Вплив гербіцидів на забур'яненість культур сосни звичайної (Pinus sylvestris L.) в умовах Київського Полісся
Authors: Хромуляк О. І. , Савущик М. П. , Шлончак Г. А.
Published: June 2020

Наведено результати досліджень щодо випробовування гербіцидів під час здійснення хімічних доглядів за лісовими культурами. Для дослідів використано гербіциди Річард, Пікадор, Гліфовіт і Булон у комбінації з прилипачем Олемікс і без нього. На дослідній ділянці трав'яна рослинність була представлена типовими для Київського Полісся видами: куничник наземний (Calamagrostis epigejos (L.) Roth.), злинка канадська (Erigeron canadensis L.), щавель горобиний (Rumex acetosella L.), тонконіг звичайний (Poa trivialis L.), напівчагарник ожина (Eubatus). Найбільш забур'яненими були міжряддя. Тут переважав куничник наземний, а однорічні бур'яни, переважно злинка канадська, траплялися поодиноко. На схилі і дні борозен також переважав куничник та у незначній кількості росли однорічні види. На дні борозен і на їх схилах кількість бур'янів була практично однаковою. Досліди закладено на лісових культурах 2018 року. Культури створено у лісовому фонді ДП "Київська лісова науково-дослідна станція" на суцільному зрубі, по борознах, в умовах свіжого субору. Доповнення культур здійснювали навесні 2019 року. Для обробляння рослин використовували ручні оприскувачі. Під час хімічного догляду за лісовими культурами сосни звичайної (Pinus sylvestris L.) гербіцидна дія препаратів полягала у пригніченні росту небажаної трав'яної рослинності та в частковому її знищенні. Застосування гербіцидних препаратів Річард, Гліфовіт і Булон призвело до знищення від 52 до 68 % багаторічних бур'янів. Найменше багаторічників було знищено гербіцидом Пікадор, тільки 37 %. Причому такий результат було досягнуто як застосуванням препарату Пікадор у комбінації з прилипачем Олемікс, так і без нього. Водночас, Пікадор повністю знищив однорічні бур'яни. Стосовно дії гербіцидів у комбінації з прилипачем встановлено, що його застосування істотно не впливало на ефективність гербіцидів. Усі гербіциди спричинили відпад сосни. Найбільше пошкоджень (21 %) виявлено під час застосування гербіциду Річард. Встановлено, що хімічний догляд негативно вплинув на однорічні рослини сосни звичайної, якими було доповнено лісові культури.
Davids Still Exist among Goliaths: A Story of Modest Self-Access Centre Establishment and Survival in Times of Economic Decline
Authors: Papadima-Sophocleous Salomi
Published: June 2020

In a university setting, self-access language learning centres (SALLC)s are generally created out of the need to support students and other members of the university and extra-mural community to explore and expand their language learning horizons. The nature of SALLCs depends on the needs of each institution and its community. They range from fully self-directed to semi-guided, from virtual online-self-access centres (OSAC)s to real centres, with traditional print, and more contemporary electronic and digital materials.

While much of the research so far has dealt with different aspects of SALLCs, particularly of prominent ones, this article reports on the case of a small-scale SALLC, which was designed and developed, and which has operated, during difficult circumstances. This report describes how despite the administrative and financial constraints faced during the establishment of the host university and language centre, current theories and practices in SALLC were still taken into account. Also, despite these difficulties and the economic constraints being endured by the country as a whole, a number of strategies were implemented enabling the SALLC to be accessible to all students, with a view to promoting both autonomy and lifelong learning.

