The use of chemicals in the textile industry is increasingly recognized as a problem and a matter of public concern. A proper EU policy on the subject is still missing. However, as testified by the number of self-organized communities and activist campaigns emerging around this theme, a demand for higher transparency is rising from the base of society. A kit made of a new label graphic; a hyperspectral camera and a mobile app have been design as a possible strategy to allow fashion companies to better meet the needs of their consumers. This final configuration opens up for a reflection about design practice, trust and transparency.

Gao, Ying. "Knowledge management in chemical process industry". Thesis, University of Surrey, 2005. http://epubs.surrey.ac.uk/842919/.
Testo completoAbstract (sommario):
Information and knowledge are among the major resources in chemical process enterprise. Effective knowledge sharing and decision coordination are important to collaborative product development and integrated manufacturing. The integration of knowledge management in chemical process industry can provide the enterprise an environment for knowledge sharing and coordinate decision-marking, it can also help the enterprise to realize the best value of its knowledge assets and make businesses more competitive and profitable. In this work, an Ontology-based knowledge management system is proposed for knowledge integration and decision support in chemical process industry. Information technology, artificial intelligence and chemical engineering domain technology are integrated into a unified system to support knowledge integration, cooperate manufacturing, enterprise management and information service in chemical process industry. The system infrastructure includes Ontologies, knowledge repository, information retrieving agent, knowledge discovery tools and user interface. Ontology plays an important role in the knowledge management system for knowledge integration, knowledge sharing and reuse. Ontology classifies the knowledge base, integrates sources of knowledge into the knowledge repository, supervise database and user interface construction, and severs as a backbone of the knowledge management system development. A flexible and systematic approach for ontology development and implementation is established in this work to support ontology creation and application in the knowledge management system. Knowledge retrieving services are developed in the knowledge management system to extract information and knowledge from various data sources. Information retrieving agents retrieve information from the knowledge repository according to the user's requirement, and provide cleaned information through information filtering. Ontology-based information retrieving approach is utilized in this work. Data mining technique is applied to extract the implicit and potentially useful information, and also predict trends by mining the historic data. Knowledge management in chemical process industry consists of a set of practices aimed at monitoring the process operation and providing decision support for the engineers and managers. However, currently available computer-aided systems for chemical process engineering are normally isolated, which make it difficult for data and information exchange and decision support. Multi-agent system is utilized in this work to coordinate these tasks and incorporate the disparate information resources. Process simulation, rule- base decision support, artificial intelligence such as artificial neural network (ANN) are integrated in this system for process analysis, data processing, process monitoring and diagnosis, process performance prediction and operation suggestion. A multi-agent system developed on the basis of JADE (Java Agent Development Framework) is integrated in the knowledge management system, in which software agents are designed to perform the tasks of process monitoring, process performance prediction, manufacturing management and information service. With a common communication language and shared ontologies, agents can communicate and cooperate with each other to exchange and share information, and achieve timely decisions in dealing with various enterprise scenarios. The implementation of knowledge management system will provide well-organized information for technical monitoring in chemical process industry, and enable the knowledge integration and sharing among researchers, engineers and managers. The application of the knowledge management system in chemical process industry can also help the engineers to coordinate in manufacturing execution, and provide decision support based on up-to-date information and knowledge.

La indústria química és un dels sectors productius on major i més àmpliament s'apliquen recursos d'I + D de totes les economies avançades. A més, la indústria química europea abasteix virtualment a tots els sectors de l'economia i representa un 17,8% de les vendes totals de productes químics en el món. Aquesta tesi doctoral ofereix una visió general del panorama industrial químic europeu així com de l'escenari canviant de la indústria química a nivell mundial. La investigació es centra en l'anàlisi de les dinou empreses químiques europees principals per oferir una idea sobre els problemes actuals als què s'enfronta el sector a Europa, especialment després de tenir lloc la crisi econòmica i mostrant com Europa i les pròpies empreses de referència estan invertint en I + D com a forma de superar els reptes actuals. La investigació mostra que la despesa en I + D al sector químic ha estat igual en els últims anys i és encara el major inversor de totes les activitats d'I + D. En termes d'inversió en I + D, BASF és l'empresa que ha realitzat més inversió, seguida de Bayer i Syngenta; encara que si s'analitza la intensitat de la inversió ha estat més gran en Syngenta i Bayer. BASF i Bayer són les empreses líders en l'aplicació de patents així com en el nombre de patents concedides. La qualitat de la recerca en el cas de les empreses químiques és molt alta. La majoria de les grans empreses europees realitzen la seva primera aplicació de patents a Europa, comparades amb la d’altres localitzacions geogràfiques. Totes les empreses químiques més importants estan utilitzant Merger & Acquisition (M & A) per accedir a la innovació. La col·laboració empresa-universitat és també una forma de generar innovació en la indústria química a Europa. La investigació també mostra que la regulació REACH està tenint un efecte negatiu en l'àrea d'innovació en la indústria química europea. Els clústers químics i la distribució geogràfica de les empreses químiques juguen igualment un paper significatiu en la generació de la innovació.La industria química es uno de los sectores productivos donde mayor y más ampliamente se aplican recursos de I+D en todas las economías avanzadas.

