The literary topoi and allusions to the victim and sacrifice in the biblical and historical context at the same time played a great role for Andrey Kurbsky as a traditionalist and innovator writer in the embodiment of the complex author’s intention of the History of the Grand Prince of Moscow (the second half of the 16th century). The article notes that the writer distinguishes, as opposites, the axiology of sacrificial feat for power doer and persecuted heroes. The article reveals the diverse reception of the author’s interpretation by readers and scribes of History. Kurbsky’s contemporaries and readers of the late 17th — early 18th century had different attitudes toward Kurbsky’s definition of the personality of Ivan the Terrible who makes unrighteous victims and the characterization of people affected by him as new martyrs. The rich handwritten tradition of History, including as part of the Kurbsky Collections, contributed to the emergence of new reader’s interpretations based on literary topoi and allusions used by Kurbsky. The intellectuals of the ‘transitional’ period A.S. Matveev, Evfimy Chudovsky, A.I. Lyzlov, V.V. Golitsyn and others were involved in this process. Textological and typological comparisons of certain monuments and Kurbsky’s History contributed to a deeper understanding of the literary context of the time when the prince’s writings spread. The study also helped to determine which Kurbsky’s ideas about the victim and sacrifice remained relevant for members of different class groups, and which were leveled out and outdated in the text interpretation process.

ABSTRACTThe recent discovery of a Roman ceramics manufacturing workshop at Montelabate (Perugia, Italy), in use from the first century BC until the late-fourth to fifth centuries AD, offers a unique opportunity to study the technical processes for producing Roman amphorae. Ancient and modern clays were sampled and analysed; they do not differ significantly, supporting the hypothesis of the exploitation of the rich local clay source that allowed a continuity of production. Characterization of the clays was performed using geotechnical methods (Atterberg limits and size distribution) and by thermogravimetric and differential thermogravimetric analysis, Fourier-transform infrared spectroscopy, X-ray diffraction and X-ray fluorescence analyses. The material was suitable for pottery making with the addition of calcite and quartz sand temper. Production waste and discarded materials as well as good-quality products were also analysed with the same methodology. It is therefore possible to reconstruct the ancient technology by defining the recipe for the production of the amphorae and their firing temperature on the basis of the decomposition of clay materials and the presence of newly formed minerals.

The composites of expanded ghaphite with TiO2(EG/TiO2) have been prepared in the method of precursor mixing, and the optimum preparation conditions have been studied. The morphology and crystal structure of the EG/TiO2composites have been characterized by the means of SEM and XRD. Also their performance of decolorization for methyl orange solution has been researched. The results are shown as follows: the EG/TiO2composites maintain the rich porous and network structure of EG, and a lot of anatase TiO2particles widely distribute on surfaces and in layers of EG. Compared with TiO2sol, taking tetrabutyl titanate as titanium source, the prepared EG/TiO2composites have better performance. Increasing the added amount of tetrabutyl titanate, the decolorization rate of methyl orange solution increases at first, and then decreases. When adding 2 mL tetralbutyl titanate, the decolorization rate is at the peak, up to 98.4%. These results show the composites have excellent performance of decolorization for methyl orange solution. We suppose it is mainly due to the interaction between the adsorption of EG and the degradation of TiO2particles.

Fish waste management is one of the biggest impacts towards the environment. However, it is one of the rich sources of protein. Therefore, the aim of this study was to isolate and characterize acid soluble collagen (ASC) and pepsin soluble collagen (PSC) from shortfin scad (Decapterus macrosoma) waste, with the yields of ASC (3.35±3.43%) and PSC (0.10±0.13%) respectively. The isolated ASC and PSC from shortfin scad waste were characterized on chemical composition, protein concentration, structural properties by FTIR, solubility and morphology properties compared to the commercial collagen from tilapia (Oreochromis niloticus) scales. In terms of chemical composition, PSC showed better than ASC, since it contains comparatively higher in protein (26.97±1.02%) by Kjeldahl method and protein concentration (2.69±0.47 mg/mL) by biuret method, compared to ASC. The FTIR investigations also certified the existence of spacial triplehelical structures of collagens that are important for collagen backbones. Solubility results showed that both ASC and PSC are high insolubility at acidic pH with the lowest solubilisation point at the range of alkali condition. The morphological analysis of both ASC and PSC were almost similar too, as there were fibrils and porous structure. Therefore, collagen from shortfin scad waste, could be a useful alternative, with the potential to be used in food ingredient, biomedical, pharmaceutical and nutraceuticals industries

