Mapping an Existential Territory
Authors: Wang Jing
Published: January 2015

This autoethnography explores how spaces of what we call home and ethnographic field shape subjectivity. From stories of growing up in Northwest China, studying in the humanities in the United States, and conducting ethnographic research in China's sound scene, I reflect on moments of shifts and ruptures, connections and disconnection that are brief but intense and transformative for fabricating subjectivity. Adaptation is an affective process; sensual elements including sound, smell, and taste underlie linguistic and cultural negotiations. An existential territory is ecological and processual. It is where one reinvents the self, achieves a self-feeling unicity and, most importantly, where one feels alive.

Authors: Ortiz Grisales Sanín , Valdés Restrepo Magda Piedad , Vallejo Cabrera Franco Alirio , Baena García Diosdado
Published: January 2015

A genetic correlation and path analysis was carried out for yield and fruit quality components of diallel crosses of butternut squash Cucurbita moschata Duch, using open-pollinated introductions, S0 and inbred lines S1 and S2 at two sites: Candelaria and Buga, located in the Department of Valle del Cauca, Colombia. A split-plot experimental design with arranged, random blocks and four replicates was used. The average fruit weight presented positive genetic correlations with the total production per plant in all three generations and at both test sites. The total plant dry matter and total production per plant presented a high genetic correlation, and the fruit dry matter was inversely correlated with the total carotene. The total carotene and fruit color were independent. The path analysis confirmed high genetic correlations between the number of fruits per plant, average fruit weight, and total plant dry matter, with direct, positive effects, that were significantly greater than zero for the variables of number of fruits per plant and average fruit weight in regards to the total plant dry matter. The total production per plant expressed a direct, negative effect on the total plant dry matter. The fruit dry matter presented an indirect, negative effect on the total plant dry matter through the average fruit weight and an indirect, positive effect through the total production per plant.

Authors: Villamil Carvajal Jorge Enrique , Viteri Rosero Silvio Edgar , Villegas Orozco William Luciano
Published: January 2015

En Colombia, las pérdidas ocasionadas por Moniliophthora roreri Cif & Par en el cultivo de cacao continúan siendo considerables. El objetivo del presente estudio fue investigar la actividad antagónica de dos aislamientos autóctonos de Trichoderma sp. y uno de Bacillus sp. ante M. roreri, en condiciones de campo. Los tratamientos fueron: T1, hongo H5; T2, hongo H20; T3, bacteria B3 y T4, testigo. Se evaluó incidencia y severidad externa e interna en los frutos. Los resultados de severidad externa e interna mostraron que respecto al control la disminución del daño en los frutos fue del 19,5 y 11,2% en el T1, del 28 y 19,5% en el T2 y del 13,5 y 8,5% en el T3, respectivamente con diferencias estadísticas a favor del T2. Se concluye que entre los tres antagonistas evaluados, el hongo H20 (Trichoderma sp.) tiene el mayor potencial para el control de la moniliasis del cacao en condiciones de campo.
Can the Wet – State Conductivity of Hydrogels be Improved by Incorporation of Spherical Conducting Nanoparticles?
Authors: Schirmer Katharina , Wright Cody , Warren Holly , Thompson Brianna , Quigley Anita , Kapsa Robert , Wallace Gordon
Published: January 2015

In nerve and muscle regeneration applications, the incorporation of conducting elements into biocompatible materials has gained interest over the last few years, as it has been shown that electrical stimulation of some regenerating cells has a positive effect on their development. A variety of different materials, ranging from graphene to conducting polymers, have been incorporated into hydrogels and increased conductivities have been reported. However, the majority of conductivity measurements are performed in a dry state, even though material blends are designed for applications in a wet state,in vivoenvironment. The focus of this work is to use polypyrrole nanoparticles to increase the wet–state conductivity of alginate to produce a conducting, easily processable, cell–supporting composite material. Characterization and purification of the conducting polymer nanoparticle dispersions, as well as electrochemical measurements, have been performed to assess conductivity of the nanoparticles and hydrogel composites in the wet state, in order to determine whether filling an ionically conducting hydrogel with electrically conductive nanoparticles will enhance the conductivity. It was determined that the introduction of spherical nanoparticles into alginate gel does not increase, but rather slightly reduces conductivity of the hydrogel in the wet state.
Mechanically Activated Combustion Synthesis of Molybdenum Silicides and Borosilicides
Authors: Alam Mohammad S. , Esparza Alan A. , Shafirovich Evgeny
Published: January 2015

