Potential Risk Comparison of Formaldehyde and Acetaldehyde Exposures in Office and Gasoline Station Workers

Assessment of exposures of formaldehyde and acetaldehyde that related to urinary biomarkers among office and gasoline station workers was conducted. Our results revealed that the evaluation of ambient air formaldehyde and acetaldehyde in official were significantly higher than in gasoline stations; 28.72 to 11.31 µg m -3 and 7.85 to 3.34 µg m -3 respectively (independence t-test, p<0.01). The sum average lifetime cancer risk of official and gasoline stations workers exposure to formaldehyde and acetaldehyde were determined as the values of 2.51E-05 and 1.30E-05, which were higher than an acceptable criteria defined as 1.00 x 10 -6 . For non-cancer health effects, sum of the hazard quotients (hazard index, HI) of exposures to these two substances in office and gasoline station workers were found at the ratio of 0.40 and 0.21. Both HIs were lower than minimal level which indicated that there is no risk of other health effects. Ambient air formaldehyde was strongly and significantly correlated to ambient air acetaldehyde (r=0.907, p<0.01) as well as urinary formaldehyde was significantly correlated to urinary acetaldehyde (r=0.498, p<0.01). Urinary formaldehyde did not show correlation to ambient air formaldehyde but urinary acetaldehyde was significantly correlated to ambient air acetaldehyde (r=0.429, p<0.01). In addition, urinary formic acid was not related to any exposures. Results of this study supported that urinary acetaldehyde may be used as biomarkers for bio- monitoring in human exposures.
HOMOGENIZATION OF MAGNETO-ELECTRO-ELASTIC MULTILAMINATED MATERIALS

Summary In this work, based on the periodic unfolding homogenization technique, the limiting equations modelling the behaviour of three-dimensional magneto-electro-elastic periodic structures are rigorously established. The local problems and the corresponding homogenized coefficients of the elastic, dielectric, magnetic permittivity, piezoelectric, piezomagnetic and magneto-electric (ME) tensors are explicitly described. The homogenization model is exemplified for laminated composites and a unified general formula for all effective properties of periodic multilaminated magneto-electro-elastic composites is obtained. This formula is applied to investigate the global behaviour for the important case of transversely isotropic constituents and any finite number of layers in each periodic cell. Examples that provide theoretical evidence of the presence of both a product property and the ME effect are given.
Emotional mediators of psychological capital on well-being: The role of stress, anxiety, and depression

Article history: Received October 1, 2012 Received in revised format 22 January 2013 Accepted 23 January 2013 Available online January 25 2013 Researchers have tried to investigate multiple factors affecting employees' social, emotional, and psychological well-being. In this study particularly, nurses' emotional and psychological well-being is considered. Of most important factors affecting well-being in place of work has known to be busy work and stress, constructive and destructive emotions, and psychological capital. Present study considered to test a developed model of psychological capital, constructive and destructive emotions, stress, anxiety, and depression as antecedents of wellbeing. 296 nurses took part in the survey, using path analysis method hypotheses were tested, and the proposed model was evaluated. Results indicated that nurses' high psychological capital increases their constructive emotions, reduces destructive emotions and eventually increase their well-being. The role of destructive emotions was more prominent in increasing wellbeing as well. Furthermore, stress had an incremental influence on well-being. In general, research results emphasize the need for more attention to the components of psychological capital, and intervention and coping strategies. The conclusions of a more detailed is that to improve nurses' well-being the more emphasize should be on decreasing destructive emotions than increasing constructive ones. In addition, keeping an optimal level of stress is necessary for good functioning and improvement of overall well-being. © 2013 Growing Science Ltd. All rights reserved.
Finite strain has no influence on the illite crystallinity of tectonized Eocene limestone breccias of the Morcles nappe, Swiss Alps

