Authors: Sumiyana Sumiyana , Hendrian Hendrian , Effendi Ruslan , Fitrijati Krisnhoe , Sriwidharmanely Sriwidharmanely
Published: October 2021

This paper describes current research to drive future research challenges in accounting quality. The definition of accounting quality is mainly varying depending on the objective that the study pointed. Previous research revealed that many proxies describe the accounting quality but most of them from the financial perspective. Furthermore, this paper tries to expose this research issue in the behavioural approach and drive future research in the mixed method. It concludes that the behavioural issues can be a research model, triggering future research challenges in accounting quality. The authors support these triggers from the perspectives of political hegemony, bureaucracy ratcheting, cognitive distortion, and international accounting standard. Finally, we infer and simultaneously predict that accounting quality would broaden its concepts and lasting impression in the 21st century.

Authors: Chassagne Claire , Safar Zeinab , Deng Zhirui , He Qing , J. Manning Andrew
Published: October 2021

Modelling the flocculation of particles in a natural environment like an estuary is a challenging task owing to the complex particle-particle and particle-hydrodynamic interactions involved. In this chapter a summary is given of recent laboratory and in-situ studies regarding flocculation. A flocculation model is presented and the way to implement it in an existing sediment transport model is discussed. The model ought to be parametrized, which can be done by performing laboratory experiments which are reviewed. It is found, both from laboratory and in-situ studies, that flocculation between mineral sediment and organic matter is the dominant form of flocculation in estuarine systems. Mineral sediment in the water column is < 20 μm in size and its settling velocity is in the range [0–0.5] mm/s. Flocs can then be categorized in two types: flocs of size [20–200] μm and flocs of size > 200 μm. The origin of these two types is discussed. The two types of flocs are found at different positions in the water column and both have settling velocities in the range [0.5–10] mm/s.

Authors: Zhang YanQing , E. West Neil
Published: October 2021

The study cases in western Utah of the United States and Yukon Territory of Canada have more natural land and conservative ecosystems in North America. The ecosystem classification of land (ECL) in these two ecoregions had been analyzed and validated through implementation. A full ECL case study was accomplished and examined with eight upper levels of ECOMAP plus ecological site and vegetation stand in Western Utah, the US. Theoretically, applying Köppen climate system classification, Bailey’s Domain and Division were applied to the United States, North America, and world continents. However, Canada’s continental upper level ecoregion framework defined the ecological Mozaic on a sub-continental scale, representing an area of the hierarchical ecological units characterized by interactive and adjusting abiotic and biotic factors. Using Bailey’s Domain as the top level of Canada’s territorial ecoregion was recommended. Eight levels of ELCs were established for Yukon Territory, Canada. Thus, the second study case recommends integrating the ecosystem approaches with Bailey’s upper level ECL, broad ecosystem classification, and objectively defined ecological site in different countries, or ecoregions. Our study cases had exemplified the implementations with a full ELCs in Bailey’s 300 Dry Domain and 100 Polar Domain.

Published: October 2021

The structural, magnetic, electronic and elastic properties of A15 X3Ru (X = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn) binary alloys are investigated using first-principles density functional theory (DFT) methods. Ru-based alloys have attracted remarkable research interest due to their unique properties, which make them suitable for high-temperature structural applications. In this chapter, the properties of several A15 Ru-based alloys are investigated in order to select the best suitable alloy/s for aerospace application. Heats of formation are calculated to determine the thermodynamic stability of the materials. Knowledge of the values of elastic constants is essential for understanding the mechanical properties of the materials. From our calculated elastic constants, the bulk modulus, shear modulus, Young’s modulus, Poisson’s ratio, melting temperature, anisotropic factor and the ratio B/G are determined. The electronic density of states are calculated and discussed. Lastly, the magnetic properties of A15 X3Ru alloys are studied. Thermodynamically stable Mn3Ru possesses high-magnetic moment compared to other X3Ru alloys, these results could pave way to experimental realization (synthesis) of Mn3Ru material.

