Genetic Loci Governing Androgenic Capacity in Perennial Ryegrass (Lolium perenne L.)
Authors: Begheyn Rachel F , Yates Steven A , Sykes Timothy , Studer Bruno
Published: April 2018

Immature pollen can be induced to switch developmental pathways from gametogenesis to embryogenesis and subsequently regenerate into homozygous, diploid plants. Such androgenic production of doubled haploids is particularly useful for species where inbreeding is hampered by effective self-incompatibility systems. Therefore, increasing the generally low androgenic capacity of perennial ryegrass (Lolium perenne L.) germplasm would enable the efficient production of homozygous plant material, so that a more effective exploitation of heterosis through hybrid breeding schemes can be realized. Here, we present the results of a genome-wide association study in a heterozygous, multiparental population of perennial ryegrass (n = 391) segregating for androgenic capacity. Genotyping-by-sequencing was used to interrogate gene- dense genomic regions and revealed over 1,100 polymorphic sites. Between one and 10 quantitative trait loci (QTL) were identified for anther response, embryo and total plant production, green and albino plant production and regeneration. Most traits were under polygenic control, although a major QTL on linkage group 5 was associated with green plant regeneration. Distinct genetic factors seem to affect green and albino plant recovery. Two intriguing candidate genes, encoding chromatin binding domains of the developmental phase transition regulator, Polycomb Repressive Complex 2, were identified. Our results shed the first light on the molecular mechanisms behind perennial ryegrass microspore embryogenesis and enable marker-assisted introgression of androgenic capacity into recalcitrant germplasm of this forage crop of global significance.

Authors: Gasemi Sona , Poorhashemi Seyed Abbas , Zare Ali , Farshchi Parvin , Bavand Hermidas
Published: April 2018

According to the Convention on the Law of the Sea 1982, constructing artificial island is permitted and countries can construct artificial islands in their own territory. Constructing artificial islands in the Persian Gulf area makes the countries in the region, especially Iran, to pursue the issue with more sensitivity. According to data dissemination principle of International Environmental Law, the countries that construct artificial islands should notify other states regarding construction and properties of their own artificial islands. Today, artificial island construction is being increased and this has caused many environmental crises including increase of water darkness and pollution and transport of coastal sediments. In this study, the destructive results of constructing artificial islands in the Persian Gulf environment, the effect of development of new land space from geopolitical view, and also constructing artificial islands from the viewpoint of International Law of the seas are being reviewed. Moreover, according to the fact that the notion of governance in modern International Law have been modified regarding the use of environment and sustainable development, the states will have limited right to construct artificial islands.
Peculiarities of growth and lipoxygenase activity of wild fern Dryopteris filix-mas (L.) Schott
Authors: Babenko L. M. , Kosakivska I. V. , Voytenko L. V.
Published: April 2018

We studied the peculiarities of growth, localization and dynamics of lipoxygenase activity in sporophyte organs of wild fern Dryopteris filix-mas (L.) Schott at various stages: intensive growth; sori ripening; spore release; summer vegetation, and vegetation termination. Morphometric analysis showed that the weight of one plant during sporophyte ontogenesis varied from 130 to 150 g. Frond length varied from 11 to 85 cm. Diameter of the overground part of rhizome was 9-10 cm. In the stage of spore release and during the summer vegetation we mentioned 7 fronds on plant, and in the phase of vegetation termination – 18. The plants had the biggest weight in phase of spore release. Following spore release and at the beginning of vegetation termination, the frond weight diminished almost by two times. An intensive elongation of fronds was observed prior to the start of spore release. When fronds unfold and grow the number of segments of the first order increase from 39 to 47 pairs. Frond length in the stage of summer vegetation increased from 4.3 to 11.2 cm (9 pairs), and then it gradually decreased from 10.2 to 0.1 cm (39 pairs) that resulted in the formation of a lanceolate lamina. In the stage of vegetation termination, the fern had 18 fronds, 12 of which remained green, while the rest dried and turned greyish-brown. The frond lamina contained 47 pairs of segments of the first order whose length increased from 4.5 to 10.5 cm, and then it diminished from 9.5 to 0.05 cm. The rhizome weight was in the range of 110.2–115.7 g in all the stages except vegetation termination. The morphological analysis showed that plants had successfully passed all developmental phases, reached their normal dimensions, had a mass spore formation, no external signs of suppression and damages, and this was generally consistent with the highest level of life state assessment. Localization and dynamics of lipoxygenase (LOX) activity in organs of the sporophyte of D. filix-mas have been studied. We registered that fronds contained 13-LOX with рНopt. values of 7.2, rhizomes – 9-LOX (рНopt. 6.5). Peculiarities that were mentioned in localization and dynamics of LOX isoforms catalytic activity in the fern organs at various phases of development suggest that the enzyme might be involved in the regulation of lipid metabolism of growth processes that ensure plant adaptation to the environment.

