The study aimed to evaluate the superovulatory response and conception rate byapplying the technique of non-surgical embryo transfer in dairy cows of a commercialfarm in the Lima milkshed. Eight donor cows were used and distributed in two workingyears. Donors were synchronized with estrogens, progestagens and luteolitic agents,superovulated with 400 mg of FSH, and inseminated with two doses of frozen semen. Therecipient animals (n=28) were also distributed in two years. The Pre-synch protocol wasused for estrus synchronization in the first year and the CIDR-synch protocol in thesecond year. The expected day of heat presentation coincided for both donors andrecipients. The recovery of embryos was done seven days post service where embryoswere classified and immediately transferred. Pregnancy diagnosis by transrectalultrasonography was done at day 28 post transfer. A total of 23 embryos we...

El estudio tuvo como objetivo evaluar la respuesta superovulatoria y la tasa de concepción al aplicar la técnica no quirúrgica de transferencia de embriones en vacas lecheras de un establo comercial de la cuenca de Lima. Se utilizaron ocho vacas donadoras, distribuidas en dos años de trabajo. Estas fueron sincronizadas con estrógenos, progestágenos y agentes luteolíticos, superovuladas con 400 mg de FSHe inseminadas con dos dosis de semen congelado. Se utilizaron 28 receptoras, también distribuidas en dos años. En el primer año se sincronizaron con el protocolo Pre-synchy en el segundo año con el protocolo CIDR-synch. Se hizo coincidir el día esperado del celo de las donadoras y receptoras. Los embriones fueron recolectados en el día siete del servicio, se clasificaron y se transfirieron de inmediato a las receptoras. Eldiagnóstico de gestación se realizó mediante ultraso...

The main objective on this research is the development of finding the optimal parameters for a routing algorithm for network routers based on the ant algorithm described as AntNet. The optimum parameters for this type of algorithm improve a more efficient alternative to those given by the RIP, EIGRP and OSPF routing protocols, to be applied in a data network. This shall be tested in two networks and routers defined, taking the same characteristics for the three groups: RIP, OSPF and by the result provided by the genetic algorithm implemented using a static network. The system recognizes the best path between networks of routers, based on the principle of AntNet networks or networks of ants, which are the best way from exploring almost all roads, using estimergia to go there and make optimal. MatLab was used to detect the best way. Later this road was implemented in a real network data, s...

Breakthroughs in vitrification protocols and the results obtained after frozen embryo transfer have resulted in a different version of the assisted reproduction standard cycles: the “freeze-all” cycles. Regardless of their use beyond the usual indications (elevated progesterone, risk of hyperstimulation, among others), this new concept currently represents a common practice in many institutions and is applied to all patients. In this article, we will discuss the various factors that may have contributed to this change in policy and the scientific evidence for this topic. Based on this evidence, we will conclude if clinics should change their way of working from fresh embryo transfers to only transfer frozen embryos, or if we should maintain the standard protocol.

Las bandas transportadoras son indispensables en la minería, permitiendo el traslado eficiente de materiales pesados y contribuyendo a una producción fluida. Esta investigación se enfoca en mejorar la evaluación del empalme vulcanizado en caliente de estas bandas en una empresa minera, buscando reducir riesgos de fallas continuas en operación. El propósito del estudio es diseñar un protocolo específico para el empalme vulcanizado en caliente, con el fin de minimizar los riesgos de fallo continuo en una empresa minera en Ancash. A través de una metodología aplicada, se desarrolla un proceso que incluye la definición de materiales, análisis de fichas técnicas, normativas, manuales y el desarrollo del ensayo de tracción según la norma ISO 283. Como resultado, se diseñó un procedimiento de empalme vulcanizado en caliente de fajas transportadoras de minerales con núcleo text...

Drying is a method to preserve fruits, vegetables and fish by reducing their volume, their weight. Drying involves the application of energy to vaporize and mobilize the moisture content within porous products. During this process, heat and mass transfer occur simultaneously. The quality of dehydrated fruits, vegetables, and aromatic herbs is a problem closely related to the development and optimization of new drying techniques. This research work addresses the common drying methods applied to fruits, grains, fish and nutrients in relation to possible options to improve the quality of dried products using different drying techniques or their combination. In general, the drying technique is different for each of the materials studied and specific conditions should be recommended after a proper evaluation of the drying protocols. However, a novel or combined technique must ensure a high qu...
