Published: November 2017

Abstract
Magnetic nanosorbents proved to be highly effective in inorganic and organic contaminants removal from aqueous solutions, especially nano zero valent iron (nZVI). The main purpose of this study is to investigate the effect of using nZVI in removing benzene, toluene, ethyl benzene and xylene (BTEX) contaminants from aqueous solutions. The nZVI and the standard BTEX solution were prepared in the laboratory. X-ray diffraction (XRD), UV spectrophotometry, and scanning electron microscopy (SEM) analysis were used for nZVI characterization. The effects of contact time, initial BTEX mixture concentration, adsorbent dose, temperature, and pH on the amount of BTEX absorbed were investigated. The highest removal efficiency of 97% for the BTEX mixture was achieved at a stirring rate of 100 rpm, temperature of 60°C, and pH 7. The minimum effective time for efficient removal was 30 min, while the effective dose for BTEX compounds removal was 0.22 g/L. The Freundlich model was the best fit of experimental data. An artificial neural network (ANN) was used to predict the BTEX removal efficiency. Modeling results showed that ANN with average absolute error of 0.6272% is reliable in describing the adsorption of BTEX onto the iron nanoparticles. It is estimated that the cost of BTEX removal by nZVI under the optimal conditions will be about 3.5 USD per cubic meter.

Published: November 2017

Abstract
Up-flow anaerobic sludge blanket (UASB) has been in use since last few decades for the treatment of organic wastewaters. However, the performance of UASB reactor is quite low for treatment of low strength wastewaters (LSWs) due to less biogas production leading to poor mixing. In the present research work, a modification was done in the design of UASB to improve mixing of reactor liquid which is important to enhance the reactor performance. The modified UASB (MUASB) reactor was designed by providing a slanted baffle along the height of the reactor having an angle of 5.7° with the vertical wall. A two-dimensional computational fluid dynamics (CFD) simulation of three phase gas-liquid-solid flow in MUASB reactor was performed and compared with conventional UASB reactor. The CFD study indicated better mixing in terms of vorticity magnitude in MUASB reactor as compared to conventional UASB, which was reflected in the reactor performance. The performance of MUASB was compared with conventional UASB reactor for the onsite treatment of domestic sewage as LSW. Around 16% higher total chemical oxygen demand removal efficiency was observed in MUASB reactor as compared to conventional UASB during this study. Therefore, this MUASB model demonstrates a qualitative relationship between mixing and performance during the treatment of LSW. From the study, it seems that MUASB holds promise for field applications.
Effects of Olive Oil on TNF-α and IL-6 in Humans: Implication in Obesity and Frailty
Authors: Yarla Nagendra S. , Polito Angela , Peluso Ilaria 
Published: November 2017

Background and Objective:
Tumor necrosis factor-alpha (TNF)-α and interleukin (IL)-6 are
important mediators of chronic low-grade systemic inflammation. The latter plays a central role in
several obesity-related pathologies, such as diabetes, metabolic syndrome and cardiovascular diseases.
Besides, these cytokines have been also implicated in geriatric and cancer-induced anorexia, cachexia,
sarcopenia and frailty. Potential interventions for both obesity and frailty include dietary advice and
nutraceuticals. In this context, the consumption of olive oil (OO) has been associated with the health
effects of the Mediterranean diet (Med-diet). This review is aimed to discuss the OO-mediated modulation
of TNF- α and IL-6 in human studies and the potential implication in obesity and frailty.

Results:
The reviewed studies suggest that the improvement of postprandial TNF-α and IL-6 observed
with OO consumption is affected by body mass index (BMI). The effects on TNF-α and IL-6 after
medium and long-term consumptions involved many factors and the cross-talk between adipose tissue,
liver, skeletal muscle and brain. Major anti-inflammatory effects were observed when OO was consumed
with Med-diet, which is associated with healthy behaviors. In this context, the role of microbioma-
polyphenols, diet-gene and exercise-gene interactions in the effects of OO on immune-mediated
inflammatory responses involved in obesity and frailty deserves further investigation.

