Synthesis of bulk, dense, nanocrystalline yttrium aluminum garnet from amorphous powders

Amorphous powders of Al2O3x2014;37.5 mol% Y2O3 (yttrium aluminum garnet (YAG)) were prepared by coprecipitation, decomposed at 800xB0;C, and hot-pressed uniaxally at low temperature (600xB0;C) and a moderate pressure (750 MPa). Optimum conditions yielded microstructures with only 2% porosity and partial crystallization of YAG. Further processing using high quasi-hydrostatic pressure (1 GPa) at 1000xB0;C enabled the production of fully crystallized YAG with gt;96% relative density and a nanocrystalline grain size of x223C;70 nm. 13

Have we detected the most luminous ULX so far?

We report the XMM-Newton detection of a moderately bright X-ray source superimposed on the outer arms of the inactive spiral galaxy MCG-03-34-63 (z=0.0213). It is clearly offset from the nucleus (by about 19'') but well within the D25 ellipse of the galaxy, just along its bar axis. The field has also been observed with the HST enabling us to compute a lower limit of > 94 on the X-ray to optical flux ratio which, together with the X-ray spectrum of the source, argues against a background AGN. On the other hand, the detection of excess X-ray absorption and the lack of a bright optical counterpart argue against foreground contamination. Short-timescale variability is observed, ruling out the hypothesis of a particularly powerful supernova. If it is associated with the apparent host galaxy, the source is the most powerful ULX detected so far with a peak luminosity of 1.35x10^41 erg/s in the 0.5-7 keV band. If confirmed by future multi-wavelength observations, the inferred bolometric luminosity (about 3x10^41 erg/s) requires a rather extreme beaming factor (larger than 115) to accommodate accretion onto a stellar-mass black hole of 20 solar masses and the source could represent instead one of the best intermediate-mass black hole candidate so far. If beaming is excluded, the Eddington limit implies a mass of >2300 solar masses for the accreting compact object.Comment: MNRAS Letters in press; minor correction at the end of Section

Accretion disc-corona and jet emission from the radio-loud narrow-line Seyfert 1 galaxy RX J1633.3+4719

We perform X-ray/ultraviolet (UV) spectral and X-ray variability studies of the radio-loud narrow-line Seyfert 1 (NLS1) galaxy RX J1633.3+4719 using XMM-Newton and Suzaku observations from 2011 and 2012. The 0.3-10 keV spectra consist of an ultrasoft component described by an accretion disc blackbody (kT_in = 39.6^{+11.2}_{-5.5} eV) and a power law due to the thermal Comptonization ({\Gamma} = 1.96^{+0.24}_{-0.31}) of the disc emission. The disc temperature inferred from the soft excess is at least a factor of 2 lower than that found for the canonical soft excess emission from radio-quiet NLS1s. The UV spectrum is described by a power law with photon index 3.05^{+0.56}_{-0.33}. The observed UV emission is too strong to arise from the accretion disc or the host galaxy, but can be attributed to a jet. The X-ray emission from RX J1633.3+4719 is variable with fractional variability amplitude $F_{\rm var}$=13.5$\pm1.0$ per cent. In contrast to radio-quiet active galactic nuclei (AGN), X-ray emission from the source becomes harder with increasing flux. The fractional rms variability increases with energy and the rms spectrum is well described by a constant disc component and a variable power-law continuum with the normalization and photon index being anticorrelated. Such spectral variability cannot be caused by variations in the absorption and must be intrinsic to the hot corona. Our finding of possible evidence for emission from the inner accretion disc, jet and hot corona from RX J1633.3+4719 in the optical to X-ray bands makes this object an ideal target to probe the disc-jet connection in AGN.Comment: 12 pages, 11 figures, 3 tables, Published in MNRA

