Определен видовой состав крестоцветных блошек в Рязанской области. Проведен подбор препаратов для защиты рапса ярового от крестоцветных блошек. Для этого применен системный подход к изучению воздействия пестицидов на вредителя. Представлена сравнительная эффективность препаратов разной химической природы, предназначенных для борьбы с крестоцветными блошками на рапсе яровом. Установлен видовой состав фитофагов в агроценозе рапса в условиях региона. Исследованиями подтверждено, что протравливание семян необходимый прием в агротехнологии, в том числе на рапсе в борьбе с крестоцветными блошками. В исследованиях выявлено, что наиболее эффективными против комплекса крестоцветных блошек являются протравители Круйзер Рапс, КС и Модесто, КС. Их применение позволило снизить численность крестоцветных блошек в 2,5 раза по сравнению с контролем и получить максимальную в среднем за три года прибавку урожая (40,5) за счет приемлемого уровня подавления популяций вредителей и продолжительности действия. Предложено для защиты всходов рапса от крестоцветных блошек рекомендовать к широкому внедрению в производство протравители семян типа Круйзер Рапс, КС и Модесто, КС. Такие препараты подавляют вредителей до уровня ниже экономического порога вредоносности, обеспечивают существенную прибавку урожая, оказывают минимальное негативное влияние на нецелевые организмы агроценоза, их применение исключает проведение дополнительной инсектицидной обработки.The species composition of cruciferous fleas in the Ryazan region was determined. The selection of preparations for the protection of spring rape from cruciferous fleas was carried out. For this, a systematic approach to the study of the effects of pesticides on the pest was applied. Comparative effectiveness of preparations of different chemical nature intended for controlling cruciferous flea on spring rape is provided. The species composition of phytophages in the rape agrocenosis in the region has been established. Studies have confirmed that seed dressing is a necessary technique in agricultural technology, including canola in the fight against cruciferous flea. The studies revealed that the most effective against the cruciferous flea complex are the protectants Kruiser Rape, KS and Modesto, KS. Their use made it possible to reduce the number of cruciferous fleas by 2.5 times in comparison with the control and to obtain the maximum yield increase on average over three years (40.5) due to an acceptable level of suppression of pest populations and duration of action. It is proposed to protect seedlings of rapeseed against cruciferous fleas that seed dressers such as Kruiser Rapeseed, KS and Modesto, KS should be widely introduced into production. Such drugs suppress pests to a level below the economic threshold of harmfulness, provide a significant increase in yield, have a minimal negative effect on non-target organisms of agrocenosis, their use excludes additional insecticidal treatment.

Toxicity and hazard assessment of dioctyl terephthalate (DOTP) was performed in acute, subacute, and chronic experiments, and its principal toxicometry parameters were determined.It was found that on single exposure DOTP exhibits low toxicity and hazard. No resorptive and irritant effects on skin and mucous membrane of eyes were detected in animal experiments. The single inhalation exposure threshold limit value was set at 300 mg/m3, based on the results of monitoring of the functional state of the central nervous system and myocardium and hematological parameters.Thirty-day subacute experiments (oral administration, inhalation exposure, and skin applications) revealed no accumulation of the compound.Four-month chronic exposure to DOTP aerosols (concentration 96,8 mg/m3) caused disorder of the functional state of the central nervous system and myocardium, changes in the hematological and biochemical parameters, gas and acid-base status of the blood, and morphological changes in the lungs and heart. Embryotoxic, genotoxic and gonadotoxic effects were not detected.The chronic inhalation exposure threshold limit value for DOTP (Limch) was set at 18,6 mg/m3, and the concentration of 3,4 mg/m3 was found to be ineffective.The maximum allowable concentration of DOTP in the air of the working area was set at 3,0 mg/m3, hazard class 3.
IMMUNOTROPIC EFFECTS OF IVERMECTIN IN PRODUCTIVE AND LABORATORY ANIMALS
Authors: Gerunov T. V. 
Published: February 2020

