A comparative study of the resilience of coal logistics chains in Australia, South Africa and Canada

Au cours des dernières années l'industrie du charbon a connu un essor important. L'importance du charbon dans l'économie mondiale provient d'une demande mondiale soutenue et de niveaux de production en hausse constante. De ce fait, le nombre élevé d'importateurs et d'exportateurs est à l'origine d'un système d'échange complexe où la compétition est féroce. En effet, un nombre grandissant de pays importateurs se partagent les sources d'approvisionnement tandis qu'un nombre limité de pays exportateurs s'efforcent de répondre à la demande tout en essayant de s'accaparer le plus de parts du marché mondial. L'objectif de cette recherche s'inscrit dans ce contexte en démontrant les bénéfices associés aux chaînes logistiques résilientes pour tout acteur de l'industrie soucieux de devancer la compétition. Une analyse de la logistique de l'industrie du charbon permet entre autres de se pencher sur les questions suivantes: Comment les infrastructures influencent-elles la résilience d'une chaîne logistique? Quels risques est-ce que les catastrophes naturelles présentent pour une chaîne logistique? Comment la gouvernance influence-t-elle la résilience d'une chaîne logistique? Une chaîne logistique représente le trajet effectué par un bien ou produit au cours de son cycle de vie, du point d'origine au point de consommation. Ceci étant dit, le meilleur moyen de régler les problèmes inhérents aux chaînes logistiques est de maintenir de hauts niveaux de résilience. Cette recherche évaluera donc la résilience de chaînes logistiques du charbon des industries australienne, sud-africaine et canadienne. Pour ce faire, trois variables seront étudiées: les infrastructures, les catastrophes naturelles et la gouvernance. La comparaison des trois cas à l'étude se fera par un nombre défini d'indicateurs (12 au total) pour chacune des variables étudiées. Les résultats de cette recherche démontrent que la résilience des trois cas à l'étude se ressemble. Cependant, certaines chaînes logistiques détiennent des avantages comparatifs qui améliorent grandement leur résilience et leur compétitivité. Plusieurs sujets de recherche pourraient être utilisés pour compléter cette recherche. L'analyse comparative pourrait être appliquée à d'autres chaînes logistiques pour vérifier la viabilité des résultats. Une analyse semblable pourrait également être entreprise pour le secteur en aval de la chaîne logistique. Finalement, une méthodologie basée sur des interviews pourrait ajouter un regard différent sur les questions abordées.

Les articulations de l'arabité et du genre à travers les chaines d'équivalence : le cas de Uprising of Women in the Arab World

Ce mémoire de maîtrise s’intéresse aux nouvelles expressions protestataires qui ont émergé après les soulèvements connus sous le « printemps arabe » en prenant, comme objet d’analyse, Uprising of Women in the Arab World (UWAW), une page Facebook qui œuvre pour les droits des femmes à travers le « monde arabe ». Ce travail propose de saisir cette page Facebook à travers les croisements d’enjeux d’arabité et de genre, dans une perspective discursive critique. La notion d’arabité désigne une appartenance commune au « monde arabe » qui reposerait sur la production de référents religieux et linguistiques partagés par l’ensemble des pays arabes. Le genre est abordé comme un langage privilégié pour signifier les rapports de pouvoir (Scott, 1988). Afin de mettre en lumière les différentes intersections de l’arabité et du genre, je propose de recourir au concept d’articulation (Hall, 1980). Ce dernier réfère à l’assemblage de différentes pratiques de production qui constituent un discours. Cette mise en relation, non-nécessaire, s’effectue dans une conjoncture régie par les forces hégémoniques du moment. Ainsi, le concept d’articulation permet d’explorer ce que font dans leur (co)présence les discours hétérogènes par et dans lesquels l’arabité et le genre sont rendus visibles dans et à travers la page UWAW. Ces articulations sont questionnées à partir du concept de chaine d’équivalence de Laclau (2008) qui désigne une condensation de revendications hétérogènes, à travers des relations d’équivalence et de différence. Ces dernières se produisent à travers l’affirmation des particularités des revendications, tandis que les relations d’équivalence sont basées sur la mise en avant de la communalité des revendications. Cette recherche est guidée par la proposition de recherche suivante : UWAW peut être comprise comme un espace discursif traversé par des chaines d’équivalences où les articulations de l’arabité et du genre se matérialiseraient selon des relations d’équivalence et de différence. Elle fait l’objet d’une analyse critique de trois campagnes ayant eu cours sur l’UWAW en 2014. Ces dernières sont abordées comme des lieux de discours, soit des espaces construits dans et par un recours à des discours spécifiques qui participent à la production de savoirs situés dont ils sont aussi, de quelque manière, les produits. Ainsi, l’analyse s’attarde à comprendre comment la production de sens repose sur des discours concurrentiels qui puisent dans des savoirs différents qu’ils contribuent à faire circuler. L’analyse démontre la grande hétérogénéité de l’arabité qui s’est manifestée sous un visage distinct dans chaque campagne. Elle est homogénéisée et universalisée dans Do You know, clivée dans Israël Apartheid Week, et citoyenne dans « Je ne resterai pas silencieuse ». Le genre est davantage stabilisé, puisqu’il agit principalement comme force universalisante dans les trois campagnes.

