Can free energy be transduced from electric noise?
Recently, it was shown that free energy can be transduced from a regularly oscillating electric field to do chemical or transport work when coupled through an enzyme with appropriate electrical characteristics. Here we report that randomly pulsed electric fields can also lead to work being done, giving rise to speculation as to whether appropriately designed enzymes can extract and convert free...
متن کاملHow enzymes can capture and transmit free energy from an oscillating electric field.
Recently, it has been demonstrated that free energy from an alternating electric field can drive the active transport of Rb+ by way of the Na+, K+-ATPase. In the present work, it is shown why many transmembrane enzymes can be expected to absorb free energy from an oscillating electric field and transduce that to chemical or transport work. In the theoretical analysis it turned out to be suffici...
متن کاملWhy Information can be Free
This paper describes a model that demonstrates that sharing knowledge can be adaptive purely for its own sake. This is despite the fact that sharing knowledge costs the speaker in terms of foraging opportunities, and that initially the majority of the population consists of free-riders who listen but do not speak. The population is able to take advantage of the increased carrying capacity of th...
متن کاملCan Acceptable Noise Levels Be Predicted from a Noise - Tolerance Questionnaire ?
The Acceptable Noise Level (ANL) test is a measure of the amount of background noise that a person is willing to tolerate. In recent years it has gained interest among researchers and hearing care professionals because of its ability to predict, with 85% accuracy, who will be successful with hearing aids. This statistic is not only useful for counselling purposes, but it implies that if one cou...
متن کاملHow can Alzheimer's Patients be Helped?
پرستاری از بیمار مبتلا به بیماری آلزایمر چندان ساده نیست. حتی اگر از این امر که اختلال رفتاری فرد نشانه ای از بیماری اوست، آگاه باشید، اکثر مواقع نمی دانید که چگونه باید با او رفتار کنید. در این مقاله روشهای مناسبی ارائه گردیده تا خانواده بیمار بتواند با ۱۰ اختلال رفتاری شایع در بیماران مبتلا بدون احساس ناامیدی و خشم سازگاری یابند.
