Group 15 elements major patterns

The majority of vomerolfactory effects discussed relate to intra-specific patterns, most concerned with social discriminations. Individual and or group membership, hierarchical status —often aggression-related, are among many non-sexual but socially indispensable elements. Social systems with evident female dominance are not infrequent among... 

Similar sorts of results may be found with the nitrate anion. In this case, the nitrate ion itself has a characteristic absorption in the ultraviolet. When paired with a transition-element cation, in alcoholic solution, this absorption is markedly altered (2). It also shows alterations with other cations. In certain ketone and ether solutions, it has been possible to demonstrate further that the vibrational spectrum of the nitrate ion has been altered in such a pattern as to be consistent with a binding of one of the nitrate oxygens to the cation (2), so that major vibration now occurs between this oxygen and the rest of the bound nitrate group. 

The distribution of essential and potentially toxic elements in different gross fractions is the preliminary step to study the particular chemical forms in which they are present in milk [105]. Multielemental distribution patterns in human, cow, and formula milks have been reported by the Sanz-Medel group [106]. Total elemental distributions in skimmed milk and/or milk whey samples were obtained after removing fat and/or caseins by ultracentrifugation. Then, in order to destroy the organic matter, each fraction (whole milk, skimmed milk, and milk whey) was digested by MW-assisted digestion for their minor and major elemental analysis. 

Coefficients of the elemental concentrations on the first principal component (Table II) show the pattern expected for a temper-related dimension the signs are positive for all variables except K and Ba, which are negative. Thus, the group separation on principal component No. 1 shown in Figure 6 can be interpreted as temper-related. As expected, the two major groups evident on the plot are (I) hypothetical fine-paste mixtures along with raw clay and (2) hypothetical medium-paste mixtures along with real sherds.
