Published: November 2016

Akhir-akhir ini bioprospeksi mikroorganisme laut semakin populer dan banyak diminati karena potensinya yang menjanjikan sebagai sumber komponen bioaktif baru. Identifikasi mikroorganisme merupakan salah satu tahapan yang penting dalam bioprospeksi. Perkembangan identifikasi mikroba diawali dengan identifikasi melalui ciri-ciri morfologi, fisiologi, dan metabolisme. Namun adanya kekurangan-kekurangan metode ini yaitu berupa ketidakakuratan dan waktu identifikasi yang lama menjadikan metode secara molekuler lebih berkembang. Pada bakteri, 16S ribosom deoxyribonucleic acid (rDNA) mempunyai daerah sekuen yang konservatif sehingga dapat digunakan untuk menduga hubungan kekerabatan secara alami antar spesies. Sedangkan pada kapang digunakan 18S rDNA dan daerah internal transcribed spacer (ITS) untuk identifikasinya. Tahapan identifikasi dengan metode molekuler meliputi ekstraksi deoxyribonucleic acid (DNA), amplifikasi DNA, sekuensing, analisis hasil sekuen, dan pembuatan pohon filogenetik. Balai Besar Riset Pengolahan Produk dan Bioteknologi Kelautan dan Perikanan (BBRP2B-KP) memiliki koleksi mikroba potensial penghasil enzim kitosanase, kitinase, dan protease dari berbagai sampel dari lingkungan laut. Berdasarkan pohon filogenetik beberapa isolat koleksi memiliki kemiripan 87–96% dengan Staphylococcus caprae, Stenotrophomonas maltophilia, Acinetobacter sp., Bacillus licheniformis, Geobacillus stearothermophilus.

Increasing fish consumption value should be supported by enhancing the safety and quality offish products. Microbiological level is most of importance since every food contains microorganismswhich could multiplicate due to temperature abuse and time delay during handling and processing.Risk assessment is a structurally and scientifically based approach aimed to protect consumerfrom risk (hazard) particularly microbiological hazard when consuming certain food. Microbiologicalrisk assessment of fishery products have not been structurally developed in Indonesia, eventhoughseveral initial data on hazard identification have been available. As an attempt to build an integratedrisk assessment, a model for microbiological risk of pathogenic Vibrio parahaemolyticus inshrimp will be proposed in this article. The available data could be used as a starting point whileother required data could be collected in collaboration with other related institutions.

The Traditional Lecture: A case of Academic Chuunibyou?
Authors: Crawford Russell 
Published: November 2016

Chuunibyou: a Japanese slang term where people with chuunibyou act out by looking down on others resulting in a subculture-type preference for minor trends thereby seeking a "cool" factor. To this author, an apt description of how the lecture has been unfairly viewed in recent years as a poor pedagogic tool, in essence, an academic chuunibyou! My central belief here is that the lecture is a useful, relevant pedagogically focused application of the professional teacher working their craft and can be viewed in essence as facilitating a powerful “pedagogy of gesture”

ABSTRACT
We use time-domain electromagnetic simulations to determine the spectral characteristics of the Hydrogen Epoch of Reionization Arrays (HERA) antenna. These simulations are part of a multi-faceted campaign to determine the effectiveness of the dish’s design for obtaining a detection of redshifted 21 cm emission from the epoch of reionization. Our simulations show the existence of reflections between HERA’s suspended feed and its parabolic dish reflector that fall below −40 dB at 150 ns and, for reasonable impedance matches, have a negligible impact on HERA’s ability to constrain EoR parameters. It follows that despite the reflections they introduce, dishes are effective for increasing the sensitivity of EoR experiments at a relatively low cost. We find that electromagnetic resonances in the HERA feed’s cylindrical skirt, which is intended to reduce cross coupling and beam ellipticity, introduces significant power at large delays (−40 dB at 200 ns), which can lead to some loss of measurable Fourier modes and a modest reduction in sensitivity. Even in the presence of this structure, we find that the spectral response of the antenna is sufficiently smooth for delay filtering to contain foreground emission at line-of-sight wave numbers below k
∥ ≲ 0.2 h Mpc−1, in the region where the current PAPER experiment operates. Incorporating these results into a Fisher Matrix analysis, we find that the spectral structure observed in our simulations has only a small effect on the tight constraints HERA can achieve on parameters associated with the astrophysics of reionization.
A COMMON ORIGIN FOR GLOBULAR CLUSTERS AND ULTRA-FAINT DWARFS IN SIMULATIONS OF THE FIRST GALAXIES