Authors: Aminoroayaei Negar , Shahedi Bahram
Published: April 2018

In the current century, a suitable strategy is concerned for optimal consumption of energy, due to limited natural resources and fossil fuels for moving towards sustainable development and environmental protection. Given the rising cost of energy, environmental pollution and the end of fossil fuels, zero-energy buildings became a popular option in today's world. The purpose of this study is to investigate the factors affecting the design of zero-energy buildings, in order to reduce energy consumption and increase productivity, including plan form, climatic characteristics, materials, coverage etc. The present study collects the features of zero-energy building in Isfahan, which is based on the Emberger Climate View in the arid climate, by examining the books and related writings, field observations and using a descriptive method, in the form of qualitative studies. The results of the research showed that some actions are needed to save energy and, in general, less consumption of renewable energy by considering the climate and the use of natural conditions.

Published: April 2018

The article presents the materials of long-term studies of the ornithofauna of the floodplain of the middle reaches of the Zgar River within the limits of the zoological reserve of the national significance of "Zgarsky", located within the limits of the Litinsky and Zhmerinsky regions of the Vinnytsia oblaast. The study of the species structure, the nature of topical bonds, and the ecological groups of the avifauna, revealed the peculiarities of the dynamics of the population density of the bird sanctuary in the main types of biotopes during 2005-2017. The territory's avifauna structure comprises 169 species of birds, of which 86 species are nesting and migratory, 38 - settled, 31 – on passage, 12 - wintering, 2 – nomadic. The dominant species of bird communities were obligatory and optional zoophages (124 species), some fewer were phytophagous (38 species) and polyphagous (7 species). The trends in quantitative indices of the ornithofauna demonstrates the tendency to increase the role of dendrophiles species in the formation of nesting bird communities of all the habitats, including meadow and wetlands. We also registered that the ratio of camphoric species in meadow bird communities is decreased. This occurs due to the backdrop of reduced man-caused load and acceleration of natural successional processes, which are accompanied by overgrown shrub-tree phyto-associations of most habitats. The highest indexes of species similarity in the reproductive period are typical for the "Upper" and flooded peat quarries (Cj = 0,565), as well as flooded quarries and meadows (Cj = 0,301). In the latter case, the similarity is determined by common dendrophile species, which may indicate degradation of meadow bird communities. The floodplain of the middle reaches of the Zgar River inhabits 16 species of birds included in the Red Data Book of Ukraine, of which 7 were the nesting species or regularly registered in breeding period.

Authors: Bochani Nader , Hashemi Saeed
Published: April 2018

Ticks are arthropods that are the most important pests in the veterinary industry, which transmit important and dangerous diseases of humans and animals. Eyvan city located in the northern half of Ilam province and one of the most important centers of agriculture and animal husbandry is the province of Ilam. Hence, it is essential to identify the correct method for struggle tick and study the season's abundance and type of host. This study was carried out at the level of shambles in the city of Eyvan and from the first of April of 2016 to March of 2017. From the 1,500 sheep of different age, 220 viruses (14.66%) were infect with ticks. The average number of ticks in infected sheep was 2.9 ticks per sheep. The results showed that in sheep, 220 (38.66%) were male and 350 (61.40%) were female ticks. The tick identified on the sheep was related to 5 species and 3 ticks. The most frequency was related to the hyalomma genus, which includes Hyalomma asiaticum asiaticum (34.21%), Hyalomma anatolicum anatolicum (19.30%), also, the highest infection rate was in sheep in the city of Eyvan in June. In general, the prevalence and severity of infection were low but a relatively high species diversity was observed.

Published: April 2018

This research was designed with the aim of feasibility study on the production of safe fertilizers from urban sewage sludge in Isfahan refinery and assessment of the nutritional value of produced fertilizers in comparison with standard. For this purpose, the effects of different ratios of sewage sludge and manure on different treatments (including: 0, 25, 40, 55, 70 and 85 % wt/wt) along with 15 % bulking materials (including dry residues of Pine trees and grass waste) were tested in a randomized complete block design with three replications for a period of 75 days. Then, the nutrients content of each treatment was measured according to standard methods. The results showed that the concentration of heavy elements in the vermicompost produced in all treatments was lower than the standard recommended by EPA. The concentration of nutrients (total phosphorus and potassium, organic carbon, iron, zinc, copper, manganese) was very high in different treatments up to the application level of 70%. However, with increasing sludge consumption from 70% to 85%, the C / N ratio decreased significantly. Based on these results, an application of 70% sludge with 15% manure and 15% bulking material in a vermicompost production site can be used to produce a biological fertilizer with high fertilizer value and reduces the accumulation of sludge and environmental damage.

