Productividad en la Industria de la Uva y la eficiencia de los recursos disponibles en el Valle de Guadalupe, Baja California, México

Actualmente los recursos naturales escasean de manera universal, ya sea por cambio climático o por el uso desmedido de ellos, las consecuencias son preocupantes y se vuelven cada vez más inevitables, sin embargo, para reducir el impacto se debe de contar estrategias de eficiencia del recurso. En el caso de Ensenada la industria vitivinícola en especial en el valle de Guadalupe contempla un entorno poco alentador ya que la disponibilidad del agua está marcando pautas atenuantes de crecimiento por una explotación desmedida del manto acuífero, asimismo el uso de suelo está siendo afectado por la población creciente, tal es el grado que el costo social representa un problema cada vez más agobiante en la población. La tecnología, la integración de las instituciones, el uso de sistemas sustentables para la eficiencia del Agua puede dar puntos para dar viabilidad a los problemas que se presentan en la cadena agroindustrial. El presente trabajo muestra las características productivas de la región, asimismo, contempla las listas que involucran el grado de competitividad de la industria acompañado de estrategias inductivas para el uso eficiente de los recursos marcando guías de oportunidad que contemple la eficiencia e integridad de los recursos que mejoren la posición del vino en el mercado

Valoración de la capacidad de resistir al esfuerzo como indicador de rendimiento

El principal objeto de este trabajo fue realizar una comparación entre los resultados de VO2máx obtenidos a través de dos test de resistencia inespecífica, uno de ellos continuo (George-Fisher) y otro con recuperación intermitente (Yo-Yo). Se contó con una muestra total de 16 sujetos, todos ellos varones con edades comprendidas entre los 16 y 18 años pertenecientes a un equipo de fútbol juvenil de la categoría 2ª Andaluza (Sevilla). Los resultados obtenidos indicaron que los valores de VO2máx no marcaban diferencias importantes entre el test George-Fisher (54.4 ± 4.9 ml/kg/min) y el test Yo- Yo (53.5 ± 4.6 ml/kg/min). Sin embargo, en la mayoría de los sujetos, el nivel de VO2máx en el George-Fisher (test continuo) es superior que en el Yo-Yo (test con recuperación intermitente). Es discutida la validez de los valores de VO2máx obtenidos a través de estos test de campo (métodos indirectos), siendo necesaria la utilización de pruebas en laboratorio (métodos directos) para la obtención contrastada de los mismos.The principal aim of this work was to realise a comparison between the results of VO2max obtained across two test of unspecific endurance, one of them constant (George- Fisher) and another with intermittent recovery (Yo-Yo). There was a total sample of 16 subjects, all of them males with ages included between 16 and 18 years belonging to a juvenile football team of the 2ª Andalusian category. The obtained results indicated that the values of VO2max were not marking importante differences between George-Fisher test (54.4 ± 4.9 ml/kg/min) and Yo-Yo test (53.5 ± 4.6 ml/kg/min). Nevertheless, in the majority on the subject, the level of VO2max in George-Fisher (constant test) is top that in Yo-Yo (test with intermittent recovery). It is discussed the validity of the values of VO2max obtained across these field test (indirect methods), being necessary the utilization of proofs in laboratory (direct methods) for obtaining confirmed of the same ones.Universidad de Sevilla.

Transformation of process water in the agri-food industry for its use in the agriculture in order to improve the agricultural processes.

The agricultural sector is facing a challenge because they need to increase the productivity of the agricultural crops due to the growing global population. Moreover, another problem is the negative impact that the chemical fertilizersand pesticides have in the ecosystems and human health. For this reason, investigation is needed to find other type of fertilizers to avoid this detrimental impact. Nowadays, biostimulants are playing an important role, they are considered as plant growth regulators because they enhance flowering, germination, plant growth and crop productivity and areenvironmental-friendly [1].In this study, the efficiency of the microalgaes and their use as biostimulants have been put to test. In order to prove the effects in the plant growth and crop productivity using lettuce as test crop, seven solutions have been prepared with different concentrations of natural fertilizer, microorganisms and microalgae. After that, these solutions weretested to prove if microalgae promoted seed germination and plant development in radishes' seed. Finally, cut flowers (daisies) were used to prove the efficiency of microalgaes in the maintenance of post-harvey, so four solutions which had water, aspirin, microalgae culture (with the microalgae) and seaweed liquid extract (without the microalgae) wereprepared.The results showed improve in the test crops as well as in the cut flowers. This can be explained because microalgae produce phytohormones like auxins, gibberelins, cytokinins and abscisc acid and other exogenous molecules as lipids, aminoacids, polysaccharide, etc. That can cause this beneficial effect [2].In conclusion, the microalgae seems to be a perfect substitute for the chemical fertilizers because of its benefits and non-harmful effects

