Speciation of copper in a contaminated soil during electrokinetic remediation (EKR) assisted by H3PO4 was studied by in situ X-ray absorption near edge structural (XANES) spectroscopy. The least-square fit of the XANES spectrum showed that CuCO3 (68%) and CuCl2 (32%) were the major copper species in the contaminated soil. In the presence of H3PO4 (40%), most of CuCl2 and about 24% of CuCO3 were...

Electronic Knowledge Repository (EKR) is one of the most commonly deployed knowledge management technologies, yet its success is hindered by employees’ underutilization and further complicated when implemented in the multinational context. To address these challenges, we propose a research model by conceptualizing employees’ knowledge seeking via EKR as a survival-centric behavior, identifying ...

In the present competitive organizational environment more organizations are implementing knowledge management initiatives to gain strategic advantage. One such initiative is that of implementing electronic knowledge repositories (EKR) which often leads to a rapid increase in the quantity of information employees must process daily, raising concerns of employees being overloaded. This is especi...

The classical Erdős-Ko-Rado theorem states that if k ≤ ⌊n/2⌋ then the largest family of pairwise intersecting k-subsets of [n] = {0, 1, . . . , n} is of size ( n−1 k−1 ) . A family of k subsets satisfying this pairwise intersecting property is called an EKR family. We generalize the EKR property and provide asymptotic lower bounds on the size of the largest family A of k-subsets of [n] that sat...

Let G = (V,E) be a graph. Let IG be the family of all independent sets of G. For r ≥ 1, let I G := {I ∈ IG : |I| = r}. For v ∈ V (G), let I (r) G (v) denote the star {A ∈ I G : v ∈ A}. G is said to be (strictly) r-EKR if there exists v ∈ V (G) such that (|A| < |I G (v)|) |A| ≤ |I (r) G (v)| for any non-star family A of pair-wise intersecting sets in I G . Let Γ be the family of graphs that are ...

PURPOSE To evaluate the accuracy of central corneal power measurements by Scheimpflug imaging (Pentacam) for eyes that had corneal refractive surgery. METHODS This study comprised two groups: a pilot group of 100 eyes with prior hyperopic or myopic LASIK that did not have cataract surgery, and a test group of 41 eyes with prior radial keratotomy (RK) and cataract surgery. In the pilot group, ...

Among the recent challenges faced by managers is the ability to manage knowledge sharing effectively so that knowledge can be utilized strategically for the benefit of the organization. Since knowledge sharing cannot occur without contribution of knowledge, most research so far has been devoted to the contribution aspect of knowledge sharing. However, knowledge re-use, another important goal of...