The chemical industry is one of the largest and most R&D- intensive manufacturing sectors in all advanced economies and European chemical industry supplies virtually all sectors of the economy and accounts for 17.8 % of the total chemical sales in the world. This thesis gives an overview of the European chemical industry and the changing scenario of the world chemical industry. The study focusses on the top nineteen chemical companies of this region. It gives an idea about the current problems this industry is facing in Europe especially after the economic crisis and shows how the region and the top companies are investing in R&D to bring innovation to overcome the current challenges. It shows that the R&D spending in this industry in absolute term has remained similar over the years and it is still globally the largest investor for the R&D activities. In terms of R&D Investment, BASF has been making the largest investment followed by Bayer and Syngenta while the R&D intensity is highest for Syngenta and Bayer. BASF and Bayer are the leader in patent application and number of granted patent. The quality of research in case of most chemical companies is very high. Most of the large European company makes their first patent application in Europe compared to other Geographical location. All the large chemical companies are using Merger & Acquisition (M&A) to gain access to innovation. Industry-academia collaboration is a way to generate innovation in chemical industry in Europe. The study also shows that REACH regulation is having a negative impact on innovation in European chemical industry. Chemical clusters and geographical distribution of the chemical companies play a significant role in generating innovation.

La question principale que dispose cette thèse est relative à la restructuration du secteur et des entreprises chimiques à cause des nouvelles frontières stratégiques, notamment concurrentielles, technologiques, financières et institutionnelles. L’objectif principal c’est de comprendre et caractériser les comportements hétérogènes des firmes chimiques, les en classent en groupes distincts. La première prémisse de cette thèse est que l'apprentissage cumulatif scientifique ou les DPI (droits de propriété intellectuelle) ne sont plus les principaux obstacles aux nouveaux entrants dans le secteur; elles ont été additionnées à la suprématie des finances, certifications HQES (santé, qualité, environnement, sécurité ) et les valeurs intangibles (la marque, la chaîne d'approvisionnement, réseau, les clusters, la compréhension des clients, le marketing, la responsabilité sociale, la gestion et de main-d'œuvre qualifiée). Le second postulat c’est que l’environnement concurrentiel et technologique a recrée des nouveaux limites stratégiques en partagent les firmes en sous-secteurs comme les sciences hybrides, sciences de la vie, substances de base ou les produits chimiques spécialisés. Cette nouvelle configuration induit les opérations de l'acteur dans leur portefeuille de produits, leurs actifs, production, R&D, F&A, réseau, JV, alliances, licences, connaissances spécifiques et le marketing. L’hypothèse soutenue c’est que les changements dans le secteur chimique évoluent dans un cadre nouveau avec les principaux vecteurs : mondialisation concurrentiel, création de la valeur, restructuration du marché et la réglementationThe principal matter that disposes this thesis is concerning the changes in the chemical firms for “new strategic boundaries”. The main objective is to understand and characterize the heterogeneous chemical companies’ strategies and to classify in distinct groups. The first premise of this thesis is that the accumulative scientific learning or IPR (Intellectual property rights) is not anymore the main barrier to new entrants into the segment; it was replaced by finance supremacy, HESQ (health, environmental, safety and quality) certifications and intangible values (brand, supply chain, network, clusters, customer understanding, marketing, social responsibility, management and skilled labor). Several new players appeared supported by national governments and using licensees or technologies from specialized engineering firms (SEF), raw material suppliers & equipment fabricators to produce locally and replace imported products, furthermore those new players through foreign direct investment( FDI), merger & acquisition (M&A) or joint ventures (JV) expand their operations abroad in direct concurrence with the traditional groups. Second premise is that the latest competitive environment are recreating new strategic firms’ boundaries separated in sub sectors like hybrid science, basic or specialty chemical inducing the main player’s actions in product portfolio , fixed assets, process, R&D , M&A, network, JV, alliances, licenses , knowledge capital and marketing. The thesis concludes that the changes in the chemical sector evolve inside a new framework typify at 4 main axes: value creation, globalization, restructuring and regulation

