The article is devoted to the results of spectral analysis of effective flushing liquid with the use of lightweight polymeric reagent (LPR). On the basis of spectral research it is shown that the mechanism of ion exchange of particles of flushing liquid (replacement reaction) at replacement of mineral in the crystal lattice by cat ions of disperse medium is a permanent replacement of organic and inorganic cat ions of flushing liquid with rock particles and whole groups of dispersive medium. The results of the processes of addition of fluids and rock elements to the flushing liquid particles, as well as simultaneously occurring ion-exchange and none change processes determining the mechanisms of inhibition (reduction of hydrophilicity), stabilization and colloidal protection in flushing liquids are obtained.

Exchange Resins

Those samples which swell rapidly when exposed to water are, at best, difficult to section for transmission electron microscopy. Some materials literally burst out of the embedding block with the first pass by the knife, and even the most rapid cutting cycle produces sections of limited value. Many ion exchange resins swell in water; some undergo irreversible structural changes when dried. We developed our embedding procedure to handle this type of sample, but it should be applicable to many materials that present similar sectioning difficulties.The purpose of our embedding procedure is to build up a cross-linking network throughout the sample, while it is in a water swollen state. Our procedure was suggested to us by the work of Rosenberg, where he mentioned the formation of a tridimensional structure by the polymerization of the GMA biproduct, triglycol dimethacrylate.

Abstract. The implementation of a new pay system is a balancing act that produces uncertainty and draws employees’ attention to the fulfillment of exchange agreements. Transformational leadership may be essential during these change processes. Based on psychological contract theory, we expected that transformational leadership impacts job satisfaction and affective organizational commitment through the fulfillment of relational psychological contracts, while the fulfillment of transactional psychological contracts may be crucial for employees’ pay and bonus satisfaction. We assessed 143 employees nested within 34 teams before and after (24 months) a pay for performance (pfp) system was introduced. Our results supported the mediation hypotheses considering job and pay satisfaction, but not considering commitment. Unexpectedly, the effect on bonus satisfaction was mediated via relational psychological contracts.
