Authors: Castilho Giovana Rodrigues , Proença Marcelo Carlos de
Published: June 2018

O objetivo do artigo foi investigar o conhecimento sobre o conceito e o ensino de polígono. Participaram do estudo dois estudantes do quarto ano de um curso de licenciatura em Matemática de uma universidade pública do interior do estado do Paraná. Após serem selecionados a partir de um teste conceitual, participaram de uma entrevista individual e áudio-gravada. Os resultados mostraram que a estudante do curso noturno possuía pouco conhecimento sobre o conceito de polígono em termo de seus atributos definidores. Possuía, sobretudo, pouco conhecimento para exercer um ensino organizado, pois possivelmente realizaria o modo tradicional aprendido na escola. Por outro lado, os resultados mostraram que a estudante do curso integral apresentou conhecimento adequado sobre os aspectos envolvendo os atributos definidores e irrelevantes e sobre os exemplos e não exemplos de polígono. Apresentou, sobretudo, conhecimento sobre o ensino de polígono que valorizou esses aspectos no ensino.

Authors: Corinaldesi Valeria , Donnini Jacopo , Merlonetti Glauco
Published: June 2018

The aim of this experimental activity was to study the early-age behavior of several Fiber-Reinforced Concretes (FRCs) containing expansive agent. The investigation concerned the evaluation of the influence of different amounts of fibers (dosages of 2.0%, 1.75% and 1.5% by volume of FRCC) on the mechanical performance of FRCs. In particular, hooked brass-coated fibers were used and dead-burnt calcium oxide based expansive agent was employed at a dosage of 40 kg/m3. The attention was focused on the strength development at early ages. Mechanical tests were carried out at 0.25 (i.e. 6 hours, that is time of demolding), 1, 2, 7 up to 28 days of curing. The properties of FRCs were characterized at the fresh state, by measuring flow ability and consistency as well as at hardened state by measuring compressive and flexural strength up to 28 days. Flexural strength was measured on prismatic specimens according to the procedure described in EN 12390-5. The different dosage of fibers did not influence the values of compressive strength, while there is a significant difference in terms of 28-day flexural strength between the several mixtures depending on the different amount of fibers. In all cases at least 20 MPa of 28-day peak flexural strength were achieved.

Authors: Liesl le Roux Corlise
Published: June 2018

Co-movement and volatility analysis between variables are an important considerations in investment related decisions. The relationships of spot and two future priced sugar contracts are examined against the currency and main index of Brazil, China, Colombia, India, Indonesia, Mexico, Pakistan, Philippines and Thailand. Sugar which is produced in many countries around the world is the world's largest crop by production in metric tons. Co-movement and volatility analysis includes correlation, vector autoregression, Johansen cointegration test, impulse responses, pairwise Granger causality test and three GARCH models. The three GARCH models are the GARCH, GJR-GARCH and EGARCH models. A long run relationships exists between the three sugar variables, the three sugar variables and the Shanghai SE A Share Index; as well as between the tree sugar variables and the Thai Bhat. Co-movement results indicate that unidirectional and bidirectional relationships exist among the variables. A bi-directional relationship exists between sugar spot and CSCE sugar 11 future as well as between sugar spot and Liffe sugar future. Sugar spot and sugar future have a uni-directional relationship with the indices of Bangkok, Indonesia, Philippines, China, and India. Sugar spot and sugar futures Granger causes the currencies of Brazil, Colombia, Indonesia, Philippines, Thailand and India. The volatility analysis done shows that the AIC and SIC results of the GARCH models which indicates that the original GARCH model fits the data the best for sugar spot and the CSCE sugar 11 future. The EGARCH model fits the data the best for Liffe sugar future.
Efficacy of Rehabilitation Measures on the Functional Development of Children with Spastic Cerebral Palsy
Authors: A Dinakaran
Published: June 2018

Background: Spastic cerebral palsy (CP) is the most common type of CP. Up to 80% of all Individuals with cerebral palsy suffer from some degree of spasticity. Spasticity adversely affects muscles and joints of the extremities, causing abnormal movements, and it is especially harmful in growing children.

Cerebral palsy (CP) is a syndrome of motor impairment that results from a lesion occurring in the developing brain. The degree of spasticity can vary from mild muscle stiffness to severe, painful, and uncontrollable muscle spasms .Normally; muscles must have enough tone to maintain posture or movement against the force of gravity while at the same time providing flexibility and speed of movement.

Spasticity is a velocity-dependent increase in resistance of a muscle when the muscle is moved passively or stretched. Individuals with spastic CP experience stiffness in affected limbs due to focal muscular hyperactivity, resulting in limited or awkward movements.

