INFLUENCE OF WINTER WHEAT PLANTS’ FOLIAR ERTILIZATION ON CROP’S YIELD AND QUALITY

The article presents the results of experimental studies on the effect of foliar fertilization of winter wheat plants of sort Amandus with complex water-soluble fertilizers NAIS grain and Accelerator Micro on the background of N100Р58К100 on grain yield and quality. The research was conducted at Normagro LLC, Berdychiv district, Zhitomir region. The experiment included fertilizing winter wheat plants at the IV-V stages of crop organogenesis. The research was conducted on gray forest loamy soils. The use of these fertilizers proved to be quite effective. Compared with the background, the addition of conventional fertilizer with the studied fertilizers contributed to the increase in ear length and increase in the number of ears in the ear. The effect of using Акселератор Мікро was especially noticeable. The addition of background doses of fertilizers to the studied foliar fertilizers in our experiment affected the mass fraction of the crop, as evidenced by the data. At fertilizer N100P58K100 – received a crop – 6,08 t/ha, at N100P58K100 + «NAIS grain», 1,5 l/ha – productivity was 6,56 t/ha, at N100P58K100 + «Accelerator Micro» 1,5 kg/ha – 6,78 t/ha. In addition, the effect of combining the usual doses of fertilizers with foliar fertilization on the formation of the structure of the ear of wheat was studied. Among the studied parameters were the weight of one ear, the weight of 1000 grains, the nature of the grain. The weight of the ear with fertilizer N100R58K100 was –1,12 g, with N100R58K100 + «NAIS grain» (1,5 l/ha) – 1,17 g, and with N100P58K100 + «Accelerator Micro» (1,5 kg/ha) – 1,21 g, weight of 1000 grains – 42,3 g, 45,6 g, 48,9 g and nature of grain – 735 g/l, 745 g/l, 751 g/l respectively. The effect of the use of these fertilizers on the quality of the grain seed, in particular on the content of protein, gluten, ash and glassiness of the grain, was positive. A significant increase was obtained with the use of «Accelerator Micro», compared with «NAIS grain».

Особливості формування озерного фітопланктону

Вперше проведено дослідження фітопланктону озер Воронки, Луко, Острівське (Рівненська область), Дідове і водно-болотного угіддя Горохівка (Житомирська область). Ідентифіковано 161 вид водоростей, представлений 165 внутрішньовидовими таксонами з номенклатурним типом виду включно, що належать до 84 родів, 48 родин, 28 порядків і 13 класів. Встановлено, що у формуванні озерного фітопланктону провідну роль відіграють діатомові і зелені водорості. Кількість таксонів рангом нижче роду достовірно корелює з рН, кольоровістю і не залежить від площі озер. Виявлено тенденцію до посилення ролі дрібноклітинних центричних діатомових зі зростанням умісту фосфору фосфатів і загального азоту. Середнє значення діатомового коефіцієнта озер сягало 0,42.Встановлено помірну залежність інтенсивності вегетації водоростей від температури води, вмісту фосфору фосфатів. Найсильніший вплив на інтенсивність його вегетації має pH води, слабший – температура води, вміст фосфору фосфатів та загального азоту. В досліджуваних озерах провідна роль належить планктонно-бентосним і планктонним формам водоростей, індикаторам повільнотекучих і стоячих вод, помірним формам за відношенням до температури води, індиферентам за відношенням до солоності і рН. В озері Дідове і Горохівці відзначали помітну частку ацидофілів. Більшість видів-індикаторів сапробності представлена β-мезосапробами, олігосапробами, оліго- β-мезосапробами.Зі зростанням вмісту загального азоту частка олігосапробів знижується. В озерах переважає олігодомінантна структура фітопланктону. Зростання вмісту загального азоту зумовлює зниження його вирівненості.

As result of the study an abandoned quarry with no reclamation done and an illegal stone processing waste dump were found. It is stated that environmental impact of crystalline rock open cast mining not as serious as ilmenite or amber open cast mining impacts and facts of violation of law caused by mining activities were not found.

