Abstract:

This ethnoarchaeological study explores the economics of pottery production and distribution in the Kalinga village of Dalupa in the northern Philippines. For individual Dalupa potters, pottery production is a part-time craft specialization that fits around an intensive cultivation schedule. For the regional economic system in which Dalupa participates, pottery production is a community-based specialization that provides numerous settlements with much-needed goods. This model of community-based specialization, in which households and communities pursue multiple types of productive specialization, is common among traditional societies that anthropologists study. Yet surprisingly little is known about conditions under which village-based specialization develops. Still less is known about the factors that encourage a part-time production system to evolve into a full-time system, since ethnographic examples indicate that productive intensification characterizes a wide range of societies. Historical and social contexts of Dalupa ceramic production are explored as they affect the nature of its production system. Resource access and production parameters that archaeologists employ (e.g., scale, intensity) are influenced by capitalist penetration into the area, social relations, and the level of tribal warfare. Household pottery production scale is affected by the availability of alternative income-generating activities, which fluctuate in response to externally-imposed pressures toward development in the Cordillera highlands. Examination of Dalupa production scale (i.e., levels of inputs and outputs) over an annual cycle reveals that variability within the producer work force is related to differential economic pressures. Analyses of Dalupa production intensity (or the relative level of inputs per production entity) concentrate on dimensional variability of cooking pots. Comparisons at the inter-community and intra-community level evaluate widely-held assumptions regarding the relationship between production intensity and product standardization. This ethnoarchaeological case study provides detailed information on the relationship between production scale and distributional range in small-scale systems. Economic personalism operates in all aspects of the Dalupa pottery exchange network. Dalupa ceramics circulate within a multi-centric economy. These two processes affect the formal variation in the material record of pottery distribution. Investigating both production and distribution processes within a single economic system illuminates our understanding of prehistoric pottery economics.

Abstract:

In the past two decades, ethnoarchaeological methods have grown in importance because of their unique ability to shed direct light on relationships between material culture patterns and social behavior. Ethnoarchaeological research in extant societies allows archaeologists to observe specific examples of how material culture reflects social behavior. The present study demonstrates the value of economic data to ethnoarchaeological analyses. Data collected in 1987-1988 in the Kalinga village of Dangtalan are analyzed from an economic perspective at the household level. Relative household wealth totals are computed for a sample of 56 Dangtalan households. Correlations are explored between wealth and several pottery variables, and between wealth and architectural variables. Results indicate that pottery and architecture in Dangtalan possess certain patterns which correlate in varying degrees with household wealth. Possible implications for archaeology, and potential problems of application are explored.

Abstract:

This ethnoarchaeological study addresses refuse disposal and site formation processes in a village setting, focusing on one artifact class (ceramics) and one type of refuse accumulation (middens). Archaeologists have long relied on middens for large artifact samples. Midden ceramics in particular can contribute to studies of household and community composition, activities, status differences, and food-preparation methods, but interpretations often require linking discarded ceramics to their source, if only in a general sense, and assessing the representativeness of the ceramic sample. This case study provides a model for determining midden catchments, illustrates the variables affecting ceramic deposition, and compares midden ceramics to systemic ceramic assemblages. The deposits themselves are also described in detail, linking observed midden formation processes with the resulting physical and chemical properties. Fieldwork was conducted in February-July 2001 in Dalupa, Kalinga Province, the Philippines, as part of the Kalinga Ethnoarchaeological Project. Residents of Dalupa are subsistence rice farmers, and traditional ceramic production continues despite the availability of metal and plastic alternatives. The 71 households in the community participated in household vessel inventories and weekly interviews to track ceramic vessel breakage and general discard patterns. Thirty active middens were identified in Dalupa, occupying roughly nine percent of the residential area. Twenty-eight of these middens were characterized using some or all of the following methods: surface maps, surface transects for artifact recording and collection, systematic cores for depth, pH measurements, excavated test units, and chemical analysis of soil samples. Observations of midden activity and soil profiles in and around Dalupa provide information on cultural and natural disturbance processes. The result is a picture of midden formation and the creation of midden ceramic assemblages in one community.

Abstract:

This is a story of a social movement's conception and the articulation of its meaning and meaningfulness. Gawad Kalinga, an ambitious Philippine community development cum nation building movement, initiated "GK777" to build 700,000 homes in 7,000 communities, in seven years. I assessed the national and global implications of this social movement's social networking model of nation-building through community development, poverty alleviation, and slum eradication. Using an ethnographic case study to conduct an inductive, grounded theory analysis, the study sought to explore if strategies and actions that go beyond traditional and conflict-centered social movement conceptions are enabling it to achieve their goals and to transfer its model to five other countries. The global implications and replicability of GK's nation-building model on the emergence and development of other forms of social movements, civil society-state governance, are compelling. The attempt at articulating and integrating political process and opportunity structure, resource/ structure mobilization, framing process, and new social movement theories in explaining another form of social movement and of civil society highlights the suitability for such kind of research, long-term monitoring and evaluation, and theorizing.

