Identifying groups with opposite stances using link-based categorizationLiao, Tsung-Ming 15 July 2005 (has links)
This thesis proposes a link-based approach to identify supporting and opposing groups in a Weblog community. We formulate the interaction behavior as a graph. Bloggers involved in the discussion of one specific issue are formulated as vertices. Semantic orientation is used to construct possible opposite opinion links. Bloggers with opposite stances will form an opposite link. A max-cut algorithm is used latter to obtain the optimal approximation of supporting and opposing groups. The categorization results are compared between semantic orientation classifier and simple link-based categorization. The simple link-based categorization compares then with the enhancement of link-based categorization using hypergraph.

Effect of copper on peroxidase isozyme activity and lignin synthesis in soybean rootsLin, Chih-Cheng 04 July 2002 (has links)
Copper-treated soybean ( Glycine max ) seedling shows significant inhibition in soybean root growth, and enhancement in POD activity. Cu is an efficient catalyst in the formation of several reactive oxygen species and free radical. The increase in POD activity induced by Cu might remove excess hydrogen peroxide serving a detoxifying role during Cu-treatment. The increase of cationic ( pI 8.9, pI 8.3 and pI 7.7 ) PODs and anionic ( pI 6.5, pI 5.6 and pI 4.4 ) PODs activities is accompanied by a rise of lignin contents in Cu-treated tissues. We suggest that the increase in cationic ( pI 8.9, pI 8.3 and pI 7.7 ) and anionic ( pI 6.5, pI 5.6 and pI 4.4 ) PODs induced by Cu is responsible for lignin synthesis in soybean roots during Cu treatment.

Effect of zinc on lignin biosynthesis in soybean rootsLee, Pei-Fang 11 June 2003 (has links)
Abstract
The significant root growth inhibition in zinc-treated soybean (Glycine max) seedling correlated with the increase of PODs and laccases activity. The increase of the activities of PODs (pI 8.3, pI 7.7, pI 4.8, pI 4.4 and pI 3.7) and laccases (pI 9.4, pI 8.3, pI 7.4, and pI 3.7) are accompanied by a rise of lignin contents in Zn-treated tissues. Our results suggested that laccases work during the early stage of Zn treatment. Laccases and peroxidases work cooperatively in lignin synthesis when the time of Zn treatment was prolonged.

A reliability assessment methodology for distribution systems with distributed generationDuttagupta, Suchismita Sujaya 16 August 2006 (has links)
Reliability assessment is of primary importance in designing and planning distribution
systems that operate in an economic manner with minimal interruption of
customer loads. With the advances in renewable energy sources, Distributed Generation
(DG), is forecasted to increase in distribution networks. The study of reliability
evaluation of such networks is a relatively new area. This research presents a new
methodology that can be used to analyze the reliability of such distribution systems
and can be applied in preliminary planning studies for such systems. The method uses
a sequential Monte Carlo simulation of the distribution systemÂs stochastic model to
generate the operating behavior and combines that with a path augmenting Max flow
algorithm to evaluate the load status for each state change of operation in the system.
Overall system and load point reliability indices such as hourly loss of load, frequency
of loss of load and expected energy unserved can be computed using this technique.
On addition of DG in standby mode of operation at specific locations in the network,
the reliability indices can be compared for different scenarios and strategies for
placement of DG and their capacities can be determined using this methodology.

Differential responses of peroxidases during the formation of adventitious root in hypocotyl cuttings of soybeanHuang, Yi-chi 09 February 2009 (has links)
The auxins, including indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) and naphthaleneacetic acid (NAA), promotes the formation of adventitious root in hypocotyls of soybean (Glycine max). IBA significantly promotes the formation of adventitious roots more than IAA and NAA . The activity of anionic pI 3.7 peroxidase (POX) and cationic pI 8.5 POX were inhibited by exogenous auxins during the induction of adventitious root on day 2. Besides, the activity of pI 5.3 POX was enhanced by IBA during the initiation stage on day 4. The increase of the activity of pI 5.3 POX was accompanied by the increase of H2O2 levels. In the previous researches, it shows that the promoter of pI 8.5 POX gene contains both ARF/AuxRE and CATATGGMSAUR motifs that are responded to auxins. In this studies, the pI 5.3 POX gene, which responses to auxins a day or two later, contains only ARF/AuxRE motif. The regulation of pI 5.3 POX gene is probably initiation phase-dependent. The results suggest that anionic pI 5.3 POX produces significant amount of H2O2 through the binding of auxin to POX and mediate the auxin signaling pathway leading to plant growth .
