Internal wave fields generated by a translating body in a stratified fluid: an experimental comparison

Uniform approximations for the combined permanent and transient start-up waves produced by the impulsive motion of a body in a density-stratified fluid are calculated. These new approximations to the wave field remove the unphysically diverging fluid velocities and phase shifts near the boundary of the causality envelope associated with previous non-uniform approximations. The calculated wave field is compared to experimental measurements of the wave field generated by towing a spherical body through a linearly stratified fluid. Synthetic schlieren, a technique previously used only to analyse two-dimensional or axisymmetric flow, is developed further to allow comparison with this fully three-dimensional wave field. In particular, breadth averaging across the tank is employed. Good agreement is found between the theoretical and experimental results in the far field.
Growth Parmeters in Gaks and _ t 4 k 3 A Epitaxial Films

Study on the native defects in GaAs and AlxGa1 _As grown under the various r. conditions has been made. First, model for describing the physical origins of the EL2 center in GaAs is presented based on the kinetic reaction equations and the analysis of electric-field enhanced emission rates for the four different types of potential well. It has been shown that the EL2_ center may be ascribed to two different types of native defect: One level -0.83 eV) attributing to % the antisite defect, s or the antisite cluster_ AsG-A54 is designated as the EL2a electron trap,. and the other level (tc-0.76 eV) attributing to the antisite-vacancy complex, IsGais designated as the EL2b electron trap. The " ". EL2a electron trap was found to be strongly dependent on the growth condition, e.g., [AsH'/[TMGaJ ratio, growth temperature growth rate (mainly at lower% growth rate) and buffer layer. Second, the final transition state of electron emission from the DX center to the nonspherical conduction band minima in AllGa-_iAs has been studied by capacitance-voltage measurement and Deep level X% Transient Spectroscopy experiment. The results indicate that the conduction band minimum associated with the electron emission is the L band instead of the . '-. "€' . ~ band which is the lowest conduction band. Analysis of the electric-field enhanced emission rate applied to the Coulombic and Yukawa potential well has further supported the fact that emission and capture of electron from the DX N' center is related to the L minimum in the conduction band
Status: Insights from Organizational Sociology

Status has become an increasingly influential concept in the fields of organizational and economic sociology during the past two decades. Research in this area has not only helped explain behavior within and between organizations, but has also contributed to our understanding of status processes more generally. In this review, we point to the contributions of this field in terms of the determinants of status, the effects of status, and the mechanisms by which these effects are produced. We next appraise the way in which a network approach has contributed to our formal understanding of status positions and status hierarchies. We then highlight recent studies that demonstrate the value of studying the structures of status hierarchies themselves rather than focusing solely on the actors within them. After suggesting potential directions for future research, we conclude by calling for renewed efforts to translate concepts and theories across levels of analysis and substantive commitment in order to build more general theories of status processes.
MENTAL ROTATION BETWEEN 3 1⁄2 AND 5 1⁄2 YEARS OF AGE 1 Using a Touch Screen Paradigm to Assess the Development of Mental Rotation Between 3 1⁄2 and 5 1⁄2 Years of

Mental rotation is an important spatial skill. However, there is controversy concerning its early development and susceptibility to intervention. In the present study, we assessed individual differences in the mental rotation abilities of children between 31⁄2 and 51⁄2 years of age, using a touch screen paradigm to simplify task demands. A figure or its mirror image was presented in 8 different orientations, and children indicated in which of two holes the figure would fit by touching one of the holes on the screen. Task instructions were varied in three conditions, giving the children the opportunity to gather manual or observational experience with rotations of different stimuli, or giving no additional experience. Children’s error rates and response times increased linearly with increasing angular disparity between the figure and the hole by the age of 5 years, but 4-year-olds were found to respond at chance for all angular disparities, despite the use of a touch screen paradigm. Both manual and observational experience increased the response accuracy of 5year-olds, especially for children already performing well. However, there was no effect on 4-year-olds. Results point to an emerging readiness to use mental rotation and profit from observational and manual experience at age 5.

Can Peers Improve Agricultural Productivity?

