吃得太咸，会伤肾吗？

食物中95%的盐分通过肾脏代谢，高盐饮食可能带来钠潴留和高血压，导致肾小球处于三高”（高压力、高灌注和高滤过）状态，加重肾脏负担。

《中国居民膳食指南》建议每日食盐摄入量应小于5g(约为一啤酒瓶盖的量)，成年人每日需饮水1500至1700毫升，保证尿量，减少肾脏负担。可尝试中医固本培元方剂，桑葚补肾固精，黑枸杞益肾滋补，覆盆子强肾润燥，三者配伍，补肾养心。

PS：现在在外面吃的快餐，往往重油重盐，虽说自己在家煮饭会健康一些，但有些人工作太忙没时间煮饭。因此，可以通过多喝水来减少肾脏负担。由于现在很多人往往不重视喝水，专注于电子产品，以至于忘记喝水，长期以往加上高盐饮食，身体就会出问题。

Base change map $U\times_{X}X\rightarrow U\times_{Y}Y$

My question: Let $X,Y$ be schemes. Let $X\rightarrow Y,X\rightarrow X, Y\rightarrow Y$ be morphisms of schemes. Why the morphism $U\times_{X}X\rightarrow U\times_{Y}Y$ is the base change of $X\rightarrow X\times_{Y}Y$ by $U\times_{Y}Y\rightarrow Y$?Here is the diagram I try, where the triangle is commutative. But I found that $(U\times_{Y}Y)\times_{Y}(X\times_{Y}Y)=U\times_{Y}X\times_{Y}Y=U\times_{Y}X$, i.e. I can not obtain the desired $U\times_{X}X$. What mistakes do I make?Here is the context ...

Power series expansion for sine function is Cauchy?

Consider the power series expansion of sine function $$S=(\sum_{i=0}^{j}\frac{(-1)^{i}}{(2i+1)!}r^{2i+1})_{i\in\mathbb{N}}, 0\leq r\leq2\pi.$$ Then is the series $S$ a Cauchy sequence?Let $\varepsilon>0$. Is it possible to find the very integer $N>0$ such that for any $m,n\geq N$$$\left|\sum_{j=n}^{m}\frac{(-1)^{j}}{(2j+1)!}r^{2j+1}\right|\leq\sum_{j=n}^{m}\frac{1}{(2j+1)!}r^{2j+1}<\varepsilon ?$$Proof 1. It is well-known that the power series expansion of $\sin x$ is convergent everywh ...

When is a scheme over an affine scheme affine?

Question: Let $X$ be a scheme. Let ${\rm{Spec}}(R)$ be an affine scheme for some ring $R$. Suppose that there is a morphism of schemes $f:X\rightarrow{\rm{Spec}}(R)$. What properties should $f$ have so that $X$ is also an affine scheme? Or what conditions can make $X$ affine?Answer: If $f$ is an affine morphism, then $X$ is affine by definition.This is an "if and only if". If $X$ is affine, the so is $f$. See theorem 7.3.7 in Vakil's Foundations of Algebraic Geometry, or 29.11.3 and 29.11.4 in t ...

Archimedean property written multiplicatively

My question: Let $(\Gamma,+,\leq)$ be an ordered abelian group. We know that archimedean property can be stated as: for all $a,b\in\Gamma$ with $a>0,b\geq0$, there exists $n\geq0$ such that $b\leq na$. However, if we consider the multiplicative case, namely $(\Gamma,\cdot,\leq)$ is the ordered abelian group. Is there exists Archimedean property written multiplicatively? I think there is. And I state that as follows: for all $a,b\in\Gamma$ with $b<1,a\leq1$, there exists $n\geq0$ such that ...

Is fully faithful functor between groupoids injective on objects?

My question: Let $\cal{C}$ and $\cal{D}$ be two groupoids, i.e. the category whose morphisms are isomorphisms. Let $F:\cal{C}\rightarrow\cal{D}$ be a fully faithful functor from $\cal{C}$ to $\cal{D}$. Then is $F$ injective on objects? In other words, is the object function $F:{\rm{Ob}}(\cal{C})\rightarrow{\rm{Ob}}(\cal{D})$ injective?Answer: No. Given any set $X$ we can construct a groupoid called the indiscrete groupoid on $X$, which has a unique (iso)morphism $x \to y$ for $x, y \in X$. Every ...

What do the local sections of an nilpotent ideal sheaf look like?

Question: Let $(X, O_X)$ be a scheme. and $I$ an nilptoent ideal sheaf. i.e. $I^n=0$ for some $n$. Would this imply that each $I(U)$ is an nilpotent ideal of $O_X(U)$?Answer: Let $I\subseteq \mathcal{O}_X$ be an ideal sheaf, and let $\mathcal{F}$ be the presheaf assigning to each open subset $U$ of $X$ the ideal $I(U)^n\subseteq \mathcal{O}_X(U)$. You say that $I$ is nilpotent of degree $n$ if $\mathcal{F}^\#$ is zero, where $\#$ is used to denote sheafification. But, since $\mathcal{F}$ is a se ...

A finite field extension of $\mathbb{R}$ is either $\mathbb{R}$ or isomorphic to $\mathbb{C}$

We need to prove the following proposition:Let $F$ be a field containing $\mathbb{R}$ with the property that $\dim_{\mathbb R}F < \infty$. Then either $F \cong \mathbb R$ or $F \cong \mathbb C$.We give three proof in the following, where the first one is the most simple, and the last one is the most complicated.Proof 1. By the uniqueness of the algebraic closure, we have an embedding $F \hookrightarrow \mathbb C$, hence we have $\mathbb R \subset F \subset \mathbb C$. The result follows from ...

Some thought of p-divisible groups and p-adic Hodge theory

The name "p-divisible group" is somewhat misleading, which in fact has another name "Barsotti-Tate group". A p-divisible group is not merely just a kind of group. lt is more general. In fact, a p-divisible group can be viewed as a tower of affine group schemes with some extra conditions. Historically, p-divisible groups were the main stimulus for p-adic Hodge theory. So l think that studying p-divisible groups is the key to study p-adic Hodge theory.However, today's p-adic Hodge theory is much m ...

Differences between collection, class, set, and family

A collection shall consists of mathematical objects that may not share some unambiguously properties. This is different from the so-called class, which consists of mathematical objects that share unambiguously properties. However, a class may not form a set. And we call such classes proper classes. What's more, a family is different from a class. A indexed family or simply family is a collection of mathematical objects that is indexed by a set called index set.--------------------This paragraph ...

One should do mathematics for the sake of oneself

Well, yesterday, when l was typing my articles excitedly, the boring class was over, so l had to stop this inspiring moment. What l wanna say at last is that one should really do mathematics for the sake of satisfying one's curiosity, You do mathematics maybe just to understand some kind of concepts. Our purpose of doing mathematics is not to have some specific problems solved, on the contrary, unsolved problems are the vitality of mathematics. Well, recently, l have written my essay named facto ...
