    Culture heritage provides us an automatic sense of unity and belonging, which allows us to better understand previous generation and history of where we come from. The preservation of heritage is closely linked to the culture of society where culture plays a vital role in urban, economic and social development. The research aim is to overview the main principles of green architecture and identify the main heritage conservation approaches as a theoretical approach to identify the most suitable conservation approach that applies all the principles of the green architecture. The chosen approach will be applied on our case study “Vancouver city in Canada” to verity our conclusion from the theoretical study

    This study was conducted through the seasons of 2013 and 2014 to determine the optimum bud loads/ vine for Autumn Royal seedless "grapevines. Three years old uniform vines were uniform chosen and pruned to four levels of bud load, namely (32, 42, 52 and 60 buds/ vine). With fruiting spur at 2, 3 and 4 buds per spur The results showed that the percentage of bursted buds was decreased significantly by increasing bud load /vine in the two seasons of the study. Data also indicated that 42 buds/ vine were more suitable for Autumn Royal seedlessgrapevines to produce good yield and fruit quality. On the other hand, 32 buds/vine or 60 buds/vine were unfavorable science it produced rather clusters. In addition, pruning Autumn Royal seedless "grapevines to 42buds /vine by leaving 21 spur  with 2 eyes/spur or leaving 14 spur with 3 eyes per spur resulted a high yield and good quality, reduced cluster compactness and reduced shoot berries %,  gave the greatest cluster weight, berry firmness, adherence, T.S.S and anthocyanin content. Increasing bud load increased number of cluster/vine and yield but reduced cluster weight. Vines pruned to 32 buds / vine gave the greatest C/N ratio of the canes. Whereas vines pruned to 60 buds / vine showed higher percent of T.A than the other levels of bud load and cane length

    Compression of Antiproton Clouds for Antihydrogen Trapping

    Full text link
    Control of the radial profile of trapped antiproton clouds is critical to trapping antihydrogen. We report the first detailed measurements of the radial manipulation of antiproton clouds, including areal density compressions by factors as large as ten, by manipulating spatially overlapped electron plasmas. We show detailed measurements of the near-axis antiproton radial profile and its relation to that of the electron plasma

    The influence of using digital diagnostic information on orthodontic treatment planning - a pilot study

    Get PDF
    The purpose of this pilot study was to assess whether orthodontic treatment planning is reproducible when carried out using digital records compared with clinical examinations or using standard records. The study also assessed patients' opinion of face-to-face consultations and potential use of teleorthodontics. The study was designed as a prospective observational cross-sectional pilot study and carried out in a UK dental teaching hospital involving 27 subjects. Four consultant Orthodontists carried out treatment planning, firstly following a clinical examination, then using standard records, and then using digital records. Each subject completed a questionnaire. Cohen's kappa coefficient and Fleiss' kappa coefficient were used to assess intra-observer reproducibility and inter-observer reproducibility of treatment planning decisions, respectively. A change in the diagnostic information format affected treatment planning reproducibility for half of the observers. Inter-observer reproducibility was greater when using hard copy records in comparison to digital records. No subjects were unsatisfied with their face-to-face consultation

    A novel antiproton radial diagnostic based on octupole induced ballistic loss

    Get PDF
    We report results from a novel diagnostic that probes the outer radial profile of trapped antiproton clouds. The diagnostic allows us to determine the profile by monitoring the time-history of antiproton losses that occur as an octupole field in the antiproton confinement region is increased. We show several examples of how this diagnostic helps us to understand the radial dynamics of antiprotons in normal and nested Penning-Malmberg traps. Better understanding of these dynamics may aid current attempts to trap antihydrogen atoms

    Biological measurement beyond the quantum limit

    Full text link
    Quantum noise places a fundamental limit on the per photon sensitivity attainable in optical measurements. This limit is of particular importance in biological measurements, where the optical power must be constrained to avoid damage to the specimen. By using non-classically correlated light, we demonstrated that the quantum limit can be surpassed in biological measurements. Quantum enhanced microrheology was performed within yeast cells by tracking naturally occurring lipid granules with sensitivity 2.4 dB beyond the quantum noise limit. The viscoelastic properties of the cytoplasm could thereby be determined with a 64% improved measurement rate. This demonstration paves the way to apply quantum resources broadly in a biological context

    Effect of Denture Base Reinforcement Using Light Cured E- Glass Fibers on the Level of Salivary Immunoglobulin A

    BACKGROUND: A gap still exists between in vitro and clinical studies concerning the biocompatibility of the material in the oral environment and their potential to cause immunological undesirable side effects. The uses of glass fibres to improve the mechanical properties of acrylic resin denture base polymers are well documented in vitro. AIM: The present study aimed to evaluate the effect of denture base reinforcement using light-cured E- glass fibres mesh on the level of salivary immunoglobulin A (S-IgA) in patients wearing complete dentures. MATERIAL AND METHODS: Fourteen completely edentulous patients, in need of complete dentures, participated in the study. The patients were divided into two groups (n = 7) according to the treatment protocol. In the first group, patients received conventional heat-cured acrylic resin dentures. In the second group, the mandibular dentures were reinforced using light cured resin impregnated E glass fibres mesh. In both groups, salivary samples were collected using passive drool technique. The level IgA was assessed by enzyme-linked immunosorbent assay (ELISA) technique at different time intervals. Statistical analysis was carried out using one-way ANOVA followed by Tukey`s post-hoc test and independent t-test. The significant level was set at P ≤ 0.05. RESULTS: Acrylic resin dentures and reinforced ones demonstrated an increase in the mean values of IgA level at the end of the follow-up intervals. And this increase was statistically significant (P ≤ 0.05). Although, the reinforced dentures revealed higher mean values, there was no statistically significant difference between the two groups (P > 0.05) CONCLUSIONS: Within the limitations of the present study, the following could be concluded: (1) the insertion of complete dentures induced changes in the level of IgA; and (2) denture base reinforcement using light cured resin impregnated E-glass fibres mesh had a similar effect to that of heat cured acrylic resin on the level of IgA
