Scientists Explain Why Earth’s Magnetic North Pole Is Drifting Away From Canada Towards Siberia  Mashable India

The title compound, (C15H23N2)2[MnBr4], comprises two N-adamantyl-N'-ethyl­imidazolium cations and one tetra­hedral [MnBr4]2− anion. Next to Coulombic inter­actions, weak hydrogen bonds of the type C—H⋯Br consolidate the crystal packing, building up a three-dimensional network.

The crystal structure of (NH4)2V3O8 has been reported twice using single-crystal X-ray data [Theobald et al. (1984). J. Phys. Chem. Solids, 45, 581–587; Range et al. (1988). Z. Naturforsch. Teil B, 43, 309–317]. In both cases, the orientation of the ammonium cation in the asymmetric unit was poorly defined: in Theobald's study, the shape and dimensions were constrained for NH4+, while in Range's study, H atoms were not included. In the present study, we collected a highly redundant data set for this ternary oxide, at 0.61 Å resolution, using Ag Kα radiation. These accurate data reveal that the NH4+ cation is disordered by rotation around a non-crystallographic axis. The rotation axis coincides with one N—H bond lying in the mirror m symmetry element of space-group type P4bm, and the remaining H sites were modelled over two disordered positions, with equal occupancy. It therefore follows that the NH4+ cations filling the space available in the (001) layered structure formed by (V3O8)2– ions do not form strong N—H⋯O hydrogen bonds with the mixed-valent oxidovanadate(IV,V) anions. This feature could have consequences for the Li-ion inter­calation properties of this material, which is used as a cathode for supercapacitors.

The crystal structure of the title mol­ecular complex, [Ag2{VO2F2}2(C13H17N3O2)4]·4H2O, supported by the heterofunctional ligand tr-ad-COOH [1-(1,2,4-triazol-4-yl)-3-carb­oxy­adamantane] is reported. Four 1,2,4-triazole groups of the ligand link two AgI atoms, as well as AgI and VV centres, forming the heterobimetallic coordination cluster {AgI2(VVO2F2)2(tr)4}. VV exists as a vanadium oxofluoride anion and possesses a distorted trigonal–bipyramidal coordination environment [VO2F2N]. A carb­oxy­lic acid functional group of the ligand stays in a neutral form and is involved in hydrogen bonding with solvent water mol­ecules and VO2F2− ions of adjacent mol­ecules. The extended hydrogen-bonding network is responsible for the crystal packing in the structure.

The crystal structures of dirubidium potassium dysprosium bis­(vanadate), Rb2KDy(VO4)2, and caesium potassium gadolinium bis­(vanadate), Cs1.52K1.48Gd(VO4)2, were solved from single-crystal X-ray diffraction data. Both compounds, synthesized by the reactive flux method, crystallize in the space group Poverline{3}m1 with the glaserite structure type. VO4 tetra­hedra are linked to DyO6 or GdO6 octa­hedra by common vertices to form sheets stacking along the c axis. The large twelve-coordinate Cs+ or Rb+ cations are sandwiched between these layers in tunnels along the a and b axes, while the K+ cations, surrounded by ten oxygen atoms, are localized in cavities.

The heterobifunctional organic ligand, 3-(1,2,4-triazol-4-yl)adamantane-1-carboxyl­ate (tr-ad-COO−), was employed for the synthesis of the title silver(I) coordination polymer, {[Ag(C13H16N3O2)]·2H2O}n, crystallizing in the rare ortho­rhom­bic C2221 space group. Alternation of the double μ2-1,2,4-triazole and μ2-η2:η1-COO− (chelating, bridging mode) bridges between AgI cations supports the formation of sinusoidal coordination chains. The AgI centers possess a distorted {N2O3} square-pyramidal arrangement with τ5 = 0.30. The angular organic linkers connect the chains into a tetra­gonal framework with small channels along the c-axis direction occupied by water mol­ecules of crystallization, which are inter­linked via O—H⋯O hydrogen bonds with carboxyl­ate groups, leading to right- and left-handed helical dispositions.

The asymmetric unit of the title compound, C12H22N+·CH3O3S−, consists of three (3,5-di­methyl­adamantan-1-yl)ammonium cations, C12H22N+, and three methane­sulfonate anions, CH3O3S−. In the crystal, the cations and anions associate via N—H⋯O hydrogen bonds into layers, parallel to the (001) plane, which include large supra­molecular hydrogen-bonded rings.

