As a basic function urban complex is a city function carrier of space , resources and material (buildings and facilities), and as a carrier of the functions in the city including information, finance, insurance, science and technology, commercial, residential, commercial, live abroad, exhibition, sightseeing, recreation and so on, which provided material conditions and environmental space for the people carrying out various activities in the city.
Modern urban complex (Forum News) often become a venue of cultural undertakings in a city or local area about education, science, culture, physical and recreational and so on.

New materials and better application of new bit types have driven penetration rates and bit life steadily higher which can only be determined through the evaluation of their performances.
Plinninger et al [8] also indicated that the rate of penetration denotes the depth penetrated per unit time while the wear rate describes the velocity of material removal from the bit and it a basic factor for the calculation of bit consumption and wear costs.
Materials and Methods The study area covers Ewekoro limestone deposit in Ewekoro local government of Ogun State, Nigeria.

Effect of Host Media on Microbial Influenced Corrosion due to Desulfovibrio desulfuricans Ajay K Singh1,a and Suman Lata1,b 1Department of Applied Science & Engineering, IIT Roorke, Saharanpur-247001, India aajaysfpt@iitr.ernet.in, bhellosuman17380@gmail.com Keywords: Microbial influenced corrosion; Desulfovibrio desulfuricans; stainless steels; Sodium chloride; Sea water; Extracellular polymeric substances.
Introduction Sulfate reducing bacteria (SRB) Desulfotomaculum are anaerobic and recognized to affect the materials through MIC causing localized attack on stainless steels resulting in their unexpected failure [1].
Corrosion on materials in these media could be due to combined effect of chemicals and the microbes together with the possibility of microbial activity getting influenced by the chemicals present in the media.
Thus, a correlation is expected between MIC of iron and the protein content in the biofilm formed on the corroded material.

Introduction Polysaccharides is an attractive polymeric material to prepare nanoparticles for drug delivery since it is highly stable, safe, non-toxic, hydrophilic, biocompatible and biodegradable [1].
Nanosized material used in drug delivery applications possesses several advantages such as high drug encapsulation efficiency, efficient drug protection against chemical or enzymatic degradation, unique ability to create a controlled release, cell internalization as well as ability to reverse the multidrug resistance of tumor cells [4].
Experimental Materials.
It can be concluded that CL-GA nanoparticles have the potential to be used as a biopolymeric material for drug delivery.
