Authors: Sarkar Shaymal , Islam Md Daharul , Muna Marwa Kashem , Rahman SM Tajdit , Hoque Md Azizul , Ghosh Parthaya
Published: March 2017

Sarcoidosis is a chronic multisystem disorder of unknown etiology characterized by formation of granulomata within affected organs and consequent distortion of their normal architecture. Typically, these are non-caseating epithelioid granulomata involving organized collections of activated macrophages and T lymphocytes. In countries where tuberculosis is endemic, sarcoidosis is often misdiagnosed and mistreated as tuberculosis. We present case report of a 47-year-old female who presented with 2 years history of recurrent, multiple nodules with occasional joint pain & fever and had received anti-tubercular therapy without any improvement. A diagnosis of sarcoidosis is made finally and she was managed accordingly.Bangladesh J Medicine Jan 2017; 28(1) : 50-52
A Finite Element Investigation into the Impact Performance of an Open-Face Motorcycle Helmet with Ventilation Slots
Authors: Liu De-Shin , Chen Yao-Te
Published: March 2017

Motorcycle helmets are essential for reducing the risk of head injuries in the event of an impact. However, during the design of helmets, a compromise must be made between user safety and user comfort. Accordingly, the present study proposes a novel open-face helmet design, in which the helmet features three ventilation slots in the upper-head region. Finite element analysis (FEA) models were constructed for both a prototype helmet design, and three traditional helmet designs (full-face, open-face, and half-face helmets). In simulating the proposed open-face helmet, this study considered three different ventilation slot widths, namely 8, 14, and 18 mm. The simulation results showed that of all the helmet designs, the half-face helmet resulted in the greatest headform acceleration (303 G). The internal ventilation helmet achieved a lower peak acceleration than that of the full-face helmet. By contrast, the proposed open-face helmet with ventilation slots resulted in the lowest acceleration, irrespective of the ventilation slot width. The 8-mm ventilation slot width resulted in the optimal impact performance level (i.e., a peak headform acceleration of 160 G). Overall, the results suggest that the proposed open-face helmet design with ventilation slots provides a promising solution for ensuring both user protection and user comfort in warm climates.

Published: March 2017

Graphene is one of the new materials which has shown a large impact on the electronic industry due to its versatile properties, such as high specific surface area, high electrical conductivity, chemical stability, and large spectrum of electrochemical properties. The graphene material-based electronic industry has provided flexible devices which are inexpensive, simple and low power-consuming sensor tools, therefore opening an outstanding new door in the field of portable electronic devices. All these attractive advantages of graphene give a platform for the development of a new generation of devices in both food and environmental applications. Lipid-based sensors have proven to be a good route to the construction of novel devices with improved characteristics, such as fast response times, increased sensitivity and selectivity, and the possibility of miniaturization for the construction of portable biosensors. Therefore, the incorporation of a lipid substrate on graphene electrodes has provided a route to the construction of a highly sensitive and selective class of biosensors with fast response times and portability of field applications for the rapid detection of toxicants in the environment and food products.
Witnessing Multipartite Entanglement by Detecting Asymmetry
Authors: Girolami Davide , Yadin Benjamin
Published: March 2017

The characterization of quantum coherence in the context of quantum information theory and its interplay with quantum correlations is currently subject of intense study. Coherence in a Hamiltonian eigenbasis yields asymmetry, the ability of a quantum system to break a dynamical symmetry generated by the Hamiltonian. We here propose an experimental strategy to witness multipartite entanglement in many-body systems by evaluating the asymmetry with respect to an additive Hamiltonian. We test our scheme by simulating asymmetry and entanglement detection in a three-qubit Greenberger–Horne–Zeilinger (GHZ) diagonal state.
Nonequilibrium Thermodynamics and Scale Invariance
Authors: Martyushev Leonid M. , Celezneff Vladimir
Published: March 2017

A variant of continuous nonequilibrium thermodynamic theory based on the postulate of the scale invariance of the local relation between generalized fluxes and forces is proposed here. This single postulate replaces the assumptions on local equilibrium and on the known relation between thermodynamic fluxes and forces, which are widely used in classical nonequilibrium thermodynamics. It is shown here that such a modification not only makes it possible to deductively obtain the main results of classical linear nonequilibrium thermodynamics, but also provides evidence for a number of statements for a nonlinear case (the maximum entropy production principle, the macroscopic reversibility principle, and generalized reciprocity relations) that are under discussion in the literature.

