We report the observation of new properties of primary cosmic rays, neon (Ne), magnesium (Mg), and silicon (Si), measured in the rigidity range 2.15 GV to 3.0 TV with 1.8 × 10 6 Ne, 2.2 × 10 6 Mg, and 1.6 × 10 6 Si nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The Ne and Mg spectra have identical rigidity dependence above 3.65 GV. The three spectra have identical rigidity dependence above 86.5 GV, deviate from a single power law above 200 GV, and harden in an identical way. Unexpectedly, above 86.5 GV the rigidity dependence of primary cosmic rays Ne, Mg, and Si spectra is different from the rigidity dependence of primary cosmic rays He, C, and O. This shows that the Ne, Mg, and Si and He, C, and O are two different classes of primary cosmic rays.

Protein-calorie malnutrition is frequent in haemodialysis patients. Fat depletion predominated in both sexes. Duration of dialysis and protein catabolic rate related to ideal body weight was the only predictor which could be influenced by a nutritional intervention. Morbidity appeared to be influenced by the comorbidity index and age was the strongest predictor of mortality. The only nutritional measurements predictive of morbidity and mortality were serum albumin and total lymphocyte count respectively. Therefore, the influence of malnutrition in morbidity and mortality can not be definitively stated.
