The reviewed images demonstrate the utility of SD-OCT in the identification of the unique characteristics of the presented retinal pathologies. SD-OCT is ideal for retinal layer localization of lesions, thus enhancing the differential diagnosis of retinal dots, spots, and other white lesions. Even though true pathognomonic patterns are rare, highly suggestive findings of certain retinal abnormalities often facilitate immediate recognition and diagnosis.
The sorption behavior and the physical and chemical forms of neptunium on the surface of minerals of the two chlorate samples, biotite and kaolin, with different contents of Fe(II) was studied. The liquid-liquid extraction and the X-ray photoelectron spectroscopy were employed to identify the valence forms of neptunium. On the basis of the obtained data the quantitative elemental composition of the surface of the studied minerals, as well as the ionic composition of the formed neptunium complexes was determined. It was shown that the Np(IV) and Np(VI) containing compounds did not form, while the complexes Np(V)O+ -hydroxyl did form on the surface. The oxygen ions bonded with iron and oxygen belonging to water and/or of carboxyl were suggested to be present in the equatorial plane of the neptunyl group NpO+
Handling of the industrial waste, including drilling waste is still one of the leading fields in the ecology area. The article considers utilization way of the bore mud consisting in application of safe components allowing getting of the ground suitable for the reclamation of disturbed lands. There was revealed that the content of physical clay (d < 0,01 mm) in the control sample (bore mud) is 6,58%, when applying the mixture of components in the bore mud. The decrease of physical clay is observed in the ground of A type (2 times) and B and C types (3 times). In the same time, in the grounds of all types, hydrophysical properties improve and gelation takes place. Composition of the studied total forms of heavy metals was on the level of maximum allowable concentrations for loam. Manganese concentration in the control sample was in the range from 69 to 93 mg/kg. Water extract from the grounds of all types has very strong influence on the test objects (Daphnia magna Straus), class of hazard for the environment is IV.
The decrease of the concentration of chloride-ions and sulphate-ions took place at the expense of replacement of Na + by cations of Ca 2+ that contributed to the formation of the water-stable structure with good filterability. The content of total forms of heavy metals in man-induced soil was lower than MAC (APC) for the loams. Man-induced soil has a V class of danger for the surrounding environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
