The dispersion relation for general dust low frequency electrostatic surface waves propagating on an interface between a magnetized dusty plasma region and a vacuum is derived by using specular reflection boundary conditions both in classical and quantum regimes. The frequency limit ω ≤ωei ≤ ωce is considered and the dispersion relation for the Dust-Lower-Hybrid Surface Waves （DLHSW＇s） is derived for both classical and quantum plasma half-space and analyzed numerically. It is shown that the wave behavior changes as the quantum nature of the problem is considered.

A native herbaceous community exerts a strong allelopathic effect on the woody range-expander Betula fruticosa

The 1st Session of 2011 Workshop of Pakistan Academy of Sciences

作者： Saifuddin Ahmad Jilani m.ayub Khan YousufZai Department of Physics Institute of Space & Planetary AstrophysicsUniversity of Karachi Department of Applied Physics Solar-Terrestrial & Atmospheric Research Wing and Institute of Space & Planetary Astrophysics University of Karachi

In this communication we have presented the existence of solar flares and their variability along with the correlation structure of ozone concentration. This can be accomplished by analyzing the data of solar flare duration and ozone content. The supremacy of gradual flares in depletion of ozone was recognized. Exploratory Data Analysis approach has been utilized to find the contribution of solar flares in ozone layer depletion.

Improving organizational performance can be achieved through business process redesign (BPR). When it comes to modern work practices, organizations must often redesign their processes to keep up. This is where enterprise software comes in, offering a common data infrastructure that enables different parts of the organization to access all necessary financial data. The architecture of network accounting business process is divided into three layers. The core layer lies in the enterprise LAN that it can integrate six business processes information into one unity of financial information and non-financial information, including purchasing, inventory, production, sales, finance and customer service, and it can generate flexibly a variety of accounting statements to meet fully the information users’ demands by providing more complete and more valuable related information. The second layer lies in Intranet among enterprises based on the core layer that it can support the link of business processes and the inter-sharing of information among node enterprises of SCm and other external enterprises. The third layer lies in Internet based on the second layer that it can fit society, enterprise and individual together, the specific lays the solid foundation of business collaboration, remote management, online management and centralized management. The operating mechanisms of the network accounting business processes are as follows. When the business event occurs, the probe can get the event information in real-time and the result is stored in the database. meanwhile, the drive controller can control the business events in real-time by gaining control criteria and standards from database. In case the standard is exceeded, the event is not allowed to occur. Enterprise’ business staff or external personnel can output automatically the required results through report tools if they had the reading authority. Supported the information system and optimizing processes, the managers can