Abstract The relationship between illite crystallinity (IC) and finite strain as well as lattice strain and crystallite size of illite is examined in a series of 27 deformed breccia samples from the inverted limb of the Morcles nappe. The IC is determined independently for limestone components and a red/green clay-silt matrix. The finite strain varies widely (D = 0.8 - 2.5). The IC values vary from diagenetic to epizonal, but no correlation with finite strain could be established. The spread of IC values is explained by heterogeneities within the protolith which have not been homogenized/ obliterated by the anchizonal to epizonal metamorphic overprint. While limestone pebbles display IC values in agreement with the regional metamorphic conditions, the clay-silt matrix has anomalously high IC values, even after deconvolution of the 10 Å peak to correct for the presence of paragonite/ muscovite. No correlation could be established between finite strain, lattice strain and/or crystallite size of illite.
Study of methane oxidation over alumina supported Pd–Pt catalysts using operando DRIFTS/MS and in situ XAS techniques

Graphical Abstract Abstract Methane oxidation over Pd–Pt/ model catalysts calcined at three different conditions is investigated using operando diffuse reflectance infrared Fourier transform spectroscopy and mass spectrometry, and in situ X-ray absorption spectroscopy while cycling the feed gas stoichiometry between lean (net-oxidising) and rich (net-reducing) conditions. When calcined in air, alloy Pd–Pt nanoparticles are present only on catalysts subjected to elevated temperature () whereas calcination at lower temperature (500 ) leads to segregated Pt and Pd nanoparticles on the support. Here, we show that the alloy Pd–Pt nanoparticles undergo reversible changes in surface structure and composition during transient methane oxidation exposing a PdO surface during lean conditions and a metallic Pd–Pt surface (Pd enriched) under rich conditions. Alloyed particles seem more active for methane oxidation than their monometallic counterparts and, furthermore, an increased activity for methane oxidation is clearly observed under lean conditions when PdO has developed on the surface, analogous to monometallic Pd catalysts. Upon introducing rich conditions, partial oxidation of methane dominates over total oxidation forming adsorbed carbonyls on the noble metal particles. The carbonyl spectra for the three samples show clear differences originating from different surfaces exposed by alloyed vs. non-alloyed particles. The kinetics of the noble metal oxidation and reduction processes as well as carbonyl formation during transient methane oxidation are discussed.
On fluid motion in librating ellipsoids with moderate equatorial eccentricity

The motion of a homogeneous fluid of viscosity ν confined in a librating ellipsoidal cavity with semi-axes a and moderate equatorial eccentricity is investigated. The ellipsoid rotates with an angular velocity Ω0(1 + δsint), where Ω0 is the mean rate of rotation, is the libration frequency and Ω0δ represents the amplitude of longitudinal libration. When δ ≪2 and E1/2 ≪ 2 ≪ 1, where E is the Ekman number defined as E = ν/(a2Ω0), an explicit analytical solution describing fluid motion in librating ellipsoids is derived for any size of the libration frequency . Three-dimensional numerical simulations of the same problem are also performed, revealing the generation of mean zonal flow in librating ellipsoidal cavities and showing a satisfactory agreement between the asymptotic and numerical analyses.
ADOPTION OF INTERNET BANKING: THEORY OF THE DIFFUSION OF INNOVATION

The innovation diffusion theory (IDT) could be considered as one of the earliest theories that attempts to explore factors that influence an individual to adopt an innovation or a new technology. The theory suggests five key beliefs that influence the adoption of any innovation: relative advantage, complexity, compatibility, trialability, and observability. The purpose of this study was to test part of IDT’s attributes empirically. We used Internet banking as the innovation or the targeted technology. We surveyed 1164 business and MBA students in four public universities in Malaysia. Structural equation modelling was used to analyse the data. The results showed that relative advantage, compatibility, and trialability have a significant effect on att itude. Consequently, attitude significantly aff ects the intention to use Internet banking. Based on the findings, implications to practice are offered
Car Setup Optimization Using Multi-Objective Swarm Algorithms