In this research work Quasi experimental design was adopted for Pre- assessment of physical and functional status of children with cerebral palsy assessed by appropriate tools and the results discussed in detailed in different sections of the paper.

Published: June 2018

It is shown that the improvement of the environment can be achieved by using the adsorption properties of leaves of woody plants, which are able to absorb the exhaust gases from vehicles, industrial plants, dust and vapors from air. The number of toxic influence of heavy metals on vegetable plants was established with good indicative properties: Cd > Ni >Pb. Accumulation of heavy metals, leaves of the juniper have any symptoms of poisoning, inhibition of root growth, formation of necrosis, dwarfism, wilting, dropping foliage, etc, especially in leaves exposed to cadmium. Different kinds of heavy metals have their own specifics, which defining the maximum level of exposure in the investigated samples. Virtually all heavy metal compounds are toxic and have carcinogenic effect.It should be noted that the main source of it are the smokestacks of factories, the industrial enterprises and exhaust gases from vehicles. If there is an excess of heavy metals, occur symptoms on plants - growth noticeably slows, getting a dwarf form.Thus, on the basis of obtained date, we get conclusion, that the accumulation of heavy metals by leaves of woody plants, in our casejuniper and oak, is due to the passage of the adsorption process of toxic metals contained in the air basin.

Authors: S Mohanapriya , V Raj
Published: June 2018

In this study, poly vinyl alcohol and pectin are in situ cross-linked using dual cross-linker comprising a mixture of sulfosuccinic acid and glutaraldehyde followed by solvent casting.Titanium dioxide nanoparticles are incorporated into polymer solutions that controls alignment and disentanglement of polymer chains at molecular level. It is shown that rational design of membrane microstructure with proper arrangement of hydrophobic and hydrophilic domains has been formulated by blending PVA with PC. Water sorption through nanocomposite membrane enhanced when optimum quantity of titanium dioxide particles are present. In addition, titanium dioxide nanoparticles help to provide more inter-connected proton conducting pathways and acts as reinforcing units. Through the hydrogen bonds formed between surface functional groups of titanium oxide nanoparticles and polymer chains, protons are transferred through the membrane both by hopping and vehicular mechanisms. Titanium dioxide nanoparticles also act as fillers and effectively prevent the methanol permeation. Polymer voids are occupied by the presence of Titanium dioxide nanoparticles that selectively allow protons to pass through form anode to cathode side. Both improved proton conductance and lower methanol permeability, electrochemical selectivity of nano Titanium dioxide modified PVA-Pectin polymer electrolyte membrane is enhanced. With further enriched proton conductivity by the presence of titanium dioxide nanoparticles, fabricated pectin polyvinyl alcohol hybrid nanocomposite membrane exhibit higher electrochemical selective factor.
Fast Recovery Architecture by Selecting Surrogate Master Node (FSMN) in Industrial IoT Environment
Authors: Roh Taekyun , Lee Sooyeon , Chung Tai-myoung
Published: June 2018

This paper proposes an architecture that selects a sink node when a CPS is paralyzed. The CPS is a system (master node) with various sensor networks and machine networks that exchanges device information in real-time in the industrial IoT environment. When the CPS cannot perform normally due to internal/external factors, the last log of the master node is analyzed to determine the cause of the paralysis. The CPS select six attributes from the log data and convert them into datasets usable in this architecture. The normal category of the sink node is determined through the K-means clustering algorithm according to the sink node's profiling data. The centroid of the normal category is then determined. The normal category of the sink node is updated in real time until the CPS is paralyzed. When CPS paralysis occurs, the log data of the most recent sink node is applied to the K-means clustering that was formed in advance. We then determine the most available sink node among the sink nodes through the distance using vector value and priority algorithm between the central point and the sink node. Therefore, in the case of a failure of the master node, the high-priority surrogate master node can perform the role of the master node so that the data and the system can be maintained even in unexpected situations.

