The term 'Workers' Councils' can perhaps stand as a catchall title for an unpremeditated, quasi-spontaneous, 'groundup' organisational form reproduced over many periods and across many countries by groups of workers previously unaware of such a structure or of its historical precedents. Its highest form the Soviet, its 'lowest' the simple workplace representatives' committee, this formation rec...

the gobies are non-commercial fishes in the iranian waters of the caspian sea for which population dynamics and stock status are poorly known. in this survey, we tried to define species diversity and catch per unit effort (cpue) of gobiidae by using beach seine nets in salmanshahr, the southern caspian sea. from march 2011 to april 2012, 224 specimens representing 4 gobiid species, belonging to...

This article analyses the development of competitive party politics in post-communist East Central Europe from a comparative perspective. The central concerns are party system stabilisation and change in Hungary, Poland, the Czech Republic and Slovakia, and implications for comparative theory. Starting from Lipset and Rokkan’s ‘cleavage model’, the article assesses the relevance of their key va...

b a ckground : this study aimed to identify and determine the larval and adult mosquitoes (culicidae) fauna in hamedan county, western iran. m e t hods: it was a cross-sectional study which took place in four area of the hamedan county. sampling methods for larvae, pupae and adults were dipping, hand catch, night catch and total catch. larvae and adult mosquitoes col- lected and were sent to la...

In this paper, we propose a new wireless scheduling algorithm for the IEEE 802.11e HCF. The algorithm grants the mobile stations variable time for the upstream data flow in proportion to the queue size of the transmission buffer. At the same time, it retrieves half of the extra time allocated in previous cycle from those flows whose requirement has stopped. Hence, the system achieves stability ...

This paper proposes a dynamic bandwidth allocation algorithm for supporting QoS in IEEE 802.11e WLANs with Hybrid Coordination Function (HCF) access method. It distributes the limited WLAN capacity by taking into account the desired queueing delay that multimedia data flows would expect. The algorithm has been designed by following a control theoretic approach and its properties have been analy...
