MICROBIAL FUEL CELL (MFC) IN TREATING SPENT CAUSTIC WASTEWATER
Authors: Fazli Norsafiah , Ahmad Mutamim Noor Sabrina , Ali Mohd Faizal
Published: October 2020

Some of the major problems encountered by the world are water pollution and natural resources depletion. One of the major factors which contribute to water pollution is insufficiently treated wastewater whereas the depletion of natural resources is due to the dependability of the fossil fuel as the main energy source. Both of these issues show the world urgently required an effective technology of wastewater treatment and energyrecovery. Microbial Fuel Cell (MFC) is a treatment method that can achieve the needs of effective treatment of wastewater and energy recovery simultaneously. As mentioned, insufficiently treated wastewater is one of the main causes which contributes to water pollution. Spent caustic wastewater is one of the industrial wastewater that is difficult to be treated, handled and disposed due to its noxious properties. Existing treatment method of treating spent caustic wastewater are limited by low efficiency. However, by applying MFCs, organic and inorganic contaminants are oxidized by biomass and produce electron that is transferred to electrode. The movement of the electron from anode to cathode generate electricity and turns MFC into a treatment method that able to provide both wastewater treatment and energy production. This article presents a review of spent caustic wastewater and its existing treatment method as well as the MFC researches in terms of its configuration and factors affecting its performance

Published: October 2020

Microwave-assisted hydrodistillatlion (MAH) extraction process can extract phytosterol (beta-sitosterol) from Leucaena leucochepala. The suitable parameter of the extraction process to extract the highest yield of phytosterol srom a plant can be optimized by using central composit design (CCCD). Two parameters extraction process were studied which are duration of time (4 to 8 minutes) and solvent ethanol concentration (55%-95%) to gain the highest yield of extracted beta-sitosterol from Leucaena leucochepala. The Liebermann-Burchard analysis was used to analyse phytosterol content in the extracted from the samples. The CCD model parameter was significant because of the values for Prob>F is less tahn 0.0500 which are 0.006 and value lack of fit F-value which is 5.44 represent only 6.77% chances to occur failure. This indicated the CCD with duration of extraction and the ethanol solvent concentration is the optimum parameter for the extraction of beta-sitosterol (phytosterol) from Leucaena leucochepala legume pod with the highest yield of phytosterol of 0.2717 mg/mL at 75% ethanol and 6 minutes.

Published: October 2020

Cellulose nanocrystal (CNC) was extracted from filter paper and isolated via sulphuric acid hydrolysis. This CNC was used as reinforcing elements in natural rubber latex (NRL) along with the cross-linking agents to prepare nanocomposite films. The effect of CNC loading on the mechanical properties, functional group presence and the glass transition temperature (Tg) of CNC/NRL nanocomposite at curing temperature of 70°C and 80°C were studied, respectively. CNC size and dimension was characterized using transmission electron microscope (TEM). Significant improvement of Young’s modulus was observed as a result of the addition of CNC loading at 3 wt.% and the Tg only showed a small increase upon the addition of CNC. The best nanocomposite was found at a curing temperature of 80°C with a tensile strength of 144% improvement.
A RECOMMENDATION AND CONSUMER PREFERENCES FOR ADVERTISING MEDIA OF A RETAIL COMPANY PROMO PRODUCT ON A RIDER’S JACKET OF A RIDESHARING COMPANY USING CHOICE-BASED CONJOINT
Authors: Arfan Ridho , Qurtubi Qurtubi
Published: October 2020

Consumer preference analysis is needed to know the advertising media that have a big influence on consumers in making decisions to buy a product, the advertising media applied to rider’s jackets of a ridesharing company. Ride sharing services is a flexible type of advertising media. Flexible advertising media requires a product with fast turnover. Retail products are dominated by primary products with fast turnover. The Company’s rider jacket has a position variable with three levels; bottom, top and separated. Mostly retail products are food, beverage, personal, and household needs. The retail products displayed on the jacket can be 1-2 product(s), 3-6 products, and more than 6 products. Using these attributes and levels, the objective of this study is to get the best design or the best level combination for advertising media of retail promo product on a ridesharing rider's jacket by consumer preferences. To get the best combination of consumer preferences, Choice Based Conjoint method is used with the amount of 106 data. The data obtained is the preference of 106 respondents who once had experience of using the taxibike feature from the ridesharing application. The results of this analysis show the best level of position attribute is the bottom position, the best level of product type attribute is the type of product mixed or alternating and the best number of products to be plotted are 1-2 products.

