‘Falsi’ epigrafici in Internet: una fenomenologia
Authors: Braito Silvia , Buonopane Alfredo
Published: February 2020

Several websites, especially of auction houses, have been selling for many years ancient inscriptions, especially from the Roman period, on stone, metal or other materials. Among these there are also false or dubious inscriptions, some outstandingly produced, but many of very poor quality, often sold as genuine. These are both fakes, cleverly made for fraudulent purposes, and forgeries so poor as to be hardly credible, or copies, more or less faithful, of genuine inscriptions. This paper outlines the most significant aspects of this phenomenon and examines some case studies.

Authors: Pyle Angela , DeLuca Christopher , Danniels Erica , Wickstrom Hanna
Published: February 2020

Kindergarten teachers face the challenge of integrating contemporary assessment practices with play-based pedagogy. The current study addresses this challenge by presenting a kindergarten assessment framework rooted in theory and current classroom practices, based on teacher interview and observational data collected in 20 kindergarten classrooms. Ten teachers subsequently participated in extended observations and video elicitation interviews. Results uncovered seven different assessment pathways by which teachers mobilized learning goals through play pedagogies and assessment. Based on these pathways, a comprehensive assessment framework was developed underscoring the cyclical relation between student learning goals, types of play, and assessment contexts and practices. This framework supports teachers’ negotiation and integration of assessment practices with play-based pedagogies to promote both academic and developmental learning goals.

Published: February 2020

The outbreak of the coronavirus disease-19 (COVID-19) has caused enormous stress among the public in China. Intellectual input from various aspects is needed to control the COVID-19, including the understanding of the public’s emotion and behaviour and their antecedents from the psychological perspectives. Drawing upon the cognitive appraisal theory, this study examined three cognitive appraisals (i.e., knowledge, perceived severity and perceived controllability of the COVID-19) and their associations with a wide range of emotional and behavioural outcomes among the Chinese public. Participants were 4607 citizens (age range: 17–90 years, Mage=23.71 years) from 31 provinces in China and they took part in an online survey. The results showed that the public’s emotional and behavioural reactions were slightly affected by the outbreak of the COVID-19. Moreover, the public had limited participation in the events regarding the COVID-19 but actively engaged in precautionary behaviour. In addition, results of hierarchical regression analysis revealed that the three appraisals were differentially related to the outcome variables. Theoretically, the findings highlight the utility of cognitive appraisal, as a core process of coping stress, in explaining the public’s emotion and behaviour in the encounter of public health concern. Practically, the findings facilitate the government and practitioners to design and deliver targeted intervention programs to the public affected by the COVID-19.

Authors: Jha N , Sharma KR , Niraula SR , Ghimire A , Yadav DK , Singh SB
Published: February 2020

Background: Socio-economic changes are constantly occurring in various societies with multiple reasons. Sometimes, the initiation of an educational institution, especially colleges and universities, can have a profound impact on the economy of a town. B. P. Koirala institute of Health sciences (BPKIHS) has been in existence in Dharan since 1993 (a joint project of Government of Nepal and Government of India) and it has been more than its 25 successful years.

Objectives: To examine the role of BPKIHS in changing socio-economic status of Dharan town, and to compare health and economic indicators in various cities like Dharan, Rajbiraj, Birganj, Pokhara and Nepalganj.

Methodology: Both quantitative and qualitative methods were used in this study to assess health and socioeconomic conditions. Information from Dharan was collected through Quantitative methods like Household Survey and Collection of Secondary Data, and Qualitative methods like Focus Group Discussion (FGD) and Interview with Key Informants. Similarly in Rajbiraj, Birganj, Pokhara and Nepalganj; secondary data and interview with key informants were used for gathering information.

Results: A total of 1500 households with 7198 population were surveyed in all 19 wards of Dharan. The rent of houses has increased significantly (p < 0.001) along with the use of items like electricity, radio, television, telephone, motor vehicle, bicycle, computer and gas-stoves compared to 22 years back in Dharan, which is statistically significant. Most (85.6%) of the people of Dharan go to BPKIHS for treatment and about three quarters (73.1%) of the surveyed household reported improvement in health status. More than 70% household reported improvement in socio-economic status of the people of Dharan due to the establishment of the BPKIHS. Comparing records and reports provided by various offices (secondary data) of Dharan, Rajbiraj, Birganj, Pokhara and Nepalganj, remarkable progress is seen in the developmental indicators of Dharan. Likewise key informant interview revealed noteworthy development in Dharan compared to the other four towns, predominantly due to the presence of BPKIHS, while industry/business and tourism were responsible in other towns. The participants of FGDs stated that the existence of the BPKIHS is one among the first three factors responsible for the socio-economic development of Dharan. They also reported that health, education and tourism of the town have been greatly influenced by the presence of the BPKIHS.