Conclusion:
Further studies are needed to clarify the effect of OO net of possible synergistic effects
with other dietary and lifestyle factors of Mediterranean area.
Ensaio Visual: Com quantas janelas? Homenagem a Ana Mae Barbosa
Authors: Barreto Umbelina 
Published: November 2017

Nós tentamos fazer uma homenagem a Ana Mae Barbosa partindo da poética de sua própria imagem em ação, mas isso não é uma tarefa fácil, principalmente, se pensarmos em como ela tem dedicado a sua vida a nos mostrar a importância da Arte na Educação. Percebendo a dificuldade que seria a criação de um ensaio significativo que contemplasse o tempo e o espaço é que ficamos somente a abrir janelas! As janelas compartilhadas com artistas, pesquisadores e arte educadores adquiriram horizontes com linhas sinuosas, hibridizadas, que, por vezes passaram ao som, nos levando da visão à audição, e, do som, conseguimos atingir também o aroma! Talvez os artistas surrealistas tenham também aberto janelas! Pois, é certo que com Magritte nós conseguimos sentir o cheiro do mar, e, com Max Ernst, tocamos a textura da terra. Mas, é somente com João Jardim que passamos a buscar a “Janela da alma”! E, é dessa forma que alguns vão orientar o seu olhar no ensaio em que homenageamos a Barbosa. Alguns caminhos da construção do olhar se darão de dentro para fora, outros de fora para dentro, e, é nesse vai e vem da construção dos percursos em que os sentidos vão multiplicando as janelas. Ana Mae Barbosa tem criado novas janelas e também tem nos levado a construir novas miradas. Com o GEARTE tentamos encontrar o tom, o tempo certo da grandeza de uma vida que sabe dar valor ao sonho no compasso da realidade de seu país.

Na costa do Amapá e da Guiana Francesa ocorreu o desenvolvimento de uma cultura pré-colonial que apresenta, como uma de suas características principais, a construção de monumentos megalíticos e a utilização de lugares naturais com formações rochosas, ambos utilizados para fins ritualísticos e/ou funerários. Embora diferentes em essência,estes tipos de sítios possuem uma estruturação similar dos depósitos, indicando que performances parecidas foram feitas em ambos os tipos de sítios, misturando elementosnaturais e culturais em uma espécie de “gramática” semelhante que se utiliza de potes ceramicos e pedras de granito ou laterita na construção de significados. Aqui apresentamos uma síntese do uso destes locais durante a pré-história tardia da região, procurando entender a natureza, forma e temporalidade das deposições de artefatos. A percepção da forma como estes grupos interagiram e modificaram a paisagem, ora de maneira bem visível, ora de forma sutil, contribui para discutirmos a construção de espaços sociais não-domésticos na Amazônia pré-colonial.

MODERNIST ARCHITECTURE, CONFLICT, HERITAGE AND RESILIENCE: THE CASE OF THE HISTORICAL MUSEUM OF BOSNIA AND HERZEGOVINA
Authors: Harrington Selma , Dimitrijević Branka , Salama Ashraf M. 
Published: November 2017

Bosnia and Herzegovina is one of the successor states of former Yugoslavia, with a history of dramatic conflicts and ruptures. These have left a unique heritage of interchanging prosperity and destruction, in which the built environment and architecture provide a rich evidence of the many complex identity narratives. The public function and architecture of the Historical Museum of Bosnia and Herzegovina, once purposely built to commemorate the national liberation in World War 2, encapsulates the current situation in the country, which is navigating through a complicated period of reconstruction and transformation after the war in 1990s. Once considered as the embodiment of a purist Modernist architecture, now a damaged structure with negligible institutional patronage, the Museum shelters the fractured artefacts of life during the three and a half year siege of Sarajevo. This paper introduces research into symbiotic elements of architecture and public function of the Museum. The impact of conflict on its survival, resilience and continuity of use is explored through its potentially mediatory role, and modelling for similar cases of reuse of 20th century architectural heritage.

