Quantifying the performance agribusiness management model of the production chain of the Anadara tuberculosa called in Ecuador "Concha Prieta" o black shell is the object of this research. To this end, a quantitative, field, crosssectional, "ex post facto" methodology was applied, through the application of 4 structured questionnaires. It was concluded that despite the low levels of agribusiness management, the performance of the value chain reaches an intermediate level, mainly due to the relevant characteristics of the black shell, the great demand in the Ecuadorian market and neighboring countries. Keywords-Quality of life; Agribusiness Management; Value chain performance; Mangrove; Bivalve mollusk.

This paper explores a teaching methodology underpinned by the six-sigma framework, which was used to develop an academic programme between the University of Bradford and Business partner Jaguar Land Rover. The proposed methodology utilises a blended approach that integrates academic learning, through interactive classroom learning and workplacebased learning under the supervision of a Master Black Belt. Candidates within the programme develop skills in leadership, project and stakeholder management, and communication. The learning infrastructure includes peer support in which experienced learners use their acquired knowledge and understanding to support those at earlier stages. The result is an ‘Eco-system’ which develop self-sufficient networks and communities of capable engineers. Learning within the programme has triggered multiple research projects that contribute significantly to organisation knowledge, cost, and quality. Confirmation of candidate knowledge and learning is undertaken by the university using a curriculum aligned to SixSigma ‘certification’ standards.

This study explores the diffusion bonding of titanium to magnesium. The microstructural evolution and intermetallic compounds formed within the bond region are studied. The microstructure and composition of the bonds were characterized using a Scanning Electron Microscope (SEM) equipped with Energy Dispersive Spectroscopy (EDS). The mechanical properties of the bonds were evaluated using a micro-hardness test to determine the hardness variation across the joint region, while shear strength measurements were used to assess the joint strength. The results indicated that solid-state diffusion bonding of Ti6Al-4V and Mg (Az31) lead to the formation of Ti 3 Al and Ti 2 Mg 3 Al 18 reaction layers within the joint region. Evaluation of the mechanical properties of the bonds revealed that the bond strength increased with increase bonding time to 116 MPa at a bond time of 1 hr. The joint formation and strength were attributed to dispersion strengthening due to the nucleation of dispersed intermetallic compounds at the joint interface.

In recent decades, Europe has been working for a common way of reasoning about quality in higher education. Among the results of the work, standards and guidelines for quality assurance in the European higher education area (ESG), has been developed. According to these guidelines, it would be great if the universities not only develop their quality assurance systems, but that they develop the universities' quality culture. This has proved to be a challenge. Maybe because the quality culture is more of a phenomenon than a concept that can be defined.

Nonlinear optical microscopy techniques have emerged as a set of successful tools for biological imaging. Stimulated emission microscopy belongs to a small subset of pump-probe techniques which can image non-fluorescent samples without requiring fluorescent labelling. However, its sensitivity has been shown to be ultimately limited by the quantum fluctuations in the probe beam. We propose and experimentally implement sub-shot-noise limited stimulated emission microscopy by preparing the probe pulse in an intensity-squeezed state. This technique paves the way for imaging delicate biological samples that have no detectable fluorescence with sensitivity beyond standard quantum fluctuations.

The fourth industrial revolution requires that personalization processes of mass productions evolve towards flexible, interconnected, cloud production with greater automation in its machines and operations, called Industry 4.0 (I4.0). However, a homogeneous I4.0 concept, infrastructure state, and other issues are still scarce, making difficult to determinate in the specialized literature, the threshold between recent manufacturing and challenges that companies had to reach competitive advantage through I4.0 inclusion. Despite becoming one of the most popular strategies for continuous improvement, many plants are struggling to turn I4.0 into a success. Therefore, this paper analyzes the current trends of Industry 4.0 in High Performance Manufacturing (HPM), aiming to consolidate the existing knowledge on both subjects, providing a starting point for academics and practitioners seeking to implement I4.0 in plants and offering suggestions for future examination. This systematic literature review aims to synthesize, organize, and structure the stock of knowledge relating to I4.0 and HPM. The results show that HPM papers do not evidence a holistic evaluation of I.40 principles and foundations. There exists in HPM literature manufacturing practices that permit evaluate technology inclusion and their performance but not their autonomy, cloud computing and network between machines, supplier, and processes. The HPM papers trends are related with issues such as adaptability, flexibility, reconfigurability, new information technologies, modularity, automation, etc. Regarding study limitations, it is necessary to study current I4.0 adoption level, technological infrastructure, and cultural factors. The practical implications are focused in the identification of manufacturing practices used in specialized literature to measure how technology inclusion increase companies’ performance, proving the technological infrastructure and I4.0 maturity level. The originality of this paper converges on the presentation of some manufacturing practices applied on HPM studies which are associated with I4.0. Keywords-Industry 4.0, High Performance Manufacturing.
