Formation and Prevention of Iron-Silicate Scales in Steam Generators, Cymric Field, California
Authors: Daniels E. J. , Frank W. E. , Orton G. S. 
Published: December 2017

Abstract
Water geochemistry and scaling studies were conducted to reduce the formation of silica-based scales within steam generators in the San Joaquin Valley. A combination of laboratory tests and field data have improved understanding of chemical and operational parameters controlling scale formation and helped determine cost-effective solutions for reducing heat management costs in Chevron's Cymric Field steamflood operation.
Silicate scaling problems have been observed within and downstream of steam generators in the Cymric Field, San Joaquin Valley, California, as well as in producer wellhead chokes. The onset of such scaling problems correlated with the initiation of steam-assisted recovery from opal-rich siliceous shale reservoir units in the Cymric operation. The scale is primarily comprised of iron-rich silicates, acmite (NaFe2Si2O6) and vermiculite (Na0.7Fe2Si4O10(OH)2, a swelling clay). Formation of such scales causes (1) pipe erosion in the generator, resulting in steam leaks and increased frequency of generator repairs and downtime and (2) selective plugging of the surface steam distribution system and producer wellhead chokes, which impairs uniform heat distribution across the field.
Formation of these scale minerals has been successfully reproduced in laboratory autoclave experiments run under simulated steam conditions, using Cymric field feedwater and steel coupons. The laboratory results indicate that acmite scale formation requires the availability of iron (e.g., from pipe corrosion/erosion), and a minimum concentration of ~428–510 mg/L of dissolved SiO2(aq), depending on the generator temperature. Such silica concentrations are easily exceeded in steam generator boiler liquid if, for example, the feedwater contains &gt;100 mg/L SiO2(aq) and the generator is operated at &gt;75% steam quality. Formation of acmite scale can be cost-effectively prevented by maintaining a dissolved silica concentration in the boiler liquid that is below this critical threshold concentration. The ultimate silica concentration in the boiler liquid can be manipulated through freshwater dilution of the feedwater, adjustment of the generator steam quality, or silica removal treatments. Alternate silicate scale prevention methods currently under investigation include use of polymeric silicate scale inhibitors in steam generator feedwater.
Unzeitgemäße Betrachtung. Nietzsche et cetera.
Authors: Böhler Arno 
Published: December 2017

Die Lecture-Performance „Unzeitgemäße Betrachtung. Nietzsche et cetera“ wurde bei dem Forschungsfestival Philosophy On Stage#4 am Tanzquartier Wien uraufgeführt, das sich zum Ziel gesetzt hatte, neue Allianzen zwischen Philosophie und den Künsten zu erproben.In dem folgenden Script zur Performance wird die Philosophie als ein Modus des In-der-Zeit-seins verstanden, in der sich Unzeitgemäßes zeigt, indem eine Revolte der Zeit gegen die Zeit zu Gunsten einer kommenden Zeit in Gang gebracht wird. Die Zeitlichkeit des Unzeitgemäßen, die das philosophierende Denken begrifflich freisetzen kann, gehört weder dem Regime der Vergangenheit, noch dem der Ewigkeit an, sie ruft vielmehr Zukunft hervor.Da die Philosophie diese Fähigkeit mit den Künsten teilt, wird kunstbasiertes Philosophieren in der Lecture-Performance als ein Feld gedacht, das Unzeitgemäßes erscheinen lässt. Wobei unter kunstbasiertem Philosophieren jene Allianz der Künste mit der Philosophie verstanden wird, in der die Philosophie künstlerische Forschungspraktiken in die Praktiken des Philosophierens mit einbezieht.In seiner Schrift Politik der Freundschaft hat Jacques Derrida aufgezeigt, dass der Satz „Ach! Wenn ihr wüsstet, wie es bald, so bald schon – anders kommt! …“ das aporetische Prinzip einer Demokratie der Zukunft zur Sprache bringt, in der die Zeitlichkeit des Unzeitgemäßen in Gang gebracht wird. Dabei verweist der Genitiv in der Formulierung Demokratie der Zukunft auf eine Form von Demokratie hin, die nur solange existiert, solange sie sich für ihre eigene Veränderlichkeit und Ereignishaftigkeit offen hält. Eine solche Form von Demokratie wird stets das Vorspiel einer Zukunft gewesen sein, die man vorab mit ganzem Herzen bejahen muss, um ihr Kommen zu ermöglichen; wieder und wieder.Ein Modus der Bejahung des Werdens, der eng mit Nietzsches abgründigstem Gedanken in Verbindung steht – dem Gedanken der ewigen Wiederkehr des Gleichen, in dem die Zeit ihr Werden ewig wieder-holt, um sich als Leben einer immanenten, nicht enden wollenden Bewegung der Unendlichkeit in sich selbst unaufhörlich zu vollziehen.
Combined treatment of hydroxypropyl guar gum in oilfield fracturing wastewater by coagulation and the UV/H2O2/ferrioxalate complexes process
Authors: Zhang Zhenchao 
Published: December 2017

