Published: May 2024

Graphical abstract

Endometriosis is a chronic inflammatory condition affecting one in ten women and those assigned female at birth, defined by the presence of endometrial-like tissue outside the uterus. It is commonly associated with pain, infertility, and mood disorders, and is often comorbid with other chronic pain conditions, such as irritable bowel syndrome. Recent research has identified a key role for the microbiota–gut–brain axis in health and a range of inflammatory and neurological disorders, prompting an exploration of its potential mechanistic role in endometriosis. Increased awareness of the impact of the gut microbiota within the patient community, combined with the often-detrimental side effects of current therapies, has motivated many to utilise self-management strategies, such as dietary modification and supplements, despite a lack of robust clinical evidence. Current research has characterised the gut microbiota in endometriosis patients and animal models. However, small cohorts and differing methodology have resulted in little consensus on the data. In this narrative review, we summarise research studies that have investigated the role of gut microbiota and their metabolic products in the development and progression of endometriosis lesions, before summarising insights from research into co-morbid conditions and discussing the reported impact of self-management strategies on symptoms of endometriosis. Finally, we suggest ways in which this promising field of research could be expanded to explore the role of specific bacteria, improve access to ‘microbial’ phenotyping, and develop personalised patient advice for reduction of symptoms such as chronic pain and bloating.

Lay Summary

Endometriosis is a chronic condition affecting one in ten women and those assigned female at birth, defined by the presence of tissue, similar to the womb lining, growing outside the womb. Symptoms include pelvic pain, period pain, pain during sex and when going to the toilet, digestive disturbance and bloating, infertility, depression, and anxiety. Standard treatments, including surgery and hormone-altering drugs, often have negative side effects. Many women with endometriosis use self-management strategies to control their symptoms, including changing their diet or taking supplements. Although some reports suggest such strategies are helpful, there is limited high-quality evidence to support their use. Here, we discuss how dietary adaptations could be impacting endometriosis-associated symptoms via changes to the bacteria within the gut. Gut bacteria communicate with the brain and influence inflammation throughout the body. Therefore, altering the gut bacteria through dietary changes can potentially benefit a variety of endometriosis-associated symptoms.

Let $L^2((0;1);x^4 dx)$ be the weighted Lebesgue space of all measurable functions $f:(0;1)\rightarrow\mathbb C$, satisfying $\int_{0}^1 t^4 |f(t)|^2\, dt<+\infty$. Let $J_{-5/2}$ be the Bessel function of the first kind of index $-5/2$ and $(\rho_k)_{k\in\mathbb N}$ be a sequence of distinct nonzero complex numbers. Necessary and sufficient conditions for the completeness of the system $\big\{\rho_k^2\sqrt{x\rho_k}J_{-5/2}(x\rho_k):k\in\mathbb N\big\}$ in the space $L^2((0;1);x^4 dx)$ are found in terms of an entire function with the set of zeros coinciding with the sequence $(\rho_k)_{k\in\mathbb N}$. In this case, we study an integral representation of some class $E_{4,+}$ of even entire functions of exponential type $\sigma\le 1$. This complements similar results on approximation properties of the systems of Bessel functions of negative half-integer index less than $-1$, due to B. Vynnyts'kyi, V. Dilnyi, O.

Authors: Kumar Shailendra , Parihar Suman , Srivastava Priyanka , Kumar Ashok
Published: May 2024

Two progenies of Melia dubia plantation of six year old were selected for studies on physical and anatomical properties of wood. Data for each selected trees progenies selected were recorded for height, clear bole length, diameter at breast height, initial moisture content, specific gravity and sapwood proportion. Macroscopic features were observed and recorded under 10 x lenses. Slides were prepared for microscopic views of the wood in three directions viz. pith, middle and periphery. Maceration was done as per Schultze's method to prepare slides for studies on fiber and vessel morphology of the wood samples. The analysis revealed that wood of M. dubia showed distinct growth rings, the sapwood was yellowish white in colour, the heartwood was yellowish brown in colour. The mean moisture content in the living trees was recorded to be 80.3%. The specific gravities of selected progenies were 0.43 and 0.35. The difference in specific gravities between the progenies was statistically significant. Mean sapwood % in both the progenies was 39.12 %. While the mean fiber length was 716.72µm, mean fiber wall thickness was 4.15µm. Mean vessel length of the progenies was 260.5 µm. Significant variability in physical and mechanical properties of wood, indicates a need of careful tree breeding programme for the species.

