While systemic corticosteroids quicken patient recovery during acute exacerbations of COPD, they also have many adverse effects. The optimal duration of corticosteroid administration remains uncertain. We performed a systematic review and meta-analysis to compare patient outcomes between short- (≤7 days) and long- (>7 days) corticosteroid regimens in adults with acute exacerbations of COPD. MEDLINE, EMBASE, CENTRAL, and hand searches were used to identify eligible studies. Risk of bias was assessed using the Cochrane RoB 2.0 tool and ROBINS-I. Data were summarized as ORs (odds ratios) or MDs (mean differences) whenever possible and qualitatively described otherwise. A total of 11532 participants from eight RCTs and three retrospective cohort studies were included, with 1296 from seven RCTs and two cohort studies eligible for meta-analyses. Heterogeneity was present in the methodology and settings of the studies. The OR (using short duration as the treatment arm) for mortality was 0.76 (95% CI = 0.40–1.44, n = 1055). The MD for hospital length-of-stay was -0.91 days (95% CI = -1.81–-0.02 days, n = 421). The OR for re-exacerbations was 1.31 (95% CI = 0.90–1.90, n = 552). The OR for hyperglycemia was 0.90 (95% CI = 0.60–1.33, n = 423). The OR for infection incidence was 0.96 (95% CI = 0.59–1.156, n = 389). The MD for one-second forced expiratory volume change was -18.40 mL (95% CI = -111.80–75.01 mL, n = 161). The RCTs generally had low or unclear risks of bias, while the cohort studies had serious or moderate risks of bias. Our meta-analyses were affected by imprecision due to insufficient data. Some heterogeneity was present in the results, suggesting population, setting, and treatment details are potential prognostic factors. Our evidence suggests that short-duration treatments are not worse than long-duration treatments in moderate/severe exacerbations and may lead to considerably better outcomes in milder exacerbations. This supports the current GOLD guidelines.

Background and Aim: Bovine subclinical mastitis (SCM) is highly prevalent among dairy cattle. A cross-sectional study was conducted in Bangladesh to evaluate the performance of electric conductivity (EC) and total dissolved solids (TDS) tests for the detection of SCM.

Materials and Methods: We randomly selected 108 milk samples from cows of different breeds in the primary milk-producing region of Pabna and Sirajgonj districts of Bangladesh. Samples were subjected to the California mastitis test (CMT), white side test (WST), electric conductivity (EC), TDS, and culture. A cow was considered positive for SCM if it tested positive in CMT, WST, and culture, whereas a cow was considered negative for SCM if it tested negative in all three methods. These gold standards have been used to evaluate the performance of the EC and TDS tests. The optimal EC and TDS cutoff values for the detection of SCM were determined using the “optimal cutoff” function in R version 4.3.1.

Results: The optimal EC cutoff value for SCM detection was found to be 6159 μS/cm or 6.16 mS/cm. A positive likelihood ratio (LR+) of 31.2 and an area under the curve (AUC) of 0.905 were obtained for this cutoff value. The optimal cutoff value for TDS was 3100 mg/L of milk, which resulted in a positive LR+ of 45.5 and an AUC of 0.924.

Conclusion: To the best of our knowledge, this is the first study to evaluate the performance of EC and TDS tests in detecting SCM in Bangladesh. These results suggest that EC and TDS tests, which are inexpensive, rapid, and easy to conduct, can effectively detect SCM at the farm level.

Keywords: Bangladesh, cutoff value, electric conductivity, subclinical mastitis, total dissolved solid.

