Abstract:
To reduce the emission of carbondyoxide (CO2) of combustion engines, liquefied naturalgas (LNG) is used as an alternative fuel. LNG is transported via truck, ship or railway for longdistances. Double walled stainless steel tanks are used for transportation, which are heavy and expensive.The vacuum insulation between the two walled structure ensures that the LNG stays liquid overthe transportation time (boiling point of LNG: −162 °C). This causes a high temperature differencebetween the transported good and the ambient air. A simplified tank construction is used to reduce the weight and price of the tank. Instead of stainlesssteel, glass fiber reinforced plastic (GFRP) is used. The designed is changed to a single walledconstruction with a solid insulation material outside on the GFRP structure. Goal of this work is the characterization of a suitable insulation material and configuration as wellas the analysis of the mechanical properties of GFRP under cryogenic conditions. Several experimentsare carried out. Numerical models of these experiments can then be used for parameter studies.

Abstract:
The scaled swine farms have been developed rapidly in China since 21stcentury, which bring serious problem in environmental pollution, especially in winter. In order to s reduce the pollution from intensive scaled swine farms, as well as produce biogas in winter, a technological route was put forward to control the sewage pollution in swine farm by using bio-tank of glass fiber reinforced plastics (GFRP). The experiments in swine farm of FuJian Hua Feng Co. Ltd in Nanping city showed that the developed technology had achieved zero-draining, which was able to solve the pollution problem and produce biogas in winter. The sewage temperature of bio-tank of GFRP increased average 1.18°C more than that of bio-tank of reinforced concrete. And the average biogas-generating rate of bio-tank of GFRP of year 2009 was 0.45 m3·m-3·d-1, which increased 28% more than that of reinforced concrete. The indexes of COD, BOD, SS, NH3-N, and TP for the out-let wastewater of the treatment were 579.1 mg·L-1, 237.7 mg·L-1, 289.8 mg·L-1, 319.4 mg·L-1and 31.7 mg·L-1, respectively.

Abstract:
O termo neuroplasticidade se refere às mudanças funcionais ou anatômicas que ocorrem no sistema nervoso decorrentes de experiências. O enriquecimento ambiental (EA) é um dos modelos experimentais utilizados para estudar eventos relacionados à neuroplasticidade, pois aumenta a neurogênese, os níveis de neurotrofinas, a sobrevivência neuronal, a sinaptogênese, além de induzir cascatas de sinalização e uma mudança na arborização dendritica dos neurônios de diversas regiões encefálicas. Nos últimos anos a importância dos astrócitos tem ganho destaque, principalmente no que tange a sua capacidade de modular sinapses e na participação ativa em eventos plásticos no encéfalo, essas mudanças estão relacionadas a alterações funcionais e morfológicas. O EA é um modelo interessante para avaliar performances comportamentais pois é um modelo que ocasiona mudanças na capacidade de armazenar e acessar novas informações. Sendo assim, acreditamos que o EA é capaz de gerar efeitos plásticos nos astrócitos do Stratum Radiatum da região CA1 e alterar as respostas comportamentais a tarefa de reconhecimento de objetos. Após oito semanas de EA iniciado logo após o desmame, camundongos CF-1 albinos não apresentam diferenças significativas no número de astrócitos GFAP-ir e na densidade óptica para GFAP no Stratum Radiatum. Entretanto ocorreu um aumento no número de processos originários do soma, aumento no tamanho destes processos no eixo lateral, paralelo as colaterais de Schaffer e no número de intersecções aos círculos concêntricos de Scholl na mesma região. Os astrócitos adquirem um formato estrelado, este achado pode estar relacionado ao aumento da densidade sináptica nesta região e corroboram com a idéia de que modificações astrocitárias são parte ativa dos processos plásticos que ocorrem no encéfalo. Nossos resultados mostraram também uma mudança comportamental na resposta a tarefa de reconhecimento de objetos. Os animais expostos ao EA despendem menos tempo explorando os objetos, tanto familiar como não familiar e apresentam igual capacidade de discriminar os objetos. Estes resultados demonstram um comportamento mais propicio a sobrevivência da espécie em animais expostos ao EA, o que inclui uma rápida exploração e um possível aumento na capacidade de aprender sobre o ambiente.
Environmental enrichment (EE) induces plastic changes in the brain, including morphological changes in hippocampal neurons, with increases in synaptic and spine densities. In recent years, the evidence for a role of astrocytes in regulating synaptic transmission and plasticity has increased, and it is likely that morphological and functional changes in astrocytes play an important role in brain plasticity. In others hand EE is used to investigate behavioral modifications associated with gene-environmental interaction. Our study was designed to evaluate changes in astrocytes induced by EE in the hippocampus, focusing on astrocytic density and on morphological changes in astrocytic processes and the performance in object recognition task (ORT) for evaluate animals ability to learn about their environment. After 8 weeks of EE starting at weaning, CF-1 mice presented no significant changes in astrocyte number or in the density of glial fibrillary acidic protein immunoreactivity (GFAP-ir) in the Stratum Radiatum. However, in the same region occur significant increase in the ramification of astrocytic processes, as well as by an increase in the number and length of primary processes extending in a parallel orientation to CA1 nerve fibers. This led astrocytes to acquire a more stellate morphology, a fact which could be related to the increase in hippocampal synaptic density observed in previous studies. These findings corroborate the idea that structural changes in astrocytic networks are an integral part of plasticity processes occurring in the brain. In other hand, our results indicate that EE decreased the time the animals spent exploring familiar and unfamiliar objects and total time spent exploring both objects, without affecting the capacity of discrimination of objects. These findings indicate a more propitious behavior for species survival in animals subjected to EE, including rapid exploration and learning about the environment.