Authors: JI Amonum , G Dachung , OS Tsa
Published: May 2024

Germination and early growth of Jatropha curcas from different seed sources in Benue State were assessed over a period of ten weeks. Jatropha curcas L. is a tropical species from the family Euphobiaceae. Special interest has been shown in the cultivation of the species for oil extraction, especially since it is drought resistant and can be cultivated on marginal land, without competing with food crops. The ripe fruits of Jatropha curcas were collected from the ground; and directly on mother trees from distinct sources (provenance) (Ukum, Makurdi and Otukpo) areas in Benue, Nigeria. Benue state was stratified into three ecological zones; and each source (provenance) was purposively selected from each zone as a result of seeds availability. Fifty seeds where collected from each of the three sources; making a total of 150 seeds planted for this study. The data collected were based on germination rate, seedlings girth, number of leaves, height, and leaf area. The data collected were analysed using descriptive statistic. The results of the germination indicated that for the first 5 days there was no germination. The seeds sourced from Otukpo had the best growth performance in terms of seedling height (15.25cm), leaf number (4.39), girth (0.8cm), leaf area (62.63cm2). While seeds sourced from Makurdi had the least growth performance. Thus, it is recommended that J. curcas plantation can be established in the study area, using seeds sourced from Otukpo.

Published: May 2024

Law Number 28 of 2007 and Government Regulation Number 31 of 2012 mandate the provision of tax data by government agencies, institutions, associations and other parties (ILAP) to the Directorate General of Taxes (DJP). Even though criminal sanctions have been regulated, the implementation of these obligations is not optimal. DJP adopted alternative methods, such as a Memorandum of Understanding/MoU, to obtain tax data from ILAP. This research uses a research method that focuses on positive law with the theory of legal certainty by Gustav Radbruch, the theory of authority by Max Weber, and the theory of taxation by Adam Smith. The results of the research show that there is a discrepancy in the implementation of the obligation to submit tax data with positive law and the theory of legal certainty. Steps are needed to create a Memorandum of Understanding/Agreement/MoU up to a Cooperation Agreement by the DJP with ILAP to make the obligation to submit tax data and information from ILAP run smoothly in accordance with the study. theory of authority by Max Weber. To realize legal certainty in these regulations and to increase state revenues in accordance with the study of tax theory by Adam Smith, it is recommended that there be changes to norms in Law Number 28 of 2007 by adding an article regarding the making of a Memorandum of Understanding/MoU/Cooperation Agreement to increase legal certainty. and contribution to state revenue.Keywords: Reconstruction of Obligations; Data Submission; Tax Information; Legal certainty

Authors: Gilpin Thomas R , Maznyczka Annette , Anantharam Brijesh , Dana Ali
Published: May 2024

Background: Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has evolved a great deal over recent years, with increased procedural success and lower complication rates being reported. This study aims to evaluate the feasibility, safety and success of a dedicated CTO programme in a large UK PCI centre without on-site cardiothoracic surgery facilities. Methods: Clinical and procedural data were retrospectively collected for consecutive unselected patients undergoing CTO PCI between 2015 and 2019 from the local database and regional electronic patient records. In-hospital outcomes and long-term major adverse cardiovascular events (all-cause mortality, MI, stroke and target vessel revascularisation) were recorded. Results: A total of 170 patients underwent 191 CTO procedures during the study period. The mean age was 63 ± 10 years and 80.6% of patients were male (n=137). The clinical indications were: stable chronic coronary syndromes in 88.5% (n=169) of patients; staged procedures in the context of acute coronary syndromes in 1.6% (n=3); and presentation with acute coronary syndrome in 9.9% (n=19). The procedural success rate was 50.0% (n=25) for general interventional cardiologists and 90.1% (n=127) for dedicated CTO operators. In-hospital major adverse cardiovascular events occurred once (0.5%) and interhospital transfer for emergency salvage cardiac surgery was not required. Long-term follow-up data at a median duration of 3.8 years revealed 4 (2.4%) cardiac deaths, 14 (8.3%) spontaneous MI events and 10 (5.9%) target vessel revascularisations. Conclusion: These data suggest CTO PCI using contemporary techniques is both safe and effective when undertaken in a high-volume non-surgical centre by experienced operators.

