Palaeoethnobotany (or the shorter term, archaeobotany) is the study of the "direct interrelationships between humans and plants for whatever purpose as manifested in the archaeological record."50 No matter what the time period or geographical area, plants played an important role in human culture. As primary data about the natural environment, landuse practices, diet, architecture, and trade in...

"Spoilt Baby into Angry Young Man". Her theme is that the way children are brought up today is so sloppy and spineless that the result is the Angry Young Man. To prove her thesis she has assembled a series of statements, carefully indexed, made by angry adults. This attitude towards the young is a stage we all go through as we get older; let us be thankful that like the young, we also grow out ...

Lateral luxation of the patella has been described in horses and ponies. Medial luxation has been reported only twice. Upward fixation of the patella is not true luxation. This report concerns two cases of lateral luxation of the patella related to hypoplasia of the lateral ridge of the trochlea of the femur.

Accurate measurements of the muon component in EAS are particularily important for determination of the primary CR spectrum and composition. Multiparameter analysis possibilities in KASCADE have been recently enhanced by starting the operation of a large area streamer tube muon tracking detector. With its acceptance of about 500 m·sr it identifies EAS muons with energy exceeding 0.8 GeV. The re...

Model calculations are performed of extensive air shower (EAS) component energies using a variety of hadronic interaction parameters. A conversion factor from electromagnetic component energy to the energy of ultra-high energy cosmic rays (UHECRs) and its model and primary mass dependence is studied. It is shown that model dependence of the factor minimizes under the necessary condition of the ...

We propose an alternative mechanism for intracellular cargo transport which results from motor-induced longitudinal fluctuations of cytoskeletal microtubules (MTs). The longitudinal fluctuations combined with transient cargo binding to the MTs lead to long-range transport even for cargos and vesicles having no molecular motors on them. The proposed transport mechanism, which we call “hitchhikin...

The adult pattern of the azygos vein system of various mammals has received the attention of many early investigators (Eustachius, 1561 ; Bardeleben, 1848 ; Marshall, 1850; and Morrison, 1879). Since there has not almways been agreement among these workers in the patterns described, attempts were made by some of them to try to correlate the patterns on a developmental basis (Barcleleben, 1848 ;...

This project involves the production of a computer-based multimedia package for teaching Ecology at undergraduate level. The product will be designed to enhance the development of investigation skills in students of ecology and biology. It is a cross-faculty initiative involving collaboration between the Faculty of Education and the Department of Biological Sciences. The package will take full ...

This paper develops a theoretical model to help answer the following question— what influences an individual’s opinions regarding the right to privacy of others (individuals, organizations, and governments)? This question is particularly relevant for organizations and governments, for whom insider threats to corporate or government privacy present a dangerous risk. We draw from three bases of l...

Automatically generating text to accompany information graphics Mary Ellen Foster Master of Science Graduate Department of Computer Science University of Toronto 1999 Generally, when quantitative information is to be presented, some form of graphical presentation is used, often with a textual caption to ensure that the audience notices particular aspects of the data. This thesis presents the pr...