Abstract:
This chapter present the techniques and interventions of Goal Focused Positive Psychotherapy (GFPP). Highlighted are the therapist’s intentions to emphasize the client’s strengths and to facilitate the expression of positive emotions, hope, and goals while focusing on the therapeutic alliance. Psychotherapy is not viewed as a set of potent scripted treatments that act upon the client. The therapeutic techniques include nonverbal communication, mirroring, open and closed questions, paraphrase and reflection, challenge, summarizing, empathy, interpretation, self-disclosure, immediacy, information giving, and direct guidance. The interventions include capitalization, self-affirmation, formula-first-session-task, reframing, success-finding, encouragement, visualizing success, miracle question, scaling questions, best-possible-self, count your blessings, self-compassion, and mindfulness. The practitioner is urged to use GFPP’s theoretical model to guide the treatment intentions and use any techniques and interventions that fit with the client and the GFPP model.

Abstract:
The application of lightweight materials for tanks for transportation appears promising. Besides saving weight and therefore transportation costs, new complex geometries that depart from common cylindrical shapes of steel tanks can be manufactured. For transportation of dangerous goods, fire and explosion safety must be maintained to prevent accidents with serious consequences. In this work the fire behavior of lightweight tanks made from glass fiber reinforced plastics (GFRP) with complex geometries is investigated. Pretests on intermediate scale GFRP plates are conducted to identify suitable fire protection systems and surface treatments for composite tanks. The fire resistance is shown to be improved by addition of fire protective coatings and integrated layers. Finally, a complex rectangular GFRP tank with a holding capacity of 1100 liters is fire protected with an intumescent fire coating. The tank is filled up to 80 % with water and burned under an engulfing fully developed fire. It was shown that the intumescent layer could expand before the decomposition of the resin occurred. Furthermore, the adhesion between tank surface and coating was maintained. The structure could withstand a fire for more than 20 min.

Abstract:
This paper describes recent experimental development of high speed photography (HSP) applied to UNDer water Explosive (UNDEX) trials. The imaging technique adopted used overhead mirrors and a Perspex® plate on the surface of the water in a tank holding 11,000 litres of water. The HSP has identified the shock wave velocity, shape and timescales and the bubble dynamics as well as the interaction with the target (i.e. Glass reinforced panel (GFRP) composite panel). Charge sizes ranged from 40-140g of PE4 explosive and good images were obtained of the target response. Improvements to the technique will be higher fidelity to enable Digital Image Correlation (DIC) measurements for the panel as well as improved target fixings to prevent lateral motion so that damage could be induced in the panel. The technique can also be used on bigger scale UNDEX trials.

