    We have carried out a millimeter interferometric continuum survey toward 7 YSOs in the MBM 12 cloud. Thermal emissions associated with 2 YSOs were detected above the 3-σ\sigma level at 2.1 mm, and one also showed a 1.3 mm thermal emission. Another object was marginally detected at 2.1 mm. Spectral energy distributions of the YSOs are well fitted by a simple power-law disk model. Masses of the circumstellar disks are estimated to be an order of 0.05 M_{\sun}. The circumstellar disks in the MBM 12 cloud have properties in common with the disks in nearby star-forming regions, in terms of disk parameters such as a disk mass, as well as an infrared excess.Comment: 9 pages, 3 figures, accepted by ApJ Letter

    Future directions in aeropropulsion technology

    Get PDF
    Future directions in aeropropulsion technology that have been identified in a series of studies recently sponsored by the U.S. Government are discussed. Advanced vehicle concepts that could become possible by the turn of the century are presented along with some of their projected capabilities. Key building-block propulsion technologies that will contribute to making these vehicle concepts a reality are discussed along with projections of their status by the year 2000. Some pertinent highlights of the NASA aeropropulsion program are included in the discussion

    On the occurrence of Schistidium subconfertum and S. succulentum in Europe

    Full text link
    We here clarify that currently there are no records of the Asiatic Schistidium subconfertum (Broth.) Deguchi in Europe. The only European specimen referred to this species represents S. succulentum Ignatova & H.H. Blom, a taxon rather recently described from Caucasus. Furthermore, we provide new records of the latter species in the French and Swiss Alps. The two species share a reduced peristome, but can be distinguished by characteristics of the gametophyte such as lamina thickness (unistratous in S. subconfertum versus partially bistratous in S. succulentum) and shallowly versus strongly projecting costa

    The Current and Desirable States of School Management to Enhancing Creative Thinking Characteristics of Elementary School Students

    Get PDF
    This study investigated the thinking framework of school management to enhance creative thinking characteristics of elementary school students, and to explore the current and desirable states of school management that help stimulate creative thinking characteristics of the elementary school students. The participants were school directors, vice directors, heads of administrations, teachers and students in 396 schools under Office of the Basic Education Commission. The  participants were required to complete the questionnaires and the interviews. The results of this study revealed that there were five tasks of the thinking participate in framework of school management which performed following the planning, implementation and evaluation processes such as, Course Development Task, Learning Process Management Task, Measurement and Evaluation Task, Learning Sources Development Task and Student Affairs. These tasks may have encouraged all the characteristics reflecting creative thinking of the elementary school students: curiosity, persistence, freedom, imagination, innovative though, aesthetics, risk taking, creative problem solving and intuition. The results also indicated that the current state of school management was found at a high level ( X = 3.73, S.D. = 0.67), while the desirable state of school management was found at the highest level ( X = 4.60, S.D. = 0.44)

    Improving patient safety, health data accuracy, and remote self-management of health through the establishment of a biometric-based global UHID

    Healthcare systems globally continue to face challenges surrounding patient identification. Consequences of misidentification include incomplete and inaccurate electronic patient health records potentially jeopardizing patients\u27 safety, a significant amount of cases of medical fraud because of inadequate identification mechanisms, and difficulties affiliated with the value of remote health self-management application data being aggregated accurately into the user\u27s Electronic Health Record (EHR). We introduce a new technique of user identification in healthcare capable of establishing a global identifier. Our research has developed algorithms capable of establishing a Unique Health Identifier (UHID) based on the user\u27s fingerprint biometric, with the utilization of facial-recognition as a secondary validation step before health records can be accessed. Biometric captures are completed using standard smartphones and Web cameras in a touchless method. We present a series of experiments to demonstrate the formation of an accurate, consistent, and scalable UHID. We hope our solution will aid in the reduction of complexities associated with user misidentification in healthcare resulting in lowering costs, enhancing population health monitoring, and improving patient-safety

    On two subspecies of \u3cem\u3eMesobuthus eupeus\u3c/em\u3e (C. L. Koch, 1839) in Turkey (Scorpiones: Buthidae)

    Examination of 268 specimens of Mesobuthus eupeus eupeus (C. L. Koch, 1839) and 1765 specimens of M. eupeus phillipsii (Pocock, 1889) from 163 localities, 92 of them in Turkey, has enabled us to establish distribution of the two subspecies and limits of their ranges in southeastern Turkey. A map of distribution of these subspecies in Turkey and a key to Turkish Mesobuthus species and subspecies are provided. Buthus eupeus philippovitschi Birula, 1905 is synonymized with Mesobuthus eupeus eupeus, and Buthus eupaeus mesopotamicus Penther, 1912 is synonymized with Mesobuthus eupeus phillipsii
