Of Agriculture for Official Use

™?™ArS,EDc.BY THE AGRICULTURAL OF AGRICULTURE FOR OFFICIAL USE 15 Plants for conservation of soil and water in arid ecosystems H. L. Morton Arid Land Ecosystems Improvement. AgriculturalResearch Service, U.S. Department of Agriculture. 2000 E. Allen Rd. Tucson. AZ85719. USA Introduction Soil and water are the critical resources of the world, and they are especially critical in arid and semi-arid regions. Unfortunately they have been squandered through unwise and foolish use. Accelerated soil erosion has been a problem associated with dry land farming and grazing management in semi-aridareas of the world for as long as agriculture has been practiced. Successful ancient cropping practices were able to cope with the problem of soil erosion and lowered fertility mainly through a system of shifting cultivation (Leonard 1973). However increasing population pressure has resulted in grazing and cultivation, for all practical purposes, of all suitable land. Severe droughts, overgrazing, removal of grasses, trees and shrubs have caused severe losses of both soil and water in many regions of the world. This paper will focus on some of the physical processes involved in soil erosion and water loss and on plants known to be useful for their conservation in arid eco systems. Additional reviews of soil eriosion by wind and water with descriptions of control measures to which the reader can refer for greater detail are by Bennett (1931), FAO (1960 & 1965), and by Cannelland Weeks (1979). Most technical problems concerning soil and water conservation have been solved or are solvable with continued research effort. The problems which are not so easily solved are those associated with man.

Antimicrobial and Cytotoxic Potential of Silver Nanoparticles Synthesized Using Rheum Emodi Roots Extract

NEW FRONT. CHEM. (2015) Former: Ann. West Univ. Timisoara – Series Chem. Volume 24, Number 2, pp. 121-135 ISSN: 1224-9513 ISSN 2393-2171; ISSN-L 2393-2171 © West University of Timișoara Article ANTIMICROBIAL AND CYTOTOXIC POTENTIAL OF SILVER NANOPARTICLES SYNTHESIZED USING RHEUM EMODI ROOTS EXTRACT Deepika Sharmaa, Lalita Ledwania., Nitu Bhatnagara Manipal University Jaipur, Rajasthan, India ABSTRACT Antimicrobial and cytotoxic potential of silver nano particles (AgNPs) synthesized through greener route using R. emodi root extract was investigated. The synthesis of AgNps was confirmed by visualizing the colour change which shows surface plasmon resonance (SPR) peak at 425 nm. FTIR analysis indicates the involvement of anthraquinone pigments, in capping and stabilization of AgNps. FESEM, XRD, TEM, with EDX display the formation of crystalline AgNps with face centered cubic (FCC) symmetry with average size 27.5nm. AgNps were found to exhibit significant antimicrobial activity. Similarly, synthesized AgNps show substantial change in cytotoxicity against human breast lines (MCF-7 cell lines).

INTRODUCTION In the present era of nanotechnology, nanoparticles have found tremendous applications in various fields such as optical polarizability, catalysis, electronics and medicine [1-3]. Copper, silver, gold have unique properties that offer numerous application in audiophile, photonics, photography, biological labelling and also have scientific application [4-5]. Literatures have reported the use of diverse biological regime such as plants extract, algae, diatom, fungi and bacteria for the synthesis of nanoparticles [6-10].
Vegetation Classification and Mapping Program List of California Vegetation Alliances October 22, 2007

Department of Fish and Game Biogeographic Data Branch Vegetation Classification and Mapping Program List of California Vegetation Alliances October 22, 2007 Introduction: This document provides the Vegetation Classification and Mapping Program’s currently accepted list of vegetation alliances. It is based on the classification put forth in the upcoming second edition of “A Manual of California Vegetation,” (MCV) which is the California expression of the National Vegetation Classification (Grossman et al. 1998). This classification is hierarchical in nature: alliances are the generic vegetation unit and associations the specific unit. We hope to publish a list of accepted associations in the near future. This list is structured differently than previous lists. It emphasizes the relationship of the California alliances with the current National Vegetation Classification System (NVC). NVC codes and names, if they have been identified, are shown in brackets. Those lacking NVC codes and titles indicate new alliances that have not been discovered in currently funded collaborative projects with NatureServe. Those listed in brackets have full descriptions viewable using the following link: http://www.natureserve.org/explorer/servlet/NatureServe?init=Ecol California community codes follow the same format as in previous editions and are based on the Holland coding system (Holland 1986) with additional modifiers to accommodate for new types and the richer detail now currently understood in the California vegetation classification. Semi-natural Stands and Unique Stands: In addition to alliances, this list includes Semi-natural stands and unique stands. Semi-natural stands are strongly dominated by non-native plants that have become naturalized in the state; no alliances are defined by non-natives.
