Comparison of four methods for the estimation of intracranial volume: A gold standard study
(Wiley, 2007)
Investigators can infer how much reduction in volume has occurred since brain volume was at its peak, by combining measures of brain volume with measures of intracranial volume (ICV). Several methodologies have been proposed ...
Decolourization and removal of some organic compounds from olive mill wastewater by advanced oxidation processes and lime treatment
(Springer Heidelberg, 2007)
Background. Olive mill wastewater (OMW) generated by the olive oil extracting industry is a major pollutant, because of its high organic load and phytotoxic and antibacterial phenolic compounds which resist biological ...
Comparison of three methods for the estimation of total intracranial volume - Stereologic, planimetric, and anthropometric approaches
(Lippincott Williams & Wilkins, 2007)
There is a well-known close relationship between the total intracranial volume (TIV) and the brain size. Several studies in different countries have estimated the cranial capacity, which indirectly reflects the brain volume. ...
Tourist harassment - A marketing perspective
(Pergamon-Elsevier Science Ltd, 2007)
Consumer services research contains few empirical studies of harassment involving tourists. Previous studies are largely in general typological terms. Relatively little is known about the effects of harassment on tourist ...
Comparative effects of various salicylic acid derivatives on key growth parameters and some enzyme activities in salinity stressed maize (Zea mays L.) plants
(Pakistan Botanical Soc, 2007)
Salicylic acid, 5-Sulfo Salicylic acid and Acetylsalicylic acid are Salicylic acid derivatives. They differ in their substitution on the benzene ring and m ay have different effects on plant 0 in membranes, The effects of ...
Spectrophotochemical and electrochemical characterization of perylene derivatives adsorbed on nanoporous metaloxide films
(Edp Sciences S A, 2007)
Electrochemistry of perylene imide and anhydride derivatives adsorbed on semiconductor TiO2 (NT) and insulator Al2O3 (NA) metal oxide films were presented. Adsorption rates on metal oxide surface are observed to be strongly ...
Design and construction of uniform glow discharge plasma system operating under atmospheric condition
(Amer Inst Physics, 2007)
The design of a uniform glow discharge plasma system operating without vacuum is presented. A full-bridge switching circuit was used to switch the transformers. The primary windings of transformers were connected in parallel, ...
Chionaeosides A-D, triterpene saponins from Paronychia chionaea
(Amer Chemical Soc, 2007)
Four new triterpenoid saponins, chionaeosides A-D (1-4) were isolated from the roots of Paronychia chionaea. On the basis of their spectroscopic data, the structures of the new saponins were established as 3-o-alpha-L-ar ...
Inhibition of quorum sensing-regulated behaviors by Scorzonera sandrasica
(Springer, 2007)
Many Gram-negative bacteria use N-acyl homoserine lactone signal molecules to monitor their own population density and coordinate gene regulation in a process called quorum sensing (QS). Increasing evidence implies that ...
Measurement and comparison of complex impedance of silicon p-i-n photodiodes at different temperatures
(Maik Nauka/Interperiodica/Springer, 2007)
The dark alternating current (ac) parameters of BPW34 and BPW41 (Vishay-Telefunken) silicon p-i-n photodiodes arc measured and compared at different temperatures using the impedance spectroscopy technique. The impedance ...
