Note to editors: There are two maps associated with this press release. Erdene Resource Development Corp. (TSX:ERD) ("Erdene" or "Company") is pleased to announce initial results from the Company's 2017 drill program at its 100%-owned Bayan Khundii Gold Project ("Bayan Khundii") in southwest Mongolia, and to announce changes to its management team in Mongolia. Highlights (see attached plan map and cross-sections for reference) Table 1. Highlights for holes drilled within Midfield Zone (see attached map and section) Since the beginning of the 2017 program, drilling at Bayan Khundii has been focused in the area between, as well as west of, the Midfield and Striker zones, with 11 drill holes completed and three additional hole extensions. The Company has also commenced drilling with a second drill rig at its Altan Nar gold-polymetallic project, 16 kilometres northwest of Bayan Khundii, where three holes have been completed targeting the high-grade gold zone intersected in Q4-2016 within the Discovery Zone (hole TND-101). Results reported today are from the first six new holes at Bayan Khundii including: two holes drilled within Midfield; two holes testing the down-dip extension of Midfield towards the Striker Zone; one west of Midfield and one hole testing a geophysical target outside of the main northeast trend. As shown in the attached plan map and cross-section, the five holes completed within the Striker-Midfield area (BKD-98 to BKD-102) were drilled on 20 to 40-metre centers and with a dip between -45 to -55 degrees oriented towards the north-northeast to intersect the mineralized zones approximately perpendicular to their interpreted orientation (dipping approximately 45 degrees to the southwest). The reconnaissance hole was drilled at -85 degrees to the north. The drilling results for Midfield are significant in that they have extended the area of gold mineralization down dip to the south. They have also begun to confirm that gold mineralization continues within the approximately 170 metre un-tested area between Striker and Midfield, the two most prominent gold mineralized zones identified to date within the 2 kilometre by 1.8 kilometre Bayan Khundii prospect area. The results also strengthen the continuity of the high gold grades reported previously in the central Midfield area, and support the observation that this area contains the most intense hydrothermal activity and the most pervasive gold mineralization at Bayan Khundii. This observation is now supported by the repeated intersection of up to 8 metre wide, high-grade gold zones centered on quartz-adularia veins (BKD-98: 111 m to 119 m; 51.0 g/t gold). Hole BKD-100 tested the western edge of Midfield and intersected intrusive syenite at shallower depths than expected, truncating the down-dip western extension in that area. However, drilling further west intersected anomalous gold in Devonian volcanics at greater depths, suggesting the intrusive bodies are relatively restricted in extent. Current drilling also confirmed that gold mineralization continues at greater depths to the south of Midfield. The intrusion intersected in previous drilling at Midfield is deepening to the south where up to 162 metres (vertical thickness) of altered and mineralized Devonian volcanic units have been intersected. The Midfield Zone is located under younger, post-mineralization cover and has provided some of the highest grades and longest, continuously mineralized intervals intersected to date. It is located approximately 200 metres north of the original discovery area, which includes the Striker and Gold Hill zones where gold mineralization is exposed at surface. An additional mineralized zone is located 600 metres northeast of the Midfield Zone where limited exploration has been completed (Northeast Zone), with the area between covered by younger Cretaceous (post mineralization) units. The reconnaissance hole drilled in the northwest portion of Bayan Khundii is one of many holes that will test targets outside the main trend of mineralization in the coming months. These holes are designed to test new concepts but also to provide data to support the Company's broader understanding of the alteration and mineralizing event. This hole was drilled 400 metres west of the Northeast Zone and 300 metres north of the Midfield Zone. While not hosting anomalous gold values, it did intersect a sequence of weak to moderately altered tuffaceous rocks and dacite intrusions, starting at 12 metres depth beneath younger cover. Locally, zones of intense silicification, mica and magnetite alteration were encountered confirming that hydrothermal fluids did penetrate this far from the known mineralized zones. Similar indications have been observed at the bottom of the most western hole (BKD-75), 300 metres west of Midfield, where the hole encountered higher gold values at the end of the hole (185 metre vertical depth), up to 0.5 g/t gold over 2 metres. Dr. Jeffrey Hedenquist and other renowned experts, including Imants Kavalieris and Dr. Khashgerel Bat-Erdene, will be visiting the project again in the coming months to continue to assist the Erdene technical team in improving its understanding of the controls on mineralization which will be used, in part, to direct the Company's reconnaissance