background: paraquat is a non-selective contact herbicide, widely used to control weeds in agriculture farms and aquatic plants in surface waters. paraquat can have adverse effects on the health of aquatic organisms. the aim of this study was to detect the alterations in the blood biochemical parameters of common carp exposed to sub-lethal concentrations of commercial formulations of paraquat. ...

              The present work is focused on the degradation of 4-chloro-2-nitrophenol in aqueous solution containing nano titanium dioxide, hydrogen peroxide and the combination of nano-TiO2/H2O2. The effect of experimental parameters, such as the amount of nano- TiO2 concentration of H2O2, initial concentration of 4-chloro-...

OBJECTIVE To evaluate the patterns of cerebral cortical distribution of (11)C-PIB in patients with mild cognitive impairment (MCI). MATERIAL AND METHODS The study included 69 patients (37 male, age range 42-79 years) with MCI, sub-classified as 53 with amnestic-MCI (A-MCI), and 16 with non-amnestic-MCI (NA-MCI). Patients underwent (11)C-PIB PET/CT scan 60min after intravenous injection of the...

Three separate experiments were conducted to investigate the interplay between three phytohormones and sucrose for the change of flower color composition and the plant secondary metabolites in Tulipa. The variations of the physiological and morphological characteristics, with ABA at 5 and 10 mg/L (as experiment one), GA3 at 300 ‎and 500 mg/L ‏‎‎(as experiment two), 50 and 10...

In the presence of nuisance parameters, we derive an explicit higher order asymptotic formula to compare the expected lengths of conndence intervals given by likelihood ratio statistics arising from the usual proole likelihood and various adjustments thereof. Highest posterior density regions, with approximate frequentist validity, are also included in the study.

Introduction: An operational computed tomography (CT) scanner is a major source of human exposure to ionizing radiation. Exposure increases the risk of cancer and aplastic anaemia. All radiation exposures should be justified and optimized to meet the clinical objective. In order to avoid the administration of excessive radiation dose to patients, diagnostic reference l...

haraz-ghareh su is one of the seven sub-basins of the caspian basin, located on the southern shores of the caspian sea, and as such, is in danger of water crisis due to absence of proper systematic policy and strategy. in this study, the pressure factors on the haraz-ghareh su water resources were identified using dpsir model. then, the pressure parameters on the freshwater resources in the cas...

For hypotheses of the type H0 : θ = θ0 vs H1 : θ 6= θ0 we demonstrate the equivalence of a Bayesian hypothesis test using a Bayes factor and the corresponding classical test, for a large class of models, which are detailed in the paper. In particular, we show that the role of the prior and critical region for the Bayes factor test is only to specify the type I error. This is their only role sin...
