Antiviral capacity of sanitizers against infectious viruses in process water from the produce industry under batch and continuous conditions
2023
The presence of human enteric viruses in produce has extensively been reported. However, the significance of the quality of process water (PW) used by the produce industry and the viral inactivation capacity of water disinfection agents used to maintain the microbiological quality of PW has received limited attention. This study evaluates the antiviral disinfection efficacy of chlorine, chlorine dioxide (ClO2) and peracetic acid (PAA) at recommended operational limits in PW using hepatitis A virus (HAV), the cultivable norovirus surrogate, murine norovirus (MNV-1), and MS2 coliphages. Defined commodity representative crops (baby leaves, bell peppers, and the vegetable mix of tomatoes, cucum…
A CAN Fieldbus Based Architecture for Distributed Control Systems Implementation
2003
Abstract The application of distributed systems theory to the implementation of industrial control systems is one of the best options to develop simple, scalable and physically distributed control systems. Following this line, our group has proposed a new architecture based on Rule Nets (RN) as an HLP over CAN fieldbus for the implementation of Distributed Systems. This architecture has been applied to several control applications, obtaining excellent results. The most outstanding feature of the architecture was its simplicity in the control systems design, without any efficiency loss. New capabilities have been added to improve its features and develop new analysis tools, in order to incre…
An expert system hybrid architecture to support experiment management
2014
Specific expert systems are used for supporting, speeding-up and adding precision to in silico experimentation in many domains. In particular, many experimentalists exhibit a growing interest in workflow management systems for making a pipeline of experiments. Unfortunately, these type of systems does not integrate a systematic approach or a support component for the workflow composition/reuse. For this reason, in this paper we propose a knowledge-based hybrid architecture for designing expert systems that are able to support experiment management. This architecture defines a reference cognitive space and a proper ontology that describe the state of a problem by means of three different per…
A New HLA-Based Distributed Control Architecture for Agricultural Teams of Robots in Hybrid Applications with Real and Simulated Devices or Environme…
2011
The control architecture is one of the most important part of agricultural robotics and other robotic systems. Furthermore its importance increases when the system involves a group of heterogeneous robots that should cooperate to achieve a global goal. A new control architecture is introduced in this paper for groups of robots in charge of doing maintenance tasks in agricultural environments. Some important features such as scalability, code reuse, hardware abstraction and data distribution have been considered in the design of the new architecture. Furthermore, coordination and cooperation among the different elements in the system is allowed in the proposed control system. By integrating …
Supporting Mobile Virtual Team’s Coordination with SOA-Based Active Entities
2007
The use of IT solutions to support preparedness, response and recovery process has been envisioned as a possible way to improve the support for collaboration among the actors participating in mobile teams operating under constrained scenarios. Software applications supporting mobility have typically been conceived as functional extensions of centralized enterprise systems hosted on corporate servers. However, in this work, we focus on those mobile scenarios which go one step further in terms of interoperability requirements. This proposal aims to support the design, deployment and execution of ad-hoc collaborative business processes (workflows) in mobile networks, operating under constraine…

The Ecology of Hyperparasitoids.
2021
Hyperparasitoids are some of the most diverse members of insect food webs. True hyperparasitoids parasitize the larvae of other parasitoids, reaching these larvae with their ovipositor through the herbivore that hosts the parasitoid larva. During pupation, primary parasitoids also may be attacked by pseudohyperparasitoids that lay their eggs on the parasitoid (pre)pupae. By attacking primary parasitoids, hyperparasitoids may affect herbivore population dynamics, and they have been identified as a major challenge in biological control. Over the past decades, research, especially on aphid- and caterpillar-associated hyperparasitoids, has revealed that hyperparasitoids challenge rules on nutri…
Creative Project-based learning to boost technology innovation
2017
This paper shows the results of the application of a project-based learning methodology that blended flipped classroom and face-to-face sessions, along with creativity and lateral thinking techniques, to integrate the expected concepts and procedures of technology innovation and boost entrepreneurship among students of Master?s degree in chemical engineering. The constructive alignment between the expected learning outcomes and skills with the proposed activities and assessment methods was decisive in the design of the methodology, which tractor activity was the creation of an innovation project. The use of techniques of creativity promoted lateral thinking and originality in the definition…
Team collaboration capabilities as a factor in startup success
2018
[EN] This paper discusses the role of team collaboration as a building block for cultivating capabilities in technology-based startups. This conceptual framework draws on a literature review of innovation and entrepreneurship research to understand the intra-organization collaboration mechanisms among team members in technology-based startups. Introducing the concept of team collaboration capabilities represents a new approach to understanding the interaction conditions that give rise to new capabilities from a venture team as its organizational base. Rapid new capability building represents a competitive advantage in environments characterized by innovative technological change, known as d…
Linking Women Entrepreneurship with Social Entrepreneurship
2011
In recent times, the number of women entrepreneurs in the world has grown steadily, motivated by necessity or by reasons related to the identification and exploitation of a gap in the market via which they can exploit and develop the experience and knowledge acquired. However, a new phenomenon is emerging in the field of entrepreneurship: the creation of organizations to attain social goals. It is precisely within this new framework that women can take on a relevant role due to a certain extent to a greater sensitivity towards the social problems in their environment. In this paper, we discuss several cases of women entrepreneurs that have allowed us to relate the motives for entrepreneuria…
