Geocentralization and Thainess
Authors: Carter Jason Lee 
Published: October 2017

Purpose
Thailand desires to improve its economic competitiveness in the Southeast Asia-Pacific region and utilizes the World Economic Forum’s Global Competitiveness Report (GCR) on the 12 Pillars of Competitiveness to gauge this progress. The purpose of this paper is to study the outcomes for the fifth pillar on “Higher education and training” to identify the challenges to institutional management for the design and implementation of business administration programs.

Design/methodology/approach
The first hypothesis on causality and impact is a comparison of curricula design from published material between Thai and similar highly rated programs from the GCR using a statistical variance method. The second hypothesis is a proposed improvement model for implementation, geocentralization, analyzed using an inferential percentage differentiation.

Findings
The findings reveal a marked misalignment in relevant vs irrelevant curriculum design, with implementation performance results showing lower outcomes from traditional learning methods as compared to geocentralization.

Originality/value
Final remarks outline recommendations that Thai higher education administrators can utilize for improving curriculum design and implementation.
Rapid calculation method for estimating static and dynamic performances of closed hydrostatic guideways
Authors: Wang Zhiwei , Liu Yi , Wang Feng 
Published: October 2017

Purpose
The purpose of this paper is to establish a simplified model of the closed hydrostatic guideway for the rapid analysis of static and dynamic characteristics. Further, the influence of compressibility and dynamic frequency are taken into consideration in the new dynamic model.

Design/methodology/approach
The new model is based on the second kind of Lagrange equation. In this model, the closed hydrostatic guideway is supported by 12 pads, and each oil pad is equivalent to a nonlinear spring-damper system. The equivalent spring coefficient and damper coefficient of the oil pad are extracted by the three different equivalent methods. Finally, the validation experiments of step load response and dynamic stiffness are conducted on a hydrostatic guideway.

Findings
For solving the step response, the linear spring-damper model and the nonlinear spring-damper Model 1 are better than the nonlinear spring-damper Model 2. The accuracy of the three methods are very high for static stiffness calculation. For the calculation of dynamic stiffness, the nonlinear spring-damper Model 2 is better than the nonlinear spring-damper Model 1. The linear spring-damper model has low precision for dynamic stiffness calculation, especially at high frequency. The accuracy of the new model is validated by experiments.

Originality/value
The equivalent method of nonlinear spring-damper system has higher accuracy. Different equivalent methods should be adopted for different load types. The computational speeds of the new dynamic model with the three methods are much better than finite element method (about ten times).
Squeeze film performance of parallel annular plates by ferrofluid couple stress lubricant considering effects of rotational inertia
Authors: Dolatsara Nioosha Ghasemi , Daliri Maghsood , Shameli Moharram 
Published: October 2017

Purpose
The purpose of this paper is to investigate squeezing and rotating motions between two parallel annular discs lubricated by ferro-fluid couple stress lubricant in the presence of a uniform magnetic field.

Design/methodology/approach
Based upon the Stokes couple stress theory and ferro-hydrodynamic model of Shliomis, squeeze film characteristics between two parallel annular discs are obtained.

Findings
According to the results, it is found that the combined effects of couple stress and ferro-fluid lubricant increase squeeze film performance with respect to the classical Newtonian lubricant. However, an increase in the rotational inertia parameter reduces squeeze film characteristics.

Originality/value
This paper is relatively original and describes the squeeze film characteristics between two parallel annular discs with rotational inertia, couple stress and ferro-fluid lubricant effects.

Published: October 2017

Purpose
The purpose of this paper is to investigate the mechanisms of frictional wear stability of an activated carbon composite derived from palm kernel using phase transformation study.

Design/methodology/approach
The unlubricated sliding test was executed using a ball-on-disc tribometer at different loads with a constant speed, sliding distance and temperature.

Findings
Results of this paper suggest that stability of friction and wear of the test materials are primarily due to the phase transformation of the composite surface layer.