Published: April 2018

In modern agriculture, precise integrated management of farmlands requires natural, sustainable and environmentally friendly inputs replacing chemical fertilizers application. A two-year (2015-2016) field experiment was conducted to determine the influence of integrated application of wheat (Triticum aestivum L.) residues and compost accompanied by nitrogen (N) on growth, seed yield and yield components of sunflower (Helianthus annuus L.) at School of Agriculture, Shiraz University, Shiraz, Iran. The experiment was conducted at split plots arranged in randomized complete blocks design with three replications. Treatments included four N (0, 60, 120, and 180 kg N ha-1) two wheat residues (1.5 and 3 t ha-1), two municipal compost (50 and 70 t ha-1) rates and control (no additives). The results showed that higher N rates increased seed yield, whereas it reduced its oil content. Application of wheat residues and compost increased growth, seed yield, and seed oil content compared to control. The effect of compost application on seed yield increase was more pronounced than crop residues. Therefore, for an environmentally andagronomically sound management strategy, high compost application (70 t ha-1) combined with proper N fertilization is recommended for sunflower production in the region.

In carrying out mass explosions in quarries, a considerable amount of dust and gases is emitted into the atmosphere, more than in other technological processes of mining. The dusty cloud formed during the explosion pollutes the atmosphere not only of quarries and their industrial sites, but also the territory adjacent to them. However, the known methods and measures to reduce dust and gas emissions into the atmosphere during mass explosions have not solved this problem yet. In addition, the implementation of most methods involves certain financial costs. Therefore, the development of new ways to moisten career blocks with solutions of modern reagents produced in Ukraine is necessary and relevant. Considering the increase in the depth of quarries and, as a consequence, the extension of the length of quarry roads, the authors proved that these factors lead to an increase in the amount of dust formation from the road surface. In this regard, the solution of the problem of reducing the dust generation on the quarry roads is an important and relevant. This work is devoted to an experimental study of the determination of the effectiveness of the use of an aqueous solution of the surfactant "Leksol" to reduce dust emission during mass explosions and dust binding on the quarry roads. The problem is solved by means of industrial research to determine the effectiveness of reducing dust formation during mass explosions by pre-wetting quarry blocks with aqueous surfactant "Leksol" and binding dust on quarry roads during their watering with proposed aqueous reagent solution. The studies have confirmed the process of binding with surfactant "Leksol" of fine dust particles remaining on the surface of the quarry block after drilling on the surface thereof, and are actively involved in the overall process of formation of dust and gas cloud. At the concentration of the aqueous solution of the anti-dust reagent "Lexol-5" 5%, the average efficiency of dust suppression was 21%.

Authors: Yakymchuk R.A. , Valyuk V.F.
Published: April 2018

Frequency and spectrum of cytogenetic disorders in the cells of root meristem sprouts of Triticum aestivum L., induced by soil contamination with hexachlorobenzene in the territory of toxic waste ground and Dombrovskyi potassium ore mine (Kalush city, Ivano-Frankivsk oblast), were studied. The concentration of hexachlorobenzene exceeded MPC (maximum permissible concentration) by 1233.3–18350 times. It has been established that chemical soil contamination causes the increase of the frequency of cytogenetic aberrations by 1.8-3.8 times. Its highest indicators were found under the most intensive soil contamination with hexachlorobenzene in the areas of toxic waste ground which were not recultivated. Frequency of cytogenetic disorders exceeded the control level by 3.4-3.8 times. The maintenance of high mutagenic activity of hexachlorobenzene remains in the soil of the recultivated area of the ground is confirmed by statistically reliable increase of the number of aberrant cells by 2.6-3 times. It has been shown that soil contamination of Dombrovskyi mine with the complex of natural-mineral compounds of mining-chemical raw materials causes the increase of mutagenic activity level of low concentrations of chemical gene-toxic factors of techno-genic origin, which is seen in the induction of higher level of cytogenic disorders compared with spontaneous indicators by 1.8-2.4 times. Spectrum of chromosome aberrations, which mostly included acentric fragments, expanded due to induced bridges, ring chromosomes and micronuclei. The share increase of the cells with dicentrics, caused by the effect of soil contamination with hexachlorobenzene in the territory of toxic waste ground, confirms the radiomimetic effect, resulted from the effect of chemical mutagen in high concentrations. Chemical pollutants of the soil of all the studied areas show the ability to cause mitosis disorder, connected with the damage of mitotic apparatus. A significant increase of disorder frequency of chromosome segregation can be the result of the interaction of mutagens not only with microtube proteins of division spindle but also with heterochromatin of near-center areas of chromosomes, which is typical for the mechanism of the emergence of cytogenetic aberrations under the effect of chemical supermutagens in high concentrations. The increase of the cell number with multiple aberrations under the effect of soil contamination with hexachlorobenzene in different concentrations proves high gene-toxicity of the chemical compound and the threat of severe genetic outcomes when it gets into the environment.

