Enriching the injection water with CO2 has demonstrated promising results as a method for improving oil recoveries and securely storing CO2 in oil reservoirs. However, the mutual interactions taking place between carbonated water and reservoir oil at elevated reservoir conditions are not fully understood. Here we present the results of a thorough investigation of the processes leading to additional oil recovery through integrating pore-scale visualisations and coreflood experiments. Four pore-scale visualization (micromodel) experiments were performed at reservoir conditions using the recombined live oil under different injection scenarios (tertiary and secondary). Having identified the underlying dynamic interactions at pore-scales, the performance of different injection scenarios for carbonated water injection (CWI) was investigated using carbonate reservoir rocks. Five coreflood experiments were carried out using both fully and half-saturated carbonated water to sensitise the impact of CO2 content of injection water on the performance of CWI.

In-situ liberation of gaseous phase was identified (from direct visualisations) as the predominant mechanism controlling the performance of carbonated water injection. The gas phase formation would bring about higher degrees of oil swelling, and it would also create a three phase flow regime which leads to further reduction of residual oil saturation. The observations confirm that the performance of CWI should be investigated under reservoir conditions using multi-components live oil and reservoir cores. Any simplification, e.g. one components make-up gas or reduced pressure/temperature, of the reservoir conditions would misleadingly change the pore-scale event and hence, the performance of CWI. From the core displacement tests, it was observed that secondary CWI could recover a significant amount of additional oil, which was 26% compared to plain seawater injection. The tertiary carbonated water would effectively mobilise 15.3% of the residual oil (after seawater injection). When CO2 content of injected CW (carbonated water) was halved, the oil recovery dropped by 13. The results revealed that the oil recovery would be lower if CO2 concentration is reduced but the extent of oil recovery reduction would be much less than the level of reduction in CO2 concentration.

The unique and integrated research approach employed here enables us to produce a more complete and reliable set of findings and understandings at realistic reservoir conditions. During CWI under reservoir conditions, an "in-situ WAG-type" three-phase flow would be generated with more effective sweep efficiency and pore-scale advantages.

Os atletas foram divididos em dois grupos, sendo o grupo de estudo constituído de 14 atletas arremessadores e o grupo controle de 26 atletas não arremessadores. A força muscular destes atletas foi avaliada por meio de dinamometria isométrica de mola, em duas posições (abdução à 90 graus e posição neutra) tanto para o ato de arremesso quanto para outros gestos decorrentes da prática deste esporte. O objetivo deste estudo foi o de estabelecer possível relação do desequilíbrio da força muscular dos musculos rotadores mediais e laterais durante o arremesso e correlacionar a instabilidade da articulação glenumeral quanto ao lado dominante e não dominante do atleta. Os resultados mostraram uma diferença estatisticamente significante na avaliação do desequilíbrio da força muscular em posição neutra e abdução à 90 graus no lado não dominante .
Contraponto Gramsci-Saïd
Authors: Baratta Giorgio
Published: June 2017

Antonio Gramsci e Edward Saïd, expressões das lutas para arrebatar às classes dominantes a hegemonia, são tomados nesta análise como intelectuais/obras a partir das quais se compreende a dinâmica da construção da democracia progressiva. Ao contrário do que pensam as classes dominantes, exercer hegemonia exige articulações das diferenças e dos conflitos em termos essencialmente políticos e culturais. A concepção gramsciana de hegemonia é assimilada por Saïd como contraponto – ideia-força que apresenta a tentativa de fazer dialogar, interagir, fundir a luta política e a luta militar (em foco a Palestina), com a luta ideológica pela conciliação civil, religiosa, cultural – o humanismo da convivência. Palavras-chave: hegemonia; construção da democracia progressiva; contraponto Gramsci-Saïd.