ABSTRACT
In this paper, the first in a series on galaxy formation before reionization, we focus on understanding what determines the size and morphology of stellar objects in the first low-mass galaxies, using parsec-scale cosmological simulations performed with an adaptive mesh hydrodynamics code. Although the dense gas in which stars are formed tends to have a disk structure, stars are found in spheroids with little rotation. Halos with masses between

and

form stars stochastically, with stellar masses in the range

to

. We observe, nearly independent of stellar mass, a large range of half-light radii for the stars, from a few parsecs to a few hundred parsecs and surface brightnesses and mass-to-light ratios ranging from those typical of globular clusters to ultra-faint dwarfs. In our simulations, stars form in dense stellar clusters with high gas-to-star conversion efficiencies and rather uniform metallicities. A fraction of these clusters remain bound after the gas is removed by feedback, but others are destroyed, and their stars, which typically have velocity dispersions of 20–40 km s−1, expand until they become bound by the dark matter halo. We thus speculate that the stars in ultra-faint dwarf galaxies may show kinematic and chemical signatures consistent with their origin in a few distinct stellar clusters. On the other hand, some globular clusters may form at the center of primordial dwarf galaxies and may contain dark matter, perhaps detectable in the outer parts.

ABSTRACT
We present the results of SPT-GMOS, a spectroscopic survey with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. The targets of SPT-GMOS are galaxy clusters identified in the SPT-SZ survey, a millimeter-wave survey of 2500 deg2 of the southern sky using the South Pole Telescope (SPT). Multi-object spectroscopic observations of 62 SPT-selected galaxy clusters were performed between 2011 January and 2015 December, yielding spectra with radial velocity measurements for 2595 sources. We identify 2243 of these sources as galaxies, and 352 as stars. Of the galaxies, we identify 1579 as members of SPT-SZ galaxy clusters. The primary goal of these observations was to obtain spectra of cluster member galaxies to estimate cluster redshifts and velocity dispersions. We describe the full spectroscopic data set and resulting data products, including galaxy redshifts, cluster redshifts, and velocity dispersions, and measurements of several well-known spectral indices for each galaxy: the equivalent width, W, of [O ii] λλ3727, 3729 and H-δ, and the 4000 Å break strength, D4000. We use the spectral indices to classify galaxies by spectral type (i.e., passive, post-starburst, star-forming), and we match the spectra against photometric catalogs to characterize spectroscopically observed cluster members as a function of brightness (relative to m
⋆). Finally, we report several new measurements of redshifts for ten bright, strongly lensed background galaxies in the cores of eight galaxy clusters. Combining the SPT-GMOS data set with previous spectroscopic follow-up of SPT-SZ galaxy clusters results in spectroscopic measurements for >100 clusters, or ∼20% of the full SPT-SZ sample.
From prosumer to prodesigner: Participatory news consumption
Authors: Hernández-Serrano María-José , Renés-Arellano Paula , Graham Gary , Greenhill Anita 
Published: November 2016

New democratic participation forms and collaborative productions of diverse audiences have emerged as a result of digital innovations in the online access to and consumption of news. The aim of this paper is to propose a conceptual framework based on the possibilities of Web 2.0. Outlining the construction of a “social logic”, which combines computer and communicative logics, the conceptual framework is theoretically built to explore the evolution of news consumption from a pure circulation of designed products towards a global conversation of proactive news designers. Then, the framework was tested using an empirical database built by the Pew Research Centre, which investigates the future of the news industry, through a large-scale survey with adults. Results show significant differences (by age, gender and educational level) in the forms of participation, access and consumption of news. However, whilst immersed in the culture of Web 2.0 there is a low-level of user participation in news production; far from being proactive news designers, findings suggest that citizens are still located in the lower participatory levels of our conceptual framework. Conclusions suggest there is a need for media education providers to carry out training initiatives according to the social logic possibilities through proposed guidelines.

