the anti-senescence biogenic polyamines (pas) putrescine (put), spermidine (spd) and spermine (spm) are involved in plant growth processes and responses to stress. the physiological mechanism of exogenous put to affect the senescence of cut lisianthus flowers during vase life was investigated. fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mm put and then...

galbanic acid, a sesquiterpene coumarin from ferula szowitsiana , and conferol, another sesquiterpene coumarin from f. badrakema , were evaluated for their effects on the reversal of multi-drug resistance in clinical isolates of staphylococcus aureus and escherichia coli , respectively. neither galbanic acid (up to 1000 μg/ml) nor conferol (up to 400 μg/ml) by itself shows any antibacterial act...

This paper deals with the optimization of the catalytic convertor for CNG Lean burn Engine based on BS4 compliances. In addition to the present catalytic convertor the work is carried out for the optimization of catalytic convertor and also to meet the BS4 compliance and also to reduced cost for the same. In this project we have prepared the samples with some variation in the substrate with res...

We compare average impulse response of rate of return curves computed from more than sixty-seven years of historical Dow Jones Industrial, Transportation, and Utility Average closing values. The curves are relatively consistent in shape until the 1990s, when marked changes, indicative of improved market efficiency, occur for the Dow Jones Industrial Average. We argue that the effect is a result...

In this paper we treat the time evolution of unitary elements in the N level system and consider the reduced dynamics from the unitary group U(N) to flag manifolds of the second type (in our terminology). Then we derive a set of differential equations of matrix Riccati types interacting with one another and present an important problem on a nonlinear superposition formula that the Riccati equat...

A Radial Distribution network is important in power system area because of its simple design and reduced cost. Impact of Distributed generation in radial distribution feeder is increased because of its application of green technology and it also meet out some of the power system issues. Allocation of Distributed Generation at non-optimal places leads to increased power loss and reduced bus volt...

Many production facilities generate and update production schedules. Rescheduling is necessary because the manufacturing system is dynamic and unexpected events occur. This paper discusses rescheduling policies and how they affect the performance of manufacturing systems. The benefits of proper rescheduling include improved manufacturing system performance with reduced cost due to computational...

Antennas are becoming crucial in an increasingly growing number of applications namely with the emerging of the wireless internet communications, military systems like aircrafts, missiles and submarines or even oil drilling systems where efficiency, compactness and cost play a decisive role. Nonetheless, a major drawback of such solutions is that the aforementioned criteria are hard to simultan...

There is growing interest in the notion of software development through the planned integration of COTS (Commercial Off-The-Shelf) products. The potential advantages of this integrationcentric approach are shorter development time and reduced cost. Often a COTS based development process consists of an evaluation, selection, adaptation, integration, and evolution of components obtained from exte...

Shipment consolidation has been advocated by researchers and politicians as a means to reduce cost and improve environmental performance of logistics activities. This paper investigates consolidated transport solutions with a common shipment frequency. When a service provider designs such a solution for its customers, she faces a trade-o : to have the most time-sensitive customers join the cons...
