Unlike most metals, it is not a good conductor of heat or electricity. This, the most common structural form of the element ( allotrope), is about as hard and brittle as gray cast iron unless it is alloyed with other metals to make it soft and ductile. At room temperature plutonium is in its α ( alpha) form. Plutonium, like most metals, has a bright silvery appearance at first, much like nickel, but it oxidizes very quickly to a dull gray, although yellow and olive green are also reported. Other sources of plutonium in the environment are fallout from numerous above-ground nuclear tests, which are now banned. Disposal of plutonium waste from nuclear power plants and dismantled nuclear weapons built during the Cold War is a nuclear-proliferation and environmental concern. Human radiation experiments studying plutonium were conducted without informed consent, and several criticality accidents, some lethal, occurred after the war. The Fat Man bombs used in the Trinity nuclear test in July 1945, and in the bombing of Nagasaki in August 1945, had plutonium cores. Producing plutonium in useful quantities for the first time was a major part of the Manhattan Project during World War II that developed the first atomic bombs. Plutonium isotopes are expensive and inconvenient to separate, so particular isotopes are usually manufactured in specialized reactors. It is a heat source in radioisotope thermoelectric generators, which are used to power some spacecraft. Plutonium-238 has a half-life of 87.7 years and emits alpha particles. The presence of plutonium-240 limits a plutonium sample's usability for weapons or its quality as reactor fuel, and the percentage of plutonium-240 determines its grade ( weapons-grade, fuel-grade, or reactor-grade). Plutonium-240 exhibits a high rate of spontaneous fission, raising the neutron flux of any sample containing it. Trace quantities arise in natural uranium-238 deposits when uranium-238 captures neutrons emitted by decay of other uranium-238 atoms.īoth plutonium-239 and plutonium-241 are fissile, meaning that they can sustain a nuclear chain reaction, leading to applications in nuclear weapons and nuclear reactors. Plutonium is the element with the highest atomic number to occur in nature. Wartime secrecy prevented the University of California team from publishing its discovery until 1948. Since uranium had been named after the planet Uranus and neptunium after the planet Neptune, element 94 was named after Pluto, which at the time was considered to be a planet as well. First, neptunium-238 ( half-life 2.1 days) was synthesized, which subsequently beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Plutonium was first synthetically produced and isolated in late 1940 and early 1941, by a deuteron bombardment of uranium-238 in the 1.5-metre (60 in) cyclotron at the University of California, Berkeley. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. The element normally exhibits six allotropes and four oxidation states. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94.

A fourth clinical trial of MRx0518 in combination with Bavencio in the first-line maintenance setting for urothelial carcinoma, done in collaboration with Merck and Pfizer, is expected to initiate in 2021. MRx0518-I-003 is in combination with preoperative radiotherapy in resectable pancreatic cancer. The study is being done in collaboration with MSD. 4D Pharma adquiere el área de producción de la leonesa Biomar y creará empleo antes de final de año La multinacional se fija en León como centro para realizar estudios clínicos e invierte 7. The Coordinating Investigator of the study is at The University of Texas MD Anderson Cancer Center, Houston, USA, with multiple additional sites in the US. MRx0518-I-002 is in combination with Keytruda in patients whose disease has previously progressed on anti-PD-1 therapies. MRx0518-I-001 is a neoadjuvant monotherapy study in a variety of solid tumours and is being conducted at Imperial College London. It is currently being evaluated in three clinical trials in patients with cancer. It’s delivered as an oral capsule and stimulates the body’s immune system, directing it to produce cytokines and immune cells that are known to attack tumours. MRx0518 is single strain live biotherapeutic product in development for the treatment of cancer. “The combination of MRx0518 with Bavencio has the potential to further enhance the positive clinical outcomes achieved by Bavencio for the significant number of patients in this treatment setting.” Following the promising data already generated in combination with checkpoint inhibitor pembrolizumab in refractory patients, and MRx0518 monotherapy data demonstrating single agent immuno-modulation presented last year at SITC, this collaboration allows us to continue to build a broad understanding of the safety and efficacy of MRx0518 across a range of solid tumors and stages of disease,” said Duncan Peyton, CEO, 4D pharma. “With this second clinical trial collaboration for MRx0518 with a leading immune checkpoint inhibitor, 4D is able to evaluate MRx0518 in a new combination and earlier treatment setting. The treatment is co-developed and co-commercialised by Merck KGaA and Pfizer.ĤD pharma intends to commence a clinical trial in 2021 to evaluate Bavencio in combination with MRx0518 as a first-line maintenance therapy for patients with locally advanced or metastatic urothelial carcinoma that has not progressed with first-line platinum-containing chemotherapy. 4D pharma has announced a clinical trial collaboration and supply agreement with Merck KGaA and Pfizer for Bavencio (avelumab), an immunotherapy approved as a first-line maintenance treatment for patients with locally advanced or metastatic urothelial carcinoma. It just seems like this band has been in the right place at the right time for the past 25 years. We built a studio in my basement, not knowing what we were doing, nailing fuckin’ sleeping bags on the wall for soundproofing.Īnd then coming out of that, winning Grammys … I don’t know. We decided to continue because we loved being a band. So he left the company and we were free to go. And we had a clause that said if he were to leave the company, we were free to go as well. He was the man that signed Nirvana to Geffen. Then we made our second record and were let out of our contact due to a “key man clause” because Gary Gersh was the president of Capitol Records. It really does, like having the band begin with a simple demo tape, which was finished right around the time Sunny Day Real Estate was breaking up, and Pat Smear hearing the tape and offering his service. Those are the things that I look back on.īut also, if there’s one common thread that’s run through the last 25 years of being in this band, it’s that everything just falls in our laps. Had I imagined that it would have become a career, I probably would have taken it a lot more seriously, way more than just six days in the studio with my friend Barrett Jones. When you made that first little Foo Fighters tape, I imagine you never thought it would get you into arenas, let alone stadiums, let alone the Rock & Roll Hall of Fame. But we were honored to be there, mostly to honor Kurt’s amazing music. Nirvana’s induction was obviously bittersweet. This will be more of a celebration, I imagine. Your first induction was an incredible evening, but you had to figure out how to actually perform and it was very emotional. Well, at 52 years-old, that’s quite a compliment. You’re one of the youngest double inductees ever, but Eric Clapton beat you by a few years. You entered the club of the double inductee. To see so many women inducted this year is impressive and encouraging. And Carole King is a big one, and the Go-Go’s. Tina Turner, obviously, deserves everything that she’s been awarded with. As he said, “I’ll have someone to hang out with.” But also, the list of artists inducted this year is very important, and encouraging. Pat’s excited that the Go-Go’s are being inducted as well. I just talked to the Go-Go’s and they are psyched. Then I realized there are two members of the Germs. We released a statement about a member of the Germs being in the Rock & Roll Hall of Fame. As I write about my childhood in Virginia leading up to joining Scream and beginning to tour the world, and then joining Nirvana, I kind of gloss over the Foo Fighters. I’ve been looking back at the last 30 years. The last few months I’ve been writing this book. Well, I was surprised and, of course, very appreciative. My manger, John Silva, who I’ve been with for 31 fuckin’ years. Hours after the news broke, Grohl called up Rolling Stone to talk about the big news and the band’s plans going forward. Like Nirvana, they’re entering the Hall in their very first year of eligibility. October 30th will likely be another unforgettable night for Grohl when the Foo Fighters are inducted. The year after that, he jammed with Joan Jett and got stoned out of his mind with her and Miley Cyrus afterward. In 2013, he donned a kimono and blond wig to induct Rush and rock out with them on “2112.” The next year, Nirvana entered the Hall of Fame in their first year of eligibility and he played their music with Krist Novoselic for the first time since Kurt Cobain died in 1994. Dave Grohl has had a lot of memorable Rock & Roll Hall of Fame nights during the past decade. If tack reducer is applied to a surface by mistake, use isopropyl alcohol to wipe away.Ĭut out a piece of film which is roughly 4-6 inches larger than the panel on all ends. It will leave enough tack to install the film properly. The haze is what creates the barrier between the film and the paint. The Tack Reducer will dry to a haze and that is what you want. Wipe the tack reducer on the entire panel but not in recessed areas and leaving 2 inches from all edges. Apply tack reducer to a clear microfiber cloth. Chrome is sensitive, the tack reducer gives us the time to reposition and handle the film for a perfect mirror finish.