Abstract:

The narrative paths of Edward Dozier's works "Mountain Arbiters" and "The Kalinga of Northern Luzon, Philippines" are examined and discussed. Dozier's field notes (on file at the Arizona State Museum Archives), recent interviews with both Fred Eggan and William Longacre, as well as Dozier's biographical data and professional orientations are utilized to assess his narrative work in a postmodern framework. Dozier's narrative structure is found to be constrained to neither of Bruner's (1986) categories of dominant emplotments; instead, Dozier's work is described as transitional between the 1930s narratives of acculturation and the 1970s narratives of resistance.

Full text

Abstract:

The earliest indirect evidence of basketry through clay impressions extends back to about 11,000 years (in the Jomon Period), in Egyptian tombs, in early Peruvian sites or the cliff dwellers of the American Southwest. An artifact that has had a long tradition--yet their exact appearance in the archaeological record may never be known with certainty because of factors of preservation. The production of basketry is one of the oldest non-lithic crafts in the world and the evidence of this industry has been continued with little change down to the present time and is very sensitive indicators of cultural chronology. Basketry in contrast to pottery provides a finite number of logical alternatives and the possible combinations are culturally determined to a very high degree. The weaver's relationship with any type of basket is predicated on and conditioned by the fact that all of the weaver's manufacturing choices are physically represented in the finished specimen. It is unfortunate that basketry has not been a major focus of material culture research by archaeologists primarily because of the loss of preservation of baskets in archaeological context. The extant inventory of prehistoric basketry from different parts of the world is but a dim reflection of the original incidence of manufacture. It is unfortunate that basketry has not been a major focus of material culture research by archaeologists and is misunderstood as an artifact class. This ethnoarchaeological study has been initiated to explore the production technology between basket weaving specialists and non-specialists and the distribution of the craft among the Kalinga in the Cordilleras of northern Philippines. The analysis of Kalinga basketry technology and evaluating the economics of the craft is discussed. It hopes to provide a parallel and contrasting understanding of basketry production alongside pottery production extensively researched by the Kalinga Ethnoarchaeology Project. Investigating the initial processes of basketry production, distribution and consumption among the Kalinga should illuminate the understanding of the prehistory of basketry. In the assumption, that the Kalinga is roughly analogous as a neolithic society, popularized in the turn of the century for their headhunting pursuits and a codified custom law.

Abstract:

La place et le rôle de la femme dans les sociétés caribéennes ont fait l’objet de nombreuses études notamment avec la notion de « poto-mitan ». Cependant, compte tenu de la présence des peuples amérindiens au sein des territoires caribéens, une étude de la condition féminine chez les kalinago et les garifuna était à envisager. Il s’agit de se focaliser sur la femme amérindienne par le biais d’une étude socio-culturelle contemporaine. Des concepts tels que l’hybridité, l’identité, le pouvoir, ou encore la créolisation sont des éléments essentiels au développement de l’argumentaire scientifique. Des auteurs relevant de la théorie postcoloniale, du féminisme mais également de la psychanalyse sociale tels que Bhabha, Glissant, Foucault, ou Barriteau seront pris en compte tout au long de la thèse. Ainsi, en adoptant le postulat selon lequel la mondialisation et la régionalisation de l’espace caribéen ont eu une influence sur les figures féminines kalinago et garifuna, il convient de vérifier par le biais d’une méthode de recherche sociologique comparative à la fois dans le temps et dans l’espace, quelles ont été les modalités de mise en œuvre de la définition d’une subversion de la femme amérindienne caribéenne face à son endogroupe. L’objectif général de la thèse est de montrer que le processus de transculturation qu’est l’amérindianité caribéenne, amorce une démarche émancipatrice de la condition des femmes kalinago et garifuna, à travers les concepts de citoyenneté culturelle et d’empowerment
The place and role of women in Caribbean societies have been the subject of numerous studies, in particular with the notion of "potomitan". However, in view of the presence of Amerindian peoples within the Caribbean territories, a study of the status of women in Kalinago and Garifuna was to be considered. It is a matter of focusing on Native American women through a contemporary socio-cultural study. Concepts such as hybridity, identity, power, or creolization are essential elements in the development of scientific arguments. Authors of postcolonial theory, feminism but also social psychoanalysis such as Bhabha, Glissant, Foucault, or Barriteau will be taken into account throughout the thesis. Thus, by adopting the premise that globalization and the regionalization of the Caribbean space have had an influence on the female figures of kalinago and garifuna, it is necessary to verify by means of a comparative sociological method of research both in the time and space, what were the modalities of implementation of the definition of a subversion of the Amerindian woman Caribbean in her social group.The general objective of the thesis is to show that the process of transculturation, Caribbean Amerindianity, initiates an emancipatory approach to the condition of Kalinago and Garifuna women, through the concepts of cultural citizenship and empowerment

Abstract:

