Seasonal Occurrence of Ibuprofen in Sediment, Water, and Biota in River Owena and Ogbese, and its Ecological Risk Assessment
Authors: Germaine A. Ogunwole , Joseph K. Saliu
Published: April 2020

The volume of pharmaceuticals discharged into the environment increases daily as a consequence of human life. In the present study, the seasonal variation of ibuprofen in sediment, biota, water, and their exposure risk were investigated in River Owena and Ogbese, Nigeria. The high-performance liquid chromatography coupled to a mass spectrometer (HPLC-MS/MS) was used to analyze the samples after clean up and pre-concentration by solid-phase extraction. The mean concentration of IBU in the samples spanned a range of 1.75 - 2.75 μg/g in sediment, 0.01 – 15.00 μg/g in fish, and 0.00002 – 0.005 μg/ml in water. The measurement of IBU in the sediment and water was significantly elevated in the dry season than the wet season, whereas the opposite was the case in biota. There was a significant interaction between season, media, and rivers with respect to IBU occurrence in the sampled rivers. The calculated bio-water accumulation factor (BWAF) was as high as 750,000 μg/g in fish, proving IBU is extremely bio-accumulative. The ecotoxicological risk assessment for average and worst possible outcome showed that the risk quotient (RQ) for IBU present in the water was sufficient to cause toxicity to fish in both freshwater bodies. The potential bioavailability of IBU to aquatic fauna for prolonged periods spanning several months can result in its circling back into the food web afterward. The baseline info provided by this study in these freshwaters may provide valuable information for the implementation of safety limits for the management of IBU influx into the environment.

Published: April 2020

A comparative study of pre- and post-flood households’ food security statuses in South-Eastern Nigeria was performed to answer the question “Do floods affect food security?” Data were generated via a survey of 400 households in eight communities using stratified and random sampling methods. Households’ food security statuses were assessed using the Household Food Security Survey Module (HFSSM) and computed using a Rasch analysis, where households were divided into four categories, namely: food secure, food insecure without hunger, moderately food insecure with hunger and severely food insecure with hunger. The results show that flooding affects food security negatively by increasing the number of food insecure households to 92.8%, and the regression coefficient of −0.798 indicates a very strong negative effect of flooding on household food security. An odds ratio of 2.221 implies that households that have experienced flooding are 2.221 times more probable to be food insecure than households that have not. The implication of the findings is that flooding is capable of turning communities into food insecurity hotspots that would need long-term assistance to cope, and flooding is capable of hampering the achievement of Goal 2 of the SDGs.
Dataveillance in the Workplace: Managing the Impact of Innovation
Authors: McParland Cliona , Connolly Regina
Published: April 2020

Background: Monitoring and surveillance are a fundamental part of the workplace environment, with employee performance and productivity as the main objects of scrutiny. However, many questions surround the ethical nature of managements’ ability to employ advanced digital technologies to monitor employee behaviour and performance while in the workplace. If unaddressed, these concerns have the potential to significantly impact the relationship between the employee and the employer, impacting trust in management resulting in negative attitudes and counterproductive behaviours.

Objectives: The goal of this paper is to present a comprehensive review of workplace surveillance whilst outlining some of the emerging issues relating to the use of employee monitoring technologies in the workplace.

Methods/Approach: A detailed review of the literature was conducted in order to identify the major issues relating to workplace surveillance. In addition, a number of practitioner-based studies were examined to extract and identify emerging trends and concerns at an industry level.

Results: Workplace surveillance is on the rise; however, empirical studies are in short supply.