Authors: Franzitta Vincenzo , Catrini Pietro , Curto Domenico
Published: March 2017

The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around the island. A point absorber is present in order to exploit this source. Two scenarios are presented, with two different levels of energy production.
User-Generated Geographic Information for Visitor Monitoring in a National Park: A Comparison of Social Media Data and Visitor Survey

Published: March 2017

Protected area management and marketing require real-time information on visitors’ behavior and preferences. Thus far, visitor information has been collected mostly with repeated visitor surveys. A wealth of content-rich geographic data is produced by users of different social media platforms. These data could potentially provide continuous information about people’s activities and interactions with the environment at different spatial and temporal scales. In this paper, we compare social media data with traditional survey data in order to map people’s activities and preferences using the most popular national park in Finland, Pallas-Yllästunturi National Park, as a case study. We compare systematically collected survey data and the content of geotagged social media data and analyze: (i) where do people go within the park; (ii) what are their activities; (iii) when do people visit the park and if there are temporal patterns in their activities; (iv) who the visitors are; (v) why people visit the national park; and (vi) what complementary information from social media can provide in addition to the results from traditional surveys. The comparison of survey and social media data demonstrated that geotagged social media content provides relevant information about visitors’ use of the national park. As social media platforms are a dynamic source of data, they could complement and enrich traditional forms of visitor monitoring by providing more insight on emerging activities, temporal patterns of shared content, and mobility patterns of visitors. Potentially, geotagged social media data could also provide an overview of the spatio-temporal activity patterns in other areas where systematic visitor monitoring is not taking place.

Published: March 2017

Cancer immunotherapy has produced impressive clinical results in recent years. Despite the success of the checkpoint blockade strategies targeting cytotoxic T lymphocyte antigen 4 (CTLA-4) and programmed death receptor 1 (PD-1), a large portion of cancer patients have not yet benefited from this novel therapy. T cell immunoglobulin and mucin domain 3 (TIM-3) has been shown to mediate immune tolerance in mouse models of infectious diseases, alloimmunity, autoimmunity, and tumor Immunity. Thus, targeting TIM-3 emerges as a promising approach for further improvement of current immunotherapy. Despite a large amount of experimental data showing an immune suppressive function of TIM-3 in vivo, the exact mechanisms are not well understood. To enable effective targeting of TIM-3 for tumor immunotherapy, further in-depth mechanistic studies are warranted. These studies will also provide much-needed insight for the rational design of novel combination therapy with other checkpoint blockers. In this review, we summarize key evidence supporting an immune regulatory role of TIM-3 and discuss possible mechanisms of action.
Improvement of Scratch and Wear Resistance of Polymers by Fillers Including Nanofillers
Authors: Brostow Witold , Lobland Haley , Hnatchuk Nathalie , Perez Jose
Published: March 2017

Polymers have lower resistance to scratching and wear than metals. Liquid lubricants work well for metals but not for polymers nor for polymer-based composites (PBCs). We review approaches for improvement of tribological properties of polymers based on inclusion of fillers. The fillers can be metallic or ceramic—with obvious consequences for electrical resistivity of the composites. Distinctions between effectiveness of micro- versus nano-particles are analyzed. For example, aluminum nanoparticles as filler are more effective for property improvement than microparticles at the same overall volumetric concentration. Prevention of local agglomeration of filler particles is discussed along with a technique to verify the prevention.

