StemRad
StemRad is an Israeli-American start-up company that develops and manufactures personal protective equipment (PPE) against ionizing radiation. Its first product was the 360 Gamma, a device that protects the user's pelvic bone marrow from gamma radiation. StemRad has also developed the StemRad MD, a protective suit designed to provide whole-body radiation protection to physicians, and the AstroRad vest for radiation protection in space, which is currently being tested on the International Space Station and is one of the primary payloads onboard NASA's Artemis 1 lunar mission. History StemRad was founded in December 2011 by Oren Milstein and Daniel Levitt. They were inspired to create the company by the Chernobyl disaster where many of the firemen and engineers, who were first on the scene, died from high doses of gamma radiation in an illness known as Acute Radiation Syndrome (ARS), also known as radiation sickness. This idea was fueled by a sense of urgency due to the growing nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artemis 1
Artemis 1, officially Artemis I and formerly Exploration Mission-1 (EM-1), was an uncrewed Moon-orbiting mission. As the first major spaceflight of NASA's Artemis program, Artemis 1 marked the return of the agency to lunar exploration originally begun as the Apollo program decades earlier. It was the first integrated flight test of the Orion spacecraft and Space Launch System (SLS) rocket. Its main objective was to test the Orion spacecraft, especially its heat shield, in preparation for subsequent Artemis missions. These missions seek to reestablish a human presence on the Moon and demonstrate technologies and business approaches needed for future scientific studies, including exploration of Mars. The Orion spacecraft for Artemis 1 was stacked on October 20, 2021, marking the first time a super-heavy-lift vehicle has been stacked inside NASA's Vehicle Assembly Building (VAB) since the final Saturn V in 1973. On August 17, 2022, the fully stacked vehicle was rolled out fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bone Marrow Failure
Bone marrow failure occurs in individuals who produce an insufficient amount of red blood cells, white blood cells or platelets. Red blood cells transport oxygen to be distributed throughout the body's tissue. White blood cells fight off infections that enter the body. Bone marrow also contains platelets, which trigger clotting, and thus help stop the blood flow when a wound occurs. Signs and symptoms The two most common signs and symptoms of bone marrow failure are bleeding and bruising. Blood may be seen throughout the gums, nose or the skin, and tend to last longer than normal. Children have a bigger chance of seeing blood in their urine or stools, which results in digestive problems with an unpleasant scent. Individuals with this condition may also encounter tooth loss or tooth decay. Chronic fatigue, shortness of breath, and recurrent colds can also be symptoms of bone marrow failure. Causes Bone marrow failure in both children and adults can be either inherited or acqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2022 Russian Invasion Of Ukraine
On 24 February 2022, in a major escalation of the Russo-Ukrainian War, which began in 2014. The invasion has resulted in tens of thousands of deaths on both sides. It has caused Europe's largest refugee crisis since World War II. An estimated 8 million Ukrainians were displaced within their country by late May and 7.8 million fled the country by 8 November 2022, while Russia, within five weeks of the invasion, experienced its greatest emigration since the 1917 October Revolution. Following the 2014 Ukrainian Revolution, Russia annexed Crimea, and Russian-backed paramilitaries seized part of the Donbas region of south-eastern Ukraine, which consists of Luhansk and Donetsk oblasts, sparking a regional war. In March 2021, Russia began a large military build-up along its border with Ukraine, eventually amassing up to 190,000 troops and their equipment. Despite the build-up, denials of plans to invade or attack Ukraine were issued by various Russian gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Threats During The 2022 Russian Invasion Of Ukraine
During the 2022 Russian invasion of Ukraine, the possibility of Russia using tactical nuclear weapons, and the risk of broader nuclear escalation, has been widely discussed by commentators and in the media. Several senior Russian politicians, including president Vladimir Putin, former president and party leader Dmitry Medvedev, and foreign minister Sergey Lavrov, have made a number of statements widely seen as threatening the use of nuclear weapons. Additionally, the Russian occupation of the Zaporizhzhia Nuclear Power Plant has led to a crisis over the safety of the plant and the risk of a nuclear disaster. Russian statements Four days after the launch of the Russian invasion, on 28 February, President Putin ordered Russia's nuclear forces to go into a "special mode of combat duty", a state of high alert. On 20 April 2022, Russia carried out its first test launch of the RS-28 Sarmat, a new long-range intercontinental ballistic missile (ICBM). Putin said the new missile could ...

Pelvis
The pelvis (plural pelves or pelvises) is the lower part of the trunk, between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis, or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs (sex organs) and the rectum, while the pelvic f ...

Zaporizhzhia Nuclear Power Plant Crisis
During the 2022 Russian invasion of Ukraine, the Zaporizhzhia Nuclear Power Plant has become the center of an ongoing nuclear safety crisis, described by Ukraine as an act of nuclear terrorism by Russia. The plant, which is the largest of its kind in Europe, has seen destruction of its infrastructure via shelling, damage to its power lines, amounting to what Ukrainian authorities call the largest situation of its kind in history. A potential disaster may exceed the scale of previous disasters at nuclear power plants. According to a report by the International Atomic Energy Agency (IAEA), "The situation in Ukraine is unprecedented. It is the first time a military conflict has occurred amid the facilities of a large, established nuclear power" program. Nuclear safety expert Attila Aszódi said that an event similar in type and scale to the Chernobyl disaster is technically and physically not possible in the Zaporizhzhia plant, while calling for urgent steps to ensure the safet ...
