Whether you work outdoors or enjoy your time out with family and friends, avoid exposure to the #sun between 10:00 am and 04:00 pm to the extent possible.

The sun’s #UV rays are the strongest during this time.

1⃣Seek shade when UV rays are the most intense, but keep in mind that shade structures such as trees, umbrellas or canopies do not offer complete protection.

Remember the shadow rule: “Watch your shadow – Short shadow, seek shade!” Image
2⃣Wear protective clothing:

A hat offers good protection for your eyes, ears, face, and the back or your neck sunglasses that provide 99% - 100% UV-A and UV-B protection will greatly reduce eye damage.

Tightly woven, loose fitting clothes will provide additional protection. Image

How to import a #3D @Blender object in @threejs project as a #gltf file?🤔

In this thread🧵, we will streamline the process into simple steps👇

#3dmodeling #webdevelopment #cg #3D #Threejs #blender
Step1⃣: Start with creating a #Threejs-Compatible #UV Mapped 3D Object in #Blender.

➡️Download a 3D model
➡️Unwrap UVs in Blender to Create a UV map
➡️Export the UV Map as a #PNG file
➡️Create the UV Image with an Image Editing Software
Step2⃣: Importing the UV Image into Blender as glTF Material.

➡️Download the KhronosGroup glTF Blender Exporter plugin
➡️In Blender, append the glTF Blender Exporter file’s glTF to a material.
➡️ In the Node Editor, connect the image and the material.

The lies 2020:

Don’t Panic, we go for #herdimmunity, #children can’t spread it and won’t be harmed

What was really
And use #schools as a tap for controlled spread. No transparency, no testing no mask

Lets spread the lie that mask simply don’t work

Here #polarisation starts driven by misinformation and intransparancy by your government. Everybody could see that the measures were nog in line with urgency.

What were they hiding? Why no #zerorisk #zerocovid with borders closed. It could be done

2020: wait we know this will
Lead to many many deaths but the #vaccin is almost here, working hard, we know the #SPIKE is a big thing, hold on #Hopium being built.

Meanwhile lets keep up the lie of children not important to monitor😢 we know from SARS they build less #antibodies lets presume they just not

Hi! we are @InafOact and we're happy to join the #CataniaResearchShow. We'll present the latest results of our projects.
Follow the whole show, we'll then pass the baton to @lottabiolab next!
#SharperNight #EuropeanResearchersNight #ERN21 #MSCANight #ERNItaly #SharperNightCatania
#SolarPhysics These images show the latest Hα and continuum image of the Sun acquired at @InafOact with a quality index equal to 1 (1 =good, 3 = bad). They provide a view of the solar chromosphere and photosphere. The observations are carried out between 8:00 and 14:00 CET/CEST.

Yesterday, after a long discussion with a close family member who is a US MD phd, we agreed that with world's best #contagion models (% masks & social interaction) available in world today, the covid take-off could at best have been predicted 7 to 10 days before it exploded...2/
2/covid #Covid Pragmatic suggestion is to ban all #Social gatherings of > 7-10 people (indoors & outdoors), till curve turns down, but don't stop economic activity (w cumplusory masking, distancing). Once curve flattens, outdoor gathering restrictions can be eased with masking
3/covid Cities/towns/urban,/semi urban; rural markets/melas areas are where there is the greatest interaction between people (mobility & personal interaction are the key parameters in these virus spread models)

I had a similar discussion in a forum recently and this was my opinion. A thread..

As long as we started monitoring COVID in Africa from Feb 2020 then there will be lots of unexplained observations.
1) The #SARSCoV2 most likely entered #Africa way before Feb 2020, probably October 2019. Unfortunately archiving of clinical #nasopharyngeal swabs is challenging, so we might not know for sure ...
2) Most Africans like so many in other parts of the world have had infections with non-#COVID19 #coronaviridiae during their lifetime so if the cross reacting #Tcell stories are to be believed then lots of people already had them and might have offered some sort of protection

Like many, I’ve had some extra fee time these days... After rebinging @theofficenbc and #theofficereunion I was inspired.

A thread of Trump’s handling of the #coronavirus (#COVID19) pandemic, as told by Michael Scott. #TheOffice
Way back in 2018, Trump decided it was a good idea to disassemble the #Pandemic Response Team – created by the Obama administration in case there was “an airborne disease that is deadly.” This can’t go wrong! #thiswaspreventable
Trump does nothing to replace this. He plays golf and insults people on Twitter – just the normal things that presidents do right?

1/ Q: Does #uvlight kill the #virus? Should I buy one of those UV sanitizing devices?

A: Certain types of UV light *might* be able to help sanitize surfaces and air, but it's still early days.

HOWEVER, UV light CANNOT kill the virus if the virus is already inside of the body.
2/ Further, it's not currently deemed safe to use so-called “UV sanitizers” on the body, because of damage to the skin or eyes, and potential links to cancer. UV-C light, the most effective at killing viruses, can give you a nasty sunburn within seconds.
3/ Bottom line: Given the potential risks of #UV light, stay away from UV products marketed for personal use.

Left to the professionals, this technology may prove safe and useful for sanitizing equipment, airplanes, and buses, but this is still TBD.