Authors: Alves Grubertt Guilherme , Serassuelo Junior Helio
Published: October 2021

Some surveys have pointed out that only a portion of young people practice sports with some regularity, and that of those who start sport practice, there is a high rate of abandonment. In this sense, experts indicate that understanding the motives that lead to sport practice could be an important way to understand this phenomenon, especially for young ages. The expectation is that this publication can provide important information on motivational indicators related to sports practice in young ages, which may contribute significantly to the expansion of new knowledge in the area, offering a new option to aid future studies on the theme, in addition to assisting in intervention actions in the school context and in the scope of exercise and sport. Thus, the present chapter aims to present conceptual approaches that support research involving sports practice motivation in young ages. In addition, the study brings data from one of the largest investigations of sport practice motives of Brazilian pupil-athletes.

Authors: Yang JiuJie , P.L. Ng Jerome , Zhang Kaixi , Liu Liang , Kam Wai Wong Vincent
Published: October 2021

Rheumatoid arthritis (RA) being a chronic inflammatory disease can be affected by both genetic and environmental factors. Abnormal functioning of immune response is the main underlying cause of RA. A growing number of studies on related diseases uncovered that microRNA (miRNA) may influence the pathogenesis of RA, such as the promotion of proliferation of fibroblast-like synoviocytes and secretion of cytokines by highly expressed miRNAs. A large number of studies have reported the aberrant expressions of miRNAs during the entire phase of RA, from the preclinical to terminal stages. These dynamic changes can be potentially developed as a bio-marker for predicting the risk, diagnosis and clinical management of RA. This chapter aims to summarize and discuss miRNAs’ roles and mechanisms in the process of RA development, differential diagnosis from other diseases, clinical management and refractory RA. Therefore, miRNA demonstrates future perspectives of diagnosis and treatment of clinical RA under the support of newly discovered theoretical basis.

Authors: Orain Porter Roy
Published: October 2021

The supplementation of baked foods, namely cookie/biscuits, bread and cakes with agricultural by-products from cereal based fibres (rice bran and corn fibre) and sugarcane bagasse at rates of 0% - 15%; 0% - 30% and 0% - 10% respectively can significantly improve its nutritive value and enhanced its physical and sensorial qualities. This chapter aims to review the role of dietary fibres derived from selected cereals (rice bran and corn fibre) and sugarcane bagasse in baked foods, namely cookies/biscuits, bread and cakes; evaluate their effects on the physical and sensory qualities of these baked food products and to critically assess their beneficial impacts in baked foods. These enriched food products can potentially be utilised in shaping health policies, contribute to the dietary fibre needs of consumers and facilitate the development of functional foods. Fibre enriched foods potentially can assist in improving various physiological functions of the human body. A Keyword-based search strategy was utilised to conduct a comprehensive search for articles catalogued in ScienceDirect, Web of Science, PubMed, Medline, CINAHL and Google Scholar that were published between January 1, 2010 and August 1, 2020. Applicable aspects of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines provided the framework of this review. Fourteen (14) studies met the inclusion/extraction criteria and was placed into sub-groups by food types and fibre used in supplementation. Only eleven (11) studies were suitable for statistical data analysis. The supplementation of sugarcane bagasse at both 5% and 10% and rice bran up to 15% into cookies/biscuits significantly undesirable acceptance (p < 0.05). Corn fibre enriched cookies/biscuits up to 20% showed a significantly (p < 0.05) favourable impact on the sensory qualities of the food product. The physical qualities of sugarcane bagasse supplemented cookies/biscuits were negatively affected. The incremental addition of sugarcane bagasse resulted in at 50% rise in the firmness of 10% enriched cookies/biscuits, from 5.7 ± 5.4 (Kg Force) to 13.0 ± 3.9 (Kg Force). Corn fibre cookies supplementation did not significantly affect its physical qualities. Rice bran incorporation of 15% in bread showed a significant (p < 0.05) undesirable effect on its sensory qualities. However, the was no significant adverse effect on its physical quality.

