infection by m. tuberculosis can be demonstrated by tuberculin testing. on sequential ppd some person show a marked increase in the size of their skin reactions which may not be due to recent or past tuberculous infection. this phenomenon (booster effect) can occur as soon as a week after the initial test and persist for as long as a year. methods and materials: the purpose of this research is ...
The ALBA Booster is a synchrotron designed to accelerate electron beams from 100 MeV to 3GeV in a 3Hz cycle. The maximum pulse coming from the ALBA Linac provides 5 mA in the Booster. In order to check all the Booster sub-systems, a Booster pre-commissioning took place during two weeks in January 2010. This paper presents the Diagnostics elements installed in the ALBA Booster and our experience...
OBJECTIVES Latino children are more likely to be unrestrained passengers in motor vehicles than non-Latino children, but little is known about the use of booster seats in Latino families. This study investigates Latino parents' knowledge, attitudes and beliefs about booster seats, barriers to booster seat use, and effective strategies for message delivery in the Latino community. METHODS Two ...
This study used telephone interview data on booster seat use from a state-wide probability sample of parents with children ages 4-8-years-old who were living in Michigan. Interviews were completed with parents of children in 350 households. Analyses examined the entire sample, and three sub-groups: always users, part-time booster seat users, and booster seat non-users. Results indicated that bo...
The current study explored the benefits of adding booster sessions to a validated and successful self-management intervention for type 2 diabetes patients (i.e. Beyond Good Intentions). Although the addition of booster sessions to self-management interventions is often recommended, it has not been empirically established to what extent booster sessions are in fact appreciated by participants. P...
The aim of the current study is to estimate the epidemiological and economical consequences of several extended pertussis booster vaccination strategies and to explore the impact of parameters surrounded by large uncertainty on the cost-effectiveness. We developed an age structured transmission dynamic model to evaluate the impact of programs targeting (i) adolescents or adults using a single b...
This paper proposes an effective numerical methodology to analyze the mechanism of the separation of an inserted type of solid rocket booster from a supersonic air breathing engine vehicle having a conical intake. Unlike the previous computational fluid dynamic (CFD) approach, present work constructs a compacted model capable to reduce the computational time definitely. The dynamics of vehicle ...
The SPEAR2 accelerator system originally had 3 RF stations (2 for storage ring, 1 Booster) operating at 358.5 MHz. SPEAR3 now operates at 476.3 MHz with the PEPII type RF system, while the Booster RF frequency remains unchanged. For top-off operation, the Booster injects single 3.0 GeV electron bunches into SPEAR3 at 10 Hz every 5 minutes to replenish lost charge. Due to the frequency mismatch ...
UNLABELLED Here we report the first evaluation of T-cell responses upon a second acellular pertussis booster vaccination in Dutch children at 9 years of age, 5 years after a preschool booster vaccination. Blood samples of children 9 years of age were studied longitudinally until 1 year after the second aP booster and compared with those after the first aP booster in children 4 and 6 years of ag...
OBJECTIVE To describe several aspects of booster seat use and misuse in a sample of children attending child safety seat clinics. METHODS Booster seat practices were assessed at 76 child safety seat clinics held between April 1997 and January 1999 in Pennsylvania and southern New Jersey. At each assessment, a child passenger safety team evaluated the booster seat and identified modes of misus...
