GENDER TRANSITION AS SELF-REALISATION IN LATER LIFE: Interview with a 72 year old Trans woman in Wales

Trans experiences of ageing have, so far, been minimally explored in academic literature; however, older Trans people who have transitioned in later life have much to offer the fields of both Trans Studies and Cultural Gerontology. By drawing on an interview with Jenny-Anne Bishop, a 72-year-old Trans woman, this study suggests that Trans ageing experiences are not adequately accounted for by dominant cultural narratives of ageing, notably decline and age-defying narratives, and instead proposes Laceulle and Baars’ (2014) framework of self-realisation as a suitable alternative. Concurrently, this study serves as an empirical illustration of how self-realisation as a framework for meaning attribution in later life can be applied

Strategies for Improving Efficiency and Emissions in Heavy-Duty Diesel Engines

This study presents an experimental investigation of the novel combination of a “wave" bowl piston with thermal barrier coatings (TBCs) and Miller cycle intake valve strategies. All experiments were carried out with a single cylinder research engine with fully-flexible valve timing capabilities. The results indicate the wave bowl geometry enables this combination to improve fuel consumption, steady-state engine-out NOₓ emissions, and particulate matter (PM) emissions, improving the NOₓ-PM tradeoff that compromises diesel engine efficiency. These benefits were achieved at the expense of elevated turbocharger efficiency requirements. Three TBCs of varying composition and thickness were tested at seven operating conditions of varying speed and load. TBC performance was highly dependent on volumetric efficiency (VE), as cases with reduced VE increased the heat transfer gradient between the combustion gasses and the combustion chamber. The insulative properties of each TBC determined the impact of the aforementioned change in the heat transfer gradient, with the most pronounced effects on fuel conversion efficiency, up to a 0.6% increase, observed at medium and high load operation. The soot oxidation impacts of the wave piston were diminished at higher engine speeds, with the lowest PM emission increases for the TBC cases with reduced VE observed at the low speed conditions. Early Intake Valve Closing (EIVC) and Late Intake Valve Closing (LIVC) Miller cycle strategies were compared to a conventional intake valve profile at a low speed-medium load condition under constant engine-out NOₓ emissions. The reduction in effective compression ratio from using Miller cycle was symmetric around bottom dead center, while EIVC profiles were more effective at reducing VE than LIVC profiles. The implementation of an overall turbocharger efficiency metric clarified the source of discrepancies found in the current body of work on Miller cycle, as studies reporting fuel consumption penalties were typically underutilizing boost capabilities and those reporting significant efficiency improvements were exceeding boost capabilities. Miller cycle profiles yielded 0.5% BSFC and 30% PM emission increases at the baseline turbocharger efficiency. Those penalties were nullified with an 8% relative increase in turbocharger efficiency. The combined TBC-Miller cycle study compared extreme Miller cycle strategies to a conventional intake valve profile at a low speed-medium load operating point under high boost conditions. Comparisons were made under fixed cylinder composition, engine-out NOx emissions, and turbocharger efficiency constraints. Miller cycle at fixed cylinder composition demonstrated that LIVC strategies effectively reduced heat transfer losses, elevated exhaust losses, and reduced engine-out NOₓ emissions by up to 35%. Extreme LIVC timings increased fuel consumption by 3% because increased exhaust losses exceeded the reduced heat transfer losses. Miller cycle strategies enabled increased charge dilution at the fixed NOₓ constraint, improving fuel consumption by 1.3% over the baseline without compromising exhaust temperatures. This study produced the novel insight that varying EGR rates for NOₓ control suppresses the benefits of the inherent low NOₓ operation of Miller cycle applications. At an equivalent turbocharger efficiency representative of high boost operation, Miller cycle reduced NOₓ emissions by 31% and elevated exhaust temperatures relative to the conventional IVC case without compromising fuel consumption. The TBC piston's insulative properties shifted the inflection point of the heat transfer and exhaust loss tradeoff such that the optimum IVC timing is more extreme than with the uncoated piston for the fixed NOₓ emissions and turbocharger efficiency cases.PHDMechanical EngineeringUniversity of Michigan, Horace H.