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2011.
Cataloged from PDF version of thesis.
Includes bibliographical references (p. 47-48).
This thesis analyzes the thermodynamics of a power system coupling two renewable heat sources: low-temperature geothermal and a high-temperature solar. The process, referred to as a dual-temperature geothermal-solar Kalina hybrid cycle, is analyzed in detail and then compared to appropriate single-heat source power systems, in order to assess any thermodynamic synergies. With increasing demand for more efficient renewable sources of power generation, a plant design where the working fluid is heated (and partially vaporized) by low- to medium-temperature geothermal brine, before being further vaporized by solar heat, presents an opportunity for efficient operation of the power plant. Given a set of design parameters and the constrained optimization of decision variables, a design basis plant configuration is first chosen. Then, the power output attained by the Kalina hybrid is compared to that attained by a combination of a geothermal organic Rankine cycle and a solar standalone steam cycle, with the same boundary conditions. The Kalina hybrid plant is found to produce 9.5 MW of power, with 100 kg/s of geothermal brine and a solar-to-geothermal heat input ratio constrained to 1. The system performance is increasing in the working fluid low pressure and decreasing in the ammonia molar concentration, at the cost of a corresponding increase in solar-to-geothermal heat input ratio. On a design power comparison basis, the hybrid configuration displays no thermodynamic synergy between geothermal and solar energy modes. Specifically, the hybrid plant produces 29% less net power than the combined single-energy mode plants. No assessment of possible economic synergies is attempted. Potential changes to the current Kalina hybrid cycle that can lead to higher thermodynamic performance include regenerating heat within the cycle; using the solar high quality heat source in alternative locations in the cycle; employing one pressure-turbine loop instead of two; using reheat between the two turbines; and investigating other plausible working fluid mixtures including hydrocarbons and refrigerants.

Basé sur une recherche ethnographique de neuf mois, ce mémoire présente une étude comparative des incertitudes, risques et vulnérabilités vécues à l’ère d’instabilités environnementales et climatiques aux Philippines, ainsi qu’aux enjeux contemporains liés à la sécurité ainsi qu’à la gouvernance de l’eau dans les hautes terres de Kalinga, une province située dans la région administrative de la Cordillère au nord de l’île de Luçon. Divulguant, pour ce faire, les fondements et les opérations du gouvernement coutumier de l’eau d’irrigation, cette étude souligne les fondements intrinsèquement politiques de la disponibilité et de l’accessibilité de l’eau comme ressource, ainsi que pour la protection des droits autochtones et le développement des ressources naturelles.

Based on a nine-month ethnographic research conducted in 2015 and 2016 amongst three indigenous communities of the Kalinga highlands, a province and ancestral domain located in the Cordillera Administrative Region of Northern Luzon (Philippines), this comparative academic study examines the local experiences and responses to contemporary threats to safe and sufficient supplies of irrigation water. It further provides a detailed account of the constitution and functions of prevailing customary water governance systems and practices. This study, thus, defends the need to correlate water security to governance, whilst insisting upon the importance of articulating preventive and responsive policies and interventions with local contexts and conditions.

Abstract:

The primary objective of this work is to determine the Kalina cycle's suitability for thermal power conversion from a pressurized water reactor. Several previous papers have examined this application, but these either lack proof of concept or make unfeasible assumptions. This work expands current knowledge by simulating the Kalina cycle and comparing it to current pressurized water reactor Rankine cycles in order to identify which is more efficient. Prerequisite to the modeling is a simulation tool capable of modeling the thermodynamics of ammonia/water mixtures. Instead of using an existing program, a new one called Clearwater is used. This tool is based on a preexisting Gibbs free energy "super" equation of state. Algorithms for vapor-liquid equilibrium calculations and phase identification are presented. Clearwater will be distributed online as open-source code to aid future developers of ammonia/water power and refrigeration cycles. A comparison of single-stage Kalina and Rankine cycles driven by heat from PWR core coolant suggests that the Kalina cycle is not well suited to the application. Any benefit from the Kalina cycle's ability to match temperature profiles in the boiling region of the steam generator is outweighed by other drawbacks. These include the cycle's 1) increased turbine exhaust pressure and 2) lower average heat absorption temperature caused by its working fluid's relatively high liquid heat capacity, both of which lower efficiency. Having concluded this, an attempt is made to quantify the conditions under which the Kalina cycle produces more power than the Rankine cycle. Both cycles are optimized for a range of heat source inlet and outlet temperatures between 350 â„ƒ and 525 â„ƒ. When both cycles absorb the same amount of heat from the source"”i.e., when source outlet temperature is constrained"” the Kalina cycle is less effective for small source temperature drops. When outlet temperature is unconstrained, the Kalina cycle outperforms the Rankine cycle for all but the lowest inlet temperature. This is due to the Kalina cycle's non-isothermal boiling profile, which allows it to absorb low temperature heat at relatively high pressure. Because of its isothermal boiling profile, the Rankine cycle cannot capture low temperature heat as effectively, so it performs worse over large, unconstrained source temperature drops.