Conclusion: BPKIHS has made a great impact in the improvement of health and economic status of the people of Dharan. This survey revealed a positive attitude of the people towards BPKIHS. The future calls for a hand in hand approach with local population and dissemination of up to date and efficient services to further improve socioeconomic and health status of the people of Dharan.

Published: February 2020

Introduction: TB has seen resurgence associated with HIV. Tuberculosis can affect any ocular tissue. The association of HIV with TB is supposed to increase the incidence and plethora of ocular manifestations in tuberculosis.

Objectives: To study the various ocular manifestations seen in tuberculosis patients with associated HIV infection.

Material and Methods: This hospital based, cross sectional descriptive study was conducted in Tribhuvan University, Teaching Hospital, Maharajgunj, Nepal and Geta Eye Hospital, Kailali from 2010 to 2015. Diagnosed cases of pulmonary and extra pulmonary tuberculosis with HIV co infection were evaluated for ocular manifestations after excluding other opportunistic infections.

Results: Of 70 cases eligible for the study, extra pulmonary tuberculosis was seen in60% of the cases. 5 patients (7.1 %) had ocular manifestations. CD4 counts were <50/mm3 in 3 cases. Ocular involvement was seen in the form of choroidal granulomas, papillitis, cranial nerve palsy, retinal vasculitis and central serous chorioretinopathy.

Conclusion: This study demonstrated that ocular involvement is a frequent finding in cases with tuberculosis and HIV. Ocular findings are more common in cases with lesser CD4 counts. As ocular tuberculosis can be visually devastating, we recommend regular ocular evaluation of all patients with HIV and systemic tuberculosis.

Reproducing ̶w̶h̶i̶c̶h̶ Nation?: White Pro-Natalism and Ontario’s Recent Fertility Treatment try Program
Authors: Cranston-Reimer Sharlee
Published: February 2020

This paper reads the recent Ontario fertility program as a pro-natalist neo-eugenics project that is enacted through the logic of homonationalism in Canada. It demonstrates that the program’s use of pinkwashing through an emphasis on LGBTQ+ people obscures not only the inaccessibility of fertility treatment both on individual and structural levels particularly to Indigenous people, people of colour and poor people, but also to other minoritized populations, who have survived but continue to face a genocidal government. The paper moves past questions of inclusion to question the nation-state’s priorities with regard to the allocation of $50 million to facilitate the reproduction of primarily white people in the context of suicide crises on reserves and Black youth experiencing alarming rates of police violence. When the nation-state is positioned in terms of these factors, it becomes clear that it is using coded strategies to foster the building of a wealthy white citizenship.
"The Theatricality of the Emulsion!"
Authors: Ogrodnik Benjamin
Published: February 2020

This article reexamines the career of Roger Jacoby (1945–1985), an abstract painter and gay liberation activist who became renowned for processing film in his darkened bathtub and for films that featured his partner, Ondine, the Andy Warhol Superstar. Through a consideration of film shorts made in the 1970s and 1980s, the article argues that Jacoby’s principal innovation was the exploration of hand-processing, which resulted in films that resembled abstract expressionist paintings in motion. Additionally, it considers hand-processing as an overlooked, albeit powerful, vehicle for expressing non-normative sexuality in American avant-garde film. It situates Jacoby alongside gay filmmakers Kenneth Anger, Gregory Markopoulos, and Jack Smith, and considers how hand-processed media can generate a “corporealized” spectator and disrupt patterns of filmic illusionism and heterosexist protocols of sexual/gender representation.

Authors: Sabitov E. E. , Dusembinov D. S. , Bazarbayev D. O.
Published: February 2020

The paper deals with the quality of gas concrete by using a number of process technologies that can significantly improve the potential of the added components. The proposed technology for composite gas concrete production improves its physical-and-mechanical properties due to the use of a rotary-pulsation apparatus, which creates high-frequency vibrations accompanied by cavitation and produced a high-quality polymer emulsion and the aluminum powder. Due to high-quality saponification, the gasifier evenly distributes in the concrete paste structure and reacts with the cement binder, thereby creating a uniform pore space. And the polymer emulsion envelopes pores and improves the material hydrophobicity and strength.

