El diazepan atenúa el efecto de contraste positivo sucesivo en el aprendizaje de evitación de un sentido

This study examined the influence of diazepam upon the successive positive contrast effect in one-way avoidance learning. The results showed that when injected with vehicle, a safety-time increment (from 1 to 30sec in the contrast group) during one-way avoidance learning led to a performance improvement, surpassing that of two control groups receiving the larger (30sec) or the lower (1sec) reward (safe time) from the beginning of training. However, when three similar groups were injected with diazepam, this contrast effect disappeared and learning was similar in all groups at the end of training. These results demonstrated a positive contrast effect in one-way avoidance learning and its attenuation by diazepam, bearing out previous findings about the joint influence of fear and relief upon acquisition and maintenance of the avoidance response. From an opponent process theory, the interaction between the motivational strength of fear and the incentive value of relief can explain not only positive and negative contrast effects, but also how anxiolytics attenuate both effects.Se analiza la influencia del diazepan en el contraste positivo sucesivo durante el aprendizaje de la tarea de evitación de un sentido. Los resultados mostraron que cuando se inyectaba a los animales “vehículo”, el incremento del tiempo en seguridad (de 1 a 30 seg en el grupo de contraste) durante el entrenamiento, generaba una mejora de la ejecución, que superaba la de los animales que recibían desde el principio sólo el reforzamiento mayor (30 seg) o el menor (1 seg). Cuando se inyectaba diacepam, ese efecto de contraste positivo se anulaba y la ejecución de los tres grupos (1-30, 1-1 y 30-30) era similar al final del entrenamiento. Los resultados muestran un claro efecto de contraste positivo y su atenuación por la acción del diazepan confirmando hallazgos previos sobre la influencia conjunta del miedo y la relajación en la adquisición y mantenimiento de la respuesta de evitación. A partir de la teoría emocional de los procesos oponentes, la interacción entre la fuerza motivacional del miedo y el valor de incentivo de la seguridad podría explicar los fenómenos de contraste positivo y negativo y su atenuación mediante ansiolíticos.

Deforestation impacts on bat functional diversity in tropical landscapes

"Functional diversity is the variability in the functional roles carried out by species within ecosystems. Changes in the environment can affect this component of biodiversity and can, in turn, affect different processes, including some ecosystem services. This study aimed to determine the effect of forest loss on species richness, abundance and functional diversity of Neotropical bats. To this end, we identified six landscapes with increasing loss of forest cover in the Huasteca region of the state of Hidalgo, Mexico. We captured bats in each landscape using mist nets, and calculated functional diversity indices (functional richness and functional evenness) along with species richness and abundance. We analyzed these measures in terms of percent forest cover. We captured 906 bats (Phyllostomidae and Mormoopidae), including 10 genera and 12 species. Species richness, abundance and functional richness per night are positively related with forest cover. Generalized linear models show that species richness, abundance and functional richness per night are significantly related with forest cover, while seasonality had an effect on abundance and functional richness. Neither forest cover nor season had a significant effect on functional evenness. All these findings were consistent across three spatial scales (1, 3 and 5 km radius around sampling sites). The decrease in species, abundance and functional richness of bats with forest loss may have implications for the ecological processes they carry out such as seed dispersal, pollination and insect predation, among others.

Does tillage influence physical- and chemical- related soil quality indicators equally?

Trabajo presentado en la EGU General Assembly 2019, celebrada en Viena del 3 al 8 de mayo de 2019.Soil degradation is linked with a loss of land′s actual or potential productivity. This process is a result of naturaland anthropogenic action being soil tillage one of the main drivers of the last. As a result, soil quality, whichmanifests soil′s capacity to produce ecosystem services and goods, can be compromised. There are severalindicators traditionally measured to characterize soil quality, either based on soil physical or chemical properties.Among soil physical properties, water flow features, as expressed through the soil water retention curve, aredirectly linked to the distribution of soil pores and can be useful to derive different indices (such as the S index)to evaluate soil′s quality. Organic matter, nutrients, and cation exchange capacity are also soil chemical propertiesaffecting soil quality.The main aim of this study was to evaluate the methodology based on the S index (Dexter, 2004) andselected soil (chemical and physical) properties at the short term under typical Mediterranean agriculturalconditions. For this reason, physical and chemical soil properties were measured in a short-term trial settle in twoolive orchards under different soil managements: tillage and cover crop and at two depths: surface (0-10 cm) anddepth (10-20 cm). In addition, water retention curves; water storage capacity; and soil porosity were characterized.At the two studied sites, changes in soil management, even after a short period of time, had a quick effectin chemical properties. However, soil′s pore size distribution, as quantified with the S index, did not showremarkable differences after changing soil management. This may be a consequence of the longer-term effectof changing soil management on water retention and transmission. Future research including more soil typesand assessing water-flow-related properties over a longer time interval, may well provide clearer results in theassessment of soil quality.Peer reviewe