Relationship and Attributive Impact of Self-Regulation, Language Learning Strategies, and Second Language Anxiety to Second Language Learning of Grade 11 Students
Authors: Cordero Angelie Lyn , Santos Jr. Bayani
Published: December 2023

Second language (L2) learning is a complex process for language learners, which is evident in the language performance of Filipino learners who are performing poorly in writing and reading in English. Based on several studies with findings that corroborate the influence of self-regulation, Language Learning Strategies (LSS), and L2/ESL anxiety on L2 learning, the present descriptive-correlational study aimed to determine the relationship and attributive impact of self-regulation, LLS, and L2/ESL anxiety on L2 learning in a defined Philippine university. The data were collected from 447 Grade 11 participants using questionnaires. The collected data were analyzed using mean, Pearson’s correlation coefficient, and multiple regression analysis. The findings revealed that self-regulation has a weak positive significant correlation with L2 learning, while LLS and L2/ESL anxiety have no significant relationship with L2 learning. As for the attributive impact, the findings suggested that self-regulation is directly proportional to L2 learning, and LLS are indirectly proportional to L2 learning. As for L2/ESL anxiety, it has no significant impact on L2 learning. The findings became the basis of the recommended strategies for second language teachers.

Published: December 2023

The incidence of anemia due to reactive oxygen species (ROS) in patients with head and neck cancer (HNC) can be caused by a side effect of cisplatin chemotherapy, namely myelosuppression. In the presence of ROS, external antioxidants are needed, including astaxanthin as an antioxidant to neutralize and fight ROS in preventing anemia. This study aims to prove and analyze the antioxidant effect of astaxanthin in preventing anemia in HNC patients due to cisplatin chemotherapy for 3 weeks. The study design was a randomized controlled trial pre-post test design, involving 42 research subjects who were randomly divided into two groups, then 3 cc of blood was taken I to check the hemoglobin level and the number of erythrocytes. The treatment group was given astaxanthin 2x4 mg and the control group was given a combination of vitamin C 1x500 mg and vitamin E 1x250 IU for 3 weeks then 3 cc of blood was taken II to check hemoglobin levels and erythrocyte counts. The independent variable is intake of astaxanthin, the dependent variable is hemoglobin level and the number of erythrocytes and the confounding variables are age, sex, type of HNC, stage of HNC, ECOG and BMI. Data analysis was performed by the Descriptive test, Levene test, Shapiro Wilks, Wilcoxon test, and Mann-Whitney test. The significance of the hypothesis test was obtained with p<0.05. The 42 research subjects met the inclusion criteria, most aged between 41-50 years, male and female ratio 2:1, The most HNC were Nasopharyngeal Cancer, the most HNC stage was stage IV, the most HNC performance status was ECOG I and the most HNC patients had normal BMI. There was a significant difference in hemoglobin levels p=0.012 (p<0.05) and the number of erythrocytes, p=0.04 (p<0.05) between the treatment and control groups. There was a significant difference in hemoglobin levels after therapy in the treatment and control groups p=0.012 (p<0.05) and the number of erythrocytes p=0.04 (p<0.05) between the treatment and control groups. Astaxanthin can prevent anemia in the form of decreased hemoglobin levels and the number of erythrocytes in HNC patients who receive cisplatin chemotherapy.Keywords: astaxanthin, anemia, HNC, cisplatin, ROS.

Published: December 2023

Job satisfaction is a positive emotional condition as a result of job appraisal. Spirituality possessed by a doctor is an inner condition that grows because it interprets work in his life. This study aims to examine and explain the relationship between job satisfaction and physician performance, which is moderated by spirituality. From the questionnaires that were distributed, a total of 150 respondents were obtained consisting of general practitioners (71 people), doctors with Masters degrees (65 people), specialist doctors (9 people) and doctors with Doctoral education as many as 5 people. The doctors have worked for < 5 years (63 people), 5-10 years (32 people), 10-20 years (31 people) and > 20 years (24 people). The results of the construct validity test (job satisfaction) obtained data that there were 5 valid statement indicators. While the validity of spirituality obtained 4 valid data, and on the performance, parameters obtained 6 valid performance indicators. The results of the analysis obtained data that job satisfaction has a positive significant effect on the performance of doctors (P = 0.000). Spirituality has a positive significant effect on doctors' performance with a significance level of P=0.000. However, spirituality as a moderating variable has a negative effect, which means it reduces the effect of job satisfaction on performance. The spirituality factor reduces job satisfaction. It can be logically explained that job satisfaction is not solely a determinant of performance. Spirituality reflects the vocation of dedication as a doctor who has special knowledge to help human health and humanity. Spiritually, working doctors do not pursue job satisfaction merely, but there is a spirituality of dedication that aims to help save the souls of fellow human beings.
Fluorescent Probes for Monitoring Cholesterol Trafficking in Cells
Authors: Králová Jarmila , Král V.
Published: December 2023