Published: February 2020

Anhand einer qualitativen Interviewstudie mit älteren Menschen zum Thema Tod und Sterben sind forschungspraktische Herausforderungen im Umgang mit den Themen Einverständnis, Anonymität und Verschwiegenheit aufgetreten. Diese Herausforderung betrifft dabei nicht nur vulnerable Interviewpartner, jedoch stellt sich bei dieser Personengruppe die Frage nach einem besonderen Schutz aus forschungsethischer Perspektive. Auf Basis dieser eigenen empirischen Erfahrung ist folgende forschungspraktische Frage der Erfüllung und Dokumentation von datenschutzrechtlichen Bestimmungen aufgekommen: Kann eine informierte Einwilligung anstelle der Schriftform auch auf Tonband gegeben werden? Vor diesem Hintergrund beschäftigt sich der Beitrag mit Möglichkeiten, wie datenschutzrechtliche Bestimmungen und deren Dokumentation erfüllt werden können, ohne dass sich dieser Prozess negativ auf eine (notwendige) Vertrauensbildung im Rahmen der Interviewsituation auswirkt. Der Beitrag diskutiert hierzu den Vorschlag, das Einverständnis und deren Dokumentation nicht schriftlich, sondern in Form einer verbalen Aufzeichnung durchzuführen. Hierzu werden sowohl forschungsethische als auch datenschutzrechtliche Aspekte aufgegriffen und eingeordnet. Aus der Diskussion werden schließlich konkrete und praxisorientierte Hinweise für Forschende abgeleitet.
Design of the third-generation neutron spallation target for the CERN’s n_TOF facility
Authors: Esposito Raffaele , Calviani Marco
Published: February 2020

The neutron Time-Of-Flight (n_TOF) facility at the European Laboratory for Particle Physics (CERN) is a pulsed white-spectrum neutron spallation source producing neutrons for two experimental areas: EAR1, located 185 m downstream of the spallation target, and EAR2, located 20 m above the target. The facility is based on a lead target impacted by a high-intensity 20 GeV/c proton beam. It is designed to study neutron-nucleus interactions for neutron kinetic energies from a few meV to several GeV, with applications in nuclear astrophysics, nuclear technology, and medical research. The facility is undergoing a major upgrade in 2019–2020, which will include the installation of the new third-generation target. The second-generation target consists in a water-cooled lead cylinder, while the new target will be cooled by nitrogen to avoid erosion-corrosion phenomena and contamination of the cooling water with radioactive lead spallation products. The new design will be optimized also for the vertical flight path. The operation of the new spallation target will start in 2021. This paper presents an overview on the evolution of the design and on the related R&D activities (including beam irradiation tests) carried out to ensure the best performance for both experimental areas and avoid the contamination issues of the previous targets.
Strategic target setting in the heptathlon
Authors: Dinnie Alf , O’Donoghue Peter
Published: February 2020

The purpose of this study was to examine scoring within the women’s Heptathlon to identify areas of performance where athletes could most improve their points total and propose an approach to target setting. Performance data were gathered from publically available sources for 409 performances of 155 heptathletes at 19 international championships between 2004 and 2017 inclusive. Based upon the interquartile ranges, the largest spread of points were seen for the High Jump and Javelin. Year to year improvement was analysed using the 186 pairs of performances by the same athletes in consecutive calendar years. This showed that the disciplines with the most scope for improvements were the Long Jump, High Jump and Javelin. The proposed target setting approach can be used to identify which disciplines an athlete should focus on to maximise improvement in their total points and to estimate the probability of the athlete exceeding the target that has been set. The approach should be used in conjunction with knowledge of the wider context of the athlete’s recent heptathlon performances.
Interactive minutes generation system based on hierarchical discussion structure
Authors: Miura Hiroya , Takegawa Yoshinari , Terai Asuka , Hirata Keiji
Published: February 2020

