Diversity of gut microbes is influenced by many aspects, including the host internal factors and even direct or indirect contact with other birds, which is particularly important for mixed-species wintering waterbird flocks. In this study, Illumina high-throughput sequencing was used to analyze the intestinal bacteria of the hooded crane and bean goose whose niches overlap at Shengjin Lake. We tested whether contact time enhances the trans-species spread of gut bacteria. Results indicate alpha-diversity and microbial composition displayed significant separation between the two hosts in every wintering period, although the number of bacteria types shared increased with increasing contact time. see more For the same species, with the lengthening of contact time, alpha-diversity and the number of operational taxonomic units (OTUs) in the host intestine augmented, and the common OTUs and structural similarity of microflora in the middle and late periods were more than in the early and middle periods. In addition, we found a very high proportion of shared pathogens. Our results indicate that, although intestinal microflora of different species were separated, direct or indirect contact in the mixed-species flock caused the spread of gut bacteria trans-species, indicating that more attention should be paid to intestinal pathogens in wild birds.Excessive sun exposure is the main avoidable cause of skin cancer. Outdoor sports performed without adequate photoprotection are risky practices in this respect. This study examines whether elite athletes in water sports (specifically surfing, windsurfing, and sailing) take appropriate measures to protect their skin from the sun, and whether there are differences in this respect according to age, gender, or sports discipline. This study is based on a questionnaire-based health survey. World championship competitors completed a self-administered questionnaire on their sun protection and exposure habits, as well as sunburns during the last sports season. In total, 246 participants, with an age range of 16-30 years, completed the questionnaire. Of these, 49.6% used inadequate sun protection. Those who protected their skin appropriately tended to be older than those who did not (average age = 23.28 and 20.69 years, respectively; p = 0.000). There were no significant differences in sun protection habits between male and female athletes. The rate of sunburn was very high (76.7%). A high proportion (22.5%) of participants never used sunscreen. Elite athletes in water sports are at real risk of skin lesions from overexposure to the sun, associated with inadequate photoprotection practices. Campaigns to raise awareness and to promote the early detection of skin cancer should target these risk groups.The aim of this work was to investigate the microstructure and the mechanical properties of laser-welded joints combined of Dual Phase DP800 and DP1000 high strength thin steel sheets. Microstructural and hardness measurements as well as tensile and fatigue tests have been carried out. The welded joints (WJ) comprised of similar/dissimilar steels with similar/dissimilar thickness were consisted of different zones and exhibited similar microstructural characteristics. The trend of microhardness for all WJs was consistent, characterized by the highest value at hardening zone (HZ) and lowest at softening zone (SZ). The degree of softening was 20 and 8% for the DP1000 and DP800 WJ, respectively, and the size of SZ was wider in the WJ combinations of DP1000 than DP800. The tensile test fractures were located at the base material (BM) for all DP800 weldments, while the fractures occurred at the fusion zone (FZ) for the weldments with DP1000 and those with dissimilar sheet thicknesses. The DP800-DP1000 weldment presented similar yield strength (YS, 747 MPa) and ultimate tensile strength (UTS, 858 MPa) values but lower elongation (EI, 5.1%) in comparison with the DP800-DP800 weldment (YS 701 MPa, UTS 868 MPa, EI 7.9%), which showed similar strength properties as the BM of DP800. However, the EI of DP1000-DP1000 weldment was 1.9%, much lower in comparison with the BM of DP1000. The DP800-DP1000 weldment with dissimilar thicknesses showed the highest YS (955 MPa) and UTS (1075 MPa) values compared with the other weldments, but with the lowest EI (1.2%). The fatigue fractures occurred at the WJ for all types of weldments. The DP800-DP800 weldment had the highest fatigue limit (348 MPa) and DP800-DP1000 with dissimilar thicknesses had the lowest fatigue limit ( less then 200 MPa). The fatigue crack initiated from the weld surface.Endocrine disrupting chemicals (EDCs) are exogenous chemicals which can disrupt any action of the endocrine system, and are an important class of substances which play a role in the Developmental Origins of Health and Disease (DOHaD) [...]."Age-Friendly Cities and Communities" is an initiative launched by the WHO in 2007 that has spread to more than 1000 cities and communities around the world. This initiative is based on an integrated physical and social environment for older people, and a model of participatory, collaborative governance. An enabling social environment setting is just as important as material conditions in determining well-being in later life. The objective of this study is to analyze the interaction between age-friendliness (physical and social) and subjective well-being in women and men aged 55 and over in the Basque Country. The methodology was based on a survey of a representative sample (n = 2469 individuals). In order to know the predictive power of age-friendliness over subjective well-being, linear regression models separated by gender were constructed. The predictive models of age-friendliness are composed by different variables for men and women. In both cases, the physical environment variables do not remain in the final model. Among the predictors of well-being in men, the coexistence stands out as a safety and support network. In women, the neighborhood has proved to be a very important resource. The conclusions of this study contribute to literature and interventions promoting more effective strategies that enhance older people well-being, considering the gender perspective.
