Job analysis of academic librarians in Greece
Authors: Mouza Anna Maria , Grigoriadou Sofia P. 
Published: March 2016

Purpose
– The purpose of this paper is to identify the obligations and responsibilities of librarians, working in Greek academic libraries and to investigate whether there are significant differences among various institutions.

Design/methodology/approach
– The survey was based on a questionnaire containing 161 duties performed by academic librarians, classified into five main categories which are: general management, collection management, materials organization, user service and system management. The respondents were 31 managers at Greek academic libraries, who were asked to assess their duties according to importance, difficulty and frequency, and whether such tasks were deemed professional, para-professional or non-professional. A two-way ANOVA was applied to determine whether performed duties significantly differed according to institution size and/or type.

Findings
– The results revealed no significant differences regarding importance of duties while many differences were detected across all main categories regarding difficulty. Differences were also recorded concerning the frequency of duties for some of the subcategories under general and collection management, materials organization and the subcategory cultural events and programs. Finally, professional duties represented 86 percent of total duties, indicating the necessity of professional librarians for the effective management of their responsibilities.

Originality/value
– These findings, which are first recorded in Greece and refer to academic librarians’ duties, will be particularly useful for decision makers to reach the right decisions regarding the implementation of human resource practices, taking into account the individuality of the institutions under consideration. Also these outcomes can be viewed as a valuable guide for adapting the indicated decisions under the rapidly introduced technological changes and properly tackling problems stemming from the economic recession.
CEO power and CEO hubris: a prelude to financial misreporting?
Authors: Cormier Denis , Lapointe-Antunes Pascale , Magnan Michel 
Published: March 2016

Purpose– The purpose of this paper is to explore how the tension between a firm’s CEO power features and externally observable hubris attributes may determine the likelihood of financial misreporting.Design/methodology/approach– The analyses are based on a sample of 16 Canadian firms for which there were formal accusations of financial reporting fraud filed by securities regulators, assorted with regulatory sanctions; as well as 16 firms matched on industry and size with no evidence of financial misreporting.Findings– The findings suggest that firms accused of financial misreporting exhibit features of strong CEO power and hubris as reflected in their relations with the self, others and the world. Governance mechanisms do not seem to be effective in detecting or preventing financial misreporting, with independent boards of directors proving especially ineffectual.Social implications– The findings suggest that formal governance processes may get coopted by a CEO with hubristic tendencies.Originality/value– While the tentative model is more explanatory than predictive, it opens up a new research area as it brings the concept of hubris into accounting research.

Published: March 2016

In this article, the heat transferring property of the copper-water nanofluids in self-exciting mode oscillating flow heat pipe under different laser heating power is experimented, as well as is compared with that of the distilled water medium in self-exciting mode oscillating flow heat pipe under same heating condition. The objective of this article is to provide the heat transfer characteristics of Cu-H2O nanofluids in self-exciting mode oscillating-flow heat pipe under different laser heating input, and to compare with the heat transfer characteristics of the same heat pipe with distilled water as working fluids.
The SEMOS HP used in this experiment is made of brass tube with 2mm interior diameter, which is consisted of 8 straight tubes with 4 turns’ evaporation section and 12 turns’ condensation section. The heat resource for the evaporation zone is eight channel quantum pitfall diode array semi-conductor laser heater with 940nm radiation wave length, while the radiation power of each channel is changeable within 0–50W and the facular size is 1×30mm2. The condensation section is set in a cooling water tank in which water is from another higher tank. The actual transferring rate could be calculated by the flow rate of the cooling water and the change of the temperature. The change of the temperature of the heat pipe wall is measured by those thermo-couple fixed in different section in the heat pipe and data is collected by a data acquisition. In the heat pipe the fluid filling rate is 43%, the pressure is 2.5×10−3Pa, and the heat pipe inclination angle is 55° while the size of the brass particle in the nanofluids is less than 60nm and volume proportion is 0.5%.
In this paper, the particularity of heat transfer rate of the SEMOS heat pipe with Cu-H2O fluid has been experimentally confirmed by changing the proportion of working fluid and Cu nonsocial particles in the heat pipe. By comparing the experimental result of these two different medium in the SEMOS HP, it is shown that the heat transferring rate with brass-water nanofluids as medium is much better than that with distilled water as medium under same volume proportion.

