Hybrid Liquid Desiccant System Design and Operation Under High Latent Load Conditions in Taiwan

Hybrid Liquid Desiccant systems (HLDS) combine the liquid desiccant technology for dehumidification of air with conventional compression cycle technology for cooling. They are an alternative to conventional compression cooling systems, being more efficient and offering the possibility of independently control temperature and humidity. In this paper the design and operation of a HLDS is presented, for the air conditioning of a high latent load application with high ambient humidity levels. An analysis of the daily evolution of the performance of the system under different environmental conditions has been included. The innovative demonstration unit placed in Taiwan, in continuous operation since November 2015, achieved Energy efficiency Ratios (EER) up to 4.6.The authors would like to thank the support of the project “nanoCOOL” funded by the Seventh Framework Programme FP7/2007-2013, Project No. 314701

Efecto de la adición de grenetina en las propiedades reológicas y de textura de un panqué reducido en margarina

To increase the concentration of gelatin in a formulation for pound cake reduced in margarine and partially replaced by canola oil, there is a proportional increase in specific gravity, apparent viscosity and viscoelastic modules, decreasing the size and number of bubbles formed in the batter. In pound cake, there is a proportional decrease in volume and uniformity of the crumb and increase in the firmness, however, the addition of 1.25% of gelatin was the most accepted sensory formulation due to perceived a crumb more consistent and wet, so, the functionality of the gelatin as hydrocolloid, is limited to the final texture of the pound cake, concluding that it may be an alternative to improve the acceptability of a pound cake reduced in margarine, which is also of lower cost.The use of different hydrocolloids in the partial substitution of margarine by vegetable oils, are evaluated to achieve products with characteristics similar to the traditional product. The objective of this study was to evaluate the effect of the addition of different concentrations of gelatin (0%, 0.75%, 1.25%, and 2.0%) in pound cake formulation reduced in margarine and partially replaced with canola oil. It was determined specific gravity (SG), apparent viscosity, modules of viscoelasticity (G' and G") and number and size of air bubbles in the batter. In the pound cake was determined texture (TPA and sensory evaluation), crumb structure and moisture. By increasing the concentration of gelatin, it was observed a proportional increase of SG, apparent viscosity and elastic and viscous modules, predominating the viscous module with respect to elastic module, and a decrease in the number and size of air bubbles in the batter. In the pound cake, there was a proportional decrease in the volume and uniformity of the crumb, with respect to the size and number of cavities formed, however, sensorially, the most accepted formulation was the addition of 1.25% of gelatin because it perceives a more consistent and moist crumb, therefore, adding gelatin can be an alternative to improve the acceptability of a reduced pancake in margarine, which It's also less expensive.CONACy

Objective To detect the major challenges and needs reported by family member caregivers of people with spinal cord injury (SCI). Setting Family member caregivers of people with SCI and expert professionals were evaluated. This study was conducted in Spain, and most of the participants attended the National Paraplegics Hospital of Toledo. Methods We performed 25 semi-structured interviews. The data were analyzed from a phenomenological perspective using the Colaizzi method. Results The metamorphosis of the caregiver is a complex personal and family-related process. Analysis of the adjustment phase of the caregiving role allowed us to describe three stages, patterns, and trends. Five basic needs were identified. Conclusions People with SCI and their primary caregivers experienced changes in every sphere of their lives. Their most important needs were psychological support, social support, economic resources, information, training throughout the process of suffering, and the creation of informal groups of mutual aid

Hematopoietic stem cell transplantation in children with chronic granulomatous disease: the Spanish experience

Children; Chronic granulomatous disease; Graft failureNens; Malaltia granulomatosa crònica; Fracàs de l'empeltNiños; Enfermedad granulomatosa crónica; Fracaso del injertoIntroduction: Hematopoietic stem cell transplantation (HCT) can cure chronic granulomatous disease (CGD). However, transplant-associated morbidity or mortality may occur, and it is still controversial which patients benefit from this procedure. The aim of this retrospective study was to evaluate the outcome of pediatric patients who received HCT in one of the Spanish pediatric transplant units. Results: Thirty children with a median age of 6.9 years (range 0.6–12.7) were evaluated: 8 patients received a transplant from a sibling donor (MSD), 21 received a transplant from an unrelated donor (UD), and 1 received a haploidentical transplant. The majority of the patients received reduced-intensity conditioning regimens based on either busulfan plus fludarabine or treosulfan. Relevant post-HCT complications were as follows: i) graft failure (GF), with a global incidence of 28.26% (CI: 15.15–48.88), 11.1% in patients with MSD (1.64–56.70) and 37.08% in unrelated donors (19.33–63.17); and ii) chronic graft-versus-host disease (GVHD), with an incidence of 20.5% (8.9–43.2), 11.1% in patients with MSD (1.64–56.70) and 26.7% in unrelated donors (10.42–58.44). Post-HCT infections were usually manageable, but two episodes of pulmonary aspergillosis were diagnosed in the context of graft rejection. The 2-year OS was 77.3% (55.92–89.23). There were no statistically significant differences among donor types. Discussion: HCT in patients with CGD is a complex procedure with significant morbidity and mortality, especially in patients who receive grafts from unrelated donors. These factors need to be considered in the decision-making process and when discussing conditioning and GVHD prophylaxis

