Streszczenie:

Using the socio-ecological model, this qualitative study aimed to explore teachers’ perspectives on the barriers and facilitators to Fundamental Movement Skills (FMS) and physical activity engagement in children living in deprived areas in the UK. A purposive sample of 14 primary school teachers participated in semi-structured focus groups drawn from schools situated in lower SES wards and ethnically diverse areas in Central England. Thematic analysis of transcripts identified multiple and interrelated factors across all levels of the socio-ecological model for barriers to FMS and PA (i.e., intrapersonal, interpersonal, organisational, community and policy). Facilitators at three levels of influence were found (i.e., intrapersonal, interpersonal and organisational). We conclude, barriers and enablers to the PA and FMS in children from ethnically diverse backgrounds living in deprived areas are multifactorial and interrelated. At a school level, initiatives to increase PA and develop the FMS needed to be active are likely to be ineffective unless the barriers are addressed at all levels and considered more holistically with their complexity. Multi-disciplinary solutions are needed across sectors given the range of complex and interrelated factors.

The purpose of the current research was to gather baseline data on female youth to inform the development of a targeted physical activity (PA) and sports-based intervention, specifically identified as “Gaelic4Girls”. Cross-sectional data on PA levels, psychological correlates of PA, anthropometric characteristics, and the fundamental movement skill (FMS) proficiency of female youth (n = 331; M age 10.92±1.22) were collected. A subsample (n = 37) participated in focus group (FG) interviews exploring perceptions of health/sport, and identifying barriers/motivators to participation. PA levels were assessed using self-report (PA Questionnaire for Older Children) and classified as low, moderate, and high active. One- and two-way ANOVAs (post hoc Tukey honest significant difference [HSD]) were used to analyze the data. The FGs were transcribed verbatim, coded, and thematically analyzed. Findings indicated that the majority of youth (71.8%) were not meeting the minimum daily PA recommendations for health, and that 98.1% did not achieve the FMS proficiency expected for their age. Low, moderately, and highly active participants differ significantly in terms of overall FMS (p = .03), and locomotor control scores (p = .03). FG findings report fun and friendship as key PA motivators, too much competitiveness as barriers, and positive outside encouragement from family/friends/coaches as facilitators encouraging PA engagement. Findings highlight the need for targeting low levels of PA, FMS proﬁciency in female youth sport interventions, through addressing self-efﬁcacy levels, inclusive of fun, and socially-stimulating PA environments.

The study assessed perception, knowledge, and practices regarding maternal perception of fetal movements (FMs) among women and their healthcare providers in a low-resource setting. Semi-structured interviews, questionnaires and focus group discussions were conducted with 45 Zanzibar women (18 antenatal, 28 postpartum) and 28 health providers at the maternity unit of Mnazi Mmoja Hospital, Zanzibar, Tanzania. Descriptive and thematic analyses were conducted to systematically extract subthemes within four main themes 1) knowledge/awareness, 2) behavior/practice, 3) barriers, and 4) ways to improve practice. Within the main themes it was found that 1) Women were instinctively aware of (ab)normal FM-patterns and healthcare providers had adequate knowledge about FMs. 2) Women often did not know how to monitor FMs or when to report concerns. There was inadequate assessment and management of (ab)normal FMs. 3) Barriers included the fact that women did not feel free to express concerns. Healthcare providers considered FM-awareness among women as low and unreliable. There was lack of staff, time and space for FM-education, and no protocol for FM-management. 4) Women and health providers recognised the need for education on assessment and management of (ab)normal FMs. In conclusion, women demonstrated adequate understanding of FMs and perceived abnormalities of these movements better than assumed by health providers. There is a need for more evidence on the effect of improving knowledge and awareness of FMs to construct evidence-based guidelines for low resource settings.

