up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. graphene, a new class of 2d carbonaceous material with atom thi...

was to assess analytical issues surrounding the measurement of PSA in prostate cancer screening. A subsequent review article published earlier this year in the Annals of Clinical Biochemistry titled " Pre-and post-analytical factors that may influence use of serum prostate specific antigen and its isoforms in a screening programme for prostate cancer " 1 discusses the findings and draws from th...

Easily prepared nanoZnO was found to be as an efficient catalyst in the synthesis of 1,4-DHPs via four-component reaction of 1,3-dicarbonyls, aldehydes and ammonium carbonate in water at 60 °C. The prepared nanoZnO was characterized by XRD and FT-IR analysis, while the determined specific surface area of nano catalyst by BET method was 33 m2/g.

Alfalfa (Medicago sativa L.)-orchardgrass (Dactylis glomerata L.) hay was made in 96 large-round bales over 3 harvests during 2006 and 2007 to assess the effects of spontaneous heating on dry matter (DM) recovery, in vitro true digestibility (IVTD), and in situ disappearance kinetics of DM. Throughout these harvests, bales were made at preset diameters of 0.9, 1.2, or 1.5 m and at moisture conc...

We previously examined the cortical processing in response to somatosensory, auditory and noxious stimuli, using magnetoencephalography in humans. Here, we performed a similar analysis of the processing in the human visual cortex for comparative purposes. After flash stimuli applied to the right eye, activations were found in eight cortical areas: the left medial occipital area around the calca...

the effect of addition of qodumeh shahri (lepidium perfoliatum) seed gum on the emulsion properties were investigated in this study. l. perfoliatum seed gum with 0-0.6% (w/w) concentration was used together with 2% (w/w) wpc to emulsify 20% (w/w) corn oil. the emulsion was analyzed for emulsion stability, particle size, specific surface area, particle size distribution and rheological propertie...
