Article Abstract
Response surface methodology (RSM) has been widely used to identify optimal conditions for environmental microorganisms to maximize degrading pollutants and accumulating biomass. However, to date, environmental impact and economic cost have rarely been considered. In this study, a single cell of microalgae Chlorella sorokiniana ZM-5 was sorted, and its enrichment was carried out for the first time. The optimized conditions by RSM for achieving the highest COD, TN, TP removal and 352.61 mg/g lipid production were 24 h light time, 4.3:1C/N, 7.2 pH, and 30 °C temperature, respectively. Life-cycle approaches were then carried out upon this illustrative case, and the results indicated that the implementation of the above optimal conditions could reduce the total environmental impact by 48.0% and the total economic impact by 10.2%. This study showed the feasibility of applying life-cycle approaches to examine the optimal conditions of a biological process in terms of minimizing environmental impact and economic costs.

Azo dyes, prevalent in various industries, including textile dyeing, food, and cosmetics, pose significant environmental and health risks due to their chemical stability and toxicity. This study introduces the synthesis and application of a copper hydrogen-π-bonded benzoate framework (Cu-HBF) and its derived marigold flower-like copper oxide (MFL-CuO) in a synergetic adsorption-photocatalytic process for efficiently removing cationic azo dyes from water, specifically crystal violet (CV), methylene blue (MB), and rhodamine B (RhB). The Cu-HBF, previously available only in single crystal form, is prepared here as a crystalline powder for the first time, using a low-cost and facile procedure, allowing its application as an adsorbent and also serving as a precursor for synthesizing well-structured copper oxide (MFL-CuO).

Mixed-integer (MI) quadratic models subject to quadratic constraints, known as All- Quadratic MI Programs, constitute a challenging class of NP-complete optimization problems. The particular scenario of unbounded integers defines a subclass that holds the distinction of being even undecidable. This complexity suggests a possible soft-spot for Mathematical Programming (MP) techniques, which otherwise constitute a good choice to treat MI problems.

Background: Cirrhosis is a leading cause of noncancer deaths in gastrointestinal diseases, resulting in high hospitalization and readmission rates. Early identification of high-risk patients is vital for proactive interventions and improving health care outcomes. However, the quality and integrity of real-world electronic health records (EHRs) limit their utility in developing risk assessment tools.

The CO cycloaddition route is an effective way to achieve efficient conversion and utilization of CO. Zeolites with diverse topologies and tunable acidic sites can efficiently promote the cycloaddition reaction of CO with epoxides. The exchangeable cations in zeolites have a great influence on the performance of the CO cycloaddition, but there are few studies on it.

Objective: Aim: To provide a scientific rationale for various approaches to the practical application of individual motivation theories in order to develop a motivated medical workforce as the foundation for strengthening healthcare systems.
Patients And Methods: Materials and Methods: Based on comparative analysis, as well as systematic and analytical approaches to understanding selected motivation theories - namely Maslow's Hierarchy of Needs, Herzberg's Two-Factor Theory, Adams's Equity Theory, Vroom's Expectancy Theory, and Deci and Ryan's Self-Determination Theory - the authors propose integrating these theories into managerial strategies.
Conclusion: Conclusions: A well-functioning healthcare workforce system requires not only a sufficient number of professionals but also effective motivation strategies based on various theories, such as those by Maslow, Herzberg, and Vroom, to enhance job satisfaction and retention.
