Authors: Mat Nor N.A. , Ismail L. , Jamari S.K.M. , Ramesh K. , Vengadaesvaran B. , Arof A.K. 
Published: November 2014

Purpose
This paper aims to analyse the coating behaviour in corrosion environment as well as to evaluate the best percentage amount of copper oxide and copper needed for organic coating in order to prevent the corrosion degradation. Electrochemical impedance spectroscopy (EIS) studies have been conducted in order to evaluate the corrosion performance of polyester-epoxy-copper oxide and polyester-epoxy-copper coating systems.

Design/methodology/approach
The availability of this modem instruments is used to obtain impedance data as well as computer programs to interpret the results that made the technique popular. In addition, EIS is well suited to the study of polymer-coated metals.

Findings
The results showed that samples containing 25 weight per cent of copper oxide and copper (90P25CuO and 90P25Cu) obtained the excellent corrosion properties from the first day up to 30 days of NaCl immersion. The highest corrosion resistance values obtained by 90P25CuO and 90P25Cu on the 30th day were 7.107 × 108 O and 5.701 × 108 O, respectively, with lower double layer capacitance of 1.407 × 10−9 Farad and 3.935 × 10−9 Farad, respectively. Moreover, the water uptake gained by these two coating samples was the lowest at the end of immersion, which was 0.0084 for 90P25CuO and 0.1592 for 90P25Cu, showing that the sample has good corrosion performance.

Originality/value
This paper discussed on the highest corrosion resistance, double layer capacitance and the water uptake of the copper (Cu) and copper oxide (CuO) coating system obtained from the EIS measurements.

Authors: Chen R. , Lv J. , Feng J. , Liu Y. , Zhang W. 
Published: November 2014

Purpose
The purpose of this paper is to introduce an effective method to discriminate seal inks with Raman microscopy.

Design/methodology/approach
Raman spectra could effectively avoid interference from the paper and give extra peak information in the inks discrimination and identification. Thus, a Renishaw invia confocal Raman microscope system was employed for ink analysis in this study. A total of 12 representative seal ink samples, widely used in seven Chinese provinces, were investigated using the latest model of Renishaw Raman microscope.

Findings
Four types of inks were identified and discriminated successfully. Popular pigments such as Pigment Scarlet Powder, Pigment Yellow 55, phthalocyanine blue, Bronze red C and PbCrO3 were all identified in these seal ink samples. The indicative peaks to identify and discriminate the inks were also summarised and tentatively interpreted.

Research limitations/implications
More ink samples were needed to establish a useful library. Many other pigments used in inks were still unknown.

Practical implications
This method was proved to be fast, accurate and non-destructive, and it could be more easily applied in real cases than Fourier transform infrared spectroscopy.

Originality/value
This method can help scientists discriminate some inks, which can hardly be discriminated by other techniques. The results are useful for the ink analysis and discrimination in forensic (document examination and file source identification), polymer and pigment fields.
Crystal morphology, dispersing stability and dyeing property of the disperse dye based on benzisothiazole
Authors: Li Min , Song Kaili , Xie Kongliang , Hou Aiqin 
Published: November 2014

Purpose
The purpose of this paper is to synthesise a disperse dye based on benzisothiazole and to characterise its crystal morphology, dispersing stability, to study the relationship between the chemical structure and the dyeing property of the dye.

Design/methodology/approach
The disperse dye based on benzisothiazole, 3-(3-methyl-4-N-ethyl-N-benzyl-phenyldiazenyl)-5-nitro-2,1-benzisothiazoles, was synthesized. The disperse dye based on benzisothiazole, 3-(3-methyl-4-N-ethyl-N-benzyl-phenyldiazenyl)-5-nitro-2,1-benzisothiazoles, was synthesised. The chemical structure of the dye obtained was characterised by infrared spectrum Fourier transform infrared spectroscopy and nuclear magnetic resonance (1HNMR), and the crystal morphology was observed by Field Emission Scanning Electron Microscopy. Sodium salt of polycondensated naphthalenesulphonic acid (dispersing agent sodium salt of polycondensated naphthalenesulphonic acid [MF]) and a sulphonated amino polyether (anionic surfactant B600) were employed to grind and disperse the dye crystals. The dispersion property of the dye particles was characterised. Dyeing property of the dispersion system was also studied.

Findings
The dye formed spherical crystals that were made up of a large number of acicular crystals similar to spherical chrysanthemum. The crystals had warping crystal centres inside the spheres. The particle sizes of the dispersion with the mixture of B600 and MF had an uniform distribution and were smaller than that of the dispersion with only single dispersing agent MF. Dyeing with the dispersion system had an excellent reproducibility under alkalinic condition.