In recent years, with the social progress and the rising of living standard, people have realized the importance of clean air. Microscale or nanometer photocatalyst has a certain application advantages in the purification of pollutants. Nano-TiO2 is one of novel promising environmental-friendly catalytic materials. However, the, only can absorb ultraviolet irradiation which accounts little in sunlight. Co-doping is beneficial in modifying TiO2. The synergistic action of dopants not only increased the activity of photocatalytic degradation, but also expanded the response range of light to the visible light region.
Ceramic tile is a kind of common building material, and has broad application to the outside and inside wall of buildings for decoration. If we carry nanometer TiO2on ceramic tiles, they can clear pollutants in indoor and outdoor air.
In this study, we prepared a TiO2 photocatalytic gel in advance by doping amount of N, F and/or Fe. Then we coated the gel on a kind of ceramic tile. After calcination we prepared a special ceramic tile with TiO2. The TiO2 was co-doped with N, F and Fe elements. The photo-catalytic activities of the ceramic tile samples under visible light irradiation were evaluated by the degradation of methylene blue solution. The result showed that the photocatalytic activity of the ceramic tile co-doped with TiO2 doped with 4wt % N, 0.06 wt% Fe, 0 wt% F, calcinated at 500°C, was the highest. The influence order of the factors was calcination temperature >Fe >F> N.
Thermal Wave Model for Analysis of Multilayer Tissue Medium in Presence of Inhomogeneity in Laser Tissue Treatment
Authors: Verma A. K. , Mahapatra S. K. 
Published: March 2016

In this current investigation a modified model of Pennes Bioheat equation i.e. the thermal wave model of bioheat transfer (TWMBT) is applied for the heat transfer processes underlying the laser tissue interaction to investigate the thermal damage of biological tissues.
For analysing the thermal effect, a two dimensional domain is taken with three layers (simulating human skin) of different thermal properties with inhomogeneity in the middle layer. The inhomogeneity considered in this problem simulates the presence of tumor inside tissue medium. The finite volume method (FVM) is used for discretization. The central difference scheme is adapted for discretizing the spatial term. The incident collimated beam on the top layer is provided to destroy the unwanted tumor cell represented by inhomogeneity in the middle layer. Subsequent to the discretization of governing equation of hyperbolic nature, implicit scheme has been employed to obtain the solution and its stability has been assessed. As per the findings, the hyperbolic thermal wave model is more appropriate than the Pennes model of bioheat transfer for laser-tissue treatment.
A Microstructure-Based Monte Carlo Investigation on the Anisotropic Radiative Transfer in Porous Ceramics
Authors: Wang B. X. , Zhao C. Y. 
Published: March 2016

Thermal barrier coatings provide excellent thermal insulation for metal components of gas turbines. Although the relationships between microstructures and mechanical properties as well as thermal conductivity of various TBCs have been extensively studied, there still exists a deficiency of a full understanding on microstructural-related thermal radiation transport inside them, which becomes more and more crucial for advanced gas turbine applications requiring higher operating temperatures. This study aims at presenting a microstructure-based numerical investigation on radiative transfer in the air plasma sprayed (APS) TBC.
In this study, the microstructures of APS TBCs are quantitatively reconstructed based on the Ultra-Small-Angle X-Ray Scattering (USAXS) measurement by the Stony Brook University group, in which the microscale interlamellar pores, intrasplat cracks and globular voids are regarded as oblate spheroids with different sizes and aspect ratios, with a specific distribution of orientations. This is a typical anisotropic medium, in which the physical properties vary with the observing direction. The anisotropic feature of radiative properties including the scattering coefficient and phase function is for the first time demonstrated using the discrete dipole approximation (DDA) method. A modified Monte Carlo method is proposed and implemented to solve the anisotropic radiative transfer problem in such medium. The spectral normal-hemispherical reflectance and transmittance of the coating are thus obtained and further compared with the experimental data from literature as well as our group to validate this numerical method. This work provides a versatile numerical framework for the study of the anisotropic radiative transfer mechanism in APS thermal barrier coatings based on microstructure charaterization.
Enhanced Nucleate Pool Boiling From Microstructured Surfaces Fabricated by Selective Laser Melting
Authors: Ho Jin Yao , Wong Kin Keong , Leong Kai Choong , Yang Chun 
Published: March 2016

