Single-particle dispersion in stably stratified turbulence

We present models for single-particle dispersion in vertical and horizontal directions of stably stratified flows. The model in the vertical direction is based on the observed Lagrangian spectrum of the vertical velocity, while the model in the horizontal direction is a combination of a continuous-time eddy-constrained random walk process with a contribution to transport from horizontal winds. Transport at times larger than the Lagrangian turnover time is not universal and dependent on these winds. The models yield results in good agreement with direct numerical simulations of stratified turbulence, for which single-particle dispersion differs from the well studied case of homogeneous and isotropic turbulence.

Determination of effective dose of garlic for controlling seed-borne fungal disease of tomato.

Tomato seeds collected from farmer’s were treated with garlic tablet at concentration 1:3 w/v, 1:4 w/v, 1:5 w/v and 1:6 w/v for controlling seedborne fungal diseases. Seed health status of treated seeds was evaluated following blotter incubation method. Three different fungal pathogens viz., Aspergillus spp. , Fusarium spp. and Penicillium spp. were identified from seed samples by blotter incubation method. Garlic tablet at 1:3 w/v dose showed better performance in increasing seed germination and reducing prevalance of fungal pathogens over control treatment. The highest germination recorded was 71.25% at 1:3 w/v dose of garlic tablet which represents an increase of 11.25% over control. Germination percentage was increased 18.75% over control when treated seeds were sown in tray soil. Substantial importance in seed quality was noticed in reducing hard seed, damping off, blighted seedlings and tip over. In pot experiment, 1:3 w/v dose also performed best to yield the lowest percentage of hard seed, damping off, blighted seedlings, tip over and seedlings with highest seed germination.
MOKSLAS – LIETUVOS ATEITIS SCIENCE – FUTURE OF LITHUANIA

The article discusses the process of changing the shape of urban waterfronts by the Lusatian Neisse River in Gubin and Guben, comparing the post-war urban solutions with the pre-war ones. Among others, the elements of urban composition, first introduced by K. Wejchert and K. Lynch, have been applied in the analysis. What has been discovered is that visual openings, compositional dominants, possible connections and other urban bonds were ruined, which resulted in spatial fragmentation. The urban factors are presented taking into account the holistic background of the complex social and political situation of the divided city.
Safeguarding Malaysia’s Cyberspace against Cyber Threats: Contributions by CyberSecurity Malaysia

The world today is becoming dependent on Information and Communication Technology (ICT). Cyber threats on ICT infrastructures can lead to catastrophic damage and disruption, hence an effective information security policy framework is vital in securing the Critical National Information Infrastructure (CNII). Malaysia has implemented the National Cyber Security Policy (NCSP) to safeguard Malaysia’s CNII against cyber threats. The implementation of NCSP initiatives requires the commitment and involvement of multiple stakeholders to ensure continuous momentum. Thanks to the implementation of the NCSP initiatives, Malaysia’s commitment and effort in ensuring resilience against cyber threats has been recognized at the international level.
Size-dependent creep behaviour of plasma-enhanced chemical vapour deposited silicon oxide films

The time-dependent plastic deformation (creep) behaviours of both as-deposited and annealed plasma-enhanced chemical vapour deposited (PECVD) silicon oxide (SiOx) films were probed by nanoindentation load relaxation tests at room temperature. Our experiments found a strong size effect in the creep responses of the as-deposited PECVD SiOx thin films, which was much reduced after rapid thermal annealing. Based on the experimental results, the deformation mechanism is depicted by the ‘shear transformation zone’ (STZ)-based amorphous plasticity theories. The physical origin of the STZ is elucidated and linked with the shear banding dynamics. It is postulated that the high strain gradient at shallow indentation depths may be responsible for the reduction in the stress exponent n = ∂ log(strain rate)/∂ log(stress), characteristic of a more homogeneous flow behaviour.
Design of UHF RFID Reader Antennas Using Coupled Line Power Divider and Narrow Bandpass Filter

In this paper, a Circularly Polarised (CP) universal Ultra-High-Frequency (UHF) RFID reader antenna based on coupled line power divider is firstly proposed. The antenna features compact size, simple structure and low-cost and achieves Return Loss (RL)≥25.5 dB, gain≥5.5 dBic and Axial Ratio (AR)≤1.8 dB, over the universal UHF RFID band of 840 to 955 MHz and the 3-dB AR beam-width is more than 110°. Then, an improved bandpass filter based on coupled lines and a ring resonator is proposed for achieving extremely narrow frequency response. A CP filter reader antenna using this narrow bandpass filter is proposed for enhancing the reliability of the communication and reducing the cost of the microwave front end in RFID system. The filter antenna exhibits the measured 1-dB gain (gain>6.4 dBic) bandwidth from 905 to 930 MHz and RL≥15 dB, AR≤1.4 dB in the band.
The Structured Employment Interview: An Examination of Construct and Criterion Validity