Young patients’ emotional expression peculiarities as a result of the military conflict in the East of Ukraine

For healthy personality formation process, early emotional experience is very important during very first years of children’s life. Nevertheless, fast urbanization, various anthropogenic processes, socially economic crisis, military conflicts and respective prolonged informational environment influences form young patients’ various emotional reaction changes. All of that negatively imprints young patients’ physical and psychological conditions, deteriorates their lives in social sphere and as a whole. Consequently, emotional expression peculiarities estimation provides us with an opportunity to analyze children’s actual psycho-emotional states and prognosticate their further development.
 The aim of this article: to identify emotional expression peculiarities for schoolchildren who live in various regions of Ukraine, from territorially close and distant areas during military conflict in the East of Ukraine.
 Research methods and procedures: our investigation has been carried out as a part of the research activity called “Development of medical psychological aid system for children and teenagers in the area of anti-terroristic operation” (state registration number 0116U004162). 100 preschool aged children from Donetsk region (group one) and 100 ones from Zhitomir region (group two) took part in our investigation. Research methods and methodologies: observation, conversation, various psycho-diagnostic procedures, obtained data statistic processing and analysis. Psycho-diagnostic complex: “Conga” (“Parovozick”) by S.V. Veliyeva, “Nonexistent Creature” by M.Z. Drukarevich, “Cactus” by O.M. Panfilova, “Fears Questioner” by A.I. Zakharova, “Stairways Test” by V.G. Shchur, “Family Picture” by G.T. Homentauskas, G.P. Lavrentyeva’s and T.M. Titarenko’s questioners on aggression and anxiety estimation (for young patients’ teachers and parents).
 Obtained results. Our research results examination is an evidence that the children who lives in Donetsk region suffer of various emotional disorders according to all investigated indexes. Significant difference between two groups of respondents has been discovered in the following: impulsiveness (45%), adult people aggression phobia (31%), anxiety (24%), desolation aiming (20%), emphasized asociality (21%), suspicion and with-draw behavior (20%) and aggression (14). Generally negative psycho-emotional state deterioration tendency has been discovered during our investigation irrespectively of the place of children residence. This phenomenon could be characterized by children’s excessive agitation and anxiety. These factors are usual in the situation of indefinite danger of some expecting event and reveal themselves as a negative prognosis for this situation completion.
 Resume: emotional disorders high rate in stress-producing environment is an evidence for some dynamic diagnostic system establishment necessity. Medical specialists (pedagogical workers, psychologists and general practitioners) activities regimentation is very important for young patients’ negative emotional states elimination and prophylactics. Consequently, complex and systematical activity of parents, psychologists, pedagogical and medical workers become actual nowadays.

The nature of the spread of porcine circovirus type 2 as an emerging in Ukraine during the period from 2007 to 2012

Pathogenic Porcine circovirus 2 (PCV-2) is a causal agent of many PCV‑2‑assocciated diseases of pigs, including porcine multisystemic wasting syndrome. Those diseases have a harmful effect by pigs’ production. Also, hotbeds of this infection are providing wide spread of this virus around the world. Ukraine is one of «hotspot» for PCV‑2‑assocciated infection, but has not enough information about distribution of this virus. Therefore, we have conducted a study to identify the causative agent of the mentioned disease. This article summarizes the results obtained by studying pathological material during the period from 2007 to 2012 by molecular diagnostics (PCR). Our results show that the distribution area for PCV-2 in Ukraine is mostly Ternopil’ (80 %), Kirovograd (60 %), Vinnitsa (57 %), and Dnipropetrovs’k (52 %) regions. It is less common in Kharkov (35 %), Cherkassy and Zaporizhya (both 27 %), and Lviv (33 %) regions. Nevertheless, some regions – like Zhitomir, Ivano-Frankivsk and Luhansk regions and Volyn’ – require a detailed study on the spread of the PCV-2

Activities concentration of radiocesium in wild mushroom collected in Ukraine 30 years after the Chernobyl power plant accident.

