    In this paper, we prove the boundedness of Bessel-Riesz operators on generalized Morrey spaces. The proof uses the usual dyadic decomposition, a Hedberg-type inequality for the operators, and the boundedness of Hardy-Littlewood maximal operator. Our results reveal that the norm of the operators is dominated by the norm of the kernels.Comment: 10 page

    Mesoscale numerical approach to predict macroscale fluid flow problems

    Get PDF
    We present a detailed analysis of the lattice Boltzmann method to simulate an incompressible fluid flow problem. Thorough derivation of macroscopic hydrodynamics equations from the continuous Boltzmann equation is performed. After showing how the formulation of the mesoscale particle dynamics fits in to the framework of lattice Boltzmann simulations, numerical results of isothermal, thermal and multiphase fluid flow are presented to highlight the applicability of the approach. The objective of the paper is to gain better understanding of this relatively new approach for applied engineering problems in fluid transport phenomena

    The research objectives of the study are to investigate whether there are any positive relationships between CFP and CSR under the slack resource theory and to investigate whether there are any positive relationships between CSR and CFP under good management theory by integrating concept of strategic management into the definition of CSR as sustainable corporate performance including economy, social, and environment. To answer the research questions of this study, questionnaire-based survey research design was used. The questionnaires that include items representing variables in this study (corporate social performance, corporate financial performance, business environment, strategy, organization structure, and control system) were sent to the respondents who are managers of state-owned companies (BUMN) and private- owned companies using post and e-mail services. There is a positive relationship between CFP and CSP under the slack resource theory and under good management theory. Keywords: corporate social performance, corporate financial performance, business environment, strategy, organization structure, and control system, slack resource theory, good management theor

    Evidence for dynamic and multiple roles for huntingtin in Ciona intestinalis

    Although mutations in the huntingtin gene (HTT) due to poly-Q expansion cause neuropathology in humans (Huntington's disease; HD), the normal function(s) of the gene and its protein (HTT) remain obscure. With new information from recently sequenced invertebrate genomes, the study of new animal models opens the possibility of a better understanding of HTT function and its evolution. To these ends, we studied huntingtin expression pattern and dynamics in the invertebrate chordate Ciona intestinalis. Ciona huntingtin (Ci-HTT) shows a biphasic expression pattern during larval development and prior to metamorphosis. A single form of huntingtin protein is present until the early larval stages, at which time two different mass proteins become evident in the metamorphically competent larva. An antibody against Ci-HTT labeled 50 cells in the trunk mesenchyme regions in pre-hatching and hatched larvae and probably represents the distribution of the light form of the protein. Dual labeling with anti-Ci-HTT and anti-aldoketoreductase confirmed the presence of Ci-HTT in mesenchyme cells. Suppression of Ci-HTT RNA by a morpholino oligonucleotide reduced the number and apparent mobility of Ci-HTT positive cells. In Ciona, HTT expression has a dynamic temporal and spatial expression pattern that in ontogeny precedes metamorphosis. Although our results may reflect a derived function for the protein in pre- and post-metamorphic events in Ciona, we also note that as in vertebrates, there is evidence for multiple differential temporal expression, indicating that this protein probably has multiple roles in ontogeny and cell migration. © 2013 Springer-Verlag Berlin Heidelberg

    The purpose of this study was to analysis the strategy of “Irma Jaya Rattan Furniture”. SWOT was used to analyse the collected data. The results showed that Irma Jaya Rattan the development influenced by internal and external factors. Internal factors had a total value of 3.61 with scores of strength 2.59 and weakness 1.02, respectively. This shows the strength factor was greater than the weakness, while external factors have a total value of 2.61 with scores of opportunities 2.04 and threat 0.57, respectively. This showed that the opportunities factor was greater than the threat. Therefore the suitable alternative strategies for the development of Rattan Furniture Industry Irma Jaya is by using SO, Irma Jaya Rattan Furniture Industry can create a strategy that uses force to take advantage of existing opportunities

    : The Concept of Humanistic Education in the Development of Islamic Education.This research examines the concept of humanistic education in the development of Islamic education. What is the main concern of today\u27s global struggle is the degrading humanity and diminishing the spirit of religiosity and human values. Globalization turns the world to be more transparent and widely open, which is akin to global village without limited by any boundary. To anticipate this situation, humanistic education is urgently required in Islamic education development. The author concludes that humanistic education in the framework of Islamic education is a unique, independent and creative system of humanizing human. In other words, it views humans as creature of God with all potentials, and construct human character that respect human dignity as being the perfect human creatures

    Low-temperature partial transient liquid phase diffusion bonding of Al/Mg2Si metal matrix composite to AZ91D using Al-based interlayer

    Get PDF
    Partial transient liquid phase diffusion bonding of an aluminium metal matrix composite (Al/Mg2Si) to magnesium alloy (AZ91D) was performed using two heating rates. The influence of different heating rates on the microstructure, microhardness and shear strength has been studied. With a decrease in heating rate from 20 to 2 °C/min, the Mg content in the bond line decreased and the microstructure was altered. The composition and microstructure of the joined areas were examined by X-ray diffraction (XRD) and scanning electron microscopy equipped with energy dispersive X-ray spectroscopy (EDS). It was found that a heating rate of 2 °C/min resulted in an increasing in the shear strength of the joints. The kinetics of the bonding process accelerated due to the increase of solute diffusivity through grain boundaries of the metal matrix composite. Results suggest that Mg and Si contained in the interlayer favours the partial disruption of oxide films, facilitating the bonding process
