Published: August 2017

Climate change is any substantial change in Earthâ€™s climate that lasts for an extended period oftime. Global warming refers to climate change that causes an increase in the average temperature of thelower atmosphere. Global warming is the combined result of anthropogenic (human-caused) emissionsof greenhouse gases and changes in solar irradiance, while climate change refers to any change in thestate of the climate that can be identified by changes in the average and/or the variability of its properties(e.g., temperature, precipitation), and that persists for an extended period, typically decades or longer.Green open space is one of solution for climate change mitigation.

Scaling Analysis and Its Implication for Asphaltene Deposition in a Wellbore
Authors: Davudov Davud , Moghanloo Rouzbeh Ghanbarnezhad , Flom Jonathan
Published: August 2017

The study presented here uses order-of-one—or o(1)—scaling analysis to identify dimensionless groups specific to asphaltene deposition along production tubing. The precipitation and subsequent deposition of asphaltene can lead to significant complications related to oilfield production. Aside from the many complications within a reservoir as well as surface equipment, the reduction in cross-sectional area caused by its deposition leads to increased pressure losses, reductions in volumetric flow capacity, and possible flow perturbations within a wellbore. Attempts to mitigate these adverse effects have focused on both hindering the precipitation of asphaltene and preventing its deposition after precipitated. The study used here attempts to quantify various hydrodynamic controls specific to asphaltene deposition.

With o(1) scaling analysis, four independent dimensionless groups were generated from momentum and mass-balance equations relating hydrodynamic effects to the rate of asphaltene deposition. The dimensionless group π4 was of particular interest because of its inherent relationship to the rate of deposition. This group was compared with both data and existing correlations taken from literature, and noticeable trends in the deposition rate with respect to average stream velocity were observed. One of the most important trends discerned by these comparisons was a clear distinction whereby the rate of asphaltene deposition, related through π4, decreases with increasing Reynolds numbers (Re) in lower ranges, but actually increases in higher ranges. Although the data did not cover the specific region of transition, various correlations suggest a clear cutoff between what was deemed a favorable regime, or Regime I, and a nonfavorable regime, or Regime II.

High temporal resolution rainfall rate estimation from rain gauge measurements
Authors: Song Yang , Han Dawei , Rico-Ramirez Miguel A.
Published: August 2017

Rainfall rates derived from tipping bucket rain gauges generally ignore the detailed variation at a finer temporal scale that particularly occurs in light rainfall events. This study extends the exploration of using artificial neural networks (ANNs), in comparison with the conventional linear interpolation method (LIM) and the cubic spline algorithm (CSA) for rainfall rate estimation at fine temporal resolution using rain gauge data based on a case study at Chilbolton and Sparsholt observatories, UK. A supervised feed-forward neural network integrated with the backpropagation algorithm is used to identify the complex nonlinear relationships between input and target variables. The results indicate that the ANN considerably outperforms the CSA and LIM with higher Nash–Sutcliffe efficiency, lower root mean square error and lower rainfall amount differences when compared to the disdrometer observations when the model is trained within a broad span of input values. Consistent stability in accurately estimating rainfall rate in different sites shows the intrinsic advantage of ANNs in learning and self-adaptive abilities in modelling complex nonlinear relationships between the inputs and target variables.
The importance of surface functional groups in the adsorption of copper onto walnut shell derived activated carbon
Authors: Xie Ruzhen , Jin Yan , Chen Yao , Jiang Wenju
Published: August 2017

In this study, activated carbon (AC) was prepared from walnut shell using chemical activation. The surface chemistry of the prepared AC was modified by introducing or blocking certain functional groups, and the role of the different functional groups involved in the copper uptake was investigated. The structural and chemical heterogeneity of the produced carbons are characterized by Fourier transform infrared spectrometry, X-ray photoelectron spectroscopy, Boehm titration method and N2/77 K adsorption isotherm analysis. The equilibrium and the kinetics of copper adsorption onto AC were studied. The results demonstrated that the functional groups on AC played an important role in copper uptake. Among various surface functional groups, the oxygen-containing group was found to play a critical role in the copper uptake, and oxidation is the most effective way to improve Cu (II) adsorption onto AC. Ion-exchange was identified to be the dominant mechanism in the copper uptake by AC. Some other types of interactions, like complexation, were also proven to be involved in the adsorption process, while physical force was found to play a small role in the copper uptake. The regeneration of copper-loaded AC and the recovery of copper were also studied to evaluate the reusability of the oxidized AC.
Continuous treatment of Acid Red B with activated sludge bioaugmented by a yeast Candida tropicalis TL-F1 and microbial community dynamics
Authors: Liu Jing , Song Li , Jiang Tingting , Jia Xuan , Tan Liang
Published: August 2017

