The experiment was performed with a non-aqueous binary two-phase solvent system composed of n-heptane and acetonitrile. The CCC column was first filled with the upper stationary phase, and then a large volume of water sample was pumped into the column while the CCC column was rotated at 1600 rpm. Finally, the trace amounts of PAHs extracted and enriched in the stationary phase were eluted out by the lower mobile phase and determined by gas chromatography-flame ionization detector (GC-FID) or gas chromatography-mass spectrometry (GC-MS). The enrichment and cleanup of PAHs can be fulfilled online by this method with high recoveries (84.1-103.2%) and good reproducibility (RSDs: 4.9-12.2%) for 16 EPA PAHs under the optimized CCC pretreatment conditions. This method has been successfully applied to determine PAHs in lake water where 8 PAHs were detected in the concentration of 40.9-89.9 ng/L. The present method is extremely suitable for the preparation of large volume of environmental water sample for the determination of trace amounts of organic pollutants including PAHs as studied in this paper.

The first is the analysis of the leak reflected wave during a transient event and the second is inverse transient analysis (ITA). This was approached through the development of an inverse transient analysis tool and the collection of transient data for the testing and validation of this model. Two experimental programmes were carried out at Imperial College and in cooperation with Thames Water for the validation and testing of these techniques. Evaluation of the presence, location and size of leaks was carried out using the collected data. Transient-based techniques have been shown to be successful in the detection and location of leaks and leak location uncertainties depended on the leak size and location, flow regime and location where the transient event was generated. These leak detection methods are very promising for identifying the general area of the trunk main with leakage, and can be combined with other leak location techniques (e.g. acoustic equipment) to more precisely pinpoint the leak position. Transient-based techniques are particularly important for the diagnosis, monitoring and control of existing water supply systems, not only to detect leaks, but also to better understand the causes of pipe bursts and accidents, particularly when these are due to natural transient events.

In this approach, a polyethylene Pasteur squeeze-type pipette was employed as a convenient extraction device and ultrasound radiation was applied to accelerate the emulsification of low-density organic solvent in aqueous solutions to enhance the microextraction efficiency of OCPs in water samples. Thirty microliters of extraction solvent (isooctane), of lower density than water, were injected into the aqueous sample solution held in the pipette. The latter was then immersed in an ultrasound water bath to form an emulsion. After 30s extraction, phase separation was achieved by centrifugation. The upper layer (isooctane) was collected and analyzed by GC-MS. No disperser solvent was required in this procedure. Significantly, fast analysis and high extraction efficiency were achieved. Another feature of the procedure was the use of the pipette as the extraction device, which permitted less dense than water organic solvent to be used as extraction solvent. This method broadens the applicability of USAEME to a wider range of solvent. Additionally, carry-over problems were avoided with the use of the disposable pipette. Parameters affecting the efficiency of polyethylene Pasteur pipette-based USAEME, such as the extraction solvent, extraction solvent volume, extraction and centrifugation time, ionic strength and extraction temperature were investigated. Under the optimum conditions, the proposed method provided good enrichment factors (EFs) in the range of 128 and 328, with relative standard deviations (RSDs) ranging from 2.7% to 12.4%. The limits of detection were in the range of 0.8 and 10ng/L depending on the analytes. The linearities were between 0.01 and 50mug/L for hexachlorobenzene, dieldrin, endrin and o,p'-DDD, 0.05-25mug/L for heptachlor, and 0.005-50mug/L for p,p'-DDE. Finally, the polyethylene Pasteur pipette-based USAEME was successfully used for the fast determination of OCPs in river and tap water samples. The proposed method provides a simple, convenient, rapid, sensitive, cost-effective, and environmentally friendly process for the determination of OCPs in water samples.

This could lead to muscle dysfunction and thus to impairments of exercise and quality of life (QOL). Considering the impressive number of WP smokers, we intend to investigate the potential effect of WPS on submaximal exercise capacity and QOL. AIMS: (1). To evaluate the submaximal exercise capacity by the 6-minutes walking test (6-MWT). (2). To compare the deficiency, incapacity and QOL data of exclusive WPS with those of two control groups (never smokers and exclusive cigarette smokers). (3). To determine the factors influencing the 6-minutes walk distance (6-MWD) of WPS subjects. METHODS: A multicentre study including 180 exclusive WPS > or =5 WP-year] men aged > or =40 years. Cigar or cigarette smoking, contraindications to the 6-MWT or cortico-steroid therapy will be exclusion criteria. QOL evaluation, spirometry, electrocardiogram and two 6-MWT will be performed. Signs of exercise impairment will be: 6-MWD or =5/10, haemoglobin saturation fall > or =5 points. Data from WPS subjects will be compared with those from 90 never smoking subjects and 90 exclusives cigarettes smokers. EXPECTED RESULTS: (1). WPS will affect significantly the submaximal exercise capacity. (2). Resting spirometric, 6-MWT and QOL data of exclusive WPS subjects will be significantly reduced compared to never smoking subjects. (3). The 6-MWD's of exclusive WPS subjects will be significantly influenced by cumulative WP consumption, by resting spirometric data, by obesity and by physical activity score.

