Particle deposition in turbulent square duct flows

Particle deposition in fully developed turbulent square duct flows is predicted using large eddy simulation for Reynolds numbers, based on the bulk flow velocity and duct width, equal to 250k, 83k and 10,320. A particle equation of motion, solved in conjunction with a Lagrangian particle tracking technique, and including Stokes drag, lift, buoyancy and gravitational forces is used to analyse the trajectory of 50, 100 and 500 μm particles. Results obtained for the fluid phase show good agreement with experimental data and the predictions of direct numerical simulations. Predictions for particles show that high-inertia particles (Stokes number, St > 12.38) tend to deposit close to the corners of the duct floor, while low-inertia particles (St < 6.43) deposit near the floor centre. Particle deposition in the vertical direction is also found to increase with flow Reynolds number, whilst in the horizontal direction deposition increases with particle size and decreases with Reynolds number. Additionally, and in both the vertical and horizontal directions, the deposition profile, as quantified by the probability density function of deposited particle locations, is more variable for small particles when compared to larger ones, independent of the flow Reynolds number.
Work-family conflict: fighting the 'good fight' (国際ワークショップ 環太平洋圏におけるワーク・ライフバランス)

The experience of work-family conflict, and attendant negative outcomes, for women who attempt to balance the often contradictory and competing identities of mother and employee is ever-present and indeed escalating. In this article, I adopt a feminist poststructural lens to focus on the discursive field of work-family interaction, which has historically been dominated by a discourse of work-family conflict, and more recently by a discourse of work-family balance or integration. I argue for a return to, and a poststructural turn upon, the discourse of ‘work-family conflict’. Rather than a focus on how to satisfy priorities of the two domains, I argue that the experience of work-family interaction is frequently experienced as negative because of an escalation of the ‘occupation’ of the family domain by the encroachment of the work sphere. Women experience conflict because they are in a battle to defend the importance of the family and their identities as mothers. A return to ‘conflict’, calling for a focus on the temporal, spatial and affective occupation of the family domain as a key dimension in the experience of work-family conflict, highlights the role of language in the construction of the subjectivity of working mother as defender. Work-family conflict is herein conceptualized as a state of war and the domain of the family is the battleground.
Study on Molecular Recognition between Euphorbia Factor L713283 and β-Tubulin via Molecular Simulation Methods

Euphorbia factor L713283 is a new lathyrane diterpene isolated from Euphorbia lathyris and shows strong anticancer activity. By using molecular similarity analysis, β-tubulin was identified as one of the possible targets of L713283. We further investigated the binding modes of L713283 with β-tubulin using molecular docking and molecular dynamics (MD) simulation methods. The results indicated that the binding site between β-tubulin and L713283 was composed of the four regions, that is, residues Phe20~Glu27, Leu225~Thr232, Phe270~Gly277, and Ile356~Met363. MM/GBSA method was used to calculate the binding free energy and determine the key residues for the association of L713283 with β-tubulin. It was found that nonpolar interactions made the major contributions for the binding. In addition, we compared the binding pocket and motion modes of L713283-free and L713283-bound β-tubulin systems. It is proposed that L713283 may bind to β-tubulin and favor the formation of αβ-tubulin dimmer. This work provides possible explanation for molecular mechanism of the anticancer agent L713283, and the strategy used here could benefit the investigation of possible target profile for those bioactive agents with unknown mechanisms.
Staphylococcus aureus in food and nares of food handlers in Kuala Pilah, Malaysia

The outbreak of food poisoning due to Staphylococcus aureus has been reported with a significant level of morbidity worldwide. In this study, 128 samples taken from nasal swabs of 64 food handlers and 64 food items were collected and analyzed for the presence of S. aureus. The antibiotic susceptibility profiles of the isolates were also determined. Cross-sectional was used as a study design in this research. The isolates were identified as S. aureus based on colonial morphology, gram stain, mannitol salt agar fermentation, catalase and coagulase test. Fifteen (23.4%) of food handlers were positive for S. aureus nasal carriage and 24 (37.5%) of food items were contaminated with an average of 8.4 x 10 6 CFU/g of S. aureus. All isolates were susceptible to oxacillin and mupirocin respectively. However, 74.4% and 5.1% isolates were resistant to penicillin and erythromycin. Our findings suggest that the prevalence of S. aureus carriage is high among our food handlers and food items. Thus, we believed that there is a need for proper training on food safety among food handlers and quality improvement in the food premises.
An Enhanced Erasure Code-Based Security Mechanism for Cloud Storage