Published: October 2020

The port has a fairly dense loading/unloading activity according to the total flow of goods it manages. In addition to high work activities, environment factors such as noise and work climate can also affect the occurrence of work fatigue.  Therefore, this study aims to determine factors associated with work fatigue in loading/unloading workers at the port.  This study uses cross sectional study design with simple random sampling.  Data analysis used the Paired Sample T-Test and Chi-Square test.  The results showed that there was a difference of fatigue before and after work and as many as 71.2% of workers experienced moderate fatigue.  It is known that age (p-value = 0,000), breakfast habits (p-value = 0,000), and years of service (p-value = 0,000) have a significant correlation with work fatigue, while nutritional status (p-value = 0.203), workload (p-value = 0.140), hot work climate (p-value = 0.362), and noise (p-value = 0.880) have no correlation with work fatigue.  It was concluded that age, breakfast habits and work duration were related to work fatigue in loading/unloading labor.  Therefore, workers are advised to be used to have breakfast with the right menu and time and workers should wear hats while working to reduce sun exposure.

Published: October 2020

Female Sex Workers (FSW) are a group of populations at high risk of transmitting HIV/AIDS. In Indonesia, it is predicted that more than 50% of FSW suffer from sexually transmitted diseases (STDs), as well as in the district of Batang, Central Java, the most cases of HIV/AIDS in FSW. The main causes are weak sexual negotiation skills and economic reasons. The model of behavior change is the main key in decreasing cases of HIV/AIDS transmission. The Care Support Education (CSE) model is an innovative community-based behavior change communication. This research is pre experimental research with one group pretest posttest design. The population is FSW in Batang district localization totaling 123 people. Samples were taken by purposive sampling of 57 people. Test the effect of applying the CSE model on behavior change was analyzed using the Mc Nemar test. Condom use in risky sexual behavior among FSWs was still low (15.8%). Factors that influence it are knowledge, attitudes, perceptions of vulnerability, seriousness, benefits, negotiation capabilities and customer support. The application of the CSE model can significantly increase knowledge (p value 0.00006), attitude (0.0001), condom negotiation skills (0.000001) and practise of using condoms (0.000005).

La historia jamás contada de Blancanieves
Authors: Cañas Pelayo Marcos Rafael
Published: October 2020

Blancanieves ha sido un icono cultural desde que los hermanos Grimm escribieron su historia en 1812, basándose en el cuento popular de la hermosa princesa. A pesar de la gran variedad de versiones cinematográficas, desde el clásico animado de Disney hasta la reciente reinvención del cuento de hadas por Universal Pictures, nunca antes hasta la llegada del proyecto del director español Pablo Berger se le había adaptado con un sentido de metáfora ecléctica más allá de los siglos y nacionalidades. Blancanieves (2012) emerge como un melodrama situado en el sur de España durante la década de los veinte del siglo pasado, con una heroína inusual convertida en torera, para la gran pantalla con los Enanitos. El propósito de nuestro artículo es analizar tanto la película como sus personajes con el fin de discernir las circunstancias culturales, sociales y folclóricas que actúan en ella para configurar una Blancanieves independiente, aunque todavía con conexiones con sus versiones predecesoras. En términos metodológicos, el propósito fue estudiar las muchas referencias manejadas en el trabajo de Pablo Berger desde distintos prismas: no solo desde el análisis fílmico ¾por ejemplo, las estructuras narrativas evidencian una deuda con el cine mudo alemán y francés¾, sino también por medio de diversos textos históricos y literarios.
El cambio de la imagen de Dios en la Edad Media.
Authors: Aznar-Sala Javier
Published: October 2020

La Edad Media se caracterizó por la relación entre la filosofía clásica y el saber teológico. Desde esta perspectiva, donde brilló de forma singular el teólogo Santo Tomás de Aquino, los frutos en el quehacer filosófico fueron innumerables. La imagen de Dios se nutría de múltiples semejanzas que en el uno de los seres podían ayudar a una mejor comprensión de la realidad trinitaria divina. El mundo servía como plataforma analógica para acercarse al misterio más íntimo de Dios en la denominada “metafísica del Ser”. No obstante, esta confianza en el método racional se vuelve en una enorme desconfianza que vendrá en con el nominalismo de Guillermo de Ockham, desde donde se acentúa un fideísmo extremo y una clara desconfianza ante la razón. Esta postura se exagera todavía más con Lutero y la idea de Dios se trona fría y alejada de cualquier pretensión racional. Como correlación lógica a todo esto van apareciendo ideas naturalistas de lo divino que se van sucediendo desde el deísmo al panteísmo. Toda esta realidad ha llegado hasta nuestros días y es necesario comprenderla para, a su vez, comprender la secularización del presente.

