The lithological classification of loess is based on physical and chemical properties, and the conditions of origin are partly or entirely neglected.
Experimental data obtained in the laboratory, coupled with chemical and physical theory, enable the conditions of origin of many naturally occurring minerals to be inferred.
The latter observation, together with the original findings of some of these spherules in crater-like structures in the landscape and including severely deformed rocks with some spherules being embedded in the fused crust of excavated rocks, points towards unique conditions of origin for these spherules and particles, possibly of exogenic origin.
{mathrm{emg}}_{mathrm{ijt}}=mathrm{f}left({mathrm{mac}}_{mathrm{ijt}}, {mathrm{lab}}_{mathrm{ijt}}right) (2 where lab ijt represents the labor market conditions of origin i and destination j in time t.
The first macroeconomic factors is {mathrm{emg}}_{ijt}= fleft({mathrm{mac}}_{ijt}right) (1 where emg ijt shows the flow female workers from i origin (Bangladesh) to j destination countries in time t, while mac ijt represents the macroeconomic conditions of origin and destination countries in time t.
Relevant characteristics identified in the literature were: gender, education level, years of experience, personal experience with the health condition, community of origin, age, household duties, marital status, social class and wealth (Table 3).
The IHR (2005) now follow an all-hazard approach, focusing on an "illness or medical condition, irrespective of origin or source, that presents or could present significant harm to humans" [ 1].
Sociodemographic variables recorded were marital status, living conditions, country of origin according to place of birth or parental place of birth, occupational status and education (highest level completed according to the Norwegian education system).
It is a fairly common condition of unknown origin, affecting smaller female dogs, often at about 5 years old.