Improving the productivity of poultry, especially egg crosses, depends on the quality of the bioceramic calcite (CaCO3) layers and surface glycoprotein film of the egg (cuticle). These are the barriers that control the flow of gases and water vapor. Any disruptions in the transport process can lead to a significant reduction in egg hatchability. It has been proven that treatment of chicken and turkey eggs with acid solutions (acetic acid or hydrochloric acid) and sodium hypochlorite prior to hatching has increased egg hatchability compared to the control. In view of this, the aim of this study was to investigate the protective structures of incubation eggs of chickens and turkeys using non-destructive electron microscopic methods and computer processing of digital images of the cuticle coatings of these eggs for reliable prediction of the degree of increase in gas permeability of the cuticle-shell system due to the destructive effect of various chemicals, including disinfectants, for pre-hatching egg treatment. In the experiments, hatching eggs of Leghorn White hens (n = 90) 15–20 weeks of laying and Broad Breasted White turkeys (n = 80) were used. The antimicrobial agents used in the experiments were a 0.6% solution (0.08 mol/L) of sodium hypochlorite, a 2.5% solution (0.4 mol/L) of acetic acid, and a 5.0% solution (1.40 mol/L) of hydrochloric acid. Using the computer analysis of digital electron microscopic images of the egg surface with the software packages Visilog and FemtoScan Online, it was experimentally proved that the destructive effect of these substances on the cuticle-shell system increases in the range of sodium hypochlorite < hydrochloric acid < acetic acid, which positively correlates with the gas permeability of hatching eggs of chickens and turkeys and the egg hatchability index. The presence of fundamentally different morphological features and correlations of the cuticle of chicken and turkey eggs in response to the action of acids and oxidants used for pre-hatching treatment was shown. The digital markers of the cuticle-shell system state, obtained from analytical programs of digital images, have been established, which makes it possible to reliably predict the indicators of increasing the hatchability of chicken and turkey eggs under the conditions of using certain chemicals. The prospect of further research is to study the effect of modern complex antimicrobial agents on the hatchability of poultry eggs of different species.

The issue of stress and behavioral disorders are growing significantly in the contemporary word in humans and animals alike. Various drugs are used to modify affected behavior, including psychotropic, anticonvulsant, antihistamines, hormones, analgesics, and neuroleptics. Psychotropic drugs are prescribed for animals with behavioral disorders, signs of anxiety or hypersensitivity. Improving the methods of diagnosing and treating behavioral disorders in animals can enhance animal welfare and optimize animal husbandry technology. Future research should be aimed at improving and optimizing the use of psychotropic drugs for behavioral disorders of various animal species. The main indication for the use of anxiolytic drugs is behavioral disorders associated with anxiety in wild and domestic animals. When anxiolytic drugs are used in mammals their pharmacological properties, the dependence of their action on the route of administration, age and species of the animal, and the ability to selectively affect the central nervous system should be taken into account. The most commonly used drugs for the treatment of behavioral disorders in animals are fluoxetine, amitriptyline, escitalopram, haloperidol, zuclopentixol and azaperone. Fluoxetine is an effective drug for the treatment of dogs with behavioral disorders associated with psychological changes. An important component of escitalopram's pharmacological effect is the psychomotor influence, when the animal's behavior changes are due to improved motor activity. Zuclopentixol has a wide range of anxiolytic, sedative and analgesic effects when used in wild cloven-hoofed animals. Amitriptyline along with antidepressant properties, has a local analgesic impact. Azaperone has a pronounced anxiolytic and sedative effect on animals. It is widely used as an anti-stress agent to overcome anxiety caused by weaning, regrouping or veterinary manipulations. Azaperone is often used to control aggressive behavior in group housing, especially in the pig industry. The psychotropic drugs surveyed in this paper, along with direct anxiolytic action, are able to manifest additional physiological effects, which should be taken into account when developing treatment protocols for animals with behavioral problems. Further targeted studies are required to assess the pharmacological effects of anxiolytic drugs in animals.