Molybdenum silicides and borosilicides are promising structural materials for advanced power plants. A major challenge, however, is to simultaneously achieve high oxidation resistance and acceptable mechanical properties at high temperatures. For example, molybdenum disilicide (MoSi2) has excellent oxidation resistance and poor mechanical properties, while Mo-rich silicides such as Mo5Si3 (called T1) have much better mechanical properties but poor oxidation resistance. One approach is based on the fabrication of MoSi2−T1 composites that combine high oxidation resistance of MoSi2 and good mechanical properties of T1. Another approach involves the addition of boron to Mo-rich silicides for improving their oxidation resistance through the formation of a borosilicate surface layer. In particular, Mo5SiB2 (called T2) phase and alloys based on this phase are promising materials.

In the present paper, MoSi2−T1 composites and materials based on T2 phase are obtained by mechanically activated self-propagating high-temperature synthesis (MASHS). To obtain denser products, the so-called SHS compaction (quasi-isostatic pressing of hot combustion products) has been employed. Thermal analysis has shown that SHS compaction significantly improves the oxidation resistance. Self-sustained combustion of Mo/Si/B mixtures for the formation of T2 phase becomes possible if the composition is designed for adding a more exothermic reaction of MoB formation. These mixtures exhibit spin combustion. Oxidation resistance of the obtained multi-phase Mo−Si−B materials is independent on the concentration of Mo phase in the products. The “chemical oven” technique has been used to obtain a single Mo5SiB2 phase and an alloy consisting of α-Mo, Mo5SiB2, and Mo3Si phases.
Microstructure and Phase Transformation Temperatures of Two-Phase FeAl (B2) + FeAl2 Alloys
Authors: Li Xiaolin , Palm Martin , Scherf Anke , Janda Daniel , Heilmaier Martin , Stein Frank
Published: January 2015

Fe-Al alloys with about 55 to 65 at.% Al undergo a eutectoid transformation at 1095 °C: Fe5Al8 (ε) ↔ FeAl + FeAl2. Hence, as-cast Fe-Al alloys in this composition range show a very fine-scaled lamellar microstructure (average lamellar spacing below 500 nm) consisting of the two phases FeAl and FeAl2. The microstructure looks similar to the α2 + γ lamellar microstructure of Ti-Al-based alloys, which is known for having well-balanced properties in terms of creep, ductility and strength. However, there is limited knowledge about the properties of Fe-Al-based alloys in this composition range. In this study, a series of as-cast as well as heat-treated Fe-Al alloys with compositions between 57 and 63 at.% Al were investigated. The microstructures and crystal structures were analysed by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The composition dependence of all transition temperatures was obtained by differential thermal analysis (DTA).
Osoba i przesłanie św. Franciszka
Authors: Prejs Roland
Published: January 2015

St. Francis is undoubtedly one of the most popular Christian saints. There are two different biographies of St. Francis. The biography by Thomas da Celano is a historical description of St. Francis` life although written according to the medieval hagiographical canons. St. Bonaventure was a theologian and philosopher first of all. He shows us St. Francis as a perfect follower of Jesus. The other biographies relied heavily on Vita prima, Vita secunda or Legenda maior. Notwithstanding the first biographies based on the very first documents and contemporary relations, some questions still linger. Nevertheless, St. Francis message is clear: equality of all before God, everyone is called for the evangelical life, evangelism through good example rather than through words alone. Important is an emulation the radical poverty of Jesus, fidelity and obedience to the Church, which is represented and guided by pope.
Brat – ojciec – matka. Specyfika braterstwa minoryckiego
Authors: Block Wiesław
Published: January 2015

The primary objective of this work is to offer a brief and orderly reflection on the way Francis of Assisi kept up fraternal life in the nascent Minorite brotherhood and on how he presents his experience of it. Although in his writings one does not come across a complete and systematic discussion on the life in the brotherhood, one can certainly find in them clear notions for identifying the particular type of evangelical life Francis envisioned. The idea of Minorite brotherhood is not limited to the community of the Friars Minor only but also extends to the whole creation, though for the most part he focuses on the relationship that has the scope of uniting the brothers from the four corners of the earth into a fellowship following in the footsteps of the poor and humble Jesus Christ. Structurally, the work is divided into two parts, the first of which describes the maturation of Francis’ attitude of being a brother (awareness of being a “brother” to entire humankind), while the second dwells upon the figure of mother, which is the prototype of fraternal relationships, according to the mind of Francis.
Mozarabowie a iberyjskie doświadczenie graniczności
Authors: Roszak Piotr
Published: January 2015