Abstract:

Ingeniero Civil Mecánico
Chile tiene uno de los recursos solares de mayor calidad en el mundo, el cual no está siendo aprovechado mayormente. Una forma en que se puede utilizar este recurso es captándolo como energía solar térmica. El ciclo Kalina, inventado a principios de la década de 1980, es un ciclo de potencia cuya principal característica es el fluido de trabajo que utiliza, que es una mezcla binaria, típicamente amoníaco agua. En este trabajo se encuentran rangos favorables de condiciones de operación del ciclo Kalina, para generación eléctrica de 0,5 a 4 [MW], a partir de energía solar térmica de baja temperatura (80 200 [°C]). Se desarrollan y validan modelos termodinámicos por la primera y segunda leyes de la termodinámica de los ciclos Kalina y Rankine Orgánico, este último con los fluidos de trabajo R123, R134a y R152a. Los modelos son validados reproduciendo resultados de la literatura encontrándose una buena concordancia. Se realiza un análisis paramétrico a los ciclos Kalina y Rankine Orgánico, investigando la sensibilidad de los rendimientos térmico y exergético al variar la presión en el evaporador solar, la concentración de amoníaco, la temperatura de la fuente de calor, el pinchpoint y la potencia neta. Se encuentra en el ciclo Kalina que se debe evitar un título de vapor excesivamente bajo a la salida del evaporador solar, porque esto tiene un efecto negativo sobre los rendimientos térmico y exergético. Los componentes con la mayor destrucción de exergía son el condensador, la turbina, el evaporador solar y el regenerador. Al variar la potencia neta las variables extensivas crecen linealmente con ésta. Por último, se encuentran las condiciones de operación más favorables del ciclo Kalina en función de la temperatura de la fuente de calor, para alcanzar el máximo rendimiento exergético. En el ciclo Rankine Orgánico se encuentra que el máximo rendimiento exergético se alcanza a la máxima presión admisible en el evaporador solar, y con R152a como fluido de trabajo. Al comparar los ciclos Kalina y Rankine Orgánico se encuentra que el primero alcanza un mayor rendimiento térmico y exergético que el segundo, sin embargo, requiere de una presión en el evaporador solar de un 40% mayor. A bajas presiones en el evaporador solar la diferencia entre ambos ciclos, a favor del ciclo Kalina, es significativamente mayor que a altas presiones. El mayor rendimiento del ciclo Kalina significa que requiere de una menor área de colectores solares, lo cual generalmente resulta crítico en aplicaciones de energía solar.

Abstract:

Archaeologists rely heavily on pottery data to make inferences about the past. Although a critical component of such inferences is knowing how the pots were used, archaeologists at present cannot reconstruct accurately pottery function. This research provides the means whereby actual pottery use can be determined from traces that remain on pots. The study focuses on an analysis of nearly 200 vessels collected in the Kalinga village of Guina-ang. Traces, in the form of organic residues, attrition, and carbon deposits, are linked to pottery use activities observed in Kalinga households. The analysis of organic residue focuses on fatty acids absorbed into the vessel wall; samples are taken from Kalinga cooking pots and several types of food. It is found that rice cooking pots can be discriminated from vegetable/meat cooking pots, though individual plant species cannot be distinguished in the latter. In several cases, however, there is conclusive evidence for meat cooking. An analysis of Kalinga "archaeological" sherds was also performed to look at fatty acid preservation. A pottery attrition analysis, similar to the study of lithic use-wear, is also performed on Kalinga pottery. The objective is to understand the general principles in the formation of an attritional trace. Nine areas on Kalinga cooking vessels are found to have attritional patches. The two forms of Kalinga cooking vessels could be discriminated based on attrition. Carbon deposits reflect what was cooked, how it was heated, and some general activities of cooking. Interior carbon deposits result from the charring of food and is governed by the source of heat, intensity of heat, and the presence of moisture. The processes that govern the different types of exterior soot are difficult to identify and several experiments are performed. It is found that soot deposition is controlled by wood type, temperature of the ceramic surface, and the presence of moisture. This research demonstrates that archaeologists can begin looking at organic residues, attrition and carbon deposits to infer how their vessels were used in the past.

Nowadays, the urban chaos brings some problems to the citizens such as mental fatigue, irritability and lack of attention, emphasizing the need for open urban spaces, capable to contribute to the restoration of physical and mental balance of people. By the variety of alternative uses available, many of them related to the stimulus of entertainment activities, the squares have been identified as restorative environments, especially by its potential as a place of leisure. In this context, the objective of this dissertation is to understand the use of the square as leisure environment, by a square in Natal RN, establishing the relationship between environmental and behavioral characteristics. More specifically, I attempt to identify the major activities that happen there, the people that develop them and the spatial and temporal configurations of this occupation. Among the 290 squares available in the city, the Kalina Maia Square was selected, which is located in the district of Lagoa Nova. The case study chosen was based on criteria relating to scale, shape, location on the urban environment, variability of uses and conservation status. In the study were used behavioral mapping place-centered and people-centered, behavior trace analysis and 14 interviews. The results show that the square is used by people from different ages and social classes, subdivided into groups with specific days and times. These users are usually engaged in activities related to various types of leisure, with sports predominance. The relationship between spatial configuration and behavior shows that there is a sectorization of uses, being possible to identify the environmental characteristics that most favor observed activities, especially in relation to shading and presence of furniture and equipment. Moreover, throughout the day it appears that the affordances inherent to the various fixed objects on the square are decoded differently by various categories of users, by giving them insights that help the development of leisure activities that characterize each group