The cardiovascular system, which includes the heart, is one of the essential systems of the human and animal body. With its participation, the blood supply of the organs takes place; it promotes the outflow of lymph from the organs and its transport into the veins, and it helps to implement the functions of the organs of immune protection, endocrine, and nervous systems. The work aims to conduct a macro-, histo-, and cytomorphometric assessment of the morphological structures of the heart of the domestic pig using complex research methods (macroscopic, histological, morphometric). Functionally mature, clinically healthy animals (n = 7) of Sus scrofa f. domestica were used for the work. According to organometallic studies, the absolute weight of a pig's heart is 487.4 ± 8.12 g; the relative weight is 0.290 ± 0.004%, and the net weight of the heart is 461.4 ± 8.0 g. According to its linear dimensions, a domestic pig's heart is elongated-narrowed (conical) type, as evidenced by the heart development index of 155.1 ± 6.3%. According to the functional load of the muscle tissues of the myocardium of the heart and its separate morphological structures (ventricles and atria) when performing particular work during spontaneous rhythmic contractions, the absolute mass of the ventricles and atria is different. The enormous mass is characteristic of the left ventricle, then the right, and the smallest for the left and right atria. Therefore, the ventricles of the heart are more functionally developed, as evidenced by the ratio coefficient (1:0.79) of the mass of the ventricles to the net mass of the heart, respectively, the ratio coefficient (1:0.21) of the mass of the atria to the net mass of the heart and the ratio coefficient (1:0.27) atrial mass to ventricular mass. Cardiomyocytes of the left ventricle have the most significant volume, cardiomyocytes of the right ventricle have a smaller volume, and cardiomyocytes of the atria have the smallest volume. Their nuclear volumes have similar values, respectively, in the left ventricle – 77.16 ± 2.01 μm3, the right ventricle – 76.02 ± 2.43 μm3, and the atrium – 75.97 ± 3.24 μm3, and the nuclear-cytoplasmic ratio is different from them: the smallest nuclear-cytoplasmic ratio, respectively characteristic of cardiomyocytes of the left ventricle, significantly more for cardiomyocytes of the right ventricle and significantly the most for cardiomyocytes of the atria. The scientific results of morphoarchitectonics, organo-, histo-, and cytometry of the heart of the domestic pig presented in the publication supplement the information on the morphological structure of the heart of domestic animals in the relevant sections of histology, comparative anatomy and are a significant contribution to clinical cardiology.
Biological activity of soils in Ukraine depending on tillage options: A meta-analysis
Authors: Lykhovyd P. V.
Published: May 2024

Tillage is one of the major factors affecting soil biological activity, resulting in changes in soil organic carbon (SOC) content, providing for carbon sequestration and shifts in carbon dioxide emission from soils. Current climate change and aggravation of global warming through the increased emission of carbon dioxide are main driving forces for global transformation of agricultural practices in the direction of climate-smart agriculture (CSA), which requires the implementation of such crop cultivation practices that result in the minimization of SOC losses and carbon dioxide emissions. The magnitude and direction of different tillage practices affecting soil biological activity are different, therefore, the best tillage options should be chosen for implementation in national CSA systems to ensure achieving the global sustainability goals. This nationwide meta-analysis, conducted for tillage practices utilized in Ukrainian agriculture examines scientifically recorded effects of moldboard tillage depth, flat cutter and no-till options on soil respiration rates and cellulose decomposition intensity in dark-chestnut and chernozem soils of Ukraine. This meta-analysis enrolled 45 studies, which met the stipulated scientific quality criteria. Statistical processing was conducted through the standardized mean difference (SMD) model without subgroups at 95% confidence interval (CI). As a result, it was determined that there is subtle impact of moldboard tillage depth on soil biological activity, which is inconclusive and unclear. The similar results were obtained for the comparison between the tillage and no-till groups, where high heterogeneity of the dataset (I2 = 82.8%) resulted in low quality of evidence for the benefits of no-till in SOC sequestration. Besides, zero fail-safe numbers support the suggestion of low-quality evidence in favor of shallow plowing advantage over deep plowing, as well as no-till against tillage. As for the difference between the groups of moldboard and flat cutter tillage, it was established that there is strong enough evidence for the advantage of flat cutter tillage in terms of soil respiration rates and cellulose decomposition intensity reduction. Further studies in this direction are required to fill the gaps in current meta-analysis, especially in terms of no-till options and their effect on biological activity of Ukrainian soils in different cropping systems.

