Any active thing always needs power. All productive tools, machines or working systems, which are so-called productive force, would need proper driving (motive) power (force). The motive power is the heart or core of productive force, which would always want to correspond with a definite relation of production. The different driving powers (or energy resource) with power devices are completely ...

Previous research into the role of exercise motives (what people want from exercise) has overlooked the possible role of gains (what people get) and hence the possible benefits of motive fulfillment (when people get what they want). To redress this imbalance, we examined the additive and interactive effects of motives and subjective gains on exercise-specific outcomes. Young adults (N 196) comp...

Previous research has indicated that implicit motives can reliably predict which behaviors people select or decide to perform. However, so far, the question of how these motives are able to predict this action selection process has received little attention. Based on ideomotor theory, we argue that implicit motives can predict action selection when an action has become associated with a motive-...

Background. Achievement motive is defined as the intention to achieve one's goals. Achievement motive is assumed to promote clients to choices and actions toward their valuable goal, so it is an important consideration in rehabilitation. Purpose. The purpose of this study is to demonstrate the structural relationship among achievement motive on purpose in life, social participation, and role ex...

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...

Some biophysical features of the diazotroph Azospirillum brasilense Sp7-S were studied. It maintained a stable but relatively low membrane potential (v8) of about 385 mV in conditions typical of aerated soil solutions. Internal pH was also well regulated at about 7.4 from pH 6^8. The calculated proton motive force was maximal at 3220 mV in pH 5.0 medium, decreasing to zero at pH 8.8. This proto...

Expansion work recovery by two-phase ejector is known to be beneficial to vapor compression cycle performance. However, one of the biggest challenges with ejector vapor compression cycle is that the ejector cycle performance is sensitive to working condition changes which are common in real world applications. Different working conditions require different ejector geometries to achieve maximum ...

background: postpartum care at home is a post delivery care method that can be provided by public health nurses, trained health workers, or midwifery nurses. a study conducted to compare effect of two midwife visits at home to usual postpartum care on the healthy behaviors of low-risk iranian mothers. methods: a randomized controlled trial conducted on 200 mothers at a reference center for scre...