Published: April 2018

The effect of herbicides (2,4-D, Roundup, Senkor) and surfactant sodium lauryl sulfate (pure and as part of detergents) on enzymes of energy pathways in the scaly carp's body was studied. Gills, brain, liver and white muscle were selected for the analysis. To determine the levels of activity of enzymes in energy metabolism, lactate dehydrogenase (EC 1.1.1.27) and glucose-6-phosphate dehydrogenase (EC 1.1.1.49) in the cytoplasmic fraction and isocitrate dehydrogenase (EC 1.1.1.42) in the mitochondrial fraction were studied. The research found that sodium lauryl sulfate, both pure and in a synthetic detergent, increase the activity of enzymes in all experimental groups. Effect of herbicides was ambiguous. Under the influence of Sencor the activity of enzymes increases in all tissues. Roundup causes inhibition of enzymes in the brain, but there is an increase in the activity of enzymes in other tissues under the influence of this toxicant. The influence of 2,4-D causes increased activity of isocitrate dehydrogenase in all experimental groups, as well as the activity of lactate dehydrogenase in the brain and the liver increases, whereas in gills and white muscle it decreases. The activity of glucose-6-phosphate dehydrogenase by the impact of 2,4-D was decreased only in the liver, in other groups - was increased. The investigations may be evidence of adaptive alterations in energy metabolism aimed at the survival of fish under conditions of herbicides and surfactants toxic effects. Also increase the activity of enzymes can be related to detoxification processes occurring in the body and require additional energy consumption. The article presents the results of the study of the influence of herbicides (2,4-D, Zenkor, Roundup) and surfactant the sodium laurylsulfate (pure and as a part of the synthetic detergent) on the activity of lactate dehydrogenase, isocitrate dehydrogenase, glucose-6-phosphate dehydrogenase in the liver, gills, brain and white muscle of scaly carp (Cyprinus carpio L.). Human impact on water forcing fish to use various mechanisms of adaptation to the changed environmental conditions. Knowledge about the features of the receipt, distribution, accumulation of xenobiotics in organs and tissues, biochemical changes as a result of poisoning can be used to find out the mechanisms of fish's adaptation to toxicants, for identify the causes of death of hydrobionts in natural waters and to justify methods of controlling environmental pollution. The results of the research show that the influence of herbicides and surfactants causes significant changes in the processes of energy metabolism of scaly carp.

Over the past decade, Ukraine has been one of the leaders in exporting honey to EU countries. The main obstacle to increasing the export of Ukrainian honey to EU countries is the discrepancy of honey safety indicators with the requirements of importing countries. This is due to the use of a significant number of drugs with antimicrobial spectrum of action in the treatment and prevention of diseases of bees, the remains of which fall into honey. In domestic honey, according to recent data, the remains of such groups of antibiotics and antimicrobial agents as chloramphenicol, nitrofuran, nitroimidazole, sulfanilamides, tetracyclines and aminoglycosides are most commonly found.The nitrofurans, which are quite stable, can be stored in honey for a long time and are not destroyed even at high temperatures. Therefore, the urgent question remains the development and introduction into practice of laboratory analysis of a sensitive and reliable method for determining the residual amounts of nitrofurans in honey.The method developed by us allows us to determine the residual amounts of metabolites of nitrofurans in honey, namely: furazolidone derivative - 3-amino-2-oxazolidinone (AOZ), furaltadone-3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), nitrofurase-semicarbazide SEM) and nitrofurantoin-1-aminohydandomine (AHD).The use of drugs nitrofuran number in the treatment and prevention of infectious diseases of bees involves the receipt of their metabolites in honey in the human body.The conducted studies revealed that nitrofurantoin (38% of honey samples) was used most often in beekeeping, followed by fureladone (24%), while nitrofurase and furazolidone were used equally in 19% of honey samples, respectively.The conducted studies revealed 4 metabolites of nitrofurans in natural honey, namely the metabolite furazolidone 3-amino-2-oxazolidinone (AOZ), nitrofurase-semicarbazide (SEM), furaltadone-3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), and nitrofurantoin - 1-aminohydandomine (AHD).The content of 3-amino-2-oxazolidinone (AOZ) and semicarbazide (SEM) in honey exceeds the MDR by the norms of Ukraine. According to EU norms, the content of 3-amino-2-oxazolidinone (AOZ), 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ) and 1-aminohydinotin (AHD) in honey exceeds MDR and the semicarbazide content (SEM) permissible concentration.
On Three Types of Empathy: the Perfect, the Truncated, and the Contaminated
Authors: Załuski Wojciech
Published: April 2018