This research leads to the development of a system that generates minutes while the system and user interactively structure and summarize the discussion. The system can look back on a meeting from a specific viewpoint or purpose by sending an inquiry to the minutes, receiving the result, and performing a new operation. To improve the reusability of the minutes, it is necessary to understand the semantic relationships among utterances at a deep level. We therefore propose a novel tree structure called the discussion time-span tree for representing a hierarchical discussion based on the relative importance of utterances derived from the meeting. The discussion time-span tree is a binary tree, each leaf of which corresponds to an utterance. Adjacent relevant utterances are hierarchically grouped, and the most important utterance becomes a head. In this way, the tree represents the implicit meaning and intention contained in meeting records, and can be used for summarization. Our system aims to grasp the main point of the meeting by interactively manipulating this tree structure and giving different viewpoints to each system user. An evaluation of the important utterance extraction using the proposed system showed that the score of ROUGE-2 was higher than that of the existing document summarizing technique. In a subsequent user evaluation conducted with ten participants, we found that the system can be used to grasp conference contents efficiently. The results of both evaluations demonstrate the usefulness of the system.

Published: February 2020

The fishing industry is an important component of the economy of Ukraine at the present stage of development. The development and implementation of the innovative technologies in fish farming and fish processing require mandatory and ongoing analysis of a fish market infrastructure. The demand for food protein, which is characterized by a balanced amino acid content is provided by fish and seafood at 20–30 %. The aim of this work was to understand a current state of a fish products market in Ukraine, its pricing and consumption. Based on the specialized literature the evaluation of a current state of fish and fish products consumption in Ukraine and own studies of the price category of fish products in Ukraine in recent years were conducted. We studied fish and fish products consumption per year per capita in Ukraine over the last 20 years, assortment of fish in Ukraine, the import of fish and fishery products by species, the product prices in UAH per kg both in previous years and today. According to international medical standards the annual consumption of fish and seafood should be 20 kg per person. At the same time in Ukraine according to the State Statistics Committee on the 01.01.2019 14.5 kg of fish and seafood came out per capita. In 2018–2019 herring traditionally remained a leader of consumption in Ukraine. Ukraine also imported such species of fish: mackerel, hake, herring, salmon, pilchards, pollack, capelin, sardines, notating. In addition pangasius, shrimp, blue whiting, mussels, squid, saury, Jack mackerel, sea bass, tuna, flounder, anchovies, smelt, cod, salmon and other species of fish, caviar and seafood are imported in Ukraine. The investigated assortment of fish in Ukraine is represented both domestic and imported products. The domestic production are: carp, pike, capelin, herring, mackerel, sprat, the imported products are: flounder, perch, pangasius, salmon, butter, hake, Pollock, capelin, nototenia, herring, mackerel, cod, tuna, tilapia (sole), sea trout, whiting and so forth. It is established that the condition of a fish market in Ukraine is affected by an unstable economic and political situation in the country, low solvency of the population, corruption and the high payables of the enterprises. In Ukraine a tendency towards a decrease in the volume of fish and fish products consumption by the population of Ukraine is observed annually, which is a consequence of the decline in fish catch and fish production, depreciation of fixed assets and a lack of financial support to the fishing industry.
The intensity of the processes of oxidative modification of proteins and the activity of enzymes of the antioxidant protection system of broiler chickens under the action of vitamins E and C
Authors: Romanovych L. , Kurtyak B. , Mudrak D.
Published: February 2020

Chickens in the control group received a standard ration, the first experimental – ration with the addition of tocopherol acetate, the second experimental – ascorbic acid, and the third – a complex of these vitamins. On the basis of the conducted researches the influence of vitamin supplements on the indexes of oxidation intensity of lipid and protein structures was analyzed. The intensity of the processes of oxidative modification of proteins largely depends on the level of vitamins E and C in the ration of broiler chickens. Supplementation with vitamin C and with vitamin E resulted in an inhibitory influence on the content of OMP products, the level of which is largely regulated by the enzyme and non-enzymatic links of the antioxidant protection system. Searches have shown the stimulating influence of the addition of vitamins on the activity of antioxidant enzymes. In particular, SOD activity increased by 19 % on the 34th day, by 32 % on the 41st day, whereas glutathione peroxidase activity was 5.7 and 20.8 %, respectively, compared to the control chickens group. An increase in the activity of antioxidant enzymes occurred against the background of a decrease in the intensity of oxidation processes. At the same time, there was also an increase in the content of recovered glutathione in the blood of chickens of the second and third experimental groups at 34th and 41st days of age. Thereby, searches have shown that supplementing the ration with vitamins E and C with a positive influence on the organism's adaptive capacity and antioxidant potential, which is extremely important to ensure the metabolic homeostasis of chickens during critical periods of their cultivation.