Nesse contexto, o objetivo geral desta disserta??o ? a compreens?o do uso da pra?a como ambiente de lazer, tomando como refer?ncia o estudo de uma pra?a de Natal RN, estabelecendo a rela??o entre suas caracter?sticas ambientais e comportamentais. Mais especificamente, busco identificar as principais atividades que ali acontecem, as pessoas que as desempenham e as configura??es espaciais e temporais dessa ocupa??o. Dentre 290 pra?as existentes na cidade, foi selecionada a Pra?a Kalina Maia, localizada no bairro de Lagoa Nova. A escolha do estudo de caso recorreu a crit?rios relativos ? escala, forma, localiza??o na malha urbana, variabilidade de usos e estado de conserva??o. No estudo utilizei mapeamento comportamental centrado no lugar e centrado nas pessoas, an?lise de vest?gios de comportamento e 14 entrevistas. Os resultados revelam que a pra?a ? utilizada por pessoas de varias idades e classes sociais, subdivididas em grupos com dias e hor?rios espec?ficos. Estes usu?rios geralmente se envolvem em atividades ligadas a v?rios tipos de lazer, com predomin?ncia do esportivo. A rela??o entre configura??o espacial e comportamento mostra haver uma setoriza??o dos usos, sendo poss?vel identificar as caracter?sticas ambientais que mais favorecem algumas das atividades observadas, sobretudo relacionadas ao sombreamento e ? presen?a de mobili?rio e equipamentos. Al?m disso, ao longo do dia verifica-se que as affordances inerentes aos diversos objetos fixos presentes no local s?o decodificadas diferentemente pelas v?rias categorias de usu?rios, proporcionando a eles entendimentos que favorecem o desenvolvimento das atividades de lazer que caracterizam cada grupo

Abstract:

Nowadays more emphasis is made on providing learning possibilities. Every person is an equal member of society irrespective of where he/she lives or what he/she is doing. At present the re-socialisation and probation work done by the penitentiary institutions is exceptionally important. The study of this comparatively new sphere confirms that the issue of teaching/learning of women serving sentence has been hardly analysed. The study is urgent in the sense that the people have to be stimulated to seek knowledge, conditions for learning have to be created and supported irrespective where such people live at given time. It is necessary to induce women serving sentence to make best use of the learning possibilities so that they could successfully use such knowledge when they are released. The reason I chose this theme was that it had not been considered especially as far as women in penitentiary institutions were concerned. It was interesting for me to study the need of the sentenced women for learning and take a closer look at the possibilities provided at the penitentiary institution.

Abstract:

The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. These cycles have the potentialof improved performance regarding electrical efficiency,specific power output, specific investment cost and cost ofelectricity compared with the conventional technology, sincethe mixture working fluids enable efficient energyrecovery.

This thesis shows that the ammonia-water cycle has a betterthermodynamic performance than the steam Rankine cycle as abottoming process for natural gas-fired gas and gas-dieselengines, since the majority of the ammonia-water cycleconfigurations investigated generated more power than steamcycles. The best ammonia-water cycle produced approximately40-50 % more power than a single-pressure steam cycle and 20-24% more power than a dual-pressure steam cycle. The investmentcost for an ammonia-water bottoming cycle is probably higherthan for a steam cycle; however, the specific investment costmay be lower due to the higher power output.

A comparison between combined cycles with ammonia-waterbottoming processes and evaporative gas turbine cycles showedthat the ammonia-water cycle could recover the exhaust gasenergy of a high pressure ratio gas turbine more efficientlythan a part-flow evaporative gas turbine cycle. For a mediumpressure ratio gas turbine, the situation was the opposite,except when a complex ammonia-water cycle configuration withreheat was used. An exergy analysis showed that evaporativecycles with part-flow humidification could recover energy asefficiently as, or more efficiently than, full-flow cycles. Aneconomic analysis confirmed that the specific investment costfor part-flow cycles was lower than for full-flow cycles, sincepart-flow humidification reduces the heat exchanger area andhumidification tower volume. In addition, the part-flow cycleshad lower or similar costs of electricity compared with thefull-flow cycles. Compared with combined cycles, the part-flowevaporative cycles had significantly lower total and specificinvestment costs and lower or almost equal costs ofelectricity; thus, part-flow evaporative cycles could competewith the combined cycle for mid-size power generation.

