The status of Galactic field lambda Bootis stars in the post-Hipparcos era

The lambda Bootis stars are Population I, late B to early F-type stars, with moderate to extreme (up to a factor 100) surface underabundances of most Fe-peak elements and solar abundances of lighter elements (C, N, O, and S). To put constraints on the various existing theories that try to explain these peculiar stars, we investigate the observational properties of lambda Bootis stars compared to a reference sample of normal stars. Using various photometric systems and Hipparcos data, we analyze the validity of standard photometric calibrations, elemental abundances, and Galactic space motions. There crystallizes a clear picture of a homogeneous group of Population I objects found at all stages of their main-sequence evolution, with a peak at about 1 Gyr. No correlation of astrophysical parameters such as the projected rotational velocities or elemental abundances with age is found, suggesting that the a-priori unknown mechanism, which creates lambda Bootis stars, works continuously for late B to early F-type stars in all stages of main-sequence evolution. Surprisingly, the sodium abundances seem to indicate an interaction between the stars and their local environment.Comment: 14 pages, 9 figures, accepted by MNRA

Sistem Informasi Wedding Planner Berbasis Web

Currently, wedding organizers are being sought after by prospective brides who want to realize their dream wedding. Therefore the bride must have information about the wedding organizer in order to choose the concept or things that are needed for the wedding. The Internet becomes the main way for the public in the search for information, one of the sources of such information is the website. The most sought-after information required is the wedding organizer. The number of wedding organizer websites is already very much so that the bride has many references, but if we have to open one by one website it will take a lot of time and not necessarily the things desired by the bride and groom is available in the WO. To solve the problem, we need a website that becomes a unifying place for all WO. The method used in making wedding planner website is planning, analysis, design, and implementation. Website wedding planner is made with a web-based program that can be accessed by anyone, anywhere, and anytime. Website Wedding Planner is designed with PHP and MySQL database. Making a wedding planner website is aimed to accommodate vendors or WO to promote products on the website more effectively and efficiently and can provide complete information for wedding planning for the bride and groom

PCR–electrospray ionization mass spectrometry (PCR-ESI/MS), suatu peralatan baru yang mampu mendeteksi hampir semua mikroorganisme patogen, namun belum pernah digunakan di Indonesia. Tujuan penelitian ini untuk memperoleh pengalaman dengan PCR/ESI-MS dan panel food borne pathogen, mengetahui kelebihan dan kelemahan teknologi ini. Rancangan penelitian potong lintang, menggunakan spesimen dari poliklinik anak, dilakukan dari bulan juli 2012 hingga desember 2012, dan akhirnya 24 spesimen diperiksa dengan PCR/ESI-MS. Karakteristik diare terdiri dari 12 dengan lendir, 3 diare berdarah dan 20 hanya diare cair saja. Pada sebagian besar kasus dijumpai lebih dari satu bakteri. Bakteri E. coli FDA29 ditemukan pada kasus disertai demam dan sakit Perut, namun tidak ada pada kasus tanpa kelainan tersebut. Jenis bakteri dengan PCR/ESI-MS berbeda dengan kultur. Metoda ini dapat mendeteksi bakteri dalam waktu 24 jam dan sangat bermanfaat pada wabah. Berdasarkan kemampuan metoda ini untuk mendeteksi beberapa bakteri dari satu spesimen, tampaknya biayanya tidak lebih mahal dibanding kultur. Metoda ini sangat bermanfaat untuk surveilans dalam hal menemukan kesamaaan antara penyebab penyakit dan pejamu. PCR–electrospray ionization mass spectrometry (PCR-ESI/MS), a new equipment that can detect almost all human patogenic microorganism, but never used before in Indonesia.The aim of this study to get experience with PCR/ESI-MS and panel food borne pathogen, to know the profile of bacteria that caused diarhea by PCR/ESI-MS, and know the advantage and handicapped of this equipment.Study design was descriptive cross sectional, using specimen from Child ambulatory clinic, was done from July 2012 until December 2012 and finally 24 was examined with PCR/ESI-MS. Clinical characteristic consist of fever 9 (37,5%), vomiting 17 (70.8%)and abdominal pain 11 (45.8%). Mayority (75%) got diarhea from 3-5 daily. Characteristic of diarhea, 12 cases with mucus, 3 cases bloody diarhea and 20 cases only liquid faeces. In most cases, we found multiple bacteria . Bacteria E. coli FDA29 was detected on cases with fever and abdominal pain but not found in cases without those manifestation. Type of bacteria in this study was different with cultur result. This method can detect bacteria in 24 hours, and very useful in outbreak, and if we calculate the cost and the ability of this metod to detect several bacteria from single specimen, it seems nearly the same. It seems that this method will be very useful for surveilans ie to find similarity between agent and host

Weak interactions of supersymmetric staus at high energies

Neutrino telescopes may have the potential to detect the quasi-stable staus predicted by supersymmetric models. Detection depends on stau electromagnetic energy loss and weak interactions. We present results for the weak interaction contribution to the energy loss of high energy staus as they pass through rock. We show that the neutral current weak interaction contribution to the energy loss increases with energy, but it is much smaller than the photonuclear energy loss, however, the charged current contribution may become the dominant process above the energy of $\sim 10^9$ GeV, depending on the parameters of the model. As a consequence, the stau range may be reduced above $\sim 10^9$ GeV as compared to the range neglecting weak interactions. We contrast this with the tau range which is barely changed with the inclusion of charged current interactions.Comment: 7 pages, 8 figures, version to be publishe