Chemical characterization of pitch deposits produced in the manufacturing of high-quality paper pulps from hemp fibers

Instituto de Recursos Naturales y Agrobiología, CSIC, P.O. Box 1052, E-41080, Seville, Spain E-mail address: [email protected] composition of pitch deposits occurring in pulp sheets and mill circuits during soda/anthraquinone pulping and elemental chlorine-free pulp bleaching of bast fibers of industrial hemp (Cannabis sativa) has been studied. Pitch deposits were extracted with acetone, and the extracts analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Acetone extracts (15-25% of pitch deposits) were constituted by the defoamers used at the mill and by lipophilic extractives from hemp fibers. Acetone-insoluble residues (75-85% of pitch deposits) were analyzed by pyrolysis-GC/MS in the presence and absence of tetramethylammonium hydroxide. These residues were constituted by salts of fatty acids (arising from hemp fibers) with calcium, magnesium, aluminum and other cations that were identified in the deposits. It was concluded that inappropriate use of defoamer together with the presence of multivalent ions seemed to be among the causes of hemp extractives deposition in the pitch problems reported here.This study has been supported by the Spanish Ministerio de Ciencia y Tecnología (MCYT) and FEDER funds (projects 2FD97-0896-C02-02 and AGL2002-00393).

Non-archimedean stratifications in T-convex fields.

We prove that whenever T is a power-bounded o-minimal theory, t-stratifications exist for definable maps and sets in T-convex fields. To this effect, a thorough analysis of definability in T-convex fields is carried out. One of the conditions required for the result above is the Jacobian property, whose proof in this work is a long and technical argument based on an earlier proof of this property for valued fields with analytic structure. An example is given to illustrate that t-stratifications do not exist in general when T is not power-bounded. We also show that if T is power-bounded, the theory of all T-convex fields is b-minimal with centres. We also address several applications of tstratifications. For this we exclusively work with a power-bounded T. The first application establishes that a t-stratification of a definable set X in a T-convex field induces t stratifications on the tangent cones of X. This is a contribution to local geometry and singularity theory. Regarding R as a model of T, the remaining applications are derived by considering the stratifications induced on R by t-stratifications in non-standard models. We prove that each such induced stratification is a C1-Whitney stratification; this in turn leads to a new proof of the existence of Whitney stratifications for definable sets in R. We also deal with interactions between tangent cones of definable sets in R and stratifications

SISTEMA ELECTRÓNICO DE CONTROL EMBEBIDO CON PROTOCOLO DE COMUNICACIÓN I2C PARA EL CONTROL DEL CLIMA DE UN INVERNADERO POR VENTILACIÓN FORZADA POR MEDIO DE UN EXTRACTOR DE VÓRTICE DE ROTACIÓN INVERTIDA (ELECTRONIC CONTROL SYSTEM ENBEBIDO WITH I2C COMMUNICATION PROTOCOL FOR THE CONTROL OF THE CLIMATE OF THE GREENHOUSE STANDARD FOR FORCED VENTILATION THROUGH THE UN INVERTED ROTATION VORTICE EXTRACTOR)

ResumenEste trabajo se centra en el control del clima del invernadero por medio de la ventilación forzada a través de las cenitales y la segunda ley de la termodinámica.El uso de este sistema deja atrás las costosos máquinas de refrigeración del marcado extranjero y es capaz de mantener en horas pico de calor (14:00-15:00 horas) una temperatura por debajo de los 38 °C en una hectárea de invernadero con planta de tomate en suelo. Su funcionamiento se cimienta en la segunda ley de la termodinámica que dice: “la cantidad de entropía de cualquier sistema aislado termodinámicamente tiende incrementarse con el tiempo, hasta alcanzar un valor máximo. Pero sensiblemente, cuando una parte de un sistema cerrado interactúa con otra parte, la energía tiende a dividirse por igual, hasta que el sistema alcance un equilibrio térmico”, por esta razón la ventilación forzada es tan efectiva.  Palabra(s) Clave: Clima, control, invernadero, protocolo I2C, datos.AbstractThis work focuses on controlling the climate of the greenhouse by means of forced ventilation through the zeniths and the second law of thermodynamics.The use of this system leaves behind the expensive cooling machines of the foreign marking and is able to maintain a hot temperature (14: 00-15: 00 hours) at a temperature below 38 °C in a hectare of greenhouse tomato plant in soil. Its operation is based on the second law of thermodynamics that says: "the amount of entropy of any thermodynamically isolated system tends to increase with time, until reaching a maximum value. But sensibly, when one part of a closed system interacts with another part, the energy tends to divide equally, until the system reaches a thermal equilibrium, "for this reason forced ventilation is so effective.Keywords: Climate, control, greenhouse, I2C protocol, data
