Purpose The purpose of this paper is to provide a picture of the maintenance management status in a sample of Moroccan industries through highlighting the most impacting factors. A preliminary framework of a maintenance management model is proposed on the basis of the study findings. Design/methodology/approach A mixed methods research (MMR), including qualitative and quantitative independent studies, was conducted in a sample of Moroccan industries. The process of collecting data involved submission of questionnaires to industrial managers and on-site visits. Analyzing case studies and correlations between maintenance factors were used to define the status of maintenance management. The preliminary framework of a maintenance management model was presented through a basic graph. Findings The surveyed companies have three levels of maintenance management: inner, medium and good. The most impacting maintenance factors include the top management policy and maintenance department approach. Most of the companies surveyed do not have an overall maintenance model, as most of decisions are based on random factors rather than the data analysis approach. The preliminary framework of maintenance management model involves the main factors with recommendations to improve maintenance management performance. Research limitations/implications The sample in this study is limited to seven companies in the qualitative study and thirty-one companies in the quantitative study. The informants are the industrial managers of those companies. In order to apply this maintenance model in industry, an advanced version of this model is to be developed through providing key performance indicators (KPI) and an implementation process for each factor, including other participants in the companies from top management and operational levels. Practical implications The study may contribute to assess maintenance management and to develop a framework of maintenance management models in industries, especially when no previous basic study was conducted in a specific context. Originality/value The original contribution of this paper is using MMR to develop a preliminary framework of a maintenance management model. This methodology aims to narrow the gap between academic studies and maintenance management in industries.

The health system is a fundamental building block of a country's social project. Approaches and strategies differ but some concepts such as Patient Centred Care (PCC) seem to be more and more popular nowadays as the customer centric advocated in the industry. The research has focused on this trend of PCC with several different definitions but without having a particular focus on the context of Low and Middle Income Countries (LMICs). The objective of this study is, through an extensive literature review, to analyze this concept, to unify the dimensions described by different authors, to define a concept that can be proposed to LMICs and to determine facilitating factors as well as obstacles for its implementation. Keywords: Conceptual model, Health system, Low and middle income countries (LMICs), Patient Centered Care

Growing energy demand is causing a significant decrease in the world’s hydrocarbon stock in addition to the pollution of our ecosystem. Based on this observation, the search for alternative sorts of energy to fossil fuels is being increasingly explored and exploited. Wind energy is experiencing a very important development, and it offers a very profitable opportunity for exploitation since the wind is always available and inexhaustible. Several technical solutions exist to exploit wind energy, such as floating vertical axis wind turbines (F-VAWTs), which provide an attractive and cost-effective solution for exploiting higher resources of offshore wind in deep water areas. Recently, the use of the Darrieus vertical axis wind turbine (VAWT) offshore has attracted increased interest because it offers significant advantages over horizontal axis wind turbines (HAWTs). In this context, this article presents a new concept of floating Darrieus-type straight-bladed turbine with three-stage rotors. A double-multiple stream tube (DMST) model is used for aerodynamic simulations to examine several critical parameters, including, solidity turbine, number of blades, rotor radius, aspect ratio, wind velocity, and rotor height. This study also allows to identify a low solidity turbine (σ = 0.3), offering the best aerodynamic performance, while a two-bladed design is recommended. Moreover, the results also indicate the interest of a variable radius rotor, as well as the variation of the height as a function of the wind speed on the aerodynamic efficiency.