Published: May 2024

The study investigated the impact of the interaction between soybean and rhizobia on the assimilation apparatus functioning and biomass accumulation in different soybean lines with varying photoperiod sensitivity. Nearly isogenic lines (NILs) of soybean were used, with genes E1, E2, and E3 in different allelic states: Clark (e1E2E3), L80-5879 (E1e2e3), L63-3117 (e1e2E3), and L71-920 (e1e2e3). The experimental group for each line was treated with Bradyrhizobium japonicum 634b. Plants were grown under natural long-day conditions (16 hours). Growth indicators of the studied lines, such as relative growth rate (RGR), net assimilation rate (NAR), leaf area ratio (LAR), and specific leaf area (SLA), were analyzed, as well as the content of chlorophylls A and B in the V3 and V5 developmental stages. The results demonstrate that the influence of rhizobia on the functioning of the assimilation apparatus and biomass accumulation depends on the soybean line genotype. In the study, RGR, which characterizes the biomass accumulation rate, has similar trends to those observed with NAR, characterizing the assimilation apparatus's functioning. However, each line showed its own tendencies. For instance, in the short-day variety Clark, under bacterial influence, the value of RGR and NAR decreased. Additionally, LAR and SLA values indicated a reduction in the total photosynthetic surface area and leaf dry matter. Bacterial inoculation did not significantly affect the content of photosynthetic pigments in Clark leaves. Another short-day line, L80-5879, showed no significant impact of bacterial inoculation on biomass accumulation. However, soybean interaction with Bradyrhizobium japonicum 634b led to a decrease in leaf surface area and dry matter content. Probably, bacterial inoculation supported assimilation processes by increasing auxiliary chlorophyll b in photosystem I. A general trend of significant RGR reduction in neutral-day soybean lines, L63-3117 and L71-920, was identified under bacterial influence. The interaction with rhizobia differently affected LAR and SLA values, indicating distinct adaptive mechanisms to the interactions. In conditions of almost zero plant biomass accumulation, Bradyrhizobium japonicum 634b caused a decrease in the total photosynthetic surface area and chlorophyll a and b content in the L63-3117 line. In L71-920, bacterial inoculation had no effect on the total photosynthetic surface area, while leaf dry matter and photosynthetic pigment content decreased. The obtained results demonstrate that interaction with rhizobia can influence the functioning of the assimilation apparatus in soybeans with varying photoperiod sensitivity that is determined by genotype. It is important in improving soybean productivity and its application in agricultural practices.

As a result of military actions, some territories of Ukraine have suffered technogenic loading on the environment. Of special concern is disturbed agricultural soils that are significant for food safety of the country. Soils affected by military actions require control of contamination and restoration of fertility. The studies revealed the advantages of cultivating honey clover (Melilotus albus) in war-affected soils and controlling content of heavy metals in soils and corbicular pollen from honey clover cultivated in those soils. In gray forest average-loamy soils that had been affected by military actions, nitrogen content increased 6.3% thanks to cultivation of M. albus. High nitrogen content in soil improves its fertility. Cultivation of M. albus in affected soils promoted more intensive growth of the bee families, encouraging them to gather nectar more actively. As a result, this apiary produced greater amounts of honey, corbicular pollen, and bee pollen. The conducted studies revealed heightened levels of lead, cadmium, and zinc in the war-impacted agricultural land, compared with the territory beyond the impact zone. This caused increased content of heavy metals in corbicular pollen from M. albus. Contamination of corbicular pollen from M. albus manifested in excess over the allowable norms of cadmium, lead, and zinc. At the same time, the highest coefficient of transfer from soil into corbicular pollen was found for zinc. The high degree of contamination of the soil with heavy metals as a result of military action promoted a high level of ingress of lead and cadmium into the corbicular pollen, compared with the situation in clean territory. The study results expand the available data on biomonitoring of apiary products and foraging lands in contaminated areas. Analysis of the corbicular pollen and pollen can give information about the level of environmental contamination and help evaluate the ecological state of melliferous sites. Such a monitoring can be useful for decision making regarding the protection of the environment and healthcare.