Colletotrichum gloeosporioides (Penz.) Penz. & Sacc., es el agente causal de la antracnosis, una enfermedad que causa pérdidas considerables en la producción de frutos tropicales. El objetivo de este estudio fue evaluar extractos vegetales de plantas que crecen comúnmente en el estado de Puebla y que puedan inhibir a C. gloeosporioides. Extractos oleosos y etanólicos de hojas de capulín (Prunus serotina subsp. Capuli), no­gal (Juglans regia), pirul (Schinus molle), ruda (Ruta chalepensis) y marubio (Marrubium vulgare) fue­ron obtenidos, y se determinó la concentración mínima inhibitoria (CMI), empleando diferentes con­centraciones de extractos oleosos y etanólicos (150 a 2000 mg L-1). Con los resultados obtenidos de la CMI se evaluó el crecimiento radial a concentraciones menores y se ajustaron al modelo de Gompertz modificado para evaluar el crecimiento máximo en la fase estacionaria, la fase lag y la velocidad máxima de crecimien­to. Tanto los extractos oleosos de ruda (500 mg L-1) y capulín (750 mg L-1), como los extractos etanólicos de ruda (150 mg L-1) y pirul (300 mg L-1), presentaron la mayor inhibición sobre C. gloeosporioides, afectan­do significativamente (P< 0.05) las variables crecimiento máximo y velocidad de crecimiento radial (en un 60 % de reducción) del fitopatógeno.

Bacillus cereus es reconocido como un agente patógeno causante de intoxicaciones alimentarias. Se han presentado brotes asociados al consumo de arroz contaminado con ésta bacteria. Es uno de los pocos patógenos con capacidad de deteriorar los alimentos. En un brote ocurrido en 1994, en el Estado de Puebla, las personas afectadas manifestaron haber consumido arroz ácido o agrio. Se determinó la calidad sanitaria de 50 muestras de arroz cocido recolectadas en diferentes establecimientos de la ciudad de Puebla (hogares, fondas, tortillerías y supermercados). El recuento de B. cereus se realizó en el agar MYP (manitol, yema de huevo polimixina), los recuentos de bacterias mesofílicas aerobias y bacterias coliformes totales, se realizaron siguiendo la metodología oficial vigente. Se obtuvieron recuentos elevados de bacterias mesofílicas aerobias (> 106 UFC/g) en el 22 % de las muestras, y en el 44 % se demostró la presencia de bacterias coliformes totales. En el 10 % de la muestras se recuperó B. cereus. Aun en cifras muy por debajo de las consideradas como un riesgo para la salud, si se almacena enCondiciones de abuso de temperatura, como suele ocurrir en los sitios muestreados el arroz contaminado puede representar un riesgo a la salud del consumidor.
Partial Oxidation of Ethanol Using VOx/SBA-15 and VOx/Fumed Silica Catalysts in a Bench-scale Stainless Steel Reactor
Authors: Hidalgo-Herrador José Miguel , Tišler Zdeněk 
Published: November 2017

Two VOx/SBA-15 catalysts and three VOx/SiO2-fumed silica, with 5, 10 and 1, 5, 10 %wt. vanadium content respectively, were tested in a stainless steel continuous flow reactor for the partial oxidation of ethanol. The catalysts were tested at 150 – 300 °C. Products were analyzed by GC-FID, GC-OFID and GC-MS. The aim was exploring the problematics which could be found when more industrial close conditions are used. The total conversion of ethanol and selectivity to acetaldehyde were different than the expected ones. For VOx/SiO2-fumed silica, the total conversion was higher with a lower selectivity to acetaldehyde compared to VOx/SBA-15 catalysts.

Published: November 2017

Background Peritonitis is a major cause of peritoneal dialysis (PD) failure. Recommendations for the prevention of peritonitis are available, but wide variations exist in the peritonitis rate among countries and PD units. The objective of this study was to describe the different pattern of practices in France. Methods This was a retrospective, multicenter study based on data from the French Language Peritoneal Dialysis Registry. Center practices were described and mapped. Clusters of practices were sought in a hierarchical analysis and centers belonging to the same clusters of practices were mapped. Results Data from 2,770 catheters placed in 64 centers in France between 1 February 2012 and 31 December 2016 were considered. A median of 34 (ranging from 5 to 133) catheters was reported in each center. Twenty-eight (43.8%) centers routinely administered a prophylactic antibiotic prior to catheter placement, and 8 (12.5%) centers applied a local prophylactic antibiotic at the exit site, as recommended by International guidelines. The presence of a PD nurse specialized in PD or PD referent nephrologist was not associated with better adherence to guidelines. Practices were heterogeneous across centers. We identified 5 clusters of centers according to practice. Geographical proximity was not associated with homogeneity in practices. Conclusion Peritoneal dialysis practices are heterogeneous in France, even those that are subject to International guidelines. Studies to identify associations between center-specific practices and PD patient outcomes remain mandatory. Efforts should be made to standardize the PD standards of care in France.
