Cluster radioactivity in superheavy nuclei 299-306122
Cluster radioactivity is an intermediate between alpha decay and spontaneous fission. It is also an exotic decay obtained in superheavy nuclei. When a cluster decay is detected in superheavy nuclei, the daughter nuclei is having near or equal to doubly magic nuclei. We have investigated cluster decay of isotopes of He, Li, Be, Ne, N, Mg, Si, P, S, Cl, Ar and Ca in the superhaevy nuclei region 299-306122. We have also compared the logarithmic half-lives of cluster decay with that of other models such as Univ [1], NRDX [2], UDL [3] and Horoi [4]. From this study it is concluded that cluster decay of 4He, 22Ne, 26Mg, 28Si 30Si, 34S, 40Ca and 46Ca are having shorter logarithmic half-lives compared to exotic cluster decay modes
Systematics of proton decay of actinides
255-262The phenomenon of proton emission from nuclear ground states limits the possibilities of the creation of more exotic proton rich nuclei that are usually produced by fusion-evaporation nuclear reactions. In the energy domain of radioactivity, proton can be considered as a point charge having highest probability of being present in the parent nucleus. Conclaves et al.1 studied the two-proton radioactivity of nuclei of mass number Aet al.2 reviewed the theories of proton emission to analyse the properties of nuclear matter. Maglione et al.3 analysed the proton emission from the some deformed nuclei. We have studied proton decay in almost all actinide nuclei. We have calculated the energy released during the proton decay (QP), penetration factor (P), and half-lives of proton decay. Proton decay half-lives are also longer than that of other decay modes such as alpha decay and spontaneous fission. To check the Geiger-Nuttal law for proton decay in actinide nuclei, we have plotted the logarithmic proton decay half-lives versus 1/sqrt(Q). The competition of proton decay with different decay modes such as alpha decay and spontaneous fission are also studied. We have also highlighted possible proton emitters with the corresponding energies and half-lives in the actinide region
Transcriptional profiling of pea ABR17 mediated changes in gene expression in Arabidopsis thaliana
<p>Abstract</p> <p>Background</p> <p>Pathogenesis-related proteins belonging to group 10 (PR10) are elevated in response to biotic and abiotic stresses in plants. Previously, we have shown a drastic salinity-induced increase in the levels of ABR17, a member of the PR10 family, in pea. Furthermore, we have also demonstrated that the constitutive expression of pea <it>ABR17 </it>cDNA in <it>Arabidopsis thaliana </it>and <it>Brassica napus </it>enhances their germination and early seedling growth under stress. Although it has been reported that several members of the PR10 family including ABR17 possess RNase activity, the exact mechanism by which the aforementioned characteristics are conferred by ABR17 is unknown at this time. We hypothesized that a study of differences in transcriptome between wild type (WT) and <it>ABR17 </it>transgenic <it>A. thaliana </it>may shed light on this process.</p> <p>Results</p> <p>The molecular changes brought about by the expression of pea <it>ABR17 </it>cDNA in <it>A. thaliana </it>in the presence or absence of salt stress were investigated using microarrays consisting of 70-mer oligonucleotide probes representing 23,686 <it>Arabidopsis </it>genes. Statistical analysis identified number of genes which were over represented among up- or down-regulated transcripts in the transgenic line. Our results highlight the important roles of many abscisic acid (ABA) and cytokinin (CK) responsive genes in <it>ABR17 </it>transgenic lines. Although the transcriptional changes followed a general salt response theme in both WT and transgenic seedlings under salt stress, many genes exhibited differential expression patterns when the transgenic and WT lines were compared. These genes include plant defensins, heat shock proteins, other defense related genes, and several transcriptional factors. Our microarray results for selected genes were validated using quantitative real-time PCR.</p> <p>Conclusion</p> <p>Transcriptional analysis in <it>ABR17 </it>transgenic <it>Arabidopsis </it>plants, both under normal and saline conditions, revealed significant changes in abundance of transcripts for many stress responsive genes, as well as those related to plant growth and development. Our results also suggest that <it>ABR17 </it>may mediate stress tolerance through the modulation of many ABA- and CK-responsive genes and may further our understanding of the role of ABR17 in mediating plant stress responses.</p
Modeling Stellar CaII H & K Emission Variations: Spot Contribution to the S-index
The S-index is a measure of emission in the CaII H & K lines and is a widely
used proxy of stellar magnetic activity. It has been assumed until now that the
S-index is mainly affected by bright plage regions in the chromosphere. In
particular, the effect of starspots on the S-index has been neglected. In this
study we revisit this assumption. For this we analyze high-resolution
observations of sunspots recorded in the CaII H spectral line at the Swedish
1-m Solar Telescope and determine the contrast of spots with respect to the
quiet surroundings. We find that the CaII H line core averaged over whole
sunspots (including superpenumbrae) is brighter than in the quiet surroundings
and that the spot contrast in the line core is comparable to the facular
contrast. This allows us to get a first estimate of the influence of spots on
the S-index. We show that spots increase the S-index. While this increase is
quite small for the Sun, it becomes significantly larger for more active stars.
Further, we show that the inclusion of the contribution of spots to the S-index
strongly affects the relationship between the S-index and stellar disk area
coverages by spots and faculae, and present the new relations.Comment: 11 pages, 5 figures, accepted for publication in ApJ Letter
Over expression of anti-apoptotic gene in banana cv Rasthali enhances resistance against Fusarium oxysporum f. sp. cubense Race 1
The most popular banana cv Rasthali was transformed with anti-apoptotic gene, AtBAG4 regulated with two different promoters viz., ZmBgl and ubiquitin to enhance the tolerance levels to Fusarium oxysporum f. sp. cubense Race 1 (FOC1). The differences in gene expression driven by two promoters revealed that stronger expression of AtBAG4 gene under the ubiquitin promoter suppressed the infection and spreading processes of FOC1 in transgenic banana under standard bioassay systems. Analysis using the real time PCR showed the varying levels of AtBAG4 gene expression under two promoters. It was evident that ZmBgl driven AtBAG4 lead to lower gene expression in leaves which correlated with lesser levels of resistance to FOC1. Constitutive expression of AtBAG4 under the control of ubiquitin promoter showed increased transgene transcripts which directly correlated with the enhanced tolerance against FOC1 from seedlings stage to active vegetative phases. This study reveals the importance of constitutive expression of anti-apoptotic gene showing enhanced tolerance against the most dreaded FOC1 in highly susceptible variety Rasthali
Cluster radioactivity in superheavy nuclei 299-302120
The cluster radioactivity is an unusual decay process observed in superheavy nuclei. When a cluster nuclei are emitted, the residual or daughter nuclei is having doubly magic nuclei or it may be neighbourhood of the same. We have studied cluster radioactivity [4He, 6Li, 9Be, 20,22Ne, 23N, 24-26Mg, 28-30Si, 31P, 32-34S, 35Cl, 36,38,40Ar, 40-46Ca ] in the superheavy nuclei 299-302120 using the nuclear and proximity model. The calculated cluster decay half-lives are compared with that of the other theoretical models such as Univ1, NRDX2, UDL3 and Horoi4. From the comparison of different models we have observed that the cluster nuclei with 4He, 9Be, 22Ne, 26Mg, 30Si, 34S, 40Ca and 46Ca are having smaller logarithmic half-lives than the exotic cluster decay modes