Cellular cholesterol plays fundamental and diverse roles in many biological processes and affects the pathology of various diseases. Comprehensive and detailed understanding of the cellular functions and characteristics of cholesterol requires visualization of its subcellular distribution, which can be achieved by fluorescence microscopy. Many attempts have been made to develop fluorescent cholesterol reporters, but so far, none of them seems to be ideal for studying all aspects of cholesterol management. To meet the requirements for the right probe remains a great challenge, and progress in this field continues. The main objective of this review is to not only present the current state of the art, but also critically evaluate the applicability of individual probes and for what purpose they can be used to obtain relevant data. Hence, the data obtained with different probes might provide complementary information to build an integrated picture about the cellular cholesterol.

Published: December 2023

During the last decades, plant extracts containing phytoestrogens have increasingly been used as an alternative to oestradiol hormone replacement therapy. The aim of the present study was to compare the effects of genistein with those of different phytoestrogen-containing plant extracts (from red clover flowers and soybeans) on the proliferation and differentiation of NIH-3T3, HaCaT and MCF-7 cells. Our results showed poor correlations between direct anti/pro-oxidant effects and cytotoxicity of the tested samples. In contrast, genistein showed a direct correlation between significant pro-oxidative effects at cytotoxic concentrations and almost no pro-oxidative effects at non-cytotoxic concentrations. Moreover, the tested red clover extract and genistein induced keratin-8 (luminal and prognostic marker in breast cancer) expression only in MCF-7 cells, but this effect was not seen following treatment with the soybean extract. From this point of view, the effect of consumption of phytoestrogens in oestrogen-positive breast cancer remains to be elucidated. In conclusion, our study demonstrates that various phytoestrogen- containing plant extracts and genistein are able to specifically modulate antioxidant properties and differentiation of studied cells.
Angas-Sura etymologies XIII
Authors: Takács Gábor
Published: December 2023

The paper as part of a long-running series is devoted to the etymological analysis of a new segment (namely that with initial dental *d-) of the Angas-Sura root stock, a small group of modern languages remotely and ultimately akin to pharaonic Egyptian and the well-known Semitic languages or Twareg in the Sahara etc. Doing so, I wish to continue the noble tradition initiated by J.H. Greenberg (1958), the founding father of modern Afro-Asiatic comparative linguistics (along with I.M. Diakonoff), who was the first scholar ever to have established by Neo-Grammarian the methods regular consonantal correspondences between Angas-Sura (AS) and ancient Egyptian in his pioneering (painfully isolated) paper on the ancient trichotomy of the word-initial labials in both branches. Nowadays our chances in following this path are substantially more favourable being equipped with our gigantic comparative root catalogue system of the Egyptian etymologies ever published (ongoing since 1994) and of the Afro-Asiatic parental lexical stock (ongoing since 1999). This series of papers represents the author’s ongoing project for an etymological dictionary of  the Angas-Sura languages comprising their entire Afro-Asiatic cognacy.
BCLM: a novel chaotic map for designing cryptography-based security mechanism for IEEE C37.118.2 PMU communication in smart grid
Authors: Soni Rajkumar , Thukral Manish Kumar , Kanwar Neeraj
Published: December 2023