Abstract:

An investigation into the performance of several combined gas-steam power generating plants’ cycles was undertaken at the School of Engineering and Technology at the University of Hertfordshire and it is predominantly analytical in nature. The investigation covered in principle the aspect of the fundamentals and the performance parameters of the following cycles: gas turbine, steam turbine, ammonia-water, partial oxidation and the absorption chiller. Complete thermal analysis of the individual cycles was undertaken initially. Subsequently, these were linked to generate a comprehensive computer model which was employed to predict the performance and characteristics of the optimized combination. The developed model was run using various input parameters to test the performance of the cycle’s combination with respect to the combined cycle’s efficiency, power output, specific fuel consumption and the temperature of the stack gases. In addition, the impact of the optimized cycles on the generation of CO2 and NOX was also investigated. This research goes over the thermal power stations of which most of the world electrical energy is currently generated by. Through which, to meet the increase in the electricity consumption and the environmental pollution associated with its production as well as the limitation of the natural hydrocarbon resources necessitated. By making use of the progressive increase of high temperature gases in recent decades, the advent of high temperature material and the use of large compression ratios and generating electricity from high temperature of gas turbine discharge, which is otherwise lost to the environment, a better electrical power is generated by such plant, which depends on a variety of influencing factors. This thesis deals with an investigation undertaken to optimize the performance of the combined Brayton-Rankine power cycles' performance. This work includes a comprehensive review of the previous work reported in the literature on the combined cycles is presented. An evaluation of the performance of combined cycle power plant and its enhancements is detailed to provide: A full understanding of the operational behaviour of the combined power plants, and demonstration of the relevance between power generations and environmental impact. A basic analytical model was constructed for the combined gas (Brayton) and the steam (Rankine) and used in a parametric study to reveal the optimization parameters, and its results were discussed. The role of the parameters of each cycle on the overall performance of the combined power cycle is revealed by assessing the effect of the operating parameters in each individual cycle on the performance of the CCPP. P impacts on the environment were assessed through changes in the fuel consumption and the temperature of stack gases. A comprehensive and detailed analytical model was created for the operation of hypothetical combined cycle power and power plant. Details of the operation of each component in the cycle was modelled and integrated in the overall all combined cycle/plant operation. The cycle/plant simulation and matching as well as the modelling results and their analysis were presented. Two advanced configurations of gas turbine cycle for the combined cycle power plants are selected, investigated, modelled and optimized as a part of combined cycle power plant. Both configurations work on fuel rich combustion, therefore, the combustor model for rich fuel atmosphere was established. Additionally, models were created for the other components of the turbine which work on the same gases. Another model was created for the components of two configurations of ammonia water mixture (kalina) cycle. As integrated to the combined cycle power plant, the optimization strategy considered for these configurations is for them to be powered by the exhaust gases from either the gas turbine or the gases leaving the Rankine boiler (HRSG). This included ChGT regarding its performance and its environmental characteristics. The previously considered combined configuration is integrated by as single and double effect configurations of an ammonia water absorption cooling system (AWACS) for compressor inlet air cooling. Both were investigated and designed for optimizing the triple combination power cycle described above. During this research, tens of functions were constructed using VBA to look up tables linked to either estimating fluids' thermodynamic properties, or to determine a number of parameters regarding the performance of several components. New and very interesting results were obtained, which show the impact of the input parameters of the individual cycles on the performance parameters of a certain combined plant’s cycle. The optimized parameters are of a great practical influence on the application and running condition of the real combined plants. Such influence manifested itself in higher rate of heat recovery, higher combined plant thermal efficiency from those of the individual plants, less harmful emission, better fuel economy and higher power output. Lastly, it could be claimed that various concluding remarks drawn from the current study could help to improve the understanding of the behaviour of the combined cycle and help power plant designers to reduce the time, effort and cost of prototyping.

The aim of this paper is to explore the introduction and influence of electricity in a Kalinga village, Northern Luzon, the Philippines. In 2010, electricity was gradually introduced to this village and therefore transformed the relations within and without the village. This thesis focuses on the transformation brought about by electricity as well as the confluence of political and economical forces revealed thereof. Despite under different political sovereignty, Cordillera Central Mountains, where this Kalinga village located, had been considered as a marginal and secluded area occupied by rebels. As a matter of fact, however, the interaction with and struggle against power networks between the state and the capitalists never ceased. As a result of the complicated networks produced by the introduction of electricity—including demand of electrical energy, political bargaining, ecological equilibrium, local security and profit grafting—the core of this paper is electricity. The introduction of electricity was politically significant; it was a new phase of local governing. Electricity not only transformed the relationships within the village, but also reorganized the distance and interaction between the village and the outside world. In addition, electricity even re-mapped the boundary of inside/outside. While the state and the capitalists used electricity as a governing mechanism, the villagers figured out counter-strategy through their marginal positions. By means of agriculture and local business, the villagers constructed an ecological network to maintain local security. Consequently, the marginality of this Kalinga village contains multiple components and possibilities.

