Published: January 2017

AbstractThe purpose of this study was to compare muscle recovery in the lower extremities following the newly developed bi-cruciate substituting (BCS) to posterior stabilized (PS) total knee arthroplasty (TKA) in the Asian population. Forty-one knees in 41 patients undergoing BCS-TKA (41 female, average age: 71 ± 8.8) and 34 knees in 34 patients undergoing PS-TKA (33 female, average age: 73 ± 7.2) were included in this study. The maximum isometric power of the quadriceps and hamstring muscles was measured preoperatively, and at 1, 3, 6, and 12 months after surgery using a handheld dynamometer. Postoperative muscle recovery was calculated regarding preoperative muscle power as 100%. Pre- and postoperative range of knee motion, femorotibial angle, and clinical scores (Knee Society score and function score) were also compared. No significant difference in sex, age, preoperative quadriceps, or preoperative hamstring power was observed between the BCS and PS-TKA groups. When regarding the preoperative muscle power as 100%, quadriceps power at 1, 3, 6, and 12 months following BCS-TKA was 61.2 ± 22%, 86.3 ± 28.3%, 97 ± 27.4%, and 112.4 ± 30.8%, respectively. Quadriceps power at 1, 3, 6, and 12 months following PS-TKA was 72.4 ± 20.8%, 84 ± 16.9%, 95 ± 20.7%, and 110.8 ± 27%, respectively. Hamstring power at 1, 3, 6, and 12 months following BCS-TKA was 96.3 ± 30%, 111.4 ± 35%, 120 ± 37%, and 125 ± 31%, respectively. Hamstring power at 1, 3, 6, and 12 months following PS-TKA was 95 ± 25%, 112.4 ± 27%, 117 ± 38.5%, and 120.4 ± 18.5%, respectively. No significant difference in muscle power recovery was observed at 3 (p = 0.995), 6 (p = 0.944), and 12 (p = 0.917) months after surgery between the two groups. No significant difference of the clinical score was observed between the groups (Knee Society score: p = 0.479, function score: p = 0.342). No significant difference in muscle recovery and clinical score were observed between the BCS and PS-TKA groups. Longer follow-up is needed for the evaluation of efficacy of BCS-TKA in the Asian populations.

Published: January 2017

AbstractThe optimized production of MBF-HG6, which is a novel salt-tolerant alkaliphilic bioflocculant produced by Oceanobacillus polygoni with its application in tannery wastewater treatment was investigated in this study. It was found the optimal carbon source, nitrogen source, cation, and initial pH of the medium for bioflocculant production were starch, urea, Fe2+, and pH 9.0, respectively. The best stability in the temperature range was from 0 to 80°C and the purified MBF-HG6 contained polysaccharides of 81.53% and proteins of 9.98%. The carboxyl, hydroxyl, and amino groups were determined in bioflocculants, while the optimized bioflocculating activity was observed as 90.25% for the dosages of 6.96mL MBF-HG6, 4.77mL CaCl2 (1%, m/v), and 19.24g/L NaCl using response surface methodology. In addition, SS and turbidity removal rates of the tannery wastewater (4g/L MBF-HG6) could, respectively, reach 46.49% and 91.08%, indicating that the great potential was emerged in enhancement of tannery wastewater treatment by MBF-HG6.
Improving the accuracy of likelihood-based inference in meta-analysis and meta-regression
Authors: Kosmidis I. , Guolo A. , Varin C. 
Published: January 2017

Summary
Random-effects models are frequently used to synthesize information from different studies in meta-analysis. While likelihood-based inference is attractive both in terms of limiting properties and of implementation, its application in random-effects meta-analysis may result in misleading conclusions, especially when the number of studies is small to moderate. The current paper shows how methodology that reduces the asymptotic bias of the maximum likelihood estimator of the variance component can also substantially improve inference about the mean effect size. The results are derived for the more general framework of random-effects meta-regression, which allows the mean effect size to vary with study-specific covariates.
Whole genome sequencing and assembly of aCaenorhabditis elegansgenome with complex genomic rearrangements using the MinION sequencing device
Authors: Tyson JR , O’Neil NJ , Jain M , Olsen HE , Hieter P , Snutch TP 
Published: January 2017

