Promoción turística sostenible: i-Naturhouse

La eficiencia energética y el aprovechamiento de las fuentes de energía naturales se han convertido en uno de los principales temas de investigación de Universidades y Gobiernos. Por ello, no es nada nuevo la presentación de un proyecto basado en una construcción que aprovecha los recursos naturales para la generación y posterior autoconsumo o venta de electricidad a la red. Nuestro proyecto es mucho más ambicioso y creemos que puede tener un fuerte impacto en un mercado global al utilizar todas las nuevas tecnologías existentes en campos como el bioclimatismo, energía solar, energía eólica, microcogeneración, telecomunicaciones, automatización, freecooling, iluminación y eficiencia energética. Deja de ser por tanto una solución parcial que aprovecha únicamente el conocimiento en algunos ámbitos de la ingeniería, para dar paso a una solución que se desarrolla en los campos de la Ingeniería Industrial en general (Mecánica, Energética, Eléctrica…etc.) las Telecomunicaciones, así como en el área de Economía y Finanzas. Nuestro proyecto aunque lo localizamos en la ciudad de Lleida, es un proyecto de alcance e impacto global, y en él analizamos en detalle cada uno de los puntos principales que intervendrían en este nuevo modelo de sensibilización de la sociedad hacia el consumo energético sostenible.El proyecto i‐Naturhouse es un trabajo de combinación de diferentes tecnologías con un fin común y en el cual éstas se combinan de forma equilibrada ofreciendo a la sociedad una herramienta que con un gran potencial, si tiene el alcance que se le proyecta. El proyecto ha sido dividido en 9 apartados. El primero es de introducción y contextualización para pasar a analizar posteriormente un caso concreto que ubicaríamos en la población de Lleida

孟子的德福一致观

孟子虽然没有专门讨论过什么是幸福,也没有专门论述过德性与幸福的关系,但根据其有关论述可见,孟子认为德福一致是实然的,即有德必有福,越有德性的人越幸福,二者是直接统一的。当然,德福一致只可能在孟子理想的王道社会中实现,包含了太多理想成分

The effects of whole-body muscle stimulation on body composition and strength parameters: a PRISMA systematic review and meta-analysis

Background: This systematic review and meta-analysis set out to determine the efficacy of whole-body muscle electrostimulation on body composition, strength, and muscle power in active and non-active adults (aged ≥18 years). Method: This review was reported in accordance with the Protocol Statement of Preferred Reporting Element Guidelines for Systematic Reviews and Meta-Analysis included controlled trials; whole-body electromyostimulation trials with at least 1 exercise and control group; participants >18 years old. Outcome measures were defined as standardized mean differences for muscle mass, body fat mass, strength, and power. Studies were searched in the following electronic databases: PubMed, Web of Science, Scopus, SPORTDiscus, and EMBASE for all articles published up to July 30, 2021. The risk of bias was assessed by 2 independent researchers using the Physiotherapy Evidence Database scale and Grading of Recommendations, Assessment, Development and Evaluations approach. Analyses were performed using the metafor package of the statistical software R (version 4.0.3; R Core Team, 2020). Random effects models, forest, and funnel plots to quantify the asymmetry associated with publication bias were fitted using the metafor library in R. Statistical heterogeneity was assessed using I 2 statistics. Results: In total, 26 studies representing 1183 participants were included (WB-electromyostimulation: n = 586 and control group: n = 597). The mean age of the participants ranged from a minimum of 20.4 to a maximum of 77.4 years old. Interventions lasted a minimum of 4 and a maximum of 54 weeks. Standardized mean difference was 0.36 (95% confidence interval [CI]: 0.16–0.57) for muscle mass, −0.38 (95% CI: −0.62–0.15) for body fat, 0.54 (95% CI: 0.35–0.72) for strength, and 0.36 (95% CI: 0.02–0.71) for power with significant differences between groups (all P < .04). I 2 revealed low heterogeneity of muscle mass (15%) and power (0%) between trials and medium heterogeneity of body fat (45%) and strength (55%). Conclusion: We concluded that WB-electromyostimulation has significant positive effects on muscle mass, body fat, strength, and power.info:eu-repo/semantics/publishedVersio

