Soft maps via soft somewhere dense sets
Authors: Al-Shami Tareq , Alshammari Ibtesam , Asaad Baravan
Published: March 2021

The concept of soft sets was proposed as an effective tool to deal with
uncertainty and vagueness. Topologists employed this concept to define and
study soft topological spaces. In this paper, we introduce the concepts of
soft SD-continuous, soft SD-open, soft SD-closed and soft SD-homeomorphism
maps by using soft somewhere dense and soft cs-dense sets. We characterize
them and discuss their main properties with the help of examples. In
particular, we investigate under what conditions the restriction of soft
SD-continuous, soft SD-open and soft SD-closed maps are respectively soft
SD-continuous, soft SD-open and soft SD-closed maps. We logically explain
the reasons of adding the null and absolute soft sets to the definitions of
soft SD-continuous and soft SD-closed maps, respectively, and removing the
null soft set from the definition of a soft SD-open map.

Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a
multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3?9H2O
were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared
mixture was thermally processed at 300?C for 6 h. Sintering at 1300?C for
1 h resulted in a mixture of different phases, BaTiO3, BaFe12O19 and
Ba12Ti28Fe15O84, which were confirmed by x-ray powder diffraction. A dense
microstructure with a small volume fraction of closed porosity was indicated
by the scanning electron microscopy, while a homogeneous distribution of Fe
ions over BaTiO3 phase was visible from energy dispersive spectroscopy
mapping. Doping of BaTiO3 with Fe2O3 resulted in formation of magnetic
hexaferrite phases, as confirmed by dielectric measurements that showed a
broadened maximum of the permittivity measured as a function of temperature.

Assessing influence of factors on interest risk of commercial bank
Authors: Markova Olga Mikhailovna
Published: March 2021

In modern conditions of the rapid industrial development the banks have to forecast their risks and profitability precisely, to apply information technologies to assess their activities. To evaluate the bank's income, it is necessary to carry out an internal analysis of its assets and liabilities and determine the factors effecting the bank's profitability by managing interest rate risk. The hypothesis of the study is the analysis of the impact on the net interest income and interest rate risk of a commercial bank of factors such as the exchange rate and the key rate of the Bank of Russia (for example, Sberbank, PJSC). There has been studied the impact of the factors (exchange rate and key interest rate of Central Bank of Russia) on the bank's net interest income by using correlation and regression analysis and building a regression model. Many tools are found to be used by the experienced analysts. One of the main tools is GAP analysis of interest rate risk. There have been illustrated the graphs of changes in interest rates of savings and loan associations during the crisis in the United States in the 1950-1960, of realization of interest rate risk with an increase in interest rates, the distribution of assets and liabilities according to the maturity of the balance sheet structure, the impact of changes in the interest rate GAP on net interest income, etc. A matrix of correlations of all variables in the sample (rates of growing values) was constructed. Conclusions are drawn on the need to use hedging instruments (interest rate swaps, interest rate options), as well as of attracting the most reliable data on the state of interest rate risk in the commercial banks.

Authors: Volynskiy Ilya Aleksandrovich
Published: March 2021

The article touches upon the problem of activating the international transport corridors bypassing Russia, which intensifies competition in the maritime transport market. The Russian Federation government has developed a state policy aimed at strengthening the position of national carriers on the basis of increased development of transport and logistics infrastructure, in particular, in the southern direction of the international transport corridor North – South. One of the mechanisms that allows to implement the state tasks is creating a special economic port zone in the Caspian Sea on the territory of the Astrakhan region, which provides for the modernization of existing high-tech transport and logistics infrastructure facilities and construction of new ones. The study of the geographical and socio-economic state of the Astrakhan region allowed systematizing the prerequisites for the creation of a special economic port zone and identifying the main areas of development: port and transport infrastructure, logistics services, attracting additional cargo flows and intensifying existing ones, integrating them into the international transport corridors. The construction of a new container terminal in the seaport of Olya makes it necessary to predict the volume of container cargo and ship traffic. The use of a combination of forecasting methods (expert assessments and an approximating function) has been justified; a forecasting method has been proposed to clarify the sequence and content of the forecasting stages; the analyses results for 2022-2050 are presented, which allow predicting the cash flows from the project implementation and determining the required amount of loading and unloading equipment, warehouse space and personnel.