Continuous treatment of Acid Red B (ARB) with activated sludge (AS) bioaugmented by an azo-degrading yeast Candida tropicalis TL-F1 under aerobic conditions was investigated in the form of sequencing batch tests. Dynamics of both bacterial and fungal communities were analyzed using polymerase chain reaction followed by denaturing gradient gel electrophoresis (PCR-DGGE) method. The results showed that bioaugmentation with the yeast TL-F1 improved the performance of AS for continuously decolorizing, degrading and detoxifying ARB. Meanwhile, the AS systems bioaugmented by the yeast TL-F1 showed higher sludge concentration and better AS settleability. The result of PCR-DGGE suggested that microbial communities of both bacteria and fungi shifted due to treatment of ARB and bioaugmentation. Some dominant bacteria and fungi were identified as probably efficient degraders of ARB or its decolorization byproducts. Furthermore, the yeast TL-F1 was found as one of the dominant fungi in all the three bioaugmented systems, suggesting that bioaugmentation was successful due to the colonization of the yeast TL-F1 in AS systems.

The condensation reaction to synthesize the dibenzylidenecyclohexanone 8b was performed by reacting benzaldehyde 4 and cyclohexanone 2 (mole ratio of 2:1) with NaOH as catalyst for 2 min under microwave irradiation. The benzaldehyde derivatives used in this study were 4-methoxybenzaldehyde and 3,4-dimethoxybenzaldehyde and gave of (2E,6E)-bis(4-methoxy benzylidene)cyclohexanone 8a and (2E,6E)-bis(3,4-dimethoxybenzylidene)cyclohexanone 8c, respectively. The study was commenced by searching the optimum concentration of NaOH. The reaction yield was determined by TLC scanner and the structure was elucidated by FTIR and NMR spectrometers. For the comparison, the reaction was also carried out by using stirring method. The results showed that optimum concentration of NaOH was 5 mmole. By using the optimum condition via MAOS method, the compounds 8a, 8b and 8c were obtained in 100, 98 and 93%, respectively. The research also proved that the method of dibenzylidenecyclohexanones (8) synthesis using MAOS was more efficient than stirring method.

The southern part of the Special Province of Yogyakarta consists of a coastline spanning over 113 km, under the administrations of Bantul, Gunung Kidul and Kulon Progo regencies, that can become an asset and resource of an important economy. Cabe Merah (red chilli) is one of the commodities that show high numbers of productivity in Kulon Progo Regency. Activities of red chilli farming on the coastal land of this regency have been growing, especially since the establishment of commodity auction market to help farmers sell their harvests. The study was conducted to (1) find out the size of production in red chilli agribusiness on coastal land, (2) to analyze the risk levels of production faced by the farmers, and (3) how to mitigate the production risks on coastal red chilli farming. There were 40 participating farmers from Banaran Village, Galur Sub-district, Kulon Progo Regency. The location was intentionally chosen by using  multistage area sampling method. The data used were collected from the production and income of three growing seasons. Data analyses were performed using production risk and The House of Risk methods. Based on the variance coefficient, the production risks level was at 0,03 with the production lower limit of 9.596 Kg/Ha, which showed a low level of risk. The various risk mitigation strategies have been performed by the farmers to lessen the risks that can causes losses in the process of coastal red chilli productions.

