Abstract
Large-scale transitions in societies are associated with both individual behavioural change and restructuring of the social network. These two factors have often been considered independently, yet recent advances in social network research challenge this view. Here we show that common features of societal marginalization and clustering emerge naturally during transitions in a co-evolutionary adaptive network model. This is achieved by explicitly considering the interplay between individual interaction and a dynamic network structure in behavioural selection. We exemplify this mechanism by simulating how smoking behaviour and the network structure get reconfigured by changing social norms. Our results are consistent with empirical findings: The prevalence of smoking was reduced, remaining smokers were preferentially connected among each other and formed increasingly marginalized clusters. We propose that self-amplifying feedbacks between individual behaviour and dynamic restructuring of the network are main drivers of the transition. This generative mechanism for co-evolution of individual behaviour and social network structure may apply to a wide range of examples beyond smoking.

Abstract
A novel solid-phase microextraction (SPME) fiber based on carbon nanotubes-titanium oxide (CNT-TiO2) composite coating bonded onto stainless steel wire was prepared via electroless plating and sol-gel techniques. The SPME coating was characterized by scanning electron microscopy and Raman microscopy. Coupled to gas chromatography (GC), the fiber was investigated with seven polycyclic aromatic hydrocarbons (PAHs) in direct-immersion mode. The SPME-GC analytical method was evaluated under optimized extraction conditions. Compared with other reports, higher sensitivity (LODs, 0.002-0.004 mug L(-1)) and better linear range (0.01-100 and 0.01-200 mug L(-1)) were obtained by the proposed method. The fiber exhibited high thermal stability to 300 degrees C and excellent durability in HCl and NaOH solutions. The as-established SPME-GC method was used to analyze the real water samples and satisfactory results were obtained.

Abstract
It is reported that more than 75% of 400 artisanal fisherman divers working off the Yucatan Peninsula experience decompression sickness (DCS) each year, making DCS an epidemic in this region. These divers use primitive hookah diving support systems (HDSS). Breathing air is supplied from inadequately filtered and poorly maintained gasoline-powered air compressors. We hypothesized that air supplies could be contaminated. Air contamination could produce symptoms consistent with some presentations of DCS. This could confound and falsely elevate the true incidence of DCS. A cross-sectional study was undertaken in a fishing community. Ten fishermen from a single cohort participated. Fishermen were instructed not to drain volume tanks following their last dive of the day before their diving air was sampled. Drager carbon monoxide (CO) 5/a-P and carbon dioxide (CO2) 100/a Short-term Tubes were used to measure 1.0 liters (L) of gas through a Visi-Float flow meter at 0.2 L/minute. Average CO value was 42 ppm (8-150 ppm). Average CO2 was 663 ppm (600-800). Measurements exceeded recommended diving norms for CO of 20 ppm. CO2 exceeded one diving organization recommendation of 500 ppm. Separation of engine exhaust from compressor intake could decrease CO values in HDSS to acceptable standards thus eliminating one possible confounder from this DCS epidemic.

Abstract
INTRODUCTION: Waterpipe tobacco smoking involves self-administration of the dependence-producing drug nicotine. Few studies have examined if dependence in waterpipe smokers influences toxicant exposure and smoking behavior. METHOD: Current waterpipe tobacco smokers were categorized based on Lebanese Waterpipe Dependence Scale-11 (LWDS-11) score (LWDS-11: LOW 13; N = 59). Participants abstained from smoking for 12 hr and then completed a single 30-min waterpipe tobacco smoking episode. Expired-air carbon monoxide (CO) was measured before and 5 min after smoking and puff topography was measured during smoking. RESULTS: Total mean smoking time was 30.9 min (SD = 3.5) and did not differ significantly by LWDS-11 score. CO boost was greater for participants in the HIGH versus LOW groups (62.3 vs. 43.6 ppm, p

