Abstract Background For a long time, for patients with WHO grade 3 glioma the gold-standard after surgical treatment has been radiotherapy (RT). Since combined radio-chemotherapy became standard as postoperative therapy glioblastoma in 2005, role of temozolomide (RT/TMZ) controversial. Evidence is growing that RT/TMZ provides advantages progression-free survival (PFS) and overall (OS) gliomas w...

To analyze the relationship between costs and utility units obtained by the patients in this scenario. PATIENTS AND METHODS This economic evaluation was performed during a clinical trial with a 48-week followup in a ...

Recently, the IEEE 802.16 standard (IEEE Std 802.16-2004, 2004), a solution to broadband wireless access commonly known as Worldwide Interoperability for Microwave Access (WiMAX), has been considered as a promising standard for next generation broadband wireless access networks. IEEE 802.16e (IEEE Std 802.16e-2005, 2005), also called Mobile WiMAX (Li et al., 2007), provides enhancements to IEEE...

Recently, there have been numerous standardization activities for making the IEEE802.16e system highly effective in supporting mobile users based on orthogonal frequency division multiple access (OFDMA) with Time Division Duplex (TDD) mode in (IEEE Standard 802.16e-2005, 2005) and (WiMAX Forum). Standardization activities of the IEEE802.16e system were completed in 2005, and currently enhanceme...

The sensory ecology of predator detection by prey has been little studied for any arthropod prey predator system, in contrast to the sensory ecology of prey finding by predators. The aim of this study was to quantify the foraging signals produced by the parasitoid Sympiesis sericeicornis (Hymenoptera: Eulophidae) and the sensory ecology of enemy detection and the avoidance behaviour of the leaf...

These IT-enabled processes and businesses however depend on secure information systems which need to be managed. The management of information systems security (ISS) is a highly dynamic and complex task due to constant change in the information technology domain. In this ...

Remote operations are commonly employed in oil and gas installations in the North Sea and elsewhere. The use of information and communications technologies (ICT) has resulted in process control systems being connected to corporate networks as well as the Internet. In addition, multiple companies, functioning as a virtual organization, are involved in operations and management. The increased con...
