Optimizing the Application of Underbalanced Drilling Through the Use of Air and Foam Systems in Low-Pressure Gas Reservoirs
Authors: Porter Mika , Hill Adam , Vieira Paco , Wuest Chad , Gregorio Adrian Paul , Sardo Antonio , Orta Cesar 
Published: January 2018

Abstract
In global underbalanced drilling (UBD) applications, the main contributing factor for downhole fires is often attributed to the use of air as the primary gaseous phase in the reservoir interval. The industry has adopted a general practice to avoid using air in UBD operations in the presence of hydrocarbons. This paper challenges this paradigm by discussing the planning and application of a successful air-foam UBD application in Australia to drill a low-pressure, highly depleted, gas-bearing reservoir. By using air as the primary fluid medium and eliminating the need for membrane-produced nitrogen, the UBD cost was reduced by 25% and reservoir deliverability exceeded the production expectations. This paper discusses the risk mitigations, modeling, and technical justification applied to the challenging project to demonstrate that even when inert gases may be the recommended choice, air can be used safely in some cases to optimize operational efficiency and cost.

Authors: Yousefsani Bahareh Sadat , Mohajeri Seyed Ahmad , Moshiri Mohammad , Hosseinzadeh Hossein 
Published: January 2018

Background:Molecularly imprinted polymers (MIPs) are synthetic polymers that have a selective site for a given analyte, or a group of structurally related compounds, that make them ideal polymers to be used in separation processes.Objective:An optimized molecularly imprinted polymer was selected and applied for selective extraction and analysis of clozapine in rat brain tissue.Methods:A molecularly imprinted solid-phase extraction (MISPE) method was developed for preconcentration and cleanup of clozapine in rat brain samples before HPLC-UV analysis. The extraction and analytical process was calibrated in the range of 0.025-100 ppm. Clozapine recovery in this MISPE process was calculated between 99.40 and 102.96%. The limit of detection (LOD) and the limit of quantification (LOQ) of the assay were 0.003 and 0.025 ppm, respectively. Intra-day precision values for clozapine concentrations of 0.125 and 0.025 ppm were 5.30 and 3.55%, whereas inter-day precision values of these concentrations were 9.23 and 6.15%, respectively. In this study, the effect of lipid emulsion infusion in reducing the brain concentration of drug was also evaluated.Results:The data indicated that calibrated method was successfully applied for the analysis of clozapine in the real rat brain samples after administration of a toxic dose to animal. Finally, the efficacy of lipid emulsion therapy in reducing the brain tissue concentration of clozapine after toxic administration of drug was determined.Conclusion:The proposed MISPE method could be applied in the extraction and preconcentration before HPLC-UV analysis of clozapine in rat brain tissue.
Antifogging and Antireflective Coatings by Spin-LbL Assembly of SiO2 and ZrO2 Nanoparticles
Authors: Yang Fusheng , Wang Peng , Yang Xiaoli , Cai Zaisheng 
Published: January 2018

Background:
Fogging is a common phenomenon and often causes trouble to people in
daily life. Antifogging (AF) and Antireflective (AR) coatings can be effectively used to provide resistance
to fogging and maintain the optical clarity in day-to-day life. For this reason, they are useful
for maintaining optical clarity in optical instrument and display devices.

Methods:
Antifogging and antireflective coatings were fabricated using a Spin-LbL assembly process,
and this process is driven by electrostatic interactions between the positively charged ZrO2 NPs
and negatively charged SiO2 NPs.

Results:
The textured surfaces and void fraction can signicantly enhance the wettability of surfaces
with water. And this may result in enhanced AF properties. In the Water contact angles (WCA) test, the
ZrO2/SiO2 and SiO2/ZrO2 coatings were all superhydrophilic (almost 0°, less than 0.04 s). In the boiling test
and low temperature AF test, the ZrO2/SiO2 and SiO2/ZrO2 samples showed excellent AF properties.

Conclusion:
Antifogging and antireflective coatings were fabricated via Spin-LbL assembly of the
positively charged ZrO2 NPs and negatively charged SiO2 NPs followed by calcination. The resultant
coatings showed excellent AF properties due to the superhydrophilicity of the coating, exhibited excellent
AR properties due to the low refractive index coating and an appropriate coating thickness,
and showed excellent superhydrophilic properties due to a nano-roughness structure.

The Justiciability of Administrative Decisions: A Redundant Concept?
Authors: Finn Chris 
Published: January 2018