Cloud computing offers a wide range of luxuries, such as high performance, rapid elasticity, on-demand self-service, and low cost. However, data security continues to be a significant impediment in the promotion and popularization of cloud computing. To address the problem of data leakage caused by unreliable service providers and external cyber attacks, an enhanced erasure code-based security mechanism is proposed and elaborated in terms of four aspects: data encoding, data transmission, data placement, and data reconstruction, which ensure data security throughout the whole traversing into cloud storage. Based on the mechanism, we implement a secure cloud storage system (SCSS). The key design issues, including data division, construction of generator matrix, data encoding, fragment naming, and data decoding, are also described in detail. Finally, we conduct an analysis of data availability and security and performance evaluation. Experimental results and analysis demonstrate that SCSS achieves high availability, strong security, and excellent performance.
ow to manage the urban green to improve bird diversity and community tructure

Urbanization is a fundamental environmental change, today happening at accelerated speed worldwide. Despite the strong and permanent human impact, urban biodiversity has generally proved to be surprisingly high. Quantitative information on the effect of management actions on biodiversity is often lacking but is an indispensable basis for decisions by urban planners and managers. We therefore quantified key urban variables to predict changes in avian biodiversity when their urban habitat is modified. We analysed species richness, diversity (Simpson index) and community composition of 63 bird species with reference to major urban environmental gradients at 96 sampling points in three Swiss cities. Best explanatory models were selected from candidate models following information theory, and their respective predictions were averaged based on AICc-weights. Bird species richness and diversity are negatively affected by increasing fractions of sealed area or buildings, while increasing vegetation structures, in witzerland particular trees, show positive effects. Our models predict an increase from 13 species in the absence of trees to 20 species with 46% tree cover (+54%). Coniferous trees help to maximize bird species richness, with the models predicting an increase from 14 species at sites with only deciduous woody plants to 20 species (+43%) at places with equal representation of coniferous and deciduous plants. While the analysis of the Simpson index did not show any influence of the coniferous and broadleaf woody plants mixture, sis rev evera partial redundancy analy importance to consider s
Relation of milk parameters with postpartum reproductive efficiency in cattle

The high producing dairy cow is under high metabolic demandduring the period immediately following parturition due to themetabolic demands of increased milk production. Negative energy balance probably acts similarly to under nutrition and may manifest in delayed ovarian activity by impinging on pulsatile secretion of LH. Recent studies revealed that certain milk parameters indicate the postpartum reproductive performance in exotic cattle. In the present study, milk parameters i.e. milk yield, lactose and milk urea nitrogen (MUN) were correlated with the day of first postpartum heat exhibition. Milk samples were collected from 25 lactating animals on 10 th day of calving and after weekly intervals up to 12 weeks. Milk yield was recorded and the samples were analyzed for lactose and MUN. There was a significant positive correlation between milk yield and day of first heat. Animals with high milk yield took long time to exhibit the first postpartum heat. There was no significant difference in the milk yield between the groups of animals, which conceived within 3 months and the group of animals which conceived after 3 months. Non significant negative correlation was found between milk lactose concentration and day of occurrence of first postpartum heat. There was a significant positive correlation between MUN and day of occurrence of first heat but no significant difference was found in group of animals which conceived within 3 months and the group which conceived after 3 months.
XT-map System for Locating SC Cavity Quench Position

XT-map system under development in collaboration between Kyoto University and KEK is a combined system of T-map and X-map. High resolution T-map at quench detection will give more information for improving yield in production of high performance SC Cavities. The high-density sensor distribution of the XTmap gives the high resolution. Because the huge amount of sensor lines are multiplexed at a hi-speed scanning rate in the vicinity of the sensors, the small number of signal lines makes the installation process easy and reduces the system complexity. The quench survey test with this XTmap system has been performed in the vertical test at KEK.
Application of nanosilver based preparation in ammonia reduction in broiler house

Abstract. The aim of the study was to determine the dose of a nanotechnological-mineral preparation based on nanosilver and vermiculite for an effective ammonia reduction, and the influence of the preparation on physical properties of litter and air. The preparation used was obtained by spreading water nanosilver suspension on vermiculite with an addition of 5 % of humodetrynite. Research animals were broiler chickens divided into three groups. The particular groups were differentiated regarding the prepared application. The measurements of ammonia concentrations were conducted in upper litter layer and about 30 cm above the litter. Litter temperature, humidity and pH, and air humidity and temperature were monitored. The measurements were conducted at day 5, 10, 15, 20 and 25 of the experiment. Ammonia content above the litter was reduced in group I and II. The highest ammonia concentration was observed in the control group at sampling four while the lowest one was noted in group II at sampling two. In all groups an influence of the preparation on ammonia content above the litter was visible. Decrease in ammonia concentration in experimental groups compared to the control group was more distinct than in the case of ammonia concentration above the litter. Based on the results it is difficult to determine unequivocally an influence of the preparation on litter temperature, pH and humidity, and also on air temperature and humidity. Taking into account the level of ammonia reduction, the results may be a premise for further studies in the range of nanosilver application for the sanitization of animal buildings.
Statistical analysis of the equivalent design rainfall

