This paper aims to use an imidazole-based n-ionic Gemini surfactant derived from palm oil to inhibit the sulfide stress corrosion cracking of a supermartensitic stainless steel.

The slow strain rate testing technique, hydrogen permeation tests and potentiodynamic polarization curves have been used.

Addition of the inhibitor below the critical micelle concentration (CMC) decreased the corrosion current density (i_corr), but not enough to avoid embrittlement due to the entry of hydrogen into the steel. Instead, the addition of the inhibitor close to the CMC decreased the i_corr, suppressed the entry of hydrogen and inhibited the sulfide stress cracking of steel. Finally, the addition of inhibitor above the CMC led to a slight increase of i_corr and promoted localized corrosion, however, the sulfide stress cracking of steel was inhibited.

A green sulfide stress corrosion cracking inhibitor of a supermartensitic stainless steel has been obtained.

The process of chronic pain (CP) and strategies is to improve the patient’s health and well-being. CP is a frequent medical problem that presents a major challenge to healthcare providers because of its complex natural history, imprecise aetiology, and inadequate response to pharmacological treatment. Although different definitions exist it is widely accepted that CP is an ongoing pain that lasts more than 3 months or that persists longer than the reasonably expected healing time for the involved tissues. Also, it is acknowledged that its treatment is much different than the treatment for acute pain. When addressing a person with CP, one should always keep in mind that pain is much more about the individual than the underlying medical condition. Every person is different, and healthcare providers should take a tailor-made approach to managing their pain. This is the only way to ensure good results in pain treatment. Treatment goals should be discussed and adapted to the patient profile. It is fundamental to have clear goals from the beginning and to ensure these are realistic, individualized, and measurable. Effective treatment for CP is only achieved through a holistic framework in which the patient’s well-being is the first concern and an interdisciplinary and societal approach is implemented from the first day.

The purpose of this paper is to review the contributions of what has been established as Latin American thought, as science, technology, and innovation (STI) in Latin America have been strongly related to development.

The analysis method is based on the review of a group of Latin American and Latinoamericanista (Latin Americanist) authors who were selected on the basis of their contributions to the explanation and proposals of public policy related to STI. The following are some of the questions that guide the analysis. How much has STI in Latin American thought contributed to the development theory? Given the fact that there are other dominant mainstreams, can we say that Latin American thought is still relevant?

The main conclusion of this work is that Latin American thought is still applied to current Latin American development discussions. This can be proven by the creation of particular concepts and analytical frameworks such as structural heterogeneity, development styles, authentic and spurious competitiveness, Sabato’s Triangle, the centre-periphery model, and STI policy practices.

This paper gathered contributions and categorised them into three dimensions: state participation (intensity, composition), industrialisation as the impulse for development, and instruments and public policy actions that can be implemented or have already been implemented.

El propósito de este trabajo es el de reflexionar sobre algunas aportaciones provenientes de lo que hemos denominado pensamiento latinoamericano en relación con la innovación, la ciencia, la tecnología y su relación con el desarrollo.

El método de análisis se basa en la revisión de un conjunto de autores latinoamericanos y latinoamericanistas que hemos seleccionado con base en sus aportaciones para la explicación y sus propuestas de política pública en relación con la CTI. Algunas preguntas que guían nuestro análisis son las siguientes: ¿en qué medida el pensamiento latinoamericano en CTI ha contribuido a la teoría del desarrollo? y ¿dada la existencia de otros enfoques que predominan como pensamiento único, podemos hablar de una vigencia del pensamiento latinoamericano?

La principal conclusión de nuestro trabajo es que hay un pensamiento latinoamericano vigente que ha sido y aún es un referente actual para la discusión del desarrollo en la región latinoamericana, como lo muestran la creación de conceptos y esquemas analíticos como los de heterogeneidad estructural, estilos de desarrollo, la competitividad auténtica y espuria, el Triángulo de Sábato, centro-periferia, así como estrategias de política en CTI.