In this paper, we propose to use two multi-objective swarm optimization algorithms, called MOPSO-CDR and MOABC, to tackle the car setup optimization problem. We aim to find the best set of parameters for the car in order to improve its performance during the races. We used The Open Racing Car Simulator (TORCS) in our simulations and we compared our results to the ones presented in the 2010 Car Setup Optimization Competition. We demonstrated that the MOABC can achieve similar results when compared to the state-of-art algorihms. The MOPSO-CDR outperformed all the previous approaches, including the MOABC algorithm for this problem.
DUST-CORRECTED STAR FORMATION RATES OF GALAXIES. II. COMBINATIONS OF ULTRAVIOLET AND INFRARED TRACERS

We present new calibrations of far-ultraviolet (FUV) attenuation as derived from the total infrared to FUV luminosity ratio (IRX) and the FUV–near-UV(NUV) color. We find that the IRX-corrected FUV luminosities are tightly and linearly correlated with the attenuation-corrected Hα luminosities (as measured from the Balmer decrement), with an rms scatter of ±0.09 dex. The ratios of these attenuation-corrected FUV to Hα luminosities are consistent with evolutionary synthesis model predictions, assuming a constant star formation rate over 100 Myr, solar metallicity, and either a Salpeter or a Kroupa initial mass function with lower and upper mass limits of 0.1 and 100 M☉. The IRX-corrected FUV to Balmer-corrected Hα luminosity ratios do not show any trend with other galactic properties over the ranges covered by our sample objects. In contrast, FUV attenuation derived from the FUV–NUV color (UV spectral slope) show much larger random and systematic uncertainties. When compared to either Balmer-corrected Hα luminosities or IRX-corrected FUV luminosities the color-corrected FUV luminosities show ∼2.5 times larger rms scatter, and systematic nonlinear deviations as functions of luminosity and other parameters. Linear combinations of 25 μm and 1.4 GHz radio continuum luminosities with the observed FUV luminosities are also well correlated with the Balmer-corrected Hα luminosities. These results provide useful prescriptions for deriving attenuation-corrected star formation rates of galaxies based on linear combinations of UV and IR or radio luminosities, which are presented in convenient tabular form. Comparisons of our calibrations with attenuation corrections in the literature and with dust attenuation laws are also made.
Risk assessments at the Royal Netherlands Air Force: an explorative study

In this paper, differences in the assessment of mission risks and mission benefits between operators and members of the management level in the transport helicopter branch of the Royal Netherlands Air Force (RNLAF) are studied. Results were obtained from a risk analysis that was conducted in accordance with RNLAF procedures. The analysis suggests that the two organizational levels have a coherent perception on risks despite their hierarchical position. Perceived measures of control – controllability – seem to induce the inclusion or the exclusion of what is appeared to be a risk. The analysis also suggests that risk management tools may obscure these perceptual differences. Risk management tools may therefore not be sufficient to attain safe operations. In discussions and future studies on risk management and on hierarchical differences in risk perception, this is something to take well notice of. Also, managers and others involved in risk management need to recognize the implications of using risk management instruments that are based on simplified models of risk. This research adds to the risk management theory because it connects multi-dimensional risk theory with actual organizational risk management practice.
Medicinal plants, chemical composition and quality: may blackcurrant buds and blackberry sprouts be a new polyphenol source for herbal preparations?

It is well known that plants are important sources for the preparation of natural remedies as they contain many biologically active compounds: in particular, phenolic compounds are one of the most widely occurring groups of phytochemicals. Some endemic species may be used for the production of herbal preparations containing phytochemicals with significant antioxidant capacities and health benefits: blackberry sprouts and blackcurrant buds are known to contain appreciable levels of phenolic compounds, including flavonols, phenolic acids and catechins. The aim of this research was to perform an analytical study of blackcurrant and blackberry bud-preparations, in order to identify the main bioactive polyphenolic compounds, to study the total polyphenolic content and to obtain a specific profile of the main polyphenols contained in these products using a High Performance Liquid Chromatograph − Diode Array Detector; the same analyses were performed both on the University lab preparations and on commercial preparations. Different chromatographic methods were used to determine concentrations of phytochemical compounds in the preparations, allowing for quantification of statistically significant differences in their polyphenolic content both in the case of Ribes nigrum and Rubus ulmifolius. The assessment of chemical composition and bioactivities of the plant-derived products could help in find out new sources of natural antioxidants and other health-promoting compounds: only with the deep knowledge of the bioactive composition of plant preparations it will be possible to develop a new generation of standardized, effect-optimized, monoand multi-extract preparations.
Can China Continue Feeding Itself? The Impact of Climate Change on Agriculture

