Abstract:
One common approach to test sequence generation for structurally testing concurrent programs involves constructing a reachability graph (RG) and selecting a set of paths from the graph to satisfy some coverage criterion. It is often suggested that test sequence generation methods for testing sequential programs based on a control flow graph (CFG) can also be used to select paths from an RG for testing concurrent programs. However, there is a major difference between these two, as the former suffers from a feasibility problem (i.e., some paths in a CFG may not be feasible at run-time) and the latter does not. As a result, even though test sequence generation methods for sequential programs can be applied to concurrent programs, they may not be efficient. We propose four methods — two based on hot spot prioritization and two based on topological sort — to effectively generate a small set of test sequences that covers all the nodes in an RG. The same methods are also applied to the corresponding dual graph for generating test sequences to cover all the edges. A case study was conducted to demonstrate the use of our methods.

Abstract:
The mitochondrial DNA (mtDNA) D-loop of endangered and critically endangered breeds has been studied to identify maternal lineages, characterize genetic inheritance, reconstruct phylogenetic relations among breeds, and develop biodiversity conservation and breeding programs. The aim of the study was to determine the variability remaining and the phylogenetic relationship of Martina Franca (MF, with total population of 160 females and 36 males), Ragusano (RG, 344 females and 30 males), Pantesco (PT, 47 females and 15 males), and Catalonian (CT) donkeys by collecting genetic data from maternal lineages. Genetic material was collected from saliva, and a 350 bp fragment of D-loop mtDNA was amplified and sequenced. Sequences were aligned and evaluated using standard bioinformatics software. A total of 56 haplotypes including 33 polymorphic sites were found in 77 samples (27 MF, 22 RG, 8 PT, 19 CT, 1 crossbred). The breed nucleotide diversity value (π) for all the breeds was 0.128 (MF: 0.162, RG: 0.132, PT: 0.025, CT: 0.038). Principal components analysis grouped most of the haplogroups into two different clusters, I (including all haplotypes from PT and CT, together with haplotypes from MF and RG) and II (including haplotypes from MF and RG only). In conclusion, we found that the primeval haplotypes, haplogroup variability, and a large number of maternal lineages were preserved in MF and RG; thus, these breeds play putative pivotal roles in the phyletic relationships of donkey breeds. Maternal inheritance is indispensable genetic information required to evaluate inheritance, variability, and breeding programs.

Abstract:
The many quantitative traits of interest to plant breeders are often genetically correlated, which can complicate progress from selection. Improving multiple traits may be enhanced by identifying parent combinations – an important breeding step – that will deliver more favorable genetic correlations (rG). Modeling the segregation of genomewide markers with estimated effects may be one method of predicting rG in a cross, but this approach remains untested. Our objectives were to: (i) use simulations to assess the accuracy of genomewide predictions of rG and the long-term response to selection when selecting crosses on the basis of such predictions; and (ii) empirically measure the ability to predict genetic correlations using data from a barley (Hordeum vulgare L.) breeding program. Using simulations, we found that the accuracy to predict rG was generally moderate and influenced by trait heritability, population size, and genetic correlation architecture (i.e., pleiotropy or linkage disequilibrium). Among 26 barley breeding populations, the empirical prediction accuracy of rG was low (-0.012) to moderate (0.42), depending on trait complexity. Within a simulated plant breeding program employing indirect selection, choosing crosses based on predicted rG increased multi-trait genetic gain by 11–27% compared to selection on the predicted cross mean. Importantly, when the starting genetic correlation was negative, such cross selection mitigated or prevented an unfavorable response in the trait under indirect selection. Prioritizing crosses based on predicted genetic correlation can be a feasible and effective method of improving unfavorably correlated traits in breeding programs.

