Abstract: The fully propagated real time-dependent density functional theory method have been applied to study the laser--molecule interaction in 5- and 6-benzyluracil (5BU and 6BU). Different parameters like direction‚ strength‚ wavelength of the laser field have been chosen in order to obtain the most efficient excitation of molecules. Results show that the 5BU and 6BU molecular systems have different responds to the applied laser field and different‚ well defined laser field parameters can be

In chapter 5‚ I learned that an adult human contains ten times as many foreign microbial cells as mammalian cells. I also learned a lot about host manipulation in animals from spiders to humans. I found it really intriguing that the cold virus actually triggers your sneezing reflex so that it can infect others around you. Other viruses‚ such as cholera and some STDs‚ also use various degrees of host manipulation to find transmission channels. I also found it interesting that our sense of disgust

In Ch 5 Paragraph 6-10‚ Atwood shows that through a feminist lens that woman in the book are shown as only useful for giving birth and household things only and shows that women are not needed for anything else besides that. They start of with women in the society. They separated women into different types of groups or roles. The roles were shown by the dress they were wearing; blue for wives‚ red for handmaids‚ and green for Marthas. This basically gets rid of women’s individuality.This may infer