In the paper a distinction is made between perfect empathy, truncated empathy, and contaminated empathy. Perfect empathy is defined as the combination of three elements: cognitive empathy (the capacity for a comprehensive and ethically proper understanding of other people’s emotions), affective empathy (the tendency to emotionally respond to other people’s emotions in an adequate way: sorrow to sorrow, and joy to joy), and a tendency to undertake an ethically proper action (e.g., to relieve the sufferer’s pain) as a result of the emotional response to other people’s emotions. The phrase ‘ethically proper’ in the above definitions shows that perfect empathy is not a free-standing ethical capacity. An empathic emotional reaction and empathic action are justified only if they are based on the comprehensive and the ethically proper understanding of the other person’s emotion, i.e., the understanding which enables one to assess whether this emotion is justified by its causes. But such an understanding is impossible without a sense of justice, or more generally, without the knowledge of ethical rules which say in whatcircumstances an emotion of sorrow or joy is justifiable, and, additionally, what action is ethically proper in a given situation. Truncated empathy, which may take various forms, lacks one of the free elements of perfect empathy. Finally, contaminated empathy arises by admixing one of the four following amoral or non-moral elements to perfect or truncated empathy, namely: thankfulness at the contrast between our fortune and the sufferer’s misfortune; the feeling of anxiety, arising at the sight of the sufferer’s misfortune, about our own good future; the unpleasant feeling of distress, arising at the sight of the sufferer’s sorrow; or pity.
Fenomen zerwania
Authors: Karpiński Piotr
Published: April 2018

Przedmiotem artykułu jest zbadanie i opis sytuacji, kiedy ktoś w imię przekonań, opinii, poglądów decyduje się zakończyć relację z drugim człowiekiem. Sytuację taką nazywamy fenomenem zerwania. Zerwania mogą być różne: chłopak zrywa z dziewczyną, małżonkowie decydują się na rozwód, ktoś zrywa umowę albo przyjaźń. Z wszystkich tego typu sytuacji interesuje nas tylko zerwanie z powodu różnicy w wyznawanych poglądach. Fenomen zerwania w takiej sytuacji przybiera kształt sporu o to, co ważniejsze – prawda czy osoba. Jak to się dzieje, że w imię prawdy odrzucam osobę? Czy w imię relacji z drugim mogę zdradzić prawdę? Czy wartością ważniejszą jest prawda czy Ty? A może zerwanie jest symptomem nierozwiązanego stosunku do Absolutu? Odpowiedzi na te pytania szukamy, odwołując się do myśli Józefa Tischnera i innych współczesnych filozofów. Zarysowane zostają dwa skrajne stanowiska: prawda ponad osobą oraz osoba ponad prawdą. Wyznaczają one dwa odmienne paradygmaty myślenia: monologiczny i dialogiczny. Problem zostaje rozważony także w płaszczyźnie aksjologicznej, gdzie prawda i Ty jawią się jako wartości. W zerwaniu istotne jest utożsamienie Ja z daną prawdą – następują tu procesy solidaryzacji egotycznej i absolutyzacji Ja. W ich efekcie zerwanie można opisać za pomocą Tischnerowskiej kategorii potępienia i mechanizmu władzy. Na końcu zostaje ukazana możliwość rozwiązania sytuacji zerwania przez miłość.
A conceptual constitutive model unifying slurried (saturated), compacted (unsaturated) and dry states
Authors: Pedrotti M. , Tarantino A.
Published: April 2018