Research limitations/implications
However, the effectiveness of the transfer layer as a medium for low friction and wear is only limited at certain applied loads.

Originality/value
This is the first study, to the authors’ knowledge, to find out the mechanisms of low frictional wear properties of an activated carbon composite derived from palm kernel using phase transformation study.
Experimental study of starvation in grease-lubricated finite line contacts
Authors: Wang Zhijian , Shen Xuejin , Chen Xiaoyang , Han Qiang , Shi Lei 
Published: October 2017

Purpose
The purpose of this paper is to study starvation in grease-lubricated finite line contacts and to understand film-forming mechanisms of grease-lubricated finite line contacts.

Design/methodology/approach
A multiple-contact optical elastohydrodynamic (EHL) test rig is constructed to investigate the influences of lubricant properties on film thickness and lubrication conditions at different working conditions. The film thickness is calculated according to the relative light intensity principle. The degree of starvation is evaluated by the air–oil meniscus distance and the corresponding film thickness.

Findings
The experimental results show that for greases with high-viscosity base oil, the high-frequency fluctuation of film thickness is observed in low-speed operating conditions. Reducing the viscosity of the base oil and improving running speed can weaken the fluctuation of film thickness. The degree of starvation increases with increasing base oil viscosity, rolling speed and the crown drop. In addition, reducing the replenishment time by reducing the gap between the rollers also can increase the degree of starvation.

Originality/value
Starvation is often to occur in finite line contacts, such as roller bearings and gears; there are still limited finite line contact EHL test rigs, much less multiple-contact optical test rigs. Therefore, the present work is undertaken to construct the multiple-contact test rig and to evaluate the mechanism of starvation in finite line contacts.
The effect of the arc on annular-thrust aerostatic porous bearings
Authors: Khan Polina V. , Segu Dawit Zenebe , Hwang Pyung 
Published: October 2017

Purpose
Aerostatic porous bearings are important for guide rails and spindles. It is well-known that flow restrictors made of porous materials offer major advantages over conventional restrictors in such bearings, including design and manufacturing, load-carrying capacity, stiffness, damping and dynamic stability. Thus, this work numerically investigates the effect of the arc on a new combined annular-thrust aerostatic porous bearing.

Design/methodology/approach
The static characteristics of an annular-thrust aerostatic porous bearing were studied using a fast finite element scheme. The pressure distribution, radial load and thrust load were analyzed as functions of the arc, permeability and eccentricity.

Findings
The results reveal that the radial load achieves maximal values at an optimal arc value between 200 and 300, and the thrust load increases monotonically with increasing arc.

Originality/value
This work developed a new combined annular-thrust aerostatic porous bearing to investigate the effect of arc on the annular-thrust aerostatic porous bearings to increase the load-carrying capacity.

A high-dimensional classification approach based on class-dependent feature subspace
Authors: Chen Fuzan , Wu Harris , Dou Runliang , Li Minqiang 
Published: October 2017

Purpose
The purpose of this paper is to build a compact and accurate classifier for high-dimensional classification.

Design/methodology/approach
A classification approach based on class-dependent feature subspace (CFS) is proposed. CFS is a class-dependent integration of a support vector machine (SVM) classifier and associated discriminative features. For each class, our genetic algorithm (GA)-based approach evolves the best subset of discriminative features and SVM classifier simultaneously. To guarantee convergence and efficiency, the authors customize the GA in terms of encoding strategy, fitness evaluation, and genetic operators.

Findings
Experimental studies demonstrated that the proposed CFS-based approach is superior to other state-of-the-art classification algorithms on UCI data sets in terms of both concise interpretation and predictive power for high-dimensional data.

Research limitations/implications
UCI data sets rather than real industrial data are used to evaluate the proposed approach. In addition, only single-label classification is addressed in the study.

Practical implications
The proposed method not only constructs an accurate classification model but also obtains a compact combination of discriminative features. It is helpful for business makers to get a concise understanding of the high-dimensional data.

