Change Is Brewing: The Industrialization of the London Beer-Brewing Trade, 1400-1750

London\u27s early modern brewing trade was a dynamic one that was constantly in flux throughout the fifteenth, sixteenth, seventeenth, and eighteenth centuries. This dissertation seeks to better understand how issues of gender, ethnicity, and class changed and shaped London\u27s early modern brewing industry. Women played a vital role in the production and marketing of ale in London\u27s medieval brewing trade. They were displaced from that position of prominence through the introduction of hops by foreign immigrants, known to strangers to their hosts, and the desire of the City of London to more closely regulate the trade in ale and beer. Those forces combined to marginalize women in the trade as they were replaced by male strangers brewing beer. Those strangers came to control the late fifteenth and early sixteenth century brewing trade. Their product, beer, was superior to English ale in durability and cost less to produce. As London began to transition from an ale-drinking community to a beer-drinking one, the community of beer-brewing strangers came under attack on several fronts. Their guild, the Beer Brewers chartered in 1493, was consolidated within Ale Brewers\u27 Guild in 1556 and in 1573 the now native-dominated guild issued an order banning strangers from the guild for ten years. Following shortly on the heels of that order, the City of London banned strangers from becoming members of London\u27s guilds and, by extension, from joining London\u27s leadership. Together the Brewers\u27 Company and the City limited opportunities for strangers, which would lead to the trade becoming dominated by natives by 1600. Native brewers had cut out many of their competitors by 1600, but were vulnerable to other threats. The greatest threat to their existence across the seventeenth and early eighteenth century was taxation by the English state. Although an attempt to tax the industry failed in 1637, an excise tax on beer was introduced in 1643 and became the backbone of government excise revenues throughout the next two centuries. London brewers were forced to adapt to the excise. Some became quite successful, expanding their breweries and influence in local and national politics. Most, however, found that the extra burden of the excise made investing in the expansion of their breweries impossible. This situation became acute following the revolution of 1688-89 as the English state demanded ever more through the excise. Those demands exacerbated already existing tensions between smaller and larger brewers in the London community, which came to a head in the early eighteenth century as many smaller brewers were forced from the trade and their share of the market gobbled up by their larger competitors. Following the introduction of porter, a beer suited to industrialized production, to London around 1720, the last piece of the puzzle for the rise of the great industrial brewers, such as the Calverts and Thrales, was in place. What had been a trade that was once dominated by marginalized populations in the form of women and strangers was now controlled by an industrialized elite

Ant colony optimization for agile motion planning

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2006.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 67-69).With the need for greater autonomy in unmanned vehicles growing, design of algorithms for mission-level planning becomes essential. The general field of motion planning for unmanned vehicles falls into this category. Of particular interest is the case of operating in hostile environments with unknown threat locations. When a threat appears, a replan must be quickly formulated and executed. The use of terrain masking to hide from the threat is a vital tactic, which a good algorithm should exploit. In addition, the algorithm should be able to accommodate large search spaces and non-linear objective functions. This thesis investigates the suitability of the Ant Colony Optimization (ACO) heuristic for the agile vehicle motion planning problem. An ACO implementation tailored to the motion planning problem was designed and tested against an existing genetic algorithm solution method for validation. Results show that ACO is indeed a viable option for real-time trajectory generation. ACO' ability to incorporate heuristic information, and its method of solution construction, make it better suited to motion planning problems than existing methods.by Tom Krenzke.S.M

Glossitis in an older non-corgi dog: Diagnosis and long-term follow-up.

