Authors: Campos Roger Francisco Ferreira de , Tessaro Antonio Pedro 
Published: June 2019

As condições de trabalho em muitas empresas e indústrias possibilitam situações de risco à qualidade de vida dos seus colaboradores, dentre essas situações está à exposição aos altos níveis de ruído. Portanto, o presente trabalho tem como objetivo avaliar a higiene ocupacional de um colaborador no processo de extrusão de plástico em uma empresa de reciclagem, através da análise da emissão de ruído, com a perspectiva do cálculo de insalubridade. O trabalho foi realizado em uma empresa de recuperação de plástico do município de Caçador/SC, para os cálculos de insalubridade seguiu a partir da dose e exposição ao ruído conforme a NR-15 e NHO-01. Através do estudo pode-se observar que o colaborador da empresa está sob uma situação de exposição inaceitável, obtendo a consideração técnica como critica e nível de atuação recomendada para ações de controle urgente, conformes as diretrizes de cálculos da NR-15 e NHO-01, visto que o nível do ruído Leq é de 87,18 dB(A), buscando atenuar esse questão o colaborador recebe Equipamento de Proteção Individual (EPI) que atenua o ruído. Assim, é preciso de um monitoramento continuo da segurança do trabalhador em questão, visto que se o mesmo não realizar a utilização do EPI o mesmo pode sofrer consequências no seu processo de audição.

Fruit morphology, anatomy and relationships of the type species of Mastixicarpum and Eomastixia (Cornales) from the late Eocene of Hordle, southern England
Authors: Manchester Steven R. , Collinson Margaret E. 
Published: June 2019

Abstract
The Mastixiaceae (Cornales) were more widespread and diverse in the Cenozoic than they are today. The fossil record includes fruits of both extant genera, Mastixia and Diplopanax, as well as several extinct genera. Two of the fossil genera, Eomastixia and Mastixicarpum, are prominent in the palaeobotanical literature, but concepts of their delimitation have varied with different authors. These genera, both based on species described 93 years ago by Marjorie Chandler from the late Eocene (Priabonian) Totland Bay Member of the Headon Hill Formation at Hordle, England, are nomenclaturally fundamental, because they were the first of a series of fossil mastixioid genera published from the European Cenozoic. In order to better understand the type species of Eomastixia and Mastixicarpum, we studied type specimens and topotypic material using x-ray tomography and scanning electron microscopy to supplement traditional methods of analysis, to improve our understanding of the morphology and anatomy of these fossils. Following comparisons with other fossil and modern taxa, we retain Mastixicarpum crassum Chandler rather than transferring it to the similar extant genus Diplopanax, and we retain Eomastixia bilocularis Chandler [=Eomastixia rugosa (Zenker) Chandler] and corroborate earlier conclusions that this species represents an extinct genus that is more closely related to Mastixia than to Diplopanax.
Land use changes and landscape pattern dynamics of a peatland area under diversified human impact: the Grójec Valley (Central Poland)
Authors: Glina Bartłomiej , Sykuła Marcin , Mendyk Łukasz 
Published: June 2019

Abstract
The paper aims to assess the land use changes and the dynamics of the landscape pattern of the Grójec Valley in the scope of diverse anthropogenic impacts. The study site is located in the border of the Koło Basin and Kujawy Lakeland, Central Poland. This area was originally covered with wetlands. Since the beginning of the 20th century it has been influenced by intensive agricultural use, peat extraction and open-pit mining. The research is based on cartographic materials from 1941, 1981 and 2012. The most relevant finding was that in the first study period (1941–1981) the most common changes in land use (transformation of wetlands into grasslands with shrubs) took place. These were caused mainly by a change in hydrological conditions due to drainage for agricultural use (meadows and pastures) and peat extraction. The study confirmed that these land use changes significantly influenced the landscape structure in each of the analysed parameters (patch density and size, edge, shape and diversity metrics).
Subaqueous geomorphology: options, tasks, needs
Authors: Rudowski Stanisław , Wróblewski Radosław , Dworniczak Janusz , Szefler Kazimierz , Hac Benedykt , Gajewski Łukasz 
Published: June 2019

