Abstract:
Purpose China is by far the world’s largest energy consumer and importer. Reasonably forecasting the trend of China’s total energy consumption (CTEC) is of great significance. The purpose of this paper is to propose a new-structure grey system model (NSGM (1, 1)) to forecast CTEC. Design/methodology/approach Two matrices for computing the parameters of NSGM (1, 1) were defined and the specific calculation formula was derived. Since the NSGM (1, 1) model increases the number of its background values, which improves the smoothness effect of the background value and weakens the effects of extreme values in the raw sequence on the model’s performance; hence it has better simulation and prediction performances than traditional grey models. Finally, NSGM (1, 1) was used to forecast China’s total energy consumption during 2016-2025. The forecast showed CTEC will grow rapidly in the next ten years. Findings Therefore, in order to meet the target of keeping CTEC under control at 4.8 billion tons of standard coal in 2020, Chinese government needs to take necessary measures such as transforming the economic development pattern and enhancing the energy utilization efficiency. Originality/value A new-structure grey forecasting model, NSGM (1, 1), is proposed in this paper, which improves the smoothness and weakens the effects of extreme values and has a better structure and performance than those of other grey models. The authors successfully employ the new model to simulate and forecast CTEC. The research findings could aid Chinese government in formulating energy policies and help energy exporters make rational energy yield plans.

Abstract:
Purpose: The purpose of the present study was first to apply the progressive optimization algorithm based automatic volumetric modulated arc therapy (POA-VMAT) technology to accelerate and improve the radiotherapy of cervicothoracic esophageal cancer (CTEC). We comprehensive analyze the feasibility, normal tissue complication probability (NTCP) and dosimetric results of POA-VMAT, manual based VMAT and step-shoot intensity-modulated radiation therapy (IMRT) plans in the treatment of CTEC. Methods: Sixty patients with CTEC with or without concomitant chemotherapy at our institution between 2017 and 2019 were retrospectively identified. The manual 7field-IMRT (7f-IMRT), Single-arc-VMAT and Double-arc-VMAT (Single-Arc/Double-Arc) plans were generated in all cases. The POA-VMAT was designed using the automatic dual-arc VMAT technology of Pinnacle3 9.10 planning system based on progressive optimization algorithm. Specially, it includes the selection of treatment techniques, the running of automated planning scripts, and the evaluation of the final radiotherapy regimen. Subsequently, quantitative evaluation of plans was performed by means of standard dose–volume histograms, homogeneity index (HI) and conformity index (CI). Results: Target dose conformity of the 7f-IMRT plan was inferior to all plans, whereas the Double-Arc plan was slightly inferior to the POA-VMAT but superior to the Single-Arc and 7f-IMRT plan. The HI for 7f-IMRT, Single-Arc, Double-Arc and POA-VMAT were 0.17 ± 0.08, 0.28 ± 0.06, 0.29 ± 0.06 and 0.28 ± 0.03, respectively. For the NTCP results, there was significant statistical difference among POA-VMAT, IMRT and VMAT plans. The total MU was reduced by 48.3% and 42.1% in Single-Arc and POA-VMAT plans compare to IMRT plans. Conclusions: By comprehensive consideration, POA-VMAT efficiently generate acceptable treatment plans for CTEC without dose escalation to OARs and overall superior to manual planning which is a good option for treating CTEC.

Abstract:
Abstract The atypical chemokine receptor CCX-CKR regulates bioavailability of CCL19, CCL21, and CCL25, homeostatic chemokines that play crucial roles in thymic lymphopoiesis. Deletion of CCX-CKR results in accelerated experimental autoimmunity induced by immunization. Here we show that CCX-CKR deletion also increases incidence of a spontaneous Sjögren's syndrome-like pathology, characterized by lymphocytic infiltrates in salivary glands and liver of CCX-CKR−/− mice, suggestive of a defect in self-tolerance when CCX-CKR is deleted. This prompted detailed examination of the thymus in CCX-CKR−/− mice. Negatively selected mature SP cells were less abundant in CCX-CKR−/− thymi, yet expansion of both DP and immature SP cells was apparent. Deletion of CCX-CKR also profoundly reduced proportions of DN3 thymocyte precursors and caused DN2 cells to accumulate within the medulla. These effects are likely driven by alterations in thymic stroma as CCX-CKR−/− mice have fewer cTECs per thymocyte, and cTECs express the highest level of CCX-CKR in the thymus. A profound decrease in CCL25 within the thymic cortex was observed in CCX-CKR−/− thymi, likely accounting for their defects in thymocyte distribution and frequency. These findings identify a novel role for CCX-CKR in regulating cTEC biology, which promotes optimal thymocyte development and selection important for self-tolerant adaptive immunity.