Este marco teórico se ha testeado a través de una base de datos empírica del Instituto de investigación PEW, que mediante una encuesta con adultos a gran escala permite analizar el futuro de la industria de las noticias. Los resultados muestran diferencias significativas (por edad, sexo y nivel educativo) en las formas de participación, acceso y consumo de noticias. Aunque existe una cultura Web 2.0, hay un bajo nivel de participación de usuarios en la producción de noticias; lejos de ser diseñadores proactivos de noticias, los hallazgos sugieren que la mayoría de ciudadanos se sitúan en los niveles de participación más bajos del marco conceptual propuesto. Se concluye sugiriendo la necesidad de que los responsables de la educación en medios desarrollen iniciativas formativas acordes a las posibilidades de la lógica social a través de la propuesta de pautas.

Abstract. Two aerosol samples collected at King Sejong Korean scientific research station, Antarctica, on 9 December 2011 in the austral summer (sample S1) and 23 July 2012 in the austral winter (sample S2), when the oceanic chlorophyll a levels on the collection days of the samples were quite different, by  ∼  19 times (2.46 vs. 0.13 µg L−1, respectively), were investigated on a single-particle basis using quantitative energy-dispersive electron probe X-ray microanalysis (ED-EPMA), called low-Z particle EPMA, Raman microspectrometry (RMS), and attenuated total reflection Fourier transform infrared (ATR-FTIR) imaging techniques to obtain their characteristics based on the elemental chemical compositions, molecular species, and mixing state. X-ray analysis showed that the supermicron summertime and wintertime Antarctic aerosol samples have different elemental chemical compositions, even though all the individual particles analyzed were sea spray aerosols (SSAs); i.e., the contents of C, O, Ca, S, and Si were more elevated, whereas Cl was more depleted, for sample S1 than for sample S2. Based on qualitative analysis of the chemical species present in individual SSAs by the combined application of RMS and ATR-FTIR imaging, different organic species were observed in samples S1 and S2; i.e., Mg hydrate salts of alanine were predominant in samples S1 and S2, whereas Mg salts of fatty acids internally mixed with Mg hydrate salts of alanine were significant in sample S2. Although CaSO4 was observed significantly in both samples S1 and S2, other inorganic species, such as Na2SO4, NaNO3, Mg(NO3)2, SiO2, and CH3SO3Mg, were observed more significantly in sample S1, suggesting that those compounds may be related to the higher phytoplankton activity in summer.

Abstract. Reactive nitrogen (Nr  =  NO, NO2, HONO) and volatile organic carbon emissions from oil and gas extraction activities play a major role in wintertime ground-level ozone exceedance events of up to 140 ppb in the Uintah Basin in eastern Utah. Such events occur only when the ground is snow covered, due to the impacts of snow on the stability and depth of the boundary layer and ultraviolet actinic flux at the surface. Recycling of reactive nitrogen from the photolysis of snow nitrate has been observed in polar and mid-latitude snow, but snow-sourced reactive nitrogen fluxes in mid-latitude regions have not yet been quantified in the field. Here we present vertical profiles of snow nitrate concentration and nitrogen isotopes (δ15N) collected during the Uintah Basin Winter Ozone Study 2014 (UBWOS 2014), along with observations of insoluble light-absorbing impurities, radiation equivalent mean ice grain radii, and snow density that determine snow optical properties. We use the snow optical properties and nitrate concentrations to calculate ultraviolet actinic flux in snow and the production of Nr from the photolysis of snow nitrate. The observed δ15N(NO3−) is used to constrain modeled fractional loss of snow nitrate in a snow chemistry column model, and thus the source of Nr to the overlying boundary layer. Snow-surface δ15N(NO3−) measurements range from −5 to 10 ‰ and suggest that the local nitrate burden in the Uintah Basin is dominated by primary emissions from anthropogenic sources, except during fresh snowfall events, where remote NOx sources from beyond the basin are dominant. Modeled daily averaged snow-sourced Nr fluxes range from 5.6 to 71  ×  107 molec cm−2 s−1 over the course of the field campaign, with a maximum noontime value of 3.1  ×  109 molec cm−2 s−1. The top-down emission estimate of primary, anthropogenic NOx in Uintah and Duchesne counties is at least 300 times higher than the estimated snow NOx emissions presented in this study. Our results suggest that snow-sourced reactive nitrogen fluxes are minor contributors to the Nr boundary layer budget in the highly polluted Uintah Basin boundary layer during winter 2014.
