Producción de Soya Transgénica y Miel en Yucatán, México. Impactos en la Sustentabilidad de Productores en Tekax
Authors: Rivera de la Rosa Alba Rosa , Ortiz Pech Rafael
Published: April 2020

La producción de soya en México se inserta dentro de las tendencias globales de las cadenas de valor cereales-carne en el tercer régimen alimentario. La soya transgénica se introduce en México a principios del siglo XXI y una de las consecuencias medio ambientales más cuestionadas de su producción es el uso intensivo del herbicida a base de glifosato, con graves consecuencias para la salud humana y medio ambiente. Los efectos de la producción de soya se dejan sentir en productores mecanizados de la zona de Tekax, Yucatán, afectando la selva primaria, los mantos freáticos y otras actividades que dependen de la biodiversidad de la región como la producción de miel, de la cual el estado de Yucatán es el primer productor en México. El objetivo del presente trabajo es conocer las condiciones de producción económicas, medio ambientales y algunas de tipo social, de los productores de soya en el municipio de Tekax, Yucatán, México; lugar donde se introdujo por primera vez la producción de soya transgénica. En segundo lugar, se busca conocer el impacto de los cultivos agrointensivos como la soya, en la producción de miel en Tekax, ya que ambas actividades conviven en un mismo espacio territorial. Los resultados arrojan un alto nivel de contaminación en la producción de soya y un impacto positivo de los cultivos agrointensivos en la producción de miel.
El Rol de las Exportaciones en el Crecimiento Económico: Evidencia de una Muestra de Países de América Latina y el Caribe
Authors: Toledo Wilfredo
Published: April 2020

Se estudia la hipótesis del crecimiento económico fomentado por las exportaciones. Dicha hipótesis se examina en un panel de datos de 17 países de América Latina y el Caribe para el periodo de 1971 a 2013. La principal metodología que se utiliza es la prueba de causalidad de Granger. El análisis se realizó para las exportaciones totales y las de productos de alta tecnología. Se encontró una relación de retroalimentación entre el PIB real y las exportaciones totales, por lo que no existe evidencia para la hipótesis mencionada. Sin embargo, los resultados evidencian una relación unidireccional débil de las exportaciones de alta tecnología a la producción agregada real.

Possibilities of mathematical definition of unfavourable course of subarachnoid haemorrhage in the acute period
Authors: Polkovnikova K. Y.
Published: April 2020

Subarachnoid haemorrhage (SAH) is associated with a 30-day mortality rate of 50% and is one of the most life-threatening cerebrovascular diseases.

Objective. Toevaluatetheprognosticsignificance and informativeness of some clinical indicators, highlighting the most optimal and reliable potential factors in the development of a mathematical equation for calculating the personal probability of complications in patients with subarachnoid hemorrhage of atraumatic etiology.

Materials and methods. A clinical experimental study involved 87 patients with SAH, 44 were men, 43 – women. On the first day after SAH, half of the patients were hospitalized – 46 people (52,87%).

Results. The constructed model for calculating the probability of events such as secondary ischemia, hydrocephalus, or cerebral vasospasm over the next 14 days indicates the correctness and adequacy of the constructed model of logistic regression.

The personal probability of a complication is calculated by the formula: p = 1 / (1 + e-z), where p is the % probability of a complication of SAH; z = –45,5 + 17,5* Copeptine –0.44 × Na + 0,06 × Age + 1,99 × Ball (Hunt-Hess).

Conclusions. The prognostic model allows us to consider that secondary ischemia and cerebral vasospasm are not only predictors of poor prognosis and potential factors for the formation of complications, but also are indicators for the correct determination of individual cumulative risk in SAH.

Published: April 2020

Purpose of the study. To study the balance of fatty acid spectrum of oral lipids as a marker of oxidant-antioxidant stress in patients with generalized parodontitis with anorexia nervosa.

