Energy and emission impact quantification of pavement preservation using life cycle assessment
No full textThis study aims at developing a life cycle assessment (LCA) model to quantify the impact of pavement preservation on energy consumption and greenhouse gas (GHG) emissions. In the past, most of the research focused on the environmental impact of pavements at material and construction stages but ignored the usage stage. The construction stage analyzed in this study contains energy consumption and GHG emissions at material, manufacture, transportation and placement phases. Vehicle operating cost and fuel economy is affected by change in tire rolling resistance during usage stage. This also affects GHG emissions significantly. In this study the Highway Development and Management (HDM-4) model and the Motor Vehicle Emission Simulator (MOVES) were used to analyze fuel consumption and emissions caused by different vehicles on the pavements treated by different preservation treatments. Surface characteristics such as roughness, texture and deflection were taken into account in tire rolling resistance along with general factors such as speed, traffic volume, and road grade. Two pavement sections with different roughness from the long-term pavement performance (LTPP) database were used in the analysis to illustrate the importance of considering usage stage in LCA. The thin overlay was found to have the highest energy consumption and emissions among four preservation treatments during construction stage, but at the same time resulted in the greatest reduction of energy and emission at usage stage. If only construction stage is considered, energy and emissions are ruled by use of amount of material and manufacture process. The reductions of GHG emission at usage stage are much greater than the GHG emission produced at construction stage for all preservation treatments. Excluding the usage stage will omit the fact that construction stage has less impact on pavement LCA than usage stage. Combining both construction and usage stages gave a life-cycle impact of pavement preservation on energy and GHG emission. The results show that there is a significant amount of change in energy consumption and emissions when traffic factors and pavement surface characteristics are considered during usage stage. The study results provide valuable insights in selecting sustainable pavement maintenance strategies from an environmental view point.M.S.Includes bibliographical referencesby Rashmi Gangara
A new determination of molecular mobility in amorphous materials:
No full textThis research investigated how the steady-state and time-resolved emission and intensity of phosphorescence from vanillin (4-hydroxy-3-methoxy benzaldehyde), a commonly used flavor compound, can be used to probe molecular mobility when dispersed within amorphous pure sucrose films. The luminescence properties and photophysical events of vanillin as a triplet state probe in amorphous sucrose films as a function of temperature was successfully characterized. The peak energy, bandwidth and lifetime data suggest that it is sensitive to molecular mobility and can be used monitor molecular mobility in amorphous sucrose films. Time-resolved phosphorescence intensity decays from vanillin were multiexponential both below and above the glass transition temperature, indicating that the pure (single component) amorphous matrix was dynamically heterogeneous on the molecular level.
Vanillin analogs (hydroxy, dihydroxy and ethyl vanillin)) phosphorescence lifetime were found to be extremely sensitive to the local environment in the amorphous sucrose in the glassy state and at the glass-to-rubber transition into the melt, and provided useful insight about the mechanism of vanillin sensitivity to molecular mobility. Based on this the capability of movement of methoxyl group about the C-O bond is thought to be the contributor to sensitivity of vanillin to matrix molecular mobility. The other possibility is that the effect is not that of larger group but rather that of group (like methoxy and ethoxy) not able to hydrogen bond to matrix, which can have a coupling the probe vibrations to the matrix.
Vanillin phosphorescence demonstrated that the average rate of matrix molecular mobility rates increases with an increase in the molecular size and Tg of the sugar in the glucose homologous series. A comparative study of mobility in three excipients sucrose, trehalose and PVP, using vanillin phosphorescence provided useful insight about their stabilizing effect.