The aim of this work was to identify the immunotropic effects of ivermectin in productive and laboratory animals in real and simulated conditions. The studies were carried out on hybrid pigs at the age of 144 days reared in an industrial pig complex and on Wistar rats aged 5 months with a body weight of 230 - 250 g. For the experiments there was used acaricide insecticide Ivermin (Biovet Drwalew S.A., Poland), which was administered to pigs once subcutaneously in a dose of 0,2 mg / kg and to rats in a tenfold therapeutic dose. Blood samples were taken from pigs either before the administration of Ivermin, and 1, 3, 7, 14 and 30 days after the administration. The level of immunoglobulins (IgG, IgM, IgA) was determined in serum by the method of radial immunodiffusion according to Mancini. To prepare histopreparations, samples of thymus, spleen and lymph nodes were taken from rats 14 days after the administration of the preparation. For statistical processing of experimental data, Student’s T-test for dependent samples has been used.When studying pigs’ blood serum, a decrease in the content of IgG was established in all periods of the study. A decrease in level of IgM and IgA was marked in 7 days after the experiment started. At the end of the experiment, the IgG level remained below the background value by 16,4%; IgM - by 15,2%; IgA – by 33%. In the rat thymus, a narrowing of the cortical substance was observed when a toxic dose of Ivermin was injected, with the splenic follicles reduced, and reproduction centers faintly pronounced. Hemosiderin accumulation was detected around the follicles. In the mesenteric lymph nodes, there was found a thickening of the capsule and the expansion of trabeculae. Cortical substance was narrow and paracortical zone was wide. The results of the study indicate a high risk of immunotoxic effect of ivermectin.
Reflexión, diálogo y comprensión: tres principios integrales de la evaluación educativa
Authors: Muñoz Flores Wilson Gonzalo 
Published: February 2020

La educación del siglo XX ha sido un proceso de contradicciones. Ofrece desafíos y oportunidades, donde los símbolos de la libertad son los que han sostenido los tres principios sociales de la educación que deben estar presentes en nuestras aulas contemporáneas y mantener vigencia en la cultura educativa nacional: reflexión, diálogo democrático y comprensión (Santos Guerra, 1998).
Bien sabemos los educadores modernos que estos tres principios sociales atraviesan el proceso de enseñanza-aprendizaje y desarrollo contextualizándolo con todos aquellos elementos propios del sistema educativo: docentes, alumnos, padres, apoderados, contenidos, objetivos, estrategias y evaluación. Esta última es la que valida consciente, reflexiva y dialógicamente el proceso, entendido éste como una significación, una mejora y una apropiación del real sentido del aprender y del reaprender en el aula. Es una comprensión de las posibilidades y los desafíos que el sistema entrega a quienes participan en el desarrollo del curriculum.
Uso y actitudes hacia las TIC en docentes de matemáticas y su relación con el logro académico de sus estudiantes
Authors: Lomprey Gerald , Del Valle López Jair A. 
Published: February 2020

Esta investigación buscó conocer la correlación entre el uso y la actitud del docente de matemáticas hacia las TIC y el rendimiento académico de sus estudiantes.
El estudio se llevó a cabo con 203 estudiantes y 10 docentes de todas las escuelas del tercer año de secundaria del municipio de Montemorelos, Nuevo León, México. El diseño metodológico de este estudio es (a) cuantitativo, (b) ex post facto, (c) transversal y (d) correlacional.
Los resultados estadísticos de esta investigación confirmaron la existencia de una correlación (r = .610) positiva media entre la variable independiente uso de las TIC por parte del docente y la variable dependiente logro académico de los estudiantes. Basándose en los resultados de esta investigación, se deduce que los estudiantes pueden tener un mejor logro académico si los docentes hacen un mejor uso de las TIC. Por otro lado, las variables actitud del docente y uso de las TIC por parte del estudiante no incidieron en el logro académico en matemáticas del estudiante.