The non-justiciability of certain executive decisions is based upon a number of notions including that of ‘polycentricity’, the unsuitability of certain types of power for review, deference to executive judgment, and the question of the judicially enforceable limits to power. In this article, it is argued that the concept is redundant. It is sufficient to consider whether a ground of review, invoked with an appropriate regard for the legalities merits distinction, is available. There is no further question of ‘justiciability’.It is questionable whether it has ever really made sense to talk of ‘justiciability’ as a discrete notion, rather than justiciability upon this or that ground. Historically, it is trite to observe that questions of the existence and limits of the prerogative powers have been justiciable since at least the upheavals of the 17th century, even while courts would steadfastly refuse to examine the manner in which those powers were exercised. Thus, even prior to the decision in Council of Civil Service Unions v Minister for the Civil Service (‘CCSU’), non-justiciability in relation to prerogative powers meant simply the non availability of grounds of review other than the simplest form of ultra vires. CCSU itself established the potential availability of review of such powers for denial of procedural fairness, leaving open the question of whether the various abuse of power grounds might also be available. In short, the issue appears to be whether a decision is justiciable upon this or that ground of review, rather than the blanket availability or non availability of review. Once this point is grasped the inchoate concept of ‘justiciability’ becomes problematic at best. One need simply ask whether one or more grounds of review can be made out.
Class Actions against Multiple Respondents
Authors: Morabito Vince 
Published: January 2018

On one reading of the approach by some Judges of the Federal Court to complex cases involving more than one respondent, particularly where the conduct in question involves a complicated or lengthy series of transactions, those cases should simply not be brought as class actions. If that reading is correct, then to put it bluntly, defendants are more likely to escape liability if by their conduct they cause harm or loss to more people over a greater period of time, and if they do so in concert with others.Class actions are unlikely to flourish in Australia without a change in attitudes, both in the profession and the judiciary … Many Australian judges may still view class actions as predatory litigation instituted for the advantage of entrepreneurial lawyers.In March 2002 the class action regime introduced by the Commonwealth Parliament, through the addition of a new Part IVA to the Federal Court of Australia Act 1976 (Cth), celebrated its tenth ‘birthday'. During this time, a number of important issues, concerning the interpretation and application of Part IVA, have emerged.
Mix Design of Self Compacting Concrete Based on Ultra High Compressive Strength Flow Mortar Mix
Authors: Wulan Soca Anggoro , Satyarno Iman , Saputra Ashar 
Published: January 2018

Mix design of Self Compacting Concrete or SCC is not straight forward because many parameters control its rheological properties. The case becomes more complicated if high compressive strength is also to be achieved. Therefore simpler approach is used, that is by firstly determining the flow mortar mix which is easier to be designed even with the requirement of ultra-high compressive strength. The mix design of SCC is then determined by simply adding the coarse aggregate with a certain amount of that mortar mix. In this research the ultra-high compressive strength flow mortar was made of Type I cement, 15% of cement weight silica fume, weight ratio of cement and curve No IV sand was 1: 0.35. The water-cementious ratio was 0.22 and the amount of plasticizer was 1.3%, 1.4%, 1.5% and 1.6% of the cement weight. For the SCC, the used coefficient was taken to be 1.4, 1.6, and 1.8 of the volume of that aggregate void for mortars, the aggregate value was at the volume of the remaining count of mortar and its size was 4.8 mm - 9.6 mm. Test results show that the mortar flow ability was 170 mm, 180 mm, 220 mm and 250 mm, where the achieved compressive strength was 83.1 MPa, 96.8 MPa, 111.4 MPa, and 135.5 MPa respectively. Mortar mix with 1.6% super plasticizer was then used for making the SCC and the results show that the concrete flow were 460 mm, 580 mm and 660 mm and the compressive strength were 88.2 MPa, 100.0 MPa, and 97.9 MPa. It can be concluded that using this simpler approach the SCC can have 580 mm flow and 100 MPa compressive strength
Contribution of Tea Root Reinforcement to Soil Shear Strength on Slope Stability
Authors: Abubakar Mukhsin 
Published: January 2018

Roots played important role in the process of stabilizing the soil mass. The geo-mechanical and soil-hydrological aspects on the slope are determined by, one of it, the root reinforcement. The role of root branching series with diameter differentiation is greatly determining its tensile stress. The tensile stress from the interaction between the root and the soil, could it contribute to increasing the shear strength of the slope stability. The purpose of this research was to identify the tensile stress on root branching series that interacted with the soil and created additional cohesion as a shear strength contribution to the slope stability. Testing on the root pulling force was conducted on slope prototype with angle 30o to 40o and has been planted with tea vegetation. A tripod that was completed with strain gauge as the recording instrument was used. Testing was conducted on two and three root branching, also on each unit by observing the diameter. This testing method was done in saturated soil condition. The tensile stress result showed that increasing diameter of the tea root, an increase was noticed, and also result in the equation of TFr = 0.089e0.516d. Root diameter increase on two and three root branching to one unit of tea vegetation showed that the stress increase was significant. When observed, in the root diameter differentiation of 4 mm to 6 mm, the stress on two and three root branching and one unit of tea vegetation were respectively 5.94%, 12.30%, and 35.42%. The contribution of additional cohesion caused by root-soil interaction to soil shear strength apparently could increase slope stability.
The 16th Party Congress in China: A Note on Personnel Changes
Authors: Brødsgaard Kjeld Erik 
Published: January 2018