Introduction: Various skin diseases such as psoriasis, lichen planus, and alopecia areata can be associated with structural nail lesions. However nail lesions prevalence in patients with severe acne vulgaris is not determined. This study aimed to determine the frequency and types of nail lesions in patients with severe acne vulgaris.Methods: In this cross-sectional study, 235 patients with severe acne vulgaris were included from the clinic of dermatology of RasoulAkram Hospital during the years 2010 and 2011. The patients had no history of treatment for acne vulgaris. Patients initially underwent clinical examination, and severity of acne was determined among them. Demographic characteristics such as gender, age, and blood type, and Nail disorders including brittleness, Onycholysis, and Leukonychia were investigated in these patients. Data were analyzed using SPSS 18 software.Results:In this study79 patients with severe acne vulgaris (33.6%) had nail involvement and the frequency of nail lesions in this study was as follows: brittle nails 26.8% (63 cases); Leukonychia 18.2% (43 cases); Parrot beaked nails 3.4% (8 cases) and Onycholysis 1.3% (3 cases). Nail disorders in patients with severe acne vulgaris was not associated with sex, blood group, and the severity and distribution of acne lesions. But the lower age of the patients was associated with the incidence of nail disorders.Conclusion: According to high prevalence of nail involvement, especially brittle nails in patients with severe acne vulgaris, investigation and treatment of nail disorders in these patients have a great importance.

This study was conducted to determine the demographic, clinical, and beyond clinical characteristics in patients with multiple sclerosis to help identify common disabilities and better understand of the specific needs of these ones.Materials and methods: This descriptive cross-sectional study was carried out on 50 MS patients in Rafsanjan, Iran. A definitive diagnosis has been done according to neurologist and McDonald criteria. The neurologist conducted examinations. The demographic data were recorded using questionnaire. MRI images were analyzed with the help of radiologist and all data were analyzed using SPSS software.Results: The mean age was 33.81±8.38 years and male/female ratio was 7/42. According to data, 66.7% of the patients were suffering from relapsing-remitting type (RR) disease, and most lesions on MRI in these patients were observed in pyramidal and JuxtaCortical areas. The mean EDSS scores of patients was 1.46. The duration of disease and the number of attacks had a significant correlation with educational level (P<0.05); age was significantly associated with pyramidal, mental and sphincter symptoms (P<0.05).Conclusion: These results suggest that the prevalence of MS in women is higher than in men, especially among housekeeper women. Relapsing and remitting disease showed higher frequency.
Algunas consideraciones sobre las relaciones intrafamiliares y las redes de apoyo en la China actual
Authors: Botton Beja Flora
Published: June 2017

Estudiar las relaciones intrafamiliares y las redes de apoyo en la China actual nos da la clave para evaluar los cambios en una sociedad históricamente dominada por estas relaciones. La familia tradicional china, base de su sociedad, empezó a sufrir transformaciones radicales a partir de 1949, cuando los comunistas llegaron al poder. Las Leyes de Matrimonio de 1950 y 1980 transfieren prerrogativas del sistema patriarcal dándole al Estado el control. Hasta fines de la década de 1980, la estructura de la sociedad y la familia en China no se había transformado mucho más allá de los patrones que habían fijado los cambios en la economía y la legislación, aunque las actitudes respecto al matrimonio y la situación familiar cambiaban: en un estudio que la autora llevó a cabo en 1987 en seis ciudades chinas se reflejaban estas nuevas actitudes. Pero los cambios más significativos han ocurrido en las últimas décadas, los cuales han permitido mayor equidad de género, libertad para elegir a la pareja y menos urgencia para tener hijos. Estas nuevas realidades, aunadas a las transformaciones económicas y la apertura política, llevaron al gobierno a proceder a una revisión de la Ley de Matrimonio de 1980. La ley revisada, del año 2000, considera situaciones más complejas en las relaciones intrafamiliares y es un esfuerzo tanto para adaptarse a las transformaciones de la familia como para afianzar valores tradicionales. A pesar de que la investigación sobre la familia en China ha estado limitada por las circunstancias políticas, las tendencias se han acentuado con la mayor apertura del país. Así, con base en diversos estudios y encuestas, se examinan relaciones familiares y redes de apoyo a partir de la década de 1990. En la actualidad, las redes de apoyo descansan en un sistema de relaciones interpersonales que se conoce como guanxi: relaciones de intercambio entre iguales. Estas relaciones son importantes para la vida diaria; facilitan el intercambio de servicios y resuelven problemas de vivienda, urbanización, autoempleo, migración y salud. La familia china está cambiando, tanto en el ámbito urbano como en el rural; sin embargo, sigue siendo la principal fuente de apoyo emocional y económico para los individuos.

