    1. Oh! mother dear I sigh in vain, To live my childhood o\u27er again ... And see thy clear, love beaming eye ... Outshine the stars up in the sky, Oh mother dear bright sunny rays, That give such joy and heav\u27nly bliss, As by thy knee I used to pray, Or climb\u27d to steal affection\u27s kiss. CHORUS: Oh mother dear I sigh in vain To live my childhood o\u27er again, And see thy clear love beaming eye, Outshine the stars up in the sky. Oh! mother dear, Oh! my mother dear. 2. Oh! mother dear, those early scenes, The flow\u27ry fields, and meadows green, As thoughts come back I heave a sigh, And wish for happy days gone by; Long since I left my native shore, But now my heart beats just as then, Tho\u27 miles of sea between us roar, Dear mother I\u27ll come again

    Thermal OH (1667/65 MHz) Absorption and Nonthermal OH (1720 MHz) Emission Towards the W28 Supernova Remnant

    The W28 supernova remnant is an excellent prototype for observing shocked gas resulting from the interaction of supernova remnants (SNRs) and adjacent molecular clouds (MCs). We present two new signatures of shocked molecular gas in this remnant. One is the detection of main-line extended OH (1667 MHz) absorption with broad linewidths. The column density of OH estimated from the optical depth profiles is consistent with a theoretical model in which OH is formed behind a C-type shock front. The second is the detection of extended, weak OH (1720 MHz) line emission with narrow linewidth distributed throughout the shocked region of W28. These give observational support to the idea that compact maser sources delineate the brightest component of a much larger region of main line OH absorption and nonthermal OH (1720 MHz) emission tracing the global structure of shocked molecular gas. Main line OH (1665/67) absorption and extended OH (1720 MHz) emission line studies can serve as powerful tools to detect SNR-MC interaction even when bright OH (1720 MHz) masers are absent.Comment: 14 pages, 3 figures, one table, to appear in ApJ (Jan 10, 2003

    This study was carried out to see the effect of modified atmosphere storage on the storage life of Southport White Globe (SWG) onions. SWG onions were packed in polyethylene bags and stored at 20°C for 14 weeks. To increase its effectiveness, phorone, KMnO4 and Ca(OH)2 at various levels were also placed inside the polyethylene bags. Production of CO2, 02 and ethylene were monitored fortnightly, and at the end of storage, onion sprouting, rotting, and rooting were also observed. The results show that phorone at 2 ml tended to stimulate CO2 production, while KMn04, Ca(OH)2, KMnO4 plus Ca(OH)2 at either 200 g or 400 g inhibited CO2 production, however, ethylene elimination tended to stable. No root growths were detected. Disease incidents were also prohibited by KMnO4, Ca(OH)2, and KMnO4 plus Ca(OH)2 at 400 g. On the other hand, those chemicals stimulated onion sprouting.

    Hello!! Since the last time I posted a lot has happened and so far, still good. That’s not to say I haven’t needed help on a few Reference Questions but things are going pretty well. I’ve had a few ‘RefWins’ where I’ve felt that I was particularly helpful, one was even over chat! Everything is going great thus far and I’m definitely learning, a lot. [excerpt

    A lot has been going on in Special Collections since my last blog post, so I’ll get you up to speed. As mentioned in my first post, I and the other interns created our own book. It was an awesome project and I learned to appreciate books as physical masterpieces and not just the words inside. I made my book with a black cover, and the end pages were made from homemade paper.

    PILLARIZATIONOF LAYERED TETRATITANATES ANION BYZIRCONIUM(IV) POLYCATION SPECIES Pilarisasi Layer Anion Tetratitanat o/eh Spesies Polikation Zirkonium(lV)

    ABSTRACT Pilfaring layered tetratitanates anion by zirkonium(lV) polycation species has been realized by three steps: 1). cationexchange of potasium tetratitanates, 2). intercalation of n-butylamine compound in layered hydrogen tetratitanates and 3). intercalation of zirconium(IV) polycation species by mixing butylamine-intercalated tetratitanates with an aqueous solution of ZrOC12.8H20at pH various: 0.1, 0.9 and 1.8. The procedure was carried out by Chimie Douce method. The structures oftitanates and the products which had undergone ft exchange and intercalated by n-butylamine and zirkonium(IV) polycation spesies were investigated by.X-rays Diffractometer(XRD) and X-rays Fluorescence (XRF). It was found in the research that [Zr(H20)ef+, [Zr(OH)(H20M3+or [Zr(OHMH20)B!+types have presented in the [nterlayerof the products. At pH = 0.1 and 0.9, [Zr(OH)(H20hf.+ type was pillared more dominated in layered tetratitanates than [Zr(H20)ef+ type. At pH 1.8, it was signaled that [Zr(OH)(H20)r+ and [Zr(OHMH20)B!+ types intercalated in layered tetratitanates. Keywords: tetratitanates, intercalation, zirconium(IV) species, Chimie Douc

    Further detections of OH masers in carbon stars with silicate features

    A sample of J-type carbon stars was searched for OH maser emission. The new detection of three OH lines towards two silicate carbon stars is reported. In V778 Cyg, previously known as the main-lines (1665 and 1667 MHz) maser source, the satellite 1612 MHz emission was discovered while in NSV 2814 the main OH lines were detected. The presence of OH maser lines confirms the former suggestion that oxygen-rich material is located in the vicinity (≈\approx 1015−1610^{15-16} cm) of silicate carbon stars.Comment: LaTeX2e, 4 pages with 2 figure