Evaluamos el efecto de cinco isotiocianatos (ITC) para controlar a Rhizoctonia solani Kühn AG-3, un hongo causante de enfermedades en plantas de importancia agrícola, como estudio preliminar para la implementación de la técnica de biofumigación en Colombia. Realizamos pruebas in vitro con diluciones de cinco ITC, con metanol como solvente, en cajas de Petri con medio PDA y calculamos las áreas de crecimiento micelial, el porcentaje de inhibición y la concentración efectiva media (CE50). La respuesta del patógeno fue dependiente de la concentración y del tipo de ITC aplicado. Todos los ITC en concentraciones al 10% presentaron efecto inhibitorio total. PEITC y BITC tuvieron un efecto fungistático hasta los seis y 27 días después de aplicados los tratamientos, respectivamente. PITC, AITC y MITC mantuvieron el efecto inhibitorio por más de un año después de aplicados los tratamientos. PITC fue más eficaz en controlar R. solani Kühn AG-3 que los otros ITC, mostrando el valor más bajo de la CE50 para la inhibición del crecimiento micelial.
Can one wade twice into the same Seine?
Authors: Assi Karttunen
Published: August 2017

In 2013, the Elysian Fields working group received a grant for two concerts based on the concept of a musician’s relationship to a specific city. The idea was to reveal the musician’s living relationship to history in the context of three European towns; Amsterdam, Paris and Helsinki.

I belonged to the group planning the Paris concert, and therefore my article deals with the musicians’ working process and the phases of the practising/rehearsing in preparation for this event, which was staged in January 2015. The Elysian ensemble comprised: Varpu Haavisto, viola da gamba; Essi Iso-Oja, harp; Assi Karttunen, harpsichord, Katja Vaahtera, soprano; and Hannu Vasara, violin.

During the artistic process, the chosen material is shaped, crystallized, constituted and transformed. All of these forms of working are referred to as ‘processing’, where the word is used to describe otherwise invisible stages of working through which the collected material starts to give birth to relevant sets of themes that emerge from the music and its performance practices. During a musician’s decades of processing, the encountered ’alien’ musics and cultures are appropriated and incorporated into his or her own musical identity.

It is typical that in the practising/rehearsal period, the arising themes begin to grow connections to each other as well as outwards to the ’world’. These connections and relationships, their mutual dynamics and causalities, may be explored and analysed. The multidisciplinary and multistage processing and analysis of the material (finding, collecting, producing, practising/rehearsing, delivering and performing) could be called artistic research or practice-based research.

For a musician, Paris is like a university of the mind from which one can never graduate.
A City Never Lies – Situational Irony and the Political Impact of Public Urban Space.
Authors: Denise Ziegler
Published: August 2017

In this text, I question the concepts of urban space and public art. Experimental artistic interventions are conducted using situational irony as a method for reflecting on the impact urban public space and its user can have. Instead of interrogating people and involving them in the process, the interventions put questions directly to public infrastructure, to walls, fences, buildings and pedestrian ways. In a post-Beuysian vein, an artist workshop is extended to public space in order to work with its mechanisms and possibilities. This is considered a political act. The research aims to contribute to the redefinition of concepts regarding how we look at and develop public urban space.
Practicing art - as a habit? / Att utöva konst - som en vana?
Authors: Annette Arlander
Published: August 2017

This bilingual exposition (English and Swedish) presents and problematizes the relationship between artistic practice and habit, describing two projects that deal with repetition and place. The projects 'Solsidan' and 'Summer at Söder' were undertaken during the years 2015-2016 in Stockholm. The idea of repetition and returning to the same site were crucial, as in much of my previous works. Unlike them, neither of these two projects involved performances for camera; in both the actual practice consisted of video recording the view. The shift in emphasis from an artistic practice aiming to produce an artwork, into an activity undertaken mainly as an exercise, an activity, could be seen as a strand in the general trend in contemporary art since the 1960s and accentuated in this century towards valuing the 'working' of art above the work of art as an object. This trend can also be related to research and linked to the preference for various terms like practice as research, performance as research, creative arts research or, indeed, artistic research. - This exposition combines a description of the actual practice, with an encounter with the material generated through that practice and proposes that these works can exemplify artistic research as a speculative practice.
Deliberately Practicing the Saxophone
Authors: Per Anders Nilsson
Published: August 2017