ESTUDOS SOBRE O PROCESSO DE DESVALORIZAÇÃO DO TRABALHO HUMANO DE ACORDO COM A LÓGICA EMPRESARIAL DO SÉCULO XXI
Authors: Oliveira Lourival José de
Published: June 2017

Do estudo feito, concluiu-se que os avanços tecnológicos impuseram ao homem uma nova rotina de trabalho, mais intensa, reduzindo em demasia a possibilidade de existência de um tempo livre. A tendência é a geração de um trabalho fragmentado, precário, voltado somente à sobrevivência humana, encontrando-se em desacordo com os princípios constitucionais e por sua vez com os direitos sociais, que preveem um trabalho que possa contribuir com a redução das desigualdades sociais, com a emancipação do homem, enquanto dando-lhe condições de expor sua criatividade e de localizar-se no meio social como agente realizador. A expressão trabalho livre toma nova dimensão, enquanto sendo aquele trabalho que, contrariando a lógica do mercado, é suficiente para proporcionar ao ser trabalhador não somente a sobrevivência ou a existência precária, mas uma vida construtiva. A crítica à lógica da produção deve ser capaz de criar mecanismos de intervenção capazes de restabelecer a dignidade no trabalho.

A tutela jurisdicional a garantir maior eficácia ao processo passa pela ampla possibilidade de participação das partes na construção do procedimento e da convicção do julgador. Com essa premissa, as partes podem estabelecer convenções a respeito de seus ônus, poderes, faculdades e deveres processuais, tornando flexível o processo, e favorecendo a construção da melhor tutela ao caso concreto. A Lei nº 13.105/2015 (CPC/2015) colabora, significativamente com a construção do modelo colaborativo de processo civil, e amplifica a abrangência dos negócios jurídicos processuais no âmbito do processo civil brasileiro. Há possibilidade de correlacionar de forma ilustrativa esse fenômeno processual com o direito processual romano, que na fase in iure nos períodos da legis actiones e per formulas atribuía às partes ampla possibilidade de negociação sobre os limites do processo, que seria registrado na litiscontestatio.
LA REPRESENTACIÓN DEL PODER EN LAS COMUNIDADES PROTOHISTÓRICAS DEL NOROESTE PENINSULAR. EXCELENCIA MASCULINA Y COTIDIANIDAD FEMENINA
Authors: González Santana Mónica
Published: June 2017

Resumen: Dentro de las estrategias de acceso al poder de las élites masculinas, la articulación y dominio de los espacios de representación servirían de garantía tanto a la legitimación como a la consolidación de las desigualdades sociales. Una garantía que se apoyaba en el control de las armas, los rituales y la autoridad. En ese sentido, el estudio, como parte del lenguaje simbólico del poder, de los espacios y materiales rescatados nos ayuda a entender cómo se construyeron las diferencias de género y con ellas las desigualdades entre hombres y mujeres.Palabras clave: protohistoria, arqueología, espacios, género, poder, patriarcado, excelencia y cotidianidad.English Title: The Representation of Power in the Northwest Peninsular Protohistoric Communities. Masculine Excellence and Feminine CotidianityAbstract: In the power strategies of masculine elites, the articulation and domination of representational spaces would serve to guarantee their legitimacy, but they would also consolidate social inequalities. Masculine power, shored up by development of defensive weaponry, was organised through control of weapons, rules and rituals. This study of spaces and materials will assist in understanding how such societies, through this symbolic language of power, constructed gender differences and thereby created inequalities between men and women.Key words: protohistory, archaeology, spaces, gender, poser, patriarchy, excellence andcotidianity.