Selective laser melting (SLM) is a promising manufacturing method which enables the production of complex structured components from base metal powders. With the development of SLM, the possibility of fabricating functional heat transfer devices such as heat pipes and heat sinks using this technique has also gained significant interest in the recent years. In this paper, the possibilities of producing microstructured surfaces using SLM to promote nucleate pool boiling heat transfer were explored. The SLM facility (SLM 250 HL by SLM Solutions GmbH) at the Future of Manufacturing Laboratory 1 of Singapore Centre for 3D Printing (SC3DP) in Nanyang Technological University (NTU), Singapore was employed for the fabrication of the surfaces. The machine is comprised of a Gaussian distributed Yb:YAG laser with maximum power of 400 W and laser beam spot size of 80 μm which melts and fuses the AlSi10Mg base powder of distribution size 20 μm to 63 μm layer-by-layer to develop three-dimensional structures.
In total, four 1 cm × 1 cm microstructured surfaces were produced; namely micro-cavity surface, micro-fin surface, micro-sized rectangular channel (MRC) surface and micro-sized square channel (MSC) surface. Saturated pool boiling experiments were conducted on these surfaces in a water-cooled thermosyphon with FC-72 as the coolant fluid under atmospheric condition. In comparison with a plain surface, the MRC and MSC surfaces exhibited marginal improvements in the average heat transfer coefficient whilst more significant enhancements of up to 51.2% were demonstrated with the micro-cavity and micro-fin surfaces. At low heat fluxes (< 7 W/cm2), minimal differences in heat transfer performances between the microstructured surfaces and plain surface were observed. For increased heat fluxes, incremental enhancements in the heat transfer coefficients were observed for the micro-cavity and micro-fin surfaces as compared to the plain surface. The highest enhancement in the heat transfer coefficient over the plain surface was determined to be 63.5% for the micro-fin surface at the heat flux of 17.9 W/cm2 and it was also observed that the heat transfer coefficient of micro-fin surface is consistently higher that of other microstructured surfaces for the range of heat fluxes tested. In addition, higher critical heat fluxes were also achieved with all microstructured surfaces as compared to the plain surface with the highest CHF of 46.2 W/cm2 for the micro-fin and MRC surface. Visual observations suggest that the enhancement in heat transfer from the microstructured surfaces is likely to be due to the increased bubble nucleation sites created from the extended surfaces and the artificial cavities. In summary, these results indicate the promising use of SLM to produce surface features that will enhance pool boiling heat transfer.
Experimental and Numerical Studies of Fluid Flow Confined in Microchannel
Authors: Wang Yan , Ling Xiang 
Published: March 2016

The heat transfer performance of fluid flowing in a microchannel was experimentally studied, to meet the requirement of extremely high heat flux removal of microelectronic devices. There were 10 parallel microchannels with rectangular cross-section in the stainless steel plate, which was covered by a glass plate to observe the fluid flowing behavior, and another heating plate made of aluminum alloy was positioned behind the microchannel. Single phase heat transfer and fluid flow downstream the microchannel experiments were conducted with both deionized water and ethanol. Besides experiments, numerical models were also set up to make a comparison with experimental results.
It is found that the pressure drop increases rapidly with enlarging Reynolds number (200), especially for ethanol. With comparison, the flow resistance of pure water is smaller than ethanol. Results also show that the friction factor decreases with Reynolds number smaller than the critical value, while increases the velocity, the friction factor would like to keep little changed. We also find that the water friction factors obtained by CFD simulations in parallel microchannels are much larger than experiment results.
With heat flux added to the fluid, the heat transfer performance can be enhanced with larger Re number and the temperature rise could be weaken. Compared against ethanol, water performed much better for heat removal. However, with intensive heat flux, both water and ethanol couldn’t meet the requirement and the temperature at outlet would increase remarkably, extremely for ethanol. These findings would be helpful for thermal management design and optimization.