A point of departure in this exposition is the author’s experience of practicing and playing on the saxophone for more than 30 years. In particular, three aspects of practicing a musical instrument are discussed: firstly, development and maintenance of general skills; secondly avoiding stagnation and so-called arrested development, and thirdly practicing for specific events. These aspects of practicing are elucidated thru long time personal experience from playing and practicing the saxophone. The saxophone is an acoustic instrument where its properties are given by design and acoustics, and it is up to the player to master and perhaps extend its playing possibilities to its physical limits. Noteworthy, parts in this article is taken from the author’s thesis A Field of Possibilities (Nilsson, 2011), however practicing examples are either reworked or new, and reformatted for this context. In my thesis, which treats designing and playing digital musical instruments, the purpose of discussing the saxophone was about to create a background, something else, as contrast to the main subject. In this exposition practicing the saxophone is at the forefront, however written with more than 15 year’s experience of deliberately practicing electronic musical instruments of various kinds as a background.
Harjoitus, jossa tekijä vapautuu ja eettinen yhteisöruumis astuu esiin
Authors: Minna Heikinaho

”Tekijä etsii kotia. Avoin kirje minulta teille muille. Harjoitus, jossa tekijä vapautuu ja eettinen yhteisöruumis astuu esiin” -ekspositio käsittelee yhteisötaiteen tekijyyttä ja sitä, mistä se muodostuu. Miten voisimme synnyttää yhteistä ja jaettua tekijyyttä, miten voisimme vapauttaa tekijyyden taiteellisin menetelmin? Teksti pureutuu nykypäivän taiteilija-tekijän toimintakontekstiin, esittämisympäristöön – siihen miten elinympäristömme teknologistuu ja miten se vaikuttaa meihin, meissä ja meistä käsin. Kirjoittaja kysyy miten poliittinen ja kriittinen ote artikuloituu taiteellisessa toiminnassamme ja tutkimuksessamme. Mihin asemaan taide ja sen koettavuus asettuvat kun informaatio (kuvavirta), ihmisubjekti (fyysisesti läsnäoleva keho) ja virtuaaliteknologia kiistelevät paikastaan globaalissa ja muuttuvassa maailmassa.
Those Lips Were Made to Suck that Button
Authors: Taina Riikonen
Published: August 2017

In this liquid text/sound, the act of recording breastfeeding is explored in terms of artistic research as machinic liminality and embodied listening. In line with Felix Guattari’s notion of a machine as a prerequisite of technology, the highly intimate recording of neonatal nutrition is explored as an artistic inquiry, which is dependent on the interconnecting processes of the machinic assemblage (the coupling of a baby and a breast). Listening to breastfeeding through the headphones with a microphone touching the skin, produces a particular technology of recording that is noisy in its radical exclusion of other sounds, temporalities and spaces, as well as in its endless counter-oscillation and intrusiveness. The theoretical rhizomes of the article draw from the work of Luce Irigaray, Felix Guattari and Jean-Luc Nancy. The qualities of recording the breastfeeding are analysed through visceral parameters based on touch, embodied listening, and recording as a corporeal-political activity.
Relación entre estilos de manejo de conflictos y empatía multidimensional en adolescentes bachilleres / The relationship between conflict management styles and multidimensional empathy in adolescent high-school students
Authors: Luna-Bernal Alejandro César Antonio
Published: August 2017

El presente trabajo se propuso generar nuevos conocimientos acerca del papel de la empatía en la dinámica de los conflictos interpersonales de los adolescentes considerando, en este caso, las interacciones entre pares en el contexto escolar. Con esa finalidad, este estudio tuvo como objetivo evaluar la relación entre los estilos de manejo de conflictos que los adolescentes informan emplear en los conflictos cotidianos con sus compañeros de aula en el bachillerato, y la empatía, considerando ésta desde un enfoque multidimensional. Participaron 194 estudiantes de bachillerato con edades entre 15 a 18 años, quienes respondieron el Inventario de Rahim sobre estilos de manejo de conflictos y el índice de reactividad interpersonal. Se llevó a cabo un análisis correlacional Pearson entre las variables señaladas. En los resultados se encontró que la toma de perspectiva presentó correlaciones positivas estadísticamente significativas con los estilos complaciente, evasivo, comprometido e integrativo del modelo de Rahim. Asimismo, la preocupación empática presentó correlaciones positivas estadísticamente significativas con los estilos complaciente e integrativo. Se discuten estos resultados en el marco del modelo de doble preocupación sobre estilos de manejo de conflictos, y del modelo de Davis sobre empatía multidimensional.
