Equilíbrio de fases do monômero L,L-Lactídeo em altas pressões: dados experimentais e modelagem
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Alimentos, Florianópolis, 2014.Abstract : A demanda em larga escala por materiais poliméricos biodegradáveis produzidos a partir de processos limpos, possibilitando a obtenção de produtos livres de resíduos tóxicos, tanto para a aplicação na área farmacêutica quanto alimentícia, possibilitou que processos de polimerização em meio atóxico e mediado por enzimas se tornassem atrativos. Enquanto a maioria dos processos tradicionais de polimerização utiliza como catalisador compostos metálicos tóxicos, que podem deixar traços de resíduos nos produtos, os processos enzimáticos utilizam catalisadores biológicos, considerados ecologicamente corretos. O poli(L-lactídeo), classificado como um polímero biodegradável, biocompatível e bioreabsorvível é empregado com frequência em aplicações nas áreas médica, farmacêutica e alimentícia. Excetuando as pesquisas com dióxido de carbono, o emprego de propano como meio para as reações de polimerização carece de informações, tanto no que tange ao comportamento de fases dos componentes envolvidos nas reações quanto à investigação das variáveis de processos que afetam tais reações. A utilização de gases pressurizados como o propano em substituição ao uso de dióxido de carbono apresenta como principal vantagem a operação em pressões moderadas. Neste sentido, o objetivo geral desse trabalho foi estudar o comportamento de fases a altas pressões do sistema ternário propano + L-lactídeo + etanol nas razões molares de etanol/L-lactídeo de 9:1, 7:1, 5:1 e 3:1, visando à obtenção de dados para a condução do processo de polimerização em fluidos pressurizados. Os experimentos foram realizados usando uma célula de volume variável numa faixa de temperatura de 50 a 80 °C. Nos sistemas investigados foram observadas14transições de fase do tipo líquido-vapor ponto de bolha, sendo que nas razões molares de etanol/L-lactídeo de 7:1 a 3:1 pode-se observar, dependendo da composição do sistema, a reação do L-lactídeo em dímeros e oligômeros de L-lactídeo. Para a razão molar 3:1, na composição investigada, não foi possível visualizar uma região de fase homogênea. Diagramas P-x e P-T foram construídos para os sistemas analisados. Para todas as razões molares de etanol/L-lactídeo investigadas um incremento na temperatura do sistema e/ou um aumento na composição de propano conduziu a pressões de transição mais elevadas. Além disso, para a faixa de composição estudada, pressões moderadas de até 32,0 bar foram encontradas para a completa solubilização do sistema. O sistema ternário investigado neste trabalho e o sistema dióxido de carbono + L-lactídeo + etanol, obtido por Rebelatto (2014), foram modelados utilizando a equação de Peng-Robinson com a regra de mistura de Wong-Sandler, PR(WS). A equação de PR(WS) foi capaz de correlacionar, de forma quantitativa, os diagramas de fases do sistema propano + L-lactídeo + etanol. Já, para a modelagem do sistema ternário dióxido de carbono + L-lactídeo + etanol, a equação de PR(WS) conseguiu descrever o equilíbrio de fases de forma qualitativa. Os dados apresentados neste trabalho fornecem informações importantes para o desenvolvimento, simulação, otimização e condução dos processos de síntese de polímeros em fluidos pressurizados.Abstract : The demand for large-scale biodegradable polymeric materials produced from clean processes, allowing obtaining products free of toxic residues, both for the application in the pharmaceutical field as food, enabled polymerization processes mediated through non-toxic enzymes become attractive. While traditional processes use as polymerization catalyst metal compounds that may leave toxic residues in the product, the enzymatic processes using biological catalysts, which are considerable environmentally friendly. The poly(L-lactide), classified as biodegradable, biocompatible and bioresorbable polymer, is employed frequently in applications in the medical, pharmaceutical and food industries. Except for research on carbon dioxide, the use of propane as a means for polymerization reactions, lacks of information both in terms of the phase behavior of the components involved in the reactions as the investigation of the process variables that affect such reactions. The use of pressurized gases such as propane to replace the use of carbon dioxide presents the main advantage to be operated at moderate pressures. In this sense, the general aim of this thesis was to study the phase behavior at high pressures of the ternary system propane + ethanol + L-lactide, at the molar ratios ethanol/L-lactide of 9:1, 7:1, 5:1 and 3:1 in order to obtain data for the conduct of the polymerization process in pressurized fluids. The experiments were performed using a cell of variable volume over a temperature range from 50 to 80 °C. In the investigated systems the liquid-vapor bubble point phase transition type was observed. Whereas at the ethanol/L-lactide molar rations of 7:1 to 3:1, depending on the composition of the system, the reaction of lactide in dimers and oligomers of L-lactide can be observed. For the 3:1 molar ratio, the composition investigated, it was not possible to view a region of a homogeneous phase. P-x and P-T diagrams were constructed for the16systems analyzed. For all ethanol/L-lactíde molar ratios investigated, an increase in the temperature of the system and/or an increase in the propane composition lead to higher pressures transitions. Additionally, for the whole composition range studied, moderate pressures up to 32.0 bar were found to fully solubilize the system. The ternary system investigated in this work and the system carbon dioxide + L-lactide + ethanol, obtained by Rebelatto (2014), were modeled using the Peng-Robinson with the mixing rule of Wong-Sandler, PR(WS). The PR (WS) equation was able to correlate quantitatively, the phase diagrams of the system propane + ethanol + L-lactide. While that the modeling of the system carbon dioxide + L-lactide + etanol, the PR (WS) equation was able to describe the phase equilibrium in a qualitative manner. The data presented in this study provide important information for development, simulation, optimization and conduction of the synthesis of polymers in pressurized fluids

The impact of author name disambiguation on knowledge discovery from large-scale scholarly data
