Ciência e Natura: Announcements <p style="text-align: justify;">The <strong>Ciência e Natura</strong> Journal was created in 1979 to meet the needs of researchers from the different areas of the Exact and Natural Sciences Center (CCNE), to publish their work, to disclose them and to maintain interchange with other publications.</p> en-US Sun, 19 Dec 2021 15:09:13 -0300 OJS 60 Ciência e Natura on a new system version <p>The Ciência e Natura is an institutional journal that integrates the Portal de Periódicos of the UFSM and is already operating with the new version. This change will provide a more pleasant experience for all available profiles.</p> <p><br />We inform that we are implementing new features in the system. If you see something that could be improved or corrected, get in touch with us, and contribute so that we can collectively improve the journal's website.</p> <p><br />We appreciate your understanding for the time the system was down and for your interest in publishing in the journal.

Three preservatives were evaluated, one of them unpublished, using a simple, low-cost and effective analysis technique. All preservatives were shown to be very phytotoxic even at high dilutions in relation to the concentrations usually used in bamboo, compromising both germination and root development. Thus, the disposal without treatment in the soil will cause risks to the vegetation. Thu, 17 Jun 2021 09:17:44 -0300 Highlights: V. 43, Special Edition, UFV <p>1. There was an increase in the motivation for change of the participants after a ketamine single administration.</p><p>2. There was a reduction on GSI of psychiatric symptoms in the moments before and after ketamine administration. <br />3.