Materials and methods. The study metabolic disorders of fatty acids oral fluid was conducted in 28 patients with GP, primary-I, I–II degree, chronic course associated with anorexia nervosa, (average age 26 ± 3,8) – the main group (M). The comparison group (C) included 23 patients with GP, primary-I, I–II degree, chronic course with no eating disorders. The control group consisted of 25 healthy individuals of the same age category. Patients' oral fluid was used as the object of study. In the spectrum of fatty acids of lipids of the oral fluid, the 9 most informative fatty acids were identified: myristic C 14:0,

pentodecane C 15:0, palmitic C 16:0, margarine C 17:0, stearic C 18:0, oleic C 18:1, linoleum C 18:2, linolen C 18:3, arachidone C 20:4. Quantification of the spectrum of lipid fatty acids was performed by the method of normalization of planes and determined the proportion of acids in percents.

Results. The fatty acid content of the oral fluid of patients in the main group was significantly different from the control parameters. 12% in patients with anorexia nervosa significantly increased the amount of saturated fatty acids by increasing the content of palmitic acid (C 16 0) and reducing stearic acid (C 18:0) by 2 times compared with control.

It was established that the sum of unsaturated fatty acids was reduced by 2 times due to polyunsaturated fatty acids, and this level was significantly reduced by 2 times in comparison with control group due to 3 times reduction of linoleum fatty acid (C 18:2), linolenic fatty acid (C 18:3) 2-fold and unreliable increase in arachidone fatty acid (C 20:4), in comparison with the control, which in our opinion, reflects disturbance of the oxidant-antioxidant balance and is a marker of stress as an indicator of endogenous intoxication in patients with GP and anorexia nervosa.

In patients with generalized parodontitis of primary-I, I–II degree, chronic course of anorexia nervosa in the oral fluid there was a significant violation of lipid metabolism – increase in the content of palmitic fatty acid (C 16:0) and decrease in the content of linoleic fatty acid (C 18:2).

Conclusions. The revealed features of the course of GP in patients with anorexia nervosa indicate the need for additional treatment and prophylactic measures in this group of patients. Disorders of the fatty acid spectrum of the oral fluid in these patients were necessitate the inclusion in the traditional scheme of treatment of GP aimed at correcting the processes of antioxidant protection, which increase the effectiveness of therapeutic and prophylactic effects.
Melanoma of nasal cavity. Literature review and clinical case report
Authors: Krasovskaya N. Y. , Meleshkina I. V. , Kashirin V. A.
Published: April 2020

Primary malignant melanoma of the nose mucosa is a rare disease and seen in less than 0,5–0,7% among all melanomas, but has a worse prognosis because of its aggressiveness compared with that of the cutaneous form. Most of the nasal melanomas are not detected in early stage and survival statistics have not improved over the last years. The incisional biopsy is contraindicated, as this may increase metastatic spread. Cytology is definitely a simpler and safer method of getting a quick diagnosis.

Most melanomas of nasal mucosa were found when infiltrating muscle, cartilage, or bone, that's why craniofacial resection remains the «gold standard» for these tumors, but and endoscopic resection of sinonasal mucosal melanoma (at limited tumors) has comparable outcomes to open approaches.

In report review the relevant medical literature (clinic, classification, histology, treatment and survival) and case observation of patient with primary nasal malignant melanoma.
Relationships between markers of extracellular matrix degradation and systemic inflammatory response among patients with acute myocardial infarction
Authors: Sid E. V. , Litvinenko V. V.
Published: April 2020

Despite all the preventive, diagnostic and therapeutic possibilities of our time, diseases of the circulatory system are the leading causes of death among adult population both in the world and in Ukraine. Modern consensuses of the European society of Cardiology have recommendations with many years of based-on-evidence experience in the diagnosis of acute myocardial infarction. They note that biomarkers of myocardial necrosis must meet modern requirements of accuracy, reproducibility, and especially sensitivity and specificity. Now, together with classical markers of heart muscle damage, markers reflecting various pathogenetic directions of acute myocardial infarction are increasingly used in clinical practice; they include markers of myocardial dysfunction and markers of inflammatory process activation.

Purpose of the study. Identify relationships between markers of the extracellular matrix degradation and systemic inflammatory response among patients with acute myocardial infarction. Materials and methods. Results of the study are based on data from a comprehensive survey of 305 IHD patients: 162 patients with STEMI, 81 individuals with NSTEMI, and the control group consisted of 62 patients with angina pectoris (functional class II and III for 31 people). The sample of patients was carried out in the period from 2015 to January 2018 on the basis of MI «Regional medical center of cardiovascular diseases» of the Zaporizhzhia regional Council. All 305 surveyed people were comparable in age, social status, and gender (with the ratio of men to women was 4 to 1).