Today, creating a smart grid that is resistant to cyberattacks is a subject of utmost significance. One of the components of the smart grid that is most susceptible to a cyber-attack is the phasor measuring unit (PMU). The reason is that PMU employs IEEE C37.118.2 communication standards, which specify the structure and sequencing of data packets but offer no security measures. Users must implement the security techniques to ensure the protection of PMU data. Additionally, PMU communicates via a public wide-area network, raising the risk to security. In addition, PMU is a crucial component of the smart grid, enabling different crucial choices for the reliable functioning of the smart grid to be made using its data. This research suggests a chaos-based data encryption solution to close the knowledge gap and reduce the confidentiality assault on PMU data. For this, a brand-new boost converter logarithmic map (BCLM), a one-dimensional (1D) chaotic map, has been presented. The research demonstrates how the suggested chaotic map has better chaotic qualities than conventional chaotic maps. The pseudorandom generator is the chaotic BCLM system. The PMU data are encrypted using the random sequence produced by the BCLM chaotic system. The suggested chaotic map is not computationally demanding, making it simple to implement in a PMU device with limited resources.

Published: December 2023

Refractance window drying (RWD) is a preferred drying technique due to its suitability for heat-sensitive products. Although this drying technique appears promising, it is yet largely unexplored. In this study, the authors provide a review of the existing milestones on RWD using a sample of 40 articles from 2000 to date to quantify the state of investigations across multiple studies and establish specific areas needing further attention. Results show that experimental analyses constitute about 53–59 % of the reported cases, followed by a literature review 24–28 %. Furthermore, 17 % of the total study cases was observed across all modelling categories, with machine learning (ML) techniques constituting only about 8 %. Driven by the outcome, this study thus utilized three ML techniques to model the moisture ratio (MR) of 1.5–4.5 mm thick yam slices, operated over the range of 65–95 °C temperature in an RWD chamber. Unlike the routine procedures, the yam thickness versus air temperature effects on moisture ratio were investigated to determine the more significant factor as well as the air velocity effect or its lack thereof on MR. To investigate the validity window for the entire dataset, all data points were considered, with a training-testing ratio of 7:3 used in each case. For scenario one, prediction based on the yam thickness effect showed a greater influence on the MR. The air velocities at 0.5–1.5 m/s had little effect on MR as compared to the case where air velocity was ignored (i.e., the control case in this study). Also, model accuracy for all tested samples has been determined to be better than 93 %. Insight from this study is to guide in the future design of RW dryers for direct measurement of the moisture ratio of harvested root tubers at various conditions.

Published: December 2023

The Mesolithic burial site Groß Fredenwalde, NE-Germany, discovered in 1962, had remained a poorly understood part of the Mesolithic burial record for decades. Since 2012, the site has been under re-investigation. New discoveries confirm the presence of several single and multiple inhumation graves. Groß Fredenwalde stands out as the largest and one of the oldest Mesolithic cemeteries in North-central Europe. Its use period can be separated into two phases: a main phase in the late seventh millennium cal BC to the early sixth millennium cal BC and a later single burial c. 4900 cal BC. Here the state of research on the site is presented and selected characteristics are discussed in the context of early cemeteries of Northern and North-eastern Europe.
Escape from X-chromosome inactivation and sex differences in Alzheimer’s disease
Authors: Song Qing-Hua , Zhao Ke-Xuan , Huang Shuai , Chen Tong , He Ling
Published: December 2023

Sex differences exist in the onset and progression of Alzheimer’s disease. Globally, women have a higher prevalence, while men with Alzheimer’s disease experience earlier mortality and more pronounced cognitive decline than women. The cause of sex differences in Alzheimer’s disease remains unclear. Accumulating evidence suggests the potential role of X-linked genetic factors in the sex difference of Alzheimer’s disease (AD). During embryogenesis, a remarkable process known as X-chromosome inactivation (XCI) occurs in females, leading to one of the X chromosomes undergoing transcriptional inactivation, which balances the effects of two X chromosomes in females. Nevertheless, certain genes exceptionally escape from XCI, which provides a basis for dual expression dosage of specific genes in females. Based on recent research findings, we explore key escape genes and their potential therapeutic use associated with Alzheimer’s disease. Also, we discuss their possible role in driving the sex differences in Alzheimer’s disease. This will provide new perspectives for precision medicine and gender-specific treatment of AD.
Feminističko čitanje poezije Marije Čudine
Authors: Anđelić Andrea
Published: December 2023

