Math & Science ⇒ non-italic greek character

[itb1000]

Hi,
I am using \sigma in equations and in text.
\sigma has to be in bold, I use $\boldsymbol{\sigma}$, which works well. However, \sigma appears in bold and italic.
Is there a way to get \sigma bold and non-italic?
I tried with \mathrm ($\mathrm{\boldsymbol{\sigma}}$ but it still appears in italic.
Can somebody help me?
Thanks in advance,
Thierry

The upgreek package might be helpful.

Hi Thorsten,
I am using LaTeX2E and I do not find the upgreek package in the MiKTeX package manager.
Is there another package doing the same work?

We all are using LaTeX2e but maybe different LaTeX distributions. Following the link from my last reply you will find out that this package is part of the was bundle. This bundle should be listed in the MPM.

As an alternative you could use the kpfonts package. It is one of the few complete sets of fonts for text and math and it supports an option for upright Greek letters. The manual tells you more.