Background: Pediatric physical inactivity is a major public health concern. According to the 2017 State of Play report, only 24% of youth meet the recommended physical activity (PA) dosage. Previous studies identified fundamental movement skill (FMS) proficiency as a predictor of physical literacy and PA. Mastery of FMS requires direct instruction and practice; however, it is unknown how well FMS are implemented in physical education (PE). Hypothesis/Purpose: To describe FMS practice patterns in the elementary PE curriculum. We had two hypotheses: 1) Fewer PE teachers provide comprehensive FMS instruction in later curriculum (grades 4-6) compared to early curriculum (grades 1-3) and 2) Fewer PE teachers teach FMS with direct instruction methods in later curriculum compared to early curriculum. Methods: A cross sectional survey design was used. PE teachers (grades 1-6) were recruited via electronic mail from various U.S. regions from January 2018 to March 2019. An electronic questionnaire was developed to ask about timing of FMS teaching and method of instruction. Additional questions were asked about methods used to evaluate FMS proficiency, including use of a standardized assessment of gross motor development, referrals and remediation recommended for children who appeared to be falling behind, and perceived barriers to FMS instruction. Chi-square tests (p<0.05) were employed. Results: We collected 87 responses with approximately 9% from West, 42% from Midwest, and 49% from South regions. Among all responses, 54% of PE teachers taught all FMS and 40% taught all FMS with direct instruction. Approximately, 66 % taught all FMS for grades 1-3 compared to 42% for grades 4-6 (p<0.0001). Regarding instruction methods, 47% of teachers for grades 1-3 utilized direct instruction to teach all FMS compared to 27% for grades 4-6 (p=0.0007). Only 3.7% of teachers used a standardized assessment of gross motor development to evaluate FMS proficiency. For children who appeared to be falling behind, 6.7% of teachers reported accepting the child’s “best effort” in participation. Only 7.3% reported referring to an exercise program and no PE teacher sought a healthcare referral. Time was reported as the greatest barrier to improving a child’s FMS competency in 52.4% of responses. Conclusion: Results suggests that fewer PE teachers teach all FMS in late elementary PE curriculum compared to early curriculum. Additionally, fewer teachers utilize direct instruction methods to teach skills in late elementary curriculum. With time reported as the greatest barrier, a more efficient screening tool to evaluate FMS competency may be needed.

Due to rapid globalization and faster growth of world market, there is always a need of modification in the present mode of manufacturing system; these modifications increase the viabilities of manufacturer to move ahead in competitive market. These changes also improve the manufacturer and consumer relation by meeting the latest demand of consumers. The concept of Agile Manufacturing system is the new in era of twenty first which covers the responsive and time saving strategies design and adopted by the manufacturers to dominate the market. Agile Manufacturing system (AMS) proves to be advancement over other manufacturing systems which are like Flexible Manufacturing System (FMS) and Lean Manufacturing System (LMS). Although many industries and companies in India are still in the phase of FMS and still need to cover advance strategies. For this it is needed to identify the barriers which coming in between the implementation of AMS. This paper is based on the Lean and Agile Principles, in which these problems has been tried to remove the barriers. This paper is the effort to identify and remove the barriers with the help of case study.

This research focused on three main teaching methods: case study, simulation, and management games from both theoretical as well as empirical aspects. It explores the use, the benefits, and the barriers of the mentioned teaching methods related to the main management courses from Faculty Members (FMs) perspectives. The empirical investigation was based on a survey of all business departments' faculty members. This study revealed (1) the predominant use of lecturing despite the respondents' engagement in case study, simulation, and management games. It showed that (2) the frequency use of these teaching supports was particularly related to some courses, not systematically, and depended on the faculty member (rank, experience, place of degree). Finally, (3) the main barriers preventing the FMs from using these teaching methods are associated with resources, more than risk and suitability.

Background: Low utilization and poor accessibility of hospital based maternal services in low and middle-income countries (LMIC) are evident and financial barriers is a major bottleneck. Globally, an estimated 600,000 maternal deaths occur yearly with over 90% of these deaths occurring in LMICs. In Kenya, maternal mortality is still relatively high with 362 maternal deaths per 100,000 live births. Gaps in the quality of maternal health services exist due to high costs, poor staffing and inaccessibility. However, Utilization of hospital based maternal services enhances skilled delivery and consequently reduces maternal and child mortalities and morbidities. The aim of this study was to establish the trends of utilization of free maternal services (FMS) before and after implementation in counties of Nyanza, Kenya.Methods: The study adopted an analytical cross-sectional study utilizing mixed methods of data collection. Secondary quantitative data on the rate of utilization between June 2011 and May 2015 was compared. Qualitative data was collected from key informants and focused group discussants. Purposive and simple random sampling were used to select target population. Data was analysed using both parametric and non-parametric statistical methods.Results: In maternal services utilization, Kisumu county recorded the highest 98.7%. Overall, in Nyanza, there was tremendous growth on trends of FMS utilization of 53.4% from 36.7% before implementation of FMS with cases of still births, maternal deaths and neonatal deaths.Conclusion: The upsurge of FMS utilization encouraged skilled birth attendance but also caused enormous constrains to health system and reduced the quality of FMS.