Abstract:
ABSTRACT PRSS16 is a serine protease expressed exclusively in cortical thymic epithelial cells (cTEC) of the thymus, suggesting that it plays a role in the processing of peptide antigens during the positive selection of T cells. Moreover, the human PRSS16 gene is encoded in a region near the class I major histocompatibility complex (MHC) that has been linked to type 1 diabetes mellitus susceptibility. The mouse orthologue Prss16 is conserved in genetic structure, sequence, and pattern of expression. To study the role of Prss16 in thymic development, we generated a deletion mutant of Prss16 and characterized T-lymphocyte populations and MHC class II expression on cortical thymic epithelial cells. Prss16-deficient mice develop normally, are fertile, and show normal thymic morphology, cellularity, and anatomy. The total numbers and frequencies of thymocytes and splenic T-cell populations did not differ from those of wild-type controls. Surface expression of MHC class II on cTEC was also similar in homozygous mutant and wild-type animals, and invariant chain degradation was not impaired by deletion of Prss16. These findings suggest that Prss16 is not required for quantitatively normal T-cell development.

Abstract:
Inhibins and Activins are members of the TGF-βsuperfamily that regulate the differentiation of several cell types. These ligands were initially identified as hormones that regulate the hypothalamus-pituitary-gonadal axis; however, increasing evidence has demonstrated that they are key regulators in the immune system. We have previously demonstrated that Inhibins are the main Activin ligands expressed in the murine thymus and that they regulate thymocyte differentiation, promoting the DN3-DN4 transition and the selection of SP thymocytes. As Inhibins are mainly produced by thymic stromal cells, which also express Activin receptors and Smad proteins, we hypothesized that Inhibins might play a role in stromal cell differentiation and function. Here, we demonstrate that, in the absence of Inhibins, thymic conventional dendritic cells display reduced levels of MHC Class II (MHCII) and CD86. In addition, the ratio between cTECs and mTECs was affected, indicating that mTEC differentiation was favoured and cTEC diminished in the absence of Inhibins. These changes appeared to impact thymocyte selection leading to a decreased selection of CD4SP thymocytes and increased generation of natural regulatory T cells. These findings demonstrate that Inhibins tune the T cell selection process by regulating both thymocyte and stromal cell differentiation.

Abstract:
6502 Background: Trials have stringent inclusion and exclusion criteria to maintain internal validity. However, study findings are often applied to patients in routine practice who do not meet CTEC. Our aim was to characterize the outcomes and magnitude of treatment benefit in these patients. Methods: Patients diagnosed with stage III colon cancer from 2006 and 2008, referred to 1 of 5 regional cancer centers in British Columbia, and assessed for adjuvant chemotherapy (AC) within 12 weeks of surgery were analyzed. Patients were considered trial-eligible (TE) if aged 18 to 79 years, ECOG 0/1, CEA <10, did not receive prior chemotherapy or radiation, and had adequate blood counts and normal cardiac, liver and kidney function. All other patients were deemed trial-ineligible (TI). Results: A total of 820 patients were identified: median age was 69 years (range 60-76), 423 (52%) were men, 365 (45%) were ECOG 0/1 and 592 (72%) received AC. Among patients treated with AC, 370 (63%) were TE and 222 (37%) were TI. Compared to TI patients, those who were TE were younger (63 vs 70 years, p<0.01) and more likely to receive combination regimens rather than single agent AC (56 vs 33%, p<0.01). Outcomes were significantly different among patients who were TE, TI, and those who did not receive AC (Table). In multivariate analyses that adjusted for known prognostic factors such as age, ECOG and T and N stages, both TI patients and those not treated with AC had worse outcomes than TE patients (HR for colon cancer death 1.32, 95%CI 0.86-2.02 and 2.77, 95%CI 1.92-3.99, respectively, p trend <0.01; HR for all cause death 1.24, 95%CI 0.85-1.80 and 2.95, 95%CI 2.17-4.00, respectively, p trend <0.01). Conclusions: In this population-based cohort, colon cancer patients who did not fit CTEC were frequently treated with AC. Outcomes in this TI group were inferior to those in the TE group, but they were better than the subset that did not receive AC. Broadening CTEC to include a segment of the TI population should be considered as there appears to be benefit in selected individuals. [Table: see text]