El estudio, de tipo cuasi experimental, siguió un diseño de preprueba posprueba con grupo experimental y grupo de control. Si bien no se observaron efectos significativos de la incursión en ambientes de aprendizaje con uso de tecnología en el desarrollo de habilidades intelectuales, una diferencia mínima en el tamaño del efecto mantiene la suposición al respecto. Las valoraciones positivas en cuanto a la introducción de las tecnologías de la información y de la comunicación en la enseñanza incentivan la continuación de esta primera experiencia.
YAGORLYK KURGANS OF THE LEFT BANK OF THE DNIESTER: HISTORY OF EXPLORATION, CARTOGRAPHY AND TOPOGRAPHY
Authors: Sаpоzhnykov I. V. , Boltryk Yi. V. 
Published: February 2020

The article is devoted to the kurgans which are located on the 45 km long cape, formed by the valleys of the Yagorlyk and Sukhyi Yagorlyk rivers, which merge at the left bank of the Dniester. These burial mounds were mentioned and even painted by J. A. Münz (1781), and then described and put on cards by A. K. Meyer and F. P. de Volan (1791).
Topographers and archaeologists have noted up to 120 mounds reaching a height of 8—9 m in this local region. Most of them are stretched along the top of the watershed, some groups stand with two parallel lines, a number of chains of kurgans are oriented across the watershed. In general, they mark the site of the ancient trade route, along which it was possible to travel from the Dniester to the north to the forest-steppe; to the east to the Dnipro region and to the south-east to the Danube delta and the Black Sea.
PENDULUM MIGRATIONS IN THE CIRCUM-PONTIC STEPPE AND CENTRAL EUROPE DURING THE PALEOMETAL EPOCH AND THE PROBLEM OF GENESIS OF THE YAMNA CULTURE
Authors: Ivanova S. V. , Nikitin A. G. , Kiosak D. V. 
Published: February 2020

This article is dedicated to the problem of the origin and spread of the Yamna cultural-historical community (YCHC) in the context of the hypothesis recently expressed by geneticists about the massive migration of population groups genetically related to YCHC and carrying the genetic determinants of the Iranian Neolithic agrarians and hunters and fishers of the North Caucasus from the Ponto- Caspian steppe to central and northern Europe at the beginning of the Bronze Age. Based on an in-depth archeological and genetic analysis, we propose that the genetic «invasion» of the Iranian-Caucasian genetic element into Europe at the beginning of the Bronze Age, recently proposed by paleogenetisits on the basis of a large-scale study of ancient DNA, was not the result of a large-scale migration of representatives of YCHC from the Ponto-Caspian steppes to central and northern Europe, but the result of global population and cultural changes in Eurasia at the end of the Atlantic climatic optimum. We further suggest that before the steppe genetics appeared in Europe at the beginning of the Bronze Age, central European genetic determinants appeared in the steppe in the Eneolithic, and that the movement of the steppe genetic element to Europe was at least in part the second phase of the «pendular» migration of European expatriates, returning to the historical zone of habitation. We also come to the conclusion that the very concept of distinguishing YCHC as a monolithic entity is inappropriate, and that the groups of nomadic tribes of the Ponto-Caspian steppe most likely existed as discrete communities, although united by a common ideology and a genetic relationship that included both the Iranian-Caucasian (throughout the entire range), and European / Anatolian agricultural (locally) genetic elements.
THE ANCIENT DEFENSIVE FORTIFICATIONS OF DANUBE WAFTAGE NEAR KARTAL LAKE
Authors: Dzygovskiy A. N. , Sapozhnikov I. V. 
Published: February 2020