Historia mozarabów, którzy bronili swej chrześcijańskiej tożsamości w wyjątkowych okolicznościach historycznych i kulturowych po 711 roku (inwazja arabska na Półwysep Iberyjski), może stać się ciekawym przyczynkiem do rozważań nad multikulturalizmem i jego słabościami. Doskonały obraz walki o tożsamość pozostawiła liturgia hiszpańska, która w wielu tekstach euchologicznych (choćby analizowana w artykule msza pro tribulatis) podkreśla konieczności troski o własną świadomość. Intersubiektywność dokonująca się w liturgii rozumianej jako wymiana, commercium, a także oparcie na tradycji będącej twórczą kontynuacją, przekazywaniem, stały się fundamentem postawy mozarabów. Na kanwie historycznych opisów artykuł omawia trudności, z którymi boryka się współczesna Hiszpania w dobie „nowego laicyzmu”. Model multikulturalizmu okazuje się dla wielu myślicieli już niewystarczający i wymagający zdecydowanej korekty.
Duchowość osób konsekrowanych w świetle adhortacji Jana Pawła II Vita consecrata
Authors: Gogola Jerzy Wiesław
Published: January 2015

Refleksja uwzględnia problematykę zawartą w temacie, skupiając się na jego trzech zasadniczych składowych: koncepcji duchowości życia konsekrowanego, jego tożsamości, z której wynika styl życia i działania powołanych w myśl zasady: „agere sequitur esse”, oraz na jej reprezentacyjnych cechach sprowadzonych za przykładem struktury adhortacji Vita consecrata do trzech: konsekracja, komunia i misja. Duchowość traktujemy jako przejaw ducha ucznia Chrystusa wezwanego szczególnym powołaniem do radykalnego pójścia za Nim drogą zakonnej konsekracji. Ponieważ jest to także zewnętrzny przejaw ducha, istotna jest tożsamość osoby, która powinna egzystować w sposób „godny powołania”, a przez to dawać świadectwo zbawczej obecności Boga w dzisiejszym świecie w sposób niemal bezwiedny. Trzy cechy charakterystyczne duchowości osoby konsekrowanej określają jednocześnie jej tożsamość: osoba oddana przez śluby rad ewangelicznych Bogu; osoba komunii z Bogiem i braćmi oraz prorok-świadek wielkich dzieł Bożych, które realizują się w słabym człowieku. Całość wieńczy krótka synteza, która może stanowić jedynie pewną wskazówkę na temat tej złożonej rzeczywistości i zaproszenie do budowania tej syntezy na płaszczyźnie egzystencjalnej przez poszczególne osoby konsekrowane i ich wspólnoty.

Authors: Machniak Jan
Published: January 2015

Private notes of Karol Wojtyła – John Paul II just on the moment of death of their author excited big interest between the people. The pope wrote in the testament, his secretary Msgr. Dziwisz has to fire all the documents, he left. Card. Stanisław Dziwisz didn’t accomplish the will of pope, because he was convinced, it is very important document, showing the interior life of John Paul II. Recently, the Publishing House Znak printed this Private notes (Krakow 2014) giving to the publicity to know the spiritual life of Karol Wojtyła – John Paul II. The Private notes are some kind of “diary of the soul” showing deeper life with God of Karol Wojtyła as bishop of Krakow, cardinal and pope. They are giving the possibility to enter in the mystery of the soul of John Paul II, to know his life of prayer, meditation and his relation to God and to Blessed Virgin Mary.
Pastoralne implikacje encykliki Jana Pawła II Sollicitudo rei socialis
Authors: Nadbrzeżny Antoni
Published: January 2015

Kanonizacja Jana Pawła II stanowi bardzo dobrą okazję do ponownego odkrycia wartości społecznej myśli papieża. W niniejszym artykule autor podejmuje kwestię duszpasterskich implikacji encykliki Sollicitudo rei socialis wydanej w 1987 roku. W pierwszej części omawia genezę i społeczno-polityczny kontekst papieskiego dokumentu. W drugiej części prezentuje najważniejsze idee zawarte w encyklice. Analizuje panoramę problemów współczesnego świata, przedstawia integralne rozumienie rozwoju człowieka oraz wskazuje na relacje między solidarnością i pokojem. W trzeciej i zarazem ostatniej części artykułu autor podkreśla aktualność wielu aspektów przesłania zawartego w encyklice oraz formułuje konkretne wskazania dla duszpasterstwa parafialnego. Zwraca uwagę na konieczność dowartościowania społecznego aspektu Eucharystii oraz na potrzebę kształtowania u wierzących postawy solidarności i odpowiedzialności za pełny rozwój człowieka zarówno w wymiarze indywidualnym, jak i wspólnotowym.
Hieronimowa krytyka pelagianizmu w Dialogu przeciw pelagianom
Authors: Mularczyk-Budzan Anita
Published: January 2015