Practical implications
An alkalinic dyeing method for poly(ethylene terephthalate) (PET) with disperse dyes as a cleaner wet process had been developed. Such a process combined pretreatment and dyeing process using the alkali-stable disperse dyes and reduced the consumption of water and energy and improved production efficiency.

Originality/value
The crystal morphology, dispersion and dyeing properties of the synthesised disperse dye for dyeing PET fabric under alkalinic condition were discussed. This disperse dye has an important potential application in alkalinic dyeing method.

Authors: Zhang X.R. , Liu L.Z. , Li J.F. , Cui W.W. , Weng L. 
Published: November 2014

Purpose
The key purpose of this study was to investigate the effects of different ultrasonic irradiation times on the wettability and other properties of the resulting water-based coating. The subject water-based coating was prepared using water-soluble polyester and amino resins by ultrasonic oscillation.

Design/methodology/approach
The coating was prepared by polymerising polyester and amino resins in water using ultrasonic oscillation. The coating was baked for 40 seconds at 350°C to coalesce and solidify the film. The contact angle, thermal stability and mechanical properties of the film, as well as the molecular weight (MW) and structure of the polyester resin, were determined.

Findings
The contact angle of the coating was found to decrease with ultrasonic irradiation; the mechanical properties and thermal stability were not altered when the irradiation time was longer than 5 hours. The MW of the polyester initially decreased then increased and stabilized with ultrasonic irradiation. The structure of polyester molecule and aggregated state of the solidified coating were not changed by ultrasonic irradiation.

Research limitations/implications
In the study reported here, the effects of different ultrasonic irradiation times were investigated. Results of this research could benefit in-depth understanding of the influence of ultrasonic treatment on polyester resins and polyester coatings and could further promote the development of water-based coatings.

Originality/value
The contact angle of the water-based coating decreased by mechanical means. The effects of ultrasound on microstructure and properties of the coating and resin were discussed in detail.
High-performance isocyanate-epoxy materials
Authors: Pilawka Ryszard , Goracy Krzysztof , Wilpiszewska Katarzyna 
Published: November 2014

Purpose
The purpose of this paper is to investigate a new group of chemical compounds as accelerators (1-imidazole derivatives – tertiary amines) for curing of isocyanate-epoxy resin matrix. During heating no reaction between epoxy group and active hydrogen in presence 1-substituted imidazole derivatives was reported.

Design/methodology/approach
The influence of accelerator type and content on curing process, thermal stability and chemical structure of hardened resin was determined using temperature modulated differential scanning calorimetry, dynamic mechanical analysis, heat deflection temperature, thermogravimetry (modulated and by activation energy – Ozawa method) and Fourier transform infrared spectroscopy. Additionally, the shear strength of epoxy compositions used as aluminium joints, at ambient and elevated temperature was determined.

Findings
With catalyst content increase the oxazolidone or isocyanurate rings content decreased, indicating enhanced density of cross-linking and thermal resistance. For all imidazole derivatives used (i.e. 1-methylimizadole, 1-ethylimidazole and 1-butylimidazole) accelerating of the curing process was observed (significant decrease of the curing start temperature was reported). The thermal resistance and shear strength was improved with accelerator content (increase of isocyanurate rings amount, and consequently oxazolidone ones).

Originality/value
Introducing of a new group of chemical compounds as new catalysts to isocyanate-epoxy resin material resulted in curing process acceleration, irrespectively of the imidazole derivative type.
The role of faculty autonomy in a course-integrated information literacy program
Authors: Jumonville Anne 
Published: November 2014

Purpose
– The purpose of this paper is to explore the significance of faculty autonomy in sustaining a successful information literacy program.

Design/methodology/approach
– Faculty members were given the opportunity to create courses that integrated and assessed information literacy as part of a course grant program associated with an institutional assessment mandate. This case study analyzes course grant proposals, course assessment methods and results. It also presents results of a follow-up survey of faculty participants to see if they continued to integrate information literacy in other courses. Results are situated in the context of self-determination theory to better understand the role of autonomy in faculty motivation and participation in an assessment program.

Findings
– Defining and integrating information literacy themselves allowed faculty to align information literacy with their own course goals. Supporting faculty in choosing their own assessment methods for these integrations also provided program administrators with new information about faculty members’ teaching and learning practices and values. Results of a follow-up study confirmed that faculty continued to integrate information literacy in their courses of their own accord, underscoring the importance of an autonomy-supportive program structure.

Originality/value
– This paper provides evidence for information literacy advocates that faculty autonomy can be a strength, not an obstacle. It demonstrates ways to incorporate and allow for autonomy within program constraints and introduces librarians to self-determination theory, a way of thinking about motivation that can help librarians pursue more effective collaborations with faculty.

Findings
– Provides information about each source, discusses the characteristics of current scholarship and describes sources that contain unique scholarly contributions and quality reproductions.