Conclusions: The issue of workplace surveillance is an under-researched area, which requires much attention. There is a distinct need for clear measures and structures that govern the effective and fair use of communication technologies in the workplace.
What are the Limiting Factors During an Ultra‐Marathon? A Systematic Review of the Scientific Literature
Authors: Garbisu-Hualde Arkaitz , Santos-Concejero Jordan
Published: April 2020

This review aimed to analyse factors that limited performance in ultra-marathons and mountain ultra-marathons. A literature search in one database (PubMed) was conducted in February 2019. Quality of information of the articles was evaluated using the Oxford´s level of evidence and the Physiotherapy Evidence Database (PEDro) scale. The search strategy yielded 111 total citations from which 23 met the inclusion criteria. Twenty one of the 23 included studies had a level of evidence 2b (individual cohort study), while the 2 remaining studies had a level of evidence of 5 (expert opinion). Also, the mean score in the PEDro scale was 3.65 ± 1.61, with values ranging from 0 to 7. Participants were characterised as experienced or well-trained athletes in all of the studies. The total number of participants was 1002 (893 men, 86 women and 23 unknown). The findings of this review suggest that fatigue in ultra-endurance events is a multifactorial phenomenon that includes physiological, neuromuscular, biomechanical and cognitive factors. Improved exercise performance during ultra-endurance events seems to be related to higher VO2max values and maximal aerobic speed (especially during submaximal efforts sustained over a long time), lower oxygen cost of transport and greater running experience.

Authors: Rago Vincenzo , Brito João , Figueiredo Pedro , Krustrup Peter , Rebelo António
Published: April 2020

This study aimed to examine the interchangeability of two external training load (ETL) monitoring methods: arbitrary vs. individualized speed zones. Thirteen male outfield players from a professional soccer team were monitored during training sessions using 10-Hz GPS units over an 8-week competitive period (n = 302 observations). Low-speed activities (LSA), moderate-speed running (MSR), high-speed running (HSR) and sprinting were defined using arbitrary speed zones as <14.4, 14.4–19.8, 19.8–25.1 and ≥25.2 km·h-1, and using individualized speed zones based on a combination of maximal aerobic speed (MAS, derived from the Yo-yo Intermittent recovery test level 1), maximal sprinting speed (MSS, derived from the maximal speed reached during training) and anaerobic speed reserve (ASR) as <80% MAS, 80–100% MAS, 100% MAS or 29% ASR and ≥30% ASR. Distance covered in both arbitrary and individualized methods was almost certainly correlated in all speed zones (p < 0.01; r = 0.67-0.78). However, significant differences between methods were observed in all speed zones (p < 0.01). LSA was almost certainly higher when using the arbitrary method than when using the individualized method (p < 0.01; ES = 5.47 [5.18; 5.76], respectively). Conversely, MSR, HSR and sprinting speed were higher in the individualized method than in the arbitrary method (p < 0.01; ES = 5.10 [4.82; 5.37], 0.86 [0.72; 1.00] and 1.22 [1.08; 1.37], respectively). Arbitrary and individualized methods for ETL quantification based on speed zones showed similar sensitivity in depicting player locomotor demands. However, since these methods significantly differ at absolute level (based on measurement bias), arbitrary and individualized speed zones should not be used interchangeably.

Personality traits, especially in sport are modulatory factors of athletes’ behavior – his/ her conscientiousness, the will to achieve an aim, perseverance and motivation of activity. Not only are biological predispositions related to anatomical or biochemical traits of success, but they are also largely determined by personality traits that result from genetic factors. In our research we joined tests of athlete’s personality in correlation with genotypes of the dopamine transporter (DAT1) gene polymorphism. The selection of this polymorphism was based on previous reports connecting the influence of dopamine with motivation and numerous arguments supporting its correlation with human behavior. We observed significant differences among polymorphisms DAT 9/9, 9/10, 10/10 in terms of proportion of particular genotypes between athletes and the control group. We also found significant differences in the NEO FFI sten scale for conscientiousness. We noticed that anxiety was related with genotypic variants of DAT1, specifically the 9/10 VNTR variant, which conditioned lower levels of anxiety in the group of tested athletes. By contrast, the lower sten value of agreeability was statistically significant for the group of athletes that were carriers of the 10/10 VNTR genotype. Heterozygous 9/10 VNTR among athletes showed lower levels of anxiety in comparison with the control group, whereas agreeability determined using the NEO FFI scale represented a lower value among athletes that had the 10/10 polymorphism. We may thus conclude that the presence of polymorphic variants of the dopamine transporter gene corresponds to athletes’ personality traits.
Ageing Entrepreneurs and Business Transfer Challenges in Croatia
Authors: Juric Petra Mezulić , Alpeza Mirela , Peterka Sunčica Oberman
Published: April 2020