Productivity varies greatly among farmers and the source of that variation is not fully understood. Using a unique Indian household survey, we estimate peer effects on agricultural revenue. Results show that 60% of farmers' revenue is explained by peers. Input expenditures and land allocation to cash crops do not fully explain the variation in revenue, implying peers may also affect management, negotiation and marketing strategies. We verify that endogenous network formation, geography, off-farm opportunities and agricultural extension do not drive our results. Peer effects are strongest for agricultural peers and in the cultivation of a new crop.
Comparison of Clinical outcomes of Infragenicular Angioplasty between diabetic and non-diabetic patients with Peripheral Arterial Occlusive Disease

Background: Infragenicular angioplasty could salvage most of limbs under amputation impendence. We aim in our study to detect the results of infragenicular angioplasty in diabetic and non-diabetic patients with critical lower limb ischemia (CLI). Patients and methods: Between April 2014 and May 2017,infragenicular angioplasty was carried out on 139 patients out of 154 patients (as 15 patients missed the follow up program or their data were lost) with CLI (Rutherford category 4,5 or 6) whom attended to The Vascular surgery Department of Qena University and Assiut University Hospitals. After obtaining informed written consent from all subjects, they were divided into diabetic group (n=62) and non-diabetic group (n=77). For all subjects pre-procedure, ankle brachial indexes (ABI) and computed tomography angiography (CTA) had been done. The percutaneous transluminal angioplasty (PTA) procedure was done alone or combined with stenting. The investigated outcomes comprised rest ABI, primary, secondary patency rates and finally limb-salvage rates 6, 12, 24 and 36 months after treatment. Results: There were no significant differences between both groups in technical success rate (98.4 vs. 100%, P=0.133). Primary , secondary patency rates and limb salvage rates 6,12,24 and 36 months in both diabetic and non-diabetic groups were not significantly different (p value>0.001) The mean value of ankle brachial indexes was significantly increased after intervention (0.397 ± 0.125 versus 0.779 ± 0.137, t=-25.780, P<0.001) in diabetic group and (0.406 ± 0.101 versus 0.786 ± 0.121, t=-37.221, P<0.001) in non-diabetic group. Perioperative 30 day mortality was 0%. Major complications were groin hematoma in 7.3%, and formation of pseudo- aneurysms in 2.1% of subjects. Conclusion: Infragenicular percutaneous angioplasty is a valuable option in CLI management with low risk of both morbidity and mortality. The efficiency and outcomes of interventional procedures in diabetic patients is similar to that in non-diabetics.
Investigation of the Dimension Effects of Sub-30nm Multiple-Gate SOI MOSFETs by TCAD Simulation

In this paper we use the commercial semiconductor device simulator, Sentaurus, to simulate the electrical characteristics of sub-30nm multiple-gate (MG) silicon-on-insulator (SOI) MOSFETs. The gate configurations of the simulated MG SOI MOSFETs include: single-gate (SG), two kinds of double-gate (DG), triple-gate (TG), and gate-all-around (GAA). We examine the effects of the dimensions of the gate length, fin height, fin width, and the transport models for each gate configuration. The simulation results can serve as the guidelines of device design and they indicate that as the gate length scales down to 15 nm below, only GAA, TG, and DG configurations with specific fin cross-section dimensions can meet the device requirements.
Evaluation of interleukin 6 and interleukin 10 serum levels in patients with acute pancreatitis

Background: There are still no simple markers for an early prediction of the outcome in acute pancreatitis (AP). The aim of our study was to evaluate serum levels of interleukin 6 and interleukin 10 in patients with acute pancreatitis, and answer the question whether the evaluation of these parameters is able to establish a prognosis in acute pancreatitis. Material and methods: This study included 21 patients with mild acute pancreatitis (AP) and 13 patients with severe AP, with 3 deaths among them. Serum levels of IL-6 and IL-10 were determined on the day of admission (1 day) and on day 3 of the patient’s hospital stay. Results: Serum levels of IL-6 and IL-10 were higher in severe acute pancreatitis both on the 1st and the 3rd day of hospitalization. The highest levels of both interleukins were observed among patients who died because of acute pancreatitis. Conclusions: The evaluation of IL-6 and IL-10 serum levels indicates their great value in prognosticating severe acute pancreatitis and an unfavorable lethal outcome of disease.
Periphytic algae in a floodplain lake and river under low water conditions

Drought events will become more frequent due the climate change. In floodplains, periphytic algae are responsible for part of the primary production, are the principal source of organic carbon deposition, play an important role in mineralization and nutrient cycling, and are the base of the food web for many organisms. As algae distribution in aquatic environments is a strong indicator of physical and chemical conditions of the sites, we aimed to determine the structure of periphytic algae in lentic and lotic environments during drought conditions and to uncover the main local abiotic factors in community structuring. We hypothesized diatoms would be more frequent than green algae and desmids at both sites, due to their resistance characteristics, and that higher periphyton algal richness, density and diversity would occur in the lake due to the greater availability of nutrients and the absence of flow. The study was carried out in the Finado Raimundo lake and the Ivinhema river in the Upper Parana river floodplain during the low water period of 2011. Petioles of the aquatic macrophyte Eichhornia azurea (Sw.) Kunth were used as a substrate for periphytic algae. We found a total of 171 species, 104 species in the lake and 80 in the river. Diatoms were predominant at both sites due to their strategic traits, and between sites, there were different patterns in the periphytic algal community structure, owing to the distinctive physical and chemical characteristics of the lake and the river. Achnanthidium minutissimum (Kutzing) Czarnecki and Nitzschia palea (Kutzing) W. Smith were the most abundant species in both environments. Our results showed patterns of periphytic algae in a floodplain during drought conditions, which will assist in understanding their structuring during future drought scenarios.
Detection of multidrug resistance Aeromonas hydrophila in farm raised fresh water prawns.

