Development of a Biomass Gasification Process for the Coproduction of Methanol and Power from Red Sea Microalgae

In this study, an algae biomass gasification process using a dual fluidized bed with combined power and methanol cogeneration was developed. The gasification process was modeled using Aspen Plus and validated using experimental data of two microalgae species (Nannochloropsis oculata and Dunaliella salina) commonly found on the western coast of Saudi Arabia. The impacts of different operating condi

A Structural Equation Model Demonstrating the Relationship between Food Safety Background, Knowledge, Attitudes and Behaviour among Swedish Students

Traditionally, food safety knowledge has been seen as a factor in improving food safety behaviour. However, the relationship between knowledge and behavior is complex. The aim of the present study was to investigate self-reported data from 408 university students regarding food safety background, knowledge, attitudes, and behaviour using Structural Equation Model (SEM) to examine the influence of

On the Evolution of the Hubble Constant with the SNe Ia Pantheon Sample and Baryon Acoustic Oscillations : A Feasibility Study for GRB-Cosmology in 2030

The difference from 4 to 6 σ in the Hubble constant (H0 ) between the values observed with the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave Background obtained by the Planck data) still challenges the astrophysics and cosmology community. Previous analysis has shown that there is an evolution in the Hubble constant that scales as f (z) = H0/(1 + z)η, where H0

Care Home and Home Care Staff’s Learning during the COVID-19 Pandemic and Beliefs about Subsequent Changes in the Future : A Survey Study in Sweden, Italy, Germany and the United Kingdom

The aim of this study was to compare perceptions of learning from the COVID-19 pandemic and beliefs in subsequent changes for the future, among care home and home care staff, in four European countries. A 29-item on-line questionnaire was designed in English and later trans-lated into Swedish, Italian, and German on the impact of the pandemic on stress and anxiety. Anon-ymous data from care staff