Development of Best Practices for Ship Recycling Processes

Ship recycling has been considered as the best means to dispose off an obsolete ship. The current state of art of technology combined with the demands of sustainable developments from the global maritime industrial sector has modified the status of erstwhile ‘ship breaking’ involving ship scrap business to a modern industry undertaking dismantling of ships and recycling/reusing the dismantled products in a supply chain of pre owned product market by following the principles of recycling. Industries will have to formulate a set of best practices and blend them with the engineering activities for producing better quality products, improving the productivity and for achieving improved performances related to sustainable development. Improved performance by industries in a sustainable development perspective is accomplished only by implementing the 4E principles, ie.,. ecofriendliness, engineering efficiency, energy conservation and ergonomics in their core operations. The present study has done a comprehensive investigation into various ship recycling operations for formulating a set of best practices.Being the ultimate life cycle stage of a ship, ship recycling activities incorporate certain commercial procedures well in advance to facilitate the objectives of dismantling and recycling/reusing of various parts of the vessel. Thorough knowledge regarding these background procedures in ship recycling is essential for examining and understanding the industrial business operations associated with it. As a first step, the practices followed in merchant shipping operations regarding the decision on decommissioning have been and made available in the thesis. Brief description about the positioning methods and important preparations for the most feasible ship recycling method ie.,. beach method have been provided as a part of the outline of the background information. Available sources of guidelines, codes and rules & regulations for ship recycling have been compiled and included in the discussion.Very brief summary of practices in major ship recycling destinations has been prepared and listed for providing an overview of the global ship recycling activities. The present status of ship recycling by treating it as a full fledged engineering industry has been brought out to establish the need for looking into the development of the best practices. Major engineering attributes of ship as a unique engineering product and the significant influencing factors on her life cycle stage operations have been studied and added to the information base on ship recycling. Role of ship recycling industry as an important player in global sustainable development efforts has been reviewed by analysing the benefits of ship recycling. A brief synopsis on the state of art of ship recycling in major international ship recycling centres has also been incorporated in the backdrop knowledgebase generation on ship recycling processes.Publications available in this field have been reviewed and classified into five subject categories viz., Infrastructure for recycling yards and methods of dismantling, Rules regarding ship recycling activities, Environmental and safety aspects of ship recycling, Role of naval architects and ship classification societies, Application of information technology and Demand forecasting. The inference from the literature survey have been summarised and recorded. Noticeable observations in the inference include need of creation of a comprehensive knowledgebase on ship recycling and its effective implementation in the industry and the insignificant involvement of naval architects and shipbuilding engineers in ship recycling industry. These two important inferences and the message conveyed by them have been addressed with due importance in the subsequent part of the present study.As a part of the study the importance of demand forecasting in ship recycling has been introduced and presented. A sample input for ship recycling data for implementation of computer based methods of demand forecasting has been presented in this section of the thesis.The interdisciplinary nature of engineering processes involved in ship recycling has been identified as one of the important features of this industry. The present study has identified more than a dozen major stake holders in ship recycling having their own interests and roles. It has also been observed that most of the ship recycling activities is carried out in South East Asian countries where the beach based ship recycling is done in yards without proper infrastructure support. A model of beach based ship recycling has been developed and the roles, responsibilities and the mutual interactions of the elements of the system have been documented as a part of the study Subsequently the need of a generation of a wide knowledgebase on ship recycling activities as pointed out by the literature survey has been addressed. The information base and source of expertise required to build a broad knowledgebase on ship recycling operations have been identified and tabulated. Eleven important ship recycling processes have been identified and a brief sketch of steps involved in these processes have been examined and addressed in detail. Based on these findings, a detailed sequential disassembly process plan of ship recycling has been prepared and charted. After having established the need of best practices in ship recycling initially, the present study here identifies development of a user friendly expert system for ship recycling process as one of the constituents of the proposed best practises. A user friendly expert system has been developed for beach based ship recycling processes and is named as Ship Recycling Recommender (SRR). Two important functions of SRR, first one for the ‘Administrators’, the stake holders at the helm of the ship recycling affairs and second one for the ‘Users’, the stake holders who execute the actual dismantling have been presented by highlighting the steps involved in the execution of the software. The important output generated, ie.,. recommended practices for ship dismantling processes and safe handling information on materials present onboard have been presented with the help of ship recycling reports generated by the expert system. A brief account of necessity of having a ship recycling work content estimation as part of the best practices has been presented in the study. This is supported by a detailed work estimation schedule for the same as one of the appendices.As mentioned earlier, a definite lack of involvement of naval architect has been observed in development of methodologies for improving the status of ship recycling industry. Present study has put forward a holistic approach to review the status of ship recycling not simply as end of life activity of all ‘time expired’ vessels, but as a focal point of integrating all life cycle activities. A new engineering design philosophy targeting sustainable development of marine industrial domain, named design for ship recycling has been identified, formulated and presented. A new model of ship life cycle has been proposed by adding few stages to the traditional life cycle after analysing their critical role in accomplishing clean and safe end of life and partial dismantling of ships. Two applications of design for ship recycling viz, recyclability of ships and her products and allotment of Green Safety Index for ships have been presented as a part of implementation of the philosophy in actual practice.

