Relating Methanogen Community Structure to Function in Anaerobic Wastewater Digesters

Anaerobic wastewater treatment is an environmentally and economically beneficial biotechnology in which the degradation of organic compounds in industrial and municipal wastewaters results in the production of methane, an alternative energy source. The degradation of organic waste is carried out by an interdependent microbial community; and the Archaea known as the methanogens complete one of the final steps, producing methane. However, the contribution of methanogens and the community ecology of anaerobic digesters are just beginning to be understood. Specifically, links between methanogen community structure and the successful transformation of organic pollutants to methane have not been clearly defined. In order to examine the relationship between anaerobic digester function and methanogen community structure, anaerobic biomass samples were obtained from anaerobic hydrogen/carbon dioxide enrichment cultures, lab-scale anaerobic digesters, and industrial-scale digesters. DNA and cDNA clone libraries using the methanogen-specific gene mcrA were generated from the enrichment cultures and two industrial digester samples, and quantitative polymerase chain reaction (qPCR) was used to quantify the mcrA genes and transcripts in all of the biomass samples. Phylogenetic analysis of the mcrA sequences found in the clone libraries showed differences in the methanogen communities from different anaerobic biomass samples, even from enrichment cultures started with the same seed sludge. Furthermore, comparison of mcrA genes and transcripts from the enrichment cultures revealed that some methanogens were more active than others. However, no direct links were found between methanogen diversity and digester function. Tandem qPCR and specific methanogenic activity (SMA) assays showed positive correlation between mcrA gene copy number and methane production rates against specific substrates. This result indicates a relationship between the number of methanogens and digester function. Positive correlation was determined between mcrA transcript number and SMA only under certain conditions. This study represents the establishment of a direct link between the microbial community in anaerobic biomass and digester function. The data obtained from these studies provides a better understanding of methanogen communities in digesters which can be applied to develop better assays for monitoring the function of anaerobic biomass, and to engineer better microbial communities that produce more methane for use as renewable fuel

228— Biden\u27s Bounce: The African American Vote and Biden\u27s South Carolina Comeback

On February 29, 2020, registered Democrats across South Carolina came out to vote for their preferred primary candidate. At the time of this primary, former Vice President Joe Biden needed a win to show that he was still a contender in the race. As the poles closed that night, it was clear that South Carolina was going to give Biden the win and this momentum eventually propelled his campaign to a bigger win on Super Tuesday. South Carolina is an important primary state with 63 delegates available, and it can make or break a candidate’s chance of securing the nomination. It is important to win over one of the most important groups in the Democratic party in South Carolina, which are the African American voters. African Americans make up 27% of the state\u27s population and with a majority of African Americans being registered democrats, getting their votes can mean the difference between winning and losing. African American voters in South Carolina are an important part of the primary process and looking at where they live and how they voted in the election is an important part of analyzing Joe Biden’s big win

Emotionalism within furniture design

This thesis explores the question: What are the significant emotional connections between consumers and their furniture, and how do designers engage with this? Due to the nature of the question it has been necessary to explore literature across various different faculties. Therefore the literature review covers a wide spectrum of research and methodologies exploring the significance of the psychological factors (especially emotions) in the designing and consuming of furniture. This has enabled the author to identify the main factors within the thesis; design, the consumer and emotions each are discussed in detail. The relationships and connections between each are also investigated. The research also identified that due to the various types on furniture available, only one could be evaluated for this thesis; therefore the branch of furniture studied is chairs. Using the research carried out, a methodology was created in order to carry out a practical exploratory chair study. This involved identifying five categories of chairs, and selecting one from each, and then staging a suitable environment to carry out the trial. Participants were then asked to interact with each chair, whilst at the same time answering an in-depth verbal questionnaire. The purpose of the trial was to establish if each of the chairs evoked any emotional connections to the participants and if so what types of emotion. The results of the trial were then analysed, from which conclusions were able to be deduced and a consequence of the study was discussed

Framing of Press Releases

Framing of Press Releases: A Heartbeat Bill Study. This paper focuses on the impact of framing and the Spiral of Silence theory on media companies press releases. The press releases studied are related to the topic of the recent passing of the Heartbeat Bill in Georgia on May 7, 2019. Through thematic analysis, constructs and themes are collected from the press releases. Through the use of Hallahan’s model of framing and Corporate Social Responsibility (CSR) factors, we are able to find similar frames in the press releases. These constructs seek to reinforce a pattern consistent with the Spiral of Silence theory’s themes of opinion climate, hardcore and non-hardcore individuals and the fear of isolation

Barium titanate: photophysics, photocatalysis & the influence of the ferroelectric effect

Photocatalytic and photoelectrochemical water splitting processes remain hindered by fast recombination of photogenerated electrons and holes. Ferroelectric materials are increasingly being considered to address this issue; their internal electric fields have been shown to spatially separate electrons and holes, and thus should greatly reduce recombination rates. A kinetic understanding of the extent to which electron–hole recombination can be slowed in ferroelectric materials is essential to ascertain if they can play a significant role in achieving higher solar-driven water splitting efficiencies. The focus of this thesis is an experimental investigation of charge carrier dynamics in barium titanate (BaTiO3) to observe the effect of internal electric fields on recombination rates. Time-resolved spectroscopic techniques were used in conjunction with photocatalysis studies to determine whether ferroelectricity can significantly reduce recombination rates and lead to enhanced performance. It is found that, although the transient absorption spectrum of ferroelectric BaTiO3 is similar to previously reported metal oxides, the carrier lifetimes are significantly longer, indicating the potential for ferroelectrics to be used in devices limited by fast electron–hole recombination. In the first results chapter, the transient absorption spectrum of single crystal BaTiO3 is characterised under inert atmosphere over two timescales: femtosecond–nanosecond and microsecond–second. Absorption signals due to photogenerated holes and electrons are identified using electron and hole scavengers, respectively. Comparisons are drawn between BaTiO3 and other single crystal, but non-ferroelectric, metal oxides. It is found that, on timescales relevant for water oxidation, lifetimes in BaTiO3 are at least an order of magnitude longer. In the second results chapter, the origin of long carrier lifetimes in ferroelectric BaTiO3 is explored. When the polarisation is switched off by both temperature and nanostructuring, carrier lifetimes decrease by four orders of magnitude. Recombination rates in BaTiO3 exhibit a much stronger temperature dependence than other metal oxides, which is rationalised by considering the temperature dependence of the spontaneous polarisation. The third results chapter investigates the photocatalytic performance of BaTiO3 nanopowders. It is found that, in the presence of an electron scavenger, BaTiO3 photogenerated holes are reactive and can oxidise water to produce oxygen. Transient and photoinduced absorption spectroscopies indicated that hole accumulation in a BaTiO3 sample with a higher tetragonal (ferroelectric) content, which translates to higher rates of oxygen evolution. The final results chapter probes the influence of a ferroelectric BaTiO3 substrate on α-Fe2O3 thin films. Preliminary data suggests the internal field can penetrate through the film and slow electron–hole recombination rates in α-Fe2O3.Open Acces
