The purpose of this chapter is to acquaint the reader with the chemical structures of various plant growth regulators and reports of their detection from plant sources. In general only plant growth substances from higher plants are considered. Growth sub
(0.5%, v/v) at 40 °C. The solution was heated and agitated constantly for 43200 s. Then the pH was adjusted to 5.6 with 1M NaOH. Subsequently, glycerol 1.6% was added as aplasticizer[26]. The solution was stirred overnight at room temperature. Finally, olive leaves and olive pomace...
The goal of this paper is to both understand and depathologize clinically significant mental distress related to criminalized contact with psychoactive biotic substances by employing a framework known as critical political ecology of health and disease f
Permeabilities of O2 and N2 were measured at 23°C for poly(vinyl alcohol)(PVA) membranes swollen to 30-80wt% with water or aqueous solutions of urea ((NH2)2CO), tetraethylammonium chloride ((C2H5)4NCl, TEACl) and sodium tetraphenylboride (NaB(C6H5)4, NaTPB). It was found that with...
Photocatalyst device comprises a light-guiding element and a photocatalytic substance arranged on the light-guiding element, where the photocatalytic substance comprises bismuth oxide, nitrogen-doped, carbon-doped or sulfur-doped titanium dioxide and/or a binary bismuth metal oxide compounds....
The mobile phases for gradient elution using the PhenylHexyl column consisted of 2 mM aqueous ammonium formate containing acetonitrile (1%, v/v) and formic acid (0.1%, v/v, pH 3, eluent A), as well as 2 mM ammonium formate solution with acetonitrile:methanol (1:1, v/v) containing...
Atmospheric organic aerosol (OA) are considered as a significant contributor to the light absorption of OA, but its relationship with abundance, composition and sources are not understood well. In this study, the abundance, chemical structural characteri

M Wyszkowski,A Ziolkowska 摘要: The aim of the present study was to determine the effect of soil contamination with petrol and diesel oil (2.5, 5, and 10 cm3 kg-1 soil) on the acidity and sorption capacity of the soil. In order to neutralize the impact of petroleum derivatives, ...
EPS can thus have a potential of interaction with various NPs and alter their bioavailability and toxicity, and it is necessary to iterate the potential role of EPS in the ecological impacts of NPs. Some researchers have studied the effect of EPS on nanotoxicity. It was found that in the ...