Abstract:
Abstract Middepth, time-mean circulation in the western North Pacific Ocean (28°–45°N, 140°–165°E) is investigated using drift information from the profiling floats deployed in the Kuroshio Extension System Study (KESS) and the International Argo programs. A well-defined, cyclonic recirculation gyre (RG) is found to exist north of the Kuroshio Extension jet, confined zonally between the Japan Trench (∼145°E) and the Shatsky Rise (∼156°E), and bordered to the north by the subarctic boundary along ∼40°N. This northern RG, which is simulated favorably in the eddy-resolving OGCM for the Earth Simulator (OFES) hindcast run model, has a maximum volume transport at 26.4 Sv across 159°E and its presence persists on the interannual and longer time scales. An examination of the time-mean x-momentum balance from the OFES hindcast run output reveals that horizontal convergence of Reynolds stresses works to accelerate both the eastward-flowing Kuroshio Extension jet and a westward mean flow north of the meandering jet. The fact that the northern RG is eddy driven is further confirmed by examining the turbulent Sverdrup balance, in which convergent eddy potential vorticity fluxes are found to induce the cyclonic RG across the background potential vorticity gradient field. For the strength of the simulated northern RG, the authors find the eddy dissipation effect to be important as well.

Abstract:
The purpose of the current study was to evaluate the transferability of 2 different resistance training protocols on service velocity and its precision consistency in junior tennis players. Thirty-six male athletes (15.03 ± 1.64 years) were randomly assigned to a machine-based resistance-training group (RG, n = 12), a plyometric training group (PG, n = 12), and a control group (CG, n = 12). For a period of 8 weeks, both intervention groups resistance trained 2 days per week in addition to their regular tennis training, whereas the CG had no extra training. Mean service velocity over 20 maximum-velocity serves increased significantly more in PG (3.78%; p < .05) when compared with CG, whereas no such changes could be found in the RG (1.18%; p > .05). Service precision did not change from pre- to posttest in all three groups (p > .05). Only the plyometric training program tested, improved mean service velocity over 20 maximum-velocity serves in junior tennis players but did not affect service precision.

Abstract. The study covered 11 376 horses registered in the six successive volumes of the Wielkopolski Herdbook. The level of variability in the body conformation indices and in the performance value indices was analysed. The genetic basis parameters for the body conformation and performance traits of the Wielkopolski horses were assessed. A high level of heritability was identified for the wither height (h2 = 0.566) and cannon circumference (h2 = 0.418), with an average heritability level of the other analysed characteristics (ranging from h2 = 0.205 – for the stallion performance test results to h2 = 0.350 – in the case of chest circumference). On the other hand, genetic correlation between the analysed indices produced the highest values for the relationship between wither height and cannon (rG = 0.636) and chest (rG = 0.551) circumference, as well as for the interrelation between the above dimensions and the following body structure indices: »boniness« (rG = 0.690) and »bulkiness« (rG = 0.541). Considering the extensive scope of the study – and the fact that the breed population was registered in the Wielkopolski Herdbook – the authors suggested the advisability of using the results of the present study for the modification of breeding programs with a view to improve the breed in question, both its principal population and the one included in the program of gene-pool protection.

Abstract:
AbstractIn breeding programs, the variations and relationships among main traits need to be understood to develop selection and breeding strategies. Resin is considered as one of most important non-timber production of P. massoniana which can privides terpenes used in the chemical industry. The present study assessed the genetic variations in growth, morphologic traits, and resin yield, as well as the phenotypic and genetic correlations between these traits of 45 half-sib families of eight-year-old Pinus massoniana trees. All traits show highly significant family effects. The individual heritability for diameter at breast height (DBH) was the highest (hi2=0.55). Heritabilities for resin yield, tree height, crown depth, and the height to the live crown were slightly lower than DBH, ranging from 0.32 to 0.45. The other traits were under weak genetic control and heritabilities ranged from 0.17 to 0.20. All growth and morphologic traits were significantly correlated genetically with resin yield. Number of living branches had the highest genetic correlation with resin yield (rg=0.99), followed by DBH and number of living whorls (rg=0.73 and 0.70). Only a moderate positive genetic correlation with resin yield was found with the other traits (rg=0.47-0.57), except for height under the living branches (rg=-0.45). The results of this study indicate that both resin yield and growth can be improved simultaneously in the next generation. Of the traits assessed DBH was the optimum trait for indirectly selecting high-yielding resin trees.

