kaishi nitrogen determination method to obtain a false high protein content.
Melamine contains up to 66.6% nitrogen and is white and tasteless. It is an ideal protein impersonate without a simple method. It is estimated that the testing protein content will be increased by one percentage point in plant protein powder and feed, with melamine spending only 1/5 of the actual protein raw material.

Originally, today I plan to write an instance tutorial to briefly introduce how easy it is to use this ultra-Lightweight Framework for Development. However, some small bugs are found during use.
As a result, today I am excited about modifying N multi-code, extracting SQL components into a separate c

There are too many materials for database operations and you are familiar with them.However, sometimes the data volume is small, but frequently updated variable operations usually use a custom structure, but the maintainability and flexibility of the custom structure is not as good as that of the temporary table, we can use datatable as a temporary memory table to flexibly add columns and rows as database operations to comple

I have been using js for a long time, but I have never gotten into the js array form. Occasionally, it is a simple string. split (char ). During this period of time, there were a lot of projects that used arrays. I thought I could not help myself as a js master! Haha. After learning it, I learned that the js array is far more powerful than VB and C #. Let's take a look.
