    This research is motivated by the poor condition of the area at the Jungke Traditional Market, especially in the physical condition of the building that is poorly maintained, irregular spatial arrangement, supporting facilities that are less comfortable for users, lack of security systems in buildings and the absence of local cultural aspects that reflect the people's market. So the purpose of this study is (1) Planning a building design that can accommodate the commodities of traders and local cultural communities for the economic sustainability of the surrounding community and preserving local wisdom, (2) Planning the design of Jungke Traditional Market that pays attention to the smooth circulation of people and goods, (3) Provide facilities that are feasible and comfortable to use for all people. To overcome the problems that exist in the Jungke Traditional Market, a design design was made to revitalize the Jungke Traditional Market by carrying out the concept of a Neo Vernacular Architecture approach, because the design of this market wants to show the locality of local culture with facilities that will later shape cultural values as market identity itself, market design with an urban context with sustainable infrastructure that can later keep up with the times.

    Soil stabilization with cement is commonly used to improve the strength and hardness of natural soil formation by adding reinforcing aids such as cement, lime, gypsum and fly ash. It has many applications, such as foundation engineering, providing retaining walls for excavation, liquefaction mitigation, hydraulic retaining walls and environmental remediation. This paper presents a brief history and evaluation of soil stabilization using cement as an effective chemical stabilizer to improve the strength and durability requirements of sandy and sandy soils. lighting. In addition, several previous works regarding the strength of soils after mixing with cement in different ratios are considered, including analytical analysis, laboratory work and current tests. large school. This study will refer to 6 previous studies on cement stability on different soil conditions: sandy soil and clay soil. The study will analyze the results of unreinforced compressive strength for sandy and clayey soils at the hardening time of 28 days. The results indicate that cement as a stabilizer is effective in improving both soft and sandy clay soils, and based on the results of the unreinforced compression test, it is more effective on sandy soils than on clay soils

    Reactor Anti-Neutrino Oscillations and Gadolinium Loaded Super-Kamiokande Detector

    Get PDF
    We explore the potential of measuring the solar neutrino oscillation parameters in the proposed gadolinium loaded Super-Kamiokande (SK-Gd) detector. Gadolinium dissolved in water can detect neutrons much more efficiently than pure water. This imparts the detector the ability to observe electron type antineutrinos, transforming Super-Kamiokande into a huge reactor antineutrino detector with an event rate approximately 43 times higher than that observed in KamLAND. We simulate the reactor antineutrino data expected in this high statistics detector. We use these prospective data to study the precision with which the solar neutrino oscillation parameters, Δm2\Delta m^2_{\odot} and sin2θ\sin^2\theta_{\odot}, can be determined i) with the SK-Gd detector, and ii) by combining the SK-Gd data with the global data on solar neutrino oscillations. For comparison and completeness the allowed regions of Δm2\Delta m^2_{\odot} and sin2θ\sin^2\theta_{\odot}, expected to be obtained from the data of the solar neutrino and KamLAND experiments, are also presented.Comment: Includes Addendum with a brief discussion of the implications of the 766.3 kTy KamLAND spectrum data on the sensitivity of the SK-Gd experiment; two new figures added in the Addendum; typos in Table 1 correcte

    On Deviations from Bimaximal Neutrino Mixing

    Get PDF
    The PMNS neutrino mixing matrix U_{PMNS} is in general a product of two unitary matrices U_{lep} and U_{\nu} arising from the diagonalization of the charged lepton and neutrino mass matrices, U_{PMNS} = U^{\dagger}_{lep} U_{\nu}. Assuming that U_{\nu} is a bimaximal mixing matrix, we investigate the possible forms of U_{lep}. We identify three possible generic structures of U_{lep}, which are compatible with the existing data on neutrino mixing. One corresponds to a hierarchical ``CKM-like'' matrix. In this case relatively large values of the solar neutrino mixing angle \theta_{sol}, and of |U_{e3}|^2, are typically predicted, \tan^2\theta_{sol} \gtap 0.42, |U_{e3}|^2 \gtap 0.02, while the atmospheric neutrino mixing angle \theta_{atm} can deviate noticeably from \pi/4, \sin^2 2\theta_{atm} \gtap 0.95. The second corresponds to one of the mixing angles in U_{lep} being equal to \pi/2, and predicts practically maximal atmospheric neutrino mixing \sin^2 2\theta_{atm} \simeq 1. Large atmospheric neutrino mixing, \sin^2 2\theta_{atm} \gtap 0.95, is naturally predicted by the third possible generic structure of U_{lep}, which corresponds to all three mixing angles in U_{lep} being large. We focus especially on the case of CP-nonconservation, analyzing it in detail. We show how the CP-violating phases, arising from the diagonalization of the neutrino and charged lepton mass matrices, contribute to the measured neutrino mixing observables.Comment: 26 pages, 6 figures.

