Quite far away from the vestibular nuclei, in the front (i.e. Also in the medulla (besides the vestibular nucleus) is the spinal tract of V (accounting for facial numbness), the nucleus ambiguus (accounting for swallowing problems), the spinothalamic tract (contralateral numbness), and the lower portion of the inferior cerebellar peduncle as well as spinocerebellar connecting tracts (ipsilateral clumsiness). Thus there is a lot of room for variation in the areas of damage. As the diagram illustrates above, the vestibular nucleus which extends from lower pons into medulla, is also a big target because of it's length. It is about 3 cm in length and 2cm in greatest diameter, and is a big target. The medulla is the portion of the brainstem just below the pons (recognized by cerebellar peduncles), and the first cervical spinal nerve (C1). PICA is also the most common site of occlusion from propagating thrombus or embolism caused by injury to the third section of the vertebral artery, and Wallenberg's syndrome is the most common stroke caused by chiropractic manipulation (Caplan, 1986). Of these strokes, while dissection causes 15% (Kim, 2003). Because of the far more common origin from the vertebral artery, most "PICA" syndrome strokes actually areĭue to vertebral artery occlusion (Kim 2003). PICA may arise from the vertebral artery (the usual case), or as a separate branch of the basilarĪrtery.

![]() ![]() ![]() Songs like these ensure Blue Weekend never feels overwrought despite its ambition and lengthy creative process - instead, it's the kind of big, unabashedly emotional album that people make memories to, and some of Wolf Alice's most confident and fully realized music. The band's famed stylistic shifts feel more natural than ever, whether they're rocking out or harking back to their folky roots on "Safe from Heartbreak (If You Never Fall in Love)" and "No Hard Feelings," a song about acceptance that skips away from heartache with deceptive ease. "Smile"'s collage of funk, industrial, pop, and acoustic elements is muscular and vulnerable at the same time, with Rowsell snarling "I ain't ashamed of the fact that I'm sensitive," then declaring "If you don't like me/Well, that isn't f*cking relevant" soon after. Even more so than on their previous albums, Wolf Alice stretch themselves emotionally as well as musically, particularly on "How Can I Make It OK?," a striking power ballad equally indebted to Cocteau Twins and Olivia Newton-John that surges forward on a huge riff as Rowsell sings "to live in fear isn't to live at all." Though Blue Weekend is dominated by slower songs, its outbursts are just as vital. Even as they take their dream pop to epic new heights on the hauntingly seductive "Lipstick on the Glass," they're still capable of capturing tiny nuances on songs such as "Feeling Myself," where Rowsell's introspection also reflects the voyeuristic nature of witnessing someone else's self-expression. The extra time they spent polishing the album in the studio with producer Markus Dravs during the COVID-19 lockdown was well spent: though songs like the luxurious Los Angeles homage "Delicious Things" reach a massive scope quickly, Ellie Rowsell always maintains a connection with her audience as she and the band zoom in and out from intimacy to majesty with cinematic skill. In between, Blue Weekend demonstrates just how much the group's power and control have grown in the four years since Visions of a Life. Wolf Alice announce their ambitions - and their ability to deliver on them - with the vast two-part song "The Beach," which opens the set by swelling to ever-greater peaks and closes it on a sweetly philosophical note. On the band's third album, they play to the back of the arenas and stadiums these songs were designed to be performed in.

She proclaims, "I ain't ashamed in the fact that I'm sensitive, I believe that it is the perfect adjective." She confidently asserts herself, commanding the respect she demands while pushing against assumptions and stereotypes. "Smile" is a statement of purpose, an anthem of affirmations in the midst of a world trying to bring you down. Roswell's lyrics suit this new sound very well. It's a perfectly tense moment that erupts into the chorus, taking you on a rollercoaster of emotion. The verses keep the party going, with a crunchy bassline from Theo Ellis and a breathy speak-song performance from Ellie Roswell. After a brief, watery intro, the track bursts to life with a distorted guitar riff and energetic drums. The shredded guitars and pulsating percussion provide a great platform from which.

