Direct design of reinforced concrete skew slabs / Laila Mahmoud Abd El Hafez 

Public ISBD Titre : Direct design of reinforced concrete skew slabs Type de document : texte imprimé Auteurs : Laila Mahmoud Abd El Hafez, Auteur ; Bhatt, P., Directeur de thèse Editeur : Glasgow : University of Glasgow Année de publication : 1986 Importance : 413 f. Présentation : ill. Format : 27 cm. Note générale : Thèse d'Etat: Génie Civil : West Yorkshire, University of Glasgow : 1986 Annexe f. 414 - 420 . Bibliogr. f. 421 - 435 Langues : Anglais (eng) Mots-clés : Reinforced  concrete  slabs  ;  Nonlinear  analysis  ;  Finite  element  method Index. décimale : D000386 Résumé : This thesis presents the results of an experimental and theoretical study of reinforced concrete skew slabs designed using the elastic stress fields in conjunction with the yield criterion for reinforced concrete slabs. The elastic stress field is obtained from finite element program using uncracked stiffness and the yield criterion adopted is given by (M*x - Mx + M* cos²α)(M* sin²α - My) - (Mxy + M*α sinα cosα)² = 0 where Mx, My and Mxy are the elastic applied bending and torsion moments normal to the x and y axis at the ultimate load. M*x and M*α are the ultimate flexural moment capacities of the section normal to the x and skew axis respectively and α is the angle of skew between x and α axis. The experimental work was conducted on a "large scale" skew slabs. The models included slabs of uniform thickness and ribbed slabs. The major parameters were the angle of skew and the arrangement of steel in the slab viz orthogonal or skew directions. The theoretical work was done using the nonlinear finite element program based on the isoparametric Mindlin element. In order to allow for the development of cracks through the thickness, the "layer approach" was adopted. Nonlinear effects due to the yielding of steel, cracking and crushing of concrete were included. A nonlinear finite element program was used to study the spread of yielded zones in the slab, the effect of fixing the direction of crack at its first appearance, prediction of the true deflection at working loads from the elastic deflection at working loads and a careful study of the yield criterion itself. The results show that the design procedure adopted is viable but care has to be taken to ensure that punching shear failure does not occur at obtuse corners.

Iron-uptake systems and transport in staphylococcus aureus / Ahmed Bensoltane 

Public ISBD Titre : Iron-uptake systems and transport in staphylococcus aureus Type de document : texte imprimé Auteurs : Ahmed Bensoltane, Auteur Editeur : Glasgow : University of Glasgow Année de publication : 1992 Importance : 143 f. Présentation : ill. Format : 27 cm. Note générale : Thèse de Doctorat : Microbiologie : Royaume-Uni, University of Glasgow : 1992 Bibliogr. f. 144 - 171 Annexe f. 172 - 179 Langues : Anglais (eng) Mots-clés : Iron-uptake  systems Staphylococci  isolated S.  aureus  strains Iron-chelators Thin  layer  chromatography Staphylococcus  aureus Index. décimale : D001392 Résumé : The main objective of this thesis was the characterisation of iron-uptake systems in staphylococci isolated from different sources and investigation of the possible role of these in pathogensis. The iron-uptake systems of S. aureus strains were investigated by growing the cells in the presence of different iron-chelators. With the synthetic iron-chelators, α,α-dipyridyl and EDDA, siderophores were produced which could not be detected by the Arnow assay for phenolates or the Csaky test for hydroxamates. They were detected by paper chromatography, by thin layer chromatography (TLC) and with the Chrome Azurol S (CAS, blue agar) plates of Schwyn and Neilands. The siderophore of S. aureus C336 was partially purified by solvent extraction, column chromatography and TLC and partially characterised as a phenolate. In the presence of the natural chelator, transferrin, staphylococci grew well but produced no detectable siderophore. As the rate of uptake of ⁵⁵Fe by staphylicocci was faster in the presence of transferrin than EDDA it appeared that staphylococci interacted directly with transferrin to obtain iron. Transferrin was radiolabelled with ¹²⁵-I and in competitive binding exoeriments to cells was indistinguishable from native transferrin. Radiolabelled transferrin bound rapidly to staphylococci, reaching saturation after approximately 20 minutes when approximately 350 and 206 molecules per cell were bound by S. aureus strains C336 and GRI-15586 respectively. The binding affinity of transferrin for staphylococci was low (8 x 10⁶ litres/mole) and cells were estimated to possess approximately 20000 binding sires for transferrin. In contrast to the pathogenic isolates of staphylococci, commensal strains of S. aureus from humans grew in the presence of EDDA but no siderophores were detectable with the CAS blue agar plates or the Arnow or Csaky assays. Addition of KCN to growing cultures of the commensals did not inhibit their growth, in contrast to the pathogenic isolates. It is concluded that staphylococci exhibit at least 3 responses to iron-restriction. They may interact directly with transferrin, produce siderophores or, in the case of commensals, grow without utilisation of iron. Pathogenic staphylococci may use the siderophore-mediated uptake system to provide iron in locations where transferrin is absent or present only in low concentration.

