RESUMEN

To cope with the global climate crisis and assist in achieving the carbon neutrality, the use of biomass materials to fully or partially replace petroleum-based products and unrenewable resources is expected to become a widespread solution. Based on the analysis of the existing literature, this paper firstly classified biomass materials with potential application prospects in pavement engineering according to their application and summarized their respective preparation methods and characteristics. The pavement performance of asphalt mixtures with biomass materials was analyzed and summarized, and the economic and environmental benefits of bio-asphalt binder were evaluated. The analysis shows that pavement biomass materials with potential for practical application can be divided into three categories: bio-oil, bio-fiber, and bio-filler. Adding bio-oil to modify or extend the virgin asphalt binder can mostly improve the low temperature performance of asphalt binder. Adding styrene-butadienestyrene (SBS) or other preferable bio-components for composite modification will have a further improved effect. Most of the asphalt mixtures prepared by using bio-oil modified asphalt binders have improved the low temperature crack resistance and fatigue resistance of asphalt mixtures, but the high temperature stability and moisture resistance may decrease. As a rejuvenator, most bio-oils can restore the high and low temperature performance of aged asphalt and recycled asphalt mixture, and improve fatigue resistance. Adding bio-fiber could significantly improve the high temperature stability, low temperature crack resistance and moisture resistance of asphalt mixtures. Biochar as a bio-filler can slow down the asphalt aging process and some other bio-fillers can improve the high temperature stability and fatigue resistance of asphalt binders. Through calculation, it is found that the cost performance of bio-asphalt has the ability to surpass conventional asphalt and has economic benefits. The use of biomass materials for pavements not only reduces pollutants, but also reduces the dependence on petroleum-based products. It has significant environmental benefits and development potential.

RESUMEN

BACKGROUND: Insomnia is a common sleep disorder for adults with depression, with major impact on their quality of life. Previous trials suggest that listening to music may be helpful in the treatment of sleep disturbances in healthy populations, including students and elderly. In addition, small studies with clinical populations of traumatized refugees, adults with chronic insomnia and adults with depression insomnia add to the evidence base. However, the impact of music listening in the treatment of depression related insomnia is not well documented. OBJECTIVE: To examine the efficacy of music listening on sleep quality, symptoms of depression, and quality of life in adults with depression-related insomnia. METHOD: A single-center randomized controlled trial (RCT) in a two-arm parallel-group design is conducted and reported according to the CONSORT guidelines. The trial consists of an experimental group and a standard care control group. Both groups receive standard treatment for depression following Danish clinical guidelines in an outpatient psychiatry unit. The experimental group listens to music for a minimum of 30 minutes at bedtime for 4 weeks. DISCUSSION: This trial will provide information on the efficacy of music intervention as a non-pharmacological intervention in the treatment of depression-related insomnia. This study will provide novel knowledge concerning music medicine as an evidence-based treatment for depression. TRIAL REGISTRATION: Clinicaltrials.gov. ID NCT03676491, registered on 19 September 2018.

RESUMEN

BACKGROUND: No specific instrument has been developed for measuring alliance during music therapy. OBJECTIVE: To evaluate the feasibility of using the Helping Alliance Questionnaire II (HAq-II) as a self-report measure for individuals receiving treatment for a psychiatric disorder. Specifically, we examined the percent of patients who filled out the questionnaire, and when completed, whether there were any missing items. We also examined internal consistency and associations between patient variables and HAq-II scores. METHODS: Between October 2013 and April 2014, we invited 45 individuals with a psychiatric disorder, who were also receiving music therapy, to fill out the HAq-II. We also collected clinical data from each person's record. RESULTS: Thirty-one (69%) of the 45 invited patients filled out the HAq-II, and of those completed, only three had missing items. Of the 45 invited patients, thirty (67%) had a diagnosis of schizophrenia or other psychotic disorders, and 11 (24%) were diagnosed with other psychiatric disorders. In terms of diagnosis and other clinical variables, no statistically significant differences were found between the 31 patients who filled out the HAq-II and the 14 patients who did not return the questionnaire. The median HAq-II score was 5.11 (range 3.74-6.00), indicating a relatively high alliance. We did not find any statistically significant associations between the HAq-II scores and potential predictors of interest. The Cronbach's alpha was 0.85. CONCLUSIONS: Completion of the HAq-II was fairly high in this group of individuals with psychiatric diagnoses who were receiving music therapy. Internal consistency of the HAq-II was acceptable. Relatively high HAq-II scores suggest a high degree of therapeutic alliance, but the external validity of the HAq-II and the relationship between scores and therapy needs further evaluation.