drilling program. The initial phase of 2017 drilling includes the completion of a series of holes in the untested areas around the original discovery areas at Bayan Khundii in order to expand and increase confidence in the continuity of the following areas; between Striker and Midfield, north of Midfield, west and northeast of Striker, and between Gold Hill and Striker. As that work progresses, the second rig, which commenced drilling in late April, will complete a series of holes at the Discovery Zone at Altan Nar (16 kilometres north of Bayan Khundii) and the new Altan Arrow gold discovery (3.5 kilometres north of Bayan Khundii) before joining the drill program at Bayan Khundii in mid-May. The second rig will then begin systematically testing geophysical targets throughout the 2 kilometre by 1.8 kilometre Bayan Khundii area, while the first rig commences more detailed infill work around the new and existing high-grade zones at Midfield, Striker, and Gold Hill. As the field season progresses and results are received, the program will be refined and expanded where necessary to concentrate additional drilling around the highest priority targets at Bayan Khundii, Altan Nar and Altan Arrow. A follow-up second phase program will be defined and implemented in early Q4-2017, based on the results from the Q2-Q3 exploration program. On May 1, the Company made several changes to its management team in Mongolia, including the hiring of Jon Lyons as Vice President Regulatory Affairs and Strategy. The changes are aimed at preparing the Company for a transition into permitting and development related work in the coming months and years. The appointments include: Bayarmaa Bagabandi - Ms. Bagabandi has been appointed Chief Administrative Officer for Erdene Mongol LLC, the Company's main Mongolian subsidiary, responsible for overseeing all financial, legal and human resource responsibilities. Bayarmaa earned an MSc in International Economics from Korea's Sogang University and has been employed with the Company for the past 12 years. Bayarmaa has been involved in the administrative side of Mongolia's resource industry for the past 17 years. Jon M. L. Lyons - Mr. Lyons will take on the role of Vice President Regulatory Affairs and Strategy, responsible for managing the various government permitting processes required to advance Erdene's mineral exploration and mining projects. Jon will also be responsible for oversight of Health, Safety, Environment, and Community areas for the Company, especially to ensure compliance and cultivate shared value for all stakeholders. Most recently, Jon was with the Global Green Growth Institute as Country Representative to Mongolia. Jon has lived and worked intermittently in Mongolia and the region, including a previous posting with the Company, since 2001. Jon earned an MBA from Maastricht University and the EuroMBA consortium and a B.A. (summa cum laude) in physics and anthropology from Wheaton College, MA, and is fluent in Mongolian and Russian. Bilguun Ankhbayar - Mr. Ankhbayar has been appointed Vice President Business Development, responsible for assisting the Company's CEO in advancing Erdene's projects to development, including economic evaluations, strategic market analysis, investor and other stakeholder relations and business development in the local communities. Bilguun graduated from Saint Mary's University in Halifax, Nova Scotia in 2007 with a B.Comm in Finance. He worked in the resource investment industry in Toronto, Canada before returning to Mongolia to become CEO of the Mongolian International Banking Group (MIBG). Bilguun became a strategic advisor to Erdene in 2016, and is now taking on increased responsibilities. Erdenebileg Pagva - Mr. Pagva has been appointed Senior Representative for Bayankhongor, the province that hosts the Company's Bayan Khundii, Altan Nar and other projects. Erdenebileg's responsibilities include managing the Company's stakeholder relations in Bayankhongor, and ensuring alignment of the Company's business activities with local and regional development trends. Erdenebileg has worked in Mongolia's mineral exploration and gold mining sector for nearly 25 years, and holds a BSc in Geology and Mine Engineering from the Mongolian University of Science and Technology. In Q2-2015, Erdene conducted an initial exploration program on the southern portion of the Company's 100%-owned Khundii exploration license in southwest Mongolia. An early rock-chip sampling program revealed multiple very high-grade surface quartz veins that returned up to 4,380 g/t gold, leading to a comprehensive exploration program that has included: geological mapping; soil geochemical surveys; additional surface rock chip sampling; a ground magnetic survey; gradient array and dipole-dipole induced polarization surveys; and the completion of 11,300 meters of drilling in 96 drill holes (as of Q4-2016). In addition to this work, a series of detailed follow-up studies have also been completed, predominantly on drill core and minor surface outcrop, including: petrographic and mineralogical analyses; a fluid inclusion study; SEM gold composition analysis; Short-Wave Infra-Red Analysis (SWIR); structural analysis; and overall petrogenetic analysis. Drilling has revealed the presence