261   Grafting vinyl monomers onto wool fibers. VIII. Graft copolymerization of methyl methacrylate onto wool using peroxydiphosphate–fructose redox system Grafting vinyl monomers onto wool fibers. VIII. Graft copolymerization of methyl methacrylate onto wool using peroxydiphosphate–fructose redox system Sachchidanand Srivastava and Prof. Namdeo S. Gajbhiye    2003 The graft copolymerization of methyl methacrylate onto wool fibers was investigated in aqueous solution using the peroxydiphosphate–fructose redox system. The rate of grafting was determined by varying monomer, acidity of the medium, temperature, nature of wool, and reaction medium. The graft yield increases with increase in peroxydiphosphate concentration. With increase in concentration of fructose up to 7.5 × 10−4 mole/l., there is a significant increase in graft yield; and w... 查看全文

262   Structured intraoperative assessment of pancreatic gland characteristics in predicting complications after pancreaticoduodenectomy Structured intraoperative assessment of pancreatic gland characteristics in predicting complications after pancreaticoduodenectomy Y. K. KIM, J. H. CHIN, S. J. KANG, I. G. JUN, J. G. SONG, S. M. JEONG, J. Y. PARK and G. S. HWANG    2012 The morbidity rate after pancreaticoduodenectomy remains high (20–50 per cent) and postoperative pancreatic fistula (POPF) is a major underlying factor. POPF has been reported to be associated with pancreatic consistency (PC) and pancreatic duct diameter (PDD). The aim was to quantify the risk of pancreaticojejunostomy-associated morbidity (PJAM) by means of a structured intraoperative assessment of both characteristics. 查看全文

263   XMM-Newton observations of the Mouse, SLX 1744-299 and SLX 1744-300 XMM-Newton observations of the Mouse, SLX 1744-299 and SLX 1744-300    2005 We observed the radio and X-ray source G359.23-0.82, also known as "the Mouse", with XMM-Newton. The X-ray image of this object shows a point-like source at the Mouse's "head", accompanied by a "tail" that extends for about 40″ westward.

265   Exploring high energy activities in the Superbubble N44 with XMM-Newton Exploring high energy activities in the Superbubble N44 with XMM-Newton    2006 We report the results of the XMM-Newton Observation of N44, one of the brightest Superbubble (SB) in X-rays in the Large Magellanic Cloud. There is a significant X-ray emission inside the main shell, blowout regions, and supernova. We discovered the spatial structure of inner hot gas; The inner hot gas consists of high temperature (∼1.8 keV) and low temperature (∼0.6 keV) components. This value is exceedingly high compared with other SBs. Because the former shows significantly lower ioni... 查看全文

271   Deep XMM-Newton observation of a northern LMC field. I. Selected X-ray sources Deep XMM-Newton observation of a northern LMC field. I. Selected X-ray sources    2003 First results from a deep XMM-Newton observation of a field in the Large Magellanic Cloud (LMC) near the northern rim of the supergiant shell LMC 4 are presented. Spectral and temporal analyses of a sample of selected X-ray sources yielded two new candidates for supernova remnants, a supersoft X-ray source and a likely high mass X-ray binary (HMXB) pulsar. From the fourteen brightest sources ten exhibit power-law X-ray spectra with slopes compatible to those of active galactic nuclei (AGN) in th... 查看全文

272   Is Vela Jr. a young supernova remnant? Is Vela Jr. a young supernova remnant?    2009 The supernova remnant RX J0852.0-4622 (or Vela Jr.) has been considered to be very young (∼680 yr) based mainly on the possible detection of a radioactive decay line of 44Ti whose lifetime is only ∼90 yr. Here, we report on expansion measurements of the northwestern rim of this remnant, based on XMM-Newton observations separated by 6.5 yr. The expansion rate is derived to be 0.026 ± 0.05 ± 0.09 % yr- 1 (the first and second-term errors are responsible for statistical and sy... 查看全文

273   Effective area calibration of the reflection grating spectrometers of XMM-Newton I. X-ray spectroscopy of the Crab nebula Effective area calibration of the reflection grating spectrometers of XMM-Newton I. X-ray spectroscopy of the Crab nebula    2009 Context. The Crab nebula and pulsar have been widely used as a calibration source for X-ray instruments. The in-flight effective area calibration of the Reflection Grating Spectrometers (RGS) of XMM-Newton depend upon the availability of reliable calibration sources. Aims. We investigate how the absolute effective area calibration of RGS can be obtained using Crab as a standard candle. Methods. We have analysed RGS observations of the Crab using different instrument configurations and spatial of... 查看全文

We choose two radial bins, 1′-3′ and 8′-16′ (8′-14′ for EMOS; hereafter the central and the outer zones), where the temperature is almost constant, to carry out the detailed abundance measurements of O, Ne, Mg, Si, S, Ar, Ca, Fe and Ni using EPIC-PN (EPN) and -MOS (EMOS) data.

275   An XMM-Newton view of the cluster of galaxies Abell 85 An XMM-Newton view of the cluster of galaxies Abell 85    2005 We have observed the cluster of galaxies Abell 85 with XMM-Newton. These data have allowed us in a previous paper to confirm the existence of the extended 4 Mpc filament detected by the ROSAT PSPC in the neighbourhood of this cluster, and to determine an X-ray temperature of about ∼2keV. We now present a thorough analysis of the properties of the X-ray gas in the cluster itself, including temperature and metallicity maps for the entire cluster. These results show that Abell 85 had intense me... 查看全文

EPIC hardness ratios and optical and radio information are used to distinguish between different source classes. The survey detects 856 sources in an area of 1.24 square degrees. We correlate our sources with earlier M 31 X-ray catalogues and use information from ... 查看全文

278   XMM-Newton study of hard X-ray sources in IC 443 XMM-Newton study of hard X-ray sources in IC 443    2003 We present XMM-Newton observations of hard X-ray emission from the field of IC 443, a supernova remnant interacting with a molecular cloud. The hard emission from the field is dominated by 12 isolated sources having 2-10 keV flux ≳10-14 erg cm-2 s-1. Only a fraction of the sources are expected to be extragalactic or stars on statistical grounds, while the others may be associated with the remnant. We have analyzed near-infrared K band and also DSS optical data for all of the detected source... 查看全文

As shown from previous X-ray observations, NGC 253 shows a mixture of extended (disk and halo) and point-source emission. The high XMM-Newton throughput allows a detailed investigation of the spatial, spectral and variability properties of these components simultaneously. We characterize the brightest sources by their hardness ratios, detect a bright X-ray transient [similar to] 70 double prime SSW of the nucleus, and... 查看全文

We have identified X-ray SNRs by comparing the list of Chandra X-ray sources in M33 with tabulations of SNR candidates identified from (1) elevated [S II]/Halpha ratios in the optical, and (2) radio spectral indices. Of the 98 optically known SNRs in M33, 22 have been detected at > 3σ level in the soft band (0.35-1.1 keV). At least four of these SNR candidates are spatially extended. We have ... 查看全文

From a comparison of the two XMM-Newton observations we obtain more accurate values for the X-ray luminosity and colours of the source five days after the event, and a limit on its decline rate.

Investigations carried out using microalgae alone in the culture system for the initial feeding of the silver pomfret larvae showed that Chlorella, Isochrysis and Nannochloropsis without rotifers are not conducive to the survival of newly hatched larvae.
