In this paper we develop a new approach to the study of uncountable fundamental groups by using Hurewicz fibrations with unique path-lifting property ( lifting spaces for short) as replacement covering spaces. particular, consider inverse limit sequence X . It is known that path-connectivity can be expressed means derived functor lim ← 1 , which is, however, notoriously difficult compute when g...

The study area is located around Gümüşyurt and Bayırlı Villages in Tokat/Artova city. Permian aged amphibolite rocks are formed the basement region. In upper part of this unit Silurian aged, grey-beige color recrystallized limestone found. There mainly metamorphic units metaclastics, having metabasic origin suh as chlorideschist, glaucophaneschist, micaschist composition white, cream, beige, bl...

The present study is related to our theoretical in­ vestigations [1—3] of diamino derivatives of the antiaromatic cyclopentadienyl cation (CPC). The theoretical results were confirmed with the brilliant synthesis of 6-amino-l,4-dimethyl-5,7-diphenyll,2,3,4-tetrahydrocyclopentapyrazin-6-ylium-tetrafluoroborate, carried out by Gompper et al. [4] and of some other stable cyclopentadienyl salts [5]...

Biomass can indicate plant growth status, so it is an important index for plant growth monitoring. This paper focused on the methodology of estimating the winter wheat biomass based on hyperspectral field data, including the LANDSAT TM and EOS MODIS images. In order to develop the method of retrieving the wheat biomass from remote sensed data, routine field measurements were initiated during pe...
