Depositional facies of gas shale and its impact on shale reservoir of the Permian Shanxi Formation, Northern Ordos Basin
Authors: Guo Wei , Liu Honglin , Lan Chaoli 
Published: January 2017

Purpose
Based on core description, gas logging and laboratory analysis, this paper aims to study the controlling effect of the types of shale sedimentary microfacies in coal formations over shale reservoirs using the example of Shanxi formation in Northern Ordos Basin.

Design/methodology/approach
According to core observation, the authors selected typical samples of rock types for thin section analysis to determine the micro features and compositions of rocks.

Findings
By using core observation, we found that fine lithology in Shanxi formation included major shale, carbonaceous shale, partially carbonaceous shale, partially silty shale and silty shale with colors of gray, dark gray, black and/or gray. Shanxi Formation shale are deposited in plant-rich and plant-poor swamps, interdistributary depressions of delta plains, interfluvial depressions of meandering rivers as well as microfacies environment of natural levees and the distal crevasse splay.

Originality/value
Currently, the research on the shale gas in Shanxi Formation in the Ordos Basin is still in its infancy. There is yet no research on the fine-grained partition of the sedimentary facies in coal accumulation environment of Shanxi formation and the controlling effect of sedimentary microfacies over shale reservoirs.
Numerical simulation of combustor temperature performance of a high-temperature high-speed heat-airflow simulation system
Authors: Cai Chaozhi , Fan Leyao , Wu Bingsheng 
Published: January 2017

Purpose
This paper aims to understand the outlet temperature distribution of the combustor of a high-temperature, high-speed heat-airflow simulation system.

Design/methodology/approach
The paper uses numerical simulation to study the temperature distribution of the combustor of a high-temperature, high-speed heat-airflow simulation system. First, the geometrical model of the combustor and the combustion model of the fuel are established. Then, the combustion of fuel in the combustor is simulated by using FLUENT under various conditions. Finally, the results are obtained.

Findings
The paper found three conclusions: when the actual fuel–gas ratio is equal to the theoretical fuel–gas ratio, the temperature in the combustor of the high-temperature, high-speed heat-airflow simulation system (HTSAS) can reach its highest and the distribution is the most uniform. Although increases in the total temperature of the inlet air can increase the highest temperature in the combustor of the HTSAS, the average temperature of the combustor outlet will decrease. At the same time, it will lead to an uneven temperature distribution of the combustor outlet. When the spray angle of the kerosene droplet is at 30 degrees, the outlet temperature field of the combustor is more uniform.

Originality/value
The paper presents a method to analyze the combustion performance of fuel and the gas temperature distribution in the combustor. The results will lay the foundation for the gas temperature control of a combustor.

Authors: Pandey Anish , Parhi Dayal R. 
Published: January 2017

Purpose
This paper aims to design a Takagi–Sugeno fuzzy model with a simulated annealing hybrid algorithm (fuzzy-SAA) that was implemented for mobile robot navigation and obstacle avoidance in a cluttered environment.

Design/methodology/approach
The SAA is used to optimize the output parameters of the fuzzy controller. The ultrasonic range finder sensor and sharp infrared range sensor are used for calculating the different obstacle distances, such as front, right and left obstacle distance, for selecting the suitable steering angle control command in the environment.

Findings
The simulation and experimental results show the proposed method is feasible and valid for a wheeled mobile robot moving in a cluttered environment.

Originality/value
The developed fuzzy-SAA hybrid algorithm provides better results (in terms of navigation path length and time) as compared to previous works, which verifies the effectiveness and efficiency of the developed hybrid algorithm.
Experimental analysis of stresses in weld metal subjected to tensile load
Authors: S.S. Sampath , Rammohan Nethri , Shetty Reema , Shetty Sawan , M. Chithirai Pon Selvan 
Published: January 2017

Purpose
Stainless steel is one of the most important elements in structural design and application, and due to its excellent properties, it is widely used in industries for conventional structural engineering applications, such as thermal power plants, nuclear power plants, civil constructions, etc. (Mishra et al., 2014). A traditional tensile testing machine cannot determine the transversal stress–strain curves (Olden, 2002, 2013).

Design/methodology/approach
In the present study, identical mild steel specimen parts are welded at different intervals and then subjected to tensile loading. Welding is carried along the length of the specimen. Induced stresses are determined at the welded intervals and the stress–strain curve is obtained.

