Studi Perencanaan Industri Sari Buah Jambu Mete
No full textPengembangan jambu mete d i Indonesia dilaksanakan dalam rangka meningkatkan lapangan kerja dan pendapatan petani di lahan beriklim kering, peningkatan ekspor komoditi ja&u mete, s e r t a r e h a b i l i t a s i lahan k r i t i s melalui penghijauan dan konservasi tanah dan a i r d i daerah peka erosi. Oleh karena i t u perkembangan luas areal perkebunan jambu mete meningkat, rata-rata 6.59 % per tahun. Perluasan a r e a l perkebunan tersebut meningkatkan pula produksi jambu mete, rata-rata 6.60% per tahun. Walaupun demikian pemanfaatan h a s i l tanaman jambu mete hanya terbatas pada mete gelondongnya, sedangkan pemanfatan jambunya masih r e l a t i f sedikit bahkan dibuang sebagai limbah
Synthesis and photoluminescence properties of Dy3+ doped white light emitting CdTa2O6 phosphors
No full textThe undoped and CdTa2O6:Dy3+ (0.2 <= x <= 2.0 mol%) phosphors were synthesized at 1100 degrees C for 12 h by the conventional solid state reaction method. The synthesized CdTa2O6:Dy3+ phosphors were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS) and Photoluminescence (PL) analyses. The PL spectra showed the presence of excitation peaks between 310 and 440 nm due to the 4f-4f transitions of Dy3+. The emission of Dy3+ ions at 353.0 nm excitation was observed at 487.1 nm (blue) and 577.8 nm (yellow) due to the F-4(9/2)-> H-6(15/2) transitions and F-4(9/2)-> H-6(13/2) transitions, respectively. The PL analysis results also showed that the emissions increase with the increasing Dy3+ ion content. The emissions increased with the doping concentration of up to 1 mol%, and above this level decreased due to concentration quenching effect. The CIE chromaticity color coordinates (x,y) of the CdTa2O6:Dy3+ phosphors were found to be in the white light region of the chromaticity diagram. (C) 2015 Elsevier Inc. All rights reserved

Disulfide Mapping of Reduced MetE
No full text<div><p>Reduced MetE should be cleaved N-terminally to each of its seven cysteines to generate eight protein fragments as shown in the diagram, where peptide <i>A</i> comprises residues 2–322, <i>B</i> is itz323–352, <i>C</i> is itz353–515, <i>D</i> is itz516–559, <i>E</i> is itz560–642, <i>F</i> is itz645–725, and <i>G</i> is itz726–753. It is assumed that itz643–644 is too small to be resolved. β-elimination of cyanylated cysteines can also occur; <i>H</i> is itz516–642 with β-elimination at cysteine 560, and <i>I</i> is itz645–753 with β-elimination at cysteine 726.</p>
<p>(A) The HPLC trace at 280 nm for disulfide mapping of fragments derived from cyanylation and cleavage of reduced MetE. Following derivitization, the samples were chromatographed on a C4 reversed-phase column as described in the <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0020336#s4" target="_blank">Materials and Methods</a>. Peaks were assigned from comparison of masses determined by mass spectrometry and predicted masses (see <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0020336#pbio-0020336-t001" target="_blank">Table 1</a>).</p>

Leaching of F-type fly Ash Based Geopolymers
No full textAbstractGeopolymers are the synthetic analogues of natural zeolitic materials. Geopolymeric materials possess excellent mechanical properties, including fire and acid resistance. These properties make geopolymers an alternative construction material compared to Portland cement. Most waste materials such as fly ash, blast furnace slag and mine tailings contain sufficient amounts of reactive alumina and silica that can be used as source materials for in situ geopolymerisation reactions. Alkali-activation of aluminosilicate solids using alkaline hydroxide and/or silicate solutions can be used to synthesize inorganic geopolymeric binders or alkali-activated cements, displaying excellent physical and chemical properties. In this experimental study the effects of curing conditions on physical and mechanical properties and on the microstructure of geopolymer pastes were investigated. F class fly ash was activated by 12M sodium hydroxide and sodium silicate solutions. Geopolymer pastes were cured at 40¡C, 80¡C and 120¡C for 6, 15 and 24hours respectively. The samples were tested for compressive strength at the ages of 7, 28 and 90 days and the effect of aging was also investigated. After 28 days of curing, the samples were crushed and were extracted using leaching tests. USEPA TCLP (toxicity characteristic leaching procedure) method was applied for leaching tests. Inductively Coupled Plasma-Optical Emission Spectroscopy was used to determine the content of leach solution. For 28-days samples, microstructure of the samples were observed by X-ray diffractometry(XRD), Scanning Electron Microscope(SEM)/Energy Dispersive X-Ray(EDX) Spectrometer, and Fourier Transform Infrared Spectroscopy(FTIR) techniques. The results showed that the curing temperature and time are important parameters affecting the mechanical properties and microstructure of geopolymers

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Photoluminescence characterization and heat treatment effect on luminescence behavior of BaTa2O6:Dy3+ phosphor
No full textUndoped and Dy3+-doped barium tantalate phosphors were synthesized by the solid-state reaction method at 1425 degrees C. Also, 10mol% Dy3+-doped BaTa2O6 was sintered between 1150 and 1425 degrees C in order to determine temperature effect on structural and luminescence properties. Afterwards, they were characterized by XRD, SEM-EDS and photoluminescence (PL) analyses. PL spectra exhibited the excitation peaks between 300 and 440nm. Two typical emissions were observed at 486.2nm (blue) and 577.7nm (yellow) due to the (F9/2H15/2)-F-4-H-6 and (F9/2H13/2)-F-4-H-6 transitions, respectively. Emission intensities increased with increasing doping concentration of Dy3+ up to 10mol% and then decreased due to the concentration quenching effect. Moreover, depending on the increase in heat treatment temperature, the intensity of emission reached maximum at 1425 degrees C. The calculated CIE chromaticity coordinates of phosphors located in the white light region