In the title compound, C18H19BrFN3S, the 1,2,4-triazole ring is nearly planar with a maximum deviation of −0.009 (3) and 0.009 (4) Å, respectively, for the S-bound C atom and the N atom bonded to the bromo­fluoro­phenyl ring. The phenyl and triazole rings are almost perpendicular to each other, forming a dihedral angle of 89.5 (2)°. In the crystal, the mol­ecules are linked by weak C—H⋯π(phen­yl) inter­actions, forming supra­molecular chains extending along the c-axis direction. The crystal packing is further consolidated by inter­molecular N—H⋯S hydrogen bonds and by weak C—H⋯S inter­actions, yielding double chains propagating along the a-axis direction. The crystal studied was refined as a racemic twin.

The title compounds, [Mo(C5H5)(COCH3)(C6H12N3P)(CO)2], (1), and [Mo(C5H5)(COCH3)(C9H16N3O2P)(C6H5)2))(CO)2], (2), have been prepared by phosphine-induced migratory insertion from [Mo(C5H5)(CO)3(CH3)]. The mol­ecular structures of these complexes are quite similar, exhibiting a four-legged piano-stool geometry with trans-disposed carbonyl ligands. The extended structures of complexes (1) and (2) differ substanti­ally. For complex (1), the molybdenum acetyl unit plays a dominant role in the organization of the extended structure, joining the mol­ecules into centrosymmetrical dimers through C—H⋯O inter­actions with a cyclo­penta­dienyl ligand of a neighboring mol­ecule, and these dimers are linked into layers parallel to (100) by C—H⋯O inter­actions between the molybdenum acetyl and the cyclo­penta­dienyl ligand of another neighbor. The extended structure of (2) is dominated by C—H⋯O inter­actions involving the carbonyl groups of the acetamide groups of the DAPTA ligand, which join the mol­ecules into centrosymmetrical dimers and link them into chains along [010]. Additional C—H⋯O inter­actions between the molybdenum acetyl oxygen atom and an acetamide methyl group join the chains into layers parallel to (101).

The title compound, bis­(1,2-diphenyl-2-sulfanyl­idene­ethane­thiol­ato-κ2S,S')(1,3,5-tri­aza-7-phosphaadamantane-κP)cobalt(II) dichloromethane hemisolvate, [Co(pdt)2(PTA)]·0.5C2H4Cl2 or [Co(C14H10S2)2(C6H12N3P)]·0.5C2H4Cl2, contains two phenyl­dithiol­ene (pdt) ligands and a 1,3,5-tri­aza-7-phosphaadamantane (PTA) ligand bound to cobalt with the solvent 1,2-di­chloro­ethane mol­ecule located on an inversion center. The cobalt core exhibits an approximately square-pyramidal geometry with partially reduced thienyl radical monoanionic ligands. The supra­molecular network is consolidated by hydrogen-bonding inter­actions primarily with nitro­gen, sulfur and chlorine atoms, as well as parallel displaced π-stacking of the aryl rings. The UV–vis, IR, and CV data are also consistent with monoanionic di­thiol­ene ligands and an overall CoII oxidation state.

Invasive species, contaminants, excessive nutrient's and sediment are just some of the many factors threatening sensitive wetlands and seagrass beds.

In the structure of the title salt, second-order Jahn–Teller distortion of the coordination octa­hedra around V ions is reflected by coexistence of short V—O bonds and trans-positioned long V—F bonds, with four equatorial V—F distances being inter­mediate in magnitude. Hydrogen bonding of the anions is restricted to F-atom acceptors only, with particularly strong N–H⋯F inter­actions [N⋯F = 2.5072 (15) Å] established by axial and cis-positioned equatorial F atoms.

The title compound exhibits exceptionally weak inter­molecular C—H⋯π hydrogen bonding of the ethynyl groups, with the corresponding H⋯π separations [2.91 (2) and 3.12 (2) Å] exceeding normal vdW distances. This bonding compliments distal contacts of the CH (aliphatic)⋯π type [H⋯π = 3.12 (2)–3.14 (2) Å] to sustain supra­molecular layers.

The title compound, C14H16, exhibits exceptionally weak intermolecular C—H...π hydrogen bonding of the ethynyl groups, with the corresponding H...π separations [2.91 (2) and 3.12 (2) Å] exceeding normal vdW distances. This bonding complements distal contacts of the CH (aliphatic)...π type [H...π = 3.12 (2)–3.14 (2) Å] to sustain supramolecular layers. Hirshfeld surface analysis of the title compound suggests a relatively limited significance of the C...H/H...C contacts to the crystal packing (24.6%) and a major contribution from H...H contacts accounting 74.9% to the entire surface.