The data used consisted of field notes collected during the period of operation as well as results from an evaluation of the use of different learning pathways on offer. Finally, the challenges still being faced as the SALLC enters a new period in its development are outlined.
Gas-Phase Ion Exchange into Zeolites: A Proposed Set-Up Design
Authors: Faouzi Ayari  , Emna Mannei
Published: June 2020

The aqueous and solid-state ionic exchanges are widely used for introducing chromium ions into ZSM-5 zeolite (Si/2Al = 30 and 50). However, along with their benefits, these exchange methods presented some disadvantages, essentially related to the wasted chemicals. As alternative, we investigated the exchange of Cr and Mo ions into ZSM-5 zeolite by conventional sublimation. Unfortunately, this method exhibited many constraints which were essentially related to the discrepancy between the exchange and the sublimation temperature values (Texch and Tsub, respectively). In this work, we proposed a general design of an experimental set-up required for introducing metallic ions into zeolites regardless Texch and Tsub values. Technically, the implementation of the proposed set-up requires two tubular furnaces, two temperature regulators and a linear reactor.
The Natural Environment as an Agent in the Design and Operation of the Bournemouth Air Festival
Authors: Fox Dorothy
Published: June 2020

There is a growing body of literature that discusses the protection of the natural environment in relation to events and festivals. However, there is little that demonstrates the value of nature to event stakeholders. This research contributes by recognizing the natural environment
as an agent in the design and operation of the Bournemouth Air Festival, which is held on land, sea, and in the air. The case study was undertaken iteratively and within an inductive approach drawing on multiple sources of evidence, namely in-depth and unstructured interviews with stakeholders;
observation and documentary evidence. In the absence of a theoretical proposition, the analytical strategy adopts a multidisciplinary approach to develop a case description. The study reveals first, the value of natural capital to the Festival and secondly, it develops a new model demonstrating
the variability of the natural environment as an agent in the design and operation of the event. This shows that changes in the environment have occurred historically, recently, and even sometimes during the Festival. The latter create the greater challenges for the organizers as they may
be consistent in their agency or inconsistent and further divide between those which are predictable, those which are foreseeable, and those which are unforeseeable. The article concludes with a discussion of the effect nature's actions have on event planning in its various forms and other
implications for management.

Authors: Ahmad Mohd Hanafiah , Hamid Mohd Rashid Ab
Published: June 2020

This paper aims to provide a theoretical support on how culture influence the implementation and acceptance of assessment centres (ACs) in Malaysia. This paper aims to contribute to this research gap by exploring the implementation and acceptance of ACs in Malaysia, as an example of an Eastern, and developing, country. In this context, to analyse how culture influence the design and implementation of ACs, the model of cultural fit is reviewed to explain how culture influences human resource practices and ACs practice. Findings from the literature review show that model of cultural fit can be used to explain how physical and socio-political may influence internal and organisational work culture and, therefore, human resource practices. On the other hand, to understand the influence of culture on acceptance of ACs, organisational justice theory and employee engagement theory are reviewed and used to explain how candidates react to selection process. Findings from literatures search shows that culture may have influence on how ACs participant perceived fairness of the process by which outcomes are reached, or decisions are made

The ideal of whole knowledge as a principle of the organization of science and society: a glance at 4338 from the beginning of the XXI century
Authors: Pirozhkova Sofia
Published: June 2020

The paper analyzes the model of the scientific activity and social order organization, presented in the unfinished novel by V. F. Odoevskij «4338: St. Petersburg’ letters». It is shown that the novel has a futurological character and futurological success. The methodological principles articulated by Odoevskij are analyzed in detail, it is shown how these principles allow anticipating the general direction of development of organizational forms of scientific activity, some conceptual shifts in understanding the essence of scientific knowledge, as well as several social innovations. The author compares Odoevskij's methods of anticipating the future and methodological tools, used by classical futurology, on one hand, and Futures studies — on the other. It is proved that since Odoevskij constructs his futurological scenario in response to the contradictions in the development of modern science and modern society revealed by him earlier, this scenario has not only a prognostic, but also a utopian value — as an ideal model of the structure of science as a cognitive activity and as a social institution, which is capable to give fruitful principles of the organization of society as a whole.
Dialectical epistemology
Authors: Kremen' Roman
Published: June 2020

