Body composition changes after covering on foot the Way of Saint James
Con este estudio, se pretende comprobar la existencia de cambios y
variaciones en la composición corporal de un grupo de adultos después de la
realización a pie de 5 etapas del Camino Primitivo de Santiago de Compostela
que discurre por la Provincia de Lugo. En él participaron 22 personas de
edades comprendidas entre los 21 y los 48 años, siendo el 22,72% varones y el
77,27% mujeres. Se realizaron medidas de bioimpedancia eléctrica con la
TANITA BC-418 en dos momentos diferentes (antes y después de realizar las
etapas del Camino de Santiago). Las modificaciones de las diferentes variables
medidas se analizaron y trataron con el paquete estadístico SPSS 20.0. Los
resultados encontrados muestran que con este tipo de trabajo aeróbico y esta
duración, en cierta medida se modificó la composición corporal de los sujetos
participantes. Sin embargo, se propone que para futuros estudios el tiempo de trabajo sea mayor y que la intensidad varíe, con el fin de comprobar si se
obtienen más resultados significativosWith this research, we want to check body composition changes and variations
in a group of adults after covering on foot 5 stages of the Primitive Way of Saint
James, which runs through the Lugo province. This research involved 22 people
between 21-48 years-old, 22.72% males and 77.27% females. Measurements
were performed with the bio-impedance TANITA BC-418 at two different
moments (before and after covering the Saint James` Way stages). Changes in
different measured variables were analyzed and treated with the SPSS
Statistics 20.0. Results show that, with this type of aerobic work and this
duration, body composition of people involved had some changes. However, it
is propose to increase work time and to vary intensity in future researches, with
the intention of prove if more significant results are obtainedS
ASTROD and ASTROD I -- Overview and Progress
In this paper, we present an overview of ASTROD (Astrodynamical Space Test of
Relativity using Optical Devices) and ASTROD I mission concepts and studies.
The missions employ deep-space laser ranging using drag-free spacecraft to map
the gravitational field in the solar-system. The solar-system gravitational
field is determined by three factors: the dynamic distribution of matter in the
solar system; the dynamic distribution of matter outside the solar system
(galactic, cosmological, etc.) and gravitational waves propagating through the
solar system. Different relativistic theories of gravity make different
predictions of the solar-system gravitational field. Hence, precise
measurements of the solar-system gravitational field test all these. The tests
and observations include: (i) a precise determination of the relativistic
parameters beta and gamma with 3-5 orders of magnitude improvement over
previous measurements; (ii) a 1-2 order of magnitude improvement in the
measurement of G-dot; (iii) a precise determination of any anomalous, constant
acceleration Aa directed towards the Sun; (iv) a measurement of solar angular
momentum via the Lense-Thirring effect; (v) the detection of solar g-mode
oscillations via their changing gravity field, thus, providing a new eye to see
inside the Sun; (vi) precise determination of the planetary orbit elements and
masses; (viii) better determination of the orbits and masses of major
asteroids; (ix) detection and observation of gravitational waves from massive
black holes and galactic binary stars in the frequency range 0.05 mHz to 5 mHz;
and (x) exploring background gravitational-waves.Comment: 17 pages, 6 figures, presented to The Third International ASTROD

Probabilistic reasoning with a bayesian DNA device based on strand displacement
We present a computing model based on the DNA strand displacement technique which performs Bayesian inference. The model will take single stranded DNA as input data, representing the presence or absence of a specific molecular signal (evidence). The program logic encodes the prior probability of a disease and the conditional probability of a signal given the disease playing with a set of different DNA complexes and their ratios. When the input and program molecules interact, they release a different pair of single stranded DNA species whose relative proportion represents the application of Bayes? Law: the conditional probability of the disease given the signal. The models presented in this paper can empower the application of probabilistic reasoning in genetic diagnosis in vitro
Home bias in officiating: Evidence from international cricket
We use data on leg before wicket decisions from 1000 test cricket matches to quantify the systematic bias by officials (umpires) to favour home teams. We exploit recent changes in the regulation of test cricket as a series of natural experiments to help to identify whether social pressure from crowds has a causal effect on home bias. Using negative binomial regressions, we find that home umpires favour home teams and that this effect is more pronounced in the later stages of matches
Composting the Invasive Toxic Seaweed Rugulopteryx okamurae Using Five Invertebrate Species, and a Mini-review on Composting Macroalgae
Since 2015, the invasive alga Rugulopteryx okamurae has explosively burst into the waters of the Strait of Gibraltar with serious repercussions on marine biodiversity, tourism and the fishing industry. Its elimination entails an enormous cost for the municipalities in the area and vermicomposting is proposed as a solution, but the anti-food secondary metabolites of the algae make it unfeasible. This work analyzed for the first time the bioremediation of this toxic algae using vermicomposting (Dendrobaena veneta and Eisenia fetida), blatticomposting (Eublaberus spp. “Ivory”), mealworms (Tenebrio molitor) and black soldier fly larvae (BSFL, Hermetia illucens). Both BSFL composting and blatticomposting are viable alternatives, as the toxics in the algae do not affect the long-term survival, growth or reproduction of these invertebrates. All other tested species do not resist consumption of R. okamurae. In parallel, a synthesis of current knowledge on marine macroalgae composting has been carried out. The results of this work will allow the use of insect farms in the upwelling areas that will eliminate algae, providing fertilizers and animal proteins that will be an economic aid to the municipalities in the affected coasts of southern Mediterranean Spain
La podredumbre del ajo causada por Fusarium proliferatum
La producción anual de ajo en España es de 154.587 t y su cultivo ocupa unas 15.900 ha distribuidas principalmente en Castilla La Mancha (53,1%), Andalucía (27,4%) y Castilla y León (9,1%). En Castilla La Mancha, la principal Comunidad productora, se ha cultivado en la presente campaña un 7 % más que en la campaña 2009/2010, siendo Albacete la provincia con mayor superficie cultivada de ajos con 4.750 ha, seguida de Cuenca con 2.200 ha. Las plagas y enfermedades en el cultivo del ajo suponen elevadas pérdidas económicas cada año en nuestro país. En 2008, distintos agricultores de varios municipios de Castilla y León detectaron bulbos de ajo del cultivar “Blancomor de Vallelado” que presentaban síntomas de podredumbre húmeda durante el almacenamiento. Posteriormente, en el año 2009, esta misma podredumbre se observó también en las provincias de Albacete y Cuenca en el cultivar “Morado de Pedroñeras”. Estudios sobre esta nueva enfermedad se están llevando a cabo en colaboración con productores castellanomanchegos pertenecientes a Coopaman SC
