Ovulatory and embryonic response to recombinant bovine somatotropin in goats super ovulated with FSHp

Artículo científico publicado en revista indizada.El objetivo del estudio fue evaluar el efecto de la somatotropina bovina recombinante (rBST) en la actividad ovárica, cantidad y calidad de embriones transferibles en cabras durante el anestro estacional. Se utilizaron 30 cabras multíparas sincronizadas con protocolo corto de CIDR y superovuladas con FSHp, asignadas a tres tratamientos (n = 10): T1 = control, sin rBST, T2 = 100 mg rBST y T3 = 200 mg rBST. Las variables cuantitativas se analizaron mediante prueba de Kruskal-Wallis; el porcentaje de estro y de embriones recuperados, mediante prueba de Chi - cuadrada. Las cabras del T3 tuvieron mayor número de CL, seguidas del T2 (p = 0.002). El número de embriones recuperados y de blastocitos fue mayor en T3 (p = 0.001). El número de mórulas fue mayor en T1 (p = 0.001). La aplicación de rBST al inicio del estro incrementa la actividad ovárica y la cantidad de embriones transferibles en cabras

Social Capital, Human Capital, and Sustainability: A Bibliometric and Visualization Analysis

[EN] Academic interest in social and human capital is growing significantly. Similarly, their relationship with sustainability is increasing, especially compared to sustainability¿s relationship with natural capital and financial and economic capital. Bibliometric and visualization research on these relationships is nonetheless insufficient. This study analyzes the evolution of the literature on natural capital, financial and economic capital, and social and human capital related to sustainability. On the other hand, the study presents a bibliometric analysis on social capital and human capital (SHC) related to sustainability. The article studies 635 references collected from theWeb of Science (WoS) Core Collection database and utilizes visualization of similarities (VOS) viewer program to graphically map the material. The analysis involves co-occurrence of keywords, co-citation, and co-authorship. The results reveal not only the state of the art and the leading trends, but also the evolution regarding impact, main journals, documents, topics, authors, institutions, and countries. The study provides researchers and practitioners with a visual and schematic frame of the research on this topic.This research was funded by Catedra de Empresa y Humanismo de la Universidad de Valencia grant number 3050361465.Garrigós Simón, FJ.; Botella-Carrubi, M.; Gonzalez-Cruz, T.

Electric-field tuning of the valley splitting in silicon corner dots

We perform an excited state spectroscopy analysis of a silicon corner dot in a nanowire field-effect transistor to assess the electric field tunability of the valley splitting. First, we demonstrate a back-gate-controlled transition between a single quantum dot and a double quantum dot in parallel that allows tuning the device in to corner dot formation. We find a linear dependence of the valley splitting on back-gate voltage, from $880~\mu \text{eV}$ to $610~\mu \text{eV}$ with a slope of $-45\pm 3~\mu \text{eV/V}$ (or equivalently a slope of $-48\pm 3~\mu \text{eV/(MV/m)}$ with respect to the effective field). The experimental results are backed up by tight-binding simulations that include the effect of surface roughness, remote charges in the gate stack and discrete dopants in the channel. Our results demonstrate a way to electrically tune the valley splitting in silicon-on-insulator-based quantum dots, a requirement to achieve all-electrical manipulation of silicon spin qubits.Comment: 5 pages, 3 figures.

Social Responsibility Practices in Companies: A Theoretical Review

The aim of this study is to understand, by a theoretical point of view, the potential impact of social responsibility practices in the business companies, taking in consideration several aspects and sundry approaches, by analysing the main defined strategies and policies. The concept is related with a philosophical and moral idea of corporate behaviour to the development of legally binding regulations, cultural and climate organizational characteristics. It is determined that development must be based on a sustainable economy while aligning these actions with the sustainable development goals established and at the same time the economic performance of the companies. For a social responsibility strategy, it is also crucial that the human resources departments, the commercial and marketing areas share and expose the actions that have an impact on the society where they are installed. Works on the establishment of this commitment and identification with the company through social responsibility policies have highlighted the role of management and leadership style in facilitating or not these processes.info:eu-repo/semantics/publishedVersio

LA EDUCACIÓN EN VALORES: AXIOLOGÍA, NATURALEZA Y DERECHO EDUCATIVO

La Educación en Valores y el Derecho Educativo, son dos elementos vinculados a la educación de personas e instituciones, con un peso propio, que se apoyan e interrelacionan necesariamente entre sí. Por esto, reflexionamos y referimos a la estimativa o axiología de la educación; a los valores que están presentes y su clasificación; a la relación entre la educación, la escuela, la experiencia vital y el mundo de los valores; a una aproximación a la Educación en Valores y sus modelos; a la didáctica y enseñanza de los valores en la escuela; así como al tratamiento del Derecho Educativo en su relación y apoyo a la Educación en Valores, como un importante componente del carácter multidimensional que posee

The reinsertion of controlled internal drug release devices in goats does not increase the pregnancy rate after short oestrus synchronization protocol at the beginning of the breeding season

