Abstract
Purpose
Natural convection with heat transfer in porous media has been subject of extensive study in engineering due to its numerous applications. A case of particular interest is the Bénard-type flow.The paper aims to discuss this issue.
Design/methodology/approach
Based on the network simulation method in order to solve this problem, a numerical model is proposed.
Findings
Nusselt-Rayleigh correlation is determined for a broad range of Rayleigh, the dimensionless number that influences the solution, above and below the threshold which separates the conduction and convection pure mechanisms.
Originality/value
Based on the network simulation method.

Abstract
Purpose
This study aims to evaluate the effect of adding oregano and clove oil-in-water (O/W) nanoemulsions on the physico-chemical, technological and microstructural properties of minimally processed salad dressings during storage at 8 °C and 25 °C.
Design/methodology/approach
Samples were formulated with either free or encapsulated oregano and clove essential oils in O/W nanoemulsions.
Findings
Noticeable differences in the physical stability and microstructure of salad dressings were observed after 11 storage days and were less marked for the samples formulated with encapsulated oregano or clove oils in the O/W nananoemulsions. Moreover, rheological measurements revealed minor changes in the viscoelastic characteristics of the salad dressings containing the O/W nanoemulsions.
Originality/value
These findings confirm the potential of oregano and clove O/W nanoemulsions for use in minimally processed salad dressings as stabilising and technological agents.

Abstract
On September 11th, 1973, started the darkest stage in the recent history of Chile. The military and the police, at the command of General Augusto Pinochet, executed the most atrocious acts against the human dignity that the country had witnessed. The martial and technocratic leaders of the dictatorship ripped apart and redesigned the institutions of the country at their will, through to the elimination of the opposition and the systematic violation of human rights, which reached any person or group. Just a few days after the coup d’état that brought Pinochet to power, the Cardinal and Archbishop of Santiago, Raúl Silva Henríquez, and a group of churches declared themselves against the devastating violence that was gripping the country. Immediately, the religious spaces took up the lead in the defense of the most vulnerable, the persecuted, marginalized, and poor. The major effort focused on the Vicariate of Solidarity, an organization of the Catholic Church in Chile that was tasked with the promotion and defense of human rights, which offered legal and social assistance to the victims and their families. The Vicariate quickly positioned itself as a leader in search of justice against the backdrop of repression, censorship, lack of representative institutions, and prohibition of popular movements. The purpose of the present chapter is to analyze the work of the Vicariate of Solidarity and its leading role in the fight against human rights violations, strengthening social reorganization, reconciliation, and the return to democracy in Chile.

Abstract
Purpose
The purpose of this paper is to study the funding difficulties of innovative SMEs in traditional sectors (ISTS) and asks whether current conditions represent a financing market failure.
Design/methodology/approach
The study explores the financial tools available in Israel and their relevancy to ISTS by conducting in-depth interviews with different key figures in the financial industry. These include managers at venture capital (VC) funds, banks, private equity (PE) funds, mezzanine funds, as well as officials from the public sector.
Findings
In this study the authors identify the existence of a market failure relating to the funding of ISTS and suggest that the current VC, PE and mezzanine fund models cannot provide adequate financing solutions for ISTS in Israel.
Practical implications
In light of the importance of these firms to the economy, governmental intervention is required, if more innovative activity of ISTS is desired. To this end, the study proposes a funding scheme that addresses the special needs of these companies.
Originality/value
The study contributes to the literature by focussing specifically on the challenges of ISTS and by using a qualitative approach to analyzing the relevancy of different financial mechanisms to their needs.

Abstract
Provides an overview of the evolution of Spanish economic policy throughout the nineteenth century and considers the economic thought of the Spanish professor of this time. Discusses the work of Heinrich von Stackelberg while he was based in Spain from 1943. Suggests that Stackelberg’s ideas were key to the quantum leap in Spanish economic policy, abandoning utilitarian historicism which had permeated it up to then.

Abstract
Purpose
This study provides a new look at the late 19th-century university issue in Spain. Loss of self-government among universities and the state’s centralization brought a conflict between science and religion to the fore in the process of the secularization of knowledge.
Design/methodology/approach
We first delve into the anti-Darwinian framework associated with the scientific professionalization process, focusing on the case of the jurist Antonio Hernández Fajarnés (1851–1909). Secondly, we study the idea of the university that emerged from the Ateneo de Madrid, analyzing key speeches from the jurist Francisco Fernández de Henestrosa (1855–s.d.) given in 1887/88 and from the pharmacist José Rodríguez Carracido (1856–1928).
Findings
The study concludes that the Restoration Era in Spain was characterized by a generalized desire – shared by neo-Scholastics, conservatives and liberal rationalists – to improve the public university system. In this context, French influence was no doubt decisive; however, the Humboldtian university idea had already begun to have notable influence.
Originality/value
This article analyzes sources yet unknown to international research, such as the Ateneo de Madrid debates and Spanish university rectors’ inaugural speeches. It opens up a critical examination of the so-called displacement of educational principles in Spain toward a state-centered system of doctrinal moderantismo as opposed to the nation-centered system of the Cádiz liberalism. At the same time, it identifies key pockets of resistance relative to Spanish university transformation toward increased methodological secularization.

Abstract
Purpose
The purpose of this paper is to report and to regulate the users’ documentary necessities of six Mexican universities involved, in a cooperative manner and during the period of confinement by SARS-CoV-2, through the Document Delivery Service (DDS).
Design/methodology/approach
A diagnostic was conducted within the participating institutions that considered the information resources and sources, documents requested and the number of users per institution, which were counted daily for one month. This research used documentary and quantitative methods.
Findings
The authors determined that DDS is a reliable service for information supply although it is going to be necessary to adjust legal schemes and interlibrary loan policies to develop a process and to adapt this one to the current information services in the future or “in our new normality”; DDS will have a high impact on the conformation of networks of librarian cooperation.
Originality/value
This study exposed the importance of DDS as a relevant service to provide information on demand by using information and communication technologies, which is a safe way to operate, avoiding exposure to physical contact, ensuring the continuity of research processes in the communities and always monitoring and promoting the copyright.

Abstract
Purpose
The purpose of this paper is to describe internal corporate governance mechanisms in family firms as well as conflicts that may arise among shareholders and family members in the absence of specific corporate governance mechanisms.
Design/methodology/approach
After presenting theoretical concepts, the authors study the case of Spanish family firm El Corte Inglés to understand some of the corporate governance difficulties the company has experienced over the past few years.
Findings
This case illustrates how corporate governance problems can arise because the right mechanisms have not been used, leading to conflicts among family members, valuation problems and power struggles.
Practical implications
There is a need for family firms to employ suitable corporate governance mechanisms as governance complexity increases.
Originality/value
This study aims to contribute to the understanding of corporate governance problems among family members and their possible solutions.