Published: October 2021

Severe acute respiratory syndrome (SARS) is the leading cause of death in COVID-19 infection, however, multi-organ dysfunction due to COVID-19 and/or because of co-morbidities is a usual accompaniment causing unfavorable outcome. Early detection of organ failure and giving appropriate organ support may improve the chances of survival. Arterial Blood Gas (ABG) analysis; electrolytes coupled with clinical picture and with organ related laboratory investigations may help in diagnosis of MODS and sepsis in COVID-19 SEVERE SYNDROME. Acute kidney injury (AKI), myocarditis, thromboembolism, acute liver de-compensation, hospital acquired infections, cardiac arrest, glycemic variability, thyroid dysfunction and other organ failure may lead to MODS. As patients having multiple organ syndrome requires ICU admission and interventions like intubation, hemodialysis and other extracorporeal treatment support knowing holistically about “COVID-19 MODS” is important for treating physicians.

Authors: Naveed Safila , Sadia Halima
Published: October 2021

Angiotensin converting enzyme (ACE)-inhibitors are effective in patients with mild to moderately severe hypertension, collagen vascular and cardiovascular disease. They are also used in the prevention and treatment of myocardial infarction and in the management of cardiac arrhythmias. Patients with cardiovascular diseases are generally on multiple medicines that’s why it is imperative to study drug–drug interactions of medicines which are commonly taken together in any given case, as combined administration of different medicines can significantly influence the availability of drugs. In the present study we investigated the “in vitro” interactions of ACE inhibitors (enalapril, captopril and lisinopril) with frequently prescribed and co-administered drugs in simulated human body environments. These interactions were monitored by means of UV spectrophotometry and separation technique as RP-HPLC. Prior to start of actual drug interactions, the method of analysis of each drug was established and its various parameters validated for considering its use in testing of drug in vitro as well as in human serum. For this purpose, an attempt was made to develop a number of new HPLC methods for determination of ACE inhibitors (enalapril, captopril and lisinopril) and simultaneously with interacting drugs. These methods were optimized, validated and then successfully employed for the quantitation of enalapril, captopril and lisinopril and selected drugs in interactions studies. As a result, new methods for the quantitation of individual as well as multiple drugs were developed. The interacting drugs selected were antidiabetic drugs (metformin, glibenclamide, glimepride and pioglitazone. Interaction consequences revealed that the availability of enalapril was not affected in presence of antidiabetic drugss whereas the availability of captopril and lisinopril were altered in presence of NIDDMs.
Perspective Chapter: Cultivating Environments of Belonging in Psychiatry, Clinical Psychology and the Allied Mental Health Fields
Authors: Lazaridou Felicia , Heinz Andreas
Published: October 2021

Mental health science as a field of research, education and care practices has a fundamental role to play in mitigating the costs of racism for affected communities. The development and the implementation of solutions, such as gaining perspective, encouraging mentorship and finding empowerment, can only meaningfully occur through the involvement of lived experience expertise. Notably, as a first step, the inclusion of such expertise at a structural level would require the cultivation of environments of belonging in psychiatry, clinical psychology and the allied mental health fields for students racialised as Black and Of Colour. Black Lives Matter, as a specific political movement, articulates a critique of how certain subjectivities and identities belong more naturally in spaces of knowledge and power such as universities. This chapter reflects on belonging as a ‘feeling of mattering’ and a contemporary politics. It is argued that the possibility to facilitate the effective elimination of structural racism in mental health science requires the cultivation of environments of belonging at an institutional level causing greater inclusivity and enjoyment for Black students and students Of Colour in ‘liberated learning spaces’. A clear, actionable path to create environments of belonging to help resolve structural racism is outlined.

