identification of organic compounds. Among them, NMR (1HNMR) is the most widely used structural analysis method, it is mainly based on the spectra of each peak group of chemical displacement, peak strength, peak group number and peak-splitting conditions to infer the corresponding structural units. ChemDraw the process of predicting the chemical shift of NMR is as follows:1. First check the chemical structure of propranolol (e.g.).Propranolol structu

1. PrefaceA lot of knowledge about UML, the deep grasp of some software modeling ideas, need a certain accumulation of practice.before summing up the study of the design pattern , it is necessary to understand the design of the class diagram so that it is easy to understand the static structure diagram of the design pattern. 2. Class Diagram overviewWhat is a class diagram? It describes a diagram that shows a set of classes, interfaces, collaborations, and relationships between them.What are the

What is the modified Poplar film faced plywood? This film faced plywood is the new style concrete formwork panel which have the superiority like smooth surface, large format, light weight, H IgH strength, high resistance and can reduce the advantages of both plastering, high turnover frequency etc. In addition, this plywood is a kind of the Eco friendly filmfaced plywood.So the high strength modified Poplar Corefilm faced formwork plywoodIs a relatively successful product. Accordingly theH20 Wo

The main differences are seven points:1, the composition of the material is different: lithium batteries with carbon materials (graphite) as the cathode, lithium-containing compounds as the positive electrode, nickel-cadmium battery cathode from the nickel oxide powder and graphite powder and other active substances, the anode is composed of cadmium oxide powder and the active substance of iron oxide powder. 2, the working principle is different: the

Glycyrrhizic acid (or Glycyrrhizic acid or Glycyrrhizic acid ) is the main sweet ingredient of Licorice ( licorice ) root. Structurally, it is a saponin and has been used as a emusifier in food and cosmetics and gel forming agents. its glycoside ligand is licorice acid , which has thus been used as a precursor to compounds, for example, it is used in Japan to prevent cancer in chronic liver disease in patients with hepatitis C .

A large number of smoking, blood hbco (carbon and oxygen hemoglobin) increased, patients HGB will be significantly increased.2. Hyperlipidemia can make hgb false increase.3. Vigorous and long-term physical exercise can be reduced.4. Intravenous input of amino acids affects the accuracy of HB assay, resulting in false increas

Problem Description:An organic compound are any member of a large class of chemical compounds whose molecules contain carbon. Themolar mass of an organic compound are the mass of one mole of the organic compound. The molar mass of an organic compound can is computed from the standard atomic weights of the elements.Organic compound is given as a molecular formula, Dr. Chon wants to find its molar mass. A molecular formula, such asC3H4O3, identifies eac

look can see the capillaries under the skin, and the acid has a high sensitivity, will be exposed to the sun is particularly easy to tan, Pigmentation and other symptoms intensified. More serious is the fluorescent agent, lead mercury compounds and other heavy metals are often used by unscrupulous manufacturers for whitening freckle Mask, the use of skin may temporarily become white, but the skin is seriously fibrous, sensitive peeling afraid of ligh

This article is a detailed analysis of the interpreter pattern in PHP design mode, which requires a friend's reference Interpreter (interpreter) mode, which consists of a grammar representation with a hierarchical hierarchy of compounds, rules are mapped to classes, and expressions following the grammar can be converted into an abstract syntax tree, with no content other than the instance object graph of the composite pattern.

bacteria on different human skin are different, and the composition of sweat is also different, this leads to a difference in their attractiveness to mosquitoes. Some human sweat also contains mosquito-annoying ingredients, such as aldehyde, xinaldehyde, nonaldehyde and some ketone which are natural mosquito repellent agents. In particular, when the two ketone compounds in sweat are mixed in a ratio, the mosquito repellent effect even exceeds the DEE

, with the extension of time, the aroma of the tea will change from high to low, and the fragrance will be changed from the fragrance of the new tea to low turbidity. Third, you can also distinguish between the new tea and the Chen tea from the taste of the tea. During the storage process, the tea leaves contain phenolic compounds, amino acids, vitamins, and other components that constitute a taste. Some are decomposed and volatile, and some are redu

The shocking plot behind Japanese Nippon Paint !!Do not forget 918, start from me and resist Japanese goodsNippon Paint is Japanese lacquer, a Japanese military enterprise!The word "Li bang" is the transliteration of Nippon, Which is Japan"Nippon Paint" is "Japanese paint ". Japanese military enterprises sell their products to China as "Nippon". There are two meanings: first, they conceal the true meaning of their product names and cheat the Chinese people. Second, the concept of "Creating a s

Following opium and morphine, a more dangerous drug has come to the human world, and it is heroin. Heroin is a semi-synthetic opium drug and has a history of more than one hundred years. The pure heroin (commonly known as the white powder) mainly comes from the Golden Triangle (borders of Myanmar, Thailand, and Cambodia), some from Lebanon and Syria, and more from Pakistan. The color, precision, and purity of the product depend on the origin. White from Thailand, both pure and white from Leban

interfaces is simply for the strategy model of the birth. The difference between comparable and comparator in the article, detailed the use of comparator. For example, there is a sort method in collections, because the elements inside the collection are likely to be compound objects, and the composite objects are not like the basic data types, and can be sorted by size, how are the compounds sorted? Therefore, Java requires that if the defined compou
