The pathology, diagnosis and management of acute appendicitis. The essentials for that surgical FY1 placement!
Anthropological ideas
Anthropological Ideas introduces the key ideas and perspectives that will enable students to complete their introduction to anthropology. The course aims to give students an introductory understanding of the concepts, ideas and modes of thinking that have contributed to the development of modern social anthropology.

TALAT Lecture 2203: Structural materials fabrication
This lecture gives a brief introduction into the basic fabrication methods for structural aluminium alloy materials with respect to machining, forming, joining and surface treatments as a necessary background for the design process; it describes the subject of welding structural aluminium alloys in order to understand the materials requirements which the designer has to take into account when designing load carrying welded aluminium structures. General materials engineering background is assumed
Kevlar fibre composite shear surface
This is an image of the shear surface in a failed composite beam. 'Hackles' of matrix are clearly visible where shear has occurred within the matrix and it is also clear that shear has occurred across the fibre/matrix interface. The fibres are for the most part totally unscathed, though some mis-aligned fibres have become caught between the shear surfaces and 'fibrillated' by rolling and bending actions. It may be that this failure mechanism has been partly inhibited by poor fibre alignment sinc
Carbon-carbon composite
Carbon-carbon composites are manufactured from continuous carbon fibres which are woven in a two or three dimensional pattern. The fibres are then impregnated with a polymeric resin. After the component has been shaped and cured the matrix is pyrolysed by heating in an inert atmosphere. This converts the matrix to carbon chain molecules which are densified by further heat treatments. The resulting composite consists of the original carbon fibres in a carbon matrix. Carbon-carbon composites have

Kevlar fibre composite fracture surface
Because a relatively short beam was used, significant shear stresses existed in the beam, and failure has occurred principally by shear. In this mode, the specimen splits longitudinally along planes parallel to its neutral axis, due to shear failure within the matrix and at the weak interface between fibres and matrix. Matrix porosity (and particularly the long longitudinal voids present in this specimen), the poor wetting of fibres by the resin, and poor fibre distribution will all promote fail
Section of a metal matrix composite (MMC) after extrusion and annealing
Commercial purity aluminium has atomised, mixed with 13 micron spherical alumina particles, ball milled, tumbled, cold compacted (20MPa) and then extruded (with the working direction vertical in the image). It has then been annealed at 630 degrees C. Vertical stringers of fine oxide particles are visible. Note the small yellow 'island' grain which has formed within one of the recrystallised grains and is likely to have nucleated on the adjacent reinforcement particle. Note also the boundary face

Rock Deformation & Geological Structures
This Xerte resource is a translation of the original UKESCC courseware resource covering the deformation of rocks. It deals with the following sub-topics: Introduction to rock deformation; The analysis of stress; Deformation and finite strain; Brittle deformation; Ductile deformation. Each topic is covered theoretically and with natural examples.
Tensile failure surface of a carbon fibre composite
This is from the region of the fracture surface which was in tension. The fibres show clean, brittle fracture surfaces (with no fibrillation or distortion and little distortion of the matrix) and have broken at varying lengths and hence some stick out while others have left holes in the matrix. This is indicative of fibre pull-out having occurred after an initial failure of the matrix, followed by failure of the fibres themselves. This is a toughening mechanism in fibre reinforced composites. It

Techniques in Karyology: The Bone Marrow Extraction Method
This 2-hour laboratory exercise isolates chromosomes from bone marrow. After the chromosomes are isolated, they are stained and chromosomal spreads are examined microscopically to establish diploid number and chromosome morphology. This technique is applicable to all small mammals.
