Is Vegetarianism Related to Anxio-Depressive Symptomatology? A Cross-Sectional Survey in A Large French Sample

Objective. Many studies indicate a link between vegetarianism and mental health, but the relationship remains uncertain. The aim of the present study is to examine the cross-sectional association between anxio-depressive symptomatology, happiness, and vegetarianism in a French sample while controlling for relevant confounders. Design. Self-reported questionnaire data were obtained from a large cross-sectional sample.Participants and setting. 9993 participants aged 18-99, 70.8% females participated in an online survey. Results. A logistic regression analysis was performed to estimate the Odds Ratio (OR) and 95% Confidence Interval (95% CI) of anxiety, depression, happiness, and self-reported health to predict vegetarian diet, controlling for age, gender, BMI, educational level, monthly income, and city size. Vegetarians did not present an increased risk of anxiety or depression. However, they reported lower happiness than did non-vegetarians, and exhibited better self-reported health than did omnivores. Conclusion. Vegetarian diet was not found to be related to anxiety or depressive symptoms. However, vegetarians presented lower levels of happiness. This result may be interpreted as a consequence of the social status of vegetarianism in France.
A systematic review of parental vaccine hesitancy and refusal in childhood vaccination

Background Acceptance of vaccines is an important predictor of vaccine uptake. This has public health implications as those who are not vaccinated are at a higher risk of infection from vaccine preventable diseases. We aimed to systematically review studies of parental attitudes and beliefs in childhood vaccination, with a focus on the methods used to measure hesitancy and refusal.Methods We identified and reviewed primary research studies using quantitative methods and investigating vaccine attitudes and beliefs published between January 2012 and May 2018. Studies were included if they involved a quantitative survey of the attitudes and beliefs of parents about vaccinations recommended for children. We undertook a narrative synthesis of the results with a focus on evaluating variation in the use of behavioural theories, validated survey instruments, and localisation and adaptation of questions to suit local context.Results A total of 116 studies met the inclusion criteria; 99 used a cross sectional study design, 5 used a case control study design, 4 used a pre-post study design and 8 used mixed methods study designs. Sample sizes of included studies ranged from 49 to 12,259. Thirty-six countries were represented in the included studies. The most commonly used tool was the Parent Attitudes about Childhood Vaccines (PACV) Survey. Questions eliciting vaccination attitudes and beliefs varied widely.Conclusions There was heterogeneity in the types of measures used in studies investigating attitudes and beliefs about vaccination in parents. Broader and more consistent use of validated survey instruments for measuring parental attitudes and beliefs about childhood vaccination would help to better understand localised differences in the reasons for vaccine hesitancy and refusal.
Incorporating Network Coding into TCP Grounded on Network Utility Maximization in Multi-Radio Multi-Channel Wireless Mesh Networks

A new approach, named TCP-I 2 NC, is proposed to improve the interaction between network coding and TCP and maximize the network utility in interference-free multi-radio multi-channel wireless mesh networks. It is grounded on a NUM formulation, and this NUM problem is decomposed into a rate control problem and a packet scheduling problem. The solutions to these two problems perform resource allocation among different flows. Simulations demonstrate that TCP-I 2 NC derives a significant throughput gain and a small delay jitter Network resource is fairly allocated via the solution to the NUM problem and the whole system also runs stably. Moreover, TCP-I 2 NC is compatible with traditional TCP variants.
Refinery operations and control: A future vision

In this paper the author takes an educated guess on how refineries will be operated ten to fifteen years out. He has tried to strike a balance between the Gee Whiz what marvels could be worked, and some practical realities of a conservative industry with many legacy systems and evolutionary approach to change. He first takes a look at four basic trends and practical realities that will influence how one operates and controls the business in the future: financial and capital situation; basic refining process knowledge; instrumentation and measurement; and computing technology. These factors will significantly influence how far the industry can go in total automation, and where it will still need people involvement on a routine basis.