Results and discussion. The highest level of HS-CRP was in the group of STEMI patients and amounted to 10,91 (9,40–13,43) mg/l and significantly exceeded by 24% the level of this indicator in the group of NSTEMI patients – 8,80 (7,05–10,91) mg/l, (p < 0,05). The level of TNF-αwas significantly higher in the STEMI group of 2,10 (1,53–2,86) pg/ml versus 1,67 (1,09–2,20) pg/ml in the NSTEMI group of patients, (p < 0,05) and the leap rate was 2,4 times higher than the level of 0,89 (0,67–1,55) pg/ml in the group of patients with stable IHD (p < 0,05). In both groups of AMI patients with both STEMI and NSTEMI, there was a significant increase in IL-6 levels compared to the group of patients with stable IHD, where this indicator was 2,26 (1,22–3,66) pg/ml, 5 and 3,2 times, respectively (p < 0,05). The IL-6/IL-10 ratio in the STEMI and NSTEMI groups was 2,78 (1,72–4,68) versus 1,82 (1,49–2,36), respectively, and was significantly 50,8% higher (p < 0,05). Reliable direct links were found between: the levels of MPP-9 and HF-CRP (R = +0,61, p = 0,001), the levels of MPP-9 and TNF-α (R = +0,62, p = 0,001), the level of MPP-9 and the IL-6/IL-10 ratio, the levels of TIMP-2 and CRP (R = +0,50, p = 0,001).

Authors: Leliuk D. V.
Published: April 2020

Purpose of the study. Improve the outcomes of treatment for uncomplicated hypertensive crises at the prehospital stage by studying the state of systemic hemodynamic, determining the balance of the autonomic nervous system and markers associated with the systemic inflammatory response in arterial hypertension patients in uncomplicated cases of hypertensive crisis.

Materials and methods. During the 2017–2019 period, an open, prospective and comparative study was conducted and consisted of 206 patients with documented second-stage hypertension, of which 131 patients sought emergency medical attention in the «Municipal Institution Zaporizhzhya Station of Emergency (Ambulance) Medical Assistance» and 75 people who had a stable course of the disease and were examined on an out patiently on the basis of the

«Primary health care Centre No 10». Practically healthy 31 people were examined on the basis of the MI «Regional medical exercises dispensary». The indices of heart rate variability in the examined persons were analyzed. All patients were examined physically, used generally clinical, instrumental and laboratory methods for ECG diagnosis were recorded according to the standard method, on a 12-channel computer-cardiographic complex

«Cardiolab» (KhAI-Medika, Kharkov). The examinations were performed before the start of emergency care and after HC relief. For the analysis of heart rate variability, a 5-minute ECG interval recorded at rest was used, and the signal was recorded in the supine position, with calm breathing. The obtained data were analyzed with the help of the Cardiolab-HRV software complex, followed by the analysis of the cardiorhythmogram according to the generally accepted method.

Results. The analysis of the obtained evidence showed that the total HRV (by all indicators was significantly reduced in patients with hypertonic disease compared with healthy individuals), and with the development of hypertensive crisis in patients with hypertonic disease was even lower. In the hypertonic disease group with hypertensive crisis, activation of the sympathetic division of the autonomic nervous system (with increasing LF/HF ratio) was detected, but despite a higher LF/HF index of 2,21 (0,86–3,94) there was no significant difference against level 1,85 (1,56–2,03) in the hypertonic disease group without hypertensive crisis and a value of 1,81 (1,66–1,89) among healthy persons (p > 0,05).

Conclusions. The results obtained indicate that the decrease in compensatory capacity in all HRV indicators is more pronounced in patients with hypertonic disease in the development of hypertensive crisis. Assessment of heart rate variability indicators may be a useful component of cardiovascular risk stratification, requiring further statistical analysis.

