Hypocotyl formation during the epigeal germination of seedlings is under strict hormonal regulation. In a 3 d old Zinnia elegans seedling system, gibberellic acid （GA3） exerts an opposite effect to that exerted by light on hypocotyl photomorphogenesis because GAz promotes an etiolated-like growth with an inhibition of radial （secondary） growth. For this reason, the effect of GA3 on the basic peroxidase isoenzyme from Z. elegans （ZePrx）, an enzyme involved in hypocotyl lignin biosynthesis, was studied. The results showed that GA3 reduces ZePrx activity, similarly to the way in which it reduces seedling secondary growth. This hormonal response is supported by the analysis of the ZePrx promoter, which contains four types of GA3-responsive ***： the W Box/O2s; the Pyr Box; the GArE; and the Amy Box. Taken together, these results suggest that ZePrx is directly regulated by GA3, with this effect matching the inhibitory effect of GA on the hypocotyl secondary growth.

作者： v. rajmohan O. Uma Maheswari Department of Electronics and Communication Engineering College of Engineering Chennai India

In today’s digital era, developing digital circuits is bounded by the research towards investigating various nano devices. This paper provides the design of compact Baugh-Wooley multiplier using reversible logic. Even though various researches have been done for designing reversible multiplier, this work is the first in the literature to use Baugh-Wooley algorithm using reversible logic. In this work, a new 5 × 5 reversible multiplier cell is proposed which will be useful in designing Baugh-Wooley multiplier. The proposed single multiplier cell is able to perform addition of a 1 × 1 product with the sum and carry from the previous cell. This reversible multiplier cell is useful in building up regularity in the array multipliers. The Toffoli gate synthesis of the proposed reversible multiplier cell is also given.

Nivicolous myxomycete assemblages were surveyed on the northwest of the Greater Caucasian ridge in May-June 2010 and 2011 at a north facing transect between 1,700 and 2,920 m elevation of the summit Malaya Khatipara situated within the Teberda state Biosphere *** characters of 396 collections representing 45 taxa(39 species,3 varieties,and 3 forms)of myxomycetes in 8 genera and 5 families were ***(13)taxa are classified as rare(a species representsrecords).Only seven species were found to be widely distributed(present in 50%or more of the 17 studied localities).To confirm the assignment of specimens to morphospecies,we obtained independently from determination 145 partial sequences of the 18s ssU rrNA gene from 35 taxa of Lamproderma,Meriderma,Physarum and Diderma,which turned out to represent 58 *** of the taxa represented by more than one sequence had several genotypes,with an average of 1.7 genotypes per *** for three taxonomically difficult groups of species,partial ssU sequences did well correspond with the respective morphospecies and where similar or identical to sequences of specimens from the European Alps,making this marker a good candidate for barcoding in *** richness and diversity increased from subalpine crooked-stem birch forests(23 species,2 varieties,H′02.8,E00.88,D00.08)to alpine dwarf shrub communities(34 species and 2 varieties,2 forms,H′03.2,E00.89,D00.05)but decreased again for alpine meadows(27 species and 2 varieties,2 forms,H′03.1,E00.91,D00.06).species richness and alpha-diversity reached maximum values for ground litter,whereas leaves and stems of living shrubs above ground harboured a more depauperate myxomycete assemblage.

v style="text-align:justify;"> We know that functional and structural organization is altered in human brain network due to Alzheimer’s disease. In this paper we highlight how Graph Theory techniques, its structural parameters like connectivity, diameter, vertex centrality, betweenness centrality, clustering coefficient, degree distribution, cluster analysis and graph cores are involved to analyse magnetoencephalography data to explore functional network integrity in Alzheimer’s disease affected patients. We also record that both weighted and unweighted undirected/directed graphs depending on functional connectivity analysis with attention to connectivity of the network and vertex centrality, could model and provide explanation to loss of links, status of the hub in the region of parietal, derailed synchronization in network and centrality loss at the vital left temporal region that is clinically significant were found in cases carrying Alzheimer’s disease. We also notice that graph theory driven measures such as characteristic path length and clustering coefficient could be used to study and report a sudden electroencephalography effect in Alzheimer’s disease through entropy of the cross-sample. We also provide adequate literature survey to demonstrate the latest and advanced graphical tools for both graph layouts and graph visualization to understand the complex brain networks and to unravel the mysteries of Alzheimer’s disease. v>

Epidermolysis Bullosa (EB) is a group of rare genetic skin conditions, which is characterised by extremely fragile skin and recurrent blister formation, resulting from minor mechanical friction or trauma. sufferers of EB have compared the sores to third-degree burns. stevens-Johnson syndrome is a rare but very serious skin problem, which causes the appearance of reddish lesions throughout the body and other changes, such as difficulty in breathing and fever, which can endanger the life of the affected person. The aim of this study was to show efficacy of a NANOsKIN ACT, AND NANOsKIN ACT sOFT wound dressing on the wound care management in patients with EB AND stevens-Johnson syndrome (sJs).

Evolution of periodic orbits in sun-Mars and sun-Earth systems are analyzed using Poincare surface of section technique and the effects of oblateness of smaller primary on these orbits are considered. It is observed that oblateness of smaller primary has substantial effect on period, orbit’s shape, size and their position in the phase space. since these orbits can be used for the design of low energy transfer trajectories, so perturbations due to planetary oblateness has to be understood and should be taken care of during trajectory design. In this paper, detailed stability analysis of periodic orbit having three loops is given for Asub>2sub> = 0.0001.

随着航空航天高分辨率观测手段的逐步成熟,定量遥感在有效解决了光学地表多尺度效应后,更高分辨率的光学偏振效应在地表、大气、仪器3大要素方面逐步全面凸显出来,并直接决定或影响高分辨率观测系统的定量遥感效能实现和质量保障。例如,植被冠层极其微弱的多次散射反射偏振效应,如果不加扣除其模型误差达到136%;大气衰减本质是大气偏振效应,是遥感反演的最大误差源,误差达到5%—30%,偏振手段扣除大气误差目前已可以降低一半以上的误差;观测仪器扣除多次散射透射偏振光后,可以实现5 nm分辨率下0.1—0.3 nm高光谱定标能力,并借助偏振强化光噪声分离出中心波长偏移和带宽退化的误差根源。借助偏振"强光弱化,弱光强化",能够实现稳定度达10^(-8)月球辐亮度基准观测,为遥感辐亮度定标不确定度由7%到1%—2%跨越提供可能。