Background A large proportion of children are not able to perform age-appropriate fundamental movement skills (FMS). Thus, it is important to assess FMS so that children needing additional support can be identified in a timely fashion. There is great potential for universal screening of FMS in schools, but research has established that current assessment tools are not fit for purpose. Objective To develop and validate the psychometric properties of a FMS assessment tool designed specifically to meet the demands of universal screening in schools. Methods A working group consisting of academics from developmental psychology, public health and behavioural epidemiology developed an assessment tool (FUNMOVES) based on theory and prior evidence. Over three studies, 814 children aged 4 to 11 years were assessed in school using FUNMOVES. Rasch analysis was used to evaluate structural validity and modifications were then made to FUNMOVES activities after each study based on Rasch results and implementation fidelity. Results The initial Rasch analysis found numerous psychometric problems including multidimensionality, disordered thresholds, local dependency, and misfitting items. Study 2 showed a unidimensional measure, with acceptable internal consistency and no local dependency, but that did not fit the Rasch model. Performance on a jumping task was misfitting, and there were issues with disordered thresholds (for jumping, hopping and balance tasks). Study 3 revealed a unidimensional assessment tool with good fit to the Rasch model, and no further issues, once jumping and hopping scoring were modified. Implications The finalised version of FUNMOVES (after three iterations) meets standards for accurate measurement, is free and able to assess a whole class in under an hour using resources available in schools. Thus FUNMOVES has the potential to allow schools to efficiently screen FMS to ensure that targeted support can be provided and disability barriers removed.

There is a lack of information available for physical education (PE) provision in the early years foundation stage (EYFS), prompting concern about what is currently delivered in schools and the values behind the approaches taken. Using semi-structured interviews, this study investigated educators’ perspectives on the value of PE and physical activity (PA) for EYFS children across England in relation to opportunities for, barriers to, and benefits of PA and PE. This study collected important stakeholder views and can help shape the impact and implementation of fundamental movement skills (FMS) and PA interventions at the EYFS.

Background:The family business is one of Sweden’s most common business forms, making up 90% of all firms and institutions. Also, it accounts for more than a third of GDP. So, it plays a vital role in the economy in Sweden. However, most of the family businesses are relatively small. Purpose:This paper aims to explore and understand the internal growth barriers to the small Swedish family business. Method:A qualitative method inspired by the inductive approach was conducted through semi-structured interviews with five owners of small family businesses in Sweden. The data were analyzed through three steps of general analytical procedure, which are (1) data reduction, (2) data displays, (3) conclusion and verification. Conclusion:This study concludes several internal growth barriers that affect the small Swedish family business: having only revenue goals, long-term growth goals, no written form of goals, family-oriented goals, unawareness of owner to change the firm’s structure during the growth, owner’s tendency to control all activities, owner prefers to keep the business smaller to keep control, the owner has more than one role and task, shortage of competencies and skills, unqualified successors and family members are welcome, lack of robots and Knowledge, owners have another job, different tasks, and roles, family business offers services of high quality that need time, selecting the oldest son to take over regardless of his competencies, employees’ attitude towards obeying a female owner, successors have no interest in taking over, no successors, rivalry among siblings and conflict of their interest, high arguments, different goals of family members from different generations, employ the first non-family member employee, employed more people, fear that non-family employees are less interested in FB or that more employees lead to loss of control, not able to employ more people and finally risk-avoiding behaviour. These barriers resulted in: hindering strategic changes in the needed time, innovation changes in the market obstructed, goals are forgotten, lack of competencies and skills, increases workload and challenges for the male manager, not responding to the market changes quickly, impossible to manage everything effectively, decrease control, not employing needed employees, responsibilities and roles on the owner increase, decrease integrity and harmony in the family, and finally, not developing the products, assisting more customers, and focusing on the growth. Consequently, lead to selling the firm and not keep it for a long time, slow growth, do no maximize potential growth, growth affected negatively, growth hindered, stay in the same size, avoid growth chances, or miss growth opportunities.