European Journal of Physical Education and Sport Science-2501-1235

The aim of this article was to monitor and improve the number of steps on speed through a 12-week training program for young players in the city of Elbasan. The 12 week training intervention was carried out with the focus on biomechanical running parameters and mainly on the densities of the steps during the training sessions. The participants in this study were 28 younger players 15.1 ± 0.3 years (control group and intrusion group). The speed time (50m sprint) was evaluated during the sprint test (50m) and also the anthropometric parameters (weight, height, body fat in percentage) were measured at both study times (first T1 measurements and T2 second measurements). Skin thickness measurements were used to estimate the percentage of the body fat of the child. Data from the analysis on this research study by groups show that there is an improvement in mean values for step counts from T1 to T2 as follows; for control group by 1.3 steps (SD 0.8 seconds; t= 4 p=0.01) while for intervention group there is an improvement also by 2.8 steps (SD 1.1 steps; t= 5.7 p=0.005). Finally, statistical analysis show a significant difference in improvements (T1 to T2) between groups for the number of steps (p= 0.03) in favor of the improvement of the intervention group.
System Architecture Definition of the DelFFi Command and Data Handling Subsystem

DelFFi is a CubeSat mission with the objective to demonstrate formation flying and explore the composition of the upper atmosphere. The research performed in this master thesis focusses on the development of the system architecture of the Command and Data Handling Subsystem of the two identical satellites. Specifically three questions are answered: What is the current status and what work is remaining? How can system modes and states be defined for the system architecture of a CubeSat? Finally, what are the possibilities to include error detection and handling on a nanosatellite. The Command and Data Handling Subsystem consists of two general components: Hardware and Software. Analysis shows that the hardware components are close to a mature \ac{TRL} between four and nine. Conversely, the development of the on-board software is at an early stage of development with a \ac{TRL} for most items equal to, or below, three. As a consequence of the second research question, this work attempts to determine what the system is performing at certain moments in time by defining system phases, modes and states. On the basis of academic and industry literature, a 6-step system engineering methodology has been developed in this thesis for the application to CubeSat missions. Beginning from the mission objectives, the operational stakeholders and their uses cases, a top-down flow allows the definition of the system modes and corresponding states. Implemented for DelFFi, a total 10 modes and 33 states have been defined. One special mode is the safe mode, which assures the survival of the satellite in non-nominal conditions. The spacecraft transition into this mode by ground command or autonomously due to Failure, Detection, Isolation and Recovery procedures(FDIR). On the basis of analysis into the different CDHS configuration items FDIR procedures have been implemented successfully into the DelFFi software architecture. To summarize the research performed within this thesis successfully furthered the system architecture of the DelFFi CDHS by defining the System Modes and Phases and implementing FDIR procedures.
A NEW SOFT-ENGINEERING ALTERNATIVE TO TRADITIONAL DREDGING STRATEGIES

Sediment transport and sedimentation problems at tidal inlets and navigational channels are still worldwide issues to be addressed. Furthermore, future challenges such as climate change and the adaptation of coastal areas increase the uncertainties of the future evolution of these systems. However, dredging strategies are carried out following traditional layouts, such as channel deepening, lasting short periods of time despite the high economic expenditures and the potential environmental impacts derived from the increase on water turbidity and dispersion of contaminants. This work proposes a new soft-engineering dredging strategy for tidal inlets, analyzing its morphodynamic evolution by means of numerical modeling. The model, used to obtain the hydro-morphodynamic evolution of the inlet, is applied to Punta Umbría inlet (Southern Spain). The simulations were successfully calibrated and tested both for hydrodynamics and morphodynamics and later applied to different dredging strategies, including traditional alternatives, such as channel deepening and littoral drift barrier, and a new soft-engineering solution based on shoal removal. Among these strategies, the shoal removal, which is designed to minimize the energy gradients at the navigational channel, is found to be the most efficient on the basis of the operativity of the channel for different vessel draughts; being this operativity improved up to 60% compared to the traditional strategies. This solution, which reduces the frequency of the maintenance of the channel depths, may be suitable for other inlets with compromised navigational capacities due to the presence of ebb shoals. Furthermore, it reduces the frequency of high turbidity and contaminant concentration episodes, which is of major interest in areas, such as Punta Umbría inlet, where the pollution derived from the soil content of heavy metals is important. After the analysis of the correlations between the main maritime drivers and the morphodynamic changes, we conclude that the morphodynamic evolution of the navigational channels is closely related not only to the energetic content of ocean waves, but also (and significantly) to the wave directionality.
National followers in the students use of educational technologies instruction of interests