The surface waters of the estuaries of the estuary are mostly characterized by low quality, which was formed as a result of considerable anthropogenic loading and transformation of the catchment area. The monitoring data of the ecological and sanitary status of the surface waters of the Basov Kut reservoir are presented, as well as the results of accounting for dead fish due to the frosts that occurred in the mouth of the Ustye River during 2011–2017. It is established that the Bas Basin is not suitable for recreational use. Amateur fisheries are also a danger to the population, as lactose-positive E. coli, the Staphylococcus aureus index, the Enterococcus microorganism index, Lamblia intestinalis cysts and eggs are detected in this reservoir annually. In 2017, cholera vibrios (Vibrio cholera non O1) were detected. Hydrochemical indicators, in particular in 2018, revealed inconsistency with the following indicators: odor – 2 points; color 3; BOD5 – 6.5–7.5 mgO2/dm³; COD 40–50 mgO2/dm³. In samples tested for sanitary – microbiological and parasitological parameters, cholera – like vibrio (non O1) was detected. The deterioration of water quality by the content of biogenic elements, in particular, compounds of Nitrogen and Phosphorus, which leads to increased eutrophication of the reservoir. The “flowering” of water in 2018 began in the third decade of June and lasted until October. This process harms not only hydrobionts, but also humans, as blue-green algae toxins can accumulate in fish tissues and cause poisoning when consumed by such products. In addition, there was a significant percentage of fish that did not meet the requirements of DSTU 2284: 2010 in terms of organoleptic characteristics. The greatest damage to the populations of fish that inhabit the Estuary during the fatalities was caused in 2012. When the estimated loss of fishery resources amounted to 377.4 thousand individuals, according to scientists and control bodies. Annual fatalities have led to quite significant losses of populations of industrially valuable fauna. A significant loss of fishery resources was noted in 2017 – about 10.32 thousand. It was noted that the following populations of fish were most affected by the frost in the estuary: Rutilus rutilus, Scardinius erythrophthalmus, Leucaspius delineatus, Perca fluviatilis, Carassius gibelio, Tinca tinca, Esox lucius, Sander luciocaper, Abracerperis This poses a significant threat to the further reproduction of ichthyofauna in the mouth of the Ustya River, and also calls into question the possibility of amateur fishing in these sites.

The data on the concentration of structural proteins of plasmolemma of the absorption enterocytes of the cattle fetus in the early fetal period are presented. Changes in the protein composition of the apical and basolateral membranes of enterocytes are manifested, characterized not only by changes in their ratio within different cell domains, but also by the dynamic redistribution of the number of different fractions of polypeptides between the poles of these cells. Analysis of the results of electrophoresis of apical membranes of the cattle fetus enterocytes in the early fetal period indicates a decrease in the content of low molecular weight protein fractions and an increase in high molecular weight. In the apical membranes of enterocytes of two-month-old cattle fetus, 25 protein fractions with a molecular weight of 9.6 to 205 kDa were detected. In the basolateral membranes revealed 23 protein fractions with a molecular weight of 9.6 to 120 kDa. High molecular weight fractions of polypeptides with molecular weights of 250 kDa and 300 kDa appear from the age of three months of embryos of calves. In the basolateral membranes of enterocytes, there is a slight decrease in the content of low molecular weight protein fractions, and from the four months of age of cattle fetus, high molecular weight fractions of polypeptides with molecular weights of 22.5 kDa and 155 kDa appear, which are absent in basolateral membranes of enterocytes. Two-month-old fetus lack proteins with a molecular weight of 19 kDa, 24 kDa, and 66 kDa in the apical part, whereas proteins with a mass of 22.5 kDa, 155 kDa, 170–185 kDa, and 205 kDa are absent on the basolateral membrane. In the apical membrane of enterocytes significantly more proteins with a low molecular weight of 9.6-14.2 kDa (1.56 times; P ≤ 0.001), whereas in the basolateral membrane a significantly higher concentration of proteins with a molecular weight of 15.5 kDa (2.06 times; P ≤ 0.001) and 17 kDa (3.62 times; P ≤ 0.001).