This study was undertaken for isolation, identification and determination of antibiogram profile of Aeromonas hydrophila in farm raised fresh water prawn (Macrobrachium rosenbergii) on five commercial ghers. Fresh water prawns (n=25) were collected from five ghers located at Satkhira, Bagerhat and Khulna districts of Bangladesh. Brain (n=25), muscle (n=25) and intestine (n=25) samples were collected aseptically from fresh water prawn and inoculated into alkaline peptone (APW) water for enrichment at 37℃ for 8 h. Enriched cultured was streaked into Thiosulfate Citrate Bile Salt Sucrose (TCBS) agar to isolate bacteria. Bacteria were identified by cultural, Gram staining, biochemical properties and polymerase chain reaction (PCR) assay. The antibiogram profiles of bacteria were investigated against 5 commonly used antibiotics (Gentamicin, Cefalexin, Ampicillin, Azithromycin and Ciprofloxacin) by disc diffusion method. Thirteen A. hydrophila isolates were identified and the prevalence of the A. hydrophila in fresh water prawn was 17.33%. All 13 (100%) isolates were sensitive to Ciprofloxacin, Gentamicin, Azithromycin and resistant to Ampicillin and Cefalexin. The results of this study indicate that farm raised fresh water prawn harbor multidrug resistant A. hydrophila which might causes public health problem if enter into human food chain.
The Evasion Gamble Behavioural Insights on Tax Compliance

The thesis explores the insights from behavioural economic research for tax compliance. The theoretical model of tax evasion by Allingham and Sandmo (1972) is reviewed and then enriched with findings from research on bounded rationality and unbounded motivation for human behaviour. In specific implications for tax compliance of loss aversion, overweighting of low probabilities, small sample bias and procrastination are discussed. It is suggested that the perception of probabilities and the tendency to procrastinate affect the decision on whether or not to comply taxes. Further, implications for tax compliance of moral motivation, conditional cooperation and the threat of intrinsic motivation being crowded out are discussed. The act of complying, even when the risk of getting caught is low, indicate that people do not behave entirely selfinterested. To explore the evasion decision further, and look in depth at some of the phenomena discussed, a survey-experiment is conducted. The objective is to study whether peoples’ tendency to overweigh low probabilities and their propensity to confirm to social norms affect their willingness to consider hiring black labour. The results from the experiment are reported at the end of the thesis. The main finding is that people overweigh low probabilities and that it affects their decision on considering hiring black labour.
Fishing site choice modelling using Vessel Monitoring System data

In this paper, EU Vessel Monitoring System (VMS) data is combined with other site and vessel information and used to model the fishing site choice decision of Irish demersal otter trawlers. Uniquely, the fishing ground options used in the analysis reflect the actual seabed contours trawled by the fleet. The fishing site choice model, based on this natural site definition is compared to an alternative destination choice model where the fleet decision is specified using a grid based site definition as employed in previous work. It is argued that the natural site specification is a more realistic specification of the fisher site choice decision. Using the preferred natural fishing site choice model, a policy option involving the hypothetical closure of one of the fishing ground options is then simulated to examine the possible redistribution of fishing effort.
Civic and Political Involvement among Young Adults: Exploring Political Talk, Political Efficacy and Political Participation in a Community Context

This study expands research on uses and gratifications by exploring political information-seeking uses of the Internet and social networking sites (SNS) and their relationships with political efficacy and political participation. Approximately 300 young adults completed a survey covering information-seeking, information access, and information sharing uses for local civic and political purposes. The study hypothesizes that young adults’ political talk, particularly in their online social networks, is associated with political efficacy. Variables that support the relationship between information-seeking and political efficacy are also explored. Random and convenience samples of young adults were combined in this study to explore the cognitive (perceived efficacy) and civic (actual behavior) behaviors of undergraduate students at Virginia Tech in order to examine the role of political talk in individuals’ opinion networks measured by the outcome of political talk. Results show considerable support for hypotheses emphasizing the predicted relationships between Internet and SNS for political information-seeking uses, political efficacy, and political participation gratifications. Future research exploring the broad range of political communication uses and their association with political efficacy and political participation is warranted.
The effects of school entry laws on educational attainment and starting wages in an early tracking system