Published: October 2020

El presente artículo nos permite ver un acercamiento a la realidad juvenil desde la Teología Fundamental Contextual, en tanto que contiene unas reflexiones acerca de los imaginarios de los jóvenes (sobre Dios, la religión, la Iglesia, la fe, el creyente), su actitud ante la religión (creencia, increencia, indiferencia, sincretismo), sus creencias religiosas, sus actitudes frente a la religión, sus prácticas religiosas, la forma como responden a las nuevas propuestas religiosas (de dentro y de fuera de su comunidad religiosa), las diversas modalidades de pertenencia a las confesiones y los diversos grados de compromiso frente a su religión. Todo esto plantea importantes desafíos que la teología fundamental contextual en clave dialógica no puede ignorar.
Towards a Phonology of Scandinavian Latin Runic Inscriptions: A Corpus-Based Analysis
Authors: Tarsi Matteo
Published: October 2020

The present paper is a study of the rendering of Latin in Scandinavian runic inscriptions. The analysis focuses on a small corpus of thirteen inscriptions from the whole of Scandinavia and its periph- eral settlements. The investigated phenomena are: 1) Lat. /e/ in stressed and unstressed position; 2) Lat. /d/ and /t/ in initial, intervocalic and final position; 3) Lat. /t/ + /j/ /_V; 4) Lat. /b/, /p/ and /v/ in initial and intervocalic position. From the analysis of the data it can be observed that the runic rendering of Latin can either adhere to its written model or mirror the actual pronunciation of Medieval Latin in Scandinavia.
Observaciones sobre la sintaxis de la toponimia en el itinerario del Pseudo Antonino de Placentia
Authors: Abellán Carmen Arias
Published: October 2020

One of the basic features of the itineraries is the presence of toponyms. In the particular case of the Christian itineraries, toponyms operate in two different levels: in the places of the biblical past that is meant to be recalled in the peregrination itself and in the places “truly” visited. This fact gives toponyms a very interesting “diversity”, not only from a cultural standpoint, but also because of all kinds of linguistic facts: phonetic, morphologic, syntactic, etc. These linguistic facts reflect the situation and evolution of late Latin, an aspect of which I am going to focus on the syntactic level.
Aspetti della Subordinazione a verbo non finito nella Vulgata1
Authors: Greco Paolo , Ferrari Valentina
Published: October 2020

This paper aims at describing some of the main structural and functional characteristics of two subordinate patterns, namely infinitive clauses governed by verba dicendi et sentiendi (i.e. the so-called Accusativus cum Infinitivo) and participial clauses, as they occur in the Vulgate. The characteristics of the use of the Accusativus cum Infinitivo will be interpreted within the context of the uses of this structure in other Latin texts written in different periods. In particular, and in the framework of a functional-typologi- cal approach, we will investigate word-order phenomena.
Aspetti della subordinazione completiva nel De consolatione philosophiae di Boezio*
Authors: Ferrari Valentina
Published: October 2020

This paper aims at describing some of the main structural and functional characteristics of completive clauses governed by verba dicendi et sentiendi in Boethius's De consolatione philosophiae. The characteristics of the use of the Accusativus cum Infinitivo (AcI) will be analysed in comparison with the uses of other Latin authors. The data will be described on the basis of two main aspects: constituent order, and the coreferentiality of the subject of the AcI with elements in the main clause. Compared to the predominance of AcI constructions, quod-clauses show a consistent pattern and are limited to well- defined contexts. Some aspects of the use of quin and ut will also be described. Special attention will be given to the problems of syntactic and semantic interpretation of the governing verbs, which can be difficult to define clearly. This study will also set the ground for further research on the influence of Boethius's Latin model on Italo-Romance literary texts in the Middle Ages, both on the syntactic and the stilistic level.
Cultic Verbs in Vetus Latina Daniel and in Jerome’s Translations of the Greek Additions to Daniel1
Authors: Zilverberg Kevin
Published: October 2020

The Vetus Latina Bible includes a variety of vocabulary according to various translators’ and revisers’ milieus and intents as they worked from Greek originals. This study aims to analyze the use of cultic verbs in the Vetus Latina Book of Daniel in all its pluriformity, and in Jerome’s translations of the Greek additions to this book.