Abstract:
β-Glucosidase activity plays an essential role for efficient and complete hydrolysis of lignocellulosic biomass. Direct use of fungal fermentation broths can be cost saving relative to using commercial enzymes for production of biofuels and bioproducts. Through a fungal screening program for β-glucosidase activity, strain AP (CBS 127449, Aspergillus saccharolyticus ) showed 10 times greater β-glucosidase activity than the average of all other fungi screened, with Aspergillus niger showing second greatest activity. The potential of a fermentation broth of strain AP was compared with the commercial β-glucosidase-containing enzyme preparations Novozym 188 and Cellic CTec. The fermentation broth was found to be a valid substitute for Novozym 188 in cellobiose hydrolysis. The Michaelis–Menten kinetics affinity constant as well as performance in cellobiose hydrolysis with regard to product inhibition were found to be the same for Novozym 188 and the broth of strain AP. Compared with Novozym 188, the fermentation broth had higher specific activity (11.3 U/mg total protein compared with 7.5 U/mg total protein) and also increased thermostability, identified by the thermal activity number of 66.8 vs. 63.4 °C for Novozym 188. The significant thermostability of strain AP β-glucosidases was further confirmed when compared with Cellic CTec. The β-glucosidases of strain AP were able to degrade cellodextrins with an exo-acting approach and could hydrolyse pretreated bagasse to monomeric sugars when combined with Celluclast 1.5L. The fungus therefore showed great potential as an onsite producer for β-glucosidase activity.

Abstract:
Both tourism destination marketing and the characteristics of holiday travellers have recently undergone radical changes driven by the rapid progress of computer technology. In particular, the advent of the Internet has had a great impact on holiday travellers as well as on the development of tourism promotion and distribution channel strategies. While holiday travellers benefit from the characteristics of Internet use, for example, unlimited information retrieval, flexible accessibility, and direct interactivity with destination marketing organizations (DMOs), the Internet provides DMOs with the critical factor of an increase in operational costs incurred by running all possible online promotional activities and online distribution channels. This paper attempted to discover which Internet functions are popularly used by existing/potential online travellers or which ones are not by testing the Canberra Tourism & Event Corporation (CTEC) web site. As a result, this research intends to provide CTEC with a way to operate its website cost-effectively, which can also lead to increasing the usage satisfaction of CTEC web visitors. Online travellers visiting the CTEC website were surveyed through non-probability self-selected web survey by using segmentation procedure; two key online travel groups: direct and indirect online access groups. Based on the research methodology, this study has discovered several findings. Firstly, CTEC web visitors preferred to use the CTEC website for the purpose of gathering travel information rather than that of online booking or reservations for travel products on the CTEC website. Secondly, comprehensive travel information tailor-made to online individuals was found to be desirable through interactive online activities, while the multimedia, booking, and comparability function were not significant in helping the CTEC online visitors choose the travel destination. Based on their preferences for particular Internet functions, it is evident that web visitors wish to have comprehensive and tailormade online travel information and interaction with the CTEC. Finally, it was revealed that the demographics of the CTEC web visitors were very similar to Internet users identified by previous researchers. Therefore, this study provides insights into website development strategies.

