Résumé :

Developing the connection between biology and mathematics is one of the most important ways to shift the paradigms of both established science disciplines. However, adding some mathematic content to biology or biology content to mathematics is not enough but must be accompanied by development of suitable pedagogical models. I propose a model of pedagogical mathematical biological content knowledge as a feasible starting point for connecting biology and mathematics in schools and universities. The process of connecting these disciplines should start as early as possible in the educational proce

Résumé :

In general biologists are not accustomed to formulating biological problems in the precise mathematical terms that are required to solve the problems analytically or numerically. Although many computational tools for systems biology have been developed recently, our observations indicate that many of these tools are powerful only in the hands of those who know a lot about how to use them. For most biologists, the tools have a protracted learning curve and unfriendly user interface that often diminish their likelihood of being used. Our long-term goal is to build a knowledge system that allows

The steady state (s.s.) is а very important notion for understanding of nature and functional mechanisms оп various biclogical systems. Physiological homoeostasis is one of the notions connected with mathematic notion of the s.s. The character of organisms functional changes under variation of environmental conditions depends on the number оf s.s. and types of stability, which are programmed by the system’s structure. At complex nonlinear dynamic system as а result of the system’s nonstability the regimes known as «trigger», «oscillator» and «chaos» may arise. A set of mathematical models is a

Résumé :

Bellis perennis is an interesting daisy not for its ornamental usage but also for its bioactive compounds, particularly phenolics, and related biological effects that explain traditional application for many disorders. The objective of this study was the optimization of phenolic compounds extraction from B. perennis flower with microwave-assisted extraction (MAE) using response surface methodology (RSM) and assessing optimal extract for bioactive contents and in vitro biological properties. The optimization of phenolic extraction was performed by studying four parameters (solvent concentration

Résumé :

Reliable quantification in biological systems of endogenous low- and high-molecular substances, drugs and their metabolites, is of particular importance in diagnosis and therapy, and in basic and clinical research. The analytical characteristics of analytical approaches have many differences, including in core features such as accuracy, precision, specificity, and limits of detection (LOD) and quantitation (LOQ). Several different mathematic approaches were developed and used for the comparison of two analytical methods applied to the same chemical compound in the same biological sample. Gener

The objective of the paper is to present one method that solves the problem of election of a suitable export strategy using method of multi criteria evaluation. The initial hypothesis assumes limited financial and personal resources of a company generating necessity of incremental penetration to export markets with dependence on budget and expected results. The method also assumes individual choice of a single export strategy for each market. Number of formulated export strategies equals to the number of penetrated markets. The process of formulation of a new strategy consists of two steps. In

Résumé :

The students who study biology often develop fear from mathematical concepts and tend to avoid the pages of biology textbook where mathematical details are included. The students often perceive Mathematics and Biology as two separate disciplines of study. One of the main reasons for this perception is that biology textbooks do not include relevant mathematical details in biological concepts. Moreover, biology teachers often have little or no mathematical academic background while mathematics is taught by teachers with least or no interest in biology. This often leads to the lack of understandi

This article explains how mathematical modeling is used in neural networks with much focus on artificial neural networks or ANN and the biological neural system. It offers an introduction to the objects defining the type of model – architecture of neural networks, the mathematical models of neuron behavior – and learning algorithms used for training. The article consolidates the progress and issues surrounding the enhancement of neural network usability toward more biological realism about artificial models and their biological counterparts. It further goes to the new methodologies, including

Developed models allow taking into account the influence of such factors as geometric, physical and chemical parameters of the neuron's filaments and the presence of different neurotransmitters in chemical synapses on transmitting a neural impulse. Further, such models can be used for investiga

The value of the albedo of snow and ice surface is associated with the texture and structure of the surface layer of snow or ice (sea ice, glaciers), the peculiarities of the vertical redistribution of contaminations in this layer (mineral or organic particles of various concentrations, the size and shape), temperature regime of the surface layer of the atmosphere. Identifying links with the albedo characteristics of natural and artificial contamination is very important.

The multifunctional scavenger receptor stabilin-1 (STAB1, FEEL-1, CLEVER-1, KIAA0246) is expressed on tissue macrophages and sinusoidal endothelial cells in healthy organisms, and its expression on both macrophages and different subtypes of endothelial cells is induced during chronic inflammation and tumor progression. Stabilin-1 is a type-1 transmembrane receptor that mediates endocytic and phagocytic clearance of “unwanted-self” components, intracellular sorting of the endogenously synthesized chitinase-like protein SI-CLP, and transcytosis of the growth hormone family member placental lacto

Some children experience severe struggles in understanding mathematical concepts. A condition called ‘dyscalculia’ impairs learners’ capacity and limits their ability to perform and comprehend a mathematical concept. This study identifies factors that contribute to the weak academic performance by learners in mathematics. An empirical approach was used to gather data from a mainstream school and a special school. Interviews were conducted with teachers, occupational therapists, and learners. Virtual interviews included doctors and educational psychologists. The study revealed that learners' ab

AbstractThe principles of sexual selection were used as an organizing framework for interpreting cross-national patterns of sex differences in mathematical abilities. Cross-national studies suggest that there are no sex differences in biologically primary mathematical abilities, that is, for those mathematical abilities that are found in all cultures as well as in nonhuman primates, and show moderate heritability estimates. Sex differences in several biologically secondary mathematical domains (i.e., those that emerge primarily in school) are found throughout the industrialized world. In parti