Reconstituted and compacted soils are commonly assumed to exhibit a fundamentally different behaviour due to different microstructure. However, inspection of pore size distribution of the same soil in compacted and reconstituted states suggests that the boundary between these two states is more blurred. This paper explores the continuity between the microstructure of reconstituted and compacted states of kaolin clay and formulates a conceptual constitutive model unifying these states. Clay samples were prepared by saturating the pore space with different fluids (water, acetone and air) and the effect of pore-fluid fraction on the micro- and macroscale response of the clay was investigated experimentally. A conceptual constitutive model for unsaturated clays for quasi-isotropic stress states was therefore formulated, which allows the modelling of various unsaturated hydro-mechanical paths based on constitutive parameters only derived from the compression behaviour of clay under dry and saturated conditions (testing on samples formed from dry powder and slurry, respectively).
It Is More Than Just the Message: Presentation Effects in Scoring Writing

Published: April 2018

People write for many reasons. Writing is used as a tool to record ideas and information, communicate with others, chronicle experiences, express one's feelings, persuade others, facilitate learning, create imagined worlds, and evaluate students' competence (Graham, 2006). In some instances, the only intended reader of a piece of writing is the author. Examples of such writing include diaries, to do lists, and lecture notes. In other instances, writing is meant to be both read and formally evaluated by others. This kind of writing can range from term papers to state and federal writing assessments to writing requirements included as part of college entrance applications.
Stepping in the Same Stream Twice: A Dynamic Systems Look at Group Work in the ESL Classroom
Authors: Blackman Perrin
Published: April 2018

The beauty of teaching is that no matter how many times you have taught the same course, you cannot go back and re-teach any class, even if you wish you could. Each class moves along in its own way like a stream, following a fairly predictable path while taking surprising (yet logical) turns and twists over time. Time, as far as we know, is irreversible, but by looking at your classroom as an open, self-organizing system whose flow emerges as it progresses, you can prepare for the next class by making some very effective changes – changes that may seem small but that have a significant impact on the identity of the class and the flow of learning that emerges over time.

When I was 12, I wanted a diary with a lock and key; the kind little sisters can’t get into. Later in my teen years, I used to write each day’s event in a small calendar. Throughout the years I have seen the value of journaling in my own life and more recently I have read articles about its benefits in a classroom. Therefore, when my students in Reading and Writing level 2 said they wanted to write more, I thought this might be a good idea. So, armed with small blue exam books and markers for their names, I explained to my class what we were going to do.

Published: April 2018

In recent years, bicycle races, along with the crest of the high technology continues to increase. Because of this increased races, performance of bicycles, in both biological and mechanical terms, is extraordinarily important and efficient. In terms of the ratio of cargo weight a bicycle can carry to total weight, it is also a most efficient means of cargo transportation. In spite of advanced technology, there are still some problems on bicycles during working conditions and road roughness such as on the mountain from tire and mechanical parts. In this investigation, a extraordinary designed with fiber-carbon body and light bicycle is tested on mountain road conditionswith prescribed trajectory on the mountain for different elevation, speed, hearth rate, bike cadence and average temperature. The real time measured parameters are predicted with proposed two types of neural networks for approaching real time neural network predictors. The results of the proposed neural network have shown that neural predictor has superior performance to adopt the real time bicycle performance.

Authors: Guimarães Gustavo Cerqueira , Schlee Aldyr Garcia , Piazzi Giulia
Published: April 2018

Conversa com o escritor, desenhista, criador da camisa Canarinho, jornalista e professor gaúcho Aldyr Schlee, realizada por Gustavo Cerqueira e editada por ele, em parceria com Giulia Piazzi. No diálogo do escritor com a revista FuLiA / UFMG, bem como em sua obra ficcional, o futebol é colocado diretamente em contato com questões relativas ao local e às fronteiras (Jaguarão/Brasil e Río Branco/Uruguai) e com os desvios e desencaixes identitários evocados por meio de flashes autobiográficos tanto do entrevistado quanto do entrevistador (Lajinha/MG e Ibatiba/ES).
Consolidação do futebol em Belo Horizonte e as conexões de seu meio esportivo (1904-1921)
Authors: Ribeiro Raphael Rajão
Published: April 2018

Assim como nas principais cidades do Brasil, a introdução do futebol em Belo Horizonte se deu de forma independente e seguiu dinâmica própria. Contudo, o meio esportivo local não estava alheio ao que se passava em outras localidades, estabelecendo uma série de conexões ao longo da consolidação dessa prática. O presente texto objetiva mapear as articulações promovidas durante esse processo, por meio da circulação de informações, pessoas e mercadorias, nas duas primeiras décadas de desenvolvimento dessa modalidade atlética na capital mineira. Novidades tecnológicas, criação de mercados consumidores, tentativas de institucionalização, intercâmbios de experiências e embates entre diferentes realidades articularam-se num fenômeno inicial de integração regional e nacional que revelava a força dos localismos na composição dos campos esportivos do primeiro quartel do século XX.
Dermatoglyphics pattern in children with congenital malformations
Authors: T. Udhaya Deepa , G. Durai Arasan
Published: April 2018

