background the development of an effective subunit vaccine against brucellosis is a research area of intense. but optimization of recombinant proteins production in escherichia coli and content of endotoxins associated with final recombinant proteins are very important. objectives in the present study, expression and purification of brucella melitensis rhsp and rtf were optimized to reduce endo...

Nowadays, we are witnesses of 5G mobile technology advancements and many countries plan to or already have introduced this public usage. However, the older technologies such as 3G, HSPA 4G LTE, because their physical properties, ways datagram transfers frequency bands used, still very suitable for usage in cases that assume longer distances between terminal device cell towers. Having mind, a re...

It is a universally stated design requirement that next generation mobile systems will be compatible and interoperable with IPv6 and with various access technologies such as IEEE 802.11x. Discussion in the literature is currently as to whether the recently developed High Speed Packet Access (HSPA) or the developing Long Term Evaluation (LTE) technology is appropriate for the next generation mob...

This paper analyzes latency in a High-Speed Packet Access network appropriately resourced for emulated Machine-to-Machine and Online Gaming traffic. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are used for conveying application data and the measurement results from the end-user perspective are compared. In TCP case, traffic traces were recorded in two points of the core...

TCP has been the dominant transport protocol for mobile internet since its origin. Its behaviors play an essential role in determining quality of service/experience (QoS and QoE) for mobile apps. While TCP has been extensively studied in a static, walking, or driving mobility, it has not been well explored in highspeed (> 200 km/h) mobility cases. With increasing investment and deployment of hi...