Testo completoAbstract (sommario):
A high demand of both electricity and heat exists in Arizona Chemical (a chemical plant dedicated to the distillation of Crude Tall Oil) for production processes. Due to the rising cost of resources and electricity, more and more companies are trying to decrease the energy expenses to increase their competitiveness in a global market, thus increasing their profit. Some companies look at their energy consumption in order to diminish it or to explore the opportunity to generate their own and cheaper energy. In companies where the production of steam already takes place, cogeneration can be a good solution to palliate the cost of the energy used. This study addresses this issue through three actions such as the characterization of the boiler, a better steam flow measurement grid and the generation of electricity. The first one addresses the state of one of the key parts of steam production, the boiler, through the calculation of its efficiency with two different methods (direct and indirect calculation). These methods require some measurements which were provided afterwards by the company supervisor. This will allow the company to identify the weaknesses of the boiler to be able to improve it in the future. The second one aims to improve the knowledge about the steam system. New flow measurement points were suggested after doing an analysis of the current controlled flows to have a better overview outline of the steam use.The third one studies the generation of electricity with a Rankine cycle. The limitations in the characteristics of the steam were identified and different configurations are proposed in accordance to the restrictions identified. An efficiency of 93% is obtained for the boiler with the direct method and 82.3 % for the indirect one. The difference between them can be explained by the use of datafrom different time frames for both methods. The main contributors to the losses are the ones related to the dry flue gas and the hydrogen in the fuel. In the current status only 40% of the steam flows are identified, a number which is expected to raise with the new measurement points. It was not possible to estimate the effect of the new points due to the desire of the company to not disturb the current production. Due to the fuel price the production of steam for only electricity was not profitable and instead the generation of both electricity and heat from the same steam is proposed. This integrated system is now possible to implement due to its low payback time (2.3 years). This solution can generate 758 kW of electricity and provide the company with 6437 MWh of electricity each year. Then, the effect of the variation of different variables over the performance of the cycle were studied: different electricity prices, steam rate production, fuel cost and the state of the condensate recovery were discussed. The variation of both the condensate recovery and fuel cost did not affect the payback time due to their costs being neutralised by the revenues obtained from them. The variation of the electricity prices and steam production affects the payback but due to the high revenue that is expected it does not hamper the good nature of the investment. The generation of electricity is recommended due to the low payback time obtained. The different variations studied in the system did not change the payback time notably and showed that the investment is highly profitable in all the scenarios considered. The use of two smaller turbines instead of the one chosen (with a maximum rated power of 6 MW while only 758 kW is generated with the proposed solution) should be studied since the turbines would work closer to their maximum efficiency.

Testo completoAbstract (sommario):
This study examines the processes of collaboration between universities and industry at the level of the organizations involved. In particular, it considers (1) the influence that certain characteristics of universities and companies have upon their willingness or ability to collaborate with each other; upon their objectives for collaboration; and upon their choices of specific forms of collaboration; (2) the relationship between forms of collaboration and objectives for collaboration; and (3) the process of collaboration and the relative success of such collaborations. Three different research instruments were used; a series of interviews with liaison officers in universities and companies; a survey of companies and universities ( the chemical and allied products industry and chemistry university departments in the UK); and detailed studies of research projects sponsored by companies. Willingness to collaborate, the nature of the objectives and preferences for certain forms of collaboration were found to depend upon overall size and size of R&D in the case of companies. However, the evidence suggests that although different university departments may have different objectives or prefer different forms of collaboration, the wiilingness to collaborate is common to all departments. Three factors emerge as important for the performance of collaborative projects; a good working atmosphere, collaboration in the definition of the project and joint planning. Some factors which have been frequently suggested in the literature (e.g. product 'champion') were not observed. Finally, underestimation of technical difficulties proved to be one of the main reasons for low performance.

Perricane, Lisa Helen. "County Demographic Influence on Toxic Chemical Activities of Chemical-Related Industry in Michigan". ScholarWorks, 2015. https://scholarworks.waldenu.edu/dissertations/1420.
Testo completoAbstract (sommario):
There are a large number of chemical facilities that emit toxic chemicals in Michigan, and there is a concern regarding toxic chemical exposure to the residents of Michigan counties. However, it is uncertain whether chemical companies that emit toxic chemicals in Michigan are influenced by county demographic factors in deciding whether to engage in voluntary pollution prevention (P2) activities and whether this decision influences U.S. Environmental Protection Agency's (U.S. EPA) Risk-Screening Environmental Indicators (RSEI) scores. Using Bullard's theory of environmental justice, the purpose of this quantitative study was to determine if there was a correlation between chemical-related industry's voluntary P2 participation, U.S. EPA's RSEI scores for chemical-related facilities, and demographic factors in Michigan counties between 2007 through 2011. A cross-sectional design using hierarchical multiple regression analysis was used to study potential environmental inequality in 20 Michigan counties. Publically available data from the U.S. Census Bureau and the U.S. EPA included demographic data, voluntary P2 participation data, and RSEI scores for 20 counties in Michigan. A statistically insignificant correlation was found between voluntary P2 participation and median annual RSEI scores of Michigan industry; while a statistically significant, inverse correlation was found between median annual RSEI scores and educational attainment. The results from this study can be used by policy makers to promote more effective voluntary P2 policy and to create county-specific public education programs promoting toxic chemical awareness that will lead to positive social change in Michigan.

