Published: June 2018

Abstract
Selection of effective corrosion for use in high wall shear conditions is of increasing importance in oilfield production. Development of new oil and gas fields often requires the use of more sophisticated downhole equipment. As a result these production conditions can result in exceptionally high wall shear stress, for example in-flow control devices (ICDs) can reach shear stresses up to 10,000 Pa. To accommodate this, there is need for more representative high shear tests for material and production chemical selection. A jet impingement test procedure is shown that allows for the evaluation of products under such environments. Further to this the shear stresses generated in standard laboratory tests have been compared with a high flow pilot rig and comparative Computational Fluid Dynamics (CFD) modelling.
A test system has been developed that allows routine laboratory evaluation of corrosion processes at moderate to high shear stresses using jet impingement methodology. A series of tests have been conducted to determine the extent of corrosion under moderate to high shear conditions. Static tests and low shear rotating cylinder electrode (RCE) tests have been carried out using the same brine system to allow comparison of results from the different methods. Ultimately, high flow (moderate to high shear) pilot rig tests have also been used to verify the results.
The results show that the jet impingement approach is effective in generating field representative conditions, which in turn can support material or chemical selection. The work presented is supported by case studies which will be illustrated.
In order to test effectively, the flow regimes experienced in the field must be replicated. Using CFD models we demonstrate that the observed field conditions can be reproduced using these laboratory flow regimes and produce results that correlate well.
Seasonal streamflow forecasts using mixture-kernel GPR and advanced methods of input variable selection

Published: June 2018

AbstractGaussian Process Regression (GPR) is a new machine-learning method based on Bayesian theory and statistical learning theory. It provides a flexible framework for probabilistic regression and uncertainty estimation. The main effort in GPR modelling is determining the structure of the kernel function. As streamflow is composed of trend, period and random components. In this study, we constructed a mixture-kernel composed of squared exponential kernel, periodic kernel and a rational quadratic term to reflect different properties of streamflow time series to make streamflow forecasts. A relevant feature-selection wrapper algorithm was used, with a top-down search for relevant features by Random Forest, to offer a systematic factors analysis that can potentially affect basin streamflow predictability. Streamflow prediction is evaluated by putting emphasis on the degree of coincidence, the deviation on low flows, high flows and the error level. The objective of this study is to construct a seasonal streamflow forecasts model using mixture-kernel GPR and the advanced input variable selection method. Results show that the mixture-kernel GPR has good forecasting quality, and top importance predictors are streamflow at 12, 6, 5, 1, 11, 7, 8, 4 months ahead, Nino 1 + 2 at 11, 5, 12, 10 months ahead.

Published: June 2018

AbstractAddition of ferrous and ferric iron salts to wastewater is a commonly used practice for sulfide abatement in sewer force mains. When iron is added to wastewater where sulfate respiration takes place, it produces ferrous sulfide precipitates with the formed sulfide. The effect of iron addition has traditionally been focused on solely from the perspective of reaction stoichiometry. Possible influences on the microbial communities in biofilms growing in force mains have largely been neglected. In this study the activity and microbiome was examined in three pilot scale force mains conveying real wastewater, two subjected to iron treatment and one operated as an untreated control. Activity was measured on suspended biofilm samples extracted from the experimental setup. The microbiome of the biofilm was analyzed by V3 + V4 16S rDNA sequencing. Correlation analysis of chemical composition of the biofilms and activity measurements for operational taxonomic units of relevance to sulfide and methane production were performed. In conclusion, it was found that both ferrous and ferric treatment reduced sulfate reduction and methane production, and that both iron salts induced significant changes to force main biofilm microbiomes.

Published: June 2018

Background:
All over the world, the quality of commercial honeys varies greatly depending
on many factors. Hence, this study was conducted to evaluate the physicochemical and antioxidant
properties of Iranian commercial honeys to confirm their nutritional and economical quality.

Methods:
Fifty three honey samples from six different types, including alfalfa, milkvetch, lotus,
thyme, coriander and multifloral honeys, were analyzed for pH, free acidity, electrical conductivity,
Ash, moisture, hydroxymethylfurfural, reducing sugars, glucose, fructose, proline, color, total phenolic
content, ferric reducing antioxidant power and DPPH radical-scavenging activity.

