Abstract
A review, originally carried out for Sydney Water Corporation, of a complete range of direct and indirect methodologies used to assess the condition of buried cast iron and steel water pipelines is presented. These techniques include pipe sampling, pit depth measurement, soil testing using various parameters, as well as other non-destructive testing (NDT) based on various electromagnetic principles. Both the literature and comprehensive field trials have shown that soil testing using linear polarisation resistance (LPR) methodologies as an input to statistical analysis packages is a cost-effective technique. Direct evaluation using remote field eddy current intelligent pigs can also be very useful for the direct examination of critical watermains but is limited to smaller sizes of DN 150-DN 375.

Abstract
Sensations derived from initial exposure to nicotine are a potential indicator of an individual's vulnerability to nicotine. This study assessed whether sensations experienced during the first lifetime exposure to nicotine could predict current and established cigarette smoking. Data from 210 respondents who reported having ever tried cigarette smoking in Wuhan, China, were obtained for this study from 610 students in 10th grade at two schools. Subjects were participants in a multipurpose pilot survey for an adolescent smoking prevention trial. The survey was administered in a classroom setting using a paper-and-pencil questionnaire. Sensations reported were cigarette smell (59.2%), coughing (54.1%), dizziness (52.1%), nausea (42.5%), relaxation (19.1%), and pleasurable buzz/rush (9.0%). After controlling for confounders, multiple logistic regression analyses identified three sensations significantly associated with smoking: (a) Cigarette smell (OR for days smoked in the past 30 days=2.93, p<.05, OR for number of cigarettes smoked per day=2.69, p<.05, and OR for 100-cigarette smoking=5.40, p<.01), (b) pleasurable buzz/rush (OR for 100-cigarette smoking=11.09, p<.05), and (c) relaxation (OR for past 30-day smoking measures ranged from 3.69 to 4.48, p<.01, and OR for 100-cigarette smoking=4.12, p<.05). A dose-response relationship was observed between the sensations and cigarette smoking. Self-reported sensations from initial exposure to nicotine may be a useful indicator of an individual's vulnerability to nicotine. This information can be used for adolescent smoking prevention and cessation interventions.

Abstract
Ribosomal DNA-based techniques including the analysis of profiles generated by ISR amplification, ISR restriction and ARDRA have been evaluated as molecular tools for identifying Carnobacterium, Lactobacillus, Leuconostoc and Pediococcus. They have been applied for the molecular characterization of 91 strains with the following identities: eight Carnobacterium including the eight type species of the genus; 61 Lactobacillus including 40 type strains out of 45 species, 13 Leuconostoc, out of them 11 are type strains and three are subspecies of Lc. mesenteroides; and nine strains representing the six species of genus Pediococcus. The genetic relationship displayed between these species by rrn-based profiles is sustained by their phylogenetic relationships and can therefore be considered useful for taxonomic purposes. Profiles obtained by ISR amplification allowed identification at genus level of Carnobacterium and Leuconostoc, and even at species level in genus Carnobacterium. Genera Lactobacillus and Pediococcus could not be distinguished from each other by applying this technique. The Lactobacillus species analysed here (45) were differentiated using ARDRA-DdeI and ISR-DdeI profiles, sequentially, and Pediococcus species by ISR-DdeI profiles. It was necessary to combine profiles generated by restriction of ISR-DdeI, ARDRA-DdeI and ARDRA-HaeIII in order to complete the identification of Leuconostoc species.

Abstract
Three analogous laboratory-scale water pipe systems were constructed to study the effects of three chlorine levels of finished water on the growth of biofilm. The experimental results indicated that the heterotrophic plate counts (HPCs) of biofilm for chlorine-free water were approximately 2 and 3 orders of magnitude higher than those for low-chlorine water (0.3-0.5 mg/l Cl2) and high-chlorine water (1.2-1.5 mg/l Cl2), respectively. The difference in HPCs between low-chlorine water and high-chlorine water was below 1 order. Average biofilm formation rates are 325 ATP pg/cm2 per day for chlorine-free water, 159 ATP pg/cm2 per day for low-chlorine water and 118 ATP pg/cm2 per day for high-chlorine water. Scanning electron microscope (SEM) observation showed that bacterial species separated from the biofilm were more complex than from the finished water. The Gram-negative bacteria were dominant.