This study extends the literature on interview validity by attempting to create a structured employment interview with both constructand criterion-related validity. For this study, a situational interview was developed with the specific purpose of enhancing the interview’s construct validity while retaining the interview’s predictive power. To enhance the construct validity, two guidelines were applied to the creation of the interview based on previous research in interview and assessment center literature—(1) limit the number of applicant characteristics to be rated to 3; and (2) ensure that the dimensions to be measured are conceptually distinct. Based on these two guidelines, three constructs were chosen for assessment of real estate sales agents—extraversion, proactive personality and customer orientation. The critical incident technique was used to develop six interview items. To test the construct validity of the interview, the six items were correlated with other measures, specifically, self-report questionnaires and managers’ ratings, of extraversion, proactivity and customer orientation. Correlations were weak, at best (rs ranged from -.06 to .25). To test the predictive validity of the interview, the six items were correlated with both objective and subjective measures of performance. Predictive validities were stronger, ranging from . 23 to . 30. These findings are consistent with previous research on employment interviews which have found that although the predictive validity of the interview is strong, the construct validity is very weak, leaving researchers to wonder what it is that the interview is actually measuring. Possible explanations for these findings are offered, and the implications of these findings are discussed.

The Effect of Turbulent Uniform Flow around A Square Cylinder

Turbulent uniform flows past a two-dimensional square cylinder are investigated numerically. By varying the turbulence intensity and turbulence length scale of the approaching flow, the flow behaviour and the flow effect of the cylinder are compared to that in a laminar approaching-flow case. In addition, the variations of drag and lift with respect to the changes of turbulence intensity and turbulence length scale are analyzed on a systematic basis. In the study, the method of large eddy simulation is adopted. The approaching-flow turbulence is considered homogeneous and isotropic and is generated by a spectral method according to Karman spectrum. Two levels of turbulence intensities (5% and 10%) and three turbulence length scales (0.25, 0.50 and 1.0 times of the cylinder width) are selected in the program to examine the effect on the cylinder due to existing turbulence in the approaching-flow. Results show that the Strouhal number associated with the turbulent approaching flows remains unchanged compared to that in the laminar approaching-flow case. On the other hand, approaching-flow turbulence has noticeable effect on the resulting drag and lift. When the approaching flow becomes turbulent, generally, the resulting mean and root-mean-square values of drag as well as the magnitude of lift fluctuations are promoted. An increase of the turbulence length scale leads to a mild increase of the mean drag and the fluctuating lift, while the effect due to a change of the turbulence intensity appears insignificant. Moreover, a larger value of turbulence intensity results in a greater value of drag fluctuation.

Evaluation of Health Related Quality of Life in Patients Candidate for Spine Surgery

Purpose: The aim of the present study was to assess the quality of life of patients who are candidates for spine surgery using a quality of life measure adjusted according to age and sex. Methods: The SF-36 health questionnaire was administered consecutively to patients admitted for spine surgery. They were classified according to their clinical status: low back pain, lumbar radiculopathy, neurogenic claudication, cervical radiculopathy and cervical myelopathy. Associated morbidities were registered retrospectively using the Charlson comorbidity index. Bivariate and multivariate analyses were performed to compare the groups with each other, with the general average population and with the average population adjusted by age and sex using standardized T values. Results: 284 patients with an average age of 49.6 years (SD=12.9) were assessed. Patients awaiting lumbar spine surgery are those who showed the worst results on both the physical and mental scales. Patients with radicular pain only showed worse results than patients with low back pain on the bodily pain scale. These results were not influenced by the associated co-morbidities. Conclusions: The use of the SF-36 scores through standardized and age- and sex-adjusted T values provides a better appreciation of the differences between various diseases. Patients awaiting lumbar spine surgery are associated with a poorer quality of life than patients awaiting cervical spine surgery. Radicular pain in patients with lumbar pathology is only associated with a worsening on the bodily pain scale.

Enhanced Photocatalytic Activity of Ce 3 +-TiO 2 Hydrosols in Aqueous and 1 Gaseous Phases 2 3

Gaseous Phases 2 3 Tong-xu Liu, Xiang-zhong Li*, Fang-bai Li 4 a Department of Civil and Structural Engineering, The Hong Kong Polytechnic University, Kowloon, Hong Kong, China 5 b Guangdong Key Laboratory of Agricultural Environment Pollution Integrated Control, Guangdong Institute of Eco-Environment 6 and Soil Science, Guangzhou 510650, PR China 7 8 Abstract 9 A series of cerium ion-doped titanium dioxide (Ce-TiO2) hydrosols were prepared by a 10 coprecipitation–peptization method and characterized by UV–Vis transmittance spectroscopy (T%), 11 particle size distribution (PSD), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET) and 12 Barret-Joyner-Halender methods (BJH), respectively. The results demonstrated that as the doped 13 Ce content increased, the crystalline size, BET surface area and transmittance decreased 14 significantly, but the particle size increased gradually. The photocatalytic activity of Ce-TiO2 15 hydrosols was evaluated in aqueous solution for methylene blue (MB) and 2,3-dichloriphenol (2,316 DCP) degradations, and also in gaseous phase for benzene degradation. The results showed that the 17 overall photocatalytic activity of Ce-TiO2 hydrosols in aqueous and gaseous phases under UVA 18 and visible illumination was significantly higher than pure TiO2 hydrosol due to its better separation 19 of electron-hole pairs and visible light response. Additionally, the formation surface-complex of 20 TiO2 and 2,3-DCP with visible-light-response is also contributed to the 2,3-DCP degradation, and 21 the relevant possible reaction mechanisms were discussed with details. The kinetic data 22 demonstrated that the Ce-TiO2 hydrosols with the content of Ce doping between 0.5-1% 23 achieved the best performance in both the aqueous and gaseous phases. This study provided the 24 comprehensive understanding of the Ce-TiO2 hydrosol characteristics and reaction mechanisms, 25 and the results indicate that these Ce-TiO2 hydrosols may have good potential for pollutant 26 degradation either in aqueous phase or gaseous phase. 27 28
Option pricing for a partially observed pure jump price process