Anime adaptando (y complementando) alta literatura. El sufrimiento de “La dama de la sexta avenida”
Authors: Míguez Santa Cruz Antonio
Published: June 2017

Resumen: Aunque sea paulatinamente, la animación japonesa se está despojando de su connotación negativa. Autores como Hayao Miyazaki han elevado el Anime por encima de muchos perjuicios, y algunas de sus obras incluso consiguen alcanzar una profundidad psicológica y artística más allá de las películas “live”. Este es el caso de Gisaburo Sugii y Osamu Dezaki, dos autores que, adaptando el Genji Monogatari respectivamente, completan la visión de un personaje vital para comprender tanto lo fantasmático como el papel de la mujer en la cultura japonesa: Rokujō no Miyasudokoro.Anime Adapting (and Complementing) High Literature. The Suffering of “The Lady from the Sixth Avenue” Abstract: Japanese animation, although gradually, divests itself of its negative connotation. Authors like Hayao Miyazaki have upgraded Anime beyond many prejudices, and some of their works even achieve a psychological and artistic profundity aside from “live” films/movies. This is the case of Gisaburo Sugii and Osamu Dezaki, two authors that, adapting Genji Monogatari respectively, have achieved a broad and complete vision of a vital character to understand the ghostly thing in Japanese culture: Rokujō no Miyasudokoro.
A scuola di pari opportunità. Il sistema scolastico: un circuito decisivo -ma trascurato- per educare al rispetto dell’identità e della differenza di genere
Authors: Musi Elisabetta
Published: June 2017

Riassunto: La scuola può promuovere un profondo rinnovamento culturale, rivolgendosi a intere generazioni di bambini e bambine, ragazzi e ragazze e alle loro famiglie. E tuttavia, a fronte di un diffuso bisogno di superamento di modelli dominanti nell’ordine simbolico e nell’organizzazione sociale, evidenziati dalle disarmonie in famiglia, dalle tensioni che sfociano in violenze, dalle vessazioni e dalle iniquità sul lavoro, le politiche di un’istruzione attenta ai generi e di promozione di una cultura non discriminante non ricevono l’attenzione che meritano. Nell’argomentare queste posizioni, l’intervento riepiloga per sommi capi l’orientamento delle politiche italiane e del nord Europa in relazione al binomio educazione scolastica e differenza di genere. Al contempo tenta di problematizzare alcune condizioni imprescindibili perché l’attenzione al genere possa promuovere un percorso di civiltà, di maturità e responsabilizzazione di un Paese. An Equal Opportunities School. The School System: A Decisive Circuit –But Neglected– to Educate to Respect the Difference and Gender Identity Abstract: School can foster a deep cultural renewal by addressing whole generations of children and teenagers, along with their families. However, despite a widespread need to overcome prevailing patterns in symbolic order and social organization, revealed by lack of harmony at home, tensions resulting in violence, harassment and iniquities in the workplace… education policies and objectives aimed at teaching about gender citizenship and fostering nondiscrimination culture do not get the deserved attention. By sustaining these positions, the present paper summarizes the stance of Italian and northern European policies with regard to the binomial school education and gender difference. Meanwhile, the article tries to problematize some unavoidable conditions for attention on gender to foster a path of civilization, maturity and assumption of responsibilities on the part of a country.

In this review, the authors describe the available flow diverters, both endoluminal and intrasaccular, addressing nuances of device design and function and presenting data on complications and outcomes, where available. They also discuss possible future directions of flow diversion.
Complications associated with the use of flow-diverting devices for cerebral aneurysms: a systematic review and meta-analysis
Authors: Zhou Geng , Su Ming , Yin Yan-Ling , Li Ming-Hua
Published: June 2017

OBJECTIVE

The objective of this study was to review the literature on the use of flow-diverting devices (FDDs) to treat intracranial aneurysms (IAs) and to investigate the safety and complications related to FDD treatment for IAs by performing a meta-analysis of published studies.

METHODS

A systematic electronic database search was conducted using the Springer, EBSCO, PubMed, Medline, and Cochrane databases on all accessible articles published up to January 2016, with no restriction on the publication year. Abstracts, full-text manuscripts, and the reference lists of retrieved articles were analyzed. Random-effects meta-analysis was used to pool the complication rates across studies.