ABSTRACT The aim of this research was to develop and to characterize fermented dairy beverage formulated with Camellia sinensis. Infusion was elaborated with the addiction of dehydrated leaves of C. sinensis in whey (1g.100g-1) which added in sweetened milk (10% sucrose w/w) coagulated by Streptococcus salivarius subsp. thermophilus and Lactobacillus delbrueckii subsp. bulgaricus in proportions of 10, 20, 30 and 40% (v/ w). The control treatment consisted of yogurt added with sucrose (10% w / w). Analysis were performed to quantify dry mass, moisture, ash, protein, fat, sodium, acidity, total quantification of lactic acid bacteria, total antioxidant activity and viscosity at the initial time of production and at 15 and 30 days of storage. Chromatographic determination of volatile compounds and sensory tests of acceptance and consumption intention were conducted at the initial time of production. Dry matter content, moisture, ash and total count of lactic acid bacteria from fermented milk drink formulations were not significantly affected by the amount of infusion of C. sinensis. However, the content of protein, fat and sodium were significantly lower with the increase of the proportion of infusion incorporated into the product. Significant reduction in apparent viscosity occurs with the increase in the amount of infusion added. The total antioxidant activity of the formulations was significantly higher as higher were the amount of added infusion. The addition of infusion contributed to the diversification of volatile aroma and taste makers in the product. The formulation of fermented dairy drink with addition of 30% Infusion C. sinensis was better evaluated in sensory tests, with greater acceptance and greater consumer intent of consumption.

Abstract:
C-terminal Tensin-like (Cten) is a member of the Tensin gene family but lacks the N-terminus actin-binding domain. Cten functions as a tumour suppressor in some cancers while in other cancer types it is recognized to have oncogenic activities. Our group has previously shown that, in colorectal cancer (CRC), Cten is up-regulated and acts as an oncogene which alters several cellular functions including cell migration and invasion. In this project we tried to understand (a) the mechanism through which Cten affects cell function and (b) the mechanisms by which Cten expression may be controlled in cancer. Three cancer models system (colorectal, pancreatic and lung cancer) have been tested to validate our observations. (a) Since Cten is found in complex with integrins at focal adhesions, we hypothesized that it may influence other molecules which are associated with focal adhesion and integrin function. Through a combined approach of forced expression and knockdown experiments, we examined the effect of Cten on ILK and FAK. We found that Cten positively regulates expression of both ILK and FAK and this may be the mechanism through which cell motility is controlled. (b) (i) Activation of the Epidermal Growth Factor Receptor (EGFR) signalling pathway in breast cancer results in up-regulation of Cten accompanied by down-regulation of Tensin 3 (known as the "Tensin switch"). We tested this in CRC and found that stimulation and inhibition of the EGFR using recombinant EGF and the EGFR inhibitor PD135053, resulted in changes in Cten expression (with a tensin switch) and changes in cell motility. Since EGFR classically signals through Kras/Braf we hypothesized that Kras (which is frequently mutated in CRC) may regulate Cten expression. Analysis of CRC cell lines showed an association between Kras/Braf mutation and high Cten expression. Knockdown of Kras in cell lines harbouring Kras mutations resulted in loss of Cten expression while no effect was observed in the cell lines with Braf ,mutations. However Braf knockdown in cell lines with Braf mutation resulted in down-regulation of Cten levels. (ii) CD24 has been shown to be associated with integrins suggesting a possible involvement with Cten at Focal Adhesions. Manipulation of CD24 protein levels in CRC cell lines was mirrored by changes in Cten expression although this effect was not accompanied by a tensin switch. (iii) STAT3 can function as both a tumour suppressor and an oncogene. Modulation of STAT3 levels - either directly through gene knockdown or indirectly through IL-6 stimulation - showed that STAT3 is a negative regulator of Cten. Since around 90% of pancreatic cancers and 60% of lung cancers have Kras mutations we repeated the experiments in these two models. Our data showed that functional activity and regulation of Cten was similar to that seen in CRCs. We can conclude that Cten can regulate cell motility through modulation of FAK and ILK. In addition, Cten is regulated by EGFRKras- Braf signalling and that CD24 and STAT3 are also, respectively, positive and negative regulators of Cten. Finally, Cten activity is broadly consistent in three different cancer models. Future studies should involve further refinement of the signalling pathway and study of other tumour types involving frequent Kras mutations. ..