Therefore, it's recommended to medical staff for delivering pre-surgery electronic educational interventions for LC surgical patients in order to reduce the level of preoperative anxiety.
The beginning of women's emancipation in Sephardic communities on the territory of today's Serbia
Authors: Vidosavljević Milena
Published: October 2021

After the exile from Spain in the 15th century, the Sephardim set out to seek refuge in other countries. That is how they came to the Balkans and built more communities on the territory of today's Serbia. In order to adapt and cooperate with the local population, the Sephardim were active in the public sphere, being educated and learning the Serbian language. On the other hand, the female part of the Sephardic population was for many years exclusively related to the household and the family. Over time, women gained more rights and opportunities for emancipation and education, and the Sephardic women began to change their previous social role. In this regard, the aim of the paper is to present a brief overview of the arrival of Sephardim in today's Serbia, to present some of the Sephardic communities, and then to draw attention to the position, role and education of Sephardic women, Women's Jewish Society and how were emancipated Sephardic women in Belgrade, Novi Sad, Nis and Pirot.
Kaza Mitrovica 1889-1900
Authors: Zarković Vesna
Published: October 2021

Kaza Mitrovica was part of the Priština Sandžak of the Kosovo vilayet until its liberation in the First Balkan War. Period from the opening of the consulate of the Kingdom of Serbia in Priština in 1889 until 1900 was marked by numerous murders and oppressions throughout Old Serbia, which did not skip Mitrovica. This situation deviated from the position of the city, which was located at the crossroads and at the end of the railway, whose starting point was Thessaloniki. In addition, Mitrovica was connected by road to neighboring towns, Novi Pazar, Peć and Priština, via Vučitrn. Thanks to that, it developed rapidly, the influx of inhabitants was higher and it represented the center of the northwestern part of the province of Kosovo. The newly arrived population in Mitrovica consisted of muhajirs fleeing Bosnia and Serbia, as well as Serbs who came from Metohija and other parts of Old Serbia due to violence. Also, numerous craftsmen and merchants settled in search of work and a better life. The city was the seat of a strong military garrison of the Turkish army, which did not react to prevent the tyranny of the Arbanas. On the contrary, the representatives of the civil and military authorities, in order to maintain an apparent peace, often negotiated with the greatest oppressors among the Arbanas. The relationship between the authorities and the villains was reflected on the Serb population of Mitrovica, which was exposed to various atrocities. The only help was provided by the consulate of the Kingdom of Serbia in Priština, while the representatives of the authorities, from local to district, usually remained silent. This attitude of the Turkish authorities towards the crimes led to general insecurity and unrest among Serbs, who emigrated in large numbers to Serbia.
Computational Simulations of Wide-Beam Air-Cavity Hull in Waves
Authors: Matveev Konstantin I.
Published: October 2021

An effective method to reduce ship drag is to supply air under specially profiled bottom with the purpose to decrease wetted surface area of the hull and thus its water resistance. Although such systems have been installed on some vessels, the broad implementation of this technique has not yet occurred. A major problem is how to sustain air lubrication in rough water. Modeling of air-ventilated flows is challenging, but modern computational fluid dynamics tools can provide valuable insight. In this study, a wide-beam, shallow-draft hull with a bottom air cavity is considered. This hull imitates a semi-planing boat that can be used for fast transportation of cargo from large marine vessels to shallow shores. To simulate fluid flow around this hull in calm water and head waves, as well as heave and pitch motions of the boat, CFD software Star-CCM+ has been employed. It is found that the air cavity effectiveness decreases in waves; vertical accelerations exhibit high-frequency oscillations; and heave, pitch and vertical accelerations increase, while time-averaged heave, pitch and added drag show non-monotonic behavior with increasing wave amplitude. The air-cavity hull also demonstrates substantially lower vertical accelerations in waves in comparison with a similar solid hull without bottom recess. Time histories of kinematic parameters and distributions of flow field variables presented in this paper can be insightful for developers of air-cavity hulls.
Modeling Vertical Planing Boat Motions using a Neural-Corrector Method
Authors: Marlantes Kyle E. , Maki Kevin J.
Published: October 2021

