Effect of more or less butter in pastry dough [baking]
Hi. if a dough has excess butter or too little; what changes ? Aiming for fine 'crumbly' result. My understanding of the word crumbly is like compacted flour dust, not compacted sand texture, breaking and collapsing when biten. Clues from the baking fans, please ?

Andrew Cuomo says companies should hire people with criminal record
Mister Cuomo can hire in his own businesses all the people with criminal records he wants. If that is also replacing/firing the ones with no criminal records, is his decision too. Just do not tell me who I should hire in my business.

Chemical that contaminates rivers...
Hello. Cannot remember the name of something that greatly affects rivers life from runoffs, if it was some insecticide or a fertilizer applied to soil in farms and its bad effects do not fade or decay with time. Was subject of many discussions ~10 years ago. If anyone can tell some names I may remember its. Something like permitine perhaps ? Thanks.

Why is scratching skin a highly 'rewarding' pleasure ?
Greetings. Animals do it too. From insects or skin conditions of whatever be the cause. Is there a benefit to the microorganisms on skin that cause the itching, as rising blood flow from scratching ? If it is a reaction to a chemical there is no microorganism to favor. Either from some skin condition cause or from an insect or contacting a plant; scratching produces a highly pleasant rewarding sensation. Can end damaging the skin from fingernails abrasiveness. Mosquitos, fleas... are bothersome if the 'bite' is felt but the later scratching is pleasant, no doubt.

Looking for very old posts; goofed again.
Once I found the way to look for my own old posts; now cannot find other than "my attachments" and got : Please guide me to the correct way for finding my old posts, not attachments. And if you know where to buy a new brain, also. Getting too old âšī¸

Have you ever seen this item ?
Or know what this gadget is for; or how does it work ? Am sorry, cannot make it a larger image âšī¸

Carbonates...
Hello all. chalk, gypsum, hydrated lime, magnesium carbonate, sodium carbonate, calcium sulfate, clay Seems there is a fine line differences in these minerals and their uses. Can anyone shine some simple light on their uses, properties ?

The use of white Portland cement as paint...
Good day. A lot of information available on the net; but seems the surfaces where it can be applied is missing details. What have you experienced or can comment/supply guidance ? Read the surfaces to apply can range from bare concrete block walls; bare brick; old deteriorated paint of several types as latex, colors that may bleed out, oil based, limewash... After nail holes are filled, preparing white Portland cement plus water and nothing else to the consistency of 'toothpaste' and applying with paint roller, brush, scraper?, to a smooth finish that will even and cover irregular lines. My specific case is 80 year old plaster walls with the corresponding scars and portions where painted layers have detached or turned dusty. (After wallpaper removed đ) What white Portland cement paste paint would not stick to ? (obviously clean) Recommended tools other than wide 'putty knives' for smooth finish application ? Or, mixing it with paint for better color blocking ? I understand 'primer' paint does not fill hairline cracks, white cement paste would be much different ? Can it be painted over after set ? Educate me, please.

Optimal location ?
Thanks, gentlemen. These use a single support post and the lower edge to soil : These show 2 extra sloped support elements as rafters under each 'column' of panels, as to not attach to the panel frame. The intention is to use the panel frames as rafters for single rows of panels, not as four+ high as in the left image. At the right side image, the optimal location of the single post by the person left knee is dependent of the length of the panel to be supported. Simple kits are : Where I see the sloped element being redundant to the panel frame, and the horizontal one, not needed. No underpurlin; instead the location of the post in function of a given panel length. This image below has front post, rear post and rafter under the underpurlins Trying to get rid of too many elements.

Optimal location ?
Hi. A 2 metre long solar panel has its frame supported with a post(s) into soil. The lower end is held anchored to flat soil. What is an optimal position "?" to get less convex bending or concave sagging ? Its ~20Kg weight distribution is very uniform, there is nothing more massive at any place.

Bronze and brass...
Great! Thanks. I have some diluted sulfuric acid for batteries; hoping will tell some clue, like presence of zinc in the alloy likely being brass.

Bronze and brass...
Hi. A drop of vinegar tells if magnesium or aluminium. Is there a simple way to tell if it is bronze or brass ?

Zeropole...
Thanks, studiot. Forget the ferrite. being plain iron; the field lines are also there. Yeeeeeah ! Did I 'invent' the zeropole concept ? Should it be more valuable than a monopole ? đ An iron magnet with no poles. Wow ! What would it be good for ?

Zeropole...
Hi. If all magnets and electromagnets form/have N and S poles, and field 'lines' go from one to the other. As I was told. An electromagnet rod core has the pole areas as : A ferrite or iron toroid, windings on it : Where are the magnetic poles located ? 𤨠Yes, direct current applied.

3D printing... For other than plastic ?
Any guidance to produce rubber parts with a tridimensional printer ? If gets too complex, perhaps some hard silicone instead ? Or room temperature vulcanizing RTV ? Would ultraviolet curing be ineludible ? What rubberish materials cure with UV ? Can 3D printers carve material out instead of pouring ? As to create a mold ? Is it just matter of putting a 'negative' image file to 'print' a mold ? Any capable hobby machine that you know of in the market ? As to start from a rubber block ? Yes, too many questions... tackle as many as you want.

Sodium-ion batteries...
Hi. The 'progress' is a couple of factories pedaling up manufacturing near silicon valley and another in China and Europe, from what I read. I do not know yet the consequences of catching fire in electric vehicles compared to lithium, and trying to extinguish with water...

Messages to the president...
Good morning mister president. Happy 100th day. We, the people, cannot fight nor reverse the caprices of your administration. Be aware you neither will be able to avoid the reversal of your actions by the next administration in four? years. It is the plowing-the-river situation. All the changes done now will affect -we the people- with no chance to return to 'normal' , leaving an irreversible wound. Whatever you do, do it properly without harming we the people. Am in the last days of my life, but my children deserve at least a decent life as I had. Do not spoil it as by then you and I will be under 6 feet where crying will not help restoring anything.

Any hands-on tinkerers here, or mostly theoretical scientists ?
Thank you. Been sporadically following if there was advances during the last ~10 years somewhere else since ojose.com and scirus.com went belly up. The simplistic first rotary drawing that cannot find now was very convincing of having a good potential; gadolinium exposed to magnetism, then moved to a place to dissipate the heat and later moved to a place without the magnetic field to absorb heat.

Any hands-on tinkerers here, or mostly theoretical scientists ?
Greetings. Has anyone here already; or what would it take to put together a rustic, magnetocaloric refrigerator using gadolinium, even if by manual cranking ? Gadolinium exposed to a magnetic field warms up; while In that state; does reversing the magnetic polarity changes anything, or removal of the field is needed ? Moving Gd into a magnetic field takes kinetic energy ? Removing it from a magnetic field also uses kinetic energy ?