In the structure of the title salt, (C7H12N6)[VOF5], second-order Jahn–Teller distortion of the coordination octahedra around V ions is reflected by coexistence of short V—O bonds [1.5767 (12) Å] and trans-positioned long V—F bonds [2.0981 (9) Å], with four equatorial V—F distances being intermediate in magnitude [1.7977 (9)–1.8913 (9) Å]. Hydrogen bonding of the anions is restricted to F-atom acceptors only, with particularly strong N–H...F interactions [N...F = 2.5072 (15) Å] established by axial and cis-positioned equatorial F atoms. Hirshfeld surface analysis indicates that the most important interactions are overwhelmingly H...F/F...H, accounting for 74.4 and 36.8% of the contacts for the individual anions and cations, respectively. Weak CH...F and CH...N bonds are essential for generation of three-dimensional structure.

In late April, Metalla Royalty & Streaming acquired two royalties, one of which was a Gross Overriding Royalty (GOR) on NuLegacy Gold Corporation (NUG:TSX.V; NULGF:OTCQX) flagship Red Hill project, a Carlin-style deposit in Nevada's world-famous Cortez trend.

To be clear, this was a transaction between Metalla and a private company; no cash or other remuneration flowed to NuLegacy. However, this news is still exciting and thought provoking as it pertains to a potential (implied) valuation of Red Hill. So much so, that—CEO/director of Finance and Marketing—Albert Matter put out this press release highlighting it. {corporate presentation}

Metalla's news is applicable to NuLegacy for a number of reasons. Let me start by saying I know the Metalla team, I've written about the company several times (although not recently).

This is a smart, hard-working, market-savvy group, with global experience, integrity and expertise. When dealing in streams and royalties, it's all about industry connections, market knowledge and deal flow. Metalla has that and is up to its eyeballs in deal flow (deals it can make or pass on).

Takeaways on implied valuation of NuLegacy's Red Hill project?

That's why this news is so interesting. It represents a reliable, unbiased vote of confidence in NuLegacy's Red Hill project. I was able to track down the president, CEO and a director of Metalla, Mr. Brett Heath, to ask him about his team's view of NuLegacy, their management and technical teams, and the Red Hill project,

"The Red Hill project is very interesting due to its location & position within the Cortez trend of Nevada that hosts globally significant mines & projects, specifically Cortez Hills, Pipeline & Goldrush. Although many near-surface deposits have been discovered, several blind deposits similar to Goldrush have yet to be found.

"NuLegacy's Rift Anticline is a promising new drill target, a chance to discover a large, high-grade deposit. The close proximity of Red Hill to Goldrush heavily influenced our understanding of the geology at Red Hill. Specifically, it allowed us to better understand that the Rift Anticline has similar stratigraphy to Goldrush, and similar mineralization events nearby."

Investors, shareholders and analysts are trying to figure out what (if any) read-throughs there are in terms of the valuation of the Red Hill project.

From the press release:

"Valuing Gross Overriding Royalties ("GORs") is a complicated business made easier in this instance by the straightforward nature of the [transaction] …. prorating the US$4 million purchase price for the total of 2% GOR that was acquired…. values a 1% GOR in the Red Hill project at ~US$2 million."

What this valuation exercise boils down to is how does the value of a 1% GOR compare to a conventional working interest in the same project? GORs are highly case specific, so I will give a range of possibilities. Many factors make GORs unique, but a rule of thumb is that a 1% GOR equates to a 5% working interest.

However, due to the unknown terms of this particular GOR, let's assume that the 1% GOR is equal to between a 5% and 10% working interest. By extending the range higher than 5%, more conservative valuations for Red Hull are obtained. In the chart below one can see that the implied ~US$2 million paid for a 1% GOR equals C$2.8 million at the current exchange rate.

Therefore, Red Hill's indicative valuation could be viewed as C$28 million to C$56 million, or C$0.08 to C$0.15 per share. Currently, the stock's trading at C$0.07. The company has a cash balance of C$4.5 million. {see corporate presentation}. I believe the C$0.08 to C$0.15/share range is conservative because Metalla's purchase of the GOR had a built-in profit expectation. The true ascribed value of a 1% GOR on the Red Hill project might be higher than C$2.8 million.

A true vote of confidence in NuLegacy Gold

Perhaps more important than an implied (subjective) valuation of Red Hill are the following takeaways. First, Metalla not only likes Red Hill, it must also feel good about the long-term prospects for Nevada and the U.S. Metalla looks at hundreds of deals a year from all over the world. Management can, and does, invest in dozens of jurisdictions.