ABSTRACTAdvances in 3rdgeneration sequencing have opened new possibilities for ‘benchtop’ whole genome sequencing. The MinION is a portable device that uses nanopore technology and can sequence long DNA molecules. MinION long reads are well suited for sequencing andde novoassembly of complex genomes with large repetitive elements. Long reads also facilitate the identification of complex genomic rearrangements such as those observed in tumor genomes. To assess the feasibility of thede novoassembly of large complex genomes using both MinION and Illumina platforms, we sequenced the genome of aCaenorhabditis elegansstrain that contains a complex acetaldehyde-induced rearrangement and a biolistic bombardment-mediated insertion of a GFP containing plasmid. Using ∼5.8 gigabases of MinION sequence data, we were able to assemble aC. elegansgenome containing 145 contigs (N50 contig length = 1.22 Mb) that covered >99% of the 100,286,401 bp reference genome. In contrast, using ∼8.04 gigabases of Illumina sequence data, we were able to assemble aC. elegansgenome in 38,645 contigs (N50 contig length = ∼26 kb) containing 117 Mb. From the MinION genome assembly we identified the complex structures of both the acetaldehyde-induced mutation and the biolistic-mediated insertion. To date, this is the largest genome to be assembled exclusively from MinION data and is the first demonstration that the long reads of MinION sequencing can be used for whole genome assembly of large (100 Mb) genomes and the elucidation of complex genomic rearrangements.

Authors: Zhang Yingjun , Shao Yawei , Shi Qiumei , Wang Yanqiu , Meng Guozhe , Li Ping 
Published: January 2017

Purpose
The purpose of this paper was to research the influence of polyaniline/montmorillonite (PANI/OMMT) composite powder content on the corrosion protection of epoxy (EP) coating.

Design/methodology/approach
The polyaniline/montmorillonite/epoxy (PANI/OMMT/EP) coatings containing different contents of PANI/OMMT composite powder were prepared on steel. The corrosion protection performances of PANI/OMMT/EP coatings in 3.5 per cent NaCl solutions were investigated by electrochemical impedance spectroscopy. The barrier property of coatings was examined using water absorption analysis. The structure and crosslink density of coatings were examined using scanning electron microscopy and differential scanning calorimetry, respectively.

Findings
The PANI/OMMT composite powder could enhance the barrier properties of the EP coating and reduce the corrosion rate of the steel beneath the coating. The coating showed the best corrosion protection performance when 3 per cent PANI/OMMT powder was added to the coating.

Originality/value
The research clarified the influence of PANI/OMMT content on the corrosion protection of coating from two aspects: one is the barrier performance of the coating; the other is the corrosion inhibitors for metal substrate.
Effects of laser remelting on surface-interface morphologies, bonding modes and corrosion performances of arc-sprayed Al coating
Authors: Wenming Liu , Tianyuan Sheng , Dejun Kong 
Published: January 2017

Purpose
The purpose of this paper is to provide an experimental basis for studying the effects of laser remelting on the surface modification of arc-sprayed Al coating.

Design/methodology/approach
A layer of arc-sprayed Al coating on S355 steel was remelted with a CO2 laser, and the surface-interface morphologies, compositions of chemical elements and phases of Al coating were analyzed with scanning electron microscopy, energy disperse spectroscopy and X-ray diffraction, respectively. The effects of laser remelting on compositions of chemical elements and bonding performance of Al coatings were discussed.