Dissertação de Mestrado em Energia para a Sustentabilidade apresentada à Faculdade de Ciências e Tecnologia
Ao olhar atentamente para o panorama global das sociedades contemporâneas, pode-se afirmar que, com a viragem do século, uma nova consciência mundial para a problemática ambiental e energética está presente nas nossas vidas, com um impacto profundo no desenvolvimento sustentável das sociedades. Neste âmbito, este trabalho teve como objetivo analisar o processo de fabrico de uma cimenteira em Portugal, de forma a identificar um sistema de recuperação de energia dos excedentes gasosos, avaliando os benefícios, mas também, as barreiras à sua implementação. Ao nível da gestão da energia elétrica da cimenteira foram analisados os consumos de energia inerentes ao processo de fabrico, com o intuito de identificar as componentes plausíveis de serem satisfeitas com um sistema de produção de energia elétrica a partir do calor dos gases residuais. As correntes de gases analisadas correspondem aos gases excedentes do topo da torre de pré-aquecimento, provenientes do forno, os gases excedentes do arrefecedor de clínquer e os gases excedentes da picagem do bypass. Os cálculos foram efetuados de forma a não comprometer os restantes equipamentos que se encontram no circuito de gases excedentes. Em complemento, e como forma de avaliar o interesse económico das soluções tecnológicas, foi também efetuada uma análise à gestão dos consumos de energia elétrica em função do tarifário contratualizado, de forma a reduzir os custos de energia elétrica através de uma gestão mais eficiente de utilização dos equipamentos. Das várias possibilidades estudadas, a utilização de um sistema de Ciclo de Rankine Orgânico para aproveitar os gases de todas as fontes foi a solução que apresentou maior interesse, originando um potencial energético de 2,31 MW. Para esta situação é expectável um investimento de cerca de 7 milhões de Euros e, considerando 7,2% de energia para autoconsumo da central turbo-geradora, estimou-se um período de retorno de cerca de 10 anos.
By looking closely at the global picture of contemporary societies, one can say that at the turn of the century, a new global awareness of environmental and energy issues is present in our lives, with a profound impact on the sustainable development of societies. In this context, the objective of this work was to analyse the manufacturing process of a cement plant in Portugal, in order to identify a system to recover energy from the gaseous surplus, evaluating the benefits, but also the barriers to its implementation.At the level of the electrical energy management of the cement plant, the typical energy consumptions of the manufacturing process were analysed, in order to identify the plausible components to be satisfied with a systems of electric energy production through the heat of the waste gases. The analysed gas streams correspond to the excess gases from the top of the preheating tower coming from the kiln, the surplus gases from the clinker cooler and the excess gas from the bypass chopping. Calculations were made in a way that did not compromise the remaining equipment in the excess gas circuit. In addition, and as a way of evaluating the economic interest of technological solutions, it was also possible to carry out an analysis of the management of the consumption of electric energy in function of the contracted tariffs, in order to reduce electric costs through a more efficient management equipment.Of the various possibilities studied, the use of an Organic Rankine Cycle system to take advantage of the gases from all sources was the solution that presented the greatest interest, resulting in an energy potential of 2,31 MW. For this situation, an investment of around 7 million Euros is expected, and considering a 7,2% of energy for self-consumption of the turbine-generator, a return period of around 10 years was estimated.

O presente trabalho estuda a possibilidade de se adaptar o ciclo termodinâmico de Kalina a sistemas de micro co-geração, utilizando fontes térmicas de baixa temperatura. Os ciclos estudados têm configurações tecnológicas iguais às do ciclo termodinâmico de Rankine, tendo sido considerado um ciclo com regenerador e outro sem regenerador. Foi também estudado o comportamento do ciclo de Rankine, nas mesmas condições, para fins comparativos com o ciclo de Kalina. Os fluidos usados nos ciclos foram água e R123 para os casos de Rankine, e uma mistura amónia-água para o caso de Kalina sendo que neste foram tidas em conta diferentes concentrações de amónia na mistura. Os ciclos referidos foram analisadas usando uma fonte quente à temperatura de 150 ºC e outra à temperatura 200 ºC, ambas modelam gases de escape de uma caldeira. Qualquer uma das aplicações rejeita calor para uma fonte fria modelada como água a 10 ºC. A metodologia de cálculo está dividida em dois passos principais: o primeiro analisa o comportamento do ciclo em termos de rendimento térmico e de potência produzida na turbina, o segundo estuda o modo como os diferentes ciclos aproveitam a energia das fontes quentes e da fonte fria. As principais conclusões mostram que os ciclos de Kalina podem produzir mais potência que os ciclos de Rankine, pelo facto de aproveitarem melhor as características da fonte quente, arrefecendo-a até temperaturas mais baixas. Mostra-se que o ciclo de Kalina é também o melhor no que respeita ao aquecimento da fonte fria e apresenta, na maioria dos casos, um rendimento térmico melhor. Faz ainda parte deste trabalho um estudo de primeira aproximação ao modo como se devem estudar as propriedades termodinâmicas de uma mistura, desde o modo como se manipulam as equações de estado, passando pelo cálculo de temperaturas de início e fim de mudança de fase (temperaturas de bolha e orvalho), até à definição de propriedades termodinâmicas como entalpia e entropia.
Abstract This work studies the possibility to adapt the Kalina thermodynamic cycle to a MCHP system by using a heat source at low temperature. The technological configuration of the cycles is equal to that of the Rankine thermodynamic cycle, one with regenerator and another without regenerator. The Rankine cycle was also studied in order to compare his behaviour with the Kalina cycle in the same conditions. The working fluids that were used were water and R123 for Rankine applications and an ammonia-water mixture for Kalina’s, in which different percentages of ammonia in the mixture were studied. The cycles were applied to two different heat sources, one at 150 ºC and another at 200 ºC, either one is representative of exhaust gases from a boiler. The sink, to where the cycles reject heat, was modelled as water at 10 ºC. The methodology of analysis was divided in two principal steps: the first concerns about the behaviour of the cycles in terms of thermal efficiency and power generated in the turbine and the second one analyses how the cycles manage to use the sources of heat and the sink. The main conclusions show that the Kalina cycle can generate more power due to the fact that it can cool down the temperature of the heat source more than the Rankine cycle. It’s also shown that the Kalina cycle performed better in what concern to warm up the sink as well as for the majority of the tests that took care about the thermal efficiency. In this work, a study on how a mixture of components should be studied, also took place. The way to adapt Equations of State, how to calculate bubble and dew temperatures and how to calculate thermodynamic properties like enthalpy or entropy is also shown.