Embedded AGN and star formation in the central 80 pc of IC 3639

[Abridged] Methods: We use interferometric observations in the $N$-band with VLTI/MIDI to resolve the mid-IR nucleus of IC 3639. The origin of the nuclear infrared emission is determined from: 1) the comparison of the correlated fluxes from VLTI/MIDI with the fluxes measured at subarcsec resolution (VLT/VISIR, VLT/ISAAC); 2) diagnostics based on IR fine-structure line ratios, the IR continuum emission, IR bands produced by polycyclic aromatic hydrocarbons (PAH) and silicates; and 3) the high-angular resolution spectral energy distribution. Results: The unresolved flux of IC 3639 is $90 \pm 20\, \rm{mJy}$ at $10.5\, \rm{\mu m}$, measured with three different baselines in VLTI (UT1-UT2, UT3-UT4, and UT2-UT3; $46$-$58\, \rm{m}$), making this the faintest measurement so far achieved with mid-IR interferometry. The correlated flux is a factor of $3$-$4$ times fainter than the VLT/VISIR total flux measurement. The observations suggest that most of the mid-IR emission has its origin on spatial scales between $10$ and $80\, \rm{pc}$ ($40$-$340\, \rm{mas}$). A composite scenario where the star formation component dominates over the AGN is favoured by the diagnostics based on ratios of IR fine-structure emission lines, the shape of the IR continuum, and the PAH and silicate bands. Conclusions: A composite AGN-starburst scenario is able to explain both the mid-IR brightness distribution and the IR spectral properties observed in the nucleus of IC 3639. The nuclear starburst would dominate the mid-IR emission and the ionisation of low-excitation lines (e.g. [NeII]$_{12.8 \rm{\mu m}}$) with a net contribution of $\sim 70\%$. The AGN accounts for the remaining $\sim 30\%$ of the mid-IR flux, ascribed to the unresolved component in the MIDI observations, and the ionisation of high-excitation lines (e.g. [NeV]$_{14.3 \rm{\mu m}}$ and [OIV]$_{25.9 \rm{\mu m}}$).Comment: Accepted for publication in A&

Profil Kinerja Keunggulan Bersaing Industri Manufakturing Kecil dan Menengah di Jawa Barat dan Banten dalam Era Pelaksanaan CHINA-ASEAN Free Trade Area