Manifestaciones hidrológicas e hidroquímicas de flujos subterráneos procedentes de formaciones poco permeables del terciario en el Somontano de Huesca

Presence of groundwater flow in the «somontano Oscense» area, proceeding from low permeability detritic tertiary rocks, is considered. It's given a grounwater flow model for these tertiary rocks. This model explains both water flow through them and water chemical characteristics. Groundwater flow has clear surface manifestations: it causes wet-areas (which are called «paules» in the area) with sodic waters; it makes appear saline, sodic or alkaline soils; and it modifies, too, water chemical composition of rivers in Somontano.Se considera la presencia en el Somontano Oscense de flujos de agua subterránea procedentes de materiales detríticos terciarios de baja permeabilidad. Se da un modelo de flujo de las aguas subterráneas en estos materiales que permite explicar tanto su fluencia hacia la superficie como sus características físico-químicas. Estos flujos se manifiestan en superficie, dando lugar a zonas húmedas naturales, paules, con aguas de composición sódica que provocan la formación de suelos salinos, sódicos o alcalinos; también se manifiestan modificando la composición química de las aguas de los ríos que atraviesan el Somontano

Aedes aegypti gut transcriptomes respond differently to microbiome transplants from field‐caught or laboratory‐reared mosquitoes

The mosquito microbiome is critical for host development and plays a major role in many aspects of mosquito biology. While the microbiome is commonly dominated by a small number of genera, there is considerable variation in composition among mosquito species, life stages, and geography. How the host controls and is affected by this variation is unclear. Using microbiome transplant experiments, we asked whether there were differences in transcriptional responses when mosquitoes of different species were used as microbiome donors. We used microbiomes from four different donor species spanning the phylogenetic breadth of the Culicidae, collected either from the laboratory or the field. We found that when recipients received a microbiome from a donor reared in the laboratory, the response was remarkably similar regardless of donor species. However, when the donor had been collected from the field, many more genes were differentially expressed. We also found that while the transplant procedure did have some effect on the host transcriptome, this is likely to have had a limited effect on mosquito fitness. Overall, our results highlight the possibility that variation in mosquito microbiome communities is associated with variability in host–microbiome interactions and further demonstrate the utility of the microbiome transplantation technique for investigating host–microbe interactions in mosquitoes

Interkingdom interactions shape the fungal microbiome of mosquitoes

Background: The mosquito microbiome is an important modulator of vector competence and vectoral capacity. Unlike the extensively studied bacterial microbiome, fungal communities in the mosquito microbiome (the mycobiome) remain largely unexplored. To work towards getting an improved understanding of the fungi associated with mosquitoes, we sequenced the mycobiome of three field-collected and laboratory-reared mosquito species (Aedes albopictus, Aedes aegypti, and Culex quinquefasciatus). Results: Our analysis showed both environment and host species were contributing to the diversity of the fungal microbiome of mosquitoes. When comparing species, Ae. albopictus possessed a higher number of diverse fungal taxa than Cx. quinquefasciatus, while strikingly less than 1% of reads from Ae. aegypti samples were fungal. Fungal reads from Ae. aegypti were < 1% even after inhibiting host amplification using a PNA blocker, indicating that this species lacked a significant fungal microbiome that was amplified using this sequencing approach. Using a mono-association mosquito infection model, we confirmed that mosquito-derived fungal isolates colonize Aedes mosquitoes and support growth and development at comparable rates to their bacterial counterparts. Strikingly, native bacterial taxa isolated from mosquitoes impeded the colonization of symbiotic fungi in Ae. aegypti suggesting interkingdom interactions shape fungal microbiome communities. Conclusion: Collectively, this study adds to our understanding of the fungal microbiome of different mosquito species, that these fungal microbes support growth and development, and highlights that microbial interactions underpin fungal colonization of these medically relevent species