Como parte del marco analítico hemos agrupado al conjunto de aportaciones en tres direcciones: a) la participación del Estado (intensidad, composición); b) la industrialización como impulso al desarrollo y c) los instrumentos y medidas de política pública a implementar o que han sido implementados.

This study develops an integrated zero waste discharge planning approach for improving resource efficiency in a pulp-and-paper manufacturing firm.

The findings demonstrate the superiority of hybrid particle swarm optimization algorithm in generating optimal results for a pulp-and-paper manufacturing firm.

The findings demonstrate the superiority of hybrid particle swarm optimization algorithm in generating optimal results for a pulp-and-paper manufacturing firm.

Resource efficiency is a multi-objective problem in an uncertain environment. In particular, zero waste discharge planning involves minimizing the total cost and maximizing the waste material recovery rate, wastewater reuse, and waste heat recovery.

The purpose of this paper is to translate consumer requirements regarding olive-oil quality attributes into specific olive-growing practices that most contribute to satisfy these attributes.

After identifying consumer requirements or needs regarding different attributes of olive-oil quality, through a survey of 439 olive-oil consumers, the authors determine the olive-growing practices that optimally satisfy consumer needs through expert opinions. Finally, the use of expert knowledge to construct the House of Quality or the first matrix of quality function deployment allow the authors to define the relative contribution of the various olive-farming practices to the satisfaction of consumer requirements.

The findings have shown that the olive-oil quality attributes most requested by consumers incorporate organoleptic (e.g. acidity, flavour, colour), sociocultural (e.g. creating employment in rural areas, maintenance of the rural population) and environmental ones (environmental externalities). The “separation of olives collected from ground and trees” (separation), “timing of harvesting” (according to a fruit-ripeness index), the “method of the ground harvest” (no picking from the ground), and the “method of tree harvest” (handpicking) were some of the most commonly identified olive-farming practices that contribute the most to meeting consumers’ needs with regard to olive-oil quality.

The study suggests detailed analyses of the relationships between customer requirements and other agents practices involved in the olive sector (processing industries: mills, distribution, and marketing management, etc.) to more fully investigate the impact of all these practices on consumers’ perceived olive-oil quality attributes. This is the most reliable way to guarantee that the most sought-after quality characteristics are taken into account, not only in the farming stage but also in the various different stages of the olive agri-food chain.

Findings represent an opportunity in the market value chain to develop a quality olive oil which is more oriented towards the consumer and able to face future segmentations in the market. This is one of the main innovative features of this study, as it offers “good practice” guidelines to agents of the olive-oil sector from the consumer perspective.

This study provides positive implications to consumers, providing them important tools to make an informed choice, and producers and marketers helping the design of production strategies to optimally satisfy the consumer preference with regard to olive-oil quality, and attain a competitive advantage by adding value to the product.

This paper is regarded as the pioneer in the literature translating the “consumer voice” regarding olive-oil quality into specific olive-growing practices “good-practices guidelines”. Thus, the relevant required quality olive-oil attributes should be clearly described on the label, to enable consumers to identify the quality features and make an informed choice. Furthermore, to meet consumers’ needs, the olive-oil sector should focus on the olive-growing practices that optimally satisfy consumer requirements concerning olive-oil quality attributes. This would help to improve legitimacy and boost public support for the Common Agricultural Policy subsidies for the agricultural sector in general, and the olive sector in particular. The findings are particularly valuable in helping policy makers to design marketing strategies to improve the sustainability and competitiveness of Spanish olive oil.

The purpose of this paper is to analyze the relationship between Latin American migrants and the Spanish healthcare system, from the users’ perspective, in order to examine the socio-cultural determinants for access and attention, as well as the possible difficulties faced when attending institutional facilities.

This work is based on qualitative ethnographic research with the Latin American community established in the region of Castile and León, Spain. Analysis was established through a thematic approach and illustrated with the testimonies of participants involved, to inspect personal meanings and interpretations, as well as specific practices regarding healthcare.