Investigation of adiponectin levels andintracardiac haemodynamic statehas been done in 96 patients divided into two groups (1st group – 64 hypertensive (stage II) overweight patients, medium age 59,0 (48,0–63,0) years; 2-nd group – 32 hypertensive (stage II) patients, medium age 58,0 (53,0–63,0) years, normal weight). Dependences between the left auricle size, blood pressure, and BMI increase, as well as between the left ventricle remodelling character and BMI in the surveyed patients were uncovered. Theconcentric left ventricle hypertrophy observed in the surveyed patients was characterised by normal contractility, leftventricle posteriorwall relative thickness increase, and normal or reduced end-diastolic volume. The blood serum adiponectin level in hypertensive (stage ІІ) overweight patients was significantly (nearly 3 times) lower as compared to the group of hypertensive (stage ІІ) patients who had normal weight.
AIR FREIGHT TRANSPORT IN POLAND
Authors: Wąsowska Katarzyna , Žukovskis Jan
Published: April 2020

Air transport is currently one of the major branches of transport both in the national – and global – economies. It is one of the fastest, most expensive, but at the same time also most effective types of transportation. It plays a fundamental role in the global economy, particularly in the transcontinental carriage of goods and passengers. Its availability and quality constitute a powerful driving force for a country’s development. Air freight transport, both in Poland and worldwide, is seen mostly from the angle of long-distance passenger flights. Given that, one often tends to forget the role of this transport branch in the case of freight transport. Air cargo transport is a booming branch with great development potential. The development of air freight is the key for gaining a competitive advantage by Polish enterprises. This, however, is related to considerable experience and knowledge on the part of both the carrier and the owner of goods with regards to the technical capacities of a given aircraft, maintenance costs, and rule awareness. The objective of the paper is to present the volumes of air cargo shipments in Poland and to identify the hazards and obstacles to its development. The study authors endeavour to analyse air freight transport in Poland. To this end, details will be presented regarding air cargo transport at Polish airports based on the Civil Aviation Authority (ULC) and Central Statistical Office (GUS) data and air market reports.
Operations in subterranean systems: Terrain and weather variable
Authors: Bartolomeu José
Published: April 2020

The overall objective of the research is to summarize tactical considerations, resulting from terrain and weather analysis, to support the preparation, planning and execution of subterranean operations. The study used the Grounded Theory for collection, analysis, and systematic treatment of data. The main data sources for the study consisted of purposive sampling from operations in subterranean systems and lessons learned from them. Two new sub-variables are now proposed to be included in terrain and weather variable from mission analysis model for subterranean operations: Subterranean system’s location and accesses and subterranean system features. The key to finding subterranean systems is through terrain analysis, physical ground search, operational indicators, and intelligence products. The analysis of the features of the subterranean system and its mapping is critical for developing courses of action. Forces must be trained and equipped to manoeuvre and combat at short distances and poor visibility conditions. Surface access points and command and control bunkers usually are assessed as key terrain. Obstacles placed at intersections are excellent ambush sites. Accessing sophisticated structures requires specific techniques and equipment. Inside the subterranean systems, existing angles, barriers, walls, cavities, stairwells and other objects provide cover and concealment. Water can make it impossible to build subterranean systems, place obstacles, or even use them; droughts can “create” new avenues of approach. Clouds and fog difficult the detection of subterranean systems. The terrain and weather analysis model, the characteristics, and the tactical considerations presented, all combined, support the preparation, planning, and execution of operations in subterranean systems.

Análisis de la cobertura del homicidio, desde el enfoque de producción noticiosa, en el diario “Al día”
Authors: Molina Jácome Isaías
Published: April 2020

Este artículo analiza la cobertura de las noticias sobre homicidios, en la etapa de su producción, enfocándose en los elementos con los que el diario sensacionalista ‘Al Día’ (Barranquilla-Colombia) da relevancia a las noticias y en los valores usados por los reporteros para elaborar la noticia. Para el análisis se utilizaron los estudios de la Sociología de la Producción Noticiosa o Newsmaking, como base teórica, con una metodología de corte cuali-cuantitativo, que cruzó un análisis de contenidos de 240 noticias de homicidio sucedidos durante cerca de cinco años (2008 a mayo 2012), y 6 entrevistas en profundidad realizadas con el equipo de periodistas. Se halló que el tema más importante en la cobertura de noticias es el hecho de sangre más  reciente, que el periodista usa una combinación de fuentes que incluye: familiares, testigos, autoridades y vecinos. Se identifican tres valores noticiosos: interés, cercanía y repercusión en la sociedad. Se concluye que las autoridades no tienen el monopolio de la información en el caso de los homicidios y que los valores  noticiosos tradicionales se aplican también a este medio sensacionalista, pero que, existen otros como: impacto, cercanía y repercusión.
Effects of surface treatment on Fermi level pinning at metal/GaN interfaces formed on homoepitaxial GaN layers
Authors: Isobe Kazuki , Akazawa Masamichi
Published: April 2020