Virtual reality to improve low-back pain and pelvic pain during pregnancy: a pilot RCT for a multicenter randomized controlled trial

A significant proportion of women experience low back and pelvic pain during and after pregnancy, which can negatively impact their daily lives. Various factors are attributed to these complaints, and many affected women do not receive adequate healthcare. However, there is evidence to support the use of different physiotherapeutic interventions to alleviate these conditions. Virtual reality is a promising complementary treatment to physiotherapy, particularly in improving pain perception and avoidance. The primary objective of this study is to evaluate the efficacy of a four-week program combining VR and physiotherapy compared to standard physiotherapy in pregnant women with low back and pelvic pain, in terms of improving pain avoidance, intensity, disability, and functional level. The study also aims to investigate patient satisfaction with the VR intervention. This research will be conducted through a multi-center randomized controlled clinical trial involving pregnant patients residing in the provinces of Seville and Malaga with a diagnosis of low back and pelvic pain during pregnancy. The alternative hypothesis is that the implementation of a Virtual Reality program in combination with standard physiotherapy will result in better clinical outcomes compared to the current standard intervention, which could lead to the development of new policies and interventions for these pathologies and their consequence

Characterization of lignin and lignin-derivatives from biomass. Application as expander of lead-acid battery

Expanders, as lignosulfonates, are crucial for a good performance of Pb/acid batteries. In the process of discharge, the Pb and the PbO2 go to PbSO4. The formed PbSO4 is adsorbed on the surface of the Pb electrode and dramatically reduces the lifetime of the battery by the formation of big PbSO4 crystals. In order to prevent that, the addition of expanders in the negative electrode is an economic solution to prevent the formation of big crystals. In this investigation, we propose the synthesis of several lignosulfonates obtained from lignin of many biomass origins. We have derivatized nine samples of lignin via microwave-assisted sulfonation, then we have characterized how efficient is the chosen synthesis method. The lignosulfonates obtained have been characterized by infrared spectroscopy (IR), proton nuclear magnetic resonance (1HNMR), two-dimensional correlated spectroscopy (COSY), and elemental analysis to acquire some relevant information about their structure in terms of functional groups. In this way, three commercial lignosulfonates, Vanisperse A, Indulin AT, and Oakwood, have been selected as references for our comparisons. Moreover, we have checked their electrochemical properties, using electrochemical techniques to compare their behavior with respect to the commercial lignosulfonates. Finally, we have selected one of them and we have tested its performance as an expander in a Pb/acid battery. That result is a very promising first approach, and we can conclude that lignosulfonates derivatives are a good and low-cost choice to improve the lifetime of Pb/acid batteries. In particular, it is shown that the incorporation of LignosB improves the cell formation as well as the first capacity (36.30% more) and the charge acceptance (63.16% more), being these relevant parameters in the performance of Pb/acid batterie

Internet of things applied to aquifer monitoring systems: a survey

The interaction between the oceanic and continental basins has been of general interest among the scientific community of multiple disciplines, from the physical perspective of how the interaction of fresh and salt waters mutually modulate their hydrodynamic behavior, and how this in turn determines the transport of sediments, nutrients and other tracers, in addition to inducing changes in the morphodynamics of the river and / or coastal-oceanic zone. Due to the importance of technology for the prevention of different environmental phenomena, this article aims to show the systematic review of the literature about different applications that allow software and hardware interaction to support decision making in the sense of aquifers

Multilayer Perceptron applied to the IOT systems for identification of saline wedge in the Magdalena estuary - Colombia

Maritime safety has become a relevant aspect in logistics processes using rivers. In Colombia, specifically in the Caribbean Region, there is the Magdalena River, a body of water that broadly borders the Colombian territory and is a tributary of various economic and public health activities. At its mouth, this river interacts with the sea directly, which generates a phenomenon called saline wedge, which is directly related to the sediments that must be continuously extracted and which threatens the proper functioning of the port from the city of Barranquilla, Colombia. Through this research, a network of sensors located in strategic places at the mouth of this river was generated, which allows predicting the behavior of the salt wedge. Using artificial neural networks, more specifically, the Multilayer Perceptron algorithm, it was possible to analyze the results of the implementation in light of the indicators or quality metrics, generating a highly reliable scenario that can be replicated in other sections of the river and in other aquifers