In order to do so, I focus on key patristic witnesses to trace verbs denoting or connoting divine worship, from the time of Tertullian of Carthage, over Cyprian of Carthage and Lucifer of Caralis, to Jerome of Stridon. The expressions treated, each corresponding to a Greek verb, are: seruio, colo, famulor, appareo, exomologesin facio, hymnum cano, sacrifico, timeo, benedico, adoro, laudo, confiteor, and primitiae. They are analyzed in relation to their Greek Vorlagen and to the Latin context consisting in similar renderings by the same Fathers. The biblical book’s fragmentary VL manuscript evidence and the wider patristic and liturgical tradition are also taken into account. This approach allows for a diachronic view marked sometimes by continuity, sometimes by change, for the Latin rendering of a Greek verb.
La transition latino-romane : problèmes de la reconstruction
Authors: Kiss Sándor
Published: October 2020

Proto-Romance linguistic transformations are partially hidden by the archaic style that char- acterizes Late Latin documents. However, these texts (e. g. chronicles) permit insights into the changes undergone by the oral language, because authors and scribes can reproduce unconsciously their own speech habits, already different from Classical standard. In our presentation, this curious duality is shown by the example of noun declension, which is undermined, but not yet completely eliminated, in 7th century Latin. A comparison is made between the so-called Fredegarius, a Merovingian chronicle, and an early French poem, the Eulalia Sequence, which manifests the last stage of the declension, just before its disappearance. The morphological change has its counterpart in the restructuration of the sentence: the neighbourhood of subject and verb becomes usual in the surface structure, and certain limitations are im- posed upon the freedom of word order. Thus, the reconstruction process we propose has two aspects: it is necessary to describe the diastratic variation at different moments of the history of Late Latin, and, on the other hand, the results need to be compared with the Early Romance linguistic systems. In this manner, reconstruction can show the coexistence of tradition and innovation in the language, a necessary condition of its normal functioning.
Une théorie résurgente : l’africitas
Authors: Callebat Louis
Published: October 2020

The africitas theory, for which Einar Löfstedt wrote in 1959 that: “it constituted only merely a historical significance”, nevertheless enjoys currently a militant resurgence, in particular clarified from a rereading of Apuleius.

Our communication aims to achieve two objectives: 1) To attempt, with the insight of over a century, an update, taking into account the scientific, historical, linguistic achievement involved in the establishment of this theory: nature of the corpus; research methods; regional diversification of Latin; linguistic state of roman Africa; sermo cotidianus and cultural languages; ideological presuppositions. 2) To evaluate the theoretical and methodological relevance of the theses supported by the contemporary supporters of a revivified africitas.
Costruzioni ipotetiche parentetiche usate come marcatori di cortesia in latino tardo: il tipo si placet, si videtur, si molestum non est *
Authors: Fedriani Chiara
Published: October 2020

This paper looks at uses and pragmatic functions of five hypothetic clauses used parenthetically in Late Latin to soften the illocutionary force of potentially face-threatening acts such as orders and requests. Specifically, the data show that these politeness markers typically mitigate a very specific type of interactional move, i.e., meta-textual proposals with topic-management, turn-yielding, and discourseorganizational concerns. Moreover, the corpus-based study has revealed that they are found above all in Augustine’s philosophical dialogues. Evidence from earlier research has shown, on the other hand, that in Classical Latin si placet was used almost exclusively in Cicero’s philosophical dialogues: this suggests a process of imitation within a very specific discourse tradition, where these markers are perceived as a stylistic feature typical of urbane conversations among educated friends.
Evidentiality and Mirativity in the Language of Roman Comedy
Authors: Zheltova Elena V.
Published: October 2020

