Grenville Geological Province, Lanark County, Ontario, has been made. Although discussion is based almost entirely on
simple analytical data for a number of metals, zinc, lead, copper, iron, manganese, mercury, arsenic, nickel, molybdenum and uranium and on data for organic carbon, carbonate and sulphur in organic and inorganic ( silty) sediments, it is possible ta postulate some hydrodynamic mechanisms to explain
relative degrees of dispersion and precipitation of these metals in the sediments of the lake. Taken in conjunction with analytical data for waters, for zinc, lead, copper, mercury, nickel and uranium the different dispersion patterns present suggest that: iron and manganese hydrolyzate ions form
weak associations with organic matter with which they coprecipitate and accumulate and then are fixed by sulphide ions in deep water organic sediments; zinc, lead, arsenic and possibly mercury ions precipitate mainly as stable insoluble organic complexes and subsequently are fixed by sulphide ions
in sediments in zones of the lake where water movement is greatest. Copper, nickel, uranium and mercury which likely form the most stable soluble organic chelates, are most widely dispersed and eventually settle into sediments by coprecipitation-absorption mechanisms on organic particles. They tao
are subsequently fixed by sulphide ion except perhaps uranium which is immobilized upon reduction. The implications of the se findings on regional geochemical reconnaissance survey programs also are discussed along with the relative virtues of sampling deepwater organic sediments versus those from
shoreline areas which are mainly inorganic ( or silty) types.
Terrain characterization and evaluation : an example from eastern Melville Island
Authors: Barnett D M , Edlund S A , Dredge L A
Published: March 2016

This paper explains the methodology of an integrated (interdisciplinary) 1: 125 OOO scale mapping project on eastern Melville Island and describes the style of data presentation used in Geological Survey of Canada Open File 252 (Barnett et al., 1975a) which
includes photomosaic maps accompanied by expanded legends. The legend is organized to show geological, geomorphological, botanical, and some wildlife data. These data appear in the upper part of the expanded legend. In the lower part they are interpreted and converted into simple numerical
evaluations suitable for aspects of land - use management. The data are arranged into a hierarchy with three levels of detail identified as Landscape Type (regional), Geobotanical Facies (intermediate), and Terrain Units (local). Each sedimentary bedrock formation has a distinctive morphological
development with associated suites of landforms and vegetation. The combinations of attributes which make each Landscape Type distinctive are set out in a matrix. The particular significance of veneers, the marine limit, vegetation, and ground ice is explained. The basis for evaluation of
trafficability and sensitivity, and the potential utility of integrated mapping for wildlife studies is outlined. Guidelines for nonspecialist users are set in nontechnical language.
Geology of the Amoco Imp Skelly A-1 Osprey H-84 well, Grand Banks, Newfoundland

Published: March 2016

Upper Triassic evaporates are now known from the northwest Atlantic. Over 7000 feet of sandstone, mudstones and halite in the Amoco Imp A-1 Osprey H-84 well on the Grand Banks of Newfoundland contain Late Triassic and Early Jurassic palynomorphs. The sequence was
deposited in an environment ranging from desert to marginal sabkha. There may have been a possible connect ion with the Tethys embayment, which developed between the Grand Banks and Iberian Peninsula in the Late Triassic. A marine transgression in the Hettangian-Sinemurian resulted in the deposition
of carbonates, which are immediately overlain by marine Upper Cretaceous elastics and marls. The regional geology indicates that deposition occurred in the Jurassic and Lower Cretaceous, the sediments being subsequently removed during uplift of the area in pre-Cenomanian time. The Tertiary sediments
are fine grained elastics becoming coarser upwards, and range in age from Eocene to Miocene.

Re-definition and subdivision of the Rapitan Group, Mackenzie Mountains
Authors: Eisbacher G H
Published: March 2016