Testo completoAbstract (sommario):
In a questionnaire survey of the UK chemical manufacturing industry, this report investigates the views of these companies on economic and monetary integration of Europe. More specifically, the question of whether or not these companies would like to see a UK membership of the European Economic and Monetary Union (EMU) is asked, following a more thorough questioning aimed at examining the underlying reasoning behind their viewpoints. The findings show a two-to-one majority on the side of a positive stance towards a UK participation in this final stage of integration of the European marketplace, and support theory in its belief that strong incentives for such a view include removal of exchange rate uncertainty, and elimination of transaction costs. Additionally, and also in accordance with the collected theoretical framework, larger companies, and companies with high levels of exports, are found to have a greater desire for a UK EMU membership. Findings in contrast with theory include that of a lack of correlation between high levels of imports and a desire for integration, as well as a lack of belief in increased inflow of foreign investment as a prospective benefit of membership in the questioned population. Correlations found between the main question and the removal of exchange rate uncertainty and elimination of transaction costs were very strong, but positive statistical determination for the absence of chance in creating the associations could not be made, due to the small scale of the survey, creating response alternatives with less than five accumulated responses

Testo completoAbstract (sommario):
PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIROA indústria química ocupa posição de destaque em todo o mundo e no Brasil é um dos setores industriais que mais contribuem para o PIB. A química está presente em praticamente todos os setores e produtos utilizados pelo homem e, cada vez mais, contribui com soluções para a melhoria da qualidade de vida da população. Entretanto, alguns riscos são inerentes aos processos fabris e devido a acidentes de grandes proporções no passado (ex. Bhopal na Índia em 1984) o setor decidiu implantar um programa de alcance mundial denominado Responsible Care, destinado a minimizar os riscos e eventuais conseqüências de acidentes. Grande progresso resultou então na gestão das indústrias e os temas saúde, segurança e meio ambiente passaram a ter importância na tomada de decisão, equilibrando com as preocupações meramente econômicas. No Brasil o programa foi lançado em 1992 pela Associação Brasileira da Indústria Química (ABIQUIM), tendo sido revisado profundamente no último ano para ficar alinhado com os temas Desenvolvimento Sustentável e Responsabilidade Social Empresarial e assim, promover a busca de resultados econômicos, ambientais e sociais de forma equilibrada. O presente estudo busca avaliar que motivações as empresas tiveram para adotar uma postura de Proteção Ambiental e de Responsabilidade Social e até que nível da organização esse compromisso conseguiu permear. Foram pesquisadas as associadas da ABIQUIM, representando 90% da produção de químicos no Brasil e tomados depoimentos em indústrias líderes de modo a responder às questões colocadas.
Chemical Industry is located in a high position around the world and particularly in Brasil, where is one of the major contributors to GNP. Chemistry is presented at all sectors and mankind used products and more and more contributes with solutions to improve quality of life. Though, there are some inherent risks at manufacturing processes and due to major accidents in the past (e.g. Bhopal in 1984), the sector decided to implement a global program, so called Responsible Care, aiming to minimize risks and consequences of eventual incidents. A lot of progress happened in the management field and health, safety and environment started to be considered as important in the decision process, together with economic considerations. Brazilian Chemical Industry Association (ABIQUIM) launched the program in 1992, which has been deeply reviewed last year in order to in alignment with Sustainable Development and Corporate Social Responsibility concepts and to promote the triple bottom line search. This dissertation is intended to identify the motivations that lead industries and executives to adopt Environmental Protection and Corporate Social Responsibility and how deep this commitment has penetrated in the structures. Members of ABIQUIM have been researched and executives have been interviewed in order to have answers to these questions.

Wan, Yoke Kin. "Synthesise a sustainable sago industry". Thesis, University of Nottingham, 2016. http://eprints.nottingham.ac.uk/33818/.
Testo completoAbstract (sommario):
Various sago biomass (i.e., sago barks, fibres and wastewater) that potentially converted into value-added products are generated during sago starch extraction process (SSEP). In current industrial practices, such biomass are disposed to the environment and caused severe environmental issues. Therefore, in order to minimise the environmental impacts and to improve economic performance of sago industry, sago biomass is vital to be recovered. On the other hand, a sustainable sago value chain, which involved activities plantation, harvesting, sago starch extraction process (SSEP), and transportations, is synthesised in this thesis via Fuzzy Multi-Footprint Optimisation (FMFO) approach. This proposed approach considered carbon, water, and workplace footprints as well as economic performance of sago value chain. In order to trade-off the conflicts among the optimisation objectives, the concept of fuzzy optimisation is adopted in this approach. Then, recovery of sago biomass in SSEP is focused. In order to prioritise sago biomass for recovery in sago industry, Material Flow Cost Accounting (MFCA)-based prioritisation approach is developed in this thesis. This MFCA-based approach introduced hidden cost (HC) and carry-forward cost (CFC) to determine cost associated with waste streams. Based on the associated cost, waste streams can be prioritised for recovery. Then, this MFCA-based prioritisation approach is further extended as extended MFCA (eMFCA)-based approach to simultaneous synthesise total resource conservation network (RCN) with industrial processes. In this thesis, total water network and SSEP is synthesised simultaneously via eMFCA-based approach. Furthermore, techno-economic and environmental performance of conversion of sago barks and fibres into combined heat and power (CHP) and bioethanol is evaluated. In addition, sensitivity analysis on payback period is conducted in different scenarios due to variation of feedstock cost, enzyme cost, and labour cost. In order to further improve sustainability of sago industry, a conceptual integrated sago-based biorefinery (SBB) is envisaged. Maali’s method is adopted in this thesis to allocate the benefits of each party participating in integrated SBB. Lastly, conclusions and future works are included in the end of this thesis.