Rad nudi interpretaciju zbirke Nestvarne djevojčice Marije Čudine iz 1959. godine, a fokusiran je na čitanje tematsko-motivskoga sloja pjesme iz feminističke perspektive te razmatranje odnosa lirskoga subjekta zbirke prema pitanjima roda, seksualnosti i reprodukcije. Krenuvši od problematike ženskoga pisma i statusa ženske književnosti u hrvatskom (i šire, zapadnom) književnom kanonu, jedan je od ciljeva teksta potaknuti feministički zadano prevrednovanje hrvatske ženske poezije koje neće polaziti od ustaljenih kategorija, već će predložiti nove perspektive čitanja i analize koje su dosadašnji kritičari i povjesničari književnosti previdjeli. S obzirom na to, naglasak ovoga tumačenja na doživljajima je lirskoga subjekta koji se nalazi u poziciji između djetinjstva i odraslosti, poziciji koja u njemu izaziva egzistencijalni i emocionalni rascjep te otuđenje. U fokusu su istraživanja pjesnički iskazi o doživljajima rodne determiniranosti subjekta i rodnoga identiteta kao diskurzivne pozicije koja se svakome subjektu dodjeljuje upravo tijekom razdoblja odrastanja. Tekstualnom analizom nekolicine pjesama iz zbirke želi se ukazati na to da upravo u specifičnoj rodnoj i emocionalnoj obilježenosti lirskoga subjekta leži potencijal zbirke da bude čitana kao važan dio hrvatskoga kanona, a osobito parakanona, te osvijetliti važnost Čudinina pjesništva u kontekstu suvremene hrvatske poezije.
Istantanee d’Oriente
Authors: Bencini Camilla
Published: December 2023

Nel panorama della letteratura italiana otto-novecentesca Edmondo De Amicis (1846-1908) ha enormemente concorso ad ampliare l’orizzonte culturale e geografico degli italiani, grazie ai reportages di viaggio frutto delle sue corrispondenze giornalistiche. Tra i risultati delle sue esplorazioni, raccolte poi in fortunate pubblicazioni tra le quali si ricordano la Spagna (1873), l’Olanda (1874), i Ricordi di Londra (1874) ed il Marocco (1876), l’opera Costantinopoli rappresenta un caso peculiare. Il volume, edito per i tipi di Treves nel 1877, che nelle intenzioni dell’autore avrebbe dovuto essere l’”último libro de viaje” ha contribuito in maniera decisiva a formare e diffondere l’immaginario ottomano fin de siècle dall’Italia in Europa. A tre anni dalla cura della traduzione croata del volume deamicisiano del 1883, Adolf Veber Tkalčević nel suo personale Viaggio a Costantinopoli (1886) affermerà: “neanche l’osservatore più critico oserebbe aggiungere qualcosa, De Amicis l’ha descritta così bene, come nessun altro” (A. V. Tkalčević, Put u Carigrad, Zagreb, 1886, p. 91). Il contributo indaga le sorti del felice caso editoriale del diario di viaggio e pone l’attenzione sulle “istantanee” narrative della città imperiale, nell’ottica di una rinnovata attenzione al testo e alla narrativa odeporica dell’autore italiano.
Synthesis and Characterization of Optical Properties of Carbon Quantum Dots (CQD) Based on Mustard Green (Brassica juncea L) Leaf with Urea Addition
Authors: Yuniarti Elvan , Nurlaela Ai
Published: December 2023

