Chill Bangladesh Thread

Blippin should have taken the train instead
every 2 weeks , he would make a statement about how he was going to teach his enemies a lesson.
with this recent accident (who knows) IAF is now in first place , replacing BAF as the most incompetent air force in the region .

How do you know?

Maybe it was an inside job and the pilot jumped out of the heli at the last minute...

But seriously, I was astonished watching the last 30 seconds before the crash, which someone got on cellphone video, about 200 feet downhill.

The pilot went inside a blind cloud, fearing nothing. This is going one grade above incompetence, which is called reckless....

Do you drink lemon water in morning? My dad does. He believes it helps him keep his diabetes in check.

Please read the following excerpt from an Internet source:

Glycemic index and lemons

Glycemic index (GI) is an indication of how a food affects blood sugar levels. It’s measured on a scale from 0 to 100, with 100 being pure glucose. The higher the GI in a food, the larger the blood sugar spike.

Lemon juice, when consumed along with a food with a high GI, can slow the conversion of starch to sugar, thus lowering the food’s GI.

PhD Viva finally defended!

Ki je bhaal lagtese bhai!

I shall try to refrain from over celebration, as encouraged by our great prophet

Allhamdullilah!

Congrats. Which field ?

It was on Metallurgy and novel manufacturing processes (such as welding-based additive manufacturing)

China recently started making their own micro steel balls for their ball point pens (using TISCO product). Previously, these micro steel balls used to be imported from Japan.

Finally, China manufactures a ballpoint pen all by itself

That humble device you may well have lying around your desk has been the object of China's long and frustrating quest.

Maybe you can help China become more successful in achieving further independence from imported inputs using advanced alloys. Though I believe a large portion of advanced metallic alloy products are already domestically produced in China.

At some point you can also come back home and bring Chinese technology (CNC turning centers) to Bangladesh to train folks locally to help in making mass-produced labor-intensive auto-parts operations and forged parts production using simple sustainable processes.

3D Printing ? So how is welding involved here ? Maybe you know that the company Relativity Space is building entire rockets using 3D Printing in which it has managed to 3D Print the structures using proprietary alloys. Please watch this interview vid of the co-founder of Relativity as he takes the interviewer around his factory. Maybe you can leapfrog Bangladesh in this field using this simplifying, non-traditional technique. @Bilal9 bhai, which was the BD microprocessor implementation company you once mentioned ? Any space rocket will need computer control.

It's Wire-Arc-Additive Manufacturing. Basically using automated welding to cumulatively build layers on top of each other to create a part. Used in aerospace a lot. It has been around for quite some time

How is this different from metal 3D Printing which uses laser and powder spreading to build a part layer by layer ?

Sorry for the late reply

Laser-based additive manufacturing is usually powder-based. Instead of a wire-feed stock (as you get with most arc welding-based additive manufacturing), the material is deposited in powdered form

They have their advantages and disadvantages. Powder-based is more difficult from a health and safety perspective (need more elaborate factory setup as a result). Powdered metal is a very expensive and energy-consuming process vs wire. And also the deposition rate per energy input for laser welding is a lot lower than most arc welding. You use laser for some very high precision jobs. But arc-welding for larger components

Bhai that is the ultimate dream

I'd like to see Bangladesh become a knowledge-based high-tech economy one day. Bangladesh needs a lot more industry-to-academia collaboration. It's only being set up now (Dhaka university and Walton for instance), and it's very embryonic. Let's see where we are in 10 years' time.

I spent some time working in A*STAR SIMtech in Singapore, which is a government-run research institution designed to enrich Singapore Industry, which they have been tremendously successful at. Bear in mind, A*STAR was set up at a time Singapore barely produced any research papers. Even Lee Kuan Yew once said, "Singapore is a country of technicians, not scientists". But now they are among the leaders of Science & research In Asia. They made sure their primary, secondary (high school/college), and tertiary (university) educational institutions were up to par first, before then going onto the quaternary (post-doctoral/ industrial R&D I guess)

Bangladesh at the moment needs to improve its secondary education the most. Particularly pre-employment education, which is lacking. After then, perhaps we could build our own version of A*STAR and be a knowledge-based economy. I'm sure many Bangladeshi students dream of working in such an institution. They have the knack and determination for it. The question now is whether they have the institutional muscle to make it happen. Not yet, but let's see where we are in a few years time

Not possible, lol.
A 4 star Air Chief Martial managing a fleet size typically managed by a Colonel (=Group Captain) in the USAF is a world beating low.

BAF crashes more frequently per flying hour than IAF.

It is probably a South Asian thing to risk flying into the fog rather than abort which would cause "inconvenience" to the high ranking passengers and hurt the pilot's ego.
I can recall at least two incidents of our own - we almost killed the Kuwait Army Chief of Staff and his delegation in 2018 and lost Maj Gen Rafique and others in 2009.

This may have something to do with the colonial mindset of appeasing the boss no matter what.
In the US, the Secret Service can physically force the president to change movement paths or locations against his will if they deem fit.

Thanks for the info. If you watch the interview in this post above they are I think using arc welding to print the rocket's tankage and the metal feed coming as aluminium alloy wire. And they seem to be using regular powder-based printing for the engine block. The interview will be interesting for you.