In special effects pyrotechnics, lycopodium powder and non-dairy creamer are two common means of producing safe, controlled fire effects. Enclosed paper mill areas subject to such dangers commonly maintain very high air humidities to reduce the chance of airborne paper dust explosions. Īlthough not strictly a dust, paper particles emitted during processing – especially rolling, unrolling, calendaring/slitting, and sheet-cutting – are also known to pose an explosion hazard. Efforts are underway not only to build this knowledgebase within the industry but also to share it with local fire departments, who do periodic fire-safety inspections of businesses in their districts and who can expect to answer alarms at shops or plants where AM is now part of the production mix. For example, in machining operations downstream of the AM build, excess powder liberated from porosities in the support structures can be exposed to sparks from the cutting interface. Since the advent of industrial production–scale metal powder–based additive manufacturing (AM) in the 2010s, there is growing need for more information and experience with preventing dust explosions and fires from the traces of excess metal powder sometimes left over after laser sintering or other fusion methods. A similar problem occurs in sawmills and other places dedicated to woodworking. Powdered metals (such as aluminum, magnesium, and titanium) can form explosive suspensions in air, if finely divided.Ī gigantic explosion of flour dust destroyed a mill in Minnesota on May 2, 1878, killing 14 workers at the Washburn A Mill and another four in adjacent buildings. ![]() In addition, many otherwise mundane organic materials can also be dispersed into a dangerous dust cloud, such as grain, flour, starch, sugar, powdered milk, cocoa, coffee, and pollen. Many common materials which are known to burn can generate a dust explosion, such as coal dust and sawdust. ![]() Conditions required Īftermath of 2008 explosion at Imperial Sugar in Port Wentworth, Georgia, US Historically, fatalities from dust explosions have largely been the result of secondary dust explosions. Secondary dust explosions are the result of dust accumulation inside a building being disturbed and ignited by the primary explosion, resulting in a much more dangerous uncontrolled explosion that can affect the entire structure. Primary dust explosions may occur inside process equipment or similar enclosures, and are generally controlled by pressure relief through purpose-built ducting to the external atmosphere. If the spread of flame is at subsonic speed, the phenomenon is sometimes called a " deflagration", although looser usage calls both phenomena " explosions".ĭust explosions may be classified as being either "primary" or "secondary" in nature. The sudden release of energy from a " detonation" can produce a shockwave, either in open air or in a confined space. If rapid combustion occurs in a confined space, enormous overpressures can build up, causing major structural damage and flying debris. These weapons are the most powerful non-nuclear weapons in existence. Thermobaric weapons exploit this principle by rapidly saturating an area with an easily combustible material and then igniting it to produce explosive force. They are also commonly used by special effects artists, filmmakers, and pyrotechnicians, given their spectacular appearance and ability to be safely contained under certain carefully controlled conditions. In cases when fuel plays the role of a combustible material, the explosion is known as a fuel-air explosion.ĭust explosions are a frequent hazard in coal mines, grain elevators, and other industrial environments. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen. Lab demonstration with burning lycopodium powderĪ dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. ![]() ![]() ![]() Of course, it’s a long way from recognising one object more quickly to speeding up our ability to recognise every word in a lexicon. Crucially, the fact that the people were unaware of the learning made it much more efficient, say the researchers. Afterwards, the volunteers were much faster at discriminating that particular object from the other two than if they had trained only by looking at the shapes. Later on, the scientists asked each person to repeatedly perform a different task that – without their knowledge – recreated the same pattern of brain activity. First, they asked people to identify the differences between three subtly different objects while their brains were scanned. In 2011 neuroscientists from Japan and the US claimed to have found a way to enhance the digestion of basic knowledge. In other words, there are fundamental constraints on the speed at which we can take in new information, says Andrews.