This study aimed to enhance the initial adhesion performance of reactive polyurethane hot-melt adhesives by using a bio-based polycarbonate polyol instead of traditional polyester or polyether polyols and by incorporating thermoplastic polyurethane (TPU) in varied proportions. Adhesives synthesized from bio-based polycarbonate polyols and polypropylene glycol with MDI as the isocyanate were characterized chemically, thermally, and mechanically (FTIR, DSC, plate-plate rheology, DMA, and T-peel strength test). Adding 10-15 wt.

In the field of personalized medicine, biobanks play a key role through the provision of well-characterized and annotated samples protecting at the same time the right of donors. The Andalusian Public Health System Biobank (SSPA Biobank) has implemented a global information management system made up of different modules that allow for the recording, traceability and monitoring of all the information associated with the biobank operations.

Silvopastoral practices that integrate trees into livestock production could help address both local economic and wider environmental challenges.We aimed to assess the effects of silvopastoral practices on invertebrate communities on smallholder farms in Caquetá, Colombia.

This research therefore aimed to explore the negative attitudes or myths that serve to justify, minimize, and deny the experiences of cyber-sexual violence disclosed by women on Twitter. Using a thematic analysis, we analyzed 4,048 replies to 18 experiences reported on Twitter around the time of the International Day for the Elimination of Violence against Women.

Obtaining a large carboxyl group population over the surface is one of the main targets, as carboxyl group concentration in conventional graphene oxide is low among a majority of non-useful sp3-C-based functionalities. In the present work, we propose a selective method that yields an impressive increase in carboxyl group population using single-layer, thermally reduced graphene oxide as a precursor in a conventional Hummers-Offemann reaction.

These mixtures have been tailored to integrate an effective heating function in the materials. The manufacturing method for composite compounding and processing conditions significantly affects the electrical resistivity of the developed materials.

Methods: One day, cross-sectional study of patients with type 2 diabetes mellitus hospitalised in internal medicine departments. We recorded demographic and anthropometric variables, laboratory data and use of antihyperglycaemic drugs.
In this study, CNTs and graphite have been incorporated to provide electrical conductivity and self-heating capacity by Joule effect to an epoxy matrix. Additionally, both types of fillers, with different morphology, surface area and aspect ratio, were simultaneously incorporated (hybrid CNTs and graphite addition) into the same epoxy matrix to evaluate the effect of the self-heating capacity of carbon materials-based resins on de-icing and ice-prevention capacity. The self-heating capacity by Joule effect and the thermal conductivity of the differently filled epoxy resin were evaluated for heating applications at room temperature and at low temperatures for de-icing and ice-prevention applications.

Climate change and anthropogenic actions are diminishing oyamel fir forests in Mexico, putting pressure on the habitats of monarch butterflies. In the last decade, new colonies outside their usual range have been predicted through modeling and reported by the National Commission on Protected Areas of Mexico.

Nevertheless, their incorporation into cement presents some difficulties due to their tendency to agglomerate, yielding a non-homogeneous dispersion in the paste mix that results in a poor cement-CNTs interaction. This makes the surface modification of the CNTs by introducing functional groups on the surface necessary.

Exposure to sexist humor creates a context in which some men feel comfortable expressing aggressive tendencies toward women (i.e., self-reported rape proclivity).
View Article and Find Full Text PDFObjectives: Diabetes mellitus is associated with a marked increase in cardiovascular disease. In this study, we analysed the prevalence of diabetes mellitus in hospitalised patients in Spain in 2015 and the burden of associated cardiovascular disease.
Methods: By analysing the 2015 minimum basic data set (MBDS) of the Spanish Ministry of Health, we included all patients discharged with a diagnosis of diabetes mellitus.
Objectives: We developed a predictive model for the hospital readmission of patients with diabetes. The objective was to identify the frail population that requires additional strategies to prevent readmissions at 90 days.
Methods: Using data collected from 1977 patients in 3 studies on the national prevalence of diabetes (2015-2017), we developed and validated a predictive model of readmission at 90 days for patients with diabetes.
Two studies analyzed the influence of victim behavior, drink type, and observer rape myth acceptance (RMA) on attributions of blame to victims of sexual assault. In Study 1, people higher in RMA blamed the victim more when she accepted rather than rejected the aggressor's invitation to buy her a drink. In Study 2, we analyzed if the effects depended on who offered the invitation for a drink (a friend or aggressor).

Methods: We carried out a derivation rule for hypoglycemia using data from a nationwide retrospective cohort study of patients with diabetes or hyperglycemia carried out in 2014 (n=839 patients). The rule for hypoglycemia was validated using a second data set from a nationwide retrospective cohort study carried out in 2016 (n=561 patients).
Objectives: To analyse the efficiency of nurse prescription of the health products inherent to their care work, in Andalusia, Spain, between the years 2009-2015. To also analyse the discussions by the Medical Colleges Organisation and the Ministry of Health, Social Services and Equality, before the draft bill on nurse prescription and their outcome.

Aging may enhance both oxidative stress and bone-marrow mesenchymal stem-cell (MSC) differentiation into adipocytes. That reduces osteoblastogenesis, thus favoring bone-mass loss and fracture, representing an important worldwide health-issue, mainly in countries with aging populations. Intake of antioxidant products may help to retain bone-mass density.

Material And Methods: A multicenter cross-sectional study was conducted on patients with hyperglycemia hospitalized in the internal medicine departments of 44 hospitals evaluated in 2 time periods: 2014 (baseline period) and 2015 (postintervention period). The intervention consisted of the dissemination of the indicators obtained in 2014 and the objectives for improvement.
Exposure to some magazines aimed at young male readers- lads' mags-has recently been associated with behaviors and attitudes that are derogatory toward women, including sexual violence. In the present study, a group of Spanish adult men was exposed to the covers of a lads' mag while a second group was exposed to the covers of a neutral magazine. Results showed that, compared with participants in the second group, participants who were exposed to covers of lads' mags who also showed high rape myth acceptance and legitimized the consumption of such magazines reported higher rape proclivity in a hypothetical situation.

Methods: Crossover study using one-day surveys of all inpatients admitted to internal medicine wards from voluntary participating hospitals across Spain. Retrospective review of medical records was used to identify patients with hyperglycemia, causes for hospitalization, patients' demographic characteristics, appropriateness of glycemic monitoring and treatment during hospitalization.
The IFNL4 ss469415590 polymorphism, in high linkage disequilibrium with the IL28B rs12979860 variant, has been associated with hepatitis C virus clearance. We evaluated whether ss469415590 is associated with clinical and immunovirological parameters in human immunodeficiency virus-infected subjects. We found an independent association of the IFNL4 ss469415590 polymorphism with higher prevalence of AIDS-defining illnesses and lower CD4 T cell numbers.
