This paper comes to examine the intense reflection that arises around the issue of the fourth industrial revolution and the subsequent rapid changes. Changes that affect all areas of human existence, especially labour, drastically. Already from the beginning of the 21st century, international organizations (UN, UNESCO, OECD) are also keen to increase employability and develop relevant skills that can protect it.
Evaluating the Changes in Surface Properties of Acid-Leached Iliri Clay (Published)
Clay from Iliri was activated using hydrochloric and sulfuric acid of differing concentrations to acquire differing acidities. The chemical compositions of the raw clay and clay activated at different acid concentrations were analyzed to investigate the extent of cation dissolution. From the Na2O to CaO ratio, Iliri clay is swelling sodium bentonite mixed with feldspars, illite, kaolinite and plagioclase. The Langmuir isotherms of 1-aminobutane in isohexane agitated with clay slurries showed increase in clay acidity with increase in concentration of mineral acid used to leach the clay as well as the temperature at which the clay was thermally activated prior to experimentation involving adsorption of 1-aminobutane. The values of surface acidity, nm, for acid-leached Iliri clays ranged from 0.811×10-3 molg-1 to 6.7705×10-3 molg-1 and the kinetic equilibrium constant of adsorption, K, varied from 0.07828 to 0.7233 yet the surface area, A increased from 5.2702 x10-3 m2g-1 to 50.6700 x10-3 m2g-1 . Basing on acidity, pH, elemental and mineral compositions, the Iliri clay was resolved to contain montmorillonite.
The purpose of life cycles through which passes each organization and social system to which it belongs is in its holding phase permanent “Youth” in which the prevailing conditions for achieving permanent development and growth of the same. The changes occur as a necessary determinant for achieving this desired state that would assure the effective operation of the organization. Any change is followed by resistance by the direct implementers of the same (employees). The consequences and the final balances of such resistance solely depend on the competence of managers, especially in the phase of the initiative for change and leadership styles that same practice.