Graphitic materials, thanks to the lamellar structure and chemical stability, are of particular interest to realize barriers against the degradation of surface properties induced by water. Many studies showed that water could be a source of degradation of surface properties. To develop a method to overcome the problem related to the deterioration of the surface it is fundamental to study the water- material interaction. For this reason, in this thesis, the water-surface interaction of graphitic- materials and the use of graphitic materials as impermeable barriers against water were explored. Different experimental set up were realized to study the liquid-gas-solid interaction, such as time evolution of the sessile water drop contact angle, captive bubble contact angle and contact angle measurements in a controlled atmosphere. Moreover, a method of deposition of protective graphene-based films using a Meyer rod to apply graphene-inks onto a surface was developed. To understand the intrinsic wettability of graphitic materials a detailed study of the gas-liquid-solid interactions of graphite was conducted in a wide range of experimental conditions. The surface chemical properties and morphology were studied by X-ray photoelectron spectroscopy (XPS), profilometry and atomic force microscopy(AFM), sessile drop contact angle, captive bubble and secondary emission microscopy (SEM). The results of the gas-liquidâ€“surface interaction study indicated that HOPG surface was sensitive to experimental conditions like airborne contamination and the presence of gases. Similarly, a detailed study of the interaction of water with PDMS surface in various experimental conditions (in the air and immersed in water) were conducted. The findings showed that when PDMS was immersed in water, its surface changed. In fact, the volume of air bubbles in contact with the surface of PDMS increased by increasing immersion time in the water. The experimental results indicated that such dynamic evolution of the air bubbles was related to the rearrangement of surface polymer chains via the migration of the polar groups. This phenomenon induced a degradation of the surface properties of PDMS when it is immersed in water. When graphene monolayer was added to PDMS surface, it acted as a barrier against water, suppressing the dynamic evolution of the bubble. We studied the protective properties also of graphene-based films deposited on lead (Pb). We observed that Pb surface degradation occurred when Pb was in contact with a drop of water. The results showed that degradation of Pb surface in contact with water happened very rapidly but graphene-based films, in particular, graphene oxides films, were able to reduce degradation of the surface significantly.

Streszczenie:

