Adsorption Studies Of Cu (Ii) And Pb (Ii) Metal Ions From Aqueous Solution Using Maize Cob As Biosorbent

ABSTRACT The use of raw maize cob (rmc) and activated maize cob (amc) as a low-cost natural adsorbent for the removal of Pb2+ and Cu2+ ions from simulated waste water was studied. Batch experiments were conducted to determine the effects of varying contact time, initial metal ion concentration, adsorbent dosage, pH and temperature of adsorption on adsorption equilibrium quantity (qe ) and percentage removal (% R). % R increased with increasing adsorbent dosage for the two metal ions. It also...

A Two-Small-Parameter Dynamic Buckling Analysis Of A Damped Quadratic-Cubic Nonlinear Structure

ABSTRACT The major goal of this research work is to determine the dynamic buckling load of a viscously damped imperfect quadratic-cubic elastic model structure, which is modeled by a nonlinear differential equation containing a load parameter. For a structure with small imperfections and subjected to step loading , the equation contains two small independent parameters, upon which asymptotic expansions are initiated. The nonlinearity is quadratic-cubic in nature and multiple-scaling two-timi...

This work seeks to solve resource managerial problems ranging from server maintenance cost, risk of loss of data, internal security issues, and availability of data for proper decision making. This work presents to tertiary institutions a model for designing a scalable and cost effective platform for institutional resource management on the cloud. The platform is called...

Variation In Levels Of Vitamins A And C With Maturity Of Amaranthus Hybridus (L) Leaves Grown In Different Soil - Types In Kwale County, Kenya

ABSTRACT The prevalence of vitamins A and C deficiencies (VAD and VCD) in Kenya are 84 % and 45 % respectively, pointing towards health hazards among human beings. The deficiencies are mainly attributed to poverty and limited accessibility to expensive but rich food sources that contain vitamins A and C. Fruits and vegetables are however cheaper and easily available as sources of vitamins A and C. These are grown in various soils and are consumed at various stages of maturity thus being facto...

A Fleet Information Management System

Abstract In urban transportation or freight distribution, the use of an initial distribution plan, although necessary, is by no means sufficient to address unexpected events such as mechanical failures, vehicle breakdown, total loss of transaction records that are likely to occur during delivery execution and may have adverse effects on system performance. These events cause deviations between the actual and desired state during the execution of the schedule or even after the schedule. Recen...

Chemical Composition Of Ocimum Kilimandscharicum And Ocimum Americanum And Their Bioactivities Against Sitophilus Zeamais

ABSTRACT The maize weevil, Sitophilus zeamais (Motchulsky), the lesser grain borer, Rhyzopertha dominica (Fabricius), and the Angoumois grain moth, Sitotroga cerealella (Oliver), are serious pests of stored grain in Kenya. The control of these insect pests relies heavily on the use of synthetic insecticides by better off farmers; but there is an increasing cost of application and erratic supply in developing countries. In addition, small-scale farmers cannot afford these commercial products a...