RESULTS

Sixty studies were included, which involved retrospectively collected data on 3125 patients. The use of FDDs was associated with an overall complication rate of 17.0% (95% confidence interval [CI] 13.6%–20.5%) and a low mortality rate of 2.8% (95% CI 1.2%–4.4%). The neurological morbidity rate was 4.5% (95% CI 3.2%–5.8%). No significant difference in the complication or mortality rate was observed between 2 commonly used devices (the Pipeline embolization device and the Silk flow-diverter device). A significantly higher overall complication rate was found in the case of ruptured IAs than in unruptured IA (odds ratio 2.3, 95% CI 1.2–4.3).

CONCLUSIONS

The use of FDDs in the treatment of IAs yielded satisfactory results with regard to complications and the mortality rate. The risk of complications should be considered when deciding on treatment with FDDs. Further studies on the mechanism underlying the occurrence of adverse events are required.
Vision outcomes in patients with paraclinoid aneurysms treated with clipping, coiling, or flow diversion: a systematic review and meta-analysis
Authors: Silva Michael A. , See Alfred P. , Dasenbrock Hormuzdiyar H. , Patel Nirav J. , Aziz-Sultan Mohammad A.
Published: June 2017

OBJECTIVE

Patients with paraclinoid aneurysms commonly present with visual impairment. They have traditionally been treated with clipping or coiling, but flow diversion (FD) has recently been introduced as an alternative treatment modality. Although there is still initial aneurysm thrombosis, FD is hypothesized to reduce mass effect, which may decompress the optic nerve when treating patients with visually symptomatic paraclinoid aneurysms. The authors performed a meta-analysis to compare vision outcomes following clipping, coiling, or FD of paraclinoid aneurysms in patients who presented with visual impairment.

METHODS

A systematic literature review was performed using the PubMed and Web of Science databases. Studies published in English between 1980 and 2016 were included if they reported preoperative and postoperative visual function in at least 5 patients with visually symptomatic paraclinoid aneurysms (cavernous segment through ophthalmic segment) treated with clipping, coiling, or FD. Neuroophthalmological assessment was used when reported, but subjective patient reports or objective visual examination findings were also acceptable.

RESULTS

Thirty-nine studies that included a total of 2458 patients (520 of whom presented with visual symptoms) met the inclusion criteria, including 307 visually symptomatic cases treated with clipping (mean follow-up 26 months), 149 treated with coiling (mean follow-up 17 months), and 64 treated with FD (mean follow-up 11 months). Postoperative vision in these patients was classified as improved, unchanged, or worsened compared with preoperative vision. A pooled analysis showed preoperative visual symptoms in 38% (95% CI 28%–50%) of patients with paraclinoid aneurysms. The authors found that vision improved in 58% (95% CI 48%–68%) of patients after clipping, 49% (95% CI 38%–59%) after coiling, and 71% (95% CI 55%–84%) after FD. Vision worsened in 11% (95% CI 7%–17%) of patients after clipping, 9% (95% CI 2%–18%) after coiling, and 5% (95% CI 0%–20%) after FD. New visual deficits were found in patients with intact baseline vision at a rate of 1% (95% CI 0%–3%) for clipping, 0% (95% CI 0%–2%) for coiling, and 0% (95% CI 0%–2%) for FD.

CONCLUSIONS

To the authors’ knowledge, this is the first meta-analysis to assess vision outcomes after treatment for paraclinoid aneurysms. The authors found that 38% of patients with these aneurysms presented with visual impairment. These data also demonstrated a high rate of visual improvement after FD without a significant difference in the rate of worsened vision or iatrogenic visual impairment compared with clipping and coiling. These findings suggest that FD is an effective option for treatment of visually symptomatic paraclinoid aneurysms.
Pipeline embolization device versus coiling for the treatment of large and giant unruptured intracranial aneurysms: a cost-effectiveness analysis
Authors: Wali Arvin R. , Park Charlie C. , Santiago-Dieppa David R. , Vaida Florin , Murphy James D. , Khalessi Alexander A.
Published: June 2017

OBJECTIVE

Rupture of large or giant intracranial aneurysms leads to significant morbidity, mortality, and health care costs. Both coiling and the Pipeline embolization device (PED) have been shown to be safe and clinically effective for the treatment of unruptured large and giant intracranial aneurysms; however, the relative cost-to-outcome ratio is unknown. The authors present the first cost-effectiveness analysis to compare the economic impact of the PED compared with coiling or no treatment for the endovascular management of large or giant intracranial aneurysms.