Globalisasi dan terbukanya pasar nasional dari pemain‐pemain global membuat kondisi persaingan USAha yang semakin ketat. Free Trade Area (FTA) menjadi sebuah model perdagangan regional, termasuk ASEAN. ASEAN merupakan salah satu regional yang strategis dalam kajian ekonomi Internasional, seperti dalam Ariyasajjakorn, Gander, Ratanakomut, & Reynolds (2009). Situasi tentu mendorong pelaku USAha nasional untuk selalu mengukur kinerjanya dan mendapatkan informasi secara cepat.Dengan berlakunya perjanjian CAFTA pada tahun 2010, maka produk‐produk RRC, akan dengan bebasnya masuk ke pasaran di Indonesia. Industri‐industri di RRC saat ini dikenal memiliki tingkat effisiensi yang sangat tinggi di satu pihak dan tingkat produktivitas yang tinggi di lain pihak. Hal ini tentunya mempengaruhi daya saing dan dorongan ekspansi yang cukup tinggi untuk masuk ke pasar di luar RRC dengan harga yang jauh lebih murah. Industri domestik Indonesia menjadi kehilangan daya saingnya terutama dari sisi harga bila dibandingkan dengan produk‐produk RRC. Hal ini berimbas juga kepada industri‐industri kecil dan menengah.Penelitian ini bertujuan untuk mengkaji pengaruh perjanjian CAFTA terhadap tingkat pertumbuhan IMKM di Jawa Barat, penyusunan kluster IMKM di Jawa Barat berdasarkan kinerja, merumuskan ukuran kinerja IMKM di Jawa Barat..Penelitian ini akan memberikan kontribusi yang signifikan dalam merumuskan kinerja IMKM secara khusus, dan UMKM secara umum. Selain itu juga berkontribusi dalam menyusun kajian faktor‐faktor yang berpengaruh terhadap kinerja Perusahaan. Hasil yang dicapai ini diharapkan bermanfaat bagi pelaku IMKM, pemerintah, dan sektor industri pada umumnya untuk menyusun strategi bersaing dalam menghadapi ACFTA.Dalam masa krisis ternyata yang bertahan bukan Usaha Besar melainkan Usaha Kecil dan Menengah. Demikian juga bila dikalkulasi dari sisi untung rugi, macetnya pinjaman satu unit Usaha Besar yang sekian triliun rupiah jumlahnya sama setara dengan pinjaman beratus Unit UKM. Padahal dari pengalaman UKM yang ‘ngemplang\u27 hutangnya tidak sebanyak Usaha Besar. Katakanlah dari seratus UKM yang ‘ngemplang\u27 sebanyak 25 % tetap saja masih di bawah UB yang ‘ngemplang\u27. Di sisi lain penyerapan tenaga kerja dan efek turunan dari bisnis UKM kiranya akan menggerakkan roda ekonomi di lokal. Apalagi saat ini gerusan terhadap daya tahan ekonomi kita terutama terhadap Industri Manufakturing Kecil dan Menengah – IMKM, yang menghadapi gempuran barang‐barang Cina yang membanjiri pasar Indonesia karena pelaksanaan ASEAN‐CHINA Free Trade Area sungguh menarik untuk disimak. Hanya dengan penelitian ke lapangan maka akan dapat diperoleh informasi yang berharga.Pemahaman yang seksama terhadap profil kinerja keunggulan bersaing IMKM melalui riset akan sangat bermanfaat terutama bagi landasan pengembangan menghadapi globalisasi. Hanya dengan melakukan riset‐riset yang nyata maka pengembangan dan kontribusi terhadap dunia IMKM akan benar‐benar nyata dan bermanfaat.Adapun 3 (tiga) profil utama yang perlu mendapat perhatian (masih lemah/kurang) dariindustri manufaktur kecil dan menengah di Kota Bandung dapat disusun sebagai berikut:1. kategori 1 mempunyai profil sebagai berikut :a. pembelian barang‐barang dari Perusahaan Bapa/Ibu tidak dilakukan secara tunai/tidak dibayar saat itu (=mundur sekian bulan)b. Biaya untuk membuat barang dan biaya lainnya dalam USAha ini terasa berat saat inic. suplai/pasokan bahan baku untuk pembuatan barang selama ini lancard. Bapa/Ibu suka melakukan inovasi (pembaharuan) terhadap barang yang dihasilkan (bentuknya, atau lainnya)2. kategori 2 mempunyai profil sebagai berikut :a. Kekurangan modal merupakan kesulitan utama dalam menjamin supaya USAha Bapa/Ibu tetap berjalanb. Apabila ada lonjakan peningkatan pembelian terhadap barang Bapa/Ibu (lagi rame) maka untuk menambah pembuatan barang selalu terjadi kekurangan modalc. Modal yang sekarang digunakan untuk USAha sebagian besar ( lebih dari 50%) berasal dari pinjaman (bukan modal sendiri)3. Kategori 3 mempunyai profil sebagai berikut :a. Pembayaran bahan baku harus tunai/ lunas/cashb. Apabila Bahan baku yang sekarang digunakan untuk membuat barang dalam USAha Bapa/Ibu tidak ada maka akan ada pengganti nyac. Bahan baku pengganti sulit didapatd. Biaya pengiriman barang ditanggung oleh Bapa/Ib

New Reports of Exotic and Native Ambrosia and Bark Beetle Species (Coleoptera: Curculionidae: Scolytinae) From Ohio

In a 2007 survey of ambrosia and bark beetles (Coleoptera: Curculionidae: Scolytinae) along a transect in northeastern Ohio, we collected six exotic and three native species not previously reported from the state. These species include the exotic ambrosia beetles Ambrosiodmus rubricollis (Eichhoff), Dryoxylon onoharaensum (Murayama), Euwallacea validus (Eichhoff), Xyleborus californicus Wood, Xyleborus pelliculosusEichhoff, and Xylosandrus crassiusculus (Motschulsky). The native ambrosia beetle Corthylus columbianus Hopkins, and the native bark beetles Dryocoetes autographus (Ratzeburg) and Hylastes tenuis Eichhoff are also reported from Ohio for the first time. Our study suggests a northward range expansion for five of the six exotic species including, X. crassiusculus, which is an important pest of nursery and orchard crops in the southeastern United States