Abstract:
Introduction: Rhythmic gymnastics (RG) is a sport that combines art biomechanical gestures of high complexity, which requires a high level of development of physical qualities such as agility, flexibility, strength, impulsion and dexterity. In this modality studies show that injuries are attributed more articulate knees, ankles, and in some cases ends wrist sprains being the most frequently recorded in athletes in competition level. Therefore, proprioception and muscle control play a fundamental role in dynamic joint stability, since after orthopedic injuries sensorimotor some characteristics are altered and should be focused on rehabilitation programs to get a better return so the activities prior to the injury. Objective: The objective of this project is to evaluate the effect of proprioceptive training on postural balance of athletes in rhythmic gymnastics - RG, from the use of a force platform BIOMEC400 (EMG System do Brazil, Ltda SP). Method: We performed a proprioceptive training in thirty days, in two stages, moving the complexity of the exercises each phase proprioceptive training. Results: We observed that there was a significant improvement in results of training, when it was used more complex exercises and agility exercises before. Conclusion: Because it is athletes RG high performance and present a predominance of activities in one foot, protocols proprioception should be more intensively, generating a higher level of disturbance and postural imbalances.

Abstract:
AbstractA firm understanding of the genetic relationships among wood properties is a prerequisite for breeding for higher wood quality in Pinus elliottii families. To examine and deal with such relationships, increment cores were sampled at breast height from 1260 trees in 42 open-pollinated families in three 27-year-old Slash pine progeny trials in southern China, and genetic variation, genotype-by-environment (G × E) interaction, genetic correlation and correlated response were investigated. The basic density (BD), dynamic modulus of elasticity (MOED) and tracheid traits were found to be under moderate to strong genetic control for the three locations combined, with individual narrow-sense and family mean heritability ranging from 0.28 to 0.44 and 0.52 to 0.69, respectively. Type B genetic correlation estimates indicated that the G × E interaction had a small-level influence on wood properties. Strong genetic correlations (rg) were found between BD and MOED at the three sites (rg = 0.46–0.85), and BD or MOED showed moderate to strong correlations with most tracheid traits at specific localities. In tree breeding programs, one possible strategy would be to improve pulpwood quality and the strength of structural wood through selection for different wood quality traits.

Abstract:
News interviews are core within current practices of journalism. They point to the existence of a mediated public space and bolster the concept of democratic accountability. This research investigates what impact these concepts have on the news interviews broadcast by the Today programme (BBC Radio 4) and how interaction within them invoked the public. The programme has a responsibility to uphold the democratic life of the UK, making it a compelling focus of research. The case study examined in this thesis is the broadcast of news interviews concerning the Human Fertilisation and Embryology Act 2008 (HFEA 2008) and how they shaped representations of the biomedical techniques contained within the legislation. In particular, research investigated what the news interviews reveal about the biological citizen: a specific configuration of citizenship increasingly important in the twenty first century. The research method is Conversation Analysis and the news interviews as broadcast are the empirical data on which findings are based. The study contributes to the understanding of the method through the investigation of the structural organisation of the news interviews and how this affected interaction. Findings suggest that the news interviews on the Today programme highlights the political dimensions of the HFEA 2008, that interviewees were predominantly MPs or public figures and that the gender ratio is skewed towards male voices. It points to the fact that the programme prefers news interviews that contain two interviewees, as this promotes adversarial encounters within interaction. Research also establishes how interviewers have at their disposal a range of devices, such as third party citations, which they use within questions in order to achieve a neutral posture. A further set of findings uncovers the need of interviewees to maintain a positive image of themselves, employing politeness strategies in order to co-operate when answering a question.

Title: Development of flexibility and subsequent compensation at various performance levels in rhythmic gymnastics in the Czech Republic Objectives: The aim of the thesis is to find out how exercises for the development of flexibility are performed. The other aim is to find out how the girls are led to correct warm-up and compensation during the training and at home. Interviews with trainers of various levels of rhythmic gymnastics were used to gather information. Furthermore, the thesis compares training routines for the flexibility development between different levels of rhythmic gymnastics programs. Methods: Information was obtained from interviews with trainers of rhythmic gymnastics in the Czech Republic. These were then analyzed. Some questions were evaluated using statistical methods of quantitative research. Results: Three out of five hypotheses were confirmed, remaining two were not confirmed. The biggest differences were found between the free program and the other two programs. The main difference concerned the length of the training units and other different answers arose from this. All or most of the trainers agreed on some issues regardless of the level at which they work. Keywords: Flexibility, Development, Compensation, Rhythmic gymnastics, Programs of RG, Imbalance,

Abstract:
From the backgrounds of an external counsel and an in-house lawyer, this chapter offers a legal perspective on responsible gambling (RG). The primary tool of lawyers is law and not empirical sciences. Accordingly, these legal scholars explain how their normative perspective differs from other scholarly perspectives and how it affects the concept, theory, and objectives of RG. These stakeholders describe aspects that hamper the effectiveness of RG policies, such as hidden agendas and RG rules that are not empirically based. They then revisit the Reno Model, comparing its strengths and weaknesses; they observe alternative models of regulatory practice. The analytical exercise feeds into discussions of the legal and practical implications of the RG rules, in particular as regards the scope of duty of care and the compliance burden of regulated gambling operators. The authors make suggestions on how to improve RG programs and the Reno Model itself, using insights from behavioral studies and promoting bottom up-initiatives.