The dynamics of high-speed planing craft are complex and nonlinear. Standard analysis methods, such as linear potential theory, while convenient and computationally efficient, are often not suitable for use in predicting the dynamics of such craft because physical realities or design requirements invalidate the inherent assumptions. High-fidelity methods, such as state-of-the-art CFD simulations, can offer accurate solutions, but these methods are limited by computational cost and numerical sensitivity. In addition, these methods are not efficient enough to provide rapid evaluation of operability, i.e. simulations over a wide range of operating conditions and environments. This leaves few practical analysis options for small, high-speed craft designers who need to perform such predictions. In this paper, the authors present a neural-corrector method that shows promise in providing efficient predictions of vertical planing craft motions. The method retains higher-order terms typically truncated in the classical coupled 2-DOF system of ordinary differential equations using Long Short-Term Memory (LSTM) recurrent neural networks. In this manner, the robust solution provided by the linear model is retained, and the LSTM networks act as higher-order correctors. The correctors primarily regress on the solution, affording familiar numerical integration techniques for systems of nonlinear differential equations. Training and validation results from the method are compared to nonlinear simulations of 2-DOF motion of a Generic Prismatic Planing Hull (GPPH) at forward speed in head seas, with time histories given for both regular and irregular waves.
Control Oriented Maneuver Model of Prismatic Planing Hull
Authors: Sung Li P. , Fabien Brian
Published: October 2021

Roll yaw coupled dynamics are not well characterized and existing low cost models are limited in range of applicability. We utilize an interpolation based approach to address a wider range of conditions with reduced computational requirements. By interpolating test data to estimate hydrodynamic forces and empirically modeling roll damping and added mass, we establish a 4DOF maneuvering model for prismatic planing hulls in calm water. It is validated against relevant tests and show significant computational resource savings in comparison with potential flow based methods. Simulation of an extreme turning maneuver and an asymmetrical loading case demonstrates its potential for use in initial design, control and evaluation.

Long-Life Coatings for Offshore Structures
Authors: Darden Winn
Published: October 2021

Coatings are used on offshore steel structures to prevent corrosion and to preserve their appearance. Conventional coating systems require repainting after only 10-15 years. Fluoropolymer coatings have been used on offshore structures since the mid-1980’s. These coatings offer excellent corrosion protection as well as good gloss and color retention for more than 30 years in some cases. Using fluorinated coating systems can substantially lower life cycle coating costs and require fewer maintenance cycles than conventional coatings.
Applied Data Analytics to Buoy Records for Weather Window Evaluation
Authors: Bhaumik Tirtharaj , Basu Shiladitya
Published: October 2021

This paper analyzes weather data recorded by typical oceanographic buoys using data analytics and regression techniques. Time series data over a period of more than four decades (1976 – 2020) are reviewed and profiled. A set of key variables including seasonality, wind speed, wind direction, wave period, wave direction, etc., are screened from the buoy measurements to build a predictive model based on multiple linear regression for significant wave height prediction. A sensitivity analysis is then conducted for the available weather window corresponding to specified threshold operational limits of the significant wave height. Key insights are presented along with suggestions for future work to assist marine operators in planning and derisking offshore operations. Utilizing the algorithms and workflows presented in this paper, a user can increase confidence in weather window prediction, and develop safer, efficient offshore operation plans.
Assessment of Alternative Fuels and Engine Technologies to Reduce GHG
Authors: Lindstad Elizabeth , Gamlem Gunnar , Rialland Agathe , Valland Anders
Published: October 2021

Current greenhouse gas emissions (GHG) from maritime transport represent around 3% of global anthropogenic GHG emissions. These emissions will have to be cut at least in half by 2050 compared to 2008 as adopted by IMO´s initial GHG-strategy to be consistent with Paris agreement goals. Basically, the required GHG emissions reduction can be achieved through: Design and other technical improvement of ships; Operational Improvement; Fuels with zero or lower GHG footprint; or a combination of these. Where fuels with zero or lower GHG footprints often are perceived to be the most promising measure. The motivation for this study has therefore been to investigate these alternative fuels with focus on their feasibility, energy utilization and cost in addition to their GHG reduction potential. The results indicate: First, that fuels with zero or very low GHG emissions will be costly; Second, that these fuels might double or triple the maritime sector's energy consumption in a Well-to-Wake context; Third, if large amounts of renewable electricity becomes available at very low prices, synthetic E-fuels such as E-diesel and E-LNG which can be blended with conventional fuels and used on conventional vessels, will be more commercially attractive than hydrogen and ammonia.

