Economical, eco-friendly, future ready and sustainable livestock production to meet ever growing human population is a daunting task for the animal farming community including scientist. Additionally making effort develop strategies or chain of combact global warming through manipulating ruminants another challenge in era alarming situation. Among causes warming, animals particularly are one ma...

The standard 802.11 presents a Medium Access Control (MAC) anomaly when stations with different data rates operate at the same Access Point. This paper presents a strategy for using SNR to control the contention window and consequently mitigate the anomaly. Simulations using Network Simulators (NS) are presented to demonstrate the anomaly and to evaluate the mitigation anomaly strategy. The str...

this research chiefly focused on the application of mitigation strategies and traditional form of feedback in writing development of the fifth semester university students majoring in tefl and english translation fields based on vygotsky’s sociocultural theory in general and the notion of “zone of proximal development” in particular. to that end, this study relied on a pre-posttest experimental...

background:  ramsar, a northern city in iran, lies on the coast of the caspian sea. this city has areas with some of the highest levels of natural radiation measured to date. the radon concentration in some areas of ramsar is up to 3700 bq m–3. on the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this city....

Variable message sign (VMS) is an effective traffic management tool for congestion mitigation. The VMS is primarily used as a means of providing factual travel information or genuine route guidance to travelers. However, this may be rendered sub-optimal on a network level by potential network paradoxes and lack of consideration for its cascading effect on the rest of the network. This paper foc...

This study investigates the efficacy of optimal semi-active dampers for achieving the best results in seismic response mitigation of adjacent buildings connected to each other by magnetorheological (MR) dampers under earthquakes. One of the challenges in the application of this study is to develop an effective optimal control strategy that can fully utilize the capabilities of the MR dampers. H...