The article is devoted to epistemology. It is revealed that progress in the direction of the true representation of a natural object occurs when a meaningful representative definition of it organically connects two fundamental dialectical epistemological flows. The first is the intuitive heuristics that are born of the imagination and are purely subjective nouns, the Genesis of which is idealistic. The second is the sensory-rational experience of observation-apperception, which is a purely external, in relation to the subject, induced reaction due to the material nature of the object. The results of verification activities are an indicator of the organic connection of the indicated flows. It is shown that the «parallel» materialistic and idealistic lines in epistemology point to two equal oppositional realities, the contradiction of which, according to the dialectical method of reasoning, is removed through the constitution of a single metaphysical substance — the spirit. These lines are clearly separated through the reflection of two heterogeneous cognitive components. The necessity of changing paradigmatic guidelines in the philosophy of natural science from mechanistic-atomistic to organismic is discussed. In the preceding part, a criticism is rejected of metaphysics of scientism.

It should be noted that early diagnosis and treatment of mental disorders that occur the use of psychoactive substances (both episodic and systematic ones) for this contingent of respondents is a very complex issue, closely related to the destigmatization of psychiatric care, the success of psychoeducational projects on microsocial and family macrosocial (staff of educational institutions, social services, general practice) levels. It is periodically detection and early care in the vast majority of cases which have been determined the prognosis of mental illnesses and social consequences.

Objective – based on a systematic, interdisciplinary approach we have the purpose to develop a model and the algorithm for providing medical and social care to adolescents with addictive behavior who use psychoactive substances.

Materials and methods. A systematic, interdisciplinary approach is used.

Results. Trends in the use of psychoactive substances by adolescents and young people will be described in such a way. Most of the respondents when taking various psychoactive substances were mainly in the area of relatively “safe” (1-7 points) or “dangerous use” (8-15 points), but without harmful effects or states of dependence. For adolescents with addictive behavior who used psychoactive substances, depending on the degree of use, we developed a model and the algorithm for medical and social care. Proposed measures were mainly psychotherapeutic and psychocorrectional in their nature.

Conclusions. Based on the obtained data, the study and testing of addictive behavior of adolescents, the influence of social factors, premorbid mental disorders were developed and a model and the algorithm for providing medical and social care to adolescents who use psychoactive substances at different levels of care were tested.

Authors: Borova
Published: June 2020

Reformation of the higher education system in Ukraine requires innovative changes in the priorities of educational policy, improvement of its content, information and technological support of the educational process. So the task to determine such methods of interaction between teachers and future teachers of preschool education institutions in order to stimulate their successful professional development arises. One of the tasks of modernizing higher pedagogical education is to develop students' information and communication competence. The problem of professional training of future teachers has been described in researches of the following scientists: V. Benera, O. Bogich, I. Bogdanova, A. Bogush, G. Bielienka, N. Gavrysh, T. Zharovtseva, L. Zdanevych, I. Kniazheva, T. Ponimanska, M. Roganova, T. Tanko, N. Lysenko, N. Malinovska and others. Issues of using multimedia presentations in the training of future specialists were studied by the following scientists: Y. Avsiukevych, V. Bykov, M. Zholdak, I. Zakharova, V. Klochko, A. Kolomiyets, Y. Mashbyts, I. Pidlasyi, O. Spivakovskyi, A. Khutorskyi and others. Multimedia presentation is a didactic tool that allows to transmit information in a visual and schematic form for improvement its perception and increasing its value. The effectiveness of using multimedia presentations is achieved when the following didactic conditions are met: – a harmonious combination of oral presentation of the material during a lecture session and knowledge acquired by students during practical and laboratory classes with the information of a multimedia presentation; – ensuring maximum implementation of multimedia presentation functions, in particular, stimulating thinking, memory and attention of the higher education students; – interactive orientation of multimedia presentation; – the rational ratio of the time allocated to lecturer to familiarize students with the content of topic of the lecture session and the time allocated for a multimedia presentation; – ensuring the perception of information using the maximum number of analyzers; – availability of information for perception and analysis by higher education students; – rational dosing of the volume of information presented using a multimedia presentation. Comparative analysis of the final exam scores of students in the control and experimental groups of the higher education students confirmed our hypothesis that multimedia presentations are the effective means of increasing the level of knowledge of students, forming their information and communication competence