Double burden malnutrition of preschool children and its association with brain development and milk consumption

Protecting the quality of children growth and development becomes a supreme qualification for the betterment of a nation. Double burden child malnutrition is emerging worldwide which might have a strong influence to the quality of child brain development and could not be paid-off on later life. Milk places a notable portion during the infancy and childhood. Thus, the deep insight on milk consumption pattern might explain the phenomenon of double burden child malnutrition correlated to the cognitive impairments. Objective: Current study is intended (1) to examine the current face of Indonesian double burden child malnutrition: a case study in Bogor, West Java, Indonesia, (2) to investigate the association of this phenomenon with child brain development, and (3) to examine the contribution of socioeconomic status and milk consumption on this phenomenon so that able to formulate some possible solutions to encounter this problem. Design: A cross-sectional study using a structured coded questionnaire was conducted among 387 children age 5-6 years old and their parents from 8 areas in Bogor, West-Java, Indonesia on November 2012 to December 2013, to record some socioeconomic status, anthropometric measurements, and history of breast feeding. Diet and probability of milk intake was assessed by two 24 h dietary recalls and food frequency questionnaire (FFQ). Usual daily milk intake was calculated using Multiple Source Method (MSM). Some brain development indicators (IQ, EQ, learning, and memory ability) using Projective Multi-phase Orientation method was also executed to learn the correlation between double burden child malnutrition and some brain development indicator. Results and conclusions: A small picture of child double burden malnutrition is shown in Bogor, West Java, Indonesia, where prevalence of Severe Acute Malnutrition (SAM) is 27.1%, Moderate Acute Malnutrition (MAM) is 24.9%, and overnutrition is 7.7%. This phenomenon proves to impair the child brain development. The malnourished children, both under- and over- nourished children have significantly (P-value<0.05) lower memory ability compared to the normal children (memory score, N; SAM = 45.2, 60; MAM = 48.5, 61; overweight = 48.4, 43; obesity = 47.9, 60; normal = 52.4, 163). The plausible reasons behind these evidences are the lack of nutrient intake during the sprout growth period on undernourished children or increasing adiposity on overnourished children might influence the growth of hippocampus area which responsible to the memory ability. Either undernutrition or overnutrition, the preventive action on this problem is preferable to avoid ongoing cognitive performance loss of the next generation. Some possible solutions for this phenomenon are promoting breast feeding initiation and exclusive breast feeding practices for infants, supporting the consumption of a normal portion of milk (250 to 500 ml per day) for children, and breaking the chain of poverty by socioeconomic improvement. And, the national food security becomes the fundamental point for the betterment of the next. In the global context, the causes of under- and over- nutrition have to be opposed through integrated and systemic approaches for a better quality of the next generation of human beings.

