This study investigated the photo-degradation of methyl orange (MO) as a type of azo dye using a CuO/α-Fe2O3 nanocomposite. A CuO/α-Fe2O3 powder with a crystalline size in the range of 27-49 nm was successfully prepared using simple co-precipitation along with a sonication method. The characterization of the synthesized sample was done via XRD, FE-SEM, EDS, FTIR and DRS analyses. The Tauc equat...

some children of borazjan area have minute white flecks, yellow or brown spot areas scattered irregularly over the tooth surface, the causative factor was attributed to excess of fluoride in water. to verify this matter short chemical examination of water samples from endemic area was carried out. the results of water analysis by colorimetric method, using zirconium a1izarin reagent after disti...

this study presents the synthesis of polyvinyl acetate (pvac) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (pva) using alkaline alcoholysis. the influence of the molar ratio of hydrolysis catalyst (naoh) to pvac and the time and temperature of the saponification reaction on the degree of hydrolysis and molecular weight of the pva were investigated using response su...

Cells normally respond to a lack of nutrients by activating autophagy, a prominent pro-survival pathway that involves the catabolism and recycling of cytoplasmic material. Recent results indicate that mitochondria actively elongate during autophagy, thereby avoiding their degradation and sustaining cell viability.

Intensively reared piglets may face many early life challenges and these may affect behavior. The objective of this study was to examine the relationship between piglets' early life circumstances and their behavioral response in a backtest. Here, 992 piglets of 14 d of age were subjected to a backtest, in which they were restrained for 1 min in a supine position. The number of struggles in the ...

Hypoxia (low O2) is a common and natural feature of many marine environments. However, human-induced hypoxia has been on the rise over the past half century and is now recognised as a major problem in the world's seas and oceans. Whilst we have information on how marine invertebrates respond physiologically to hypoxia in the laboratory, we still lack understanding of how they respond to such st...

HE term canalisation will be used here to describe a developmental buffering system which acts to reduce potential variation and produce a less variable phenotype. Unless such a system acts at the gene level it would act on variation due to either genotype or environment and canalising selection can aim at reducing the response to either genetic or environmental variation. Selection for canalis...

Studying mechanical deformation at the surface of soft materials has been challenging due to the difficulty in separating surface deformation from the bulk elasticity of the materials. Here, we introduce a new approach for studying the surface mechanical deformation of a soft material by utilizing a large number of self-propelled microprobes driven by motor proteins on the surface of the materi...
