Abstract

The article offers information on the challenges and methods to teach ethics in chemical engineering, using real-life cases . It further discusses the underlying principles of material and energy balances, transport processes and unit operations; the importance and challenges of behaving ethically as a professional engineer; and understand the ethical expectations of working in large global companies which often span multiple cultures and geographies.

Abstract

Background: Geographical distribution of healthcare resources is an important dimension of healthcare access. Little work has been published on healthcare resource allocation patterns in China, despite public equity concerns. Methods: Using national data from 2043 counties, this paper investigates the geographic distribution of hospital beds at the county level in China. We performed Gini coefficient analysis to measure inequalities and ordinary least squares regression with fixed provincial effects and additional spatial specifications to assess key determinants. Results: We found that provinces in west China have the least equitable resource distribution. We also found that the distribution of hospital beds is highly spatially clustered. Finally, we found that both county-level savings and government revenue show a strong positive relationship with county level hospital bed density. Conclusions: We argue for more widespread use of disaggregated, geographical data in health policy-making in China to support the rational allocation of healthcare resources, thus promoting efficiency and equity.

3. Temperature-DependentModel for the Prediction ofBinary Ion Exchange Equilibria Involving Na+, K+, Ca2+and Mg2+Ions.

Abstract

The effect of temperature on theion exchange equilibrium behaviorof binary systems is studied experimentally and modeled. The studyconsiders the exchange between binary systems involving Na+, K+, Ca2+and Mg2+ions with Cl–as a nonexchanging anion on Rohm and Hass gel-typeAmberjet 1200H resin as the ion exchange medium. Experimental equilibriumdata is obtained for the six constitutive binary systems at 4.0, 25.0and 60.0 °C with a total solution concentration of 0.10 N. Thenonidealities in the solution and exchanger phases are modeled byapplying the Pitzer and Wilson models, respectively. Thermodynamicequilibrium constant and Wilson interaction parameters are modeledwith respect to temperature. The model proposed allows the influenceof temperature on the ion exchange equilibrium behavior to be predictedwell. [ABSTRACT FROM AUTHOR]