This article discusses how to use the craft of national crafts. More importantly, the role of the teacher in the learning process is determined by the fact that the learners are helped by independent learning. In addition to teaching the readers not only the knowledge they have, they also understand their role in teaching independent, creative thinking, critical thinking about their personality and knowledge, analyzing information, identifying what needs to be done, drawing conclusions, and teaching their own ideas. The main purpose of collaborative learning is to work on a common problem and focus on the problem.
Evaluating Malaysia's e-government flagship applications using the DeLone and McLean

This study had used the DeLone and McLean (2003, 2004) up-stream model of e-commerce success to evaluate Malaysia’s e-government flagship applications In this article, we present the evaluation results of Malaysia’s six e-government flagship applications from internal end-users’ perspective. The six flagship applications assessed were eservices, e-procurement, generic office environment, human resource management information system, project monitoring system and electronic labor exchange.This study adopted a cross-sectional survey research approach. A total of 437 questionnaires were distributed to non-clerical staff at seven lead implementing agencies namely the Road Transport Department (RTD), Treasury, the Malaysia Administration and Modernisation Planning Unit (MAMPU), Public Service Department (PSD), Ministry of Human Resources (MOHR), the Implementation Coordination Unit (ICU) and the Ministry of Health (MOH). The usable response rate was 29.7%. There was evidence to suggest that the e-government applications were generally successful in lead implementing agencies.
POSDCORB: core patterns of administration

This manuscript extends Luther Gulick's organizational patterns. Patterns are a way to integrate complex theories and practices. Yet administrative, legal and constitutional contexts may not always be clear. Gulick gave voice to POSDCORB within a notable pattern-based discussion. The respective elements, consistent with the designs of Christopher Alexander, are suggested as being true invariants. A careful reading of Gulick's work reveals techniques of design when he planned the reorganization of New York City and the Executive Office of the President. From his lineage, it is suggested that Gulick practiced a newly coined technique called multiple social inheritance. The application of other techniques, such as organizational polymorphism and socio-encapsulation, are also discussed. The Hillside Group's patterns community is dedicated to developing patterns. Their refined structure was used to document the POSDCORB-based patterns, both in parts and as a whole. While the POSDCORB elements are certainly not the only administrative patterns, they may be representative of the core.
Fast and Robust Design of CMOS VCO for Optimal Performance

The exponentially growing design complexity with technological advancement calls for a large scope in the analog and mixed signal integrated circuit design automation. In the automation process, performance optimization under different environmental constraints is of prime importance. The analog integrated circuits design strongly requires addressing multiple competing performance objectives for optimization with ability to find global solutions in a constrained environment. The integrated circuit (IC) performances are significantly affected by the device, interconnect and package parasitics. Inclusion of circuit parasitics in the design phase along with performance optimization has become a bare necessity for faster prototyping. Besides this, the fabrication process variations have a predominant effect on the circuit performance, which is directly linked to the acceptability of manufactured integrated circuit chips. This necessitates a manufacturing process tolerant design. The development of analog IC design methods exploiting the computational intelligence of evolutionary techniques for optimization, integrating the circuit parasitic in the design optimization process in a more meaningful way and developing process fluctuation tolerant optimal design is the central theme of this thesis. Evolutionary computing multi-objective optimization techniques such as Non-dominated Sorting Genetic Algorithm-II and Infeasibility Driven Evolutionary Algorithm are used in this thesis for the development of parasitic aware design techniques for analog ICs. The realistic physical and process constraints are integrated in the proposed design technique. A fast design methodology based on one of the efficient optimization technique is developed and an extensive worst case process variation analysis is performed. This work also presents a novel process corner variation aware analog IC design methodology, which would effectively increase the yield of chips in the acceptable performance window. The performance of all the presented techniques is demonstrated through the application to CMOS ring oscillators, current starved and xi differential voltage controlled oscillators, designed in Cadence Virtuoso Analog Design Environment.
Survey Quality