Findings
The result shows that there are some pores existing on the Al coating surface after arc spraying, and the combination mode of coating interface is primarily composed of mechanical bonding. The pores on the Al coating reduce after laser remelting, which improves the compact performance, and the mechanical binding mode by arc spraying is changed into metallurgical bonding. The Fe and Al atoms at the coating interface are distributed with gradient, and the stratified enrichment is evident, which improves binding performance of the Al coating. The Al coating exhibits general corrosion before laser remelting and local corrosion after laser remelting, which improves the corrosion resistance of Al coating.

Originality/value
The arc-sprayed Al coating is remelted by CO2 laser, improving its microstructures and bonding mode with the substrate.
In pursuit of innovation value in building projects
Authors: Maghsoudi Soroush , Duffield Colin , Wilson David 
Published: January 2017

Purpose
Although the construction industry is known for its low level of innovation and slow pace of change, some of its characteristics not only make this sector unique but also provide some opportunities to innovate. Innovation evaluation has become one of the priorities for building practitioners. This study aims to develop a practical methodology to evaluate the outcomes of innovation in small building and construction projects.

Design/methodology/approach
The research used three real case projects and information along with what was found in the literature. A framework was developed based on an extensive literature review of innovation outcomes evaluation.

Findings
The outcomes of the building projects were categorized into six categories of economic, quality, social, environmental, satisfaction and soft and organizational impacts. It was found that the outcomes of innovative practices in construction projects could be evaluated if subjective assessment is tolerated. The findings of this research are limited to the domestic and medium-density building projects, thus the outcomes might be generalized with appropriate care. The proposed practical framework would assist practitioners in the field of building and construction to realize the impacts of innovation introduced in their projects. The project owners and developers could be the main users of this framework.

Originality/value
Previously developed models or frameworks have mainly remained at the abstract level that could be used as guidelines, but the proposed framework in this study is practical and applicable to real building projects.
Investor reaction to R&D investment
Authors: Li Xin , Wang Tienan 
Published: January 2017

Purpose
This paper aims to examine the impact of research and development (R&D) investment on firms’ stock price from the perspective of investors.

Design/methodology/approach
Building on signaling theory, the authors propose that R&D investment sends important signals to the investment community regarding future growth, which in turn impacts investor reaction to such investment.

Findings
Using a sample of listed pharmaceutical firms in China from 2007 to 2011, the authors find that R&D investment has a positive effect on firms’ stock price, indicating that investors have a positive reaction to R&D investment signals. Further, the authors find that the signaling role of new product announcements mediates this relationship between R&D investment and investor reaction.

Originality/value
The authors also find that the signaling role of development capacity (DC) has a moderating effect on the relationship between innovation activities (i.e. R&D investment and new product announcements) and investor reaction, such that DC strengthens the positive effect of R&D and new product announcements on investors.
Increasing innovation through engagement
Authors: Walton Abram L.J. , Glassman Brian , Sandall Darrel L. 
Published: January 2017

Purpose
This paper aims to investigate the phenomenology behind how an idea stock market created employee engagement of 80 per cent+ within the largest telecom company in Portugal. More importantly, this case study investigates the results created using this system, and whether the “investment/betting” process yielded successful and replicable results.

Design/methodology/approach
This critical review took the form of an exploratory-grounded theory study. Initial conversations led to creation of questionnaires regarding the internal workings of Sonaecom’s idea market, implementation methods, incentive structures, necessary cultural adjustments, system outcomes and topics related to idea screening, types of users, herd behavior, idea storage, diffusion, implementation and perceptions of the idea market and its success.

Findings
The idea market produced engagement outcomes nearly twice that of standard industry engagement methodologies and showed promise for increasing corporate innovation outcomes.

Research limitations/implications
This study was limited to a single idea market within one company. As such, the conclusions from the study are limited in their generalizability to other companies implementing idea markets.

Practical implications
Because the challenges faced by Sonaecom are the same challenges faced by any company implementing an idea market, the findings from the study have important practical implications for any organization implementing an idea market.

Social implications
There are behavioral, psychological and leadership implications for organizations implementing an idea market.