Statistical analyses of rainfall data are used for the design of sewerage systems and pump-stations, for the evaluation of the duration and the frequency of overflow in runoff detention facilities, for the determination of the critical influence on a municipal wastewater-treatment plant or for the protection of watercourses from storm-water runoff (e.g., from highways). The basic data in this calculation are the intensity and the duration of a rainstorm. Different procedures used in the analysis of Equivalent Design Rainfall (EDR) in Slovenia and abroad are described. The stochastic model used is presented in more detail because of its applicability for the determination of the probability of the occurrence of partial rainfalls of higher frequencies and the determination of the lower limit of rainfall evaluation. Computation procedures and the results of the evaluation of rainfall data according to the stochastic model are presented for Ljubljana.
Synergy of Virtual Visual and Auditory Displays for UAV Ground Control Stations

Unmanned aerial vehicle (UAV) operators must remotely manipulate payload sensors, while maintaining situational awareness from a displaced ground control station (GCS). Potential use of helmet-mounted displays (HMD) in piloting UAVs and controlling payload sensors has been previously investigated (de Vries & Padmos, 1997; Draper, Ruff, & LaFleur, 2001; Morphew, Shively, & Casey, 2004). Stated benefits of HMD use for targeting tasks included immersion in the search environment and possible reduction of tactical footprint. In the current study, it was hypothesized that the pairing of 3-D audio alerts with the HMD would result in more robust performance differences between HMD and CRT conditions. For this experiment, eight subjects conducted routine area searches, periodically responding to audio threat alerts. Audio alerts were given in mono, stereo, and 3-D spatialized presentation. Targeting performance differences were assessed in a baseline CRT and joystick configuration versus HMD for all audio conditions. Findings revealed more precise target acquisition performance when payload operators used the CRT/joystick configuration than the HMD. Furthermore, time on target was reduced when visual searches were aided with stereo and 3-D directional audio cues. Lastly, participants missed the fewest targets and reported lowest workload levels, when receiving 3-D audio cues. Present findings replicated reported sickness associated with HMD use. A synergistic effect of 3-D audio and HMD showed a mitigation of operator workload previously reported with the HMD. Further consideration of 3-D audio alerting for UAV operators should be investigated for benefits in target acquisition, reduced operator workload, and increased situation awareness.
The Educational and Social Profile of the Indigenous People of Ecuador: A Multidimensional Analysis

The objective of the study is to examine the educational level and the social profile of the indigenous people of Ecuador by means of a descriptive and multidimensional statistical analysis of this sector of the Ecuadorian population, based on data from the National Survey of Employment, Unemployment and Underemployment from 2015. The descriptive analysis shows the frequency and percentages of the variables used in the investigation, while the multidimensional statistical analysis is used in order to show the principal and most important criteria of differentiation and classification among the groups of people investigated. These methods involve a factorial analysis of multiple correspondences which demostrates the criteria of differentiation and a hierarchical cluster analysis to define groups of people according to their common traits.
Coastal sea responses to atmospheric forcings at two different resolutions

Abstract. We investigated coastal sea responses to three, multi-day strong wind episodes that occurred in the middle Adriatic during the Target Operational Period (TOP) of the European COastal sea OPerational observing and forecasting system (ECOOP) project. A high-resolution oceanographic model (1 km horizontal, 16 σ vertical layers) based on the modified Princeton Ocean Model (POM) was applied to a highly complex domain located in the coastal area of the eastern Adriatic Sea. The oceanographic model was nested into the Adriatic REGional model (AREG-2) covering the entire Adriatic Sea. Meteorological forcing was prepared by two atmospheric models. The coarser model was the European Centre for Medium-range Weather Forecast model (ECMWF, with horizontal and temporal resolutions of 0.25° and 6 h, respectively), and the finer one was the Aire Limitee Adaptation dynamique Developpement InterNational model (ALADIN, with horizontal and temporal resolutions of 8 km and 3 h, respectively, and winds dynamically adapted to a horizontal resolution of 2 km). The results show that small-scale atmospheric features, which arise due to the orographically complex mainland and the number of islands and were not reproduced by the coarser atmospheric model, substantially affected surface currents, mass transports, sea surface temperature (SST) and surface salinity in the coastal area during strong Bora. For strong Sirocco, the atmospheric model's resolution was important for currents on the lee sides of islands.
Exploring Nursing Students’ Experiences of Privacy in Pediatrics Ward: A Qualitative Study