Full text
Abstract:
In a series of Commission papers, the U.S. Nuclear Regulatory Commission (NRC) described its policy for inservice testing (IST) programs to be developed and implemented at nuclear power plants licensed under 10 CFR Part 52. This paper discusses the expectations for IST programs based on those Commission policy papers as applied in the NRC staff review of combined license (COL) applications for new reactors. For example, the design and qualification of pumps, valves, and dynamic restraints through implementation of American Society of Mechanical Engineers (ASME) Standard QME-1-2007, “Qualification of Active Mechanical Equipment Used in Nuclear Power Plants,” as accepted in NRC Regulatory Guide (RG) 1.100 (Revision 3), “Seismic Qualification of Electrical and Active Mechanical Equipment and Functional Qualification of Active Mechanical Equipment for Nuclear Power Plants,” will enable IST activities to assess the operational readiness of those components to perform their intended functions. ASME has updated the Operation and Maintenance of Nuclear Power Plants (OM Code) to improve the IST provisions for pumps, valves, and dynamic restraints that are incorporated by reference in the NRC regulations with applicable conditions. In addition, lessons learned from performance experience and testing of motor-operated valves (MOVs) will be implemented as part of the IST programs together with application of those lessons learned to other power-operated valves (POVs). Licensee programs for the Regulatory Treatment of Non-Safety Systems (RTNSS) will be implemented for components in active nonsafety-related systems that are the first line of defense in new reactors that rely on passive systems to provide reactor core and containment cooling in the event of a plant transient. This paper also discusses the overlapping testing provisions specified in ASME Standard QME-1-2007; plant-specific inspections, tests, analyses, and acceptance criteria; the applicable ASME OM Code as incorporated by reference in the NRC regulations; specific license conditions; and Initial Test Programs as described in the final safety analysis report and applicable RGs.

Abstract:
In general, Rg Value, Y value and holiday density can be used to evaluate the performance of the coating deposited on the buried steel pipelines. However, the evaluation may be misleading when a single parameter is used. A new combination method for assessing the performance of the coating on the steel pipelines is developed in this paper. Using this approach, Rg Value, Y value and holiday density play appropriate role on the assessment. Some new modules are presented in this approach, including current distributary module, holiday module, intelligent critical curve of AC attenuation. Additionally, a computer program is compiled that can finish data processing of AC attenuation automatic, and the result report can be synchronously printed.

Full text
Abstract:
Appendix J of 10 CFR 50, “Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors,” sets the testing requirements for preoperational and periodic verification of the leak-tight integrity of the primary reactor containment, including systems and components which penetrate containment of light water-cooled power reactors, and establishes the acceptance criteria for such tests. The purposes of the tests are to assure that leakage through the primary reactor containment and systems and components penetrating primary containment would not exceed allowable leakage rate values as specified in the plants’ technical specifications. The current Appendix J requirements provide two options for performing the tests. Option A (fully deterministic) requires that after the preoperational leakage rate tests, a set of three integrated leak rate tests (ILRT — termed as Type A tests) shall be performed, at approximately equal intervals during each 10-year service period. Option B does not provide a quantitative requirement for scheduling the periodic Type A tests. However, NEI 94-01, “Industry Guideline for Implementing Performance-Based Option of 10 CFR Part 50, Appendix J,” and NRC Regulatory Guide (RG). The containment is a vital engineering safety feature of a nuclear power plant. It encloses the entire reactor and reactor coolant system and serves as a final barrier against the release of radioactive fission products to the environment under various accident conditions. Containment design is based on pressure and temperature loadings associated with a loss-of-coolant-accident resulting from a double-ended rupture of the largest pipe in the reactor coolant system. Recently, it has been reported that in certain 1.163, “Performance-Based Containment Leak Test Program,” provide guidelines for determining the frequencies of preoperational and periodic leak rate tests using a performance based approach. The Option B requirements and NEI 94-01 guidance are based on NUREG-1493, “Performance Based Containment Leak-Test Program.” Based on the information provided by the operating data and their risk significance, the study calculated the change in risk (in person-rem) to public for the 15 alternatives considered in the study. However, recognizing the non-sensitivity of risk to change in Type A leak rate testing frequencies, as depicted in NUREG-1493, a number of licensees are proposing changes to their Type A test frequencies using NRC risk-informed guidance in RG 1.174, “An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis.” The paper discusses certain key deterministic aspects of the risk-informed decision for the plant-specific changes in the ILRT frequencies.