Aim. To analyse effectiveness of introduced genes of ornithine-δ-aminotransferase  (oat) Medicago  truncatula and fragments of two copies of first exon and intron of the gene prolinedehydrogenase (pdh) of Arabidopsis thaliana, that form double stranded RNA suppressor of gene  of the prolinedehydrogenase wheat, in the increase of her productivity for the actions ofosmotic stress. Methods. Determination of the content of free L-proline (Pro); of the activity of the enzyme ornithine-δ-aminotransferase (OAT), the activity of proline dehydrogenase (PDG), indicators of crop structure. Results.  It was found that wheat plants with an additional copy of the oat gene are characterized by increased OAT activity, which is not reflected in the Pro content. Analysis of plants with integrated elements that form a double-stranded RNA suppressor of the pdh gene found a decrease in PDG activity and an increase in Pro content. It was found that T2 generation of biotechnological plants UK 322/17 with suppressor of the pdh gene and UK 95/17 with an additional copy of the oat gene, in drought conditions were characterized by higher rates for a number of crop elements compared to their original forms. Conclusions. Increased expression of the oat gene leads to improved wheat growth, which has a positive effect on plant productivity in conditions of water deficiency.  Partial suppression of the proline dehydrogenase gene causes improved performance due to the increased content of free proline during drought.

Aim. Optimization of conditions and genetic transformation of new promising genotypes of winter bread wheat (Triticum aestivum L.) by in planta method. Methods. Agrobacterium-mediated transformation by the in planta method using strain AGL0 and vector construct pBi-OAT. Results. The influence of air temperature, optical density of cells of agrobacterial suspension, inoculation day and composition of inoculation medium on the frequency of obtaining transgenic plants of new promising genotypes of winter wheat was studied. The dependence of the frequency of obtaining transgenic plants on environmental conditions, in particular temperature, has been established. It was found that the temperature regime of 20-22 °C provided the largest number (4.4%) of wheat transformants, and when the temperature is reduced to 16-18 °C there is a decrease in the efficiency of T-DNA transfer into the plant genome and the lowest frequency of transformation is observed. Conclusions. The largest number of transformants was obtained using a inoculation medium without sucrose, the optical density of cells of the agrobacterial suspension of 0.4 op.od. and inoculation on the third day after castration of ears.

Keywords: Triticum aestivum L., Agrobacterium-mediated transformation, ornithine-δ-aminotransferase gene.

Aim. The investigation of the influence of the constituents of Izatison, DMSO and PEG400, on the oat growth and its grain productivity during 2 generations after the seed treatment became the aim of this study for the elucidation of mechanism of Izatison stimulant influence. Methods. The broad scale of the concentrations of the solvents composition in the proportion, to be as in Izatison, was used. The plants were grown in the field. The growth processes were evaluated by the stem height on the tubing stage. The grain productivity was characterized by the panicle length, the grains number in the panicle and of theirs weight. Results. The dependence of influence of the solvents composition on the stem growth from its concentration was detected in the first generation. In some variants the negative influence was revealed on the grains number in the panicle and on theirs weight. The stimulation of the growth regardless from the solvents concentration was observed in the second generation and the more pronounced negative effect on the grain productivity. Conclusions. The solvents DMSO and PEG400 are able to influence on the oat growth and its productivity, and that effect was manifested also in 2 generation after the seed treatment.

Keywords: Izatison, DMSO, PEG400, oat growth and grain productivity.