The phosphorescence from probes erythrosin B, vanillin and tryptophan was successfully utilized to measure molecular mobility on three different time scales corresponding to each probe in amorphous sucrose and protein film. Molecular mobility was successfully studied in amorphous sucrose films by monitoring phosphorescence from the dual probe combination of erythrosin B: vanillin, erythrosin B: tryptophan and vanillin:tryptophan.Ph.D.Includes bibliographical referencesby Rashmi Satyanarayan Tiwar

Publisher Copyright: © 2021 The Author(s)Speakers exhibit dialectal traits in speech at sub-segmental, segmental, and supra-segmental levels. Any feature representation for dialect classification should appropriately represent these dialectal traits. Traditional segmental features such as mel-frequency cepstral coefficients (MFCCs) fail to represent sub-segmental and supra-segmental dialectal traits. This study proposes to use frequency domain linear prediction cepstral coefficients (FDLPCCs) for dialect classification inspired by its long temporal summarization during pole estimation. The i-vectors and x-vectors derived from both baseline (MFCCs, linear prediction cepstral coefficients (LPCCs), perceptual LPCCs (PLPCCs), RASTA filtered PLPCCs (PLPCC-R) and proposed (FDLPCC) features are used for identifying the dialects with support vector machine (SVM) and feed-forward neural network (FFNN) as classifiers. Proposed FDLPCC features have shown to perform better than baseline features such as MFCCs and PLPCC-Rs (best among LPCCs variants) by an absolute improvement of 3.4% and 3.9% (in unweighted average recall (UAR)), with i-vector + SVM system and 1.6% and 4.6% (in UAR), i-vector + FFNN system respectively. It is also found that there exists a complementary information between the proposed and baseline features. Furthermore current studies are compared with previous studies and it is found that performances of current studies are better than previous studies.Peer reviewe
A different approach to things: A critical theoretical presentation of non-Western ethnic minority women's opportunity for medical pluralism in Denmark
No full textForfatter: Michelle Toftegaard, stud. cand. san. Institut for Mennesker og Teknologi. Roskilde Universitet.Vejleder: Dr. Rashmi Singla, Institut for Mennesker og Teknologi, Roskilde Universitet.Baggrund: Den øgede internationale udvikling, i anvendelsen af komplementær medicin og dens behandlingsformer, og dens integration med de respektive landes traditionelle medicin, peger i retningen af, at der nu anerkendes et behov for, at udvikle en sammenhængende og integreret tilgang til sundhed. Alene i Danmark fastslår tal, fra 2017, at 1.298.000 af den samlede danske, voksne befolkning har anvendt én eller flere former for alternativ behandling, inden for det seneste år. Med en løbende assimilering, af tidligere betragtede komplementære mediciner - og behandlingsformer, der i dag sikrer et samarbejde mellem det danske sundhedsvæsen og den alternative praksis, er der behov for en definition af denne praksis for, at åbne op for muligheden for medicinsk pluralisme, med respekt for den enkeltes værdiunivers og livsbetingelser.Formål: Nærværende speciale har til formål at undersøge og beskrive, de ikke-vestlige etniske minoritetskvinders erfaringer med -, holdninger til og handlinger i relation til anvendelsen af komplementær medicin og dens behandlingsformer. Med en forankring i den kritiske teoretiske forskningstradition har nærværende speciale desuden til formål at identificere de undertrykkende faktorer, der begrænser de ikke-vestlige etniske minoritetskvinders autonomi, herunder de barrierer, som de oplever for idealet, i fremmelsen af egen sundhed og for at forebygge - og behandle sygdom, i relation til anvendelsen af komplementær medicin og dens behandlingsformer. Nærværende speciales analytiske fund kan således tjene som et bidrag, ved at supplere den eksisterende viden, beroende på kvantitative data, i den vidensbase, som WHO efterspørger.Materialer og metode: Med en mixed methods tilgang, kombinerer nærværende speciale, empirimateriale fra 4 semistrukturerede interviews med ikke-vestlige etniske minoritetskvinder i Danmark, med en dokumentanalyse af WHOs strategidokument WHO Traditional Medicine Strategy 2014-2023. For at opnå den kritiske teoretiske forskningstraditions dobbeltsidet perspektiv, inddrages såvel et oplevelses – og erfaringsperspektiv samt et betragtende perspektiv, som en strategisk tilgang i nærværende speciales analyse. Med en teoretisk referenceramme af Jürgen Habermas komplimenteres nærværende speciales analyse med hans teori om om begrebsparret systemverden/livsverden og dens karakteristika for handlings – og rationalitetstyper.Konklusion: Strategidokumentet, WHO Traditional Medicine Strategy 2014-2023, forsøger at udvide sin formålsrationelle styringskapacitet, på bekostning af livsverdenens kommunikative rationalitet, og efterlader brugerne af komplementær medicin og dens behandlingsformer, i hænderne på markedets logik. Ved at stille brugerne af komplementær medicin