The lightest flavor--singlet qqq baryons as witnesses to color

We present a new computation in a field-theoretical model of Coulomb gauge QCD of the first radial and angular excitations of a qqq system in a SU(3) flavor singlet state, Lambda_S. The traditional motivation for the study is that the absence of flavor singlets in the lowest-lying spectrum is a direct consequence of the color degree of freedom. (The calculation is tested with decuplet baryons Delta(1232) and Omega(1672).) We also analyze decay branching fractions of the flavor singlet baryon for various masses with the simplest effective Lagrangians

Agronomic biofortification with magnesium nanofertilizer and its effect on the nutritional quality of beans

Crop quality has been compromised due to nutrient deficiencies. The macronutrient magnesium (Mg) is essential; however, it has not been considered in agronomic fertilization programs, affecting human health. The objective of the study was to increase the Mg content in the fruits of green beans cv. ‘Strike’ by applying Mg-nanofertilizer, as well as evaluating its effect on growth, performance and nutritional quality, versus magnesium sulfate (MgSO4). The experiment was carried out under shade mesh conditions in Delicias, Chihuahua, Mexico during the period August-October 2022. A completely randomized experimental design was used, with two Mg sources: Mg nanofertilizer (NanoMg) and MgSO4 at doses of 50, 100 and 200 ppm and a control without application, forming seven treatments with six repetitions each. The results indicate that the maximum yield was provided by NanoMg and MgSO4 at 200 ppm, with values greater than 300%. The Mg distribution pattern for the NanoMg treatments presented the following concentration order: root>leaf>stem>fruit; while, for the MgSO4 treatments it was: leaf>root>stem>fruit. The most efficient treatment in increasing the Mg content in the fruit was NanoMg at 200 ppm, which achieved a biofortification of more than 120% with respect to the control. Therefore, when consuming 100 g of green beans cv. ‘Strike’ biofortified by NanoMg, the recommended daily needs of the human being could be satisfied. Finally, it is concluded that nanofertilizers are the best option for a biofortification program since they offer a sustainable alternative by increasing productivity and quality in green bean fruits

Evaluación de las asociaciones público privadas en el área metropolitana de Monterrey: Nivel de satisfacción en la prestación del servicio a los usuarios

La competitividad de los países en los diferentes ámbitos de la vida pública no se alcanza tan solo con el desempeño del sector privado, se requiere contar con un gobierno con estas mismas condiciones con las que se participa en lo privado, además de un alto desempeño. Sin embargo, cuando la administración pública no está en condiciones de ofrecer un servicio de calidad, este sedera dicho servicio a una concesión quien genere las condiciones para llevar con eficiencia y eficacia el servicio público municipal. Por otra parte los grandes cambios que se han estado dando en la prestación del servicio en la Administración Pública, han sigo generales en un contexto global, los países, incluyendo a México han iniciado procesos enfocados a reformas y modernización de la administración pública orientados a adecuarse a las nuevas demandas de la ciudadanía. Es necesario renovar los mecanismos y procesos de las instituciones de Gobierno con el fin de permitir que la administración pública responda con éxito a las exigencias de la sociedad. Contar con una modernización administrativa no solo exige desarrollar instituciones que promuevan el mejor desempeño de los funcionarios y permitan racionalizar el gasto, sino también crear procesos que hagan más flexible y legitimen la relación entre Gobierno y ciudadano

Light‐Emitting Diodes: Progress in Plant Micropropagation

In commercial micropropagation laboratories, the light source is one of the most important factors controlling plant morphogenesis and metabolism of plant cells and tissue and organ cultures. Lamp manufacturers have begun to rate lamps specifically for plant needs. The traditional light source used for in vitro propagation is fluorescent lamps (FLs). However, power consumption in FL use is expensive and produces a wide range of wavelengths (350–750 nm) unnecessary for plant development. Light‐emitting diodes (LEDs) have recently emerged as an alternative for commercial micropropagation. The flexibility of matching LED wavelengths to plant photoreceptors may provide more optimal production, influencing plant morphology and chlorophyll content. Although previous reports have confirmed physiological effects of LED light quality on morphogenesis and growth of several plantlets in vitro, these study results showed that LED light is more suitable for plant morphogenesis and growth than FLs. However, the responses vary according to plant species. This chapter describes the applications and benefits of LED lamps on chlorophyll in plant micropropagation. Two study cases are exposed, Anthurium (Anthurium andreanum) and moth orchids (Phalaenopsisis sp.), both species with economic importance as ornamental plants, where LEDs have a positive effect on in vitro development and chlorophyll content