METHODS: Three studies were descriptive and one used a pretest-posttest design. From four Pilot Focus groups (N = 28 smokers) key tobacco use themes emerged along with information on study measures and the Project TNT intervention; Pilot Intervention tested the tailored Project TNT intervention with 9 Arab-American teens; Pilot Clinic (N = 44) determined the characteristics of the accessible teen health clinic population; and Pilot School (N = 119) obtained tobacco use data only. RESULTS: From Pilot Focus seven themes (being cool, "nshar ma'a al shabab" [hanging out with the guys], present [time] orientation, smoking feels and tastes good, keeps your mind off trouble, easy to get, and (many) "barriers to quitting") emerged from the data. In the Pilot Intervention a 37.5% cessation rate was found. In the Pilot Clinic study, 24% males and 17% females smoked. The current smoking rate in the Pilot School (N = 119) sample was 17%; 34% admitted to having ever smoked (even a puff). Significant predictors for current tobacco use included poor grades, stress, having many family members and peers who smoke, being exposed to many hours of smoking each day, receiving offers of tobacco products, advertising and mail, and believing that tobacco can help one to make friends. CONCLUSIONS: The four pilots contributed unique and essential knowledge for designing a longitudinal clinical trial on tobacco use by Arab-American adolescents.

METHODS: Evaluations of the in vitro growth kinetics, influences by saliva and serum, and sensitivity to antifungal agents of Candida biofilm were performed with the abated tetrazolium salt XTT method on a 96-well microtire petri dish. The ultrastructure of Candida biofilm was observed under Confocal Laser Scanning Microscope (CLSM). RESULTS: The bioactivity of Candida biofilm increased with culturing time and serum could obviously increase the action of biofilm. The Candida biofilm was significantly resistant to routine antifungal agents. CONCLUSION: The Candida cells adhered in biofilms are significantly different in morphology from those in suspension and are resistant to routine antifungal agents such as Amphotericine B, Fluconazole and Itraconazole.

METHODS: Anonymous questionnaires were distributed to PHC providers in 7 randomly selected PHC centers in Aleppo, Syria. RESULTS: All PHC providers completed the questionnaires (100% response rate). A quarter of these providers smoke cigarettes and more than 10% smoke waterpipes. Physicians who smoke were less likely to advise patients to quit (OR=0.29; 95% CI, 0.09-0.95), assess their motivation to quit (OR=0.13, 95% CI=0.02-0.72), or assist them in quitting (OR=0.24, 95% CI=0.06-0.99). PHC providers who smoke were less likely to support a ban on smoking in PHC settings (68.2% vs. 89.1%) and in enclosed public places (68.2% vs. 86.1%) or increases in the price of tobacco products (43.2% vs. 77.4%) (P<0.01 for all comparisons). CONCLUSIONS: Smoking, including waterpipe, continues to be widespread among PHC providers in Syria and will negatively influence implementation of anti-smoking program in PHC settings. PRACTICE IMPLICATIONS: Smoking awareness and cessation interventions targeted to PHC providers, and training programs to build providers' competency in addressing their patients' smoking is crucial in Syria.

Examining smoking behaviors among occupational groups with a high prevalence of women may reveal the culture of smoking behavior and quit efforts of female smokers. The purpose of this study was to examine how smoking and quitting characteristics (i.e., ever and recent quit attempts) among females in the occupation of nursing are similar or different to those of women in the general population. METHODS: Cross-sectional data from the Tobacco Use Supplement of the Current Population Survey 2006/2007 were used to compare smoking behaviors of nurses (n = 2, 566) to those of non-healthcare professional women (n = 93, 717). Smoking characteristics included years of smoking, number of cigarettes, and time to first cigarette with smoking within the first 30 minutes as an indicator of nicotine dependence.
