Introduction: COVID-19 is a novel infection caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2). This study was descriptive analysis the epidemiology of during first and second waves in Kwara State, North-Central Nigeria. Methods: investigated cases deaths State between 2nd April 2020 when recorded her index case till 15th September (first wave), 16th March 2021 (second wave). ...

Abstract Snowpit samples (n = 10) were collected (19 April 2008) from the snowpit sequences (depth 6.60 m) at Murodo-Daira site (36.58°N, 137.60°E, elevation of 2450 m a.s.l.) Mt. Tateyama (3015 m a.s.l.), central Japan. The first time, low molecular weight diacids, ω-oxoacids, pyruvic acid, and α-dicarbonyls measured for this sequence. Higher concentrations short-chain diacids (C2–C5) are obse...

objective: the rifampicin resistance and susceptibility of mycobacterium tuberculosis are caused by mutations in the 81-base pair region of the rpob gene encoding the b-subunit of rna polymerase. methods: isoniazid resistance of m. tuberculosis is related to mutations in inha , oxyr and ahpc genes which 30 to 90 percent of isoniazid resistance is occurred in 3015 codons of katg gene. the rpob a...

The influence of maleation on thermal and dynamic-mechanical properties of wood-PVC composites was investigated in this study. Experimental results indicated that maleation had a significant influence on most of the properties for wood-PVC composites. Storage modulus (E’), loss modulus (E”), and complex modulus (E*) of resultant wood-PVC composites were related to the retention levels and graft...

We propose a theoretical model based on the bank lending channel to assess the ability of lending facilities and swap programmes to a¤ect the credit interest rate. The model predicts the success of both unconventional monetary measures in reducing the credit interest rate under very general conditions. The comparison between measures reveals the outperformance of lending facilities over swap pr...

Retrograde exploration of the ureter and kidneys is currently a widely used and well-established procedure to deal with problems of a diagnostic and therapeutic nature with reduced invasiveness. The process of miniaturizing the instruments combined with the steady improvement in video quality has continuously amplified its potential applications, maintaining the procedure safe and rapid. During...

Recently, it has been shown that it is feasible to realize 29.5 Gb/in recording density employing hexagonal barium ferrite (H-BaFe) nanoplatelets [1]. Although H-BaFe nanoplatelets are a potential candidate for high density recording media, their greatest disadvantage is their dispersibility and agglomeration by forming poker-chip-like stacks due to mutual magnetic interactions [2-3]. To achiev...