The paper deals with the ways of expressing evidential and mirative semantics in the language of Roman comedy. The author claims that the phenomena under consideration belong to the grammar rather than to the lexicon of the Latin language, and shows that various evidential and mirative values can be expressed by the use of verbal tenses, voices, moods and syntactic construction. It is stressed that evidential and mirative functions in such units result only from the interaction of different linguistic parameters within a certain context and does not reside in the units taken in isolation. The main focus of the study is on the linguistic techniques which were preferred by Plautus and Terence. The comparative analysis of the linguistic strategies found in the author's present and the previous research demonstrates that the choice of a particular strategy depends on a given genre. Thus, some strategies (e.g., impersonal passive, inferential perfect and future, imperfect of a truth just recognized, mirative use of the subjunctive and infinitive) are preferred by comic poets while other techniques (e.g., deductive use of debere, gnomic future as a reportative strategy, cum inversum as a mirative device) which may be used in historic or epic narrative, never occur in the language of Roman comedy.
Traits de langue tardive et/ou vulgaire dans la poésie d'Ausone
Authors: Wolff Étienne
Published: October 2020

Ausonius' poetry is marked by a great deal of formal research, which takes five main aspects: metrical virtuosity, Latin-Greek bilingualism, centon, games on words, lexical elaboration. It is this last point that will hold our attention here. If the language of Ausonius is generally consistent with the classi- cal standards from the point of view of the syntax, it is not exactly the same for the lexicon. Ausonius sometimes uses late words and/or is influenced by the vulgar language. This characteristic of his language has been little studied and we must often resort to the old thesis of A. Delachaux. In this paper, we will review these late and/or vulgar words, to try to draw up a typology. We will then examine the sty- listic use that Ausonius makes of them, because, as a refined poet, he never chooses his words randomly. We will finally see if it is possible to infer some more general conclusions about the linguistic situation in Aquitania in the fourth century.
Latinité d’occident, latinité d’orient: Le ‘latin’ du Livre des cérémonies de Constantin Porphyrogénète
Authors: Biville Frédérique
Published: October 2020

After the fall of the Western Roman Empire, the imperial ritual was preserved and systematized in the East, in the ‘Byzantine’ Empire, by intensifying and Christianizing. The Book of Ceremonies by Constantine Porphyrogennetos, written in Greek in Constantinople in the 10th century, by compiling protocols of the previous centuries, gathers a rich collection of court rituals to be observed during the great religious and civil ceremonies which accompanied the important events of the reigns of the sovereigns, and the sportive events at the Hippodrome. We investigate about the permanence and the future of the Latin language in the ceremonial of the Byzantine Court: the survival of formulaic expressions of order and acclamation in Latin (rhômaïzein), Latin phrases underlaying the Greek text, and a great lot of Latinisms (rhômaï(k)a lexis) in the institutional and technical lexicon, sometimes unknown in Latin, which attest integrational processes, lexical creation, and phenomens of ‘aller-retour’ (round trip) between the West and the East, and between the Greek and the Latin languages.
Thèmes et variations Réflexions stylistiques sur l’itinéraire d’Égérie
Authors: Horváthy Sára
Published: October 2020

Egeria, a 4th century pious woman from the south of present-day Spain, retold, after visiting Palestine with the Bible in hand, her observations to her sisters. If the linguistic aspects of her letters are quite well-known, much less is known about its stylistic value, inappropriately called “simple”.

What seems to be boringly the same again and again, is in fact a constantly renewed and perfectly mastered “variation on a theme”, just as in a well-composed piece of music. Her apparent objectivity is indeed a wish to focus on what she considers the most important, namely to tell her community, as closely to reality as possible, what she observed during her pilgrimage. However, Egeria’s latin is also a testimony of the christian lexicon in construction and of the social changes that were in progress by that time.

Linguistics and stylistics work together here, the choice of a word or a grammatical formula reveals hidden information about the proper style of an author who, despite her supposed objectivity, had real personal purposes.