The effect of chemical surface treatment on the uncontrolled surface oxide at a GaN surface and on Fermi level pinning at subsequently formed metal/GaN interfaces was investigated for a GaN epitaxial layer grown on a GaN substrate. The impact of several chemical treatments, including photolithography, on the surface oxide and the resultant surface band bending at the GaN surface was examined by X-ray photoelectron spectroscopy. Surface band bending was reduced by the reduction in the amount of uncontrolled surface oxide. The metal/GaN interfaces formed subsequent to these chemical treatments were investigated by electrical measurement for Schottky barrier diodes. We found that the reduction in the amount of uncontrolled surface oxide leads to an increase in the slope factor in the metal-work-function dependence of the Schottky barrier height. The mechanism of Fermi level pinning at the metal/GaN interface is discussed.

Published: April 2020

O presente artigo tem como objetivo analisar a construção de sexualidades de crianças que construíram as suas infâncias no entorno das prisões enquanto os pais, principalmente as mães, cumpriram pena de reclusão em unidades do sistema prisional. Com relação à sexualidade, a mesma é vivida pela pessoa individualmente, porém é constituída a partir do campo das relações sociais, da cultura, dos valores e formas sociais de vida. A base teórica do tema proposto centra-se na abordagem culturalista e social. Metodologicamente se define como uma pesquisa qualitativa, do tipo Estudo de Caso Etnográfico que permitiu o conhecimento dos significados e experiências culturais da infância através de uma descrição que apontou o sentido que as crianças dão a vida carcerária, como interpretam e estruturam, a partir desse sentido, o seu mundo. Foi constatado que crianças no presídio vivenciam as conseqüências das barreiras colocadas pela instituição, pois que no processo de identificação e reconhecimento, condição necessária da estruturação subjetiva, há uma convivência com modelos que experimentam a subordinação, violação e exclusão social. Diferentes parâmetros e padrões do comportamento sexual das pessoas reclusas são vivenciados por algumas crianças nas visitas e ingresso as unidades prisionais, sem que existam vigilância, orientação sexual e informações significativas para o desenvolvimento sexual de meninos e meninas.

Published: April 2020

Com base no aumento de diversos problemas sociais, principalmente aqueles relacionados à gravidez e a doenças sexualmente transmissíveis entre adolescentes, apresenta-se como proposta a necessidade de implantação da educação sexual nas escolas como forma de minimizar tais questões. A introdução da temática sobre sexualidade é um dos caminhos utilizados pelas instituições de nível superior para a efetiva qualificação de alguns seguimentos profissionais, principalmente aqueles que envolvam a formação do professor no curso de graduação em Pedagogia. Este artigo tem como objetivo analisar um planejamento educacional formal – um Plano de Curso. Esta análise tem como base o estudo de diversas correntes educativas que foram submetidas às alterações de acordo com o devir histórico-social; bem como a orientação do Ministério da Educação por meio dos Parâmetros Curriculares Nacionais(1988). Assim, ressalta-se a importância da inclusão de uma disciplina específica que envolva os temas sexualidade e orientação sexual nos diversos níveis da educação brasileira, mais especificamente nos cursos de formação de professores nível superior, como tendência atual de uma educação democrática, libertadora e transformadora com anuência do Estado, a fim de estimular a reflexão e a possível mudança de comportamento de crianças e de jovens a partir da problematização e do debate das diversas temáticas atuais sobre sexualidade, diversidade e cidadania, inspirado na própria realidade e experiência vivida pelos aprendizes.

Finding COVID-19 from Chest X-rays using Deep Learning on a Small Dataset
Authors: Hall Lawrence , Goldgof Dmitry , Paul Rahul , Goldgof Gregory M.
Published: April 2020

esting for COVID-19 has been unable to keep up with the demand. Further, the false negative rate is projected to be as high as 30\ and test results can take some time to obtain. X-ray machines are widely available and provide images for diagnosis quickly. This paper explores how useful chest X-ray images can be in diagnosing COVID-19 disease. We have obtained 135 chest X-rays of COVID-19 and 320 chest X-rays of viral and bacterial pneumonia.

