Such an animal may have a life span of about 40 years.
Based on the understanding of how common diseases, such as cardiovascular disease, develop over a life span, it is likely more correct to assume that prevention postpones disease events rather than entirely avoids them.
Then there exists a life span T > 0 such that problem (1.1) has a weak solution u ( x, t ) ∈ L 2 ( [ 0, T ], H s ( R ) ) in the sense of a distribution and u x ∈ L ∞ ( [ 0, T ] × R ).
Some students, such as student 4, described traits as if they had a life span.
"They have a life span," he said.
"This is especially important for a game with such a long life span".
To a large extent, mouse models of retinal disease recapitulate the human disease, albeit at a different time course and with limitations that stem from the differences between the two species, such as life span and absence of a cone-rich macular region in mice.
In addition, the Drosophila model system offers other advantages such as a short life span, a large progeny size and the availability of genetic markers and tools.
If the procedures, described above, do select longevity variants, and if the detected pattern of joint influence of such variants on life span is a property of a biological mechanism, then genetic variants selected using data on one population should be able to predict life spans in other genetically independent population of individuals who experienced similar environmental and living conditions.
To what extent do changes to key parameters such as life span influence the results?