Sam fakt krytyki zjawiska pelagianizmu przez Hieronima nie był niczym odkrywczym, oryginalnym. Idzie on bowiem po linii, którą prezentuje choćby św. Augustyn. Jednakowoż na szczególną uwagę zasługuje sposób, w jaki to czyni, specyfika jego podejścia. Strydończyk miał okazję zetknąć się z Pelagiuszem i jego poglądami wcześniej aniżeli biskup Hippony i od samego początku był na nie wyczulony. W swoich wypowiedziach nie waha się używać kontrowersyjnych, mocnych argumentów. Jednocześnie jest mistrzem pięknych, kwiecistych sformułowań. Wielokrotnie jest w swych teologicznych rozważaniach niekonsekwentny. Prawdopodobnie dlatego nie cieszy się dużą popularnością wśród współczesnych teologów. Niniejsza publikacja jest próbą ukazania reakcji Hieronima na herezję pelagiańską i samego Pelagiusza przede wszystkim w oparciu o Dialog przeciw pelagianom oraz Listy, z zastosowaniem metod teologicznej, historycznej oraz filologicznej. W pierwszej kolejności omówiono najważniejsze problemy teologiczne, o których pisał Strydończyk. Następnie nakreślono cechy szczególne podjętej przez niego krytyki pelagianizmu, po czym ukazano tę krytykę w kontekście szeroko rozumianego nurtu teologii łaski w Kościele zachodnim pierwszej połowy V wieku.
Marcin Bucer jako pionier reformacyjnego pojednania
Authors: Medwid Wojciech
Published: January 2015

Artykuł dotyczy życia i dzieła Marcina Bucera, protestanckiego reformatora związanego ze Strasburgiem. Jego życie było wielką próbą uzdrowienia rosnącej przepaści pomiędzy dwoma czołowymi reformatorami – Marcinem Lutrem i Huldrychem Zwinglim, zwłaszcza w kwestii Eucharystii oraz pojednania protestantów i katolików. Bucer wywarł wpływ na luterańskie, kalwińskie i anglikańskie doktryny i praktyki. Pierwotnie był dominikaninem, ale potem rozpoczął pracę na rzecz reformacji. Stał się zagorzałym wielbicielem Erazma, a wkrótce entuzjastycznym uczniem Lutra. Wierzył, że katolicy mogą przyłączyć się do reformacji. W Strasburgu jego działalność obejmowała wiele sfer. Stał się głównym reformatorem miasta i miał udział w wielu ważnych wydarzeniach religijno-politycznych tego okresu. Bucer zajął się nowym obrzędem mszy i dyscypliny kościelnej. W Anglii pomógł w reformie Kościoła lokalnego i nowego modlitewnika. Bardziej zależało mu na dialogu i pozyskaniu swoich przeciwników niż na walce o teoretyczne kwestie doktrynalne. Dla jasnego określenia doktryny zawsze był gotów zrezygnować z niejasnej formuły na rzecz jedności. Jego działalność nie doprowadziła do powstania nowego odłamu protestantyzmu. Został zapamiętany jako jeden z pierwszych pionierów ekumenizmu.
Duszpasterska opieka i głoszenie Dobrej Nowiny Chrystusa rodzicom dzieci zmarłych przed urodzeniem
Authors: Sławiński Henryk
Published: January 2015