Intercultural and digital competence in teacher training from an international perspective: Poland Portugal, Slovakia, Spain and Russia

This article presents one of the studies from the European project IRNET, a network that pursues the development of new tools and methods for advanced pedagogical science in the field of ICT instruments, elearning and intercultural competences. We intend to explore the application of international and national policies of innovative, digital Education and intercultural competences in teacher training, as well as innovative educational practices. Another objective of the project is also to identify such practises and/or research projects in order to foster intercultural and digital competences in Spain, Poland , Slovak, Portugal and Russia. From a comparative perspective and on a qualitative paradigm, we have analyzed three comparative units that have allowed, among other things, us to look at the impact of projects financed with European or national funds as promoters of change and innovation related to intercultural training and technologies information. Finally, it has been observed that teaching trends point to a professorship endowed with skills that integrate intercultural models from the joint search for the school of the future, and for that online networks and virtual learning communities are key resources

Methods: Single-center retrospective study (2016–2023). Patients under 20 years who received MSCs for the treatment of HSCT-related complications were included. Results: Thirty patients (53.7% boys), median age at transplant 11 years (range 2–19) were included. MSCs indications were: graft-vs.-host disease (GVHD) in 18 patients (60%), of them 13 had acute GVHD (43.3%) and 5 chronic GVHD (16.7%); Grade 3–4 hemorrhagic cystitis (HC) in 4 (13.3%); poor graft function (PGF) in 6 (20%), 5 of them receiving MSCs with a CD34 stem cell-boost coinfusion; graft failure (GF) in 2 (6.7%), to enhance engraftment after a subsequent HSCT. Infusion-related-adverse-events were not reported. Overall response (OR) was 83% (25/30); 44% of responders (11/25) showed complete response (CR). OR for GVHD, HC, PGF and GF was 83.3%, 100%, 66.7% and 100% respectively. Response rate was 40% (95% CI: 20–55) and 79% (95% CI: 57–89) at 15 and 30 days. With a median follow-up of 21 months (IQR11–52.5), overall survival (OS) was 86% (95% CI: 74–100) and 79% (95% CI: 65–95) at 6 and 12 months post-MSCs infusion. Conclusion: In our study, the most frequent indication of MSCs was refractory aGVHD (43.3%). Response rates were high (OR 83%) and safety profile was good.The authors thank BST, Red Española de Terapias Avanzadas (RICORS TERAV, expedient no.

Effects of xylanase supplementation on feed intake, digestibility and ruminal fermentation in Rambouillet sheep

The present study aimed to investigate the effects of adding xylanase enzyme (XY) to a basal diet containing 300 g maize stover and 700 g concentrate/kg dry matter (DM) on feed intake, ruminal fermentation, total tract and ruminal digestibility, as well as some blood parameters. Four male Rambouillet sheep (39 ± 1·8 kg body weight), with permanent rumen and duodenum cannulae were used in a 4 × 4 Latin square design. Sheep were fed a basal diet without xylanase addition (control, XY0), or with the addition of xylanase at 1 (XY1), 3 (XY3) or 6 (XY6) μl/g of diet DM for 84 days, with four 21-day experimental periods. Feed intake, digestibility and rumen fermentation parameterswere determined on days 16–21 in each experimental period, and the apparent ruminal neutral detergent fibre (NDF) digestibilitywas determined on days 16 and 17. Treatments XY1 and XY3 increased feed intake,whereas digestibility was increased with XY6. Ruminal NDF digestibility increased when sheep were fed diets treated with xylanase. Ruminal pH, ammonia-N and acetic acid increased with xylanase treated diets. Propionic acid concentration increasedwith diet XY1 at 3 h post-feeding, but after 9 h post-feeding its concentration decreased in the rumen of sheep fed xylanase treated diets. Xylanase had no effect on blood urea, phosphorus and triglycerides. Addition of xylanase at 6 μl/g DM in a diet containing 300 g maize stover and 700 g concentrate/kg DM and fed to Rambouillet sheep improved feed digestibility and ruminal fermentation without affecting blood parameters