Key words: Keywords: older preschool children, multimedia presentation, language development of children, pre-school teacher.
Hacia una Ecología Política Latinoamericana del Desastre Urbano: Algunos apuntes para su discusión
Authors: Castillo Oropeza Oscar Adán
Published: June 2020

En este texto, se propone desde la perspectiva de la Ecología Política Urbana (EPU), plantear algunas reflexiones sobre lo que podría considerarse como Ecología Política Latinoamericana del Desastre Urbano. El objetivo es comprender a los desastres urbanos como procesos socioambientales, relacionados con la urbanización de la naturaleza y no como simples fenómenos naturales. Se trata de un primer acercamiento a una caracterización y definición de los desastres en la ciudad como objetos de estudio híbridos, el cual pretende escapar a los estudios tradicionales sobre ecología política y desastres. Finalmente, se concluye que el enfoque de la EPU ofrece una serie de elementos novedosos para la construcción de un futuro programa de investigación sobre desastres urbanos, el cual se necesita poner a prueba en un futuro próximo.

Authors: Molpeceres María Celeste , Ceverio Rocío , Brieva Susana Silvia
Published: June 2020

La aplicación de agroquímicos para proteger cultivos y controlar enfermedades, plagas y malezas es una práctica habitual en la agricultura. Esta tendencia a nivel mundial comienza alrededor de la década de 1950, en consonancia con los postulados de la denominada ‘Revolución Verde’, y a partir de entonces distintas instituciones tanto internacionales como nacionales han intentado regular su uso y aplicación. El artículo busca explicar los procesos de producción de instrumentos de regulación en materia de agroquímicos en Argentina. Para eso, desde una perspectiva constructivista, y partiendo de estudios previos, se reconstruye el marco normativo nacional e internacional en términos de trayectoria socio-técnica, desde los años 1950 en adelante, a partir del análisis de documentos, programas, códigos, directrices, convenios y acuerdos internacionales, así como leyes y otros instrumentos de regulación y control de uso, aplicación y comercialización de agroquímicos en Argentina.

and 80% patients presented with anemia and thrombocytosis at admission, respectively.Almost tumors were unifocal locating in the right lobe of the liver and 58.2% cases belonged to standard risk group. Assessing treatment protocol in 54 HB patients demonstrate that number of patients undergoing hepatectomy after preoperative chemotherapy accounted for 82%. The most frequent acuteside effects after chemotherapy were myelotoxicity and infection. The proportion of fatal and relapsed cases was 31.5% and 12.9% respectively. Overall and event-free survival rate of the study after 3 years was 65.7% and 68.1% individually.
Conclusion: Hepatoblastoma is a rare malignant childhood disease, pretty good response to chemotherapy followed by surgery. However mortality rate is rather high compared to worldwide reasearchs. Thus development of liver transplant is necessary to improve survival rate.

Asteroid crater retention ages have unknown accuracy because projectile–crater scaling laws are difficult to verify. At the same time, our knowledge of asteroid and crater size–frequency distributions has increased substantially over the past few decades. These advances make it possible to empirically derive asteroid crater scaling laws by fitting model asteroid size distributions to crater size distributions from asteroids observed by spacecraft. For D > 10 km diameter asteroids like Ceres, Vesta, Lutetia, Mathilde, Ida, Eros, and Gaspra, the best matches occur when the ratio of crater to projectile sizes is f ∼ 10. The same scaling law applied to 0.3 < D < 2.5 km near-Earth asteroids such as Bennu, Ryugu, Itokawa, and Toutatis yield intriguing yet perplexing results. When applied to the largest craters on these asteroids, we obtain crater retention ages of ∼1 billion years for Bennu, Ryugu, and Itokawa and ∼2.5 billion years for Toutatis. These ages agree with the estimated formation ages of their source families and could suggest that the near-Earth asteroid population is dominated by bodies that avoided disruption during their traverse across the main asteroid belt. An alternative interpretation is that f ≫ 10, which would make their crater retention ages much younger. If true, crater scaling laws need to change in a substantial way between D > 10 km asteroids, where f ∼ 10, and 0.3 < D < 2.5 km asteroids, where f ≫ 10.