    A new reactor power plant Shika-2, with a power of approximately 4 GW and at a distance of about 88 km from the KamLAND detector is scheduled to start operating in March 2006. We study the impact of the νˉe\bar\nu_e flux from this reactor on the sensitivity of the KamLAND experiment to the solar neutrino oscillation parameters. We present results on prospective determination of Δm2\Delta m^2_\odot and sin2θ\sin^2\theta_\odot using the combined data from KamLAND and the solar neutrino experiments, including the effect of the Shika-2 contribution to the KamLAND signal and the latest data from the salt enriched phase of the SNO experiment. We find that contrary to the expectations, the addition of the Shika-2 reactor flux does not improve the sin2θ\sin^2\theta_\odot sensitivity of KamLAND, while the ambiguity in Δm2\Delta m^2_\odot measurement may even increase, as a result of the averaging effect between Kashiwazaki and the Shika-2 reactor contributions to the KamLAND signal.Comment: Version to appear in Phys. Lett.

    Update of the solar neutrino oscillation analysis with the 766 Ty KamLAND spectrum

    We investigate the impact of the 766.3 Ty KamLAND spectrum data on the determination of the solar neutrino oscillation parameters. We show that the observed spectrum distortion in the KamLAND experiment firmly establishes Δm212\Delta m^2_{21} to lie in the low-LMA solution region. The high-LMA solution is excluded at more than 4σ\sigma by the global solar neutrino and KamLAND spectrum data. The maximal solar neutrino mixing is ruled out at 6σ6\sigma level. The 3σ3\sigma allowed region in the Δm212sin2θ12\Delta m^2_{21}-\sin^2\theta_{12} plane is found to be remarkably stable with respect to leaving out the data from one of the solar neutrino experiments from the global analysis. We perform a three flavor neutrino oscillation analysis of the global solar neutrino and KamLAND spectrum data as well. The 3σ3\sigma upper limit on sin2θ13\sin^2\theta_{13} is found to be sin2θ13<0.055 \sin^2\theta_{13} <0.055. We derive predictions for the CC to NC event rate ratio and day-night (D-N) asymmetry in the CC event rate, measured in the SNO experiment, and for the suppression of the event rate in the BOREXINO and LowNu experiments. Prospective high precision measurements of the solar neutrino oscillation parameters are also discussed.Comment: Additional backgrounds recently identified by the KamLAND collaboration included in the analysis. Fit of KamLAND data to neutrino oscillation seen to improve. Slight change in the best-fit value of Δm2\Delta m^2 obtaine

    The combined action of the intracellular regions regulates FGFR2 kinase activity

    Get PDF
    Receptor tyrosine kinases (RTKs) are typically activated through a precise sequence of intracellular phosphorylation events starting with a tyrosine residue on the activation loop (A-loop) of the kinase domain (KD). From this point the mono-phosphorylated enzyme is active, but subject to stringent regulatory mechanisms which can vary dramatically across the different RTKs. In the absence of extracellular stimulation, fibroblast growth factor receptor 2 (FGFR2) exists in the mono-phosphorylated state in which catalytic activity is regulated to allow rapid response upon ligand binding, whilst restricting ligand-independent activation. Failure of this regulation is responsible for pathologic outcomes including cancer. Here we reveal the molecular mechanistic detail of KD control based on combinatorial interactions of the juxtamembrane (JM) and the C-terminal tail (CT) regions of the receptor. JM stabilizes the asymmetric dimeric KD required for substrate phosphorylation, whilst CT binding opposes dimerization, and down-regulates activity. Direct binding between JM and CT delays the recruitment of downstream effector proteins adding a further control step as the receptor proceeds to full activation. Our findings underscore the diversity in mechanisms of RTK oligomerisation and activation