Business transfer as a research topic awakened the interest of researchers in the past few decades. Business transfer is defined as a change of ownership of any firm to another person or legal entity assuring the continuous existence and commercial activity of the enterprise, and it encompasses different kinds of transfers both to family and non-family members. Ageing and consequently retirement are often mentioned as the reasons for entrepreneurs’ exits from the companies and intention to initiate the business transfer process. A successful business transfer process is one of the key prerequisites for long-term sustainability of small and medium-sized enterprises. There is a significant number of ageing business owners in Croatia who will exit their companies in the coming years. Considering the number of these entrepreneurs and the influence their exits can have on company stakeholders and national economy in general, it is of great importance to better understand the factors that can influence the choice of their exit strategies. The aim of the paper is to provide an understanding of the dilemmas that the ageing entrepreneurs face when considering different exit modes. The data for the study was collected through in-depth, semi-structured interviews conducted with six ageing business owners. The analysis of the interviews enabled the identification of the challenges that ageing entrepreneurs face in the business transfer process: emotional attachment to the firm, strong preference for family succession and concerns about financial security after retirement. Some of these challenges are a result of the undeveloped business transfer ecosystem, strong tradition and cultural values that imply family succession as the only acceptable exit strategy for retiring company owners in Croatia.

Published: April 2020

The paper is intended to provide information on the trade war between China and the USA. It analyses the consequences of the trade dispute, discusses the impact on an Austrian company in the steel sector, gives an overview of possible strategies with which companies can reduce the negative effects of tariffs and discusses strategies that are good options for companies in the steel industry. The methodology applied included theoretical and empirical research based on quantitative analysis as well as quantitative research in the form of expert interviews. The results show that the trade war between China and the USA was in full swing until January 2020. The impacts do not only affect the parties involved, but also other parties such as the EU. Companies can use a variety of strategies to mitigate the negative effects of trade wars. The best strategy for a company depends on the structure of the company, its products and its competitors. The paper adds new insights to the existing literature on the trade war between China and the US and its effects, strategies to mitigate the negative effects of tariffs and discussions on optimal strategies for companies in the steel industry.
Traditional Procurement versus Public-Pivate Partnership: A Comparison and Synergies with Focus on Cross-border Contracts
Authors: Štěrbová Ludmila , Halík Jaroslav , Neumannová Pavla
Published: April 2020

Government purchases represent an important part of the world economy. Selling to the public sector is a key business activity for certain industries or service providers. The public procurement segment’s attractiveness is also underlined by the security of payment and large extent of supplies. With globalisation as a worldwide phenomenon, businesses do not have to rely only on domestic institutions; they can enter international B2G markets as well. However, the ability of private companies to do business with foreign governments is limited by various national legislations as governments settle the procurement regulation with respect to their national interests. In the following overview article, the authors analyse the two main and typical procurement types – traditional procurement and public-private partnership – with regard to recent development trends, international regulatory framework, opportunities and barriers to entry for European businesses. The main goal of the paper is to define, based on this analysis, the main differences and possible synergies of the traditional procurement and public-private partnership while focusing on cross-border contracts. This paper can be regarded as useful for business, academia as well as the public sector.

