Abstract
Purpose
The model incorporates key factors of membrane such as permeability and resistance, feed concentration, fluid viscosity and pressure differentials. Special emphasis is placed on the fouling mechanisms, including pore blockage and cake layer formation, which significantly impact the efficiency of the filtration process.
Design/methodology/approach
In this study, we present a numerical analysis of permeate flux through a membrane, focusing on the intricate dynamics of fouling phenomena. Utilizing the Langevin model, we simulate the permeation process to understand how various operational parameters affect the flux rates.
Findings
Our results demonstrate that fouling not only reduces the permeate flux but also alters the membrane’s hydraulic resistance over time. The results show that the increasing of the diffusion process on membrane reduces the clogging phenomenon. Hence, the increases of the transmembrane pressure reduce exponentially blocking pore process.
Originality/value
By analyzing these changes, we provide insights into optimizing membrane performance and developing strategies to mitigate clogging membrane. This research contributes to the field of membrane technology by enhancing our understanding of permeate flux behavior under fouling conditions and offering potential pathways for improving long-term operational sustainability.

Abstract
Purpose
The efficiency of an educational program on entrepreneurial competence, Training the Potential Entrepreneur. Generation of an Educational Model for Entrepreneurial Identify (PEIEO) is evaluated in this study.
Design/methodology/approach
Pre and post intervention tests were administered to an Experimental Group (EG) and a Control Group (CG). Moreover, four hypotheses are proposed (H1, H2, H3, H4) and tested on a sample of 1036 Spanish students. The following instruments were applied: Attitude Towards Entrepreneurship-Spanish adaption; Measurement Scale of Personal Initiative in Educational Settings and Scale of General Self-Efficacy. ANCOVA and the Student's t-test were applied to the results.
Findings
The results show that training in entrepreneurial identity increases the entrepreneurial potential of young people (H1). A notable increase in proactivity and being a self-starter was observed with regard to personal initiative within the EG, and for self-efficacy (H3) both of which were predictors of entrepreneurial identity. Gender was likewise a predictor (H4).
Practical implications
Young people attending the PElEO training program in entrepreneurial potential increased their levels of entrepreneurial identity, thereby confirming the effectiveness of the program.
Originality/value
The program (PEIEO) is based on the development of entrepreneurial potential, a dimension that generates entrepreneurial identity (creativity, leadership, achievement and personal control).

Abstract
Purpose
This paper aims to contextualize the process of public hospital providing services, based on the measurement of the performance of Federal University Hospitals (HUFs) of Brazil, using the technique of multivariate statistics of principal component analysis.
Design/methodology/approach
This research presented a descriptive and quantitative character, as well as exploratory purpose and followed the inductive logic, being empirically structured in two stages, that is, the application of principal component analysis (PCA) in four healthcare performance dimensions; subsequently, the full reapplication of principal component analysis in the most highly correlated variables, in module, with the first three main components (PC1, PC2 and PC3).
Findings
From the principal component analysis, considering mainly the component I, with twice the explanatory power of the second (PC2) and third components (PC3), it was possible to evidence the efficient or inefficient behavior of the HUFs evaluated, through the production of medical residency, by specialty area. Finally, it was observed the formation of two groups composed of seven and eight hospitals, that is, Groups II and IV, which shows that these groups reflect similarities, with respect to the scores and importance of the variables for both hospitals’ groups.
Research limitations/implications
Among the main limitations, it was observed incomplete data for some HUFs, which made it impossible to search for information to explain and better contextualize certain aspects. More specifically, a limited number of hospitals with complete information was dealt with for 60% of SIMEC/REHUF performance indicators.
Practical implications
The use of PCA multivariate technique was of great contribution to the contextualization of the performance and productivity of homogeneous and autonomous units, represented by the hospitals. It was possible to generate a high quantity of information, to contribute with assumptions to complement the decision-making processes in these organizations.
