Isolation of an acidic protein from rat brain.
In aqueous extracts of rat brain, spinal cord, and sciatic nerve, a protein antigen has been detected which could not be shown in similarly prepared extracts of a variety of other rat tissues. The protein, designated antigen (Y, had a high mobility in zone electrophoresis at pH 7.4. Antigen cr was isolated and was found to consist of a single type of subunit having a molecular weight of about 3...
متن کاملMicrobial ecology of an extreme acidic environment, the Tinto River.
The Tinto River (Huelva, southwestern Spain) is an extreme environment with a rather constant acidic pH along the entire river and a high concentration of heavy metals. The extreme conditions of the Tinto ecosystem are generated by the metabolic activity of chemolithotrophic microorganisms thriving in the rich complex sulfides of the Iberian Pyrite Belt. Molecular ecology techniques were used t...
متن کاملthe aesthetic dimension of howard barkers art: a frankfurtian approach to scenes from an execution and no end of blame
رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
Aquatic Organisms in Acidic Environments: A Literata[
_ _ Acid deposition has aroused concern about aquatic organisms in soft water lakes and streams, as the loss of indigenous species is commonly observed when pH decreases. This literature review was initiated to intensively examine the distribution of invertebrates with respect to pH, in order to define the tolerance limits of various species in acidified waters and predict how acidification wou...
متن کاملPyrite dissolution in acidic media
Oxidation of pyrite in aqueous solutions in contact with air (oxygen 20%) was studied at 25°C using short-term batch experiments. Fe and SO4 2 were the only dissolved Fe and S species detected in these solutions. After a short period, R [S]tot/[Fe]tot stabilized from 1.25 at pH 1.5 to 1.6 at pH 3. These R values were found to be consistent with previously published measurements (as calculated f...