Abstract
The purpose of the paper is to present the potentialities of current non-invasive methods for bottom surveys, including cartometric presentation of its relief and structure in both marine and inland reservoirs. The paper presents examples of results obtained in the Maritime Institute in Gdańsk during surveys carried out at the bottom of seas, lakes and rivers with the use of the same apparatus: primarily, a multibeam echosounder (MBES) to obtain a digital terrain model (DTM); a side-scan sonar (SSS) to obtain a general image of the nature of the bottom (its “roughness”); and seismic profiling (sub-bottom profiler, sediment echo sounder [SES]) to recognise the structure of the bottom. The obtained results constitute a necessary basis for carrying out further specialist surveys (non-invasive or invasive) when needed. Current bottom survey options that use MBES, SSS and SES may be treated as subaqueous equivalents of the subaerial potentialities of a land surface survey using LiDaR and GPR (Ground Penetration Radar).
Quantum graphs and dimensional crossover: the honeycomb
Authors: Adami Riccardo , Dovetta Simone , Ruighi Alice 
Published: June 2019

Abstract
We summarize features and results on the problem of the existence of Ground States for the Nonlinear Schrödinger Equation on doubly-periodic metric graphs. We extend the results known for the two–dimensional square grid graph to the honeycomb, made of infinitely-many identical hexagons. Specifically, we show how the coexistence between one–dimensional and two–dimensional scales in the graph structure leads to the emergence of threshold phenomena known as dimensional crossover.
Genetic Algorithms vs. Knowledge-Based Control of PHB Production
Authors: Olteanu Marius , Paraschiv Nicolae , Koprinkova-Hristova Petia 
Published: June 2019

Abstract
The paper proposes an approach using Genetic Algorithm (GA) for development of optimal time profiles of key control variable of Poly-HydroxyButyrate (PHB) production process. Previous work on modeling and simulation of PHB process showed that it is a highly nonlinear process that needs special controllers based on human experience, as such fuzzy logic controller proved to be a good choice. Fuzzy controllers are not totally replaced, due to the specific process knowledge that they contain. The achieved results are compared with previously proposed knowledge-based approach to the same optimal control task.
Optimized Focused Web Crawler with Natural Language Processing Based Relevance Measure in Bioinformatics Web Sources
Authors: Mani Sekhar S. R. , Siddesh G. M. , Manvi Sunilkumar S. , Srinivasa K. G. 
Published: June 2019

Abstract
In the fast growing of digital technologies, crawlers and search engines face unpredictable challenges. Focused web-crawlers are essential for mining the boundless data available on the internet. Web-Crawlers face indeterminate latency problem due to differences in their response time. The proposed work attempts to optimize the designing and implementation of Focused Web-Crawlers using Master-Slave architecture for Bioinformatics web sources. Focused Crawlers ideally should crawl only relevant pages, but the relevance of the page can only be estimated after crawling the genomics pages. A solution for predicting the page relevance, which is based on Natural Language Processing, is proposed in the paper. The frequency of the keywords on the top ranked sentences of the page determines the relevance of the pages within genomics sources. The proposed solution uses a TextRank algorithm to rank the sentences, as well as ensuring the correct classification of Bioinformatics web page. Finally, the model is validated by being compared with a breadth first search web-crawler. The comparison shows significant reduction in run time for the same harvest rate.
Item Response Rates for Composite Variables
Authors: Eggleston Jonathan 
Published: June 2019

Abstract
Item response rates frequently serve as indicators of data quality and potential nonresponse bias. However, key variables from surveys, such as total household income or net worth, are often composite variables constructed from several underlying components. Because such composite variables do not have clearly identifiable response rates, inference on the data quality of these key measures is more difficult. This article proposes three new methods for aggregating data on response rates across questions to create a measure of item response for composite variables. To compare the three methods and illustrate how they can be used (both individually and collectively) to investigate data quality, I analyze item response for net worth in the Survey of Income and Program Participation (SIPP) and the Survey of Consumer Finances (SCF). These new measures provide detailed information about net worth estimates that would be difficult to assess without an item response aggregation method. Overall, these new item response rate methods provide a new way of describing data quality for key measures in surveys and for analyzing changes in data quality over time.
Determination of the Trajectory of Curvilinear Motion of Front Steering Wheels Driven Tractor
Authors: Dovzhyk M. , Tatyanchenko B. , Solarov A. , Sirenko J. , Roubík H. 
Published: June 2019