Originality/value
Based on a thorough literature review, no other study has been made of Sonaecom’s Idea Market system, nor has a study of this depth and breadth been completed with any idea market system. The findings of the study have broad implications for any organization seeking to implement an idea management system.
Determinants of bank profitability in Tunisia: does corruption matter?
Authors: Bougatef Khemaies 
Published: January 2017

Purpose
In this paper, the author aims to examine the effect of perceived level of corruption on bank profitability.

Design/methodology/approach
The analysis is based on a balanced panel of ten commercial banks in Tunisia over the period 2003-2014. The author uses the generalized method of moments estimator technique described by Arellano and Bover (1995).

Findings
The author finds a positive relationship between the bank profitability and the corruption level. This surprising result suggests that Tunisian commercial banks take advantage from the high level of corruption. Regarding the others determinants, the findings reveal that bank profitability is positively related to capitalization level and liquidity. By contrast, a low asset quality is associated with low profitability.

Originality/value
The novelty of this study consists in the inclusion of the corruption level as a determinant of bank profitability.

Design/methodology/approach
This paper describes a fire test conducted on a large-scale structure representing four corner bays of a typical multi-storey steel-frame office building.

Findings
A new and unexpected mode of damage occurred.

Originality/value
The test results indicate that an alternate reinforcement detail should be used in combination with unprotected beams.
Experimental study of post-fire performance of high-strength bolts under combined tension and shear
Authors: Kawohl Anne , Lange Jörg 
Published: January 2017

PurposeThis study aims to verify whether the reduction factors for the post-fire performance of Grade 10.9 bolts stated in an earlier study at the TU Darmstadt are also valid for shear and combined tension and shear.Design/methodology/approachTests on Grade 10.9 bolt sets under combined tension and shear were carried out. The tested bolts were heated and cooled without being stressed by an additional mechanical load before being tested.FindingsThe test results show that the reduction factors can also be adopted for bolts under combined tension and shear, but the tension-shear-ratio has an influence on the load bearing capacity.Originality/valueThe post-fire performance of high-strength bolts is of special interest when a building structure is evaluated after an event of fire. In contrast to conventional structural steel, high-strength bolts do not recover their original strength and material properties.
Composite beams under fire loading: numerical modeling of behavior
Authors: Selden Kristi L. , Varma Amit H. 
Published: January 2017

Purpose
The purpose of this study was to develop a three-dimensional (3D) finite element modeling (FEM) technique using the commercially available program ABAQUS to predict the thermal and structural behavior of composite beams under fire loading.

Design/methodology/approach
The model was benchmarked using experimental test data, and it accounts for temperature-dependent material properties, force-slip-temperature relationship for the shear studs and concrete cracking.

Findings
It was determined that composite beams can be modeled with this sequentially coupled thermal-structural 3D FEM to predict the displacement versus bottom flange temperature response and associated composite beam failure modes, including compression failure in the concrete slab, runaway deflection because of yielding of the steel beam or fracture of the shear studs.

Originality/value
The Eurocode stress-strain-temperature (σ-ε-T) material model for structural steel and concrete conservatively predict the composite beam deflections at temperatures above 500°C. Models that use the National Institute of Standards and Technology (NIST) stress-strain-temperature (σ-ε-T) material model more closely match the measured deflection response, as compared to the results using the Eurocode model. However, in some cases, the NIST model underestimates the composite beam deflections at temperatures above 500°C.

Authors: Ozawa Mitsuo , Kim Gyu-Yong , Choe Gyeong-Choel , Yoon Min-Ho , Sato Ryoichi , Rokugo Keitetsu 
Published: January 2017

Purpose
The behavior of high-performance concrete (HPC) at high temperatures is very complex and also affects the global behavior of heated HPC-based structures. Researchers have also reported how various types of fibers affected the mechanical properties of cement-based materials at high temperatures. This study aims to discuss the effects of high temperatures on the compressive strength and elastic modulus of HPC with polypropylene (PP) and jute fiber.