At the recent 16th Party Congress a comprehensive change of the Chinese
leadership was carried through. Even though there was much
speculation as to whether Jiang Zemin and his generation would retire
as scheduled, the change of the old guard took place without much
drama when the congress finally convened in Beijing.
How do we evaluate this development? Does it mean that Chinese
politics have matured in the sense that major decisions now conform to
fixed rules and regulations rather than factional politics? Has the Chinese
political process become more transparent? Have consensual decision-
making processeses finally taken over, relegating patrimonial
policies to a phenomenon of the past? Since the mid-1990s, clear and
detailed regulations for the selection and appointment of leading cadres
have been promulgated. Is the 16th Party Congress the final step in
this process of procedural normativization? Before attempting to answer
these questions, this paper will first deal with the personnel
changes that took place at the 16th Party Congress and the Central Committee
(CC) meeting shortly after the conclusion of the conference.
Socialpolitik eller social struktur? Inkomsttransfereringar, socio-demografiska faktorer och fattigdom i Frankrike och de nordiska länderna

Social Policy or Social Structure?
Income Transfers, Socio demographic Factors and Poverty in the Nordic Countries and in France

The paper compares poverty in Denmark, Finland, Norway, Sweden and France. We have (1) descriptive/analytical and (2) methodological goals.
(1) We pool the four Nordic countries into a single data set and compare France with this “Scandinavia”. The results give strong evidence to the existence of the homogenous Scandinavian model in terms of incidence of poverty, poverty profiles, and the effectiveness of social policy.
(2) The methodological objective is to “change the world” and simulate what would happen if France had the Scandinavian social structure – but its own social policy – and vice versa. Our re-weighting simulations show that the results of the “Scandinavization” of France depend on the method of simulation.
First, a static simulation, changing the socio-economic structure, but preserving the present median incomes and poverty lines as they are, would almost eradicate poverty in France. The „Francofication“ of Scandinavia would lead to dramatic results in Scandinavia: the number of persons totally dependent on social transfers would increase, the effectiveness of transfer systems would decrease, and the poverty rate would rise near to the actual French figures.
Second, in dynamic simulation we also change poverty lines to correspond actual median income (in “Scandi-France” the median income would rise – because of increased female labor force participation – and in “Franco-Scandinavia” decrease – because of lower female employ-ment). In “Scandi-France” the poverty rate would decrease close to the present Scandinavian figures, but the poor would be richer that the poor actually are in France. In “Franco-Scandinavia” the extension of poverty would be about the same as nowadays but the poor would be worse-off than they now are.
In sum, differences in the French and Scandinavian poverty rates are explained by the dynamic interplay between social security and structural variables. However, differences in the family structure and in labor market behavior seem to be more important explanatory factors: about 2/3 of differences between countries are explained by these structural factors, while 1/3 is explained by income transfer systems. However, it is important to remember that these background factors are greatly affected by the institutional set-ups of the welfare states.
Komparation i kritisk realistisk perspektiv
Authors: Wad Peter

Comparison in a critical realist perspective

With the rise of critical realist social science, time has come to ask whether this approach can enhance comparative methodology in sociology.
This article contends that although critical realist sociologists argue in favour of comparative studies, they are yet to formulate a genuine comparative methodology (paradox 1). They refer to the comparative tradition without scrutinizing it from a critical realist perspective. When such an assessment is made of core comparative methodologies, the conclusion is that postwar comparative sociology has serious methodological flaws which are rooted in Mill’s inductive logic from 1843 and modern empirical-analytical science philosophy (paradox 2). However, a closer examination of Charles Ragin’s quali-tative comparative analysis and Thomas Janoski & Alexander M. Hicks’ new comparative political economy indicates that it is possible to develop a substantial and complex comparative methodology from these contri-butions and even to address the enhanced ’Dalton Problem’ of our time: globalisation. The conclusion is that a pertinent and critical realist comparative methodology can emerge from the contemporary
stream of comparative sociology.
Moraliseringen af seeren

Lilie Chouliaraki: The Moralisation of the Spectator. On the September 11th live footage

In this paper, I discuss extracts of the September 11th live footage on television from the vantage point of discourse, that is of how the reported event “comes to mean“, how it becomes intelligible through television’s meaning-making operations. Specifically, I study the mediation of the September 11th as a mediation of “distant suffering“, drawing upon the work of Luc Boltanski (1999) on “morality, media and politics“. My aim is to identify the ways in which the September 11th television spectacle engages the affective potential of the spectator and evokes a specific disposition to act upon the suffering – that is, to act politically. My perspective on the September 11th thus concerns the televisual mediation of distant suffering and its moralising effects on the spectator. First, I introduce the problematic of representing distant suffering in terms of, what Boltanski calls, a “politics of pity“ – a politics that aims to resolve the Spacetime dimensions of mediation in order to establish a sense of “proximity“ to the events and, so, engage the spectator emotionally and ethically. Second, I contrast three different modes (or “topics“) of representing suffering, by reference to three live footage extracts from the Danish national television channel (DR): street shots of Manhattan, just after the Twin Towers’ collapse; the summary of the day events, with shots from the second plane collision and President Bush’s first public statement; a long shot of the Manhattan skyline burning.
I describe each “topic“ in terms of its Spacetime dimensions, its distinctive semiotic elements, and the affective mode and moral horizon it opens up for the spectator. In concluding, I briefly touch upon implications for the “moralisation“ of the spectator, involved in the September 11th “topics“ of suffering.