Abstract
STATEMENT OF PROBLEM: The use of bonding agents in the luting procedure for porcelain laminate restorations to enamel is not clear. PURPOSE: This study evaluated the shear bond strength differences between an enamel-luting composite and a heat-pressed ceramic with 6 different bonding systems. MATERIAL AND METHODS: Seventy standardized heat-pressed IPS Empress ceramic discs (4-mm diameter, 3-mm height) were prepared. A vertical planar enamel-bonding surface was prepared on the buccal or lingual enamel of 70 freshly extracted sound human molars and premolars. The teeth were oriented to maintain a parallel relationship between the bonding plane and the shear loading axis of a universal testing machine. Tooth specimens were divided into 7 groups (n=10) comprising equal numbers of molars and premolars. The enamel surfaces of specimens in groups 1 through 6 were prepared with 1 of 6 bonding agents (Scotchbond Multi Purpose Plus, Heliobond, PQ1, SE Bond, Prime&Bond NT, and Prompt L-Pop). Finally, the specimens were luted to the ceramic discs with the composite cement (Opal Luting Composite). Ceramic discs in the seventh group (Control) were luted to the etched enamel with the composite cement without using bonding material. Enamel-ceramic specimens were kept in distilled water at room temperature for 30 days after cementation. All specimens were shear loaded axially in a universal testing machine with a crosshead speed of 0.05 mm/min until fracture. Shear bond strength was measured and recorded for each group in MPa. To determine the statistical significance of the differences between the mean shear bond strength values, a 1-way analysis of variance was used (alpha=.05). Post-hoc multiple comparisons were made with Duncan's multiple range analysis. Fractured surfaces of each specimen were also inspected with a stereomicroscope to evaluate failure modes. RESULTS: A 1-way analysis of variance revealed significant differences between the test groups (P=.00). Bond strength values (MPa) from the highest to the lowest were as follows: Prompt L-Pop, 25.46 +/- 5.6; Prime&Bond NT, 18.99 +/- 4.93; Heliobond, 17.28 +/- 4.0; SE Bond, 16.21 +/- 2.6; PQ1, 15.60 +/- 2.8; Scotchbond MPP, 14.82 +/- 2.4; and Control, 10.55 +/- 1.6. Duncan's multiple range post hoc analysis exhibited significant differences between the control group and the adhesive bonding agent groups (P<.05). There were also significant differences between the bonding agent groups (P<.05). Prompt L-Pop showed the highest bond strength values. CONCLUSION: Within the limitations of this study, bonding agents appear to have a strengthening effect on the shear bond strengths of the enamel/composite/porcelain interface of the materials tested. Bonding agents used in this study showed similar bond strength values except for Prompt L-Pop, which demonstrated the highest bond strength values.

Abstract
As the major transporters and distributors of water and minerals, xylem vessels and tracheids are the lifeline of plants. Interestingly, the building blocks of these water pipes are dead tracheary elements and vessel elements that have the process of cell death integrated into their differentiation programme. Using the Zinnia in vitro model system for xylogenesis, a key nuclease that is responsible for nuclear degradation during the terminal stages of tracheary element differentiation has been identified recently.

Abstract
Pozol is an acid beverage obtained from the natural fermentation of nixtamal (heat- and alkali-treated maize) dough. The concentration of mono- and disaccharides from maize is reduced during nixtamalization, so that starch is the main carbohydrate available for lactic acid fermentation. In order to provide some basis to understand the role of amylolytic lactic acid bacteria (ALAB) in this fermented food, their diversity and physiological characteristics were determined. Forty amylolytic strains were characterized by phenotypic and molecular taxonomic methods. Four different biotypes were distinguished via ribotyping; Streptococcus bovis strains were found to be predominant. Streptococcus macedonicus, Lactococcus lactis, and Enterococcus sulfureus strains were also identified. S. bovis strain 25124 showed extremely low amylase yield relative to biomass (139 U g [cell dry weight](-1)) and specific rate of amylase production (130.7 U g [cell dry weight](-1) h(-1)). In contrast, it showed a high specific growth rate (0.94 h(-1)) and an efficient energy conversion yield to bacterial cell biomass (0.31 g of biomass g of substrate(-1)). These would confer on the strain a competitive advantage and are the possible reasons for its dominance. Transient accumulation of maltooligosaccharides during fermentation could presumably serve as energy sources for nonamylolytic species in pozol fermentation. This would explain the observed diversity and the dominance of nonamylolytic lactic acid bacteria at the end of fermentation. These results are the first step to understanding the importance of ALAB during pozol fermentation.

