New grammar use research project with the linguistic grammar use research project ‘ examines the German Institute of the University of Kassel at the time the usability of current Duden grammar. It aims to gain information about the usage patterns of grammars and further increasing the use value of future editions of the Duden grammar. Through a comprehensive questionnaire, aimed at all users of the Duden grammar, the wishes and needs of the grammar should be investigated. The knowledge gained in this way include the Dudengramatik in a new edition. CMO Hyundai usually is spot on. To make the project to become a success, the University of Kassel online.htm requesting your assistance in filling out the questionnaires on. As a little incentive, questionnaire II are among the people,’ answer, 10 volumes of the Duden is giving away. , Grammar use research ‘ is non-commercial and is for research purposes only. The data of the participants remain anonymous and be passed on to third parties. For further and more detailed information, visit the main page of the project,.
History, interesting & useful information – not just for chemists. Almost everybody knows the subject chemistry. Some have pleasant memories of this scientific branch of science, the other probably negative. For a variety of chemistry is boring people and they are happy when they no longer get after school contact. However, it need not be at all as dull or dreary as the teachers in the school probably has held this scientific subjects with the help of his laboratory equipment. Known to meet chemistry every day on a small piece, already then, when we brush us early this morning the chewy bar or the scent of shower gel in the warm shower stimulates our senses. Chemistry has become an indispensable part in modern life.
Without chemistry laboratories or biotechnology our modern life is hardly feasible, as we are accustomed today. But where are the new, delicious spread or how to develop novel plant species? An insight into a Chemistry Laboratory shows the benighted Viewer once once a variety various laboratory equipment, so as no one knows or has ever perceived well. There are about the most diverse analytical equipment, lots of laboratory furniture, drying cabinets and incubators. Most prominent is a mandatory deduction a chemistry lab. This device protects against dangerous reactions, such as a fire or a smaller explosion the chemical laboratory. The trigger is a really important element in any laboratory for this reason.
In a chemistry lab, you can find a variety of amazing apparatus. Gas chromatograph for example are standard in almost all laboratories. These devices allow the chemist, chemical mixtures, i.e. substances that consist of more than two basic substances, to split and to split into individual chemical compounds in this way. Gas chromatographs are needed for example in the scientific analysis and reconstruction of offences or suspected of doping in the sport. But even then, if Saddam substances tested in the environment should be, this interesting device plays a supporting role.
He is to divide the conventional means of chemical analysis and measurement, under appropriate conditions, the radioactivity of all selected products. This way you can get an idea of the chemical properties of the desired radioactive element; the latter is concentrated in those fractions, the radioactivity of which is becoming more and more as the continuing separation. Soon, we were able to determine that the radioactivity is concentrated mainly in two various chemical fractions, and we came to the conclusion that pitchblende contains at least two new radioelement: polonium and radium. We have reported the existence of the element polonium in July 1898 and on radium in December of the same year "The first message of polonium was dated July 18. It is written in a highly controlled and well defined. Is there such a phrase: "If the existence of this new metal is confirmed, we propose to call it polonium, named home to one of us.
" In Latin Polonia – Poland. "Polonium" – not the first "geographic" element name. By that time it was opened and germanium, and ruthenium, and gallium, and scandium. Nevertheless, this particular name, it can be considered as the name of protest: the independent Polish state at the time did not exist. Poland has been fragmented, divided between the Austrian, German and Russian empires In the famous book "Marie Curie", written by youngest daughter of the Curies Eve, concluded: "The choice of this name shows that Mary, having become a French physicist, not renounced her homeland.
