MIRTALA PYLYPENKO’S COLLECTION IN THE MUSEUM OF HISTORY OF THE NATIONAL UNIVERSITY OF OSTROH ACADEMY
Authors: Kheleniuk Anastasia 
Published: March 2021

Special attention in this article is paid to the analysis of art collection of the Ukrainian artist from abroad Mirtala Pylypenko at the Museum of Ostroh Academy. In 1997 the Museum of history of the Ostroh Academy was founded. A great contribution to its development process was made by Ukrainians from abroad. They supported the museum, sent interesting exhibits, and joined in museum projects. Nowadays the museum has valuable art collections, among which sculptures of the well-known Ukrainian artist Mirtala Pylypenko. Mirtala Pylypenko was born in Ukraine. During World War II she emigrated, and since 1947 she has been living and working in the USA. She graduated from the Boston Museum’s Art School and Tufts University in Boston. Mirtala’s sculptures are not just artworks, but a profound philosophical and original vision of the world. She showed her talent not only in sculpture and art photography, but also in poetry – her poetic collections “Verses”, “Rainbow Bridge”, “Road to Oneself” have been published in various languages. Mirtala received acclaim in the US and Europe in the 1970s – 1980s. Since the early 1990s her works have been known in Ukraine, where the artist held a series of solo exhibits and presentations. Mirtala presented one collection of her works to the National University of Ostroh Academy. Now it is one of the most valuable collections in the university museum. As a sculptor with a long exhibiting career, Mirtala has combined images of her sculptures with her poems, creating a single whole, which is greater than its parts. Mirtala’s collection of sculptures is monumental, philosophic and gracious. However, at the same time, it is sunny and brings back the life-asserting symbols of eternal space and time. The artist has spent most of her life across the ocean (in the USA), but her soul remains tied to Ukraine. Mirtala Pylypenko is an extraordinary figure in the Ukrainian art. And now, many generations of university students have an opportunity to get acquainted with her unique talent. It is important that sooner or later, Ukraine reveals its artists. Therefore, the museum tries to return and represent the Ukrainian diaspora art and history in museum collections in order to create a single Ukrainian cultural space.

The aim of this study is to estimate the levels of serum uric acid in patients with acute myocardial infarction and also to study the correlation with Killip’s Classification of Cardiac failure. This is a cross sectional study, we selected the patients from ICCU and emergency department. 30 patients with AMI and age matched controls taken for study. Uric acid levels measured in Autoanalyzer Beckman Coulter AU 480. The mean serum uric acid among the study group and the control group on the day of admission (Day 0) was 7.6 ± 1.6 and 5.4 ± 1.2 respectively. There was a gradual increase in the SUA levels on Day 0, 3 and 7 and was proportionate with the increasing Killip’s class. It is concluded that the serum uric acid (SUA) levels are increased significantly among patients diagnosed with acute myocardial infarction (AMI)when compared with the controls. It is also evident that there is a significant correlation between SUA levels and the severity of the AMI based on the Killip’s classification. Higher the Killip’s class, higher the uric acid levels. Therefore, SUA shall be used as a marker in diagnosing and as a cofactor useful along with other clinical examinations and investigations to interpret the severity of AMI as well. However, additional work must be done to understand the full clinical potential of Uric acid and correlation with other cardiac failure parameters.

O Modelo Padrão e duas possíveis rotas de extensão
Authors: Belich H. , Leite E.V.B 
Published: March 2021

Simetrias e leis de conservação, e violação dessas simetrias são excelentes guias na formulação de modelos físicos em diversas escalas de energia. A violação de simetrias por transição de fase (violação espontânea de simetria) consegue descrever sistemas que vão desde a Matéria Condensada até a Física de Altas Energias. Nestas notas iremos apresentar um desenvolvimento conceitual de simetrias e suas violações usando inicialmente como exemplo a simetria global de rotação e sua violação espontânea de simetria global, por um fluido escalar gerando o ferromagnetismo. Usando como exemplo de transição a supercondutividade faremos um esboço do Mecanismo de Anderson-Higgs. Este mesmo mecanismo é utilizado para unificar o Eletromagnetismo e a interação Fraca no Modelo Padrão de Weinberg-Salam-Glashow. Finalizamos as notas apresentando duas propostas de extensão desse modelo: a Violação de Simetria de Lorentz dadas de duas maneiras: violação espontânea, e violação explícita por Teorias Não-Comutativas.
IMPROVEMENT DIRECTIONS OF THE MONETARY POLICY OF THE NATIONAL BANK OF THE REPUBLIC OF MOLDOVA WITH THE PURPOSE OF DEVELOPMENT OF THE NATIONAL ECONOMY
Authors: MİSTREAN Larisa 
Published: March 2021

The monetary policy of the central bank influences the amount of currency in circulation, the level of interest rates, foreign exchange rates and other economic-monetary indicators in order to achieve the general objectives of the economic policy, such as ensuring price stability by maintaining the inflation at an optimal level, the growth and the economic development of the country by stimulating economic activity, employment, etc.
The uncertain nature of the evolution of the world economy and the high degree of openness of the economy of the Republic of Moldova denotes a multitude of major risks that endanger the assurance and maintenance of the price stability. In the medium term, these remain to be large fluctuations in prices for food and energy resources, fluctuations in exchange rates of major currencies and of the capital flows. To cope with these situations, an important challenge for the monetary policy promoted by the NBM is to maintain inflationary expectations well anchored within the inflation target range.

