Intracellular measurements of the resting potential were made in fibers of the frog sartorius muscle in solutions of varying salt composition and concentration to determine the effects of low ionic strength extracellular solutions on the resting potential. Changes in the glass microelectrode tip potential in low ionic strength solutions were minimized by adding ThCl4 to the extracellular solution. These experimental conditions allowed measurement of the relationship of the resting potential to the concentration of the salt in the extracellular solution by replacing it with the nonionic substance, sucrose. Substitution of sucrose for the extracellular NaCl produced a stable depolarization which was logarithmically related to the NaCl concentration. Substitution of sucrose for choline Cl, instead of NaCl, produced the same degree of depolarization. When Na salts of anions less permeable than chloride (Br, I, NO3) were used, the resting potentials in 116 mM solutions were close to those with ...
Thorium is a moderately soft, paramagnetic, bright silvery radioactive actinide metal. In the periodic table, it lies to the right of actinium, to the left of protactinium, and below cerium. Pure thorium is very ductile and, as normal for metals, can be cold-rolled, swaged, and drawn.[4] At room temperature, thorium metal has a face-centred cubic crystal structure; it has two other forms, one at high temperature (over 1360 °C; body-centred cubic) and one at high pressure (around 100 GPa; body-centred tetragonal).[4] Thorium metal has a bulk modulus (a measure of resistance to compression of a material) of 54 GPa, about the same as tins (58.2 GPa). Aluminiums is 75.2 GPa; coppers 137.8 GPa; and mild steels is 160-169 GPa.[5] Thorium is about as hard as soft steel, so when heated it can be rolled into sheets and pulled into wire.[6] Thorium is nearly half as dense as uranium and plutonium and is harder than both.[6] It becomes superconductive below 1.4 K.[4] Thoriums melting point of 1750 ...
Despite the burgeoning field of uranium-ligand multiple bonds, analogous complexes involving other actinides remain scarce. For thorium, under ambient conditions only a few multiple bonds to carbon, nitrogen, oxygen, sulfur, selenium and tellurium are reported, and no multiple bonds to phosphorus are known, reflecting a general paucity of synthetic methodologies and also problems associated with stabilising these linkages at the large thorium ion. Here we report structurally authenticated examples of a parent thorium(IV)-phosphanide (Th-PH2), a terminal thorium(IV)-phosphinidene (Th=PH), a parent dithorium(IV)-phosphinidiide (Th-P(H)-Th) and a discrete actinide-phosphido complex under ambient conditions (Th=P=Th). Although thorium is traditionally considered to have dominant 6d-orbital contributions to its bonding, contrasting to majority 5f-orbital character for uranium, computational analyses suggests that the bonding of thorium can be more nuanced, in terms of 5f- versus 6d-orbital ...
Introduction: This method was applied to form a non-absorbable complex with uranium and thorium swallowed with contaminated dust or other sources to get rid of them before absorption into the blood and discarded outside the body. A non-GIT absorbable simethicone was used in this method for the adsorption of uranium (VI) and thorium (IV) from a solution similar to the gastrointestinal tract pH medium. Materials and Methods: Accurately measured 9 mg of pure standard uranyl nitrate and simethicone emulsion in concentration range (100-300 mg) at 37±1°C for 20 min in pH ranges like the medium of the stomach and intestine then take the supernatant after centrifugation to make sure of decreasing of the concentration of uranium and thorium ions by ICP Mass Spectroscopy (ICP-MS). Results and Discussion: The data recorded for different total uranium and thorium concentrations reveal convergent behavior. Increasing simethicone concentration inside the safe dose shifts the sorption of uranium and thorium ...
Thorium is usually detected by radioactivity (due, in part, to the daughter elements such as radium). Uranium is also naturally radioactive; however, many uranium minerals are generally yellow or green and fluorescent, so if not, then suspect Th. Any radioactive mineral with a negative reaction to uranium tests is probably thorium. Thorium is usually associated with the rare earth elements and use complicated schemes to identify the element. Basically, the rare earths and thorium are precipitated as hydroxides from acid solutions. The precipitate is dissolved in HCl and precipitated as insoluble oxalates, washed, filtered and ignited to the oxides. The oxide is dissolved in H2SO4 and ignited to dryness. Dissolve the sulphates in water and precipitate Th using boiling sodium thiosulfate solution. Repeat the thiosulfate step if necessary to eliminate excess Ce, Zr, and Hf.. Infusible thorium minerals glow with exaggerated incandescence in the flame test (along with Sr, Mg, Zr, Zn, Ca - the lime ...
Thorium is also used as an alloying agent in gas tungsten arc welding (GTAW) to increase the melting temperature of tungsten electrodes and improve arc stability. The electrodes labeled EWTH-1 contain 1% thorium, while the EWTH-2 contain 2%. Thorium is a very effective radiation shield, although it has not been used for this purpose as much as lead or depleted uranium. Thorium is a fertile material for producing nuclear fuel in a breeder reactor. Uranium-thorium age dating has been used to date hominid fossils ...
Last year, Dr. Alexander Cannara wrote a letter to IEER/PSR pointing out errors and omissions in the fact sheet and requesting IEER/PSR to implement corrections. To the best of my knowledge no amendment or correction was ever issued.. This is an extended rebuttal of the claims made about thorium by Makhijani and Boyd; the entirety of their original statement is included in the rebuttal and denoted by italics.. Thorium fuel has been proposed as an alternative to uranium fuel in nuclear reactors. There are not thorium reactors, but rather proposals to use thorium as a fuel in different types of reactors, including existing light-water reactors and various fast breeder reactor designs.. It would seem that Mr. Makhijani and Ms. Boyd are unaware of the work done at Oak Ridge National Laboratory under Dr. Alvin Weinberg from 1955 to 1974 on the subject of fluid-fueled reactors, particularly those that used liquid-fluoride salts as a medium in which to sustain nuclear reactions. The ...
Quite a number of thorium-advocacy web sites can be found on the Internet; just look at the links list in the left panel at the Thorium Energy Alliance web site. The sites all tell a compelling story. By most estimates (though nobody seems to be certain), thorium is at least four times as common in the earths crust as uranium, and has the advantage of being commonly found in a single isotope, thus not requiring much purification. Thorium itself is not fissile, or spontaneously useful as an energy source, but if it is bombarded with neutrons, it can be cheaply converted to uranium-233, which is a very useful nuclear fuel. While uranium-233 can be used in nuclear bombs in pure form, in the thorium fuel cycle (especially if properly designed), it is contaminated with other isotopes and hence cannot be easily extracted to use in weapons. Plus, the decay products of the reaction are such that the waste remains radioactive for only a couple hundred years, instead of tens of thousands ...
By Mark Halper , December 4, 2012, 4:57 AM PST. SHANGHAI - Nuclear reactors based on the alternative fuel thorium will play a significant role in establishing clean power and giving the country energy independence, a key figure from the Chinese Academy of Sciences said here recently.. Jiang Mianheng, the son of Chinas former president Jiang Zemin, said that power from thorium reactors will help extract hydrogen that the country would convert to methanol, a clean burning fuel for cars.. The reactors will also provide process heat to industry, replacing CO2-emitting fossil fuels, Jiang said in an address to the Thorium Energy Conference 2012. And combined with more conventional nuclear, they will also help establish energy independence in a country that today relies heavily on imported coal and that by 2030 will import 75 percent of its oil and about 40 percent of its natural gas, according to a BP report..