Evolved stars near the tip of the red giant branch show solar-like oscillations with periods spanning hours to months and amplitudes ranging from ∼1 mmag to ∼100 mmag. The systematic detection of the resulting photometric variations with ground-based telescopes would enable the application of asteroseismology to a much larger and more distant sample of stars than is currently accessible with space-based telescopes such as Kepler or the ongoing Transiting Exoplanet Survey Satellite mission. We present an asteroseismic analysis of 493 M giants using data from two ground-based surveys: the Asteroid Terrestrial-impact Last Alert System (ATLAS) and the All-Sky Automated Survey for Supernovae (ASAS-SN). By comparing the extracted frequencies with constraints from Kepler, the Sloan Digital Sky Survey Apache Point Observatory Galaxy Evolution Experiment, and Gaia we demonstrate that ground-based transient surveys allow accurate distance measurements to oscillating M giants with a precision of ∼15%. Using stellar population synthesis models we predict that ATLAS and ASAS-SN can provide asteroseismic distances to ∼2 × 106 galactic M giants out to typical distances of 20–50 kpc, vastly improving the reach of Gaia and providing critical constraints for Galactic archeology and galactic dynamics.
New Grids of Pure-hydrogen White Dwarf NLTE Model Atmospheres and the HST/STIS Flux Calibration
Authors: Bohlin Ralph C. , Hubeny Ivan , Rauch Thomas
Published: June 2020

Nonlocal thermodynamic equilibrium (NLTE) calculations of hot white dwarf (WD) model atmospheres are the cornerstone of modern flux calibrations for the Hubble Space Telescope and for the CALSPEC database. These theoretical spectral energy distributions (SEDs) provide the relative flux versus wavelength, and only the absolute flux level remains to be set by reconciling the measured absolute flux of Vega in the visible with the Midcourse Space Experiment values for Sirius in the mid-IR. The most recent SEDs calculated by the tlusty and tmap NLTE model atmosphere codes for the primary WDs G191-B2B, GD 153, and GD 71 show improved agreement to 1% from 1500 Å to 30 μm, in comparison to the previous 1% consistency only from 2000 Å to 5 μm. These new NLTE models of hot WDs now provide consistent flux standards from the far UV to the mid-IR.
On Arrival Time Difference Between Lensed Gravitational Waves and Light
Authors: Suyama Teruaki
Published: June 2020

It is known that geometrical optics no longer applies to gravitational lensing if the wavelength of a propagating wave becomes comparable to or larger than the Schwarzschild radius of a lensing object. We investigate the propagation of gravitational waves in wave optics, particularly focusing on the difference between their arrival time and the arrival time of light. We argue that, contrary to the observation in the previous work, gravitational waves never arrive at an observer earlier than light when both gravitational waves and light are emitted from a same source simultaneously.

TrissolcusAshmead (Hymenoptera: Scelionidae) is a cosmopolitan genus of egg-parasitoid wasps associated with stink bugs (Pentatomidae, Scutelleridae, Urostylididae), many of which are important insect pests. Documentation of host associations for these wasps, which we here provide via museum specimens, can support their use as biological control agents of invasive stink bugs.

The hosts of sevenTrissolcusspecies are reported from China:Trissolcus cultratus(Mayr) (hosts:Hippotiscus dorsalisStål, Pentatomidae;Urochela luteovariaDistant, Urostylididae),Trissolcus elasmuchae(Watanabe) (host:Niphe elongata(Dallas), Pentatomidae),Trissolcus japonicus(Ashmead) (hosts:Erthesina fullo(Thunberg), Pentatomidae;Rhaphigaster nebulosa(Poda), Pentatomidae),Trissolcus latisulcus(Crawford) (host:Poecilocoris latusDallas, Scutelleridae),Trissolcus mitsukurii(Ashmead) (host: Pentatomidae),Trissolcus semistriatus(Nees von Esenbeck) (host:Eurydemasp., Scutelleridae),Trissolcus yamagishiiRyu (host:Niphe elongata(Dallas), Pentatomidae).