 A pre-trained deep convolutional neural network, Resnet50 was tuned on 102 COVID-19 cases and 102 other pneumonia cases in a 10-fold cross validation. The results were

 an overall accuracy of 90.7% with a COVID-19 true positive rate of 0.83 and an AUC of 0.987,

 Pre-trained Resnet50 and VGG16 plus our own small CNN were tuned or trained on a balanced set of COVID-19 and pneumonia chest X-rays. An ensemble of the three types of CNN classifiers was applied to a test set of 33 unseen COVID-19 and 208 pneumonia cases. The overall accuracy was 94.4% with the true positive rate for COVID-19 of 0.969 with 6% false positives for a true negative rate of 0.94 and AUC of 0.99.

 This preliminary study has flaws, most critically a lack of information about where in the disease process the COVID-19 cases were and the small data set size. More COVID-19 case images at good resolution will enable a better answer to the question of how useful chest X-rays can be for diagnosing COVID-19.

 Note an earlier version of this work inadvertently used chest X-rays of viral and bacterial pneumonia that came from a dataset of children under 5 years old and those results should be ignored.

Цель исследования – мониторинг тяжелых металлов в растениях видов рода бузина. Задача исследования – выявление концентраций тяжелых металлов в плодах и листьях видов бузины. Наличие и концентрация тяжелых металлов варьирует в зависимости от видов бузины и частей растений. Повышенное содержание магния – у красноплодных видов (бузина красная Плюмоза Аурея, бузина сибирская, бузина, бузина красная Плюмоза, бузина корейская), причем его концентрация в плодах выше, чем в листьях – бузина сибирская (в 2 и 1,5 раза), при этом черноплодные виды (бузина черная, бузина канадская, бузина канадская ф. рассеченнолистная) имеют меньшую концентрацию магния. Концентрация меди в плодах и листьях превышает норму. В плодах в 7 (бузина красная Плюмоза Аурея) – 10 раз (бузина канадская ф. рассеченнолистная), в листьях в 2,5 (бузина корейская) – 6 раз (Бузина красная Плюмоза). Более интенсивно накапливают медь и алюминий черноплодные виды. Наибольшие концентрации вышеуказанных металлов в плодах, меньшие – в листьях. Наибольшее отклонение от нормы данного элемента отмечено в плодах и листьях бузины красной Плюмоза – в 12 и 8 раз, а наименьшее – бузины канадской – в 8 и 3 раза. Максимальное превышение нормы свинца в плодах выявлено у бузины корейской и бузины красной – в 2 раза, а в листьях – у бузины канадской ф. рассеченнолистная (2/3 от нормы). Превышение концентрации цинка в плодах и листьях бузины сибирской в 2 и 1,25 раза соотвтственно. Концентрация кобальта, никеля и стронция не имеет отклонений от нормы и колеблется от 1 до 46 % в плодах и от 1 до 49 % в листьях.

Цель исследования – применение категорий обогащения как отдельно, так и в сочетании, для увеличения двигательной активности и возможности реализации естественного поведения медведей. Материал собирался в г. Красноярске в Парке «Роев ручей». Использовались следующие категории обогащения: кормовое, предметное, визуальное, звуковое, запаховое, социальное, когнитивное, тренинг. За медведями велись фоновые наблюдения и круглосуточное видеонаблюдение. Заполнялись журналы наблюдений, проводился первичный анализ заинтересованности зверей на проведенные действия. В качестве предметного обогащения парка использовались пластмассовые бочки, игрушки (шары, конусы), шины и стволы деревьев, свежие ветки хвойных деревьев. Игрушки использовались медведями по настроению, их заинтересованность зависела от новизны предмета. Визуальное обогащение среды медведей выражалось в возможности наблюдать других медведей и осматривать окрестности парка с возвышенностей, расположенных в вольере. Для социального обогащения была сформирована пара белых медведей, во взаимоотношении друг с другом проявляющая социальное взаимодействие, которое происходит не только во время брачного сезона, но и круглый год. Реакция медведей на кормовое обогащение происходила всегда, у некоторых особей с задержкой во времени. С помощью тренингов возможно частичное либо полное избавление от приобретенных вредных привычек (стереотипии) и страхов (боязнь помещений перегонки, шума крупной техники, большого скопления народа). Чем чаще происходил тренинг с животным (частота зависит от настроения и желания животного), тем спокойней и активней они общались с посетителями. Интерес к запаховому обогащению проявлялся периодически. При обогащении среды для животных в зоопарках должны учитываться индивидуальные предпочтения каждой особи. Комбинированные методы обогащения среды, такие как запаховое + предметное, кормовое + предметное, кормовое + запаховое, вызывают больший интерес у животных, чем «чистые» методы.