Abstract
Barrett's esophagus is a metaplastic condition that occurs in patients with gastroesophageal reflux disease (GERD) and its importance lies in its potential to develop adenocarcinoma of the esophagus. The diagnosis of Barrett's esophagus is based on finding of intestinal metaplasia of at least 3 cm of the distal esophagus. The diagnosis of intestinal metaplasia of less than 3 cm of the distal esophagus is controversial, regarding implications with GERD, adenocarcinoma, and Helicobacter pylori. The aims of the study were to determine the prevalence of intestinal metaplasia in the distal esophagus in patients with short segments of esophageal columnar-appearing mucosa (less than 3 cm), diagnosed endoscopically, in two groups of patients, with and without symptoms of GERD. In total, 97 patients were examined, with endoscopic finding of esophageal columnar-appearing mucosa less than 3 cm. From the total, 52 patients had symptoms of GERD and 45 patients were without these symptoms. These patients were subjected to distal esophageal biopsies obtained immediately below the epithelial transition. The biopsies were stained with hematoxylin-eosin and alcian blue at pH 2.5. Urease test for H. pylori detection in two fragments of gastric antrum was carried out. The presence of intestinal metaplasia in the distal esophagus was diagnosed in 16 (30.8%) patients in the GERD group and 12 (26.7%) patients without GERD symptoms. No statistical differences were observed (P = 0.82; 95% CI: 0.61-2.17). The variables sex, mean age and positivity for H. pylori did not show statistical differences. This study diagnosed high prevalence of intestinal metaplasia in the distal esophagus with columnar-appearing mucosa, less than 3 cm, with no statistical differences in the two groups studied with and without GERD symptoms.

Abstract
A total of 161 low-G+C-content gram-positive bacteria isolated from whole-crop paddy rice silage were classified and subjected to phenotypic and genetic analyses. Based on morphological and biochemical characters, these presumptive lactic acid bacterium (LAB) isolates were divided into 10 groups that included members of the genera Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, and WEISSELLA: Analysis of the 16S ribosomal DNA (rDNA) was used to confirm the presence of the predominant groups indicated by phenotypic analysis and to determine the phylogenetic affiliation of representative strains. The virtually complete 16S rRNA gene was PCR amplified and sequenced. The sequences from the various LAB isolates showed high degrees of similarity to those of the GenBank reference strains (between 98.7 and 99.8%). Phylogenetic trees based on the 16S rDNA sequence displayed high consistency, with nodes supported by high bootstrap values. With the exception of one species, the genetic data was in agreement with the phenotypic identification. The prevalent LAB, predominantly homofermentative (66%), consisted of Lactobacillus plantarum (24%), Lactococcus lactis (22%), Leuconostoc pseudomesenteroides (20%), Pediococcus acidilactici (11%), Lactobacillus brevis (11%), Enterococcus faecalis (7%), Weissella kimchii (3%), and Pediococcus pentosaceus (2%). The present study, the first to fully document rice-associated LAB, showed a very diverse community of LAB with a relatively high number of species involved in the fermentation process of paddy rice silage. The comprehensive 16S rDNA-based approach to describing LAB community structure was valuable in revealing the large diversity of bacteria inhabiting paddy rice silage and enabling the future design of appropriate inoculants aimed at improving its fermentation quality.

Abstract
A cross sectional study was carried out in two rural secondary schools in Qualyobia governorate in the academic year 2002-2003 in order to assess the students' knowledge, attitudes and practice toward smoking. An anonymous self-administered questionnaire was used. A total of 635 students, 416 males and 219 females were interviewed. The response rate was 100%. The prevalence of ever tried cigarette was 29% (40% among males and 7% among females) with a median age of initiation at 11 years of age. The prevalence of current cigarette smoking among all students was 7.7 (11.5% among males and 0% among females). Waterpipe (Shisha) smoking was reported by 19% (26% among males and 5% among females) with median age of initiation at 12 yearsof age. The risk of smoking is higher among sons of highly educated mothers (OR=3.7, 95% CI=1-12), Boy only school students have almost half the risk of smoking than mixed school male students (OR=0.4, 95% CI=0.2-0.8). On studying the effect of having a smoker family member or friends on students smoking, having a smoker friend increases the risk of male students three time (OR=3, 95%CI=2-5) while others smoking was not statistically significant. More than 90% of the students (both males and females) thought that active and passive smoking are harmful. More females than males thought smoking is addictive (89% of the females and 81% of the males) while more males than females agreed that smokers have more friends (34% of males, 26% of the females) and that smoking makes boys look handsome (8% of males, 3% of females).