METHODS

A Markov model was constructed to simulate a 60-year-old woman with a large or giant intracranial aneurysm considering a PED, endovascular coiling, or no treatment in terms of neurological outcome, angiographic outcome, retreatment rates, procedural and rehabilitation costs, and rupture rates. Transition probabilities were derived from prior literature reporting outcomes and costs of PED, coiling, and no treatment for the management of aneurysms. Cost-effectiveness was defined, with the incremental cost-effectiveness ratios (ICERs) defined as difference in costs divided by the difference in quality-adjusted life years (QALYs). The ICERs < $50,000/QALY gained were considered cost-effective. To study parameter uncertainty, 1-way, 2-way, and probabilistic sensitivity analyses were performed.

RESULTS

The base-case model demonstrated lifetime QALYs of 12.72 for patients in the PED cohort, 12.89 for the endovascular coiling cohort, and 9.7 for patients in the no-treatment cohort. Lifetime rehabilitation and treatment costs were $59,837.52 for PED; $79,025.42 for endovascular coiling; and $193,531.29 in the no-treatment cohort. Patients who did not undergo elective treatment were subject to increased rates of aneurysm rupture and high treatment and rehabilitation costs. One-way sensitivity analysis demonstrated that the model was most sensitive to assumptions about the costs and mortality risks for PED and coiling. Probabilistic sampling demonstrated that PED was the cost-effective strategy in 58.4% of iterations, coiling was the cost-effective strategy in 41.4% of iterations, and the no-treatment option was the cost-effective strategy in only 0.2% of iterations.

CONCLUSIONS

The authors’ cost-effective model demonstrated that elective endovascular techniques such as PED and endovascular coiling are cost-effective strategies for improving health outcomes and lifetime quality of life measures in patients with large or giant unruptured intracranial aneurysm.
Near-Graphite Coke Deposit on Nano-HZSM-5 Aggregates for Methanol to Propylene and Butylene Reaction
Authors: Sang Yu , Xing Aihua , Wang Chuanfu , Han Zhihua , Wu Yulong
Published: June 2017

Nanocrystal HZSM-5 zeolite aggregates with different SiO2/Al2O3 molar ratios were prepared under low temperature and were used to catalyze the conversion of methanol to propylene and butene. The coke location, coke content, and coke species deposited on HZSM-5 aggregates were investigated. The near-graphite carbon on the external surface of HZSM-5 zeolite (SiO2/Al2O3 molar ratio = 400) was distinguished by transmission electron microscopy (TEM) and energy dispersive spectrometer (EDS). The carbon distributions in the micropores and on the external surface of the spent HZSM-5 were revealed by thermogravimetric analysis (TGA) and Brunauer-Emmett-Teller (BET) results. Coke preferred to deposit in the mircopores of low SiO2/Al2O3 molar ratio samples (200, 300) with relatively uniform Al distribution, while coke also preferred to deposit on the external surface and in the intergranular spaces of high SiO2/Al2O3 molar ratio sample (400) with an obviously poor Al core and rich Al shell.

Published: June 2017

Nanocrystalline ZnO, ZnO(Ga), and ZnO(Ga, In) samples with different indium contents were prepared by wet-chemical method and characterized in detail by ICP-MS and XRD methods. Gas sensing properties toward NO2 were studied at 150–450 °C by DC conductance measurements. The optimal temperature for gas sensing experiments was determined. The dependence of the ZnO(Ga, In) sensor signal to NO2 at 250 °C correlates with the change of conductivity of the samples. The introduction of indium into the system leads to an increase in the values of the sensor signal in the temperature range T < 250 °C. The investigation of the local sample conductivity by scanning spreading resistance microscopy demonstrates that, at high indium content, the sensor properties are determined by the In–Ga–Zn–O layer that forms on the ZnO surface.
On the Generality of Codebook Approach for Sensor-Based Human Activity Recognition
Authors: Shirahama Kimiaki , Grzegorzek Marcin
Published: June 2017

