ONE of the major problems associated with the disinfection of water supplies by chlorination is that the organoleptic properties of the chlorinated water may be increased. This malodorous water is often produced by a reaction between the added chlorine and trace concentrations of organic compounds present in the water. By far the most notorious of the organic compounds found in water which incr...

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-...

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...

Novel LaOCl/LaCl3 catalysts have been discovered that enable the production of vinyl chloride monomer from ethane. An ethane-based process would result in both capital savings and raw materials savings when compared to the current most effective vinyl technology. These materials are unique in the world of chlorination/oxychlorination as the mechanism for chlorination over LaOCl/LaCl3 occurs on ...

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...

BACKGROUND Haemophilus influenzae serotype b (Hib) has yet to be eliminated despite the implementation of routine infant immunization programs. There is no consensus regarding the number of primary vaccine doses and an optimal schedule for the booster dose. We sought to evaluate the effect of a booster dose after receiving the primary series on the long-term disease incidence. METHODS A stoch...