Abstract:
Abstract Drilling is most commonly used secondary machining process for structural joining of Glass Fiber Reinforced Plastic (GFRP) composites. Performing drilling operations on GFRPs/Multi-Walled CarbonNanoTubes (MWCNTs) reinforced GFRPs is really a challenging task due to their non-homogeneity and anisotropic behavior, which directs to generation of material damages. The prime focus of current work is to identify the suitable process parameters for enhancing the performance of drilling of GFRP nanocomposites. In this study, the drilling experiments are conducted on 0.3wt.% MWCNT-GFRP nanocomposites with solid carbide, TiCN and TiAlN coated drills (6mm diameter) under dry and chilled air cutting environments. The dry drilling experiments are conducted without any assistance of cooling fluid in ambient condition. The chilled air at a temperature of 3°C was supplied from the vortex tube. Experimental data is used for ANOVA (balanced) analysis. The cutting parameters such as feed rate, cutting speed and tool type (coating) are considered as input and the measured thrust force, delamination factor and AE RMS signal are treated as output responses. From ANOVA results, it is observed that the influence of feed rate is more on thrust force as compared to cutting speed. The coefficients of determination (R2) shows good fit between thrust force and cutting parameters and the corresponding confidence levels are above 98% for all cutting environments. Similarly, R2 values of delamination factor and AE RMS signals are above 90% and 96% respectively. The minimum thrust force and torque values are noted as 12.61 N and 0.152 N-m respectively at lower feed rate (10 mm/min) and higher cutting speed (1500 RPM) using TiCN coated drill under chilled air cutting environment. The delamination factor is also low (1.025) under the same cutting conditions of minimum cutting forces. A good correlation exists between the thrust force vs. delamination factor (> 0.85) and the delamination factor vs. AE RMS signal (> 0.80) for the selected cutting environments. The recommended range of RMS voltage is 0.083 to 0.121 volts for producing the delamination free holes on GFRP nanocomposites.

<p>Glass fiber-reinforced polymer (GFRP) bars are a viable corrosion-resistant reinforcement for concrete bridge structures.

To respond to this demand, a task force of researchers and practitioners has developed a draft for the second edition of the AASHTO LRFD Bridge Design Specifications for GFRP-RC (AASHTO GFRP-2).

The goals included making the provisions more rational, offsetting some over- conservativeness, and harmonizing the design philosophy with that of authoritative national and international guides and standards.</p><p>This paper illustrates the salient contents of the document, with a focus on flexural design. The GFRP-RC deck of the Anthony Wayne Trail Bridge over Norfolk Southern Railroad (OH) is presented as an example of a common application for GFRP bars in cold-weathered regions. The design with GFRP bars according to AASHTO GFRP-2 is compared to an equivalent design performed according to the first edition of the specifications. Furthermore, the design is compared to traditional and non- corrosive steel-RC alternatives. Economic considerations are included.</p>

In order to improve the reliability and confidence of composite solutions for piping and tanks in the several industrial applications they serve, deeper knowledge on the long-term behavior is needed. In this work a practical predictive approach for the long-term properties of these structures was established. It is based on experimental data previously obtained in comprehensive experimental programs for different types of GFRP pipes, thus covering a wide range of laminate constructions and manufacturing processes. In this paper, the principles, applicability and validation of the design criterion developed are presented and discussed.

Abstract:
Advanced composite materials are defined by hierarchical, heterogeneous, and anisotropic behavior, resulting in complex, multi-scale progressive damage mechanisms, making failure predictions even under simple loading a challenging task. With the widespread usage of polymer composites for structural applications, holes, notches, and other geometric features are often needed for assembly and other functional requirements necessitating improvements to the local architecture around the holes to alleviate associated stress concentration effects. Multiwalled carbon nanotubes (MW-CNTs) when incorporated with epoxy matrix have shown to increase the open-hole tensile (OHT) strength of unidirectional glass fiber reinforced plastic (UD-GFRP) laminates by altering the inherent damage mechanisms. To assess the incipience of damage in MW-CNT modified UD-GFRP laminates, X-ray microcomputed tomography (CT) of the specimen before and after failure have been carried out in the current work. Future work is ongoing to perform in situ tensile testing assisted with X-ray micro-CT to have a better understanding of damage evolution in the specimens.