Published: March 2017

Introduction: Malnutrition is a common problem among hospitalized patients. In chronic kidney disease, it affects up to 50% of the population. Undernourishment has an adverse effect on prognosis and prolongs convalescence. The aim of the study was to test the effectiveness of NRS (Nutrition Risk Screening) -2002 in the assessment of risk of malnutrition for patients hospitalized in nephrology wards. The aim was to develop clinical characteristics of malnourished patients and to assess the relationship between nutritional status and patient outcome. Methods: The analysis included 292 patients, consecutively admitted to nephrology wards. NRS-2002 was assessed in comparison to subjective global assessment. Associations with patient characteristics and outcome were evaluated. Results: Out of all the respondents, 119 patients (40%) suffered from malnutrition. The NRS-2002 showed a very strong relationship with Subjective Global Assessment (SGA) (p < 0.0001). Malnourished patients were older, were characterized by a significantly lower body mass index (BMI), and had a much longer hospitalization duration. In multiple regression analysis, the presence of malnutrition proved to be an independent predictor of the duration of hospital stay. CONCLUSIONS: Malnutrition is highly prevalent among patients hospitalized in nephrology wards, and it affects the length of hospitalization. Identification of malnourished patients and patients at serious risk of malnutrition progression allows the implementation of appropriate nutritional intervention.
High-Q Wafer Level Package Based on Modified Tri-Layer Anodic Bonding and High Performance Getter and Its Evaluation for Micro Resonant Pressure Sensor
Authors: Wang Liying , Du Xiaohui , Wang Lingyun , Xu Zhanhao , Zhang Chenying , Gu Dandan
Published: March 2017

In order to achieve and maintain a high quality factor (high-Q) for the micro resonant pressure sensor, this paper presents a new wafer level package by adopting cross-layer anodic bonding technique of the glass/silicon/silica (GSS) stackable structure and integrated Ti getter. A double-layer structure similar to a silicon-on-insulator (SOI) wafer is formed after the resonant layer and the pressure-sensitive layer are bonded by silicon direct bonding (SDB). In order to form good bonding quality between the pressure-sensitive layer and the glass cap layer, the cross-layer anodic bonding technique is proposed for vacuum package by sputtering Aluminum (Al) on the combination wafer of the pressure-sensitive layer and the resonant layer to achieve electrical interconnection. The model and the bonding effect of this technique are discussed. In addition, in order to enhance the performance of titanium (Ti) getter, the prepared and activation parameters of Ti getter under different sputtering conditions are optimized and discussed. Based on the optimized results, the Ti getter (thickness of 300 nm to 500 nm) is also deposited on the inside of the glass groove by magnetron sputtering to maintain stable quality factor (Q). The Q test of the built testing system shows that the number of resonators with a Q value of more than 10,000 accounts for more than 73% of the total. With an interval of 1.5 years, the Q value of the samples remains almost constant. It proves the proposed cross-layer anodic bonding and getter technique can realize high-Q resonant structure for long-term stable operation.
An Approach to Automated Fusion System Design and Adaptation
Authors: Fritze Alexander , Mönks Uwe , Holst Christoph-Alexander , Lohweg Volker
Published: March 2017

Industrial applications are in transition towards modular and flexible architectures that are capable of self-configuration and -optimisation. This is due to the demand of mass customisation and the increasing complexity of industrial systems. The conversion to modular systems is related to challenges in all disciplines. Consequently, diverse tasks such as information processing, extensive networking, or system monitoring using sensor and information fusion systems need to be reconsidered. The focus of this contribution is on distributed sensor and information fusion systems for system monitoring, which must reflect the increasing flexibility of fusion systems. This contribution thus proposes an approach, which relies on a network of self-descriptive intelligent sensor nodes, for the automatic design and update of sensor and information fusion systems. This article encompasses the fusion system configuration and adaptation as well as communication aspects. Manual interaction with the flexibly changing system is reduced to a minimum.