Background: Dermatoglyphics is an indispensable tool in the field of Forensic Science and Criminology and its various unknown aspects are being explored in other fields. They are important in genetics because of their usefulness in diagnosing some dysmorphic syndromes like Down Syndrome, Turner Syndrome etc.Methods: A hospital based descriptive study was carried out in the Institute of Child Health, Madras Medical College, Chennai from January 2015 to September 2015. Children admitted with major congenital malformation diagnosed either clinically or with imaging were included in the study.Results: 125 children with congenital malformation were included in the study. This included 65 cases of congenital heart disease, 20 cases of congenital talipo equino varus, 15 cases of cleft lip/palate, 15 cases of genetic syndrome and 10 cases of CNS malformations. Loops (64.3%) were the most common pattern in CHD followed by whorls (31.5%). In the CTEV group, loops (57.65%) were the most common pattern followed by whorls (36.48%). Ulnar loops (50.32%) was more common in Down’s Syndrome whereas arches (46.37%) were more common in Edward’s Syndrome. Frequency of whorls (53.28%) was higher in children with CNS malformations.Conclusions: Congenital malformations are associated with abnormal dermatoglyphics patterns. Patterns such as loops are common in CHD and syndromic children whereas whorls are common in children with CNS malformations. Large population study with a well-matched control may bring out definite dermatoglyphic pattern for many congenital disorders. They may serve as a simple diagnostic tool for these disorders.

Authors: Medeiros Cássio Ilan Soares , Silva Daniele De Figuêredo , De Oliveira Filho Abrahão Alves , Lima Edeltrudes De Oliveira
Published: April 2018

Os monoterpenos são uma classe de metabolitos secundários de plantas conhecidas por apresentar uma variedade de efeitos em diferentes sistemas biológicos. Portanto, o objetivo deste estudo foi avaliar os efeitos farmacológicos e toxicológicos dos enantiômeros (R)-(+)- e (S)-(-)-citronelal in sílico. Cerca de 50% das razões que levam à insuficiência no desenvolvimento de um fármaco estão associados com o perfil farmacocinético e toxicológico. Assim, a determinação do perfil farmacocinético (ADME) juntamente com a toxicidade (ADMET) são parâmetros importantes na definição de biodisponibilidade e efeitos tóxicos de uma molécula. Os softwares Pass online, Osiris e Molinspiration foram utilizados no estudo para atividades in sílico. Modelos in sílico são aplicados para a avaliação da toxicidade de compostos em ambientes metabólicos de mamíferos. Os resultados obtidos mostraram que as moléculas foram semelhantes a fármacos com 29 possíveis atividades com Pa > 70% e estes monoterpenos apresentaram baixo risco de toxicidade teórica.

No ano de 2005, aconteceu a primeira edição de uma das olimpíadas brasileiras de maior destaque nacional, abrangendo milhões de estudantes a cada ano, a OBMEP (Olimpíada Brasileira de Matemática das Escolas Públicas), promovida pelo Ministério da Educação (MEC) e pelo Ministério da Ciência e Tecnologia (MCT) com o apoio do Instituto de Matemática Pura e Aplicada (IMPA) e pela Sociedade Brasileira de Matemática (SBM), sendo estes responsáveis por sua organização e direção, possuindo como principais objetivos o estímulo ao estudo da matemática, a melhoria do ensino em todo país, aperfeiçoamento e valorização profissional dos professores, entre outros fatores. Nesse sentido, este estudo teve como objetivo analisar às principais características dessa olimpíada, dando ênfase aos resultados obtidos por uma cidade do interior nordestino, Paulista, Paraíba, durante as dez primeiras edições da OBMEP, visto que, nos últimos anos, os estudantes paulistenses conseguiram um grande destaque na mídia brasileira, devido às premiações alcançadas que, superaram outras cidades economicamente mais evoluídas do estado. Foram realizadas entrevistas com 03 (três) alunos que obtiveram premiações nessa olimpíada, e também, com a professora representante da OBMEP na cidade, com o intuito de obter informações em relação aos estudos preparatórios dos estudantes para a realização da mesma, além da coleta e verificação dos dados obtidos durante algumas edições da OBMEP em Paulista-PB. Houve uma grande mudança na elaboração das aulas de matemática, que se tornaram mais práticas e relacionadas ao cotidiano dos discentes, além disso, os projetos extracurriculares contribuíram para a dedicação e sucesso dos alunos nessas competições matemáticas.
Metodologia para Modelagem de Conversores Utilizando o Circuito Equivalente de Thévenin
Authors: Berger Felipe , Salvador Marcos A. , Pereira Thiago A. , Lazzarin Telles B. , Coelho Roberto F.
Published: April 2018