Several studies addressing the supply and demand for food in China suggest that the nation can largely meet its needs in the coming decades. However, these studies do not consider the effects of climate change. This paper examines whether near future expected changes in climate are likely to alter this picture. The authors analyze the effect of temperature and precipitation on net crop revenues using a cross section consisting of both rainfed and irrigated farms. Based on survey data from 8,405 households across 28 provinces, the results of the Ricardian analysis demonstrate that global warming is likely to be harmful to China but the impacts are likely to be very different in each region. The mid latitude region of China may benefit from warming but the southern and northern regions are likely to be damaged by warming. More precipitation is beneficial to Chinese farmers except in the wet southeast. Irrigated and rainfed farmers have similar responses to precipitation but not to temperature. Warmer temperatures may benefit irrigated farms but they are likely to harm rainfed farms. Finally, seasonal effects vary and are offsetting. Although we were able to measure the direct effect of precipitation and temperature, we could not capture the effects of change in water flow which will be very important in China. Can China continue feeding itself if climate changes? Based on the empirical results, the likely gains realized by some farmers will nearly offset the losses that will occur to other farmers in China. If future climate scenarios lead to significant reductions in water, there may be large damages not addressed in this study.
Determination of Transit Service Accessibility Standard for Intercity Bus Passengers

Intercity bus terminals function as transit facilities that tend to be less effective. Intercity bus passengers prefer to transit outside the terminal. The connectivity factor is consideration of the passengers’ needs (Abdullah et al., 2018), one of its indicators is accessibility to or from the transit location. At present, there is no standard for a convenient transit location distance for passengers from the place of origin or to a destination in the city. The criteria are compiled into the passenger transit level of service (LOS), as an effective tool to evaluate the quality of the location based on passengers’ perceptions with the scales LOS A (Very Near), LOS B (Near), LOS C (Rather Close), LOS D (A Little Far), LOS E (Far) and, LOS F (Very Far). The research and case study were conducted in Makassar city. The data were obtained through questionnaires. Law Successive interval scaling and regression were used as the methods of analysis. The results of the research indicate that the transit distances expected by passengers were as follows: LOS A-B is<2 km and LOS C is 2,1-4 km , LOS D is 4,1-12 km, LOS E is 12,1-20 km and, LOS F is >20 km. Moreover, the distances of the transit location from roads were as follows: LOS A-B is < 100m, LOS C is 1001000m, LOS D is 1001-2000 m, LOS E is 2001-2400m and LOS F is >2400 m.
Purification and Characterization of a Polygalacturonase Produced by Wickerhamomyces anomalus

The aim of this work was to study the purification and physicochemical properties of an endo-polygalacturonase (PG) produced by Wickerhamomyces anomalus isolated from the citrus fruit peels. The enzyme was purified to homogeneity from the culture filtrate of W. anomalus grown on the yeast nitrogen base medium with glucose as carbon and energy source and citrus pectin as inductor. After anion-exchange chromatography and gel filtration chromatography, PG activity was eluted as a single peak, yielding 21% of the original activity. After dialysis and cation-exchange chromatography, only one fraction with PG activity was obtained, recovering 56% of initial enzyme activity and 1.3-fold increase in specific activity. The molecular weight of the enzyme was estimated as 43 kDa by the SDS-PAGE. The enzyme exhibited maximal activity at pH 4.2 and was stable over a pH range from 3.5 to 6.0 and up to 49oC for 10 h. The Vmaxand Km values with polygalacturonic acid as substrate were 0.26 mmol/L.min and 0.173 mg/mL, respectively. Cations such as Cu+2, Fe+3, Mg+2, Mn+2 and Zn+2 did not show any significant effect on PG activity but K+ and Ca+2 reduced it. The purified PG was able to macerate cassava tissues.
Role of Emotional Intelligence on the Relationship among Leadership Styles, Decision Making Styles and Organizational Performance: A Review