Donnelly, James F. "Chemical education and the chemical industry in England from the mid-nineteenth to the early twentieth century". Thesis, University of Leeds, 1987. http://etheses.whiterose.ac.uk/500/.
Testo completoAbstract (sommario):
The thesis examines the relationship between formal education and the chemical industry from about 1850 to about 1920. It first surveys relevant literature and discusses historiographical and definitional matters. It then sketches aspects of the relationship between science, education and technique during the early nineteenth century. It moves on to explore the representation of that relationship during the period of the thesis proper. It argues that this was dominated by a view articulated largely by academic chemists from the mid-century. Industrial relevance was exploited as a means of promoting research and teaching. This, rather than an 'objective' analysis, influenced the view which was promoted. Alternative, more directly technical, approaches were envisaged by some industrialists. At the turn of the century a complex negotiation was in progress, focusing on the place of technological disciplines in academe. Attempts to establish chemical technology curricula in the nineteenth century are surveyed. Reasons are suggested for their failure, particularly the difficulties in publicly transmitting and creating commercially sensitive knowledge and the pressures of curricular and institutional hierarchies. By contrast curricula in 'pure' chemistry were numerically successful. The thesis examines the recruitment of chemistry students by the industrial and educational sectors. It surveys the occupations of a sample of students from a range of English institutions. It concludes that industrial recruitment had a greater role than has been suggested by some scholars. The recruitment and employment of trained men in a number of chemical firms is surveyed, and it is concluded that their main role was in routine analysis. Expansion of this activity was slow, involving vertical routes into managerial positions rather than functional specialization and bureaucracies. A class of technically-trained routine analysts was created. The growth of chemical engineering as academic field and occupation is examined. The roles of academics and industrialists in conceptualizing the field around 'unit operations' are discussed. An account is given of the emergence of the Institution of Chemical Engineers.

Larsson, Robert. "Integrating sustainability with business strategy – the Swedish chemical industry". Thesis, Stockholm University, Stockholm Resilience Centre, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:su:diva-7826.
Testo completoAbstract (sommario):
This thesis aims to investigate perceptions of sustainability in relation to business
strategy within the Swedish chemical industry. To this end, a survey was
distributed with the assistance of industry organization Plast- och Kemiföretagen
to companies that are part of the Responsible Care® program.
A second purpose of the study is to explore critical factors when implementing an
integration of sustainability with business strategy. To do this as well as dig deeper
into a couple of questions raised in the survey, a qualitative study was carried out
at Akzo Nobel business unit Pulp and Paper Chemicals (operating under the brand
name of Eka Chemicals). Semi-structured interviews were performed with seven
company representatives from different organizational levels, to explore critical
factors identified in a literary study.
From the survey, it could be concluded that the studied companies considered
sustainability as an important issue today and with growing importance for the
future. It was also observed that sustainability is currently not an issue at the core
of business strategy, as 35% of respondent companies did not think that top
management handled issues related to sustainability. Enhanced reputation and
cost reduction/resource efficiency were seen as the primary creators of business
value when addressing sustainability. Additional top motivating forces to consider
sustainability were legislative demands and company core values.
From the literary study a model of critical factors when implementing changes in
strategy was developed. Four different aspects identified were explored in the
semi-structured interviews at Eka Chemicals: change leadership, shared vision,
sense of urgency and aligning goals. In that specific setting, the critical factors of

Introduction Production employees within the UK fragrance industry are exposed to large quantities of chemical substances and mixtures over working shifts. Occupational respiratory exposure within this industry is managed in line with relevant legislation and guidelines. There is a lack, however, of published literature studying the effects of respiratory exposure to chemicals on fragrance production employees. A multi-site cross-sectional study was conducted using employees from the UK fragrance industry. The primary aim was to answer the research question: In fragrance industry employees, is occupational respiratory exposure to chemicals linked to a statistically significant change in lung function as measured using spirometry? The secondary aim was to use the data acquired to develop a weighted questionnaire that is predictive for potential lung function problems, for use as a preplacement occupational health tool within the fragrance industry. Methods A cross-sectional study was designed, using an exposed group (fragrance production and associated functions, n = 60) and a control group (non-exposed fragrance industry employees, e.g. office staff, n = 52). 5 UK companies took part, giving a total of 112 participants. This was calculated as sufficient to achieve 80% power and 5% significance. Spirometric measurements (FEV1, FVC and PEF*) were taken pre-shift and postshift.Information was provided by participants for information on potential confounding factors (smoking, personal or family history of respiratory problems, body mass index). Post-shift measurements were compared between groups, using analysis of covariance (ANCOVA) to adjust for the baseline pre-shift measurements. A pilot questionnaire was developed. The weightings for each of the questions contained within the questionnaire were found by performing simple and multiple linear regression on the spirometric and demographic data. The unstandardised coefficient (B) was used as a measure of effect size in order to calculate a weighted score for each question response. * FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity; PEF = peak expiratory flow Results Adjusted mean difference in post-shift measurements between groups (exposed vs. control) for each outcome measure was NOT observed to be statistically significant. Adjusted p-values for FEV1, FVC and PEF were 0.722, 0.883, and 0.676, respectively. Internal validation checks showed that the weighted questionnaire scores correlated with FEV1 measurements, with a high score correlating with a reduced FEV1 performance. Further validation is necessary to determine a threshold score corresponding to FEV1 of <80 predicted, the lower limit of normal for FEV1 performance. Conclusions The present study showed no significant effects of occupational respiratory exposure on the spirometric performance of the study population. On first inspection the present findings support the suggestion that protective measures in place in the fragrance industry are sufficient in minimising occupational risk to respiratory health. Further validation of airway hypersensitivity measurement methods used in spirometry and the questions asked in the questionnaire is vital in order to determine a threshold score corresponding to FEV1 of <80%predicted, the lower limit of normal for FEV1 performance. The pre-placement occupational health questionnaire has potential to be employed as a predictive tool for potential lung functionality in fragrance industry employees, subject to further development. Subsequent external validation in future studies will be required before the questionnaire can be released for widespread use. In conclusion, this work is the first step in a novel area of research, and the industry would benefit from the follow-up or expansion of this research.