Resumo Introdução A interface implante-pilar protético e a formação dos seus microgaps são aspectos relevantes na transferência das cargas e na resposta biológica, estando ligadas ao sucesso da reabilitação. Objetivo Avaliar microgaps na interface entre a conexão interna do implante do tipo Cone Morse e a superfície do componente protético por meio da microscopia eletrônica de varredura (MEV). Material e método Foram utilizados 20 implantes dentários de tamanho 3,75 × 11,0mm do tipo Cone Morse com seus respectivos pilares protéticos da Singular® (Singular Implants, RN, Brasil). Os munhões retos foram acoplados aos implantes com torque de 32N/cm2 e o conjunto resultante foi emergido em base de Resina Epóxi ES260, para permitir secção longitudinal da amostra. As amostras foram analisadas e os microgaps mensurados no MEV (JEOL JCM-5700, MA, USA), e posteriormente os dados foram analisados. Resultado A média e o desvio padrão dos maiores microgaps foram observados na parte apical do implante nos lados direito e esquerdo, sendo 1,44±2,68 e 1,16±1,49 μm, respectivamente. Os menores microgaps foram na parte superior do implante nos lados direito e esquerdo, sendo 0,60±0,73 e 0,66±0,67 μm, respectivamente. Contudo, no teste de Kruskal-Wallis, não houve diferença estatisticamente significativa entre as regiões dos implantes, tanto para o lado esquerdo (p=0,692) como para o direito (p=0,865). No teste de Mann-Whitney, não houve diferenças estatisticamente significativas entre os lados para as diferentes regiões dos implantes. Conclusão Mesmo com a presença de microgaps na interface implante-pilar protético, estes apresentam tamanho inferior ao que causaria problemas biológicos e mecânicos. As amostras analisadas quanto à sua compatibilidade de encaixe foram satisfatórias.

Published: October 2020

Abstract The aim of the present study was to perform the floristic survey of the wetlands of the Parque Estadual do Ibitipoca (PEIB), comparing them regarding richness, floristic composition and life forms, based on monthly expeditions to collect vascular plants. Eighty-one (81) species were found in the moist grassland, most of them being endemic to Brazil and included in 55 genera and 21 families. The most representative families were Asteraceae (22 spp.), Melastomataceae (nine spp.), Xyridaceae (seven spp.), Poaceae and Orchidaceae (six spp. each), totalizing 62% of the sampled species. Twenty-seven (27) species were found in the seasonal pond, distributed in 23 genera and 11 families. Families with the highest specific richness were Poaceae (eight spp.), Cyperaceae and Asteraceae (five spp. each), totalizing 67% of the sampled species. There was a predominance of hemicryptophyte life form (nearly 43% of the moist grasslands and 63% of the seasonal pond) in both areas. The floristic analysis results showed great importance to conservation with 22% of species under some threatened category, 12 species endemics to Minas Gerais state and one new species of Cyperaceae. Furthermore, only five species occur in both wetland types (5.1% of the species richness).

Published: October 2020

Abstract The objective was to describe and characterize the fruit morphology, seeds, seedlings and germination of Richeria grandis. Mature fruits were collected from matrix trees located in gallery forests. After, morphological descriptions were performed. Biometric measurement of fruits and seeds were carried out. A total of 650 seeds were randomly separated, with 20% being used for germination and humidity testing on the same day of collection and the others stored for 5, 10, 15 and 20 days. The germination test was performed in a gerbox, conducted in a laboratory chamber of the type B.O.D (biochemical oxygen demand) with a photoperiod of 12h and a temperature of 25 ºC ± 1 ºC. Periodic observations were made to monitor the development of the seedlings until the first germinated seeds reached the full seedling stage. The fruit of R. grandis is a simple, dry, capsule type septifraga, dehiscent and schizocarpic, with average length of 16.24 mm and an average width of 8.57 mm. The seed is an ellipsoid shape, containing a sarcotesta and has an average length of 7.40 mm and an average width of 4.57 mm. R. grandis presents recalcitrant seeds, which emerge in a Phanero-epigene-foliaceous manner. The radicle breaks the integument on the second day after sowing, the collection is evidenced on the 10th day, separating the primary root from the hypocotyl. At day 16, the cotyledons expand from the forehead, positioned at a 90º angle to the hypocotyl. The protophyll and the epicotyl appear only after the 50th day, characterizing the complete seedling.