Abstract:
Cten (also known as Tensin4) is the fourth member of the Tensin gene family. It lacks the N terminal actin binding domain while retaining the C terminal SH2 and PTB domains. This helps to bind Cten to the intracytoplasmic tail of β1 integrin and puts it at the heart of focal adhesions. It is reported to be a tumour suppressor in kidney and prostate cancer where normal tissues show high expression. However in a number of tumours, including colorectal cancer, Cten has been labelled as an oncogene. Cten which normally is a cytoplasmic protein gives nuclear staining in colorectal metastatic deposits. It increases motility, invasion and colony formation in colorectal cancer cells. In this study we have tried toexplore the mechanism of functional activity and regulation of Cten. We looked at Cten in the nucleus in vitro and identified new downstream binding targets. In addition we investigated the role of the SH2 domain of Cten concentrating on its downstream signalling molecules and binding partners. Furthermore, we explored regulators of Cten. In this study we have forced nuclear localisation of Cten by tagging it with a nuclear localisation sequence (NLS) and found a significant increase in cell motility. In order to investigate the SH2 domain we used site directed mutagenesis to change potentially important amino acids namely Arginine at 474 to Alanine (R474A), which is important for binding tyrosine phosphorylated proteins. Moreover, we displayed that Cten underwent tyrosine phosphorylation and additionally changed three tyrosine residues i.e. Y449F, Y479F and Y530F via site directed mutagenesis. We found R474 and Y479 to be important in regulating cell motility and that known downstream targets such as ILK and FAK are dependent on an intact SH2 domain. Furthermore we have identified Cten to be physically bound to FAK in the cytoplasm and nucleus and new downstream targets identified such as Src and Paxillin. Regarding possible regulators of Cten, we found that Cten might be a possible substrate for calpain. Another regulator considered was CD24 due to its role in movement of integrins into lipid rafts and we found it was a positive regulator of Cten. In conclusion localisation of Cten into the nucleus causes an augmentation of its motility enhancing functions. Cten regulates cell motility via its SH2 domain. Arginine 474 and Tyrosine 479 are important for its function. Cten regulates levels of ILK, FAK, Src and Paxillin through its SH2 domain and binds to FAK in both cytoplasm and nucleus. Calpain and CD24 were found to possible regulators of Cten in colorectal cancer. Future studies are needed to define its role in signalling at focal adhesions and these studies should be validated in other cancer cell models as well to establish Cten as regulator of cell motility in cancer.

Abstract:
Learning in school requires active engagement. Student engagement is an important aspect for all students, whether urban, suburban, or rural, and regardless of socioeconomic background. Students enter Career and Technical Education (CTE) programs for a multitude of reasons and CTE programs offer unique support for student success by increasing student engagement. This study will focus on CTE teachers' perceptions of the influence that CTE programs and industry credentialing have on student engagement. Utilizing information on student engagement will help educators develop strategies to promote student motivation and student engagement, thus leading to student academic success. This study is a quantitative, descriptive statistical study in which the researcher examined studies that focused on student engagement and student engagement predictors. The research identified six qualities of student engagement: positive conduct and absence of disruptive conduct, school attendance, academic progress, social membership, high expectations in students' ability to achieve, and emotional support. The researcher developed a survey to examine teachers' perceptions of CTE influence on student engagement by including the six qualities of student engagement as guidelines for questionnaire development. Results of the survey indicate that CTE teachers identify all six domains of student engagement as represented within their course structure. Responses of all groups were similar, while their levels of industry involvement different. Additional results of all teacher responses are provided in the paper.