of very high gold grades, with up to 306 g/t gold over 1 metre intervals, within broad mineralized envelopes, with up to 65 metres averaging 6.3 g/t gold, including 12 metres of 29 g/t gold. Detailed studies indicate the mineralized zones can be characterized as low-sulphidation, quartz-sericite (illite)-adularia type mineralization that was formed in a back-arc extensional environment. In Q1-2016, the Company concluded preliminary metallurgical test work at Bayan Khundii, indicating that gravity concentration and cyanidation of the gravity tails yielded very good overall gold recoveries for both high-grade and low-grade composites: 99% gold recovery from the high-grade composite (24.9 g/t gold), and 92% gold recovery from the low-grade composite (0.7 g/t gold). Additional metallurgical work is underway with completion anticipated in Q3. The Bayan Khundii license has a 2% net smelter returns royalty ("NSR Royalty") in favour of Sandstorm Gold Ltd., with a buy-back option to reduce the NSR Royalty to 1%. Michael MacDonald, P.Geo. (Nova Scotia), Vice President Exploration for Erdene, is the Qualified Person as that term is defined in National Instrument 43-101 and has reviewed and approved the technical information contained in this news release. All samples have been assayed at SGS Laboratory in Ulaanbaatar, Mongolia. In addition to internal checks by SGS Laboratory, the Company incorporates a QA/QC sample protocol utilizing prepared standards and blanks. Erdene's sampling protocol for drill core consisted of collection of samples over 1 metre or 2 metre intervals (depending on the lithology and style of mineralization) over the entire length of the drill hole, excluding minor post-mineral lithologies and un-mineralized granitoids. Sample intervals were based on meterage, not geological controls or mineralization. All drill core was cut in half with a diamond saw, with half of the core placed in sample bags and the remaining half securely retained in core boxes at Erdene's Bayan Khundii exploration camp. All samples were organized into batches of 30 samples including a commercially prepared standard, blank, and either a field duplicate, consisting of two 1/4 core intervals, or a laboratory duplicate. Sample batches were periodically shipped directly to SGS in Ulaanbaatar via Erdene's logistical contractor, Monrud Co. Ltd. Erdene Resource Development Corp. is a Canada-based resource company focused on the acquisition, exploration, and development of base and precious metals in underexplored and highly prospective Mongolia. In addition to Bayan Khundii and Altan Nar, the Company has three other exploration licenses and a mining license in southwest Mongolia. Other deposits and prospects within these licenses include: Khuvyn Khar - an early-stage, copper-silver porphyry project with multiple drill targets and significant copper intersections; Nomin Tal - a narrow, high grade copper-gold discovery; Zuun Mod - a large molybdenum-copper porphyry deposit; and Altan Arrow - an early-stage, high-grade, gold-silver project. In addition to the above properties, the Company has an Alliance with Teck Resources Limited on regional copper-gold exploration in the prospective Trans Altai region of southwest Mongolia.

Cretaceous volcanism occurred over a wide region of eastern Asia. Hypotheses for its development include intra-continental rifting, continental-arc magmatism, plume activities, and delamination of a previously thickened mantle lithosphere. One of the major obstacles in differentiating the above model is the lack of systematic studies of Cretaceous volcanic rocks in eastern Mongolia and far-east Russia. In this study, we address this issue by examining the timing and geochemistry of Cretaceous volcanic rocks in eastern Mongolia. Our 40Ar/39Ar dating of volcanic rocks together with the existing K-Ar ages of volcanic rocks indicate that Cretaceous volcanism in our study area occurred between 120Ma and 104Ma. Our field investigation and geochemical analysis reveal three types of volcanic rocks in the study area: (1) a bimodal series, (2) a shoshonite series, and (3) a basanite series. Geochemical analysis of the volcanic rocks indicates a highly heterogeneous source, which is characterized by a mixture of depleted, enriched and metasomatized mantle. At least three models may explain the timing, geochemistry, and regional tectonic setting of Cretaceous volcanism in eastern Mongolia: (1) partial delamination of a previously thickened mantle lithosphere generated by arc magmatism and collision tectonics, (2) back-arc extension and its related mantle upwelling due to rapid collapse of a flat subduction slab, and (3) mantle avalanche of a thick pile of cold subducted Paleo-Asian oceanic plates initially trapped at the 670-km endothermic phase transition triggered by westward Pacific subduction causing mixing of several mantle sources. Testing the above models require further studies on the spatial and temporal relationships between Cretaceous volcanism and structural history of NE Asia. In addition, a careful restoration of the position and history of past subducted slabs of the Paleo-Asian oceans may help differentiate the above competing models in the future. © 2013 International Association for Gondwana Research.