Abstract
INTRODUCTION: Waterpipe tobacco smoking is increasing in popularity though the toxicant exposure and effects associated with this tobacco use method are not well understood. METHODS: Sixty-one waterpipe tobacco smokers (56 males; mean age +/- SD, 30.9 +/- 9.5 years; mean number of weekly waterpipe smoking episodes, 7.8 +/- 5.7; mean duration of waterpipe smoking 8.5 +/- 6.1 years) abstained from smoking for at least 24 hr and then smoked tobacco from a waterpipe ad libitum in a laboratory. Before and after smoking, expired-air carbon monoxide (CO) and subjective effects were assessed; puff topography was measured during smoking. RESULTS: The mean waterpipe use episode duration was 33.1 +/- 13.1 min. Expired-air CO increased significantly from a mean of 4.0 +/- 1.7 before to 35.5 +/- 32.7 after smoking. On average, participants took 169 +/- 100 puffs, with a mean puff volume of 511 +/- 333 ml. Urge to smoke, restlessness, craving, and other tobacco abstinence symptoms were reduced significantly after smoking, while ratings of dizzy, lightheaded, and other direct effects of nicotine increased. DISCUSSION: Expired-air CO and puff topography data indicate that, relative to a single cigarette, a single waterpipe tobacco smoking episode is associated with greater smoke exposure. Abstinent waterpipe tobacco smokers report symptoms similar to those reported by abstinent cigarette smokers, and these symptoms are reduced by subsequent waterpipe tobacco smoking. Taken together, these data are consistent with the notion that waterpipe tobacco smoking is likely associated with the risk of tobacco/nicotine dependence.

Abstract
A total of 320 potable water samples were collected from various rural and urban sources located in the Lublin region of eastern Poland. They comprised: 55 samples of treated (chlorinated) tap water from rural dwellings distributed by the municipal water supply system (MWSS), 111 samples of treated tap water from urban dwellings distributed by the MWSS, 45 samples of untreated well water from household wells and 109 samples from private water supply systems (PWSS) distributing untreated well water. Water samples were examined for the presence and species composition of Legionella, Yersinia, Gram-negative bacteria belonging to family Enterobacteriaceae (GNB-E) and Gram-negative bacteria not belonging to the family Enterobacteriaceae (GNB-NE), by filtering through cellulose filters and culture on respectively GVPC, CIN, EMB and tryptic soya agar media. The occurrence of Legionella in the samples taken from the outlets of the urban MWSS was high (77.5%), and significantly greater compared to frequencies noted in rural MWSS (7.3%), and samples of well water from household wells (28.9%) and PWSS (13.8%) (p

Abstract
After 1990 a gradual privatisation of the water and sewerage sector began in the Czech Republic as well as in other Central and Eastern European countries. State assets of public water pipelines and sewerage were transferred to towns and municipalities and joint stock companies were established. Two types of companies appeared-operational and ownership companies. The first type is the operational company that operates the infrastructure assets of public water pipelines and sewerage. These assets stay in the ownership of municipalities. A long term operational contract is agreed that solves the relationship between the owners and operators. The second type is the ownership company that directly owns the infrastructure assets of public water pipelines. Towns and municipalities in this case became shareholders of those companies. At the end of nineties, big international companies bought shares of both operational and ownership companies. Municipalities have to, by law, ensure the operation of public water pipelines. However, by the sale of shares they have lost a possibility to participate in decision making. A question about future co-operation between towns and municipalities and ownership companies appears. An example of the North Moravian Water and Sewerage Works Company was used to describe a possible way of co-operation between a private company and the municipalities on whose territory the company operates. Contracts between the ownership company and particular municipalities were agreed. This solution turned out to be complicated, so the municipalities affiliated and established Water Management Association. The objective of the Association is to promote common interests of the municipalities in relation to the water company. A contract was agreed between the Water Management Association and the company about co-operation in the area of water tariff setting and public waterworks' development.

Abstract
In the present study, we determined the molecular epidemiology of extended-spectrum beta-lactamases (ESBLs) in Escherichia coli isolated from diseased farmed pigeons in China. A total of 71 E. coli isolates were collected from three pigeon farms from 2011 to 2012 and screened for the presence of the ESBL genes. The ESBLs producers were further tested for the presence of PMQR-encoding genes as well as the 16S rRNA methylase gene using PCR and DNA sequence analysis. Co-transfer of plasmids encoding for ESBLs, PMQR determinants and/or 16S rRNA methylase gene was performed by conjugation into E. coli. The genetic relatedness and plasmid replicon type were determined. A total of 41 ESBLs producers were identified. Only CTX-M type ESBLs were detected, with the most common CTX-M types being CTX-M-65 (n=17), CTX-M-27 (n=11), CTX-M-55 (n=10). Thirty-eight CTX-M-positive isolates were found to harbor at least one PMQR gene, with aac(6')-Ib-cr (n=32) and oqxAB (n=21) being the most prevalent. The rmtB was the only prevalent 16S rRNA methylase gene detected in 24 (58.1%) CTX-M-positive isolates. Although most of the CTX-M producers had distinct pulsotypes, clonal transmission in the same farm was observed. blaCTX-M genes were carried by IncF alone or in combination with IncK plasmids with three different sizes, including 76.8Kb (n=20), 194Kb (n=5), 104.5Kb (n=2). PFGE profiles of CTX-M-positive E. coli isolates indicated potential horizontal spread of these multidrug resistant strains along with those CTX-M encoding genes. Our findings highlight the importance of pigeons as a reservoir of multiple antimicrobial resistance genes.

