Morphological determination of the phototrophic community composition of biological soil crusts in coastal sand dunes in northern Germany
2022
This dataset comprises the microbial community composition of biological soil crusts in north-German sand dunes. For this we obtained enrichment cultures of phototrophic microorganisms, by placing fragments of biocrusts of the same Petri dishes as used for sequencing, in Petri dishes with Bold Basal (1N BBM) agarized medium (Bischoff and Bold 1963). Cultures were grown under standard laboratory conditions: with a 12-hour alteration of light and dark phases and irradiation of 25 μmol photons m-2 s-1 at a temperature 20 ± 5 ºС. Microscopic study of these raw cultures began in the third week of cultivation. Morphological examinations were performed using Olympus BX53 light microscope with Noma…
Study of Spanish grape mycobiota and ochratoxin A production by Isolates of Aspergillus tubingensis and other members of Aspergillus section Nigri.
2005
ABSTRACT The native mycobiota of five grape varieties grown in Spain has been studied. Four (Bobal, Tempranillo, Garnacha, and Monastrell) were red varieties and one (Moscatel) was white. The main fungal genera isolated were Alternaria , Cladosporium , and Aspergillus . The isolation frequency of Aspergillus spp. section Nigri in contaminated samples was 82%. Ochratoxin A (OTA) production was assessed using yeast extract-sucrose broth supplemented with 5% bee pollen. Cultures of 205 isolates from this section showed that 74.2% of Aspergillus carbonarius and 14.3% of Aspergillus tubingensis isolates produced OTA at levels ranging from 1.2 to 3,530 ng/ml and from 46.4 to 111.5 ng/ml, respecti…

Laboratory investigation into the development of resistance of Daphnia magna to the herbicide molinate.
2003
Daphnia magna (F0 generation) was exposed to different sublethal molinate concentrations (0, 3.77, 4.71, 6.28, 9.42, and 18.85 mg/L) during 21 days. Chronic toxicity tests, using the same herbicide concentrations, were also carried out during 21 days using neonates of F1 first brood (F1-1st) and F1 third brood (F1-3rd) offspring generations from the parentals (F0) preexposed to the herbicide. Finally, offspring (from F1-1st and F1-3rd broods) were transferred to herbicide-free medium during a 21-day recovery period. The alga Nannochloris oculata (5 x 10(5) cells/mL) was used as food in all the experiments. The effect of molinate on survival, reproduction, and growth was monitored for the se…
Estudio in vitro de la resistencia a la fractura mediante carga estática de materiales de restauración CAD-CAM para el sector posterior: influencia d…

RESUMEN DE TESIS DOCTORAL Doctoranda: Georgina García Engra Título de la Tesis: “Estudio in vitro de la resistencia a la fractura mediante carga estática de materiales de restauración CAD-CAM para el sector posterior: influencia del tipo de material y de la técnica de adhesión”. Introducción: El uso de restauraciones de recubrimiento parcial es una opción terapéutica que nos permite restablecer la función y estética del diente afecto mediante procedimientos de mínima invasión. En la actualidad, han surgido nuevos materiales de restauración para el sector posterior: cerámicas libres de metal y materiales híbridos. El tratamiento de estos materiales nos permite llevar a cabo técnicas de cemen…
Heuristics for solving the parameter tuning problem in motion cueing algorithms.
2017
[ES] Diversos tipos de plataformas robóticas son empleadas habitualmente para la generación de claves gravito-inerciales en simuladores. Además del control de los actuadores, dichas plataformas deben ejecutar complejos algoritmos de control conocidos como algoritmos de washout, que deben ser ajustados para que el movimiento generado sea similar al simulado. El ajuste de dichos algoritmos es complejo por el elevado número de parámetros que poseen. Además, dicho ajuste se ha venido realizando tradicionalmente de modo manual mediante evaluaciones subjetivas. En este trabajo, los autores proponen un método automático de ajuste basado en optimización heurística, métricas objetivas, y simulación …
Computers and young workers' wages in europe
2013
In this work evidence was found that wage differentials are in favour of those workers who have a home computer. In order to achieve these results the frontier stochastic method and the Kernel filter for analising errors was used. The research is based on the data provided by the survey of the European Community Household Panel (ECHP). Taking this survey as a starting point, a data panel is built containing those individuals that have remained in the sample for seven consecutives years. The results demonstrate that with the execption of Denmark, workers in each analised country, i.e. Germany, Italy, Spain and the United Kingdom have a wage premium measured by its closeness to the wage front…
Lotus spp: biotechnological strategies to improve the bioeconomy of lowlands in the Salado River Basin (Argentina)
2016
The Salado River Basin region is the most important livestock breeding area in Argentina, wherethe Lotus species has been traditionally cultivated as forages. Nearly 60% of their land surface is dominated by salt-affected soils with severe constraints for crop cultivation. In order to cope with that limitation, farmers have utilized species such as non-native L. tenuis (ex- Lotus glaber), which shows a very good adaptation. As a result, inter-seeding of L. tenuis has been proposed as a strategy of choice for improving forage production in marginal areas. The increase in soil quality by these means is achieved by an increment of the organic matter content, improvement of soil fertility as we…
Effect of cactus pear (Opuntia ficus-indica (L.) Miller) on the antioxidant capacity of donkey milk
2017
The cladodes of Opuntia ficus‐indica (L.) Miller were fed to lactating donkeys as an alternative food, in order to evaluate effects on the chemical composition and antioxidant activity of their milk. Lactating donkeys were divided into two groups: standard feeding and alternative feeding. With regard to chemical composition, no differences were observed. Total antioxidant capacity was constant in the standard feeding group, while it increased in the alternative feeding group: the radical scavenging activity increased from 95.53% to 96.62% in the ABTS test and from 28.40% to 33.33% in the DPPH test. This indicated that alternative feeding affects the antioxidant capacity of milk.
Effect of opuntia ficus-indica mucilage edible coating on quality, nutraceutical, and sensorial parameters of minimally processed cactus pear fruits
2021
Cactus pear (Opuntia ficus-indica (L.) Mill.) is a non-climacteric fruit with a relatively short postharvest life span, being very sensitive to water loss, darkening and decay. Cactus pear is a spiny fruit, and the presence of glochids limits fruit consumption and diffusion