The company sponsoring our project is a leading chemical manufacturer, supplying a wide range of products on a global scale. One of the most interesting lines of business the company operates is to supply specialty chemicals in faraway places on few weeks' notice. The nature of these supply chains is project- driven, or, in other words, unique, non-repeatable and established for the sole purpose of fulfilling a single project. The company faces the challenge of operationalizing the set-up of such supply chains in order to reduce the amount of time and effort devoted to each supply and maximize learning from each project. This thesis seeks to address the conundrum of setting up project-driven supply chains in a more efficient, effective and easily repeatable way. Through interviews with company personnel, we identify eleven challenges and subdivide them into three categories: Business-Specific, Cross-Border, and Last-Leg. Next, through literature review and interviews with experts, we identify seventeen possible solutions to the above issues, which have the potential to improve planning and execution of project-driven supply chains in the chemical industry. Recognizing that cross-learnings from supply chains in humanitarian and military supply chains are valuable, our interviews include military and humanitarian practitioners, with the aim of increasing the variety of solutions. Using the research data as a basis, we formulate a project-driven supply chain mobilization template aimed at including most critical areas required in setting up project-driven supply chains. This template could be used as both a guideline for planning the mobilization of a supply contract, and as a validation tool to confirm the mobilization process has been thoroughly completed. The adoption of the mobilization template and process via integration with managerial and approval processes is expected to drive a more efficient and effective mobilization of project-driven supply chains for companies within the chemical industry and beyond.

Testo completoAbstract (sommario):
This research was concerned with identifying factors which may influence human reliability within chemical process plants - these factors are referred to as Performance Shaping Factors (PSFs). Following a period of familiarization within the industry, a number of case studies were undertaken covering a range of basic influencing factors. Plant records and site `lost time incident reports' were also used as supporting evidence for identifying and classifying PSFs. In parallel to the investigative research, the available literature appertaining to human reliability assessment and PSFs was considered in relation to the chemical process plan environment. As a direct result of this work, a PSF classification structure has been produced with an accompanying detailed listing. Phase two of the research considered the identification of important individual PSFs for specific situations. Based on the experience and data gained during phase one, it emerged that certain generic features of a task influenced PSF relevance. This led to the establishment of a finite set of generic task groups and response types. Similarly, certain PSFs influence some human errors more than others. The result was a set of error type key words, plus the identification and classification of error causes with their underlying error mechanisms. By linking all these aspects together, a comprehensive methodology has been forwarded as the basis of a computerized aid for system designers. To recapitulate, the major results of this research have been: One, the development of a comprehensive PSF listing specifically for the chemical process industries with a classification structure that facilitates future updates; and two, a model of identifying relevant SPFs and their order of priority. Future requirements are the evaluation of the PSF listing and the identification method. The latter must be considered both in terms of `useability' and its success as a design enhancer, in terms of an observable reduction in important human errors.

The thesis describes and analyses a long-term transformative change program conducted at ICI (Australia) Botany Site between the years 1987 - 1997. The change program is unusual in that, after a massive and destructive confrontation between management and the unions, a new collaborative approach to change was developed which led to significant organisational renewal. Change interventions developed in the program have diffused through Australian industry over the decade. The program is analysed within the framework of a theoretical model which describes a path taken towards achieving a capable organisation which can sustain productive performance. The thesis uses evidence from the case to investigate issues of management style, governance, flexibility, 'bundled interventions', productivity, work organisation, downsizing, reward systems, skills acquisition and self-managed teams. A theoretical model of organisational change is developed which suggests how the treatment of these contingencies can lead to organisational capability.

