Tandem enzyme-catalysed reduction/cis-dihydroxylation of 2,2,2-trifluoroacetophenone: chemoenzymatic routes to new enantiopure phenol and benzylic alcohol reagents

Factors that control the competition between toluene dioxgenase-catalysed arene cis-dihydroxylation and dehydrogenase-catalysed ketone reduction have been studied, using whole cells of Pseudomonas putida UV and three alkylaryl ketones. The triol metabolite, obtained from 2,2,2-trifluoroacetophenone, has been used in the synthesis of single enantiomer chiral phenols and benzylic alcohols. Potential applications of the methylether derivatives of the chiral phenols and benzylic alcohols, as resolving agents, have been found. (c) 2007 Society of Chemical Industry.

Coating of Cotton Yarn with Poly(vinyl alcohol) and Poly(N-vinyl-2-pyrrolidone) Crosslinked via Ultraviolet Radiation

The coating of cotton fiber is used in the textile industry to increase the mechanical resistance of the yarn and their resistance to vibration, friction, impact, and elongation, which are some of the forces to which the yarn is subjected during the weaving process. The main objective of this study was to investigate the use of synthetic hydrophilic polymers, poly(vinyl alcohol) (PVA), and poly(N-vinyl-2-pyrrolidone) (PVP) to coat 100% cotton textile fiber, with the aim of giving the fiber temporary mechanical resistance. For the fixation of the polymer on the fiber, UV-C radiation was used as the crosslinking process. The influence of the crosslinking process was determined through tensile testing of the coated fibers. The results indicated that UV-C radiation increased the mechanical resistance of the yarn coated with PVP by up to 44% and the yarn coated with PVA by up to 67% compared with the pure cotton yarn, that is, without polymeric coating and crosslinking. This study is of great relevance, and it is important to consider that UV-C radiation dispenses with the use of chemical substances and prevents the generation of toxic waste at the end of the process.

Gambling and corporate social responsibility (CSR) : re-defining industry and state roles on duty of care, host responsibility and risk management

During the 1990s, states embraced legalised gambling as a means of supplementing state revenue. But gaming machines (EGMs, pokies, VLTs, Slots) have become increasingly controversial in countries such as Australia, Canada and New Zealand, which experienced unprecedented roll-out of gaming machines in casino and community settings; alongside revenue windfalls for both governments and the gambling industry. Governments have recognised that gambling results in a range of social and economic harms and, similar to tobacco and alcohol, have introduced public policies predicated on harm minimisation. Yet despite these, gaming losses have continued to climb in most jurisdictions, along with concerns about gambling-related harms. The first part of this article discusses an emerging debate in Ontario Canada, that draws parallels between host responsibility in alcohol and gambling venues. In Canada, where government owns and operates the gaming industry, this debate prompts important questions on the role of the state, duty of care and regulation ‘in the public interest’ and on CSR, host responsibility and consumer protection. This prompts the question: Do governments owe a duty of care to gamblers?

The article then discusses three domains of accumulating research evidence to inform questions raised in the Ontario debate: evidence that visible behavioural indicators can be used with high confidence to identify problem gamblers on-site in venues as they gamble; new systems using player tracking and loyalty data that can provide management with high precision identification of problem gamblers and associated risk (for protective interventions); and research on technological design features of new generation gaming products in interaction with players, that shows how EGM machines can be the site for monitoring/protecting players. We then canvass some leading international jurisdictions on gambling policy CSR and consumer protection.

In light of this new research, we ask whether the risk of legal liability poses a tipping point for more interventionist public policy responses by both the state and industry. This includes a proactive role for the state in re-regulating the gambling industry/products; instituting new forms of gaming machine product control/protection; and reinforcing corporate social responsibility (CSR) and host responsibility obligations on gambling providers – beyond self-regulatory codes. We argue the ground is shifting, there is new evidence to inform public policy and government regulation and there are new pressures on gambling providers and regulators to avail themselves of the new technology – or risk litigation

Does cigarette promotion increase susceptibility to smoking? : a re-test of the link between tobacco industry promotion and adolescent susceptibility to cigarette use

