#avgeek #planespotting #USNavy #USAF #USMC: Douglas SBD Dauntless / A-24 Banshee carrier-borne and land-based dive-bomber saw extensive action in the Pacific. At Midway, SBDs damaged the IJN carriers Akagi, Kaga, Soryu and Hiryu, leading to loss of all four. 1/ TY @Sylvia70485099 ImageImageImageImage
2/ The SBD ("Scout Bomber Douglas") first flew in 1940. Recognition: circular perforated dive brakes; wings: compact, sturdy, non-folding. Crew: 2. 5,936 built, 1940–1944. Used by USA, France and New Zealand. Let’s visit the different versions and check out details… #Models ImageImageImageImage
3/ SBD-1: 1,000 hp Wright R-1820-32 Cyclone; 6-volt electrical system. 2 x .50 cal guns on upper cowling + 1 x .30 cal rear-facing on semi-circular mount. 57 built, all in 1940. USMC only. Images: aviation-history.com/douglas/sbd.ht…⬅️. ImageImageImage

Although future #warming will affect #vegetation, the big draw of this paper is the specific impact on #urban #forests. However, I would take quantitative estimates made with these #models with a grain of salt since they don't provide "true" urban climate signals. [1/n]
The study uses projections from 10 Global Climate Models (#GCMs) over 164 #cities; comparing modeled variables relevant to species survival against baseline values to predict future risk. A big issue is that most of these GCMs do not represent cities in any meaningful way. [2/n]
Several of the GCMs do not have explicit urban land cover or use simplified slab models. The former provides no urban-specific signals and the latter overestimates urban warming. More importantly, around half of the models use versions of the Community Land Model (CLM). [3/n]

1/ #ships #USNavy #models #WW2: Fletcher-class; 175 built 1942 to 1944. 2,500-tons full load. 376.5’ l x 39.5' w x 17.5' d, 60,000 shp, 2 × depth charge racks, 10 × 21” torpedo tubes; 6 × K-gun depth charge throwers. One rudder. ImageImageImageImage
2/ The Fletcher-class had (from slowest rate of fire and longest range to fastest rate of fire and shortest range) 5 × 5”/38, 5 × 40 mm, 7 × 20 mm. These provided three ranges of defense vs enemy aircraft. The 5” guns were dual-purpose to fire at shore targets, ships, etc. ImageImageImageImage
3/ First the 5"/38. These had 5" bores and were 38-calibers long (L/38). So total length was 5”x38=190”=15’ 10”! Range: 18,000-yards; 15 rpm (under ideal circumstances). These 4 show an unturreted 5"/38 and a twin 5"/38 on battleship Alabama. ImageImageImageImage

Avui hem parlat de #models #sistemes i #gransIdees de la #ciència al curs pel claustre de l'#EscoladelMar de #Vilassar. Fil perquè pot ser un recurs molón per altres escoles
Moltes de les coses que els he explicat venen arran de la recerca en didàctica de les ciències que es fa a l'@ICEUAB (em deixaria gent per això generalitzo). Tot això fa poc que ho he après gràcies a formar part d'un grup de treball com @EduglobalStem
Anem al tema:
“La competència científica és la capacitat que té un ciutadà reflexiu per involucrar-se en qüestions relacionades amb la ciència i amb les #idees de la ciència.” #PISA

#Fact: Clinicians, even those with expertise in stroke, perform poorly in predicting clinical outcomes
In this case-based study, overall accuracy for predicting death or disability at discharge was <20%😩

The @tesla #ModelS was released in 2012 and has an 8 year warranty on the battery. This means the market is about to start seeing an influx on second hand Tesla's with no battery warranty. Is this an issue?

cont...
@Tesla say that they'll guarantee the battery remains at 70% health during the warranty. For the 2012 model the range was 208 miles.

70% of that = 145 miles.

The oldest used Tesla Model S, currently for sale in the UK, is a 2014 car priced at £26k.

Cont..
Let's assume this has 80% battery health. That's just 166 miles per charge.

Not bad, you might say. They can charge quick etc. Except that this battery range will continue to drop as you own it. By Tesla's estimate, by 3.5% a year (8 years for 30% drop)

If millions fewer young people are doing twice-weekly #tests then obviously those numbers will go down.

And that children are no longer #mixing regularly will have significantly reduced #transmission amongst their own and other age groups, i.e. family members.

I'm not sure...
...this is 'news', though it's another failure of (public health) comms if folks are being left confused.

More concerning, however, is the implication the #models - which one assumes were those used to predict the effects of re-opening schools - either didn't or couldn't cope...
...with this entirely #predictable event, and that they will somehow not be able to handle winter #predictions even after young people go back to school in the autumn, and testing resumes 🤔

If 18 months into the pandemic, Government is still just 'driving by #dashboard' then...