Originality/value
– The information may be used by librarians and interested parties as a quick reference to literature on library instruction and information literacy.
Closing the gap
Authors: Totterdill Peter , Exton Rosemary 
Published: November 2014

Purpose
– This paper aims to examine the vast and growing body of evidence which shows that workplace innovation, practices which empower employees to make day-to-day-decisions, challenge established practices and contribute ideas, which are heard at the most senior levels of an organisation lead to better business results as well as enhanced workforce health and engagement.

Design/methodology/approach
– As European businesses struggle to emerge from recession, this evidence offers an important resource for enhanced competitiveness, increasing productivity and the rate of innovation.

Findings
– However, the article also looks at why most businesses are either unaware of this evidence, or that they are unable or unwilling to act on it. Successive surveys demonstrate a substantial gap between research evidence of “what works” and common workplace practice.

Originality/value
– The practical challenge is to build the conditions at European, national and local levels which stimulate, resource and sustain workplace innovation on a large scale. This is vital for European competitiveness as well as for the well-being of Europe’s workers, but it means nothing less than redefining the “common sense” view of the world experienced by managers and others who influence the nature of the workplace. It also implies the creation of a public sphere of shared knowledge and experience, freely available to those instigating or informing change.
State of Knowledge-Intensive Business Services (KIBS) in India
Authors: Joshi Seema 
Published: November 2014

Purpose
– The growing importance of knowledge and innovation in the present era motivated the author to study knowledge-intensive business services (KIBS) in general and the case of India in particular. The purpose of this paper is to track in brief the strength of India’s economy lying in growth of knowledge-intensive services (KIS), which if harnessed properly can lead to its transition to a knowledge economy. More specifically, the paper tries to address two important questions: first, what constitutes KIS and KIBS? And second, how has KIBS been performing in India?

Design/methodology/approach
– The paper makes use of secondary sources of data including various reports, books, journals and statistical tools. An attempt has been made in this paper to review those studies which try to define KIS and KIBS. The data analysis of KIBS in the case of India has been done for the period 2004-2005 to 2011-2012 for which information was available from National Accounts Statistics published by Central Statistical Organization.

Findings
– The paper concludes that no unanimously accepted definition of KIBS has been given so far. In the Indian context it is defined as; “business services include services like computer-related services, R&D, accounting services and legal services and renting of machinery in order of importance (shares) as per India’s National Accounts”. An analysis of performance of KIBS in India shows that among KIBS there are two T-KIBs (with a technology base), namely IT and ITeS, and that R&D services occupy the first and second position in India’s gross domestic product (GDP), originating from business services (KIBS). R&D services registered the highest average annual growth rate followed by computer-related services, renting of machinery, legal services and accounting and auditing services during the seven-year period from 2004-2005 to 2011-2012. However, the compound annual growth rate (CAGR) was highest in the case of R&D services followed by renting of machinery, computer-related services, legal and accountancy and auditing services. KIBS registered a CAGR of 13.04 per cent, which was higher compared to overall GDP growth rate (at 7.36 per cent), and also compared to the CAGR of the real estate and ownership of dwellings and business services segment as a whole (7.62 per cent). Therefore, there is a need to tap the potential of all these KIBS, i.e. knowledge-intense high-tech services (KIHTS) and knowledge-intense marketing services taken in the study through policy initiatives. There is also a need to deal with emerging issues and challenges in KIBS, especially in KIHTS.

Originality/value
– Although there is empirical research on the KIS and KIBS of European Economies, KIBS in India has not received enough research attention. This paper will therefore mainly focus on the performance of KIBS in India.
Comparison of facial predilection sites for cutaneous squamous cell carcinoma and actinic keratosis in Japanese patients
Authors: Shibayama Yoshitsugu , Imafuku Shinichi 
Published: November 2014

AbstractCutaneous squamous cell carcinoma (cSCC) and actinic keratosis (AK) occur most often on the face. Ultraviolet light is apparently their most common cause. As AK is considered to be a precursor of cSCC, their distribution on the face should be similar. However, cSCC often occurs on the temple or mandibular area, whereas AK arises on the central forehead, cheek or nose. We retrospectively evaluated differences in affected site distribution for cSCC (n = 54) and AK (n = 95). We found AK to occur preferentially on the central facial area (63/95, 66%), which is the most sun‐exposed area, and cSCC to occur preferentially on peripheral areas such as the temple and mandibular area (24/54, 44%). Those distributions were significantly different (P = 0.011, Fisher's exact test). This result suggests that cSCC occurs preferentially in the peripheral area compared with the central facial area, which further implies that either other factors are needed to make AK progress to cSCC in peripheral areas, or that peripheral cSCC can occur without preceding AK. This is the first report to focus on geographic assessment of cSCC and AK in detail. Further studies are needed to elucidate the mechanism of our finding.
Velocity model building from seismic reflection data by full‐waveform inversion
Authors: Brossier Romain , Operto Stéphane , Virieux Jean 
Published: November 2014