Findings
By considering the temperature of the weld at the interface, thermal stresses are determined. Brinell hardness number is determined at the interface and the base metal. Also, the change in the hardness at the heat-affected zone (HAZ) is found. Validation is carried out by comparing the results with the original stress–strain curve.

Originality/value
In the HAZ, there is a drop in the hardness number, which means that there is a change in the material property due to welding. The thermal stresses which develop at the interface can also play a very important role for property change. Results show that the stress developed due to the rise in temperature is lesser than that of normal stresses.

Quad-porosity shale systems – a review
Authors: Patwardhan Samarth D. , Famoori Fatemeh , Kumar Govindarajan Suresh 
Published: January 2017

PurposeThis paper aims to review the quad-porosity shale system from a production standpoint. Understanding the complex but coupled flow mechanisms in such reservoirs is essential to design appropriate completions and further, optimally produce them. Dual-porosity and dual permeability models are most commonly used to describe a typical shale gas reservoir.Design/methodology/approachCharacterization of such reservoirs with extremely low permeability does not aptly capture the physics and complexities of gas storage and flow through their existing nanopores. This paper reviews the methods and experimental studies used to describe the flow mechanisms of gas through such systems, and critically recommends the direction in which this work could be extended. A quad-porosity shale system is defined not just as porosity in the matrix and fracture, but as a combination of multiple porosity values.FindingsIt has been observed from studies conducted that shale gas production modeled with conventional simulator/model is seen to be much lower than actually observed in field data. This paper reviews the various flow mechanisms in shale nanopores by capturing the physics behind the actual process. The contribution of Knudson diffusion and gas slippage, gas desorption and gas diffusion from Kerogen to total production is studied in detail.Originality/valueThe results observed from experimental studies and simulation runs indicate that the above effects should be considered while modeling and making production forecast for such reservoirs.
Hazard identification and risk analysis for a reinforced concrete rolling mill
Authors: Hafida Kahoul , Rachid Chaib , Ahmed Bellaouar 
Published: January 2017

Purpose
Because of non-satisfactory results obtained at the iron rods steel mill, during the last period of work and to collect relevant data to facilitate rapid and efficient decision-making, the purpose of this study is to describe a global analysis method of risks encountered by companies resulting from their own effects or by their environment to integrate prevention as soon as the conception of work place. From this point of view, it seems that it is time for companies that did learn to master direct costs to learn how to control indirect costs, which means controlling the risks and learning to face them once they are detected.

Design/methodology/approach
The method of work used is hazard identification and risk assessment (HIRA), which is based on Kinney evaluation. The HIRA allowed the authors to collect and analyze different dangers and risks at work posts and consider different corrective measures to prevent damages. The HIRA techniques are based on identifying the different hazardous situations and the risk related to each working station; the risks are identified and are classified and mitigated accordingly. Using unique criteria, the objective of the risk assessment part is to assign to each risk a numerical value. The criteria used for classifying and ordering the risk importance depend greatly on the selected method.

Findings
Risks are identified, classified and mitigated accordingly using Kinney method criteria depending on three factors: frequency of exposure (NE), probability of occurrence (NP) and severity level (NG). The level of risk mitigation (NM) is obtained as the product of the three factors (NP, NG and NE). Using the Pareto plot (20-80 per cent), the authors highlighted the priorities to be taken in the order of importance of the most important causes to take targeted measures.

Originality/value
This work is an opportunity for the steel mill complex to start a global approach in prevention of risks and improve working conditions. This can be reached by taking into consideration the technical, organizational and human solutions; It would not be a better method to search for ways and means to reach better prevention of industrial and technological risks, but it will preserve health of workers and get to a global higher level of security. Also, the steel mill complex can be engaged in a continuous improvement process. Therefore, management of risks will be a relevant way to decrease undesirable effects due to the diverse activities of the company.
Spatial detection of outlier loci with Moran eigenvector maps
Authors: Wagner Helene H. , Chávez‐Pesqueira Mariana , Forester Brenna R. 
Published: January 2017