Authors: Hajizade Elshan
Published: April 2020

In paper investigates issues dealing with some aspects of enhancing energy security and increasing energy efficiency. An extensive research related the role of energy in economic life and people’s business activity, as well as, its modern market system being formed as a global commodity was carried out. After analytic generalization, new interpretation of “Energy security” concept was presented. It was clarified once more that, in contemporary world, energy security is measured not only by the quantity of energy consumption supply, but also by its quality values and standards. Given the fact that in the Azerbaijan Republic, as in a sustainable social country, energy security is not separated from energy efficiency and is considered as an important indicator in the supply of fuel-energy resources for increasing the national development level of the economy, the paper intends to investigate these features. It also studies preparation of national energy security strategy and criteria, activities, and objectives that define its conditions being justified by analysis for
providing sustainability of these activities.
LANGUAGE – PROLIFIC SOURCE OF HUMAN MIND AND SPEECH
Authors: Karaia Tamar
Published: April 2020

ABSTRACT
The paper encloses different aspects of language and its facets which influences the social way of thinking and speaking in human behaviour. As we argue, generating new words and other fundamental changes in linguistic as the main part of language development, makes a profound impact on the components of culture and language simultaneously.
The article also reviews the strong power of human words and speech that makes unforgettable sense of human evolution. The central issue is how important the word expression is and so features of the words expressed by human beings actually reveal their attitude and the way they perceive the whole world. So, language has played a prominent role in human history. Furthermore, the things we use in our everyday lives rely on specialized knowledge or skills human race produce through the language. The information behind these was historically coded in verbal communications, and with the advent of writing it could be stored and become increasingly complex and sophisticated.
As it is underlined, the evolution of human spices absolutely depends on language, and if we carefully accept every change in as language with the correct approach to the issue, we really became inheritors of unusual and invaluable heritage.
MODERN METHODS TO DIFFERENTIATE BETWEEN CHEST PAIN AND CARDIAC ISCHEMIA
Authors: Javakhishvili Giorgi , Sujashvili Rusudan
Published: April 2020