Get PDFIn this study, I demonstrate that the choice of disambiguation methods for resolving author name ambiguity can adversely affect our understanding of scholarly collaboration patterns and coauthorship network structures extracted from large-scale scholarly data. By utilizing large-scale bibliometric data, scholars in many fields have gleaned knowledge for use in scholarly evaluation, collaborator recommendations, research policy evaluation, and network-evolution modeling. A common challenge has been that author names in bibliometric data are not properly disambiguated: authors may share the same name (i.e., different authors are sometimes misrepresented to be a single author which can lead to a “merging of identities”). In addition, one author may use name variations (i.e., an author may be represented as two or more different authors which can lead to a “splitting of identities”). When faced with these challenges, most scholars have pre-processed bibliometric data using simple heuristics (e.g., if two author names share the same surname and given name initials, they are presumed to represent the same author identity) and assumed that their findings are robust to errors due to author name ambiguity. I test this long-held assumption in bibliometrics by measuring the impact of author name ambiguity on network properties. I accomplish this under varying conditions, including network size and cumulative time window (from 1991 to 2009) using four large-scale bibliometric datasets that cover: biomedicine, computer science, psychology and neuroscience, and one nation’s entire domestic publication output. For this task, I collate the statistical properties of coauthorship networks constructed from algorithmically disambiguated data (i.e., close to clean data) against those that come from the same networks, but are compromised by misidentified authors via first-initial and all-initials disambiguation methods. In addition, I simulate the levels of merging and splitting incrementally using those empirical datasets. My findings show that initial-based name disambiguation methods can severely distort our understanding of given networks and such distortion gets worse over time. Moreover, the distortion sometimes leads to biased or false knowledge of coauthorship network formation and evolution mechanisms such as preferential attachment generating the power-law distribution of vertex degree and to false validation of theories about the choice of collaborators in scientific research. This may result in ill-informed decisions about research policy and resource allocation. Besides measuring the impact of name ambiguity on network properties, I also test how name ambiguity can be estimated using simple heuristics such as dataset size and how merged author identities can be detected via an author’s ego-network properties to provide a practical guidance for corrective measures. My research calls for further studying the effects of author name ambiguity on coauthorship network properties and is expected to help scholars establish better practices for knowledge discovery from large-scale scholarly data.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2019-08-01The student, Jinseok Kim, accepted the attached license on 2017-07-10 at 17:48.The student, Jinseok Kim, submitted this Dissertation for approval on 2017-07-10 at 17:53.This Dissertation was approved for publication on 2017-07-11 at 10:39.DSpace SAF Submission Ingestion Package generated from Vireo submission #11383 on 2017-09-29 at 11:18:25Made available in DSpace on 2017-09-29T16:39:41Z (GMT).

Reason: Author requested U of Illinois access only (OA after 2yrs) in Vireo ETD systemRapid technological advances have accelerated the rate of global consumption and the pace of product disposal. Products are rapidly being disposed of or replaced even though they are functional or have sufficient residual value. A circular system has emerged as an alternative to solve the problems of the existing linear system (take-make-use-dispose). The circular system is a system that keeps resources in use as long as possible and then recovers and regenerates products and materials at the end-of-life stage through end-of-life product recovery strategies such as reuse, recycling, remanufacturing, and refurbishment. Through a circular system, companies can fulfill their social and ethical responsibilities for the environment, respond appropriately to environmental regulations, and obtain economic benefits, but many companies fail to implement the system properly due to a lack of understanding of the market and design strategies for recovery.
Product design determines the product recovery strategy and its effectiveness, as well as the degree of environmental impact that can occur during product development, production, and use. Therefore, it is necessary to design in consideration of the entire product life cycle in the initial design stage. This dissertation focuses on improving product recovery through design decisions, such as product commonality, product module design, and product configuration design. This dissertation presents several methodologies of design for recovery that can help companies achieve a variety of goals, such as profitability and sustainability, as well as efficiency in production processes and protection of sensitive design and information. The methodologies can be used as product design support tools to help product designers identify appropriate product designs and find commonalities within a product family.
The main contribution of this dissertation is the proposal of design methodologies that consider various issues between circular economy and the goals that companies need to achieve, which are rarely considered concurrently in previous studies. The purpose of these methodologies is to identify the obstacles that hinder companies from changing existing linear systems to the circular system and to suggest design strategies to overcome them. Each method provides product design alternatives to minimize design issues that may occur in the application of circular design, such as deterioration of product performance through commonality, intellectual property infringement, the inefficient recovery process, and changes in customer preferences while increasing the possibility of product recovery.
This dissertation consists of three product family design methodologies for closing the loop of product family through remanufacturing, reuse, and recycling (Chapter 3, 4, and 6) and one empirical study on changes in customer preferences caused by COVID-19 (Chapter 5).
The first methodology deals with the impact of intergenerational commonality. This study finds out through a quantitative model how different pricing strategies, production plans, and recovery costs are, based on the designs of a new generation with various degrees of generational commonality. The second methodology aims to identify the sustainable optimal product family architecture design while protecting intellectual property on sensitive parts or modules. The developed approach notably allows the selection of suitable and sustainable commonality candidates. The third methodology presents an integrated model to find product configuration design for remanufacturing and establish a harvest plan that determines the optimal disassembly operations and levels. Smartphones and printer-product families are used as an illustrative case study to explain and validate each methodology.
Lastly, the empirical research includes the study of dynamic changes in customer responses for product features caused by the spread of COVID-19 through sentiment analysis based on online reviews. A case study is conducted using new and refurbished smartphone reviews to investigate the dynamic changes in customer sentiment before/during COVID-19. The importance of the result is shown by comparing it to the actual market data