On the Dialogue of Aesthetics and Philosophical Anthropology
Authors: APOSTOLOPOULOU Georgia
Published: June 2018

After the alleged ‘ends’ of metaphysics, of history, and of art, aesthetics reorganises the field of its enquiry. While retaining the question of the meaning of art for the human as the background justification of its theorising, aesthetics meets philosophical anthropology and enlarges its field. Philosophical anthropology explains that the instability of the human condition demands culture as the artificial stabilisation of the human world as well as of the human in the world. Expressivity, artificiality, and the aesthetic are interweaved with the meaning of the human world. In this context, pictures have priority over concepts and justify art as the eminent pictorial form of meaning. Since the human lives in nature and culture, the stabilisation of its open world is possible through creation of spatial correlates and of objects as well. Thus, aesthetics does need to expand enquiry beyond the discourse on art, so that it includes the issues concerning the aesthetic character of the human world and its spatial correlates. While Wolfgang Welsch and Richard Shusterman argue for a revision of aesthetics, Joseph Margolis and Helmuth Plessner support the stronger dialogue between philosophical anthropology and aesthetics in different ways. Further, Arnold Berleant explores aesthetics of human space.
How Much is an Image Worth?
Authors: BAZAC Ana
Published: June 2018

The paper discusses the problem of “competition” between the image and the articulated language/text. The problem as such is historical and it reflects the change between the language based communication (including the radio era) and the mainly image based communication.  Opposing to those who equate the image construction in the information and communication technology with the impoverishment of meanings and necessity and ability of logical/rational discourse, the arguments of these two positions are analysed.   The paper mentions the difference between representation, image and idea, analyses some arguments related to the logical articulation of words in texts, and to the specific imagistic manner of communication, and concludes that the text and image are complimentary, and that their worth depends on the meanings they transmit and the quality of meanings/values they transmit. In this respect, the diminishing of preoccupations, of ability and time for logical articulation of the reference to the world means the decline of man. At the same time, the theory highlighted in the paper does not counter the “bad” image to the “good” text (and certainly, nor vice versa), but the measure in their use according to the scale of goals and means which people must have.
On the Complex Emotion: Be Physiological, Cognitive or Situated?
Authors: TAO Lin , TANG Haijun , ZOU Mingzhuo
Published: June 2018

The topic emotion in traditional philosophy is discussed fragmentarily. And in recent years, there are two important approaches to analyze emotions, namely neo-Jamesianism and cognitive theory of emotion. Neo-Jamesians identify emotions with states of bodily arousal, which is determined by the nerve and occurs because of the feelings of bodily changes. And the cognitivists identify emotions with representations of evaluative judgments, which is regarded as propositional content accepted or affirmed by their subjects. Besides, the situated theory suggests we should expand our attention to the cultural and social environment in which emotions are moulded.

Some Remarks on the First Book of Aristotle’s Politics
Authors: MISHURIN Alexander
Published: June 2018

This article is devoted to a sequential analysis of the first book of Aristotle’s Politics. It suggests an interpretation of the classical problem of natural hierarchy of men as it described in the first book of the treatise. In this book, Aristotle examines seven commonly held definitions of a slave – four “natural” and three “conventional” ones – and then offers his own eighth definition, placed right in the middle between nature and convention. The article exclusively deals with the first book of Politics and avoids invoking other books of the treatise as well as other works of Aristotle because in classical political philosophy every statement is highly contextualized and could not be simply quoted in order to prove or disprove any point of view without preceding deep examination.
Effect of Pulsed Ultraviolet Light on Natural Microbial Load and Antioxidant Properties of Fresh Blueberries
Authors: Guner Senem , Topalcengiz Zeynal
Published: June 2018

Blueberries have been drawn more attention in recent years for their antioxidant capacities and proposed health benefits. Pulsed ultraviolet (PUV) light is known for its disinfection effects on the surface of fresh fruits. This study‘s aim was to examine the effects of PUV light on naturally present microbial load, antioxidant capacity, and antioxidant enzyme activity of fresh blueberries. Fresh blueberry samples were treated for 30, 60, 90, and 120 s. Samples were stabilized at 13 cm away from the PUV lamp before treatment. Total Aerobic Plate Count (TAPC) and yeast and mold count reduction were observed the highest in samples treated for 90 s, 1.97 and 1.27 log CFU/g, respectively. Antioxidant capacity levels were significantly different for treated samples for 60 and 90 s in FRAP analysis, whereas no differences were observed in results of DPPH analysis. Superoxide dismutase (SOD) activity as antioxidant enzyme had no difference, however, glutathione peroxidase (GPx) increased by 50% with PUV treatment for 120 s. PUV light treatment of fresh blueberries for 90 s was determined as ideal exposure time among tested time intervals of this study. PUV light illumination can generally enhance antioxidant capacity and antioxidant enzyme activity of fresh blueberries and decrease the population of natural microorganisms of fresh blueberries and similar small fruits.

