In some statistical process control applications, quality of a process or product can be characterized by a relationship between a response and one or more independent variables, which is typically referred to a profile. In this paper, polynomial profiles are considered to monitor processes in which there is a first order autoregressive relation between the error terms in each profile. A remedi...

background: considering the lack of data available on changes of physical activity over time in iran, this study was designed to evaluate changes in physical activity levels among iranian adults over a median 6.5 yr period. methods: in this population-based cohort study, 3515 participants, aged ≥ 20 yr (2100 females and 1415 males) were followed from phase ii (2002-2005) to phase iv (2008-2011)...

we conducted this study to determine the risk of transmission of q fever to health care workers (hcws) during perioperative exposure to coxiella burnetii -infected thoracic endovascular aneurysm stent graft. pre-operative and 6-week post-operative phase i and ii igg q fever antibody titers were determined in 14 staff members of an operation room. the room had a negative pressure and all the mem...

a simple, rapid and sensitive solvent assisted-dispersive solid phase extraction method was developed for the extraction of iron(ii) prior to its spectrophotometric determination. the fe(ii) reacted with 2,4,6-tris(2-pyridyl)-1,3,5-triazine, neutralized with sodium dodecyl sulfate and extracted onto the fine particles of benzophenone which were formed upon rapid injection of a mixture of benzop...

Wireless spectrum is becoming a vital and scarce resource due to the increase development and deployment of mobile device and their associated applications. Dynamic Spectrum Access (DSA) represents one of the few ways that our nation can be able cope with our anticipated spectrum crisis1. Wireless communications is a key tool in today’s economy and efficient use of this spectrum is paramount. I...

background: the haplotype phasing is more useful than genotyping markers independently at carrier detection and prena­tal diagnosis of diseases. the pah gene region contains several markers used in detection of pku disease. in the present study, the efficiency of bgl ii- ecor i-vntr haplotype phasing in iranian family trios was investigated. then, this informa­tion was compared with those obtai...

As the use of molecularly targeted agents, which are anticipated to increase overall survival (OS)and progression-free survival (PFS) but not necessarily tumor response, has increased in oncology, there has been a corresponding increase in the recommendation and use of randomized phase II designs. Such designs reduce the potential for bias, existent in comparisons with historical controls, but ...