Abstract
The issue of designing the machine tractor movement trajectory is relevant today because its optimization significantly reduces fuel consumption and thus the transport costs. Proper choice of the energy machine and agricultural machinery with economy consumption of fuel and lubricants is also crucial. Recently, the problem has received scant attention in scientific literature. Therefore, this study analytically determines the trajectory of turning the tractor with front steering wheels and attempts to describe the curvilinear trajectory of a four-wheeled tractor using parametric equations in Cartesian coordinates. Its outcomes have a number of important implications for future practice; they are applicable e.g. in planning curved trajectories when cornering the tractor during field processing or in fuel and time consumption predictions for certain operations.

Summary
Cardiovascular diseases are the main cause of premature death worldwide. More than half of deaths were caused by cardiovascular diseases in 2017 in Lithuania. Primary prevention programmes encourage both medical staff and general population to pay attention to potential health issues as well as attempt to eradicate risk factors causing cardiovascular diseases. “A Funding Programme for the Screening and Preventive Management of the High Cardiovascular Risk Individuals” published in Lithuania has been implemented as of 2006.
Analysis of the results of the programme shows that the prevalent cases of arterial hypertension are gradually declining. However, the prevalence of dyslipidaemia is still not decreasing. The prevalence of other modifiable cardiovascular disease risk factors has erratic trends with a slight overall decline. Consequently, mortality rate of cardiovascular diseases has decreased by more than one third among middle-age population over the past 10 years.
Having higher availability of the anti-hypertensive and anti-lipid medications already achieved, the future plans include the aim of further reducing elevated blood pressure and effectively treating dyslipidaemia. In order to implement a strategy that focuses on smoking prevention, promotion of healthy nutrition and physical activity, a significant contribution is required from the state authorities.

Published: June 2019

Abstract
Wood constitutes the unique source of DNA in dead trees, but extraction of adequate quality DNA from dry wood is usually challenging. However, many different molecular studies require the use of such DNA. We have standardized and validated a modified CTAB protocol to isolate DNA from dry wood from Abies pinsapo and Cedrus atlantica species. Due to the degradation and very little DNA that is normally present in the wood from dead trees we have developed a PCR based test to certify the quality of the extracted samples. In the present study, we have proved too the effectiveness of this methodology to isolate DNA from conifer dry wood samples of sufficient quality to perform further molecular genetic experiments.

Published: June 2019

Summary
The ability to communicate in several foreign languages, recognize and understand cultural differences and effectively interact in a multicultural environment has become vital in the modern world that faces intense globalization processes. Linguistic and intercultural competences are essential not only for establishing personal relationships with foreigners but also for developing successful business relationships. At the Institute of Foreign Languages at Vytautas Magnus University (hereafter - VMU IFL), Spanish and German languages remain in the top five of the most popular languages among 30 languages available to students. These languages are chosen not only by Lithuanian students but also by foreign students who come to study in Lithuania. Most exchange students who come to study at VMU choose to study the Lithuanian language as well. In addition to the development of language skills in a learning process, the new concept of language teaching / learning, market trends and the great interest of students and the public in languages lead to the development of topics related to culture and intercultural communication and efforts to reveal peculiarities of the new culture in the common European and native country context. Based on the theories of different authors on the connection between culture and language and intercultural differences, the article discusses the possibilities of using commercials (video recordings of advertisements) to get acquainted with the culture in foreign language lectures. A comparative analysis of examples selected from commercials available online and revealing certain cultural aspects of the three countries (Spain, Lithuania and Germany) that allow to understand the target culture better is presented in this article. The aim is to reveal how a teacher, knowing the theories of cultural differences, can use commercials for the development of students’ linguistic and also cultural and intercultural competences.
