Abstract The article describes studies on the separation of uranium from acid pregnant leach solutions obtained from Polish uranium ores: dictyonema shales and sandstone rocks. Ion exchange chromatography was applied for uranium sorption, using commercially available, strongly basic anion exchanger, Dowex 1. In model experiments, the influence of degree of crosslinking of Dowex 1 on the efficiency of uranium extraction was investigated. The effect of H2SO4 concentration on the breakthrough curve of uranyl ions for the Dowex 1 resins, of different crosslinking: X4, X8 and X10, was examined. Unexpectedly high increase of exchange capacity of uranium was observed in case of Dowex 1X10. This gives potential opportunity of improving the effectiveness of uranium recovery process. Applying column packed with Dowex 1X10, ‘yellow cake’ with ca. 92% yield and high purity of recovered uranium was obtained. A block diagram of the procedure for uranium and lanthanides extraction from acidic leach liquor has been proposed.

Traditional Medical Model

Purpose Person-centered care shifts the focus of treatment away from the traditional medical model and moves toward personal choice and autonomy for people receiving health services. Older adults remain a priority for person-centered care because they are more likely to have complex care needs than younger individuals. Even more specifically, the assessment and treatment of swallowing disorders are often thought of in terms of setting-specific (i.e., acute care, skilled nursing, home health, etc.), but the management of dysphagia in older adults should be considered as a continuum of care from the intensive care unit to the outpatient multidisciplinary clinic. In order to establish a framework for the management of swallowing in older adults, clinicians must work collaboratively with a multidisciplinary team using current evidence to guide clinical practice. Private practitioners must think critically not only about the interplay between the components of the evidence-based practice treatment triad but also about the broader impact of dysphagia on caregivers and families. The physical health and quality of life of both the caregiver and the person receiving care are interdependent. Conclusion Effective treatment includes consideration of not only the patient but also others, as caregivers play an important role in the recovery process of the patient with swallowing disorders.

Light Absorbance

Summary1. Platelet suspensions were exposed to hypotonic stress. Several parameters of the changes in light absorbance were investigated i. a. the initial decrease in absorbance (Amin), the maximal rate of the recovery process (Vmax), and the value of the absorbance two hours after mixing the platelet suspension with the hypotonic solution.2. The ratio Vmax/Amin appeared to be independent of both platelet concentration and, within a specific range, decrease in osmolarity.3. Cryoprotectants appeared to disturb the response to hypotonic stress.4. Cryopreservation caused a decrease in the light absorbance of the platelet suspension, of Amin, and of the recovery process.