Survey quality is a multi-faceted concept that originates from two different development paths. One path is the total survey error paradigm that rests on four pillars providing principles that guide survey design, survey implementation, survey evaluation, and survey data analysis. We should design surveys so that the mean squared error of an estimate is minimized given budget and other constraints. It is important to take all known error sources into account, to monitor major error sources during implementation, to periodically evaluate major error sources and combinations of these sources after the survey is completed, and to study the effects of errors on the survey analysis. In this context survey quality can be measured by the mean squared error and controlled by observations made during implementation and improved by evaluation studies. The paradigm has both strengths and weaknesses. One strength is that research can be defined by error sources and one weakness is that most total survey error assessments are incomplete in the sense that it is not possible to include the effects of all the error sources. The second path is influenced by ideas from the quality management sciences. These sciences concern business excellence in providing products and services with a focus on customers and competition from other providers. These ideas have had a great influence on many statistical organizations. One effect is the acceptance among data providers that product quality cannot be achieved without a sufficient underlying process quality and process quality cannot be achieved without a good organizational quality. These levels can be controlled and evaluated by service level agreements, customer surveys, paradata analysis using statistical process control, and organizational assessment using business excellence models or other sets of criteria. All levels can be improved by conducting improvement projects chosen by means of priority functions. The ultimate goal of improvement projects is that the processes involved should gradually approach a state where they are error-free. Of course, this might be an unattainable goal, albeit one to strive for. It is not realistic to hope for continuous measurements of the total survey error using the mean squared error. Instead one can hope that continuous quality improvement using management science ideas and statistical methods can minimize biases and other survey process problems so that the variance becomes an approximation of the mean squared error. If that can be achieved we have made the two development paths approximately coincide.
Research on Behavior of Corrugated Packing in Vacuum Distillation Tower

The corrugated packing is prone to break down easily, which can affect the tower efficiency substantially. It is the inner environment of the vacuum distillation tower including the temperature and chemical nature of fluid that lead to the packing damage. The theoretical analysis indicates that it is the inner material flow of vacuum distillation tower that leads to the vibration of packing, which can affect the corrosion fatigue of packing significantly. Meanwhile, the modal shape and inherent frequency of packing under prestress can be obtained by means of mathematical analysis. Based on the two kinds of analysis, the flow induced vibration and corrosion fatigue are accountable for the failure of packing.
Instantaneous phase-shifting Fizeau interferometry with high-speed pixelated phase-mask camera

A Fizeou interferometer with instantaneous phase-shifting ability using a Wollaston prism is designed. to measure dynamic phase change of objects, a high-speed video camera of 10-5s of shutter speed is used with a pixelated phase-mask of 1024 × 1024 elements. The light source used is a laser of wavelength 532 nm which is split into orthogonal polarization states by passing through a Wollaston prism. By adjusting the tilt of the reference surface it is possible to make the reference and object beam with orthogonal polarizations states to coincide and interfere. Then the pixelated phase-mask camera calculate the phase changes and hence the optical path length difference. Vibration of speakers and turbulence of air flow were successfully measured in 7,000 frames/sec.

High frequency homogenisation for structured interfaces

High frequency homogenisation is applied to develop asymptotics for waves propagating along interfaces or structured surfaces. The asymptotic method is a two-scale approach fashioned to encapsulate the microstructural information in an effective homogenised macroscale model. These macroscale continuum representations are constructed to give solutions near standing wave frequencies and are valid even at high frequencies. The asymptotic theory is adapted to model dynamic phenomena in functionally graded waveguides and in periodic media, revealing their similarities. Demonstrating the potential of high frequency homogenisation, the theory is extended for treating localisation phenomena in discrete periodic media containing localised defects, and for identifying Rayleigh-Bloch waves. In each of the studies presented here the asymptotics are complemented by analytical or numerical solutions, or both.