In 1998, using the Index of Receptivity to Tobacco Industry Promotion (IRTIP), it was claimed that tobacco promotion increased youth susceptibility to smoking. Arguably, this claim started the belief that ?cigarette advertising causes smoking? and led to many countries severely restricting cigarette promotion. The problem is, ten years lat... more »er, youth are still lighting up. Could they have gotten it wrong? The IRTIP procedure is widely used to model the link between promotional activities and susceptibility to product use. It is now being used for other products like alcohol, fast-food and colas. This book reports the results of a verification and re-test of the IRTIP model. Using the original data, it was found that IRTIP magnifies Response-Style and Respondent Drop-Out Biases. These biases are shown to lead to the finding of a positive link between tobacco promotion and susceptibility to smoking. Because the IRTIP process is biased, it may be prudent to revisit the many research studies that have used this procedure. The faulty 1998 claim may have harmed efforts to control and limit the use of cigarettes.

Dealing with alcohol-related problems in the night-time economy: a study protocol for mapping trends in harm and stakeholder views surrounding local community level interventions

This project will provide a comprehensive investigation into the prevalence of alcohol-related harms and community attitudes in the context of community-based interventions being implemented to reduce harm in two regional centres of Australia. While considerable experimentation and innovation to address these harms has occurred in both Geelong and Newcastle, only limited ad-hoc documentation and analysis has been conducted on changes in the prevalence of harm as a consequence, leaving a considerable gap in terms of a systematic, evidence-based analysis of changes in harm over time and the need for further intervention. Similarly, little evidence has been reported regarding the views of key stakeholder groups, industry, government agencies, patrons or community regarding the need for, and the acceptability of, interventions to reduce harms. This project will aim to provide evidence regarding the impact and acceptability of local initiatives aimed at reducing alcohol-related harms.

Gambling advocacy: lessons from tobacco, alcohol and junk food

OBJECTIVE: To explore the attitudes and opinions of public health experts in gambling and related unhealthy commodity industries towards the tactics used by the gambling industry to prevent reform and the advocacy responses to these tactics. METHODS: In-depth interviews (30-60 minutes) with a convenience sample of 15 public health experts and stakeholders with a public health approach to gambling (n=10), or other unhealthy commodity industries (food, alcohol, tobacco, n=5). RESULTS: Participants described the influences of political lobbying and donations on public policy, and industry framing of problem gambling as an issue of personal responsibility. Industry funding of, and influence over, academic research was considered to be one of the most effective industry tactics to resist reform. Participants felt there was a need to build stronger coalitions and collaborations between independent academics, and to improve the utilisation of media to more effectively shift perceptions of gambling harm away from the individual and towards the product. CONCLUSIONS AND IMPLICATIONS: Gambling industry tactics are similar to the tactics of other unhealthy commodity industries. However, advocacy initiatives to counter these tactics in gambling are less developed than in other areas. The formation of national public health coalitions, as well as a strong evidence base regarding industry tactics, will help to strengthen advocacy initiatives.

Improving the implementation of responsible alcohol management practices by community sporting clubs: A randomised controlled trial

INTRODUCTION AND AIMS: Despite an increased prevalence of risky alcohol consumption and alcohol-related harm among members of sporting groups and at sporting venues, sporting clubs frequently fail to implement alcohol management practices consistent with liquor legislation and best practice guidelines. The aim of this study was to assess the impact of a multi-strategy intervention in improving the implementation of responsible alcohol management practices by sports clubs. DESIGN AND METHODS: A randomised controlled trial was conducted with 87 football clubs, with half randomised to receive a multi-strategy intervention to support clubs to implement responsible alcohol management practices. The 2-year intervention, which was based on implementation and capacity building theory and frameworks, included project officer support, funding, accreditation rewards, printed resources, observational audit feedback, newsletters, training and support from state sporting organisations. Interviews were undertaken with club presidents at baseline and post-intervention to assess alcohol management practice implementation. RESULTS: Post-intervention, 88% of intervention clubs reported implementing '13 or more' of 16 responsible alcohol management practices, which was significantly greater than the proportion of control groups reporting this level of implementation (65%) [odds ratio: 3.7 (95% confidence interval: 1.1-13.2); P = 0.04]. All intervention components were considered highly useful and three-quarters or more of clubs rated the amount of implementation support to be sufficient. DISCUSSION AND CONCLUSIONS: The multi-strategy intervention was successful in improving alcohol management practices in community sports clubs. Further research is required to better understand implementation barriers and to assess the long-term sustainability of the change in club alcohol management practices.