Mushrooms are recognized as one of the main contributors to internal radiation exposure from the activity concentration of radiocesium released by the accident at the Chernobyl nuclear power plant (CNNP). We evaluated the activity concentrations of the artificial radionuclides (radiocesium) in wild mushrooms collected in 2015 from Korosten and Lugine, Zhitomir region, Ukraine, located 120 km away from the CNPP. Cesium-137 was detected in 110 of 127 mushroom samples (86.6%). Based on the average mushroom consumption (5 kg per year), we calculated committed effective doses ranging from 0.001–0.12 mSv. Cesium-137 remains in the wild mushrooms even 30 years after the accident, but the committed effective doses are limited by the amount of contaminated mushrooms consumed. However, evaluation of internal radiation exposure and assessment of environmental radioactivity in the surrounding area affected by the nuclear accident are still necessary in order to relieve anxiety about internal radiation exposure, as long as the possibility of consumption of contaminated mushrooms remains.

First Record of the Late Eocene Ichneumon Fly Rasnitsynites tarsalis Kasparyan (Ichneumonidae, Townesitinae) in Ukraine Confirms Correlation of the Upper Eocene Lagerstätten

Rasnitsynites tarsalis Kasparyan (Ichneumonidae, Townesitinae) described from the Baltic amber is recorded for the first time in the Rovno amber (Gulyanka, Zhitomir Region); therefore, this is the southernmost and easternmost find of Townesitinae. The presence of numerous extinct taxa of Townesitinae and tribes of Hybrizoninae Blanchard 1845 = Paxylommatinae Forster, 1862 = Hybrizontinae Marshall, 1872 confirms close relation of the Bembridge Marls fauna (Upper Eocene of England) and that of the succinites (Baltic, Rovno, and other Late Eocene European ambers); they are common in the succinites and in the Bembridge Marls and are only known from these localities.

New Genus and Species of Gall Midges (Diptera, Cecidomyiidae, Porricondylinae, Holoneurini) from the Late Eocene Amber of Olevsk (Zhitomir Region, Ukraine)

Abstract Gall midges are reported for the first time in Late Eocene Rovno amber from the Olevsk, Zhitomir Region. This is the second amber locality to yield gall midges in the Zhitomir Region, after Gulyanka. Rovnoholoneurus gen. n. and two new species, Rovnoholoneurus davidi sp. n. and R. miyae sp. n. are described. Bryocrypta laqueata Fedotova, 2005 is transferred to the genus Rovnoholoneurus, and Rovnoholoneurus laqueatus (Fedotova, 2005), comb. n. is established. A key to the species of Rovnoholoneurus is provided.

Rovno Amber Caddisflies (Insecta, Trichoptera) from Different Localities, with Information about three New Sites

Abstract The inventory of the trichopterofaunas of all Rovno amber sites is provided for the first time. Syninclusions of all Rovno amber caddisflies determined to the species level are also listed for the first time. At least 29 named species are known in Klesov, as compared with only 21 species recorded in Bitterfeld amber. Eocene caddisflies are recorded in Belarus and Zhitomir Region for the first time, and new sites of inclusions are revealed as well: Rechitsa in Belarus, Olevsk in Zhitomir Region, Kuchotskaya Volia in Rivne Region. Rechitsa yielded Erotesis bessylenon Melnitsky et Ivanov, 2016, the first undoubtedly new Eocene taxon described from Belarus. This paper is also the first to involve the data on Danish amber caddisflies in comparison of the faunas. Only five genera from four families (Wormaldia McLachlan, 1865, Archaeotinodes Ulmer, 1912, Lype McLachlan, 1878, Holocentropus McLachlan, 1878, and Plectrocnemia Stephens, 1836) are known from four European Lagerstätten: Baltic, Bitterfeld, Danish and Rovno amber. Archaeotinodes igneusaper Melnitsky, 2009 is mentioned for Rovno amber for the first time. Genera Allotrichia McLachlan, 1880 (Hydroptilidae) and Palaeocrunoecia Ulmer, 1912 (Lepidostomatidae) are excluded from the Rovno amber fauna.