Design/methodology/approach
Adding synthetic fiber (especially the PP type) to HPC is a widely used and effective method of preventing explosive spalling. Although researchers have experimentally determined the permeability of heated PP-fiber-reinforced HPC, few studies have investigated how adding natural fiber such as jute to this type of concrete might prevent spalling. In this study, the effects of high temperatures on the compressive strength and elastic modulus of HPC with PP and jute fiber (jute fiber addition ratio: 0.075 vol.%; length: 12 mm; PP fiber addition ratio: 0.075 vol.%; length: 12 mm) were experimentally investigated.

Findings
The work was intended to clarify the influence of elevated temperatures ranging from 20°C to 500°C on the material mechanical properties of HPC at 80 MPa. HSC with jute fiber showed a compressive strength loss of about 40 per cent at 100°C before recovering to full strength between 200°C and 300°C.

Originality/value
The elastic modulus of high-strength concrete decreased by 10-40 per cent between 100°C and 300°C. At 500°C, the elastic modulus was only 30 per cent of the room temperature value. The thermal expansion strain of all specimens was 0.006 at 500°C.
Fire performance of single plate shear connections in a composite floor
Authors: Selamet Serdar , Bolukbas Caner 
Published: January 2017

Purpose
This paper aims to present a numerical investigation on the fire performance of a single plate shear connection in a steel-framed composite floor. Large-scale fire experiments show that the tensile membrane action of the concrete slab enhances the fire performance of composite floors. The enhancement in the performance is contributed to large slab deflections. However, these deflections cause significant rotations and tensile force in the single plate connection.

Design/methodology/approach
A finite element model is constructed, which consists of a secondary steel beam, concrete slab and shear connection components. The interaction between the connection components such as bolts and single plate is defined by contact surfaces. The analysis is conducted in two uncoupled phases: thermal analysis by creating fire boundaries on the composite floor model with convective and radiative heat transfer, and mechanical analysis by considering thermal expansion and changes in the material stiffness and strength due to temperature.

Findings
The thermo-mechanical analysis of the composite floor finite element model shows that the structure survives the 2-h Standard fire, but the connection fails by bolt shear and buckling of the connection plate.

Originality/value
This paper investigates the fire performance of a shear connection in a steel-framed concrete slab. Previous work generally focused on the concrete slab behavior only. The originality of the research is that the connection is considered as part of a sub-assembly and is subjected to forces due to concrete and steel beam interaction.
Fire performance, including the cooling phase, of structural glued laminated timber beams
Authors: Kinjo H. , Hirashima T. , Yusa S. , Horio T. , Matsumoto T. 
Published: January 2017

Purpose
Based on heating tests and load-bearing fire tests, this paper aims to discuss the charring rate, the temperature distribution in the section and the load-bearing capacity of structural glued laminated timber beams not only during the heating phase during a 1-h standard fire in accordance with ISO 834-1 but also during the cooling phase.

Design/methodology/approach
Heating tests were carried out to confirm the charring rate and the temperature distribution in the cross-section of the beams. Loading tests under fire conditions were carried out to obtain the load-deformation behavior (i.e. the stiffness, maximum load and ductility) of the beam.

Findings
The temperature at the centroid reached approximately 30°C after 1 h and then increased gradually until reaching 110-200°C after 4 h, during the cooling phase. The maximum load of the specimen exposed to a 1-h standard fire was reduced to approximately 30 per cent of that of the specimen at ambient temperature. The maximum load of the specimen exposed to a 1-h standard fire and 3 h of natural cooling in the furnace was reduced to approximately 14 per cent. In case of taking into consideration of the strength reduction at elevated temperature, the reduction ratio of the calculated bending resistance agreed with that of the test results during not only heating phase but also cooling phase.

Originality/value
The results of this study state that it is possible to study on strength reduction in cooling phase for end of heating, timber structural which has not been clarified. It is believed that it is possible to appropriately evaluate the fire performance, including the cooling phase of the timber structural.