A method of dispersion of single-wall carbon nanotubes (SWNTs) in aqueous media using Congo red (CR) is proposed. Nanotubes covered with CR constitute the high capacity system that provides the possibility of binding and targeted delivery of different drugs, which can intercalate into the supramolecular, ribbon-like CR structure. The study revealed the presence of strong interactions between CR and the surface of SWNTs. The aim of the study was to explain the mechanism of this interaction. The interaction of CR and carbon nanotubes was studied using spectral analysis of the SWNT–CR complex, dynamic light scattering (DLS), differential scanning calorimetry (DSC) and microscopic methods: atomic force microscopy (AFM), transmission (TEM), scanning (SEM) and optical microscopy. The results indicate that the binding of supramolecular CR structures to the surface of the nanotubes is based on the "face to face stacking". CR molecules attached directly to the surface of the nanotubes can bind further, parallel-oriented molecules and form supramolecular and protruding structures. This explains the high CR binding capacity of carbon nanotubes. The presented system – containing SWNTs covered with CR – offers a wide range of biomedical applications.
ALMACAL II: Extreme Star Formation Rate Densities in Dusty Starbursts Revealed by ALMA 20 mas Resolution Imaging

Published: March 2017

We present ultrahigh spatial resolution (∼20 mas or 150 pc) ALMA observations of the dust continuum at 920 μm and 1.2 mm in two submillimeter sources at z = 3.442, ALMACAL–1 (A–1:

) and ALMACAL–2 (A–2:

). About half of the star formation in each of these sources is dominated by a single compact clump (FWHM size of ∼350 pc). In A–1, two additional fainter clumps are found. The star formation rate (SFR) surface densities of all these clumps are extremely high,

to

, the highest rates found in high-redshift galaxies. Given their geometry and identical redshifts, there is a possibility that A–1 and A–2 are the lensed images of a single background source that are gravitationally amplified by the blazar host. If this were the case, the effective radius of the dusty galaxy in the source plane would be

and the demagnified SFR surface density would be

∼ 10,000

, comparable with the eastern nucleus of Arp 220. Although we cannot rule out an AGN contribution, our results suggest that a significant percentage of the enormous far-IR luminosity in some dusty starbursts is extremely compact. The high

in these sources could only be measured thanks to the ultrahigh-resolution ALMA observations used in this work, demonstrating that long-baseline observations are essential to study and interpret the properties of dusty starbursts in the early Universe.
Gamma–Gamma Absorption in the γ-ray Binary System PSR B1259-63/LS 2883
Authors: Sushch Iurii , van Soelen Brian
Published: March 2017

The observed TeV light curve from the γ-ray binary PSR B1259-63/LS 2883 shows a decrease in the flux at periastron that has not been fully explained by emission mechanisms alone. This observed decrease can, however, be explained by γγ absorption due to the stellar and disk photons. We calculate the γγ absorption in PSR B1259-63/LS 2883 taking into account photons from both the circumstellar disk and star, assuming that the γ-rays originate at the position of the pulsar. The γγ absorption due to the circumstellar disk photons produces a ≈14% decrease in the flux, and there is a total decrease of ≈52% (>1 TeV) within a few days before periastron, accompanied by a hardening of the γ-ray photon index. While the γγ absorption alone is not sufficient to explain the full complexity of the H.E.S.S. γ-ray light curve, it results in a significant decrease in the predicted flux, which is coincident with the observed decrease. In addition, we have calculated an upper limit on the γγ absorption, assuming that the emission is produced at the apex of the bow shock. Future observations with CTA during the 2021 periastron passage may be able to confine the location of the emission based on the degree of γγ absorption, as well as measure the hardening of the spectrum around periastron.
Observation of a 3D Magnetic Null Point

Published: March 2017

We describe high-resolution observations of a GOES B-class flare characterized by a circular ribbon at the chromospheric level, corresponding to the network at the photospheric level. We interpret the flare as a consequence of a magnetic reconnection event that occurred at a three-dimensional (3D) coronal null point located above the supergranular cell. The potential field extrapolation of the photospheric magnetic field indicates that the circular chromospheric ribbon is cospatial with the fan footpoints, while the ribbons of the inner and outer spines look like compact kernels. We found new interesting observational aspects that need to be explained by models: (1) a loop corresponding to the outer spine became brighter a few minutes before the onset of the flare; (2) the circular ribbon was formed by several adjacent compact kernels characterized by a size of 1″–2″; (3) the kernels with a stronger intensity emission were located at the outer footpoint of the darker filaments, departing radially from the center of the supergranular cell; (4) these kernels started to brighten sequentially in clockwise direction; and (5) the site of the 3D null point and the shape of the outer spine were detected by RHESSI in the low-energy channel between 6.0 and 12.0 keV. Taking into account all these features and the length scales of the magnetic systems involved in the event, we argue that the low intensity of the flare may be ascribed to the low amount of magnetic flux and to its symmetric configuration.