Trabajo de investigación cuya temática es la sincronización del estro en ovejas de pelo.This study aimed to evaluate the effect of reinserting controlled internal drug release (CIDR) devices after fixed-time artificial insemination (FTAI) on pregnancy rates in goats. Oestrus was synchronized with a short (5 days) CIDR protocol, and FTAI was conducted 54 hours after CIDR removal. According to the reinsertion of CIDR after FTAI, goats were assigned to three treatments: G0 control group (n = 29), no CIDR reinsertion; G7 group (n = 27), CIDR reinserted 7 days; G14 group (n = 29), CIDR reinserted 14 days. Blood samples were collected to determine progesterone levels. Oestrus appearance (92.9%), interval of CIDR removal to oestrus (IRE = 34.1 ± 1.1 hours), interval of oestrus onset to artificial insemination (IEAI = 20.2 ± 1.0 hours), mean duration of oestrus (38.4 ± 1.4 hours), and pregnancy rates (61.0%) were similar (P > .05) among groups. Progesterone concentrations were higher (P  .05) for all groups. In conclusion, reinsertion of CIDR for 7 or 14 days after a short oestrus synchronization protocol and FTAI did not increase the overall pregnancy rate of goats

Influence of different levels of dried citrus pulp on in vitro ruminal fermentation kinetics of total mixed ration in goat rumen inocula

Inclusion of dried citrus pulp (DCP) at different levels: 0 (control), 10% (DCP10), 20 (DCP20), and 30% (DCP30) of the total mixed ration (TMR) was evaluated by in vitro gas production (GP), and ruminal fermentation patterns, in a completely randomized design. Rumen fluid was collected before the morning meal from 8 gestating goats (Boer×Saanen, body weight 3±2.3 kg). GP was recorded at 2, 4, 6, 8, 10, 12, 24, 48, 72, and 96 h of incubation. Ruminal fermentation parameters such as 96 h partitioning factor (PF96), in vitro organic matter digestibility (IVOMD), metabolizable energy (ME), short-chain fatty acids (SCFA), and metabolizable energy (ME) were also estimated. Inclusion of DCP linearly increased (P<0.01) cumulative gas production at 24, 48, and 96 h after inoculation, as well as asymptotic gas production (b). Rations at 30% and 10% DCP had the highest values of gas production, whereas control and 20% DCP presented the same values (quadratic effect P<0.01). Lag phase (L) decreased linearly (P<0.001) with DCP addition. IVDMD and IVOMD increased linearly (P<0.01) with the inclusion of DCP in rations. The ration at 30% DCP (DCP30) had the greatest value of ME and SCFA, but no differences were observed in the PF96 among treatments. The data suggest that the DCP30 ration had the best impact on rumen gas production and IVDMD, IVOMD, ME, and SCFA

Red de evaluación de cultivares de soja para el Noroeste Argentino: resultados de la campaña 2013/2014

La Estación Experimental Agroindustrial Obispo Colombres (EEAOC) nuevamente coordinó el desarrollo y evaluación de la Red de Evaluación de Cultivares de Soja para el Noroeste Argentino (NOA). Como en campañas anteriores, el Programa Granos de la EEAOC fue el responsable de coordinar los ensayos que, desde hace 17 campañas agrícolas, se vienen realizando ininterrumpidamente. El objetivo de esta red es evaluar el comportamiento agronómico de las variedades de soja que se encuentran disponibles comercialmente. La información que se obtiene resulta de utilidad para los productores de la región, constituyendo además una importante herramienta para la elección de los materiales a implantar en la siguiente campaña agrícola. Es necesario destacar la colaboración y el aporte que realizan productores, asesores, empresas privadas y técnicos del medio. La contribución que ellos vienen brindando desde el inicio de las evaluaciones resulta fundamental para el desarrollo y la continuidad en el tiempo de la Red de Evaluación de Cultivares de Soja.Fil: Devani, Mario R..

Waste paper ash as an alternative binder to improve the bearing capacity of road subgrades

The interest on alternative hydraulic road binders to replace cement is increasing these days aiming at reducing the carbon footprint of road projects. The PaperChain project, an EU funded project under the H2020 programme, tackles the use of one of these fly ashes, Waste Paper Fly Ash (WPFA), a waste stream coming from the energy recovery of paper rejects and sludge, as alternative binder for subgrade stabilisation and cement-modified subbase layers. WPFA has been extensively tested at laboratory scale and demonstrated at real scale in three field tests covering the three types of stabilised soils recognised in the Spanish Road Regulations, complying with all technical requirements. Nonetheless, the complete replacement of cement by WPFA is a challenge from the design point of view. This paper focuses on the construction and monitoring of one of those cases, specifically the one allocated for the pavement subgrade with the highest bearing capacity. Pairs of cement and WPFA-stabilised laboratory specimens have been tested showing a different hardening pattern and different reaction modulus evolution. Field-testing (load plate tests) and compressive resistance results confirmed this trend. These differences can result in positive effects on cracking development thanks to the slower hardening speed during the first days but the current design values should be reviewed when applied to WPFA, given the notable differences expected over the long term.This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 730305.