Carbon quantum dots (CQDs) are a class of fluorescent carbon nanomaterials. Carbon quantum dots (CQDs) were synthesized in this work from Mustard Leaves (Brassica juncea L) with the Addition of Urea via a microwave-assisted reflux method. This research aims to characterize CQDs' optical properties, energy gap, and emission under UV light computationally and experimentally. The studied optical properties obtained the maximum absorption peak observed from the UV-Vis spectrum of CQDs without urea shown at 233 nm. The UV-Vis spectrum of CQDs with the addition of urea (1 g, 1.5 g, and 2 g urea) has maximum absorption peaks at 424 nm, 422 nm, and 418 nm. The addition of urea causes a shift in the peak of the UV-Vis absorption spectrum towards red wavelengths (redshift). CQDs display bright green emissions when exposed to UV irradiation. In this work, the structures of CQDs of various forms (CQD-24, CQD-54, CQD-24-NH2, CQD-54-NH2) are theoretically studied in detail, and the results present both models (CQD-24, CQD-54) shows that the calculation results are in accordance with the experimental results, namely having a maximum UV-Vis absorption at 233 nm and in the range 200-400 nm. The results of calculations based on experiments show the same trend, namely that with the addition of urea, there is a shift in the absorption peak (redshift). The gap energy obtained also decreased with the addition of urea. CQDs solution emits yellow-green light.

Using soil planting media with low fertility can inhibit seedling growth. Bbiofertilizer and organic fertilizer applications in plantation nurseries aim to improve the planting media quality and stimulate seedling growth. The effectiveness of biofertilizers is thought to be influenced by the carrier formula and the planting medium characteristics. This study aimed to determine the effect of biofertilizer formulas and organic fertilizer doses on the growth of Arabica coffee seedlings and the planting media chemical properties. The experiment used a randomized block design with two factors. The first factor was biofertilizer formula types, namely without biofertilizers, 10 g polybag-1 solid biofertilizer, and 10 ml polybag-1 liquid biofertilizer. The second factor was sheep manure dosage (2%, 4%, 6%, and 8%). The results showed that the solid biofertilizers significantly increased seed vigor (height, stem diameter, and number of leaves) of coffee seedlings aged 6 MAP (months after planting). The dose of 6% manure produced the highest leaf dry weight of coffee seedlings aged 6 MAP. Increasing the dose of manure from 2% to 8% could significantly increase the pH, organic C content, P-available, CEC, exchangeable pottasium, exchangeable calsium, and exchangeable magnesium of the planting medium. The application of solid biofertilizer formula and manure can support the production of good-quality Arabica coffee seedlings.ABSTRAKPenggunaan media tanam tanah dengan kualitas kesuburan yang rendah dapat menghambat pertumbuhan bibit.

Even though whey has a low energy value among dairy products, it is at the same time very valuable biologically. Recently, the consumption of berries has increased markedly everywhere. This growth is explained by the growing attention of the population to health and the appearance on the market of many canned products "saturated with berries". In addition, there are many scientific studies concerning the composition of biologically active components in the composition of berries. Thus, scientific developments to produce new foods enriched with berries are of crucial importance for berry producers, food processors and consumers.
The scientific novelty of this study is to investigate the possibility of using wild plant raw materials of Northern Kazakhstan (chokeberry and saskatoon berry) in milk beverages’ technology, that will be described for the first time. This berries despite their rich chemical composition, are rarely used in the food industry. The study describes the nutritional value and chemical composition of whey drinks enriched with juice from saskatoon berries, black chokeberry.
In our study it is proposed thermosaltic coagulation as a primary treatment for whey. The comparative analyses of natural whey and treated one shows the expediency and benefit of using thermosaltic coagulation. At the same time, juices from wild berries increase the biological and nutritional value of whey drinks Thus, the described advantages are confirmed with assays and confirm the expediency of using this combined technology in the production of drinks from whey with berry juices.
The obtained research results will be used to develop a new technology to produce juice drinks based on whey and will also be described in a patent for a utility model for the production of beverages from whey