Precision of bone mineral density (BMD) measurements of spine, femur and forearm using dual energy x-ray absorptiometry (DEXA) is greatly influenced operator dependent factors. Therefore, automatic region of interest determination in DEXA is very important. This research shows new developed algorithm of automatic region of interest determination of the femur and spine. The automatic determination method can detect region of interest (ROI) of the femur and spine using image processing tools. Firstly, adaptive threshold and separation are carried out by the detection algorithm. Then, the points of ROI for femur and spine are detected. It was validated by femur and spine phantom and real patient images. Detection algorithm, validated program representation and, experiment results are presented in this paper. © 2016 IEEE.

In information services fuzzy concepts are frequently encountered because a customer or client asks a question about something which could be interpreted in many different ways, or, a document is transmitted of a type or meaning which cannot be easily allocated to a known type or category, or to a known procedure. It might take considerable inquiry to 'place' the information, or establish in what framework it should be understood. The fuzzy set theory can be used in a wide range of domains in which information is incomplete or imprecise, such as bioinformatics. In applications statistical models are used to estimate data uncertainty. But their models are describing variability and not the imprecision of individual measurement results. Therefore other models are necessary to quantify the imprecision and uncertainty. In case of fuzzy data compare Bandemer , Klir and Yuan , and Viertl . In 1987 Dubois and Prade defined an interval valued expectation of fuzzy numbers, viewing them as random sets. Carlsson and Fuller defined an interval valued mean value of fuzzy numbers . Fuller and Majlender (2000) defined a mean and variance of fuzzy numbers for weighted possibilistic distribution . They also introduced the notations of crisp weighted possibilistic mean value, variance and covariance of fuzzy numbers. Rahim and Rasoul use the trapezoidal fuzzy number with η polynomial function and they calculated a median value of a fuzzy number for probabilistic distribution , , . In this paper we redefine the types of curve-triangular and curve-trapezoidal fuzzy numbers and calculate their mean, variance, covariance, correlation coefficient, and median for weighted possibilistic distribution and compare to simple fuzzy number, , . © 2016 IEEE.

The Carboniferous Shuteen Complex, a volcano-plutonic ring complex associated with Cu-Au porphyry mineralization, is located in the Gurvansaikhan island arc terrane of South Mongolia. This paper presents new data on the petrography, major and trace element chemistry, and Sr-Nd isotopic chemistry of the Shuteen Complex. We discuss the relationship between volcanic and plutonic rocks of the complex, and consider their similarity to high-Al2O3 trondhjemite-tonalite-granodiorite and adakites. We also consider the origin, magma source, and dynamic processes of the Shuteen Complex; propose a petrogenetic model; and investigate the composition of the subducting slab and the features of arc volcanism at the time. We assess some of the magmatic processes likely to have occurred within the Shuteen Complex, such as Carboniferous slab subduction and partial melting, and examine their influence on magma composition. The Shuteen Complex is geochemically similar to adakite-type rocks. The complex is silica-saturated (SiO2 ≥ 56%), rich in Al2O3 (≥15%), MgO (<6%), Y (≤18 ppm), and Yb (≤1.9 ppm), depleted in heavy rare earth elements, rich in Sr (>400 ppm), and depleted in high field strength elements. It also has a high Sr/Y value, and (87Sr/86Sr)I < 0.7040. The Shuteen Pluton yields a well-defined isochron age of 321 ± 9 Ma, whereas the age of the Shuteen andesites is 336 ± 24 Ma. The Shuteen Complex formed within an island arc setting, and partial melting was the dominant process during petrogenesis. The primary Shuteen magma had an adakitic composition and was probably derived from the partial melting of subducting oceanic crust, possibly with minor local interaction with mantle material. The results of quantitative modelling of mass balance and partial melt equilibrium for the magma source indicate that the subducting slab contained oceanic basalt and a minor component of oceanic sediment, which together with a restite eclogite phase formed the source of the Shuteen magma. The conclusive results of this study provide new insights into the magmatic evolution of the Shuteen Complex. © 2009 Elsevier Ltd. All rights reserved.

