It has been previously shown that the implicit affiliation motive - the need to establish and maintain friendly relationships with others - leads to chronic health benefits. The underlying assumption for the present research was that the implicit affiliation motive also moderates the salivary cortisol response to acute psychological stress when some aspects of social evaluation and uncontrollab...
It is generally accepted that the chemistry of water was the most crucial determinant in shaping life on earth. Among the more important chemical features of water is its dissociation into protons and hydroxyl ions. The presence of relatively high proton concentrations in the ambient solution resulted in the evolution of proton pumps during the dawn of life on earth. These proton pumps maintain...
The microaerophilic nitrogen-fixing bacterium Azospirillum brasilense formed a sharply defined band in a spatial gradient of oxygen. As a result of aerotaxis, the bacteria were attracted to a specific low concentration of oxygen (3 to 5 microM). Bacteria swimming away from the aerotactic band were repelled by the higher or lower concentration of oxygen that they encountered and returned to the ...
This paper revisits the debate on altruism vs exchange motive for bequest and studies to what extent the saving behavior of elderly Europeans is di↵erent in the presence or absence of adult children. To this purpose, we develop a structural model with two overlapping generations, namely elderly parents and their adult children. For each generation, we formulate a separate lifecycle model in whi...
Detailed physiological studies were done to compare the influence of environmental pH and fermentation end product formation on metabolism, growth, and proton motive force in Sarcina ventriculi. The kinetics of end product formation during glucose fermentation in unbuffered batch cultures shifted from hydrogen-acetate production to ethanol production as the medium pH dropped from 7.0 to 3.3. At...
“The Book of Al Sawad” is the part that Adonis has devoted to Cafour in his famous trilogy: Book: Yesterday Place Now, after reviewing Sayf Dawla's papers, and papers Khawla, complete biography Mutanabbi book. The recipient's memory two images for Cafour, paradoxically, contradictory, first positive historical witnessed by what was said history books, a satirical poetic picture, Al-Mutanabbi dr...
The ethical implications of the growth of for-profit health care institutions are complex. Two major moral criticisms of for-profit medicine are analyzed. The first claim is that for-profit health care institutions fail to fulfill their obligations to do their fair share in providing health care to the poor and so exacerbate the problem of access to health care. The second claim is that profit ...
Recent theoretical progress in nonequilibrium thermodynamics, linking the physical principle of Maximum Entropy Production (“MEP”) to the information-theoretical “MaxEnt” principle of scientific inference, together with conjectures from theoretical physics that there may be no fundamental causal laws but only probabilities for physical processes, and from evolutionary theory that biological sys...
This study explored the role of the proton motive force in the processes of DNA binding and DNA transport of genetic transformation of Bacillus subtilis 168 strain 8G-5 (trpC2). Transformation was severely inhibited by the ionophores valinomycin, nigericin, and 3,5-di-tert-4-hydroxybenzylidenemalononitrite (SF-6847) and by tetraphenylphosphonium. The ionophores valinomycin and nigericin also se...