Bu araştırma; gelişmişlik düzeyi farklı bölgelerde, değişik yaş, gelir, eğitim düzeyi ve meslek gruplarındaki tüketicilerin, etlik piliç eti tüketim tercihleri üzerine medyanın etkisini belirlemek amacıyla yapılmıştır. Bu amaçla, Kayseri, Sivas ve Yozgat illerinde (TR 72 Bölgesi) bulunan üç ilde toplam 1350 (Kayseri 500, Sivas 450, Yozgat 400) örnekleme yüz yüze anket uygulaması yapılmıştır. Çalışmada, örnek hacmi ana kitle oranlarına dayalı tek aşamalı basit tesadüfî örnekleme yöntemi ile belirlenmiştir. Tavukçulukla ilgili olumsuz medya haberlerinin tavukçuluk ürünlerinin tüketimi üzerine etkisinin değişimi TR72 bölgesi bazında incelenmiştir. Tüketicilerin tavukçulukla ilgili haberleri takip etme oranı bakımından her üç il birbirinden önemli derecede farklılıklar göstermiş olup, genel durumuna bakıldığında bireylerin yaklaşık %75‘i, tavukçulukla ilgili haberleri takip etmektedir. Etlik piliçlerin beslenmesinin sağlıklı olmadığını düşünenlerin oranı ortalama %60,4 olup, bu değer bakımından bölgesel farklılıklar önemli bulunmuştur. Medya haberlerinden etkilenerek tavuk eti tüketimini miktarını azaltanların oranı %36,1 olup, bu oran bakımından bölgesel farklılıklar önemli olarak gerçekleşmiştir. Son yıllarda et tüketimi tercihleri üzerine medyanın etkisi bölgelere, eğitim düzeyine ve meslek gruplarına göre farklılık göstermiştir. Tavuk eti tüketimini etkileyen faktörler bakımından ise bölgelere, eğitim düzeyine, meslek gruplarına ve gelir gruplarına göre önemli farklılıkla hesaplanmıştır. Tavukçuluk sektörü hakkında medyada çıkan olumsuz haberlerin bu alanda pazarlama sorunları oluşturacak düzeyde etkili olduğu, tüketicilerin bu haberleri yüksek oranda takip ettiği, buna karşılık yine medya araçları kullanılarak daha etkin tanıtım ve bilgilendirmenin yapılması gerektiği sonucuna varılmıştır.
COMPETITIVE PRESSURES ON THE ARTISAN COFFEE ROASTER SEGMENT IN THE STATE OF MINAS GERAIS, BRAZIL: A MULTI-CASE STUDY
Authors: Guimarães Elisa Reis , De Andrade Helga Cristina Carvalho , Cozadi Álvaro Dos Reis , Antonialli Luiz Marcelo , Dos Santos Antônio Carlos
Published: June 2018

The specialty coffee market is still little known and underexplored in Brazil, motivating an analysis of the competitive pressures and structure of the artisan coffee roaster segment in the state of Minas Gerais, in order to better understand it and encourage the adoption of specific policies for its expansion, besides comparing it to the commodity coffee roasting segment. A multi-case study was performed with three companies in this segment through in-depth interviews with their owners. There were significant changes in the competitive forces that shape the coffee industry, when comparing the specialty and commodity coffee segments, both in intensity and in motivations. Among the suggested policies to support the specialty coffee segment are its promotion and dissemination through “consumer education” and awareness raising on the differentiated properties of these products, besides providing subsidized courses and specializations for those who wish to be involved in this marketplace.

Authors: Terra Willian César , Pereira da Silva Júlio Carlos , Campos Vicente Paulo , Salgado Sônia Maria De Lima
Published: June 2018

Understanding the mechanisms of plant-parasitic nematodes (PPN) dispersion is vital to improve control strategies aiming to restrict dissemination of these plant parasites. In the present work, we evaluated the presence of PPN in Arabic coffee (Coffea arabica) seedlings produced in commercial nurseries in Minas Gerais, state, Brazil. A total of 2830 samples obtained from 318 coffee nurseries, in 84 counties within the South and Zona da Mata regions in Minas Gerais, Brazil and representing more than 62 million coffee seedlings, were analyzed. Meloidogyne spp. was identified in 11 samples from four counties. Pratylenchus spp. and Rotylenchulus reniformis were detected in 281 and 47 samples, respectively. According to the Regulatory Instruction N° 35 from the Ministry of Agriculture, Livestock and Food Supply (MAPA), in Brazil, coffee seedlings infected by Meloidogyne spp. are prohibited for commercialization and/or planting. However, such restrictions do not apply to other PPN. Therefore, seedlings sold in Minas Gerais may constitute sources of dissemination for root-lesion nematodes (Pratylenchus spp.) and the reniform nematode (R. reniformis).