Rheological Behaviour of an Insoluble Lemon Fibre as Affected by Stirring, Temperature, Time and Storage

The final publication is available at link.springer.comIn this work, the effect the preparation method (two different stirring systems at two temperatures and times), fibre concentration (between 2% and 3%), temperature (between 10 °C and 50 °C) and storage time (between 24 h and 50 days at 5 °C) had on the flow properties of a suspension of dietary lemon fibre prepared with a 45° Brix sucrose solution were evaluated. This information will be helpful in order to discover the best possibilities of using fibre to increase the viscosity of certain kinds of products, depending on the processing, storage and consumption conditions. The obtained results indicate that all the aspects which contribute to increase component solubilisation and the interaction of the insoluble fraction with the aqueous phase when preparing the suspension, such as a decrease in particle size, a rise in temperature or a longer homogenization time, entail a higher apparent viscosity. Moreover, favoring the solubilisation in the preparation process leads to a more stable rheological behaviour of the suspension during storage. As expected, the apparent viscosity of suspensions was dependent on the shear rate, concentration and temperature. A thixotropic behaviour of fibre suspension was only observed at a very low shear rate (5 s -1). © 2010 Springer Science + Business Media, LLC.Córdoba Sequeira, A.; Camacho Vidal, MM.; Martínez Navarrete, N.

A novel HPV 16 L1-based chimeric virus-like particle containing E6 and E7 seroreactive epitopes permits highly specific detection of antibodies in patients with CIN 1 and HPV-16 infection

<p>Abstract</p> <p>Background</p> <p>The presence of IgG antibodies to HPV-16 L1-virus like particles (VLPs) in serum has been reported as a result of persistent exposure to the virus and as a marker of disease progression. However, detection of VLP-specific antibodies in sera does not always indicate a malignant lesion as positive results may also be due to a nonmalignant viral infection. Furthermore, malignant lesions are associated with an increased antibody titer for E6 and E7 proteins. The aim of this study was to develop an ELISA using a novel chimeric virus-like particle (cVLP) encoding an L1 protein fused with a string of HPV-16 E6 and E7 seroreactive epitopes to its C-terminus to be used for detection of HPV-16 specific antibodies in patients with cervical intraepithelial lesion grade 1 (CIN 1).</p> <p>Results</p> <p>The sera of 30 patients with CIN 1 who also tested positive for HPV-16 DNA and of 30 age-matched normal donors negative for HPV infection were tested for the presence of IgG antibodies specific for either VLP-L1 (HPV-16 L1), gVLP (derived from Gardasil), or cVLP by ELISA. The cVLP-reactive sera yielded two distinct groups of results: (H) reactivity levels that presented very strong cVLP-specific titers, and (L) reactivity levels with significantly lower titers similar to those obtained with VLP-L1 and gVLP antigens. Additionally, the sera that presented the higher cVLP titers closely matched those that had significantly stronger reactivity to E6 and E7 epitopes. Interestingly, the samples with the highest titers corresponded to patients with the higher numbers of sexual partners and pregnancies. On the other hand only 4 out of the 12 sera that harbored antibodies with VLP neutralizing ability corresponded to the group with high cVLP antibody titers.</p> <p>Conclusion</p> <p>We report for the first time that chimeric particles containing HPV-16 L1 protein fused with E6 and E7 seroreactive epitopes enable much better detection of IgG antibodies in the sera of CIN 1 patients positive for HPV-16 infection than those obtained with VLPs containing only the HPV-16 L1 protein. We also found that the sera with higher cVLP antibody titers corresponded to patients with more sexual partners and pregnancies, and not always with to those with a high neutralizing activity. This novel assay could help in the development of a tool to evaluate cervical cancer risk.</p