Artykuł opisuje zmiany w duszpasterstwie Kościoła uwarunkowane zmianami w zakresie opinii teologów katolickich na temat losu dzieci, które zmarły bez chrztu. W okresie, w którym dominujące opinie o losie dzieci zmarłych bez chrztu mówiły o piekle lub przynajmniej pozbawieniu uszczęśliwiającej wizji Boga, niemożliwe było głoszenie Dobrej Nowiny o zbawieniu w Jezusie Chrystusie. II Sobór Watykański dał decydujące impulsy do zmiany opinii teologicznej w omawianej kwestii. Obecnie teologowie katoliccy podkreślają nadzieję na zbawienie dzieci, które zmarły bez chrztu. Podstawą tej nadziei są: powszechna zbawcza wola Boga, miłość Jezusa do dzieci, śmierć Chrystusa za wszystkich, nieograniczone miłosierdzie Boga, który w sposób znany tylko sobie może podarować zbawienie dzieciom zmarłym bez chrztu. Inspirowane przez II Sobór Watykański zmiany w prawodawstwie kościelnym oraz obrzędy liturgiczne odnowione na podstawie nauczania soborowego pozwalają aktualnie pochować nieochrzczone niemowlęta i celebrować obrzęd chrześcijańskiego pogrzebu przewidziany dla nich, a także odprawić mszę świętą specjalnie przygotowaną na taką okazję. Wszystkie te argumenty pozwalają głosicielom słowa Bożego zwiastować Dobrą Nowinę rodzicom opłakującym utratę dziecka, które zmarło bez chrztu.
Nostra aetate – stages of creation, with a particular focus on paragraph no. 2… and the people involved in its development
Authors: Dupuche John
Published: January 2015

Nostra aetate began as an important statement concerning the relations of the Church with the Jews but soon developed into a highly significant text on the relationship of the Church to all the religions of the world. While there been many works on the theology of Nostra aetate, there are few studies that present in detail the major personages and stages, the crucial issues and opposing forces surrounding this prophetic document. This article seeks to address this lacuna.The article also gives special attention to key phrases from paragraph 2 that show an extraordinary shift from millennial attitudes, among which “the Church does not reject what is truly and holy in these religions”.Finally it goes on to show how the wholesale rejection of Nostra aetate by the Society of St Pius X has led to schism.

Observations on the urban ecology of the Neotropical stingless bee Tetragonisca angustula (Hymenoptera: Apidae: Meliponini)
Authors: Velez-Ruiz Rita I. , Gonzalez Victor H. , Engel Michael S.
Published: January 2015

Tetragonisca angustula (Latreille) is a small, docile, cavity-nestingstingless bee that is widely distributed in the Neotropical region. This speciesis particularly abundant in disturbed environments, including humansettlements. Between August 2005 and March 2006, we located and followed duringeight months 59 nests of this species in Medellín, the second most populatedcity in Colombia. Herein, we document their foraging behavior, mortality, andincidence of predators and natural enemies. Also, to determine if higherambient temperature and light intensity in urban environments affect the dailyforaging activity of T. angustula, wecompared the daily foraging activity of bees from nests found in open areas in thecity and bees from nests from a nearby covered, forested area. Likewise, todetermine if urban nests of T. angustulaare largely undetected and undisturbed by people, we experimentally made themvisible by adding a ring color (white, red, or black) around the nest entrance tube.Our observations indicate that higher ambient temperature and light intensity inurban environments do not significantly affect the daily foraging activity of T. angustula. Nearly half of the markednests disappeared, thus suggesting that nests of T. angustula are often undetected by people in Medellín. We discussbriefly some features of the biology of T.angustula that might contribute to its success in urban environments.

In the Brazilian state of Rio Grande do Sul, rice (Oryza sativa L.) is predominantly grown using continuous flood irrigation, which requires large quantities of fresh water. Due to increasing scarcity and demand for water, modern agricultural systems need to produce more food with less water. The objective of this study was to evaluate the effect of different irrigation management systems on water use efficiency, quantity of water loss due to runoff, and rice grain yield. The experiments were conducted from 2007 through 2010 at an experimental station of the Plant Protection Department of the Universidade Federal de Santa Maria, Rio Grande do Sul state, Brazil, on an Albaqualf sandy‐loam soil. Treatments consisted of two irrigation management systems: continuous flooding (CF) at approximately a 10‐cm flood depth and intermittent irrigation (II) where the flood was allowed to fully subside before being re‐established to a 10‐cm depth. Intermittent irrigation increased storage of rainwater by reducing runoff water by 56% compared with CF. In addition, II reduced irrigation water use by 22 to 76% resulting in a 15 to 346% increase in water use efficiency (WUE). Rice yield was not affected by II compared with CF. Intermittent irrigation provides greater water conservation, does not reduce rice yield compared with CF, and improves the WUE of rice.
Using Canopy Indices to Quantify the Economic Optimum Nitrogen Rate in Spring Wheat

