The Great Barrier Reef is in danger of losing much of its corals. Mass coral bleaching brought about by climate change damaged as much as 93 percent of the pristine coral reefs, which prodded the Australian government to set aside $1 billion to protect the world heritage site. Prime Minister Malcolm Turnbull announced the creation of a special $1 billion fund, The Reef Fund, which will focus on clean energy projects for the Great Barrier Reef's catchment areas. Turnbull said the budget is part of the $10 billion special account of the Clean Energy Finance Corporation, which will also serve as the fund manager via debt and equity in a period of 10 years. "Climate change is the greatest long-term threat to the Great Barrier Reef and to all coral reefs around the world," said Turnbull. "Australians are passionate about the Great Barrier Reef and the Turnbull government is committed to protecting it for future generations." Aside from preserving the Great Barrier Reef, the government believes that the special fund will also help boost Queensland's economy through job creation, improved farm profitability and mobilization of public and private investments. Turnbull said that improving the quality of water will have a great impact on preserving much of the reef. Clean water will mitigate outbreaks of crown-of-thorns starfish and bleaching. For this reason, the fund will invest on projects that would support clean water such as water and energy-efficient irrigation systems, pesticide sprayers and coastal sewage treatment plants. The fund will also consider investing on solar farms to decrease diesel use and other projects that support renewable energy. Turnbull also mentioned that the fund will add to the existing $461 million fund previously dedicated to the reef preservation. Greg Hunt, the government's environmental minister has acknowledged that the commitment is the largest of its kind that the Great Barrier Reef has received so far. "It's an investment in the legacy for our children, their children and our descendants," said Hunt. Last month, the Labor announced their own rescue plan for the reef by pledging $500 million that will be spread in five years. The Labor is planning on to put much of its money in research, reef management improvement and direct environmental investments. The announcement, however, did not sit well with Labor and Greens. Both are saying that this is a diversionary tactic to distract attention from the coal mines. Greens climate change spokesperson and deputy leader Larissa Waters has qualms about the announcement. "All of this money is taken from the Clean Energy Finance Corporation and the government hasn't specified how much will go to clean energy and how much will go to water quality," said Waters. © 2016 Tech Times, All rights reserved.