Synthesis of antimicrobial peptides derived from BP100 and BPC194

In the present PhD thesis we studied the solid-phase peptide synthesis of antimicrobial peptides derived from the lead peptides BP100 and BPC194. First, peptides derived from BP100 containing D-amino acids at different positions of the sequences were prepared. Moreover, peptidotriazoles derived from BP100 were also synthesized containing the triazole ring at the side-chain of different amino acids. Then, we proceeded to perform studies for the synthesis of multivalent peptides derived from BPC194. To achieve this objective, the synthesis of cyclic peptides containig a triazole ring at amino acids side-chain with different elongations was carried out. Finally, we prepared various carbopeptides containing 2 and 4 units of BP100 and/or its derivatives. The evaluation of the biological activity allowed the identification of active sequences against the economically important phytopathogenic bacteria and fungi and not toxic against eukaryotic cells.

Effects of priority and emerging pollutants on river biofilms

L'activitat humana representa una de les majors causes d'entrada d'una gran varietat de substàncies en els ecosistemes fluvials. L'objectiu principal d'aquest treball es investigar els efectes que els tòxics orgànics poden exercir en els biofilms fluvials. El riu Llobregat ha estat sotmès a fortes pressions, fet que l'ha portat a uns nivells molt elevats de contaminació. En aquest estudi s'ha observat una influència dels plaguicides presents al riu en la distribució de la comunitat de diatomees, així com efectes en el biofilm a nivell funcional i estructural. Experiments amb canals experimentals han mostrat que l'herbicida diuron i el bactericida triclosan poden ocasionar una cadena d'efectes en els biofilms, incloent efectes directes i també efectes indirectes en les relacions entre els components del biofilm. Experiments amb cultius algals han mostrat que aquests tòxics, aplicats en barreja, poden tenir una major toxicitat de la prevista pels models, resultant en efectes sinèrgics.

The role of eddies in driving the tropospheric response to stratospheric heating perturbations

A simplified general circulation model has been used to investigate the chain of causality whereby changes in tropospheric circulation and temperature are produced in response to stratospheric heating perturbations. Spinup ensemble experiments have been performed to examine the evolution of the tropospheric circulation in response to such perturbations. The primary aim of these experiments is to investigate the possible mechanisms whereby a tropospheric response to changing solar activity over the 11-yr solar cycle could be produced in response to heating of the equatorial lower stratosphere. This study therefore focuses on a stratospheric heating perturbation in which the heating is largest in the tropics. For comparison, experiments are also performed in which the stratosphere is heated uniformly at all latitudes and in which it is heated preferentially in the polar region. Thus, the mechanisms discussed have a wider relevance for the impact of stratospheric perturbations on the troposphere. The results demonstrate the importance of changing eddy momentum fluxes in driving the tropospheric response. This is confirmed by the lack of a similar response in a zonally symmetric model with fixed eddy forcing. Furthermore, it is apparent that feedback between the tropospheric eddy fluxes and tropospheric circulation changes is required to produce the full model response. The quasigeostrophic index of refraction is used to diagnose the cause of the changes in eddy behavior. It is demonstrated that the latitudinal extent of stratospheric heating is important in determining the direction of displacement of the tropospheric jet and storm track.

