Besides demographic, clinical, familial, and biographical factors, culture and ethnicity may plausibly influence the manifestation of hallucinations. The purpose of this study was to investigate the influence of culture on the frequency of different kinds of hallucinations in schizophrenia.

In Georgia there are many sites which have archeological value and interest on the side of cultural heritage but none of these sites is used as the experimental basis for modern scientific technologies. For this aim it was created a research group, including specialists in archeology, physics and radiology for development of new physical methods for dating of archeological materials found in Georgian. The first interesting results have already been by Electron Paramagnetic Resonance (EPR) method which we shortly present in this article.

Recent archaeomagnetic data from ancient Israel revealed the existence of a so-called “Levantine Iron Age geomagnetic anomaly” (LIAA) which spanned the first 350 years of the first millennium before the Common Era (B.C.E.) and was characterized by a high averaged geomagnetic field (virtual axial dipole moments, VADM > 140 Z Am2, nearly twice of today's field), short decadal-scale geomagnetic spikes (VADM of 160–185 Z Am2), fast field variations, and substantial deviation from dipole field direction. The geographic constraints of the LIAA have remained elusive due to limited high-quality paleointensity data in surrounding locations. Here we report archaeointensity data from Georgia showing high field values (VADM > 150 Z Am2) in the tenth or ninth century B.C.E., low field values (VADM < 60 Z Am2) in the twelfth century B.C.E., and fast field variation in the fifth and fourth centuries B.C.E. High field values in the time frame of LIAA have been observed so far only in three localities near the Levant: Eastern Anatolia, Turkmenistan, and now Georgia, all located east of longitude 30°E. West of this, in the Balkans, field values in the same time are moderate to low. These constraints put geographic limits on the extent of the LIAA and support the hypothesis of an unusually intense regional geomagnetic anomaly during the beginning of the first half of the first millennium B.C.E., comparable in area and magnitude (but of opposite sign) to the presently active South Atlantic anomaly. ©2017.

This paper summarizes recent developments in the synthesis, application and mechanistic studies on polysaccharide-based chiral stationary phases (CSPs) for liquid phase separation techniques. Together with applications in conventional high-performance liquid chromatography (HPLC) applications in nano-liquid chromatography (nano-LC), capillary electrochromatography (CEC), super/sub-critical fluid chromatography (SFC) and preparative and product scale separations are also summarized. In the final part of the overview mechanistic aspects and some unusual effects observed in HPLC with these materials are shortly discussed and the author's view regarding future trends in this field is provided.

This review summarizes the separation selectivity in chiral capillary electrophoresis with charged selectors. Different parameters for a description of the separation selectivity, i.e., the absolute and the relative mobility difference between the enantiomers, the ratio of apparent mobilities and the ratio of effective mobilities as well as the intrinsic (recognition) selectivity, are compared. The electrophoretic mobility of the enantiomers and their migration with the electroosmotic flow are discussed from the viewpoint of separation selectivity. The affinity and mobility- related contributions in the separation selectivity with charged chiral selectors are separately considered. The selectivity of the separations using charged chiral selectors as carriers, in systems with a combination of chiral selectors as well as selectivity in chiral capillary electrochromatography are also briefly addressed.