VANCOUVER, BC--(Marketwired - February 13, 2017) - Golden Predator Mining Corp. (TSX VENTURE: GPY)( : NTGSF)(the "Company" or "Golden Predator") is pleased to announce that it has entered into a mineral property option agreement with Precipitate Gold Corp. (TSX VENTURE: PRG) pursuant to which Golden Predator may acquire Precipitate Gold's 100% interest in certain mineral claims known as the Reef property located adjacent to the northern boundary of the 3 Aces Project in the southeast region of the Yukon Territory. The right to acquire the Property combined with the previously announced option agreement to acquire the Hy-Jay property from Bearing Resources Ltd. (see GPY NR 17-01 for additional information) will, on completion of these acquisitions, expand the 3 Aces Project to a total of 357 km² consisting of 1,734 contiguous quartz claims. For a map of Golden Predator's consolidated 3 Aces property holdings please see: http://goldenpredator.com/_resources/maps/3-aces/3Aces_Regional_20170208.pdf "With the acquisition of the Reef Project we have control of over 30 kilometers of mineralized trend along strike from the known high grade gold veins at 3 Aces. This package now includes all of the high priority critical ground that appears favorable to host orogenic veins in the emerging 3 Aces District," said Janet Lee-Sheriff, Chief Executive Officer. "This agreement and the previously announced option agreement for the Hy-Jay Project is a significant expansion of our initial land position from 225 km2 to 357 km2. We look forward to conducting detailed site work this summer on the new holdings while a robust drill program continues at the original 3 Aces property." The recently acquired Reef Property consists of 418 claims (8,490 ha or 84.9km2) and is strategically located between the 3 Aces property to the south and the recently announced Hy-Jay property to the north. All of these properties cover a similar stratigraphic package consisting primarily of coarse sandstones grading to quartz pebble conglomerates and a shale that grades into phyllite and slate of the Upper Proterozoic to Lower Cambrian Hyland Group. Historical exploration on the properties has outlined soil geochemical anomalies with similar metal signatures to the 3 Aces Central Core area and similar mineralization found at the 3 Aces property. The Reef Property property hosts a large area of anomalous gold (>25 ppb) in soil geochemistry in several clusters along a 3.2 km north-northeast trend the largest which covers 1.4 km of the trend with values ranging up to 774 ppb gold. Rock samples on the property range from below detection to a high of 2.24 g/t gold. (Precipitate Gold Corp., June 2012 Exploration Report) Previous sampling on the Hy-Jay property has outlined three areas with anomalous gold in soil geochemistry and two grab samples containing visible gold in quartz have been reported. Historically, 265 rock samples were collected from the Hy-Jay property with values ranging from below detection to 22 samples with greater than 1 g/t gold and a maximum value of 144.2 g/t gold. In the most recent exploration in 2010-2011 a new zone, the Zig Zag, was discovered which returned 47.0 g/t, 22.0 g/t and 19.9 g/t gold in float boulders of quartz-arsenopyrite-galena. (Bearing Resources Ltd., March 2012 Assessment Report on the Hy-Jay claims) In consideration for the Claims, Golden Predator will pay to the Vendor an aggregate cash payment in the amount of $1,050,000, payable over a 36 month period from the closing date of the Agreement (the "Closing Date"). In addition, Golden Predator will issue 100,000 common shares and 100,000 warrants of the Company to the Vendor upon TSXV approval, and a further 100,000 common shares and 100,000 warrants on the date that is 12 months from the Closing Date. The warrants will be exercisable for a period of three years from the Closing Date at a price of $1.50 and $2.00 respectively. Golden Predator has also agreed to issue up to $300,000 worth of common shares of the Company to the Vendor on each of 24 months and 36 months from the Closing Date, at a price per share equal to the 21-day VWAP as at the date of issuance, subject to a floor price equal to the minimum price permitted under the TSXV policies. In addition the Company will issue 300,000 warrants on the each of 24 months and 36 months from the Closing Date, with the exercise price to be equal to 150% of the 21-day VWAP as at the date of issuance, and having a three year exercise period. Pursuant to the Agreement, Golden Predator will grant to the Vendor a 2% net smelter return royalty on certain of the claims and a 1% net smelter returns royalty on the remaining claims (the "NSR"). Golden Predator may re-purchase 25% of the NSR, at any time, for the purchase price of $1,000,000, and a further 25% for a purchase price of $1,500,000. The common shares issued pursuant to this Acquisition will be subject to a four-month hold period in accordance with applicable securities laws. Upon completion of the transactions described above, the 3 Aces project will be comprised of the 3 Aces, Reef, and Hy-Jay properties consisting of 1,734 claims covering 357 km² or 35,700 hectares in southeast Yukon. The project is located along the all-season Cantung Mine Road which accesses the Cantung Mine located 40 km to the north. To date, the 3 Aces Project, which includes the two highest grade surface outcrops discovered to date in the Yukon, has 30 mineralized veins which have been discovered through sampling, trenching, roadwork and drilling with different gold bearing veins occurring throughout 762 m (2,500 feet) of vertical elevation within the Central Core area. Surface outcrops of gold bearing quartz veins were first discovered on the property in 2009. The project was advanced with extensive soil sampling, which outlined significant gold-in-soil anomalies over a Central Core Area of 10.5 km2, and helicopter supported core drilling. Previous exploration work by Golden Predator in 2015 and 2016, which includes metallurgical studies, rotary air blast (RAB) drilling, RC drilling and bulk sampling, focused on establishing the grade and continuity of the Ace of Spades vein where previous diamond drilling had intersected the vein but returned lower than expected grades. The work in 2015 and 2016 confirmed the high grades of the vein by utilizing a sampling protocol derived from the metallurgical studies that are resulting in a better estimation of gold grades within the veins. In 2016, Golden Predator concluded its Q4 drill program with 4,315 m and will recommence drilling in February 2017. Drill results have been released from the Spades Zone with results pending from the Clubs and Hearts Zones. The 3 Aces property is located in the traditional territory of the Kaska Nation. In January 2013, Golden Predator signed an Exploration Agreement with the Kaska Nation, as represented by the Ross River Dena Council and the Liard First Nation, with respect to activities within their traditional territories. The 3 Aces project operates under a Class 4 Mining Land Use Permit. The technical content of this news release has been reviewed and approved by Mike Burke, P Geo, a Qualified Person as defined by National Instrument 43-101 and an employee of the Company. Golden Predator Mining Corp., a well-financed Canadian gold mineral exploration company is expanding surface discoveries, at its 3 Aces project in Canada's Yukon, through focused drilling. The 3 Aces property is a high-grade gold in quartz project with an exploration program underway that includes sampling, trenching, drilling and bulk sampling to define and interpret the project.

Tucked away in the northern Caribbean, Anguilla is a shy beauty with a warm smile. A slender length of coral and limestone fringed with green, the island is ringed with 33 beaches, considered by savvy travelers and top travel magazines, to be the most beautiful in the world. Anguilla lies just off the beaten path, so it has retained a charming character and exclusivity. Yet because it can be conveniently reached from two major gateways: St Martin and Puerto Rico, and by private air, it's a hop and a skip away. Romance? Barefoot elegance? Unfussy chic? And untrammeled bliss? Anguilla is the answer.

