Reported COVID-19 cases and associated mortality remain low in many sub-Saharan countries relative to global averages, but true impact is difficult to estimate given limitations around surveillance and mortality registration. In Lusaka, Zambia, burial re
In the present as in the previous study, the mechanism underlying the effect of walk- ing speed kicking in the presence of adversity and buffer- ing the negative effects probably lies in the availability of a functional reserve that the individual can tap into. In addition to capturing health...
The biosensor detected S and N proteins of the virus in a buffer solution and saliva with LOD of 19 ng/mL and 8 ng/mL, respectively, in only 30 min, so the authors considered it to hold poten- tial for commercialization. However, studies are required to improve the signal-to-noise ...

Multilayer films with an active trilayer of Pt(3 nm)/Co(0.8 nm)/AlOx(3 nm) were deposited on a Ta (3.2 nm) buffer by sputtering at base pressure 10 À 8 Torr. These layered films were supported on bulk Si substrates for magneto-optic Kerr effect measurement and 35 nm thick ...
In the AD process, biochar increases the buffer capacity of the medium, inhibits compounds that could affect negatively the system (like organic acids), and helps to remove hydrogen sulphide which is a hazardous gas responsible for the corrosion of metallic infrastructures. Fly ashes act as a ...
To anticipate, adapt and respond to, and recover from disruptions, firms need to enhance supply chain (SC) resilience. The spread of the COVID-19 pandemic
DNA Extraction The DNA extraction was accomplished by centrifuging 10-mL samples at 2500 g for 10 min to collect cells. Super- natants were discarded, and the cells were resuspended in 200-µL TEG buffer (25 mM TRIS, 10 mM EDTA pH 8.0 and 50 mM glucose). Genomic DNA ...
