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
Electrochemical Potentials and Pressures of Biofluids from Common Experimental DataActa Biotheoretica - Tập 51 - Trang 173-180 - 2003
E. Mamontov, M. Willander
Many biosystems are complex mixtures of disparate biofluids. To study contact and transport phenomena in these mixtures, one has to apply much information on the biofluids which are components of the mixtures. A lot of the corresponding data can be extracted by means of experiments. However, it is not always easy to obtain experimental results on rather deep physical characteristics of biofluids, ...... hiện toàn bộ
A Theoretical Approach on Controlling Agricultural Pest by Biological ControlsActa Biotheoretica - Tập 62 - Trang 47-67 - 2013
Prasanta Kumar Mondal, Soovoojeet Jana, T. K. Kar
In this paper we propose and analyze a prey-predator type dynamical system for pest control where prey population is treated as the pest. We consider two classes for the pest namely susceptible pest and infected pest and the predator population is the natural enemy of the pest. We also consider average delay for both the predation rate i.e. predation to the susceptible pest and infected pest. Con...... hiện toàn bộ