The Proterozoic Rapitan Group of the Mackenzie Mountains has been subdivided into four formations, from bottom to top as fallows: Sayunei, Shezal, Twitya, and Keele. The Keele Formation has been included in the redefined Rapitan Group because of a gradual
transition between the Twitya Formation and f acies variations of the Keele Formation. Thickness changes, facies patterns, and sedimentary environments suggest that the basal Sayunei Formation was deposited in fault controlled basins. It consists of maroon or green siltstone and argillite and is
interbedded with sharpclast-siltstones shed from tectonic scarps. The Shezal Formation consists of glacial-marine diamictites deposited in a relatively shallow marine environment. The Twitya Formation is composed of shale and sandstone laid down on an unstable prograding shelf. The Keele Formation
is a varied assemblage of cyclic carbonates and elastics which was deposited on shallow-water banks. It grades laterally into deeper-water facies comprising mass-flow deposits. The role of contemporaneous faulting during the initial stages of Rapitan deposition i s significant in the appraisal of
stratabound copper and iron deposits of the Mackenzie Mountains.
Distribution of foraminifera in Chaleur Bay, Gulf of St. Lawrence
Authors: Schafer C T , Cole F E
Published: March 2016

The total population of foraminifera in the Chaleur Bay-Restigouche estuary system reflects the observed bathymetry, water mass characteristics and general circulation pattern. The increase in arenaceous species below 16 m in the bay probably defines the lower
limit of the seasonally-influenced and highly perturbed shallow bay environment. Dense living and total populations are indicative of ecotones in the bay near zones characterized by high primary production rates where food material is readily available. The highest species diversity occurs at
intermediate depths (40-70 m) in comparatively stable environmental conditions. These conditions are superimposed on regional (north-south) changes in substrate type and in water mass characteristics. Using cluster analyses (Q-mode) of a total percentage data matrix it is possible to define shallow
upper estuarine, near shore bay-lower estuarine, and deep off shore bay biotopes.
The geology of the Orvan Brook sulphide deposit, Restigouche County, New Brunswick
Authors: Tupper W M
Published: March 2016

The Orvan Brook area lies on the northwest limb of a large northeasterly plunging anticlinorium that contains volcanic and sedimentary rocks of the Middle Ordovician Tetagouche Group. The host rocks in ascending order are quartz and feldspar augen-schists,
iron-formation, s ericite schist, graphite schist, argillite and gr eywacke, and meta-ande site. The massive sulphide zone is coextensive with the sericite schist or occurs at the contact of the sericite schist and the overlying graphitic schist. It has a maximum known thickness of 16 feet and has
been traced for a length of 8, OOO feet and a depth of 500 feet. The sulphides are massive, fine grained and banded, and consist of pyrite, sphalerite, galena, chalcopyrite, arsenopyrite, and tetrahedrite. Approximately 80 per cent of the sulphide zone is composed of pyrite. The gross relationships
between the sulphides and host rocks suggest the deposit is conformable. Detailed examination, however, reveals dis conformable features
Stratigraphy and sedimentation in the Helikian Elu Basin and Hiukitak Platform, Bathurst Inlet-Melville sound, Northwest Territories
Authors: Campbell F H A
Published: March 2016

Helikian sedimentation in the Melville Sound area commenced with deposition of the Tinney Cove Formation fanglomerate on remnant outliers of the Aphebian fluviati le Burnside River Formation and underlying Archean basement. With uplift and erosion, a hematitic,
anomalously radioactive regolith farmed on the Tinney Cove and Archean rocks. Sedimentation in the Elu Basin and adjacent Hiukitak Platfarm commenced with the deposition of fluvial trough crossbedded quartzite, grit, and conglomerate between and eventually across the pre-Ellice hills of Archean and
Aphebian rocks. Distal braided fluvial sediments are transitional into a quartz-sand dominated deltaic complex. Thin stromatolitic units, locally interstratified with oolites and aeolian-transported quartz grains, were deposited in ephemeral lagoons and embayments on the northwestern part of the
deltaic complex. Seaward of the coarse elastics, red mudstone, shale, and dolomite accumulated in the more distal parts of intermittently-exposed deltaic complex. Beyond the limits of significant terrigenous elastic sedimentation, elastic and biogenic carbonate rocks accumulated on a shallow shelf.
Gypsum interbedded with the carbonate farmed in significant quantities in quiescent parts of the carbonate shelf facies. The evaporites later dissolved and farmed a chaotic solution breccia in the Parry Bay Formation. With transgression and decreasing supply of terrigenous elastics, elastic
carbonate, accompanied by thin sheets of low-amplitude, elongate, laterally-linked domal stromatolites, was deposited over the evaporite-bearing facies. With stability in the basin, extensive tabular bioherms of this same type of stromatolite accumulated at the platfarm-basin margin on the same
low-angle paleoslope established during deposition of the Ell ice Formation. Coarse grained doloarenite and intraformational carbonate-pebble conglomerate were deposited fallowing formation of the tabular bioherm complex. A thin continuous unit of conical stromatolites farmed during a lull in coarse
elastic sedimentation, and the southern limit of this unit delineates the northern margin of the Hiukitak Plat{ arm south of Daniel Moore Bay. Reef aid stromatolite bioherms, with inter-reef distributary channels spread southwestward across the basin during renewed subsidence. These were in turn
buried beneath algal-bound fine grained carbonate in the east and coarser grained carbonate in the west, terminating deposition in the Elu Basin.
Geophysical applications of surface wave impedance measurements
Authors: Collett L S , Jensen O G
Published: March 2016