A 9-year-old spayed female 18.8 kg mixed breed boxer dog was referred for evaluation of a 7-month history of difficulty swallowing and prehending food, regurgitation, hypersalivation, and an abnormal dorsiflexion of the tongue. Prior to referral, a barium study was performed, which revealed a mildly dilated esophagus. Treatment with sucralfate, cisapride, and prednisone was initiated. Physical examination revealed bilateral, symmetric atrophy of the temporalis muscles, dorsiflexion of the distal aspect of the tongue with concurrent muscle atrophy, and a reduced gag reflex. Electrodiagnostic examinations revealed spontaneous electrical activity in the muscles of mastication and tongue. Biopsies from the right temporalis, tongue, and biceps femoris muscles were collected. An immune-mediated myositis with fibrosis, scattered CD3, CD4, and CD8+ T-lymphocytes, and upregulation of markers for major histocompatibility antigens were observed in the tongue and temporalis muscles. The dog was treated with a tapering course of prednisone over 2 months and cyclosporine long-term. The dog was maintained on cyclosporine alone for > 2 years and clinical signs remained static, although multiple episodes of aspiration pneumonia occurred. Ultimately, euthanasia was performed due to chronic kidney disease with associated anemia, lethargy, and anorexia

Tratamento para re?so da ?gua de lavagem de animais do frigor?fico Frigobuti? do Munic?pio de S?o Pedro do Buti?

Currently, with the water shortages, it is sensitive to concern and the search for procedures to reuse it safely, for the environment and especially for health. In the industries the area of effluent treatment is ample with the purpose of reusing it again in its production process. Thus, the objective of this study was to construct a Slow Pilot Filter, monitor its operation and evaluate the feasibility of implementing a real-scale Lentoem Filter for the treatment of animal washing waters from the Frigo Buti? located in the city of S?o Pedro do Buti? RS , in order to demonstrate that sustainable practices can be utilized seeking benefits for the industrial sectors, as well as for society and the environment. Daily analyzes were performed for the parameters of turbidity, pH, true color, conductivity and total and thermotolerant coliforms, and scraped the filter bed at the end of each filtration run. The filter removed up to 96% turbidity, up to 94.7% apparent color, conductivity was reduced up to 68%, and the pH remained between 7 and 8 at a temperature of 23 to 27 ? C. The removal of coliforms was up to 100% of thermotolerant coliforms and removal of up to 98% of total coliforms. This study shows that it is possible to install the Slow Filter in the FrigoButi? to clean the corrals, pens, corridors, cleaning trucks and other environments where water with a drinking quality standard is not required.Atualmente com a escassez das ?guas, ? sens?vel a preocupa??o e a busca por procedimentos para reutiliz?-la de forma segura, para o ambiente e principalmente para a sa?de.

Catalytic Upgrading of Biomass Model Compounds: Novel Approaches and Lessons Learnt from Traditional Hydrodeoxygenation – a Review

Catalytic hydrodeoxygenation (HDO) is a fundamental process for bio‐resources upgrading to produce transportation fuels or added value chemicals. The bottleneck of this technology to be implemented at commercial scale is its dependence on high pressure hydrogen, an expensive resource which utilization also poses safety concerns. In this scenario, the development of hydrogen‐free alternatives to facilitate oxygen removal in biomass derived compounds is a major challenge for catalysis science but at the same time it could revolutionize biomass processing technologies. In this review we have analysed several novel approaches, including catalytic transfer hydrogenation (CTH), combined reforming and hydrodeoxygenation, metal hydrolysis and subsequent hydrodeoxygenation along with non‐thermal plasma (NTP) to avoid the supply of external H2. The knowledge accumulated from traditional HDO sets the grounds for catalysts and processes development among the hydrogen alternatives. In this sense, mechanistic aspects for HDO and the proposed alternatives are carefully analysed in this work. Biomass model compounds are selected aiming to provide an in‐depth description of the different processes and stablish solid correlations catalysts composition‐catalytic performance which can be further extrapolated to more complex biomass feedstocks. Moreover, the current challenges and research trends of novel hydrodeoxygenation strategies are also presented aiming to spark inspiration among the broad community of scientists working towards a low carbon society where bio‐resources will play a major role.Financial support for this work was provided by the Department of Chemical and Process Engineering of the University of Surrey and the EPSRC grants EP/J020184/2 and EP/R512904/1 as well as the Royal Society Research Grant RSGR1180353.
