Traces and shards of self-injury: Strange accounting with “Author X”
No full textIn this strange account autoethnography, three or four authors explore their lived experiences with self-injury. Strange accounting is both a post-modern style of text, and a method for keeping identities concealed when risks and secrets are in play. Author X, a post-modern place-keeper for an anonymous author who may or may not have contributed to this manuscript, introduces a new dimension and layer of concealment. With Author X in-play and under erasure, the reader will never be sure if there were three or four authors on this manuscript. Through strange accounting, a post-structuralist/postmodernist frame will be applied to understanding the self-injury experience. We frame self-injury as a social practice and, for some, an everyday norm, while remaining acutely aware of the stigma surrounding the topic of self-injury. Each of us, coupled with Author X, provide the others cover to trace stories of self-injury through the literature, our flesh, and our lives

Solvent- and vapor-induced isomerization between the luminescent solids [CuI(4-pic)](4) and [CuI(4-pic)](infinity) (pic = methylpyridine). The structural basis for the observed luminescence vapochromism
No full textExposure of the polymeric solid [CuI(4-pic)](infinity) (pic = picoline = methyl pyridine) to liquid or vapor toluene leads to disappearance of its room-temperature blue emission (lambda (max) 437 nm) and the appearance of a yellow emission (lambda (max) 580 nm) characteristic of the [CuI(4-pic)](4) tetramer. The process is reversed when the latter is exposed to liquid or vapor n-pentane. Analogous transformations between the tetrameric and polymeric forms do not occur when the 3-picoline analogues [CuI(3-pic)](x) are similarly treated. Single-crystal X-ray diffraction studies on the compounds [CuIL](infinity) and [CuIL](4) (L = 3-, 4-pic) indicate that the 4-pic tetranuclear isomer incorporates toluene into its solid phase to give a material with the composition [CuI(4-pic)](4). 2C(6)H(5)CH(3), but the other three phases are solvent-free. The chains in the two polymeric phases exhibit double-zigzag configurations, also commonly observed in zeolitic tetrahedral structures. In both polymeric phases, the chains propagate along the monoclinic b axis. The 3-pic tetrameric phase can be described as a close-packed structure of [CuIL](4) units, whereas tetramers in the 4-pic phase form infinite columns along the unique tetragonal c axis segregated by four columns of toluene pairs. These structural differences explain the different behaviors during the phase transformation between tetrameric and polymeric polymorphs of the 3-pic and 4-pic compounds

No full textPENGARUH IRADIASI SINAR-γ PADA BAHAN KONDUKTOR IONIK PADAT (CuI)x(Na3PO4)1-x (x = 0,1 dan x = 0,3). Pengaruh radiasi sinar-γ terhadap bahan konduktor ionik padat (CuI)x(Na3PO4)1-x telah dipelajari. Bahan konduktor ionik padat (CuI)x(Na3PO4)1-x (x = 0.1 dan x = 0.3) telah dapat dibuat dengan mencampurkan bahan CuI dan Na3PO4 dengan perbandingan fraksi berat tertentu, ditekan pada tekanan 48,26 x 106 N/m2 menjadi pelet dengan diameter 1,5 x 10-2 m. Bahan konduktor ionik padat tersebut di radiasi sinar-γ dengan dosis 5 kGy hingga 30 kGy. Analisis puncak-puncak difraksi sinar-X pada bahan konduktor ionik padat (CuI)x(Na3PO4)1-x menunjukkan struktur CuI dan Na3PO4. Regangan kisi kristal (CuI)x(Na3PO4)1-x stabil terhadap pengaruh dosis radiasi.

A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Exploring the apparent properties and Q-markers for quality control of Cornus officinalis
No full textCornus officinalis Siebold & Zucc. has a high nutritious value and is widely used in food fields. To distinguish the quality of cornus in different areas, this research provided a new strategy for comprehensively evaluating cornus. As a result, 12 iridoid glycosides and 7 polyphenols were identified and quantified by UHPLC-Q-TOF/MS in 13 batches of samples from five different origins. Chromaticity analysis pointed out that pelargonidin-3-O-galactoside, total iridoids, and total polyphenols performed high relation with 1365*. Antioxidant activity and inhibition of α-glucosidase effect correlated with the chemical analysis suggested that iridoid glycosides and
polyphenols should represent bioactivity of total extracts. Among these compounds, loganic acid, 7-ketologanin, cornuside I, and pelargonidin-3-O-glucoside were regarded as quality markers of cornus, which displayed the highest correlation with appearance. Above all, this paper contributed to establishing standards of external character and internal components for quality control of cornus