ABSTRACT

Candida glabrata
isolates have reduced
in vitro
susceptibility to azoles, which raises concerns about the clinical effectiveness of fluconazole for treating bloodstream infection (BSI) by this
Candida
species. We aimed to evaluate whether the choice of initial antifungal treatment (fluconazole versus echinocandins or liposomal amphotericin B [L-AmB]-based regimens) has an impact on the outcome of
C. glabrata
BSI. We analyzed data from a prospective, multicenter, population-based surveillance program on candidemia conducted in 5 metropolitan areas of Spain (May 2010 to April 2011). Adult patients with an episode of
C. glabrata
BSI were included. The main outcomes were 14-day mortality and treatment failure (14-day mortality and/or persistent
C. glabrata
BSI for ≥48 h despite antifungal initiation). The impact of using fluconazole as initial antifungal treatment on the patients' prognosis was assessed by logistic regression analysis with the addition of a propensity score approach. A total of 94 patients with
C. glabrata
BSI were identified. Of these, 34 had received fluconazole and 35 had received an echinocandin/L-AmB-based regimen. Patients in the echinocandin/L-AmB group had poorer baseline clinical status than did those in the fluconazole group. Patients in the fluconazole group were more frequently (55.9% versus 28.6%) and much earlier (median time, 3 versus 7 days) switched to another antifungal regimen. Overall, 14-day mortality was 13% (9/69) and treatment failure 34.8% (24/69), with no significant differences between the groups. On multivariate analysis, after adjusting for baseline characteristics by propensity score, fluconazole use was not associated with an unfavorable evolution (adjusted odds ratio [OR] for 14-day mortality, 1.16, with 95% confidence interval [CI] of 0.22 to 6.17; adjusted OR for treatment failure, 0.83, with 95% CI of 0.27 to 2.61). In conclusion, initial fluconazole treatment was not associated with a poorer outcome than that obtained with echinocandins/L-AmB regimens in patients with
C. glabrata
BSI. (This study has been registered at ClinicalTrials.gov under registration no. NCT01236261.)

ABSTRACT

This annex study to a phase 1 study aimed to correlate urinary concentrations and bactericidal titers (UBTs) of BAL30072, a novel siderophore monosulfactam, in healthy subjects in order to evaluate which dosage of BAL30072 should be investigated in a clinical study on complicated urinary tract infection (UTI). Three cohorts of a total of 19 healthy male subjects were included in the add-on study and received the following BAL30072 dosages. The 1st cohort received 1 g once a day (q.d.) intravenously (i.v.) (1 h) on day 1 and 1 g thrice daily (t.i.d.) on day 2, the 2nd cohort received 2 g q.d. i.v. (1 h) on day 1 and 2 g t.i.d. on day 2, and the 3rd cohort received 1 g q.d. i.v. (4-h infusion) on day 8. Urine was collected up to 24 h after drug administration. UBTs were determined for seven
Escherichia coli
isolates (three wild type [WT], CTX-M-15, TEM-3, TEM-5, NDM-1), two
Klebsiella pneumoniae
isolates (WT, KPC), one
Proteus mirabilis
isolate (WT), and two
Pseudomonas aeruginosa
isolates (WT, VIM-1 plus AmpC). Urine drug concentrations were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The median urinary excretions of BAL30072 ranged between 38% and 46% (3 cohorts). The median UBTs after i.v. administration of 1 or 2 g q.d. and after 1 or 2 g t.i.d. showed positive UBTs for 24 h after the lowest dosage (1 g q.d.) for 5 of 7 of the
Enterobacteriaceae
strains and after the higher dosage of 2 g administered i.v. t.i.d. for all strains tested. After i.v. infusion of 1 g over 4 h, positive UBTs were demonstrated for three
E. coli
strains for up to 12 h, for the
K. pneumoniae
(KPC) strain for up to 8 h, and for the
P. aeruginosa
(VIM-1 plus AmpC) strain for up to only 4 h. The minimal bactericidal concentrations (MBCs) of the
E. coli
(NDM-1) strain and the
K. pneumoniae
(WT) strain correlated well between broth and urine but did not correlate well for the two
P. aeruginosa
strains. BAL30072 exhibits positive UBTs for 24 h even after a dosage of 1 g administered i.v. q.d. for 5 of 7
Enterobacteriaceae
strains and after 2 g administered i.v. t.i.d. for all strains except one
P. aeruginosa
strain (50% of the time). In general, the UBTs correlated well with the MICs of the
Enterobacteriaceae
but were lower for
P. aeruginosa
. The clinical efficacy with a dosage regimen of BAL30072 of 2 g administered i.v. t.i.d. should be evaluated in the treatment of complicated UTI.