AbstractThe spatial signature of microevolutionary processes structuring genetic variation may play an important role in the detection of loci under selection. However, the spatial location of samples has not yet been used to quantify this. Here, we present a new two‐step method of spatial outlier detection at the individual and deme levels using the power spectrum of Moran eigenvector maps (MEM). The MEM power spectrum quantifies how the variation in a variable, such as the frequency of an allele at a SNP locus, is distributed across a range of spatial scales defined by MEM spatial eigenvectors. The first step (Moran spectral outlier detection: MSOD) uses genetic and spatial information to identify outlier loci by their unusual power spectrum. The second step uses Moran spectral randomization (MSR) to test the association between outlier loci and environmental predictors, accounting for spatial autocorrelation. Using simulated data from two published papers, we tested this two‐step method in different scenarios of landscape configuration, selection strength, dispersal capacity and sampling design. Under scenarios that included spatial structure, MSOD alone was sufficient to detect outlier loci at the individual and deme levels without the need for incorporating environmental predictors. Follow‐up with MSR generally reduced (already low) false‐positive rates, though in some cases led to a reduction in power. The results were surprisingly robust to differences in sample size and sampling design. Our method represents a new tool for detecting potential loci under selection with individual‐based and population‐based sampling by leveraging spatial information that has hitherto been neglected.
A prospective randomized controlled trial comparing early postoperative complications in patients undergoing loop colostomy with and without a stoma rod
Authors: Franklyn J. , Varghese G. , Mittal R. , Rebekah G. , Jesudason M. R. , Perakath B. 
Published: January 2017

AbstractAimA stoma rod or bridge has been traditionally placed under the bowel loop while constructing a loop colostomy. This is believed to prevent stomal retraction and provide better faecal diversion. However, the rod can cause complications such as mucosal congestion, oedema and necrosis. This single‐centre prospective randomized controlled trial compared outcomes after creation of loop colostomy with and without a supporting stoma rod. The primary outcome studied was stoma retraction rate; other stoma‐related complications were studied as secondary outcomes.MethodOne hundred and fifty‐one patients were randomly allotted to one of two arms, colostomy with or without a supporting rod. Postoperative complications such as retraction, mucocutaneous separation, congestion and re‐exploration for stoma‐related complications were recorded.ResultsThere was no difference in the stoma retraction rate between the two arms (8.1% in the rod arm and 6.6% in the no‐rod arm; P = 0.719). Stomal necrosis (10.7% vs 1.3%; P = 0.018), oedema (23% vs 3.9%; P = 0.001), congestion (20.3% vs 2.6%; P = 0.001) and re‐admission rates (8.5% vs 0%; P = 0.027) were significantly increased in the arm randomized to the rod.ConclusionThe stoma rod does not prevent stomal retraction. However, complication rates are significantly higher when a stoma rod is used. Routine use of a stoma rod for construction of loop colostomy can be avoided.
SUCCESSFUL IN THE LONG RUN: A META‐REGRESSION ANALYSIS OF PERSISTENT FIRM PROFITS
Authors: Hirsch Stefan 
Published: January 2017

AbstractWe study the profit persistence literature by applying meta‐regression analysis (MRA) to a set of 36 empirical papers, which analyze the persistence of abnormal firm profits over time. The analyzed literature provides evidence for a mediocre degree of persistence in abnormal profits. An initial analysis of the distribution of reported profit persistence estimates reveals some degree of excess variation. This points toward publication bias that favors significant results independent of their algebraic sign. The MRA, however, reveals that publication bias is particularly favoring results that indicate profit persistence and thus contradict the neoclassical model of perfect competition. Moreover, the MRA enables to control for heterogeneity driven by the study design. We find that the analyzed country (developing vs. developed), the applied econometric approach, as well as the analyzed period of time are significant drivers of heterogeneity in reported persistence estimates.