Abstract
Vapors were once thought to be exhalations of body organs (such as the stomach), which affected the physical and mental state of a person. Early American pioneers frequently blamed almost any muscle ache, pain or fever on 'the vapors.' Mental depression, hysterical nervous conditions and other psychological illnesses were all attributed to the elusive vapors. It seemed logical that to cure maladies caused by the exhalation of vapors one simply inhaled medicinal agents in the form of gases or fumes. In so doing, the American pioneers were repeating a form of traditional medicine that is as old as humanity itself. The history of vapors and their curative powers can be traced to both Old and New World practices. In the Old World, the ancient Sumerians, Egyptians and Greeks, among others, employed the vapors of marijuana, opium and carbon dioxide. In the New World, early South and North Americans burned tobacco and coca. Nearly everywhere these practices spread, local cultures embellished the vapors with their own plant drugs. Three such practices remain today: the smoking of tobacco, opium and coca. The Spaniards introduced tobacco smoking to the Philippine Islands from where it spread to China at the beginning of the seventeenth century. The Chinese, finding the tobacco somewhat unpleasant, mixed various substances with it including arsenic, marijuana and opium. The Persians, also finding it unpleasant, passed the smoke through water and developed early versions of water pipes. By the end of the seventeenth century, tobacco dipped in opium was commonly used in Java. This custom spread to Formosa and then back to China. Gradually, the Chinese faded out the tobacco and began smoking opium alone and this practice became widespread by the end of the eighteenth century. The Chinese refined the opium preparations and a concentrated paste of crude opium became the preferred form. The paste was heated and the smoke or vapors were inhaled. Enormous doses were sometimes smoked, doses that would produce certain death if taken orally or by a nontolerant user (Kane 1882). Since those early beginnings, opium has captured the romantic imagination, bodies and minds of people across the planet. Yet, as historian A.R. Neligan (1927: 34) points out, opium takes a far tighter hold of an individual than all other drugs except cocaine. Cocaine vapors shared a similar association with tobacco smoking in its South American genesis. The magico-religious uses of tobacco burning and smoking, the sacrificial burning of coca leaves, the inhalations of tobacco smoke to cure disease, the medicinal inhalation of vapors from burning coca seeds, and the chewing of mixtures of tobacco and coca leaves were all common events in the early history of that area. Eventually a crude coca paste was mixed with tobacco and smoked. As the practice spread to North America, the tobacco was gradually eliminated. Innovative pioneer alchemists in the United States in the twentieth century have refined the coca paste into a purified alkaloid more suitable for smoking. Called cocaine free base, the product is heated in water pipes and the smoke or vapors are inhaled. Like the opium vapors, enormous doses of cocaine are sometimes inhaled: doses that have produced lethal effects when administered via other routes. The resultant practice of cocaine smoking has become a new fad. But smoking vapors of cocaine is like the phantasms the word 'vapors' suggests: a foolish and fanciful, albeit fashionable, notion. It may also lead to a potentially toxic and dependence-producing disorder. THE COCAINE SMOKING DISORDER: The major findings of this monograph present evidence for a new substance mental disorder, the Cocaine Smoking Disorder. The diagnostic criteria for this disorder are: A. Recent use of cocaine via smoking of the free base (or coca paste). B. At least two of the following psychological symptoms within less than one hour of smoking cocaine: 1. psychomotor agitatio

Abstract
This study is part of a wider project aiming to correlate the chemical composition of the coffee volatile fraction to its sensory properties with the end-goal of developing an instrumental analysis approach complementary to human sensory profiling. The proposed investigation strategy compares the chemical information concerning coffee aroma and flavor obtained with HS-SPME of the ground coffee and in-solution SBSE/SPME sampling combined with GC-MS to evaluate their compatibility with the cupping evaluation for quality control purposes. Roasted coffee samples with specific sensory properties were analyzed. The chemical results obtained by the three samplings were compared through multivariate analysis, and related to the samples' sensory attributes. Despite the differences between the three sampling approaches, data processing showed that the three methods provide the same kind of chemical information useful for sample discrimination, and that they could be used interchangeably to sample the coffee aroma and flavor.