In today's world, the issue of creating complete food products is relevant for the development of food technology. One of these areas is devoted to solving the problem of preventing iron deficiency conditions arising from iron deficiency in the diet.
To enrich the diet with necessary nutrients and reduce the loss of valuable raw materials, it is relevant to justify innovative technologies of sausage products.
The object of the study is the technology of blood sausages with the addition of eggplant powder and green buckwheat.
In the process of modeling the recipe, eggplant powders for blood sausage were added in an amount of 5, 10, 15, 20 % by weight of unsalted raw materials. The optimum concentration was found to be 10 % powder.
It was determined that the introduction of plant additives into the stuffing increases the pH value from 6.35 in the control to 6.52 in the experimental sample of the finished sausage.
The introduction of the additive increases the moisture-retaining capacity of the stuffing proteins in the experimental samples by 6.28–6.87 % compared to the control.
The research found that the introduction of unconventional ingredients positively affects the changes in pH (norm 6.5–6.8), which during 5 days of storage was within 6.5–6.52. The control sample on the day of preparation had a pH of 6.5. During storage, the pH decreased dramatically, which indicates increased acidity, accordingly affects the quality of the finished product and confirms the short storage duration.
As a result of laboratory studies of microbiological safety indicators, only mesophilic aerobic and facultative anaerobic microorganisms were detected in the experimental samples, the number of which does not exceed the standards.
No ochratoxin A (OTA) was found in the studied blood sausage samples, indicating the safety of the developed product

Fruits and berries are an integral part of a healthy diet. The seasonality of production, short-term preservation in fresh form predetermines the need for their processing in order to provide the population with the necessary nutrients year-round.
Common sauces are tomato and mayonnaise sauces. The assortment of fruit sauces is limited, and the traditional technologies of their production do not make it possible to preserve the biologically active substances of vegetable raw materials in them as much as possible and do not always differ in high organoleptic indicators.
The established relationship between the quality of the fruit product, its color, nutritional value, and digestibility is directly dependent on polyphenols, which are chemically active and extremely unstable.
One of the adopted technological solutions aimed at preserving the polyphenols of cherries and black currants during the development of sauce technology is the use of aromatic plant raw materials widely distributed in Ukraine. Previous studies have suggested that the leaves of black currant, walnut, oregano, elderflower, and chamomile flowers are able to preserve polyphenols from oxidation.
Studies have confirmed the assumptions. It was established that the adopted concentrations of additives are optimal and make it possible to preserve cherry and blackcurrant bioflavonoids by 34...82 % more compared to traditional products. According to the organoleptic parameters, the products are advantageously distinguished by their intense color and pleasant aroma, characteristic of the raw materials.
The radioprotective properties of cherry and blackcurrant sauces were investigated. Their positive influence on the removal of radionuclides from the body has been proven. Sauces reliably have radioprotective, immunomodulating properties and can be used in therapeutic and preventive and baby nutrition

Projects in the field of information technology implemented on the basis of Scrum are quite often carried out under the influence of sharply changing circumstances both in the project itself and in the environment, which are characterized as risky. Therefore, the processes related to the situational project management, which is the object of this study, become important. For projects, it is necessary not only to identify the current situation but also to formally present it in order to evaluate and determine rational ways of achieving project goals under risky conditions, which is the task of this study.
Crisis situations in projects that arise under risky conditions are quite difficult to predict and take appropriate preventive measures in time. In difficult cases of establishing a cause-and-effect relationship between factors, we have unstructured data of various types and nature. Therefore, to solve this task, it is necessary to apply a combined approach, based on a complex combination of situational management methods, formalized, intelligent methods and expert methods, as well as ontological engineering. This will make it possible to build an adequate decision-making model under risky conditions, taking into account the influence of external and internal environmental factors.
An ontological model of situational project management based on Scrum is proposed, which will ensure the interconnection and consistency of decisions in accordance with the situation under risky conditions. The proposed model of the situation provides a formalized description and assessment of the situation under risky conditions in real time. The result of the application of this model is an increase in the efficiency of projects due to compliance with time limits, reduction of overspending of resources, as well as adaptation to rapidly changing circumstances and adequate response