Development of Antibody-Coated Magnetite Nanoparticles for Biomarker Immobilization

Magnetic nanoparticles (MNPs) have great potential in biomedical applications because of their magnetic response offers the possibility to direct them to specific areas and target biological entities. Magnetic separation of biomolecules is one of the most important applications of MNPs because their versatility in detecting cancer biomarkers. However, the effectiveness of this method depends on many factors, including the type of functionalization onto MNPs. Therefore, in this study, magnetite nanoparticles have been developed in order to separate the 5′-nucleotidase enzyme (5eNT). The 5eNT is used as a bio-indicator for diagnosing diseases such as hepatic ischaemia, liver tumor, and hepatotoxic drugs damage. Magnetic nanoparticles were covered in a core/shell type with silica, aminosilane, and a double shell of silica-aminosilane. A ScFv (fragment antibody) and anti-CD73 antibody were attached to the coated nanoparticles in order to separate the enzyme. The magnetic separation of this enzyme with fragment antibody was found to be 28% higher than anti-CD73 antibody and the enzyme adsorption was improved with the double shell due to the increased length of the polymeric chain. Magnetite nanoparticles with a double shell (silica-aminosilane) were also found to be more sensitive than magnetite with a single shell in the detection of biomarkers

Education and innovation - vet students into technology companies

VET education is an effective and accessible way for students, to improve their employability and inclusion possibilities. It allows them to train technically in a short time to do a job and try to access the labor market. However, not even obtaining a qualification aimed at vocational training ensures access to the labor market or real possibilities of emancipation. The success of VET graduates in their first work experience joining technology companies requires the development of many skills that are common to all professional careers, but also specific skills that derive from the innovative nature of the work method and objectives of these companies. For this reason, within the framework of the Erasmus + Program, the project VET STUDENTS İNTO TECHNOLOGY COMPANİES: A VET students mobility network in the technological sector through a virtual environment with specific materials for critical thinking is being developed with the aim of promoting employability and inclusion of VET students at risk of exclusion. The project focuses on the creation of virtual tools, collaborative work methodologies and virtual training materials that allow these young people to improve their critical thinking capacity and their technological and digital skills. The project's methodology is based on the combination of the creation of training materials and a network of mobility in high-tech centres, where students will carry out a first work experience. Regarding training materials, one of the main results of this project is PERSONALIZED DIGITAL COURSE FOR LABOR TRAINING IN A TECHNOLOGICAL CENTER. This course generates personalized learning based on the student's previous knowledge and the characteristics of the technological company in which they will carry out their internship. The course follows an innovative methodology based on microlearning, a learning characterized by the resolution of relatively small exercises (pills) that are focused on the development of technical and work skills and the reinforcement of critical thinking as a fundamental mechanism. The objective of this course is not so much to provide new knowledge as to develop skills that allow the students to face problems or tasks unknown to them until then: self-training skills, assess their own way of reasoning, set objectives, raise relevant questions, state hypothesis, search for information, intellectual integrity, oral and written communication, work in multidisciplinary teams. Along with this course, within the framework of this project, the result ON YOUR SIDE is being developed, a digital educational software available for mobile devices, which will accompany the student throughout the mobility process, providing useful information such as specific training resources focused on the company where they will carry out their mobility, linguistic resources, collaborative work tools, as well as social integration resources in the destination country, among others. From this App, students will be able to access the aforementioned course. In this paper we present how, through microlearning methodology and critical thinking, students can solve the content pills through their autonomy and self-discovery.This work has been funded by the Erasmus + program within the 2019-1-ES01-KA202-064569 project, Spanish Service for the Internationalization of Education (SEPIE

Production of highly bioactive resveratrol analogues pterostilbene and piceatannol in metabolically engineered grapevine cell cultures