Aim. assessment  of  accessions from the lentil national collectionon the level of drought resistance on a PEG-6000 solution. Methods. The germination was carried out in growth plates on a filter paper bed at t = 21ºC for five days. A working solution of PEG-6000 with concentrations of 15.0% and 19.5% was used. The control was germinated in distilled water. The length of the shoot and root was measured and the level of depression of growth processes was calculated. Results. When germinating on a PEG-6000 solution with 19.5% concentration, the overwhelming number of accessions had depression indicators for shoots above 85% and above 60% for roots, and therefore it was not possible to isolate samples tolerant to the action of PEG-6000. When germinating on a 15%  solution of PEG-6000, a wider range of variation was noted: depression in feature of “root length” ranged from 0% to 100%, “shoot length” - from 50% to 100%. The calculated Spearman's rank correlation coefficient confirms that shoots, in comparison with roots, are more sensitive to the action of osmotic in both variants of the experiment. Conclusions. The concentration of PEG-6000 was established for the selection of sources and the ranking of samples by drought resistance. Sources of drought resistance were identified from the studied sample – accessions subsp. microsperma: 8-MIL M 5 (UD0600007, France), UD0600028 (Ethiopia), Giza 9 (UD0600065, Egypt) and the accession-standard of drought resistance is Gornostepnaya (UD0600131, Armenia) subsp. microsperma.

Aim. The aim of this study was to analyze grain quality indices in winter common wheat lines with introgressions of chromosome 1U from Aegilops biuncialis Vis. marked by storage protein loci. Methods. Acid polyacrylamide gel electrophoresis and SDS-electrophoresis of storage proteins were performed to identify introgressions. Grain quality indices (SDS sedimentation volume and grain protein content) were analyzed in lines with introgressed chromosome 1U or its arm 1UL, as well as in the cultivars Panna and Bezostaya 1. Results. SDS-sedimentation volume in the cultivars and lines depended on year’s conditions. The studying of the lines during two years has demonstrated that the presence of the allele at the high molecular weight glutenin subunit locus Glu-U1 from Ae. biuncialis was associated with a high volume of SDS-sedimentation SDS30 (higher than that in the cultivar Bezostaya 1). The introgressive lines show high grain protein content. Conclusions. The effect of the allele at the high molecular weight glutenin subunit locus Glu-U1 from Ae. biuncialis on SDS-sedimentation value is similar to that of the high-quality allele Glu-B1al. The lines with the introgressed allele at Glu-U1 from Ae. biuncialis are valuable initial material for breeding for quality.Keywords: Triticum aestivum, Aegilops biuncialis, high molecular weight glutenin subunits, SDS-sedimentation, protein content.

Aim. Despite numerous scientific studies of possible causes of miscarriage, their etiology remains unclear in approximately 50% of cases. Investigate the prevalence of thrombophilia associated gene polymorphism FGB 455G/A, FII 20210 G/A, FV 1691G/A, ITGA2 807C/T, PAI-1 5G/4G and MTHFR 677C/T in women with sporadic and recurrent miscarriages. Methods. Group I included 35 women with sporadic miscarriage (SM), group II consisted of 57 women with recurrent miscarriage (RM) and 55 women of control group. Genetic testing was performed by PCR-RFLP. Results. In group I of women with SM the 455GA genotype of the FGB gene was more common and its presence in the genotype increases the risk of SM by 4 times and the presence of the 455A allele by 2 times. The Leiden mutation increases the risk of SM by 5 times. In II group of women with RM, the frequency of the 455 AA genotype of the FGB gene was more prevalent and the risk of RM was increased 2.5 times. It is shown that the risk of RM increases 4 times in the presence of the Leiden mutation. The 4G allele of the PAI-1 5G/4G polymorphism leads to a 2-fold increase in the risk of RM, and the presence of the 677TT genotype of the MTHFR gene increases the risk of RM by 3 times. Conclusions. Genetic factors of inherited thrombophilia alleles 455A of the FGB gene, 1691A of the FV gene, 4G of the PAI-1 gene and 677T of the MTHFR gene are alleles of significant risk of reproductive losses both sporadic and, to a greater extent, recurrent.
