The main purpose of this paper is to the make the fundamentals of continued growth of broadband wireless sound. The opportunity for BWA/WiMAX to serve those who want to switch to broadband service is huge in many parts of the world where wire line technologies may not be feasible. In wireless channel air link is the most expensive than other system resources and therefore the controlling system element related to capacity in wireless access networks is the main area of consideration. For this we are tryingto implement the entire algorithm for different system parameter and traffic cases to ease the Mobile WiMAX planning problem. The DL:UL ratio assignment was done in an efficient way to provide both directions with the required capacity i. e. 104 users in 10 MHz bandwidth and 216 users in 20 MHz bandwidth.

This specification covers the standardization of the plant Bidens pilosa (Asteraceae). It is widely used as anti-inflammatory, muscle relaxant, antialergic, pain-relieving, anti-bacterial, hepatoprotective. The plant material was subjected to pharmacognostical studies and physiochemical parameters. Dried plant material was subjected to various physiochemical parameters like extractive values, ash values, cold maceration, chromatographic methods, loss on drying, successive extraction and heavy metal analysis. These parameters can be utilized for quick identification of the Bidens pilosa and are particularly useful in powdered form.Keywords

Grewia asiatica is a small deciduous tree consisting of ripe fruits, seeds, flowers, bark and leaves of the plant belonging to family Tiliaceae. In present study, various standardization parameters of fruits like macroscopical, microscopical characters, physicochemical parameters like total ash (5.16%), water soluble ash (2.5%), acid insoluble ash (1%), sulphated ash (0.66%), loss on drying (8.3%), swelling index (0.1), foaming index (less than 100), successive extractive values in various solvents like petroleum ether (1.6%), benzene (2.1%), chloroform (2.6%), ethyl acetate (3.7%), methanol (30.9%). Cold Maceration values, petroleum ether (3%), benzene (3.3%), chloroform (4%), ethyl acetate (4.3%), methanol (45.6%). Behaviour on treatment with different chemical reagents of the dried fruits, fluorescence characters under visible and ultralviolet light were studied to fix some pharmacognostic parameters that vary from region to region. Preliminary phytochemical studies on different extracts were reported.

Corn silk is collection of the stigmas of corn (Zea Mays). Zea Mays is a monotypic genus of short or tall, generally robust, monoecious, annual grasses belonging to family Poaceae. The plant is reported to possess antifungal, antiviral, diuretic, and antitumour activity. The plant material was collected from Punjab and authenticated by taxonomist of GNDU, Amritsar. In present study, various standardization parameters of corn silk like macroscopical, microscopical characters, physicochemical parameters like total ash (6.5% ), water soluble ash (3.6%), acid insoluble ash (1.65%), sulphated ash (1%), foreign organic matter, loss on drying (9.8%), swelling index (2.5%), foaming index (less than 100), successive extractive values in various solvents like petroleum ether (2.1%), benzene (2.4%), chloroform (2.9%), ethyl acetate (3.4%), methanol (28.5%). Cold Maceration values, petroleum ether (2% ), benzene (2.3%), chloroform (2%), ethyl acetate (3%), methanol (30%). Behaviour on treatment with different chemical reagents of the dried corn silk, fluorescence characters under visible and ultralviolet light at 254 nm and 366 nm were studied to fix some pharmacognostic parameters that vary from region to region. Preliminary phytochemical studies on different extracts were also reported.