Originality/value
The authors propose a compact and effective classification approach for high-dimensional data. Instead of the same feature subset for all the classes, the proposed CFS-based approach obtains the optimal subset of discriminative feature and SVM classifier for each class. The proposed approach enhances both interpretability and predictive power for high-dimensional data.

Early urinary biomarkers of renal tubular damage by a high‐salt intake independent of blood pressure in normotensive rats
Authors: Washino Satoshi , Hosohata Keiko , Jin Denan , Takai Shinji , Miyagawa Tomoaki 
Published: October 2017

SummaryDietary sodium intake has been associated with progression to chronic kidney disease (CKD) as well as hypertension. A high‐salt intake causes renal damage independent of hypertension. Because traditional renal biomarkers are insensitive, it is difficult to detect renal injury induced by a high‐salt intake, especially in normotensive patients. Here, we investigated whether newly developed renal biomarkers could be detected earlier than traditional biomarkers under a high‐salt intake, in normotensive rats. Male Wistar Kyoto rats (WKY) received a regular (0.8% NaCl) or salt‐loaded (2, 4, and 8% NaCl) diet from 9 to 17 weeks of age. A urine sample was obtained once a week and urinary vanin‐1, neutrophil gelatinase‐associated lipocalin (NGAL), and kidney injury molecule‐1 (Kim‐1) were measured. At 17 weeks of age, 8% salt‐loaded WKY showed histopathological renal tubular damage and elevated Rac1 activity in renal tissues. Although there was no significant increase in serum creatinine, urinary albumin, N‐acetyl‐β‐D‐glucosaminidase (NAG), or Kim‐1 during the study period among the groups, urinary vanin‐1 and NGAL significantly increased in 8% salt‐loaded WKY from 10 to 17 weeks of age. These results suggest that urinary vanin‐1 and NGAL, which might be induced by salt per se, are potentially earlier biomarkers for renal tubular damage in normotensive rats under a high‐salt intake.
Type VI secretion systems in plant‐associated bacteria
Authors: Bernal Patricia , Llamas María A. , Filloux Alain 
Published: October 2017

SummaryThe type VI secretion system (T6SS) is a bacterial nanomachine used to inject effectors into prokaryotic or eukaryotic cells and is thus involved in both host manipulation and interbacterial competition. The T6SS is widespread among Gram‐negative bacteria, mostly within the Proteobacterium Phylum. This secretion system is commonly found in commensal and pathogenic plant‐associated bacteria. Phylogenetic analysis of phytobacterial T6SS clusters shows that they are distributed in the five main clades previously described (group 1–5). The even distribution of the system among commensal and pathogenic phytobacteria suggests that the T6SS provides fitness and colonization advantages in planta and that the role of the T6SS is not restricted to virulence. This manuscript reviews the phylogeny and biological roles of the T6SS in plant‐associated bacteria, highlighting a remarkable diversity both in terms of mechanism and function.
Laparoscopic ventral hernia repair using only 5‐mm ports
Authors: Bell‐Allen Nicholas , O'Rourke Harriet , Hong Lisa , O'Rourke Nicholas 
Published: October 2017