Abstract:

This study examined how remittances from Filipinos living in New Zealand and their Associations and Organizations contributed to community development in the Philippines. It specifically examined the impacts of both individual and collective remittances to the household and community level and on the broader society as a whole. This study also identified the opportunities brought about by Filipino remittances from New Zealand to communities of origin in the Philippines and possible avenues for the enhancement of the impact of these remittances at the local community level and on society. Case study as a research methodology was used in the study in order to have an in depth, more exhaustive and more comprehensive understanding of the phenomenon. It helped captured the emerging themes of remittance practices and development work of Filipinos and their Associations and Organizations in New Zealand to communities of origin in the Philippines. It also helped understand the phenomenon in the real life context in which a one shot survey or observation failed to capture. The study found that while it was common for overseas Filipinos to send individual remittances to household members in the Philippines for household use and human investments for family members, this was not always the case for Filipinos in New Zealand. Most Filipino migrants in New Zealand had their immediate family living with them in the host country and they sent individual remittances to the Philippines either as gifts for parents to maintain their livelihood, for investment, and support for the education of nephews and nieces. With collective remittances, individual Filipinos and their Associations and Organizations in New Zealand were actively contributing in the pooling of resources for development works in communities of origins in the Philippines. At the same time, they engaged with their recipient communities in the Philippines in order to establish and maintain their transnational ties for effective implementation of development projects in the home country. The study also found that individual remittances coming from New Zealand for family members in the Philippines had a greater impact on the family as a whole. Remittances helped establish income generating activities in the family that have multiplier effects to the family such as a steady source of income, strong purchasing power and extra money for the health and education of children. Individual remittances coming from New Zealand to support the family activities in the community also helped the name of the family in the Philippines in a good stead. On a community level, collective remittances helped maintain culture and tradition as well as raised funds for the implementation of scholarship programs, medical missions, shelter for orphaned children, and basic infrastructures in the community such as school buildings, community roads and multipurpose halls. Collective remittances also built communities and gave recipients hope for a brighter future through equitable housing scheme, community empowerment, health, and education programs. Filipino Associations and Organizations in New Zealand were good vehicles in finding opportunities in their communities of origin. They must engaged with Filipino Associations and Organizations and local business people in their local communities and built partnership with them on community based development projects for the benefit of the wider community.

Abstract:

Titled as a play on Mindy Kaling’s 2011 book, Is Everyone Hanging Out Without Me? (And Other Concerns), this thesis highlights the obstacles women, the genre of comedy, and dramaturgs face in order to be taken seriously in the arts. Using the work of Mindy Kaling, I explore how she uses comedy as a means of defying the expectations put upon her as an Indian American woman in order to provide context for the ways in which the marginal statuses of women of color and comedy overlap. In an effort to demonstrate the ways in which comedy can be utilized as a tool for social change and the ways in which the work of a dramaturg can support that, this thesis documents the planning and execution of three events that accompany this written document: a production of Mindy Kaling and Brenda Withers’ 2002 play, Matt & Ben; a screening of the 1997 Oscar-winning film, Good Will Hunting; and a Q+A conversation with Broadway’s most-produced female playwright, Theresa Rebeck. My work is shaped by various theoretical frameworks, including intersectional feminism, symbolic annihilation, charged humor, and gender performance theories, seeking to establish that my dramaturgical, comedic, and feminist sensibilities are all driven by the same empathetic impulse that sits at the very core of my artistry and arguing that despite a vast history of marginality, dramaturgs, comics, and women can be powerful agents of change.