Testo completoAbstract (sommario):
Organisations across the world are faced with the same challenges of how to get employees
to be totally immersed in their role at work. People occupy roles at work. There is no sense in
engaging employees if management is not going to invest in the effort of placing these
employees in appropriate roles and supporting them to be engaged in their work. There are
generalised states that employees occupy: people are to some degree job involved, committed
to organisations, or alienated at work in the form of self-estrangement. These concepts
suggest that employees can use varying degrees of themselves, physically, cognitively and
emotionally, in the roles they perform.
The primary objective of this research was to explore the three psychological processes,
meaningfulness, safety and availability to be determinants of work engagement. Another
objective was also to explore the influence of the antecedent conditions, namely work role fit,
co-worker relations, supervisor relations, co-worker norms, self-consciousness and resources
on work engagement. The study also investigated whether the psychological processes
mediate the relationships between antecedent conditions and work engagement.
A survey design was used to reach the research objectives. The specific design used was the
cross-sectional design. Employees across all levels (N=165)i n a chemical industry in the
Vaal Triangle were targeted for this research. Four standardised questionnaires were used in
the empirical study, namely the Psychological Processes Questionnaire, Antecedent
Conditions Questionnaire, Work Engagement Questionnaire as well as a Biographical
Questionnaire.
Multiple regression analyses showed that psychological meaningfulness mediated the
relationship between work role fit and work engagement. A total of 32% of the variance in
psychological meaningfulness was predicted by work role fit. Psychological meaningfulness
predicted 29% of the variance in work engagement. Psychological availability mediated the
relationship between available resources and work engagement. The analysis indicated that 11% of the variance in engagement was predicted by resources. Psychological availability
predicted 3 1 % of the variance in engagement.
Recommendations for future research were made.Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.

In a new world of work characterised by competitiveness, benchmarking, technological innovation and efficiency, the South African chemical industry needs to function at an optimal level to meet the demands of its stakeholders and employees. The industry needs leadership of the highest standard and an efficient, productive workforce.
The objective of this study was to determine the relationship between leader empowering behaviour, self-efficacy, job resources and work-related flow for employees in the chemical industry. More specifically, it was examined whether personal and organisational resources facilitated flow at work, and whether employees who experienced flow mobilised more resources over time.
The research method consisted of a literature review and an empirical study. A cross-sectional survey design was used to collect the data. An availability sample (N= 213) from employees in the chemical industry was taken. A biographical questionnaire and a self-constructed instrument (JDRS) were used to measure the unique job demands and job resources in the chemical industry. Along with the JDRS, the WOrk-reLated Flow Scale (WOLF), the Leader Empowering Behaviour Questionnaire (LEBQ) and General Perceived Self-efficacy Questionnaire (GPSQ) were used as measuring instruments. The statistical analysis was conducted with the help of the SPSS program.
The results of the research indicate that the availability of leader empowering behaviour (i.e. delegation of authority, self-directed decision making, information sharing, and coaching for innovative performance), self-efficacy and job resources (i.e. supervision, availability of resources and autonomy) can result in higher levels of work-related flow in the workplace.

In order to stay competitive in an economic landscape characterised by constant turmoil and change, organisations in the chemical industry are engaging in various adaptive strategies like mergers, acquisitions and diversification. Adaptation strategies may vary but they all have similar results in common, one of which is the exposure of employees to feelings of uncertainty and job insecurity. Identifying factors that enable employees to effectively deal with job insecurity is becoming an increasingly important topic for research. The primary objectives of this research were to investigate the relationship between job insecurity, general health and organisational citizenship behaviour of employees in a chemical industry, as well as to determine whether self-efficacy mediates the relationship between job insecurity and general health on the one hand and between job insecurity and organisational citizenship behaviour on the other hand. The research method consists of a literature review and an empirical study. A cross-sectional survey design was used to collect the data. An availability sample (N = 205) was taken from employees in a chemical industry. The Job Insecurity Questionnaire (JIQ), General Health Questionnaire (GHQ), Organisational Citizenship Behaviour Scale (OCB), General Perceived Self-Efficacy Scale (GPSES) and a biographical questionnaire were administered. The statistical analysis was carried out with the SPSS program. Principal component factor analysis confirmed a two factor structure for job insecurity consisting of affective job insecurity and cognitive job insecurity. Factor analysis resulted in three factors for general health, namely psychosomatic symptoms, severe depression and social dysfunction. The two factors of the OCB were confIrmed and were labeled altruism and compliance. The unidimensional structure of the GPSES could also be confirmed and was labeled self-efficacy. All scales indicated acceptable reliability with Cronbach alpha coefficients varying from 0,70 to 0,89. Spearman product-moment correlations indicated a statistically positive correlation (practically significant, medium effect) between cognitive job insecurity and affective job insecurity. Results further indicated that an increase in psychosomatic symptoms will lead to an increase in severe depression and social dysfunction, while an increase in severe depression will be associated with an increase in social dysfunction. It was found that when altruism increased, self-efficacy will also increase.
The hypothesised mediating effect of self-efficacy was only partially demonstrated for the relationship between affective job insecurity and general health, as demonstrated by severe depression. Self-efficacy was further shown to mediate the relationship between cognitive job insecurity and altruism. The relationship between cognitive job insecurity and affective job insecurity as dependent variables and compliance as an independent variable were partially mediated by self-efficacy. MANOVA analysis indicated that female employees experienced higher levels of cognitive job insecurity than male employees. White employees and employees with a degree exhibited more organisational citizenship behaviour, as demonstrated by compliance. Results further indicated that African employees and employees with a qualification of up to Grade 11 experienced higher levels of severe depression.