Complete filling of zeolite frameworks with polyalkynes formed in situ by transition-metal ion catalysts

We report the use of transition-metal-exchanged zeolites as media for the catalytic formation and encapsulation of both polyethyne and polypropyne, and computer modeling studies on the composites so formed. Alkyne gas was absorbed into the pores of zeolite Y (Faujasite) exchanged with transition-metal cations [Fe(II), Co(II), Cu(II), Ni(II), and Zn(II)]. Ni(II) and Zn(II) were found to be the most efficient for the production of poly-ynes. These cations were also found to be effective in polymer generation when exchanged in zeolites mordenite and beta. The resulting powdered samples were characterized by FTIR, Raman, diffuse reflectance electronic spectroscopy, TEM, and elemental analysis, revealing, nearly complete loading of the zeolite channels for the majority of the samples. Based on the experimental carbon content, we have derived the percentage of channel filling, and the proportion of the channels containing a single polymer chain for mordenite. Experimentally, the channels for Y are close to complete filling for polyethyne (PE) and polypropyne (PP), and this is also true for polyethyne in mordenite. Computer modeling studies using Cerius2 show that the channels of mordenite can only accept a single polymer chain of PP, in which case these channels are also completely filled.

Cascade dicopper architectures of a dibenzodioxatetraazamacrocycle

The dibenzodioxatetraazamacrocycle [26]pbz(2)N(4)O(2) was characterised by single crystal X-ray diffraction and the protonation constants of this compound and the stability constants of its copper(II) and lead(II) complexes were determined by potentiometry in water at 298.2 K in 0.10 mol dm(-3) in KNO3. Mono- and dinuclear complexes were found for both metal ions, the dinuclear complexes being the main species in the 5-7.5 pH range for copper(II) and 7.5-8.5 for lead(II). As expected the values of the stability constants for the copper(II) complexes are lower than those for related macrocycles containing only nitrogen atoms. The presence of mono- and dinuclear copper complexes was also confirmed by electrospray ionization mass spectrometry. These results suggest that the symmetric macrocyclic cavity of [26]pbZ(2)N(4)O(2) has enough space for the coordination of two metal ions. Additionally, NMR spectroscopy showed that the dinuclear complex of lead(II) has high symmetry. The equilibrium constants of the dinuclear copper(II) complexes and dicarboxylate anions (oxalate, malonate and succinate) were also determined in 0.10 mol dm-3 aqueous KNO3 solution. Only species containing one anion, Cu(2)H(h)LA((2+h)), were found, strongly suggesting that the anion bridges the two copper(II) ions. The binding constants of the cascade species formed by [Cu-2[26]pbZ(2)N(4)O(2)(H2O)(4+) with dicarboxylate anions decrease with the increase in length of the alkyl chain of the anion, a fact which was attributed to a higher conformational energy necessary for the rearrangement of the macrocycle to accommodate the larger anions bridging the two copper(II) centres. The variation of the magnetic susceptibility with temperature Of [Cu-2(H-2[26]pbz(2)N(4)O(2))(oxa)(3)]-4H(2)O and [Cu-2([26]pbz(2)N(4)O(2))(suc)Cl-2] were measured and the two complexes showed different behaviour.

The component polypeptide chains of bovine insulin nucleate or inhibit aggregation of the parent protein in a conformation-dependent manner

Amyloid fibrils are typically rigid, unbrariched structures with diameters of similar to 10 nm and lengths up to several micrometres, and are associated with more than 20 diseases including Alzheimer's disease and type II diabetes. Insulin is a small, predominantly alpha-helical protein consisting of 51 residues in two disulfide-linked polypeptide chains that readily assembles into amyloid fibrils under conditions of low PH and elevated temperature. We demonstrate here that both the A-chain and the B-chain of insulin are capable of forming amyloid fibrils in isolation under similar conditions, with fibrillar morphologies that differ from those composed of intact insulin. Both the A-chain and B-chain fibrils were found to be able to cross-seed the fibrillization of the parent protein, although these reactions were substantially less efficient than self-seeding with fibrils composed of full-length insulin. In both cases, the cross-seeded fibrils were morphologically distinct from the seeding, material, but shared common characteristics with typical insulin fibrils, including a very similar helical repeat. The broader distribution of heights of the cross-seeded fibrils compared to typical insulin fibrils, however, indicates that their underling protofilament hierarchy may be subtly different. In addition, and remarkably in view of this seeding behavior, the soluble forms of the A-chain and B-chain peptides were found to be capable of inhibiting insulin fibril formation. Studies using mass spectrometry suggest that this behavior might be attributable to complex formation between insulin and the A-chain and B-chain peptides. The finding that the same chemical form of a polypeptide chain in different physical states can either stimulate or inhibit the conversion of a protein into amyloid fibrils sheds new light on the mechanisms underlying fibril formation, fibril strain propagation and amyloid disease initiation and progression.