Results:
: In total, physicochemical properties of different honey types were in the range of 4.3 ± 0.49
to 5.2 ± 0.49 for pH, 13.81 ± 2.5 to 26.22 ± 2.8 for free acidity (meq/kg), 15.95 ± 0.45 to 17.98 ± 0.97
for moisture (%), 282.2 ± 50.3 to 578 ± 47 for electrical conductivity (µS/cm), 0.14 ± 0.04 to 0.38 ±
0.03 for ash (g/100 g), 68.66 ± 4.3 to 72.09 ± 6.4 for reducing sugars (g/100 g), 34.67 ± 2.6 to 36.7 ±
2.2 for glucose (g/100 g), 31.9 ± 4.75 to 37.04 ± 4.0 for fructose (g/100 g), 6.1 ± 5.8 to 22.85 ± 10.9
for hydroxymethylfurfural (mg/kg), 426.7 ± 53.91 to 593.9 ± 108.6 for proline (mg/kg), 46.27 ± 4.3 to
96.04 ± 14.4 for color (mm) and 245.4 ± 48.45 to 573.9 ± 69.3 for total phenolic (mg/kg) content. In
terms of antioxidant capacity, lotus and thyme honeys were preferable, while the highest level of
DPPH radical scavenging activity and ferric reducing antioxidant power were observed in lotus and
thyme honeys.

Conclusion:
These results confirmed that the Iranian commercial honeys meet the quality standards
established by national and international regulatory agencies.
On the Use of 6th-Order Tunable Complementary Metal-Oxide-Semiconductor Varactor based Filter in Ultra-Wideband Low Noise Amplifier
Authors: Khaleel Farooq , Nadhim Abbas M. 
Published: June 2018

Background:The plethora of the emerged radio frequency applications makes the frequency spectrum crowded by many applications and hence the ability to detect specific application’s frequency without distortion is a difficult task to achieve.Objective:The goal is to achieve a method to mitigate the highest interferer power in the frequency spectrum in order to eliminate the distortion.Method:This paper presents the application of the proposed tunable 6th-order notch filter on Ultra-Wideband (UWB) Complementary Metal-Oxide-Semiconductor (CMOS) Low Noise Amplifier (LNA) utilising self-forward body bias (SFBB).Results:The proposed filter presents 23.5dBm minimum interferer rejection (IR) and attenuates the interferer signal from -43dBm to -67dBm at frequency 5.17GHz. In addition, the maximum IR is 40dBm and attenuates the interferer signal from -41dBm to -81dBm at frequency 5.785GHz. The proposed filter provides coarse tuning with frequency spacing (10MHz) and soft tuning with frequency spacing (1MHz). The UWB CMOS LNA consumes only 5.22mW from a supply voltage of 1.2V and presents a maximum gain of 14dB at frequency 6.25GHz in the -3dB bandwidth from 4.75GHz to 7.5GHz. In addition, the average noise figure is 3.1dB and the input insertion losses (S11) is less than -12dB along the designed bandwidth. The simulation is performed in Advanced Design System (ADS2016.01) software utilising 180nm Taiwan Semiconductor Manufacturing Company (TSMC) Berkeley Short-channel Insulated Gate Field Effect Model (BSIM3v3) model files.Conclusion:The proposed method achieves high interferer power rejection with both soft and coarse tuning.

Authors: Pockpa Ange Désiré , Soueidan Assem , Louis Pauline , Coulibaly Nadin Thérèse , Badran Zahi , Struillou Xavier 
Published: June 2018

Background:
Conventional periodontal treatment, performed quadrant by quadrant in multiple visits, was re-evaluated in the early 1990s when the full-mouth disinfection concept was introduced. Over the years, several modifications to the full-mouth disinfection approach have been suggested.

Objective:
The purpose of this article is to review the evolution of full-mouth disinfection during the past 20 years, to specify its indications and to consider the prospects for this approach.

Materials and Methods:
An electronic and manual search of the literature, ending in December 2016, was performed by two independent researchers. Only pivotal studies and randomized controlled clinical trials published in the English language that evaluated a new approach to full-mouth disinfection were selected.

Results:
According to the studies included in our analysis (21 articles), several modified full-mouth disinfection protocols have been designed including: full-mouth treatment without chlorhexidine, the extension of hygiene methods and an increase in the duration of post-treatment chlorhexidine use, the replacement of chlorhexidine with other antiseptics, supplementation with antibiotics or probiotics, full-mouth antimicrobial photodynamic therapy and one-stage full-mouth disinfection combined with a periodontal dressing.

Conclusion:
Since 1995, several modifications have been suggested to improve the effectiveness of full-mouth disinfection. The majority of the studies demonstrate that the results obtained with full-mouth disinfection and its variants are equivalent to each other and to those obtained with the conventional quadrant method. Currently, the selection of this technique remains empirical and depends on the preferences of the practitioner and the patient. In the future, a patient-centered approach should be the best indication for the use of this technique.

