The aim of this study was to investigate the influence of long fibre concentration on loadability and pulp properties during LC refining of mechanical pulp. Long fibre concentration was adjusted to three different levels by screen fractionation of the pulp. The three pulps were refined in a single disc pilot scale LC refiner at similar process conditions. Increased long fibre concentration supp...

cyanobacteria blooms are common in baltic sea and their intensity have been increased due toanthropogenic eutrophication. in this study we investigated the cyanotoxin levels in the water samplescollected from four different locations in the baltic sea at three different seasons including summer 2011.protein phosphatase 2a (pp2a) inhibition assays, enzyme-linked immunosorbent assays (elisa) and ...

for the first time, a multi-residue methodfor simultaneous determination of 41lc-amenable pesticides in rice, belonging to different chemical classes has been developed in iran by lc-ms/ms. the pesticides were analyzed simultaneously in a single run using positive electrospray ionization with multiple reaction monitoring (mrm) after extraction with slightly modified quechers method. the calibra...

abstract   background: the survival curves generally have been used for analysis of cell survival under stress conditions. they depict the relationship between the fraction of cells retaining their reproductive integrity and the absorbed dose. the median lethal dose, lethal concentration, 50% (lc 50 ) of a  toxin ,  radiation , or  pathogen  is the  dose required to kill half the members of a t...

adequate bond strength between glass ionomer cements and composite resin is necessary for the success of the sandwich technique.this study assessed the micro-shear bond strength of composite resin to glass-ionomer cements (gic) using self-etch adhesives with different ph values.one hundred specimens (6×4×2 mm) were made using fuji ii and fuji ii lc gics and treated with different adhesives as f...

background as most hbv-related acute-on-chronic liver failure (aclf) have concurrent cirrhosis, it is important to clarify the association of viral factors with aclf with or without cirrhosis. objectives the aim of this study was to analyze the association of hbv genotypes and mutations with aclf development underlying different chronic liver diseases. patients and methods eighty-seven aclf pat...

objective: lc/na system is activator of hypothalamic–pituitar–adrenal (hpa) axis and cold stress triggers an equally robust increase in plasma na. increased lhrh content probably due to absence or decrease of ne release from the lc and positive feedback action of e2 on lh secretion show that in late proestrous phase na, lh and e2 have a strong link. this study was conducted to evaluate the effe...