Levitt was fascinated with the behaviour and actions of children on the streets of the city, seeing surreal qualities in their play. Reflecting on Levitt's approach to photography, American writer James Agee noted that 'It would be mistaken to suppose that any of the best photography is come at by intellection it is, like all art, essentially the result of an intuitive process, drawing on all that the artist is rather than on anything he thinks, far less theorises about.' Influenced by her connections to Henri Cartier-Bresson and Walker Evans and avant-garde photography and film from Europe and Russia, Levitt developed a style of street photography that captured the uncanny in the everyday. Helen Levitt's photographs are celebrated for their depiction of everyday life in New York in the 1940s and 50s.

Through his use of archival images, Willis Thomas draws connections between historical moments and contemporary life, leaving little space to remain a dispassionate observer.Ĥ. Willis Thomas' source image, a photograph taken in 1965 by photojournalist James 'Spider' Martin for The Birmingham News, shows civil rights activist Amelia Boynton Robinson being carried by fellow marchers after being teargassed and beaten by state troopers during the protest. In Amelia falling, we bear witness to the shockingly violent incursions into what was intended as a peaceful civil rights protest march in Selma, Alabama. In this uncomfortable yet compelling image, Willis Thomas asks his audience 'not to be passive but to actually think about active participation'. Hank Willis Thomas' photographic prints on mirrors are sometimes difficult to look at, but with the viewer's reflection integrated into the image they are also impossible to ignore.

Hank Willis Thomas, Amelia falling (2014) Here in this photograph, this approach is applied to the upward-facing, smiling faces of the masses, suggestive of Sievers' belief in the importance and dignity of work.ģ. Sievers' high vantage point and sharp focus in this image is informed by his rigorous formal training at the Contempora School for Applied Arts in Berlin, where he was exposed to New Objectivity. The human face of industry is captured in Sievers' photograph of the change of shifts at the Melbourne engineering works Kelly & Lewis, where a sea of men and women are shown surging into work. Soon after arriving, he established a successful practice as a photographer and received acclaim for his architectural and industrial photography. Public domain.Īfter leaving Germany in 1938 in the build-up to the Second World War, Wolfgang Sievers settled in Australia, bringing a firmly held belief in the union of art and industry, and the self-declared desire to 'assist this country through my knowledge as thanks for the freedom I can enjoy here.'

The resulting photograph contains a concentration of the moving images and projected light of the film into a vivid rectangle of white light. To make a movie, you have to sew single-shot photographic images together. Before the invention of movies was the invention of photography. In a 2016 interview the artist described the images in this series as having 'accumulated the information of many millions of small photographs that a movie consists of. When the film started, Sugimoto would open the lens shutter of his large-format camera, closing it the moment the movie ended. To produce the images, the artist directed his camera at the movie screen, or in the case of Winnetka Drive-In, Paramount (1993), the screen at a suburban drive-in theatre. Light and time are both the means and subject of Hiroshi Sugimoto's 'Drive-In Theaters' series.