Investigating Absolute Stereochemical Configuration with Coulomb Explosion Imaging
Authors: Pitzer Martin , Berger Robert , Stohner Jürgen , Dörner Reinhard , Schöffler Markus
Published: June 2018

It is a particularly challenging task in stereochemistry to determine the absolute configuration of chiral molecules, i.e. to assign to a given sample the microscopic enantiomeric structure. In recent years, Coulomb Explosion Imaging (CEI) has been shown to yield directly the
absolute configuration of small molecules in the gas phase. This contribution describes the experimental basics of this approach, highlights the most significant results and discusses limitations. A short discussion on extending Coulomb Explosion Imaging beyond analytic aspects to fundamental questions of molecular chirality concludes this review.
Enantiospecific Adsorption and Decomposition of D- and L-Asp Mixtures on Cu(643)R&S
Authors: Dutta Soham , Gellman Andrew J.
Published: June 2018

The study of molecular chirality is essential to understanding the fundamentals of enantiospecific chemical interactions that are ubiquitous in the biochemistry of life on Earth. At a molecular level, there is insufficient understanding of chiral recognition and enantiomer–enantiomer
interaction (aggregation) of chiral molecules adsorbed on surfaces. Here, using enantiospecific isotopic labelling and surface sensitive techniques, we show that when the two enantiomers of chiral aspartic acid (Asp) are adsorbed on the naturally chiral Cu(643)R&S surfaces,
they decompose enantiospecifically depending on the chirality of the surface. The non-linear kinetics of the surface decomposition mechanism amplifies the difference between the decomposition rate constants of the two adsorbed enantiomers resulting in highly enantiospecific decomposition rates.
Further, we also demonstrate that Asp enantiomers aggregate homochirally on several chiral and achiral surfaces, amplifying the enantiomeric excess on the surface with respect to that in the gas phase, |ees |>|eeg. Our results show that it is possible to discern
the enantiospecific behavior of a complex adsorbate such as Asp and shed light on molecular level enantiospecific interactions on surfaces. The enantiospecific isotope labelling methods discussed in this paper allow probing of both the qualitative features of the Asp decomposition mechanism
on Cu(643)R&S and quantitative aspects of the adsorption equilibria of enantiomer mixtures.

Molecular analysis of human Ero1 reveals novel regulatory mechanisms for oxidative protein folding
Authors: Moilanen Antti , Korhonen Kati , Saaranen Mirva J , Ruddock Lloyd W
Published: June 2018

Oxidative protein folding in the ER is driven mainly by oxidases of the endoplasmic reticulum oxidoreductin 1 (Ero1) family. Their action is regulated to avoid cell stress, including hyperoxidation. Previously published regulatory mechanisms are based on the rearrangement of active site and regulatory disulfides. In this study, we identify two novel regulatory mechanisms. First, both human Ero1 isoforms exist in a dynamic mixed disulfide complex with protein disulfide isomerase, which involves cysteines (Cys166 in Ero1α and Cys165 in Ero1β) that have previously been regarded as being nonfunctional. Second, our kinetic studies reveal that Ero1 not only has a high affinity for molecular oxygen as the terminal acceptor of electrons but also that there is a high cooperativity of binding (Hill coefficient >3). This allows Ero1 to maintain high activity under hypoxic conditions, without compromising cellular viability under hyper-hypoxic conditions. These data, together with novel mechanistic details of differences in activation between the two human Ero1 isoforms, provide important new insights into the catalytic cycle of human Ero1 and how they have been fine-tuned to operate at low oxygen concentrations.

Published: June 2018

This article is dedicated to the problem of finding new teaching methods and activities for a student. Nowadays this issue is topical because traditional lectures, practices, and seminars need refreshing by implementing the innovative technology. The seminar is defined as a kind of practical class at university which implies independent research work. Students fulfill given tasks visually representing the material in the form of a summary, report, message, etc. The author’s idea comes from an item that teacher should take in consideration two vectors of skill development in the process of seminar modeling. They are specific skills in the special-topic sphere (math skills, etc.) and general independent researchers’ skills. The aim of our research is to create a procedure of conducting a modern seminar based on the platform Moodle. Moodle has been chosen as an open-source learning platform for MOOCs (Massive Open Online Courses) with a significantly enormous potential. The element named ‘Workshop’ can be created on this platform by setting some parameters by teachers. The most important thing is that an author takes into consideration a teacher’s goals and gives an efficient algorithm to adjust necessary parameters to particular goals. This procedure includes 4 phases, such as a setup phase, submission phase, assessment phase and grading evaluation. The main part of this article contains a lot of tips how to provide every phase with instructions, forms, criteria. The author doesn’t deal with using of other active Moodle-elements which ones are planned to be researched later.