Syntheses and crystal structures of two new coordination polymers of Cd(II) using organic spacer and inorganic-bridging ligands

Two new cadmium (II) complexes [Cd(hmt)(dca)(2)] (n) (1) and [Cd-3(hmt)(2)(SeCN)(6)(H2O)(2)] (n) (2) (hmt=hexamethylenetetramine, dca=dicyanamide) have been synthesized and characterized by X-ray single-crystal analysis. The complex 1 is a 2D rectangular grid of octahedral cadmium (II) with CdN6 chromophore where cadmium centers are doubly bridged by dicyanamide and hmt along a-axis, which are interlinked by dicyanamide running along c-axis. Whereas, complex 2 is a 1D chain of octahedral cadmium (II) with a three-leg ladder topology running along a-axis. The Cd(II) centers are doubly bridged through SeCN (infinite rail) along a-axis and singly bridged by hmt (two-step rung) along c-axis, having cadmium centers with CdSe2N3O and CdSe2N4 chromophores. The adjacent chains through H-bonding between coordinated water and hmt, and (SeSe)-Se-... interaction are extended to 2D supramolecular architecture.

Cu-II acetate complexes involving N,N,O donor Schiff base ligands: Mono-atomic oxygen bridged dimers and alternating chains of the dimers and Cu-2(OAc)(4)

Two tridentate N,N,O donor Schiff bases, HL1 (4-(2-ethylamino-ethylimino)-pentan-2-one) and HL2 (3-(2-amino-propylimino)-1-phenyl-butan-1-one) on reaction with Cu-II acetate in presence of triethyl amine yielded two basal-apical, mono-atomic acetate oxygen-bridging dimeric copper(II) complexes, [Cu2L21(OAc)(2)] (1), [Cu2L22(OAc)(2)] (2). Whereas two other similar tridentate ligands HL3 (4-(2-amino-propylimino)-pentane-2-one) and HL3 (3-(2-amino-ethylimino)-1-phenyl-butan-1-one) under the same conditions produced a mixture of the corresponding dinners and a one-dimensional alternating chain of the dimer and copper acetate moiety, [Cu4L23(OAc)(6)](n) (3) and [Cu4L24(OAc)(6)](n) (4), formed by a very rare mu(3) bridging mode of the acetate ion. All four complexes (1-4) have been characterized by X-ray crystallography. The isotropic Hamiltonian, H = -JS(1)S(2) has been used to interpret the magnetic data. Magnetic measurements of 1 and 2 in the temperature range 2-300 K reveal a very weak antiferromagnetic coupling for both complexes U = -0.56 and -1.19 cm(-1) for 1 and 2, respectively).

New high technology product development: The case of light emitting diodes

New high technology products usher in novel possibilities to transform the design, production and use of buildings. The high technology companies which design, develop and introduce these new products by generating and applying novel scientific and technical knowledge are faced with significant market uncertainty, technological uncertainty and competitive volatility. These characteristics present unique innovation challenges compared to low- and medium technology companies. This paper reports on an ongoing Construction Knowledge Exchange funded project which is tracking, real time, the new product development process of a new family of light emitting diode (LEDs) technologies. LEDs offer significant functional and environmental performance improvements over incumbent tungsten and halogen lamps. Hitherto, the use of energy efficient, low maintenance LEDs has been constrained by technical limitations. Rapid improvements in basic science and technology mean that for the first time LEDs can provide realistic general and accent lighting solutions. Interim results will be presented on the complex, emergent new high technology product development processes which are being revealed by the integrated supply chain of a LED module manufacture, a luminaire (light fitting) manufacture and end user involved in the project.

Farm animal welfare, consumer willingness to pay, and trust: results of a cross-national survey

Higher animal welfare standards increase costs along the supply chain of certified animal-friendly products (AFP). Since the market outcome of certified AFP depends on consumer confidence toward supply chain operators complying with these standards, the role of trust in consumer willingness-to-pay (WTP) for AFP is paramount. Results from a contingent valuation survey administered in five European Union countries show that WTP estimates were sensitive to robust measures of consumer trust for certified AFP. Deriving the WTP effect of a single food category on total food expenditure is difficult for survey respondents; hence, a budget approach was employed to facilitate this process.