Abstract:
C-terminal tensin-like (Cten, also known as Tensin4) is the member of the tensin gene family. Cten functions as an oncogene in a variety of cancer types and its expression is commonly associated with poor prognosis and metastasis in colorectal cancer (CRC). Although several studies have shown that Cten has a critical role in the regulation of cell motility and invasion in different tumour tissues, the underlying signalling mechanisms have not been fully elucidated. This thesis investigated the biological activity of Cten in four different ways in order to further elucidate the mechanisms of Cten signalling in CRC cells. Potential downstream targets of Cten signalling involved in the regulation of epithelial-to-mesenchymal transition (EMT) induced cell motility i.e. Rho-associated protein kinase1 (ROCK1), Src and Snail were investigated. Cten expression was manipulated in different cell lines using multiple approaches including forced expression, gene knockdown and constitutive depletion (through Crispr/Cas9 gene deletion) to eliminate artefacts of methodology and cell line specific effects. Snail, Src and ROCK1 were identified as novel downstream targets of Cten signalling and additionally, Cten was shown to increase the stabilisation of both Src and Snail proteins. The functional relevance of Cten-Snail, Cten-Src and Cten-ROCK1 signalling was assessed, and the overall findings demonstrated that Cten could promote cell motility and colony formation directly through the positive regulation of the Src/ROCK1/Snail dependent axis. To gain a deeper insight into the mechanisms of Cten’s biological function, mutations, at two important residues (i.e. arginine 474 and tyrosine 479) in the Src homology 2 (SH2) domain of Cten were introduced into one construct (GFP-CtenR474A+Y479F) using site directed mutagenesis. These two residues in the SH2 domain of Cten were found to not only be important for interacting with Src, ROCK1, or Snail signalling, but also for regulating cell motility and colony formation efficiency. Numerous Cten regulatory factors have been identified, however, little is known about how Cten is activated and regulated in cancer cells. The relationship between transforming growth factor beta 1 (TGFβ1) and Cten was investigated and stimulation of cells with TGFβ1 or knockdown of TGFβ1 resulted in changes in Cten expression as well as its downstream targets of ROCK1, Src, Snail, and N-cadherin. Furthermore, this positive interaction between TGFβ1 and Cten was functionally relevant and caused changes in cell motility. and the nuclear translocation of ROCK1, Src, and Snail protein increased by TGFβ1 is probably mediated via upregulation of the Cten signalling pathway The biological function of Cten in the nucleus was further investigated and shown to increase nuclear localisation of Src, ROCK1, and Snail, further promoting the migratory capability and colony formation efficiency in CRC cells. Finally, Cten expression was shown to positively correlate with both ROCK1 and Src expression in a series of primary CRCs. This correlation was consistent with that observed following manipulation of Cten expression in CRC cell lines. In conclusion, this study has revealed a number of novel findings regarding the biological function of Cten signalling in CRC. However, further validation of the findings may enhance the understanding of the role of Cten in the invasion-metastasis cascade in the future.

Nesta dissertação buscou-se avaliar metrologicamente um banco de ensaios dinamométricos específico, utilizado para analisar a eficiência de motores, lubrificantes e combustíveis, por meio de métodos de comparação dos valores medidos com valores padrões. As grandezas mensuradas foram: velocidade de rotação do eixo de um motor, torque neste eixo, temperaturas e pressões no motor e no dinamômetro, elemento que atua como freio do motor para proporcionar uma simulação das condições reais de trabalho. Foi necessário utilizar dois métodos distintos para avaliação de cada uma das grandezas mensuradas. Foram mensuradas velocidades do motor funcionando e velocidades simuladas, tanto inferiores como superiores às velocidades de operação do motor, determinando os limites superior e inferior de resposta do sistema de medição. Para avaliar a medição de torque, foram produzidos torques conhecidos (padrão), correlacionados com torques medidos no motor funcionando. Temperaturas foram produzidas por um banho termostático, mensuradas com equipamentos calibrados e em seguida comparadas com as indicadas pelo sistema de medição, sendo também utilizado um método simulador de informações de temperaturas, chegando a ser simuladas de -200 graus Celsius a 650 graus Celsius. Pressões foram geradas por uma bomba de pressão padrão e lidas pelo sistema de medição, sendo detectado funcionamento inapropriado de 2 canais. Os resultados de cada grandeza foram tratados estatisticamente sendo validadas suas utilizações nos cálculos executados. Confirmadas estatisticamente as validades dos resultados, as incertezas de medição foram calculadas, sendo utilizadas também informações dos certificados de calibração dos equipamentos usados nas medições realizadas. Sugestões foram apresentadas para que melhoria sejam incrementadas ao sistema de medição que demonstrou estar funcionando de forma satisfatória, apresentando, no entanto, algumas oportunidades de melhorias.
This work intended to evaluate, metrologically, a specific bench of dynamometric tests, used to analyze the efficiency of engines, lubricants and fuels, through methods that compare the measured values with standards. The measured quantities were: rotation speed of the engine shaft, torque on this same shaft, temperature and pressure of both engine and dynamometer, element that acts as the engine brake so it can simulate a real work condition. It was necessary to use two different methods to evaluate each measured quantity. It was measured the working engine speed and simulated speeds, both higher and lower than the engine operating speeds, establishing the higher and the lower limits of the measurement system. To evaluate the torque measurement, known torques (standards), were produced, and related to the measured torques in the working engine. Temperatures were produced by a thermal bath, measured with calibrated equipment, and then compared with the temperatures indicated by the measuring system, being also used a simulated method for temperatures information, with a range of simulation between -200 Celsius degrees and 650 Celsius degrees. The pressures were created by a standard pressure pump and read by the measuring system, being detected an inappropriate operation of 2 channels. The results were treated statistically, being validated the utilizations on the executed calculations. Having been statistically confirmed the validity of the results, the measurement uncertainties were calculated, being also used the information from the equipment calibration certificate. Suggestions were presented so that improvemenst can be made to the Measuring System.

