    Sammanfattning : När en atom absorberar fotoner, i växelverkan med tillräckligt högenergetisktljus, så kan en (eller flera) av atomens elektroner ”sparkas ut”. Det resulterar i en positivt laddad jon och en (eller flera) så kallade fotoelektroner. Den här processen är känd som den fotoelektriska effekten, men kallas också för fotojonisering. LÄS MER

    Sammanfattning : Before 1990 environmental reporting in Sweden was a marginal and unsystematic activity undertaken by a small number of large companies in high-profile industries. The 1990's have witnessed a dramatic increase in environmental reporting practice, and today a large number of companies in almost all industries annually report considerable amounts of environmental information.

    Sammanfattning : In order to interfere pharmacologically with tumor growth and metastasis, it is of great importance to understand the status of the signal transduction systems in tumor cells. The effect of various oncogenes on cellular signal transduction events has largely been studied in short term experiments. LÄS MER