With the recent spread of mobile devices equipped with different sensors, it is possible to continuously recognise and monitor activities in daily life. This sensor-based human activity recognition is formulated as sequence classification to categorise sequences of sensor values into appropriate activity classes. One crucial problem is how to model features that can precisely represent characteristics of each sequence and lead to accurate recognition. It is laborious and/or difficult to hand-craft such features based on prior knowledge and manual investigation about sensor data. To overcome this, we focus on a feature learning approach that extracts useful features from a large amount of data. In particular, we adopt a simple but effective one, called codebook approach, which groups numerous subsequences collected from sequences into clusters. Each cluster centre is called a codeword and represents a statistically distinctive subsequence. Then, a sequence is encoded as a feature expressing the distribution of codewords. The extensive experiments on different recognition tasks for physical, mental and eye-based activities validate the effectiveness, generality and usability of the codebook approach.
Recent Advances in the Synthesis of Metal Oxide Nanofibers and Their Environmental Remediation Applications
Authors: Mondal Kunal
Published: June 2017

Recently, wastewater treatment by photocatalytic oxidation processes with metal oxide nanomaterials and nanocomposites such as zinc oxide, titanium dioxide, zirconium dioxide, etc. using ultraviolet (UV) and visible light or even solar energy has added massive research importance. This waste removal technique using nanostructured photocatalysts is well known because of its effectiveness in disintegrating and mineralizing the unsafe organic pollutants such as organic pesticides, organohalogens, PAHs (Polycyclic Aromatic Hydrocarbons), surfactants, microorganisms, and other coloring agents in addition to the prospect of utilizing the solar and UV spectrum. The photocatalysts degrade the pollutants using light energy, which creates energetic electron in the metal oxide and thus generates hydroxyl radical, an oxidative mediator that can oxidize completely the organic pollutant in the wastewater. Altering the morphologies of metal oxide photocatalysts in nanoscale can further improve their photodegradation efficiency. Nanoscale features of the photocatalysts promote enhance light absorption and improved photon harvest property by refining the process of charge carrier generation and recombination at the semiconductor surfaces and in that way boost hydroxyl radicals. The literature covering semiconductor nanomaterials and nanocomposite-assisted photocatalysis—and, among those, metal oxide nanofibers—suggest that this is an attractive route for environmental remediation due to their capability of reaching complete mineralization of organic contaminants under mild reaction conditions such as room temperature and ambient atmospheric pressure with greater degradation performance. The main aim of this review is to highlight the most recent published work in the ﬁeld of metal oxide nanofibrous photocatalyst-mediated degradation of organic pollutants and unsafe microorganisms present in wastewater. Finally, the recycling and reuse of photocatalysts for viable wastewater purification has also been conferred here and the latest examples given.
Persecution and the Art of Writing between the Lines: De vita beata, Lactantius, and the Great Persecution
Authors: Digeser Elizabeth Depalma
Published: June 2017

Patristics scholars and historians have tended to ignore Book 7 (De vita beata) of Lactantius’ Divine Institutes, a seeming pastiche of prophecies about the end times, penned between 306 and 310. If it is situated in the broader context of Porphyry of Tyre’s contemporary critique of the Book of Daniel as ex eventu prophecy, however, its diatribes against two ruling “ beasts” point to the emperors Diocletian and Galerius who had launched and pursued the “ Great Persecution” against the Christians. Pressing these parallels further suggests that the “ heavenly king” who will rescue the world and impose sole rule for a new millennium is none other than Constantine, who had gained control of the northwestern empire in 306.
Een verhaal van mensen en structuren. Inter viewen over rurale organisaties
Authors: Bisschop Chantal
Published: June 2017

