Basic function in the nervous system - a unified theoryActa Biotheoretica - Tập 31 - Trang 185-202 - 1982
John Dempsher
A new theory for basic function in the nervous system has recently been proposed (Dempsher, J., 1979a, 1979b; 1980, 1981). The major basic themes of the new theory are as follows: (1) There are two fundamental units of structure and function, the fibre or conducting mechanism, and the neurocentre, where nervous system function as we know it takes place. (2) The nerve impulse is regarded as a mathe...... hiện toàn bộ
Quantifying Efficacy of Chemotherapy of Brain Tumors with Homogeneous and Heterogeneous Drug DeliveryActa Biotheoretica - Tập 50 - Trang 223-237 - 2002
Kristin R. Swanson, Ellsworth C. Alvord, J. D. Murray
Gliomas are diffuse and invasive brain tumors with the nefarious ability to evade even seemingly draconian treatment measures. Here we introduce a simple mathematical model for drug delivery of chemotherapeutic agents to treat such a tumor. The model predicts that heterogeneity in drug delivery related to variability in vascular density throughout the brain results in an apparent tumor reduction b...... hiện toàn bộ
Again, What the Philosophy of Biology is notActa Biotheoretica - Tập 53 - Trang 93-122 - 2005
Werner Callebaut
There are many things that philosophy of biology might be. But, given the existence of a professional philosophy of biology that is arguably a progressive research program and, as such, unrivaled, it makes sense to define philosophy of biology more narrowly than the totality of intersecting concerns biologists and philosophers (let alone other scholars) might have. The reasons for the success of t...... hiện toàn bộ
Modelling the Influence of Climatic Factors on the Population Dynamics of Radopholus Similis: Banana-Plantain PestActa Biotheoretica - Tập 70 - Trang 1-26 - 2022
S. Fotso, G. Kolaye, J. Ntahomvukiye, S. Bowong, V. Taffouo
Radopholus Similis (R. Similis) or burrowing nematode, is one of the most damaging and widespread nematodes attacking bananas, causing toppling or blackhead disease. A mathematical model for the population dynamics of R. Similis is considered, with the aim of investigating the impact of climatic factors on the growth of R. Similis. In this paper, based on the life cycle of R. Similis, we first pro...... hiện toàn bộ
Competitive exclusion, coexistence and community structureActa Biotheoretica - Tập 37 - Trang 281-313 - 1988
G. H. Walter
Studies of coexistence are based ultimately on the assumption that competitive exclusion is a general and accredited phenomenon in nature. However, the ecological and evolutionary impact of interspecific competition is of questionable significance. Review of three reputed examples of competitive exclusion in the field (Aphytis wasps, red and grey squirrels, and triclads) demonstrates that the wide...... hiện toàn bộ