The article is dedicated to the characteristics of the defense constructions in the area of river crossing of Danube near lake Kartal not far from village Orlovka of Reny district in Odessa region and their historical interpretation. The conclusion was made, that in this district in the first ages AD. the powerful defensive center functioned, created by Romans. In the center’s system there were Romans fortifications on the sites near the villages Orlovka and Novoselskoye altogether with the ramparts and graffs, which surrounded them, and also one more rampart, which was situated between those two fortificated points. The last one featured the rampart-road and was the important component of this defensive center. Romans started the creation of Kartal defensive center in the 60s years AD. and continued its organization during Vespasian’s regiment term. The center finished its functioning near the middle of the III century AD.
As regards the fortificated area, situated between the left shore of lake Kagul and the right shore of lake Yalpug, according to the written sources’ information about the war events, which had taken place in Southern Budzhak in ancient times and considering the density of population of this part in the time of discussing events, we can suppose, the fortificated area may be built by Scythians in the last third of the IV century BC or by Goths in the last third of the IV century AD.
LOCALIZATION OF THE «PEREYASLAV — VOYIN» PART OF THE DNIEPER TRADE PATH BY THE SETTLEMENTS’ LOCATION
Authors: Pryadko O. О. 
Published: February 2020

The article is devoted to the part of the Dnieper trade path’s localization by the location of fortifications at the crossings through the steppe riversin the micro region. It was impossible to prove this version earlier due to the lack of known settlements along the path. As a result of the exploration conducted in 2012—2017 there were discovered previously unknown fortifications in Pishchane, Kropyvna and Irkliiv. Thus it is became possible to precisely position the fords and crossings that covered those settlements. Above mentioned network of fortifications functioned from the middle of the XII to the first half of the XIII century. This is confirmed by the materials found.
ARCHAEOLOGICAL MARKERS OF THE SOUTHERN SECTION OF THE MURAVSKY SHLYAH
Authors: Elnikov M. V. 
Published: February 2020

Muravsky Shlyah from the XVI century was one of the known routes of communication in the steppe region of the Left Bank of Ukraine. This important transport strategic highway was used both for military and commercial purposes. Reconstruction of the southern section of the Muravsky Shlyah «in a large semicircle», according to the «Kniga Bolshomu Chertezhu» — the tops of the rivers from Orel to Molochnaya, exclude its passage through water crossings. Analysis of a number of written sources and cartographic material of the XVII — early XX centuries, with the indication of «mosques» — archaeological markers on the «Orekhov route», allowed to draw a conclusion about the route of this steppe way through fords. At the river crossings, on the banks of the rivers Volchy, Кonsky and Ovecy Vody, ambassadorial missions, military and travelers fix the remains of «mosques» — hillforts period of the Golden Horde. In this region the trade routes crossed, including the Great Silk Road in the XIV century, which were of great strategic importance for a long time, — before the advent of the railway. Localization of the monuments of the Golden Horde period on this communication allows you to raise the question of its occurrence at an earlier time.

Authors: Puklina O. O. 
Published: February 2020

Among numerous shapes of Ancient Greek glass drinking vessels from the Northern Black Sea Coast, the group of bowls-phials with engraved and polished ornamentation (2nd—3rd centuries AD) could be distinguished. The fragments of mentioned vessels, which were found on the territory of Roman garrison in Olbia and stored in the Scientific Repository of the Institute of Archaeology NASU, are examined in this research. In addition, the technological process of their manufacturing is closely analysed. Wide distribution and active application of phials concurred with intensification of trading communications and economic advancement of the period from the second half of the 2nd century AD to the first half of the 3rd century AD and the Roman garrison’s residence in Olbia.
MEDICAL INSTRUMENTS FROM THE SCYTHIAN KURGANS OF KHERSON REGION (a New Look at Famous Artefacts)
Authors: Fialko O. Ye. , Homchyk M. A. , But Yu. P. 
Published: February 2020