og dens behandlingsformer til ansvar for deres egen sundhed, trues den lige adgang til sundhed. Blandt den største barriere for idealet tilhørende de, ikke-vestlige etniske minoritetskvinders oplevelse, i relation til anvendelsen af komplementær medicin og dens behandlingsformer, i fremmelsen af egen sundhed og for at forebygge - og behandle sygdom, er deres møde med det danske sundhedsvæsen og lægerne som repræsentant herfor. Alt imens forsøger de ikke-vestlige etniske minoritetskvinder at beskytte hinanden mod ”upålidelige” og ikke anvendelige behandlingsformer, som en strategi for fremmelsen af egen sundhed.Søgeord: Komplementær medicin og behandling, medicinsk pluralisme, sundhedsfremme, sundhedsfremmestrategi, barriere for humanisering. Author: Michelle Toftegaard, stud. cand. san. Department of People and Technology. Roskilde UniversityGuidance counselor: Dr. Rashmi Singla, Department of People and Technology, Roskilde University.Background: The increased international development in the use of complementary medicine and its therapies, as well as its integration with the respective countries' traditional medicine, point to the need to develop a coherent and integrated approach to health. In Denmark alone, figures from 2017 state that 1,288,000 citizens of the total Danish adult population have used one or more forms of alternative treatment in the past year. With an ongoing assimilation of previously considered complementary medicines and therapies, which today ensure collaboration between the Danish health service and the alternative medical practice, there is a need for a definition of this practice in order to open up the possibility of medical pluralism, with respect for the individual's concept of value and living conditions.Purpose: The purpose of this thesis is to examine what experiences, attitudes and actions non-Western ethnic minority women have in relation to the use of complementary medicine and its therapies. Rooted in the critical theoretical research tradition, this thesis also aims to identify the oppressive factors that limit the autonomy of non-Western ethnic minority women, including those barriers that they experience in regards to the ideal, in nurturing their own health and in preventing and treating illness, in relation to the use of complementary medicine and its therapies. The analytical findings of this thesis can thus serve as a contribution by supplementing the existing knowledge, building upon quantitative data, in the knowledge base requested by the WHO .Materials and method: With a mixed methods approach, this thesis combines empirical data from 4 semi-structured interviews with non-western ethnic minority women in Denmark, with a document analysis of WHO's strategy document ‘WHO Traditional Medicine Strategy 2014-2023’. To achieve the double-sided perspective of critical theoretical research tradition, it involves both an experience perspective as well as a considerate perspective, as a strategic approach in the analysis of this thesis. With a theoretical frame of reference by Jürgen Habermas, the present thesis's analysis is complemented with his theory of about the conceptual system world / life world and its characteristics investigating types of action and rationality.Conclusion: The strategy paper, WHO Traditional Medicine Strategy 2014-2023, seek to expand its objective rational management capacity at the expense of the life world communicative rationality, leaving users of complementary medicine and its treatments in the hands of market forces. By equipping the users of complementary medicine and its therapies with responsibility for their own health threatens equal access to health. Investigating ideals of the non-Western ethnic minority women, they experience one of the greatest barriers in their encounter with the Danish health service and doctors as its representatives - Ideals based on the use of complementary medicine and its therapies, in promoting self-health and in preventing and treating disease. Meanwhile, the non-Western ethnic minority women are trying to protect each other from "unreliable" and inapplicable forms of treatment, as a strategy for nurturing their own health.Searchword: Complementary medicine and treatment, medical pluralism, health promotion, health promotion strategy, barrier to humanization.<br/
An Online Resource Repository for Training Faculty in Laulima: An Organization and Collaboration of Resources
