Comparative Analysis of Hydrogen Production and Economic Feasibility: Direct versus Indirect Coupling of Photovoltaic Systems with Electrolyzers

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This article examines the efficiency and cost‐effectiveness of green hydrogen production strategies: direct and indirect, with and without battery. Results show that the indirect configuration with battery yields the highest hydrogen production and profitability. The study discusses technical, energetic, and economic trade‐offs, providing insights into

TRANSCRIPTIONAL REGULATION BY CYCLIC AMP

Annual Review of Biochemistry, 1997
A number of hormones and growth factors have been shown to stimulate target cells via second messenger pathways that in turn regulate the phosphorylation of specific nuclear factors. The second messenger cyclic AMP, for example, regulates a striking number of physiologic processes, including intermediary metabolism, cellular proliferation, and ...

Cyclic AMP

International Journal of Oral Surgery, 1978
Cyclic AMP mediates the effects of many hormones on their target cells. Some of the mechanisms by which this occurs are discussed in this review. The role of cyclic AMP in regulating glycogen metabolism in liver and skeletal muscle is firmly established.

Cyclic di-AMP Signaling in Bacteria.

Annual Review of Microbiology, 2020
The second messenger molecule cyclic di-AMP (c-di-AMP) is formed by many bacteria and archaea. In many species that produce c-di-AMP, this second messenger is essential for viability on rich medium. Recent research has demonstrated that c-di-AMP binds to

Cyclic AMP signalling

Journal of Cell Science, 2001
![Figure][1] Cyclic adenosine 3′,5′-monophosphate (cAMP) was the first identified second messenger. A large number of studies during the past 30 years have elucidated the fundamental role of cAMP in the cellular response to many hormones and neurotransmitters.

Cyclic AMP in Metobolism

Nature New Biology, 1971
Throughout the animal kingdom cyclic AMP is involved in the regulation of enzyme activity under the influence of hormones. As this review shows, a few clues are beginning to emerge about the way in which this is being achieved.

Altered cyclic AMP-binding and db cyclic AMP-unresponsiveness in vivo [PDF]

open access: possibleNature, 1977
CYCLIC AMP has been implicated in the regulation of cell growth. However, the molecular mechanism of cyclic AMP action, especially that involving the control of tumour growth in vivo is not clear. Our previous studies on two cell populations of Walker 256 mammary carcinoma (W256), one regressing (responsive), the other growing (unresponsive) under ...

Cyclic AMP and Anxiety

Psychosomatics, 1972
• The history of research on various neurohumors that control behavior appears to be very cyclical; each decade having a favorite chemical mediator implicated in behavioral control and in psychotropic drug action. Before 1950 the focus was on acetylcholine as an important element in brain function, mainly because of its involvement in peripheral and ...

Cyclic AMP and cyclic GMP in hyperresponsiveness

Life Sciences, 1988
Cyclic-AMP has been shown to cause a hyperresponse in blood pressure change in conjunction with norepinephrine in the anesthetized rat system. Recent experiments show that the antagonist to angiotensin II, Sar1-Thr8 angiotensin II, abolishes the hyperresponse produced by c-AMP.
