This study examines the influence of socio-economic status on truancy among secondary school students in Nigeria. The aim this article is, through a review literature methodology, to investigate extent which Nigeria could be reduced. findings show that came from moderate family background stayed at more than less privileged who low background. In view above points, it is recommended for vast punctuality adequately maintained within schools Nigeria, government should provide necessary...
Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) amplicon contamination was discovered due to next-generation sequencing (NGS) reads mapping in the negative controls. Environmental screening undertaken determine source of contamination, which suspected be evaporation during polymerase chain reaction (PCR) assays while using disease 2019 (COVID-19) ARTIC protocol. A decontamination strategy is hereby documented assist laboratories that may experience similar contamination....