The lack of adequate water supply and sanitation services is a major issue related to sustainable development in many parts of the developing world. New strategic planning approaches which directly address users' needs and demand-often referred to as demand-responsive, community-based or household-centred approaches-are regarded as a crucial step towards improving the situation. This paper investigates household needs and demand for improved water supply and sanitation services in peri-urban, low-income settlements, known as "ger areas", in the city of Darkhan, Mongolia. The paper is based largely on a household survey conducted in a selected ger area subdistrict in Darkhan. The results reveal a complex picture. Even if the existing situation can be regarded as largely "improved" in terms of the definitions stipulated by the Joint Monitoring Programme for water supply and sanitation, it is shown that there is a need for action nonetheless. The paper also argues that the household survey is a useful method for assessing users' needs and demand and for meeting the requirements of demand-responsive sanitation planning approaches. © 2011 Springer-Verlag.

Tectonic studies of the East Gobi Fault Zone in southeastern Mongolia reveal multiple, distinct intracontinental deformation events postdating late Paleozoic arc accretion and continental amalgamation. Metamorphic tectonites of the Tsagan Subarga and Tavan Har blocks, previously mapped as Precambrian basement, comprise a sinistral shear zone dominated by steeply-dipping, northeast-striking foliations. Field observations and petrographic analyses indicate that the protoliths of the metamorphic tectonites are Paleozoic arc volcanic and sedimentary sequences. 40Ar/39Ar step-heating analyses of minerals from pre-, syn-, and late- to post-kinematic lithologies bracket the timing of ductile sinistral shear as Late Triassic. The main phase of distributed deformation associated with cooling through amphibolite-upper greenschist-facies conditions occurred ca. 225Ma and shear zone activity waned ca. 210Ma. Cooling rates inferred from the 40Ar/39Ar data are on the order of 40-20°C Myr-1; apparent differences for the two basement blocks may reflect subsequent differential uplift during Late Jurassic-Cretaceous rifting. Relatively rapid Late Triassic cooling suggests a transtensional component to the deformation and is coincident with core complex formation in northern China. Late Triassic intraplate deformation in southeastern Mongolia is likely the result of far field forces associated with collision between Mongolian arcs and the Siberian craton (i.e. closure of the Mongol-Okhotsk ocean) and/or collisions associated with closure of the Paleotethys. The ductile shear zone has been documented over 250km along strike and has been modified by subsequent brittle deformation events in the Mesozoic and Cenozoic. © 2010 Elsevier B.V.

We studied a stable pilot flame system for a cannon type combustor of turbo-engines by adding both a frontchamber and a pilot flame chamber with an electric ignition system to the conventional two-stage system with two-stage combustion domains: a primary zone and a secondary zone. The electric ignition period was about 1 second with 2760V(theoretical) generated by Kochcroft-Welton circuit, and the fuel was butane gas. The inlet was 25m/sec and the pressure was about 400Pascal at the inlet of combustor.We set two cases for the outlet configuration: a converging nozzle and a turbine. The outlet temperature was 280C at the outlet velocity of 25m/sec, and the temperature was 230C at the outlet velocity of 12m/sec. A sufficiently large rotational speed and torque was obtained to rotate the compressor and fan of the turbine. Weanalyzed the ignition mechanism by solving two dimensional compressible Navier-Stokes equations and found that the role of the front chamberwas to maintain the pilot flame after the ignition shock. We confirmed experimentally that this system can ignite and preserve a stable pilot flame with quite high probability. © 2015 The Authors.