Este artigo apresenta uma nova metodologia aplicada como ferramenta à modelagem de conversores estáticos. A metodologia permite representar tais conversores por meio de um circuito equivalente de Thévenin visto a partir do par de terminais que contém o elemento cuja tensão ou corrente se deseja controlar, apresentado como principal vantagem a versatilidade com que as funções de transferências podem ser obtidas. A partir da análise de um circuito equivalente de Thévenin literal encontram-se modelos válidos para todos os conversores, distinguidos apenas pelas equações que descrevem os parâmetros VTH e ZTH de cada caso. A fim de validar a metodologia proposta, as funções de transferência orientadas ao controle de tensão e da corrente dos seis conversores cc-cc básicos não isolados são obtidas e validadas via simulação por meio da resposta ao degrau. Resultados experimentais referentes ao conversor Boost também são apresentados.

Published: April 2018

Neste trabalho são avaliados alguns dos principais algoritmos de anti- ilhamento, com modelos em ambiente MatLab/Simulink®, a partir de um inversor fonte de tensão monofásico projetado para injetar potência ativa na rede de distribuição em baixa tensão, utilizando como fonte primária energia solar fotovoltaica. Os testes são realizados empregando uma carga RLC em paralelo, com fator de qualidade e frequência de ressonância projetados de modo a atender às exigências da norma NBR IEC 62116. Uma vez que os métodos passivos para detecção do ilhamento não possuem boa eficácia e, que os métodos remotos são dispendiosos economicamente, este trabalho tem seu foco nos métodos ativos. Normalmente, uma estratégia híbrida, que contempla um algoritmo ativo e proteções de sub/sobretensão e sub/sobrefrequência é escolhida para compor a estratégia de anti-ilhamento. Finalmente, um protótipo de 1 kW é utilizado para os testes experimentais de uma das estratégias de anti-ilhamento.
Estratégia de Paralelismo Baseado no Conceito de Impedância Virtual para Inversores Trifásicos a Quatro Fios
Authors: Arbugeri Cesar A. , Jappe Tiago K. , Lazzarin Telles B. , Mussa Samir A.
Published: April 2018

O artigo propõe uma estratégia para a conexão em paralelo de inversores trifásicos, a qual pode ser aplicada em sistemas baseados em fontes de alimentação ininterrupta (conhecidas como UPS – Uninterruptible Power Supply). A estratégia de controle proposta é baseada no conceito de impedância virtual e sem comunicação entre os módulos. A principal característica da proposta é a simplicidade de implementação, que é similar às abordagens convencionais de modulação e controle de inversores trifásicos. As principais vantagens obtidas são a modularidade, a rápida resposta dinâmica e a boa regulação estática dos conversores, mesmo durante ocorrências de distúrbios de carga ou de eventos de conexão/desconexão de inversores da associação em paralelo. O procedimento de implementação digital é elucidado, assim como os resultados da validação experimental, com base em dois módulos trifásicos, à quatro fios, com potência individual de 6 kVA.
Los trastornos del sueño y su compleja relación con las funciones cognitivas.
Authors: Lira David , Custodio Nilton
Published: April 2018

El sueño es una necesidad fisiológica que juega múltiples roles en los seres humanos y presenta características especiales que van variando con la edad y el medio ambiente. Es regulado mediante neurotransmisores cerebrales y a través de ritmos biológicos intrínsecos de carácter periódico (ritmo circadiano), que se manifiestan con intervalos de 24 horas y que regulan el ciclo vigilia-sueño. La exposición a la luz artificial por la noche, así como el acelerado ritmo de la vida moderna contribuyen al aumento de la prevalencia de los trastornos de sueño, que podrían afectar las funciones cognitivas mediante diversos mecanismos fisiopatológicos, en diferentes periodos etarios, en especial en niños pequeños y en adultos mayores. Es indispensable llevar a cabo estudios de investigación que permitan determinar los factores del sueño que incrementan el compromiso cognitivo y proponer medidas de prevención que puedan implementarse adecuadamente.