<p>In recent years, we have heard and seen many economic activities based on Islamic law or Sharia law. These activities are related to the production process in the service industry. So it appears Sharia Business Unit (UUS), such as Islamic Banking, Sharia Insurance, Sharia Pawnshops, Sharia Leasing, even up to syariah tourism. This is certainly very reasonable, because the rationality and social level of human life undergo many changes, from the level of social and economic life that has freedom, to a new economic level that requires religious values. The Islamic economic system has different characteristics from conventional economics. Islamic economics is a fair and thorough system and seeks to ensure that wealth is not collected only to one group, but spread throughout society. (Afzalur Rahman, 1996: 11). One of Sharia financial institutions that can apply the sharia principles is Sharia Insurance. This research will try to analyze the principles of sharia in insurance, using qualitative descriptive method that is describing the object of research by using literature study that comes from the relevant book or journal. The result of the research shows that there are 8 principles in Takaful Insurance which become the guideline of implementation, that is Tawheed (Ketaqwaan), Justice, Not Dzalim, At Tawaun (please help), Amanah, Ridha, Khitmah (good service), and free from gharar element, maisir, and usury. In practice many sharia entities have been implementing sharia principles well although there are still some shortcomings in Takaful insurance, for example in research that has been done by Erza Armas hardi, 2015 obtained the result that Takaful insurance has not touched the bottom of society group (grass root).</p><p>Keywords : Sharia Insurance, Sharia Principles, Sharia Entity, Tabarru</p>

The time of money in finance and US society
Authors: Esposito Elena 
Published: June 2018

AbstractTraditional societies were defined by a prevalence of the past in the definition of the present. United States (US) society seems to show the opposite trend: the present is defined as the preparation of the future. Financial temporality can be seen as an example of the present use of the future, transforming future possibilities into available wealth. As the financial crisis has shown, however, the temporality of the future is more complex and circular. This article deals with quantitative easing (QE) as a financial instrument with an essentially temporal nature (in the sense that it uses time and acts on the future and on expectations). The success of QE in the US economy reveals essential aspects of US temporality, but also raises questions as to how it may differ from European temporality. The analysis of QE measures and their impact also offers ways to assess whether and by which means politics can intervene into finance, as well as what consequences and uncertainties are created in the process.
Transforming usury into finance: Financialization and the ethics of debt
Authors: Walsh Kate Padgett 
Published: June 2018

AbstractThis article examines the conceptual transformation of what was once considered usury into finance. To counter traditional arguments that usury was exploitative and unnatural, early modern theorists reconceptualized debt as a form of investment for both borrowers and lenders. Today, this ethical justification of debt as an investment underlies the rhetoric of finance and financialization. Close examination of the realities of contemporary financialized debt, however, reveal that much of this rhetoric is misleading and false. While the rhetoric of finance is unrelentingly oriented toward the future, the lived reality of debt is one of being constrained and haunted by the past. Relatedly, this rhetoric exhorts borrowing for investment, while finance has actually had the opposite effect of making consumer debt a necessity for the majority of Americans. Taken together, these realities of debt today contradict the rhetoric of finance as investment and undermine the ethical framework on which it depends.
In the future, toward death: Finance capitalism and security in Don DeLillo's ‘Cosmopolis’
Authors: Voelz Johannes 
Published: June 2018

AbstractThis article develops a reading of Don DeLillo's novel Cosmopolis that differentiates between two thematic and poetological axes running through the text. On the one hand, Cosmopolis explores the future-fixation of the risk regime of finance capitalism; on the other, it stages scenes of insecurity that physically threaten the protagonist and his world. Insecurity, the article argues, is a condition that throughout the text increasingly gains in appeal because it promises to offer an alternative to a world of managed risk. The concern with security emphasizes finitude and mortality, thus enabling a turn to existential matters that the virtual abstractions of finance have seemingly made inaccessible. While proposing an opposition between a logic of risk based on virtuality and a logic of (in)security based on authenticity, DeLillo's novel also suggests that it is impossible to break out of the logic of risk management pervading late modernity. The appeal of (in)security articulated in Cosmopolis rather lies in the promise to existentially revitalize life within the confines of financialized capitalism.
‘It's not cricket’: Financial time and postcolonial temporalities in Joseph O'Neill's ‘Netherland’
Authors: Mischke Dennis 
Published: June 2018

AbstractBased on a reading of Joseph O'Neill's 2008 novel Netherland, this article discusses the relationship between cricket and finance capitalism from the perspective of time and temporality. Despite its function as a global commodity, cricket inserts a flow of postcolonial time into the temporal streams of transnational market culture, neoliberalism, and the increasing financialization of the world. Set in the aftermath of 9/11 and before the financial crisis of 2008, Netherland juxtaposes the deviant temporal power of cricket with the time structures of finance capitalism to illustrate how the conduct of Wall Street before the crisis can be understood as a colonial appropriation. In O'Neill's novel, this conflict is embodied in the precarious friendship of a cosmopolitan Dutch financial analyst and a Trinidadian version of Jay Gatsby.