Ive seen Transatomic give presentations before but never in a forum where theyd field questions from a room full of people with doctorates and masters in engineering and physical sciences. It would be interesting to see them present at a Thorium Energy Alliance Conference, which is unlikely. First, they do not intend to use thorium as a primary fuel and so presenting at TEAC would be the wrong crowd. If they did put thorium in their reactors it would be after theyve proven their waste annihilating designs and years later they wanted to show they could breed thorium too. Second, I believe that if they did present at TEAC or a similar forum that theyd get questions that theyd rather not answer. As in if presented to a crowd knowledgable on the subject the FUD from their papers would be exposed as such, and done so in a way that their fear mongering is undeniably built of straw men ...
An area about 6 miles north of Sundance, in the Bear Lodge Mountains, in Crook County, Wyo., was examined during August 1950 for thorium, uranium, and rare-earth oxides and samples were collected. Uranium is known to occur in fluorite veins and iron-manganese veins and in the igneous rocks of Tertiary age that compose the core of the Bear Lodge Mountains. The uranium content of the samples ranges from 0.001 to 0.015 percent in those from the fluorite veins, from 0.005 to 0.018 percent in those from the iron-manganese veins, and from 0.001 to 0.017 percent in those from the igneous rocks. The radioactivity of the samples is more than that expected from the uranium content. Thorium accounts for most of this discrepancy. The thorium oxide content of samples ranges from 0.07 to 0.25 percent in those from the iron-manganese veins and from 0.07 to 0.39 percent in those from the sedimentary...
Go Thorium sheds insight to its long-time study: What China is attempting is to turn the nuclear clock back to the mid-1960s, when Oak Ridge successfully operated a reactor with fuel derived from thorium and cooled with molten salts. The lab also produced detailed plans for a commercial-scale power plant. Despite considerable promise, the thorium test reactor was shut down in 1969 after about five years of operation. Research was effectively shelved when the Nixon Adminsitration decided in the 1970′s that the U.S. Nuclear industry would concentrate on a new generation of uranium-fueled, fast-breeder reactors. For a range of technical and political reasons, not least the publics fear of nuclear plants, these new uranium reactors have yet to come into widespread commercial use ...
THORIUM: energy cheaper than coal is a new book about two energy technologies that can solve global warming, sustainability, and energy poverty. Energy cheaper than coal is the only realistic way to dissuade 7 billion people in 250 countries from burning coal to make electricity.

