OBJECTIVE Belt-positioning booster seats have been shown to reduce injury risk among child passengers aged 4 to 8 in motor vehicle crashes. To encourage the use of booster seats, many states have enacted laws that require the use of either a child restraint with internal harness or a belt-positioning booster seat, but the specific age range covered by the laws varies by state. Previous studies ...

To examine the influence of a pertussis booster vaccination on the transfer of maternal antibodies, 24 nonpregnant women received a tetanus, diphtheria, acellular pertussis booster vaccine between 2 consecutive pregnancies. Blood was drawn from mothers and off-spring. Efficient transplacental antibody transfer and significantly higher antibody titers against 3 pertussis antigens were observed i...

OBJECTIVE Cognitive-behavioral therapy (CBT) is effective for adult ADHD, and booster sessions may improve long-term outcome. This study was designed to investigate the effects of group CBT and its booster sessions for Chinese adult patients with ADHD. METHOD There were CBT only group ( n = 43), CBT +booster group ( n = 43), and control group with patients on the waiting list ( n = 22). The p...

In this paper we present a project of a Booster-injector for the Duke FEL storage ring. The Booster will provide full energy injection into the storage ring at energy from 0.25 to 1.2 GeV. The Duke storage ring FEL (SR FEL) operates in lasing mode with 193-700 nm wavelength range [1,2]. This range will be extended into VUV in near future [3,4]. The geometry of the Duke SR FEL provides for head-...

compared to conventional chlorination methods which apply chlorine at water treatment plant, booster chlorination has almost solved the problems of high dosages of chlorine residuals near water sources and lack of chlorine residuals in the remote points of a water distribution system (wds). however, control of trihalomethane (thm) formation as a potentially carcinogenic disinfection by-product ...

BACKGROUND The pandemic potential of avian influenza A/H5N1 should not be overlooked, and the continued development of vaccines against these highly pathogenic viruses is a public health priority. METHODS This open-label extension booster study followed a Phase III study of 1206 adults who had received two 3.75 μg doses of primary AS03A-adjuvanted or non-adjuvanted H5N1 split-virus vaccine (A...

OBJECTIVE To determine the prevalence of booster seat misuse in a Canadian province and identify determinants of non-use. METHODS A cross-sectional study using parking lot interviews and in-vehicle restraint inspections by trained staff was conducted at 67 randomly selected childcare centres across Alberta. Only booster-eligible children were included in this analysis. Odds ratios (OR) and 95...

Optimisation of the Diamond Light Source injector has continued since user operation started in January 2007. Beam losses have been minimised by injector tuning and stabilisation, and high level software has been developed to characterise booster and injection parameters. Operation in top-up and single bunch storage ring fill modes are reported, and low-energy linac fault-mode studies are detai...

OBJECTIVES Motor vehicle injury is the leading cause of injury death for children 4 to 8 years of age. Although booster seat use in this age group substantially reduces the risk of injury, most children are currently restrained by seatbelts designed for adults. The objective of this study was to measure booster seat use directly, determine factors predictive of proper child restraint, and asses...

OBJECTIVE To compare child care center-based booster seat education and distribution with no intervention when implemented immediately after booster seat legislation. DESIGN Cluster randomized controlled trial. SETTING Thirty-nine urban child care centers. PARTICIPANTS Eight hundred fifty-four parents and 1010 children aged 4 to 8 years in vehicles leaving centers. Intervention We trained...
