    Hasil kajian beberapa penelitian, perdarahan pada ibu hamil dan persalinan merupakan komplikasi dari anemia selama kehamilan. Penyebab anemia menurut WHO tahun 2012 adalah defisiensi besi, kurangnya asam folat, defisiensi vitamin B12, infeksi dan penyakit keturunan. Anemia karena defisiensi besi merupakan penyebab utama dari anemia. anemia defisiensi besi dapat dilihat dari kadar hemoglobin dan kadar feritin yang rendah. Rendahnya hemoglobin disebabkan oleh pola konsumsi dan kepatuhan minum zat besi, terutama di negara berkembang. Tujuan dari penelitian ini adalah mengetahui hubungan pola konsumsi zat besi dengan kadar hemoglobin pada ibu hamil di BPS Pringsewu Lampung tahun 2015. Desain penelitian menggunakan analitik observational dengan pendekatan crossectional. Sampel dalam penelitian ini adalah ibu hamil dengan usia 32 minggu yang berjumlah 108 orang, dan alat ukur menggunakan kuesioner wawancara dan hemoglobin rapid test. Hasil penelitian diperoleh tidak ada hubungan pola konsumsi zat besi dengan kadar hemoglobin pada ibu hamil (p=0,323)

    Frequency Coded Chipless RFID Tag using Spurline Resonators

    A novel compact chipless RFID tag using spurline resonators is discussed in this paper. The detection of the tag's ID is using the spectral signature of a spurline resonator circuit. The tag has a data capacity of 8-bits in the range 2.38 to 4.04 GHz. The tag consists of a spurline multiresonating circuit and two cross polarised antennas. The prototype of the tag is fabricated on a substrate C-MET/LK4.3 of dielectric constant 4.3 and loss tangent 0.0018. The measured results show that group delay response can also be used to decode the tag’s identity

    Direct imaging constraints on planet populations detected by microlensing

    Full text link
    Results from gravitational microlensing suggested the existence of a large population of free-floating planetary mass objects. The main conclusion from this work was partly based on constraints from a direct imaging survey. This survey determined upper limits for the frequency of stars that harbor giant exoplanets at large orbital separations. Aims. We want to verify to what extent upper limits from direct imaging do indeed constrain the microlensing results. We examine the current derivation of the upper limits used in the microlensing study and re-analyze the data from the corresponding imaging survey. We focus on the mass and semi-major axis ranges that are most relevant in context of the microlensing results. We also consider new results from a recent M-dwarf imaging survey as these objects are typically the host stars for planets detected by microlensing. We find that the upper limits currently applied in context of the microlensing results are probably underestimated. This means that a larger fraction of stars than assumed may harbor gas giant planets at larger orbital separations. Also, the way the upper limit is currently used to estimate the fraction of free-floating objects is not strictly correct. If the planetary surface density of giant planets around M-dwarfs is described as df_Planet ~ a^beta da, we find that beta ~ 0.5 - 0.6 is consistent with results from different observational studies probing semi-major axes between ~0.03 - 30 AU. Having a higher upper limit on the fraction of stars that may have gas giant planets at orbital separations probed by the microlensing data implies that more of the planets detected in the microlensing study are potentially bound to stars rather than free-floating. The current observational data are consistent with a rising planetary surface density for giant exoplanets around M-dwarfs out to ~30 AU.Comment: Accepted for publication in A&A as Research Note, 3 page