Published: January 2015

In‐season N applications to spring wheat (Triticum aestivumL.) may increase profits and improve N fertilizer accuracy. The objectives were to develop a calibration tool employing normalized difference vegetative index (NDVI) and SPAD 502 chlorophyll meter (SPAD) measurements for calculating the differential from the economic optimum N rate (dEONR) at growth stages Z22, Z24, and Z31 to Z39 and provide N rate algorithms for use in applying N fertilizer at a variable rate. Sensing was conducted trials over 3 yr encompassing 10 site‐years across Southeastern Buenos Aires Province, Argentina. The relationship between sensor indices and dEONR was evaluated by fitting quadratic plateau (QP) regression models. Statistically significant QP models were determined at the Z24, Z31, and Z39 growth stages. Relative SPAD (rSPAD) and relative NDVI (rNDVI) reduced variation and improved the calibration of measured N stress with the dEONR. For Z31 and Z39, the rSPAD had the best goodness of fit statistics when compared to rNDVI [adjustedR2(adjR2)= 0.67 and 0.57 at Z31 and 0.68 and 0.52 at Z39, respectively]. However, adjustment at Z24 was higher for rNDVI (adjR2= 0.53 and 0.61 for rSPAD and rNDVI, respectively). A single QP model to estimate the dEONR with 58% confidence was adjusted for the Z31 and Z39 growth stages. This indicates that the same calibration for N rate determination based on rSPAD or rNDVI values can be used during stem elongation in spring wheat. This model can be used as an N rate algorithm for applying N fertilizer in‐season.

Knowledge about how stand age affects N response in first‐year corn (Zea mays L.) following alfalfa (Medicago sativa L.) is needed to improve N credit predictions. In a 3‐yr study, we evaluated response to N in first‐year corn following fall‐terminated 1‐ to 3‐yr‐old alfalfa stands with stand densities of 33 to 579 plants m−2 at Lamberton and Waseca, MN, each year. At both locations, alfalfa stand age had minor impacts on soil inorganic N content and aboveground corn dry matter (DM) yield, N concentration, and N uptake during first‐year corn. On medium‐textured soil at Lamberton, first‐year corn following 3‐yr‐old alfalfa stands required no fertilizer N to economically optimize grain yield, but required 64 and 97 kg N ha−1 following 2‐ and 1‐yr‐old stands, respectively, at the fertilizer cost (US$ kg−1 N)/corn grain price ($ kg−1 grain) ratio of 5.6. At the same price ratio on fine‐textured soil at Waseca, first‐year corn required 94 kg N ha−1 following both 2‐ and 3‐yr‐old stands and 118 kg N ha−1 following 1‐yr‐old stands. Therefore, current alfalfa N credit guidelines from land‐grant universities that are based on alfalfa stand density at termination were not accurate for alfalfa stands ≤3 yr old that frequently had high densities. These results also confirm that alfalfa stand age affects the frequency and level of fertilizer N response in first‐year corn, and support the role of soil texture in altering the effect of stand age.

Published: January 2015

Growing complexity of water monitoring instrumentation leads to specialized solutions in respect to sensor integration across several measurement device suppliers. Despite efforts of standardization for data interfaces and protocols, problems regarding the combination of several devices to gain the complete picture in terms of water quality remain. This assessment, especially accomplished from the perspective of a catchment area, requires a transition from sole use of data collectors toward an implementation of intelligent measurement networks. Several challenges and bottlenecks concerning distributed data collection are discussed starting with data acquisition up to the user-scope of utilizing data processing software. Finally, experiences using automated data inspection and export tools are discussed and a brief overview of expectable long-term data availability is given.
Multi-chamber microbial desalination cell for improved organic matter and dissolved solids removal from wastewater
Authors: Pradhan Harapriya , Ghangrekar M. M.
Published: January 2015

A five-chamber microbial desalination cell (MDC) with anode, cathode, one central desalination chamber and two concentrate chambers separated by ion exchange membranes was operated in batch mode for more than 60 days. The performance of the MDC was evaluated for chemical oxygen demand (COD) removal, total dissolved solids (TDS) removal and energy production. An average COD removal of 81 ± 2.1% was obtained using acetate-fed wastewater as substrate in the anodic chamber inoculated with mixed anaerobic sludge. TDS removals of 58, 70 and 78% were observed with salt concentration of 8, 20 and 30 g/L, respectively, in the middle desalination chamber. The MDC produced a maximum power output of 16.87 mW/m2 during polarization. The highest Coulombic efficiency of 12 ± 2.4% was observed in this system using mixed anaerobic sludge as inoculum. The system effectively demonstrated capability for simultaneous organic matter removal and desalination along with power generation.