Thinopyrum intermedium (2n = 6x = 42, JJJSJSStSt) is one of the important resources for the wheat improvement. So far, a few Th. intermedium (Thi)-specific molecular markers have been reported, but the number is far from enough to meet the need of identifying alien fragments in wheat-Th. intermedium hybrids. In this study, 5,877,409 contigs were assembled using the Th. intermedium genotyping-by-sequencing (GBS) data. We obtained 5,452 non-redundant contigs containing mapped Thi-GBS markers with less than 20% similarity to the wheat genome and developed 2,019 sequence-tagged site (STS) molecular markers. Among the markers designed, 745 Thi-specific markers with amplification products in Th. intermedium but not in eight wheat landraces were further selected. The distribution of these markers in different homologous groups of Th. intermedium varied from 47 (7/12/28 on 6J/6St/6JS) to 183 (54/62/67 on 7J/7St/7JS). Furthermore, the effectiveness of these Thi-specific markers was verified using wheat-Th. intermedium partial amphidiploids, addition lines, substitution lines, and translocation lines. Markers developed in this study provide a convenient, rapid, reliable, and economical method for identifying Th. intermedium chromosomes in wheat. In addition, this set of Thi-specific markers can also be used to estimate genetic and physical locations of Th. intermedium chromatin in the introgression lines, thus providing valuable information for follow-up studies such as alien gene mining.

ABSTRACTOpen framework materials are of great interest due to the applications in the fields of adsorption, ion exchange, molecular sieving and catalysis. Metal phosphates are very important open framework materials due to the rich crystallography. Several new iron phosphate materials have been synthesized and characterized in our lab. Two new iron (III) phosphates, FePO4, have been synthesized from careful dehydration of hydrothermally prepared monoclinic and orthorhombic hydrated phosphates FePO4·2H2O. Reversible insertion and extraction of lithium into new iron phosphate hydroxide materials with 3-d rod-packing framework shows it to be an excellent intercalation material. Several other transition metals are also incorporated successfully into these compounds without changing the structure. With ethylenediamine as template, 1-D chain, 2-D layered and 3-D network iron phosphate materials were synthesized. The structure, electrochemical and magnetic properties of these compounds were studied. Meanwhile, two new zinc phosphates with methylammonium templates were also synthesized. There are infinite Zn-O-Zn chains in one of the compounds, while closed 4-member circuits made up from Zn-O-Zn linkage present in the other.

FT-IR characterization of pollen biochemistry was analyzed to detect possible connection with the viability (by staining with potassium iodide, 25%) and the germination capacity (on solid nutrient medium), in 15Saintpauliagenotypes. Vibrational spectroscopy indicates that the pollen ofS. ionanthagenotype “Red Velvet” is rich in proteins, lipids, triglycerides, and esters and has a viability of 88.4% and a low germination capacity (27.16%). ForS. ionantha“Jolly Red” and “Lucky Ladybug” genotypes, pollen showed high viability (88.81–91.49%) and low germination capacity (23.02–9.17%), even though the pollen is rich in carbohydrates.S. ionantha“Aloha Orchid” genotype has the highest percentage of viability (94.32%) and germination capacity (45.73%) and a rich content of carbohydrates and polygalacturonic acids. InS. rupicolaandS. ionanthagenotypes, the rich content of polygalacturonic acids, lipids, and carbohydrates favourably influenced the germination capacity. Spectroscopic result indicates, through different absorbance band intensity, a possible link between biochemical composition, viability, and germination capacity ofSaintpauliapollen. To determine exactly the relation between biochemistry and biological processes, it is necessary to initiate quantitative researches.