Authors: Aydemir Seda , Arukaslan Göze , Sarıdağ Serkan , Kaya‐Büyükbayram Işıl , Ylıdıran Yasemin 
Published: January 2017

AbstractPurposeTo compare two fiber post removal techniques in terms of fracture resistance and time required for post removal.Materials and MethodsPost space was prepared to a 9‐mm depth in each root canal. The roots were randomly divided into three groups of 15 specimens each. D.T. Light‐Posts were cemented in all groups. In group 1, fiber posts were removed using the D.T. Light‐Post‐removal kit; in group 2, Start‐X stainless‐steel ultrasonic tips were used. In group 3, fiber posts were left without removal (the control group). For all groups, fracture resistance (N) value was measured and recorded using a universal testing machine. Times required for fiber post removal were also recorded for the two study groups.ResultsThere was no significant difference between the control and removal kit groups for fracture resistance values (p = 0.233). The fracture resistance value of the ultrasonic group was found to be significantly lower than that of the control group (p = 0.001) as well as that of the removal kit group (p = 0.032). The fiber post removal time for the ultrasonic group was significantly longer than that for the removal kit group (p < 0.001).ConclusionCompared to the removal kit, removal of the fiber posts with an ultrasonic tip decreases the fracture resistance of the roots, although significantly more time is required.
Innovations in Treatment Delivery, Risk of Peritonitis, and Patient Retention on Peritoneal Dialysis
Authors: Piraino Beth 
Published: January 2017

AbstractEarly innovations in the delivery of peritoneal dialysis (PD) markedly improved its acceptability and lowered peritonitis rates. The standard osmotic agent was, and continues to be dextrose, an agent that is not ideal as it is readily absorbed. The development of icodextrin‐containing dialysis fluid has allowed a long dwell time to provide more effective ultrafiltration. The development of a smaller, more easily used automated cycler, led to an increase in the proportion of patients on the cycler as opposed to CAPD. Recently, new cyclers with better teaching tools and ease of use and communication with the training team have come on the market; data on outcomes using these cyclers are not yet available. Peritonitis continues to be a serious complication of PD although improvements in connectology and research on Staphylococcus aureus carriage have decreased peritonitis risk. Peritonitis rates continue to vary tremendously from one program to another, which may be in part due to failure to follow best demonstrated practices in training, care of the l catheter exit site, and prevention of peritonitis. Peritonitis rates should be expressed as episodes per year at risk and as organism‐specific rates to allow comparisons from one program to another, from one period to another and from a program to the published literature. The term technique failure is misused in PD. Patients leave PD for a host of reasons including transplantation. Transfer from PD to hemodialysis can be planned and have an excellent outcome or can be delayed or done emergently and have a less optimal outcome. The life plan of the patient with ESRD needs to be not only considered but also periodically revised as circumstances and patient wishes change.
Reuse and Biocompatibility of Hemodialysis Membranes: Clinically Relevant?
Authors: Upadhyay Ashish , Jaber Bertrand L. 
Published: January 2017

AbstractThe practice of reprocessing dialyzers for reuse, once predominant in the United States, has been steadily declining over the last 20 years. The professed roles of reuse in improving dialyzer membrane biocompatibility and lowering the risk of first‐use syndrome have lost relevance with the advent of biocompatible dialyzer membranes and favorable sterilization techniques. The potential for cost‐savings from reuse is also called into question by the easy availability of comparatively cheaper dialyzers and rising regulatory demands and operational cost of reprocessing systems. While the environmental concerns from additional dialyzer‐related solid waste from rising single‐use practice remains pertinent and requires development of safer dialyzer disposable system technologies, there is no meaningful medical rationale for the continued practice of dialyzer reuse in the twenty‐first century.
Tacrolimus interaction with nafcillin resulting in significant decreases in tacrolimus concentrations: A case report
Authors: Wungwattana Minkey , Savic Marizela 
Published: January 2017

AbstractTacrolimus (TAC) is subject to many drug interactions as a result of its metabolism primarily via CYP450 isoenzyme 3A4. Numerous case reports of TAC and CYP3A4 inducers and inhibitors have been described including antimicrobials, calcium channel antagonists, and antiepileptic drugs. We present the case of a 13‐year‐old patient with cystic fibrosis and a history of liver transplantation, where subtherapeutic TAC concentrations were suspected to be a result of concomitant TAC and nafcillin (NAF) therapy. The observed drug interaction occurred on two separate hospital admissions, during both of which the patient exhibited therapeutic TAC concentrations prior to exposure to NAF, a CYP3A4 inducer. Upon discontinuation of NAF, TAC concentrations recovered in both instances. This case represents a drug–drug interaction between TAC and NAF that has not previously been reported to our knowledge. Despite the lack of existing reports of interaction between these two agents, this case highlights the importance of therapeutic drug monitoring and assessing for any potential drug–drug or drug‐food interactions in patients receiving TAC therapy.