Published: January 2015

This study proposes the use of bentonite modified with l-histidine for the removal of Cu, Co, Cr, Fe, Hg, Ni, U and Zn from aqueous solutions such as those impacted by acidic drainage. The surface areas of natural bentonite and bentonite–histidine were 73.8 and 61.2 m2 g−1, respectively. Elemental analysis showed an increase in the amount of carbon (0.258%) and nitrogen (0.066%) for the bentonite–histidine. At a fixed solid/solution ratio, the operating variables affecting the adsorption of metal ions from aqueous solution such as pH, initial concentration, contact time and temperature were studied in batch mode. The Freundlich isotherm model yielded a better fit than the Langmuir for the adsorption of Cu, Co, Ni and Zn, implying adsorption on a heterogeneous surface. Adsorption kinetics followed a pseudo-second-order model, suggesting chemisorption as the rate-limiting step. The apparent activation energy was greater than 40 kJ mol−1 for Cu, Zn, Ni, Co and U, which is characteristic of a chemically controlled reaction. Thermodynamic constants ΔG and ΔH showed that the adsorption of metals was endothermic and spontaneous. Adsorption of heavy metals onto bentonite–histidine was efficient at low pH values, meaning that the adsorbent could be useful for remediating acid mine water.
Stillness as a Form of Imaginative Labour
Authors: Kyriakides Theodoros
Published: January 2015

This essay connects the practice of stillness to David Graeber's concepts of imaginative labour and immanent imagination. It makes the proposition that stillness should not be evaluated as lack of activity or movement, but rather attended to in its pragmatic and productive dimensions. The essay thus explores stillness as a potential mode of production of imagination and means of political transformation: in order for it to be meaningful, we need to reconfigure our relationship to stillness as one of imagination, resistance, thinking, and writing.
Designing an Illusion of India’s Future Superpowerdom
Authors: Kuldova Tereza
Published: January 2015

The article dissects current utopian visions of future Indian superpowerdom and traces them to underlying convergences between right wing political Hindu nationalism and philanthrocapitalism. By looking at how utopian visions are materialized in the elitist aesthetics of ‘royal chic’ parading on New Delhi’s fashion ramps and in the aesthetics of hypermodern smart cities of the future, the article explores the aesthetic and affective convergence of an imagined economy and (re-)invented traditions. In the problematic terrain of philanthrocapitalism, the ‘factish’ of GDP and the doxa of Indianness have come to form the core of current populist myths. In so doing they produce an illusion of future India that nobody really believes in, yet structures reality and is passionately embraced by many. The article suggests that the problem with such utopian myths is not that they are myths, but rather it is the direction they are pushing in and their consequences which require questioning. The article provides preliminary analysis of, and answers around, this problematic of resonant versus dissonant futures and their imaginaries.
Two attempts at grounding social critique in „ordinary“ actors’ perspectives: The critical theories of Nancy Fraser and Axel Honneth
Authors: Ivkovic Marjan
Published: January 2015

This paper analyzes two contemporary, ?third-generation? perspectives within
critical theory - Nancy Fraser?s and Axel Honneth?s - with the aim of
examining the degree to which the two authors succeed in grounding the
normative criteria of social critique in the perspectives of ?ordinary?
social actors, as opposed to speculative social theory. To that end, the
author focuses on the influential debate between Fraser and Honneth
Redistribution or Recognition? which concerns the appropriate normative
foundations of a ?post-metaphysical? critical theory, and attempts to
reconstruct the fundamental 29 disagreements between Fraser and Honneth over
the meaning and tasks of critical theory. The author concludes that both
critical theorists ultimately secure the normative foundations of critique
through substantive theorizations of the social, which frame the two authors?
?reconstructions? of the normativity of everyday social action, but argues
that post-metaphysical critical theory does not have to abandon comprehensive
social theory in order to be epistmologically ?non-authoritarian?.
The possibility of a critique of domination in the theory of Luc Boltanski
Authors: Biresev Ana
Published: January 2015