Abstract:
A l'occasion de l'écriture de la loi d'orientation agricole de 1999, la référence explicite au territoire entre dans le vocabulaire de la politique publique agricole. La procédure mise en place pour la détermination des contenus des Contrats Territoriaux d'Exploitation, CTE, est expérimentale et largement ascendante. Cette thèse propose une analyse des conceptions et pratiques du territoire qui ont été construites et mobilisées par des acteurs individuels et collectifs à l'occasion de cette procédure. Quel rôle et quelle place joue le territoire aujourd'hui dans les projets de vie et les projets professionnels des agriculteurs et des agents de développement du Tarn et de l'Aude ? Quelle place ont ces groupes sociaux dans les projets territoriaux ? En montrant comment la ré-interprétation du territoire a permis des échanges et la construction de compromis localisés, nous proposons un éclairage sur une procédure qui avait pour objectif de revivifier les liens entre les agriculteurs et la société en usant de(s) territoire(s)
When the French government decided to have a new Agricultural Act voted in 1999, it used the word « territory » as an incentive for farmers and extension workers to find a new way to interact with the whole society. Taking into account that the status of agriculture in the contemporary rural communities was at stake, farmers and extension workers in Aude and Tarn have tried to work on a renewal of the ways and means of the word “territory”. In this work I point out how people dealt with the different means of the word “territory” to build a common ground on which to build new ways to share the rural space, live, work, network in an extended and open community aiming at local and global sustainability

In order to design AP1000 protection system based on the FirmSys platform of CTEC, the AP1000 protection system based on CommonQ platform is analyzed and researched. Through the comparison of the FirmSys platform and the CommonQ platform, it is found that the number of cabinets should be increased largely if the protection system design based on the FirmSys platform refers to Westinghouse AP1000 protection system architecture. So that the cabinets can not be laid out in the electrical room due to the AP1000 electrical room space constraints. In order to solve this problem and to achieve the required reliability, the optimization of the emergency reactor trip and engineered safety features actuation control method based on FirmSys platform is studied. At last a new protection system architecture design is completed. It is proved that the optimized protection system architecture, in which the number of cabinets is reduced and the reliability is improved, not only can solve the cabinet layout problem, but also can meet the design requirements of AP1000.

Abstract:
Abstract In this work, we analyze and design structures and materials that possess custom thermal expansion. These structures and materials are composed of a base unit inspired by the tensegrity “D-bar” (or double-pyramid) topology. We derive, for the first time, analytical equations for the linearized and geometrically exact coefficients of thermal expansion (CTEs) of bi-material D-bar structures with arbitrary shape and complexity. Numerical results obtained using the geometrically exact CTE equations are compared with results obtained using the linearized CTE equations, showing that the latter are accurate only in cases where temperature changes are small. Further results show that D-bar structures of low complexity can produce a wide range of CTEs, including positive, zero, and negative values. These CTE values are exhibited for a range of materials that allows for easy manufacturing (materials with CTE ratios as low as 2). Thus, it is concluded that D-bar structures show promise for applications in aerospace engineering and other fields where new materials of tailorable thermal expansion are needed to decrease the substantial thermal stresses caused by large temperature changes.

Abstract The SEMATECH/SEMI roadmap forecasts increased density requirements for printed circuit board manufacturing to accommodate smaller form factor interconnects, increased pin counts, and routing densities on a range of PCB sizes and thicknesses. As a result, the effect of materials. thermal expansion properties may further impact the structural or physical integrity and subsequent electrical properties for high speed and thermal management requirements. This study demonstrated that various sample coupons selected from PCB boards with different amounts of copper showed a corresponding coefficient of thermal expansion (CTE) correlation in the Z-axis (CTEZ) and can be modeled using a constitutive equation. Moreover, samples were further evaluated from the effect of increasing temperature and showed that the CTE indeed affects copper-interconnect physical structures such as copper vias and barrels in terms of elongation or strain.