Abstract
Hydroxypropyl guar gum is considered to be a main component of oilfield fracturing wastewater (OFW). This work is intended to optimize the experimental conditions for the maximum oxidative degradation of hydroxypropyl guar gum by the coagulation and UV/H2O2/ferrioxalate complexes process. Optimal reaction conditions were proposed based on the chemical oxygen demand (COD) removal efficiency and UV_vis spectra analysis. The overall removal efficiency of COD reached 83.8% for a dilution ratio of raw wastewater of 1:2, pH of 4 and FeCl3 loading of 1,000 mg/L in the coagulation process; the dosage of H2O2 (30%,v/v) was 0.6% (v/v) and added in three steps, the n(H2O2)/n(Fe2+) was 2:1, n(Fe2+)/n(C2O42−) was 3:1 and pH was 4 in the UV/H2O2/ferrioxalate complexes process; pH was adjusted to 8.5–9 by NaOH and then cationic polyacrylamide (CPAM) of 2 mg/L was added in the neutralization and flocculation process. The decrease in COD during the coagulation process reduced the required H2O2 dosage and improved efficiency in the subsequent UV/H2O2/ferrioxalate complexes process. Furthermore, COD removal efficiency significantly increased by more than 13.4% with the introduction of oxalate compared with UV/Fenton. The UV_vis spectra analysis results indicated that the coagulation and UV/H2O2/ferrioxalate complexes process could efficiently remove the hydroxypropyl guar gum dissolved in OFW. An optimal combination of these parameters produced treated wastewater that met the GB8978-1996 Integrated Wastewater Discharge Standard level III emission standard.

Published: December 2017

Abstract
Anti-fouling copper hydroxide nanowires (CHNs)-graphene oxide (GO) nanocomposites membrane was fabricated by a vacuum-assisted filtration self-assembly process. CHNs were covered on the surface and inserted into the interlayers of the GO nanosheets to form the rough surface and nanostructure channels. The membrane with water contact angles (CAs) of 53° and oil CAs of 155° exhibited superior stability, hydrophilicity, underwater superoleophobicity and ultralow oil adhesion, and hence it could separate the oil-water emulsion with a high efficiency of &gt;99%. This membrane showed the combined advantages of high oil rejection rate and ultralow membrane fouling, making it promising for practical oil-water emulsion separation applications.

Authors: Kamal Mustofa , Santosa Riyadi , Djatmika Djatmika 
Published: December 2017

ABSTRACTThis research investigates how journalists behave in texts. The analysis focuses on the exploitation of attitudinal lexis. This is qualitatively explored through attitude and graduation. The data sources were columns of news, taken from an online version of The Jakarta Post on June sixth 2016. Having been selected using criterion-based sampling technique, the sources of data resulted in six chemical castration texts. The procedure of investigation consists of domain, taxonomic, componential, and cultural value analysis. The result shows that journalists are relatively subjective in reporting news by unbalancing the pros and cons, relatively inconsistent in work from delivering news to criticizing government officials, and relatively provocative by up-scaling critical evaluations against the government policy on sex offenders. Keywords: attitude, graduation, chemical castration, journalists, evaluations
The Intricacy of Policy Analysis: A Book Review
Authors: Djindan Muhammad 
Published: December 2017

Much has been written about mining projects and the contestation of these project development in the literature. The different perspectives that are employed to analyze this issue to some extent are enriching the academic debates but at the same time also increases the difficulty of understanding the problem. As a result, navigating the overall academic discussion in the subject matter is not an easy task. Instead of outlining the overall landscape of mining contestation in the literature, choosing a particular approach and being consistent with this choice is a strategic decision that may result in a high-quality academic work. Following this recipe, Ardianto chose the constructivist approach by employing Laclau and Mouffe’s discourse analysis to understand the mining project contestation in Rembang, Central Java, Indonesia. This paper aims to review a book by Ardianto, entitled "Mitos Tambang untuk Kesejahteraan: Pertarungan Wacana Kesejahteraan dalam Kebijakan Pertambangan" (The Myth of Mining for Welfare: The Welfare Discourses Struggle in Mining Policy).

