A MATHEMATICAL PATTERN OF THE RELATION MAN-ENVIRONMENT, REPRESENTED BY ANTICIPATORY SYSTEMS

Author: Eufrosina OTLACAN, Lidia CRISTEA Publishing Date: 2007 E-ISSN: 2147-9364 Volume 22 Issue 1-2 ABSTRACT:In a pair of mixed advanced-retarded differential equations we consider man as being the master system and the environment as the slave system. This is the case when man’s behaviour is dependent on a future state of the environment, while the environment’s rate of change is dependent

FORMATION CONDITION AND PROPERTIES OF THE VARIOUS TYPES OF GYPSUM OCCURRENCES AT SIVRIHISAR (ESKIŞEHIR, TURKEY)

Author: T. ALTAY, M. Ç. KARAKAYA, Y. ERKAN Publishing Date: 2007 E-ISSN: 2147-9364 Volume 22 Issue 1-2 ABSTRACT:The study area is located in southeast of the town of Sivrihisar (Eskişehir, Central Anatolia). The rocks (Neogene Age) located in the study area is divided into two lithostratigraphic units, namely İlyaspaşa (Lower-Middle Miocene) and Sakarya (Upper Miocene-Pliocene) formations. Sakarya formation is the subdivided