BackgroundThe technique of laparoscopic ventral hernia repair has been evolving since it was first described over 20 years ago. We report a new technique where polyester mesh was back loaded through a 5‐mm port site, coming into contact with the skin. This avoids the need for any 10–12‐mm ports.MethodsA prospective database of laparoscopic ventral hernia repairs was examined. A single surgeon performed 344 laparoscopic ventral hernia repairs using this technique over 60 months. Follow‐up was conducted by both clinical and independent phone review. Surgical technique: Laparoscopic access was achieved via a 5‐mm optical port, adding two, or occasionally three, 5‐mm extra ports. Hernia contents were reduced and the extra‐peritoneal fat excised; 5‐mm tooth graspers were placed through the lateral port and then in a retrograde fashion through the uppermost port. The port was removed, and the mesh pulled back into the abdominal cavity and positioned with a minimum of 3‐cm overlap. The mesh was fixed using absorbable tacks and sutures.ResultsMost patients had primary umbilical hernias. There was one case of mesh infection due to enteric organisms. This occurred in a patient undergoing repair of a stoma site hernia, resulting from a Hartmann's procedure for perforated diverticulitis. There was no other evidence of acute or chronic mesh infection despite cutaneous contact with the mesh. In this series, there was an overall hernia recurrence rate of 2.4%.ConclusionLaparoscopic ventral hernia repair using only 5‐mm ports is a safe, effective technique with no extra risk of infection.
Filter Adsorption of Anidulafungin to a Polysulfone‐Based Hemofilter During CVVHD In Vitro
Authors: Kolbinger Peter , Gruber Michael , Roth Gabriel , Graf Bernhard M. , Ittner Karl‐Peter 
Published: October 2017

AbstractCandidemia is frequent in critically ill patients, especially in combination with an acute kidney injury (AKI). Echinocandins generally are recommended for therapy of such infections. Recent studies found no need for dosage adjustment in patients with end‐stage renal disease receiving hemodialysis, or patients with AKI receiving continuous venovenous hemofiltration. The aim of this in vitro study was to examine the adsorption of anidulafungin to the surface of the hemofilter during continuous venovenous hemodialysis (CVVHD) and its effect on anidulafungin concentrations. The concentration of anidulafungin in the dialyzed fluid, and the dialysate during CVVHD in vitro was examined using three different dialyzed fluids (saline; saline with 40 g/L human albumin; and a mixture of human erythrocytes and fresh frozen plasma). After the end of dialysis, the hemofilter was opened and portions of the filter capillaries were also analyzed to determine the amount of anidulafungin adsorbed. When dialyzing saline, about 99% of the anidulafungin used adsorbed to the hemofilter capillaries; in the experiments with saline with 40 g/L albumin, about 60% adsorbed to the hemofilter's surface, and when blood was dialyzed, 35% was found adsorbed after analyzing the filter capillaries. Anidulafungin was not detectable in the dialysate of any of the experiments, consequently the dialysis clearance was 0 mL/min. In conclusion, during CVVHD in vitro we found remarkable adsorption of anidulafungin to the hemofilter's surface, yet the effect on the tissue concentration needs further examination.

Published: October 2017

SummaryBackgroundTherapeutic drug monitoring (TDM) in inflammatory bowel disease (IBD) patients receiving anti‐tumour necrosis factor (TNF) agents can help optimise outcomes. Consensus statements based on current evidence will help the development of treatment guidelines.AimTo develop evidence‐based consensus statements for TDM‐guided anti‐TNF therapy in IBD.MethodsA committee of 25 Australian and international experts was assembled. The initial draft statements were produced following a systematic literature search. A modified Delphi technique was used with 3 iterations. Statements were modified according to anonymous voting and feedback at each iteration. Statements with 80% agreement without or with minor reservation were accepted.Results22/24 statements met criteria for consensus. For anti‐TNF agents, TDM should be performed upon treatment failure, following successful induction, when contemplating a drug holiday and periodically in clinical remission only when results would change management. To achieve clinical remission in luminal IBD, infliximab and adalimumab trough concentrations in the range of 3‐8 and 5‐12 μg/mL, respectively, were deemed appropriate. The range may differ for different disease phenotypes or treatment endpoints—such as fistulising disease or to achieve mucosal healing. In treatment failure, TDM may identify mechanisms to guide subsequent decision‐making. In stable clinical response, TDM‐guided dosing may avoid future relapse. Data indicate drug‐tolerant anti‐drug antibody assays do not offer an advantage over drug‐sensitive assays. Further data are required prior to recommending TDM for non‐anti‐TNF biological agents.ConclusionConsensus statements support the role of TDM in optimising anti‐TNF agents to treat IBD, especially in situations of treatment failure.