    Optical properties of small polarons from dynamical mean-field theory

    Full text link
    The optical properties of polarons are studied in the framework of the Holstein model by applying the dynamical mean-field theory. This approach allows to enlighten important quantitative and qualitative deviations from the limiting treatments of small polaron theory, that should be considered when interpreting experimental data. In the antiadiabatic regime, accounting on the same footing for a finite phonon frequency and a finite electron bandwidth allows to address the evolution of the optical absorption away from the well-understood molecular limit. It is shown that the width of the multiphonon peaks in the optical spectra depends on the temperature and on the frequency in a way that contradicts the commonly accepted results, most notably in the strong coupling case. In the adiabatic regime, on the other hand, the present method allows to identify a wide range of parameters of experimental interest, where the electron bandwidth is comparable or larger than the broadening of the Franck-Condon line, leading to a strong modification of both the position and the shape of the polaronic absorption. An analytical expression is derived in the limit of vanishing broadening, which improves over the existing formulas and whose validity extends to any finite-dimensional lattice. In the same adiabatic regime, at intermediate values of the interaction strength, the optical absorption exhibits a characteristic reentrant behavior, with the emergence of sharp features upon increasing the temperature -- polaron interband transitions -- which are peculiar of the polaron crossover, and for which analytical expressions are provided.Comment: 16 pages, 6 figure

    Circadian patterns of Wikipedia editorial activity: A demographic analysis

    Get PDF
    Wikipedia (WP) as a collaborative, dynamical system of humans is an appropriate subject of social studies. Each single action of the members of this society, i.e. editors, is well recorded and accessible. Using the cumulative data of 34 Wikipedias in different languages, we try to characterize and find the universalities and differences in temporal activity patterns of editors. Based on this data, we estimate the geographical distribution of editors for each WP in the globe. Furthermore we also clarify the differences among different groups of WPs, which originate in the variance of cultural and social features of the communities of editors

    XMM observation of 1RXS J180431.1-273932: a new M-type X-ray binary with a 494 s-pulse period neutron star?

    Full text link
    Low-mass X-ray binaries are binary systems composed of a compact object and a low-mass star. Recently, a new class of these systems, known as symbiotic XX-ray binaries (with a neutron star with a M-type giant companion), has been discovered. Here, we present long-duration XMM{\it XMM} observations of the source 1RXS J180431.1-273932. Temporal and spectral analysis of the source was performed along with a search for an optical counterpart. We used a Lomb-Scargle periodogram analysis for the period search and evaluated the confidence level using Monte-Carlo simulations. The source is characterized by regular pulses so that it is most likely a neutron star. A modulation of 494.1±0.2494.1\pm0.2 s (3σ\sigma error) was found with a confidence level of >>99%. Evidence of variability is also present, since the data show a rate of change in the signal of 7.7×104\sim -7.7\times 10^{-4} counts s1^{-1} hr1^{-1}. A longer observation will be necessary in order to determine if the source shows any periodic behavior. The spectrum can be described by a power law with photon index Γ1\Gamma\sim 1 and a Gaussian line at 6.6 keV. The X-ray flux in the 0.2--10 keV energy band is 5.4×10125.4\times 10^{-12} erg s1^{-1} cm2^{-2}. The identification of an optical counterpart (possibly an M6III red-giant star with an apparent visual magnitude of 17.6\simeq 17.6) allows a conservative distance of 10\sim 10 kpc to be estimated. Other possibilities are also discussed. Once the distance was estimated, we got an XX-ray luminosity of L_X\ut<6\times 10^{34} erg s1^{-1}, which is consistent with the typical XX-ray luminosity of a symbiotic LMXB system.Comment: in press on A&

    Bandwidth-Controlled Insulator-Metal Transition and Correlated Metallic State in 5dd Transition Metal Oxides Srn+1_{n+1}Irn_{n}O3n+1_{3n+1} (nn=1, 2, and \infty)

    We investigated the electronic structures of the 5dd Ruddlesden-Popper series Srn+1_{n+1}Irn_{n}O3n+1_{3n+1} (nn=1, 2, and \infty) using optical spectroscopy and first-principles calculations. As 5dd orbitals are spatially more extended than 3dd or 4dd orbitals, it has been widely accepted that correlation effects are minimal in 5dd compounds. However, we observed a bandwidth-controlled transition from a Mott insulator to a metal as we increased nn. In addition, the artificially synthesized perovskite SrIrO3_{3} showed a very large mass enhancement of about 6, indicating that it was in a correlated metallic state