In 1973, the Kherson Expedition of the Institute of Archaeology of Ukraine under the leadership of A. I. Terenozhkin discovered a group of kurgans near the village of Lvove in the Kherson region. Five Scythian graves were investigated in the mound 11. Two of them belonged to the Amazons and have not been robbed.
Some of the items from these kurgans are stored in the National Museum of Ukrainian History. After the restoration, they in fact have got a second life and a new attribution. The most interesting are things from burial 2: a pair of iron spring forceps, an iron knife with a bone faceted handle, and a bronze bowl. According to the Doctor of Veterinary O. P. Melnyk, these items are close to modern medical instruments. The bronze bowl with thin sides, a flat bottom and a corolla with a rigid ledge could serve for fast heating of water and sterilization of tools. Iron forceps could be used to take tools out of boiling water. The shape of the knife blade and its technological features are similar to modern hoof knives designed to care for the hooves of animals. A similar bowl was found in burial No. 4, while another bowl and a bronze knife were in the main burial 7 of the same kurgan.
Moreover, the collection of the Museum contains a series of iron knives from kurgans near Pervomaivka village in Kherson region. Their design features, according to Professor O. P. Melnyk, allow us to see in them medical instruments. One of them by the shape of its blade resembles a modern scalpel.
Judging by pieces of art, healing and zootechnics have reached a high level among the Scythians. Significant examples in this respect are the metal bowl from the kurgan Kul-Oba and the amphora from the kurgan Chortomlyk. The scene of the castration of a horse is depicted on an amphora. As reported by Strabo, the Scythians had a common practice to castrate horses, and the Amazons have been taking care of their horses on their own. Consequently, it is quite possibly that the Amazons carried out certain veterinary operations. In addition to castration, an equally important operation in horse breeding is the cleansing of hooves.
The considered artefacts served as tools that could be used both in medicine, and in veterinary medicine. Thereby we can make a conclusion that the Scythian Amazons did not concede to men in medical practice as well.
SINGLE-EDGED DAGGER OF THE 4TH CENTURY BC FROM THE LOWER DNIPRO REGION
Authors: Shelekhan O. V. 
Published: February 2020

In presented article, Scythian barrow with original single-edged dagger is published. This burial is characterized as typical Scythian complex. It was arranged in the catacomb with stone overlap. A buried man was placed with his head to the west, with the dagger near his left hand. This dagger has bright decoration. There were bone plates on the hilt, fixed by three iron rivets with wide heads. Known analogies belong to the horizon of the 5th—4th centuries BC and are associated with impacts from the cultures of the Northern Balkans. Some arrowheads, remained after the robbery, give as possibility to establish the date of this complex more particularly by the middle 4th centuryBC.
OLBIAN TERRACOTTA BUSTS WITH HANDMADE CUPS AND ADORNMENTS
Authors: Shevchenko T. M. 
Published: February 2020

Analysed is a series of bust thymiateria with handmade details: stephanes, earrings, and buttons fastening chiton on shoulders. Handmade cups on their heads were not the headdress, but the functional details, and were probably used in some rituals as containers for incenses. A detailed analysis shows that several of them were produced in a single mould, two items produced not in Olbia, and on some of them tainia on the personage’s head were shown already in a mould. It is traced that the busts are close to Olbian semi-figures of bigger size with more elaborate, though also handmade, adorations. Stylistically, this group can be dated by the first half of the 3rd century BC. Almost all of them come from the excavations at dwelling quarters and were probably used in family cults. They were often found with other terracottas’ fragments, namely, with images of the Mother of the Gods and Dionysus.
These busts belong to one of several groups of Hellenistic thymiateria. They are the least definite for attribution. Personages of other groups present the reliable features of their relation to the cults of the Mother of the Gods, Aphrodite, and Dionysus. Similar thymiateria from other Ancient Greek centres represent images of the same circle of the gods. Here, an attention to decorations and the clothes can only indirectly indicate for an image of Aphrodite or a participant of her cult, while spherical adornments attached most often to the temples, together with tainia on the heads of several items, can be hypothetically a part of a wreath made of ivy fruits, as on the heads of Dionysiac characters. Consequently, there are no reliable grounds yet for a definite attribution of these thymiateria’s images. There are also no grounds to see Demeter or Kore-Persephone in them. The study of other groups of Olbian busts-thymiateria is perspective for the further attribution.