Testo completoAbstract (sommario):
A new approach to the fabrication of polymeric thin films is presented. This approach, chemical vapor copolymerization (CVcP), has all the advantages of chemical vapor polymerization (CVP), including exceptional purity, highly conformal coatings, continuous films even when very thin, low stress, and low environmental impact. The range of film properties available by CVcP is much greater than by CVP.
A specially modified deposition system was constructed to study deposition kinetics. A model was developed which allowed quantification of the order of initiation of paraxylylene (PX), which is the initiation system for all the work reported here. This model suggests a trimer diradical is the smallest stable diradical species formed by PX at room temperature, confirming thermodynamic predictions.
This system also allows the calculation of reactivity ratios of PX with vinylic comonomers. A model is developed in which reactivity ratios can be determined if the following quantities are known: a) thickness vs. position of the final film; b) partial pressures of each reactive species entering the deposition chamber and c) composition vs. position in the final film. This model was tested yielded reasonable values for reactivity ratios.
A polymeric film extremely low in refractive index (1.38-1.39 in the visible region) is presented. This film is formed by copolymerizing poly(parachloroxylylene), or PX-C, with perfluorooctyl methacrylate (PFOMA). The refractive index of the homopolymers, by contrast, are in the 1.60-1.68 range. Film growth rates are very low for this new material.
Finally, a new deposition procedure is introduced in which a comonomer with a low vapor pressure is codeposited with PX. The reactor temperature is above the ceiling temperature of PX deposition, but at a temperature where the comonomer can condense. This makes the deposition environment extremely rich in comonomer, yielding films whose final properties are nearly identical to films composed entirely of the comonomer. The procedure is demonstrated using n-phenyl maleimide (NPMI) as a comonomer; films produced had thermal stabilities nearly matching those of poly(NPMI). This procedure has great promise for broadening the use of polymeric thin films in the microelectronics industry, as well as other fields.Ph. D.

Lack of employee engagement in the workplace is one of the leading causes of lost productivity in the United States, estimated to cost organizations between $450 to $550 billion per year. The purpose of this single case study was to explore the strategies that some business managers in the chemical industry use to engage employees and increase productivity. The population for the study consisted of 5 small chemical business managers of a chemical company in the northeastern United States that demonstrated success in engaging employees. The conceptual framework for the study was social exchange theory. Data were collected from small business managers via semistructured interviews detailing participants' strategies in engaging employees in the workplace and from company physical artifacts such as website, posters, bulletins, and signage. The collected data were transcribed, and member checking was completed to validate the credibility and trustworthiness. Yin's 5-step data analysis process for a case study and the main words in context analysis were used to analyze data. Three themes discovered in the study were: leadership support, effective communication, and recognition and reward. The findings from this study revealed that chemical business managers used strategies to influence employee engagement in the workplace. The impact of positive social change includes providing insights for managers on strategy implementation for employee engagement in the workplace to increase organizational productivity and stability, which could lead to a healthy economy in the community and employees contributing positively to communities and supporting their families.

Testo completoAbstract (sommario):
Nanofiltration membrane elements have been employed for the treatment of solutions containing raw brine generated by chloralkali industry. This study focused on the selection of appropriate nanofiltration membrane element and the assessment of their performance for the removal of sulfate and the retention of chloride from feed solutions. The influence of membrane type, temperature, pressure and sodium sulfate concentration on the selective removal of sulfate from concentrated sodium chloride brines were investigated. A high passage of sodium chloride and rejection of sodium sulfate were achieved with two different commercial nanofiltration membrane elements, DL2540 produced by GE Osmonics and NF270-2540 manufactured by FilmTec (Dow), suggesting that both membranes can be employed in sulfate removal from sodium chloride brines for chloralkali industry. Operating pressure and temperature showed no significant effects on sulfate rejection under the tested conditions. However permeate flux increased with both temperature and pressure in the tested ranges. The influence of temperature on permeate flux was due to the dependency of the viscosity of salt solution, which follows the Arrhenius model. Sodium concentration in feed had significant effects on permeate flux, sulfate rejection, and sulfate concentration at membrane interface and in permeate. Sulfate rejection and permeate flux reduced sharply with the increase of sulfate concentration in feed.

Includes bibliographical references.The coal mining and processing industry in South Africa is responsible for significant local and regional environmental impacts, most notably those on water quality. As a result, legislation is becoming more stringent, public concerns are increasing and mine rehabilitation costs, which are incurred by the mining companies, are increasing. In response to this, the coal mining industry is recognising the importance of proper environmental management. However, the focus is still largely on end-of-pipe solutions. Cleaner Production (CP), which is a continuous preventative approach to environmental issues, has been demonstrated to be a cost-effective means of reducing wastes, increasing process efficiencies and improving the resource utilisation of coal mines in several countries, as well as of certain South African industries. It is therefore expected that Cleaner Production can provide the South African coal mining industry with an efficient, cost-effective approach to minimiSing its environmental footprint, and to meeting present and future legislation. This thesis aims to investigate whether this is in fact the case, by investigating and proposing feasible CP interventions for the coal mining industry.