The author examines the possibility for a rapprochement between Luc
Boltanski?s sociology of critique and Bourdieu?s critical sociology of
domination by analyzing three subjects within the theoretical opus of Luc
Boltanski: the place given to tests in the critical agency of actors, the
relation between critique and institutions, and the role the collective plays
in the appropriation and distribution of critique. In Boltanski?s works the
question of the sense of justice and the critical capacities of actors, that
is injustice and its critique, is approached with full respect for the
perspectives of the social actors. In his book On Critique the French
sociologist writes about domination, or more precisely, the process of
domination, but he doesn?t fully answer the question wether and how the
capacities of social actors for critique can be realized and elevated to the
level of a full-fledged critique of domination. This is considered to be the
main condition of the possibility for connecting critical sociology and
sociology of critique, so the analysis of the three mentioned topics should
76 determine whether the social actors within the theoretical world of Luc
Boltanski are relatively close to the stage of a critique of domination.
Problems of normative strenght and critique within the concept of agonistic participation: Towards the complementarity of agonistic and participatory democracy
Authors: Djordjevic Biljana
Published: January 2015

In this article I argue that there are grounds for considering agonistic
democracy and participatory democracy complementarity in order to
institutionalize agonism which has thus far lacked an elaborate articulation
of its institutional dimension. The two democratic theories share a
commitment toward widening the scope of the political as a way of inclusion
of citizens and their subsequent political subjectivation and empowerment.
Furthermore, there are authors on both sides who think democracy does not
need foundations. Agonistic participation and contestation, on the one hand,
and the broadening and strengthening of various sectors of political
participation, on the other, both open up new possibilities for critique and
change, but also create new risks. Building on a redefinition of agonisitic
participation, I aim to attenuate an objection that agonism is normatively
weak in terms of lacking resources to motivate citizens and justify their
critique of practices of domination and oppression. The article concludes
that we need to embrace agonistic participation as a means towards the
development of democratic political judgement, as there are no other
guarantees, i.e. secure foundations, for our ability to distinguish between
democratic and non-democratic agon.
The postwar capitalism
Authors: Mesec Luka
Published: January 2015

In this paper, I will try to offer a very concise overview of the development
of the capitalism after the World War II. Specific historical constellation
in the postwar period has enabled the development of Keynesian project in
response to the crisis of the Great Depression. However, due to the inherent
contradictions of the capitalist system, the Keynesian project has exhausted
itself by the beginning of the 1970s, which caused a new crisis. This opened
the way for the return of neo-liberal theory and neo-liberal policies that
dominates today.
What feminism owes to Marx and what Marxism owes to feminism?
Authors: Jovanovic Andrea
Published: January 2015

Feminist issue and Marxist issue mainly meet under the question of
reproduction of working class in capitalism. Among other things, the
existence of capitalist system is conditioned by possibility of, how Marx put
it, ?worker to show up at factory?s gates every day?. Traditional Marxist
analysis of this question entails taking wage as a main point. According to
this position, reproduction of a worker is thought only through a wage as
money paid to him for buying his/her labor force. It is at this point where
feminist perspective help us see narrowness of traditional Marxist analysis
by insisting on category of reproductive labor. Reproductive labor is unpaid
housework that is mostly done by women. Nonetheless, introduction of this
category is not just an addition to Marxist analysis since this labor is
necessary for reproduction of capitalist system itself. It is a system that
allocates labor in such a way that besides paid waged labor there also exists
unpaid reproductive labor that is also crucial for existence of the system.
This leads us to two complex problems: question of women?s emancipation in
capitalism and question of productivity of labor in capitalism.
Minimalbürger, Staatsbürger, Weltbürger
Authors: Höffe Otfried
Published: January 2015

Lange Zeit befa?te sich die Politische Philosophie vornehmlich mit sozialen
Institutionen und Systemen. Die Politik erschien dabei als eine
Auseinandersetzung mit Interessen und um Macht. Vernachl?ssigt wurden die
Subjekte, von denen in Demokratien doch alle politische Gewalt ausgeht.
Dieser Vernachl?ssigung steuert das Thema der B?rgeridentit?t entgegen. Das
entscheidende Subjekt, den B?rger, darf man allerdings weder auf den B?rger
im engeren Sinn, den Staatsb?rger, verk?rzen, noch bei diesem die
B?rgertugenden vergessen. Selbst wer den Staatsb?rger f?r den wichtigsten
Aspekt h?lt, darf die anderen Hinsichten nicht unterschlagen, zumal sie das
Staatsb?rgersein beeinflussen. Die B?rgertugenden wiederum tragen als
Rechtssinn, Gerechtigkeitssinn und Gemeinsinn zum Wohlergehen der Demokratie
bei, geh?ren deshalb zum Kern eines aufgekl?rten Liberalismus.