In this thesis a detailed ab initio theoretical study of organothorium chemistry is presented. The first part is devoted to examining both the bonding in and the reaction chemistry of various substituted thorium complexes. Using the chlorine ligand as a model for the usual cyclopentadienyl groups found in these systems, we examine the bonding of hydrogen and methyl ligands to thorium. Frequent comparisons with the experimental results on similar species are made. In addition, by contrasting the bonding in the thorium complexes with the bonding in the analogous Group IVB systems, a qualitative and quantitative picture of bonding, as the atomic number of the metal becomes larger, can be obtained. The reaction chemistry is studied via two different sets of processes. In the first, the deuterium (D2) exchange reaction with a thorium-hydrogen bond is examined. Several studies have been done previously, both experimentally and theoretically, on the Group IVB exchange reactions. Hence, there is enough ...
This list of minerals containing Thorium is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Thorium mineral species. It is more useful when comparing rare species rather than common species ...
article{211470, abstract = {The capabilities of laser ablation-inductively coupled plasma-mass spectrometry for the detection of trace elements in a gel after gel electrophoresis were systematically studied. Figures of merit, such as limit of detection, linearity, and repeatability, were evaluated for various elements (Li, V, Cr, Mn, Ni, Cu, Zn, As, Se, Mo, Pd, Ag, Cd, Pt, Tl, Pb). Two ablation strategies were followed: single hole drilling, relevant for ablation of spots after two-dimensional (2-D) separations, and ablation with translation, i.e., on a line, relevant for one-dimensional (1-D) separations. This technique was applied to the detection of selenoproteins in red blood cells extracts after a 1-D separation (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) and the detection of selenium-containing proteins in yeast after 2-D electrophoresis (2-DE). The detection procedure was further improved by using the dynamic reaction cell technology, which allowed the removal of the ...

High-resolution, quantitative imaging of epidote from the Ann Mason fault block, Yerington district, Nevada, using scanning electron microscopy (SEM), X-ray fluorescence (XRF), and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) has revealed at least two types of epidote (type 1 and type 2), each with different major and trace element chemistry. Type 1 epidote is coarser grained, typically greater than 50 μm in diameter, and forms euhedral crystals that display twins and sector zones enriched in Fe, Sr, and Mn. Type 2 epidote is finer grained, typically less than 30 μm in diameter, irregularly zoned with respect to Fe and Al, and forms polycrystalline aggregates that include void space.. Two sources of intragranular compositional variability are defined in this study-one related to different generations of epidote only visible on the microscale, and the other related to crystallographic features such as sector zones and twins. Intragranular compositional variations ...

The incorporation of naturally occurring thorium isotopes in human femur bones was studied by analyzing 28 bone samples. The results show that the activity concentrations of 232Th and 230Th are in the range of the blank values resulting in an upper limit of theirs activity concentrations in human bones. The presence of 228Th can be attributed, on the basis of model calculations, to the radioactive decay of deposited 228Ra. We conclude that thorium is not detectably incorporated into human bones. ...
I was thinking one way to go would be to startup on TRU (as trichlorides) and balance with thorium (as tetrachloride) with NaCl or KCl (or both) for eutectic melting point depression. It appears such eutectics have nadirs on the low end of 300 degrees C, which is great because we get compatibility with cheaper easy to work with materials, as well as current steam cycles. (perhaps as low as 400 C primary cold leg temp). As the reactor goes through the once through cycle, fission product buildup would take over some of thoriums role in absorptions (ie we balance with fewer fertile shim) and the reactor starts to run on U233 mostly. This rids us of most of the TRU at the end of the once through operation so it will be easier to reprocess. Chlorination may not be optimal for fuel removal, but U233Cl4 is easily removed by vacuum distillation, as is ThCl4, all at much lower temperatures than for fluorides (eg LiF, ThF4), so thats fine ...