Acute coronary syndrome (ACS) is a group of conditions which often present with similar signs and symptoms while having different outcomes and complications. Therefore it is essential to differentiate between them as soon as possible and provide appropriate management.
Acute coronary syndromes are classified into two categories: STE-ACS (ST segment Elevation Acute Coronary Syndrome) and NSTE-ACS (Non ST segment Elevation Acute Coronary Syndrome). STE-ACS stands for ST Elevation Acute Coronary Syndrome all of which demonstrate significant ST elevations on ECG due to complete blockage of artery by thrombus, while NSTE-ACS is due to partial occlusion of artery which exhibit ST segment depression and/or T wave inversions. Patients with NSTE-ACS who do not develop infarction are diagnosed with unstable angina, which itself is a precursor of myocardial infarction.
Acute coronary syndromes are considered multifactorial and risk factors most commonly associated with development of acute coronary syndromes include: hypertension, smoking, diabetes, obesity, sedentary life-style, hereditary conditions etc. Chronic stress to the coronary endothelium eventually leads to inflammation and atherosclerotic plaque formation. Plaque at some point with additional stress will rupture and trigger thrombus formation. Probability of plaque rupture depends on its composition: stable plaques contain small fatty core and thick fibrous cap, unstable plaque have larger fatty cores and thin fibrous cap.
Patients with acute coronary syndromes present with chest pain and/or discomfort and may experience tightness and pressure sensation; pain may radiate to left or both arms, jaw, back or stomach, sweating, dyspnea and dizziness are also common complaints.
Whenever we suspect ACS first diagnostic tests is always ECG (Electrocardiography). If ST segment is persistently elevated STEMI (ST Elevation Myocardial Infarction) can be diagnosed and reperfusion therapy is indicated; but if ST segment is depressed and/or T wave inversion is present laboratory tests are necessary for diagnosis. Cardiac biomarkers mainly used in the clinic are Troponins and CK-MB (Creatine Kinase MB), yet LDH (lactate dehydrogenase), B-type natriuretic peptide and C-reactive protein can be used additionally.
Several studies have been conducted in hopes to find other myocardial markers useful for diagnosis of ACS, one of which tested candidate biomarkers such as hFABP (Heart-type fatty acid binding protein), GPBB (Glycogen Phosphorylase Isoenzyme BB), S100, PAPP-A (Pregnancy-associated plasma protein A), TNF (Tumor Necrosis Factor), IL6 (Interleukin 6), IL18 (Interleukin 18), CD40 (Cluster of differentiation 40) ligand, MPO (Myeloperoxidase), MMP9 (Matrix metallopeptidase 9), cell-adhesion molecules, oxidized LDL (Low Density Lipoprotein), glutathione, homocysteine, fibrinogen, and D-dimer, procalcitonin. The idea of this study was to estimate usefulness of combining enzymatic markers with nonenzymatic ones in the clinical settings.
Societal Transformation and Regional Differentiation in Czechia: Developments in the Distribution of Job Opportunities and Population
Authors: Hampl Martin , Müller Jan
Published: April 2020

The paper focuses on consequences of societal transformation that result in changes in regional development tendencies, during the last two decades. It emphasizes early and more dynamic changes in the geographical distribution of economic activities as compared to population distribution. In spite of the time delay involved in population distribution dynamics, their transformation tends to lead to integration and the lower order processes of changes show a similar orientation. Divergent processes clearly dominated the last two decades. The article specifies basic differences in terms of the inequality of distributions of the assessed processes as well as degrees of changeability. First, there is an important difference between territorial and social differences, or inequalities. A secondary distinction is established between geographical scale levels, on the one hand, and the progress of functional subsystems (residential places – job locations – economic performance, etc.), on the other. Major factors conditioning regional differentiation are indicated. In particular, the attractiveness of a given geographical macrolocation and the educational level of its population appear to be critical conditions.
Urbanization and Suburbanization in the Urban Regions of Prague and Vienna: Structural Differences in the Presence of Different Political-Economic Regimes
Authors: Posová Darina , Sýkora Luděk
Published: April 2020

This article compares urbanization and suburbanization in the urban regions of Prague and Vienna, during the final decade of communism and the early years of transition to a capitalist society. In the 1980s, patterns of urbanization in the two cities differed radically with urbanization occurring in Prague and suburbanization developing in Vienna. The 1990s were characterised by rapid suburban growth rates in both cities. However, this growth was achieved in the presence of a specific structural characteristic, namely the low share of population and housing in the rings of the cities’ urban regions. In addition to suburbanization, Vienna continues to experience strong urban development of its city core through public support for new housing construction, housing rehabilitation, and the regeneration and conversion of old inner city brownfields. Sustainable development in Prague is currently threatened by a lack of development coordination at the urban regional level, which is leading to decentralization and an unregulated, fragmented, sprawl-like pattern of suburban growth.

Published: April 2020

Rett syndrome is a rare inherited neurodegenerative disease which mostly affects females but has a lethal impact on males. Rett syndrome is mostly caused by mutations of Methyl CpG binding protein-2 (MECP2) gene located on chromosome Xq28. A 7-year girl from a consanguineous Pakistani family presented with history of abnormal social behavior, tonic colonic seizures, limb'sataxia, intellectual disability, growth retardation and speech abnormalities. Physical and neurological examinations established likely clinical features of Rett syndrome with abnormal electroencephalogram (EEG). Genetic testing of MECP2 gene did not identify any functional nucleotide variation indicating the involvement of another gene mutation in this patient.A consanguineous case of Rett syndrome did not carry the mutation of MECP2 gene. Due to heterogeneity of the phenotype, it is proposed that there might be involvement of another locus for this disease. In future, targeted next generation sequence can be helpful to identify the causative mutation in this patient.