Abstract:
The increase in stiffness to weight ratio and relative ease of manufacturing fibre reinforced composite pressure vessels, have put such vessels at the forefront of technology. However only limited research and specific codes pertaining exclusively to composite pressure vessel design can be found in literature. The ASME Boiler and Pressure Vessel (BPVC) Section X Code and the European design codes EN 13121-3:2016 (GRP tanks and vessels for use above ground) together with EN 13923:2005 (Filament wound FRP pressure vessels — materials, design, manufacturing and testing) are some of the few known design codes applicable to composite pressure vessels. These codes utilise both design by rule (DBR) and design by analysis (DBA) methods. The authors believe that more studies along the DBA route would benefit the composite pressure vessel design community and make it more accessible to designers and engineers. A similar scenario has already been seen in the last 10 to 15 years for steel pressure vessel design codes when DBA based on inelastic analysis was introduced. In line with these thoughts, this study compares the different design methods to prevent buckling and applies finite element analysis (FEA) to analyse a hemispherical GFRP pressure vessel head subjected to external pressure. The effect of material damage and geometrical imperfections on the final collapse failure is examined and discussed.

Abstract:
Background: Recent evidences have pointed to astrocytes as important players in the Alzheimer’s Disease (AD) pathogenesis. Objective: With this in mind, we aim to longitudinally investigate astrocyte changes in a new important AD transgenic model, the TgF344-AD rat, the first animal model harboring human APP/PS1 mutations which presents age-dependent amyloid and tau pathology. Methods: TgF344-AD rats and wild type littermates were evaluated in three time points: 3, 6 and 9 months of age. Rats underwent a [18F]FDG-microPET, a spatial-memory, an astrocytes CSF biomarkers (ELISA multiplex) and a glutamate uptake (ex-vivo slices) analysis. Examination of further time-points are being conducted at the moment. Results: At 9 months of age, TgF344-AD animals presented an increase in the cortical [18F]FDG uptake and a decline in their alternance performance in the Y-maze task. In the CSF analysis, GFAP was elevated at both 6 months and 9 months, while S100B presented a decrease at 6mo. Additionally, the cortical glutamate uptake was increased at 9 months. Conclusion: This study is the first to longitudinally investigate the in vivo brain glucose metabolism in the TgF344-AD rat model. Our results suggest that this model presents an early increase on glucose metabolism which may be related to astrocytes activation and the increase of glutamate uptake by these cells. Furthermore, we also identified a spatial memory impairment at the same age.

Abstract:
Currently, there are six Generation IV reactor systems under development worldwide: 1) Very-High-Temperature Reactor (VHTR); 2) Sodium-cooled Fast Reactor (SFR); 3) SuperCritical Water-cooled Reactor (SCWR), 4) Gas-cooled Fast Reactor (GFR), 5) Lead-cooled Fast Reactor (LFR); and 6) Molten Salt Reactor (MSR). Of these six systems, Canada has decided to pursue the SCWR as its choice for a Generation IV reactor, with some research being conducted on the VHTR. One main objective of SCWRs is to increase the thermal efficiency of current nuclear power plants from the 30–35% range to approximately 45–50%. In order to accomplish this, SCWRs are being designed to operate well above the critical point of water at pressures of 25 MPa and reactor outlet temperatures up to 625°C. These operating conditions also make the SCWR, along with the VHTR and other Generation IV systems, suitable candidates to support thermochemical hydrogen cogeneration. The design and operation of a facility capable of accurately and safely conducting experiments in supercritical water is a very expensive task. In order to facilitate our understanding of supercritical heat-transfer phenomena, modeling fluids such as carbon dioxide, refrigerants, ammonia and helium can be used to complement our knowledge of supercritical fluids. Some of these fluids, namely helium and carbon dioxide, have also been considered as potential working fluids in some special designs of reactors and power cycles. The objective of this paper is to investigate the feasibility of using alternative working fluids such as helium and Refrigerant-134a (R-134a) by comparing the fluid and transport properties with those of water. Operating conditions of SCWRs are scaled into those of the modeling fluid, R-134a, in order to provide proper SCWR-equivalent conditions. The equivalent properties for helium, which is one possible coolant for the VHTR, are also discussed. The thermophysical properties for selected working fluids are obtained from NIST REFPROP software. The results indicate that the thermophysical properties of the fluids undergo significant changes within the critical and pseudocritical regions similar to that of supercritical water. A sensitivity analysis for the effect of temperature on selected thermophysical properties at various supercritical pressures was performed.