Anonymous then writes the truly funny statement: It literally would have rendered the entire fossil fuel industry of oil, gas and coal, not to mention conventional nuclear power obsolete. That is a bold conclusion, with zero facts provided to support the conclusion. Here are the important points that Anonymous must prove to support such a conclusion: how would nuclear-produced electricity make obsolete the oil and gas industry, given that oil provides transportation fuels for cars, trucks, ships, aircraft, and trains, plus lubricants, asphalts, and petrochemical feedstocks, and natural gas provides critical feedstock for agricultural and petrochemical production? That thorium nuclear-produced electricity must indeed be novel, even Nobel-Prize worthy stuff. Also, coal has many non-electricity uses, but perhaps Anonymous is not aware of such things, or he has a plan for substituting his thorium nuclear-produced electricity for those services. Here is a partial summary of non-electricity uses of ...
This thesis examines the as of yet undecided fate of thorium in Norway. The aims are to disclose its links to history and surroundings; shed light to the controversy enfolding it; divulge the true size and dimension of the topic as well as the prospects and influence of the most relevant actors; and attempt some degree of technological forecasting. For this purpose the thesis employs concepts and insights from the realm of the Large Technical Systems and the Technological Innovation Systems approaches. Therein the topic at hand is unveiled; hazy aspects and unclear roles of actors become better defined and scrutinized. The bona fide prospects of thorium in Norway become clearer, with obstacles and opportunities more clearly distinguished ...

The dispersion strengthening of 80 Nickel-20 Chromium and Udimet 500 Modified compositions was investigated with thorium oxide introduced by mechanical mixing or thermal decomposition techniques. Thermal decomposition of thorium nitrate onto 80 Nickel-20 Chromium powder produced a better degree of thorium oxide dispersion than mechanical mixing. The 100 hour rupture life stress of 80 Nickel-20 Chromium at 1800 F was increased from 1600 to 3400 psi with the addition of 5 vol.- thorium oxide. In addition, the effect of further cold deformation after extrusion on properties was investigated with 2.5 and 5 vol.- thorium oxide dispersions in 80 Nickel-20 Chromium. Author

The iron ore industry has been extremely volatile in the last six months as trade tensions mount between the USA & China. In contrast, market interest in highly radioactive uranium, and semi-radioactive thorium, is rising as producers step up extraction rates to match international demand for large scale carbon-free energy generation. Selling such high-volume, low-margin commodities in a politically complex macroeconomic environment can put pressure on firms cashflow, or even their margins. Trade finance products and expertise can help ease that pressure.
Vol. 1 (New York: Basic Books, 1966). Certain minerals containing uranium and thorium (pitchblende, chalcolite, uranite) are very active from the point of view of the emission of Becquerel rays. In a previous paper, one of us has shown that their activity is even greater than that of uranium and thorium, and has expressed the opinion that this effect was attributable to some other very active substance included in small amounts in these minerals.[2]. The study of uranium and thorium compounds has shown in fact that the property of emitting rays which make the air conducting and which affect photographic plates, is a specific property of uranium and thorium that occurs in all compounds of these metals, being weaker in proportion as the active metal in the compound is diminished. The physical state of the substances appears to have an entirely secondary importance. Various experiments have shown that the state of mixture of these substances seems to act only to vary the proportions of the active ...

10 Jan 2012 : Column 137W The current view of thorium reactor technologies from the nuclear industry is that, while the science is reasonably sound, developing reactors based on a thorium fuel cycle would carry major technological and commercial risks. The resources required to develop these technologies to the point at which they might be deployed successfully at a commercial scale are also very significant.. To date, both in the UK and elsewhere in the world, this has prevented private industry and government from investing significantly in the development of the technology. No thorium reactor design has yet been implemented as a commercial power reactor, while many either exist only on paper or have only had specific subsystems demonstrated. As an indicator of the challenge of taking this technology further, the Chinese Academy of Sciences estimates a development period of at least 20 years will be required before a demonstration thorium molten salt breeder reactor might be available..