Abstract:
PAVAN is an atmospheric dispersion program for evaluating design basis accidental releases of radioactive materials from nuclear power plant. It was developed by Pacific Northwest Laboratory on the basic of the atmospheric dispersion models described in RG 1.145 by NRC (U.S. Nuclear Regulatory Commission). Using the joint frequency of wind direction, wind speed and atmospheric stability, the atmospheric relative concentration values for the exclusion area boundary and outer LPZ boundary of nuclear power plant are calculated and given by the program. Once the program was introduced, it has been widely used in the radioactive accident consequence assessment, especially in the FSAR (Final Safety Analysis Report) and Report of EIA (Environmental Impact Assessment) of NPPs in China. The theory basis and general method of PAVAN is introduced in this paper. And specialty of the X/Q points based on joint frequency data is discussed. The envelope algorithm of PAVAN is also introduced and discussed. The paper presents an improved algorithm based on PAVAN which uses the hourly meteorological data as input instead of joint frequency data. In this algorithm, the size of X/Q points is related to the quantity of the hourly meteorological data. When the quantity is large enough, e.g. 17520 sets of hourly meteorological data in two years, the envelope curve for X/Q points fit more exactly than PAVAN. Using the observed meteorological data, the improved algorithm is compared with PAVAN. The result proves that the former is more accurate. In general, the improved algorithm is relatively conservative. In some situation, the conservativeness is not certain. The factors which result in the uncertainty are deeply discussed. Further optimized are performed by the algorithm. The number of points to seek in envelope curve fitting is set to be dynamic and be a quarter of total number of X/Q points to be fitted. The result shows that increasing the number of points to seek in the iteration process of envelope curve fitting will lead to more conservative X/Q values. Additionally, the optimized algorithm provides X/Q value of 50% probability level for overall site. The value is not relatively conservative. From the standpoint of statistical probability, it is more realistic and is acceptable for potential accident consequence assessment. Especially, when X/Q value of 95% probability level for overall site is too conservative to accept, the value of 50% probability level can be used to replace the conservative value.

Abstract:
The direct-fired supercritical CO2 (sCO2) cycle is currently considered as a zero-emission power generation concept. It is of interest to know how to optimize various components of this cycle using computational tools, however, a comprehensive effort on this area is currently lacking. In this work, the behavior of thermal properties of sCO2 combustion at various reaction stages has been investigated by coupling real gas CHEMKIN (CHEMKIN-RG) with an in-house Premixed Conditional Moment Closure (PCMC) code and the high pressure Aramco-2.0 kinetic mechanism. Also, the necessary fundamental information for sCO2 combustion modelling is reviewed. The Soave-Redlich-Kwong equation of state (SRK EOS) is identified as the most accurate EOS to predict the thermal states at all turbulence levels. Also, an empirical model for the compression factor Z is proposed for sCO2 combustors, which is a function of mixture inlet conditions and the reaction progress variable. This empirical model is validated between the operating conditions 250–300 bar, inlet temperatures of 800–1200 K and within the current designed inlet mole fractions and the accuracy is estimated to be less than 0.5% different from the exact relation. For sCO2 operating conditions the compression factor Z always decreases as the reaction progresses and this leads to the static pressure loss between inlet and exit of the sCO2 combustor. Further, a review of high pressure viscosity and thermal conductivity models of mixtures and pure-components are presented from the literature and suggestions are made for their adoptability in sCO2 combustor simulations. The thermal properties such as specific heats, speed of sound, pressure exponent and isothermal compressibility are accurately quantified.