Beyond the opportunities offered by nanotechnology research, there is a great need of studies aimed at understanding the harmful effects of general exposure to nanomaterials. My Ph.D. project aimed to be part of this evaluation, focusing on the interaction and the induction of possible toxic effects of two fibrous nanomaterials (asbestos and carbon nanotubes) at two critical internal biological barriers: the pleura and the placenta. The work is carried out by using advanced microscopy (µXRM and XRF) based on synchrotron radiation and other microscopes (SEM and AFM), and also conventional molecular analysis (PCR and Sanger sequencing) and advanced spectroscopic measurements (UV-Raman). We conducted biochemical studies by using the advanced X-Ray microscopy and fluorescence (µXRM and XRF) techniques in order to reveal mechanisms of toxicity in human mesothelial (MeT5A) and placental cell lines (BeWo) exposed to carbon nanotubes (raw-SWCNT, purified- and highly purified-SCWCNT) or asbestos (crocidolite fibres). Other microscopes (AFM, atomic force microscopy and SEM, Scanning Electron Microscope) are added in some experiments, to better investigate the morphology and the cell-nanofiber interactions. The results obtained with the combination of microscopic techniques allowed to reveal similar as well as different toxic mechanisms in the two internal barriers. The cells treated with raw-SWCNT and crocidolite fibres compared to the control showed an severe alteration of iron metabolism, which is maximal in the pleural cells and is clearly related to the presence of iron into the fibre. X-ray microscopy images (absorption and phase contrast imaging) confirm that the toxicity of nanomaterials is characterized by membrane damage with vesicle secretion and filipodia formation. In relation to this toxic mechanism quite complex and still unknown we evaluated the presence of intracellular ferritin in treated cells. The results demonstrated that crocidolite and “raw” carbon nanotubes increase the amount of intracellular ferritin in both cell models, while purified and highly purified carbon nanotubes give values comparable to control. The stimulation is clearly lower in placental cells, clearly linked to a different or lower uptake of fibres in these cells, suggesting that this barrier is less vulnerable than the pleura. We also investigated the genetic effects and genetic predisposition to toxicity of nanomaterials (nanotoxicogenomic). Since we have to learn from asbestos, one study investigates the possible genetic predisposition to develop mesothelioma after asbestos exposure by looking for BAP1 gene mutations in 30 cases of mesothdelioma. Sanger sequencing of BAP1 gene in the 30 patients identified one non-synonymous variant and two intronic variants. While Sanger sequencing of cDNA revealed no alternative splicing due to the nucleotide change for each mutations. In silico mutation analysis was performed in a predicted protein structure of BAP1 protein without any significant possible effect of the amino acid change about exonic mutations of patient 9. Finally, MLPA (Multiplex ligation-dependent probe amplification) analysis revealed no significant copy number variations at exonic level in all samples. The last aim of molecular studies was to test the feasibility of UV-Raman (IUVS beamline, Elettra Synchrotron of Trieste) spectroscopy to reveal epigenetic changes at DNA level after nanomaterial exposure. An oxidative environment has been created in vitro by using carbon nanotubes (raw-SWCNT), which contain some impurity in metal traces (iron), and free radicals OH• (derived from H2O2). In this condition the nucleotides (dATP, dCTP, dGTP and dTTP) result in increased susceptibility to oxidative damage. The results demonstrated that UV-Raman spectroscopy is useful to reveal the chemical changes that affect the nitrogenous bases after nanomaterials exposure, providing a “fingerprint” of the oxidative DNA damage.

Streszczenie:

In this thesis, four different Machine Learning models and algorithms have been evaluated in the work of classifying Traffic Control Plans in the City of Helsingborg. Before a roadwork can start, a Traffic Control Plan must be created and submitted to the Traffic unit in the city. The plan consists of information regarding the roadwork and how the work can be performed in a safe manner, concerning both road workers and car drivers, pedestrians and cyclists that pass by. In order to know what safety barriers are needed both the Swedish Association of Local Authorities and Regions (SALAR) and the Swedish Transport Administration (STA) have made a classification of roads to guide contractors and traffic technicians what safety barriers are suitable to provide a safe workplace. The road classifications are built upon two rules; the amount of traffic and the speed limit of the road. Thus real-world problems have shown that these classifications are not applicable to every single case. Therefore, each roadwork must be judged and evaluated from its specific attributes. By creating and training a Machine Learning model that is able to determine if a rigid safety barrier is needed or not a classification can be made based on historical data. In this thesis, the performance of several Machine Learning models and datasets are presented when Traffic Control Plans are classified. The algorithms used for the classification task were Random Forest, AdaBoost, K-Nearest Neighbour and Artificial Neural Network. In order to know what attributes to include in the dataset, participant observations in combination with interviews were held with a traffic technician at the City of Helsingborg. The datasets used for training the algorithms were primarily based on geographical data but information regarding the roadwork and period of time were also included in the dataset. The results of this study indicated that it was preferred to include road attribute information in the dataset. It was also discovered that the classification accuracy was higher if the attribute values of the geographical data were continuous instead of categorical. In the results it was revealed that the AdaBoost algorithm had the highest performance, even though the difference in performance was not that big compared to the other algorithms.

This chapter examines maize productivity, technology use in maize, and the impact of non-farm income (NFI) on agricultural investment in Kenya, giving them a gender dimension. The study first concludes that there are no significant differences in maize yields between male-managed farms and female-managed farms (FMFs) in the study areas, Nyeri and Kakamega. Second, technology use for maize production was lower and significant in some instances for FMFs. Significant differences, especially in the use of hybrid seeds and tractor ploughs, were noted. A third conclusion is that NFI is not used in farm investment. NFI had negative coefficients on adoption and intensity of agricultural input use. Policies that encourage both farm and non-farm income should be instituted given the complementary roles that they play. Any entry barriers for disadvantaged households, especially for the FMFs, to participate in higher-paying non-farm activities need to be overcome.