A nonlinear finite element study of reinforced concrete beams / Akthem Abdulkarim Al Manaseer 

Public ISBD Titre : A nonlinear finite element study of reinforced concrete beams Type de document : texte imprimé Auteurs : Akthem Abdulkarim Al Manaseer, Auteur ; D. V. Phillips, Directeur de thèse Editeur : Glasgow : University of Glasgow Année de publication : 1983 Importance : 410 f. Présentation : ill. Format : 27 cm. Note générale : Thèse de Doctorat : Génie Civil : Royaume-Uni, University of Glasgow : 1983 Bibliogr. [28] f. Annexe [16] f Langues : Anglais (eng) Mots-clés : Nonlinear  --  finite  element  method Reinforced  --  concrete  beams Smeared  --  crack  approach Endochronic  --  theory Isoparametric  --  elements Modified  --  newton-raphson  approach Tension  --  stiffening  effects Index. décimale : D003383 Résumé : This thesis describes the development of plane stress, nonlinear finite element method of analysis for reinforced concrete beams. These include simple, deep, and T-beams, failing in flexure and in shear. The nonlinear response is assumed to be caused by concrete cracking, nonlinear biaxial stress-strain relations, and by the yielding of steel reinforcement. The smeared crack approach was used with two models for post cracking behaviour, one with a tension stiffening effect and the other with no-tension stiffening. The endochronic theory with some adaptations was used to account for all other uncracked zones. 8-noded isoparametric elements were used for concrete representation and 3-noded isoparametric elements for steel. A modified Newton-Raphson approach, was used for solving the nonlinear problem with both the constant and variable stiffness methods. This was based on the evaluation of a tangential elasticity matrix. The unbalanced nodal forces were obtained by the method of residual forces and convergence was checked using either a force or a displacement criteria. A nonlinear finite element program was developed where all, the required aspects to model the reinforced concrete structures were included. It was a main contention of this work that the nonlinear solution parameters had such an important influence on the solution process that an extensive study was required to determine their effects. This was carried out on simple and complex beams, and suitable guide lines were established. In particular tension stiffening effects were investigated and rejected in favour of a method with no-tension stiffening used in conjunction with controls on other solution parameters. Other parameters such as order of Gauss rule, shear retention factor, convergence tolerance, etc. were also studied in detail. An investigation into the behaviour of a range of deep beams including perforated deep beams and beams which were heavily reinforced, was undertaken. These beams failed both in shear and flexure. In most cases crack pattern, stress distribution, and load deflection curves were used to validate, (or otherwise), the performance of the proposed models and program. Finally a method is proposed for analysing T-beams using plane stress elements where the flange is treated separately and is connected to the web by a fictitious element. Other approximations are introduced in order to treat the problem as a two dimensional structure.