Several powerful sources of EM radiation exist to probe the electrical properties of the Earth's crust. One natural source is the MT (magnetotelluric) field, generated either by thunderstorm activity (>1 Hz) or by micropulsations (<1 Hz),
which can be considered as a distant generator of plane EM waves vertically incident on the Earth's surface. Other useful sources are the government-operated VLF (very low frequency) radio wave transmitters typically broadcasting at 20 kHz and strategically located to provide a worldwide network of
marine navigation signals and, at slightly higher frequencies, the LF (low frequency) transmitters for providing world-wide time signals (e.g. 60 kHz, WWVB). The field far from these radio transmitters is well approximated by a plane wave polarized with the magnetic field horizontal to the Earth's
surf ace. Suitable receivers measure either a ratio of horizontal to vertical field components (wavetilt) or a ratio of electric to magnetic field components (wave impedance). Airborne sensors usually measure wavetilt, whereas ground systems can measure either wavetilt or wave impedance. At any
frequency the amplitude and phase of either of these two quantities yields two pieces of information about the electrical structure of the ground. This paper reviews the necessary theory for interpreting wave impedance measurements at VLF and LF. Particular attention is paid to the source fields for
Canada, how the nature of these source fields affects the apparent resistivity and phase measurements and the possible dielectric effects created by a combination of (high frequency) x (high resistivit)l) x (high permittivity) on field measurements. The present state of interpretation for these
methods is reviewed.
Trace metal geochemistry of sediments, northeast Pacific Ocean
Authors: Bornhold B D , Tiffin D L , Currie R G
Published: March 2016

Forty-two cores from the vicinity of the Juan de Fuca and Explorer ridges in the northeast Pacific were analyzed for Zn, Cu, Pb, Ni, Co, Mo, Mn, Fe and Ca. In all but one core, the trace element concentrations tend to be less than those of average Pacific pelagic
clay. The exception is a core located northwest of Explorer Ridge which penetrated dark brown sediments at the base of the sedimentary section. These sediments have trace element abundances comparable to those found in metalliferous sediments from the East Pacific Rise and elsewhere in the eastern
equatorial Pacific. In view of the very high rates of pelagic and hemipelagic sedimentation, metal-rich sediments overlying basaltic crust are expected to be thin in the northeast Pacific or to be localized along fault scarps or near basement outcrops where hydrothermal fluids
emanate.
Engineering geology and geotechnical study of Drynoch Landslide, British Columbia
Authors: Vandine D F
Published: March 2016

Drynoch landslide, a large earthflow along Thompson River in southwestern British Columbia, has been moving slowly for many hundreds of years and for the past one hundred years has disrupted transportation facilities which cross its toe. The slide has been noted
and studied during the past century by numerous scientists and engineers. This report assimilates much of the pertinent existing data and presents an interdisciplinary engineering geology and geotechnical study of the slide based on airphoto interpretation, surf ace and subsurface site
investigations, laboratory testing, and stability analyses. The slide material is a mixture of Pleistocene glacial till. Remoulded Tertiary sediments, and Cretaceous rock fragments. The origin of the slide is related to an excess accumulation of montmorillonite-rich Tertiary sediments and clay-rich
glacial till (possibly from a remnant valley glacier), and topographic conditions suitable for instability. Drynoch landslide is probably a zonal infinite-slope type of failure, the result of highly plastic, montmorillonite-rich clay layers, the availability of groundwater, and the presence of high
pore water pressures. A suggested method to retard movement of the slide is by means of drainage wells installed to depths below the failure zones. One means of minimizing localized instability and erosion of the toe of the landslide is by toe loading.
