Interacting Blends of Novel Acrylated Poly(Ester-Amide) Resins - I with Methyl Methacrylate Monomer—Part 1
Bisphthalamic acids were prepared by reaction of phthalic anhydride and aliphatic diamines. Novel poly(ester-amide)s (PEAs) were prepared by reaction of epoxy resin with bisphthalamic acids. Acrylation of PEAs were carried out using acryloyl chloride; products are called acrylated poly(ester-amide)s (APEAs). Elemental analysis, Number average molecular weight and IR spectra recorded for both PEAs and APEAs. Blending of APEAs was carried out with methyl methacrylate monomer. Curing of APEAs-MMA blends were monitored on differential scanning calorimeter. Composites of these blends have been laminated and characterized. Unreinforced cured samples of these blends were analyzed thermogravimetrically.

Introduction and experience with the primary mail services based on their names for students
Kyushu University provided mail service based on student IDs such as "1AB10123X" to the university students for many years. Using this model, we had problems communicating with the students who graduated from the University and enrolled in the graduate school. The students received new mail addresses based on their new student IDs such as "2AB12789Y". Faculty members were forced to change the student mail addresses in the mailing lists and in their mail client address book. Furthermore, students were forced to notify the e-mail address change to all of their existing contacts. We introduced a new mail system to provide addresses based on the student name, as well as student ID in April 2011. The new naming convention uses the following format: lastname.firstname.999 where 999 is a random number of 3 digits. Students can select some combination patterns of their first and last names for Japanese. We also consider the middle names for foreign students. In the system implementation, we did not have the formal information of alphabetical names for students. We generated alphabetical names from Japanese Katakana names. It is not easy for us to get the appropriate name in this manner. We implemented a confirmation stage of the alphabetical name at first use, and then students can select their mail addresses for their convenience. We paid much attention to the user interface in the system. Since April 2011, the number of users who use the mail address based on their own name has been increasing gradually. This paper will detail the usage status of the new system.
