    The study is about customer satisfaction towards the product quality. The effect of low pricing product with the product quality plays the same result of low price products produces low quality product and vice-versa. Data instrument that is used in obtaining data is by distributing survey questionnaire. The main purpose of this research is to classify whether the eight dimension of product quality after price discounting is satisfying towards customer. The respondent of the research was chosen through sampling method by using the non-probability sampling. The results infer that that the customer’s satisfaction towards the discounted product quality is based on the three attributes most namely perceived quality, performance and reliability. The Perceived quality- on image, brand name, and advertising is positively related to the level of satisfaction towards the quality of discounted product; were all supported as the relationships between the variables were statistically significant. This study does also provide useful guidelines for future researcher to be more rigorous and also in-depth to empirical and theoretical processes. In future study, customer satisfaction towards discounted product quality of the product to be specified to a product only determine by one gender (female) and also a perception towards a certain discounted price level of a product and its quality with extension of product design and customer requirements

    The significance of ΛΛ\Lambda\Lambda-Ξ\XiN coupling in double-Λ\Lambda hypernuclei has been studied. The Pauli suppression effect due to this coupling in ΛΛ6^6_{\Lambda\Lambda}He has been found to be 0.43 MeV for the coupling strength of the NSC97e potential. This indicates that the free-space ΛΛ\Lambda\Lambda interaction is stronger by about 55^{\circ} phase shift than that deduced from the empirical data of ΛΛ6^6_{\Lambda\Lambda}He without including the Pauli suppression effect. In ΛΛ5^5_{\Lambda\Lambda}He and ΛΛ5^5_{\Lambda\Lambda}H, an attractive term arising from ΛΛ\Lambda\Lambda-Ξ\XiN conversion is enhanced by the formation of an alpha particle in intermediate Ξ\Xi states. According to this enhancement, we have found that the ΛΛ\Lambda\Lambda binding energy (ΔBΛΛ\Delta B_{\Lambda\Lambda}) of ΛΛ5^5_{\Lambda\Lambda}He is about 0.27 MeV larger than that of ΛΛ6^6_{\Lambda\Lambda}He for the NSC97e coupling strength. This finding deviates from a general picture that the heavier is the core nucleus, the larger is ΔBΛΛ\Delta B_{\Lambda\Lambda}.Comment: 16 pages with 2 figure

    We describe {\it ab initio} calculations of doubly strange, S=2S=-2, ss-shell hypernuclei (ΛΛ4^4_{\Lambda\Lambda}H, ΛΛ5^5_{\Lambda\Lambda}H, ΛΛ5^5_{\Lambda\Lambda}He and ΛΛ6^6_{\Lambda\Lambda}He) as a first attempt to explore the few-body problem of the {\it full}-coupled channel scheme for these systems. The wave function includes ΛΛ\Lambda\Lambda, ΛΣ\Lambda\Sigma, NΞN\Xi and ΣΣ\Sigma\Sigma channels. Minnesota NNNN, D2^\prime YNYN, and simulated YYYY potentials based on the Nijmegen hard-core model, are used. Bound state solutions of these systems are obtained. We find that a set of phenomenological B8B8B_8B_8 interactions among the octet baryons in S=0,1S=0, -1 and -2 sectors, which is consistent with all of the available experimental binding energies of S=0,1S=0, -1 and -2 ss-shell (hyper-)nuclei, can predict a particle stable bound state of ΛΛ4^4_{\Lambda\Lambda}H. For ΛΛ5^5_{\Lambda\Lambda}H and ΛΛ5^5_{\Lambda\Lambda}He, ΛNΣN\Lambda N-\Sigma N and ΞNΛΣ\Xi N-\Lambda\Sigma potentials enhance the net ΛΛNΞ\Lambda\Lambda-N\Xi coupling, and a large Ξ\Xi probability is obtained even for a weaker ΛΛNΞ\Lambda\Lambda-N\Xi potential.Comment: 4 pages, 1 figur

    Get PDF
    This study aims to examine the co-movement of stock market volatility between China and ASEAN-5 countries from the year 2000 to 2009. This study applies the standard linear GARCH (1, 1) model where these models estimate using monthly price data from year 2000 to 2009 for China, Malaysia, Singapore, Thailand, Indonesia and Philippines. The standard time series econometrics analysis is used which are ADF unit root test, JJ co-integration test, and Granger causality test. The results indicate the co movement of stock market volatility between China and ASEAN-5 have fairly relation among them. The result shows there are two way relations which are bidirectional causality between china and Indonesia; China and Thailand; and China and Singapore. Meanwhile, there have no causality relation between China and Malaysia; and also China and Philippines. Though, it can be concluded that there are relationship between regions in the stock market volatility

