An Experiment of NO (nitrogen monoxide) Adsorption by a Soil Filter

Pesticide Adsorption and Leaching in Soil: An ELISA Laboratory Experiment

Inexpensive pesticide measurement by Enzyme-Linked lmmunoSorbent Assay (ELISA) technology, widely used for environmental monitoring, may be a useful tool for providing instruction on the environmental f te of pesticides in the classroom. A laboratory experiment hat provides instruction in state-of-the-art ELISA pesticide testing methods and demonstrates the effect of soil organic matter content...

the 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...

Nitrogen and Hydrogen Adsorption by an Organic Microporous Crystal**

Quick on the uptake: Following its identification during a targeted search, the intriguing crystal structure of 3,3',4,4'-tetra(trimethylsilylethynyl)biphenyl was investigated. Simple removal of the included solvent provides an organic crystal with an open microporous structure that has a striking similarity to that of zeolite A (see picture). Reversible adsorption of nitrogen and hydrogen gase...

Fluometuron Adsorption to Soil Influenced by Best Management Practices (BMPs) Established Filter Strip and Riparian Zones

Nitrogen and carbon dioxide adsorption by soils.

High-resolution nitrogen (77 K) and carbon dioxide (273 K) adsorption at subatmospheric pressures has been studied for a range of model soils of various origins with different organic matter (OM) contents. It is demonstrated that N2 and CO2 molecules probe different regions of soil particles. Nitrogen is adsorbed primarily on the outer surface of soil particles, while CO2 has a higher affinity ...
