On lots of electronic devices with replaceable batteries, the battery cover is secured by a screw.
I understand that it may be necessary to protect against child access to the battery bay, but using a screw necessitates the use of a screwdriver to open the battery cover, which can be inconvenient. It annoys me to no end that I need to open my toolbox, grab my screwdriver, and unscrew the darn thing to replace the batteries.
When is using a screw appropriate for securing a battery cover? Under what circumstances is a simple latch closure inadequate for a battery cover? Are there safety regulations that cover this?
It appears that there are legal requirements that specify that toys intended for young children must have secured battery covers. However, this question covers more than just toys, but pretty much any electronic device that has replaceable batteries. Aside from safety and regulatory requirements, when is it better to use a screw instead of a latch closure to secure the battery cover?
Also, what alternatives are there to a screwed-down battery cover that can prevent young children from accessing batteries while being more convenient than a screw closure?
Any such battery compartment must be “inaccessible” such that “it is not physically exposed by reason of a sealed casing and does not become exposed through reasonably foreseeable use and abuse of the product” (source). This may be very difficult to attain in a toolless manner, but any ideas are welcome.
Let $(M, omega)$ be a connected closed symplectic manifold of dimension $2n$.
Assume there exist smooth covering maps $phi_k:Mto M$ such that $phi_k^* omega=sqrt(n){k}omega$ for all $kgeq 1$. Is $n=1$ then?

Let $M$ be a closed connected complex manifold with $mathrm{dim}:M=n$. Can there exist holomorphic covering maps $phi_k:Mto M$ for all integers $kgeq 1$ such that $phi_k^*:H^n(M, mathbb{Z})to H^n(M, mathbb{Z})$ is multiplication by $k$?
Many apologies if this is totally standard! I couldn’t find it in the literature.
Background definitions:
A presheaf $X: textbf{Aff}^text{op} to textbf{Set}$ is an ind-scheme if it is a filtered colimit of schemes, where we regard a scheme as a presheaf via the Yoneda embedding (and then restrict to affine schemes), and the colimit is taken in the category $text{Psh}(textbf{Aff})$ of presheaves (i.e. the colimit is taken “pointwise”). One can impose the condition that all of the transition maps are closed immersions, and then call the result a strict ind-scheme.
Let’s say that $X$ is an ind-affine ind-scheme if it is a filtered colimit of affine schemes. (Side question: Is this the right terminology? It seems there are several distinct notions with this name in the literature.)
Context:
It is well known that a presheaf $X in text{Psh}(textbf{Aff})$ is represented by a scheme if and only if it satisfies the following two conditions: 1) $X$ is a Zariski sheaf and, 2) There is a covering of $X$ by open affine subfunctors.
Every ind-scheme is a Zariski sheaf (in fact satisfies the sheaf condition for the fpqc topology).
The affine Grassmannian (which is an ind-scheme) admits an open cover by ind-affine ind-schemes. See, e.g. the extremely helpful paper by Timo Richarz “Basics on Affine Grassmannians”.
Question:
Is there a similar characterization for (strict or otherwise) ind-schemes? I.e. is something like the following true: a presheaf $X$ is an ind-scheme if and only if 1) $X$ is a Zariski sheaf and, 2) $X$ admits a covering by open subfunctors which are ind-affine ind-schemes? Is it at least sufficient? If not, is there a name for the presheaves that satisfy this property?

First, look at this answer to the question "What is the difference between" Sign Up "," Sign In "and" Sign In "?
As Hellion describes those terms in general, I'm writing here in the context of the cyber world that also includes gadgets. you
I mentioned login and that's what makes me think you probably want
know the difference in the internet context.Well, registering simply means registering. Could be portal, newsletter
Or things like that. So when you visit and access anything to
first time, you must register. Often this is known as
Check in. For example, if you are new to Twitter, you must register
First.The interesting thing is to log in and log in. Well they both mean the same thing
You enter a place where you are already registered. The web portals
use both terms. Facebook, ELL and COCA call it Login, while
Google, Twitter, Bank of America and LinkedIn use Sign In.Please note that all of these portals use sign up for the first time process
register and do not register.
Basically you need a name for a page with "Check in"and"Log in"The two processes are different, so you can use one of the two names or you can use The term for the result or category of these actions, I like "Configurations","Bill","Profile","User","Member"