Authors: Molchanova E.V.
Published: April 2020

Subject. This study focuses on the Finno-Ugric peoples carrying unique cultural customs and traditions.
Objectives. I evaluate how various factors influence the demographic development of the Finno-Ugric peoples.
Methods. Analyzing the current situation, I refer to official statistics and the Health for All database of the World Health Organization, statistical yearbooks of the Russian State Statistics Service. All data were organized as a special information system including several related blocks, such as economic development of locations, demographic situation, health and healthcare. Research was based on the comparative analysis of key medical-demographic and socio-economic indicators, and economic-mathematical apparatus.
Results. I comprehensively evaluated the current situation macro- and mesoeconomically by gradually shifting from the comparison of countries to regional trends. I traced patterns of medical and demographic processes in the Finno-Ugric countries, such as Hungary, Finland and Estonia, and national autonomies across Russia.
Conclusions and Relevance. I discovered that there is a certain relationship between a man and environment that translate into physical and physical health of people. They should be taken into consideration when outlining demographic development programs. The findings can be used to prepare regional medical and demographic documents, including the prevention of suicidal behavior and alcoholism and general medical services.

Authors: Balintag Christopher Molingit , Wilang Jeffrey Dawala
Published: April 2020

Background:Numerous positive gains have been reported on the use of technology in language learning. The current survey of published journal articles reveals a lack of research on its integration to language teaching and learning in graduate language classrooms in EFL settings. In this study, the use of QR codes in the graduate EFL classroom has been investigated concerning its relatedness to affective language learning attributes (herein referred to as ALLAs) including anxiety, engagement, motivation, self-esteem, among others during the lesson on the process of writing. Three objectives were sought (1) to know studentsâ€™ perceptions on ALLAs before and after the use of QR codes, (2) to establish the relationship between studentsâ€™ perceived ALLAs and language performance, and (3) to understand specific situations that trigger positive or negative reactions.Methodology:The students were asked to indicate their perceptions concerning ALLAs by using a survey questionnaire before and after the activity. They were also asked to do the QR codes activity to create an essay outline. Further, an open-ended questionnaire was provided to indicate their negative or positive reactions to specific situations during the QR-coded activity.Findings:Results suggest the following (1) there are significant differences in the studentsâ€™ perceived ALLAs before and after the activity, (2), there is a significant positive correlation between ALLAs and language performance, and (3) twelve specific situations were found to provoke dynamic ALLAs reactions.Conclusion:It is suggested that the use of available technological innovations must be introduced to graduate language teachers as its impacts on ALLAs are overwhelmingly beneficial.

Entre la guerra y la cocina: La metáfora en el discurso periodístico español desde la perspectiva de la lingüística cognitiva
Authors: Al.Amar Abdullah M.
Published: April 2020

The main objective of this paper is to analyze the political metaphor in in Spanish journalistic discourse from the perspective of cognitive linguistics. For this purpose, a selection of journalistic citations was selected on the occasion of the political events that took place in Spain, from 1977 to 1988. The theoretical foundations of the analysis are developed within the framework of the cognitive linguistic focus, with special emphasis on the work of G. Lakoff Metaphor and war (1991) and Hernández in his work The Political Metaphor in the Venezuelan Press (2004). Regarding the argumentative functions of metaphor, we have chosen the cognitive function mode analysis in different journalistic contexts. However, to reach our purpose of analysis, we have chosen the field of war and cooking as the metaphorical fields most used by the current Spanish press. It is concluded that the analysis of the metaphorical processes in the journalistic discourse allows us to observe the way in which the issuers perceive and conceptualize the political events that are collected by the journalists.
Autoinflammatory syndromes: A review

Published: April 2020

Autoinflammatory syndromes (AIS) are disorders of innate immunity which present with recurrent episodes of fever and skin lesions, such as urticaria, pustules, maculopapular rash, oral ulcers, generalized pustular psoriasis, or pyoderma gangrenosum-like lesions. The different entities that come under AIS are familial Mediterranean fever, tumor necrosis factor receptor-associated periodic syndrome, hyperimmunoglobulinemia D with periodic fever syndrome, and cryopyrin-associated periodic syndromes. Many new entities are also described. As many of them present with skin lesions, dermatologists should be aware of myriad of clinical features associated with these disorders. Childhood onset, positive family history, and elevated laboratory markers of systemic inflammation during acute episodes are the clues to diagnosis. Infections, connective tissue diseases, and malignancies should be excluded before diagnosing AIS.