Authors: Silveira Julio Gonçalves da , Sousa Mayara Cynthia , Leder Solange Maria
Published: October 2020

Resumo Uma parcela considerável das pesquisas sobre o conforto térmico não considera a dinâmica da relação entre os usuários e a edificação, bem como há poucos estudos sobre conforto térmico e o idoso, especialmente em clima tropical. Esta pesquisa abordou a sensação e a percepção térmica em conjunto habitacional com as estratégias de adaptação ao ambiente, tendo como população indivíduos acima de 60 anos. Para isso, foram coletados dados mediante entrevistas semiestruturadas com 90 residentes de três conjuntos habitacionais para idosos, de caráter social e mesmo projeto arquitetônico, localizados nas cidades paraibanas de João Pessoa, Campina Grande e Cajazeiras. Os dados foram analisados por meio de técnicas estatísticas descritivas e inferenciais. Os idosos apresentaram tendência a preferir condições térmicas mais amenas àquelas vivenciadas por eles na habitação em análise. A ventilação natural é considerada uma variável importante para o conforto térmico, contudo os entrevistados relatam fechar as esquadrias para evitar a entrada de insetos e animais, dificultando a ventilação natural. Também foi identificado que fatores culturais e a necessidade de segurança interferem no fechamento das aberturas. Não foram encontradas correlações significativas entre o sexo dos entrevistados e suas respostas.

Resumo O crescimento da indústria da construção civil é de grande importância para a manutenção e sustentação da economia brasileira, mas essa indústria utiliza grande quantidade de recursos naturais e consequentemente gera grandes volumes de resíduos de construção civil (RCC). Esforços na minimização de RCC geralmente estão direcionados aos estágios de construção das obras, mas não ao estágio de projetos. Assim, a tecnologia BIM surge como uma importante ferramenta ao possibilitar uma melhor análise e controle da geração de resíduos. Este trabalho propõe um modelo BIM para estimar o RCC e o custo de retirada na fase de projeto, pois nela ainda são inexistentes ações visando estimar o resíduo a ser gerado em uma obra. Para isso, utilizaram-se etapas como a revisão sistemática da literatura, levantamento de índices de perdas e modelagem BIM. Os resultados obtidos revelaram que 10% dos RCC quantificados pertencem à classe B, e 90%, à classe A, sendo a argamassa o material com o maior potencial de desperdício, 56% da estimativa total. A modelagem através de dados estatísticos e indicadores pode contribuir na elaboração do plano de gerenciamento de resíduos de construção civil (PGRCC), aperfeiçoando, dessa forma, o planejamento, com redução do RCC.
Production of agroindustrial ashes with pozzolanic activity via acid leaching, conjugated burning and ultrafine grinding

Published: October 2020

Abstract This paper aims to study the production and the physical and chemical characterization of rice husk, sugarcane bagasse, corn straw, and bamboo leaf ashes to use as pozzolans. The ash production steps basically consisted of raw material collection, chemical treatment by citric acid leaching, conjugated burning (thermal processing) and ultrafine grinding (mechanical processing) of the produced ashes. The results indicated that all ashes could be classified as pozzolanic additions based on specific standards. The high pozzolanicity of the ashes was confirmed by testing the electrical conductivity, mechanical performance index, and hydration kinetics of cement pastes by isothermal calorimetry. Therefore, the production processes used in this work were effective in producing highly reactive pozzolanic materials.
Influência das frações granulométricas de agregados miúdos reciclados no comportamento de argamassas de cimento
Authors: Correa Cássia Rabelo , Pereira Cláudio Henrique , Rêgo João Henrique Silva
Published: October 2020

Resumo O trabalho parte do pressuposto de que as frações granulométricas dos agregados miúdos reciclados apresentam características diferentes, as quais influenciariam de forma distinta no comportamento mecânico das argamassas. Nesse sentido, o artigo propõe o estudo das frações granulométricas de duas areias recicladas: areia de resíduo de construção e demolição (AR1) e areia de resíduo de concreto (AR2). As areias recicladas foram submetidas a ensaios de caracterização física e FRX, e na sequência foram incorporadas em argamassas. Os resultados revelaram que as areias recicladas são formadas por dois grupos com características e tendências distintas: (1) o grupo das “frações grossas”, formado pelas frações grossa e média-grossa; e (2) o grupo das “frações finas”, formado pelas frações média-fina e fina. O estudo mostrou que a diversidade dos materiais de origem da AR1 fez com que a pasta de cimento se diluísse em suas frações; ao contrário, com a AR2, a pasta se concentrou, principalmente nas “frações finas”. Sendo assim, as “frações finas” da AR1 se mostraram semelhantes à areia do IPT (utilizada como referência) e mais adequadas do que as “frações finas” da AR2. O estudo concluiu que existem diferenças nos comportamentos mecânicos das argamassas conforme a fração granulométrica é substituída, o que amplia as possibilidades de aplicação de agregados miúdos reciclados em designs de misturas cimentícias.