The content of secondary metabolites in the rhizome of the Curcuma genus such as Black turmeric (Curcuma aeruginosa Roxb.), White turmeric (Curcuma zedoaria (Christm.) Roscoe) and Java turmeric (Curcuma xanthorrhiza Roxb.) play a role in various pharmacological activities. One of them is the content of the curcuminoid compounds which have been proved to have antibacterial activity. This study aims to screen the content of secondary metabolite compounds, determine curcuminoid content and verify the antibacterial activity of the extracts of Black turmeric (Curcuma aeruginosa Roxb.), White turmeric (Curcuma zedoaria (Christm.) Roscoe) and Java turmeric (Curcuma xanthorrhiza Roxb.). Extraction was carried out by the maceration method using 95% ethanol as solvent. Phytochemical screening was tested for the content of alkaloid, polyphenols, flavonoids, quinones, tannins, saponins, and steroids/ triterpenoids compounds. Determination of curcuminoid content by UV-Vis Spectrophotometry method. The antibacterial activity test was carried out by the microdilution method against Staphylococcus aureus, Staphylococcus epidermidis, and Propionibacterium acne bacteria. The results of phytochemical screening showed that the three extracts contained polyphenols and flavonoids. Quinone compounds are only contained in the extract of Black turmeric and Java turmeric. Saponin compounds were only detected in Black turmeric and White turmeric extracts. Meanwhile, steroid/ triterpenoid compounds were detected in the extract of White turmeric and Java turmeric. The results of curcuminoid content determination on the three extracts showed that the Java turmeric extract had the highest content of curcuminoids (16.07 ± 0.023 mg CE/g extract). The results of the antibacterial test showed the strongest activity of the three test samples shown by Java turmeric extract with a minimum inhibitory concentration (MIC) value of 64 mg/mL against Staphylococcus aureus bacteria; 256 mg/mL against Staphylococcus epidermidis bacteria; and 32 mg/mL against the Propionibacterium acne bacteria. These results indicate that Java turmeric extract is more active against Propionibacterium acne bacteria.

Published: March 2021

This effort is related to describe and assess the performance of the Iraqi cement sample planned for oil well-cementing jobs in Iraq. In this paper, major cementing properties which are thickening time, compressive strength, and free water in addition to the rheological properties and filtration of cement slurry underneath definite circumstances are experimentally tested. The consequences point to that the Iraqi cement after special additives encounter the requests of the API standards and can consequently is used in cementing jobs for oil wells. At this research, there is a comparative investigation established on experimental work on the effectiveness of some additives that considered as waste materials which are silica fume, bauxite, and glass powder, and other conventional additives which are: (SCR -100 Retarder, HR-5, FWCA, Hollow Glass Spheres (HGS) and Halad-9) that currently used in our fields on local Iraqi cement and putting foreign cement results as a governor. Chemical analysis for Iraqi cement, imported cement, and waste materials samples was determined using the X-ray fluorescence (XRF) technique and found minor differences in composition between those samples and depending on the results of X-ray, we selecting the appropriate additives to prepare cement slurry samples. The X-ray fluorescence (XRF) results show that Iraqi Cement has a low value of silica which is about 18.63% while Omani cement about 37.58%. This research examined the potential of micro silica, bauxite, and waste glass powder to produce sustainable cement slurry. The results showed that adding micro silica and bauxite enhances the performance of Iraqi cement but also leads to a slight decrease in thickening time. To avoid this problem, Superplasticizer is used to make the process of cement pumping more easily, in other words, increase thickening time and increase compressive strength. Furthermore, adding glass powder increase the value of compressive strength. Both additives (waste and conventional) are used for the slurry design for achieving better slurry properties, but waste additives increase and enhance Iraqi cement performance than conventional additives, in other words, making it more effective than commercial cement. Depending on the results of the compressive strength test, the optimal concentration of the waste materials used in this research was found, and then the optimal concentration was used to prepare cement samples. The results showed that the use of waste materials to prepare cement slurry is a promising way to improve the efficiency of cement work and to reduce the negative environmental impact resulting from the industry. The results of the program CemCADE proved to be the sample A and C showed good performance through high cement bonding and ideal distribution of fluids designed to accomplish the cementing process.