Представлено результати твердофазного аналізу комплексів флавоноїдів із Сa(II) і Al(III), які отримані із водного екстракту суцвіть золотушника канадського. Для характеристики препаратів використовували методи спектроскопії відбиття у видимому діапазоні та колориметрії (системи CIE XYZ, CIE L*a*b*). Виявлено батохромне зміщення довгохвильової смуги у спектрах відбиття комплексів відносно неасоційованих флавоноїдів, що пов’язано з підвищенням ступеню спряження у хромофорній системі унаслідок зв’язування з іонами металу. Запропоновано критерії диференційної спектрофотометрії та колориметрії для підтвердження відмінностей між комплексами флавоноїдів із Сa(II) і Al(III). Отримані результати підтверджують перспективу розширення сировинної бази для отримання біологічно активних металокомплексів флавоноїдів, удосконалюють методичну базу неруйнівного аналізу барвників типу алюмінієвих лаків, а також можуть бути використані у розробках для створення біогібридних матеріалів.

Нанокомпозити ZnO, леговані Y3+, з різним вмістом Y2O3 (1-5 %) отримано методом Печіні з нітратних розчинів. Розчини нітратів Zn2+ та Y3+ попередньо отримували розчиненням оксидів цинку та ітрію з вмістом основного компонента 99,99 % в азотній кислоті. Досліджено вплив легування оксидом ітрію на мікроструктуру, морфологію, оптичні властивості та фотокаталітичну активність нанопорошків ZnO. Властивості нанопорошків досліджували методами рентгенофазового аналізу, скануючої електронної мікроскопії (РЕМ), енергодисперсійної рентгенівської спектроскопії. На дифрактограмах отриманих порошків ZnO, легованих Y2O3 присутня в основному одна фаза.  За результатами СЕМ порошки мали конгломератну структуру. Нелегований ZnO має середній розмір частинок 43 нм, тоді як середній розмір частинок ZnO, легований Y3+ коливається від 63 до 79 нм. Встановлено, що морфологія частинок порошку в першу чергу залежить від вмісту в матеріалі Y3+. Вимірювання комбінаційного розсіяння показує, що зразки ZnO, леговані Y2O3, мають інтенсивну та чітко виражену моду A1TO, яка може бути пов’язана з деформацією частинок порошку. У спектрах фотолюмінесценції порошків ZnO зі збільшенням концентрації Y2O3 спостерігаються смуги при 400 нм, зумовлені появою домішок, які викликають дефекти міжвузлового цинку та цинкових вакансій та їх розширення зі зсувом у довгохвильову область. Фотокаталітичні властивості нанопорошків ZnO, легованих оксидом ітрію, досліджували з використанням метилового оранжевого як модельного барвника з опроміненням лампою Osram Ultra-Vitalux (300 Вт). Результати досліджень вказують на те, що отримані порошки є потенційними кандидатами для практичного застосування у фотокаталізі.

Метою дослідження був підбір білків для комплексної добавки, що входить до рецептурного складу збитих десертів типу мус: гідролізат колагену та желатин (тип А), чия ізоелектрична точка знаходиться в межах рН = 6.5–8.5, на відміну від ізоелектрична точка желатину (тип Б), яка ближча до рН збитого продукту (мусу) (рН = 4.8–5.2), і має більшу ймовірність помутніння або осадження. Досліджено застосування рибного гідролізату колагену окремо або сумісно з іншими білками для формування пінної структури збитих десертів. Було обрано оптимальну концентрацію структуроутворювачів шляхом визначення піноутворюючої здатності та стійкості піни білкових гідроколоїдів, а також підібрано їх співвідношення в комплексі для уведення в технології виробництва збитих десертів типу мус. Також було досліджено піноутворюючу здатність та стійкість піни желатину (тип А) та гідролізату колагену у порівнянні з сухим білком яйця. Гідролізат колагену має дефіцит аргініну та цистеїну порівняно з сухим яєчним білком. Великий вміст оксипроліну та оксилізину – 15.42 % – вказує на значний вміст колагену в рибній сировині. Було досліджено поверхневий натяг розчинів білкових гідроколоїдів у водному середовищі та у вершках жирністю 33 %. Наведені результати досліджень піноутворюючої здатності та стійкості піни білків показують вплив різних факторів: температури та рН розчину на досягнення бажаного результату, тобто для отримання комплексу білкових гідроколоїдів за концентрації 1.0 % та з оптимальним співвідношенням білкових компонентів гідролізату колагену та желатину (тип А) 80 : 20.
