No Evidence The Child Tax Credit Expansion Had An Effect On The Well-Being And Mental Health Of Parents.

In 1997 the US established the Child Tax Credit (CTC), which offers payments to parents of dependent children to help defray child-rearing costs. In 2021 a temporary expansion to the CTC increased the size of payments, extended payments to families with low or no earnings, and distributed payments monthly instead of annually. Quasi-experimental evidence from the US and experimental evidence from low- and middle-income countries shows that moderate-to-large cash transfers improve subjective well-being and mental health.

Enhanced nitrogen and carbon removal in natural seawater by electrochemical enrichment in a bioelectrochemical reactor.

Municipal and industrial wastewater discharges in coastal and marine environments are of major concern due to their high carbon and nitrogen loads and the resulted phenomenon of eutrophication. Bioelectrochemical reactors (BERs) for simultaneous nitrogen and carbon removal have gained attention owing to their cost efficiency and versatility, as well as the possibility of electrochemical enrich specific groups. This study presented a scalable two-chamber BERs using graphite granules as electrode material.

Genomic-Based Restriction Enzyme Selection for Specific Detection of Piscirickettsia salmonis by 16S rDNA PCR-RFLP.

The gram negative facultative bacterium P. salmonis is the etiological agent of Salmonid Rickettsial Septicaemia (SRS), a severe disease that causes important economic losses in the global salmon farmer industry. Despite efforts to control this disease, the high frequency of new epizootic events indicate that the vaccine and antibiotics treatments have limited effectiveness, therefore the preventive and diagnostic approaches must be improved.