Student Project Deaccessioning: A curatorial review
Authors: Smith Connor
Published: March 2021

Deaccessioning in collections can be controversial because of the value associated with some taxa and their conservational, historical, educational, display and research significance within the collection. Twenty-one horticultural institutions completed a survey on the protocols for deaccessioning plant material. The resulting data were collated to provide a comparison of the different approaches institutions take towards deaccessioning their collections. This study has identified that conservation and education are the most important factors in managing garden collections. Accession data of high quality is an essential part of managing a collection, but poor accession data should not be a reason to deaccession plants. Space constraints are the primary factor behind the deaccessioning of collections. This paper is a summary of the research project completed by the author for the BSc in Horticulture with Plantsmanship at the Royal Botanic Garden Edinburgh (RBGE).

Published: March 2021

Autologous blood eye drops have become an interesting, well-known, and widely used therapeutic option for many ocular surface diseases since their introduction into the ophthalmologic field forty-six years ago. The foundation for their use in the treatment of pathologies such as severe keratoconjunctivitis sicca, persistent epithelial defects, ocular chemical burns, recurrent epithelial erosions, Stevens-Johnson syndrome, ocular graft versus host disease, and, lately, in many other ocular surface conditions, relies on the fact that they contain proteins, vitamins, cytokines, and growth factors that participate in the signaling pathways of corneal epithelial healing in similar amounts to those found in normal, healthy tear films

Published: March 2021

Peculiarities of phytocoenotic association and and consortium relations of rare species of Gentiana lutea L., Gentiana punctata L., Gentiana acaulis L. are analyzed. All habitats of G. lutea populations are spatially associated with the bottoms of glacial cauldrons, krummholz with the species of Duschekia viridis (Chaix) DC, as well as herbaceous highland cenoses. These groups are autochthonous in terms of phytocenotic association of G. lutea. Most often, populations of G. lutea are part of the associations Pulmonario–Duschekietum viridis, Soldanello–Nardetum, in particular two of its subassociations: S.–N. gentianetosum, S.–N. narcissetosum, as well as subassociations Vaccinietum gentianosum, Calamagrostidetum gentianosum. Heavy pastoral load on highland cenoses led to the transformation of subassociations S.–N. gentianetosum and S.–N. Narcissetosum. Diagnostic species, Narcissus poeticus ssp. angustifolius (Curtis) Asch. et Graebn., G. lutea, in particular, have been replaced by dense-grained cereal Deschampsia cespitosa (L.) P. Beauv. The species of G. punctata tends to pine scrubs (Pinion mughi alliance), which are part of the alpine mat-grass (order Nardetalia), and also occur among subalpine shrub communities (Loiseleurio-Vaccinietea class), high-grass groups (Mulgedio-Aconitetea class) along the upper forest boundaries in riverbeds, descending into the forest belt (union Adenostylion alliariae). G. punctata is a diagnostic species of the endemic association Hyperico grisebachii – Calamagrostietum villosae and is a component part of the endemic associations Festucetum picturatae, Rhododendretum myrtifolii, a rare relict group of the ice age Centrario–Vaccinietum gaultherioides. The species composition of cenoses including G. punctata is also undergoing transformation affected by heavy pastoral load. In areas with heavy grazing, small clusters of G. punctata in the subalpine zone remain mostly in the gaps between the thickets of Pinus mugo Turra, D. viridis s and Juniperus communis subsp. nana. As in the case of G. lutea, the unfavourable species adjacent to G. punctata is D. saespitosa of high viability. Normal development of G. acaulis populations was found only in loosely coated cenoses comprised of Potentilla aurea L., Vaccinium myrtillus L., Festuca picturata Pils, Carex sempervirens Vill., Thymus sp., Anthoxanthum alpinum A. et D. Löve, as well as N. stricta and D. caespitosa (L.) Beauv. of low vitality. Adverse phytocenotic conditions for the growth of G. acaulis create species of D. viridis, Achillea submillefolium L., as well as N. stricta and D. caespitosa of high vitality. The consortia of the three species under study include 36 families of animals, with the varying degree of association: obligate (Apidae, Syrphidae, Formicidae, Diptera, Artropoda, Lumbricidae, Acariformes) and optional (Pieridae, Nymphalidae, Noridaidait, Gectuidae, Gectuidae, Chrysomelidae, Cantharididae, Alleculidae).
ВМІСТ ХЛОРОФІЛІВ І КАРОТИНОЇДІВ У ПАГОНАХ ЛОХИНИ ВИСОКОРОСЛОЇ (VACCINIUM CORYMBOSUM L.)