Published: April 2020

Impact of research is generally measured through citation counts. For author impact, the most common impact indices considered are the h-index, i10-index, and the g-index, of which the h-index is the most commonly used. There are various resources available for retrieving researcher h-indices. The most common databases used for the same are Scopus, Google Scholar, and “Web of Science.” Ethical issues related to the use of these resources for h-index calculation include – gaming/manipulation and fake citations. An issue which we have noticed cropping up of late, is researchers claiming erroneous h-indices.

Voltage Relaxation to Detect the Onset of Lithium Plating on Graphite for Fast Charging
Authors: Konz Zachary M. , McShane Eric J. , McCloskey Bryan D.
Published: April 2020

Li-ion battery fast charging is critical to reduce electric vehicle ‘range anxiety’ and enable emerging technologies such as aerial drones and high-performance portable electronics. Fast charging is primarily limited by lithium plating on graphite, which can cause capacity fade and catastrophic cell shorting. The ability to detect the initial onset of lithium plating using easily accessible battery management system parameters (current, voltage, and capacity) would dramatically improve the safety of fast charging protocols. In this work, we highlight the application of a differential open-circuit voltage analysis (dOCV) to detect when Li plating first begins during room temperature fast charging. We quantify the Li detection limit of the technique to be approximately 4 mAh plated Li per gram graphite, showing that this method has high sensitivity and significant commercial promise.
Viribus Unitis: Drug Combinations as a Treatment Against COVID-19
Authors: Muratov Eugene , Zakharov Alexey
Published: April 2020

The opportunities that may be provided by synergistic antiviral action of drugs for battling SARS-CoV2 are currently underestimated. Modern AI technologies realized as text, data, and knowledge mining and analytics tools provide the researchers with unprecedented opportunities for “smart” design of drug combinations with synergistic antiviral activities. The goal of this study is to emphasize the combination therapy as a potential treatment against COVID-19 and to utilize the combination of modern machine learning and AI technologies with our expertise to select the most promising drug combinations with further experimental validation. To the best of our knowledge, we are the first who applied the combination of data, text, and knowledge mining and modeling towards identification of drug combinations against SARS-CoV2. As a result, we have identified 281 combinations of 38 drugs that may serve as potential treatment for COVID-19. Among them, we selected twenty binary combinations that were submitted to experimental testing and twenty treble drug combinations that will be submitted for experimental testing as soon as necessary infrastructure will be developed. We hope that this study will promote the combination therapy as an efficient treatment for COVID-19.

No one has even imagined that infection in the respiratory system in the form of pneumonia because of novel coronavirus (SARS-CoV2) in small town of China, Wuhan during end of December in the year 2019 will come out as an extremely communicable infection. The World Health Organization (WHO) has acknowledged the current epidemic as a threat to whole population worldwide. At present, still we have not reached the advanced levels of research to treat and control this contagious disease. Due to lack of information about the pathogenesis and proliferation pathways of this novel corona virus, whole world is looking forward for its exact prophylaxis. On the basis of recent proofs provided by review and research articles from various genuine sources, we tried thoroughly to summarize the various factors regarding COVID-19 like its epidemiology, clinical characteristics, diagnosis, treatment and prevention. Through this review we have made an effort to present a common conceptual literature on coronavirus to help community to fight against this dangerous virus, and will hope that this review will be a source of reference to young researchers for advanced studies.

