in order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five cms lines and four restorer lines (tester) were crossed in a line × tester scheme. hybrids were evaluated in a randomized complete block design with three replications in the agriculture research station, university of tabriz, in 2009 and 2010 growing seasons. plant height,...

New technologies tend to exert a profound influence on modern city life. This paper addresses the role of information and communication technologies (ICT) in the city. After a broad overview of the potential of ICT in a geographical setting and its possible impact on urban policy in regard to the ICT sector, the paper focusses attention on urban public policy in regard to the ICT sector. This s...

Investigations on changes in a rifle's barrel temperature during shooting in a rhythm typical for practitioners of Olympic shooting sports are presented. Walther KK300 (cal. 5.6 mm), a typical rifle often used in Olympic competitions, R50 RWS ammunition and a high speed thermographic camera were used in the study. Altair version 5 software was used to process thermal images and a stationary wav...

Mercury intrusion porosimetry (MIP) has been widely used to characterize the pore structure for various types of porous media. Several relationships between permeability and pore structure information (e.g., porosity and pore-size distribution) have been developed in the literature. This work is to introduce a new, and simpler, empirical equation to predict permeability by solely using the medi...

The paper discusses recent developments of German fiscal federalism—especially the Länderfinanzausgleich, i.e. Germany’s unique system of horizontal equalization. A ruling by the Constitutional Court has cracked the status quo, and the parties involved (federation and states) have begun a process of bargaining on a new equalization system. This process is assessed against the background of rece...

For stereotactic ablative body radiotherapy (SABR) in lung cancer patients, Radiation Therapy Oncology Group (RTOG) protocols currently require radiation dose to be calculated using tissue heterogeneity corrections. Dosimetric criteria of RTOG 0813 were established based on the results obtained from non-Monte Carlo (MC) algorithms, such as superposition/convolutions. Clinically, MC-based algori...

HER-2/neu expression is observed in 15-20% of all breast cancers and clinically relevant due to the several anti-HER2 treatment modalities. status assessed quantified using immunohistochemistry (IHC). Although well-standardized clinical practice, it still subject interobserver variability. Automating scoring can improve accuracy, efficiency, consistency, cost-effectiveness while reducing pathol...