Abstract:
This paper mainly concentrates on the design and analysis of the annulus with zero thermal expansion coefficient (ZTE) aiming to solve the heat generation and deformation in high speed bearing. First, a fork-like lattice cell inspired by the basic triangular cell is put forward and further applied to construct an annulus. The stretch-dominated lattice cell utilizes the Poisson’s contraction effect to achieve the tailorable thermal expansion coefficient (CTE). The thermal behaviors differences between the continuous interfaces and lattice cells will lead to the internal stress. Thus, the CTE of the annulus consisting of the lattice cell can be tailored to zero even negative values through the offset between the thermal-strain and force-strain. Then a theoretical model is established with some appropriate assumptions to reveal the quantitative relations among the geometrical parameters, material properties and equivalent CTEs thoroughly. The prerequisites for realizing a zero CTE are further derived in terms of material limitations and geometric constraints. Finally, FEA method is implemented to verify and analyze the thermal behaviors of annulus. The proposed annulus design characterized by the CTE tunability, structure efficiency and continuous interfaces is hopefully to be applied in the high speed bearings, adapters between the shaft and collar and fastener screws.

Abstract:
Coefficient of thermal expansion (CTE) characteristic of organic materials for substrates in flip chip package application demanded by semiconductor package requirements is becoming lower than ever. In general, height restrictions are imposed on package-on-package (PoP) devices in mobile applications. One should hence establish a tight budget on the height variation in manufacturing of the devices. Given such background, a lowering of the CTE characteristic of package substrates is an attractive solution for reducing package deformation upon manufacturing, since it contributes to minimize CTE mismatch of the substrates with silicon chips. In large-die flip chip applications such as high-end processors, a lower CTE substrate can mitigate mechanical stress not only on low-k layers in back end of the line (BEOL) underneath the chip bumps, but also on underfill layers during thermal cycling. Therefore an introduction of lower CTE materials in organic substrates is becoming essential for future applications of electronic devices. In this paper, thermal deformation behaviors of organic substrates associated with lowering of the CTEs of their constituent materials are analyzed by finite element analysis (FEA). The analyses are done on a 3-2-3 build-up layer structure substrate in order to focus onto typical application specific integrated circuit (ASIC) products. A finite element model for a test substrate is constructed by a method in which the substrate is divided into sections according to its circuitry patterns so that the lateral inhomogeneity of mechanical property is taken into account. The finite element analyses using the model showed that the package warpage decreases with lowering of the effective CTE of the substrate, but the warpage of the substrate itself increases and its surface profile changes from a concave shape to a convex shape. The analysis result of substrate warpage variation with the build-up material’s CTE showed that the selection of build-up materials with appropriate material properties can contribute to reduce the substrate warpage. The analysis also showed that the adverse impact to the substrate’s CTE reduction by such material selection is limited.

Abstract Tensegrity lattices are networks of axially loaded members designed to efficiently use material and exhibit properties such as minimum mass load-carrying or energy absorption capabilities. This work entails the modeling and design of tensegrity “D-bar” lattices with specified orthotropic compressive strength. The objectives for the design of the lattices include minimum mass density and minimum error between the orthotropic coefficients of thermal expansion (CTEs) of the lattice and given target values. The studied D-bar structures are formed by joining two equal pyramids base-to-base where tensile strings form the edges of the pyramid bases and compressive bars form the remaining edges. Orthorhombic lattices having D-bars as their edges are designed to support compressive forces and exhibit positive, zero, or negative CTE values along their three principal directions. It is investigated how the geometry of the individual D-bar components may be adjusted, for the given compressive strength, to prevent local yielding and buckling failure with the minimum required material. Analytical formulas for the minimum density and the CTE of the D-bar lattices are provided, and a numerical framework for the integration of these formulas along with size and topological constraints is developed. Design trade-offs between minimum lattice density and minimum error from the target CTE, which are found to be competing structural performance metrics, are visualized and investigated.
