in the process of vermicomposting, the earthworms eisenia fetida have been exposed to various metals with different concentrations to study the effects on worms’ bioaccumulation. the study was carried within 14 days of exposure. five different chemical compounds in various concentrations were added as mixture solutions to the experimental containers. metals concentrations were measured in earth...

a meshless approach, collocation discrete least square (cdls) method, is extended in this paper, for solvingelasticity problems. in the present cdls method, the problem domain is discretized by distributed field nodes. the fieldnodes are used to construct the trial functions. the moving least-squares interpolant is employed to construct the trialfunctions. some collocation points that are indep...

In this work, we develop a distributed least squares approximation (DLSA) method that is able to solve large family of regression problems (e.g., linear regression, logistic and Cox's model) on system. By approximating the local objective function using quadratic form, are obtain combined estimator by taking weighted average estimators. The resulting proved be statistically as efficient global ...

Object-oriented systems could use much of the functionality of database systems to manage their objects. Persistence, object identity, storage management, distribution and concurrency control are some of the things that database systems traditionally handle well. Unfortunately there is a fundamental difference in philosophy between the object-oriented and database approaches, namely that of obj...

agricultural extension workers’ service has been placed as the central pattern of agricultural transformation in general and smallholder farmers in particular. due largely to this commensurately known trend, identifying factors that determine farmers’ access to extension workers’ service and the effect of the service on crop yield was found to be imperative. cross sectional data was collected t...