The definition of indices for bed stock optimization in medical institutions of hospital district

Introduction: Reformation of health protection sphere in Ukraine is impossible without optimization of stationary care with rational and open approach to estimation of the necessary bed stock what is particularly actually at hospital districts creation.Aim: to define factors of ungrounded hospitalization and possible decrease of treatment duration of patients who underwent stationary care in relevant departments.Methods: In research there were used 615 medical records of stationary patients (form 003/о) from Zhitomir region who finished their treatment in 2013. Medical documentation was selected by the way of total sample. At the first stage there was assessed the reasonableness of hospitalization in points from 0 (absolutely absent) to 5 (absolutely present). At the second one there was carried out retrospective analysis of patients medical records on optimal treatment duration by an expert assessment of medical records of patients whose hospitalization was grounded. Among 615 medical records that were used at the previous stage 399 were selected. On every medical record expert defined the number of days of the possible decrease of the hospital stay duration without an effect on patient’s state and final result of treatment.Results: On the results of first stage there were established that the mean index of ungrounded hospitalization was 35,1±1,9 %. On the results of second stage of research there were established that the mean duration of round-the-clock hospital departments stay was 8,25±0,98 days and was revealed a possibility to decrease this index by 0,70±0,02 bed-days.Conclusions: At hospital districts creation it is necessary to define indices of treatment duration and hospitalization reasonableness for patients in health protection institutions that are planned to be included to the one hospital district and to take it into account at calculation of profiles and number of beds

Evaluation of the Relationship between Current Internal 137Cs Exposure in Residents and Soil Contamination West of Chernobyl in Northern Ukraine.

After the Chernobyl Nuclear Power Plant accident, the residents living around the Chernobyl were revealed to have been internally exposed to 137Cs through the intake of contaminated local foods. To evaluate the current situation of internal 137Cs exposure and the relationship between the 137Cs soil contamination and internal exposure in residents, we investigated the 137Cs body burden in residents who were living in 10 selected cities from the northern part of the Zhitomir region, Ukraine, and collected soil samples from three family farms and wild forests of each city to measured 137Cs concentrations. The total number of study participants was 36,862, of which 68.9% of them were female. After 2010, the annual effective doses were less than 0.1 mSv in over 90% of the residents. The 137Cs body burden was significantly higher in autumn than other seasons (p < 0.001) and in residents living in more contaminated areas (p < 0.001). We also found a significant correlation between the proportion of residents in each city with an estimated annual exposure dose exceeding 0.1 mSv and 137Cs concentration of soil samples from family farms (r = 0.828, p = 0.003). In conclusion, more than 25 years after the Chernobyl accident, the internal exposure doses to residents living in contaminated areas of northern Ukraine is limited but still related to 137Cs soil contamination. Furthermore, the consumption of local foods is considered to be the cause of internal exposure.

New gall midges (Diptera, Cecidomyiidae, Stomatosematidi, Brachineuridi) from the Late Eocene amber of Gulyanka (Zhitomir Region, Ukraine)

Gall midges and insects in general are recorded for the first time in the Late Eocene Rovno amber from Gulyanka, Zhitomir Region. The specimens described are the first named Late Eocene amber insects collected east of Klesov. One new genus and two new species, Rovnodidactylomyia zhitomirensis sp. nov. and Gulyankiola nazarenkoi gen. et sp. nov., are described. The diagnosis of the genus Rovnodidactylomyia, which includes six species known from the Late Eocene Baltic and Rovno ambers, is emended.

Experience of study of the incidence of malignant neoplasms population in small areas of Ukraine, which suffered contamination with radionuclides due to the Chornobyl accident

to evaluate the dynamics of implementation risks of malignant tumors in some small areas of Ukraine in the pre- and post-accident period. The study population group - the population of the Malyn rayon, Zhytomyr region. The period of observation covered 1980-2014. There was investigated the incidence of malignant tumors in general and individual nosological forms (thyroid cancer, breast cancer, tumors of hematopoietic and lymphoid system). Methods of variation statistics and descriptive epidemiology were used. Characteristics of ionizing radiation influence on the population of Malyn rayon indicate the potential for negative effects, especially for thyroid cancer. Besides the fact that the average total effective radiation dose whole body by radioactive cesium in Malyn rayon population (5.9 mSv) are at medium level in Zhytomyr region and is significantly lower in comparison with those of other areas of the northern part of the oblast, the exposure of thyroid 236 mGy, is significantly higher than the regional figures - 81 mGy. Although the level of morbidity Malyn rayon of malignant tumors in general was about at the national level for 1999-2003 and lower it in the 2012-2014, exceeding the figures of Zhytomyr region, the incidence of thyroid cancer in the 2012-2014 in Malin area was 1.7 times higher in comparison with data for Ukraine and in 1.9 times in comparison with the data in Zhytomyr region. As in most northern areas that fell under radioactive iodine fallouts, there is the realization of increased radiation risk of cancer of this organ. The incidence of breast cancer in female population Malyn rayon is the lowest in comparison with Ukraine and Zhitomir regions. However, the rate of increase in this area is the highest. The results indicate the need for further monitoring of occurrence of cancer cases in the population of not only Ukraine as a whole, or large administrative units, but also among the population in small areas, taking into account the probability of the realization of risks of radiation-associated disease cases according to local environmental conditions.

