A MATHEMATICAL MODEL FOR STIMULATED HYPOTHALAMICPITUITARY ADRENAL REACTIVITY DYNAMIC CHANGES IN HEALTHY PATIENTS

A mathematical model for calculating contact mass loss resulting from bridge disintegration in vacuum The paper presents descriptions of bridge disintegration types and contact mass loss in the bridge stage. There is presented Matlab solvers to solve equation describing dynamic changes of temperature in the bridge region. The final result of program calculations is the mass loss and the volume of the metal of contacts which was lost during the bridge stage.

Property Registration

The article is about identification of statistical patterns in the field of trademarks and service marksregistration. To identify patterns, official statistical data provided in the relevant state collections were used. The analysis of dynamic changes in the certificates and the filled applications allowed us to indicate positive conclusions about the intellectual property registration in Russia. The article also provided the hypothesis of the dependency between the number of organizations in a certain region and the number of registered trademarks and service marks. It was concluded that the hypothesis put forward about the presence of a possible dependence between the number of organizations in a certain region and the number of registered trademarks and service marks was partially confirmed. There really is a pattern, that is, with an increase in the number of organizations in a certain region, the number of registered trademarks and service marks increased, but it was not possible to build a clear mathematical model of dependence.

Adrenal Cortical Cells

Adrenal steroids are normally synthesized from acetyl coenzyme A via cholesterol. Cholesterol is also shown to enter the adrenal gland and to be localized in the lipid droplets of the adrenal cortical cells. Both pregnenolone and progesterone act as intermediates in the conversion of cholesterol into steroid hormones. During pregnancy an increased level of plasma cholesterol is known to be associated with an increase of the adrenal corticoid and progesterone. The present study is designed to demonstrate whether the adrenal cortical cells show any dynamic changes during pregnancy.