Background and Objectives: Respecting privacy means respecting individuals, their dignity and independence. It is mandatory to observe privacy in health-care systems. Therefore, this study was carried out with the aim of expressing nursing students’ experience of privacy in pediatrics ward. Methods: This qualitative study was done inductively using content analysis method. The participants included 10 nursing students studying at 6th semester. The samples were selected purposefully. The semi-structured interview with each participant lasted for 30 minutes. Results: Based on data analysis obtained from students’ experiences three following major categories were obtained: The need to change pediatrics ward, lack of attention to observance of patient’s privacy and the necessity of paying attention to patient’s rights. Conclusion: The results of our study revealed that inappropriateness of ward atmosphere, ward crowdedness, training state of hospital are among factors which give rise to failure in observing privacy. Considering that maintaining privacy is one of fundamental human rights, it is also necessary to change attitudes of students and personnel and to train them in order to observe privacy. The academic staff and instructors should provide nursing and medical students with required trainings in observing privacy.
Investor sentiment and earnings management: Evidence from Korea

This paper examines whether earnings management varies with sentiment in the stock market. While many studies have focused on firm characteristics related to earnings management, this paper sheds light on the effect of aggregate investor sentiment on earnings management. The author identifies earnings management based on a firm’s tendency to meet or beat earnings thresholds (e.g., analyst forecasts, last period’s number, and zero earnings). Investor sentiment is measured by two alternative proxies: an index based on sentiment proxies suggested in recent work (Baker and Wurgler, 2007) and the level of the stock market (Conrad, Cornell and Landsman, 2002). Using a sample of firms listed on Korean Securities Market between 2003 and 2011, this study finds that a tendency of firms to meet or beat three earnings targets is negatively related to investor sentiment. This suggests that firms are more likely to engage in upward earnings management to meet analyst forecasts, to sustain recent performance, or to report positive profits during pessimistic sentiment periods than during optimistic periods. These findings may be of interest to investors and regulators, as these demonstrate that firms tend to inflate earnings to a greater extent in order to boost their stock prices during bad economic times.
Adaptation of the Balanced Scorecard : Case Study in a Fuel Distribution Company

This study aims to analyze and explain the adaptation of the balanced scorecard (BSC), through the theoretical model by Ansari, Fiss and Zajac (2010), in a fuel distribution company (nicknamed Oil Company), which is characterized in this article as a late adopter. By doing so, we place the adaptation process at the heart of our research on the diffusion of management accounting practices. The results showed that the BSC adopted in the Oil Company is compatible with other technologies observed in the organization. Regarding the cultural aspect, there was low adaptation of the practice to the organizational culture; however, no political misfits were observed. Due to this low cultural fit between the BSC and the Oil Company, in the latter the BSC has high fidelity and low extension in relation to the model observed in the extant literature. The article builds on the theoretical and empirical evidence that a specific adaptation pattern depends on the fit between the technical, cultural, and political characteristics of the practice implemented and the characteristics of the company. This is a distinctive aspect of our study, as it seeks to explain variations in the organizational practices by analyzing their consistency with the needs, objectives, and structure of the adopting company, especially considering the cultural and political aspects involved in the adaptation process.
The Utility of Diagnostic Imaging in Fish Bone Impaction

Objectives: The purpose of this pilot study was to obtain an Australian perspective on evaluating the utility of plain film radiography and computed tomography (CT) to rule out fish bone impaction in the upper aerodigestive tract in the emergency department (ED) setting. Methods: A retrospective multicentre cohort study was conducted. A total of 73 patients met the inclusion criteria. A subgroup of patients underwent CT. We studied the sensitivity and specificity of x-ray and CT along with other demographic variables to determine the likelihood of true fish bone impaction. Results: Out of the 73 patients, 28 patients had true bone impaction. The sensitivity for x-ray was 42.9% and specificity was 73.3%. The sensitivity of CT was 87.5% and specificity was 71.4%. We found a significant difference in the mean age of presentation for true bone and false bone impaction, P = 0.02. Conclusion: Due to the low sensitivity of x-ray we do not recommend the utilisation of plain film radiography to rule out bone impaction Advances in low dose radiation multidetector CT scanners may replace plain film radiography as a screening tool.
