How to Make MP4 Smaller. Combining moving image with audio, video is one of the best mediums for expressing yourself, a point of view, or explaining something to someone. However, due to their file size, this does usually mean videos are harder to share. One prime example is when sending clips over email. Most major email providers restrict email attachments to 20 MB, so sending a video more than a few seconds long is usually impossible. This can often cause some problems in the office if you’re sending a video file to someone for work reasons. And since, over the years video quality has improved, file sizes of the clips we have on our phones are only getting bigger, and thus harder to share. There is one quick and easy fix for this, and that’s by compressing the video file slightly so that its size is greatly reduced without losing quality. Better still, it can be done for free and through your web browser, so you don’t have to download any random software off the Internet.

Fastening Wood with Screws 101: If you need to drive a flathead screw into a piece of wood quite close to an endgrain edge, and you just drive it in without pre-drilling and countersinking, you're gonna split it. And even if you do take the time to make a pilot hole, countersink it, and get the screw in without causing a split, there's no telling what will happen over time. As the wood moves or undergoes whatever stresses it encounters—let's say the two connected pieces of wood undergo shearing forces—the screw may begin to tilt, producing the split you worked to avoid. Enter a caption (optional) To solve this problem, Canadian woodworking supply company Lee Valley created these Countersunk Washers, which "prevent the normal tendency of screw heads to split stock. "These washers have a key role to play in renovations or external trim repair," they write, "since they allow you to pull warped trim into place with long screws and then finish over it.

Alzheimer’s breakthrough uses ultrasound technology - UQ News - The University of Queensland, Australia. Queensland scientists have found that non-invasive ultrasound technology can be used to treat Alzheimer’s disease and restore memory. University of Queensland researchers discovered that the innovative drug-free approach breaks apart the neurotoxic amyloid plaques that result in memory loss and cognitive decline. Welcoming the findings today at UQ’s Queensland Brain Institute, Queensland Premier Annastacia Palaszczuk said they could have a wide impact for the community.
“The Government’s $9 million investment into this technology was to drive discoveries into clinics, and today’s announcement indicates that together with the Queensland Brain Institute, it was a worthwhile investment,” Ms Palaszczuk said. “I want my Government to encourage more of this type of innovative research. “These exciting findings will hopefully be of benefit to all Australians in the future.” “I believe the work opens up an entirely novel avenue for future therapeutic treatment.” Novo tratamento do Alzheimer restaura totalmente a função da memória. Se uma pessoa tem a doença de Alzheimer, isso é geralmente o resultado de uma acumulação de dois tipos de lesões – placas amilóides e emaranhados neurofibrilares. As placas amilóides ficam entre os neurônios e criam aglomerados densos de moléculas de beta-amilóide. Os emaranhados neurofibrilares são encontrados no interior dos neurónios do cérebro, e são causados por proteínas Tau defeituosas que se aglomeram numa massa espessa e insolúvel.
Isso faz com que pequenos filamentos chamados microtúbulos fiquem torcidos, perturbando o transporte de materiais essenciais, como nutrientes e organelas. Como não temos qualquer tipo de vacina ou medida preventiva para a doença de Alzheimer – uma doença que afeta 50 milhões de pessoas em todo o mundo – tem havido uma corrida para descobrir a melhor forma de tratá-la, começando com a forma de limpar as proteínas beta-amilóide e Tau defeituosas do cérebro dos pacientes.