Tutkimuksen tarkoituksena oli vertailla vuosina 1920 (n = 1032) ja 1940 (n = 956) syntyneiden 70-vuotiaiden kotona asuvien turkulaisten koettua terveyttä, elintapoja ja fyysistä toimintakykyä. Tiedot koetusta terveydestä, elintavoista (tupakointi, alkoholinkäyttö ja painoindeksi) ja fyysisestä toimintakyvystä (päivittäiset toiminnot, välineelliset toiminnot ja päivittäisiä toimintoja haittaavat oireet) kerättiin kyselylomakkeiden ja haastatteluiden avulla. Tulosten mukaan vuonna 1940 syntyneet kokivat terveytensä ja fyysisen toimintakykynsä paremmiksi kuin vuonna 1920 syntyneet. Lisäksi 1940 syntyneillä oli vähemmän päivittäistä toimintaa haittaavia oireita kuin vuonna 1920 syntyneillä. Alkoholin käyttö ja ylipaino sen sijaan olivat yleisempiä 1940 syntyneiden kuin 1920 syntyneiden keskuudessa. Tulokset ovat tärkeitä suunniteltaessa ennaltaehkäiseviä palveluita ikääntyville.
Self-perceived health, health behaviour and physical functioning – a comparison of two cohorts born in 1920 and 1940
The aim of the study was to compare differences in self-perceived health, health behaviour and physical functioning between community-dwelling 70-year-old citizens of Turku born in 1920 (n=1032) and 1940 (n=956). Data of self-perceived health, health behaviour (smoking, alcohol consumption, body mass index) and physical functioning (activities of daily living, instrumental activities of daily living, symptoms causing difficulties in daily living) were collected using questionnaires and interviews. According to the results, self-perceived health and physical functioning were better among those born in 1940 than among those born in 1920. In addition, symptoms causing difficulties in daily living were less frequent in 1940 cohort than in 1920 cohort. However, alcohol consumption and overweight were more common in 1940 cohort compared to 1920 cohort. These results are applicable in planning of preventive services for older people.

Abstract
The unprecedented depth and area surveyed by the Subaru Strategic Program with the Hyper Suprime-Cam (HSC-SSP) have enabled us to construct and publish the largest distant cluster sample out to

to date. In this exploratory study of cluster galaxy evolution from z = 1 to z = 0.3, we investigate the stellar mass assembly history of brightest cluster galaxies (BCGs), the evolution of stellar mass and luminosity distributions, the stellar mass surface density profile, as well as the population of radio galaxies. Our analysis is the first high-redshift application of the top N richest cluster selection, which is shown to allow us to trace the cluster galaxy evolution faithfully. Over the 230 deg2 area of the current HSC-SSP footprint, selecting the top 100 clusters in each of the four redshift bins allows us to observe the buildup of galaxy population in descendants of clusters whose

mass is about

. Our stellar mass is derived from a machine-learning algorithm, which is found to be unbiased and accurate with respect to the COSMOS data. We find very mild stellar mass growth in BCGs (about 35% between z = 1 and 0.3), and no evidence for evolution in both the total stellar mass–cluster mass correlation and the shape of the stellar mass surface density profile. We also present the first measurement of the radio luminosity distribution in clusters out to

The Evolution of the Type Ia Supernova Luminosity Function
Authors: Shen Ken J. , Toonen Silvia , Graur Or 
Published: December 2017

Abstract
Type Ia supernovae (SNe Ia) exhibit a wide diversity of peak luminosities and light curve shapes: the faintest SNe Ia are 10 times less luminous and evolve more rapidly than the brightest SNe Ia. Their differing characteristics also extend to their stellar age distributions, with fainter SNe Ia preferentially occurring in old stellar populations and vice versa. In this Letter, we quantify this SN Ia luminosity–stellar age connection using data from the Lick Observatory Supernova Search (LOSS). Our binary population synthesis calculations agree qualitatively with the observed trend in the

old populations probed by LOSS if the majority of SNe Ia arise from prompt detonations of sub-Chandrasekhar-mass white dwarfs (WDs) in double WD systems. Under appropriate assumptions, we show that double WD systems with less massive primaries, which yield fainter SNe Ia, interact and explode at older ages than those with more massive primaries. We find that prompt detonations in double WD systems are capable of reproducing the observed evolution of the SN Ia luminosity function, a constraint that any SN Ia progenitor scenario must confront.

Published: December 2017

Nos anos 1930, a ideia do atraso no Brasil esteve condicionada pelo mimetismo cultural, e a saída proposta pelas escolas Nacionalista, Católica e Escola Nova foi o projeto de educação como suporte para formação do ethos nacional por intermédio da cultura. A disputa de ideias entre os projetos de educação destas escolas reverberou do campo simbólico para o institucional, pela normatização do projeto de educação no Ministério da Educação e Saúde, do governo Vargas. O objetivo deste artigo atende a dois movimentos: o primeiro buscar compreender o diagnóstico do atraso e prognóstico dele por intermédio da interpretação de Fernando de Azevedo, pela análise das suas obras A Cultura Brasileira e Novos Caminhos e Novos Fins; o segundo movimento, em que medida o Ministério Capanema adotou diretrizes apontadas nos três projetos em disputa para a formulação do Plano Nacional da Educação