Summary Grapevine stilbenes, particularly trans-resveratrol, have a demonstrated pharmacological activity. Other natural stilbenes derived from resveratrol such as pterostilbene or piceatannol, display higher oral bioavailability and bioactivity than the parent compound, but are far less abundant in natural sources. Thus, to efficiently obtain these bioactive resveratrol derivatives, there is a need to develop new bioproduction systems. Grapevine cell cultures are able to produce large amounts of easily recoverable extracellular resveratrol when elicited with methylated cyclodextrins and methyl jasmonate. We devised this system as an interesting starting point of a metabolic engineering-based strategy to produce resveratrol derivatives using resveratrolconverting enzymes. Constitutive expression of either Vitis vinifera resveratrol O-methyltransferase (VvROMT) or human cytochrome P450 hydroxylase 1B1 (HsCYP1B1) led to pterostilbene or piceatannol, respectively, after the engineered cell cultures were treated with the aforementioned elicitors. Functionality of both gene products was first assessed in planta by Nicotiana benthamiana agroinfiltration assays, in which tobacco cells transiently expressed stilbene synthase and VvROMT or HsCYP1B1. Grapevine cell cultures transformed with VvROMT produced pterostilbene, which was detected in both intra- and extracellular compartments, at a level of micrograms per litre. Grapevine cell cultures transformed with HsCYP1B1 produced about 20 mg/L culture of piceatannol, displaying a sevenfold increase in relation to wild-type cultures, and reaching an extracellular distribution of up to 45% of total production. The results obtained demonstrate the feasibility of this novel system for the bioproduction of natural and more bioactive resveratrol derivatives and suggest new ways for the improvement of production yield

VET students into technology companies: a microlearning digital course to train critical thinking skills

This microlearning course is designed to support VET graduates or students, especially those with fewer opportunities, who join a technology company at the beginning of their professional career. It has been developed within the framework of the Erasmus + project “VET STUDENTS İNTO TECHNOLOGY COMPANİES: A VET students mobility network in the technological sector through a virtual environment with specific materials for critical thinking”. This is an intiative co-financed by the Erasmus + Programme, with a personalized digital course format, to take into account both the previous training of the VET student or graduate and the type of company they will join. The course has in its sights to develop in the VET student the specific competences required by the technology company to address the problems typical of fields of leading technology innovation, as well as fitting in multidisciplinary teams. To do this, this course generates an innovative methodology in which the education itinerary is built based on previous knowledge of the student and the needs and work field of the technology company. Besides its contents strengthen critical thinking as an essential mechanism for work in both dynamic and technology sectors. For that purpose, the student is asked a series of questions in the form of problems that, in addition to being related to the study plans of VET studies, require for their solution the search for information, its analysis and many times the making of a decision or adopting a personal position on it. We aim with our training projects, within the Erasmus + program, to convince students that they are capable of going further and further in the development of their professional skills being the technology sector an acceptable option for them, making their work increasingly valuable for their inclusion, for their own personal development, for that of the company in which they work and for society. But for this certain skills are required, and one of the most important is learning to learn autonomously and to accurately analyse the information received and the decisions that are made from it. It is generally true that the problems that one encounters in professional practice are not going to be the ones that you were taught in your VET studies. Vocational training has to head for equipping students with the necessary tools to face the new problems that they will face in their job and to grow professionally every day. We intend to show how valuable critical thinking skills are in analysing our way of thinking and making decisions. In this paper we present examples of the exercises included in the course, how their approach and the processes that have led to a solution relate with the standards of critical thinking and the different levels of help that are offered to the student for their solution. The course is accessible from a digital educational software “ON YOUR SIDE: VIRTUAL ASSISTANT FOR EUROPEAN MOBILITIES IN TECHNOLOGICAL CENTERS” developed in the framework of this Erasmus+ project in order to develop cooperative work between students with fewer opportunities doing their internships in technology companies and their inclusion in new job posts. We will also present this software in a very summarized way in this article.This work has been funded by the Erasmus + program within the 2019-1-ES01-KA202-064569 project, Spanish Service for the Internationalization of Education (SEPIE