    Hyperonic mixing in five-baryon double-strangeness hypernuclei in a two-channel treatment

    Full text link
    Properties of hypernuclei ΛΛ5_{\Lambda \Lambda}^5H and ΛΛ5_{\Lambda \Lambda }^5He are studied in a two-channel approach with explicit treatment of coupling of channels ^3\text{Z}+\Lambda+\Lambda and \alpha+\Xi. Diagonal \Lambda\Lambda and coupling \Lambda\Lambda-\Xi N interactions are derived within G-matrix procedure from Nijmegen meson-exchange models. Bond energy \Delta B_{\Lambda\Lambda} in ΛΛ5_{\Lambda \Lambda}^5He exceeds significantly that in ΛΛ5_{\Lambda \Lambda}^5H due to the channel coupling. Diagonal \Xi\alpha attraction amplifies the effect, which is sensitive also to \Lambda-core interaction. The difference of the \Delta B_{\Lambda\Lambda} values can be an unambiguous signature of the \Lambda\Lambda-\Xi N coupling in \Lambda\Lambda hypernuclei. However, improved knowledge of the hyperon-nucleus potentials is needed for quantitative extraction of the coupling strength from future data on the \Lambda\Lambda hypernuclear binding energies.Comment: 11 pages with 3 figures; Phys.

    Large rivers and orogens: the evolution of the Yarlung Tsangpo–Irrawaddy system and the eastern Himalayan syntaxis

    Get PDF
    The eastern Himalayan syntaxis has experienced some of the highest rates of deformation and erosion in the orogen during the Late Cenozoic, and the Yarlung Tsangpo, Brahmaputra, Irrawaddy, Salween, and Mekong rivers are the key erosional systems in that region. The Yarlung Tsangpo drains southern Tibet and the deep Siang River gorge through the eastern Himalayan syntaxis before joining the Brahmaputra in northeastern India. It has been proposed that the Yarlung Tsangpo drained into other large rivers of southern Asia, such as the Irrawaddy, Salween and Red River. We have used uranium/lead dating and hafnium measurements of detrital zircons from Cenozoic sedimentary deposits in Central Myanmar to demonstrate that the Yarlung Tsangpo formerly drained into the Irrawaddy River in Myanmar through the eastern syntaxis, and that this ancient river system was established by (at least) the Middle–Late Eocene. The Yarlung Tsangpo–Irrawaddy river disconnected in the Early Miocene driven by increased deformation in the eastern syntaxis and headward erosion by tributaries of the Brahmaputra. Our results highlight the significance of the sedimentary record of large orogen-parallel rivers and provide key chronological constraints on landscape evolution during the Early Miocene phase of the Himalayan orogeny

    Mapping and pyramiding of two major genes for resistance to the brown planthopper (Nilaparvata lugens [Stål]) in the rice cultivar ADR52

    The brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most serious and destructive pests of rice, and can be found throughout the rice-growing areas of Asia. To date, more than 24 major BPH-resistance genes have been reported in several Oryza sativa ssp. indica cultivars and wild relatives. Here, we report the genetic basis of the high level of BPH resistance derived from an Indian rice cultivar, ADR52, which was previously identified as resistant to the whitebacked planthopper (Sogatella furcifera [Horváth]). An F2 population derived from a cross between ADR52 and a susceptible cultivar, Taichung 65 (T65), was used for quantitative trait locus (QTL) analysis. Antibiosis testing showed that multiple loci controlled the high level of BPH resistance in this F2 population. Further linkage analysis using backcross populations resulted in the identification of BPH-resistance (antibiosis) gene loci from ADR52. BPH25 co-segregated with marker S00310 on the distal end of the short arm of chromosome 6, and BPH26 co-segregated with marker RM5479 on the long arm of chromosome 12. To characterize the virulence of the most recently migrated BPH strain in Japan, preliminary near-isogenic lines (pre-NILs) and a preliminary pyramided line (pre-PYL) carrying BPH25 and BPH26 were evaluated. Although both pre-NILs were susceptible to the virulent BPH strain, the pre-PYL exhibited a high level of resistance. The pyramiding of resistance genes is therefore likely to be effective for increasing the durability of resistance against the new virulent BPH strain in Japan

    A Comparative Study of Leptospirosis and Dengue in Thai Children

    Get PDF
    Two of the most common causes of acute febrile illnesses among children in the tropics are leptospirosis and dengue. Early in illness, these two conditions are often indistinguishable and rapid laboratory confirmation of the infecting pathogen is generally not available. An enhanced ability to distinguish leptospirosis from dengue in children would guide clinicians and public health personnel in the appropriate use of limited healthcare resources