Empirical evidence indicates that relative age, which is determined by date of birth and the school entry cutoff date, has a causal effect on track choice. Using a sample of male labor market entrants drawn from Austrian register data, I analyze whether the initial assignment to different school tracks has persistent effects on educational attainment and earnings in the first years of the career. I estimate the reduced-form effect of the school entry law on starting wages and find a wage penalty of 1.1-2.0 percent for students born in August (the youngest) compared to students born in September (the oldest). The analysis of educational attainment shows that significant differences exist in the type of education. Younger students are more likely to pursue an apprenticeship and less likely to have higher education. After five years of labor market experience, the wage penalty amounts to 0.8-1.1 percent, suggesting a persistent (albeit decreasing) negative effect of the school entry rule on earnings.
1 Efficiency of true-green light emitting diodes : 2 non-uniformity and temperature effects 3

External quantum efficiency of industrial-grade green InGaN light-emitting diodes (LEDs) 16 has been measured in a wide range of operating currents at various temperatures from 13 K to 300 17 K. Unlike blue LEDs, the efficiency as a function of current is found to have a multi-peak character, 18 which could not be fitted by a simple ABC-model. This observation correlated with splitting of LED 19 emission spectra into two peaks at certain currents. The characterization data are interpreted in terms 20 of non-uniformity of the LED active region, which is tentatively attributed to extended defects like 21 V-pits. We suggest a new approach to evaluation of temperature-dependent light extraction and in22 ternal quantum efficiencies taking into account the active region non-uniformity. As a result, the 23 temperature dependence of light extraction and internal quantum efficiencies have been evaluated 24 in the temperature range mentioned above and compared with those of blue LEDs. 25
SERIOUS GAMES FOR LEARNING – A REVIEW OF THE LITERATURE

The rise of digital games over recent years has been exponential. While many are used for entertainment, digital games have also begun to permeate education — which has lead to the coining of the term ―serious games‖ [1]. Proponents of serious games argue that they hold enormous potential for learning [2], by embodying a range of pedagogical strategies. While some have adopted commercial games for use in the classroom, others have designed games specifically for educational purposes. However, designing complex and realistic serious games with limited budgets and resources is difficult. In addition, achieving a successful balance between the competing goals of teaching and entertaining is extremely challenging. This paper describes a project undertaken at the Dublin Institute of Technology, which involved designing a serious game to teach food safety principles to undergraduates. The design strategy and process will be outlined, paying particular attention to the theoretical underpinnings of pedagogical design and game design. Results of initial pilots will be outlined. The paper concludes by reflecting on lessons learned during the course of this project and by suggesting implications for the development and implementation of serious games in the wider Higher Education sector. Plans for future research in the area will also be detailed.

Methodology/ApproachThe researchers develop a conceptual framework, from a literature review and qualitative interviews, which outlines the benefits of manufacturers’ brands for retailers. A series of hypotheses tests the effects of these brand benefits on retailer brand attitudes. Data is collected using a survey of supermarket category buyers and analysed with structural equation modelling in order to validate this framework.
PROVINCIAL INTERNATIONAL MIGRATION IN SPAIN: WHICH FACTORS ARE BEHIND?

International migration has become one of the most heated topics of research in the last two decades. This paper investigates the main determinants behind the settlement pattern of international migration across the Spanish provinces over the period 2000-2009. To accomplish this aim, after dealing with spatial dependence on data through a proper filtering technique, the paper estimates a migration equation. The results reveal that social networks and some economic factors such as unemployment and per capita income play a key role in explaining international migration in Spain.
Increase Predictability in Complex Engineering and Fabrication Projects

This paper addresses alternative measures to add to the Last Planner System to increase predictability in the delivery of complex engineering and fabrication projects. Linear models have proven insufficient for planning and production control of design processes due to the iterative nature of design and engineering activities. In addition, practitioners have questioned the function of the Last Planner System in design. Thus, the purpose of the paper is to report research on the right combination of tools to increase predictability. The constructive research approach was used to analyze a case from the subsea oil and gas industry with low on-time delivery of documents and drawings. The construct divides the execution phase into a design phase and documentation and drawing phase. The design phase utilizes ideas from Scrum and the Last Planner System. Completion of documents and drawings are postponed until completion of a 3D model of the product, thus reducing the amount of negative iterations currently experienced. The documentation and drawing phase utilizes ideas from Critical Chain and the Last Planner System. It has been verified that the division of the execution phase is a significant improvement within the case enterprise, and we seek to generalize the findings.