Prognosis of Thyroid Nodules in Individuals Living in the Zhitomir Region of Ukraine

ObjectiveAfter the accident at the Chernobyl Nuclear Power Plant (CNPP), the incidence of thyroid cancer increased among children. Recently, a strong relationship between solid thyroid nodules and the incidence of thyroid cancer was shown in atomic bomb survivors. To assess the prognosis of benign thyroid nodules in individuals living in the Zhitomir region of Ukraine, around the CNPP, we conducted a follow-up investigation of screening data from 1991 to 2000 in the Ukraine.Patients and MethodsParticipants of this study were 160 inhabitants with thyroid nodules (nodule group) and 160 inhabitants without thyroid nodules (normal control group) intially identified by ultrasonography from 1991 to 2000. All participants were aged 0 to 10 years old and lived in the same area at the time of the accident. We performed follow-up screening of participants and assessed thyroid nodules by fine needle aspiration biopsy.ResultsAmong the nodule group participants, the number and size of nodules were significantly increased at the follow-up screening compared with the initial screening. No thyroid nodules were observed among the normal control group participants. The prevalence of thyroid abnormality, especially nodules that could be cancerous (malignant or suspicious by fine needle aspiration biopsy), was 7.5% in the nodule group and 0% in the normal control group (P<0.001).ConclusionsOur study indicated that a thyroid nodule in childhood is a prognostic factor associated with an increase in the number and size of nodules in individuals living in the Zhitomir region of Ukraine.

ОСОБЛИВОСТІ ГНІЗДОВОЇ ЕКОЛОГІЇ ПОПУЛЯЦІЙ СІРИХ ВОРОН (CORVUS CORNIX L.) В УМОВАХ ТРАНСФОРМОВАНИХ ЛАНДШАФТІВ

&lt;p&gt;The comparative analysis of hooded crow breeding ecology was performed for Zhitomir region in 2010-2011 in terms of rural and urban distinctions. Height of trees, tree species diversity in breeding biotopes, nest size, and breeding success of hooded crows were considered for agricultural and urban landscapes. Definite patterns of breeding ecology were estimated for urban and rural populations of hooded crows. On average, the breeding density of hooded crows was 7-8 individuals/km&lt;sup&gt;2&lt;/sup&gt; in Zhitomir region.&lt;/p&gt; &lt;p&gt;Positive correlation was found between the breeding density of hooded crows and degree of transformation and urbanization of landscape of Zhytomyr region. The main breeding habitats of hooded crows in the Zhitomir region were the wetland sites. Communities of urban birds were characterized by earlier terms of nest building, more higher position of nests in the trees and high diversity of tree breeding habitats. In urbanized landscape we determined high proportion of large (6 eggs) and small clutches of hooded crow (3 eggs).&lt;/p&gt; &lt;p&gt;On average the breeding success of crows in Zhytomyr region is 51.1%. We suggested that the main factor was high level of elimination of embryos and chicks of hooded crow. In urbanized landscapes the breeding success (50%) is somewhat higher than that in rural areas (43.5%). This can be explained by specific features of ecological niches - in cities the bird communities have few natural predators that kill chicks and destroy clutches, and potentially have more available food resources.&lt;/p&gt; &lt;p&gt;&lt;em&gt;Kew words: hooded crow, breeding ecology, Zhitomir region, comparative analysis&lt;/em&gt;&lt;/p&gt;