īut perhaps reading isn’t the only way to ‘upload’ information to the brain. Research suggests that comprehension tends to drop drastically when people try to process more than about 500 words per minute. These techniques work for some people, but push them too far and the gaps between the words you catch become so large that the text becomes impossible to understand. Andrews says that people using these speed-reading techniques are only ever processing an incomplete version of the text. PhotoReading, for instance, is a trademarked system in which the reader takes multiple ‘passes’ over a book, starting with the chapter headings and adding more and more detail with each pass. In fact, other speed-reading techniques also generally require the reader to fill in the gaps they miss. “The more they know already, the greater the degree of that fragmentary information they’ll pick up.” “I would argue that what people are doing is not actually understanding what the author has written but picking up words and phrases,” says Andrews. Providing the style of writing is familiar, a Spritz reader’s brain might still have some ability to guess any missing words and work out the meaning of a text. ![]() This may be because Spritz readers are subconsciously relying on their prior knowledge or experience to fill in any words they miss. These cues are missing from the written words presented by Spritz, which might make comprehension trickier.īut comprehension is not necessarily impossible, as fans of Spritz might argue. But if we fail to catch a word in speech we can use other cues such as intonation or the speaker’s hand gestures to fill in the gap and work out what’s being said. Spritz is asking us to process the written word at a similar pace to how we do speech, Andrews told BBC Future. Unfamiliar and long words, in particular, take more time to recognise and understand. In an analysis published after Spritz hit the headlines this year, she said that it’s the time it takes to comprehend words that can slow us down. But Sally Andrews, a professor of cognitive psychology at the University of Sydney, says that effective speed-reading isn’t quite that simple. Try Spritz for yourself, and you might agree with the company’s claims. For no extra effort, reading becomes much faster. By focusing on that box, the reader can identify each new word without having to shift their gaze. The people behind a new app called Spritz realised that the easiest way to do that is by flashing the words up, one after another, in the same small box. Many speed-reading methods involve making sure that new words are always in just the right place for the fovea to recognise. The trouble is that sometimes the new word we’re focusing on isn’t quite centred on the fovea, which slows down our ability to recognise and read it. As we read, we shift our focus from word to word – an eye motion called a saccade. The theory behind all speed-reading techniques involves getting words more efficiently to the fovea, a tiny section at the centre of the retina that gives us the sharp vision we need to accurately identify shapes, including letters. What’s the truth about speed-reading, and can technology really help? Sound too good to be true? Some academics would agree. That means you could read War and Peace in around 9 hours, and Moby Dick in a mere three-and-a-half. Some companies selling speed-reading apps have claimed recently they can help anyone exceed 1,000 words per minute. How quickly can you read? Are you the sort of person who finishes the daily newspaper before breakfast? Catches up with the gossip on social media in mere minutes? Races through the latest bestseller in a single sitting? Most of us manage to read about 200 words per minute – but in theory, we could train ourselves to digest information faster. ![]() ![]() ![]() Evidence indicates that non-O1/O139 strains are sporadically involved in cholera-like diarrheal disease (22,73,83,96,105), but rarely in outbreaks. These serologically diverse strains are abundant in estuarine environments. cholerae strains that are identical to, or closely resemble, clinical strains in biochemical characteristics, but fail to agglutinate in either anti-O1 or -O139 sera are now referred to as V. The O139 strain has become endemic in the Bengal region and is the cause of what may be known as the Eighth Cholera Pandemic (34,117). Except for the O antigen and the presence of a polysaccharide capsule, this serogroup is nearly identical to the seventh pandemic strain of V. Numerous cases were recorded in which patients had the typical symptoms of classical cholera, cholera gravis, previously only seen with the O1 serogroup. However, in 1993, a large outbreak of cholera occurred in India/Bangladesh from a new, until then unknown serogroup, O139 (3). Until recently, only the O1 serogroup was associated with cholera epidemics. Strains that are agglutinable in Inaba or Ogawa serotypes of O1 antiserum are well-documented human pathogens. Over 150 known somatic antigenic types have been identified. cholerae strains recovered from epidemic cholera cases contain a common somatic antigen and include serogroup O1 (54).