The encounter between foreigners and health services is frequently expressed with negative emotions, such as feelings of fear facing a system that is perceived as designed “for others.” For many Latin American immigrants in Spain, institutional healthcare is not considered their first choice for treating illness. This has been related to economic, bureaucratic, ideological and emotional factors.

Most of the existing literature about immigrant healthcare in Spain has focused on sanitary conditions or patterns of service use from an institutional perspective and a quantitative approach. This paper highlights the perceptions of users to enrich comprehension of the rapport between migrants and medical care.

The study aims to evaluate the effect of inducing emotions (neutral, joy and fear) on the level of visual attention in beer advertisements.

A between-subject experimental study with a multi-method design was carried out using three neuroscience equipment concomitantly. The electroencephalogram and the electrical conductance sensor on the skin were used to assess the emotions induced in the individuals, while eye-tracking was used to assess the visual attention to beer advertisements. Three independent groups were formed. Each group was induced to one emotion (neutral, joy or fear), and then the level of visual attention was observed in ten stimuli of beer advertisements.

The results revealed that the induction of joy increased the visual attention to the brand name, while the induction of fear increased the visual attention to both the brand name and product packaging but reduced the visual attention to human faces within the ads.

This paper extends the literature, and to the best of the authors’ knowledge, it is the first study to indicate that induced emotions before ad viewing influence potential consumers’ visual attention.

The findings can serve as a basis for developing advertising campaigns that use emotion induction before ad viewing to increase the visual attention of potential consumers.

To the best of the authors’ knowledge, this is the first study to investigate whether the emotion induction that happens before ad viewing can impact the level of visual attention to advertisements. The study also provides clear and comprehensible implications from marketing practices to improve visual attention to ads.

The purpose of this study is to analyse Benidorm, San Sebastián, Gijón, Málaga, Tenerife Island and Santander smart tourist destinations (STDs) as a touristic model and example to follow by other destinations in Spain and all over the world.

To fulfil the stated objective, this study follows several phases that introduce and classify a set of measures implemented by the six Spanish smart destinations to be designed as a STD.

Findings suggest that being a STD requires a high cost, and this is only accessible to big destinations with enough resources. Of the 50 Spanish provinces, eight are STDs, and these are localised in coastal areas. Obviously, this challenge is not within the reach of any Spanish city. Moreover, findings of the current study prove that the six Spanish smart destinations have a good air accessibility through their six airports, but the accessibility in a STD is not just physical; this must provide digital accessibility to tourists through destination marketing organisation’s website and app that will supply them with information on a wide range of services, including accommodations, tourist attractions, restaurants, public transport, museums and monuments’ locations, amongst many others.

From a resident point of view, a STD cannot be only focused on a technological and tourism context; a STD also requires knowing and meeting the needs of local residents and having a voice in decision-making processes. Hence, this study shows a new perspective on STDs that will benefit the literature on STDs.

The aim of this paper is to solve the toxic and harmful problems caused by traditional volatile corrosion inhibitor (VCI) and to analyze the effect of the layered structure on the enhancement of the volatile corrosion inhibition prevention performance of amino acids.

The carbon dots-montmorillonite (DMT) hybrid material is prepared via hydrothermal process. The effect of the DMT-modified alanine as VCI for mild steel is investigated by volatile inhibition sieve test, volatile corrosion inhibition ability test, electrochemical measurement and surface analysis technology. It demonstrates that the DMT hybrid materials can improve the ability of alanine to protect mild steel against atmospheric corrosion effectively. The presence of carbon dots enlarges the interlamellar spacing of montmorillonite and allows better dispersion of alanine. The DMT-modified alanine has higher volatilization ability and an excellent corrosion inhibition of 85.3% for mild steel.

The DMT hybrid material provides a good template for the distribution of VCI, which can effectively improve the vapor-phase antirust property of VCI.

The increased volatilization rate also means increased VCI consumption and higher costs.

Provides a new way of thinking to replace the traditional toxic and harmful VCI.

For the first time, amino acids are combined with nano laminar structures, which are used to solve the problem of difficult volatilization of amino acids.
