Diabetes is a widespread illness affecting 5 per cent of the population. In diabetics the metabolism produces an excess of glucose in the blood and, as a result, a number of sufferers need doses of insulin which allows them to regulate their glucose levels.
Currently, the method of administering insulin to diabetic patients making use of emergency services for insulin dosage depends on the experience of the qualified personnel. That is, the same patient can receive different insulin doses, and in different ways, according to the doctor attending her or him.
In order to improve this system of administration, Doctor Tomás Rubio proposed in his doctoral thesis the development of a mathematical model which would facilitate predicting the exact amount of insulin needed by a patient at any time. The thesis showed that both the absorption constant (the time taken for the insulin to enter the blood and become effective) as well as the elimination constant (the time taken for the insulin to disappear), is different for each patient. Moreover, for any one patient this absorption constant varies with time.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