This chapter argues that while the Federal Music Project (FMP) and WPA Music Program in the American West reflected many of the societal prejudices of the day, it was the New Deal emphasis on inclusion that distinguishes the musical productions within a historical context. Indeed, participation bridged many previous barriers and included black as well as white; men as well as women; poor and not; conservative, liberal, and radical; symphonic orchestras and orquestas tipicas; African American spirituals; folksong; satirical political revues; and the range of musical expression. These cross-cultural presentations most often found origin as grassroots ventures and were encouraged by a presidential administration that enthusiastically embraced its constitutionally mandated responsibility to “promote the general welfare” within a society where each citizen is assured of his or her own pursuit of happiness.

AbstractChapter 7 deals with the fish guidance structures (FGS) with narrow bar spacing and focuses on both vertically inclined and horizontal bar racks as well as vertically inclined perforated plate with bypass systems. These FGSs are physical barriers and placed in front of a water intake with either vertical or horizontal angle to the flow direction. They protect fish from entering the water intakes and guide them to the bypass systems and hence into the tailwater. They are suitable for small-to-medium size hydropower plants with design discharge less than 120 m3/s. In the following, different types of FGSs with narrow bar spacing are introduced and their fish guidance performance, head loss prediction and design recommendations presented.

Globally, the construction industry (CI) is regarded as one of the largest consumers of raw materials and natural resources. The industry is also known to be a major source of pollution, waste, and other adverse environmental issues within the built environment. It is therefore imperative to introduce strategies, processes, materials, and technologies that have the potential to revolutionize the CI to a sustainable state, especially in this fourth industrial revolution (4IR) era. Futuristic building materials (FBMs) are the generation of novel and cutting-edge materials with significant potential to solve ongoing challenges and address environmental issues attributed to the CI. Hence, the objective of this paper is to evaluate the hindrances to the utilization of FBMs in realizing a sustainable CI in South Africa. The quantitative research approach was employed in this study. A structured questionnaire survey was administered to construction professionals in the South African construction industry (SACI). Data collected were analyzed using a descriptive statistical method and exploratory factor analysis. Findings from the study revealed the impact of the 15 barriers identified in the reviewed literature. The study also revealed a lack of awareness, lack of knowledge, shortage of skills, poor economic conditions, and escalating costs of building materials as the major barriers hindering the adoption of FBMs. In conclusion, the availability, and accessibility of FBMs are discovered to be limited in the SACI. Research and development (R&D), awareness creation, and multi-disciplinary collaboration is recommended to maximize the effectiveness of FBMs for a sustainable and innovative SACI.

Abstract Functionally graded materials (FGMs) are advanced class of composite materials which can be used as the thermal barrier to protect inner components from the outside high temperature environment. In FGMs, the volume fraction of each constituent can be tailored made across the thickness for desired applications. In this work, the simulation of FGMs in pipes is considered. Despite the wide application of pipes in machinery, those pipes would suffer from many safety problems, such as thermal stress, cavitation, fracture etc. Application of FGMs to the piping systems could lead to some new solutions accounting for safety measures and higher service life. However, the complex phenomena within the fluid structure interaction are hard to describe with the theoretical solution. The visualization of results from simulation will be helpful in understanding the distribution of kinds of physical quantities within the concerned model. For the simulation, FGMs are modeled as the layered structure in the standard finite element method (FEM) package based on FGM constituent law. The free vibration of the FG pipe is simulated and the accuracy of layered model is verified by numerical calculations. Further, based on the layered model, conjugate heat transfer simulations in a heat exchanger with FGMs are conducted.

