Prediction of single particle settling velocities through liquid fluidized beds
(Powder Technology, 2009)
Single particle settling velocities through water fluidized beds of mono-sized glass spheres (dp = 0.645, 1.20, 1.94, 2.98 and 5 mm in diameter) were studied experimentally using a column, 40 mm in diameter. The settling ...
Diagnostic of silicon piezoresistive pressure sensors by low frequency noise measurements
(Sensors and Actuators, A: Physical, 2008)
Low frequency noise measurements can be used as a tool in diagnostics of silicon diaphragm-based piezoresistive pressure sensors after the sensor encapsulation and oil filling process are finished. We measured noise in ...
Experimentally observable transitions between dynamical states in complex reaction systems
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Identification of trends and their correspondence with dynamical state transitions are briefly discussed oil several reaction network models. The influence of different threshold values oil the trend analysis and dynamical ...
The molecular properties of nitrobenzanthrone isomers and their mutagenic activities
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
The mutagenic activity of five mono-substituted nitrobenzanthrones (NBA) has been determined in the Ames assay (Takamura-Enya et al., 2006). In the present study, a theoretical investigation of the electronic properties ...
Antiglioma action of xanthones from Gentiana kochiana: Mechanistic and structure-activity requirements
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The present study identifies xanthones gentiakochianin and gentiacaulein as the active principles responsible for the in vitro antiglioma action of ether and methanolic extracts of the plant Gentiana kochiana. Gentiakochianin ...
Application of non-thermal plasma reactor and Fenton reaction for degradation of ibuprofen
(Elsevier, 2015)
Pharmaceutical compounds have been detected frequently in surface and ground water. Advanced Oxidation Processes (AOPs) were reported as very efficient for removal of various organic compounds. Nevertheless, due to incomplete ...
Structural differences in diarylheptanoids analogues from Alnus viridis and Alnus glutinosa influence their activity and selectivity towards cancer cells
(Elsevier, 2016)
Diarylheptanoids represent a group of plant secondary metabolites that possess multiple biological properties and are increasingly recognized for their therapeutic potential. A comparative study was performed on structurally ...
Corrosion influence on surface appearance and microstructure of compo cast ZA27/SiCp composites in sodium chloride solution
(Elsevier, 2016)
The influence of corrosion on the surface appearance and microstructure of particulate ZA27/SiCp composites was examined after 30 d immersion in a sodium chloride solution with the access of atmospheric oxygen. The composites ...
Parallel alignment of water and aryl rings-crystallographic and theoretical evidence for the interaction
(Royal Soc Chemistry, Cambridge, 2008)
Analysis of crystal structures from the Cambridge Structural Database (CSD) that involve close contact between water and aryl rings revealed the existance of conformations where the water molecule or one of its O-H bonds ...
Purification and properties of trypsin-like enzyme from the midgut of morimus funereus (coleoptera, cerambycidae) larvae
(Wiley-Blackwell, Hoboken, 2010)
Trypsin-like enzyme (TLE) from the anterior midgut of Morimus funereus larvae was purified by anion exchange chromatography and gel filtration chromatography and characterized. Specific TLE activity was increased 322-fold ...