But if youve seen this thorium ball for the 653d time, you may start wondering what exactly the ball summarizes. And what size it should be - apparently, there are different opinions here.. Does it supply all the energy needed to sustain the life you live? Does it include your yearly trip to the Bahamas? Your kilometers made for commuting? Or just the electricity to last you a lifetime? It looks so small.. Fortunately, we have David MacKays great calculations of what we actually use. A handy number is the consumption of 195 kWhs per person per day: the amount of energy used by the average affluent person, including household electricity, heating, transportation, food, energy contained in the stuff we buy: everything that fits our western lifestyle.. From here, its easy to calculate how much energy we need for a lifetime. Lets say we live 80 years. Of course, we live a bit longer, but I assume we use a bit less energy at infancy and at old age. That means we need 80 x 365 x 195 kWhs = ...

There is growing interest in the exploitation of the thorium nuclear fuel cycle as an alternative to that of uranium. As part of a wider study of the suitability of thorium dioxide (thoria) as a nuclear fuel, we have used molecular dynamics to investigate the thermal expansion, oxygen diffusion, and heat capacity of pure thoria and uranium doped (1-10%) thoria between 1500K and 3600 K. Our results indicate that the thermal performance of the thoria matrix, even when doped with 10%U, is comparable to, and possibly better than, that of UO2.. ...

Thorium reactors were proposed decades ago, but dismissed due to historical and personal considerations. Today they offer several levels of increased safety.
20 elements do not follow normal s,p,d or f orbitals. In other words, they are out of sync. 4 elements do not have d9 with s2 oebitals filled following in symc. Instead they are s10 d1. That is Cu 3d10 4s1, silver 4d10 5s1, Au 5d10 6s1, and roentgenium 6d10 7s1. Chromium has a chemical formula of (Argon) 5d6 4s1. Argon is the 1st element out of sync. Meaning it does not follow the synchronized pattern of filling the electron orbitals.

In her systematic search for other substances besides uranium salts that emitted radiation, Marie had found that the element thorium was likewise radioactive.. She was acutely aware of the importance of promptly publishing her discoveries and thus establishing her priority. Had Becquerel, two years earlier, not presented his discovery to the Académie des Sciences the day after he made it, credit for the discovery of radioactivity, and even a Nobel Prize, would instead have gone to Silvanus Thompson. Marie chose the same rapid means of publication. Her paper, giving a brief, simple account of her work, was presented for her to the Académie on April 12, 1898, by her former professor, Gabriel Lippmann.[17]. Even so, just as Thompson had been beaten by Becquerel, so Marie was beaten in the race to tell of her discovery that thorium gives off rays in the same way as uranium. Two months earlier, Gerhard Schmidt had published his own finding in Berlin.[18]. No one else in the world of physics had, ...

Any fission reactor LEAVES A MESS for future generations, including the , fast breeders. , That is true. Yet despite this, and despite the terrible problems at Fukushima, I still think nuclear reactors are better than fossil fuel alternatives such as coal and natural gas. I still hope the reactor in Georgia is completed. There is no doubt that fission reactors leave a mess for future generations but it will probably be less of a mess than alternatives because: The total mass of the mess is surprisingly small and it is concentrated in a small, well-defined area, rather than being spewed out in the air and over the landscape the way radioactive products from coal are. Nuclear power does not cause global warming. It is better to leave a pile of radioactive garbage than global warming. Posterity may be upset with us but I think they will be able to deal with the mess much better than we can. I hope they will have better technology. I am sure they will have robots far better than ours which are ...
German physicist who was prompted by Madame Curies discoveries to make his own study of radioactivity. In 1900, he observed that radium emitted both radiation and a colourless radioactive gas. The gas was accumulating inside ampules of radium. He called it radium emanation. (William Ramsay named it niton when he investigated it in 1908. This element was named radon, in 1923, the heaviest in the noble gas group.) Dorn had demonstrated one element transmuting to another, while releasing radiation. This work was continued by Boltwood and Soddy. Radon is not totally inert, as since 1962, chemists have been able to make radon compounds. In 1899, the release of a radioactive gas was detected by Ernest Rutherford and R.B. Owens from thorium (now known to be radon-220), and by the Curies from radium (radon-222).« Radon was first detected in 1899 as a radioactive gas released from samples of thorium by Ernest Rutherford and R.B. Owens. In the same year, the Curies detected a radioactive gas coming from ...