Analysis of stress concentration in bone tissues and screw dental implants was per-formed on a model of screw join of the implant and surrounding bone tissues under the action of normal and tangential loads. The computations were performed by the bounda-ry element method for the plane strain state. It was assumed that those hollows in the spongy bone, which had formed in the bone after the implant insertion, are conformed to the screw thread on the implant. Bone tissues are considered as an isotropic and homo-geneous linear-elastic materials. It has been found that with the increasing in the spongy bone tissue elastic modulus, the maximum equivalent stresses in this bone tissue in-crease. Stresses in the cortical bone tissue decrease with the increasing in the spongy bone elastic modulus due to the decreasing in the load transferred to this bone part. Stresses in the spongy bone decrease with the increasing of the cortical bone layer elas-ticity modulus. The level of maximum stress in the cortical layer of the bone increases with the increasing of this bone tissue elastic modulus. The maximum of stresses in the cortical bone tissue are observed near the implant neck.

Nowadays there are different multiple modern technologies that allow studying cor-relates of development of sportsmen’s professional qualities. Eye tracking is one of such technologies, widely used in sport practice. The article demonstrates application of eye tracking to the task of testing wrestling athletes using a virtual environment demonstra-tion in a HTC Vive Pro Eye headset. Built-in eye-tracking systems of VR headsets often suffer from a low sampling rates and possible pupil loss during recording. Filtering can be applied in order to combat these effects, for example Kalman and similar filters. In this case, an adequate mathematical model in the state space is required. Usually a parametric or nonparametric model of the system in question is created. If dynamics of the model is known, the problem is usually reduced to identification of system parameters. It is not always possible to give an adequate mathematical description of the processes occur-ring in the system, or the system itself can be represented as a "black box". The oculomo-tor system may also be described as one such system. In such cases, nonparametric identification is applicable, that is, identification of the dynamics of the system. This pa-per proposes to identify the dynamics of the system using differential neural networks. They have good approximating capabilities for non-linear systems. The standard sig-moidal activation function was replaced by the Izhikevich activation function described by differential equations. The result of the work of the neural network identifier was an approximate system describing the dynamics of the ocular movement. Computational modeling was carried out. The workability of the model is studied on several data sets obtained by recording the oculomotor reaction of athletes-wrestlers to visual stimuli in a virtual environment, showing the effectiveness of the neural network learning laws.

An implant-supported prosthesis may have as few as three supporting implants, and the loss of one of them may lead to the loss of the entire structure. The framework of the Trefoil design is a standard bar made of high-strength titanium. Cyclic loading of metals and metal structures brings about the effect reducing the strength characteristics and known as fatigue. Fatigue limit is the value of stress below which the cyclic loading can-not destroy the structure. The aim of the work is to determine the treatment tactics for a patient having lost a distal implant and justify it according to the results of a three-dimensional finite element analysis of the effect of one dental implant loss on the biome-chanics of a mandibular implant-supported prosthesis with three supports. Bridge loading modeling was carried out with the Ansys 19.3 finite element analysis package and thus the stress-strain condition of the prosthesis and its components, im-plants and the frame itself, namely the bar, were determined. The stress values obtained allowed to draw the conclusion about the condition of metal structures under cyclic load-ing. The geometric model represents the mandible, including the compact and spongy bone layers, a bridge structure with two implants screwed into the spongy layer, and arti-ficial teeth attached to the implant structure. The model was created with the use of a real patient’s computerized cone-beam tomogram (CBCT) findings. The finite element model consists of 383507 second-order tetrahedral elements and 619339 nodes. The compo-nents are interconnected by contact elements of the "bonded" type, imitating a rigid con-nection without slipping. With 220 MPa being the fatigue limit for the loaded titanium implant construction, it was concluded that extended prosthesis construction can withstand an unlimited number of loading cycles at 100 N loading with the maximum stress of 154 MPa occurring in the left part of the jaw. The clinician’s tactics was determined for the potential loss of function or removal of one of the three Trefoil supporting implants: the prosthesis must not be removed until reimplantation.