Yet, in April 2020, it chose the U.S., …. Nevada …. the Cortez Trend…. Second, it chose a project that's pre-maiden resource. Remember, Metalla has paid out ~C$2.8 million, but doesn't make a penny of that back unless it re-sells some or all of the GOR it acquired, or Red Hill reaches commercial production. Therefore, I argue that investing at this relatively early stage is a stamp of approval in the extensive work done to date at Red Hill.

That Metalla chose to deploy capital in a gold asset rather than a silver asset, despite the gold-silver ratio being near an all-time high (over 110 to 1) seems promising. Finally, it chose the U.S. at a time when the currencies of Mexico, Australia, Canada and others have weakened considerably vs. the U.S. dollar, making exploration cheaper in those countries. One must have conviction to choose Red Hill over dozens of public and private, pre-maiden resource, projects around the globe.

In the end, a good project in a great jurisdiction is only as prospective as its technical/management teams. NuLegacy has prudently advanced Red Hill in good times and bad. For most of NuLegacy's existence, the gold price traded between about $1,050 and $1,400/oz.

Gold price at $1,730/oz. is a game-changer….

Now gold is hovering around $1,730/oz after almost touching $1,800/oz in March. This is a game-changer for juniors like NuLegacy that have tremendous blue-sky potential, (look at neighboring mines and development projects, some of the best on the planet) but like most juniors, have limited funding to conduct aggressive drill programs in a strong gold price environment.

A savvy company betting on the Red Hill project is yet another indication that the time has come for precious metal players to become more active in M&A.

The day that Barrick commits its deep experience (and deep pockets!) to NuLegacy's Red Hill, all royalties held on that project would soar in value. Why? The timeline to potential production would be shortened, perhaps by years, (more drilling, less investor hand holding, perhaps skipping a PEA or a PFS). The scope of the project would become larger—more drilling across a wider footprint (a 108 sq. km land package).

The value of the royalties could double, triple, quadruple…. who knows? The share price at which NuLegacy gets taken out could also be meaningfully stronger. After all the company has been through, I don't think the Board would sell the company below C$0.30/share. At least not with the gold price at $1,730/oz (or higher). Readers are reminded that C$1.5 billon OceanaGold Corp. & giant natural resources fund Tocqueville own a combined 21.5% of the company.

Might there be a bidding war for NuLegacy?

In a best case example then, there could be multiple bidders for NuLegacy. This is not nearly as crazy as it sounds, especially if the gold price keeps going up, or if the next (fully funded) drill program hits the mark. If Barrick were to make a move, OceanaGold, Newmont, or even Tocqueville (they could hold out for higher price) might have something to say about it.

Those entities, and/or other mid-tiers/majors in Nevada or around the world would keep Barrick honest. Over the years NuLegacy has been in touch with several well-known names, but I never know who they're talking with at any given time. Make no mistake, Barrick is best positioned by virtue of having the most synergies with Red Hill, so it can afford to pay several more pennies per share if need be. That's how a share price of C$0.30+ becomes possible.

Bottom line, NuLegacy Gold (TSX-V: NUG) / (OTCQX: NULGF) is a high-risk exploration play, but I believe a good speculation. There's no better time to be buying high-risk exploration than when the prices of the metals being explored for are moving up.

As more attention is drawn to NuLegacy, its team, the undisputed safety of Nevada, the prolific nature of the Cortez Trend, etc., I think there's compelling relative and absolute value here that readers should consider investigating further.

The status of soil can be represented by many properties. However, how well they represent soil status depends on the level of rainfall in the area. Researchers in Spain found that in wet regions soil status is strongly linked to biological factors, such as vegetation cover and biodiversity. In drier regions, status has a stronger link to the physical properties of the soil.

Intensive care teams inside hospitals are rapidly altering the way they care for patients with COVID-19.

The changes range from new protective gear to new treatment protocols aimed at preventing deadly blood clots.

"Things are moving so fast within this pandemic, it's hard to keep up" says Dr. Angela Hewlett, an infectious diseases physician at University of Nebraska Medical Center in Omaha and medical director of the Nebraska Biocontainment Unit. To stay current, she says, ICUs are updating their practices "on an hourly basis."

"We are learning at light speed about the disease," says Dr. Craig Coopersmith , interim director of the critical care center at Emory University. "Things that previously might have taken us years to learn, we're learning in a week or two. Things that might have taken us a month to learn beforehand, we're learning in a day or two."

