Sequential Analysis of Trans-SNARE Formation in Intracellular Membrane Fusion

SM proteins stabilize cis-SNARE complexes leading to a specific preferred topology for trans-SNARE formation

‘Writing Now’

This chapter considers the themes and forms that characterise women’s writing in the new millennium. Post-9/11, self-representation has become a particularly urgent task for Muslim writers such as Monica Ali and Leila Aboulela. A concern with refugees, asylum seekers, and modern forms of slavery becomes increasingly prominent, not only in fiction – for example, Fadia Faqir’s My Name is Salma (2007) and Monica Ali’s In the Kitchen (2009) – but also in the theatre: Kay Adshead’s The Bogus Woman (2000), Sonja Linden’s Crocodile Seeking Refuge (2005), Christine Bacon’s Rendition Monologues (2008), Rukhsana Ahmad and Oladipo Agboluaje’s Footprints in the Sand (2008), Natasha Walter's Motherland (2008), and Gbemisola Ikumelo’s Next Door (2010). The impact of global capitalism, consumerism, and branding are explored in novels such as Scarlett Thomas’ Popco (2004), Ali Smith’s Girl Meets Boy (2007), and Winterson’s The Stone Gods (2007). Ageing is another major theme. Long a pre-occupation of Doris Lessing, it features also in Liz Jensen’s War Crimes for the Home (2002) and Alison Fell’s Tricks of the Light (2003). Anxieties about climate change and environmental apocalypse are addressed through dystopia in Maggie Gee’s The Ice People (1998) and The Flood (2004), Jeanette Winterson’s The Stone Gods (2007), Sarah Hall’s The Carhullen Army (2007), and Liz Jensen’s The Rapture (2009). Following Suniti Namjoshi’s pioneeringly collaborative Building Babel (1996), the use of multimedia in Maya Chowdhry’s digital poetry, Kate Pullinger’s ‘networked’ wikinovel Flight Paths (2005-), and the ‘visual novel’ (an interactive fiction game), gives literature an entirely new shape

Resonance spectroscopy of <SUP>30</SUP>Si nucleus in the excitation energy range 14.27 to 15.02 MeV

Absolute differential cross sections for the elastic scattering of a particles from 26Mg have been measured as a function of bombarding energy between 4.18 and 5.14 MeV at angles corresponding to the c.m. angles 90&#176;, 125&#176;, 141&#176;, and 167&#176;. The data have been analyzed using the multilevel multichannel expression of R matrix theory modified to replace the background hard sphere phase shifts by complex optical model phase shifts. These phase shifts have been obtained by fitting the averaged cross section with the optical model. This modification has resulted in reasonably good fits to excitation functions both in magnitude and shape. Twelve levels in the compound nucleus 30Si have been identified and their spins, parities, and widths have been determined. The possibility of the 0+ levels being fragmented components of a quartet parent state has been discussed

Spectroscopy of <SUP>50</SUP>V with (p, n&#947;) reaction

Information on the low-lying levels up to ~1.9 MeV excitation of the doubly odd nucleus50V has been obtained through the Ge (Li)-Ge (Li) coincidence study with the 50Ti(p, n &#947;)50V reaction. Branching ratios have been measured and tentative spin-parity assignments have been made. A detailed comparison with other measurements reported recently has also been made. Using the lowest seniority wave functions with (f7/2)p3 (f7/2)n-1 configuration, energy levels and electromagnetic properties have been calculated. These have been compared with the present and earlier experimental data

Total (p, n) reaction cross-section measurements on <SUP>50</SUP>Ti, <SUP>54</SUP>Cr, and <SUP>59</SUP>Co

The total (p, n) reaction cross sections, integrated over the 4&#928; solid angle and summed over all neutron groups, for 50Ti, 54Cr, and 59Co have been measured as a function of proton energy in the energy range 3.0-4.9, 2.2-5.2, and 2.0-5.1 MeV in 5 keV steps, respectively. No strong isobaric analog resonances were seen in the data. The fluctuations in the excitation functions were analyzed to extract &lt;&#915;&gt;av values using the "counting of maxima" method. The excitation functions, averaged over 100 keV energy interval reveal prominent intermediate width structures in the case of 50Ti. All the three excitation functions were averaged over suitable energy intervals and compared with the total reaction cross sections calculated utilizing the optical model. The data on 59Co and 54Cr agreed, while the data on 50Ti indicated a marked discrepancy with these optical model calculations. In the latter case, detailed Hauser-Feshbach (HF) and Hauser-Feshbach-Moldauer (HFM) calculations were carried out. The HFM calculations fit the data quite well. The importance of &#963;(p, n) measurements in determining the imaginary potential of the optical model at sub-Coulomb energies has been indicated

Stereospecific Total Synthesis of the Indole Alkaloid Ervincidine. Establishment of the C‑6 Hydroxyl Stereochemistry

The total synthesis of the indole alkaloid ervincidine (<b>3</b>) is reported. This research provides a general entry into C-6 hydroxy-substituted indole alkaloids with either an α or a β configuration. This study corrects the errors in Glasby’s book (Glasby, J. S. Encyclopedia of the Alkaloids; Plenum Press: New York, 1975) and Lounasmaa et al.’s review (Lounasmaa, M.; Hanhinen, P.; Westersund, M. In The Alkaloids; Cordell, G. A., Ed.; Academic Press: San Diego, CA, 1999; Vol. 52, pp 103–195) as well as clarifies the work of Yunusov et al. (Malikov, V. M.; Sharipov, M. R.; Yunusov, S. Yu. Khim. Prir. Soedin. 1972, 8, 760−761. Rakhimov, D. A.; Sharipov, M. R.; Aripov, Kh. N.; Malikov, V. M.; Shakirov, T. T.; Yunusov, S. Yu. Khim. Prir. Soedin. 1970, 6, 724–725). It establishes the correct absolute configuration of the C-6 hydroxyl function in ervincidine. This serves as a structure proof and corrects the misassigned structure reported in the literature