Financial asset price movements are considered, where the risky asset price is a marked point process. Let its dynamics depend on an underlying event arrivals process which is assumed to be a marked point process unobserved by the market agents. Taking into account the presence of catastrophic events, the possibility of common jump times between the risky asset price process and the arrivals process is allowed. The equivalent martingale measures are characterized. The arbitrage-free pricing of a European contingent claim is identied as the conditional ex- pectation with respect to the observations under the minimal martingale measure.
NUTRACEUTICAL IN MALE REPRODUCTION

In order to obtain a successful outcome in artificial insemination programs, a few precautions must be taken with regard to male breeders. It is established that environmental factors can change the hormonal secretion, the cell differentiation that occurs in the testicles, as well as sperm maturation and transport in the epididymis. In view of adverse nutritional factors, reproductive organs can present degeneration and disorders in different degrees and intensities, affecting the animal fertility. The term nutraceutical describes products derived from foods, which may provide additional health benefits, beyond the basic value found in diets. Among the main nutraceuticals used in male reproduction, there are omega-3, arginine, B-complex vitamins, L-carnitine, β-carotene and antioxidants. The aim of this paper is to present the main substances used as nutraceuticals, in order to improve semen quality, obtaining most favorable outcomes in the use of artificial insemination.
In situ study of the physical mechanisms controlling induced seismicity at Monticello Reservoir, South Carolina

In two ∼1.1-km-deep wells, the magnitudes of the principal in situ stresses, pore pressure, permeability, and the distribution of faults, fractures, and joints were measured directly in the hypocentral zones of earthquakes induced by impoundment of Monticello Reservoir, South Carolina. Analysis of these data suggests that the earthquakes were caused by an increase in subsurface pore pressure sufficiently large to trigger reverse-type fault motion on preexisting fault planes in a zone of relatively large shear stresses near the surface. The measurements indicated (1) near-critical stress differences for reverse-type fault motion at depths less than 200–300 m, (2) possibly increased pore pressure at depth relative to preimpoundment conditions, (3) the existence of fault planes in situ with orientations similar to those determined from composite focal plane mechanisms, and (4) in situ hydraulic diffusivities that agree well with the size of the seismically active area and time over which fluid flow would be expected to migrate into the zone of seismicity. Our physical model of the seismicity suggests that infrequent future earthquakes will occur at Monticello Reservoir as a result of eventual pore fluid diffusion into isolated zones of low permeability. Future seismic activity at Monticello Reservoir is expected to be limited in magnitude by the small dimensions of the seismogenic zones.
Patterns of structural changes in construction

The changing role of construction at various stages of development has been at the core of debate in the field of construction economics. It has been argued that the construction industry should follow the pattern of manufacturing, its primary supplier, rather than services, even if early studies suggested an S-shaped relationship with GDP per capita. The presented analysis stems from this well known literature and again it focuses on the link between construction share in value added and development measures. The conventional view that GDP per capita suffices is critically discussed and new variables that help the explanation of such a relationship are introduced. Discussion builds upon the comparison of standard cross country regressions in the 1970 and in 2005. Even if explicative power is quite weak it is shown that in recent years construction has been linked with new variables such as market size and population density.

Meta-analysis of Advertising Elasticity Estimates: How to Correct for the Sampling Error Bias

Meta-analysis is a powerful statistical technique that allows social scientists to cumulate research findings across studies. Marketing researchers have used meta-analysis to measure the effectiveness of marketing mix strategies⁄ e.g., advertising, pricing, and promotion. Typically, researchers determine an average elasticity as a measure of the strategy to influence sales, and try to demonstrate causal relationship between the elasticity and some moderator variables. However, extreme caution should be exercised before making any causal inference from meta-analytic results. For example, the variance of an elasticity may be biased due to the sampling error in each estimate. Hence, the sampling error variance must be measured and accounted for before attempting to unravel any causal relationship between the elasticity and moderator variables. In this study by Bandyopadhyay⁄ a meta-analysis of advertising elasticity is done to demonstrate how to correct for the sampling error variance and measure the effect of moderator variables on elasticities. The results, according to the author, can help brand managers make useful inferences about the overall advertising effectiveness.