No full textUniversity of Hawaii System adopted an open source course management system (CMS) and converted it to Laulima. The project idea started when campuses within the University of Hawaii System started having individualized resources and services on university CMS tools. A collaboration and organization of the resources and services from these campuses using a centralized online resource repository within the course management system, Laulima was the idea the project proposed.Online Course Management Systems (CMS) have become one of the most popular technologies in teaching and learning today. The University of Hawaii has recently adopted an open source CMS and created a customized version for the University called Laulima. Many campuses in the University of Hawaii System (UH) are duplicating efforts by individually developing resources and employing staff to support faculty use of Laulima. A needs analysis conducted by the author regarding faculty use of Laulima revealed difficulty in accessibility of resources, resource availability, redundancy of resource materials developed by multiple campuses, and the need for self-paced support that can be used after introductory workshops or instead of the lengthy workshops. The purpose of this project was to design, develop and evaluate the usability of an online repository of Laulima tutorials developed at multiple UH campuses and made available to faculty throughout the UH system. Faculty throughout the UH system will have access to the repository through the course management system Laulima and specified staff editors from participating UH campuses will be able to edit and upload the files and tutorials to the online repository. Faculty users, staff editors and Educational Technology graduate students learning how to design an online course using course management systems from the participating campuses evaluated the usability of the centralized online resource repository for a period of ten days. Evaluation data was collected via online surveys and the results indicated the interests of participants and the success of the idea of a centralized online repository. Findings are expected to be of significance to those interested in or developing centralized online collaborative systems
Design of polymeric delivery system with targeted drug release profiles for hydrophilic and lipophilic compounds
No full textThe delivery of hydrophilic drugs and macromolecules through the uppermost layer of the skin, the stratum corneum, is particularly challenging. The use of chemical enhancers, iontophoresis, sonophoresis and microneedles are some methods of overcoming the barrier properties of the skin and achieving transdermal drug delivery. One of the versatile approaches is the use of microneedles for delivery of therapeutic agents to various depths in the skin and in addition for controlled releasing drug polymer coatings. In our study silicon microneedles were coated with a polymer-drug combination. Dip coating and electrospinning, a technique of making polymer nanofibers, were two methods employed to achieve such coatings. Dual drug loading in a single electrospun scaffold was also be attempted by a novel dual spinneret technique established by us. This scaffold was created as a potential wound healing dressing. This method of electrospinning enabled inclusion of larger quantities of two actives into the same scaffold. Such electrospun polymer fibers were directly deposited on microneedles and evaluated for drug release characteristics. It is expected that this novel drug delivery system will eventually allow immediate as well as sustained release of not only hydrophilic and lipophilic compounds but also high molecular weight compounds.Ph.D.Includes bibliographical references (p. 191-199)
Living apart together: Intimate Relationship across nations distance:Transnational Couples: Gender, Spirituality and Digitalisation
No full textIn the past decades the time honoured assumption that intimate couples stay under the same roof has been challenged, diverse forms of living arrangements are emerging where partners maintain separate residences, even across national borders. However, investigation of intimate relationship formation and maintenance across geographical borders is rather limited. This ongoing research project explores relationship among distant transnational couples, i.e. couples who are residing/ have resided in different countries (minimum one year), at least one of the partners in the Scandinavian context. Within a theoretical framework of gender related to emotional reflexivity (Holmes, 2014), spirituality and digital emotions, the history and dynamics of these relationships are explored, in the backdrop of transnationalism. In-depth interviews (face- to face and some online) dealing with the psycho- social aspects of togetherness and separation, visions about the future and suggestions to other distant couples are conducted with 20 couples/partners. The preliminary results show the challenges entailed in distant intimacy dynamics and their negotiations. The interactional state of being together and apart mutually enable and constrain each other in many ways. Quality time together, ‘fun’ memories construction, parting rituals, ‘systematic’ online contact, spiritual acceptance emerge as the resources. While the mobility costs (economic, temporal and affective), restrictive migration laws, pressure to have quality time, work/ life segmentation, social network related dilemmas emerge as burdens. However, being apart and together are intertwined for the transnational distant couples. The analysed ‘good practices’ will form the applied part for promoting the mental health and wellbeing of such couples.