ABSTRACTFull‐waveform inversion is re‐emerging as a powerful data‐fitting procedure for quantitative seismic imaging of the subsurface from wide‐azimuth seismic data. This method is suitable to build high‐resolution velocity models provided that the targeted area is sampled by both diving waves and reflected waves. However, the conventional formulation of full‐waveform inversion prevents the reconstruction of the small wavenumber components of the velocity model when the subsurface is sampled by reflected waves only. This typically occurs as the depth becomes significant with respect to the length of the receiver array. This study first aims to highlight the limits of the conventional form of full‐waveform inversion when applied to seismic reflection data, through a simple canonical example of seismic imaging and to propose a new inversion workflow that overcomes these limitations. The governing idea is to decompose the subsurface model as a background part, which we seek to update and a singular part that corresponds to some prior knowledge of the reflectivity. Forcing this scale uncoupling in the full‐waveform inversion formalism brings out the transmitted wavepaths that connect the sources and receivers to the reflectors in the sensitivity kernel of the full‐waveform inversion, which is otherwise dominated by the migration impulse responses formed by the correlation of the downgoing direct wavefields coming from the shot and receiver positions. This transmission regime makes full‐waveform inversion amenable to the update of the long‐to‐intermediate wavelengths of the background model from the wide scattering‐angle information. However, we show that this prior knowledge of the reflectivity does not prevent the use of a suitable misfit measurement based on cross‐correlation, to avoid cycle‐skipping issues as well as a suitable inversion domain as the pseudo‐depth domain that allows us to preserve the invariant property of the zero‐offset time. This latter feature is useful to avoid updating the reflectivity information at each non‐linear iteration of the full‐waveform inversion, hence considerably reducing the computational cost of the entire workflow. Prior information of the reflectivity in the full‐waveform inversion formalism, a robust misfit function that prevents cycle‐skipping issues and a suitable inversion domain that preserves the seismic invariant are the three key ingredients that should ensure well‐posedness and computational efficiency of full‐waveform inversion algorithms for seismic reflection data.
Abiotic stress protection by ecologically abundant dimethylsulfoniopropionate and its natural and synthetic derivatives: insights fromBacillus subtilis

Published: November 2014

SummaryDimethylsulfoniopropionate (DMSP) is an abundant osmolyte and anti‐stress compound produced primarily in marine ecosystems. After its release into the environment, microorganisms can exploitDMSPas a source of sulfur and carbon, or accumulate it as an osmoprotectant. However, import systems for this ecophysiologically important compatible solute, and its stress‐protective properties for microorganisms that do not produce it are insufficiently understood. Here we address these questions using a well‐characterized set ofBacillus subtilismutants to chemically profile the influence ofDMSPimport on stress resistance, the osmostress‐adaptive proline pool and on osmotically controlled gene expression. We included in this study the naturally occurring selenium analogue ofDMSP, dimethylseleniopropionate (DMSeP), as well as a set of syntheticDMSPderivatives. We found thatDMSPis not a nutrient forB. subtilis, but it serves as an excellent stress protectant against challenges conferred by sustained high salinity or lasting extremes in both low and high growth temperatures.DMSePand syntheticDMSPderivatives retain part of these stress protective attributes, butDMSPis clearly the more effective stress protectant. We identified the promiscuous and widely distributedABCtransporterOpuCas a high‐affinity uptake system not only forDMSP, but also for its natural and synthetic derivatives.

SummaryOyster diseases caused by pathogenic vibrios pose a major challenge to the sustainability of oyster farming. In France, since 2012 a disease affecting specifically adult oysters has been associated with the presence of Vibrio aestuarianus. Here, by combining genome comparison, phylogenetic analyses and high‐throughput infections of strains isolated before or during the recent outbreaks, we show that virulent strains cluster into two V. aestuarianus lineages independently of the sampling dates. The bacterial lethal dose was not different between strains isolated before or after 2012. Hence, the emergence of a new highly virulent clonal strain is unlikely. Each lineage comprises nearly identical strains, the majority of them being virulent, suggesting that within these phylogenetically coherent virulent lineages a few strains have lost their pathogenicity. Comparative genomics allowed the identification of a single frameshift in a non‐virulent strain. This mutation affects the varS gene that codes for a signal transduction histidine‐protein kinase. Genetic analyses confirmed that varS is necessary for infection of oysters and for a secreted metalloprotease expression. For the first time in a Vibrio species, we show here that VarS is a key factor of pathogenicity.