In mijn onderzoek naar de transformatie van de Boerenbond en de aanpassing van deze oude landbouworganisatie aan een snel veranderende wereld, focuste ik op de wisselwerking tussen structuren en actoren. Het archief-en literatuuronderzoek was vooral geschikt om de evoluerende structuren en dynamiek van de organisatie bloot te leggen. De mondelinge bronnen waren bijzonder interessant voor de betekenisgeving en beleving van de mensen in de organisatie op verschillende niveaus. Ik maakte gebruik van vier groepen van interviews, elk met een eigen doel, transcriptiewijze en analysemethode. De keuze om pas na uitgebreid vooronderzoek met mensen te gaan praten, bood verschillende voordelen in het vlak van analyse en geheugenvorming. De inhoudelijke analyse van een grote groep mondelinge bronnen werd gecombineerd met de intensieve narratieve en performatieve analyse van een klein aantal getuigenissen die poëtisch, in versregels en strofen, werden getranscribeerd. De work story als variant op de life story is bij dergelijke interviews een aan te raden methode. Deze intersubjectiviteit van mondelinge geschiedenis beschouwde ik als een kans en meerwaarde voor dit onderzoek. Daarom reflecteerde ik niet alleen kritisch over de subjectieve positie van de personen die ik interviewde maar ook over mijn eigen inbreng en impact op het onderzoeksproces.
Isobaric Reconstruction of the Baryonic Acoustic Oscillation

Published: June 2017

In this Letter, we report a significant recovery of the linear baryonic acoustic oscillation (BAO) signature by applying the isobaric reconstruction algorithm to the nonlinear matter density field. Assuming only the longitudinal component of the displacement being cosmologically relevant, this algorithm iteratively solves the coordinate transform between the Lagrangian and Eulerian frames without requiring any specific knowledge of the dynamics. For dark matter field, it produces the nonlinear displacement potential with very high fidelity. The reconstruction error at the pixel level is within a few percent and is caused only by the emergence of the transverse component after the shell-crossing. As it circumvents the strongest nonlinearity of the density evolution, the reconstructed field is well described by linear theory and immune from the bulk-flow smearing of the BAO signature. Therefore, this algorithm could significantly improve the measurement accuracy of the sound horizon scale s. For a perfect large-scale structure survey at redshift zero without Poisson or instrumental noise, the fractional error

is reduced by a factor of ∼2.7, very close to the ideal limit with the linear power spectrum and Gaussian covariance matrix.

CO is an important component in many

atmospheres, including Titan, Triton, and Pluto, and has also been detected in the atmosphere of a number of exoplanets. Numerous experimental simulations have been carried out in the laboratory to understand the chemistry in

atmospheres, but very few simulations have included CO in the initial gas mixtures. The effect of CO on the chemistry occurring in these atmospheres is still poorly understood. We have investigated the effect of CO on both gas and solid phase chemistry in a series of planetary atmosphere simulation experiments using gas mixtures of CO,

, and

with a range of CO mixing ratios from 0.05% to 5% at low temperature (∼100 K). We find that CO affects the gas phase chemistry, the density, and the composition of the solids. Specifically, with the increase of CO in the initial gases, there is less

but more

, HCN,

, and

produced in the gas phase, while the density, oxygen content, and degree of unsaturation of the solids increase. The results indicate that CO has an important impact on the chemistry occurring in our experiments and accordingly in planetary atmospheres.
Neorealism and Contemporary US-Russian Military Competition in the Post-Soviet Space
Authors: Eichler Jan
Published: June 2017

In the light of neorealist theory, the Eastern enlargement of NATO satisfies basic feature of expansion: 9 former countries of the Warsaw Pact become members of NATO. USA as a Sea power reinforced its superiority at the detriment of the RF as a continental power. The annexation of Crimea, as a Russian answer, had intensified security fears of post - Soviet countries and of Poland and enlarged the space for external balancing of the USA. Author warns that a confrontational structure had become typical for the area or the Western part of the Post - Soviet space. It increases the number of military incidents, and, even, the threat of a direct military confrontation including a Russian use of tactical nuclear arms, being inspired by the Rogers plan from 1980´s.
Le témoignage de l’esprit chez Hegel
Authors: Marmasse Gilles
Published: June 2017

Si Hegel utilise régulièrement l’expression de « témoignage de l’esprit », celle-ci n’a pourtant pas chez lui un sens spécifiquement théologique. Elle désigne l’activité caractéristique de tout esprit, à savoir la manifestation de soi spontanée et intégrale. L’article examine les formes et les enjeux, mais aussi les limites, d’une telle auto-manifestation dans la philosophie de Hegel.