In scientific and technical degrees, the opinion of the final employers on the given subjects is really important. For this reason, the Quality Committee (CQ) of the Faculty of Chemistry of the University of Barcelona prepared a survey for chemical, engineering and pharmaceutical companies asking about the academic training required by the companies. The survey consists of nine sections including items related to laboratory operations, chemical processes, calculation methods, management systems (quality, environment and safety) or general management information. In addition, at the end of each section, a question inquires the companies about the competences shown by students in the items of the section. The results were compared with that of a similar survey carried out in 2007. The scores obtained, between 2 and 3, for all the items (score: 1, not important; 2, unimportant; 3, important; 4, very important), show that companies accept the training given to our students and the competences achieved by them. However, according to their opinion, it is possible to improve this training, especially in the subjects related to management (time, information, environment, quality, safety, etc.). Therefore, surveys are a good tool for the evaluation of the training achieved in our degrees and, consequently, for improving degrees and the teaching task, according the Quality Management System implemented in the Faculty of Chemistry.

Published: March 2017

AI has been defined in different ways, including the abilities for abstract thought, understanding, communication, reasoning, learning, retaining, planning, and solving. Intelligence is most widely studied in humans, but has also been observed in animals and plants. AI is the intelligence of machines or the simulation of intelligence in machines. AI is both the intelligence of machines and the branch of Computer Science which aims to create it, through the study and design of intelligent agents or rational agents, where an intelligent agent is a system that perceives its environment and takes actions which maximize its chances of success. Achievements include constrained and well-defined problems such as games, crossword-solving and optical character recognition. Among the traits that researchers hope machines will exhibit are reasoning, knowledge, planning, learning, communication, perception, and the ability to move and manipulate objects. In the field of AI there is no consensus on how closely the brain should be simulated.

Published: March 2017

The Internet of Things (IoT) is an emerging technology that offers great opportunities that is designed to improve the quality of consumers' lives, and also to improve economic indicators and productivity of enterprises, and more efficient use of resources. IoT system refers to the use of interconnected devices and distributed subsystems to leverage data gathered by sensors and actuators in some sort of environment and to take a proper decision on a high level. In this chapter, the authors propose an approach to Microcloud-based IoT infrastructure management to provide the desired quality of IT services with rational use of IT resources. Efficiency of IT infrastructure management can be estimated by the quality of services and the management costs. The task of operational service quality management is to maintain a given level of service quality with the use of minimum IT resources amount in IoT environment. Then, the maximum efficiency can be achieved by selecting such control when actual level of service corresponds to the coordinated with business unit and can be achieved by minimal costs. The proposed approach allows the efficient use of resources for IT services provision in IoT ecosystem through the implementation of service level coordination, resource planning and service level management processes in an integrated IT infrastructure management system based on hyperconvergence and software-defined principles. The main goals of this chapter are to investigate the state of art of the IoT applications resource demands in the context of datacenter architecture deployment and to propose Microcloud-based IoT infrastructure resource control method.

While there have been an increasing number of researches done on branding and consumer behavior especially on brand personality, social status and vanity and its influence on purchase intention, there are little researches that focus on the influence of all these factors collectively on Apps purchase intention. In addition, the fact that the influence of some factors will vary from country to country could not be ignored. This chapter conceptually argues that brand personality, social status, and physical vanity are important in building luxury fashion branded Apps. While brand personality and luxury fashion branded Apps as an internal factor plays an important role in deciphering if it has an influence on an individual's Apps purchase intention for luxury fashion brands; therefore, it is important to look into how external factors have an influence on an individual. The theoretical and future research directions are discussed.
Biostratigraphy of the Labrador Shelf, part 1
Authors: Gradstein F M , Williams G L
Published: March 2017