Abstract Functionally graded materials (FGMs) offer solutions to such engineering problems involving multi-layer systems with large differences in CTE, i.e. thermal barrier coatings, by allowing for a continuous change in the properties over a defined distance, thus minimizing sharp interface effects. By its nature, plasma spraying is well suited to the fabrication of FGMs. However, in order to achieve optimal performance from the material it is necessary to ensure the FGM is uniform in its compositional variation. The deposition efficiency of the particulate species as well as their trajectories will determine the degree of homogeneity of the FGM. It is therefore important that the inter-relationships between the particle size distributions, injection orientation and feed rates are determined. Towards this end, a series of investigations have been carried out to determine the effects of injection orientation on the particle segregation. Analysis of the particle segregation as a function of particle size distribution was then examined in the formation of FGMs. The results indicate that optimal deposition occurs when the various particle species trajectories converge as they approach the substrate.

Abstract As the core component and the first safety barrier of a nuclear power plant, the structural integrity of fuel assemblies (FAs) is an important factor in ensuring the safety of nuclear power. Safety analysis and evaluation of fuel assemblies under seismic conditions is a requirement of nuclear power plant design codes and safety reviews. The mechanical properties of a single FA determine the operational and seismic performance of the core fuel assembly. Due to the complexity of the FAs in terms of structure and boundary conditions, test is the most common method to obtain the mechanical properties. In order to predict the mechanical properties of the fuel assembly, a nonlinear finite element detailed model was developed. The contact and frictional behavior between the fuel rod cladding and the spring/dimple convexity were considered in the modeling to simulate the nonlinear behavior of the fuel rod better. To verify the validity of the model, virtual tests of lateral stiffness test, forced vibration test and impact test were conducted on the model. The comparison with the experimental results shows that the model can reflect the mechanical properties of the fuel assembly well. The modeling method and calculation conclusions in this paper are of guidance for fuel assembly design.

Streszczenie:

In this paper we consider the general fracture problem of a functionally graded thermal barrier coating (TBC) bonded to a substrate. Functionally Graded Materials (FGMs) used in TBCs are usually made from ceramics and metals. Ceramics provide thermal and corrosion resistance while metals provide the necessary fracture toughness and heat conductivity. The volume fractions of the constituents will usually vary from 100% ceramic at the surface to 0% at the interface continuously providing seamless bonding with the metal substrate. To study the general fracture problem in the TBC we consider an arbitrarily oriented crack in an FGM layer bonded to a half plane. The elastic properties of the FGM layer are assumed to vary exponentially, while those of the half plane are homogeneous. The elastic properties are continuous at the interface. As shown in [1], then the governing elasticity equations become partial differential equations with constant coefficients. Using the transform technique, and defining the crack surface displacement derivatives as the unknown auxiliary functions, the mixed-mode crack problem is reduced to a system of Cauchy type singular integral equations. It is shown that at the crack tips the stresses still possess the regular square-root singularity, making it possible to use the classical definition of stress intensity factors. The singular integral equations are solved numerically using a Gaussian type quadrature and the mode I and mode II stress intensity factors are calculated for various crack lengths and crack orientations. Also the crack surface displacements are computed for different crack inclinations. It is observed that the crack orientation, crack length and the nonhomogeneity parameter affect the stress intensity factors significantly.

The purpose of this effort is to describe a database containing information about the strength and toughness of steel used in existing hydraulic steel structures (HSS). The lack of information about these properties often presents a barrier to conducting fitness for service (FFS) analysis. The statistical dependence between strength and toughness variables and other database fields is evaluated to assess their potential as predictive variables.

Streszczenie:

The FSA and FSS have become aware of the use of recycled plastic food contact applications that are in part, or fully, fulfilled using so called “ocean-bound” plastic. As this term has been observed to be a relatively new concept in food contact applications a full review of whether plastic material sourced from the open environment (ocean, ocean-bound, land) can be utilised in food packaging, either directly or behind a functional barrier, is currently being undertaken by the FSA. As part of its full review, the FSA and FSS invites submissions from industry, the individuals as consumers, or interested parties, including those with the relevant science expertise to submit evidence on this issue. We are particularly interested in understanding how operators propose to, or currently, carry out their own risk assessment of the safe use of these materials as a food contact material, particularly when sourcing from countries whose regulatory standards and waste management strategies differ to those of the UK and/or information on previous use and/or misuse are less certain. In addition, we would like to know how full traceability along the supply chain is ensured.