Quinone methides related to 1-naphthol / Nourreddine Beghidja 

Public ISBD Titre : Quinone methides related to 1-naphthol Type de document : texte imprimé Auteurs : Nourreddine Beghidja, Auteur ; J. Carnduff, Directeur de thèse Editeur : Glasgow : University of Glasgow Année de publication : 1986 Importance : 113 f. Présentation : ill. Format : 27 cm. Note générale : Mémoire de Master : Génie Chimique : Ecosse, University of Glasgow : 1986 Bibliogr. f. 114 - 118 Langues : Anglais (eng) Mots-clés : 1-naphthol Quinone  methides Carbon  disulphide Dibromoethane Paraisomer Dihydrophenol 2-Methyl-naphthoquinonemethide Index. décimale : Ms00286 Résumé : This thesis contains three short reviews as follows: 1/ Reaction of 1-naphthol with electrophiles 2/ Formylation of 1-naphthol 3/ Preparation methods and different types of reactionsof quinone methides. Repetition of treatment of 1-naphthol with carbon disulphide and then dibromoethane gives the two isomeric quinonemethides (A) and (B) and not, as claimed earlier, exclusively the para isomer. The major product of this reaction is proved to be the ortho one by detailed analysis of its spectra and by reduction via a dihydroderivative to 2-methyl-1-naphthol which was prepared independently for comparaison. The para isomer is present in very small amount but it can be isolated by chromatography and its structure confirmed spectroscopically. This thesis describes an investigation of a specific route to the para isomer. Several methods to formylate 1-naphthol were investigated. The Gattermann Adams reaction proved most effective. The dihydrophenol (c) was made from 4-formyl-1-naphthol but attempts using a wide range of oxidising agents failed to convert it to (A). The 2-bromoderivative also failed undergo clean oxidation. 2-Methyl-naphthoquinonemethide (D) was prepared by the CS₂ reaction and characterised, but 2-chloro- and 2-bromonaphthols failed to give the corresponding quinone methide. Changing the solvent of the original reaction of 1-naphthol gave the two isomers in the ratio (1:1). The two isomers were successfully isolated and fully characterised and their spectra is reported. The nmr spectra of (A) were found to be affected by the presence of acid. Quinone methides related to 1-naphthol [texte imprimé] / Nourreddine Beghidja, Auteur ; J.

A sulphur isotope study of the Caledonian granites of Britain and Ireland / Rabah Laouar 

Public ISBD Titre : A sulphur isotope study of the Caledonian granites of Britain and Ireland Type de document : texte imprimé Auteurs : Rabah Laouar, Auteur ; Bernard E. Leake, Directeur de thèse ; Colin Farrow, Directeur de thèse Editeur : Glasgow : University of Glasgow Année de publication : 1987 Importance : 130 f. Présentation : ill. Format : 27 cm. Note générale : Mémoire de Master : Génie Minier : Ecosse, University of Glasgow : 1987 Bibliogr. f. 131 - 144 Langues : Anglais (eng) Mots-clés : Caledonian  granites S-type  granites I-type  granites Sulphur  isotopes Dalradian Index. décimale : Ms00187 Résumé : The Caledonian fold belt is thought to have formed as a result of the closure of the 'Iapetus' ocean basin during Lower Palaeozoic times. Granitic magmas were intruded into Precambrian and Lower Palaeozoic country rocks between approximately 640 and 390 Ma. Most important, spatially and volumetrically, are the late Caledonian granites, the 'Newer' and 'Last' granites of Read. In general, the late Caledonian granites have the calc-alkaline characteristics typical of plutonic rocks emplaced at destructive plate margins. They range in composition from diorite and tonalite, through granodiorute, to peraluminous granite with chemical variation continuous among the various rock types. Petrographically and chemically, the granitoids span the range from S 'sedimentary' to I 'igneous' types as defined by Chappell and White, with no discernible geographical pattern to their distribution. There have been few sulphur isotope studies on primary sulphides in granites; yet such data have considerable potential in understanding the petrogenesis; that is in terms of granites derived either from igneous or metasedimentary protoliths. From about 50 British and Irish Caledonide granites, including both 'Newer' and 'Older' intrustions, conventional separation techniques have yielded sulphide separates from only 19 granites for analyses. Mineralogical, the sulphides consist of maily pyrite and pyrrhotite, although chalcopyrite is present in a few intrusions. It was noticeable that granites with high δ¹⁸0 and high initial ⁸⁷Sr/⁸⁶Sr yielded very little sulphides. Sulphur isotope analyses of coexisting sulphide minerals are also useful as a geothermometer as long as the sulphide-bearing phases are in equilibrium. The putative temperature of formation of two coexisting mineral pairs from the Oughterard granite has been calculated; 418°C from a pyrite-pyrrhotite pair and 441°C from a pyrite-chalcopyrite pair. The results of sulphur isotope analyses coupled with the above geochemical and isotopic parameters have proved useful in understanding granite genesis, and hence distinguishing the Caledonian intrusions in terms of precursor protolith.