The Labrador Shelf covers approximately 90,000 square miles and is overlain by a sedimentary wedge thickening seaward, to a maximum of 20,000 to 30,000 feet. Hydrocarbon exploration in this inhospitable region commenced in the late sixties. To date nine wells
have been drilled, of which two have been termed discoveries, and a further two may have encountered hydrocarbons. The wells discussed in the present paper are Tenneco et al. Leif E-38 drilled in 1971 and suspended at 3557 feet, and Eastcan et al. Leif M-48 and Bjarni H-81, drilled in 1973. The
oldest sediments encountered in Leif E-38 are of apparently Early Miocene age. Leif M-48, located one mile away and with a TD of 6165 feet, bottoms in basalt dated as Early Cretaceous. Bjarni H-81, approximately 130 miles to the north of the two Leif wells has a TD of 8252 feet, also penetrating the
Early Cretaceous basalt between 7400 and 8252 feet. Overlying the basalt in Bjarni H-81 is the porous "Bjarni Sandstone", which contains Early Cretaceous palynomorphs, and which has tested gas with small amounts of condensate. The "Bjarni Sandstone" is overlain by marine Upper Cretaceous
Maastrichtian rocks, in turn followed by a Cenozoic sequence. The oldest sedimentary rocks encountered in Leif M-48 are Late Cretaceous (Maastrichtian). These are succeeded by a Cenozoic sequence; the Lower Paleocene appears to be absent and part of the (younger) Miocene may be missing. The
depositional environment has shown considerable fluctuations, from nonmarine in the Early Cretaceous, to ?neritic in the Late Cretaceous-Paleocene, bathyal in the Eocene, neritic in the Oligocene-Miocene and littoral to nonmarine in the Plio-Pleistocene. Reworked microfossils are common in the
Plio-Pleistocene.

Published: March 2017

POCO satellite magnetometer data selected ta minimize the effect of magnetospheric/ionospheric disturbances have been used to make a magnetic anomaly map over western Canada and Arctic regions. Residuals were calculated relative to a thirteenth degree field
model. The rnap represents the anomaly field at an average altitude of about 500 km. Airborne magnetic data over this same area, relative to the same field model, have been upward continued to 500 km. The resulting map compares favourably with the satellite-derived map. It confirms the reality of
the general features in this latter map, and points to their lithospheric origin. Satellite data have also been used to obtain an equivalent source representation. This removes the effects of varying altitude and spurious features resulting from low data density.
A review of large scale magnetic anomalies over Canada and Arctic regions
Authors: Coles R L
Published: March 2017

Charts of magnetic field anomalies over western Canada and Arctic regions have been compiled from several three-component airborne magnetometer surveys. The approximate waveband lies between 30 and 5000 km. A magnetic feature of several thousand kilometres
wavelength dominates the region, and is probably due in major part to sources in the earth's core . Superimposed on this feature are several groups of anomalies containing wavelengths of the order of a thousand kilometres. These can be related to crustal features, and to major tectonic provinces.
Two techniques to enhance the longer wavelength anomalies have been àpplied. Polynomials fitted to survey data sets describe the long wavelength end of the waveband. Upward continuations to altitudes 50, 100, 300 and 500 km demonstrate the relations between short wavelength anomalies (of
crustal origin) and the longer wavelength anomalies.