Published: March 2021

Since photosynthetic pigments are not only important for plants in photosynthesis,they are also biologically active substances in therapeutic usage, the search for plants with their high content remains an urgent task of nutraceuticals, pharmacy and medicine. In this study, the shoots of Vaccinium corymbosum L. varieties Bluejay (early ripening) and Bluecrop (medium ripening) grown in the experimental area in the Lviv region of Ukraine in the phenological phases: in flowering, fruiting, after fruiting, in preparation for winter dormancy have been used. 100 % acetone, 80 % acetone and diethyl ether were used as extractants. The content of chlorophylls and carotenoids was determined spectrophotometrically at wavelengths corresponding to their absorption maxima and calculated by formulas Holm-Wettstein, Lichtenthaler, Wintermans and de Mots.

The findings of the study show that the content of chlorophyll a and b in the shoots of V. corymbosum depends on the extractant and the phenological phase of growth at which the plant material is collected. The best extractant was 100 % acetone, slightly worse 80 % acetone and diethyl ether, although in general the level of chlorophylls coincided. All of the extractants used were effective enough to remove carotenoids. The content of chlorophylls and carotenoids and their ratio in the shoots of investigated varieties of V. corymbosum is high and varies during the growing season: the highest content of chlorophylls is observed during flowering: 45.45±7.384 and 37.89±2.849 mg/100 g of dry weight in Bluejay and Bluecrop respectively. The content of carotenoids increases from the flowering phase to fruiting and remains at the same level long after its completion. The highest content of carotenoids was 5.49±0.451 and 5.73±0,143 mg/100 g of dry weight in Bluejay and Bluecrop respectively. It is assumed that the dynamics of chlorophyll content reflects the increase in the level of energy needs of the plant to ensure generative reproduction during the fruiting phase, followed by preparation for changes in temperature and insolation in winter. Some evidence of this may be the increase in the ratio of chlorophylls a/b during this period.

In our opinion, further research on the use of P as a medicinal raw material would be beneficial, taking into account the given results.

Authors: Kelemenova Tatiana
Published: March 2021

Urgency of the research. There are several problems with resulting of measurement result related to validity and repeatability of measurement device. Toolmaker microscope has been verified for these characteristics. Target setting. Toolmakers microscope is as target device which is currently used for fast testing of manufactured prototype. Currently, it is necessary to know information about repeatability and validity of obtained results. Actual scientific researches and issues analysis. Producer did not provide the maximum permissible error MPE, so the aim of this work was to establish the actual MPE for this microscope. Also there is no mention about repeatability of this machine. Normally in accordance with standards, it is required to express results with also with measurement error or uncertainty of measurement. Uninvestigated parts of general matters defining. The main problem is with expressing of validity and repeatability of
measurement process. The minimum number of measurement has been established and also maximum permissible error has been identified. Producer provides own microscope etalon as calibration ruler and multiscale micrometer glass slide for microscope. The
question of the validity of these etalons are uninvestigated, because the next research will be focused to this problem. The research objective. Too log measurement process will unnecessarily over-price overall costs for measurement process. But insufficient number of measurements will decrease accuracy of measurement and overall uncertainty of measurement. Verification process of microscope has been executed for obtaining the information about maximum error of microscope. This information is also necessary for balance of the uncertainty of measurement made on this microscope.
The statement of basic materials. The probability distribution of measured values and number of minimum required number of measurement has been obtained from mentioned analysis. Conclusions. Validity and repeatability of measurement device bring the information how we can believe to measurement process with specified measurement device. Every measurement device should be verified for these
metrological properties. Repeatability obtained for examined microscope shows information about the number of measurement needed for effective measurement from the viewpoint of optimized inaccuracy and also from the viewpoint of economic costs. Measurement process is very expensive, so it is necessary to do economy optimization because of ability to be competitive on the market.
Textualisation of the Domestic Self: Hildagonda Duckitt’s Autobiographical Cookbook
Authors: Crous Marius , Murdoch Alan
Published: March 2021