The Present Tense Usage in Speaking Skill: An Analysis of Students' Short Speech Texts
Authors: Hafni Hafsah  
Published: March 2021

The result of this paper is based on the data taken from Triskanedi (2007). The study result showed that 80% of students made mistakes in the use of simple present tense, which was the highest compared to the other two tenses, namely simple past and simple future tense. Due to these interesting findings, the writer intended to carry out further analysis by using the data of the research to find out the kinds of errors produced by the students focusing on simple present tense usage in the short speech texts. The analysis of the data uses a specific type of errors, i.e., omission, addition, missed formation and missed ordering/improper ordering in accordance to taxonomy strategy. The result shows the percentage of the omission of 'be and s/es' is 41.08%. While the addition of 'be and s/es' is 6,21%, and missed formation is 51,94%, and improper ordering is only 0,77%. The omission and addition seem related to the use of 'be' before an adjective or nominal sentence and's' in subject-verb agreement. In addition, the study also found few other errors in using of article 'the', verb inflexion 'ed', and of auxiliary in small numbers. These seems contributed to the students' errors production despite the fact that simple present tense considered as the easiest one to formulate compared to others, another thing that needs to underlie from this study is the understanding of English grammar seems necessary to avoid the same errors in the future

Background: Emerging evidence indicates that the misfolded tau protein can propagate aggregates between cells in a prion-like manner. This prion activity has been typically studied in brain extracts of patients with Alzheimer’s disease (AD), but not in the olfactory region that can be a potential biomarker in AD. Objective: To investigate the prion seeding activity of tau in nasal mucosa tissues using a cell culture model of tau propagation. Methods: Brain and nasal mucosa homogenates were added to HEK293T cells expressing three repeat or four-repeat domains of tau with the L266V, V337M (3RD*VM) and P301L and V377M mutations (4RD*LM) fused to the enhanced green fluorescence protein (EGFP) respectively. We also measured the level of phosphorylated tau (p-tau), total tau (t-tau), and p-tau/t-tau ratio and performed correlation analysis between tau prion activity and the level of tau. Results: We found that brain and nasal tissue homogenates from patients with AD significantly induced tau aggregation in HEK293T cells either expressing tau 3RD*VM-EGFP or 4RD*LM-EGFP compared with control brain and nasal tissue homogenates. The levels of p-tau and p-tau/t-tau ratio were significantly increased in the brain of patients with AD; however, no significant difference was found in nasal tissue compared with their respective control tissue homogenates. Conclusion: These results suggest that the nasal tissues contain tau seeds, similar to the brain, albeit without changes in the levels of p-tau and t-tau. Therefore, a cellular bioassay using nasal tissues would have great potential as an AD biomarker because of the usefulness of nasal tissue biopsy.

BACKGROUND: Recent advances in medical care have increased life expectancy and improved the quality of life for people with Down syndrome (DS). These advances are the result of both pre-clinical and clinical research but much about DS is still poorly understood. In 2020, the NIH announced their plan to update their DS research plan and requested input from the scientific and advocacy community. OBJECTIVE: The National Down Syndrome Society (NDSS) and the LuMind IDSC Foundation worked together with scientific and medical experts to develop recommendations for the NIH research plan. METHODS: NDSS and LuMind IDSC assembled over 50 experts across multiple disciplines and organized them in eleven working groups focused on specific issues for people with DS. RESULTS: This review article summarizes the research gaps and recommendations that have the potential to improve the health and quality of life for people with DS within the next decade. CONCLUSIONS: This review highlights many of the scientific gaps that exist in DS research. Based on these gaps, a multidisciplinary group of DS experts has made recommendations to advance DS research. This paper may also aid policymakers and the DS community to build a comprehensive national DS research strategy.

Published: March 2021

BACKGROUND: Virtual radiographic simulation has been found educationally effective for students to practice their clinical examinations remotely or online. A free available virtual simulator-ImaSim has received particular attention for radiographic science education because of its portability, free of charge and no constrain of location and physical facility. However, it lacks evidence to validate this virtual simulation software to faithfully reproduce radiographs comparable to that taken from a real X-ray machine to date. OBJECTIVE: To evaluate image quality of the virtual radiographs produced by the ImaSim. Thus, the deployment of this radiographic simulation software for teaching and experimental studying of radiography can be justified. METHODS: A real medical X-ray examination machine is employed to scan three standard QC phantoms to produce radiographs for comparing to the corresponding virtual radiographs generated by ImaSim software. The high and low range of radiographic contrast and comprehensive contrast-detail performance are considered to characterize the radiographic quality of the virtual simulation software. RESULTS: ImaSim software can generate radiographs with a contrast ranging from 30% to 0.8% and a spatial resolution as low as 0.6mm under the selected exposure setting condition. The characteristics of contrast and spatial resolution of virtual simulation generally agree with that of real medical X-ray examination machine. CONCLUSION: ImaSim software can be used to simulate a radiographic imaging process to generate radiographs with contrast and detail detectability comparable to those produced by a real X-ray imaging machine. Therefore, it can be adopted as a flexible educational tool for proof of concept and experimental design in radiography.