~n sit u stress measurement program was conducted by the University of Toronto. No sand was produced during the drill stem test or pump test and we anticipate that the open hale completion will be satisfactory. Based mainly on water level recovery after pump shutdown, the formation constants of
the Basal Clastic Unit are assessed as: T (transmissivity) = 2.29 x 10-4 m2s-l (minimum value) S (storage coefficient)= 0.0036 (maximum value) With continuous pumping at 100 m3h-l, the planned design rate, the Zowes t predicted pumping level after 2,500 days (13 or 14 years on a six-month-per year
basis) is anticipated to be at elev. +354 m (222 m below ground le ve l ). The electrical power required for lifting (including 16 m of tubing .friction) is 114 to 125 kW or about 4 percent of the thermal power produced at 100 m3h-l if the water temperature is cooled from 58.5°C to 33 °C.
It is anticipated that the drawdown 1 km distant from the pumping well will be 11 m after 250 days of pumping and 33 m after 2,500 days. Cnemical analyses on water and gas samples produced during pumping is consistent with those re ported ~arlier. Salt deposition and corrosion are not
considered to be insurmountable problems. Chemical and corrosion studies are continuing. It is recomnended that we proceed into the demonstration phase with drilling of the disposal well in 1980-81 followed by design and building of a demonstration package as soon as practical
thereafter.

Gravity measurements in southern District of Keewatin and southeastern District of Mackenzie, N.W.T.
Authors: Gibb R A , Halliday D W
Published: March 2017

A total of 3 ,464 gravity stations was used to compile eight Bouguer anomaly maps (1: 500,000) which cover part of the Western Churchill Province of the Canadian Shield in southern District of Keewatin and southeastern District of Mackenzie, Northwest
Territories. Major negative anomalies in zones of high-level crust, characterized by abundant greenstones and greenschist to amphibolite facies metamorphism, are related to epizonal granitic plutons of Archean and Aphebian age. A prominent north northwesterly trending broad regional gravity low
which cuts across the dominant northeasterly trends of the Province, contains a belt of "Nueltin Lake" type post-orogenic granite of late Hudsonian age. Gravity highs are related to basic volcanic and intrusive rocks and to areas of deep-level crust, characterized by granulite or retrograded
granulite facies metamorphism, roots of batholiths and an absence of greens tones. The major feature of the gravity field, the Central Belt anomalies, crosses the area from south west to northeast. In this belt dominant gravity, magnetic, and geological trends are northeasterly and linear in sharp
contrast to marginal zones on either side in which trends appear to "wrap around" the older Slave and Superior provinces of the Shield to the northwest and southeast. These differences in trend, along with differences in crustal level, metamorphism, plutonism and tectonic style may be related to a
complex origin for Western Churchill Province by ancient plate interaction during Aphebian (Lower Proterozoic) time.
Geothermal energy from sedimentary basins
Authors: Jessop A M
Published: March 2017

Hot water from porous rocks of the Paris Basin is being used as a source of energy for heating apartment buildings. Canadian sedimentary basins are deeper and more extensive than those in France, and it is appropriate to enquire whether similar hot water is
available to heat Canadian homes. This report describes the work done in Canada and compares it with the more advanced French accomplishments. There are many similarities in the data available to the two countries, and geological conditions in Canada appear to be at least as promissing as those in
France. The population density in France is very much greater than in Canada, but the Canadian climate is the more severe. Economie factors in Canada have not yet been analyzed.
Canadian Earthquakes - 1975
Authors: Wetmiller R J
Published: March 2017

This catalogue lists 1355 earthquakes one rockburst and 75 possible or confirmed blasts in Canada and adjacent areas detected by the Canadian seismograph network in 1975. A total of 339 earthquakes were located, 266 in Canada and 73 in adjacent areas of the
United States and Greenland. Thirty-eight earthquakes in Canada had a magnitude of 4 or greater. The two largest earthquakes in Canada in 1975 occurred on western Vancouver Island on 31 March and in the Beaufort Sea on 14 June; both had magnitude~ 5.3. An additional 1092 small shocks are
described only by magnitude and by distance from the nearest seismograph station. Most earthquakes in 1975 occurred west of Vancouver Island, in the northern Yukon, on Baffin Island and in the Queen Elizabeth Islands. Twenty-eight earthquakes plus one rockburst were reported felt in Canada in 1975.
The most strongly felt earthquake occurred on 30 November in Georgia Strait just off Vancouver and was felt with intensities V and VI in several places. The text is accompanied by four epicentre maps and by isoseismal or intensity maps for six of the felt earthquakes. In addition, the located events
are listed chronologically by region in four tables; the unlocated events are listed chronologically by station code in 33 tables. Reports of earthquakes felt in Canada and adjacent areas are summarized in one table. Histograms show the distribution of epicentral distances from seven stations
recording many unlocated events.
Gravity measurements over the Queen Elizabeth Islands and polar continental margin
Authors: Sobczak L W , Weber J R
Published: March 2017