La2O3 is used to make optical glasses, to which this oxide confers increased density, refractive index, and hardness. Together with oxides of tungsten, tantalum, and thorium, La2O3 improves the resistance of the glass to attack by alkali. La2O3 is an ingredient for the manufacture of piezoelectric and thermoelectric materials. Automobile exhaust-gas converters contain La2O3.[7] La2O3 is also used in X-ray imaging intensifying screens, phosphors as well as dielectric and conductive ceramics. Gives off bright glow. La2O3 has been examined for the oxidative coupling of methane.[8]. La2O3 films can be deposited by many different methods, including chemical vapor disposition, atomic layer deposition, thermal oxidation, sputtering, and spray pyrolysis. Depositions of these films occur in a temperature range of 250-450 °C. Polycrystalline films are formed at 350 °C.[5]. La2O3 tungsten electrodes are replacing thoriated tungsten electrodes in Gas tungsten arc welding (TIG) due to safety concerns with ...
Physicists have observed signatures of radioactivity deep within Earth, enabling measurement of planet-wide thorium and uranium quantities.
Bertram Borden Boltwood was an American chemist and physicist whose studied the radioactivity of uranium and thorium, and their resulting products, which laid a foundation for the concept of isotopes. Boltwood traced each radioactive series of radioactive elements in rocks as they sequentially disintegrated into other isotopes or elements. He noted (1905) that the lead, a stable element, always found in such ores, was apparently the ending product of radioactive decay. Since each step in the decay occurs with a known half-life rate, he proposed (1907) that the ratios of the original radioactive elements to their various decay products could be used for dating rocks. Thus, with these measurements of the composition of such ores in the earths crust, the age of the planet could determined. He estimated 2.2 billion years. Overwork, stress and depression led to suicide.« [DSB gives date of death 14/15 Aug 1927. EB gives 15 Aug 1927.] ...

For example, locally (Australia) the conservative party was in power for over a decade, during which their well-known climate-deniers floated the idea of nuclear power for Australia as a wedge issue against the greens whenever climate-change got political traction. But they never did anything to prepare Australia for the requirements of building a dozen reactors across the country; training a new generation of nuclear researchers, physicists, engineers, etc, funding scholarships with top foreign nuclear research institutions, etc. Even when a decision was forced onto them, replacing an existing open-pool research reactor, they chose the least option they could, to outsource design, construction and initial operation to an Argentinian company. (Similarly, in debates, they would invoke the theoretical safety of next-gen pebble-bed reactors, the waste-burning of next-next-gen Thorium reactors, then invoke the price of the cheapest third gen PWRs). How would anyone in Australia ever trust any ...
The quick take home: Youre only self sovereign if you run your full node on a miniaturized backyard molten liquid fluoride salt thorium nuclear reactor. Sounds crazy? Read on.. When you read the White paper of Satoshi and the original ETH papers the one bad thing about both coins is the energy required to mine coins. This process will become harder and harder as we approach 2140. As we get closer to 2140 the process will require more energy. In this way, you should look at BTC mining like trying to climb up Mount Everest. When you are young it is easy to get to base camp. It is tougher to get to the Summit even when you are young. When you are older just getting to base camp seem ridiculous. When you are above 50 years old getting to the summit is nearly an impossible task because you do not have the mitochondrial power to get the job done with a falling oxygen tension. Mining BTC from 2050-2140 will be like trying to climb Everest at 60 years old. Analogy over.. ETH 2.0 is trying to solve this ...
Japans nuclear agency reported to the IAEA today that the nuclear fuel in three reactors at the Fukushima I Nuclear Power Plant likely melted through the inner containment vessels and not just their cores in the aftermath of the March 11th earthquake and tsunami.. As MoJos Kate Sheppard reported earlier today, Japan also more than doubled the estimate of the amount of radioactive materials released from Fukushima-from 370,000 to 770,000 terabecquerels.. Which makes the work of a research cruise just now underway to measure radioactivity in the ocean off Japan even more important.. This 15-day cruise is led by chief scientist Ken Buesseler of the Woods Hole Oceanographic Institution (WHOI) and members of his lab, Café Thorium. Theyre joined by researchers and technicians from around the world.. ...