Authors: Ribeiro Eduardo Augusto , Correa Laura
Published: October 2020

Nos últimos anos, o município de Massaranduba-SC vem sendo destaque no cultivo de peixes de água doce. Em 2018, o Centro de Desenvolvimento em Aquicultura e Pesca (Cedap) demonstrou que a atividade produziu cerca de 1,781 toneladas de peixes na modalidade comercial. No entanto, o piscicultor enfrenta desafios típicos do setor como a da assistência técnica, recursos financeiros e atualmente o fator clima e seus impactos no meio ambiente começa a ser contabilizado no processo produtivo. O presente trabalho objetiva caracterizar o perfil do piscicultor no município de Massaranduba, com ênfase em sua percepção climática acerca do cenário da piscicultura. Esta pesquisa contou com duas atividades; na primeira, foram aplicados questionários em 14 (quatorze) piscicultores cadastrados no banco de dados da Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri). A segunda atividade foi uma capacitação intitulada “Panorama Atual das Condições Climáticas”, com a presença dos entrevistados e aberto para a comunidade interessada. Os principais resultados da investigação foi a construção do perfil socioeconômico dos piscicultores e análise da percepção dos mesmos sobre o clima. O perfil é de predominância do sexo masculino, adulto, com um núcleo familiar formado (em média) por 3 membros. O nível escolar constatado foi de primeiro grau completo e com formação técnica na área. A capacitação discutiu os resultados da pesquisa com os entrevistados e conscientizou o público sobre as questões climáticas e impactos ambientais neste setor. Diante disso, foi possível analisar um conjunto de situações que fortalecem a importância desse diagnóstico para se pensar futuras estratégias de capacitação e extensão tecnológica dos envolvidos na piscicultura do município.
Comparison of the Levonorgestrel-releasing intrauterine system and oral tranexamic acid in the treatment of dysfunctional uterine bleeding
Authors: ERDOĞDU Emre , SUER Necdet
Published: October 2020

Materials and Method: 60 patients who were diagnosed with DUB and were treated with either oral tranexamic acid 3gr/day or LNG-IUS were included in the study. Bleeding scores(PBAS), duration of bleeding and haemoglobin values before the therapy were recorded. Patients were evaluated again for the same parameters and possible side effects on the 3rd and 6th months of therapy. Results: Decrease in duration of bleeding on the 3rd and 6th months of therapy were statistically significant in both groups(p<0,05). While there was no statistically significant difference on the decrease in the duration of bleeding on the 3rd month of therapy(p>0,05), the decrease was more significant in the LNG-IUS group than the tranexamic acid group on the 6th month(p<0,05). In the tranexamic acid group, PBAS dropped by 55 % on the 3rd month, and 62% on the 6th month, but these changes were not significantly different from each other(p>0,05). In the LNG-IUS group, PBAS decreased by 87.5 % on the 3rd month, and 90.5% on the 6th month, and these changes were statistically significant(p<0,05). However, the decrease in the amount of bleeding was significantly more in the LNG-IUS group than the tranexamic acid group(p<0,05). While haemoglobin levels increased 5.6% on the 3rd month and 9.4% on the 6th month in the LNG-IUS group, they increased 3.6% on the 3rd month and 4.5% on the 6th month in the tranexamic acid group. In the LNG-IUS group the most common complaint was mastalgia on the 3rd month of therapy(40%, 10 patients), and oligomenorrhea-amenorrhea on the 6th month (43%, 10 patients). After 6 months, 78% of patients continued the treatment, while 2 patients(6.6%) quit the therapy because of the side effects. In the tranexamic acid group, the compliance rate was 63%, and none of the patients had discontinued the therapy due to side effects. Conclusion: Even though LNG-IUD is more effective than tranexamic acid in reducing blood loss in DUB patients, the major change in the menstrual cycle pattern and systemic side effects are the most common reasons for discontinuing therapy. Tranexamic acid reduces blood loss while conserving cycle patterns and fertility, and is better tolerated.
