Structure of the education system in China

Secondary education

The Chinese educational system is highly competitive and there is ample evidence throughout the different stages of the system. However the levels of school failure are very low and the literacy rate exceeds 94 percent, according to World Bank data. A continuation explain the structure around several basic levels:

Primary Education:

Primary education usually begins at six years old and is mandatory. Usually last six years. During the period of compulsory education, teaching guidelines contemplate attention to both purely academic issues as moral and labor.

Secondary education:

Secondary education, divided in turn into junior secondary education and secondary education in the second cycle. The first cycle usually lasts 3 years and is mandatory (the Chinese authorities have established a total of nine years of compulsory education). To enter upper secondary education, we must overcome the relevant exams training. The upper secondary education also lasts, usually three years.

Professional education: 

since 1996, the Vocational Education Act was enacted, have laid the foundation for a well-structured professional education. Within it several levels differ.

Higher Education: 

within higher education, which is taught in universities, colleges and vocational training centers, we must distinguish vocational training, higher education and postgraduate courses (Masters and PhD).
The academic year is structured around two semesters of about 20 weeks each. The first begins in September and the second in February. Class attendance is mandatory.

The Process Of Sublimation

the proses of sublimation

Sublimation is the movement of a body from solid to gaseous state without passing through the liquid state. This transformation takes place with the purchase of heat and is therefore an endothermic process.
The sublimation occurs in those substances in which the vapor pressure equals the value of atmospheric pressure before reaching the melting temperature.

The solids that sublime (all are molecular solids with low binding energy), can also merge provided during the heating of their vapor pressure is maintained consistently higher than the pressure of sublimation: iodine so heated in a closed container melts at 113.7 ° C (temperature at which the saturated vapor pressure of the iodine that is about 90 mmHg).

The process of bublimazione and subsequent condensation of the vapor, similar to the distillation of liquids, is often used for separating a species that sublimates from other species that do not sublimate.
The phenomenon of the sublimation of solids is matched to that of the evaporation of liquids; in both cases, in fact, surface molecules of a condensed phase change to the state of steam.

But while in the evaporation of the liquid may form steam even within the liquid mass (boiling phenomenon), the similar phenomenon does not occur in the sublimation. This is due to the fact that in liquids the molecules are mobile and assogettate to convection and the heat supplied from the outside is rapidly distributed among all the molecules constituting the liquid mass. In solids instead of the surface molecules that absorb heat will transmit only a small portion within the solid, and, if the bonds between the molecules of the solid are weak, they may be found to have sufficient energy to pass directly from the solid state to the state of steam: in sublimation, and then, the steam is generated only at the surface, and not within the solid.

Examples of substances that can sublimate: iodine, naphthalene, camphor, solid carbon dioxide (also known as dry ice).

Single Cell Organisms


Protozoa are organisms that consist of only one cell. They are compared with the multicellular organisms or metazoans. The division into single and multi-Zeller is purely descriptive and gives no information on degree of relationship, lifestyle or internal structure and metabolic processes.

Protozoa therefore not form a closed kinship group. Single-celled animals include all archaea, most Bacteria, fungi and some protists many. They vary in size from less than a 1 micron (z. B.
Nanoarchaeum equitans) and several centimeters (z. B. Acetabularia). Some protozoa can form cell colonies.

The first single-celled organisms were discovered in 1674 by Antoni van Leeuwenhoek. [1] According to older views all eukaryotes were divided only into the two kingdoms of plants and animals, which were accordingly unicellular plants and animals. For example, the amoebae were counted as single-celled animals, some of their representatives to the slime molds and flagellate Euglena flagellates as alternately to the unicellular algae and unicellular animals.

What Is Chemical Engineering?

chemical engineering

Chemical Engineering is a discipline historically developed for the chemical industry. This specialization ensures the implementation of the material transformation processes (physical or chemical).

These processing operations are common to other sectors, its field has naturally expanded energy, aerospace, cosmetics, food, water treatment...

This evolving discipline was then renamed "Chemical Engineering - Process Engineering" and it combines subjects like chemistry, fluid mechanics, thermal, automation ... General diagram of a process.

green Chemistry
The chemical industry increasingly limit the impact of its activities on the environment
Its action is to anticipate the European environmental guidelines and government that impose strong constraints (discharge standards more stringent). This necessarily requires the development of new processes or environmentally

The hCG-GP technician works in all sectors and not just heavy chemicals or petrochemicals. Eg automotive, aerospace, environment, bio-technology, renewable energy, cosmetics, pharmaceutical, food.

Study Visa For Mexico City


It importation apply for a visa well in advance of compensate

your course. Many students do not realize how long it takes the process and do not do it enough. Your request may include the following:

Have vaccines or if you come from an area at high risk of tuberculosis, a chest radiograph
Documents showing your finances and certifications
Attend an interview or a biometric test
Awake an English test.
You can apply for a visa up to 3 months before the start of your course, but it's good to start your research and you need to plan ahead.

Child Visitor Visa: You can apply if you are 17 or younger and want to study in the UK for up to six months (or 12 months if you are accompanying an academic visitor).
Student Visitor Visa: You can apply if you are 18 or older and want to study in the UK for up to six months. If you want to study only English courses, you can request an extended student visitor visa to stay for up to 11 months.
The next two visas allow you to do a longer course in the UK.

Tier 4 (Child) student visa: You can apply if you are between 4 and 17 years old. If you are between 4 and 15 years of age, you must attend an independent, tuition in the UK school.
Tier 4 (General) Student Visa: You can apply if you want to come to the UK to continue your studies after 16 years.