Published: February 2020

A study on amphibian fauna at the lowland dipterocarp forest of Lubuk Semilang Recreational Park, Langkawi, Kedah, Peninsular Malaysia was conducted between December 2018 and June 2019. We recorded 18 species of amphibians from 14 genera and 6 families. These include seven new records for Lubuk Semilang, which are Fejervarya limnocharis, Limnonectes hascheanus, Megophrys aceras, Kaloula pulchra, Microhyla butleri, Pulchrana laterimaculata, and Polypedates discantus. We also recorded a new anuran record for Langkawi Archipelago, Pulchrana laterimaculata, and two endemic species of Malaysia, Leptobrachium smithi and Limnonectes macrognathus. Results from this survey indicate the amphibian species of the Langkawi Archipelago has increased from 28 to 29 species.

Archaic-Age Architecture in Northwest Colorado
Authors: Pool Kelly , Reed Charles
Published: February 2020

Archaic-era hunter-gatherers in the Wyoming Basin—which extends across southwest Wyoming and northwest Colorado—built domed or conical architectural features, with some exhibiting far more substantial construction than others. These structures are often archaeologically preserved as large elliptical basins, defined by charcoal-stained sediment that filled habitation footprints after abandonment. Many of these basins, or house pits, are probably residential remains, although some may have had other uses. The recent discovery of 32 house pits in Colorado’s Yampa Valley in the Sand Wash Basin has expanded the regional dataset, increasing our understanding of Archaic-era lifeways in northwestern Colorado. These discoveries further demonstrate the highly variable nature of Archaic-era structures, reflecting the adaptability of a mobile lifestyle to a specific place and time. Archaic-era use of these features in northwest Colorado occurred between about 8100 and 3755 cal B.P., demonstrating the usefulness of such shelters across a wide range of climate regimes. The greatest numbers were built between 6800 and 6000 cal B.P., coinciding with the mid-Holocene thermal maximum, when the residential settlement pattern grew more restricted, centering on water, food, and shelter resources. As the warm, arid climate ameliorated after 5500 cal B.P., use of such shelters began to decrease, demonstrating a return to higher residential mobility with greater availability of resources in the cooler, wetter climate. A comparison of Yampa Valley house pits with northern Wyoming Basin house pits indicates that Archaic-era people utilized similar structures as part of a highly adaptable mobile lifestyle for thousands of years across the Wyoming Basin.

Проаналізовано успішність інтродукції в дендрологічному парку "Асканія-Нова" Amygdalus ledebouriana Schlecht. – виду міжнародного созологічного статусу. За підсумками різнобічних досліджень встановлено, що він виявляє високий ступінь адаптації до регіональних природно-кліматичних умов. Висота рослин від 1,1 м до 1,3 м. Середні розміри: листків 4,3±0,12 см × 1,1±0,08 см, листочків оцвітини 0,96±0,09 см × 0,56±0,05 см, кістянки – 2,5±0,08 см × 2,1±0,1 см, кісточки – 1,9±0,07 см × 1,4±0,06 см. Маса 100 штук середніх за розміром кістянок 89,9 г. Належить до рослин із раннім початком поновлення вегетації, за дендроритмотипом – до ранньо-середніх рослин, за часом зацвітання – до ранньо-весняних. Тривалість періоду вегетації складає 213–232 дні, фенологічний лаг (від початку цвітіння до повного дозрівання плодів) – 131–133 дні. Ріст пагонів триває 92±11 дні, річний приріст пагонів стабільний, 15,5±0,7–16,1±0,7 см. A. ledebouriana щорічно рясно цвіте і в окремі роки плодоносить, утворюючи життєздатні плоди, які за певних способів допосівної підготовки мають високу ґрунтову схожість. Виду властива висока вегетативна репродуктивна здатність, завдяки чому він збільшує свій життєвий простір та закріплюється в нових місцях зростання. У дендропарку A. ledebouriana вирізняється значною зимостійкістю, посухостійкістю від середньої до високої (зазвичай, "підгоряють" кінчики листків, іноді листки жовтіють). У деякі роки листки уражаються клястероспоріозом (дірчастою плямистістю), а окремі пагони – моніліозом. Ураження інших органів рослин та іншими біотичними чинниками не спостерігали.
