More information on Rollerball and Ballpoint pens


by team UAB

Since the question came up after Elise's presentation and I was curious, I thought I would find out what was unique to the different pen types. The basic difference comes down to the ink. This link is to a Wikipedia article. I reviewed a number of sites, but this one had more complete information about the differences of rollerball and the advantages versus disadvantages. I will also include some other links below for your interest.

I thought this was interesting. I knew there was that much science in something so small that we use every day. You learn something new ever day.

AD and CG - it's true. forensics can pop up anywhere. for any item that leaves behind something, you just have to ask, is there any way that this can be matched to something in the depositing device (i.e. pen)? Then ask, how many other devices could also leave this behind (i.e. many pens have the same type of ink)?

[b]Description[/b]

Generic Viagra (sildenafil citrate; brand names include: Aphrodil / Edegra / Erasmo / Penegra / Revatio / Supra / Zwagra) is an effective treatment for erectile dysfunction regardless of the cause or duration of the problem or the age of the patient.
Sildenafil Citrate is the active ingredient used to treat erectile dysfunction (impotence) in men. It can help men who have erectile dysfunction get and sustain an erection when they are sexually excited.
Generic Viagra is manufactured in accordance with World Health Organization standards and guidelines (WHO-GMP). Also you can find on our sites.
Generic Viagra is made with thorough reverse engineering for the sildenafil citrate molecule - a totally different process of making sildenafil and its reaction. That is why it takes effect in 15 minutes compared to other drugs which take 30-40 minutes to take effect.

Even in the most sexually liberated and self-satisfied of nations, many people still yearn to burn more, to feel ready for bedding no matter what the clock says and to desire their partner of 23 years as much as they did when their love was brand new.
The market is saturated with books on how to revive a flagging libido or spice up monotonous sex, and sex therapists say “lack of desire” is one of the most common complaints they hear from patients, particularly women.
