Magnetic Isotope Theory of the Origin of Life on Earth

The authors have proposed a new of magnetic isotope theory of life on Earth. According to this theory the initial impetus for the beginning of the synthesis of organic compounds is the impact of electromagnetic radiation from the sun and energy radioactive isotopes.

Motoyosi Sugita—A “Widely Unknown” Japanese Thermodynamicist Who Explored the 4th Law of Thermodynamics for Creation of the Theory of Life

The purpose of this paper is to introduce to you, the Western people, nowadays a “widely unknown” Japanese thermodynamicist by the name of Motoyosi Sugita and his study on the thermodynamics of transient phenomena and his theory of life. This is because although he was one of the top theoretical physicists in Japan before, during and after WWII and after WWII he promoted the establishment of the biophysical society of Japan as one of the founding members, he himself and his studies themselves have seemed to be totally forgotten nowadays in spite that his study was absolutely important for the study of life. Therefore, in this paper I would like to present what kind of person he was and what he studied in physics as a review on the physics work of Motoyosi Sugita for the first time. I will follow his past studies to introduce his ideas in theoretical physics as well as in biophysics as follows: He proposed the bright ideas such as the quasi-static change in the broad sense, the virtual heat, and the field of chemical potential etc. in order to establish his own theory of thermodynamics of transient phenomena, as the generalization of the Onsager-Prigogine’s theory of the irreversible processes. By the concept of the field of chemical potential that acquired the nonlinear transport, he was seemingly successful to exceed and go beyond the scope of Onsager and Prigogine. Once he established his thermodynamics, he explored the existence of the 4th law of thermodynamics for the foundation of theory of life. He applied it to broad categories of transient phenomena including life and life being such as the theory of metabolism. He regarded the 4th law of thermodynamics as the maximum principle in transient phenomena. He tried to prove it all life long. Since I have recently found that his maximum principle can be included in more general maximum principle, which was known as the Pontryagin’s maximum principle in the theory of optimal control, I would like to explain such theories produced by Motoyosi Sugita as detailed as possible. And also I have put short history of Motoyosi Sugita’s personal life in order for you to know him well. I hope that this article helps you to know this wonderful man and understand what he did in the past, which was totally forgotten in the world and even in Japan.

Career Planning and Management of Healthcare Talent Based on Life Cycle Theory

This study aims to explore career planning and management strategies for healthcare talent based on life cycle theory,in order to enhance retention rates and job satisfaction among healthcare professionals.Through qualitative research methods combined with a case study of Liannan County Hospital,the study analyzes the needs and challenges faced by healthcare talent at different career stages.The findings reveal major issues confronted by healthcare talent during career planning,including compensation and benefits,career development opportunities,work environment,and organizational support.The study proposes a series of targeted management strategies,such as individualized career development paths,continuous professional training,and support for work-life balance,to promote long-term retention and career growth of healthcare talent.The conclusion emphasizes that healthcare organizations should consider the life cycle needs of healthcare talent in career planning and management to achieve optimal talent allocation and sustainable hospital development.

Environmental impact assessment of magnesium alloy automobile hub based on life cycle assessment

In order to find out the impact of aluminum alloy hub replaced by the magnesium alloy hub on environment,the resource consumption,energy consumption and pollutant emission during hub production and their service life of the two types of hubs are investigated based on the life cycle assessment(LCA)theory.The results indicate that the adverse impact on environment can be effectively reduced by the application of magnesium alloy hubs.Compared with aluminum alloy hubs,the global warming potential(GWP)and human toxicity potential(HTP)are reduced by 39.6%and 24.0%,respectively.CO2 is the main pollutant in the life cycles of the two kinds of hubs,which is generated throughout the whole life cycle including the fabrication process and the service life,while the pollutants of particles mainly come from the fabrication stage.Compared with the aluminum alloy hubs,the green effect brought by magnesium alloy hubs is mainly due to the reduction of fuel consumption caused by weight loss.

Research on goal-setting method of rock drivage based on the balance among period, cost and quality

On the basis of the analysis on the disadvantages of the original goal-setting about rock drivage, this paper defined the ＂life cycle quality＂. With project management theory and the Cobb-Douglas function, ＂quality-cost and quality-price curve model＂ and the ＂total cost-period prediction model＂ were built. Then the goal-setting method of the balance among quality, cost and period of rock drivage was constructed by finding ＂life cycle cost＂ through ＂life cycle quality＂ using ＂quality-cost and quality-price curve model＂ and ensuring period through ＂life cycle cost＂ using ＂total cost-period prediction model＂ （hereinafter referred to as the ＂three goals balance method＂）. ＂Value contribution＂ which is the value of the contribution to a mine because of rock drivage, was found in the process of constructing the ＂quality-cost and quality-price curve model＂. An industrial test was done in coal mine A with the research results, staff footage efficiency improved by 24.24%, the period shortened by 14.3%, the ＂life cycle cost＂ dropped by 2.09%, the ＂life cycle quality price＂ improved by 3.29%, and value contribution increased by 25.3%. The result shows that the new goal method setting on the basis of coal mine profit maximization can ensure construc- tion period. At the same time, it can realize cost and quality objectives and the optimization and balance of relationship among them; rewarding excavation teams by ＂value contribution＂ can combine organizational goal with personal goal, it significantly raise the employee＇s work efficiency.

What Makes Homeowners Consider Protective Actions to Reduce Disaster Risk?An Application of the Precaution Adoption Process Model and Life Course Theory

We hypothesize that for disaster risk mitigation,many households,despite being aware of their risk and possible mitigation actions,never seriously consider doing anything about them.In mitigation-focused decisions,since there is no equivalent to warning messages,the decision process is likely to evolve over an extended time.We explore what activates hurricane mitigation protective action decisions through three research questions:(1)to what extent are homeowners unengaged in protective action decision making?(2)What homeowner characteristics are associated with lack of engagement?And(3)to what extent do different life events trigger engagement in the decision-making process?We use the Precaution Adoption Process Model to conceptualize engagement as distinct from decision making;the broader protective action decision-making literature to explore drivers of engagement;and Life Course Theory to examine potential transitions from unengaged to engaged.We use survey data of homeowners in North Carolina to examine these questions empirically.Findings suggest that one-third of respondents had never engaged in protective action decisions,that life experiences differ in their occurrence frequency and effect on households’mitigation decisions,and that some events,such as renovating,reroofing,or purchasing a home may offer critical moments that could be leveraged to encourage greater engagement in mitigation decision making.