As queimadas impactam negativamente a biodiversidade dos ecossistemas naturais, alterando os atributos físicos e biológicos e influenciando os fluxos de energia e biogeoquímicos. Sendo assim, o objetivo deste trabalho foi analisar através do sensoriamento remoto o efeito de áreas queimadas sobre os índices espectrais NDVI (Índice de Vegetação por Diferença Normalizada) e NBR (Índice de Queimada Normalizada) e na temperatura de superfície no Parque Estadual do Araguaia (PEA) em Mato Grosso, Brasil. Imagens do satélite de Landsat 8 OLI foram utilizadas para analisar a superfície no período pré-queimada (15/06/2015) e pós-queimada (21/10/2015) no Parque Estadual. Os resultados demonstraram que o NDVI apresentou maiores valores nas áreas com vegetação densa e menores valores em solo exposto, associados à vegetação seca, carbonização ou com completa ausência de vegetação. O NBR apresentou valores negativos nas áreas queimadas, devido ao aumento da refletância após passagem do fogo devido à deposição de cinzas brancas. A temperatura da superfície foi maior no pós-queimada relacionada a uma maior capacidade de absorção da superfície (cor preta das cinzas). Estes resultados são atribuídos aos efeitos combinados de maior exposição do solo, aumento da absorção da radiação pela vegetação carbonizada e redução da evapotranspiração relativa à vegetação verde existente no período pré-queimada.  Spectral Indexes and Surface Temperature on Burnt Areas at Araguaia State Park in Mato Grosso A B S T R A C TFires harm the biodiversity of natural ecosystems, changing physical and biological attributes and influencing energy and biogeochemical flows. Therefore, the objective of this work was to analyze through remote sensing the effect of burnt areas on the NDVI (Normalized Difference Vegetation Index) and NBR (Normalized Burn Index) spectral indexes and on the surface temperature in Araguaia State Park (PEA) in Mato Grosso, Brazil. Satellite images of Landsat 8 OLI were used to analyze the surface in the pre-burned (06/15/2015) and post-burned (10/21/2015) period in the State Park. The results showed that NDVI showed higher values in areas with dense vegetation and lower values in exposed soil, associated with dry vegetation, carbonization or with a complete absence of vegetation. The NBR showed negative values in the burnt areas, due to the increase in reflectance after the passage of the fire due to the deposition of white ash. The surface temperature was higher in the post-firing period due to a greater absorption capacity of the surface (black color of the ashes). These results are attributed to the combined effects of greater soil exposure, increased absorption of radiation by carbonized vegetation and reduced evapotranspiration relative to green vegetation in the pre-burned period.Keywords: Fire; Protected Area; Remote Sensing.

O aumento de temperatura do ar é uma realidade inquestionável. Vários trabalhos em macroescala confirmam esse fato, mas é preciso melhorar nossa compreensão, também, em escalas menores. O objetivo desse estudo foi analisar e comparar as normais climatológicas das temperaturas máxima, mínima e média compensada do período de 1961-1990 (normal de referência) com as normais climatológicas provisórias de 1994-2015, com o propósito de identificar mudanças nos padrões de temperatura e obter uma avaliação mais refinada das mudanças climáticas ocorridas nas últimas décadas no estado do Ceará, Brasil. Para tal, utilizou-se do banco de dados meteorológicos do INMET. O comportamento das temperaturas máxima, mínima e média compensada revelou para todas as estações selecionadas, um padrão de aumento do período 1994-2015 em relação ao período 1961-1990, da ordem de 0,7 oC, 0,4 oC e 0,6 oC em média, respectivamente. Destaca-se que esse aumento alcançou todo o estado mas, como cada localidade apresenta particularidades, a alta da temperatura não foi uniforme variando em função do setor do estado. As temperaturas médias foram “puxadas” para cima mais por conta dos aumentos das temperaturas máximas do que devido às medidas das temperaturas mínimas.Palavras-chave: Aquecimento do Ar; Normais Climatológicas; Mesoescala.  Space-Time Analysis of Temperatures in Ceará in the Context of Climate Change  A B S T R A C TSpatiotemporal analysis of temperatures in Ceará-Brazil in the context of climate change. The rise in air temperature is an unquestionable reality. Several studies in macroscale confirm this fact, but we must improve our understanding also at smaller scales. The aim of this study was to analyze and compare the climate normals of maximum, minimum and average temperature of the 1961-1990 period (normal reference) with the provisional climate normals from 1994 to 2015, with the purpose of identifying changes in temperature patterns and a more refined assessment of climate change over the past decades in the state of Ceará. For this, the database is used, taken from the National Meteorological Institute of Brazil (INMET). The behavior of the maximum, minimum and average temperature revealed for all selected stations, a pattern of increased period 1994-2015 for the period 1961-1990, in the order of 0.7 °C, 0.4 °C and 0.6 oC in average, respectively. It is noteworthy that this increase reached throughout the state but as each location has special features, the temperature rise has not been uniform. It changed due to the state section. Average temperatures were "pulled" up more because of the rise in maximum temperatures that due to the measures of minimum temperatures.Keywords: Air Warming, Climate Normals, Mesoscale.