Hilda’s Diary of a Cape Housekeeper (1902), by Hildagonda Duckitt, is an example of culinary literature and essentially a diary of life in the Cape at the time (one that includes recipes, notes on gardening, etc.). This text is investigated in this article with the aim of examining the responsibilities of women with respect to food, food preparation and the kitchen, the depiction of men with respect to food, its preparation and the eating thereof, and the influence of class and the ethnicity of the author’s intended audience. The article notes how these responsibilities have changed over time, particularly with regard to their content and appearance, as well as discusses the relationship between cookbooks and men. Cookbooks have become a mainstream subject of academic study, of popular culture and the media, not least of all for the insights that they provide about gender (especially in terms of the division of labour), ethnicity and culture, and while they have traditionally been aimed at white women, this is no longer always the case. Such gender issues are the primary focus of this article. The context of the book, namely South Africa under British colonial rule during the late 1800s and early 1900s, is also considered in order to shed light on the questions of ethnicity and culture. Duckitt’s affinity for the British Empire is explored, as well as her views about the indigenous people of South Africa, their roles with respect to food, and their place in the colonial home. Lastly, the article takes stock of Duckitt’s voracious appetite for new knowledge and its production, despite the patriarchy of the time.

The kidneys are bilaterally paired organs and serve several essential functions required to maintain a normal human physiological function. The renal size was conventionally determined on x-ray or urography by measuring the renal length distance of first lumbar vertebrae to third or fourth lumbar vertebrae. Ectopic position of the kidney can be associated with ureteric stone, vesicoureteric reflux and can predispose to iatrogenic trauma during interventional radiological and laparoscopic procedures and any surgeries. Therefore, it is important to know the variations between individuals in the level of kidney relative to the spinal column. The study aimed to analyse the morphometric and morphologic measurements of the kidney using CT angiogram in kidney donors. In this study, the length and breadth of kidney and different level of location of kidney in 100 renal donors were analysed. The study was conducted in specialised scan centres located in Chennai. Out of 100 kidney donors, 61% of them were male & 39% of them were female. The right kidney length was found to be 10.59 ±1.14 cms, and left kidney length was found to be 10.72 ± 1.22 cms. This report will be useful for transplant surgeries, as well as clinicians and radiologist who perform various techniques.

Biofilm associated infection causes higher mortality in catheterized patients. Identification of cupA gene in Pseudomonas aeruginosa coding for biofilm formation was selected as a primary objective. Synergistic antibacterial drugs (moxifloxacin-metronidazole) were prepared using the selected concentrations for coatings onto urinary catheter samples. Antibacterial coatings of synergistic antibacterial drugs onto a urinary catheter and its antibacterial activity were evaluated using the standard diffusion method. The drug coated catheters were investigated for their biocompatible properties. The biocompatibility of the drug coated samples was investigated on L929 fibroblast cell lines using MTT assay. The biofilm expressing genes (cupA gene) of the selected organism was detected using molecular methods. During the analysis, the cupA gene from the target organism was confirmed by the PCR method aided with the DNA electrophoresis process. The study was confirmed from the obtained DNA fragments of 172bp by comparing with 170bp fragment of reference bacterial strain. Quantitative antibacterial activity results showed that the drug coated catheter samples were significantly reduced the bacterial numbers. Biocompatibility of coated catheter samples evaluated by in-vitro  cell culture cytotoxicity assay exhibited no effect on cell viability of fibroblast cell lines. It is concluded that identifying biofilm expressing genes could help the health care workers to diagnose and treat the patients with an appropriate antibacterial agent.