It also examines the decline in poverty in Nicaragua from 1991 through World Bank indicators. Methods of measuring inequality and poverty such as the Gini coefficient, GDP per capita, and the incidence rate of poverty, as well as the poverty gap, are used. It includes the results of quantitative assessment of poverty and inequality, and concludes with a decline in poverty. There is evidence of a steady increase in real GDP and a steady trend in the unemployment rate

Characterization of high-power white leds for VLC applications

During the last years, visible light communications (VLC) have been proposed for providing connectivity while ensuring satisfactory illumination in both indoor environments and also specific outdoor scenarios without the need of deploying complex infrastructures for that purpose. Transmission for VLC is carried out through lightemitting diodes (LEDs), which correspond to semiconductors based on PN-junction materials with a direct gap. In this sense, the current flow plays a major role in the behavior and performance of these devices for VLC. Therefore, characterizing the electrical response of high-power white LED results mandatory for the successful implementation of VLC. At this point, it is worth noting that the electrical characterization is usually not available for high-power LEDs since, in fact, determining these characterization results challenging. In this sense, there exist some measurement instruments such as LCRs or impedance analyzers typically employed for characterizing materials and passive electrical components. However, these kinds of instruments are subject to a limited input impedance and a maximum value of forwarding current. In this work, the electrical characterization of the LED LXHL-BW02 of Luxeon is analyzed to show that typically commercial instrumentation for characterizing these devices is limited for high-power LEDs, which may provide polluted results when these limitations are not considered. After that, the characterization of the LXHL-BW02 based on a lock-in amplifier is proposed.This research was co-financed by Comunidad de Madrid and the FSE/FEDER Program under grant SINFOTON2-CM (S2018/NMT-4326), the Universidad Carlos III de Madrid under grant 2020/00038/001, and the Ministerio de Ciencia e Innovación and Agencia Estatal de Investigación (PID2019-109072RB-C31), and the European Regional Development Fund (ERDF) EXP 00119337/IDI-2019029

An enhanced method for dynamic characterization of high-power LEDs for visible light communication applications

Visible light communications (VLC) have been proposed for several applications beyond the traditional indoor scenarios, from vehicular to underwater communications. The common element in all these applications is the use of light-emitting diodes (LEDs) in which the forward current that flows through each LED plays a major role. Therefore, knowing the electrical equivalent of the LEDs is a useful tool for the proper design of the VLC systems. Currently, some measurement instruments exist, such as the LCR (inductance, capacitance, and resistance) meters or impedance analyzers to characterize the main parameters of the LEDs. However, these instruments and measurement procedures are subject to satisfying some requirements, such as a minimum value of the input impedance or the maximum forward current. In this work, the LED LXHL-BW02 is used to obtain its equivalent circuit, using different measurement methods and traditional methods of measurement with our proposed method. The equivalent model is implemented on the simulation tool LTSPICE. Our alternative method can be used for determining the electrical equivalent circuit of LEDs subject to high current variations at very high frequencies, in the MHz range, i.e., in an operating range for VLC applications.This research was co-financed by Comunidad de Madrid and the FSE/FEDER Program under grant SINFOTON2-CM (S2018/NMT-4326), the Madrid Government (Comunidad de Madrid) under the Multiannual Agreement with UC3M in the line of “Fostering Young Doctors Research” (GEOVEOLUZ-CM-UC3M), and in the context of the V PRICIT (Regional Programme of Research and Technological Innovation, and the Ministerio de Ciencia e Innovación and Agencia Estatal de Investigación (PID2019-109072RB-C31) and under the CDTI (Centre for the Development of Industrial Technology, Ministerio de Ciencia e Innovación) throughthe European Regional Development Fund (ERDF) EXP 00119337/IDI-2019029