This paper constructs a conceptual model to study the impact of emotional intelligence on the relationship among leadership styles, decision making styles and organizational performance. Study also give the brief review of emotional intelligence, leadership styles and the relationship among leadership styles, emotional intelligence and other studied variables. The paper has conceptual based theoretical evidences to support the model. Research findings of the previous literature supports the idea that emotional intelligence moderates the relationship among leadership styles and decision making styles as emotional intelligence strongly associated with leadership styles and decision making styles. Emotional intelligence also moderates the relationship between leadership styles and organizational performance. Study further founds that decision making styles have an effect on organizational performance.
Life cycle, population structure and vertical distribution of Metridia spp. (Copepoda: Calanoida) in the Oyashio region (NW Pacific Ocean)

Vertical distribution and population structure of Metridia pacifica and M. okhotensis were investigated at Site H in the Oyashio region (western subarctic Pacific) to evaluate their life cycle modes. Although recruitment of M. pacifica continued throughout the year in the top 250 m of the water column, 2 pronounced generations were recognized. The first generation was character- ized by rapid development during the spring phytoplankton bloom (generation length: 2-3 mo), and the second by slow development (generation length: 9-10 mo) with overwintering at Stage 5 in deeper-layers (up to 1000-2000 m). In contrast, M. okhotensis was consistently found at depth (250-1000 m) throughout the year, except for excursions to the subsurface layer for spawning during the phytoplankton bloom. Developmental sequences of M. okhotensis could not be resolved very clearly, largely because of extremely low abundance of Copepodite Stages 2 and 3 (C2-C3). As a ten- tative life cycle scenario, the C1 produced during one year was considered to overwinter and develop to C5 through the phytoplankton bloom of the next year. These C5 overwinter and molt to C6 and reproduce during the phytoplankton bloom of the following year. Thus, the generation length of M. okhotensis is estimated as 2 yr. For both species, active spawning and subsequent growth are closely associated with phytoplankton bloom. For overwintering stages of both species, a large deposition of lipid in the body and its gradual decrease toward the onset of phytoplankton bloom of the next year was seen. While no comparable life cycle data is presently available for M. okhotensis, the present results of M. pacifica are compared with the results from other regions, showing a large between- region variation in the life cycle patterns of this species. Further, the present results are discussed in the context of broad overwintering mechanisms of pelagic copepods living in high-latitude seas.
Colonisation and modification of soft substratum habitats by the invasive macroalga Sargassum muticum

Sargassum muticum is an invasive brown macroalga that originates from Japan. In the introduced range, thalli can grow in soft substratum habitats attached to embedded rock fragments and shells. Within Strangford Lough, Northern Ireland, S. muticum has rapidly colonised large areas of soft substrata, where dispersal by peripatetic or 'stone-walking' plants is very effective. Sediment cores were collected under and outside canopies of S. muticum in Strangford Lough (S. muticum first recorded there in 1995) and Langstone Harbour, English Channel (S. muticum first found there in 1974) to investigate modification of the infaunal assemblages. At both study sites, community analy- ses highlighted significant differences between the assemblages under the canopies and those in adjacent unvegetated areas. In Strangford Lough, the invertebrate community under the canopy con- tained a higher abundance of smaller, opportunistic, r-selected species than outside the canopy. By contrast, the communities under and outside the canopy at Langstone Harbour were similar in spe- cies composition, diversity and dominance, but overall faunal abundance was greater under the canopy. Sediment characteristics were not affected by S. muticum canopies, but the infaunal changes may be related to environmental modification; shading, flow suppression and temperature stratifica- tion were also investigated. The differences between these 2 sites indicate that localised conditions and/or the duration of colonisation of S. muticum are important in determining the nature of habitat modification.