A expansão agrícola no Município de Sorriso no Estado de Mato Grosso se deu nos anos 70 com o favorecimento do governo federal estimulando a chegada de famílias provenientes do Sul do País. Diante disso, o objetivo desse trabalho foi avaliar a dinâmica espaço-temporal do NDVI no Município por meio de sensoriamento remoto. Utilizou-se imagens do satélite Landsat-5 (TM), entre os anos de 1984 e 2011. O processamento dessas imagens foi realizado por meio do programa ArcGIS 10.3 e linguagem Python. A estimativa da expansão das áreas de cultivo e quantidade de áreas de mata nativa do Município foi calculado através do índice de vegetação da diferença normalizada - NDVI. Nossos resultados sugerem que as possíveis mudanças ocorridas no solo do Município podem estar afetando as variáveis climatológicas como a temperatura da região. O estudou demonstrou também que a expansão agrícola se intensificou após a emancipação do Município, com grande crescimento das áreas de cultivo e urbanização, tendo como consequência a diminuição das áreas de mata nativa.Palavra-chave: Processamento de imagens, Satélites, Índices de vegetação. Study of NDVI spatiotemporal dynamics in the city of Sorriso-MT A B S T R A C TThe Sorriso-MT city is considered the agribusiness capital in Brazil and the largest single soy producer in the world. The agricultural expansion of Sorriso in the state of Mato Grosso occurred in the 70's with the favor of the federal government encouraging the arrival of families from the south of the country. Therefore, the objective of this work was to evaluate the spatial-temporal dynamics of NDVI in the Municipality through remote sensing. Landsat-5 (TM) satellite images were used between 1984 and 2011. These images were processed using the ArcGIS 10.3 program and Python language. The estimate the expansion of the cultivated areas and the amount of native forest areas of the Municipality was calculated through the normalized difference vegetation index - NDVI. Our results suggest that possible changes in the soil of the municipality may be affecting climatic variables such as the region temperature. The study also showed that the agricultural expansion intensified after the emancipation of the Municipality, with great growth of cultivation and urbanization areas, resulting in the reduction of native forest areas.Keywords: Image processing, Satellites, Vegetation indexes

Изучена возможность выделения в твердую фазу нитратокомплексов платины(IV) из азотно-кислого раствора гидроксида платины(IV) в виде аддуктов с дибензо-18-краун-6, 15-краун-5 и 12-краун-4 эфирами. Обнаружено, что при испарении азотно-кислых растворов, содержащих 15-краун-5 эфир (15-С-5), образуется поликристаллический продукт — преимущественно смесь фаз состава (H3O⊂15-С-5)2[Pt(NO3)6] (1), (H3O⊂15-С-5)2(15-С-5)[Pt(NO3)6]∙2H2O (2) и (15-С-5)[Pt4(μ3-OH)2(μ2-OH)4(NO3)10]∙3H2O (3). Структура указанных соединений определена методом рентгеноструктурного анализа. В случае эфира дибензо-18-краун-6 взаимодействие с азотно-кислым раствором платины приводит к образованию плохо растворимого тетранитропроизводного макроциклического эфира. Испарение азотно-кислых растворов платины, содержащих эфир 12-краун-4, не позволяет получить твердые кристаллические фазы.