The Dominion Observatory has made about 8, 800 gravity measurements over the Queen Elizabeth Islands and Arctic Ocean between 1960-1968. Measurements were made both on land and on the sea-ice of the ocean and inter-island areas. The Bouguer anomaly field shows
that negative anomalies occur over sedimentary basins and mountainous areas, positive anomalies occur along moderately folded regions and large positive anomalies occur over the ocean. With the exception of the anomalies over the ocean and mountainous regions, the anomalies correlate well with (1)
changes in lithologies of Paleozoic and Precambrian rocks, (2) evaporite and basic rocks, and (3) changes in thicknesses of clastic and carbonate sediments. The Archipelago region west of 90"W longitude has a mean elevation of 15 m and an average Bouguer anomaly of 6 mg al and appears to be in
isostatic equilibrium. This suggests that the large thickness (10 km) of uastic sediments is compensated.
The Yellowknife Seismological Array
Authors: Manchee E B , Somers H
Published: March 2017

The United Kingdom Atomic Energy Authority, in cooperation with the Department of Mines and Technical Surveys of Canada, has established a large seismological array at Yellowknife, Northwest Territories. The purpose of the array is to investigate the possibility
that teleseismic detection and identification of underground nuclear tests anywhere in the world may be possible using a relatively small number of similar stations. The Yellowknife Array is a research and development facility, not an operational monitoring station.
Nineteen evenly spaced seismometer vaults are arranged in an asymmetrical cross, each arm of the cross being 22.5 km in length. The output of the single vertical Willmore Mark II seismometer in each vault is recorded on a separate track on magnetic tape. The large size of the array makes azimuth
searching and velocity filtering desirable and necessary in the processing of the data. The Department of Mines and Technical Surveys is in the process of acquiring digital computing facilities which will allow the magnetic tapes to be searched for all events at twice real time speeds. In addition
to the identification problem, many routine seismological problems may also be investigated by use of this new and powerful tool.
Seismic regionalization of eastern Canada
Authors: Hamilton A C
Published: March 2017

Seisrnic regionalization is defined as a rnethod of establishing earthquake risk factors using seismicity analyses supplemented, in some cases, by tectonic information Definit1ve catalogues have been published of all earthquakes known to have occurred in
historical time in eastern Canada. The se provide the basis for a statistical evaluation of the earthquake risk. Good progress has been made on compilation of a regionalization map prepared objectively by sound statistical methods. It is anticipated that intime, this map will, supersede the present
provisional map as a basis for evaluating the earthquake factors to be used for design loading in the National Building Code. Information on recent tectonic activity in eastern Canada is summarized. Although preliminary analysis of geomorphological, tide-gauge, relevelling and gravity data indicate
that postglacial crustal tilting has been, is, and should be occurring on a regional scale, much more data are needed before there is any possibility of using tectonic information to supplement seismicity analyses for the regionalization of eastern Canada.
The Deep Bay crater
Authors: Innes M J S , Pearson W J , Geuer J W
Published: March 2017

Deep Bay forms the southeastem part of Reindeer Lake in northern Saskatchewan. It is a circular, water-filled depression with a diameter of some six and a half miles, a surface elevation of 1,100 feet above mean sea level, and a depth of 720 feet; its centre lies
at longitude 102° 59.4'W, latitude 56° 24.4'N. Topographical, geological and geophysical studies, combined with the results of diamond drilling strongly indicate an origin by meteoritic impact, and !end no support to the thesis that the Deep Bay depression is geologically or structurally
controlled. The evidence suggests that the crater was formed at least 150 million years ago and had an original rim dimension of almost six miles, a rim height of 890 feet and a true depth of 2,310 feet. Deposition of Mesozoic sediments over the centuries have combined with erosional forces to
reduce the crater to its present form.