A significant difference between the behavior in tension versus compression is obtained at the polycrystal level if either twinning or non-Schmid effects are contributors to the plastic deformation at the single crystal level. Examples of materials that exhibit tension-compression asymmetry include hexagonal close-packed (HCP) polycrystals and intermetallics (e.g., molybdenum compounds). Despite recent progress in modeling their yield behavior in the absence of voids, the description of coupling between plasticity and damage by void growth in these materials remains a challenge. This paper is devoted to the development of a macroscopic anisotropic yield criterion for a porous material when the matrix material is incompressible, anisotropic and displays tension-compression asymmetry. The analytical yield criterion is obtained based on micromechanical considerations and non-linear homogenization. The matrix plastic behavior is described by the Cazacu et al. (2006) anisotropic yield criterion that is pressure-insensitive and accounts for strength-differential effects. Comparison between finite element cell calculations and theory show the predictive capabilities of the developed anisotropic model in terms of modeling the combined effects of anisotropy, tension-compression asymmetry of the matrix and voids on the overall yielding of the porous aggregate. It is shown that if the matrix material does not display tension-compression asymmetry, the developed criterion reduces to that of Benzerga and Besson (2001). If the matrix is isotropic, it reduces to the isotropic criterion developed in Cazacu and Stewart (2009). © 2010 Elsevier Ltd. All rights reserved.

In this paper, the combined effects of texture and asymmetric single-crystal plastic deformation mechanisms on the dilatational response of voided polycrystals are assessed for the first time. To this end, a full-field dilatational viscoplastic Fast Fourier Transform (FFT)-based approach is used to generate gauge surfaces for porous polycrystals deforming by twinning at single crystal level, which are compared to yield surfaces obtained according to a recent analytical criterion for porous materials. Both approaches are cross-validated, revealing unusual features of the dilatational response, namely, a lack of symmetry of the surfaces with respect to both the hydrostatic and deviatoric axes. This strong sensitivity to the third invariant of the stress deviator is associated to the anisotropy and the tension-compression asymmetry of the plastic response of the matrix. © 2012 Elsevier Ltd.

Pop recording artist J.W. CUDD will debut his "Angel Artifacts" collection at Entertainment Weekly's PopFest. The event will take place on October 29th & 30th at The Reef in Downtown Los Angeles. Centered around the hottest entertainment in pop culture, Entertainment Weekly will be bringing fans face-to-face with artists, performances, movies, book signings, and live podcasts. A few of the celebrity headliners include Jennifer Aniston, Nick Jonas, Anna Faris, Stephen Amell, JoJo, James Corden, and more. Although known for his music and acting, CUDD will be showcasing a new shade of creativity: Art. "I've always been passionate about creating — whether it be singing, songwriting, acting, or various art mediums. Like any musician who has to find their sound, I believe that every painter has to find their style. After eight years of serious soul-searching, I was finally able to unearth what resonated within me." Cudd noted. With a collection resembling thousands of vibrantly colored butterflies, J.W. CUDD's "Angel Artifacts" portrays a positive vibration by representing the evolution of humanity throughout the Earth & Cosmos. Constructed with a layer of sea salt and glossy wings, the metaphysical nature of CUDD radiates onto his work. In an interview with Gas Mask Magazine CUDD stated, "I wanted to create something that would inspire — something that would make everyone come together. That was the motive behind Angel Artifacts. The larger pieces contain more than 3,000 butterflies, and after clocking in almost two years of work, I'm excited to unveil this collection to viewers. They were made with light, and I hope people see them for the beauty they resemble." The Texas native has currently been promoting a few projects this fall, including his latest music video "BOOMERANG" and the movie "LISTEN". The music video reflects a vibrant world filled with color, karma, and the GasMaskMagazine.com logo — which CUDD exclusively designed for the company. Written by CUDD and produced by multi-platinum record producer, Andrew Lane (Miley Cyrus, Backstreet Boys, Kelly Rowland), the song is laced with hooky melodies and pop-induced synths. "BOOMERANG" is now available on iTunes.

Strength differential effects (different behavior in tension versus compression) are observed at the polycrystal level, if either twinning or non-Schmid type slip are contributors to plastic deformation at the single crystal level. Despite recent progress in modeling the effects of this asymmetry on the plastic flow of the fully dense polycrystal, modeling the response of such polycrystals in the presence of voids remains a challenge. The aim of this paper is to numerically assess the influence of the tension-compression asymmetry of the plastic flow in the matrix (solid material) on void evolution and the location of the zone corresponding to maximum damage in round tensile specimens subject to uniaxial tension. It is shown that if the matrix tensile strength is higher than its compressive strength, void growth and damage distribution are similar to that in classical materials obeying Gurson's criterion. On the other hand, for certain porous polycrystals in which the matrix tensile strength is lower than its compressive strength, the rate of void growth rate is much slower. Damage distribution is significantly different, the location of the zone of maximum porosity shifts from the center of the specimen outwards. Furthermore, void growth is significantly affected by the rate of change of the tension-compression asymmetry of the matrix with accumulated plastic strain. © 2012 Elsevier Masson SAS.
