We determined levels of hepatic cytochrome P4501A (CYP1A) mRNA, hepatic DNA adducts, and fluorescent aromatic compounds (FACs) in bile, a measure of exposure to polyaromatic hydrocarbons, in Atlantic tomcod from six river systems ranging from highly polluted to relatively pristine on the northeast North American coast (the Hudson River, New York; the St. Lawrence River, Quebec; the Miramichi Ri...

Krank - biyel mekanizmaları, kullanım alanı çok geniş olan bir hareket mekanizmasıdır ve basit, kullanışlı olması dolayısıyla katlı materyalleri kesme makinelerinde oldukça tercih edilmektedir. Bu mekanizmaya dayanan sistemlerinde, hızını arttıran parametrelerden biri krank uzunluğu değişiminin sisteme etkilerini görmek için Matlab / Simulink ile simülasyon gerçekleştirilmiştir. Ayrıca serilmiş...

This is a review of selected topics from recent work on symmetry charges in asymptotically flat spacetime done by the author collaboration with U. Kol and R. Javadinezhad. First we reinterpret reality constraint boundary graviton as gauge fixing new local symmetry, called dual supertranslations. extends BMS group bears many similarities to (magnetic) electrodynamics. We use this propose descrip...

This study proposed a natural-rule-based-connection (NRBC) method to connect river segments after water body detection from remotely sensed imagery. A complete river network is important for many hydrological applications. While water body detection methods using remote sensing are well-developed, less attention has been paid to connect discontinuous river segments and form a complete river net...

Freshwater populations of three-spined sticklebacks (Gasterosteus aculeatus) in northern Germany are found as distinct lake and river ecotypes. Adaptation to habitat-specific parasites might influence immune capabilities of stickleback ecotypes. Here, naive laboratory-bred sticklebacks from lake and river populations were exposed reciprocally to parasite environments in a lake and a river habit...

With the rapid development of B2C e-commerce model and continuous rise fan economy, KOL (Key opinion leader), key leader in social media platform "social content + e-commerce" new era, has become first factor affecting consumers' willingness to buy. This paper takes Little Red Book as research sample, through method questionnaire survey, specifically analyzes its marketing mode, advantages pros...

Diyarbakır'ın Eğil yöresinden farklı iki lokaliteden toplanan 11 (10♀♀, 1♂♂) Pipistrellus kuhlii örneğinin morfolojik ve karyolojik özellikleri incelenmiştir. Morfolojik karakterler, ölçüler özellikler daha önce yayınlanmış çalışmalarla karşılaştırılmıştır. Diploid kromozom sayısı 2n = 44, kol NF 54 otozomal NFa =50'dir. X kromozomu orta büyüklükte metasentrik, Y nokta şeklinde olup, son akrose...

Aims Factors limiting distributions of species are fundamental to ecology and evolution but have rarely been addressed experimentally for multiple species. The conspicuous linear distribution patterns of plant species confined to river corridors in the Central European lowlands constitute an especially long-standing distribution puzzle. We experimentally tested our novel hypothesis that the tol...

The carbon isotopic composition (δ13C) of dissolved and particulate inorganic carbon (DIC; PIC) was used to compare and analyze the origin, dynamics and evolution of inorganic carbon in two headwater tributaries of the Xi River, Southwest China. Carbonate dissolution and soil CO2 were regarded as the primary sources of DIC on the basis of δ13CDIC values which varied along the Nanpan and Beipan ...

Google Earth, a software based on satellite’s images and database of navigation, gains features of high resolution, integrated images, quick update, convenience, simpleness and free cost. Practice of this software shows that it plays an important role in mapping, construction and river research. Based on the fundamental features of Google Earth, this passage makes an introduction to its applica...