The most obvious changes involve measures to protect ICU doctors, nurses and staff from the virus.

"There is a true and real probability of infection," says Dr. Tiffany Osborn a critical care specialist at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis. "You have to think about everything you touch as if it burned."

So ICUs are adapting measures used at special biocontainment units like the one at the University of Nebraska. These units were designed to care for patients affected by bioterrorism or infected with particularly hazardous communicable diseases like SARS and Ebola.

The Nebraska biocontainment unit "received several patients early on in the pandemic who were medically evacuated from the Diamond Princess cruise ship," Hewlett says. But it didn't have enough beds for the large numbers of local patients who began arriving at the University of Nebraska Medical Center.

So the nurses, respiratory therapists and physicians from the biocontainment team have "fanned out and are now working within those COVID units to make sure that all of our principles and protocols are followed there as well," Hewlett says.

Those protocols involve measures like monitoring ICU staff when they remove their protective gear to make sure the virus isn't transmitted, and placing infected patients in negative pressure rooms, which draw air inward, when possible to prevent the virus from escaping.

One of the riskiest ICU procedures is inserting a breathing tube in a COVID-19 patient's airway, which creates a direct path for virus to escape from a patient's lungs. "If you're intubating a patient, that's a much higher risk than, say, going in and doing routine patient care," Hewlett says.

So ICU teams are being advised to add several layers of protection beyond a surgical mask.

Extra personal protective equipment may include an N95 respirator, goggles, a full face shield, a head hood, an impermeable isolation gown and double gloves.

In many ICUs, teams are also placing a clear plastic box or sheet over the patient's head and upper body before inserting the tube. And as a final safety measure, the doctor may guide the tube using a video camera rather than looking directly down a patient's airway.

"It usually takes 30 minutes or so in order to get all of that equipment together, to get all of the right people there," says Dr. Kira Newman, a senior resident physician at UW Medical Center in Seattle. "and that would be a particularly fast intubation."

But most changes in the ICU are in response to an ongoing flood of new information about how COVID-19 affects the body.

There's a growing understanding, for example, that the infection can cause dangerous blood clots to form in many severely ill patients. These clots can kill if they block arteries supplying the lungs or brain. But they also can prevent blood from reaching the kidneys or even a patient's arms and legs.

Clots are a known risk for all ICU patients, Cooperman says, but the frequency and severity appears much greater with COVID-19. "So we're starting them on a higher level of medicine to prevent blood clots and if somebody actually develops blood clots, we have a plan B and a plan C and a plan D," he says.

ICU teams are also recalibrating their approach to ensuring that patients are getting enough oxygen. Early in the pandemic, the idea was to put patients on mechanical ventilator quickly to make sure their oxygen levels didn't fall too far.

But with experience, doctors have found that mechanical ventilators don't seem to work as well for COVID patients as they do for patients with other lung problems. They've also learned that that many COVID-19 patients remain lucid and relatively comfortable even when the oxygen levels in their blood are extremely low.

So many specialists are now recommending alternatives to mechanical ventilation, even for some of the sickest patients. "We're really trying now to not intubate," Osborn says.

Instead, ICU teams are relying on devices that deliver oxygen through the nasal passages, or through a mask that fits tightly over the face. And there's renewed interest in an old technique to help patients breathe. It's called proning.

"Instead of them being on their back, we're turning them on their front," Osborn says. The reason, she says is to open up a part of the lung that is collapsed when a patient is on their back.

As we discussed last week on FilmWeek, entertainment industry professionals are among the hardest hit amid the stoppage of everyday work and life due to COVID-19. Whether you’re on camera or stage, or behind it, above the line or below it, production shutdowns mean that industry professionals who already rely on sporadic work as it’s available are left with few to no options for sustainable income. 

Last week, Congressman Adam Schiff and other members of Congress who represent areas with large constituencies that work in the entertainment industry sent a letter to House leaders asking them to provide relief for both freelance and contract entertainment industry workers. “The unique freelance nature of work in film, television, theater, and live music means that a large number of the professionals who make these productions possible work only sporadically—often with extended periods between paying jobs—and count on income from each project to make ends meet,” the letter said in part. “As a result, many of them can’t qualify for traditional unemployment benefits or paid emergency leave, yet will now be unable to cover their basic expenses due to lost work.” 

Today on AirTalk, Congressman Schiff joins us to talk about what relief both freelance and contract entertainment industry professionals can expect if the House passes the stimulus package that would provide financial aid to Americans during the coronavirus pandemic.