Analysis of the performance of an extraction-condensation steam turbine on a cogeneration system of a Brazilian sugar-alcohol factory

In this work a detailed thermodynamic analysis for an extraction-condensation steam turbine capable to drive a 40 MVA electricity generator in a sugar-alcohol factory was carried out. The use of this turbine in the cogeneration system showed that its efficiency contributed to increase the power generation, although the condensation reduces the overall efficiency of the plant. Sensibility analyses were performed to evaluate the behavior of the overall energy efficiency of a plant with the extraction-condensation turbine in function of the boiler efficiency, the specific consumption of steam in the processes and the condensation rate in the turbine. It was observed that the plant efficiency is very sensible to the condensation rate variation and it increases when there is an increase in the demand of steam for processes.

Economical analysis of ethanol steam reformer for hydrogen production associated with a sugarcane industry

An expressive amount of produced hydrogen is generated by customers in-situ such as petrochemical, fertilizer and sugarcane industries. However, the most utilized feedstock is natural gas, a non-renewable and fossil fuel. The introduction of biohydrogen production process associated in a sugarcane industry is an alternative to diminish emissions and contribute to create a CO2 cycle, where the plants capture this gas by photosynthesis process and produces sucrose for ethanol production. The cost of production of ethanol has dramatically decreased (from about US$ 700/m3 in 1970s to US$ 200/m3 today), becoming this a good option at near term, inclusively for its utilization by customers localized in main regions (localized especially in regions such as Southeastern Brazil) Also in near future, it will possible the utilization of fuel cells as form of distributed generation. Its utilization could occur specially in peak hours, diminishing the cost of investments in newer transmission systems. A technical and economic analysis of steam reformer of ethanol to hydrogen production associated with sugarcane industry was recently performed. This technique will also allow the use of ethanol when its price is relatively low. This study was based on a previous R&D study (sponsored by CEMIG - State of Minas Gerais Electricity Company) where thermodynamic and economic analyses were developed, based in the development of two ethanol steam reformers prototypes.x In this study an analysis was performed considering the use of bagasse as source of heat in the steam reforming process. Its use could to diminish the costs of hydrogen production, especially at large scale, obtaining cost-competitive production and permitting that sugarcane industry produces hydrogen in large scale beyond ethylic alcohol, anhydrous alcohol (or ethanol) and sugar.

Structural Alterations of Lignins in Transgenic Poplars with Depressed Cinnamyl Alcohol Dehydrogenase or Caffeic Acid O-Methyltransferase Activity Have an Opposite Impact on the Efficiency of Industrial Kraft Pulping1

We evaluated lignin profiles and pulping performances of 2-year-old transgenic poplar (Populus tremula × Populus alba) lines severely altered in the expression of caffeic acid/5-hydroxyferulic acid O-methyltransferase (COMT) or cinnamyl alcohol dehydrogenase (CAD). Transgenic poplars with CAD or COMT antisense constructs showed growth similar to control trees. CAD down-regulated poplars displayed a red coloration mainly in the outer xylem. A 90% lower COMT activity did not change lignin content but dramatically increased the frequency of guaiacyl units and resistant biphenyl linkages in lignin. This alteration severely lowered the efficiency of kraft pulping. The Klason lignin level of CAD-transformed poplars was slightly lower than that of the control. Whereas CAD down-regulation did not change the frequency of labile ether bonds or guaiacyl units in lignin, it increased the proportion of syringaldehyde and diarylpropane structures and, more importantly with regard to kraft pulping, of free phenolic groups in lignin. In the most depressed line, ASCAD21, a substantially higher content in free phenolic units facilitated lignin solubilization and fragmentation during kraft pulping. These results point the way to genetic modification of lignin structure to improve wood quality for the pulp industry.
